patch 'net/iavf: reset security context pointer on stop' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/06/22. 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/a42a8745993eb2627c6b60406e25de6926037627

Thanks.

Kevin

Subject: [PATCH] net/iavf: reset security context pointer on stop

[ upstream commit 23abab4f14d3e2425e74c296769d21b79d696096 ]

When iavf_security_ctx_destroy() is cleaning up, it does not correctly
set the security_ctx variable to NULL, which will lead to wild pointer.

Fixes: 6bc987ecb860 ("net/iavf: support IPsec inline crypto")
