====================
pull request (net): ipsec 2018-07-27

1) Fix PMTU handling of vti6. We update the PMTU on
   the xfrm dst_entry which is not cached anymore
   after the flowchache removal. So update the
   PMTU of the original dst_entry instead.
   From Eyal Birger.

2) Fix a leak of kernel memory to userspace.
   From Eric Dumazet.

3) Fix a possible dst_entry memleak in xfrm_lookup_route.
   From Tommi Rantala.

4) Fix a skb leak in case we can't call nlmsg_multicast
   from xfrm_nlmsg_multicast. From Florian Westphal.

5) Fix a leak of a temporary buffer in the error path of
   esp6_input. From Zhen Lei.
