patch 'net/ice: fix memory leak in raw pattern parse' has been queued to stable release 22.11.11

[luca.boccassi@gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/25. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/10383a47db49bcb93f0ef91aa46abee9f306fd5c

Thanks.

Luca Boccassi

Subject: [PATCH] net/ice: fix memory leak in raw pattern parse

[ upstream commit 3938eeec989181216ea3f9cc8eee931a2915ca5d ]

Currently, when parsing rte_flow raw type items, we allocate some
internal structures, but if errors happen down the line we just quit and
never free the memory we just allocated. Fix this by adding an error
cleanup section.

Fixes: 848de9572c83 ("net/ice: fix raw flow input pattern parsing")
