patch 'cryptodev: validate crypto callbacks from next node' 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=9b3e2355812ed4d6fc82b74ceaad30914df0aea2

Thanks.

Subject: [PATCH] cryptodev: validate crypto callbacks from next node
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit e858d0c9612211ba43d6703cb7834697214a3fe1 ]

Crypto callbacks are invoked on checking from head node
which is always valid pointer.

This patch checks next node from the head node if callbacks
registered before invoking callbacks.

Fixes: 1c3ffb95595e ("cryptodev: add enqueue and dequeue callbacks")
