2014-03-14xfrm: Introduce xfrm_input_afinfo to access the the callbacks properlySteffen Klassert
IPv6 can be build as a module, so we need mechanism to access the address family dependent callback functions properly. Therefore we introduce xfrm_input_afinfo, similar to that what we have for the address family dependent part of policies and states. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
2014-02-25xfrm: Add xfrm_tunnel_skb_cb to the skb common bufferSteffen Klassert
IPsec vti_rcv needs to remind the tunnel pointer to check it later at the vti_rcv_cb callback. So add this pointer to the IPsec common buffer, initialize it and check it to avoid transport state matching of a tunneled packet. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
