Example to configure a tunnel: modprobe sit ip netns add netns1 ip link add sit1 type sit remote 10.16.0.121 local 10.16.0.249 ip l s sit1 netns netns1 ip netns exec netns1 ip l s lo up ip netns exec netns1 ip l s sit1 up ip netns exec netns1 ip a a dev sit1 192.168.2.123 remote 192.168.2.121 ip netns exec netns1 ip -6 a a dev sit1 2001:1234::123 remote 2001:1234::121 Once this serie is approved, I will add the same feature for the module ipip and ip6_tunnel. v3: put again the test about netns before calling skb_scrub_packet() add a missing skb_scrub_packet() call in ip_tunnel_xmit() v2: rename dev_cleanup_skb to skb_scrub_packet move skb_scrub_packet to skbuff.c fix netns cleanup remove string comparison in netns cleanup add a comment about FB device call skb_scrub_packet() unconditionnaly remove 'RFC' include/linux/skbuff.h | 1 + include/net/ip_tunnels.h | 1 + net/core/dev.c | 11 +---------- net/core/skbuff.c | 23 +++++++++++++++++++++++ net/ipv4/ip_tunnel.c | 10 +++++++++- net/ipv6/sit.c | 42 ++++++++++++++++++++++++++++++++---------- 6 files changed, 67 insertions(+), 21 deletions(-) Comments are welcome.
