From 977d8c6f9253ad71e4bd8e4be2705c3bee684feb Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Wed, 23 Jan 2013 18:11:53 +0100 Subject: [PATCH 1/4] batman-adv: fix skb leak in batadv_dat_snoop_incoming_arp_reply() The callers of batadv_dat_snoop_incoming_arp_reply() assume the skb has been freed when it returns true; fix this by calling kfree_skb before returning as it is done in batadv_dat_snoop_incoming_arp_request().
