Subject: [PATCHv3 net-next-2.6 0/5] XFRM,IPv6: Removal of RH2/HAO from IPsec-protected MIPv6 traffic

Hi,

This an updated version of the patches. For reference, introduction of
the feature is here http://thread.gmane.org/gmane.linux.network/172941

This version 3 now also builds with ipv6 modular. To do that, a helper
(input_addr_check()) has been added to struct xfrm_state_afinfo. To
avoid the penalty of xfrm_state_get/put_afinfo() calls from xfrm_input(),
I spent some time in the sources and came up with the idea of accessing
it safely as follows:

 x = xfrm_state_lookup(net, skb->mark, NULL, spi, nexthdr, family);
 if (x == NULL ||
     x->outer_mode->afinfo->input_addr_check(skb, x)) {
     ...

Tell me if I missed something.

Comments welcome.

Cheers,

a+
