[REGRESSION] af_unix: Introduce SO_PASSRIGHTS - break OpenGL

["Jacek Łuczak" <difrost.kernel@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 376 bytes --]

Hi,

on 6.16-rc1 Hyprland (WM) crashes on start (more details in amdgpu issue 
tracker where I've originally reported that issue: 
https://gitlab.freedesktop.org/drm/amd/-/issues/4306). Bisection points 
to: [3f84d577b79d2fce8221244f2509734940609ca6] af_unix: Inherit sk_flags 
at connect(). -- log attached.

Reverting entire SO_PASSRIGHTS fixes the issue.

Regards,

-Jacek
