If a client disconnected all its interfaces and reconnects when
the come back, it will likely start from any ip address returned
dns, which means it can try to connect to a different ctdb node.
The old node may not have noticed the disconnect and still holds
the client_guid based smbd.
Up unil now the new node returned NT_STATUS_NOT_SUPPORTED to
the SMB2 Negotiate request, as messaging_send_iov[_from]() will
return -1/ENOSYS if a file descriptor os passed to a process on
a different node.
Now we tell the other node to teardown all client connections
belonging to the client-guid.
Note that this is not authenticated, but if an attacker can
capture the client-guid, he can also inject TCP resets anyway,
to get the same effect.
