====================
pull request (net): ipsec 2019-02-21

1) Don't do TX bytes accounting for the esp trailer when sending
   from a request socket as this will result in an out of bounds
   memory write. From Martin Willi.

2) Destroy xfrm_state synchronously on net exit path to
   avoid nested gc flush callbacks that may trigger a
   warning in xfrm6_tunnel_net_exit(). From Cong Wang.

3) Do an unconditionally clone in pfkey_broadcast_one()
   to avoid a race when freeing the skb.
   From Sean Tranchetti.

4) Fix inbound traffic via XFRM interfaces across network
   namespaces. We did the lookup for interfaces and policies
   in the wrong namespace. From Tobias Brunner.

Please pull or let me know if there are problems.
