Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says:
====================
pull request (net-next): ipsec-next 2014-12-03
1) Fix a set but not used warning. From Fabian Frederick.
2) Currently we make sequence number values available to userspace
only if we use ESN. Make the sequence number values also available
for non ESN states. From Zhi Ding.
3) Remove socket policy hashing. We don't need it because socket
policies are always looked up via a linked list. From Herbert Xu.
4) After removing socket policy hashing, we can use __xfrm_policy_link
in xfrm_policy_insert. From Herbert Xu.
5) Add a lookup method for vti6 tunnels with wildcard endpoints.
I forgot this when I initially implemented vti6.
Please pull or let me know if there are problems.
