Date: Wed, 22 May 2013 14:40:47 +0300 From: Timo Teräs <timo.teras@....fi> To: netdev@...r.kernel.org Cc: Timo Teräs <timo.teras@....fi>, Li RongQing <roy.qing.li@...il.com>, Steffen Klassert <steffen.klassert@...unet.com> Subject: [PATCH ipsec] xfrm: properly handle invalid states as an error The error exit path needs err explicitly set. Otherwise it returns success and the only caller, xfrm_output_resume(), would oops in skb_dst(skb)->ops derefence as skb_dst(skb) is NULL. Bug introduced in commit bb65a9cb (xfrm: removes a superfluous check and add a statistic).
