[PATCH v3 mptcp-next 00/15] mptcp: refactor first subflow init

[Paolo Abeni <pabeni@redhat.com>]

This is the needed refactor for the selinux fixes, as discussed on
the ML.

Compared to v2 this revision introduces 2 additional patches:
1/15, just another cleanup found while addressing the recent bugs
12/15 factoring out a __inet_listener() helper, as suggested by Mat.

The only other patches with some change is 9/15, adding more
comments and consistently reporting the newly introduced error code
(a bit different from what discussed on the ML, for consistency's sake).

Paolo Abeni (15):
  mptcp: use mptcp_schedule_work() instead of open-codying it
  mptcp: fix locking for setsockopt corner-case
  mptcp: fix locking for in-kernel listener creation.
  mptcp: refactor passive socket initialization.
  mptcp: drop unneeded argument
  mptcp: drop legacy code.
  mptcp: avoid unneeded __mptcp_nmpc_socket() usage
  mptcp: move fastopen subflow check inside mptcp_sendmsg_fastopen()
  mptcp: move first subflow allocation at mpc access time
  mptcp: do not keep around the first subflow after disconnect.
  mptcp: fastclose msk when cleaning unaccepted sockets
  inet: factor out locked section of inet_accept() in a new helper
  mptcp: refactor mptcp_stream_accept()
  security, lsm: Introduce security_mptcp_add_subflow()
  selinux: Implement mptcp_add_subflow hook
