From bd8a7036c06cf15779b31a5397d4afcb12be81ea Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Mon, 24 Jun 2013 06:26:00 -0700 Subject: gre: fix a possible skb leak commit 68c331631143 ("v4 GRE: Add TCP segmentation offload for GRE") added a possible skb leak, because it frees only the head of segment list, in case a skb_linearize() call fails. This patch adds a kfree_skb_list() helper to fix the bug. Signed-off-by: Eric Dumazet Cc: Pravin B Shelar Cc: Daniel Borkmann Signed-off-by: David S.
