[PATCH mptcp-next v4 0/2] mptcp: fix another close hang-up

Posted by Paolo Abeni 8 months ago

If the TCP subflows close silently due to timeouts, the msk socket
can hang-up indefinitely.

Implement an additional close timeout triggered with the last subflow
close event and move the msk to TCP_CLOSE when it fires.

Should address issues/430 and issues/431.

v3 -> v4:
 - fix off-by-one in timer update/check (sigh, trival math is too
   hard:/)

v2 -> v3:
 - fix int overlflow in patch 2/2

v1 -> v2:
 - fix timeout timer scheduling in patch 2/2 (timeout never fired on v1)

Paolo Abeni (2):
  mptcp: rename timer related helper to less confusing names
  mptcp: implement connection level timeout.
