Subject: patch 'net/mlx5: restrict Rx queue array access to boundary' has been queued to stable release 21.11.2

Message-ID: <20220510123010.159523-15-ktraynor@redhat.com> (raw)

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/15/22. 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/b3896dba13eae6b410733af101a80b403a474416

Thanks.

Kevin

Subject: [PATCH] net/mlx5: restrict Rx queue array access to boundary

[ upstream commit 1573b07284caf92cad5479b539213c508d5583a6 ]

The mlx5_rxq_get() function gets RxQ index and return RxQ priv
accordingly.

When it gets an invalid index, it accesses out of array bounds which
might cause undefined behavior.

This patch adds a check for invalid indexes before accessing to array.

Fixes: 0cedf34da78f ("net/mlx5: move Rx queue reference count")
