These patches address two issues in MPTCP.

Patch 1 fixes a locking issue affecting MPTCP-level retransmissions.

Patches 2-4 improve handling of out-of-order packet arrival early in a
connection, so it falls back to TCP rather than forcing a
reset. Includes a selftest.

Paolo Abeni (4):
  mptcp: fix sk_forward_memory corruption on retransmission
  mptcp: always parse mptcp options for MPC reqsk
  mptcp: do not reset MP_CAPABLE subflow on mapping errors
  mptcp: update selftest for fallback due to OoO
