patch 'vhost/crypto: fix cipher data length' has been queued to stable release 23.11.5

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/28/25. 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://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=9a1e04684ee6cf840d9eff4bd41938d46bcc2759

Thanks.

Subject: [PATCH] vhost/crypto: fix cipher data length
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 7ccd67c4185e1f4f0b975ff954e8685252bc3a18 ]

This patch fixes cipher data length, in the event of algorithm
chaining. When enqueuing crypto op to vhost backend
cipher.data.length is set correctly which is in
virtqueue_crypto_sym_pkt_header_arrange(). This field is computed
and assigned wrongly instead of using passed value. This is
rectified and using correct cipher data length in vhost crypto.

Fixes: 3bb595ecd682 ("vhost/crypto: add request handler")
