Feature or enhancement

Proposal:

Linux recently added support to SO_PASSRIGHTS, to prevent unix sockets from receiving file descriptors.

Python should have this constant to be able to use it with setsockopt.

import socket
socket.SO_PASSRIGHTS

Has this already been discussed elsewhere?

Did you test your change? If yes, how?

Linux recently added support to SO_PASSRIGHTS

Recently means a few days ago: https://lwn.net/Articles/1023085/

The SO_PASSRIGHTS option found its way into the mainline kernel (as part of the large networking pull) on May 28 and will be available as of the 6.16 kernel release.

https://lwn.net/Articles/1023075/ says:

The 6.16 kernel now goes into the stabilization period, with the final release expected July 27 or August 3.
