MPTCP's DATA_FIN flag is sent in a DSS option when closing the
MPTCP-level connection. This patch series prepares for correct DATA_FIN
handling across multiple subflows (where individual subflows may
disconnect without closing the entire MPTCP connection) by changing the
way the MPTCP-level socket requests a DATA_FIN on a subflow and
propagates the necessary data for the TCP option.


Mat Martineau (3):
  mptcp: Check connection state before attempting send
  mptcp: Use per-subflow storage for DATA_FIN sequence number
  mptcp: Only send DATA_FIN with final mapping
