Subject: [PATCH] ip_gre: remove an extra dst_release()
Date: Tue, 19 Feb 2013 14:14:10 -0800 [thread overview]
Message-ID: <1361312050.19353.169.camel@edumazet-glaptop> (raw)
From: Eric Dumazet <edumazet@google.com>
commit 68c331631143 (v4 GRE: Add TCP segmentation offload for GRE)
introduced a bug in error path.
dst is attached to skb, so will be released when skb is freed.
