4369312

Description: Fixed an issue where the mlnx_tune -l command did not list several operating systems that were in fact supported.

Keyword: mlnx_tune, OSes

Detected in version: 3.0.0

4172481

Description: The kernel does not define TCA_TUNNEL_KEY_ENC_SRC_PORT. To align offload behavior with non-offload, the OVS community introduced a commit [1] that causes offload to fail if this tunnel attribute is used. Now, any rule with a tunnel set action that includes a tunnel source port can no longer be offloaded.

[1] netdev-offload-tc: Fix offload of tunnel key tp_src.

Keyword: Tunnel source port offload

Detected in version: 3.0.0

4375188

Description: Upstream kernel 6.11 introduced support for encapsulation control flags, which was also added in OVS 3.5.0. However, current hardware does not support matching on these flags, such as "don't fragment" and "checksum." Since these flags can be safely ignored, we reverted upstream commit [1] as a workaround to restore tunnel offload functionality.

[1] net/mlx5e: flower: validate encapsulation control flags

Keyword: Encapsulation control flags, tunnel offload

Detected in version: 3.0.0

4340654

Description: Fixed an issue where LLDP traffic from VFs or BF host PFs was not reaching the representor kernel interfaces.

Keyword: LLDP packets

Detected in version: 2.8.0, 2.9.0

4304103

Description: Flows where both the inner and outer destination (dst) and/or source (src) MAC addresses were rewritten to the same value, the outer MAC address rewrite was ignored, leading to an outer MAC address of 00:00:00:00:00:00. This issue has been fixed.

Keyword: MAC addresses

Detected in version: 2.4.0

4264397

Description: OVS does not forward IPv6 Neighbor Advertisements with unicast destination MAC addresses to the CPU. This means the endpoint MAC address may not be learned on the VTEP if the endpoint is silent, causing traffic to be software forwarded. After the endpoint initiates traffic, it will be hardware forwarded. The issue persists only if the endpoint never initiates any traffic, only responding to IPv6 Neighbor Solicitations (rare). This issue has been fixed.

Keyword: Neighbor Advertisements, Neighbor Solicitations, OVS

Detected in version: 2.10.0

4186679

Description: Fixed an issue where enabling sFlow with OVN caused OVS to crash.

Keyword: sFlow

Detected in version: 2.9.2

4150662

Description: Fixed an issue where OVS crashed unexpectedly after DPUs repeatedly broadcast the error message “packet with own source address.”

Keyword: OVS, DPUs

Detected in version: 2.7

4242133

Description: Fixed an issue where changing the hw-offload setting from true to false while ports are configured could lead to errors reported in the OVS log.

Keyword: OVS

Detected in version: 2.10

4945554

Description: If a secondary BMC task (such as a log dump) is started after the BMC firmware update has been initiated, but before the installer's monitoring logic has attached to it, the installer may mistakenly track the secondary task. This tracking error causes the installer to misjudge the update's completion, which can cause the subsequent BMC reboot to fail and leave the new firmware in a pending, unactivated state.

Keywords: BFB installer; Redfish API; task monitoring

Detected in version: 4.14.0

4863927

Description: When attempting to install development packages via dnf on Rocky Linux 9.2, users may encounter a package repository inconsistency. This version mismatch results in a dependency resolution failure, preventing the installation of the packages.
