Fix a race condition that affects pfsync interface deletion. When a pfsync interface is being deleted, all its timeout handlers and pfsync_send_dispatch() have to stop accessing the software context before the context is freed. Ensure sufficient synchronization by acquiring NET_LOCK() and clearing `pfsyncif' inside the critical section in pfsync_clone_destroy(). When a timeout handler has entered the critical section, it has to check `pfsyncif' and bail out if the value is NULL. pfsync_send_dispatch() already does this check. Issue reported and fix tested by Hrvoje Popovski. OK mpi@ bluhm@ |
