Subject: [PATCH net 0/2] mptcp: cope with syncookie on MP_JOINs

Currently syncookies on MP_JOIN connections are not handled correctly: the
connections fallback to TCP and are kept alive instead of resetting them at
fallback time.

The first patch propagates the required information up to syn_recv_sock time,
and the 2nd patch addresses the unifying the error path for all MP_JOIN
requests.

Paolo Abeni (2):
  mptcp: cache msk on MP_JOIN init_req
  mptcp: drop MP_JOIN request sock on syn cookies
