991061-2 : Admin cannot edit the tenant config in Deployed state from GUI if the tenants are created via CLI; downgrading partition or rSeries appliance may leave device inoperative

Links to More Info: BT991061

Component: F5OS-A

Symptoms:
Trying to modify a tenant via the GUI or API may not work if the tenant was created via the CLI, and is deployed.

Attempting to downgrade an rSeries appliance from F5OS-A 1.1.0 or above to F5OS-A 1.0.x may fail if the device has any tenants deployed. This leaves the system inoperative, with errors similar to the following in /var/F5/system/log/confd.log:

<CRIT> 5-Jun-2022::03:17:21.056 appliance-1 confd[105]: - CDB: Upgrade failed: Upgrade transaction failed to validate: /f5-tenants:tenants/tenant{otters}/config/storage/size (value "90"): Storage size can be modified only if tenant is in Configured or Provisioned state.

Attempting to downgrade an F5OS-C partition from F5OS-C 1.3.0 or above to F5OS-C 1.2.1 or below may fail if the partition has any tenants deployed. The partition should continue running on the "from" target version.

Conditions:
Admin creates the tenant via CLI and subsequently edits the following tenant config when the running-state is set to Deployed:

-- Scale-up/Scale-down the tenant.
-- Add/Remove VLAN.

Impact:
Admin cannot scale up/scale down the cluster using the GUI if the tenant is initially deployed via CLI.

Downgrades of F5OS-A appliance or F5OS-C partition may fail or leave the system inoperative.

Workaround:
Use the CLI to scale-up/scale-down and add/remove the VLAN to the tenant.

When performing a downgrade, set the tenants to Provisioned first.

Component: F5OS-A

Symptoms:
When an LACP trunk is configured on an F5OS chassis/appliance and only the native VLAN is attached, the LACP trunk will not be automatically configured on the BIG-IP tenant.

Conditions:
This behavior is observed only when the LACP trunk is attached to a native VLAN.

Impact:
LACP trunk configuration will not be applied to the BIG-IP tenant automatically when only a native VLAN is attached to it on the platform.

Workaround:
Configure the LACP trunk in the BIG-IP tenant manually.

Fix:
LACP trunks are now configured automatically in BIG-IP tenant running on F5OS chassis/appliances, as expected.

1080417 : List of running containers are not captured in host qkview

Links to More Info: BT1080417

Component: F5OS-A

Symptoms:
List of running containers are not captured in host qkview

Conditions:
Collect qkview and look for list of containers running on the system from qkview file.

Impact:
Unable to get the list of running containers from qkview

Workaround:
Administrator needs to run 'docker ps' command on the system and share the output with support.

Fix:
Qkview includes list of running containers on the system

1080109-1 : System reboot or link down/up transition causes packet loss.

Component: F5OS-A

Symptoms:
A reboot of the system or a link down/up transition can result in packet loss on the affected front-panel interface(s).

Conditions:
A link down->up transition on a front panel interface or interfaces. Either initiated from the peer side or a system reboot.

Impact:
LACP LAGs can fail to form. Ingress traffic is not received by the tenants.

Workaround:
Reboot the system.

Fix:
Change link down processing to not reset internal hardware state of front panel MACs.

1079697 : Incorrect link aggregation group (LAG) / trunk information passed to tenant.

Component: F5OS-A

Symptoms:
A BIG-IP tenant running on a VELOS system incorrectly reports all "ha-only" trunk objects as up, regardless of the actual status of the trunk.

BIG-IP tenants can also report incorrect status of trunks after the LAG type is changed from LACP to STATIC or vice-versa.

An interface name is displayed as empty when an interface is deleted from a LAG.

As a result of these, high availability (HA) group failover based on trunk status is unreliable and unusable.

Conditions:
-- LAGs configured on F5OS system.
-- Attempting to use high availability (HA) group failover based on trunk status inside BIG-IP tenant.

Impact:
HA group failover based on trunk status is unreliable and unusable for BIG-IP tenants running on an F5OS system.

Workaround:
After configuring a new LAG in the the F5OS partition or changing a LAG type from LACP to STATIC or from STATIC to LACP, reboot the traffic blades.

For rSeries devices, the entire device must be restarted.

After rebooting, the ha-group trunk entries should show the expected values when one or more members are missing from the aggregate link.

Fix:
This issue has been corrected.

1078633 : Tenant to API gateway communication and unit-key will not work after key rotation

Component: F5OS-A

Symptoms:
The system-api-svc-gateway fails to decrypt the unit key crashes, and is unable to communicate with the tenant.

Conditions:
A key migration or rotation is performed in confd: system aaa primary-key

Impact:
Communication between the API gateway and the tenant is disrupted.

Note: If no key-rotation was ever done, this issue does not occur.

Workaround:
To correct the current unit-key issue, invoke the config command:
system database reset-to-default proceed yes


To avoid the issue, disable key-rotation. To prevent key rotation, add the line '/tenants/tenant{%x}/config/unit-key' to the file in the confd-key-migration-mgr container:
/tenants/tenant{%x}/config/unit-key

To do so: ssh as root into the device and do the following:

# docker exec -it confd-key-migration-mgr bash
bash-4.2# echo "/tenants/platform-self-signed-cert/self-signed-key" >> /etc/confd-key-migration/appliance-secure-elem-manifest
bash-4.2# echo "/tenants/tenant{%x}/config/unit-key" >> /etc/confd-key-migration/appliance-secure-elem-manifest
bash-4.2# exit
# docker restart confd-key-migration-mgr

Fix:
The system now adds the line to the manifest file.

Because the unit-key does not get re-encrypted with the new key, after upgrading to a software version containing the fix, run the config command:
system database reset-to-default proceed yes

1078149 : Unable to deploy one tenant when user attempts to deploy 28 tenants on r10800

Component: F5OS-A

Symptoms:

-- You attempt to deploy 28 tenants
-- Each tenant has only 1 vCPU

Impact:
28th tenant is not deployed on r10800.
The max supported tenants on r10800 is 28

1077785 : STP errors messages reported in platform.log when global STP is enabled but STP parameters are not configured in interfaces

Component: F5OS-A

Symptoms:
The VELOS platform.log contains numerous STP error messages:

appliance-1 stpd[1]: priority="Err" version=1.0 msgid=0x6102000000000018 msg="Failed to write to cdb" FIELD="Adv Stp Interface name" ERRNO=8 ERRNOSTR="badly formatted or nonexistent path".
appliance-1 stpd[1]: priority="Err" version=1.0 msgid=0x6102000000000018 msg="Failed to write to cdb" FIELD="Adv Stp Interface port-num" ERRNO=8 ERRNOSTR="badly formatted or nonexistent path".
appliance-1 stpd[1]: priority="Err" version=1.0 msgid=0x6102000000000018 msg="Failed to write to cdb" FIELD="Adv Stp Interface port-state" ERRNO=8

Conditions:
The following is the correct sequence of STP configuration.

appliance-1(config)# stp global config enabled-protocol RSTP
appliance-1(config)# stp rstp interfaces interface 1.0 config cost 100;top
appliance-1(config)# stp interfaces interface 1.0 config edge-port EDGE_AUTO link-type P2P ;
appliance-1(config-interface-1.0)# exit
appliance-1(config)# commit;

If the command "stp rstp interfaces interface 1.0 config cost 100;top" is not run, the log messages will occur.

Impact:
VELOS platform.log size will grow at rate of 2MB per minute.

Workaround:
To stop these messages, configure the following:

stp rstp interfaces interface 1.0 config cost 100;top

Fix:
Multiple STP errors messages are no longer logged when not needed.

1074381 : Invalid error message in log when 40g transceiver is inserted

Symptoms:
the k3s_events.log file is not rotated.

Conditions:
K3s provisioning from the OMD is initiated.

Impact:
Most of the system memory is consumed by k3s_events.log and system starts responding slowly.

Workaround:
Manually empty the contents of /var/log/k3s_events.log file from the system.

1069529-2 : "Appliance Mode" UI control intermittently will revert your selection back to its configured state when enabling or disabling.

Component: F5OS-A

Symptoms:
On the SYSTEM SETTINGS/General screen for the rSeries appliance, the "Appliance Mode" Enable/Disable radio button choice will revert back to its configured state when you're attempting to change the configuration prior to saving it.

Conditions:
The Enable/Disable radio button for Appliance Mode will undo your preferred selection when the screen does a periodic poll in the background to refresh state information that is displayed on the SYSTEM SETTINGS/General screen.

Impact:
If you attempt to either enable or disable Appliance Mode and the screen does a periodic polling refresh at the moment you make your desired selection, your selection will be reverted back to the actual current configuration state for Appliance Mode.

Workaround:
The impact is intermittent and only occurs at the precise moment the screen is refreshing its state information --- typically a 10 second interval. Appliance Mode can still be enabled or disabled via the webUI as long as it is within the window the screen is not doing a periodic refresh. Additionally, Appliance Mode can be enabled or disabled from the command line interface (CLI).

Fix:
Periodic polling on the SYSTEM SETTINGS/General screen for rSeries appliances will be disabled or removed.

1069209-1 : LAG names starting with a digit

Component: F5OS-A

Symptoms:

1066869-1 : The r10000 and r5000 platforms may reuse the MAC address for both management and data plane.

Component: F5OS-A

Symptoms:
The MAC address assigned to the macvlan interface mgmt0-system may also be assigned to a dataplane object: a lag or a tenant.

Conditions:
More than 233 lags or tenants are configured on a r10000 or r5000 platforms.

Impact:
If the management interface mgmt0-system and the lag or tenant are on the same broadcast domain, both devices will have communication problems. Duplicate MACs going to different switches will be fine.

Workaround:
The MAC address that will be duplicated is 0xfc offset from the basemac. If a tenant or lag has been assigned basemac+0xfc remove the tenant or lag, reduce the number of lags + tenants to less than 252, then re-create the tenant or lag - checking to make sure the assigned MAC does not use offset 0xfc from the base MAC.

Fix:
The pool of available MAC addresses to be used for tenants or lags on r10000 and r5000 platforms has been reduced from 236 to 233 to ensure unique MACs are supplied for all interfaces, lags and tenants.

1046221-2 : SM2 cannot be used for creating self-signed certificates

Component: F5OS-A

Symptoms:
When creating a self-signed certificate, VELOS returns an error.

The create self-signed certificate function allows for elliptic curves but does not work for 'SM2'.

Conditions:
When requesting a certificate using type ec, the curve name SM2 can be selected.

Impact:
Attempting to use SM2 curve name results in an error.

Workaround:
Outside confd you can create the SM2 key using:
/usr/bin/openssl ecparam -genkey -name SM2

The key can then be entered using system-aaa-tls-config-key and subsequently used to create a CSR.

The self-signed certificate would need to be done using openssl commands and entered manually if to be stored.

Fix:
The SM2 curve name can now be used like all the other ec curve names.

Conditions:
Enable DHCP on the management interface from confd

Impact:
DNS server IPs fetched dynamically by the DHCP server are not displayed by confd

Workaround:
None

Fix:
Fixed code to update confd with DNS server IP addresses when DHCP is enabled on the management interface

Links to More Info: BT1012437

Component: F5OS-A

Symptoms:
A VELOS tenant's virtual-disk is deleted when the tenant running-state is set back to "configured" after having been "deployed." This behavior differs from vCMP.

It is recommended that you set the tenant running-state to "provisioned" in order to stop the running tenant.

Conditions:
Tenant running-state changed from "deployed" to "configured."

Impact:
Virtual disk is deleted, resulting in loss of tenant configuration.

Workaround:
Fixed. No workaround needed.

Fix:
The system no longer deletes the virtual disk when the state is changed from deployed to configured.
