patch 'net/ixgbe: fix potential null dereference with IPsec config' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/02/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/4ec817f11296130aaec71da42db0228cf0160682

Thanks.

Kevin

Subject: [PATCH] net/ixgbe: fix potential null dereference with IPsec config

[ upstream commit eb3de5f328afbff3a1abd2184052355b4fe4a981 ]

When parsing IPsec flows, we access the `conf` pointer unconditionally,
even though it might be NULL. Fix by adding the check.

Fixes: 9a0752f498d2 ("net/ixgbe: enable inline IPsec")
