Bug 714168 – net-misc/networkmanager-1.26.2: udev rule for setting ENV{ID_NET_DRIVER} on devices is broken because of wrong hardcoded path for sed

• Status: CONFIRMED
• Product: Gentoo Linux

[Description Andrei Slavoiu 2020-03-24 13:26:43 UTC]

The rule in is:
ENV{ID_NET_DRIVER}=="veth", ENV{NM_UNMANAGED}="1"

however, on my system, no network device has ID_NET_DRIVER set so the rule is never matched.

The present attributes are:
P: /devices/virtual/net/vethcf09565
E: DEVPATH=/devices/virtual/net/vethcf09565
E: IFINDEX=10
E: INTERFACE=vethcf09565
E: SUBSYSTEM=net
E: USEC_INITIALIZED=6109932011
E: net.ifnames=0

Reproducible: Always

[Comment 2 Andrei Slavoiu 2020-03-24 13:31:39 UTC]

btw, as a workaround, I changed the rule to:
ENV{INTERFACE}=="veth*", ENV{NM_UNMANAGED}="1"

I wonder if not this file is the reason:
   /lib/udev/rules.d/84-nm-drivers.rules
it has /usr/sbin/ethtool hardcoded and Gentoo NM does not
depend on ethtool.

Your rule is better though as it does not depend on ethtool at all.

[Comment 4 Andrei Slavoiu 2020-03-30 15:43:07 UTC]

You are right, /lib/udev/rules.d/84-nm-drivers.rules is the broken one, but not necessarily because of ethtool hardcoded path, I do have it there. But on Gentoo "sed" is installed in /bin, not /usr/bin.

Right, I forgot it was sed, not ethtool.
Still good to loose the ethtool/sed dependency though

This needs upstreaming in a more complete form

[Comment 8 Matt Turner 2022-05-18 02:55:12 UTC]

In the v1.38.0 NEWS file I see

> * Veth devices with name "eth*" are now managed by default via the
>   udev rule. This is to support managing the network in LXD containers.

Does this resolve the issue?

[Comment 9 Stephen Bosch 2023-04-28 08:06:28 UTC]

What still needs to be done here?

How can I test if this is resolved? (I fixed the problem manually but don't recall how.)
