Subject: [PATCH v2] net/mlx4_core: fix a memory leak bug.
Date: Fri, 22 May 2020 14:07:15 -0500 [thread overview]
Message-ID: <20200522190715.29022-1-wu000273@umn.edu> (raw)
From: Qiushi Wu <wu000273@umn.edu>
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")
Signed-off-by: Qiushi Wu <wu000273@umn.edu>
