Description Richi Plana 2006-10-31 05:53:08 UTC
Description of problem:
The madwifi Atheros driver creates a physical interface port (wifi0) and one or
more Virtual Access Points (VAPs) that are the virtual devices that need to be
configured. kudzu only detects the physical port and so, first, does not detect
that the interface actually possesses wireless extensions, and second, does not
detect the actual interface that is configurable (via iwconfig and ifconfig).

I tested madwifi drivers from both the livna repository as well as the ATrpms
one. I understand freshrpms also has madwifi packages.

I am not certain which subsystem should change or even if a workaround should
just be used. Is there a way to tell kudzu about these virtual devices?

Comment 1 Bill Nottingham 2006-10-31 15:37:05 UTC
kudzu is deprecated in any case - apps that need to enumerate network devices
should be using HAL.

Comment 2 Richi Plana 2006-10-31 16:25:50 UTC
So what's the right solution for getting VAPs recognized why system-config-network?

As a side note, I did manage to track down another bug
(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187640) which mentions the
problem might be elsewhere. In that bug (possibly erroneously labeled a
system-config-network bug instead of a module-init-tools one), aliases aren't
recognized in module configurations located in /etc/modprobe.d/*. Adding a
"alias ath0 ath_pci" magically makes system-config-network aware of the device.

Is system-config-network using HAL, then? Will it be transitioned? Will it be
deprecated for NetworkManager?

Please re-prioritize this bug if it doesn't need fixing or tracking.

Comment 3 Bill Nottingham 2006-10-31 16:29:28 UTC
s-c-network uses kudzu ATM. It does need to be ported eventually.

Which devices are the configurable ones?

Comment 4 Richi Plana 2006-10-31 17:04:48 UTC
By convention, the ath* virtual devices are the configurable ones (with proper
wireless extensions). They're somewhat detected when an alias (such as "alias
ath0 ath_pci") is placed in /etc/modprobe.conf (but not in
/etc/modprobe.d/madwifi). I say somewhat because the "Description" for the
interface in s-c-network is just "ath_pci" instead of the proper "Atheros
Communciations..." as shown in the physical wifi0 device.

make sure no important bugs slip through the cracks.

If you're currently running a version of Fedora Core between 1 and 6,
please note that Fedora no longer maintains these releases. We strongly
encourage you to upgrade to a current Fedora release. In order to
refocus our efforts as a project we are flagging all of the open bugs
for releases which are no longer maintained and closing them.

If this bug is still open against Fedora Core 1 through 6, thirty days
from now, it will be closed 'WONTFIX'. If you can reporduce this bug in
the latest Fedora version, please change to the respective version. If

Comment 6 Bug Zapper 2008-05-06 16:38:20 UTC
This bug is open for a Fedora version that is no longer maintained and
will not be fixed by Fedora. Therefore we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen thus bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
