995633 : CVE-2019-10160: Python vulnerability

Component: F5OS-C

Symptoms:
A security regression of CVE-2019-9636 was discovered in python, since commit d537ab0ff9767ef024f26246899728f0116b1ec3, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application.

1045177 : Stale interfaces left behind upon portgroup mode change from 100GB to 40GB

Component: F5OS-C

Symptoms:
There are situations when stale interfaces are left behind in the config cdb, when the portgroup mode changes from 100GB to 40GB. This causes l2-agent on the blade to exit.

Conditions:
-- reset-to-defaults/backup/restore
OR
-- live install

-- change the portgroup mode from 100GB to 40GB
-- commit

Impact:
The interfaces corresponding to portgroups are not present and stale interfaces are left behind.

Workaround:
Steps for mitigation:
1) verify the issue is caused by the lack of pgindex in cdb:

a) from config mode in partition, create a backup file
(config)# system database config-backup name test
b) look for pgindex in the /var/F5/partition{id}/configs/test
c) if no entries are found, this is the issue

2) remove the slots corresponding to the impacted partition from the system controller configuration and commit

3) re-add the slots corresponding to the impacted partition from the system controller configuration and commit

4) from the partition cli, ensure the system redundancy shows the blade is present and operational

5) from the partition cli, change the portgroup mode from 100GB to 40GB and commit (example below)
(config)# portgroups portgroup 1/1 config mode MODE_40GB; top
(config)# portgroups portgroup 1/2 config mode MODE_40GB; top
(config)# commit


6) wait for the blades to resync by monitoring 'show system redundancy'

At this point the interfaces should be republished matching the new 40GB mode.

Fix:
Proper interfaces will be published to match the portgroup modes that were changed.

1044257 : Removal of old chassis partition images might cause tenant issues after blade reboot★

Links to More Info: BT1044257

Component: F5OS-C

Symptoms:
After upgrading the system to version 1.1.4 and old chassis partition images are removed from the system, tenants might not start up correctly after a reboot of the blade hosting the chassis partition.

Conditions:
This might occur if the tenant was started after the system was upgraded to an interim release (such as 1.1.1, 1.1.2, 1.1.3), after originally running version 1.1.0.

Impact:
Tenants will not start correctly, will not pass traffic, or be accessible on their management interfaces.

Under certain circumstances, a version of controller or partition services may appear "not in use" in ConfD/GUI tables, but removal of that version is still blocked because other parts of the service package are still in use by other system components.

Conditions:
1. Attempt to remove an (apparently inactive) version of controller or partition services via ConfD or GUI.
2. Other components on the system still silently depend on that version of services, even though ConfD/GUI output does not reflect this.

Impact:
Unable to remove versions of software that appear unused, and the cause is unclear.

Workaround:
N/A

Fix:
Removal of platform services that appear "unused" is no longer blocked by hidden higher-level component dependencies

1042785-1 : Configuring spanning tree (stp) while disabled may display incorrect state

Links to More Info: BT1042785

Component: F5OS-C

Symptoms:
While stp is disabled, configuring a field such as MSTP max-hop causes the the enabled-protocol to display an incorrect value.

Conditions:
Delete enabled-protocol configuration field.
Delete another stp configuration field such as MSTP max-hop

Impact:
The stp enabled-protocol display is incorrect.

Workaround:
To mitigate, do not configure stp while not enabled.

Fix:
Configuring stp while disabled will not lead to incorrect display.

1042273 : ETCD-HA Instance may not initialize correctly after PXE-booting the system controller.

Links to More Info: BT1042273

Component: F5OS-C

Symptoms:
The ETCD-HA instance may not initialize correctly after PXE-booting a system controller and re-installing that system controller into the openshift cluster. When the instance initializes incorrectly and one of the system controllers is down, the openshift API does not operate correctly.

Conditions:
PXE boot of a system controller in a running openshift cluster.

Impact:
When the instance initializes incorrectly and one of the system controllers is down, the openshift API does not operate correctly.

Workaround:
None

Fix:
Fixed the Ochestration-manager to correctly re-initialize the ETCD-HA instance when a system controller is PXE booted and the system controller is re-added into the openshift cluster.

1042253-1 : System controller upgrade from 1.2.0-10357 to 1.2.1-10301 intermittently fails★

Links to More Info: BT1042253

Component: F5OS-C

Symptoms:
The upgrade proceeds to the point where both system controllers boot to the new image but neither system controller becomes active.

Conditions:
Whenever this issue is observed, show full-configuration system redundancy config mode is something other than the default (auto).

Impact:
Neither system controller becomes active. The ability to configure the System controllers is compromised.

Workaround:
Restarting both Vcc-ConfD containers (or a reboot of both system controllers) should clear the problem.

Fix:
Intermittent loss of active system controller when upgrading from 1.2.0-10357 to 1.2.1-10301 is fixed in 1.2.1.

1041381 : Tcpdump capture may not include broadcast and multicast egress (generated by the system and being sent out) when "--dls true" option is used

Component: F5OS-C

Symptoms:
When DLS feature is turned on using "--dls true" option, broadcast and multicast packets generated by the host CPUs of the system and egressing out of the VELOS system will not be part of the capture.

The default mode when no "--dls" option is specified is "--dls false", which has no issue

Conditions:
The 'DLS' feature of tcpdump is turned on by explicitly invoking packet capture with the non-default mode "--dls true"

Impact:
Capture will not be complete and will not contain the egressing broadcast and multicast packets.

Workaround:
Use the default mode ( i.e no "--dls option specified) or explicitly turn off dls mode ("--dls false")

1039085 : Partition config restore operation can cause the system to stop processing fdbs.

Links to More Info: BT1039085

Component: F5OS-C

Symptoms:
In rare cases, a partition config-restore operation can cause a race condition that locks up a platform component. This causes fdbs to no longer be processed, and can affect traffic processing.

Conditions:
Issuing a config-restore operation on the partition cli. This issue is more likely to occur when the number of tenants increases.

Impact:
Fdbs will no longer be processed. Traffic processing can be impacted due to missing fdbs.

Workaround:
First, restart the network manager on both controllers:
    - "docker restart partition<partition_number>_network_manager"
Second, redeploy all tenants.

1038557-1 : Partition merged stats only reflect one blade when tmstat-rsync service moves to other blade

Component: F5OS-C

Symptoms:
A few show stats commands such as 'show qos state' that report stats for all blades in a partition could report only the stats from a single blade when the tmstat-rsync service moves from the blade is was on initially to another blade.

Conditions:
The tmstat-rsync service has moved to a blade other than the initial blade it was running on and a show command that combines stats from all the blades in a partition is run.

Impact:
A few show stats commands will only report data from a single blade.

Workaround:
Restart the tmstat-rsync service so it runs back on the initial blade.

1037749 : Switch daemon crashes occasionally on shutdown.

Links to More Info: BT1037749

Component: F5OS-C

Symptoms:
Shutting down the system sometimes causes the switch daemon to crash.

Conditions:
This occurs rarely during system shutdown.

Impact:
A core file is saved to /var/shared/core/container/.

Workaround:
None.

Fix:
This has been fixed in 1.2.2 and 1.3.

1037673 : Vcc-lacpd on a system controller can crash and leave a core file while restarting.

Links to More Info: BT1037673

Component: F5OS-C

Symptoms:
Vcc-lacpd on a system controller crashes, leaving behind a core file and a system log indicating a crash occurred. After the crash, the daemon recovers within a few seconds.

Conditions:
The crash only occurs during a restart of vcc-lacpd. Most commonly, a restart will occur during a system controller software update, using the "go-standby" command, or from a fatal error.

Impact:
The internal mgmt network to all blades may go down for a few seconds. Traffic running on tenants will be unaffected.

Workaround:
Limit failover scenarios on the system controllers, like use of the system controller "go-standby" command or system controller software updates.

Fix:
Vcc-lacpd no longer leaves a core file under these conditions.

1037525 : Some of the PCie AER severity and types are incorrect in the diagnostic monitoring.

Links to More Info: BT1037525

Component: F5OS-C

Symptoms:
Some of AER error type and severity events are displayed incorrectly in the diagnostics monitoring.

Conditions:
If an AER (Advanced Error Reporting) error occurs the decoding of the error type and severity as reported in the diagnostic could be incorrect.

Impact:
AER errors in diagnostic monitoring could be interpreted incorrectly as a 'Fatal' error.

Workaround:
As there is not a complete mitigation for this, the AER errors are correctly logged in the system logs and can be confirmed by timestamp and device to obtain the correct information

Fix:
Fixed an issue with incorrect diagnostics reporting.

1035353-1 : Missing controller images in show image controller CLI operation

Component: F5OS-C

Symptoms:
After software upgrade, the controller images in display of "show image controller" shows only active controller images. The standby controller images are missing in "show image controller" CLI command. This is very occasional and won't happen always.

Conditions:
Using CLI/RESTCONF command operations for show image controller

Impact:
User won't see the standby controller images in "show image controller"

Workaround:
The reboot of standby controller using the CLI operation "system reboot controllers controller standby" would resolve the issue and bring the controller images back into CLI display.

1034993-1 : Key-migrationd service can crash if server elements are incomplete

Component: F5OS-C

Symptoms:
The key-migrationd service crashes after defining some server-group information for radius/ldap servers.

Conditions:
After defining system->aaa->server-groups->server-group but not fully defining the item, and then attempting to read the item.

Impact:
Core file is created and key-migration malfunctions.

Workaround:
Remove the partially-defined server group or fully define all server-group items.

Fix:
The key-migration works without crashing.

1034481 : When using IPv6 on mgmt-floating and dhcp, it is possible to get different ip addresses on failover

Component: F5OS-C

Symptoms:
When running IPv6 and using dhcp to assign the mgmt-floating address, a chassis failover can cause the ip address to be changed.

Conditions:
Running IPv6, using dhcp for mgmt-floating and failing over a system controller. IPv4 is unaffected as is IPv6 statically assigned addresses.

Impact:
Services wont be available on mgmt-floating as expected until the user finds the interface on an unexpected IPv6 address

Workaround:
None

1034169 : Qkview reports status of "partial file recorded" when out of disk space

Component: F5OS-C

Symptoms:
When qkview attempts to create a qkview file and there is insufficient disk space, the status recorded is "partial file recorded". The actual cause is low disk space, and no qkview is collected in this case. The recorded status should indicate so.

Conditions:
Run the qkview collection with less than 1 GB of available disk.

Impact:
Cosmetic.

Fix:
The status now indicates: Out-of-disk. Unable to create Qkview file.

1033817 : GUI effected due to /api/data/f5-cluster:cluster/nodes/node taking more than 25 seconds to complete

Component: F5OS-C

Symptoms:
The 'show cluster nodes node' command takes more than 25 seconds to complete.

Conditions:
This happens on a chassis that is not fully populated.

Impact:
The get api /api/data/f5-cluster:cluster/ takes more time, resulting in slow page load times.

Workaround:
None

Fix:
Modified diag-agent partition to check the blade ready status before contacting it for disk-usage information. This is reduce the timeouts

1033813 : Partition 'show interfaces' command can be slow

Links to More Info: BT1033813

Component: F5OS-C

Symptoms:
A 'show interfaces' command or the corresponding RESTCONF API request that includes 'show interfaces interface state counters' or 'show interfaces interface ethernet state counters' can take a long time to execute.

Conditions:
If a blade was present in the partition, but is either physically removed or powered off, but the slot is not removed from the partition configuration.

If a 'show interfaces interface state counters' query is issued for an aggregate (trunk), a delay will also be observed.

Impact:
UI screen refresh is slow (2 to 8 seconds per missing blade), or the CLI 'show' command take a long time to return.

Workaround:
Use the system controller UI or CLI to remove the non-existent blade from the partition.

Fix:
Fixed an issue causing the show interfaces command to be slow when a blade is removed.

1032697 : File delete operation throws an improper message

Component: F5OS-C

Symptoms:
A file delete operation has a confusing error message:

syscon-1-active# file delete file-name log/host/ansible.log

Only /mnt/var/confd/configs/ /var/shared/ configs/ diags/shared/ paths are allowed for Delete file operation on Controller
ConfD.

Conditions:
Attempting a file delete operation from a directory which does not have delete permission

Impact:
The error message lists the actual paths along with the virtual paths on which delete is supported.

Workaround:
None

Fix:
On file delete operation, it only list virtual paths

1032341 : Confd Encryption key gets rewritten intermittently

Links to More Info: BT1032341

Component: F5OS-C

Symptoms:
The key should always return the same value and hash, unless it is changed via key-migration.

The reading of memory (EEPROM) will sometimes return "resource temporarily unavailable" which is treated as an error instead of simply doing a retry.

Conditions:
The EEPROM might be busy because of use by other components.

Impact:
The encryption key changes, thus invalidating all currently encrypted items, thus requiring re-entry of these.

Workaround:
The only workaround is to re-enter all encrypted items and hope that the "resource temporarily unavailable" does not occur.

Fix:
Fixed an issue where the system no longer considers "resource temporarily unavailable" as an error unless it happens 10 times in a row. The system does a retry and if that works, the system avoids setting a new key.

1029561 : GNOME GLib vulnerability CVE-2021-27219

Links to More Info: K82112489

1022729 : Management port issues with instance names containing lacpd, lldpd, stpd, or tmstat-rsync

Component: F5OS-C

Symptoms:
The management port stops working when instance names contain any of the following: lacpd, lldpd, stpd, or tmstat-rsync

Conditions:
Instances whose names include any of the following:
  lacpd
  lldpd
  stpd
  tmstat-rsync

Impact:
Management port no longer works.

Workaround:
Avoid naming instances using any of the following:
  lacpd
  lldpd
  stpd
  tmstat-rsync

Fix:
You can now successfully name instances using strings containing the following:
  lacpd
  lldpd
  stpd
  tmstat-rsync

1022589 : New blank blades inserted into system can wind up in a reboot loop and possibly be damaged

Component: F5OS-C

Symptoms:
Blades fresh from manufacturing do not contain an OS image. If not made part of a partition with an os image defined, when inserted, they will wind up in a continuous reboot loop. There is potential that this may cause damage to blade components if allowed to continue for an extensive period of time.

As systems shipped from factory include all slots in the default partition and that partition is set up with a partition image already configured, this condition should only be possible when blades are added in the field and the site has added partition definitions which do not have OS images set.

Conditions:
Freshly manufactured blade installed in a system slot which is not part of a partition with a defined iso image

Impact:
Potential drive media damage if the reboot loop is allowed to continue for an extended period of time.

Workaround:
Options to mitigate:
1--Install an OS image on the new blade
2--Power down the blade using AOM until ready to load an image

The simplest method to install an os image is to be sure the installation slot is part of a partition definition which includes a set os image. By default the blade will pxeboot that image.

1008549 : iHealth indicates multiple unhealthy and critical states for un-inserted PSUs.

Component: F5OS-C

Symptoms:
The component health for PSUs that are not inserted in the VELOS chassis is shown as unhealthy along with an iHealth critical severity.

Conditions:
This issue occurs on a VELOS chassis that has one or more PSUs not populated.

Impact:
The chassis health of these non-populated PSUs are shown has unhealthy in iHealth.

Fix:
Modified diag-agent service so that it does not mark an unhealthy state for PSUs that are not present in the chassis.

1008433 : VQF hot signal asserted warnings

Links to More Info: BT1008433

Component: F5OS-C

Symptoms:
A PEL log entry occurs indicating an FPGA HOT signal asserted:

Warning | AOM | 5 | Na | VQF hot thermal event

Conditions:
This issue happens at system startup.

Impact:
If the issue occurs during system startup, it is an erroneous error message and can be safely ignored.

Workaround:
Fixed an erroneous FPGA HOT signal that occurs during system startup.

1005025 : Orchestration-manager core on standby controller during cluster bringup.

Links to More Info: BT1005025

Component: F5OS-C

Symptoms:
A core file from orchestration-manager may be created on the standby switch during cluster bringup.

Conditions:
This may occur intermittently during cluster bringup.

Impact:
A core file is generated, but orchestration-manager will restart and will not cause any issues with system function.

Workaround:
None

1004049 : Show system mgmt-ip displays "Application Timeout" on the Active system controller

Component: F5OS-C

Symptoms:
On a system where the standby system controller is rebooting, running the 'show system mgmt-ip' command in confd can display an "Application Iimeout" error.

Conditions:
-- Standby system controller is rebooting.
-- The 'show system mgmt-ip' command is run in confd

Impact:
This problem is limited to system controller mgmt-ip only.

Workaround:
The command would fail very first time the command is executed while standby controller is rebooting. After it fails the first time, the command displays output in subsequent retries.

Fix:
The 'show system mgmt-ip' command now works while the standby system controller is rebooting.
