From 2ab957492d13bb819400ac29ae55911d50a82a13 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Sebastian=20P=C3=B6hn?= Date: Mon, 20 Apr 2015 09:19:20 +0200 Subject: [PATCH] ip_forward: Drop frames with attached skb->sk Initial discussion was: [FYI] xfrm: Don't lookup sk_policy for timewait sockets Forwarded frames should not have a socket attached. Especially tw sockets will lead to panics later-on in the stack. This was observed with TPROXY assigning a tw socket and broken policy routing (misconfigured). As a result frame enters forwarding path instead of input. We cannot solve this in TPROXY as it cannot know that policy routing is broken. v2: Remove useless comment Signed-off-by: Sebastian Poehn Signed-off-by: David S.
