Message-Id: <20130201104724.929879262@linuxfoundation.org> Date: Fri, 1 Feb 2013 11:49:09 +0100 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Cong Ding <dinggnu@...il.com>, Jeff Layton <jlayton@...hat.com>, Steve French <smfrench@...il.com> Subject: [ 04/33] fs/cifs/cifs_dfs_ref.c: fix potential memory leakage 3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Cong Ding <dinggnu@...il.com> commit 10b8c7dff5d3633b69e77f57d404dab54ead3787 upstream. When it goes to error through line 144, the memory allocated to *devname is not freed, and the caller doesn't free it either in line 250. So we free the memroy of *devname in function cifs_compose_mount_options() when it goes to error.
