patch 'crypto/dpaa_sec: fix IPsec descriptor' has been queued to stable release 23.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/14/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=6e2def6ca9a6b1131b9efaf5ce913e7110459883

Thanks.

Subject: [PATCH] crypto/dpaa_sec: fix IPsec descriptor
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 046341575bd6e1210d6c12b595405ede41150da7 ]

During IPsec operations, driver code pre-check
whether KEYS can be inlined to limited size descriptor
or not and based on that it decides to copy the complete
KEY in descriptor or just give the memory pointer of
KEY in descriptor.
This pre-check code does not take care of padding required
for security engine to make the KEYs inline which results
in incorrect length descriptor for some algorithms.

This patch fixes this issue by updating the pre-check code
with proper padding size included for each supported
algorithm.

Fixes: 453b9593a3cf ("crypto/dpaax_sec: fix inline query for descriptors")
