====================
pull request (net): ipsec 2017-08-21

1) Fix memleaks when ESP takes an error path.

2) Fix null pointer dereference when creating a sub policy
   that matches the same outer flow as main policy does.
   From Koichiro Den.

3) Fix possible out-of-bound access in xfrm_migrate.
   This patch should go to the stable trees too.
   From Vladis Dronov.

4) ESP can return positive and negative error values,
   so treat both cases as an error.

Please pull or let me know if there are problems.
