Subject: [PATCH AUTOSEL 5.4 25/26] net/mlx4_core: fix a memory leak bug.
Date: Thu, 28 May 2020 07:56:53 -0400	[thread overview]
Message-ID: <20200528115654.1406165-25-sashal@kernel.org> (raw)
In-Reply-To: <20200528115654.1406165-1-sashal@kernel.org>

From: Qiushi Wu <wu000273@umn.edu>

[ Upstream commit febfd9d3c7f74063e8e630b15413ca91b567f963 ]

In function mlx4_opreq_action(), pointer "mailbox" is not released,
when mlx4_cmd_box() return and error, causing a memory leak bug.
Fix this issue by going to "out" label, mlx4_free_cmd_mailbox() can
free this pointer.

Fixes: fe6f700d6cbb ("net/mlx4_core: Respond to operation request by firmware")
