patch 'net/enic: fix null dereference in flow mask check' has been queued to stable release 24.11.7

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/15/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/ab89db9d9fd50d0a810ed0aea3b9d831c79decc2

Thanks.

Luca Boccassi

Subject: [PATCH] net/enic: fix null dereference in flow mask check

[ upstream commit 1e267033c1f67cf7ed6f01d449297ff88f3e341d ]

The functions enic_copy_item_ipv4_v1(), enic_copy_item_udp_v1(), and
enic_copy_item_tcp_v1() each initialize a local 'mask' variable from
item->mask and substitute it with a hardcoded mask if NULL. However,
the subsequent mask_exact_match() call uses item->mask directly
instead of the local 'mask' variable, which will dereference NULL
when item->mask is NULL.

Use the local 'mask' variable (which has been validated and possibly
substituted) instead of item->mask.

Fixes: aa3d2ff82198 ("net/enic: flow API for Legacy NICs")
