[NETFILTER]: Fix xfrm lookup in ip_route_me_harder/ip6_route_me_harder
ip_route_me_harder doesn't use the port numbers of the xfrm lookup and uses ip_route_input for non-local addresses which doesn't do a xfrm lookup, ip6_route_me_harder doesn't do a xfrm lookup at all. Use xfrm_decode_session and do the lookup manually, make sure both only do the lookup if the packet hasn't been transformed already. Makeing sure the lookup only happens once needs a new field in the IP6CB, which exceeds the size of skb->cb. The size of skb->cb is increased to 48b. Apparently the IPv6 mobile extensions need some more room anyway. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
