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. ==================== Link: https://lore.kernel.org/r/20220926232739.76317-1-mathew.j.martineau@linux.intel.com Signed-off-by: Jakub Kicinski --- 30b172ee56658b9c297c6d73f0a5c32ed1470dd0
