Date: Mon, 1 Jun 2020 19:53:17 +0200 Message-Id: <20200601174023.607170777@linuxfoundation.org> X-Mailer: git-send-email 2.26.2 In-Reply-To: <20200601174020.759151073@linuxfoundation.org> References: <20200601174020.759151073@linuxfoundation.org> User-Agent: quilt/0.66 MIME-Version: 1.0 Sender: stable-owner@vger.kernel.org Precedence: bulk List-ID: X-Mailing-List: stable@vger.kernel.org From: Qiushi Wu commit febfd9d3c7f74063e8e630b15413ca91b567f963 upstream. 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.
