patch 'test/crypto: fix wireless auth digest segment' has been queued to stable release 21.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/14/22. 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/627efa19b562edc73df7ece42a075f3425102400

Thanks.

Kevin

Subject: [PATCH] test/crypto: fix wireless auth digest segment

[ upstream commit dc3f6c5347b2b64899694c2f94a6af53c95d2b4d ]

The segment size for some tests was too small to hold the auth digest.
This caused issues when using op->sym->auth.digest.data for comparisons
in AESNI_MB PMD after a subsequent patch enables SGL.

For example, if segment size is 2, and digest size is 4, then 4 bytes
are read from op->sym->auth.digest.data, which overflows into the memory
after the segment, rather than using the second segment that contains
the remaining half of the digest.

Fixes: 11c5485bb276 ("test/crypto: add scatter-gather tests for IP and OOP")
