====================
pull request (net): ipsec 2015-05-28

1) Fix a race in xfrm_state_lookup_byspi, we need to take
   the refcount before we release xfrm_state_lock.
   From Li RongQing.

2) Fix IV generation on ESN state. We used just the
   low order sequence numbers for IV generation on
   ESN, as a result the IV can repeat on the same
   state. Fix this by using the  high order sequence
   number bits too and make sure to always initialize
   the high order bits with zero. These patches are
   serious stable candidates. Fixes from Herbert Xu.

3) Fix the skb->mark handling on vti. We don't
   reset skb->mark in skb_scrub_packet anymore,
   so vti must care to restore the original
   value back after it was used to lookup the
   vti policy and state. Fixes from Alexander Duyck.

Please pull or let me know if there are problems.
