[PATCH net-next 0/8] mptcp: MSG_FASTOPEN and TFO listener side support
Posted by Matthieu Baerts 1 year, 4 months ago
Before this series, only the initiator of a connection was able to combine both
TCP FastOpen and MPTCP when using TCP_FASTOPEN_CONNECT socket option.

These new patches here add (in theory) the full support of TFO with MPTCP, which
means:

 - MSG_FASTOPEN sendmsg flag support (patch 1/8)
 - TFO support for the listener side (patches 2-5/8)
 - TCP_FASTOPEN socket option (patch 6/8)
 - TCP_FASTOPEN_KEY socket option (patch 7/8)

To support TFO for the server side, a few preparation patches are needed
(patches 2 to 5/8). Some of them were inspired by a previous work from Benjamin
Hesmans.

Note that TFO support with MPTCP has been validated with selftests (patch 8/8)
but also with Packetdrill tests running with a modified but still very WIP
version supporting MPTCP. Both the modified tool and the tests are available
online:

Dmytro Shytyi (5):
  mptcp: add MSG_FASTOPEN sendmsg flag support
  mptcp: implement delayed seq generation for passive fastopen
  mptcp: add subflow_v(4,6)_send_synack()
  mptcp: add TCP_FASTOPEN sock option
  selftests: mptcp: mptfo Initiator/Listener

Matthieu Baerts (1):
  mptcp: add support for TCP_FASTOPEN_KEY sockopt

Paolo Abeni (2):
  mptcp: track accurately the incoming MPC suboption type
  mptcp: consolidate initial ack seq generation
