RFC 8684 appendix B describes how to use TCP Fast Open with MPTCP. This
series allows TFO use with MPTCP using the TCP_FASTOPEN_CONNECT socket
option. The scope here is limited to the initiator of the connection -
support for MSG_FASTOPEN and the listener side of the connection will be
in a separate series. The preexisting TCP fastopen code does most of the
work, so these changes mostly involve plumbing MPTCP through to those
TCP functions.

Patch 1 changes the MPTCP socket option code to pass the
TCP_FASTOPEN_CONNECT option through to the initial unconnected subflow.

Patch 2 exports the existing tcp_sendmsg_fastopen() function from tcp.c

Patch 3 adds the call to tcp_sendmsg_fastopen() from the MPTCP send
function.

Patch 4 modifies mptcp_poll() to handle the deferred TFO connection.


Benjamin Hesmans (3):
  mptcp: add TCP_FASTOPEN_CONNECT socket option
  tcp: export tcp_sendmsg_fastopen
  mptcp: poll allow write call before actual connect

Dmytro Shytyi (1):
  mptcp: handle defer connect in mptcp_sendmsg
