octeontx2-pf: Fix potential use after free in otx2_tc_add_flow()

2025-09-25T09:04:34+00:00

This code calls kfree_rcu(new_node, rcu) and then dereferences "new_node" and then dereferences it on the next line. Two lines later, we take a mutex so I don't think this is an RCU safe region. Re-order it to do the dereferences before queuing up the free.

libie: fix string names for AQ error codes

2025-09-24T23:58:54+00:00

The LIBIE_AQ_STR macro() introduced by commit 5feaa7a07b85 ("libie: add adminq helper for converting err to str") is used in order to generate strings for printing human readable error codes. Its definition is missing the separating underscore ('_') character which makes the resulting strings difficult to read. Additionally, the string won't match the source code, preventing search tools from working properly. Add the missing underscore character, fixing the error string names.

net/mlx5: HWS, ignore flow level for multi-dest table

2025-09-24T00:17:30+00:00

When HWS creates multi-dest FW table and adds rules to forward to other tables, ignore the flow level enforcement in FW, because HWS is responsible for table levels.

net/mlx5: fs, fix UAF in flow counter release

2025-09-24T00:17:30+00:00

Fix a kernel trace [1] caused by releasing an HWS action of a local flow counter in mlx5_cmd_hws_delete_fte(), where the HWS action refcount and mutex were not initialized and the counter struct could already be freed when deleting the rule. Fix it by adding the missing initializations and adding refcount for the local flow counter struct.

bnxt_en: correct offset handling for IPv6 destination address

2025-09-23T00:56:39+00:00

In bnxt_tc_parse_pedit(), the code incorrectly writes IPv6 destination values to the source address field (saddr) when processing pedit offsets within the destination address range. This patch corrects the assignment to use daddr instead of saddr, ensuring that pedit operations on IPv6 destination addresses are applied correctly.

i40e: improve VF MAC filters accounting

2025-09-18T22:46:30+00:00

When adding new VM MAC, driver checks only *active* filters in vsi->mac_filter_hash. Each MAC, even in non-active state is using resources. To determine number of MACs VM uses, count VSI filters in *any* state. Add i40e_count_all_filters() to simply count all filters, and rename i40e_count_filters() to i40e_count_active_filters() to avoid ambiguity.
