Miller" , Antonio Quartulli , Simon Wunderlich , Marek Lindner Subject: [PATCH] batman-adv: Fix mem leak in the batadv_tt_local_event() function Message-ID: User-Agent: Alpine 2.00 (LNX 1167 2008-08-23) MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1221 Lines: 38 Memory is allocated for 'tt_change_node' with kmalloc(). 'tt_change_node' may go out of scope really being used for anything (except have a few members initialized) if we hit the 'del:' label. This patch makes sure we free the memory in that case.
