[PATCH mptcp-net v5 0/2] mptcp: fix another close hang-up

[Paolo Abeni <pabeni@redhat.com>]

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.

v4 -> v5:
 - let the tout always expire for dead socks (Mat)
 - fix comment type (Mat)
 - targeting net, added fixes tag

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: fix dangling connection hang-up
