| |
| Authentication was added to the :mod:`multiprocessing` forkserver start |
| method control socket so that only processes with the authentication key |
| generated by the process that spawned the forkserver can control it. This |
| is an enhancement over the other :gh:`97514` fixes so that access is no |
| longer limited only by filesystem permissions. |
| |
| The file descriptor exchange of control pipes with the forked worker process |
| now requires an explicit acknowledgement byte to be sent over the socket |
| after the exchange on all forkserver supporting platforms. That makes |
| testing the above much easier. |
