Keywords: mlxconfig

Discovered in Version: 22.38.1002

Fixed in Release: 22.39.2048

3666583

Description: Fixed a risk condition that occurred due to the descriptor length dynamic change in the new kernel version upon firmware termination of the WQE segment on a WQE when the "SUSPEND VIRTQ with Mergeable Buffer" capability was set.

Keywords: vDPA

Discovered in Version: 22.38.1002

Fixed in Release: 22.39.2048

Internal Ref.

Issue

3606330

Description: Modified the TCP IPv4 flows so that the steering TIR rx_hash_symmetric field is now valid only when both the SRC and DST fields are not set to zero.

Keywords: TCP IPv4 flows

Discovered in Version: 22.38.1002

Fixed in Release: 22.39.1002

3602169

Description: Added a locking mechanism to protect the firmware from a race condition between insertion and deletion of the same rule in parallel. Such behavior occasionally resulted in firmware accessing a memory that has already been released, thus causing IOMMU / translation error.

Note: This fix will not impact insertion rate for tables owned by SW steering.

Keywords: Firmware steering

Discovered in Version: 22.38.1002

Fixed in Release: 22.39.1002
