[Pkg-utopia-maintainers] Bug#819808: does not work with hidepid anymore

[Marc Dequènes (duck)]

Package: network-manager
Version: 1.1.92-1
Severity: important


Quack,

IIRC, around January, my nm-client stopped working. I was relocating so 
I don't know at which exact version things changed.

I found that mounting /proc with hidepid to 1 or 2 makes all nm clients 
unusable:
$ nmcli g
(process:6557): nmcli-CRITICAL **: Error: Could not create NMClient 
object: Unable to authenticate request..

Without changing session, remounting with hidepid to 0 instantly solves 
the problem:
$ nmcli g
STATE      CONNECTIVITY  WIFI-HW  WIFI     WWAN-HW  WWAN
connected  full          enabled  enabled  enabled  enabled

The version in stable (0.9.10.0-7) does not have this problem, so this 
is a regression.

This is a desired and planned (https://wiki.debian.org/Hardening/Goals) 
security feature so we should care about this.

Regards.
