2013-10-01ip_tunnel_core: Change __skb_push back to skb_pushSteffen Klassert
Git commit 0e6fbc5b ("ip_tunnels: extend iptunnel_xmit()") moved the IP header installation to iptunnel_xmit() and changed skb_push() to __skb_push(). This makes possible bugs hard to track down, so change it back to skb_push().

2013-09-04tunnels: harmonize cleanup done on skb on xmit pathNicolas Dichtel
The goal of this patch is to harmonize cleanup done on a skbuff on xmit path. Before this patch, behaviors were different depending of the tunnel type. Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2013-08-13ip_tunnel: Do not use inner ip-header-id for tunnel ip-header-id.Pravin B Shelar
Using inner-id for tunnel id is not safe in some rare cases. E.g. packets coming from multiple sources entering same tunnel can have same id. Therefore on tunnel packet receive we could have packets from two different stream but with same source and dst IP with same ip-id which could confuse ip packet reassembly. Following patch reverts optimization from commit 490ab08127 (IP_GRE: Fix IP-Identification.)
