Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/769a37361a56283464eafda725147c5c6874043a

Thanks.

Luca Boccassi

Subject: [PATCH] net/bnxt: validate direction index in TPM table

[ upstream commit b046a64156c2139bca071bf6a29da03050385078 ]

Validate the direction in cfa_tim_tpm_inst_set() and
cfa_tim_tpm_inst_get() so that a direction taken from a VF2PF
message cannot index past the table scope instance manager's TPM
table. The tsid and region inputs were already range checked.

Fixes: 80317ff6adfd ("net/bnxt/tf_core: support Thor2")
