Red Hat Bugzilla – Bug 213200
kudzu does not detect VAPs used in the madwifi subsystem
Last modified: 2014-03-16 23:03:38 EDT
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?
kudzu is deprecated in any case - apps that need to enumerate network devices
should be using HAL.
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.
s-c-network uses kudzu ATM. It does need to be ported eventually.
Which devices are the configurable ones?
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.
