[Pkg-utopia-maintainers] Bug#845520: network-manager randomising WiFi mac on device listed in /etc/network/interfaces

[Russell Stuart]

Package: network-manager
Version: 1.4.2-2
Severity: important

The first issue is listed in the subject: NetworkManager is randomising
the mac address of a WiFi interface listed in /etc/network/interfaces.
At least I think it's NetworkManager because if I run
"systemctl disable network-manager" it doesn't happen.  Note that while
mac address randomisation is only meant to be happening while searching
for an access point, in this case since NetworkManager isn't managing
the interface it is still have it's randomised value when the
connection is made.

I thought it might be because Debian is now renaming the interface from
wlan0 to wlp2s0 and there was a race condition (NetworkManager was
randomising while it was named wlan0), so I added wlan0 to
/etc/network/interfaces too, but it had no effect.

The second issue is to work around the problem for now I added
appropriate options to /etc/NetworkManager/NetworkManager.conf, but they
also had no effect(!)

Severity is important because I'm out of work arounds so I have to
disable network-manager entirely while at work - they like to know my
mac address.
