From 6651ffc8e8bdd5fb4b7d1867c6cfebb4f309512c Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 21 Apr 2010 00:47:15 -0700 Subject: [PATCH] ipv6: Fix tcp_v6_send_response transport header setting. My recent patch to remove the open-coded checksum sequence in tcp_v6_send_response broke it as we did not set the transport header pointer on the new packet. Actually, there is code there trying to set the transport header properly, but it sets it for the wrong skb ('skb' instead of 'buff'). This bug was introduced by commit a8fdf2b331b38d61fb5f11f3aec4a4f9fb2dedcb ("ipv6: Fix tcp_v6_send_response(): it didn't set skb transport header") Signed-off-by: Herbert Xu Signed-off-by: David S.
