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/35eb0fbaa1a9162038d4d111419a5207d4078c10

Thanks.

Subject: [PATCH] net/bnxt/tf_ulp: fix tunnel list memory corruption

[ upstream commit 57c816b0841241de463eb43480ddbc4033c6f352 ]

In ulp_app_tun_search_entry(), when a matching tunnel entry is found
at index i, the reference count was incremented on
tun_ent_list[free_entry] instead of tun_ent_list[i]. free_entry is -1
when no unused slot precedes the match (always the case when the table
is full), so this wrote before the start of the array; otherwise it
bumped the count of an unused slot and left the matched entry's count
unchanged. Use the matching index.

Fixes: bdf4a3c6316b ("net/bnxt: support tunnel offload")
