Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/17/25. 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/15e631a10c0bbede23f35f4a173822e768ed6b2b

Thanks.

Kevin

Subject: [PATCH] crypto/dpaa2_sec: fix bitmask truncation

[ upstream commit 013ddc85bff5fdb85eb6006315ebdaa0c12eeece ]

The dqrr_held mask is 64 bit but updates were getting truncated
because 1 is of type int (32 bit) and the result shift of int is of
type int (32 bit); therefore any value >= 32 would get truncated.

Fixes: a77db24643b7 ("crypto/dpaa2_sec: support atomic queues")
