====================
pull request (net): ipsec 2018-05-31

1) Avoid possible overflow of the offset variable
   in  _decode_session6(), this fixes an infinite
   lookp there. From Eric Dumazet.

2) We may use an error pointer in the error path of
   xfrm_bundle_create(). Fix this by returning this
   pointer directly to the caller.

Please pull or let me know if there are problems.
