Subject: [PATCH net-next v2 0/5] udp_tunnel: GRO optimization follow-up

Syzkaller and Nathan reported a few issues on the reference changeset.
This series tries to address them all and additionally does some little
cleanup.

See the individual patches for the details.

Should this prove to be too invasive, too late or ineffective, I'll be
ok with a revert before the upcoming net-next PR.

Paolo Abeni (5):
  udp_tunnel: properly deal with xfrm gro encap.
  udp_tunnel: fix compile warning
  udp_tunnel: fix UaF in GRO accounting
  udp_tunnel: avoid inconsistent local variables usage
  udp_tunnel: prevent GRO lookup optimization for user-space sockets
