tunnels: harmonize cleanup done on skb on xmit path

2013-09-04T04:27:25Z

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 Signed-off-by: David S. Miller

ipip: add x-netns support

2013-08-15T08:00:20Z

This patch allows to switch the netns when packet is encapsulated or decapsulated. In other word, the encapsulated packet is received in a netns, where the lookup is done to find the tunnel. Once the tunnel is found, the packet is decapsulated and injecting into the corresponding interface which stands to another netns. When one of the two netns is removed, the tunnel is destroyed.

ip_tunnel: Do not use inner ip-header-id for tunnel ip-header-id.

2013-08-13T23:52:50Z

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.) CC: Jarno Rajahalme CC: Ansis Atteka Signed-off-by: Pravin B Shelar Signed-off-by: David S. Miller

ip_tunnel: embed hash list head

2013-08-07T23:47:52Z

The IP tunnel hash heads can be embedded in the per-net structure since it is a fixed size. Reduce the size so that the total structure fits in a page size. The original size was overly large, even NETDEV_HASHBITS is only 8 bits! Also, add some white space for readability. Signed-off-by: Stephen Hemminger Acked-by: Pravin B Shelar .

ip_tunnel: Protect tunnel functions with CONFIG_INET guard.

2013-06-24T07:18:38Z

Tunnel constants can be used in generic code but in these cases the inline functions in ip_tunnels.h cause compilation problems if CONFIG_INET is not set. CC: Pravin Shelar Reported-by: Randy Dunlap Signed-off-by: Jesse Gross Acked-by: Randy Dunlap Signed-off-by: David S. Miller

ip_tunnel: Add dont fragment flag.

2013-06-20T01:07:41Z

This flag will be used by ovs tunneling. Signed-off-by: Pravin B Shelar Signed-off-by: David S. Miller

ip_tunnel: push generic protocol handling to ip_tunnel module.

2013-06-20T01:07:41Z

Process skb tunnel header before sending packet to protocol handler. this allows code sharing between gre and ovs gre modules. Signed-off-by: Pravin B Shelar Signed-off-by: David S. Miller
