Subject: [B.A.T.M.A.N.] [PATCH 1/3] batman-adv: fix skb leak in batadv_dat_snoop_incoming_arp_reply()
Date: Sun, 27 Jan 2013 20:43:57 +0100 [thread overview]
Message-ID: <1359315839-24136-2-git-send-email-ordex@autistici.org> (raw)
In-Reply-To: <1359315839-24136-1-git-send-email-ordex@autistici.org>
From: Matthias Schiffer <mschiffer@universe-factory.net>
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().
