|---|---|---|---|
| CM-33012 | After you add an interface to the bridge, an OSPF session flap can occur. | 3.7.9-3.7.14 | |
| CM-33008 | Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed. CVE-2020-19667 Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c CVE-2020-25665 The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. This could cause impact to reliability. CVE-2020-25674 WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. CVE-2020-27560 ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service. CVE-2020-27750 A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould trigger undefined behavior in the form of values outside the range of type unsigned char and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27760 In GammaImage() of /MagickCore/enhance.c, depending on the gamma value, it’s possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. CVE-2020-27763 A flaw was found in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27765 A flaw was found in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27773 A flaw was found in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-29599 ImageMagick mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c. Vulnerable: <= 6.8.9.9-5+deb8u21 Fixed: 6.8.9.9-5+deb8u22 | 3.0.0-3.7.14 | |
| CM-33007 | The following vulnerability was announced in the apt packages: CVE-2020-27350: Missing input validation in the ar/tar implementations of APT, the high level package manager, could cause out-of-bounds reads or infinite loops, resulting in denial of service when processing malformed deb files. Vulnerable: <= 1.0.9.8.6 Fixed: 1.0.9.8.7 | 3.0.0-3.7.14 | |
| CM-32829 | The NET-SNMP-EXTEND-MIB, disabled in Cumulus Linux 4.2.1 and 3.7.14 to prevent security vulnerability CVE-2020-15862, is re-enabled read-only. | 3.7.14 | |
| CM-32810 | The following vulnerability has been announced in the libflac8 package: CVE-2020-0499: In FLAC__bitreader_read_rice_signed_block of bitreader.c, there is a possible out-of-bounds read due to a heap buffer overflow. This could lead to remote information disclosure with no additional execution privileges needed. However, user interaction is needed for exploitation. Vulnerable: 1.3.0-3 Fixed: 1.3.0-3+deb8u1 | 3.0.0-3.7.14 | |
| CM-32797 | The following vulnerabilities have been announced in curl: CVE-2020-8284: Vulnerability to malicious FTP server with PASV response with different IP address. CVE-2020-8285: Wildcard matching is vulnerable to denial of service by running out of stack space. Vulnerable: <= 7.38.0-4+deb8u18 Fixed: 7.38.0-4+deb8u19 | 3.0.0-3.7.14 | |
| CM-32757 | It was discovered that the clean_html() function of lxml, a Python library for HTML and XML processing, performed insufficient sanitisation for embedded Javascript code. This might lead to cross-site scripting or possibly the execution of arbitrary code. Vulnerable: <= 3.4.0-1+deb8u2 Fixed: 3.4.0-1+deb8u3 | 3.0.0-3.7.14 | |
| CM-32750 | In an EVPN Active/Active configuration, when one of the peers reboots and begins to refresh IP neighbor entries shared by the MLAG peer, some of these ARP messages might be dropped by the MLAG peer’s ARP policer. To work around this issue, increase the burst value of the ARP policers to 200 or higher. | 3.7.14 | |
| CM-32734 | CVE-2018-0734: A minor timing side channel attack was found in the OpenSSL DSA signature algorithm. The fix for that introduced a more severe regression that could also be exploited as a timing side channel attack. This update fixes both the original problem and the subsequent issue. CVE-2020-1971: A flaw in the GENERAL_NAME_cmp() function could cause a NULL dereference, resulting in denial of service. Vulnerable: <= 1.0.1t-1+deb8u12 Fixed: 1.0.1t-1+deb8u13 | 3.0.0-3.7.14 | |
| CM-32689 | CVE-2018-19139: Fix memory leaks by registering jpc_unk_destroyparms. CVE-2020-27828: Avoid maxrlvls more than upper bound to cause heap-buffer-overflow. CVE-2018-19543 and CVE-2017-9782: There is a heap-based buffer over-read of size 8 in the function jp2_decode in libjasper/jp2/jp2_dec.c. Vulnerable: <= 1.900.1-debian1-2.4+deb8u6 Fixed: 1.900.1-debian1-2.4+deb8u7 | 3.0.0-3.7.14 | |
| CM-32683 | When you change the SVI vlan-id value in the /etc/network/interfaces file, then run ifreload -a, the 802.1Q ID for the SVI in the kernel does not change.This operation is not supported in the kernel without recreating the SVI. To apply the change, run ifdown, then ifup for the SVI to recreate the interface. | 3.7.13-3.7.14 | |
| CM-32661 | On the Edgecore AS7312 switch, eth0 and swp use the same MAC address. | 3.7.14 | |
| CM-32609 | CVE-2020-25709, CVE-2020-25710: Vulnerabilities in the certificate list syntax verification and in the handling of CSN normalization were discovered in OpenLDAP, a free implementation of the Lightweight Directory Access Protocol. An unauthenticated remote attacker can take advantage of these flaws to cause a denial of service (slapd daemon crash) via specially crafted packets. Vulnerable: <= 2.4.40+dfsg-1+deb8u7 Fixed: 2.4.40+dfsg-1+deb8u8 | 3.0.0-3.7.14 | |
| CM-32597 | When you change the anycast address for the MLAG pair (clagd-vxlan-anycast-ip), high peak traffic occurs on the peer link interface of all MLAG switches. | 3.7.13-3.7.14 | |
| CM-32545 | If the FRR and MSTP processes go down, an SNMP TRAP is not generated even with the following configuration in the /etc/snmp/snmpd.conf file.proc watchfrr | 3.7.12-3.7.14 | |
| CM-32541 | After upgrading Cumulus Linux with the apt-upgrade command, then rebooting an MLAG pair, if there are no bonds configured with a clag-id, the clagd service has difficulty peering, and holds all MLAG interfaces and VNIs in a proto down state.To work around this issue, after upgrading both switches, restart the clagd service with the sudo systemctl restart clagd command on each MLAG pair. | 3.7.14 | |
| CM-32537 | CVE-2018-19787, CVE-2020-27783: The clean_html() function of lxml, a Python library for HTML and XML processing, performed insufficient sanitisation for embedded Javascript code. This could lead to cross-site scripting or possibly the execution of arbitrary code. Vulnerable: <= 3.4.0-1+deb8u1 Fixed: 3.4.0-1+deb8u2 | 3.0.0-3.7.14 | |
| CM-32529 | On Mellanox switches, the ASIC temperature sensor reading reports zeros. As a result, the fan speed is higher than normal. You can see the temperature reading in the output of the sensors command. | 3.7.14 | |
| CM-32516 | When using NCLU to add new BGP neighbors to existing configurations, the existence of address-family statements are ignored and the neighbors are added at the end of these lines. This might cause a problem if you try to activate these new neighbors in any of the existing address-family configurations. To work around this issue, configure the new BGP neighbors with vtysh. | 3.7.14 | |
| CM-32515 | Some issues have been found in qemu, a fast processor emulator. CVE-2020-25085 CVE-2020-25624 CVE-2020-25625 CVE-2020-25723 CVE-2020-27617: All issues are related to assertion failures, out-of-bounds access failures or bad handling of return codes. Vulnerable: <= 2.1+dfsg-12+deb8u17 Fixed: 2.1+dfsg-12+deb8u18 | 3.0.0-3.7.14 | |
| CM-32420 | When running traditional mode bridges at scale (for example, when you have more than 200 bridges and a large number of MAC addresses), MLAG bonds flap intermittently from dual to single connected, then back to dual connected, which causes a layer 2 loop and STP state changes. To work around this issue, either shut down one side of the MLAG bond or prune out VLANS over the bond. | 3.7.13-3.7.14 | |
| CM-32275 | After you reboot a Broadcom switch, switchd might fail to restart and you see logs in switchd.log similar to the following:… | 3.7.11-3.7.14 | |
| CM-32226 | If switchd successfully signals clagd that it is going down, clagd stops responding to keepalive echo requests from the peer instead of sending a good bye to the peer over both the peerlink and the backup switch. Eventually, the keepalive timer expires and the secondary switch becomes the primary, and brings the bonds and VNIs back up. However, if switchd does not successfully signal it is going down, (in the event of a crash), the primary switch continues to respond to keepalives, and the bonds and VNIs are down on both peers. | 3.7.12-3.7.14 | |
| CM-32225 | A slow memory leak is observed (1% per 14 hours) in kmalloc-256. To work around this issue, reboot the switch. | 3.7.12-3.7.14 | |
| CM-32217 | The IP address specified in the ip pim use-source command configured on the loopback interface should be inherited by unnumbered interfaces during their Primary IP address selection process. If ip pim use-source is configured on the loopback after an unnumbered interface has already selected their Primary IP address, the unnumbered interface does not update its Primary IP address to be the new use-source value until after there is a netlink update for that interface.To work around this issue, configure ip pim use-source on each unnumbered interface directly or ensure ip pim use-source is applied to the loopback before other unnumbered interfaces are enabled for PIM. | 3.7.13-3.7.14 | |
| CM-32169 | OpenSSH is vulnerable to CVE-2020-14145, as described in https://www.fzi.de/fileadmin/user_upload/2020-06-26-FSA-2020-2.pdf. This is an information leak in algorithm negotiation that can allow man-in-the-middle attacks on initial connection attempts without a previously stored server host key on the client. If desired, mitigation using UpdateHostKeys and HostKeyAlgorithms is also given in that paper. | 3.0.0-3.7.14 | |
| CM-32149 | If you try reconfigure a DHCP server after you delete the switch configuration with the net del all command, the dhcpd service fails because a duplicate process is running.To work around this issue, edit the /usr/lib/python2.7/dist-packages/nclu/plugins/dhcp.py file to change:DHCPD_PID=”-pf {0}” to: DHCPD_PID=”-pf {1}“ | 3.7.13-3.7.14 | |
| CM-32006 | Certain Dell S4048-ON switches show an incorrect vendor name and hang when you issue the reboot command. | 3.7.12-3.7.14 | |
| CM-31978 | On the Dell N3248PXE switch, fixed RJ45 interfaces with PoE neighbors can end up in Paused mode after a switchd restart, which blocks traffic on that interface. | 3.7.12-3.7.14 | |
| CM-31627 | On switches with the Spectrum ASIC, the IPv6 default route is present in the kernel but missing in hardware. | 3.7.11-3.7.14 | |
| CM-31605 | When you configure an SNMPv3 user with the net-snmp-config configuration command from the libsnmp-dev package, you get an error message similar to the one below:cumulus@switch:mgmt-vrf:~$ sudo net-snmp-config –create-snmpv3-user -a shaauthpass -x aesprivpass -A SHA -X AES userSHAwithAES To work around this issue, use the NCLU command to configure SNMPv3 user parameters; for example: cumulus@switch:mgmt-vrf:~$ net add snmp-server username user999 auth-md5 user999password encrypt-des user999encryption Alternatively, directly edit the /etc/snmp/snmpd.conf file as described in the documentation. | 3.7.13-3.7.14 | |
| CM-31420 | On a Cumulus Linux switch with high load averages, cl-support might end without creating a tar file and leave a temporary directory in /var/support undeleted. Subsequent runs of cl-support do not clean up this directory. | 3.7.13-3.7.14 | |
| CM-31407 | You cannot configure SNMPv3 trap-destinations in non-default VRFs with an authentication username that contains fewer than eight characters. | 3.7.12-3.7.14 | |
| CM-31404 | On the Delta AG7648 switch, the System LED and the Power LED do not display correctly. | 3.7.13-3.7.14 | |
| CM-31327 | After you manually edit the /etc/resolv.conf file to change or remove a VRF for a given DNS server, ifreload does not remove IP rules created for DNS servers in the VRF.To work around this issue, run the net add/del dns nameserver vrf <name> command to force the DNS configuration. | 3.7.13-3.7.14 | |
| CM-31322 | SNMP status might incorrectly reflect that a BGP neighbor is down due to an issue between bgpd and SNMP AgentX when the IP-FORWARD-MIB is also polled.To work around this issue, avoid polling IP-FORWARD-MIB objects. | 3.7.12-3.7.14 | |
| CM-31300 | If a neighbour contains a special character in PortID for LLDP, the net show interface command does not display the LLDP information or the command might fail. | 3.7.10-3.7.14 | |
| CM-31263 | RX_DRP on a bond interface increases without any data traffic while the slave port does not increase. | 3.7.12-3.7.14 | |
| CM-31232 | On the Dell N3048EP switch, the module information from SFP ports is not displayed in the l1-show command.To work around this issue, use the ethtool -m <interface> command. | 3.7.13-3.7.14 | |
| CM-31231 | On the Dell N3048EP switch, the module information from SFP ports is not displayed in the l1-show command.To work around this issue, use the ethtool -m <interface> command. | 3.7.13-3.7.14 | |
| CM-31222 | Tenant VRF BGP peers appear in the EVPN RMAC and nexthop tables, which causes the kernel RMAC to point at invalid IP address. | 3.7.12-3.7.14 | |
| CM-31150 | On the Mellanox SN2410 switch, you see switchd core and GBIN_MALLOC errors.To work around this issue, restart switchd. | 3.7.12-3.7.14 | |
| CM-31148 | Counters for IPROUTER rules do not increase when traffic is forwarded to the CPU because there is no IP neighbor. | 3.7.2-3.7.14 | |
| CM-31120 | In a traditional bridge configuration with ip-forward off, neighbors are synchronized to hardware with a switchd restart but are cleared when you flap the bridge interface. | 3.7.10-3.7.14 | |
| CM-31073 | When you set the sysctl settings net.ipv6.conf.all.accept_ra_defrtr (to prevent acceptance of IPv6 default route advertisements) and net.ipv6.conf.default.accept_ra_defrtr (set for newly created interfaces), if you create a new virtual interface, any pre-existing interface does not start accepting IPv6 default route avertisements again.To work around this issue, when you create a new virtual interface, set net.ipv6.conf.<interface>.accept_ra_defrtr to 0 for all interfaces and run sysctl -p --system. | 3.7.12-3.7.14 | |
| CM-31057 | The following vulnerability has been announced: CVE-2019-11360: A buffer overflow in iptables-restore in netfilter iptables 1.8.2 allows an attacker to (at least) crash the program or potentially gain code execution via a specially crafted iptables-save file. This is related to add_param_to_argv in xshared.c. | 3.0.0-3.7.14 | |
| CM-30879 | NCLU restarts FRR when removing a BGP VRF IPv4 aggregate-address command. | 3.7.12-3.7.14 | |
| CM-30863 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.0.0-3.7.14 | |
| CM-30832 | The Mellanox SN2700 and SN2410 switch intermittently reports PSU fan state changes with Unable to read from device/fan1_input/pwm1 syslog messages. | 3.7.11-3.7.14 | |
| CM-30580 | ifupdown2 does not account for link status or link down configuration when running dhclient. For example, ifupdown2 ignores link-down yes during ifup/ifreload and runs the DHCP module if inet dhcp is configured on the interface. ifupdown2 also runs the DHCP module even when the physical link configured for DHCP is down. | 3.7.12-3.7.14 | |
| CM-30422 | When you configure a bridge in the /etc/network/interfaces file, then try to reconfigure the bridge to be a VRF interface with the same name, ifreload/ifup commands fail with an invalid table id or unable to get vrf table id error. | 3.7.12-3.7.14 | |
| CM-30414 | If you toggle VRRP priority values between VRRP routers, then run a switchd restart, a few IPv6 VRRP instances might not converge. As a result, both the VRRP routers act as master routers for the impacted IPv6 VRRP instances. IPv4 VRRP instances are not affected.To work around this issue, remove, then add the VRRP configuration with NCLU commands or vtysh in FRR. | 3.7.13-3.7.14 | |
| CM-30296 | The net show configuration command provides the wrong net add command for ACL under the VLAN interface. | 3.7.12-3.7.14 | |
| CM-30286 | When you remove BFD configuration by editing the /etc/frr/frr.conf file and restarting FRR, you see a traceback.To work around this issue, either use NCLU or vtysh commands to remove the BFD configuration, or restart FRR with the new /etc/frr/frr.conf file. | 3.7.7-3.7.14 | |
| CM-30195 | On the Dell S3000 switch, after installing the Cumulus Linux 4.1.1 disk image without a license, the switch sends a link beat if a remote host port is configured. | 3.7.11-3.7.14 | |
| CM-30178 | NCLU tab completion for net show displays the text add help text instead of system Information for the system option. | 3.7.11-3.7.14 | |
| CM-30165 | When you use a phone with EAP and voice VLAN is configured (and MAB is not configured), after the phone authenticates, all tagged traffic from the phone is dropped. To work around this issue, enable MAB on the interface. | 3.7.12-3.7.14 | |
| CM-30103 | On a Broadcom switch with the Trident2+ ASIC, ACL rules for VLANs are not applied after a reboot and the counters remain at zero. To work around this issue, either do not set acl.non_atomic_update_mode = TRUE in the /etc/cumulus/switchd.conf file or run the cl-acltool -i command after the reboot to install the ACLs. | 3.7.12-3.7.14 | |
| CM-30101 | The NCLU net show bridge spanning-tree command displays the aging timer incorrectly. | 3.7.12-3.7.14 | |
| CM-29890 | Multiple paths to identical EVPN prefixes are either not displayed or not accepted into the l2vpn evpn table if they are received from a different AS. | 3.7.12-3.7.14 | |
| CM-29872 | Tab completion for the net show rollback description command returns information about a snapshot instead of context help.To work around this issue, run the net show commit history command to find descriptions instead of the net show rollback description command. | 3.7.12-3.7.14 | |
| CM-29871 | The net show rollback description <string> command returns an error even if the string matches a commit description.To work around this issue, look for your string in the output of the net show commit history command (or grep for it there) instead. | 3.7.12-3.7.14 | |
| CM-29779 | In LLDP, the snmp subagent loses all subsequent lldpRemSysName (1.0.8802.1.1.2.1.4.1.1.9) entries after an entry with a missing SysName is added.All the information from lldpctl is correct. Only the entries after the entry that is missing a SysName in lldpRemSysName disappear from the snmp subagent. | 3.7.12-3.7.14 | |
| CM-29759 | When you use nginx and restserver in management VRF to provide a REST API for the switch, nginx starts but restserver fails to start.To work around this issue, comment out the Requires= line in the /lib/systemd/system/restserver.service. For example:#Requires=nginx.service restserver.socket | 3.7.12-3.7.14 | |
| CM-29740 | The exim4 package available for optional installation on Cumulus Linux 3.x has the following vulnerability:DLA-2213-1 / CVE-2020-12783: Exim through 4.93 has an out-of-bounds read in the SPA authenticator that could result in SPA/NTLM authentication bypass in auths/spa.c and auths/auth-spa.c. The spa authentication driver is not enabled by default. Vulnerable: <= 4.84.2-2+deb8u6 Fixed: 4.84.2-2+deb8u7 | 3.0.0-3.7.14 | |
| CM-29667 | After installing Cumulus Linux on the Mellanox SN2100 switch, if you break out a port (for example, if you break out swp1 into four ports: swp1s0, swp1s1, swp1s2, swp1s3) in the /etc/cumulus/ports.conf file, then run the systemctl start switchd command, the update does not take effect.To work around this issue, run the systemctl restart switchd command. | 3.7.12-3.7.14 | |
| CM-29652 | The ACCTON-DIAG option under the Cumulus Linux GRUB menu does not work. When you select this option, you see the following error:error: invalid signature. | 3.7.12-3.7.14 | |
| CM-29594 | When you run an Ansible script to replace the /etc/network/interfaces file, then run the ifreload -a command, you see errors similar to the following:error: swp1s1.2: netlink: cannot set link swp1s1.2 up: operation failed with ‘Network is down’ (100) To work around this issue, run the ifreload -a command a second time. | 3.7.12-3.7.14 | |
| CM-29562 | If you have an SVI with multiple VRR IP addresses and try to delete one of the VRR configurations, net commit or ifreload -a returns an error. | 3.7.12-3.7.14 | |
| CM-29556 | The following vulnerability has been announced that affects ntp: CVE-2020-11868: ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. This affects: ntp-4.2.8p12 (possibly earlier) and ntp-4.2.8p13 The fix for https://bugs.ntp.org/3445 introduced a bug whereby a system that is running ntp-4.2.8p12 or p13 that only has one unauthenticated time source can be attacked in a way that causes the victim’s next poll to its source to be delayed, for as long as the attack is maintained. http://support.ntp.org/bin/view/Main/NtpBug3592 gives the following mitigations if it is not possible to upgrade to a version with the fix:
| 3.0.0-3.7.14 | |
| CM-29546 | In vtysh, if you configure, then remove a layer 3 VNI for a VRF, the VNI is removed from zebra even if the VNI interface still exists in the kernel. If you configure a layer 2 VNI as a layer 3 VNI by mistake, removing the layer 3 VNI binding removes it from zebra but EVPN-learned MACs and neighbors are not installed into the kernel. To work around this issue, delete, then re-add the missing VNI. For example: cumulus@switch:~$ sudo ifdown vni10100 If you flap the link with the ip link set vni10100 down; ip link set vni10100 up commands, zebra does not re-add the VNI. | 3.7.12-3.7.14 | |
| CM-29519 | The JSON format output of the net show bgp l2vpn evpn summary command shows the incorrect neighbour state. | 3.7.12-3.7.14 | |
| CM-29492 | When you create SPAN or ERSPAN rules in ebtables, the action fails to install if it is not in lowercase. Make sure that the SPAN or ERSPAN action is all lowercase; for example:[ebtables] | 3.7.12-3.7.14 | |
| CM-29367 | On switches with the Trident3 ASIC, PFC is not working as expected. If you set the PFC for only one CoS, pause frames are sent for all CoS traffic. | 3.7.11-3.7.14 | |
| CM-29309 | When Optimized Multicast Flooding (OMF) is enabled with the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/switchd.conf file, the switch continues to flood IPv6 multicast traffic to all slave ports when there is no MLD join receive. | 3.7.11-3.7.14 | |
| CM-29259 | You might see the following gport error messages in switchd.log:
These messages are harmless and can be ignored. | 3.7.12-3.7.14 | |
| CM-29165 | With FRR or OSPF, you might see an inconsistent link-state advertisement. For example, when you configure the OSPF default originate route as metric-type 1 with a specific metric, Cumulus Linux shows the default originate route as an external metric-type 2 route with the default metric in the database. This issue typically occurs when both IPv4 and IPv6 default routes exist in the routing table. | 3.7.12-3.7.14 | |
| CM-29148 | On MLX switches that contain an OSPF IP unnumbered neighborship with a high scale of prefixes being learned, a link flap might cause the neighbor entry to not be programmed in hardware. | 3.7.11-3.7.14 | |
| CM-29068 | On the Broadcom switch with the Trident3 ASIC, packet priority remark values assigned from each internal CoS value continue to work with default values; if you change the internal CoS value, the change does not take effect. | 3.7.11-3.7.14 | |
| CM-29043 | When a multipath route that contains an EVPN path exists together with an IPv4 BGP path in the VRF, the RMAC to VTEP binding is incorrect. This invalid entry occurs because Cumulus Linux treats IPv4 routes received over the eBGP IPv4 peering incorrectly in the VRF. To work around this issue, remove the unnecessary eBGP IPv4 peering. | 3.7.12-3.7.14 | |
| CM-29035 | When you upgrade Cumulus Linux on the EdgeCore AS7726-32X or AS7326-56X switch, you might see firmware errors similar to the following:W: Possible missing firmware /lib/firmware/tigon/tg3_tso5.bin for module tg3 You can safely ignore these error messages. | 3.7.12-3.7.14 | |
| CM-28944 | A change in a route map prefix list that should remove a route might not be reflected in the ospf6 database or in peers, and the route might not be deleted.To work around this issue, reenter the redistribute <connected\|static> route-map <route-map-name> statement in the configuration. | 3.6.2-3.7.14 | |
| CM-28940 | If you configure aggregate-address <address> summary-only before a component of the same aggregate is injected into the BGP table with the network or redistribute command, when you remove the aggregate-address configuration, the component stays suppressed; it is not advertised to peers. For example:Existing configuration: router bgp 1 If you add network 50.0.0.1/32, you see the following (expected) BGP table entries:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, Removing aggregate-address 50.0.0.0/8 summary-only at this point results in the following (unexpected) BGP table entry:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, To work around this issue, remove, then re-add the component prefix routes. | 3.7.12-3.7.14 | |
| CM-28816 | The following security advisory has been announced for bash: CVE-2019-18276 Qualys scan QID 372268 setuid vulnerability When bash or bash scripts are run setuid, bash is supposed to drop privileges, but does so incorrectly, so that an attacker with command access to the shell can use enable -f for runtime loading of a new builtin that calls setuid() to regain dropped privileges.To work around this issue, do not make bash or bash scripts setuid. | 3.0.0-3.7.14 | |
| CM-28754 | On switches with the Trident2+ ASIC, adding SPAN rules disables PBR rules. | 3.7.3-3.7.14 | |
| CM-28613 | In EVPN Active-Active (MLAG) environments, rebooting one member of an MLAG pair should result in the local MAC mobility sequence number reverting to 0. Sometimes a reboot of one MLAG peer results in the local MAC mobility sequence number being set to a non-zero value despite that no more mobility events occur. This issue is cosmetic only, as BGP does not advertise the incorrect sequence number and forwarding entries correctly point to the remote VTEP where the MAC is now located. | 3.7.12-3.7.14 | |
| CM-28611 | In an EVPN Active-Active (MLAG) environment, sometimes a local-to-remote MAC mobility event results in the local sequence number appearing higher than the remote sequence number in zebra. This issue is cosmetic only, as BGP does not advertise the incorrect sequence number and forwarding entries correctly point to the remote VTEP where the MAC is now located. | 3.7.12-3.7.14 | |
| CM-28596 | On the Dell Z9100 switch, 100G-SR4 modules might not link up reliably in certain ports. swp1, 2, 3, 9, 10, 23, 24, 30, 31, and 32 might be affected To work around this issue, move 100G SR4 modules to one of the ports not affected by this issue. | 3.7.11-3.7.14 | |
| CM-28533 | On the Lenovo NE0152T switch, one power supply (PSU2) always show as ABSENT in smonctl. | 3.7.11-3.7.14 | |
| CM-28465 | When you try to configure link-down on a parent interface of a subinterface configured in a VRF, you encounter an error. | 3.7.11-3.7.14 | |
| CM-28462 | On rare occasions, when you upgrade Cumulus Linux with the apt-get upgrade command, the upgrade fails and reports No space left on device. Checking the disk utilization shows that the disk is not full.To work around this issue, run the apt-get upgrade command again and reboot the device if prompted to complete the upgrade. | 3.7.10-3.7.14 | |
| CM-28441 | If a LLDP neighbor advertises a PortDescr that contains commas, ptmctl -d splits the string on the commas and misplaces its components in other columns. | 3.7.11-3.7.14 | |
| CM-28393 | On the Dell S5232F-ON switch, EVPN and dynamic VRF route leaking results in the CPU forwarding traffic to newly-learned type-2 routes. To work around this issue, restart FRR. | 3.7.9-3.7.14 | |
| CM-28372 | On the EdgeCore AS7326-56X switch, the default fan speed, which is defined in the thermal specification, results in excessive fan noise. | 3.7.11-3.7.14 | |
| CM-28212 | The hsflowd service sends an undefined header protocol 0 in the sampled flow sample to the collector, which is not recognized by the sFlow tool. You see errors similar to the following:Dec 20 08:43:27 netflow-nms sfcapd[3991]: SFLOW: readFlowSample_header() undefined headerProtocol = 0 | 3.7.11-3.7.14 | |
| CM-28080 | TACACS+ through ClearPass is not currently supported. Cumulus Linux sends authorization before authentication, but ClearPass does not accept an authorization before the user is authenticated. | 3.7.11-3.7.14 | |
| CM-28078 | On the Broadcom switch with the Trident3 ASC, packet priority remark values assigned from each internal CoS value continue to work with default values; if you change the internal CoS value, the change does not take effect. | 3.7.11-3.7.14 | |
| CM-28076 | After you hot swap a PSU, the decode-syseeprom -t psuX command shows the old PSU information (such as the serial number), until you run the decode-syseeprom --init command. | 3.6.0-3.7.14 | |
| CM-28061 | On switches with the Trident3 ASIC, PFC is not working as expected. If you set the PFC for only one CoS, pause frames are sent for all CoS traffic. | 3.7.11-3.7.14 | |
| CM-28003 | The FRR service does not provide a way for automation to know if the configuration applied properly. To work around this issue, execute the vtysh -f <file> command in the automation file before starting the FRR service to validate the functional configuration and return an error code. | 3.7.11-3.7.14 | |
| CM-27957 | If you have configured a higher number of ports and VLANs (ports x VLANs) or the switch is a lower-powered (CPU) platform, the switchd service might fail to send a systemd keepalive within the watchdog timeout value (2 minutes by default) and you see an error similar to the following:bq. systemd[1]: switchd.service watchdog timeout (limit 2min)! To workaround this issue, either reduce the number of configured interfaces and, or VLANs, or increase the systemd timeout for switchd.service.To increase the systemd timeout:

| CM-27937 | Debian security advisory DSA-4213 for qemu lists a number of security vulnerabilities. https://www.debian.org/security/2018/dsa-4213 One of the listed vulnerabilities is still present in the latest upstream version 2.1+dfsg-12+deb8u12 (the others have been fixed): CVE-2017-15124 Daniel Berrange discovered that the integrated VNC server insufficiently restricted memory allocation, which could result in denial of service. https://security-tracker.debian.org/tracker/CVE-2017-15124 | 3.0.0-3.7.14 | |
| CM-27793 | A security vulnerability has been announced in the cyrus-sasl2 (libsasl2-2 and libsasl2-modules) package. The libraries are installed by default on Cumulus Linux. CVE-2019-19906: Stephan Zeisberg reported an out-of-bounds write vulnerability in the _sasl_add_string() function in cyrus-sasl2, a library implementing the Simple Authentication and Security Layer. A remote attacker can take advantage of this issue to cause denial-of-service conditions for applications using the library. Vulnerable: 2.1.27+dfsg-1 Fixed: 2.1.27+dfsg-1+deb10u1 | 3.0.0-3.7.14 | |
| CM-27698 | SNMP ifLastChange reports link transitions when there are none. | 3.7.6-3.7.14 | |
| CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior:
| 3.7.11-3.7.14 | |
| CM-27581 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.14 | |
| CM-27530 | When hal.bcm.per_vlan_router_mac_lookup is set to TRUE in the /etc/cumulus/switchd.conf file, inter-VLAN traffic is forwarded to the CPU when associated VNI interfaces exist. | 3.7.10-3.7.14 | |
| CM-27522 | The NCLU command net show interface produces an error if bonds with no members exist.To work around this issue, remove the empty Bond interfaces from the /etc/network/interfaces file and run sudo ifreload -a. | 3.7.10-3.7.14 | |
| CM-27279 | When ECMP routes have both VXLAN (symmetric routing) and non-VXLAN paths, the non-VXLAN path is incorrectly installed in the RIB and FIB to point across VXLAN. The non-VXLAN next-hop will be installed as an offload entry in the neighbor table (ip neigh show) with a mac address of 00:00:00:00:00:00. | 3.7.3-3.7.14 | |
| CM-27192 | If you use NCLU commands to add a non-MLAG bond, then add an MLAG configuration, the net commit command fails. However, a subsequent net commit command succeeds. | 3.7.10-3.7.14 | |
| CM-27094 | On the Delta AG9032v1 switch, smonctl and sensors report inaccurate PSU current and power. | 3.5.0-3.7.14 | |
| CM-27018 | If you configure more than one VRR interface on an SVI interface, deleting one of the VRR addresses does not remove the interface/address. | 3.7.10-3.7.14 | |
| CM-26921 | If you delete an undefined bond, then add a bond slave, the net commit command fails. | 3.7.9-3.7.14 | |
| CM-26913 | FRR configuration commands for an SVI interface might have the \n misplaced in the output. For example:sudo sh -c “printf ‘interface 50\nvrf TEST description L3 routing interface\n’ » /etc/frr/frr.conf" should be: sudo sh -c “printf ‘interface 50 vrf TEST\ndescription L3 routing interface\n’ » /etc/frr/frr.conf" To work around this issue, configure the interface manually in the /etc/frr/frr.conf file. | 3.7.9-3.7.14 | |
| CM-26905 | When you update the hostname of a switch with the NCLU net add hostname <hostname> command, then run net commit, the lldpd service does not restart and other devices still see the old hostname.To work around this issue, run the sudo systemctl restart lldpd.service command. | 3.7.10-3.7.14 | |
| CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-3.7.14 | |
| CM-26655 | If you reconfigure an NTP server with NCLU using different trailing options after the IP address (such as iburst), an invalid configuration is added to the /etc/ntp.conf file. For example:net add time ntp server 1.2.3.4 iburst If you need to alter existing server configurations, first remove the server, commit, then re-add the server with any trailing options. | 3.7.9-3.7.14 | |
| CM-26599 | Auto-negotiation does not work with the QSFP28 cables and a remote system operating at 10G. Attempting to enable auto-negotiation with ethtool -s swp<#> autoneg on returns Operation not supported.To work around this issue, do not use auto-negotiation and set the local port speed to 10G. | 3.7.9-3.7.14 | |
| CM-26595 | The NCLU net show lldp command displays the speed of a ganged port group as the speed of one of the individual links, rather than the sum of their speeds. | 3.7.9-3.7.14 | |
| CM-26516 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.14 | |
| CM-26463 | The following CVEs affect the linux kernel package: CVE-2019-14821 CVE-2019-14835 CVE-2019-15117 CVE-2019-15118 CVE-2019-15902 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | 3.7.10-3.7.14 | |
| CM-26423 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.14 | |
| CM-26412 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.14 | |
| CM-26288 | On the Mellanox switch, static VXLAN tunnels incorrectly allow traffic from any remote tunnel IP address. | 3.7.8-3.7.14 | |
| CM-26256 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.14 | |
| CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.14 | |
| CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:-A FORWARD -i vni10 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.14 | |
| CM-26136 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.14 | |
| CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.14 | |
| CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-3.7.14 | |
| CM-25890 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.14 | |
| CM-25859 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.14 | |
| CM-25815 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.14 | |
| CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:ifdown vlan123 ; sleep 2 ; ifup vlan123 You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.14 | |
| CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.14 | |
| CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-3.7.14 | |
| CM-25740 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:cumulus@switch:~$ net add bridge mybridge vlan-protocol 802.1ad | 3.7.6-3.7.14 | |
| CM-25694 | If a packet is policed by ebtables, it does not increment an ACL drop on the ingress interface. Instead, it increments the TDBGC3/6 drop counter to the CPU. | 3.7.6-3.7.14 | |
| CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.14 | |
| CM-25400 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.14 | |
| CM-25397 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.14 | |
| CM-25001 | The following CVEs were announced in Debian Security Advisory DSA-444-1, DSA-4447-1 and affect the linux kernel and microcode. Package: linux CVE ID: CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091 Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. Contact your hardware ndor for microcode uppdates. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver. Fixed in version 4.19.76-1+cl4u1 | 3.0.0-3.7.14 | |
| CM-24894 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.14 | |
| CM-24799 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.14 | |
| CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-3.7.14 | |
| CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.14 | |
| CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.14 | |
| CM-24652 | In an EVPN environment, the centralized MAC address is not installed on the MLAG pair because Cumulus Linux does not perform an SVI MAC check per VLAN. This issue does not affect a pure distributed routing (symmetric or asymmetric) environment or a pure centralized routing environment. | 3.7.0-3.7.14 | |
| CM-24618 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:ERROR: No closing quotation See /var/log/netd.log for more details. | 3.6.1-3.7.14 | |
| CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.14 | |
| CM-24435 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect: net add routing route-map Proxy-ARP permit 25 match interface swp9-10 These commands are correct: net add routing route-map Proxy-ARP permit 25 match interface swp9 net add routing route-map Proxy-ARP permit 30 match interface swp10 | 3.7.2-3.7.14 | |
| CM-24426 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf <name> command just displays
Tab completion for the net add vrf <name> ip address <address> command works correctly. | 3.7.4-3.7.14 | |
| CM-24379 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.14 | |
| CM-24343 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.14 | |
| CM-24332 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.14 | |
| CM-24272 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface br0.100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# vrrp 1 advertisement-interval switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24271 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface vlan100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24270 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface swp4 switch(config-if)# vrrp 1 version 2 switch(config-if)# no vrrp 1 preempt switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24262 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto <iface> lines exist. | 3.7.3-3.7.14 | |
| CM-24241 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:cumulus@switch:~$ net del bgp neighbor fabric peer-group ‘router bgp 65001’ configuration does not have ‘neighbor fabric peer-group’ | 3.7.2-3.7.14 | |
| CM-24222 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.14 | |
| CM-24035 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.14 | |
| CM-23825 | The net add interface <interface> ptm-enable command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.14 | |
| CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev <interface> command. | 3.7.0-3.7.14 | |
| CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.14 | |
| CM-23665 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan <layer3-vni> bridge access <vlan>. This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.14 | |
| CM-23661 | On the Mellanox switch, when you configure a GRE tunnel, the traffic behind the local tunnel endpoint destined through the GRE tunnel is software-forwarded. | 3.7.2-3.7.14 | |
| CM-23651 | In an EVPN symmetric routing configuration, when an IP address is frozen, kernel neighbor table information and kernel VRF routing table information about the frozen IP address might be out-of-sync. | 3.7.3-3.7.14 | |
| CM-23584 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.14 | |
| CM-23570 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.14 | |
| CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.14 | |
| CM-23418 | For QSFP modules, the sudo ifdown command does not disable the Tx laser. | 3.7.2-3.7.14 | |
| CM-23417 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.14 | |
| CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.6.2-3.7.14 | |
| CM-23125 | The OpenSSL package on Cumulus Linux 3.x has a vulnerability similar to CVE-2018-0734. (The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key). According to Debian upstream, this version “is not vulnerable [to CVE-2018-0734 exactly]. Nevertheless, there is a bug fix that futher reduces the amount of leaked timing information. It got no CVE on its own and introduced this vulnerability.“ Vulnerable on CL3: 1.0.1t-1+deb8u12 | 3.0.0-3.7.14 | |
| CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.14 | |
| CM-23075 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:2018-11-10T23:35:30.992370-08:00 Dev dhcrelay: Listening on LPF/vlan.101/a0:00:00:00:00:51 2018-11-10T23:35:30.993472-08:00 Dev dhcrelay: Sending on LPF/vlan.101/a0:00:00:00:00:51 Eventually the dhcrelay service stops. | 3.7.1-3.7.14 | |
| CM-23021 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.14 | |
| CM-23004 | The local fallback account authenticates using the local password when the RADIUS or TACACS service is up. The expected behavior is for this to fail and only succeed when the RADIUS OR TACACS server fails to respond. | 3.7.1-3.7.14 | |
| CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.6.0-3.7.14 | |
| CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.14 | |
| CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.5.2-3.7.14 | |
| CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.6.2-3.7.14 | |
| CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.6.0-3.7.14 | |
| CM-22554 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 3.6.2-3.7.14 | |
| CM-22386 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.14 | |
| CM-22301 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.A $INGRESS_CHAIN –in-interface $INGRESS_INTF -m addrtype –dst-type IPROUTER -j POLICE –set-mode pkt –set-rate 400 –set-burst 100 These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 3.6.1-3.7.14 | |
| CM-22287 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 3.6.2-3.7.14 | |
| CM-22274 | To ease interoperation with non-Cumulus devices, it is possible to configure the route-target import and export values under the layer 2 VNI EVPN configuration. The same configuration does not work for both layer 2 VNI and layer 3 VNIs. Set the EVPN address-family within the VNI context when configuring the route-target in the layer 2 VNI. Set the EVPN address-family without the VNI context when configuring the route-target in the layer 3 VNI. | 3.6.0-3.7.14 | |
| CM-22252 | On the Edgecore OMP-800, there is no Power Supply information from the sensor or from smonctl. The platform driver has support for the PSUs but this was not added to the sensors infrastructure.This is a known limitation on the OMP-800 platform. | 3.6.2-3.7.14 | |
| CM-22228 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.14 | |
| CM-22205 | If a user is in vtysh when FRR is restarted, the running configuration in that vtysh session shows empty. | 3.6.2-3.7.14 | |
| CM-22138 | When you run the NCLU net show system command or the NetQ netq inventory command on the Edgecore OMP-800 switch, the output does not show any port or chip information. | 3.6.2-3.7.14 | |
| CM-22041 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.4.3-3.7.14 | |
| CM-22020 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.14 | |
| CM-21785 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 3.6.2-3.7.14 | |
| CM-21678 | On a Dell switch with a Maverick ASIC, NetQ might receive false alerts like the following via PagerDuty: cumulus@switch:~$ netq show sensors temp changes | grep absent | grep -v psu P2Leaf01 temp9 networking asic die temp sensor absent 43 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 47 105 100 5 Unable to read temp4_highest Add 9d:23h:26m:6s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to read temp4_highest Add 14d:22h:46m:45s This message might occur as a result of a timeout at the hardware level, or the switch might be reporting a failure to get a response. | 3.5.3-3.7.14 | |
| CM-21667 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 3.6.1-3.7.14 | |
| CM-21379 | If a primary route becomes unavailable (for example, you run ifdown on the switch port), the backup route remains inactive and is not installed into FIB.To work around this issue, configure routes as ECMP: cumulus@switch:~$ net del routing route 4.1.1.0/24 1.1.1.1 10 cumulus@switch:~$ net add routing route 4.1.1.0/24 1.1.1.1 cumulus@switch:~$ net commit | 3.5.3-3.7.14 | |
| CM-21332 | When two VLAN subinterfaces are bridged to each other in a traditional mode bridge, switchd doesn’t assign a gport to the subinterface, even though a gport is expected for each VLAN subinterface.To work around this issue, you can do one of two things:
| 3.5.3-3.7.14 | |
| CM-21058 | The advertised routes list may be empty for an EVPN peering even though the remote switch reports received routes. | 3.6.0-3.7.14 | |
| CM-20813 | Span rules matching the out-interface as a bond do not mirror packets. | 3.6.0-3.7.14 | |
| CM-20693 | In NCLU, you can only set the community number in a route map. You cannot set other community options such as no-export, no-advertise, or additive.This is a known limitation in network-docopt and is documented in the Cumulus Linux user guide. | 3.5.1-3.7.14 | |
| CM-20508 | The Cumulus-Resource-Query-MIB defines the ability to gather buffer utilization status but when these objects are polled, they return nothing. | 3.5.3-3.7.14 | |
| CM-20480 | The python-crypto package, which is not installed by default on Cumulus Linux, but is present in the repository to be installed, has the following security vulnerability in the version available for Cumulus Linux 3.x: CVE-2018-6594: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto’s ElGamal implementation. More information at https://security-tracker.debian.org/tracker/CVE-2018-6594 . | 3.0.0-3.7.14 | |
| CM-20033 | The VLAN interface stays up even though the physical link carrying the VLAN is admin or carrier down. | 3.5.2-3.7.14 | |
| CM-19788 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.5.0-3.7.14 | |
| CM-19724 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 3.5.2-3.7.14 | |
| CM-19454 | When you use NCLU to bring a bond admin down (net add bond <bond> link down), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown <bondname> command. | 3.5.0-3.7.14 | |
| CM-19006 | On the Broadcom Trident II+, Trident 3, and Maverick based switch, in an external VXLAN routing environment, when a lookup is done on the external-facing switch (exit/border leaf) after VXLAN decapsulation, the switch does not rewrite the MAC addresses and TTL; for through traffic, packets are dropped by the next hop instead of correctly routing from a VXLAN overlay network into a non-VXLAN external network (for example, to the Internet). This applies to all forms of VXLAN routing (centralized, asymmetric and symmetric) and affects all traffic from VXLAN overlay hosts that need to be routed after VXLAN decapsulation on an exit/border leaf, including:
For example, if the expected interface configuration is: auto swp3.2001 iface swp3.2001 vrf vrf1 address 45.0.0.2/24 # where swp3 is the external facing port and swp3.2001 is the VLAN subinterface auto bridge iface bridge bridge-vlan-aware yes bridge ports vx-4001 bridge-vids 4001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 Modify the configuration as follows: auto swp3 iface swp3 bridge-access 2001 # associate the port (swp3) with bridge 2001 auto bridge iface bridge bridge-vlan-aware yes bridge ports swp3 vx-4001 vx-16000000 bridge-vids 4001 2001 # where vx-4001 is the existing VNI and vx-16000000 is a new temporary VNI # this is now bridging the port (swp3), the VNI (vx-4001), # and the new temporary VNI (vx-16000000) # the bridge VLAN IDs are now 4001 and 2001 auto vlan2001 iface vlan2001 vlan-id 2001 vrf vrf1 address 45.0.0.2/24 vlan-raw-device bridge # create a VLAN 2001 with the associated VRF and IP address auto vx-16000000 iface vx-16000000 vxlan-id 16000000 bridge-access 2001 <… usual vxlan config …> # associate the temporary VNI (vx-16000000) with bridge 2001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 If an MLAG pair is used instead of a single exit/border leaf, the same temporary VNIs should be added on both switches of the MLAG pair. on the Broadcom Trident 3 switch. Note: This issue still exists on the Broadcom Trident II+ and Maverick-based switch. | 3.5.0-3.7.14 | |
| CM-18192 | In FRR, bgp_snmp does not show all BGP peers when peer groups used. | 3.7.11-3.7.14 | |
| CM-17934 | FRR tracks interface speed based on the value it learns from the Linux kernel for that interface. If the interface speed changes, FRR does not update its interface speed cache. This can lead to issues for routing protocols that derive metrics from interface speed as the cost can become out of sync with the interface speed. To work around this issue, manually define the routing protocol metric for these interfaces or restart FRR. | 3.7.6-3.7.14 | |
| CM-17557 | When sFlow is enabled, some sampled packets, such as IPMC, are forwarded twice (in the ASIC and then again through the kernel networking stack). | 3.4.0-3.7.14 | |
| CM-17494 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See Address Resolution Protocol in the Cumulus Linux user guide for more information. | 3.3.2-3.7.14 | |
| CM-16855 | If a two nodes on both sides of a link change from auto-negotiation off to auto-negotiation on for both sides during a short interval (around one second), the link might start flapping or stay down.To work around this issue and stop the flapping, turn the link down on the switch with the command ifdown swpX, wait a few seconds, then bring the link back up with the command ifup swpX. Repeat this on the other side if necessary. | 3.3.2-3.7.14 | |
| CM-16571 | NCLU cannot manage rsyslog to addresses routed via a VRF. In Cumulus Linux 4.0.0 and later, management VRF is enabled by default. To work around this issue, update the /etc/network/interfaces file to disable management VRF. | 3.4.3-3.7.14 | |
| CM-16461 | After booting a Cumulus VX virtual machine running the VMware OVA image, sometimes messages from sensors appear, indicating that the “Avg state” is critical, with all values displayed as 100.0. A cl-support is generated. | 3.4.2-3.7.14 | |
| CM-15812 | Multicast forwarding fails for IP addresses whose DMAC overlaps with reserved DIPs. | 3.2.1-3.7.14 | |
| CM-15094 | Counter samples for an 80G bond (2 x 40G) exported from the switch show an interface speed (ifSpeed) of 14.464Gbps. | 3.2.0-3.7.14 |

A remote attacker could potentially cause a denial of service or code execution during service discovery, due to a redundant disconnect management (MGMT) event. Vulnerable: <= 5.43-2+deb9u2~deb8u1 Fixed: 5.43-2+deb9u2~deb8u2 | 3.0.0-3.7.13 |
| CM-31981 | In an EVPN active/active environment, when one of the peers reboots and begins to refresh IP neighbor entries shared by the MLAG peer, some of the ARP messages might be dropped by the ARP policer of the MLAG peer. To work around this issue, increase the burst value of the ARP policers to 200 or higher. | |
| CM-31929 | VXLAN encapsulated traffic is not routed to the next hop because the destination VTEP IP address is mis-programmed on the switch, which decapsulates the traffic unexpectedly. To work around this issue, restart switchd. | 3.7.12-3.7.13 |
| CM-31863 | CVE-2020-14355: Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution. Vulnerable: <= 0.12.5-1+deb8u7 Fixed: 0.12.5-1+deb8u8 | 3.0.0-3.7.13 |
| CM-31696 | The following vulnerability has been announced in libproxy: CVE-2020-26154: A possible buffer overflow vulnerability in libproxy when a server serving a PAC file sends more than 102400 bytes without a Content-Length present.

| CM-31695 | The following vulnerability has been announced in the ruby2.1 packages: CVE-2020-25613: WEBrick (bundled along with ruby2.1) was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to “smuggle” a request. Vulnerable: <= 2.1.5-2+deb8u10 Fixed: 2.1.5-2+deb8u11. | 3.0.0-3.7.13 |
| CM-31674 | The following vulnerabilities have been announced in the python3.4 packages: CVE-2019-20907: Avoid infinite loop with crafted tar file by improving header validation. CVE-2020-26116: Avoid injection of HTTP headers via the HTTP method without rejecting newline characters. Vulnerable: <= 3.4.2-1+deb8u8 Fixed: 3.4.2-1+deb8u9 | 3.0.0-3.7.13 |
| CM-31673 | CVE-2016-7949, CVE-2016-7950: The libxrender library has issues in the way various X client libraries handle the responses they receive from servers. Insufficient validation of data from the X server could cause out of boundary memory writes in the libXrender library potentially allowing the user to escalate their privileges. Vulnerable: 0.9.8-1 | 3.0.0-3.7.13 |

| CM-33008 | Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed. CVE-2020-19667 Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c CVE-2020-25665 The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. This could cause impact to reliability. CVE-2020-25674 WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. CVE-2020-27560 ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service. CVE-2020-27750 A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould trigger undefined behavior in the form of values outside the range of type unsigned char and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27760 In GammaImage() of /MagickCore/enhance.c, depending on the gamma value, it’s possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. CVE-2020-27763 A flaw was found in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero.

A specially-crafted XBM image file could have caused a buffer overread. Vulnerable: <= 4.8.6+git64-g5dc8b2b+dfsg-3+deb8u2 Fixed: 4.8.6+git64-g5dc8b2b+dfsg-3+deb8u3 | 3.0.0-3.7.13 | 3.7.14 |
| CM-31120 | In a traditional bridge configuration with ip-forward off, neighbors are synchronized to hardware with a switchd restart but are cleared when you flap the bridge interface. | 3.7.10-3.7.14 | |
| CM-31086 | When you add a member to a bond that has a subinterface configured (such as peerlink.4094), the new member is assigned only the VLAN of the subinterface for forwarding. To work around this issue, bounce the bond or shutdown the new interface and use the remaining members over the bond. | 3.7.10-3.7.13 | 3.7.14 |
| CM-31073 | When you set the sysctl settings net.ipv6.conf.all.accept_ra_defrtr (to prevent acceptance of IPv6 default route advertisements) and net.ipv6.conf.default.accept_ra_defrtr (set for newly created interfaces), if you create a new virtual interface, any pre-existing interface does not start accepting IPv6 default route avertisements again.To work around this issue, when you create a new virtual interface, set net.ipv6.conf.<interface>.accept_ra_defrtr to 0 for all interfaces and run sysctl -p --system. | 3.7.12-3.7.14 | |
| CM-31057 | The following vulnerability has been announced: CVE-2019-11360: A buffer overflow in iptables-restore in netfilter iptables 1.8.2 allows an attacker to (at least) crash the program or potentially gain code execution via a specially crafted iptables-save file.

| CM-30885 | On a Mellanox switch with the Spectrum ASIC, you see LPC I2C driver errors similar to the following during boot:Jul 30 23:49:41.651453 mlx-switch systemd[1]: Started udev Kernel Device Manager. | 3.7.13 | 3.7.14 |
| CM-30879 | NCLU restarts FRR when removing a BGP VRF IPv4 aggregate-address command. | 3.7.12-3.7.14 | |
| CM-30863 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.0.0-3.7.14 | |
| CM-30858 | A vulnerability was found in curl, a command line tool for transferring data with URL syntax. curl is installed by default on Cumulus Linux.CVE-2020-8177: When using when using -J (–remote-header-name) and -i (–include) in the same command line, a malicious server could force curl to overwrite the contents of local files with incoming HTTP headers. Vulnerable: <= 7.38.0-4+deb8u16 Fixed: 7.38.0-4+deb8u17 | 3.0.0-3.7.13 | 3.7.14 |
| CM-30857 | An issue has been found in luajit, a just in time compiler for Lua.CVE-2020-15890: An out-of-bounds read could happen because __gc handler frame traversal is mishandled.Vulnerable: 2.0.3+dfsg-3 Fixed: 2.0.3+dfsg-3+deb8u1 | 3.0.0-3.7.13 | 3.7.14 |
| CM-30845 | The following vulnerabilities were reported against qemu, which is available in the repository for optional installation:CVE-2020-13659: address_space_map in exec.c in QEMU 4.2.0 can trigger a NULL pointer dereference related to BounceBuffer. CVE-2020-15863: stack-based overflow in xgmac_enet_send() in hw/net/xgmac.c. Vulnerable: <= 2.1+dfsg-12+deb8u15 Fixed: 2.1+dfsg-12+deb8u16 | 3.0.0-3.7.13 | 3.7.14 |
| CM-30832 | The Mellanox SN2700 and SN2410 switch intermittently reports PSU fan state changes with Unable to read from device/fan1_input/pwm1 syslog messages. | 3.7.11-3.7.14 | |
| CM-30827 | If the MAC address of an SVI changes, clagd does not update its permanent neighbor entry for the local interface, and it does not report the change to its MLAG peer. This leaves the MLAG peer in a state where its permanent neighbor for the MLAG peer’s SVI IP address continues to use the old MAC address, which causes routed traffic over this SVI to be dropped.To work around this issue, ifdown/ifup the SVI when a MAC address changes. | 3.7.12-3.7.13 | 3.7.14 |
| CM-30580 | ifupdown2 does not account for link status or link down configuration when running dhclient. For example, ifupdown2 ignores link-down yes during ifup/ifreload and runs the DHCP module if inet dhcp is configured on the interface. ifupdown2 also runs the DHCP module even when the physical link configured for DHCP is down. | 3.7.12-3.7.14 | |
| CM-30514 | In OVSDB high availability mode, deleting > 200 VLAN bindings might cause ovs-vtepd to crash. Limit the deletion to 200 or fewer VLAN bindings. | 3.7.12-3.7.13 | 3.7.14 |
| CM-30504 | When the OVSDB VTEP scale increases, the CPU utilization increases and eventually the switch (ptmd) fails to respond to the BFD, causing the BFD session to go down. As a result OVSDB cannot read the BFD socket status and outputs a warning in the ovs-vtepd debugs: PTM socket error: Bad file descriptor. | 3.7.12-3.7.13 | 3.7.14 |
| CM-30503 | In OVSDB high availability mode, if you create, then delete a binding, the FDB entry is not replaced and you see an error. | 3.7.12-3.7.13 | 3.7.14 |
| CM-30498 | There is a change to the default OVSDB bootstrapping process, where the script created now defaults to VLAN-aware bridge mode. If you want to use traditional bride mode, you need to force it by editing the ovs-vtep-ctl script generated by the bootstrap process. | 3.7.12-3.7.13 | 3.7.14 |
| CM-30486 | A host migrated to an 802.1X MAB port within the same broadcast domain fails to have the correct FDB entry installed if a dynamic FDB entry for that MAC address exists from previous connectivity in the broadcast domain. To work around this issue, manually delete the dynamic FDB entry that is associated with the uplink trunk port. | 3.7.12-3.7.13 | 3.7.14 |
| CM-30479 | When you restart clagd, the edge port setting on the peer link changes. | 3.7.2-3.7.13 | 3.7.14 |
| CM-30464 | The net show dot1x interface summary command output shows a MAC address with all zeros associated with a port. | 3.7.12-3.7.13 | 3.7.14 |
| CM-30422 | When you configure a bridge in the /etc/network/interfaces file, then try to reconfigure the bridge to be a VRF interface with the same name, ifreload/ifup commands fail with an invalid table id or unable to get vrf table id error. | 3.7.12-3.7.14 | |
| CM-30414 | If you toggle VRRP priority values between VRRP routers, then run a switchd restart, a few IPv6 VRRP instances might not converge. As a result, both the VRRP routers act as master routers for the impacted IPv6 VRRP instances. IPv4 VRRP instances are not affected.To work around this issue, remove, then add the VRRP configuration with NCLU commands or vtysh in FRR. | 3.7.13-3.7.14 | |
| CM-30296 | The net show configuration command provides the wrong net add command for ACL under the VLAN interface. | 3.7.12-3.7.14 | |
| CM-30286 | When you remove BFD configuration by editing the /etc/frr/frr.conf file and restarting FRR, you see a traceback.To work around this issue, either use NCLU or vtysh commands to remove the BFD configuration, or restart FRR with the new /etc/frr/frr.conf file. | 3.7.7-3.7.14 | |
| CM-30195 | On the Dell S3000 switch, after installing the Cumulus Linux 4.1.1 disk image without a license, the switch sends a link beat if a remote host port is configured. | 3.7.11-3.7.14 | |
| CM-30178 | NCLU tab completion for net show displays the text add help text instead of system Information for the system option. | 3.7.11-3.7.14 | |
| CM-30165 | When you use a phone with EAP and voice VLAN is configured (and MAB is not configured), after the phone authenticates, all tagged traffic from the phone is dropped. To work around this issue, enable MAB on the interface. | 3.7.12-3.7.14 | |
| CM-30141 | In an MLAG configuration with static VXLAN, static tunnels become unreachable. | 3.7.13 | 3.7.14 |
| CM-30103 | On a Broadcom switch with the Trident2+ ASIC, ACL rules for VLANs are not applied after a reboot and the counters remain at zero. To work around this issue, either do not set acl.non_atomic_update_mode = TRUE in the /etc/cumulus/switchd.conf file or run the cl-acltool -i command after the reboot to install the ACLs. | 3.7.12-3.7.14 | |
| CM-30101 | The NCLU net show bridge spanning-tree command displays the aging timer incorrectly. | 3.7.12-3.7.14 | |
| CM-29978 | The received PVST BPDU for a VLAN is flooded even though the ingress port doesn’t have the VLAN tagged. | 3.7.8-3.7.13 | 3.7.14 |
| CM-29890 | Multiple paths to identical EVPN prefixes are either not displayed or not accepted into the l2vpn evpn table if they are received from a different AS. | 3.7.12-3.7.14 | |
| CM-29872 | Tab completion for the net show rollback description command returns information about a snapshot instead of context help.To work around this issue, run the net show commit history command to find descriptions instead of the net show rollback description command. | 3.7.12-3.7.14 | |
| CM-29871 | The net show rollback description <string> command returns an error even if the string matches a commit description.To work around this issue, look for your string in the output of the net show commit history command (or grep for it there) instead. | 3.7.12-3.7.14 | |
| CM-29838 | CPU utilization may increase when clag-managed bond interfaces are operationally/LACP down but the physical carrier remains up on the bond member switchports. This condition occurs when clag bond redirection is enabled and bond members remain up while the parent bond does not negotiate LACP.This issue is resolved in Cumulus Linux 3.7.14. | 3.7.9-3.7.13 | 3.7.14 |
| CM-29830 | Unicast traffic from downlink hosts is flooded to multiple remote VTEPs, which might also cause high HwIfOutQDrops/TX_DRP on the uplink ports. To work around this issue, restart switchd. | 3.7.10-3.7.13 | 3.7.14 |
| CM-29779 | In LLDP, the snmp subagent loses all subsequent lldpRemSysName (1.0.8802.1.1.2.1.4.1.1.9) entries after an entry with a missing SysName is added.All the information from lldpctl is correct. Only the entries after the entry that is missing a SysName in lldpRemSysName disappear from the snmp subagent. | 3.7.12-3.7.14 | |
| CM-29759 | When you use nginx and restserver in management VRF to provide a REST API for the switch, nginx starts but restserver fails to start.To work around this issue, comment out the Requires= line in the /lib/systemd/system/restserver.service. For example:#Requires=nginx.service restserver.socket | 3.7.12-3.7.14 | |
| CM-29740 | The exim4 package available for optional installation on Cumulus Linux 3.x has the following vulnerability:DLA-2213-1 / CVE-2020-12783: Exim through 4.93 has an out-of-bounds read in the SPA authenticator that could result in SPA/NTLM authentication bypass in auths/spa.c and auths/auth-spa.c. The spa authentication driver is not enabled by default. Vulnerable: <= 4.84.2-2+deb8u6 Fixed: 4.84.2-2+deb8u7 | 3.0.0-3.7.14 | |
| CM-29667 | After installing Cumulus Linux on the Mellanox SN2100 switch, if you break out a port (for example, if you break out swp1 into four ports: swp1s0, swp1s1, swp1s2, swp1s3) in the /etc/cumulus/ports.conf file, then run the systemctl start switchd command, the update does not take effect.To work around this issue, run the systemctl restart switchd command. | 3.7.12-3.7.14 | |
| CM-29652 | The ACCTON-DIAG option under the Cumulus Linux GRUB menu does not work. When you select this option, you see the following error:error: invalid signature. | 3.7.12-3.7.14 | |
| CM-29594 | When you run an Ansible script to replace the /etc/network/interfaces file, then run the ifreload -a command, you see errors similar to the following:error: swp1s1.2: netlink: cannot set link swp1s1.2 up: operation failed with ‘Network is down’ (100) To work around this issue, run the ifreload -a command a second time. | 3.7.12-3.7.14 | |
| CM-29562 | If you have an SVI with multiple VRR IP addresses and try to delete one of the VRR configurations, net commit or ifreload -a returns an error. | 3.7.12-3.7.14 | |
| CM-29556 | The following vulnerability has been announced that affects ntp: CVE-2020-11868: ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. This affects: ntp-4.2.8p12 (possibly earlier) and ntp-4.2.8p13 The fix for https://bugs.ntp.org/3445 introduced a bug whereby a system that is running ntp-4.2.8p12 or p13 that only has one unauthenticated time source can be attacked in a way that causes the victim’s next poll to its source to be delayed, for as long as the attack is maintained. http://support.ntp.org/bin/view/Main/NtpBug3592 gives the following mitigations if it is not possible to upgrade to a version with the fix:
| 3.0.0-3.7.14 | |
| CM-29546 | In vtysh, if you configure, then remove a layer 3 VNI for a VRF, the VNI is removed from zebra even if the VNI interface still exists in the kernel. If you configure a layer 2 VNI as a layer 3 VNI by mistake, removing the layer 3 VNI binding removes it from zebra but EVPN-learned MACs and neighbors are not installed into the kernel. To work around this issue, delete, then re-add the missing VNI. For example: cumulus@switch:~$ sudo ifdown vni10100 If you flap the link with the ip link set vni10100 down; ip link set vni10100 up commands, zebra does not re-add the VNI. | 3.7.12-3.7.14 | |
| CM-29525 | The asic-monitor.service fails when you configure /etc/cumulus/datapath/monitor.conf with monitor.histogram_pg.collect.port_group_list = <span class="error">[all_packet_pg]</span> and there is traffic passing through the buffer. When the service fails, you see the following traceback in journalctl:asic-monitor[7389]: asic-monitor-module INFO: 2020-05-01 18:28:12.548734: Egress queue(s) greater than 500 bytes in monitor port group histogram_pg | 3.7.11-3.7.13 | 3.7.14 |
| CM-29519 | The JSON format output of the net show bgp l2vpn evpn summary command shows the incorrect neighbour state. | 3.7.12-3.7.14 | |
| CM-29492 | When you create SPAN or ERSPAN rules in ebtables, the action fails to install if it is not in lowercase. Make sure that the SPAN or ERSPAN action is all lowercase; for example:[ebtables] | 3.7.12-3.7.14 | |
| CM-29367 | On switches with the Trident3 ASIC, PFC is not working as expected. If you set the PFC for only one CoS, pause frames are sent for all CoS traffic. | 3.7.11-3.7.14 | |
| CM-29309 | When Optimized Multicast Flooding (OMF) is enabled with the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/switchd.conf file, the switch continues to flood IPv6 multicast traffic to all slave ports when there is no MLD join receive. | 3.7.11-3.7.14 | |
| CM-29259 | You might see the following gport error messages in switchd.log:
These messages are harmless and can be ignored. | 3.7.12-3.7.14 | |
| CM-29165 | With FRR or OSPF, you might see an inconsistent link-state advertisement. For example, when you configure the OSPF default originate route as metric-type 1 with a specific metric, Cumulus Linux shows the default originate route as an external metric-type 2 route with the default metric in the database. This issue typically occurs when both IPv4 and IPv6 default routes exist in the routing table. | 3.7.12-3.7.14 | |
| CM-29148 | On MLX switches that contain an OSPF IP unnumbered neighborship with a high scale of prefixes being learned, a link flap might cause the neighbor entry to not be programmed in hardware. | 3.7.11-3.7.14 | |
| CM-29068 | On the Broadcom switch with the Trident3 ASIC, packet priority remark values assigned from each internal CoS value continue to work with default values; if you change the internal CoS value, the change does not take effect. | 3.7.11-3.7.14 | |
| CM-29043 | When a multipath route that contains an EVPN path exists together with an IPv4 BGP path in the VRF, the RMAC to VTEP binding is incorrect. This invalid entry occurs because Cumulus Linux treats IPv4 routes received over the eBGP IPv4 peering incorrectly in the VRF. To work around this issue, remove the unnecessary eBGP IPv4 peering. | 3.7.12-3.7.14 | |
| CM-29035 | When you upgrade Cumulus Linux on the EdgeCore AS7726-32X or AS7326-56X switch, you might see firmware errors similar to the following:W: Possible missing firmware /lib/firmware/tigon/tg3_tso5.bin for module tg3 You can safely ignore these error messages. | 3.7.12-3.7.14 | |
| CM-28944 | A change in a route map prefix list that should remove a route might not be reflected in the ospf6 database or in peers, and the route might not be deleted.To work around this issue, reenter the redistribute <connected\|static> route-map <route-map-name> statement in the configuration. | 3.6.2-3.7.14 | |
| CM-28940 | If you configure aggregate-address <address> summary-only before a component of the same aggregate is injected into the BGP table with the network or redistribute command, when you remove the aggregate-address configuration, the component stays suppressed; it is not advertised to peers. For example:Existing configuration: router bgp 1 If you add network 50.0.0.1/32, you see the following (expected) BGP table entries:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, Removing aggregate-address 50.0.0.0/8 summary-only at this point results in the following (unexpected) BGP table entry:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, To work around this issue, remove, then re-add the component prefix routes. | 3.7.12-3.7.14 | |
| CM-28932 | After you add a new VNI and a layer 3 SVI to a set of leafs, certain leafs might not be able to communicate on the layer 3 VNI. To work around this issue, reboot the leaf switch or restart switchd. | 3.7.6-3.7.13 | 3.7.14 |
| CM-28816 | The following security advisory has been announced for bash: CVE-2019-18276 Qualys scan QID 372268 setuid vulnerability When bash or bash scripts are run setuid, bash is supposed to drop privileges, but does so incorrectly, so that an attacker with command access to the shell can use enable -f for runtime loading of a new builtin that calls setuid() to regain dropped privileges.To work around this issue, do not make bash or bash scripts setuid. | 3.0.0-3.7.14 | |
| CM-28754 | On switches with the Trident2+ ASIC, adding SPAN rules disables PBR rules. | 3.7.3-3.7.14 | |
| CM-28613 | In EVPN Active-Active (MLAG) environments, rebooting one member of an MLAG pair should result in the local MAC mobility sequence number reverting to 0. Sometimes a reboot of one MLAG peer results in the local MAC mobility sequence number being set to a non-zero value despite that no more mobility events occur. This issue is cosmetic only, as BGP does not advertise the incorrect sequence number and forwarding entries correctly point to the remote VTEP where the MAC is now located. | 3.7.12-3.7.14 | |
| CM-28611 | In an EVPN Active-Active (MLAG) environment, sometimes a local-to-remote MAC mobility event results in the local sequence number appearing higher than the remote sequence number in zebra. This issue is cosmetic only, as BGP does not advertise the incorrect sequence number and forwarding entries correctly point to the remote VTEP where the MAC is now located. | 3.7.12-3.7.14 | |
| CM-28596 | On the Dell Z9100 switch, 100G-SR4 modules might not link up reliably in certain ports. swp1, 2, 3, 9, 10, 23, 24, 30, 31, and 32 might be affected To work around this issue, move 100G SR4 modules to one of the ports not affected by this issue. | 3.7.11-3.7.14 | |
| CM-28533 | On the Lenovo NE0152T switch, one power supply (PSU2) always show as ABSENT in smonctl. | 3.7.11-3.7.14 | |
| CM-28465 | When you try to configure link-down on a parent interface of a subinterface configured in a VRF, you encounter an error. | 3.7.11-3.7.14 | |
| CM-28462 | On rare occasions, when you upgrade Cumulus Linux with the apt-get upgrade command, the upgrade fails and reports No space left on device. Checking the disk utilization shows that the disk is not full.To work around this issue, run the apt-get upgrade command again and reboot the device if prompted to complete the upgrade. | 3.7.10-3.7.14 | |
| CM-28451 | An error similar to the following shows in syslog for Mellanox switches:2020-02-12T19:59:22.208012+08:00 leaf01 sx_sdk: RM_TABLE: No resources available to add 1 entries to KVD hash Table HW resource To work around this issue, reboot the switch. | 3.7.11-3.7.13 | 3.7.14 |
| CM-28442 | PTM mis-detects incorrect hostnames of LLDP neighbors and does not fail them as expected. Instead they end up in an N/A cabling status. | 3.7.11-3.7.13 | 3.7.14 |

| CM-28393 | On the Dell S5232F-ON switch, EVPN and dynamic VRF route leaking results in the CPU forwarding traffic to newly-learned type-2 routes. To work around this issue, restart FRR. | 3.7.9-3.7.14 | |
| CM-28372 | On the EdgeCore AS7326-56X switch, the default fan speed, which is defined in the thermal specification, results in excessive fan noise. | 3.7.11-3.7.14 | |
| CM-28219 | The following vulnerability affects sudo, which is installed by default on Cumulus Linux. It is potentially exploitable on Cumulus Linux if pwfeedback (which is NOT enabled by default) is enabled in the /etc/sudoers file. CVE-2019-18634: In Sudo before 1.8.26, if pwfeedback is enabled in /etc/sudoers, users can trigger a stack-based buffer overflow in the privileged sudo process. The attacker needs to deliver a long string to the stdin of getln() in tgetpass.c.

| CM-28136 | The MLAG switch pair has VLANs defined that are not used on MLAG bonds. These VLANs still synchronize MAC addresses across to the peer switch. This results in log messages that indicate a MAC address is installed and the VLAN is not defined; for example:RTM_NEWNEIGH with unconfigured vlan XXXX on port peerlink | 3.7.10-3.7.13 | 3.7.14 |
| CM-28080 | TACACS+ through ClearPass is not currently supported. Cumulus Linux sends authorization before authentication, but ClearPass does not accept an authorization before the user is authenticated. | 3.7.11-3.7.14 | |
| CM-28078 | On the Broadcom switch with the Trident3 ASC, packet priority remark values assigned from each internal CoS value continue to work with default values; if you change the internal CoS value, the change does not take effect. | 3.7.11-3.7.14 | |
| CM-28076 | After you hot swap a PSU, the decode-syseeprom -t psuX command shows the old PSU information (such as the serial number), until you run the decode-syseeprom --init command. | 3.6.0-3.7.14 | |
| CM-28061 | On switches with the Trident3 ASIC, PFC is not working as expected. If you set the PFC for only one CoS, pause frames are sent for all CoS traffic. | 3.7.11-3.7.14 | |
| CM-28003 | The FRR service does not provide a way for automation to know if the configuration applied properly. To work around this issue, execute the vtysh -f <file> command in the automation file before starting the FRR service to validate the functional configuration and return an error code. | 3.7.11-3.7.14 | |
| CM-27957 | If you have configured a higher number of ports and VLANs (ports x VLANs) or the switch is a lower-powered (CPU) platform, the switchd service might fail to send a systemd keepalive within the watchdog timeout value (2 minutes by default) and you see an error similar to the following:bq. systemd[1]: switchd.service watchdog timeout (limit 2min)! To workaround this issue, either reduce the number of configured interfaces and, or VLANs, or increase the systemd timeout for switchd.service.To increase the systemd timeout:

| CM-27793 | A security vulnerability has been announced in the cyrus-sasl2 (libsasl2-2 and libsasl2-modules) package. The libraries are installed by default on Cumulus Linux. CVE-2019-19906: Stephan Zeisberg reported an out-of-bounds write vulnerability in the _sasl_add_string() function in cyrus-sasl2, a library implementing the Simple Authentication and Security Layer. A remote attacker can take advantage of this issue to cause denial-of-service conditions for applications using the library. Vulnerable: 2.1.27+dfsg-1 Fixed: 2.1.27+dfsg-1+deb10u1 | 3.0.0-3.7.14 | |
| CM-27698 | SNMP ifLastChange reports link transitions when there are none. | 3.7.6-3.7.14 | |
| CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior:
| 3.7.11-3.7.14 | |
| CM-27581 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.14 | |
| CM-27530 | When hal.bcm.per_vlan_router_mac_lookup is set to TRUE in the /etc/cumulus/switchd.conf file, inter-VLAN traffic is forwarded to the CPU when associated VNI interfaces exist. | 3.7.10-3.7.14 | |
| CM-27522 | The NCLU command net show interface produces an error if bonds with no members exist.To work around this issue, remove the empty Bond interfaces from the /etc/network/interfaces file and run sudo ifreload -a. | 3.7.10-3.7.14 | |
| CM-27489 | Mellanox switches might experience higher CPU usage from the sx_sdk service or when BFD is in use.To work around this issue, disable BFD to alleviate some of the CPU load. | 3.7.13 | 3.7.14 |
| CM-27354 | On the Celestica Pebble switch, if you use IPv6 routes with mask /65 to /127, the switchd log fills with errors. | 3.7.10-3.7.13 | 3.7.14 |
| CM-27279 | When ECMP routes have both VXLAN (symmetric routing) and non-VXLAN paths, the non-VXLAN path is incorrectly installed in the RIB and FIB to point across VXLAN. The non-VXLAN next-hop will be installed as an offload entry in the neighbor table (ip neigh show) with a mac address of 00:00:00:00:00:00. | 3.7.3-3.7.14 | |
| CM-27192 | If you use NCLU commands to add a non-MLAG bond, then add an MLAG configuration, the net commit command fails. However, a subsequent net commit command succeeds. | 3.7.10-3.7.14 | |
| CM-27173 | On the Trident3 switch, unicast ARP packets received on a VNI and forwarded to the CPU are not policed. | 3.7.10-3.7.13 | 3.7.14 |
| CM-27094 | On the Delta AG9032v1 switch, smonctl and sensors report inaccurate PSU current and power. | 3.5.0-3.7.14 | |
| CM-27018 | If you configure more than one VRR interface on an SVI interface, deleting one of the VRR addresses does not remove the interface/address. | 3.7.10-3.7.14 | |
| CM-26921 | If you delete an undefined bond, then add a bond slave, the net commit command fails. | 3.7.9-3.7.14 | |
| CM-26913 | FRR configuration commands for an SVI interface might have the \n misplaced in the output. For example:sudo sh -c “printf ‘interface 50\nvrf TEST description L3 routing interface\n’ » /etc/frr/frr.conf" should be: sudo sh -c “printf ‘interface 50 vrf TEST\ndescription L3 routing interface\n’ » /etc/frr/frr.conf" To work around this issue, configure the interface manually in the /etc/frr/frr.conf file. | 3.7.9-3.7.14 | |
| CM-26905 | When you update the hostname of a switch with the NCLU net add hostname <hostname> command, then run net commit, the lldpd service does not restart and other devices still see the old hostname.To work around this issue, run the sudo systemctl restart lldpd.service command. | 3.7.10-3.7.14 | |
| CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-3.7.14 | |
| CM-26655 | If you reconfigure an NTP server with NCLU using different trailing options after the IP address (such as iburst), an invalid configuration is added to the /etc/ntp.conf file. For example:net add time ntp server 1.2.3.4 iburst If you need to alter existing server configurations, first remove the server, commit, then re-add the server with any trailing options. | 3.7.9-3.7.14 | |
| CM-26599 | Auto-negotiation does not work with the QSFP28 cables and a remote system operating at 10G. Attempting to enable auto-negotiation with ethtool -s swp<#> autoneg on returns Operation not supported.To work around this issue, do not use auto-negotiation and set the local port speed to 10G. | 3.7.9-3.7.14 | |
| CM-26595 | The NCLU net show lldp command displays the speed of a ganged port group as the speed of one of the individual links, rather than the sum of their speeds. | 3.7.9-3.7.14 | |
| CM-26516 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.14 | |
| CM-26463 | The following CVEs affect the linux kernel package: CVE-2019-14821 CVE-2019-14835 CVE-2019-15117 CVE-2019-15118 CVE-2019-15902 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | 3.7.10-3.7.14 | |
| CM-26423 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.14 | |
| CM-26412 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.14 | |
| CM-26288 | On the Mellanox switch, static VXLAN tunnels incorrectly allow traffic from any remote tunnel IP address. | 3.7.8-3.7.14 | |
| CM-26256 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.14 | |
| CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.14 | |
| CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:-A FORWARD -i vni10 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.14 | |
| CM-26136 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.14 | |
| CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.14 | |
| CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-3.7.14 | |
| CM-25890 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.14 | |
| CM-25859 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.14 | |
| CM-25815 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.14 | |
| CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:ifdown vlan123 ; sleep 2 ; ifup vlan123 You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.14 | |
| CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.14 | |
| CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-3.7.14 | |
| CM-25740 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:cumulus@switch:~$ net add bridge mybridge vlan-protocol 802.1ad | 3.7.6-3.7.14 | |
| CM-25694 | If a packet is policed by ebtables, it does not increment an ACL drop on the ingress interface. Instead, it increments the TDBGC3/6 drop counter to the CPU. | 3.7.6-3.7.14 | |
| CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.14 | |
| CM-25400 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.14 | |
| CM-25397 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.14 | |
| CM-25001 | The following CVEs were announced in Debian Security Advisory DSA-444-1, DSA-4447-1 and affect the linux kernel and microcode. Package: linux CVE ID: CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091 Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. Contact your hardware ndor for microcode uppdates. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver. Fixed in version 4.19.76-1+cl4u1 | 3.0.0-3.7.14 | |
| CM-24894 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.14 | |
| CM-24799 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.14 | |
| CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-3.7.14 | |
| CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.14 | |
| CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.14 | |
| CM-24652 | In an EVPN environment, the centralized MAC address is not installed on the MLAG pair because Cumulus Linux does not perform an SVI MAC check per VLAN. This issue does not affect a pure distributed routing (symmetric or asymmetric) environment or a pure centralized routing environment. | 3.7.0-3.7.14 | |
| CM-24618 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:ERROR: No closing quotation See /var/log/netd.log for more details. | 3.6.1-3.7.14 | |
| CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.14 | |
| CM-24435 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect: net add routing route-map Proxy-ARP permit 25 match interface swp9-10 These commands are correct: net add routing route-map Proxy-ARP permit 25 match interface swp9 net add routing route-map Proxy-ARP permit 30 match interface swp10 | 3.7.2-3.7.14 | |
| CM-24426 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf <name> command just displays
Tab completion for the net add vrf <name> ip address <address> command works correctly. | 3.7.4-3.7.14 | |
| CM-24379 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.14 | |
| CM-24343 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.14 | |
| CM-24332 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.14 | |
| CM-24272 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface br0.100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# vrrp 1 advertisement-interval switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24271 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface vlan100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24270 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface swp4 switch(config-if)# vrrp 1 version 2 switch(config-if)# no vrrp 1 preempt switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24262 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto <iface> lines exist. | 3.7.3-3.7.14 | |
| CM-24241 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:cumulus@switch:~$ net del bgp neighbor fabric peer-group ‘router bgp 65001’ configuration does not have ‘neighbor fabric peer-group’ | 3.7.2-3.7.14 | |
| CM-24222 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.14 | |
| CM-24035 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.14 | |
| CM-23825 | The net add interface <interface> ptm-enable command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.14 | |
| CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev <interface> command. | 3.7.0-3.7.14 | |
| CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.14 | |
| CM-23665 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan <layer3-vni> bridge access <vlan>. This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.14 | |
| CM-23661 | On the Mellanox switch, when you configure a GRE tunnel, the traffic behind the local tunnel endpoint destined through the GRE tunnel is software-forwarded. | 3.7.2-3.7.14 | |
| CM-23651 | In an EVPN symmetric routing configuration, when an IP address is frozen, kernel neighbor table information and kernel VRF routing table information about the frozen IP address might be out-of-sync. | 3.7.3-3.7.14 | |
| CM-23584 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.14 | |
| CM-23570 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.14 | |
| CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.14 | |
| CM-23418 | For QSFP modules, the sudo ifdown command does not disable the Tx laser. | 3.7.2-3.7.14 | |
| CM-23417 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.14 | |
| CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.6.2-3.7.14 | |
| CM-23125 | The OpenSSL package on Cumulus Linux 3.x has a vulnerability similar to CVE-2018-0734. (The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key). According to Debian upstream, this version “is not vulnerable [to CVE-2018-0734 exactly]. Nevertheless, there is a bug fix that futher reduces the amount of leaked timing information. It got no CVE on its own and introduced this vulnerability.“ Vulnerable on CL3: 1.0.1t-1+deb8u12 | 3.0.0-3.7.14 | |
| CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.14 | |
| CM-23075 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:2018-11-10T23:35:30.992370-08:00 Dev dhcrelay: Listening on LPF/vlan.101/a0:00:00:00:00:51 2018-11-10T23:35:30.993472-08:00 Dev dhcrelay: Sending on LPF/vlan.101/a0:00:00:00:00:51 Eventually the dhcrelay service stops. | 3.7.1-3.7.14 | |
| CM-23021 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.14 | |
| CM-23004 | The local fallback account authenticates using the local password when the RADIUS or TACACS service is up. The expected behavior is for this to fail and only succeed when the RADIUS OR TACACS server fails to respond. | 3.7.1-3.7.14 | |
| CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.6.0-3.7.14 | |
| CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.14 | |
| CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.5.2-3.7.14 | |
| CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.6.2-3.7.14 | |
| CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.6.0-3.7.14 | |
| CM-22554 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 3.6.2-3.7.14 | |
| CM-22386 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.14 | |
| CM-22301 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.A $INGRESS_CHAIN –in-interface $INGRESS_INTF -m addrtype –dst-type IPROUTER -j POLICE –set-mode pkt –set-rate 400 –set-burst 100 These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 3.6.1-3.7.14 | |
| CM-22287 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 3.6.2-3.7.14 | |
| CM-22274 | To ease interoperation with non-Cumulus devices, it is possible to configure the route-target import and export values under the layer 2 VNI EVPN configuration. The same configuration does not work for both layer 2 VNI and layer 3 VNIs. Set the EVPN address-family within the VNI context when configuring the route-target in the layer 2 VNI. Set the EVPN address-family without the VNI context when configuring the route-target in the layer 3 VNI. | 3.6.0-3.7.14 | |
| CM-22252 | On the Edgecore OMP-800, there is no Power Supply information from the sensor or from smonctl. The platform driver has support for the PSUs but this was not added to the sensors infrastructure.This is a known limitation on the OMP-800 platform. | 3.6.2-3.7.14 | |
| CM-22228 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.14 | |
| CM-22205 | If a user is in vtysh when FRR is restarted, the running configuration in that vtysh session shows empty. | 3.6.2-3.7.14 | |
| CM-22138 | When you run the NCLU net show system command or the NetQ netq inventory command on the Edgecore OMP-800 switch, the output does not show any port or chip information. | 3.6.2-3.7.14 | |
| CM-22041 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.4.3-3.7.14 | |
| CM-22020 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.14 | |
| CM-21785 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 3.6.2-3.7.14 | |
| CM-21769 | On the Mellanox switch, GRE tunneling does not work if the tunnel source is configured on an SVI interface. If the tunnel source is configured on a physical switch port, then tunneling works as expected. | 3.6.1-3.7.13 | 3.7.14 |
| CM-21678 | On a Dell switch with a Maverick ASIC, NetQ might receive false alerts like the following via PagerDuty: cumulus@switch:~$ netq show sensors temp changes | grep absent | grep -v psu P2Leaf01 temp9 networking asic die temp sensor absent 43 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 47 105 100 5 Unable to read temp4_highest Add 9d:23h:26m:6s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to read temp4_highest Add 14d:22h:46m:45s This message might occur as a result of a timeout at the hardware level, or the switch might be reporting a failure to get a response. | 3.5.3-3.7.14 | |
| CM-21667 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 3.6.1-3.7.14 | |
| CM-21379 | If a primary route becomes unavailable (for example, you run ifdown on the switch port), the backup route remains inactive and is not installed into FIB.To work around this issue, configure routes as ECMP: cumulus@switch:~$ net del routing route 4.1.1.0/24 1.1.1.1 10 cumulus@switch:~$ net add routing route 4.1.1.0/24 1.1.1.1 cumulus@switch:~$ net commit | 3.5.3-3.7.14 | |
| CM-21332 | When two VLAN subinterfaces are bridged to each other in a traditional mode bridge, switchd doesn’t assign a gport to the subinterface, even though a gport is expected for each VLAN subinterface.To work around this issue, you can do one of two things:
| 3.5.3-3.7.14 | |
| CM-21058 | The advertised routes list may be empty for an EVPN peering even though the remote switch reports received routes. | 3.6.0-3.7.14 | |
| CM-21055 | On the Mellanox switch, the destination MAC address of ERSPAN GRE packets is set to all zeros; therefore, the first transit switch might drop packets. | 3.6.0-3.7.13 | 3.7.14 |
| CM-20813 | Span rules matching the out-interface as a bond do not mirror packets. | 3.6.0-3.7.14 | |
| CM-20693 | In NCLU, you can only set the community number in a route map. You cannot set other community options such as no-export, no-advertise, or additive.This is a known limitation in network-docopt and is documented in the Cumulus Linux user guide. | 3.5.1-3.7.14 | |
| CM-20508 | The Cumulus-Resource-Query-MIB defines the ability to gather buffer utilization status but when these objects are polled, they return nothing. | 3.5.3-3.7.14 | |
| CM-20480 | The python-crypto package, which is not installed by default on Cumulus Linux, but is present in the repository to be installed, has the following security vulnerability in the version available for Cumulus Linux 3.x: CVE-2018-6594: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto’s ElGamal implementation. More information at https://security-tracker.debian.org/tracker/CVE-2018-6594 . | 3.0.0-3.7.14 | |
| CM-20033 | The VLAN interface stays up even though the physical link carrying the VLAN is admin or carrier down. | 3.5.2-3.7.14 | |
| CM-19788 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.5.0-3.7.14 | |
| CM-19724 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 3.5.2-3.7.14 | |
| CM-19454 | When you use NCLU to bring a bond admin down (net add bond <bond> link down), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown <bondname> command. | 3.5.0-3.7.14 | |
| CM-19006 | On the Broadcom Trident II+, Trident 3, and Maverick based switch, in an external VXLAN routing environment, when a lookup is done on the external-facing switch (exit/border leaf) after VXLAN decapsulation, the switch does not rewrite the MAC addresses and TTL; for through traffic, packets are dropped by the next hop instead of correctly routing from a VXLAN overlay network into a non-VXLAN external network (for example, to the Internet). This applies to all forms of VXLAN routing (centralized, asymmetric and symmetric) and affects all traffic from VXLAN overlay hosts that need to be routed after VXLAN decapsulation on an exit/border leaf, including:
For example, if the expected interface configuration is: auto swp3.2001 iface swp3.2001 vrf vrf1 address 45.0.0.2/24 # where swp3 is the external facing port and swp3.2001 is the VLAN subinterface auto bridge iface bridge bridge-vlan-aware yes bridge ports vx-4001 bridge-vids 4001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 Modify the configuration as follows: auto swp3 iface swp3 bridge-access 2001 # associate the port (swp3) with bridge 2001 auto bridge iface bridge bridge-vlan-aware yes bridge ports swp3 vx-4001 vx-16000000 bridge-vids 4001 2001 # where vx-4001 is the existing VNI and vx-16000000 is a new temporary VNI # this is now bridging the port (swp3), the VNI (vx-4001), # and the new temporary VNI (vx-16000000) # the bridge VLAN IDs are now 4001 and 2001 auto vlan2001 iface vlan2001 vlan-id 2001 vrf vrf1 address 45.0.0.2/24 vlan-raw-device bridge # create a VLAN 2001 with the associated VRF and IP address auto vx-16000000 iface vx-16000000 vxlan-id 16000000 bridge-access 2001 <… usual vxlan config …> # associate the temporary VNI (vx-16000000) with bridge 2001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 If an MLAG pair is used instead of a single exit/border leaf, the same temporary VNIs should be added on both switches of the MLAG pair. on the Broadcom Trident 3 switch. Note: This issue still exists on the Broadcom Trident II+ and Maverick-based switch. | 3.5.0-3.7.14 | |
| CM-18192 | In FRR, bgp_snmp does not show all BGP peers when peer groups used. | 3.7.11-3.7.14 | |
| CM-17934 | FRR tracks interface speed based on the value it learns from the Linux kernel for that interface. If the interface speed changes, FRR does not update its interface speed cache. This can lead to issues for routing protocols that derive metrics from interface speed as the cost can become out of sync with the interface speed. To work around this issue, manually define the routing protocol metric for these interfaces or restart FRR. | 3.7.6-3.7.14 | |
| CM-17557 | When sFlow is enabled, some sampled packets, such as IPMC, are forwarded twice (in the ASIC and then again through the kernel networking stack). | 3.4.0-3.7.14 | |
| CM-17494 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See Address Resolution Protocol in the Cumulus Linux user guide for more information. | 3.3.2-3.7.14 | |
| CM-16855 | If a two nodes on both sides of a link change from auto-negotiation off to auto-negotiation on for both sides during a short interval (around one second), the link might start flapping or stay down.To work around this issue and stop the flapping, turn the link down on the switch with the command ifdown swpX, wait a few seconds, then bring the link back up with the command ifup swpX. Repeat this on the other side if necessary. | 3.3.2-3.7.14 | |
| CM-16571 | NCLU cannot manage rsyslog to addresses routed via a VRF. In Cumulus Linux 4.0.0 and later, management VRF is enabled by default. To work around this issue, update the /etc/network/interfaces file to disable management VRF. | 3.4.3-3.7.14 | |
| CM-16461 | After booting a Cumulus VX virtual machine running the VMware OVA image, sometimes messages from sensors appear, indicating that the “Avg state” is critical, with all values displayed as 100.0. A cl-support is generated. | 3.4.2-3.7.14 | |
| CM-15812 | Multicast forwarding fails for IP addresses whose DMAC overlaps with reserved DIPs. | 3.2.1-3.7.14 | |
| CM-15601 | On a Mellanox switch in an MLAG configuration, routed packets that arrive on one switch to be forwarded to a destination MAC across the peer link are dropped due to MLAG loop prevention. This affects both routed unicast and multicast packets.To work around this issue, modify the routing design or policy such that routes do not have a next hop of an MLAG peer switch that traverses the MLAG peer link. | 3.6.2-3.7.13 | 3.7.14 |
| CM-15094 | Counter samples for an 80G bond (2 x 40G) exported from the switch show an interface speed (ifSpeed) of 14.464Gbps. | 3.2.0-3.7.14 |
Fixed Issues in 3.7.13
| Issue ID | Description | Affects |
|---|---|---|
| CM-30818 | The following vulnerabilities have been announced in librsvg, which is available in the repository for optional installation:CVE-2016-6163: The rsvg_pattern_fix_fallback function in rsvg-paint_server.c in librsvg2 2.40.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted svg file. CVE-2019-20446: In xml.rs in GNOME librsvg before 2.46.2, a crafted SVG file with nested patterns can cause denial of service when passed to the library for processing. The attacker constructs pattern elements so that the number of final rendered objects grows exponentially. Vulnerable: <= 2.40.5-1+deb8u2 Fixed: 2.40.5-1+deb8u3 | 3.0.0-3.7.12 |
| CM-30582 | The following vulnerability has been announced in glib-networking, which is not installed by default, but is available in the repository for optional installation. CVE-2020-13645: In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server’s TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification. Vulnerable: 2.42.0-2 Fixed: 2.42.0-2+deb8u1 | 3.0.0-3.7.12 |
| CM-30581 | The following vulnerabilities have been announced in NGINX, which is installed by default on Cumulus Linux (however, the default nginx configuration is not vulnerable, since it does not configure error_page redirection or use lua): CVE-2019-20372: NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer. CVE-2020-11724: An issue was discovered in OpenResty before 1.15.8.4. ngx_http_lua_subrequest.c allows HTTP request smuggling, as demonstrated by the ngx.location.capture API. Vulnerable: <= 1.6.2-5+deb8u6 Fixed: 1.6.2-5+deb8u7 | 3.0.0-3.7.12 |
| CM-30533 | CVE-2020-15389: jp2/opj_decompress.c in OpenJPEG through 2.3.1 has a use-after-free that can be triggered if there is a mix of valid and invalid files in a directory operated on by the decompressor. Triggering a double-free may also be possible. This is related to calling opj_image_destroy twice. Vulnerable: <= 2.1.0-2+deb8u10 Fixed: 2.1.0-2+deb8u11 | 3.0.0-3.7.12 |
| CM-30532 | Several issues were discovered in Python 3.4, an interactive high-level object-oriented language, that allow an attacker to cause denial of service, trafic redirection, header injection and cross-site scripting. CVE-2013-1753: The gzip_decode function in the xmlrpc client library allows remote attackers to cause a denial of service (memory consumption) via a crafted HTTP request. CVE-2016-1000110:The CGIHandler class does not protect against the HTTP_PROXY variable name clash in a CGI script, which could allow a remote attacker to redirect HTTP requests. CVE-2019-16935:The documentation XML-RPC server has XSS via the server_title field. This occurs in Lib/xmlrpc/server.py. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server. CVE-2019-18348: In urllib2, CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n (specifically in the host component of a URL) followed by an HTTP header. CVE-2020-8492: Python allows an HTTP server to conduct Regular Expression Denial of Service (ReDoS) attacks against a client because of urllib.request.AbstractBasicAuthHandler catastrophic backtracking. CVE-2020-14422: Lib/ipaddress.py improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. Vulnerable: <= 3.4.2-1+deb8u7 Fixed: 3.4.2-1+deb8u8 | 3.0.0-3.7.12 |
| CM-30531 | Several vulnerabilities where found in Perl’s regular expression compiler. An application that compiles untrusted regular expressions could be exploited to cause denial of service or code injection. It is discouraged to allow untrusted regular expressions to be compiled by Perl.

| CM-29044 | A large number of flapping peers causes FRR to require a corresponding update to internal data structures that track peer information. Updating this internal data structure does not delete links that are down due to the flapping. The size of this array then grows to contain both current peers as well as peers that should have been deleted during the flap processing. The contents of this array is processed by FRR to poll the links, which consumes CPU for all items in the array. This additional polling consumes more CPU than necessary but has no functional impact. To work around this issue, restart FRR. | 3.7.11-3.7.12 |

| CM-28995 | After you flap an MLAG peerlink, a rare condition might occur where routes and neighbors for VXLAN-enabled VLANs are misprogrammed as non-VXLAN routes and neighbors due to VNI state transitions. This results in a forwarding failure for traffic destined to these misprogrammed routes and neighbors. Note: Do not flap a VNI interface manually. The only expected time for a VNI interface to go down is when the MLAG secondary switch brings the VNIs protodown during a peer link failure where the backup IP address is still active. To recover from this condition, restart switchd with the sudo systemctl restart switchd command. | 3.7.10-3.7.12 |

| CM-27586 | CPU usage might be higher than normal if you have a high number of interfaces x VLANs and lldpd is active. This issue is introduced with code changes in Cumulus Linux 3.7.11, where VLAN information is now available for LLDP to advertise to neighbors (https://docs.cumulusnetworks.com/version/cumulus-linux-37/Layer-2/Link-Layer-Discovery-Protocol/#vlan-dot1-tlv). You might see high CPU usage even if VLAN (dot1) TLV configuration is disabled.To check if lldpd is the heavy CPU resource user, run the following command:cumulus@switch:~$ ps -eo user,pid,ppid,cmd,%mem,%cpu –sort=-%cpu | head Alternatively, check for messages in the /var/log/syslog directory similar to:2020-02-20T15:02:12.137857-05:00 leaf01 sysmonitor: High CPU use: 87% Note: The exact amount of CPU usage varies in each network based on a number of factors; however, it is unusual for lldpd to consume more than 30% CPU for an extended period of time.To work around this issue, you can do one of the following:
| 3.7.11-3.7.12 |
| CM-26225 | On the EdgeCore AS5712, AS6712, AS5812 and AS6812 switch, support for multiple PSU types results in log messages similar to the following:2019-09-05T05:15:17.246597+00:00 hp-6712-03 decode-syseeprom: Unable to find eeprom at /sys/bus/i2c/devices/11-0050/eeprom for psu2 | 3.7.9-3.7.12 |

| CM-33012 | After you add an interface to the bridge, an OSPF session flap can occur. | 3.7.9-3.7.14 | |
| CM-33008 | Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed. CVE-2020-19667 Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c CVE-2020-25665 The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. This could cause impact to reliability. CVE-2020-25674 WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. CVE-2020-27560 ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service. CVE-2020-27750 A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould trigger undefined behavior in the form of values outside the range of type unsigned char and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27760 In GammaImage() of /MagickCore/enhance.c, depending on the gamma value, it’s possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. CVE-2020-27763 A flaw was found in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27765 A flaw was found in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27773 A flaw was found in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-29599 ImageMagick mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.

| CM-32275 | After you reboot a Broadcom switch, switchd might fail to restart and you see logs in switchd.log similar to the following:… | 3.7.11-3.7.14 | |
| CM-32226 | If switchd successfully signals clagd that it is going down, clagd stops responding to keepalive echo requests from the peer instead of sending a good bye to the peer over both the peerlink and the backup switch. Eventually, the keepalive timer expires and the secondary switch becomes the primary, and brings the bonds and VNIs back up. However, if switchd does not successfully signal it is going down, (in the event of a crash), the primary switch continues to respond to keepalives, and the bonds and VNIs are down on both peers. | 3.7.12-3.7.14 | |
| CM-32225 | A slow memory leak is observed (1% per 14 hours) in kmalloc-256. To work around this issue, reboot the switch. | 3.7.12-3.7.14 | |

| CM-30863 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.0.0-3.7.14 | |
| CM-30858 | A vulnerability was found in curl, a command line tool for transferring data with URL syntax. curl is installed by default on Cumulus Linux.CVE-2020-8177: When using when using -J (–remote-header-name) and -i (–include) in the same command line, a malicious server could force curl to overwrite the contents of local files with incoming HTTP headers.

| CM-29872 | Tab completion for the net show rollback description command returns information about a snapshot instead of context help.To work around this issue, run the net show commit history command to find descriptions instead of the net show rollback description command. | 3.7.12-3.7.14 | |
| CM-29871 | The net show rollback description <string> command returns an error even if the string matches a commit description.To work around this issue, look for your string in the output of the net show commit history command (or grep for it there) instead. | 3.7.12-3.7.14 | |
| CM-29838 | CPU utilization may increase when clag-managed bond interfaces are operationally/LACP down but the physical carrier remains up on the bond member switchports. This condition occurs when clag bond redirection is enabled and bond members remain up while the parent bond does not negotiate LACP.This issue is resolved in Cumulus Linux 3.7.14. | 3.7.9-3.7.13 | 3.7.14 |

| CM-29830 | Unicast traffic from downlink hosts is flooded to multiple remote VTEPs, which might also cause high HwIfOutQDrops/TX_DRP on the uplink ports. To work around this issue, restart switchd. | 3.7.10-3.7.13 | 3.7.14 |
| CM-29807 | After a neighbor is removed, the redistributed neighbor entry is withdrawn from the BGP table, but the prefix might still be selected as the bestpath when the host’s originated prefix is not advertised. To work around this issue, recreate the neighbor entry and flap the interface to the host. Or, if the host is already down, manually create a neighbor entry with an invalid MAC address, which forces redistribute neighbor to re-withdraw the entry. | 3.7.3-3.7.12 | 3.7.13-3.7.14 |
| CM-29779 | In LLDP, the snmp subagent loses all subsequent lldpRemSysName (1.0.8802.1.1.2.1.4.1.1.9) entries after an entry with a missing SysName is added.All the information from lldpctl is correct. Only the entries after the entry that is missing a SysName in lldpRemSysName disappear from the snmp subagent. | 3.7.12-3.7.14 | |
| CM-29778 | If packets with an invalid checksum are received, the cumulus-poe service might restart and you see log messages similar to the following:May 20 10:48:04.665635 leaf01 poed[8012]: ERROR : invalid checksum in response [0xC2:0x00] May 20 10:48:04.671299 leaf01 poed[8012]: poed : ERROR : invalid checksum in response [0xC2:0x00] May 20 10:48:04.708620 leaf01 systemd[1]: cumulus-poe.service: main process exited, code=exited, status=1/FAILURE The service starts automatically but there is an impact to POE devices momentarily. | 3.7.12 | 3.7.13-3.7.14 |

| CM-29556 | The following vulnerability has been announced that affects ntp: CVE-2020-11868: ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address, because transmissions are rescheduled even when a packet lacks a valid origin timestamp. This affects: ntp-4.2.8p12 (possibly earlier) and ntp-4.2.8p13 The fix for https://bugs.ntp.org/3445 introduced a bug whereby a system that is running ntp-4.2.8p12 or p13 that only has one unauthenticated time source can be attacked in a way that causes the victim’s next poll to its source to be delayed, for as long as the attack is maintained. http://support.ntp.org/bin/view/Main/NtpBug3592 gives the following mitigations if it is not possible to upgrade to a version with the fix:
| 3.0.0-3.7.14 | |
| CM-29546 | In vtysh, if you configure, then remove a layer 3 VNI for a VRF, the VNI is removed from zebra even if the VNI interface still exists in the kernel. If you configure a layer 2 VNI as a layer 3 VNI by mistake, removing the layer 3 VNI binding removes it from zebra but EVPN-learned MACs and neighbors are not installed into the kernel. To work around this issue, delete, then re-add the missing VNI. For example: cumulus@switch:~$ sudo ifdown vni10100 If you flap the link with the ip link set vni10100 down; ip link set vni10100 up commands, zebra does not re-add the VNI. | 3.7.12-3.7.14 | |

| CM-29284 | The following vulnerabilities affect git, which is available in the repository for optional installation: CVE-2020-5260: Felix Wilhelm of Google Project Zero discovered a flaw in git, a fast, scalable, distributed revision control system. With a crafted URL that contains a newline, the credential helper machinery can be fooled to return credential information for a wrong host. CVE-2020-11008: Carlo Arenas discovered a flaw in git, a fast, scalable, distributed revision control system. With a crafted URL that contains a newline or empty host, or lacks a scheme, the credential helper machinery can be fooled into providing credential information that is not appropriate for the protocol in use and host being contacted. | 3.0.0-3.7.12 | 3.7.13-3.7.14 |
| CM-29259 | You might see the following gport error messages in switchd.log:
These messages are harmless and can be ignored. | 3.7.12-3.7.14 | |
| CM-29208 | The following vulnerability has been announced in ceph; the associated libraries librados2 and librbd1 are available in the Cumulus Linux 3 repository for optional installation. CVE-2020-1760: It was discovered that there was a header-splitting vulnerability in ceph, a distributed storage and file system.

| CM-29165 | With FRR or OSPF, you might see an inconsistent link-state advertisement. For example, when you configure the OSPF default originate route as metric-type 1 with a specific metric, Cumulus Linux shows the default originate route as an external metric-type 2 route with the default metric in the database. This issue typically occurs when both IPv4 and IPv6 default routes exist in the routing table. | 3.7.12-3.7.14 | |
| CM-29148 | On MLX switches that contain an OSPF IP unnumbered neighborship with a high scale of prefixes being learned, a link flap might cause the neighbor entry to not be programmed in hardware. | 3.7.11-3.7.14 | |
| CM-29068 | On the Broadcom switch with the Trident3 ASIC, packet priority remark values assigned from each internal CoS value continue to work with default values; if you change the internal CoS value, the change does not take effect. | 3.7.11-3.7.14 | |
| CM-29048 | The following vulnerability exists in the ruby2.1 package: CVE-2016-2338: An exploitable heap overflow vulnerability exists in the Psych::Emitter startdocument function of Ruby. In Psych::Emitter startdocument function heap buffer “head” allocation is made based on tags array length. Specially constructed object passed as element of tags array can increase this array size after mentioned allocation and cause heap overflow Vulnerable: <= 2.1.5-2+deb8u8 Fixed: 2.1.5-2+deb8u9 | 3.0.0-3.7.12 | 3.7.13-3.7.14 |
| CM-29044 | A large number of flapping peers causes FRR to require a corresponding update to internal data structures that track peer information. Updating this internal data structure does not delete links that are down due to the flapping. The size of this array then grows to contain both current peers as well as peers that should have been deleted during the flap processing. The contents of this array is processed by FRR to poll the links, which consumes CPU for all items in the array. This additional polling consumes more CPU than necessary but has no functional impact. To work around this issue, restart FRR. | 3.7.11-3.7.12 | 3.7.13-3.7.14 |
| CM-29043 | When a multipath route that contains an EVPN path exists together with an IPv4 BGP path in the VRF, the RMAC to VTEP binding is incorrect. This invalid entry occurs because Cumulus Linux treats IPv4 routes received over the eBGP IPv4 peering incorrectly in the VRF. To work around this issue, remove the unnecessary eBGP IPv4 peering. | 3.7.12-3.7.14 | |
| CM-29040 | The following issue has been found in e2fsprogs, a package that contains ext2/ext3/ext4 file system utilities:CVE-2019-5188: A specially crafted ext4 directory can cause an out-of-bounds write on the stack, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. | 3.0.0-3.7.12 | 3.7.13-3.7.14 |
| CM-29037 | When a link flap occurs while IPv6 traffic traverses interfaces, a kernel panic may occur with the following logs printed to the console:[1675080.282051] BUG: unable to handle kernel NULL pointer dereference at 0000000000000110 | 3.7.12 | 3.7.13-3.7.14 |
| CM-29035 | When you upgrade Cumulus Linux on the EdgeCore AS7726-32X or AS7326-56X switch, you might see firmware errors similar to the following:W: Possible missing firmware /lib/firmware/tigon/tg3_tso5.bin for module tg3 You can safely ignore these error messages. | 3.7.12-3.7.14 | |
| CM-28995 | After you flap an MLAG peerlink, a rare condition might occur where routes and neighbors for VXLAN-enabled VLANs are misprogrammed as non-VXLAN routes and neighbors due to VNI state transitions. This results in a forwarding failure for traffic destined to these misprogrammed routes and neighbors. Note: Do not flap a VNI interface manually. The only expected time for a VNI interface to go down is when the MLAG secondary switch brings the VNIs protodown during a peer link failure where the backup IP address is still active. To recover from this condition, restart switchd with the sudo systemctl restart switchd command. | 3.7.10-3.7.12 | 3.7.13-3.7.14 |
| CM-28993 | The following security vulnerability has been announced that affects the libicu52 package: CVE-2020-10531: An issue was discovered in International Components for Unicode (ICU) for C/C++ through 66.1.

| CM-28954 | The python-twisted-* packages, which are available for optional installation in Cumulus Linux but are not installed by default, were found to have the following security vulnerabilities: CVE-2020-10808: In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request. CVE-2020-10809: In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request. | 3.0.0-3.7.12 | 3.7.13-3.7.14 |
| CM-28944 | A change in a route map prefix list that should remove a route might not be reflected in the ospf6 database or in peers, and the route might not be deleted.To work around this issue, reenter the redistribute <connected\|static> route-map <route-map-name> statement in the configuration. | 3.6.2-3.7.14 | |
| CM-28940 | If you configure aggregate-address <address> summary-only before a component of the same aggregate is injected into the BGP table with the network or redistribute command, when you remove the aggregate-address configuration, the component stays suppressed; it is not advertised to peers. For example:Existing configuration: router bgp 1 If you add network 50.0.0.1/32, you see the following (expected) BGP table entries:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, Removing aggregate-address 50.0.0.0/8 summary-only at this point results in the following (unexpected) BGP table entry:Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, To work around this issue, remove, then re-add the component prefix routes. | 3.7.12-3.7.14 | |
| CM-28932 | After you add a new VNI and a layer 3 SVI to a set of leafs, certain leafs might not be able to communicate on the layer 3 VNI. To work around this issue, reboot the leaf switch or restart switchd. | 3.7.6-3.7.13 | 3.7.14 |

| CM-28613 | In EVPN Active-Active (MLAG) environments, rebooting one member of an MLAG pair should result in the local MAC mobility sequence number reverting to 0. Sometimes a reboot of one MLAG peer results in the local MAC mobility sequence number being set to a non-zero value despite that no more mobility events occur. This issue is cosmetic only, as BGP does not advertise the incorrect sequence number and forwarding entries correctly point to the remote VTEP where the MAC is now located. | 3.7.12-3.7.14 | |
| CM-28611 | In an EVPN Active-Active (MLAG) environment, sometimes a local-to-remote MAC mobility event results in the local sequence number appearing higher than the remote sequence number in zebra.

| CM-28488 | The following CVEs were announced that affect the cron package. All of these require untrusted local user access.CVE-2017-9525 is a local user privilege escalation attack: In the cron package through 3.0pl1-128 on Debian, and through 3.0pl1-128ubuntu2 on Ubuntu, the postinst maintainer script allows for group-crontab-to-root privilege escalation via symlink attacks against unsafe usage of the chown and chmod programs. CVE-2019-9704, CVE-2019-9705, CVE-2019-9706 are local user denial of service attacks. Note: the fix for CVE-2019-9705 imposes a limitation on the length of a crontab file (the vulnerability was that an unlimited size crontab file could cause excessive memory consumption). https://security-tracker.debian.org/tracker/DLA-1723-1Vulnerable: <= 3.0pl1-cl3u1 Fixed: 3.0pl1-cl3u2 | 3.0.0-3.7.12 | 3.7.13-3.7.14 |

| CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior:
| 3.7.11-3.7.14 | |
| CM-27586 | CPU usage might be higher than normal if you have a high number of interfaces x VLANs and lldpd is active. This issue is introduced with code changes in Cumulus Linux 3.7.11, where VLAN information is now available for LLDP to advertise to neighbors (https://docs.cumulusnetworks.com/version/cumulus-linux-37/Layer-2/Link-Layer-Discovery-Protocol/#vlan-dot1-tlv). You might see high CPU usage even if VLAN (dot1) TLV configuration is disabled.To check if lldpd is the heavy CPU resource user, run the following command:cumulus@switch:~$ ps -eo user,pid,ppid,cmd,%mem,%cpu –sort=-%cpu | head Alternatively, check for messages in the /var/log/syslog directory similar to:2020-02-20T15:02:12.137857-05:00 leaf01 sysmonitor: High CPU use: 87% Note: The exact amount of CPU usage varies in each network based on a number of factors; however, it is unusual for lldpd to consume more than 30% CPU for an extended period of time.To work around this issue, you can do one of the following:
| 3.7.11-3.7.12 | 3.7.13-3.7.14 |
| CM-27581 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.14 | |
| CM-27530 | When hal.bcm.per_vlan_router_mac_lookup is set to TRUE in the /etc/cumulus/switchd.conf file, inter-VLAN traffic is forwarded to the CPU when associated VNI interfaces exist. | 3.7.10-3.7.14 | |
| CM-27522 | The NCLU command net show interface produces an error if bonds with no members exist.To work around this issue, remove the empty Bond interfaces from the /etc/network/interfaces file and run sudo ifreload -a. | 3.7.10-3.7.14 | |
| CM-27354 | On the Celestica Pebble switch, if you use IPv6 routes with mask /65 to /127, the switchd log fills with errors. | 3.7.10-3.7.13 | 3.7.14 |
| CM-27279 | When ECMP routes have both VXLAN (symmetric routing) and non-VXLAN paths, the non-VXLAN path is incorrectly installed in the RIB and FIB to point across VXLAN. The non-VXLAN next-hop will be installed as an offload entry in the neighbor table (ip neigh show) with a mac address of 00:00:00:00:00:00. | 3.7.3-3.7.14 | |
| CM-27192 | If you use NCLU commands to add a non-MLAG bond, then add an MLAG configuration, the net commit command fails. However, a subsequent net commit command succeeds. | 3.7.10-3.7.14 | |
| CM-27173 | On the Trident3 switch, unicast ARP packets received on a VNI and forwarded to the CPU are not policed. | 3.7.10-3.7.13 | 3.7.14 |
| CM-27094 | On the Delta AG9032v1 switch, smonctl and sensors report inaccurate PSU current and power. | 3.5.0-3.7.14 | |
| CM-27018 | If you configure more than one VRR interface on an SVI interface, deleting one of the VRR addresses does not remove the interface/address. | 3.7.10-3.7.14 | |
| CM-26921 | If you delete an undefined bond, then add a bond slave, the net commit command fails. | 3.7.9-3.7.14 | |
| CM-26913 | FRR configuration commands for an SVI interface might have the \n misplaced in the output. For example:sudo sh -c “printf ‘interface 50\nvrf TEST description L3 routing interface\n’ » /etc/frr/frr.conf" should be: sudo sh -c “printf ‘interface 50 vrf TEST\ndescription L3 routing interface\n’ » /etc/frr/frr.conf" To work around this issue, configure the interface manually in the /etc/frr/frr.conf file. | 3.7.9-3.7.14 | |
| CM-26905 | When you update the hostname of a switch with the NCLU net add hostname <hostname> command, then run net commit, the lldpd service does not restart and other devices still see the old hostname.To work around this issue, run the sudo systemctl restart lldpd.service command. | 3.7.10-3.7.14 | |
| CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-3.7.14 | |
| CM-26655 | If you reconfigure an NTP server with NCLU using different trailing options after the IP address (such as iburst), an invalid configuration is added to the /etc/ntp.conf file. For example:net add time ntp server 1.2.3.4 iburst If you need to alter existing server configurations, first remove the server, commit, then re-add the server with any trailing options. | 3.7.9-3.7.14 | |
| CM-26599 | Auto-negotiation does not work with the QSFP28 cables and a remote system operating at 10G. Attempting to enable auto-negotiation with ethtool -s swp<#> autoneg on returns Operation not supported.To work around this issue, do not use auto-negotiation and set the local port speed to 10G. | 3.7.9-3.7.14 | |
| CM-26595 | The NCLU net show lldp command displays the speed of a ganged port group as the speed of one of the individual links, rather than the sum of their speeds. | 3.7.9-3.7.14 | |
| CM-26516 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.14 | |
| CM-26463 | The following CVEs affect the linux kernel package: CVE-2019-14821 CVE-2019-14835 CVE-2019-15117 CVE-2019-15118 CVE-2019-15902 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | 3.7.10-3.7.14 | |
| CM-26423 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.14 | |
| CM-26412 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.14 | |
| CM-26288 | On the Mellanox switch, static VXLAN tunnels incorrectly allow traffic from any remote tunnel IP address. | 3.7.8-3.7.14 | |
| CM-26256 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.14 | |
| CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.14 | |
| CM-26225 | On the EdgeCore AS5712, AS6712, AS5812 and AS6812 switch, support for multiple PSU types results in log messages similar to the following:2019-09-05T05:15:17.246597+00:00 hp-6712-03 decode-syseeprom: Unable to find eeprom at /sys/bus/i2c/devices/11-0050/eeprom for psu2 | 3.7.9-3.7.12 | 3.7.13-3.7.14 |
| CM-26138 | You cannot specify a source and destination MAC address in an ERSPAN ebtables rule. For example, the following rule does not work:-A FORWARD -i swp5 -s 00:25:90:b2:bd:9d -d 50:6b:4b:96:c4:04 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:-A FORWARD -i vni10 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.14 | |
| CM-26136 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.14 | |
| CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.14 | |
| CM-26024 | On switches with the Spectrum ASIC, the underlay hashes VXLAN packets for a given overlay flow randomly. To work around this issue, configure the ECMP hash seed to the same value on the EVPN egress leaf switches. | 3.7.7-3.7.12 | 3.7.13-3.7.14 |
| CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-3.7.14 | |
| CM-25890 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.14 | |
| CM-25859 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.14 | |
| CM-25815 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.14 | |
| CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:ifdown vlan123 ; sleep 2 ; ifup vlan123 You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.14 | |
| CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.14 | |
| CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-3.7.14 | |
| CM-25740 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:cumulus@switch:~$ net add bridge mybridge vlan-protocol 802.1ad | 3.7.6-3.7.14 | |
| CM-25694 | If a packet is policed by ebtables, it does not increment an ACL drop on the ingress interface. Instead, it increments the TDBGC3/6 drop counter to the CPU. | 3.7.6-3.7.14 | |
| CM-25641 | If the BMC operating system fails to respond to IPMI, you see a traceback in bmcd and all the sensors might report ABSENT devices in smonctl.To work around this issue, power cycle the switch. | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.14 | |
| CM-25400 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.14 | |
| CM-25397 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.14 | |
| CM-25001 | The following CVEs were announced in Debian Security Advisory DSA-444-1, DSA-4447-1 and affect the linux kernel and microcode. Package: linux CVE ID: CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091 Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. Contact your hardware ndor for microcode uppdates. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver. Fixed in version 4.19.76-1+cl4u1 | 3.0.0-3.7.14 | |
| CM-24894 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.14 | |
| CM-24799 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.14 | |
| CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-3.7.14 | |
| CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.14 | |
| CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.14 | |
| CM-24652 | In an EVPN environment, the centralized MAC address is not installed on the MLAG pair because Cumulus Linux does not perform an SVI MAC check per VLAN. This issue does not affect a pure distributed routing (symmetric or asymmetric) environment or a pure centralized routing environment. | 3.7.0-3.7.14 | |
| CM-24618 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:ERROR: No closing quotation See /var/log/netd.log for more details. | 3.6.1-3.7.14 | |
| CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.14 | |
| CM-24435 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect: net add routing route-map Proxy-ARP permit 25 match interface swp9-10 These commands are correct: net add routing route-map Proxy-ARP permit 25 match interface swp9 net add routing route-map Proxy-ARP permit 30 match interface swp10 | 3.7.2-3.7.14 | |
| CM-24426 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf <name> command just displays
Tab completion for the net add vrf <name> ip address <address> command works correctly. | 3.7.4-3.7.14 | |
| CM-24379 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.14 | |
| CM-24343 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.14 | |
| CM-24332 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.14 | |
| CM-24272 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface br0.100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# vrrp 1 advertisement-interval switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24271 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface vlan100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24270 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface swp4 switch(config-if)# vrrp 1 version 2 switch(config-if)# no vrrp 1 preempt switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24262 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto <iface> lines exist. | 3.7.3-3.7.14 | |
| CM-24241 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:cumulus@switch:~$ net del bgp neighbor fabric peer-group ‘router bgp 65001’ configuration does not have ‘neighbor fabric peer-group’ | 3.7.2-3.7.14 | |
| CM-24222 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.14 | |
| CM-24035 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.14 | |
| CM-23825 | The net add interface <interface> ptm-enable command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.14 | |
| CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev <interface> command. | 3.7.0-3.7.14 | |
| CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.14 | |
| CM-23665 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan <layer3-vni> bridge access <vlan>. This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.14 | |
| CM-23661 | On the Mellanox switch, when you configure a GRE tunnel, the traffic behind the local tunnel endpoint destined through the GRE tunnel is software-forwarded. | 3.7.2-3.7.14 | |
| CM-23651 | In an EVPN symmetric routing configuration, when an IP address is frozen, kernel neighbor table information and kernel VRF routing table information about the frozen IP address might be out-of-sync. | 3.7.3-3.7.14 | |
| CM-23584 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.14 | |
| CM-23570 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.14 | |
| CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.14 | |
| CM-23418 | For QSFP modules, the sudo ifdown command does not disable the Tx laser. | 3.7.2-3.7.14 | |
| CM-23417 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.14 | |
| CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.6.2-3.7.14 | |
| CM-23125 | The OpenSSL package on Cumulus Linux 3.x has a vulnerability similar to CVE-2018-0734. (The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key). According to Debian upstream, this version “is not vulnerable [to CVE-2018-0734 exactly]. Nevertheless, there is a bug fix that futher reduces the amount of leaked timing information. It got no CVE on its own and introduced this vulnerability.“ Vulnerable on CL3: 1.0.1t-1+deb8u12 | 3.0.0-3.7.14 | |
| CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.14 | |
| CM-23075 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:2018-11-10T23:35:30.992370-08:00 Dev dhcrelay: Listening on LPF/vlan.101/a0:00:00:00:00:51 2018-11-10T23:35:30.993472-08:00 Dev dhcrelay: Sending on LPF/vlan.101/a0:00:00:00:00:51 Eventually the dhcrelay service stops. | 3.7.1-3.7.14 | |
| CM-23021 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.14 | |
| CM-23004 | The local fallback account authenticates using the local password when the RADIUS or TACACS service is up. The expected behavior is for this to fail and only succeed when the RADIUS OR TACACS server fails to respond. | 3.7.1-3.7.14 | |
| CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.6.0-3.7.14 | |
| CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.14 | |
| CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.5.2-3.7.14 | |
| CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.6.2-3.7.14 | |
| CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.6.0-3.7.14 | |
| CM-22554 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 3.6.2-3.7.14 | |
| CM-22386 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.14 | |
| CM-22301 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.A $INGRESS_CHAIN –in-interface $INGRESS_INTF -m addrtype –dst-type IPROUTER -j POLICE –set-mode pkt –set-rate 400 –set-burst 100 These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 3.6.1-3.7.14 | |
| CM-22287 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 3.6.2-3.7.14 | |
| CM-22274 | To ease interoperation with non-Cumulus devices, it is possible to configure the route-target import and export values under the layer 2 VNI EVPN configuration. The same configuration does not work for both layer 2 VNI and layer 3 VNIs. Set the EVPN address-family within the VNI context when configuring the route-target in the layer 2 VNI. Set the EVPN address-family without the VNI context when configuring the route-target in the layer 3 VNI. | 3.6.0-3.7.14 | |
| CM-22252 | On the Edgecore OMP-800, there is no Power Supply information from the sensor or from smonctl. The platform driver has support for the PSUs but this was not added to the sensors infrastructure.This is a known limitation on the OMP-800 platform. | 3.6.2-3.7.14 | |
| CM-22228 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.14 | |
| CM-22205 | If a user is in vtysh when FRR is restarted, the running configuration in that vtysh session shows empty. | 3.6.2-3.7.14 | |
| CM-22138 | When you run the NCLU net show system command or the NetQ netq inventory command on the Edgecore OMP-800 switch, the output does not show any port or chip information. | 3.6.2-3.7.14 | |
| CM-22041 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.4.3-3.7.14 | |
| CM-22020 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.14 | |
| CM-21898 | On a Trident3 switch, IGMP packets are not policed by the police rule in the 00control ACL file. The packets are policed by the catchall policer in the 99control ACL file instead.-A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100To work around this issue, let the CPU bound IGMP packet hit the following rule and change the policer rate to a desired value for IGMP packets: -A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100Typically, the destination MAC address 01:00:5e:xx:xx:xx is used only for PIM/IGMP control and data stream packets. However, this workaround cannot handle data stream multicast packets that are not TCP/UDP; this is not typically done. | 3.6.2-3.7.12 | 3.7.13-3.7.14 |
| CM-21785 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 3.6.2-3.7.14 | |
| CM-21769 | On the Mellanox switch, GRE tunneling does not work if the tunnel source is configured on an SVI interface. If the tunnel source is configured on a physical switch port, then tunneling works as expected. | 3.6.1-3.7.13 | 3.7.14 |
| CM-21678 | On a Dell switch with a Maverick ASIC, NetQ might receive false alerts like the following via PagerDuty: cumulus@switch:~$ netq show sensors temp changes | grep absent | grep -v psu P2Leaf01 temp9 networking asic die temp sensor absent 43 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 47 105 100 5 Unable to read temp4_highest Add 9d:23h:26m:6s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to read temp4_highest Add 14d:22h:46m:45s This message might occur as a result of a timeout at the hardware level, or the switch might be reporting a failure to get a response. | 3.5.3-3.7.14 | |
| CM-21667 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 3.6.1-3.7.14 | |
| CM-21379 | If a primary route becomes unavailable (for example, you run ifdown on the switch port), the backup route remains inactive and is not installed into FIB.To work around this issue, configure routes as ECMP: cumulus@switch:~$ net del routing route 4.1.1.0/24 1.1.1.1 10 cumulus@switch:~$ net add routing route 4.1.1.0/24 1.1.1.1 cumulus@switch:~$ net commit | 3.5.3-3.7.14 | |
| CM-21332 | When two VLAN subinterfaces are bridged to each other in a traditional mode bridge, switchd doesn’t assign a gport to the subinterface, even though a gport is expected for each VLAN subinterface.To work around this issue, you can do one of two things:
| 3.5.3-3.7.14 | |
| CM-21058 | The advertised routes list may be empty for an EVPN peering even though the remote switch reports received routes. | 3.6.0-3.7.14 | |
| CM-21055 | On the Mellanox switch, the destination MAC address of ERSPAN GRE packets is set to all zeros; therefore, the first transit switch might drop packets. | 3.6.0-3.7.13 | 3.7.14 |
| CM-20813 | Span rules matching the out-interface as a bond do not mirror packets. | 3.6.0-3.7.14 | |
| CM-20693 | In NCLU, you can only set the community number in a route map. You cannot set other community options such as no-export, no-advertise, or additive.This is a known limitation in network-docopt and is documented in the Cumulus Linux user guide. | 3.5.1-3.7.14 | |
| CM-20508 | The Cumulus-Resource-Query-MIB defines the ability to gather buffer utilization status but when these objects are polled, they return nothing. | 3.5.3-3.7.14 | |
| CM-20480 | The python-crypto package, which is not installed by default on Cumulus Linux, but is present in the repository to be installed, has the following security vulnerability in the version available for Cumulus Linux 3.x: CVE-2018-6594: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto’s ElGamal implementation. More information at https://security-tracker.debian.org/tracker/CVE-2018-6594 . | 3.0.0-3.7.14 | |
| CM-20033 | The VLAN interface stays up even though the physical link carrying the VLAN is admin or carrier down. | 3.5.2-3.7.14 | |
| CM-19788 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.5.0-3.7.14 | |
| CM-19724 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 3.5.2-3.7.14 | |
| CM-19454 | When you use NCLU to bring a bond admin down (net add bond <bond> link down), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown <bondname> command. | 3.5.0-3.7.14 | |
| CM-19006 | On the Broadcom Trident II+, Trident 3, and Maverick based switch, in an external VXLAN routing environment, when a lookup is done on the external-facing switch (exit/border leaf) after VXLAN decapsulation, the switch does not rewrite the MAC addresses and TTL; for through traffic, packets are dropped by the next hop instead of correctly routing from a VXLAN overlay network into a non-VXLAN external network (for example, to the Internet). This applies to all forms of VXLAN routing (centralized, asymmetric and symmetric) and affects all traffic from VXLAN overlay hosts that need to be routed after VXLAN decapsulation on an exit/border leaf, including:
For example, if the expected interface configuration is: auto swp3.2001 iface swp3.2001 vrf vrf1 address 45.0.0.2/24 # where swp3 is the external facing port and swp3.2001 is the VLAN subinterface auto bridge iface bridge bridge-vlan-aware yes bridge ports vx-4001 bridge-vids 4001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 Modify the configuration as follows: auto swp3 iface swp3 bridge-access 2001 # associate the port (swp3) with bridge 2001 auto bridge iface bridge bridge-vlan-aware yes bridge ports swp3 vx-4001 vx-16000000 bridge-vids 4001 2001 # where vx-4001 is the existing VNI and vx-16000000 is a new temporary VNI # this is now bridging the port (swp3), the VNI (vx-4001), # and the new temporary VNI (vx-16000000) # the bridge VLAN IDs are now 4001 and 2001 auto vlan2001 iface vlan2001 vlan-id 2001 vrf vrf1 address 45.0.0.2/24 vlan-raw-device bridge # create a VLAN 2001 with the associated VRF and IP address auto vx-16000000 iface vx-16000000 vxlan-id 16000000 bridge-access 2001 <… usual vxlan config …> # associate the temporary VNI (vx-16000000) with bridge 2001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 If an MLAG pair is used instead of a single exit/border leaf, the same temporary VNIs should be added on both switches of the MLAG pair. on the Broadcom Trident 3 switch. Note: This issue still exists on the Broadcom Trident II+ and Maverick-based switch. | 3.5.0-3.7.14 | |
| CM-18192 | In FRR, bgp_snmp does not show all BGP peers when peer groups used. | 3.7.11-3.7.14 | |
| CM-17934 | FRR tracks interface speed based on the value it learns from the Linux kernel for that interface. If the interface speed changes, FRR does not update its interface speed cache. This can lead to issues for routing protocols that derive metrics from interface speed as the cost can become out of sync with the interface speed. To work around this issue, manually define the routing protocol metric for these interfaces or restart FRR. | 3.7.6-3.7.14 | |
| CM-17557 | When sFlow is enabled, some sampled packets, such as IPMC, are forwarded twice (in the ASIC and then again through the kernel networking stack). | 3.4.0-3.7.14 | |
| CM-17494 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See Address Resolution Protocol in the Cumulus Linux user guide for more information. | 3.3.2-3.7.14 | |
| CM-16855 | If a two nodes on both sides of a link change from auto-negotiation off to auto-negotiation on for both sides during a short interval (around one second), the link might start flapping or stay down.To work around this issue and stop the flapping, turn the link down on the switch with the command ifdown swpX, wait a few seconds, then bring the link back up with the command ifup swpX. Repeat this on the other side if necessary. | 3.3.2-3.7.14 | |
| CM-16571 | NCLU cannot manage rsyslog to addresses routed via a VRF. In Cumulus Linux 4.0.0 and later, management VRF is enabled by default. To work around this issue, update the /etc/network/interfaces file to disable management VRF. | 3.4.3-3.7.14 | |
| CM-16461 | After booting a Cumulus VX virtual machine running the VMware OVA image, sometimes messages from sensors appear, indicating that the “Avg state” is critical, with all values displayed as 100.0. A cl-support is generated. | 3.4.2-3.7.14 | |
| CM-15812 | Multicast forwarding fails for IP addresses whose DMAC overlaps with reserved DIPs. | 3.2.1-3.7.14 | |
| CM-15601 | On a Mellanox switch in an MLAG configuration, routed packets that arrive on one switch to be forwarded to a destination MAC across the peer link are dropped due to MLAG loop prevention. This affects both routed unicast and multicast packets.To work around this issue, modify the routing design or policy such that routes do not have a next hop of an MLAG peer switch that traverses the MLAG peer link. | 3.6.2-3.7.13 | 3.7.14 |
| CM-15094 | Counter samples for an 80G bond (2 x 40G) exported from the switch show an interface speed (ifSpeed) of 14.464Gbps. | 3.2.0-3.7.14 |

| CM-27525 | On the Delta AG6248C PoE switch, if the PoE priority is set to low on some ports, other ports with a higher priority might have their requests to draw power rejected instead of the lower priority ports being brought down. | 3.7.11 |
| CM-27507 | The ports.conf file on the Dell S5248F-ON switch does not show port ganging or breakout options. | 3.7.10-3.7.11 |
| CM-27496 | All Broadcom Trident3 X7 switches contain PCIE firmware, which is programmed by the vendor when the switch is manufactured. The latest version of this firmware (2.6) is incompatible with Cumulus Linux 3.7.11 and earlier, and Cumulus Linux 4.0. To work around this issue, downgrade the Broadcom ASIC firmware to an earlier version. | 3.7.11 |
| CM-27444 | If you use the NCLU commands to configure NTP and run the net add time ntp source <interface> command before you run the net add time ntp server <server> iburst command, the /etc/ntp.conf file is misconfigured.To work around this issue, run the net add time ntp server <server> iburst command before you run the net add time ntp source <interface> command. | 3.7.10-3.7.11 |
| CM-27295 | IPv6 table rules might affect forwarding. For example, if you create the following rule in the /etc/cumulus/acl/policy.d/03-sshd.rules file, the rule counter increments but IPv4 SSH traffic might be dropped.[ip6tables] | 3.7.2-3.7.11 |
| CM-27120 | When an interface flap occurs, numbered IPv6 BGP sessions might fail to establish. To work around this issue, run the ip -6 route flush cache <IPv6-address> command to flush the IPv6 route cache. | 3.7.9-3.7.11 |
| CM-26894 | The neighmgrd service does not ignore neighbors on reserved devices (lo and management devices). This issue is not seen when management VRF is enabled. | 3.7.8-3.7.11 |
| CM-26839 | On the Dell S5248F-ON switch, CPU core temp sensors may show as ABSENT. | |
| CM-26351 | After you remove a subinterface, the BGP session stays in a Connect state. | 3.7.8-3.7.11 |
| CM-26241 | On the Dell S5248F-ON switch, smond might generate syslog messages indicating that the fan input RPM is lower than the normal low speed of 2500 RPM. Speeds as low as 1700 RPM are acceptable in normal thermal environments; therefore, you can ignore these messages. | 3.7.6-3.7.11 |
| CM-25665 | On the Broadcom Trident 3 switch, VXLAN encapsulated packets are dropped on the ingress port (tagged layer 2 port) during transit forwarding (the local switch does not terminate the VXLAN tunnel). An example of where this two-layer VXLAN inside VXLAN encapsulation might occur:
| 3.7.5-3.7.11 |
| CM-22591 | CVE-2018-5391 (FragmentSmack) is a network vulnerability where an attacker can trigger time and calculation expensive fragment reassembly with specially crafted packets, leading to a denial of service. On a Cumulus Linux switch, the impact is limited to control plane and management plane traffic. Any control plane traffic coming in the front panel ports will be limited by existing policer ACLs. To work around this issue, create a file called /etc/sysctl.d/ip.conf and add these settings:net.ipv4.ipfrag_low_thresh = 196608 | 3.7.0-3.7.11 |

| CM-33008 | Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed. CVE-2020-19667 Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c CVE-2020-25665 The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. This could cause impact to reliability. CVE-2020-25674 WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. CVE-2020-27560 ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service. CVE-2020-27750 A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould trigger undefined behavior in the form of values outside the range of type unsigned char and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27760 In GammaImage() of /MagickCore/enhance.c, depending on the gamma value, it’s possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. CVE-2020-27763 A flaw was found in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27765 A flaw was found in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27773 A flaw was found in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-29599 ImageMagick mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.

| CM-30863 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.0.0-3.7.14 | |

| CM-27683 | The following CVEs were announced that affect the Linux kernel: CVE-2019-12378: An issue was discovered in ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). CVE-2019-12381: An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). CVE-2019-15239: In the Linux kernel, a certain net/ipv4/tcp_output.c change, which was properly incorporated into 4.16.12, was incorrectly backported to the earlier longterm kernels, introducing a new vulnerability that was potentially more severe than the issue that was intended to be fixed by backporting. Specifically, by adding to a write queue between disconnection and re-connection, a local attacker can trigger multiple use-after-free conditions. This can result in a kernel crash, or potentially in privilege escalation. CVE-2019-19062: A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042. CVE-2019-19537: In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer, aka CID-303911cfc5b9. This affects drivers/usb/core/file.c. CVE-2019-20054: In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. | 3.0.0-3.7.11 | 3.7.12-3.7.14 |
| CM-27670 | A memory leak in switchd might occur, which causes switchd to restart. | 3.7.10-3.7.11 | 3.7.12-3.7.14 |
| CM-27646 | Several vulnerabilities have been discovered in Git, a fast, scalable, distributed revision control system, which is available in the Cumulus Linux 3.x repositories for optional installation. CVE-2019-1348: export-marks is insecure, fix is to disable by default. CVE-2019-1349: .git / git~1 filename vulnerability on NTFS CVE-2019-1352: .git vulnerability with NTFS Alternate Streams Accesses CVE-2019-1353: NTFS filesystem protection should be on by default CVE-2019-1387: dubiously-nested submodule git directories should be disallowed CVE-2019-19604: submodule update repository code execution vulnerability Vulnerable: <= 2.1.4-2.1+deb8u7 Fixed: 2.1.4-2.1+deb8u8 | 3.0.0-3.7.12 | 3.7.13-3.7.14 |
| CM-27644 | Ifupdown2 does not set up the front panel interface for the dhclient to accept the DHCP OFFER.To work around this issue, restart the networking service after ifreload -a with the systemctl restart networking command. | 3.7.10-3.7.11 | 3.7.12-3.7.14 |
| CM-27620 | When using QinQ with a traditional bridge, if you enable the LLDP dot1 TLV option, you see the following suboptimal behavior:
| 3.7.11-3.7.14 | |
| CM-27586 | CPU usage might be higher than normal if you have a high number of interfaces x VLANs and lldpd is active. This issue is introduced with code changes in Cumulus Linux 3.7.11, where VLAN information is now available for LLDP to advertise to neighbors (https://docs.cumulusnetworks.com/version/cumulus-linux-37/Layer-2/Link-Layer-Discovery-Protocol/#vlan-dot1-tlv). You might see high CPU usage even if VLAN (dot1) TLV configuration is disabled.To check if lldpd is the heavy CPU resource user, run the following command:cumulus@switch:~$ ps -eo user,pid,ppid,cmd,%mem,%cpu –sort=-%cpu | head Alternatively, check for messages in the /var/log/syslog directory similar to:2020-02-20T15:02:12.137857-05:00 leaf01 sysmonitor: High CPU use: 87% Note: The exact amount of CPU usage varies in each network based on a number of factors; however, it is unusual for lldpd to consume more than 30% CPU for an extended period of time.To work around this issue, you can do one of the following:
| 3.7.11-3.7.12 | 3.7.13-3.7.14 |
| CM-27581 | On the Delta AG-6248C PoE switch, when you run the apt upgrade command, the upgrade does not work. Cumulus Linux uses uboot directly instead of grub to boot the kernel. Uboot needs a special header to boot the kernel, which is not present. Without this header, when you use the apt upgrade command to upgrade Linux packages, uboot is unable to boot up the kernel.To work around this issue, upgrade Cumulus Linux by installing the Cumulus Linux image. Run the onie-select command to go into ONIE, and then use the nos-install command in ONIE to install a new image.This workaround only works when an out-of-band network is present. | 3.7.11-3.7.14 | |
| CM-27530 | When hal.bcm.per_vlan_router_mac_lookup is set to TRUE in the /etc/cumulus/switchd.conf file, inter-VLAN traffic is forwarded to the CPU when associated VNI interfaces exist. | 3.7.10-3.7.14 | |
| CM-27525 | On the Delta AG6248C PoE switch, if the PoE priority is set to low on some ports, other ports with a higher priority might have their requests to draw power rejected instead of the lower priority ports being brought down. | 3.7.11 | 3.7.12-3.7.14 |
| CM-27522 | The NCLU command net show interface produces an error if bonds with no members exist.To work around this issue, remove the empty Bond interfaces from the /etc/network/interfaces file and run sudo ifreload -a. | 3.7.10-3.7.14 | |
| CM-27507 | The ports.conf file on the Dell S5248F-ON switch does not show port ganging or breakout options. | 3.7.10-3.7.11 | 3.7.12-3.7.14 |
| CM-27496 | All Broadcom Trident3 X7 switches contain PCIE firmware, which is programmed by the vendor when the switch is manufactured. The latest version of this firmware (2.6) is incompatible with Cumulus Linux 3.7.11 and earlier, and Cumulus Linux 4.0. To work around this issue, downgrade the Broadcom ASIC firmware to an earlier version. | 3.7.11 | 3.7.12-3.7.14 |
| CM-27444 | If you use the NCLU commands to configure NTP and run the net add time ntp source <interface> command before you run the net add time ntp server <server> iburst command, the /etc/ntp.conf file is misconfigured.To work around this issue, run the net add time ntp server <server> iburst command before you run the net add time ntp source <interface> command. | 3.7.10-3.7.11 | 3.7.12-3.7.14 |
| CM-27354 | On the Celestica Pebble switch, if you use IPv6 routes with mask /65 to /127, the switchd log fills with errors. | 3.7.10-3.7.13 | 3.7.14 |
| CM-27295 | IPv6 table rules might affect forwarding. For example, if you create the following rule in the /etc/cumulus/acl/policy.d/03-sshd.rules file, the rule counter increments but IPv4 SSH traffic might be dropped.[ip6tables] | 3.7.2-3.7.11 | 3.7.12-3.7.14 |
| CM-27279 | When ECMP routes have both VXLAN (symmetric routing) and non-VXLAN paths, the non-VXLAN path is incorrectly installed in the RIB and FIB to point across VXLAN. The non-VXLAN next-hop will be installed as an offload entry in the neighbor table (ip neigh show) with a mac address of 00:00:00:00:00:00. | 3.7.3-3.7.14 | |
| CM-27192 | If you use NCLU commands to add a non-MLAG bond, then add an MLAG configuration, the net commit command fails. However, a subsequent net commit command succeeds. | 3.7.10-3.7.14 | |
| CM-27173 | On the Trident3 switch, unicast ARP packets received on a VNI and forwarded to the CPU are not policed. | 3.7.10-3.7.13 | 3.7.14 |
| CM-27120 | When an interface flap occurs, numbered IPv6 BGP sessions might fail to establish. To work around this issue, run the ip -6 route flush cache <IPv6-address> command to flush the IPv6 route cache. | 3.7.9-3.7.11 | 3.7.12-3.7.14 |
| CM-27094 | On the Delta AG9032v1 switch, smonctl and sensors report inaccurate PSU current and power. | 3.5.0-3.7.14 | |
| CM-27018 | If you configure more than one VRR interface on an SVI interface, deleting one of the VRR addresses does not remove the interface/address. | 3.7.10-3.7.14 | |
| CM-26921 | If you delete an undefined bond, then add a bond slave, the net commit command fails. | 3.7.9-3.7.14 | |
| CM-26913 | FRR configuration commands for an SVI interface might have the \n misplaced in the output. For example:sudo sh -c “printf ‘interface 50\nvrf TEST description L3 routing interface\n’ » /etc/frr/frr.conf" should be: sudo sh -c “printf ‘interface 50 vrf TEST\ndescription L3 routing interface\n’ » /etc/frr/frr.conf" To work around this issue, configure the interface manually in the /etc/frr/frr.conf file. | 3.7.9-3.7.14 | |
| CM-26905 | When you update the hostname of a switch with the NCLU net add hostname <hostname> command, then run net commit, the lldpd service does not restart and other devices still see the old hostname.To work around this issue, run the sudo systemctl restart lldpd.service command. | 3.7.10-3.7.14 | |
| CM-26894 | The neighmgrd service does not ignore neighbors on reserved devices (lo and management devices). This issue is not seen when management VRF is enabled. | 3.7.8-3.7.11 | 3.7.12-3.7.14 |
| CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-3.7.14 | |
| CM-26655 | If you reconfigure an NTP server with NCLU using different trailing options after the IP address (such as iburst), an invalid configuration is added to the /etc/ntp.conf file. For example:net add time ntp server 1.2.3.4 iburst If you need to alter existing server configurations, first remove the server, commit, then re-add the server with any trailing options. | 3.7.9-3.7.14 | |
| CM-26599 | Auto-negotiation does not work with the QSFP28 cables and a remote system operating at 10G. Attempting to enable auto-negotiation with ethtool -s swp<#> autoneg on returns Operation not supported.To work around this issue, do not use auto-negotiation and set the local port speed to 10G. | 3.7.9-3.7.14 | |
| CM-26595 | The NCLU net show lldp command displays the speed of a ganged port group as the speed of one of the individual links, rather than the sum of their speeds. | 3.7.9-3.7.14 | |
| CM-26516 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.14 | |
| CM-26463 | The following CVEs affect the linux kernel package: CVE-2019-14821 CVE-2019-14835 CVE-2019-15117 CVE-2019-15118 CVE-2019-15902 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | 3.7.10-3.7.14 | |
| CM-26423 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.14 | |
| CM-26412 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.14 | |
| CM-26351 | After you remove a subinterface, the BGP session stays in a Connect state. | 3.7.8-3.7.11 | 3.7.12-3.7.14 |
| CM-26288 | On the Mellanox switch, static VXLAN tunnels incorrectly allow traffic from any remote tunnel IP address. | 3.7.8-3.7.14 | |
| CM-26256 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.14 | |
| CM-26241 | On the Dell S5248F-ON switch, smond might generate syslog messages indicating that the fan input RPM is lower than the normal low speed of 2500 RPM. Speeds as low as 1700 RPM are acceptable in normal thermal environments; therefore, you can ignore these messages. | 3.7.6-3.7.11 | 3.7.12-3.7.14 |
| CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.14 | |
| CM-26225 | On the EdgeCore AS5712, AS6712, AS5812 and AS6812 switch, support for multiple PSU types results in log messages similar to the following:2019-09-05T05:15:17.246597+00:00 hp-6712-03 decode-syseeprom: Unable to find eeprom at /sys/bus/i2c/devices/11-0050/eeprom for psu2 | 3.7.9-3.7.12 | 3.7.13-3.7.14 |
| CM-26138 | You cannot specify a source and destination MAC address in an ERSPAN ebtables rule. For example, the following rule does not work:-A FORWARD -i swp5 -s 00:25:90:b2:bd:9d -d 50:6b:4b:96:c4:04 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:-A FORWARD -i vni10 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.14 | |
| CM-26136 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.14 | |
| CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.14 | |
| CM-26024 | On switches with the Spectrum ASIC, the underlay hashes VXLAN packets for a given overlay flow randomly. To work around this issue, configure the ECMP hash seed to the same value on the EVPN egress leaf switches. | 3.7.7-3.7.12 | 3.7.13-3.7.14 |
| CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-3.7.14 | |
| CM-25890 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.14 | |
| CM-25859 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.14 | |
| CM-25815 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.14 | |
| CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:ifdown vlan123 ; sleep 2 ; ifup vlan123 You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.14 | |
| CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.14 | |
| CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-3.7.14 | |
| CM-25740 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:cumulus@switch:~$ net add bridge mybridge vlan-protocol 802.1ad | 3.7.6-3.7.14 | |
| CM-25694 | If a packet is policed by ebtables, it does not increment an ACL drop on the ingress interface. Instead, it increments the TDBGC3/6 drop counter to the CPU. | 3.7.6-3.7.14 | |
| CM-25665 | On the Broadcom Trident 3 switch, VXLAN encapsulated packets are dropped on the ingress port (tagged layer 2 port) during transit forwarding (the local switch does not terminate the VXLAN tunnel). An example of where this two-layer VXLAN inside VXLAN encapsulation might occur:
| 3.7.5-3.7.11 | 3.7.12-3.7.14 |
| CM-25641 | If the BMC operating system fails to respond to IPMI, you see a traceback in bmcd and all the sensors might report ABSENT devices in smonctl.To work around this issue, power cycle the switch. | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.14 | |
| CM-25400 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.14 | |
| CM-25397 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.14 | |
| CM-25001 | The following CVEs were announced in Debian Security Advisory DSA-444-1, DSA-4447-1 and affect the linux kernel and microcode. Package: linux CVE ID: CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091 Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. Contact your hardware ndor for microcode uppdates. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver. Fixed in version 4.19.76-1+cl4u1 | 3.0.0-3.7.14 | |
| CM-24894 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.14 | |
| CM-24799 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.14 | |
| CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-3.7.14 | |
| CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.14 | |
| CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.14 | |
| CM-24652 | In an EVPN environment, the centralized MAC address is not installed on the MLAG pair because Cumulus Linux does not perform an SVI MAC check per VLAN. This issue does not affect a pure distributed routing (symmetric or asymmetric) environment or a pure centralized routing environment. | 3.7.0-3.7.14 | |
| CM-24618 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:ERROR: No closing quotation See /var/log/netd.log for more details. | 3.6.1-3.7.14 | |
| CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.14 | |
| CM-24435 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect: net add routing route-map Proxy-ARP permit 25 match interface swp9-10 These commands are correct: net add routing route-map Proxy-ARP permit 25 match interface swp9 net add routing route-map Proxy-ARP permit 30 match interface swp10 | 3.7.2-3.7.14 | |
| CM-24426 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf <name> command just displays
Tab completion for the net add vrf <name> ip address <address> command works correctly. | 3.7.4-3.7.14 | |
| CM-24379 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.14 | |
| CM-24343 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.14 | |
| CM-24332 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.14 | |
| CM-24272 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface br0.100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# vrrp 1 advertisement-interval switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24271 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface vlan100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24270 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface swp4 switch(config-if)# vrrp 1 version 2 switch(config-if)# no vrrp 1 preempt switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24262 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto <iface> lines exist. | 3.7.3-3.7.14 | |
| CM-24241 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:cumulus@switch:~$ net del bgp neighbor fabric peer-group ‘router bgp 65001’ configuration does not have ‘neighbor fabric peer-group’ | 3.7.2-3.7.14 | |
| CM-24222 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.14 | |
| CM-24035 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.14 | |
| CM-23825 | The net add interface <interface> ptm-enable command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.14 | |
| CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev <interface> command. | 3.7.0-3.7.14 | |
| CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.14 | |
| CM-23665 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan <layer3-vni> bridge access <vlan>. This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.14 | |
| CM-23661 | On the Mellanox switch, when you configure a GRE tunnel, the traffic behind the local tunnel endpoint destined through the GRE tunnel is software-forwarded. | 3.7.2-3.7.14 | |
| CM-23651 | In an EVPN symmetric routing configuration, when an IP address is frozen, kernel neighbor table information and kernel VRF routing table information about the frozen IP address might be out-of-sync. | 3.7.3-3.7.14 | |
| CM-23584 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.14 | |
| CM-23570 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.14 | |
| CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.14 | |
| CM-23418 | For QSFP modules, the sudo ifdown command does not disable the Tx laser. | 3.7.2-3.7.14 | |
| CM-23417 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.14 | |
| CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.6.2-3.7.14 | |
| CM-23125 | The OpenSSL package on Cumulus Linux 3.x has a vulnerability similar to CVE-2018-0734. (The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key). According to Debian upstream, this version “is not vulnerable [to CVE-2018-0734 exactly]. Nevertheless, there is a bug fix that futher reduces the amount of leaked timing information. It got no CVE on its own and introduced this vulnerability.“ Vulnerable on CL3: 1.0.1t-1+deb8u12 | 3.0.0-3.7.14 | |
| CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.14 | |
| CM-23075 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:2018-11-10T23:35:30.992370-08:00 Dev dhcrelay: Listening on LPF/vlan.101/a0:00:00:00:00:51 2018-11-10T23:35:30.993472-08:00 Dev dhcrelay: Sending on LPF/vlan.101/a0:00:00:00:00:51 Eventually the dhcrelay service stops. | 3.7.1-3.7.14 | |
| CM-23021 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.14 | |
| CM-23004 | The local fallback account authenticates using the local password when the RADIUS or TACACS service is up. The expected behavior is for this to fail and only succeed when the RADIUS OR TACACS server fails to respond. | 3.7.1-3.7.14 | |
| CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.6.0-3.7.14 | |
| CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.14 | |
| CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.5.2-3.7.14 | |
| CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.6.2-3.7.14 | |
| CM-22591 | CVE-2018-5391 (FragmentSmack) is a network vulnerability where an attacker can trigger time and calculation expensive fragment reassembly with specially crafted packets, leading to a denial of service. On a Cumulus Linux switch, the impact is limited to control plane and management plane traffic. Any control plane traffic coming in the front panel ports will be limited by existing policer ACLs. To work around this issue, create a file called /etc/sysctl.d/ip.conf and add these settings:net.ipv4.ipfrag_low_thresh = 196608 | 3.7.0-3.7.11 | 3.7.12-3.7.14 |
| CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.6.0-3.7.14 | |
| CM-22554 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 3.6.2-3.7.14 | |
| CM-22386 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.14 | |
| CM-22301 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.A $INGRESS_CHAIN –in-interface $INGRESS_INTF -m addrtype –dst-type IPROUTER -j POLICE –set-mode pkt –set-rate 400 –set-burst 100 These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 3.6.1-3.7.14 | |
| CM-22287 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 3.6.2-3.7.14 | |
| CM-22274 | To ease interoperation with non-Cumulus devices, it is possible to configure the route-target import and export values under the layer 2 VNI EVPN configuration. The same configuration does not work for both layer 2 VNI and layer 3 VNIs. Set the EVPN address-family within the VNI context when configuring the route-target in the layer 2 VNI. Set the EVPN address-family without the VNI context when configuring the route-target in the layer 3 VNI. | 3.6.0-3.7.14 | |
| CM-22252 | On the Edgecore OMP-800, there is no Power Supply information from the sensor or from smonctl. The platform driver has support for the PSUs but this was not added to the sensors infrastructure.This is a known limitation on the OMP-800 platform. | 3.6.2-3.7.14 | |
| CM-22228 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.14 | |
| CM-22205 | If a user is in vtysh when FRR is restarted, the running configuration in that vtysh session shows empty. | 3.6.2-3.7.14 | |
| CM-22138 | When you run the NCLU net show system command or the NetQ netq inventory command on the Edgecore OMP-800 switch, the output does not show any port or chip information. | 3.6.2-3.7.14 | |
| CM-22041 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.4.3-3.7.14 | |
| CM-22020 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.14 | |
| CM-21898 | On a Trident3 switch, IGMP packets are not policed by the police rule in the 00control ACL file. The packets are policed by the catchall policer in the 99control ACL file instead.-A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100To work around this issue, let the CPU bound IGMP packet hit the following rule and change the policer rate to a desired value for IGMP packets: -A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100Typically, the destination MAC address 01:00:5e:xx:xx:xx is used only for PIM/IGMP control and data stream packets. However, this workaround cannot handle data stream multicast packets that are not TCP/UDP; this is not typically done. | 3.6.2-3.7.12 | 3.7.13-3.7.14 |
| CM-21785 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 3.6.2-3.7.14 | |
| CM-21769 | On the Mellanox switch, GRE tunneling does not work if the tunnel source is configured on an SVI interface. If the tunnel source is configured on a physical switch port, then tunneling works as expected. | 3.6.1-3.7.13 | 3.7.14 |
| CM-21678 | On a Dell switch with a Maverick ASIC, NetQ might receive false alerts like the following via PagerDuty: cumulus@switch:~$ netq show sensors temp changes | grep absent | grep -v psu P2Leaf01 temp9 networking asic die temp sensor absent 43 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 47 105 100 5 Unable to read temp4_highest Add 9d:23h:26m:6s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to read temp4_highest Add 14d:22h:46m:45s This message might occur as a result of a timeout at the hardware level, or the switch might be reporting a failure to get a response. | 3.5.3-3.7.14 | |
| CM-21667 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 3.6.1-3.7.14 | |
| CM-21379 | If a primary route becomes unavailable (for example, you run ifdown on the switch port), the backup route remains inactive and is not installed into FIB.To work around this issue, configure routes as ECMP: cumulus@switch:~$ net del routing route 4.1.1.0/24 1.1.1.1 10 cumulus@switch:~$ net add routing route 4.1.1.0/24 1.1.1.1 cumulus@switch:~$ net commit | 3.5.3-3.7.14 | |
| CM-21332 | When two VLAN subinterfaces are bridged to each other in a traditional mode bridge, switchd doesn’t assign a gport to the subinterface, even though a gport is expected for each VLAN subinterface.To work around this issue, you can do one of two things:
| 3.5.3-3.7.14 | |
| CM-21058 | The advertised routes list may be empty for an EVPN peering even though the remote switch reports received routes. | 3.6.0-3.7.14 | |
| CM-21055 | On the Mellanox switch, the destination MAC address of ERSPAN GRE packets is set to all zeros; therefore, the first transit switch might drop packets. | 3.6.0-3.7.13 | 3.7.14 |
| CM-20813 | Span rules matching the out-interface as a bond do not mirror packets. | 3.6.0-3.7.14 | |
| CM-20693 | In NCLU, you can only set the community number in a route map. You cannot set other community options such as no-export, no-advertise, or additive.This is a known limitation in network-docopt and is documented in the Cumulus Linux user guide. | 3.5.1-3.7.14 | |
| CM-20508 | The Cumulus-Resource-Query-MIB defines the ability to gather buffer utilization status but when these objects are polled, they return nothing. | 3.5.3-3.7.14 | |
| CM-20480 | The python-crypto package, which is not installed by default on Cumulus Linux, but is present in the repository to be installed, has the following security vulnerability in the version available for Cumulus Linux 3.x: CVE-2018-6594: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto’s ElGamal implementation. More information at https://security-tracker.debian.org/tracker/CVE-2018-6594 . | 3.0.0-3.7.14 | |
| CM-20033 | The VLAN interface stays up even though the physical link carrying the VLAN is admin or carrier down. | 3.5.2-3.7.14 | |
| CM-19788 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.5.0-3.7.14 | |
| CM-19724 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 3.5.2-3.7.14 | |
| CM-19454 | When you use NCLU to bring a bond admin down (net add bond <bond> link down), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown <bondname> command. | 3.5.0-3.7.14 | |
| CM-19006 | On the Broadcom Trident II+, Trident 3, and Maverick based switch, in an external VXLAN routing environment, when a lookup is done on the external-facing switch (exit/border leaf) after VXLAN decapsulation, the switch does not rewrite the MAC addresses and TTL; for through traffic, packets are dropped by the next hop instead of correctly routing from a VXLAN overlay network into a non-VXLAN external network (for example, to the Internet). This applies to all forms of VXLAN routing (centralized, asymmetric and symmetric) and affects all traffic from VXLAN overlay hosts that need to be routed after VXLAN decapsulation on an exit/border leaf, including:
For example, if the expected interface configuration is: auto swp3.2001 iface swp3.2001 vrf vrf1 address 45.0.0.2/24 # where swp3 is the external facing port and swp3.2001 is the VLAN subinterface auto bridge iface bridge bridge-vlan-aware yes bridge ports vx-4001 bridge-vids 4001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 Modify the configuration as follows: auto swp3 iface swp3 bridge-access 2001 # associate the port (swp3) with bridge 2001 auto bridge iface bridge bridge-vlan-aware yes bridge ports swp3 vx-4001 vx-16000000 bridge-vids 4001 2001 # where vx-4001 is the existing VNI and vx-16000000 is a new temporary VNI # this is now bridging the port (swp3), the VNI (vx-4001), # and the new temporary VNI (vx-16000000) # the bridge VLAN IDs are now 4001 and 2001 auto vlan2001 iface vlan2001 vlan-id 2001 vrf vrf1 address 45.0.0.2/24 vlan-raw-device bridge # create a VLAN 2001 with the associated VRF and IP address auto vx-16000000 iface vx-16000000 vxlan-id 16000000 bridge-access 2001 <… usual vxlan config …> # associate the temporary VNI (vx-16000000) with bridge 2001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 If an MLAG pair is used instead of a single exit/border leaf, the same temporary VNIs should be added on both switches of the MLAG pair. on the Broadcom Trident 3 switch. Note: This issue still exists on the Broadcom Trident II+ and Maverick-based switch. | 3.5.0-3.7.14 | |
| CM-18192 | In FRR, bgp_snmp does not show all BGP peers when peer groups used. | 3.7.11-3.7.14 | |
| CM-17934 | FRR tracks interface speed based on the value it learns from the Linux kernel for that interface. If the interface speed changes, FRR does not update its interface speed cache. This can lead to issues for routing protocols that derive metrics from interface speed as the cost can become out of sync with the interface speed. To work around this issue, manually define the routing protocol metric for these interfaces or restart FRR. | 3.7.6-3.7.14 | |
| CM-17557 | When sFlow is enabled, some sampled packets, such as IPMC, are forwarded twice (in the ASIC and then again through the kernel networking stack). | 3.4.0-3.7.14 | |
| CM-17494 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See Address Resolution Protocol in the Cumulus Linux user guide for more information. | 3.3.2-3.7.14 | |
| CM-16855 | If a two nodes on both sides of a link change from auto-negotiation off to auto-negotiation on for both sides during a short interval (around one second), the link might start flapping or stay down.To work around this issue and stop the flapping, turn the link down on the switch with the command ifdown swpX, wait a few seconds, then bring the link back up with the command ifup swpX. Repeat this on the other side if necessary. | 3.3.2-3.7.14 | |
| CM-16571 | NCLU cannot manage rsyslog to addresses routed via a VRF. In Cumulus Linux 4.0.0 and later, management VRF is enabled by default. To work around this issue, update the /etc/network/interfaces file to disable management VRF. | 3.4.3-3.7.14 | |
| CM-16461 | After booting a Cumulus VX virtual machine running the VMware OVA image, sometimes messages from sensors appear, indicating that the “Avg state” is critical, with all values displayed as 100.0. A cl-support is generated. | 3.4.2-3.7.14 | |
| CM-15812 | Multicast forwarding fails for IP addresses whose DMAC overlaps with reserved DIPs. | 3.2.1-3.7.14 | |
| CM-15601 | On a Mellanox switch in an MLAG configuration, routed packets that arrive on one switch to be forwarded to a destination MAC across the peer link are dropped due to MLAG loop prevention. This affects both routed unicast and multicast packets.To work around this issue, modify the routing design or policy such that routes do not have a next hop of an MLAG peer switch that traverses the MLAG peer link. | 3.6.2-3.7.13 | 3.7.14 |
| CM-15094 | Counter samples for an 80G bond (2 x 40G) exported from the switch show an interface speed (ifSpeed) of 14.464Gbps. | 3.2.0-3.7.14 |

| CM-27457 | If you delete, then re-add a PBR policy on an interface, the configured PBR policy is not programmed in the kernel or switchd. | 3.7.9-3.7.10 |
| CM-27456 | After making a series of PBR configuration changes using NCLU commands, the stale PBR entry is still present in the kernel. | 3.7.9-3.7.10 |
| CM-27351 | On rare occasions, after rebooting the MLAG secondary switch, one MLAG device might see the peer as down, which can cause traffic disruption to connected hosts. | 3.7.7-3.7.10 |
| CM-27321 | The following CVEs were announced that affect the ghostscript package: CVE-2019-14869: Manfred Paul and Lukas Schauer reported that the .charkeys procedure in Ghostscript, the GPL PostScript/PDF interpreter, does not properly restrict privileged calls, which could result in bypass of file system restrictions of the dSAFER sandbox. Cumulus Linux 3: <= 9.26a~dfsg-0+deb8u5 vulnerable, >= 9.26a~dfsg-0+deb8u6 fixed. https://security-tracker.debian.org/tracker/ghostscript https://security-tracker.debian.org/tracker/CVE-2019-14869 | 3.7.10 |
| CM-27299 | The protocol daemon bgpd crashes when a link/neighbor flaps if static routes pointing to Null0 are advertising through BGP.To work around this issue, reboot the switch, then remove the static routes or stop advertising these routes. | 3.7.9-3.7.10 |
| CM-27269 | The following Linux kernel security vulnerabilities do not affect Cumulus Linux in supported configurations: CVE-2018-12207 CVE-2019-0154 CVE-2019-0155 CVE-2019-11135 Several vulnerabilities have been discovered in the Linux kernel that may may to a privilege escalation, denial of service, or information leak.

For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | |
| CM-27243 | The length of the netlink message is not set properly for non-bridge family type messages. The same length is used for both bridge and non-bridge even though the bridge family type message has an extra attribute. This causes extra bytes to be left over in non-bridge family type netlink messages. | 3.7.10 |
| CM-27233 | If you change multiple BGP or BFD timers in the /etc/frr/frr.conf file and then reload FRR, a traceback is encountered and the change does not take effect. | 3.7.9-3.7.10 |
| CM-27193 | The l1-show command prints a traceback for switch ports that have sub-interfaces configured. There is no functional impact to traffic but the l1-show troubleshooting and validation command does not execute on switch ports that have VLAN sub-interfaces. | 3.7.10 |
| CM-27174 | The ospfd daemon might crash with the following kernel trace:2019-11-06T23:00:08.261749+09:00 cumulus ospfd[5339]: Assertion ‘node’ failed in file ospfd/ospf_packet.c, line 671, function ospf_write | 3.7.6-3.7.10 |
| CM-27096 | On the Edgecore AS6812 switch, you might see rare I2C errors. | 3.7.2-3.7.10 |
| CM-27025 | On the Mellanox switch, ACL lookups are performed for VLAN matches when no rules with UNTAGGED match are present. | 3.7.2-3.7.10 |
| CM-26996 | On the Mellanox switch with the Spectrum ASIC, the --set-burst parameter in an iptables rule does not take effect. | 3.7.10 |
| CM-26968 | When networking fails to start properly, an MLAG memory leak occurs, which might cause memory issues. | 3.7.9-3.7.10 |
| CM-26954 | In the default VRF, VRRP might crash and stay in an initialize state. As a result, VRRP multicast traffic is not generated. | 3.7.8-3.7.10 |
| CM-26947 | The following CVEs affect the OpenLDAP utilities: CVE-2019-13057 CVE-2019-13565 For the detailed security status, refer to the security tracker page at: https://security-tracker.debian.org/tracker/CVE-2019-13565 https://security-tracker.debian.org/tracker/CVE-2019-13057 Vulnerable versions: < 2.4.40+dfsg-1+deb8u5 Fixed versions: >= 2.4.40+dfsg-1+deb8u5 | |
| CM-26838 | You might experience a bgpd memory usage increase and significant update exchanges due to host moves between VTEPs. | 3.7.7-3.7.10 |
| CM-26829 | Frames received with a VLAN tag of 0 on an interface configured as a bridge port and forwarded to the CPU for processing might appear tagged with the native VLAN when viewed with tcpdump. | 3.7.8-3.7.10 |
| CM-26815 | If a router MAC address changes on a VTEP, other VTEPs might still point to the previous router MAC address. | 3.7.10 |
| CM-26769 | Setting ProtoDown on ports populated with SFP modules providing RJ-45 1000BASE-T interfaces does not cause the carrier to be dropped. The kernel shows carrier down; however, the remote device still shows a link. | 3.7.6-3.7.10 |
| CM-26691 | BGP is configured with soft reconfiguration-in for its peers, which is not working correctly and causes routes to have an unexpected label. As a result, transit traffic is not forwarded by the switch. | 3.7.7-3.7.10 |
| CM-26657 | When you install a large number of new rules with nonatomic mode enabled, there is a chance that you install more rules than the number of available slots in the slice, which results in the slice being completely wiped and reinstalled. This causes a large drop increase, including to cpu0, and might cause a major outage by dropping all BGP sessions. | 3.6.1-3.7.10 |
| CM-26525 | When an MLAG peerlink frequently alternates states between learning and blocking, an excessive number of TCP sessions might be created, which results in the following error display:OSError: [Errno 24] Too many open files | 3.6.2-3.7.10 |
| CM-26523 | Package: hostapd CVE ID: CVE-2019-13377 CVE-2019-16275 Two vulnerabilities were found in the WPA protocol implementation found in wpa_supplication (station) and hostapd (access point). CVE-2019-13377 A timing-based side-channel attack against WPA3’s Dragonfly handshake when using Brainpool curves could be used by an attacker to retrieve the password. CVE-2019-16275 Insufficient source address validation for some received Management frames in hostapd could lead to a denial of service for stations associated to an access point. An attacker in radio range of the access point could inject a specially constructed unauthenticated IEEE 802.11 frame to the access point to cause associated stations to be disconnected and require a reconnection to the network. Fixed version: 1:2.8.0-cl4u3 | 3.7.0-3.7.10 |
| CM-26450 | Cumulus Linux poed generates excessive debug log entries. These will be reduced in a future release. | 3.7.3-3.7.10 |
| CM-26448 | Traffic sent to the SVI IP address of a switch might be lost if all of the following conditions are met:
To workaround this issue, restart switchd. | 3.7.9-3.7.10 |
| CM-26437 | NCLU crashes when you run the net add interface storage-optimized pfc command because non-ascii quotes exist in the datapath.conf file.To work around this issue, manually edit the /usr/lib/python2.7/dist-packages/cumulus/__chip_config/mlx/datapath.conf file and replace the non-ascii single quotes with ascii single quotes (standard single quote on the keyboard). | 3.7.9-3.7.10 |
| CM-26372 | FRR crashes when adding an IPv6 neighbor with extended-nexthop capability. | 3.7.9-3.7.10 |
| CM-26308 | An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. | 3.7.8-3.7.10 |
| CM-26272 | On the Mellanox Spectrum switch, a route withdrawal might cause the associated next hop neighbor entry to be deleted in hardware but remain in the kernel. This can cause traffic going through the directly connected route to the removed neighbor entry to be forwarded to the CPU. | 3.7.6-3.7.10 |
| CM-26255 | On the Mellanox SN2700 switch, you cannot enable resilient hashing (RASH) and set the bucket size to 64 in the traffic.conf file. | 3.7.6-3.7.10 |
| CM-26252 | The following CVEs were announced that affect the ghostscript package: CVE ID : CVE-2019-14811 CVE-2019-14812 CVE-2019-14813 CVE-2019-14817 It was discovered that various procedures in Ghostscript, the GPL PostScript/PDF interpreter, do not properly restrict privileged calls, which could result in bypass of file system restrictions of the dSAFER sandbox. We recommend that you upgrade your ghostscript packages. For the detailed security status of ghostscript, refer to its security tracker page at: https://security-tracker.debian.org/tracker/ghostscript | 3.7.0-3.7.10 |
| CM-26217 | NCLU does not allow you to configure OSPF NSSAs. For example:cumulus@switch:~$ net add ospf area 0.0.0.1 nssa To work around this issue, use FRR instead. For example: switch# configure terminal | 3.7.7-3.7.10 |
| CM-26181 | ACL rules, such as the following, fail to install if you use swp+ (interfaces mentioned as wildcards).-A FORWARD -i swp+ -j LOG You can now install such rules with swp+. | 3.7.3-3.7.10 |
| CM-26179 | If a hostname contains utf-8 characters, the NCLU net show lldp command outputs the following error:ERROR: ‘ascii’ codec can’t encode character u’\xe9’ in position 3: ordinal not in range(128) | 3.7.7-3.7.10 |
| CM-26169 | Cumulus Linux does not map QinQ packets to VXLANs in a configuration with a VLAN-aware bridge and MLAG on the Trident3 platform. | 3.7.9-3.7.10 |
| CM-26158 | On the Mellanox switch, UFT profiles are unable to support the documented capacity for routes to addresses that are more than 64 bits in length. The listed capacities assume 64-bit destination IP addresses. | 3.7.8-3.7.10 |
| CM-26147 | On the EdgeCore AS4610 switch, the ping command fails unless you run the command with sudo.To work around this issue, run the following commands: cumulus@switch:~$ sudo setcap cap_net_raw+ep /usr/share/mgmt-vrf/bin/ping Run the following command to verify the workaround:
You should see the following output:

| CM-26146 | clagd memory consumption increases under certain unknown conditions. | 3.7.8-3.7.10 |
| CM-26082 | The following vulnerabilities are only applicable if qemu is installed from the repo mirror. It is not present in the base image by default, so base images without qemu installed are not vulnerable. CVE-2018-20815 CVE-2019-13164 CVE-2019-14378: Multiple security issues were discovered in QEMU, a fast processor emulator, which could result in denial of service, the execution of arbitrary code or bypass of ACLs.

| CM-25973 | After a remote VTEP peer link goes down, the tunnel destination IP address might be incorrect in hardware, which might cause loss of overlay communication between VTEPs. | 3.7.8-3.7.10 |
| CM-25955 | Lenovo switches do not send or receive LLDP on eth0 interfaces. | 3.7.7-3.7.10 |
| CM-25824 | NCLU restarts FRR when attempting to remove a BGP VRF stanza. This happens regardless of whether the VRF is valid/configured elsewhere on the switch or the removal is successful. To work around this issue, remove the stanza using vtysh. | 3.7.3-3.7.10 |
| CM-25747 | When transitioning from a down state to an up state due to peerlink failure and recovery, MLAG does not start the initDelay timer before trying to bring everything back up. | 3.7.7-3.7.10 |
| CM-25718 | IF-MIB::ifHCInOctets reports significantly lower values than reported by interface counters seen elsewhere. | 3.7.6-3.7.10 |
| CM-25704 | The following CVEs affect the linux package: CVE-2019-13272 It was discovered that the ptrace subsystem in the Linux kernel mishandles the management of the credentials of a process that wants to create a ptrace relationship, allowing a local user to obtain root privileges under certain scenarios. Cumulus Linux is not affected. For the detailed security status of linux please refer to its security tracker page at: https://security-tracker.debian.org/tracker/CVE-2019-13272 | |
| CM-25693 | After you issue the NCLU net del bgp vrf <vrf> autonomous-system <AS> command and commit the change, Cumulus Linux does not remove the configuration from the /etc/frr/frr.conf file or the net show config commands. | 3.7.3-3.7.10 |
| CM-25672 | snmpd fails because NCLU does not remove agentaddress @vrf lines when running the net add snmp-server listening-address all command. | 3.7.4-3.7.10 |
| CM-25640 | When you configure the switch to send an EAP request with the net add dot1x send-eap-request-id command, the switch ignores re-authentication attempts and does not send back an EAPol. | 3.7.6-3.7.10 |
| CM-25505 | In EVPN symmetric or centralized configurations with BGP peering over a peer link, VXLAN routed packets transiting an MLAG peer are dropped until the clagd init-delay timer expires during the bring-up sequence following a reboot.The problem is caused by a race condition when programming the anycast IP address (used to terminate VXLAN tunnels), where the hardware is programmed before the software by clagd.To work around this issue, configure the BGP path across the peer link to be less preferred. The example below uses AS path prepending and the MLAG switches are iBGP neighbors. However, other BGP configurations achieve the same result. In the /etc/frr/frr.conf file, make a new AS path access list and route map to apply BGP pre-pending of the local ASN one or more times. For example:
| 3.7.6-3.7.10 |
| CM-25447 | When you define a trap destination using @mgmt, snmpd indicates that the network is unreachable even though the IP address is reachable in the management VRF.To work around this issue, remove @mgmt vrf references in the /etc/snmp/snmpd.conf file, stop snmpd, then start snmpd manually in the management VRF with the systemctl start snmpd@mgmt command. | 3.7.6-3.7.10 |
| CM-25376 | When you generate a cl-support file, clagd.service prints log messages similar to the following:019-03-21T07:18:15.727581+00:00 leaf01 clagd[20912]: DumpThreadStacks - start 2019-03-21T07:18:15.728157+00:00 leaf01 clagd[20912]: #012thread: CollectSysInfo (140608446367488) 2019-03-21T07:18:15.735986+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 783, in __bootstrap 2019-03-21T07:18:15.736585+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 810, in __bootstrap_inner 2019-03-21T07:18:15.737045+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 763, in run 2019-03-21T07:18:15.737933+00:00 leaf01 clagd[20912]: file: /usr/sbin/clagd, line 930, in CollectSysInfoT 2019-03-21T07:18:15.739527+00:00 leaf01 clagd[20912]: file: /usr/sbin/clagd, line 187, in CollectSysInfo 2019-03-21T07:18:15.740540+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 621, in wait 2019-03-21T07:18:15.742293+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/dist-packages/clag/clagthread.py, line 48, in wait . . 2019-03-21T07:18:16.456061+00:00 leaf01 clagd[20912]: DumpThreadStacks - end | 3.7.6-3.7.10 |
| CM-25298 | The following CVEs were announced in a Debian Security Advisory that affects vim modelines. Package: vim and neovim CVE ID: CVE-2019-12735 Debian Bugs: 930020, 930024 getchar.c in Vim before 8.1.1365 and Neovim before 0.3.6 allows remote attackers to execute arbitrary OS commands via the :source! command in a modeline, as demonstrated by execute in Vim, and assert_fails or nvim_input in Neovim. For the detailed security status, refer to the security tracker page at: https://security-tracker.debian.org/tracker/CVE-2019-12735 https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-12735.html https://github.com/numirias/security/blob/master/doc/2019-06-04_ace-vim-neovim.md Cumulus Networks recommends that you disable modelines in the the vimrc file (set nomodeline) to use the securemodelines plugin or to disable modelineexpr (since patch 8.1.1366, Vim-only) to disallow expressions in modelines.To check if you have modelines enabled, open vim and enter: :set modeline? If vim returns nomodeline, you are not vulnerable. If you are vulnerable or you want to ensure your security with this issue, add these lines to your vimrc file:set modelines=0 set nomodeline modeline is enabled by default. Verify that you do not have any existing lines in .vimrc that set modelines or modeline. | 3.0.0-3.7.10 |

| CM-33008 | Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed. CVE-2020-19667 Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c CVE-2020-25665 The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. This could cause impact to reliability. CVE-2020-25674 WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. CVE-2020-27560 ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service. CVE-2020-27750 A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould trigger undefined behavior in the form of values outside the range of type unsigned char and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27760 In GammaImage() of /MagickCore/enhance.c, depending on the gamma value, it’s possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. CVE-2020-27763 A flaw was found in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27765 A flaw was found in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27773 A flaw was found in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-29599 ImageMagick mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.

| CM-30863 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.0.0-3.7.14 | |

| CM-27299 | The protocol daemon bgpd crashes when a link/neighbor flaps if static routes pointing to Null0 are advertising through BGP.To work around this issue, reboot the switch, then remove the static routes or stop advertising these routes. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-27295 | IPv6 table rules might affect forwarding. For example, if you create the following rule in the /etc/cumulus/acl/policy.d/03-sshd.rules file, the rule counter increments but IPv4 SSH traffic might be dropped.[ip6tables] | 3.7.2-3.7.11 | 3.7.12-3.7.14 |
| CM-27279 | When ECMP routes have both VXLAN (symmetric routing) and non-VXLAN paths, the non-VXLAN path is incorrectly installed in the RIB and FIB to point across VXLAN. The non-VXLAN next-hop will be installed as an offload entry in the neighbor table (ip neigh show) with a mac address of 00:00:00:00:00:00. | 3.7.3-3.7.14 | |
| CM-27243 | The length of the netlink message is not set properly for non-bridge family type messages. The same length is used for both bridge and non-bridge even though the bridge family type message has an extra attribute. This causes extra bytes to be left over in non-bridge family type netlink messages. | 3.7.10 | 3.7.11-3.7.14 |
| CM-27233 | If you change multiple BGP or BFD timers in the /etc/frr/frr.conf file and then reload FRR, a traceback is encountered and the change does not take effect. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-27193 | The l1-show command prints a traceback for switch ports that have sub-interfaces configured. There is no functional impact to traffic but the l1-show troubleshooting and validation command does not execute on switch ports that have VLAN sub-interfaces. | 3.7.10 | 3.7.11-3.7.14 |
| CM-27192 | If you use NCLU commands to add a non-MLAG bond, then add an MLAG configuration, the net commit command fails. However, a subsequent net commit command succeeds. | 3.7.10-3.7.14 | |
| CM-27174 | The ospfd daemon might crash with the following kernel trace:2019-11-06T23:00:08.261749+09:00 cumulus ospfd[5339]: Assertion ‘node’ failed in file ospfd/ospf_packet.c, line 671, function ospf_write | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-27173 | On the Trident3 switch, unicast ARP packets received on a VNI and forwarded to the CPU are not policed. | 3.7.10-3.7.13 | 3.7.14 |
| CM-27120 | When an interface flap occurs, numbered IPv6 BGP sessions might fail to establish. To work around this issue, run the ip -6 route flush cache <IPv6-address> command to flush the IPv6 route cache. | 3.7.9-3.7.11 | 3.7.12-3.7.14 |
| CM-27096 | On the Edgecore AS6812 switch, you might see rare I2C errors. | 3.7.2-3.7.10 | 3.7.11-3.7.14 |
| CM-27094 | On the Delta AG9032v1 switch, smonctl and sensors report inaccurate PSU current and power. | 3.5.0-3.7.14 | |
| CM-27025 | On the Mellanox switch, ACL lookups are performed for VLAN matches when no rules with UNTAGGED match are present. | 3.7.2-3.7.10 | 3.7.11-3.7.14 |
| CM-27018 | If you configure more than one VRR interface on an SVI interface, deleting one of the VRR addresses does not remove the interface/address. | 3.7.10-3.7.14 | |
| CM-26996 | On the Mellanox switch with the Spectrum ASIC, the --set-burst parameter in an iptables rule does not take effect. | 3.7.10 | 3.7.11-3.7.14 |
| CM-26968 | When networking fails to start properly, an MLAG memory leak occurs, which might cause memory issues. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26954 | In the default VRF, VRRP might crash and stay in an initialize state. As a result, VRRP multicast traffic is not generated. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26921 | If you delete an undefined bond, then add a bond slave, the net commit command fails. | 3.7.9-3.7.14 | |
| CM-26913 | FRR configuration commands for an SVI interface might have the \n misplaced in the output. For example:sudo sh -c “printf ‘interface 50\nvrf TEST description L3 routing interface\n’ » /etc/frr/frr.conf" should be: sudo sh -c “printf ‘interface 50 vrf TEST\ndescription L3 routing interface\n’ » /etc/frr/frr.conf" To work around this issue, configure the interface manually in the /etc/frr/frr.conf file. | 3.7.9-3.7.14 | |
| CM-26905 | When you update the hostname of a switch with the NCLU net add hostname <hostname> command, then run net commit, the lldpd service does not restart and other devices still see the old hostname.To work around this issue, run the sudo systemctl restart lldpd.service command. | 3.7.10-3.7.14 | |
| CM-26894 | The neighmgrd service does not ignore neighbors on reserved devices (lo and management devices). This issue is not seen when management VRF is enabled. | 3.7.8-3.7.11 | 3.7.12-3.7.14 |
| CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-3.7.14 | |
| CM-26838 | You might experience a bgpd memory usage increase and significant update exchanges due to host moves between VTEPs. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26829 | Frames received with a VLAN tag of 0 on an interface configured as a bridge port and forwarded to the CPU for processing might appear tagged with the native VLAN when viewed with tcpdump. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26815 | If a router MAC address changes on a VTEP, other VTEPs might still point to the previous router MAC address. | 3.7.10 | 3.7.11-3.7.14 |
| CM-26769 | Setting ProtoDown on ports populated with SFP modules providing RJ-45 1000BASE-T interfaces does not cause the carrier to be dropped. The kernel shows carrier down; however, the remote device still shows a link. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26691 | BGP is configured with soft reconfiguration-in for its peers, which is not working correctly and causes routes to have an unexpected label. As a result, transit traffic is not forwarded by the switch. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26657 | When you install a large number of new rules with nonatomic mode enabled, there is a chance that you install more rules than the number of available slots in the slice, which results in the slice being completely wiped and reinstalled. This causes a large drop increase, including to cpu0, and might cause a major outage by dropping all BGP sessions. | 3.6.1-3.7.10 | 3.7.11-3.7.14 |
| CM-26655 | If you reconfigure an NTP server with NCLU using different trailing options after the IP address (such as iburst), an invalid configuration is added to the /etc/ntp.conf file. For example:net add time ntp server 1.2.3.4 iburst If you need to alter existing server configurations, first remove the server, commit, then re-add the server with any trailing options. | 3.7.9-3.7.14 | |
| CM-26599 | Auto-negotiation does not work with the QSFP28 cables and a remote system operating at 10G. Attempting to enable auto-negotiation with ethtool -s swp<#> autoneg on returns Operation not supported.To work around this issue, do not use auto-negotiation and set the local port speed to 10G. | 3.7.9-3.7.14 | |
| CM-26595 | The NCLU net show lldp command displays the speed of a ganged port group as the speed of one of the individual links, rather than the sum of their speeds. | 3.7.9-3.7.14 | |
| CM-26525 | When an MLAG peerlink frequently alternates states between learning and blocking, an excessive number of TCP sessions might be created, which results in the following error display:OSError: [Errno 24] Too many open files | 3.6.2-3.7.10 | 3.7.11-3.7.14 |
| CM-26523 | Package: hostapd CVE ID: CVE-2019-13377 CVE-2019-16275 Two vulnerabilities were found in the WPA protocol implementation found in wpa_supplication (station) and hostapd (access point). CVE-2019-13377 A timing-based side-channel attack against WPA3’s Dragonfly handshake when using Brainpool curves could be used by an attacker to retrieve the password. CVE-2019-16275 Insufficient source address validation for some received Management frames in hostapd could lead to a denial of service for stations associated to an access point. An attacker in radio range of the access point could inject a specially constructed unauthenticated IEEE 802.11 frame to the access point to cause associated stations to be disconnected and require a reconnection to the network. Fixed version: 1:2.8.0-cl4u3 | 3.7.0-3.7.10 | 3.7.11-3.7.14 |
| CM-26516 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.14 | |
| CM-26463 | The following CVEs affect the linux kernel package: CVE-2019-14821 CVE-2019-14835 CVE-2019-15117 CVE-2019-15118 CVE-2019-15902 Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. For the detailed security status of linux, refer to its security tracker page at: https://security-tracker.debian.org/tracker/linux | 3.7.10-3.7.14 | |
| CM-26450 | Cumulus Linux poed generates excessive debug log entries. These will be reduced in a future release. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-26448 | Traffic sent to the SVI IP address of a switch might be lost if all of the following conditions are met:
To workaround this issue, restart switchd. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26437 | NCLU crashes when you run the net add interface storage-optimized pfc command because non-ascii quotes exist in the datapath.conf file.To work around this issue, manually edit the /usr/lib/python2.7/dist-packages/cumulus/__chip_config/mlx/datapath.conf file and replace the non-ascii single quotes with ascii single quotes (standard single quote on the keyboard). | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26423 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.14 | |
| CM-26412 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.14 | |
| CM-26372 | FRR crashes when adding an IPv6 neighbor with extended-nexthop capability. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26351 | After you remove a subinterface, the BGP session stays in a Connect state. | 3.7.8-3.7.11 | 3.7.12-3.7.14 |
| CM-26308 | An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26288 | On the Mellanox switch, static VXLAN tunnels incorrectly allow traffic from any remote tunnel IP address. | 3.7.8-3.7.14 | |
| CM-26272 | On the Mellanox Spectrum switch, a route withdrawal might cause the associated next hop neighbor entry to be deleted in hardware but remain in the kernel. This can cause traffic going through the directly connected route to the removed neighbor entry to be forwarded to the CPU. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26256 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.14 | |
| CM-26255 | On the Mellanox SN2700 switch, you cannot enable resilient hashing (RASH) and set the bucket size to 64 in the traffic.conf file. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26252 | The following CVEs were announced that affect the ghostscript package: CVE ID : CVE-2019-14811 CVE-2019-14812 CVE-2019-14813 CVE-2019-14817 It was discovered that various procedures in Ghostscript, the GPL PostScript/PDF interpreter, do not properly restrict privileged calls, which could result in bypass of file system restrictions of the dSAFER sandbox. We recommend that you upgrade your ghostscript packages. For the detailed security status of ghostscript, refer to its security tracker page at: https://security-tracker.debian.org/tracker/ghostscript | 3.7.0-3.7.10 | 3.7.11-3.7.14 |
| CM-26241 | On the Dell S5248F-ON switch, smond might generate syslog messages indicating that the fan input RPM is lower than the normal low speed of 2500 RPM. Speeds as low as 1700 RPM are acceptable in normal thermal environments; therefore, you can ignore these messages. | 3.7.6-3.7.11 | 3.7.12-3.7.14 |
| CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.14 | |
| CM-26225 | On the EdgeCore AS5712, AS6712, AS5812 and AS6812 switch, support for multiple PSU types results in log messages similar to the following:2019-09-05T05:15:17.246597+00:00 hp-6712-03 decode-syseeprom: Unable to find eeprom at /sys/bus/i2c/devices/11-0050/eeprom for psu2 | 3.7.9-3.7.12 | 3.7.13-3.7.14 |
| CM-26217 | NCLU does not allow you to configure OSPF NSSAs. For example:cumulus@switch:~$ net add ospf area 0.0.0.1 nssa To work around this issue, use FRR instead. For example: switch# configure terminal | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26181 | ACL rules, such as the following, fail to install if you use swp+ (interfaces mentioned as wildcards).-A FORWARD -i swp+ -j LOG You can now install such rules with swp+. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-26179 | If a hostname contains utf-8 characters, the NCLU net show lldp command outputs the following error:ERROR: ‘ascii’ codec can’t encode character u’\xe9’ in position 3: ordinal not in range(128) | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26169 | Cumulus Linux does not map QinQ packets to VXLANs in a configuration with a VLAN-aware bridge and MLAG on the Trident3 platform. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26158 | On the Mellanox switch, UFT profiles are unable to support the documented capacity for routes to addresses that are more than 64 bits in length. The listed capacities assume 64-bit destination IP addresses. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26147 | On the EdgeCore AS4610 switch, the ping command fails unless you run the command with sudo.To work around this issue, run the following commands: cumulus@switch:~$ sudo setcap cap_net_raw+ep /usr/share/mgmt-vrf/bin/ping Run the following command to verify the workaround:
You should see the following output:
| 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26146 | clagd memory consumption increases under certain unknown conditions. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26138 | You cannot specify a source and destination MAC address in an ERSPAN ebtables rule. For example, the following rule does not work:-A FORWARD -i swp5 -s 00:25:90:b2:bd:9d -d 50:6b:4b:96:c4:04 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:-A FORWARD -i vni10 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.14 | |
| CM-26136 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.14 | |
| CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.14 | |
| CM-26082 | The following vulnerabilities are only applicable if qemu is installed from the repo mirror. It is not present in the base image by default, so base images without qemu installed are not vulnerable. CVE-2018-20815 CVE-2019-13164 CVE-2019-14378: Multiple security issues were discovered in QEMU, a fast processor emulator, which could result in denial of service, the execution of arbitrary code or bypass of ACLs. Cumulus Linux 3: >= 2.1+dfsg-12+deb8u12 fixed. https://security-tracker.debian.org/tracker/qemu https://security-tracker.debian.org/tracker/CVE-2018-20815 https://security-tracker.debian.org/tracker/CVE-2019-13164 https://security-tracker.debian.org/tracker/CVE-2019-14378 | 3.7.10 | 3.7.11-3.7.14 |
| CM-26024 | On switches with the Spectrum ASIC, the underlay hashes VXLAN packets for a given overlay flow randomly. To work around this issue, configure the ECMP hash seed to the same value on the EVPN egress leaf switches. | 3.7.7-3.7.12 | 3.7.13-3.7.14 |
| CM-25973 | After a remote VTEP peer link goes down, the tunnel destination IP address might be incorrect in hardware, which might cause loss of overlay communication between VTEPs. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-25955 | Lenovo switches do not send or receive LLDP on eth0 interfaces. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-3.7.14 | |
| CM-25890 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.14 | |
| CM-25859 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.14 | |
| CM-25824 | NCLU restarts FRR when attempting to remove a BGP VRF stanza. This happens regardless of whether the VRF is valid/configured elsewhere on the switch or the removal is successful. To work around this issue, remove the stanza using vtysh. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-25815 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.14 | |
| CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:ifdown vlan123 ; sleep 2 ; ifup vlan123 You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.14 | |
| CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.14 | |
| CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-3.7.14 | |
| CM-25747 | When transitioning from a down state to an up state due to peerlink failure and recovery, MLAG does not start the initDelay timer before trying to bring everything back up. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-25740 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:cumulus@switch:~$ net add bridge mybridge vlan-protocol 802.1ad | 3.7.6-3.7.14 | |
| CM-25718 | IF-MIB::ifHCInOctets reports significantly lower values than reported by interface counters seen elsewhere. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25694 | If a packet is policed by ebtables, it does not increment an ACL drop on the ingress interface. Instead, it increments the TDBGC3/6 drop counter to the CPU. | 3.7.6-3.7.14 | |
| CM-25693 | After you issue the NCLU net del bgp vrf <vrf> autonomous-system <AS> command and commit the change, Cumulus Linux does not remove the configuration from the /etc/frr/frr.conf file or the net show config commands. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-25672 | snmpd fails because NCLU does not remove agentaddress @vrf lines when running the net add snmp-server listening-address all command. | 3.7.4-3.7.10 | 3.7.11-3.7.14 |
| CM-25665 | On the Broadcom Trident 3 switch, VXLAN encapsulated packets are dropped on the ingress port (tagged layer 2 port) during transit forwarding (the local switch does not terminate the VXLAN tunnel). An example of where this two-layer VXLAN inside VXLAN encapsulation might occur:
| 3.7.5-3.7.11 | 3.7.12-3.7.14 |
| CM-25641 | If the BMC operating system fails to respond to IPMI, you see a traceback in bmcd and all the sensors might report ABSENT devices in smonctl.To work around this issue, power cycle the switch. | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-25640 | When you configure the switch to send an EAP request with the net add dot1x send-eap-request-id command, the switch ignores re-authentication attempts and does not send back an EAPol. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25505 | In EVPN symmetric or centralized configurations with BGP peering over a peer link, VXLAN routed packets transiting an MLAG peer are dropped until the clagd init-delay timer expires during the bring-up sequence following a reboot.The problem is caused by a race condition when programming the anycast IP address (used to terminate VXLAN tunnels), where the hardware is programmed before the software by clagd.To work around this issue, configure the BGP path across the peer link to be less preferred. The example below uses AS path prepending and the MLAG switches are iBGP neighbors. However, other BGP configurations achieve the same result. In the /etc/frr/frr.conf file, make a new AS path access list and route map to apply BGP pre-pending of the local ASN one or more times. For example:

| CM-25447 | When you define a trap destination using @mgmt, snmpd indicates that the network is unreachable even though the IP address is reachable in the management VRF.To work around this issue, remove @mgmt vrf references in the /etc/snmp/snmpd.conf file, stop snmpd, then start snmpd manually in the management VRF with the systemctl start snmpd@mgmt command. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.14 | |
| CM-25400 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.14 | |
| CM-25397 | When first creating a bond and enslaving an interface, NCLU hides some of the bridge command suggestions, although they are still accepted. | 3.7.3-3.7.14 | |
| CM-25376 | When you generate a cl-support file, clagd.service prints log messages similar to the following:019-03-21T07:18:15.727581+00:00 leaf01 clagd[20912]: DumpThreadStacks - start 2019-03-21T07:18:15.728157+00:00 leaf01 clagd[20912]: #012thread: CollectSysInfo (140608446367488) 2019-03-21T07:18:15.735986+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 783, in __bootstrap 2019-03-21T07:18:15.736585+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 810, in __bootstrap_inner 2019-03-21T07:18:15.737045+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 763, in run 2019-03-21T07:18:15.737933+00:00 leaf01 clagd[20912]: file: /usr/sbin/clagd, line 930, in CollectSysInfoT 2019-03-21T07:18:15.739527+00:00 leaf01 clagd[20912]: file: /usr/sbin/clagd, line 187, in CollectSysInfo 2019-03-21T07:18:15.740540+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/threading.py, line 621, in wait 2019-03-21T07:18:15.742293+00:00 leaf01 clagd[20912]: file: /usr/lib/python2.7/dist-packages/clag/clagthread.py, line 48, in wait . . 2019-03-21T07:18:16.456061+00:00 leaf01 clagd[20912]: DumpThreadStacks - end | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25298 | The following CVEs were announced in a Debian Security Advisory that affects vim modelines. Package: vim and neovim CVE ID: CVE-2019-12735 Debian Bugs: 930020, 930024 getchar.c in Vim before 8.1.1365 and Neovim before 0.3.6 allows remote attackers to execute arbitrary OS commands via the :source! command in a modeline, as demonstrated by execute in Vim, and assert_fails or nvim_input in Neovim. For the detailed security status, refer to the security tracker page at: https://security-tracker.debian.org/tracker/CVE-2019-12735 https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-12735.html https://github.com/numirias/security/blob/master/doc/2019-06-04_ace-vim-neovim.md Cumulus Networks recommends that you disable modelines in the the vimrc file (set nomodeline) to use the securemodelines plugin or to disable modelineexpr (since patch 8.1.1366, Vim-only) to disallow expressions in modelines.To check if you have modelines enabled, open vim and enter: :set modeline? If vim returns nomodeline, you are not vulnerable. If you are vulnerable or you want to ensure your security with this issue, add these lines to your vimrc file:set modelines=0 set nomodeline modeline is enabled by default. Verify that you do not have any existing lines in .vimrc that set modelines or modeline. | 3.0.0-3.7.10 | 3.7.11-3.7.14 |
| CM-25001 | The following CVEs were announced in Debian Security Advisory DSA-444-1, DSA-4447-1 and affect the linux kernel and microcode. Package: linux CVE ID: CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091 Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. Contact your hardware ndor for microcode uppdates. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver. Fixed in version 4.19.76-1+cl4u1 | 3.0.0-3.7.14 | |
| CM-24894 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.14 | |
| CM-24799 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.14 | |
| CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-3.7.14 | |
| CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.14 | |
| CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.14 | |
| CM-24652 | In an EVPN environment, the centralized MAC address is not installed on the MLAG pair because Cumulus Linux does not perform an SVI MAC check per VLAN. This issue does not affect a pure distributed routing (symmetric or asymmetric) environment or a pure centralized routing environment. | 3.7.0-3.7.14 | |
| CM-24618 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:ERROR: No closing quotation See /var/log/netd.log for more details. | 3.6.1-3.7.14 | |
| CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.14 | |
| CM-24435 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect: net add routing route-map Proxy-ARP permit 25 match interface swp9-10 These commands are correct: net add routing route-map Proxy-ARP permit 25 match interface swp9 net add routing route-map Proxy-ARP permit 30 match interface swp10 | 3.7.2-3.7.14 | |
| CM-24426 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf <name> command just displays
Tab completion for the net add vrf <name> ip address <address> command works correctly. | 3.7.4-3.7.14 | |
| CM-24379 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.14 | |
| CM-24343 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.14 | |
| CM-24332 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.14 | |
| CM-24272 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface br0.100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# vrrp 1 advertisement-interval switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24271 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface vlan100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24270 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface swp4 switch(config-if)# vrrp 1 version 2 switch(config-if)# no vrrp 1 preempt switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24262 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto <iface> lines exist. | 3.7.3-3.7.14 | |
| CM-24241 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:cumulus@switch:~$ net del bgp neighbor fabric peer-group ‘router bgp 65001’ configuration does not have ‘neighbor fabric peer-group’ | 3.7.2-3.7.14 | |
| CM-24222 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.14 | |
| CM-24035 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.14 | |
| CM-23825 | The net add interface <interface> ptm-enable command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.14 | |
| CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev <interface> command. | 3.7.0-3.7.14 | |
| CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.14 | |
| CM-23665 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan <layer3-vni> bridge access <vlan>. This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.14 | |
| CM-23661 | On the Mellanox switch, when you configure a GRE tunnel, the traffic behind the local tunnel endpoint destined through the GRE tunnel is software-forwarded. | 3.7.2-3.7.14 | |
| CM-23651 | In an EVPN symmetric routing configuration, when an IP address is frozen, kernel neighbor table information and kernel VRF routing table information about the frozen IP address might be out-of-sync. | 3.7.3-3.7.14 | |
| CM-23584 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.14 | |
| CM-23570 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.14 | |
| CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.14 | |
| CM-23418 | For QSFP modules, the sudo ifdown command does not disable the Tx laser. | 3.7.2-3.7.14 | |
| CM-23417 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.14 | |
| CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.6.2-3.7.14 | |
| CM-23125 | The OpenSSL package on Cumulus Linux 3.x has a vulnerability similar to CVE-2018-0734. (The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key). According to Debian upstream, this version “is not vulnerable [to CVE-2018-0734 exactly]. Nevertheless, there is a bug fix that futher reduces the amount of leaked timing information. It got no CVE on its own and introduced this vulnerability.“ Vulnerable on CL3: 1.0.1t-1+deb8u12 | 3.0.0-3.7.14 | |
| CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.14 | |
| CM-23075 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:2018-11-10T23:35:30.992370-08:00 Dev dhcrelay: Listening on LPF/vlan.101/a0:00:00:00:00:51 2018-11-10T23:35:30.993472-08:00 Dev dhcrelay: Sending on LPF/vlan.101/a0:00:00:00:00:51 Eventually the dhcrelay service stops. | 3.7.1-3.7.14 | |
| CM-23021 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.14 | |
| CM-23016 | When FRR restarts, snmp<span class="error">[err]</span> dev/kmem: Permission denied error messages are recorded in the log file and SNMPd might crash periodically. | 3.7.5-3.7.10 | 3.7.11-3.7.14 |
| CM-23004 | The local fallback account authenticates using the local password when the RADIUS or TACACS service is up. The expected behavior is for this to fail and only succeed when the RADIUS OR TACACS server fails to respond. | 3.7.1-3.7.14 | |
| CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.6.0-3.7.14 | |
| CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.14 | |
| CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.5.2-3.7.14 | |
| CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.6.2-3.7.14 | |
| CM-22605 | On a Dell S4048 switch, when you set the eth0 speed to 100, either with NCLU or by editing the /etc/network/interfaces file, the igb driver crashes, which brings down eth0.To work around this issue:
| 3.5.3-3.7.10 | 3.7.11-3.7.14 |
| CM-22591 | CVE-2018-5391 (FragmentSmack) is a network vulnerability where an attacker can trigger time and calculation expensive fragment reassembly with specially crafted packets, leading to a denial of service. On a Cumulus Linux switch, the impact is limited to control plane and management plane traffic. Any control plane traffic coming in the front panel ports will be limited by existing policer ACLs. To work around this issue, create a file called /etc/sysctl.d/ip.conf and add these settings:net.ipv4.ipfrag_low_thresh = 196608 | 3.7.0-3.7.11 | 3.7.12-3.7.14 |
| CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.6.0-3.7.14 | |
| CM-22554 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 3.6.2-3.7.14 | |
| CM-22538 | When deleting an interface using NCLU, if the /etc/network/interfaces alias is different than the /etc/frr/frr.conf description, the net commit command returns the following error:/etc/frr/daemons was modified by another user. Despite this error, the change is made and the description is removed from the frr.conf file. | 3.6.2-3.7.10 | 3.7.11-3.7.14 |
| CM-22386 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.14 | |
| CM-22301 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.A $INGRESS_CHAIN –in-interface $INGRESS_INTF -m addrtype –dst-type IPROUTER -j POLICE –set-mode pkt –set-rate 400 –set-burst 100 These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 3.6.1-3.7.14 | |
| CM-22287 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 3.6.2-3.7.14 | |
| CM-22277 | On the Broadcom switch with the Trident3 ASIC, the ECN-CE bit is set by default on transit traffic. This might result in hosts adjusting traffic behavior if they are configured for the ECN feature. In Cumulus Linux 3.7.11, the default behavior changed; the ECN-CE bit is no longer set by default on transit traffic. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-22274 | To ease interoperation with non-Cumulus devices, it is possible to configure the route-target import and export values under the layer 2 VNI EVPN configuration. The same configuration does not work for both layer 2 VNI and layer 3 VNIs. Set the EVPN address-family within the VNI context when configuring the route-target in the layer 2 VNI. Set the EVPN address-family without the VNI context when configuring the route-target in the layer 3 VNI. | 3.6.0-3.7.14 | |
| CM-22252 | On the Edgecore OMP-800, there is no Power Supply information from the sensor or from smonctl. The platform driver has support for the PSUs but this was not added to the sensors infrastructure.This is a known limitation on the OMP-800 platform. | 3.6.2-3.7.14 | |
| CM-22228 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.14 | |
| CM-22205 | If a user is in vtysh when FRR is restarted, the running configuration in that vtysh session shows empty. | 3.6.2-3.7.14 | |
| CM-22138 | When you run the NCLU net show system command or the NetQ netq inventory command on the Edgecore OMP-800 switch, the output does not show any port or chip information. | 3.6.2-3.7.14 | |
| CM-22041 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.4.3-3.7.14 | |
| CM-22020 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.14 | |
| CM-21898 | On a Trident3 switch, IGMP packets are not policed by the police rule in the 00control ACL file. The packets are policed by the catchall policer in the 99control ACL file instead.-A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100To work around this issue, let the CPU bound IGMP packet hit the following rule and change the policer rate to a desired value for IGMP packets: -A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100Typically, the destination MAC address 01:00:5e:xx:xx:xx is used only for PIM/IGMP control and data stream packets. However, this workaround cannot handle data stream multicast packets that are not TCP/UDP; this is not typically done. | 3.6.2-3.7.12 | 3.7.13-3.7.14 |
| CM-21785 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 3.6.2-3.7.14 | |
| CM-21769 | On the Mellanox switch, GRE tunneling does not work if the tunnel source is configured on an SVI interface. If the tunnel source is configured on a physical switch port, then tunneling works as expected. | 3.6.1-3.7.13 | 3.7.14 |
| CM-21678 | On a Dell switch with a Maverick ASIC, NetQ might receive false alerts like the following via PagerDuty: cumulus@switch:~$ netq show sensors temp changes | grep absent | grep -v psu P2Leaf01 temp9 networking asic die temp sensor absent 43 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 47 105 100 5 Unable to read temp4_highest Add 9d:23h:26m:6s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to read temp4_highest Add 14d:22h:46m:45s This message might occur as a result of a timeout at the hardware level, or the switch might be reporting a failure to get a response. | 3.5.3-3.7.14 | |
| CM-21667 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 3.6.1-3.7.14 | |
| CM-21379 | If a primary route becomes unavailable (for example, you run ifdown on the switch port), the backup route remains inactive and is not installed into FIB.To work around this issue, configure routes as ECMP: cumulus@switch:~$ net del routing route 4.1.1.0/24 1.1.1.1 10 cumulus@switch:~$ net add routing route 4.1.1.0/24 1.1.1.1 cumulus@switch:~$ net commit | 3.5.3-3.7.14 | |
| CM-21373 | Debian issued the following security advisory, DSA-4231-1, which affects the libgcrypt20 package. This advisory applies only to the the Debian Stretch release. Debian Jessie, upon which Cumulus Linux 3.0 - 3.6.2 is based, is vulnerable. CVE-2018-0495 It was discovered that Libgcrypt is prone to a local side-channel attack allowing recovery of ECDSA private keys. For the stable distribution (stretch), this problem has been fixed in version 1.7.6-2+deb9u3. We recommend that you upgrade your libgcrypt20 packages. For the detailed security status of libgcrypt20, refer to its security tracker page at: https://security-tracker.debian.org/tracker/libgcrypt20 | 3.6.2-3.7.10 | 3.7.11-3.7.14 |
| CM-21332 | When two VLAN subinterfaces are bridged to each other in a traditional mode bridge, switchd doesn’t assign a gport to the subinterface, even though a gport is expected for each VLAN subinterface.To work around this issue, you can do one of two things:
| 3.5.3-3.7.14 | |
| CM-21278 | The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. | 3.5.3-3.7.10 | 3.7.11-3.7.14 |
| CM-21058 | The advertised routes list may be empty for an EVPN peering even though the remote switch reports received routes. | 3.6.0-3.7.14 | |
| CM-21055 | On the Mellanox switch, the destination MAC address of ERSPAN GRE packets is set to all zeros; therefore, the first transit switch might drop packets. | 3.6.0-3.7.13 | 3.7.14 |
| CM-20813 | Span rules matching the out-interface as a bond do not mirror packets. | 3.6.0-3.7.14 | |
| CM-20693 | In NCLU, you can only set the community number in a route map. You cannot set other community options such as no-export, no-advertise, or additive.This is a known limitation in network-docopt and is documented in the Cumulus Linux user guide. | 3.5.1-3.7.14 | |
| CM-20534 | The default BGP instance must be provisioned and always exist for proper operation of dynamic leaking of routes between VRFs. | 3.7.0-3.7.10 | 3.7.11-3.7.14 |
| CM-20508 | The Cumulus-Resource-Query-MIB defines the ability to gather buffer utilization status but when these objects are polled, they return nothing. | 3.5.3-3.7.14 | |
| CM-20480 | The python-crypto package, which is not installed by default on Cumulus Linux, but is present in the repository to be installed, has the following security vulnerability in the version available for Cumulus Linux 3.x: CVE-2018-6594: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto’s ElGamal implementation. More information at https://security-tracker.debian.org/tracker/CVE-2018-6594 . | 3.0.0-3.7.14 | |
| CM-20132 | On Trident2 switches running 802.3x regular link pause, pause frames are accounted in HwIfInDiscards counters and are dropped instead of processed. | 3.5.2-3.7.10 | 3.7.11-3.7.14 |
| CM-20033 | The VLAN interface stays up even though the physical link carrying the VLAN is admin or carrier down. | 3.5.2-3.7.14 | |
| CM-19788 | If you configure a VLAN under a VLAN-aware bridge and create a subinterface of the same VLAN on one of the bridge ports, the bridge and interface compete for the same VLAN and if the interface is flapped, it stops working. Correcting the configuration and running the ifreload command does not resolve the conflict.To work around this issue, correct the bridge VIDs and restart switchd or delete the subinterface. | 3.5.0-3.7.14 | |
| CM-19724 | PIM and MSDP entries are set to the internal COS value of 6 so they are grouped together with the bulk traffic priority group in the default traffic.conf file. However, PIM, IGMP, and MSDP are considered control-plane and should be set to the internal COS value of 7. | 3.5.2-3.7.14 | |
| CM-19454 | When you use NCLU to bring a bond admin down (net add bond <bond> link down), the bond interface goes into admin down state but the switch ports enslaved to the bond remain UP. If you are using bond-lacp-bypass-allow or balance-xor mode, the host might continue to send traffic. This traffic will be dropped because although the bond slaves are UP, they are not members of the bridge.To work around this issue, use the sudo ifdown <bondname> command. | 3.5.0-3.7.14 | |
| CM-19006 | On the Broadcom Trident II+, Trident 3, and Maverick based switch, in an external VXLAN routing environment, when a lookup is done on the external-facing switch (exit/border leaf) after VXLAN decapsulation, the switch does not rewrite the MAC addresses and TTL; for through traffic, packets are dropped by the next hop instead of correctly routing from a VXLAN overlay network into a non-VXLAN external network (for example, to the Internet). This applies to all forms of VXLAN routing (centralized, asymmetric and symmetric) and affects all traffic from VXLAN overlay hosts that need to be routed after VXLAN decapsulation on an exit/border leaf, including:
For example, if the expected interface configuration is: auto swp3.2001 iface swp3.2001 vrf vrf1 address 45.0.0.2/24 # where swp3 is the external facing port and swp3.2001 is the VLAN subinterface auto bridge iface bridge bridge-vlan-aware yes bridge ports vx-4001 bridge-vids 4001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 Modify the configuration as follows: auto swp3 iface swp3 bridge-access 2001 # associate the port (swp3) with bridge 2001 auto bridge iface bridge bridge-vlan-aware yes bridge ports swp3 vx-4001 vx-16000000 bridge-vids 4001 2001 # where vx-4001 is the existing VNI and vx-16000000 is a new temporary VNI # this is now bridging the port (swp3), the VNI (vx-4001), # and the new temporary VNI (vx-16000000) # the bridge VLAN IDs are now 4001 and 2001 auto vlan2001 iface vlan2001 vlan-id 2001 vrf vrf1 address 45.0.0.2/24 vlan-raw-device bridge # create a VLAN 2001 with the associated VRF and IP address auto vx-16000000 iface vx-16000000 vxlan-id 16000000 bridge-access 2001 <… usual vxlan config …> # associate the temporary VNI (vx-16000000) with bridge 2001 auto vx-4001 iface vx-4001 vxlan-id 4001 <… usual vxlan config …> bridge-access 4001 # where vnid 4001 represents the L3 VNI auto vlan4001 iface vlan4001 vlan-id 4001 vlan-raw-device bridge vrf vrf1 If an MLAG pair is used instead of a single exit/border leaf, the same temporary VNIs should be added on both switches of the MLAG pair. on the Broadcom Trident 3 switch. Note: This issue still exists on the Broadcom Trident II+ and Maverick-based switch. | 3.5.0-3.7.14 | |
| CM-18727 | On the Mellanox SN-2100 switch, unicast packets are counted in multicast queue counters. | 3.4.3-3.7.10 | 3.7.11-3.7.14 |
| CM-17934 | FRR tracks interface speed based on the value it learns from the Linux kernel for that interface. If the interface speed changes, FRR does not update its interface speed cache. This can lead to issues for routing protocols that derive metrics from interface speed as the cost can become out of sync with the interface speed. To work around this issue, manually define the routing protocol metric for these interfaces or restart FRR. | 3.7.6-3.7.14 | |
| CM-17557 | When sFlow is enabled, some sampled packets, such as IPMC, are forwarded twice (in the ASIC and then again through the kernel networking stack). | 3.4.0-3.7.14 | |
| CM-17494 | In certain cases, a peer device sends an ARP request from a source IP address that is not on the connected subnet and the switch creates a STALE neighbor entry. Eventually, the switch attempts to keep the entry fresh and sends ARP requests to the host. If the host responds, the switch has REACHABLE neighbor entries for hosts that are not on the connected subnet. To work around this issue, change the value of arp_ignore to 2. See Address Resolution Protocol in the Cumulus Linux user guide for more information. | 3.3.2-3.7.14 | |
| CM-16855 | If a two nodes on both sides of a link change from auto-negotiation off to auto-negotiation on for both sides during a short interval (around one second), the link might start flapping or stay down.To work around this issue and stop the flapping, turn the link down on the switch with the command ifdown swpX, wait a few seconds, then bring the link back up with the command ifup swpX. Repeat this on the other side if necessary. | 3.3.2-3.7.14 | |
| CM-16571 | NCLU cannot manage rsyslog to addresses routed via a VRF. In Cumulus Linux 4.0.0 and later, management VRF is enabled by default. To work around this issue, update the /etc/network/interfaces file to disable management VRF. | 3.4.3-3.7.14 | |
| CM-16461 | After booting a Cumulus VX virtual machine running the VMware OVA image, sometimes messages from sensors appear, indicating that the “Avg state” is critical, with all values displayed as 100.0. A cl-support is generated. | 3.4.2-3.7.14 | |
| CM-15812 | Multicast forwarding fails for IP addresses whose DMAC overlaps with reserved DIPs. | 3.2.1-3.7.14 | |
| CM-15601 | On a Mellanox switch in an MLAG configuration, routed packets that arrive on one switch to be forwarded to a destination MAC across the peer link are dropped due to MLAG loop prevention. This affects both routed unicast and multicast packets.To work around this issue, modify the routing design or policy such that routes do not have a next hop of an MLAG peer switch that traverses the MLAG peer link. | 3.6.2-3.7.13 | 3.7.14 |
| CM-15278 | During a link flap test, you might occasionally see a message similar to: warning: swp6: netlink: cannot set link swp6 down: <span class="error">[Errno 98]</span> Address already in use. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-15094 | Counter samples for an 80G bond (2 x 40G) exported from the switch show an interface speed (ifSpeed) of 14.464Gbps. | 3.2.0-3.7.14 | |
| CM-13316 | When you try to remove a VNI from a bridge using a regex match, the VNI is added back when you run the ifreload -a command. | 3.1.1-3.7.10 | 3.7.11-3.7.14 |

| CM-33008 | Several security vulnerabilities were found in ImageMagick, a suite of image manipulation programs. An attacker could cause denial of service and execution of arbitrary code when a crafted image file is processed. CVE-2020-19667 Stack-based buffer overflow and unconditional jump in ReadXPMImage in coders/xpm.c CVE-2020-25665 The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. This could cause impact to reliability. CVE-2020-25674 WriteOnePNGImage() from coders/png.c (the PNG coder) has a for loop with an improper exit condition that can allow an out-of-bounds READ via heap-buffer-overflow. This occurs because it is possible for the colormap to have less than 256 valid values but the loop condition will loop 256 times, attempting to pass invalid colormap data to the event logger. CVE-2020-27560 ImageMagick allows Division by Zero in OptimizeLayerFrames in MagickCore/layer.c, which may cause a denial of service. CVE-2020-27750 A flaw was found in MagickCore/colorspace-private.h and MagickCore/quantum.h. An attacker who submits a crafted file that is processedcould trigger undefined behavior in the form of values outside the range of type unsigned char and math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27760 In GammaImage() of /MagickCore/enhance.c, depending on the gamma value, it’s possible to trigger a divide-by-zero condition when a crafted input file is processed by ImageMagick. This could lead to an impact to application availability. CVE-2020-27763 A flaw was found in MagickCore/resize.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27765 A flaw was found in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-27773 A flaw was found in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. CVE-2020-29599 ImageMagick mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c. Vulnerable: <= 6.8.9.9-5+deb8u21 Fixed: 6.8.9.9-5+deb8u22 | 3.0.0-3.7.14 | |
| CM-33007 | The following vulnerability was announced in the apt packages: CVE-2020-27350: Missing input validation in the ar/tar implementations of APT, the high level package manager, could cause out-of-bounds reads or infinite loops, resulting in denial of service when processing malformed deb files. Vulnerable: <= 1.0.9.8.6 Fixed: 1.0.9.8.7 | 3.0.0-3.7.14 | |
| CM-32810 | The following vulnerability has been announced in the libflac8 package: CVE-2020-0499: In FLAC__bitreader_read_rice_signed_block of bitreader.c, there is a possible out-of-bounds read due to a heap buffer overflow. This could lead to remote information disclosure with no additional execution privileges needed. However, user interaction is needed for exploitation. Vulnerable: 1.3.0-3 Fixed: 1.3.0-3+deb8u1 | 3.0.0-3.7.14 | |
| CM-32797 | The following vulnerabilities have been announced in curl: CVE-2020-8284: Vulnerability to malicious FTP server with PASV response with different IP address.

| CM-32214 | CVE-2020-8037: The ppp de-capsulator in tcpdump 4.9.3 can be convinced to allocate a large amount of memory. The buffer should be big enough to hold the captured data, but it doesn’t need to be big enough to hold the entire on-the-network packet, if we haven’t captured all of it. Vulnerable: <= 4.9.3-1~deb8u1 Fixed: 4.9.3-1~deb8u2 | 3.0.0-3.7.13 | 3.7.14 |
| CM-32205 | CVE-2020-28196: There is a denial of service vulnerability in the MIT Kerberos network authentication system, krb5. The lack of a limit in the “ASN.1” decoder could lead to infinite recursion and allow an attacker to overrun the stack and cause the process to crash. Vulnerable: <= 1.12.1+dfsg-19+deb8u5 Fixed: 1.12.1+dfsg-19+deb8u6 | 3.0.0-3.7.13 | 3.7.14 |

| CM-31673 | CVE-2016-7949, CVE-2016-7950: The libxrender library has issues in the way various X client libraries handle the responses they receive from servers. Insufficient validation of data from the X server could cause out of boundary memory writes in the libXrender library potentially allowing the user to escalate their privileges. Vulnerable: 0.9.8-1 | 3.0.0-3.7.13 | 3.7.14 |
| CM-31631 | Several vulnerabilities were discovered in the Perl5 Database Interface (DBI). An attacker could trigger a denial-of-service (DoS), information disclosure and possibly execute arbitrary code. CVE-2013-7490: Using many arguments to methods for Callbacks may lead to memory corruption. CVE-2014-10401: DBD::File drivers can open files from folders other than those specifically passed via the f_dir attribute. CVE-2019-20919: The hv_fetch() documentation requires checking for NULL and the code does that. But, shortly thereafter, it calls SvOK(profile), causing a NULL pointer dereference. CVE-2020-14392: An untrusted pointer dereference flaw was found in Perl-DBI.

| CM-30863 | OpenSSH scp is vulnerable to CVE-2020-15778, where clients that have authorized access to the SSH server can execute commands on the server by copying maliciously named files. The two scenarios where an exploit may be useful to an attacker: -The user is authorized to scp but not ssh (based on the command option in the authorized_keys file), so this vulnerability can allow executing a remote command on the target computer when not authorized to do so.-An attacker plants a maliciously named file in a directory tree that someone later uses scp -r to copy over to the target computer.Be aware that restricting users to scp by using the command option in the authorized_keys file is not effective in preventing those users from executing arbitrary commands on the server.If you want to use scp -r to copy directory trees, avoid copying directory trees to which attackers may have added maliciously-named files. Archiving the directory tree with tar, zip, or a similar program, then copying the archive over to be extracted on the server avoids having to use scp -r altogether. In addition, OpenSSH provides sftp, which you can use instead of scp to copy files.To disable scp completely, use /bin/chmod 0 /usr/bin/scp . | 3.0.0-3.7.14 | |

| CM-27628 | The following security vulnerabilities have been announced in the nss/libnss3 library, which is not installed by default but is available in the repository: CVE-2019-11745: Out-of-bounds write when passing an output buffer smaller than the block size to NSC_EncryptUpdate CVE-2019-17007: nss: Handling of Netscape Certificate Sequences in CERT_DecodeCertPackage() may crash with a NULL deref leading to DoS See https://security-tracker.debian.org/tracker/source-package/nss for more information. Vulnerable: <= 3.26-1+debu8u7 Fixed: 3.26-1+debu8u9 | 3.0.0-3.7.10 | 3.7.11-3.7.14 |
| CM-27457 | If you delete, then re-add a PBR policy on an interface, the configured PBR policy is not programmed in the kernel or switchd. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-27456 | After making a series of PBR configuration changes using NCLU commands, the stale PBR entry is still present in the kernel. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-27351 | On rare occasions, after rebooting the MLAG secondary switch, one MLAG device might see the peer as down, which can cause traffic disruption to connected hosts. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-27299 | The protocol daemon bgpd crashes when a link/neighbor flaps if static routes pointing to Null0 are advertising through BGP.To work around this issue, reboot the switch, then remove the static routes or stop advertising these routes. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-27295 | IPv6 table rules might affect forwarding. For example, if you create the following rule in the /etc/cumulus/acl/policy.d/03-sshd.rules file, the rule counter increments but IPv4 SSH traffic might be dropped.[ip6tables] | 3.7.2-3.7.11 | 3.7.12-3.7.14 |
| CM-27279 | When ECMP routes have both VXLAN (symmetric routing) and non-VXLAN paths, the non-VXLAN path is incorrectly installed in the RIB and FIB to point across VXLAN. The non-VXLAN next-hop will be installed as an offload entry in the neighbor table (ip neigh show) with a mac address of 00:00:00:00:00:00. | 3.7.3-3.7.14 | |
| CM-27233 | If you change multiple BGP or BFD timers in the /etc/frr/frr.conf file and then reload FRR, a traceback is encountered and the change does not take effect. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-27174 | The ospfd daemon might crash with the following kernel trace:2019-11-06T23:00:08.261749+09:00 cumulus ospfd[5339]: Assertion ‘node’ failed in file ospfd/ospf_packet.c, line 671, function ospf_write | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-27120 | When an interface flap occurs, numbered IPv6 BGP sessions might fail to establish. To work around this issue, run the ip -6 route flush cache <IPv6-address> command to flush the IPv6 route cache. | 3.7.9-3.7.11 | 3.7.12-3.7.14 |
| CM-27096 | On the Edgecore AS6812 switch, you might see rare I2C errors. | 3.7.2-3.7.10 | 3.7.11-3.7.14 |
| CM-27094 | On the Delta AG9032v1 switch, smonctl and sensors report inaccurate PSU current and power. | 3.5.0-3.7.14 | |
| CM-27025 | On the Mellanox switch, ACL lookups are performed for VLAN matches when no rules with UNTAGGED match are present. | 3.7.2-3.7.10 | 3.7.11-3.7.14 |
| CM-26968 | When networking fails to start properly, an MLAG memory leak occurs, which might cause memory issues. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26954 | In the default VRF, VRRP might crash and stay in an initialize state. As a result, VRRP multicast traffic is not generated. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26921 | If you delete an undefined bond, then add a bond slave, the net commit command fails. | 3.7.9-3.7.14 | |
| CM-26913 | FRR configuration commands for an SVI interface might have the \n misplaced in the output. For example:sudo sh -c “printf ‘interface 50\nvrf TEST description L3 routing interface\n’ » /etc/frr/frr.conf" should be: sudo sh -c “printf ‘interface 50 vrf TEST\ndescription L3 routing interface\n’ » /etc/frr/frr.conf" To work around this issue, configure the interface manually in the /etc/frr/frr.conf file. | 3.7.9-3.7.14 | |
| CM-26894 | The neighmgrd service does not ignore neighbors on reserved devices (lo and management devices). This issue is not seen when management VRF is enabled. | 3.7.8-3.7.11 | 3.7.12-3.7.14 |
| CM-26875 | After you delete an IPv6 numbered BGP peer group neighbor, Cumulus Linux might continue to send route advertisements. To work around this issue, restart FRR after removing the IPv6 numbered configuration. | 3.7.9-3.7.14 | |
| CM-26838 | You might experience a bgpd memory usage increase and significant update exchanges due to host moves between VTEPs. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26829 | Frames received with a VLAN tag of 0 on an interface configured as a bridge port and forwarded to the CPU for processing might appear tagged with the native VLAN when viewed with tcpdump. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26769 | Setting ProtoDown on ports populated with SFP modules providing RJ-45 1000BASE-T interfaces does not cause the carrier to be dropped. The kernel shows carrier down; however, the remote device still shows a link. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26691 | BGP is configured with soft reconfiguration-in for its peers, which is not working correctly and causes routes to have an unexpected label. As a result, transit traffic is not forwarded by the switch. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26657 | When you install a large number of new rules with nonatomic mode enabled, there is a chance that you install more rules than the number of available slots in the slice, which results in the slice being completely wiped and reinstalled. This causes a large drop increase, including to cpu0, and might cause a major outage by dropping all BGP sessions. | 3.6.1-3.7.10 | 3.7.11-3.7.14 |
| CM-26655 | If you reconfigure an NTP server with NCLU using different trailing options after the IP address (such as iburst), an invalid configuration is added to the /etc/ntp.conf file. For example:net add time ntp server 1.2.3.4 iburst If you need to alter existing server configurations, first remove the server, commit, then re-add the server with any trailing options. | 3.7.9-3.7.14 | |
| CM-26599 | Auto-negotiation does not work with the QSFP28 cables and a remote system operating at 10G. Attempting to enable auto-negotiation with ethtool -s swp<#> autoneg on returns Operation not supported.To work around this issue, do not use auto-negotiation and set the local port speed to 10G. | 3.7.9-3.7.14 | |
| CM-26595 | The NCLU net show lldp command displays the speed of a ganged port group as the speed of one of the individual links, rather than the sum of their speeds. | 3.7.9-3.7.14 | |
| CM-26525 | When an MLAG peerlink frequently alternates states between learning and blocking, an excessive number of TCP sessions might be created, which results in the following error display:OSError: [Errno 24] Too many open files | 3.6.2-3.7.10 | 3.7.11-3.7.14 |
| CM-26523 | Package: hostapd CVE ID: CVE-2019-13377 CVE-2019-16275 Two vulnerabilities were found in the WPA protocol implementation found in wpa_supplication (station) and hostapd (access point). CVE-2019-13377 A timing-based side-channel attack against WPA3’s Dragonfly handshake when using Brainpool curves could be used by an attacker to retrieve the password. CVE-2019-16275 Insufficient source address validation for some received Management frames in hostapd could lead to a denial of service for stations associated to an access point. An attacker in radio range of the access point could inject a specially constructed unauthenticated IEEE 802.11 frame to the access point to cause associated stations to be disconnected and require a reconnection to the network. Fixed version: 1:2.8.0-cl4u3 | 3.7.0-3.7.10 | 3.7.11-3.7.14 |
| CM-26516 | Applying a policy-based routing (PBR) rule for all traffic from a host might disrupt ARP refresh for that connected host. | 3.7.5-3.7.14 | |
| CM-26450 | Cumulus Linux poed generates excessive debug log entries. These will be reduced in a future release. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-26448 | Traffic sent to the SVI IP address of a switch might be lost if all of the following conditions are met:
To workaround this issue, restart switchd. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26437 | NCLU crashes when you run the net add interface storage-optimized pfc command because non-ascii quotes exist in the datapath.conf file.To work around this issue, manually edit the /usr/lib/python2.7/dist-packages/cumulus/__chip_config/mlx/datapath.conf file and replace the non-ascii single quotes with ascii single quotes (standard single quote on the keyboard). | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26423 | NCLU requires you to specify an interface with multiple address-virtual statements in ascending MAC address order. | 3.7.5-3.7.14 | |
| CM-26412 | Mac learning is not disabled by default on a double tagged peer link interface resulting in the MAC address changing between the MLAG bond and the peer link. To work around this issue, disable MAC learning on QinQ VLANs by adding bridge-learning off to the VLAN stanza in the etc/network/interfaces file. | 3.7.9-3.7.14 | |
| CM-26383 | After upgrading to Cumulus Linux 3.7.9 on a Broadcom switch, CPU generated traffic (such as ICMP, OSPF, ARP, and so on) egresses access ports with a 802.1Q header or interfaces with a bridge-pvid, with a VLAN ID of 0. Equipment from other vendors might drop this traffic. | 3.7.9 | 3.7.10-3.7.14 |
| CM-26372 | FRR crashes when adding an IPv6 neighbor with extended-nexthop capability. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26351 | After you remove a subinterface, the BGP session stays in a Connect state. | 3.7.8-3.7.11 | 3.7.12-3.7.14 |
| CM-26308 | An interface alias configured outside FRR using iproute2 is imported into the FRR running configuration and overrides the internal description. After an FRR reload, this causes FRR to delete the interface alias in an inefficient way. Depending on how many interfaces with aliases you have configured, this can cause a FRR reload to time out.To work around this issue, remove the interface alias description from iproute2. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26288 | On the Mellanox switch, static VXLAN tunnels incorrectly allow traffic from any remote tunnel IP address. | 3.7.8-3.7.14 | |
| CM-26272 | On the Mellanox Spectrum switch, a route withdrawal might cause the associated next hop neighbor entry to be deleted in hardware but remain in the kernel. This can cause traffic going through the directly connected route to the removed neighbor entry to be forwarded to the CPU. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26256 | The net show evpn vni detail json command includes an extra empty dictionary at the end of the output. | 3.7.8-3.7.14 | |
| CM-26255 | On the Mellanox SN2700 switch, you cannot enable resilient hashing (RASH) and set the bucket size to 64 in the traffic.conf file. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26252 | The following CVEs were announced that affect the ghostscript package: CVE ID : CVE-2019-14811 CVE-2019-14812 CVE-2019-14813 CVE-2019-14817 It was discovered that various procedures in Ghostscript, the GPL PostScript/PDF interpreter, do not properly restrict privileged calls, which could result in bypass of file system restrictions of the dSAFER sandbox. We recommend that you upgrade your ghostscript packages. For the detailed security status of ghostscript, refer to its security tracker page at: https://security-tracker.debian.org/tracker/ghostscript | 3.7.0-3.7.10 | 3.7.11-3.7.14 |
| CM-26241 | On the Dell S5248F-ON switch, smond might generate syslog messages indicating that the fan input RPM is lower than the normal low speed of 2500 RPM. Speeds as low as 1700 RPM are acceptable in normal thermal environments; therefore, you can ignore these messages. | 3.7.6-3.7.11 | 3.7.12-3.7.14 |
| CM-26230 | When local-tunnelip is an SVI, the static VXLAN tunnel does not work; the next hop router receives the packet but drops it as it does not know where to forward the packet. The static VXLAN tunnel does works if local-tunnelip is a loopback or a physical layer 3 interface. | 3.7.8-3.7.14 | |
| CM-26225 | On the EdgeCore AS5712, AS6712, AS5812 and AS6812 switch, support for multiple PSU types results in log messages similar to the following:2019-09-05T05:15:17.246597+00:00 hp-6712-03 decode-syseeprom: Unable to find eeprom at /sys/bus/i2c/devices/11-0050/eeprom for psu2 | 3.7.9-3.7.12 | 3.7.13-3.7.14 |
| CM-26217 | NCLU does not allow you to configure OSPF NSSAs. For example:cumulus@switch:~$ net add ospf area 0.0.0.1 nssa To work around this issue, use FRR instead. For example: switch# configure terminal | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26181 | ACL rules, such as the following, fail to install if you use swp+ (interfaces mentioned as wildcards).-A FORWARD -i swp+ -j LOG You can now install such rules with swp+. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-26179 | If a hostname contains utf-8 characters, the NCLU net show lldp command outputs the following error:ERROR: ‘ascii’ codec can’t encode character u’\xe9’ in position 3: ordinal not in range(128) | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-26169 | Cumulus Linux does not map QinQ packets to VXLANs in a configuration with a VLAN-aware bridge and MLAG on the Trident3 platform. | 3.7.9-3.7.10 | 3.7.11-3.7.14 |
| CM-26158 | On the Mellanox switch, UFT profiles are unable to support the documented capacity for routes to addresses that are more than 64 bits in length. The listed capacities assume 64-bit destination IP addresses. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26147 | On the EdgeCore AS4610 switch, the ping command fails unless you run the command with sudo.To work around this issue, run the following commands: cumulus@switch:~$ sudo setcap cap_net_raw+ep /usr/share/mgmt-vrf/bin/ping Run the following command to verify the workaround:
You should see the following output:
| 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-26146 | clagd memory consumption increases under certain unknown conditions. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-26138 | You cannot specify a source and destination MAC address in an ERSPAN ebtables rule. For example, the following rule does not work:-A FORWARD -i swp5 -s 00:25:90:b2:bd:9d -d 50:6b:4b:96:c4:04 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-26137 | ERSPAN in ebtables does not work for VNIs. For example, the following rule does not work:-A FORWARD -i vni10 -j erspan –src-ip 100.1.1.2 –dst-ip 100.1.1.1 –ttl 64 | 3.7.6-3.7.14 | |
| CM-26136 | In an ebtables rule, ERSPAN (upper case) does not work. You need to specify erspan (lower case). | 3.7.6-3.7.14 | |
| CM-26126 | Tomahawk 40G DACs cannot disable auto-negotiation. | 3.7.7-3.7.14 | |
| CM-26024 | On switches with the Spectrum ASIC, the underlay hashes VXLAN packets for a given overlay flow randomly. To work around this issue, configure the ECMP hash seed to the same value on the EVPN egress leaf switches. | 3.7.7-3.7.12 | 3.7.13-3.7.14 |
| CM-25973 | After a remote VTEP peer link goes down, the tunnel destination IP address might be incorrect in hardware, which might cause loss of overlay communication between VTEPs. | 3.7.8-3.7.10 | 3.7.11-3.7.14 |
| CM-25955 | Lenovo switches do not send or receive LLDP on eth0 interfaces. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-25923 | The default route injected through OSPF when you configure default-information originate always is unreliable and might age out unexpectedly.To work around this issue, rely on a different source of default route other than injection with default-information originate. | 3.7.8-3.7.14 | |
| CM-25890 | In some cases, the switchd service might warn of excessive MAC moves from one switch port to itself (for example, from swp18 to swp18). | 3.7.0-3.7.14 | |
| CM-25859 | The MTU of an SVI cannot be higher than the MTU on the bridge. Changing the MTU on the SVI with NCLU does not update the bridge MTU. The net commit command succeeds even though the MTU is not changed as expected.To work around this issue, change the MTU on all SVIs and the bridge manually in the /etc/network/interfaces file, then apply the change with the ifreload -a command. | 3.7.7-3.7.14 | |
| CM-25824 | NCLU restarts FRR when attempting to remove a BGP VRF stanza. This happens regardless of whether the VRF is valid/configured elsewhere on the switch or the removal is successful. To work around this issue, remove the stanza using vtysh. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-25815 | When an SVI with a virtual MAC is configured with a layer 2 VNI in an EVPN environment, if you replace the /etc/network/interfaces file with a different file that does not have the SVI and layer 2 VNI configuration, the original virtual MAC is not populated through the EVPN route until FRR is restarted. | 3.7.6-3.7.14 | |
| CM-25796 | Received EVPN type-5 and type-2 MACIP routes are not installed in the kernel (and hardware) routing tables for the associated VRF, which causes traffic to be blackholed. The failure to install the default route causes complete reachability failure for the particular tenant on the affected racks. The routes that are not installed are seen as “inactive” in the routing subsystem (FRR) VRF routing table. This problem is rare and can occur only in EVPN configurations that have user-configured route targets (RTs) for tenant VRFs, and only following a restart of FRR. To work around this issue, either restart the FRR service on the affected switch with the sudo systemctl restart frr.service command or bounce the layer 3 SVI for the affected VRF; for example:ifdown vlan123 ; sleep 2 ; ifup vlan123 You can run the net show vrf vni command to print a mapping of VRF : L3-VNI : L3-SVI. | 3.7.5-3.7.14 | |
| CM-25794 | Under certain conditions, EVPN next hops might not be removed when the contributing peer goes down or might not be populated when the BGP session to the contributing peer comes up. You can prevent EVPN next hops from not being removed when the contributing peer goes down by specifying static MAC addresses on all layer 3 VNIs. There is no workaround for preventing EVPN next hops from not being populated when the BGP session to the contributing peer comes up. | 3.7.2-3.7.14 | |
| CM-25766 | On the Dell-N3048EP-ON switch, when you run the sudo -E apt upgrade command, the upgrade does not work. | 3.7.7-3.7.14 | |
| CM-25747 | When transitioning from a down state to an up state due to peerlink failure and recovery, MLAG does not start the initDelay timer before trying to bring everything back up. | 3.7.7-3.7.10 | 3.7.11-3.7.14 |
| CM-25740 | On the Broadcom Maverick switch with a QinQ configuration, the packets coming into the CPU might be tagged incorrectly; for example, 802.1ad + 802.1q tags are expected in the packets but the packets have 802.1q + 802.1q tags. To work around this issue, configure the bridge with bridge-vlan-protocol 802.1ad:cumulus@switch:~$ net add bridge mybridge vlan-protocol 802.1ad | 3.7.6-3.7.14 | |
| CM-25718 | IF-MIB::ifHCInOctets reports significantly lower values than reported by interface counters seen elsewhere. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25694 | If a packet is policed by ebtables, it does not increment an ACL drop on the ingress interface. Instead, it increments the TDBGC3/6 drop counter to the CPU. | 3.7.6-3.7.14 | |
| CM-25693 | After you issue the NCLU net del bgp vrf <vrf> autonomous-system <AS> command and commit the change, Cumulus Linux does not remove the configuration from the /etc/frr/frr.conf file or the net show config commands. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-25672 | snmpd fails because NCLU does not remove agentaddress @vrf lines when running the net add snmp-server listening-address all command. | 3.7.4-3.7.10 | 3.7.11-3.7.14 |
| CM-25665 | On the Broadcom Trident 3 switch, VXLAN encapsulated packets are dropped on the ingress port (tagged layer 2 port) during transit forwarding (the local switch does not terminate the VXLAN tunnel). An example of where this two-layer VXLAN inside VXLAN encapsulation might occur:
| 3.7.5-3.7.11 | 3.7.12-3.7.14 |
| CM-25641 | If the BMC operating system fails to respond to IPMI, you see a traceback in bmcd and all the sensors might report ABSENT devices in smonctl.To work around this issue, power cycle the switch. | 3.7.6-3.7.12 | 3.7.13-3.7.14 |
| CM-25640 | When you configure the switch to send an EAP request with the net add dot1x send-eap-request-id command, the switch ignores re-authentication attempts and does not send back an EAPol. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25505 | In EVPN symmetric or centralized configurations with BGP peering over a peer link, VXLAN routed packets transiting an MLAG peer are dropped until the clagd init-delay timer expires during the bring-up sequence following a reboot.The problem is caused by a race condition when programming the anycast IP address (used to terminate VXLAN tunnels), where the hardware is programmed before the software by clagd.To work around this issue, configure the BGP path across the peer link to be less preferred. The example below uses AS path prepending and the MLAG switches are iBGP neighbors. However, other BGP configurations achieve the same result. In the /etc/frr/frr.conf file, make a new AS path access list and route map to apply BGP pre-pending of the local ASN one or more times. For example:
| 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25447 | When you define a trap destination using @mgmt, snmpd indicates that the network is unreachable even though the IP address is reachable in the management VRF.To work around this issue, remove @mgmt vrf references in the /etc/snmp/snmpd.conf file, stop snmpd, then start snmpd manually in the management VRF with the systemctl start snmpd@mgmt command. | 3.7.6-3.7.10 | 3.7.11-3.7.14 |
| CM-25404 | hsflow disregards the setting for agent.cidr in the /etc/hsflowd.conf file and selects an IPv6 agent address. The source IP address of the hsflowd packet is IPv4, but the agent address in the hsflow payload shows IPv6. | 3.7.6-3.7.14 | |
| CM-25400 | If an SVI exists in the configuration before you assign it an IP address, when you do assign the IP address with the NCLU command, the vlan-id and the raw-device bridge stanzas are not added automatically. | 3.7.6-3.7.14 | |

| CM-25298 | The following CVEs were announced in a Debian Security Advisory that affects vim modelines. Package: vim and neovim CVE ID: CVE-2019-12735 Debian Bugs: 930020, 930024 getchar.c in Vim before 8.1.1365 and Neovim before 0.3.6 allows remote attackers to execute arbitrary OS commands via the :source! command in a modeline, as demonstrated by execute in Vim, and assert_fails or nvim_input in Neovim. For the detailed security status, refer to the security tracker page at: https://security-tracker.debian.org/tracker/CVE-2019-12735 https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-12735.html https://github.com/numirias/security/blob/master/doc/2019-06-04_ace-vim-neovim.md Cumulus Networks recommends that you disable modelines in the the vimrc file (set nomodeline) to use the securemodelines plugin or to disable modelineexpr (since patch 8.1.1366, Vim-only) to disallow expressions in modelines.To check if you have modelines enabled, open vim and enter: :set modeline? If vim returns nomodeline, you are not vulnerable. If you are vulnerable or you want to ensure your security with this issue, add these lines to your vimrc file:set modelines=0 set nomodeline modeline is enabled by default. Verify that you do not have any existing lines in .vimrc that set modelines or modeline. | 3.0.0-3.7.10 | 3.7.11-3.7.14 |
| CM-25001 | The following CVEs were announced in Debian Security Advisory DSA-444-1, DSA-4447-1 and affect the linux kernel and microcode. Package: linux CVE ID: CVE-2018-12126 CVE-2018-12127 CVE-2018-12130 CVE-2019-11091 Multiple researchers have discovered vulnerabilities in the way the Intel processor designs have implemented speculative forwarding of data filled into temporary microarchitectural structures (buffers). This flaw could allow an attacker controlling an unprivileged process to read sensitive information, including from the kernel and all other processes running on the system or cross guest/host boundaries to read host memory. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/mds.html for more details. To fully resolve these vulnerabilities it is also necessary to install updated CPU microcode. Contact your hardware ndor for microcode uppdates. In addition, this update includes a fix for a regression causing deadlocks inside the loopback driver. Fixed in version 4.19.76-1+cl4u1 | 3.0.0-3.7.14 | |
| CM-24894 | The maximum-prefix configuration under the IPv4 address family has an optional restart value, which you can configure. This configuration is ignored and, instead of restarting the sessions every x minutes, the peer constantly changes between established and idle due to the prefix count being exceeded. | 3.7.5-3.7.14 | |
| CM-24799 | On switches with the Trident2 ASIC, 802.1Q-encapsulated control plane traffic received on an interface with 802.1AD configured subinterfaces might be dropped. This issue only affects QinQ configurations. | 3.7.5-3.7.14 | |
| CM-24751 | On the QuantaMesh T4048-IX8 or EdgeCore AS7326-56X switch, when using a 1000BASE-T SFP module, the module LEDs do not light to reflect link status. | 3.7.3-3.7.14 | |
| CM-24703 | The Dell N3048EP-ON switch does not support 1G Base-T modules in the SFP ports. | 3.7.7-3.7.14 | |
| CM-24686 | On the EdgeCore AS5812-54X switch, the PSU2 Fan1 fluctuates between OK and LOW. When the fan speed is reported as LOW, the RPM is shown as a negative number. | 3.7.3-3.7.14 | |
| CM-24652 | In an EVPN environment, the centralized MAC address is not installed on the MLAG pair because Cumulus Linux does not perform an SVI MAC check per VLAN. This issue does not affect a pure distributed routing (symmetric or asymmetric) environment or a pure centralized routing environment. | 3.7.0-3.7.14 | |
| CM-24618 | If the interface alias contains a single or double quotation mark, or an apostrophe, the net show configuration commands fail with the following error:ERROR: No closing quotation See /var/log/netd.log for more details. | 3.6.1-3.7.14 | |
| CM-24473 | SNMP incorrectly requires engine ID specification. | 3.7.4-3.7.14 | |
| CM-24435 | When you use NCLU to configure a route map, the parser allows for glob matching of interfaces for a match interface condition when there can only be a single interface matched. The proper syntax is to use multiple route map clauses, each matching a single interface, instead of a single clause matching multiple interfaces. For example, this command is incorrect: net add routing route-map Proxy-ARP permit 25 match interface swp9-10 These commands are correct: net add routing route-map Proxy-ARP permit 25 match interface swp9 net add routing route-map Proxy-ARP permit 30 match interface swp10 | 3.7.2-3.7.14 | |
| CM-24426 | NCLU allows for the configuration of addresses on VRF interfaces, but tab completion for the net add vrf <name> command just displays
Tab completion for the net add vrf <name> ip address <address> command works correctly. | 3.7.4-3.7.14 | |
| CM-24379 | On the Maverick switch, CPU forwarded packets might be dropped when there is no route to a leaked host route. | 3.7.5-3.7.14 | |
| CM-24343 | The net del bridge bridge mcsnoop yes command does not return the value to the default of disabled.To work around this issue, use the net add bridge bridge mcsnoop no command to delete the mcsnoop attribute and return to the default value. | 3.7.4-3.7.14 | |
| CM-24332 | On the Broadcom switch, when moving configuration from bridged to routed (or toggling from routed to bridged to routed), some traffic is not seen by the kernel. This can cause BGP to not establish on a transit node. | 3.7.3-3.7.14 | |
| CM-24272 | When you try to configure the VRRP priority and advertisement-interval with NCLU on a traditional mode bridge, the net commit command fails.To work around this issue, use the vtysh command (inside FRR) to change the VRRP priority or advertisement-interval on traditional bridges. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface br0.100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# vrrp 1 advertisement-interval switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24271 | On SVIs in a VLAN-aware bridge, you cannot change the VRRP priority with NCLU. To work around this issue, run the vtysh command inside FRR to change the default priority. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface vlan100 switch(config-if)# vrrp 1 priority 110 switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24270 | Cumulus Linux uses VRRPv3 as the default version, and enables both preempt and accept mode by default. You cannot change these default values with NCLU. To work around this issue, run the vtysh commands (inside FRR) to change the default values. For example: cumulus@switch:~$ sudo vtysh switch# configure terminal switch(config)# interface swp4 switch(config-if)# vrrp 1 version 2 switch(config-if)# no vrrp 1 preempt switch(config-if)# end switch# write memory switch# exit cumulus@switch:~ | 3.7.4-3.7.14 | |
| CM-24262 | NCLU does not honor auto all in the /etc/network/interfaces file and removes the existing configuration if no individual auto <iface> lines exist. | 3.7.3-3.7.14 | |
| CM-24241 | When you try to remove a BGP peer group configuration with NCLU, the command fails but no warning message is shown. For example:cumulus@switch:~$ net del bgp neighbor fabric peer-group ‘router bgp 65001’ configuration does not have ‘neighbor fabric peer-group’ | 3.7.2-3.7.14 | |
| CM-24222 | When an LDAP user that does not have NCLU privileges (either in the netshow or netedit group, or in the /etc/netd.conf file) runs an NCLU command, a traceback occurs instead of a permissions error. | 3.7.0-3.7.14 | |
| CM-24035 | On the Edgecore 4610-54P switch, automatic medium-dependent interface crossover (auto-MDIX) stops working on a 100M full duplex interface and does not detect the required cable connection type. | 3.7.2-3.7.14 | |
| CM-23825 | The net add interface <interface> ptm-enable command adds no ptm-enable for that interface in the frr.conf file.Running the net add or the net del command does not remove no ptm-enable from the frr.conf file. You have to remove it manually using vtysh. | 3.7.2-3.7.14 | |
| CM-23792 | When you delete post-up and pre-down IP peer entries from the etc/network/interfaces file, then run the ifreload command, the IP addresses are not removed and the route remains in the route table.To work around this issue, either delete the IP addresses without the /32 mask component or flush the IP addresses for the interface with the ip addr flush dev <interface> command. | 3.7.0-3.7.14 | |
| CM-23696 | IPv6 multicast traffic destined to an unregistered multicast group is flooded to all ports in a bridge despite the bridge.optimized_mcast_flood = TRUE setting in the /etc/cumulus/swichd.conf file. | 3.7.2-3.7.14 | |
| CM-23665 | NCLU automatically adds the VLAN ID (for the layer 3 VNI/SVI) to the bridge when you run net add vxlan <layer3-vni> bridge access <vlan>. This configuration breaks network connectivity in an EVPN symmetric routing configuration using MLAG.To restore connectivity, remove the VLAN ID from the bridge. | 3.7.2-3.7.14 | |
| CM-23661 | On the Mellanox switch, when you configure a GRE tunnel, the traffic behind the local tunnel endpoint destined through the GRE tunnel is software-forwarded. | 3.7.2-3.7.14 | |
| CM-23651 | In an EVPN symmetric routing configuration, when an IP address is frozen, kernel neighbor table information and kernel VRF routing table information about the frozen IP address might be out-of-sync. | 3.7.3-3.7.14 | |
| CM-23584 | When you configure a control plane ACL to define permit and deny rules destined to the local switch, NCLU programs the control plane ACL rules into the FORWARD chain. | 3.7.2-3.7.14 | |
| CM-23570 | On an RMP/1G-T switch, when you remove link-speed 100 with the NCLU command or by editing the etc/network/interfaces file to revert the 100M interface to the default (1G auto), the interface fails to recover and does not come back up.After you remove the link-speed, ethtool shows the advertised link modes as not reported and Speed/Duplex as unknown.To work around this issue and bring the interface back up, either restart switchd or use ethtool to configure the speed, advertised, duplex or MDI-X settings.Note: The advertised link mode gets set incorrectly if you include 1000baseT/Half. The port will come up successfully at 1G. | 3.7.2-3.7.14 | |
| CM-23422 | portwd allows an error to change the module type based on the error. For example, a bad write to a module might cause the module type to flap, which causes the link itself to flap. | 3.7.0-3.7.14 | |
| CM-23418 | For QSFP modules, the sudo ifdown command does not disable the Tx laser. | 3.7.2-3.7.14 | |
| CM-23417 | If you use NCLU to create an iBGP peering across the peer link, running the net add bgp l2vpn evpn neighbor peerlink.4094 activate command creates a new eBGP neighborship when one has already been configured for iBGP. This is unexpected; the existing iBGP configuration is valid. | 3.7.0-3.7.14 | |
| CM-23397 | On the Broadcom switch, when a link-local multicast frame is received on an access port with a VNI in the bridge, two copies of the packet are sent across the VNI to remote VTEPs and the receiving hosts observe duplicate packets. | 3.6.2-3.7.14 | |
| CM-23125 | The OpenSSL package on Cumulus Linux 3.x has a vulnerability similar to CVE-2018-0734. (The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key). According to Debian upstream, this version “is not vulnerable [to CVE-2018-0734 exactly]. Nevertheless, there is a bug fix that futher reduces the amount of leaked timing information. It got no CVE on its own and introduced this vulnerability.“ Vulnerable on CL3: 1.0.1t-1+deb8u12 | 3.0.0-3.7.14 | |
| CM-23123 | When you enable FEC (RS or BaseR) on an interface, removing the configuration from that interface does not revert the FEC status to off/none. | 3.7.2-3.7.14 | |
| CM-23075 | There is a limitation on the number of SVI interfaces you can specify as DHCP relay interfaces in the /etc/default/isc-dhcp-relay file. For example, 1500 SVI interfaces causes the dhcrelay service to exit without a core file and logs similar to the following are generated for the interfaces:2018-11-10T23:35:30.992370-08:00 Dev dhcrelay: Listening on LPF/vlan.101/a0:00:00:00:00:51 2018-11-10T23:35:30.993472-08:00 Dev dhcrelay: Sending on LPF/vlan.101/a0:00:00:00:00:51 Eventually the dhcrelay service stops. | 3.7.1-3.7.14 | |
| CM-23021 | When you run the mstpctl command, you might see the bridge-port state as blocking when it is actually disabled. You might see the same incorrect bridge-port state when other programs or tools use the output of mstpctl; for example, SNMP output from the BRIDGE-MIB. | 3.7.1-3.7.14 | |
| CM-23016 | When FRR restarts, snmp<span class="error">[err]</span> dev/kmem: Permission denied error messages are recorded in the log file and SNMPd might crash periodically. | 3.7.5-3.7.10 | 3.7.11-3.7.14 |
| CM-23004 | The local fallback account authenticates using the local password when the RADIUS or TACACS service is up. The expected behavior is for this to fail and only succeed when the RADIUS OR TACACS server fails to respond. | 3.7.1-3.7.14 | |
| CM-22937 | NCLU SNMPv3 user configuration (add, delete, modify) does not complete. Changes are made to the /etc/snmp/snmpd.conf file but the SNMPv3 user cache file /var/lib/snmp/snmpd.conf fails to update correctly and the configuration does not reflect in operation.To work around this issue, stop snmpd, remove the cache file, then restart snmpd. | 3.6.0-3.7.14 | |
| CM-22849 | When an event in the network, such as a switchd or networking service restart, leads to an OVSDB server high availability transition, an ovs-vtepd core might occur.This core generation has no effect on the functionality of high availability when the active OVSDB server is back in the network. | 3.7.2-3.7.14 | |
| CM-22808 | When you try to stop hsflowd on the Trident II+ switch with the systemctl stop hsflowd command, the process hangs until you stop it with SIGKILL. | 3.5.2-3.7.14 | |
| CM-22794 | The Dell S5048F-ON switch (with reverse airflow, rear to front), shows the Temp-3 sensor as absent. | 3.6.2-3.7.14 | |
| CM-22605 | On a Dell S4048 switch, when you set the eth0 speed to 100, either with NCLU or by editing the /etc/network/interfaces file, the igb driver crashes, which brings down eth0.To work around this issue:
| 3.5.3-3.7.10 | 3.7.11-3.7.14 |
| CM-22591 | CVE-2018-5391 (FragmentSmack) is a network vulnerability where an attacker can trigger time and calculation expensive fragment reassembly with specially crafted packets, leading to a denial of service. On a Cumulus Linux switch, the impact is limited to control plane and management plane traffic. Any control plane traffic coming in the front panel ports will be limited by existing policer ACLs. To work around this issue, create a file called /etc/sysctl.d/ip.conf and add these settings:net.ipv4.ipfrag_low_thresh = 196608 | 3.7.0-3.7.11 | 3.7.12-3.7.14 |
| CM-22583 | Single tagged ARP requests received on a QinQ-over-VXLAN access port are dropped if ARP suppression is enabled on an unrelated VNI. | 3.6.0-3.7.14 | |
| CM-22554 | If you try to bring down several members of a bond remotely at the same time, the link state of one of the interfaces might not transition correctly to the down state; however, all links show down in hardware. | 3.6.2-3.7.14 | |
| CM-22538 | When deleting an interface using NCLU, if the /etc/network/interfaces alias is different than the /etc/frr/frr.conf description, the net commit command returns the following error:/etc/frr/daemons was modified by another user. Despite this error, the change is made and the description is removed from the frr.conf file. | 3.6.2-3.7.10 | 3.7.11-3.7.14 |
| CM-22386 | The BFD packet redirection logic used by OVSDB server high availability mode redirects BUM packets across the peer link. The iptables rule for redirection does differentiate between BFD and non-BFD VXLAN inner packets because the service node sends all frames with its own IP address as the tunnel source IP address. The VXLAN encapsulated BUM packets do not get forwarded to the CPU and do not go through the iptable redirection rule; only VXLAN encapsulated BFD packets get forwarded to the CPU due to the inner MAC DA lookup in hardware. | 3.7.0-3.7.14 | |
| CM-22301 | For an unresolved address, the IPROUTER default policer rule has been modified to not match on packets exiting a TUNNEL and headed to the CPU to resolve the address via ARP. As a result, the following default rule no longer matches TUNNEL ingress packets.A $INGRESS_CHAIN –in-interface $INGRESS_INTF -m addrtype –dst-type IPROUTER -j POLICE –set-mode pkt –set-rate 400 –set-burst 100 These packets are now policed by catch all rules. To work around this issue, the VPORT value on a TRIDENT switch must be changed from binary 011 to 100. | 3.6.1-3.7.14 | |
| CM-22287 | On the EdgeCore AS7712 (Tomahawk) switch running in atomic mode, when a layer 3 ECMP path is brought down, traffic traversing the path stops working for about four seconds. When the switch is changed to non-atomic mode, the delay is less than one second. This issue is seen across OSPF and static ECMP routes. | 3.6.2-3.7.14 | |
| CM-22277 | On the Broadcom switch with the Trident3 ASIC, the ECN-CE bit is set by default on transit traffic. This might result in hosts adjusting traffic behavior if they are configured for the ECN feature. In Cumulus Linux 3.7.11, the default behavior changed; the ECN-CE bit is no longer set by default on transit traffic. | 3.7.3-3.7.10 | 3.7.11-3.7.14 |
| CM-22274 | To ease interoperation with non-Cumulus devices, it is possible to configure the route-target import and export values under the layer 2 VNI EVPN configuration. The same configuration does not work for both layer 2 VNI and layer 3 VNIs. Set the EVPN address-family within the VNI context when configuring the route-target in the layer 2 VNI. Set the EVPN address-family without the VNI context when configuring the route-target in the layer 3 VNI. | 3.6.0-3.7.14 | |
| CM-22252 | On the Edgecore OMP-800, there is no Power Supply information from the sensor or from smonctl. The platform driver has support for the PSUs but this was not added to the sensors infrastructure.This is a known limitation on the OMP-800 platform. | 3.6.2-3.7.14 | |
| CM-22228 | On switches with the Trident 2+ ASIC, counters associated with VLANs and VRFs are not working. | 3.7.0-3.7.14 | |
| CM-22205 | If a user is in vtysh when FRR is restarted, the running configuration in that vtysh session shows empty. | 3.6.2-3.7.14 | |
| CM-22138 | When you run the NCLU net show system command or the NetQ netq inventory command on the Edgecore OMP-800 switch, the output does not show any port or chip information. | 3.6.2-3.7.14 | |
| CM-22041 | At a high CPU transmit traffic rate (for example, if there is unexpected CPU generated flooding or replication in software), when the ASIC packet driver cannot keep up with the transmit rate because there are no free DMA buffers, it can back pressure by suspending the switch port transmit queues. This can fill up the application socket buffers resulting in No buffer space available error messages on protocol sockets.When the driver recovers, it automatically resumes the transmit queues. In most cases these error messages are transient. In rare cases, the hardware queues might get stuck, which you can recover with a switchd restart. | 3.4.3-3.7.14 | |
| CM-22020 | On the Trident3 switch, static PIM with IIF based on a layer 2 bridge does not work reliably. PIM Join via signaling is required for IPMC to work properly. To work around this issue, use dynamic signaling (joins) to manage IP multicast traffic. | 3.7.0-3.7.14 | |
| CM-21898 | On a Trident3 switch, IGMP packets are not policed by the police rule in the 00control ACL file. The packets are policed by the catchall policer in the 99control ACL file instead.-A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100To work around this issue, let the CPU bound IGMP packet hit the following rule and change the policer rate to a desired value for IGMP packets: -A $INGRESS_CHAIN -p ipv4 -d 01:00:5e:00:00:00/ff:ff:ff:80:00:00 -j police --set-mode pkt --set-rate 100 --set-burst 100Typically, the destination MAC address 01:00:5e:xx:xx:xx is used only for PIM/IGMP control and data stream packets. However, this workaround cannot handle data stream multicast packets that are not TCP/UDP; this is not typically done. | 3.6.2-3.7.12 | 3.7.13-3.7.14 |
| CM-21785 | The source address of the ICMPv6 time exceeded message (traceroute hop) is sourced from the wrong VRF when the traceroute target resides on the same switch but in a different VRF. | 3.6.2-3.7.14 | |
| CM-21769 | On the Mellanox switch, GRE tunneling does not work if the tunnel source is configured on an SVI interface. If the tunnel source is configured on a physical switch port, then tunneling works as expected. | 3.6.1-3.7.13 | 3.7.14 |
| CM-21678 | On a Dell switch with a Maverick ASIC, NetQ might receive false alerts like the following via PagerDuty: cumulus@switch:~$ netq show sensors temp changes | grep absent | grep -v psu P2Leaf01 temp9 networking asic die temp sensor absent 43 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to find driver path: /cumulu Add 7d:22h:1m:41s P2Leaf01 temp6 networking asic die temp sensor absent 47 105 100 5 Unable to read temp4_highest Add 9d:23h:26m:6s P2Leaf01 temp6 networking asic die temp sensor absent 45 105 100 5 Unable to read temp4_highest Add 14d:22h:46m:45s This message might occur as a result of a timeout at the hardware level, or the switch might be reporting a failure to get a response. | 3.5.3-3.7.14 | |
| CM-21667 | FRR does not add BGP ttl-security to either the running configuration or to the /etc/frr/frr.conf file when configured on a peer group instead of a specific neighbor.To work around this issue, add ttl-security to individual neighbors instead of the peer group. | 3.6.1-3.7.14 | |
| CM-21379 | If a primary route becomes unavailable (for example, you run ifdown on the switch port), the backup route remains inactive and is not installed into FIB.To work around this issue, configure routes as ECMP: cumulus@switch:~$ net del routing route 4.1.1.0/24 1.1.1.1 10 cumulus@switch:~$ net add routing route 4.1.1.0/24 1.1.1.1 cumulus@switch:~$ net commit | 3.5.3-3.7.14 | |
| CM-21373 | Debian issued the following security advisory, DSA-4231-1, which affects the libgcrypt20 package. This advisory applies only to the the Debian Stretch release. Debian Jessie, upon which Cumulus Linux 3.0 - 3.6.2 is based, is vulnerable. CVE-2018-0495 It was discovered that Libgcrypt is prone to a local side-channel attack allowing recovery of ECDSA private keys. For the stable distribution (stretch), this problem has been fixed in version 1.7.6-2+deb9u3. We recommend that you upgrade your libgcrypt20 packages. For the detailed security status of libgcrypt20, refer to its security tracker page at: https://security-tracker.debian.org/tracker/libgcrypt20 | 3.6.2-3.7.10 | 3.7.11-3.7.14 |
| CM-21332 | When two VLAN subinterfaces are bridged to each other in a traditional mode bridge, switchd doesn’t assign a gport to the subinterface, even though a gport is expected for each VLAN subinterface.To work around this issue, you can do one of two things:
| 3.5.3-3.7.14 | |
| CM-21278 | The net show lldp command sometimes shows the port description in the Remote Port field. The net show interface command shows the correct value in the Remote Host field.To work around this issue, use net show interface command for LLDP output when connected to Cisco equipment. | 3.5.3-3.7.10 | 3.7.11-3.7.14 |
| CM-21058 | The advertised routes list may be empty for an EVPN peering even though the remote switch reports received routes. | 3.6.0-3.7.14 | |
| CM-21055 | On the Mellanox switch, the destination MAC address of ERSPAN GRE packets is set to all zeros; therefore, the first transit switch might drop packets. | 3.6.0-3.7.13 | 3.7.14 |
| CM-20813 | Span rules matching the out-interface as a bond do not mirror packets. | 3.6.0-3.7.14 | |
| CM-20693 | In NCLU, you can only set the community number in a route map. You cannot set other community options such as no-export, no-advertise, or additive.This is a known limitation in network-docopt and is documented in the Cumulus Linux user guide. | 3.5.1-3.7.14 | |
| CM-20534 | The default BGP instance must be provisioned and always exist for proper operation of dynamic leaking of routes between VRFs. | 3.7.0-3.7.10 | 3.7.11-3.7.14 |
| CM-20508 | The Cumulus-Resource-Query-MIB defines the ability to gather buffer utilization status but when these objects are polled, they return nothing. | 3.5.3-3.7.14 | |
| CM-20480 | The python-crypto package, which is not installed by default on Cumulus Linux, but is present in the repository to be installed, has the following security vulnerability in the version available for Cumulus Linux 3.x: CVE-2018-6594: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto’s ElGamal implementation. More information at https://security-tracker.debian.org/tracker/CVE-2018-6594 . | 3.0.0-3.7.14 | |
| CM-20132 | On Trident2 switches running 802.3x regular link pause, pause frames are accounted in HwIfInDiscards counters and are dropped instead of processed. | 3.5.2-3. |
