[dpdk-stable] patch 'app/crypto-perf: fix AAD template copy overrun' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/12/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/2c8268b307e45be2a6dc8137e55b5e8389a4ca89

Thanks.

Subject: [PATCH] app/crypto-perf: fix AAD template copy overrun
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 49c19c94dc67a3db2f8534a1e6ca253e1f08fff7 ]

This patch fixes a possible buffer overrun problem in crypto perf test.
Previously when user configured AAD size is over 12 bytes the copy
of template AAD will cause a buffer overrun.
The problem is fixed by only copy up to 12 bytes of AAD template.

Fixes: 8a5b494a7f99 ("app/test-crypto-perf: add AEAD parameters")
