patch 'net/ice: fix memory leak in DCF QoS bandwidth config' has been queued to stable release 24.11.5

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/22/26. 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/b2d577314f28e8b3727266f4a7906668cef095f3

Thanks.

Luca Boccassi

Subject: [PATCH] net/ice: fix memory leak in DCF QoS bandwidth config

[ upstream commit efd5d15a886b51f8abd2315d5666cdd78814212a ]

Currently, when committing DCF QoS bandwidth configuration for VFs and
TCs, we are using rte_zmalloc followed by copying the data to persistent
storage and then discarding the temporary buffers. This is not needed as
these temporary buffers are not being stored anywhere, so replace them
with regular calloc. However, because the original code was missing a
corresponding `rte_free()` call for these temporary allocations, this
also fixes a memory leak.

Fixes: 3a6bfc37eaf4 ("net/ice: support QoS config VF bandwidth in DCF")
