Rich Felker	8c0c9c69a1	mq_notify: rework to fix use-after-close/double-close bugs in the error path where the mq_notify syscall fails, the initiating thread may have closed the socket before the worker thread calls recv on it. even in the absence of such a race, if the recv call failed, e.g. due to seccomp policy blocking it, the worker thread could proceed to close, producing a double-close condition. this can all be simplified by moving the mq_notify syscall into the new thread, so that the error case does not require pthread_cancel. now, the initiating thread only needs to read back the error status after waiting for the worker thread to consume its arguments.	3 years ago
