13870d5d7b
caused by use of an invalid kgss_gssd_handle during an upcall to the gssd daemon when it has exited. This patch seems to avoid the crashes by holding a reference count on the kgss_gssd_handle until the upcall is done. It also adds a new mutex kgss_gssd_lock used to make manipulation of kgss_gssd_handle SMP safe. Tested by: Illias A. Marinos, Herbert Poeckl Reviewed by: jhb MFC after: 2 weeks
