Subject: [PATCH net-next 0/4] mptcp: Fastclose edge cases and error handling

MPTCP has existing code to use the MP_FASTCLOSE option header, which
works like a RST for the MPTCP-level connection (regular RSTs only
affect specific subflows in MPTCP). This series has some improvements
for fastclose.

Patch 1 aligns fastclose socket error handling with TCP RST behavior on
TCP sockets.

Patch 2 adds use of MP_FASTCLOSE in some more edge cases, like file
descriptor close, FIN_WAIT timeout, and when the socket has unread data.

Patch 3 updates the fastclose self tests.

Patch 4 does not change any code, just fixes some outdated comments.

Paolo Abeni (4):
  mptcp: propagate fastclose error
  mptcp: use fastclose on more edge scenarios
  selftests: mptcp: update and extend fastclose test-cases
  mptcp: update misleading comments.
