mptcp: fix shutdown vs fallback race
If the MPTCP socket shutdown happens before a fallback to TCP, and all the pending data have been already spooled, we never close the TCP connection. Address the issue explicitly checking for critical condition at fallback time. Fixes: 1e39e5a3 ("mptcp: infinite mapping sending") Fixes: 0348c690 ("mptcp: add the fallback check") Signed-off-by:Paolo Abeni <pabeni@redhat.com> Signed-off-by:
