Subject: [PATCH net-next 0/4] mptcp: Miscellaneous fixes and a new test case

Patches 1 and 3 remove helpers that were iterating over the subflow
connection list without proper locking. Iteration was not needed in
either case.

Patch 2 fixes handling of MP_FAIL timeout, checking for orphaned
subflows instead of using the MPTCP socket data lock and connection
state.

Patch 4 adds a test for MP_FAIL timeout using tc pedit to induce checksum
failures.

Geliang Tang (1):
  selftests: mptcp: add MP_FAIL reset testcase

Mat Martineau (2):
  mptcp: Check for orphaned subflow before handling MP_FAIL timer
  mptcp: Do not traverse the subflow connection list without lock

Paolo Abeni (1):
  mptcp: stop using the mptcp_has_another_subflow() helper
