Subject: patch 'net/hns3: fix memory leak for indirect flow action' has been queued to stable release 22.11.9
Date: Thu, 12 Jun 2025 22:06:47 +0100 [thread overview]
Message-ID: <20250612210733.2506558-30-luca.boccassi@gmail.com> (raw)
In-Reply-To: <20250612210733.2506558-1-luca.boccassi@gmail.com>
Hi,
FYI, your patch has been queued to stable release 22.11.9
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/14/25. 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/399fda81668431073978e0d58f98ea4e36996648
Thanks.
Luca Boccassi

Subject: [PATCH] net/hns3: fix memory leak for indirect flow action
[ upstream commit 18596f7be8f93e159e98704af12b1cc8af289dd6 ]
Currently, when the application creates an indirect action,
the hns3 driver allocates a memory for the structure
rte_flow_action_handle and returns this structure pointer to
application. When the application invokes the destroy function
to destroy the indirect action, the driver releases the memory.
However, when the application destroys all flows by using the
flush function before destroying the indirect action, the memory
is not released. This patch fix it by using uint64_t instead of
rte_flow_action_handle* to store indirect action avoids memory
leakage.
Fixes: fdfcb94d8fb3 ("net/hns3: support indirect counter flow action")
