Bug 107406 – BRIGDE net.module doesn't load/work !!!

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Sergey Anufrienko 2005-09-27 09:16:11 UTC]

The bridge module doesn't gets loaded on my system, altrough I have defined 
some bridges in /etc/conf.d/net. If I force loading of the module, the 
following error is displayed:

missing required function interface_down

How to fix this issue? Don't want to write custom up scripts for net.

Reproducible: Always
Steps to Reproduce:
1. just force the bridge mod to load (probably the bug is only on my OS and is 
here because an emerge --update didn't update a file?)
2.
3.

Actual Results:  
INIT: Entering runlevel: 3
 * Starting eth0
 *   WARNING: You are forcing modules!
 *   Do not complain or file bugs if things start breaking
 *       bridge: missing required function interface_down


Expected Results:  
Bring up the bridge :)

You're forcing modules - which is a big no-no with a big warning attached.

Stop forcing modules, ensure that bridging support is enabled in your kernel,
emerge bridge-utils and you should be good to go.

If that still fails, attach your conf.d/net file to this bug and re-open.

This is what i'm actually trying to get

This script works instead of the not-working net for now.

[Comment 4 Sergey Anufrienko 2005-10-06 21:59:32 UTC]

All the required packages & kernel bridge support is active, because
brctl actually exists and works, but not with the netscripts :)

As you asked, file attached. Reopening bug.

Try this configuration

Hmmmmm. This may only work with code I've just committed to our svn repo - you
may have to wait for baselayout-1.12.0_pre9.

Re-Open if so
