wpasupplicant version 0.4.2 broken in breezy

[fimbulvetr]

I have a Dell Dimension D800 with a ipw2100 wireless card. I've been running hoary for months with no problems, along with wpa_supplicant shipped with hoary.
Upon an upgrade to breezy, wpa_supplicant stopped working, although everything else seems to work. Once manually installing the hoary deb, wpa would work again happily. Below is a paste of how wpa_supplicant would act when it was broken:

It repeats that over and over. A sudo dhclient eth1 never gets an address.

I also encountered this bug when upgrading from Hoary to Breezy. I was able to
work around it by downgrading to the Hoary version of wpasupplicant, and using
a 2.6.10 kernel. (The 2.6.12 kernels don't have madwifi support yet.)

I haven't determined for sure whether this is a Breezy bug or an upstream bug,
but since it seems like *all* of the wireless ioctls are failing, I'm leaning
toward some kind of build problem, which means it's a Breezy problem

[Reinhard Tartler (siretart)]

Err, I cannot confirm this. I'm using wpa_supplicant on breezy with current breezy kernel and madwifi very successfully, both with wpa (EAP-TLS) and plain web (this didn't work with hoary's wpasupplicant).

Perhaps I get next week a notebook with ipw2100 to test with breezy to check this.

[Mark Kohler (mkohler)]

Reinhard - What kernel are you using? My experience was that with Breezy's 2.6.12 kernels, my wireless interface was not detected by the kernel. Do you have madwifi working on one of Breezy's 2.6.12 kernels?

I'm using a Thinkpad R51 which has a built-in Atheros chipset.

[Mark Kohler (mkohler)]

Hmmm...I'm not sure what was happening before, but I now have WPA-PSK working on Breezy, with the 2.6.12.8-686 kernel, and the 0.4.2 wpasupplicant.

[Reinhard Tartler (siretart)]

siretart@hermes:/tmp
>> dpkg -s linux-image-$(uname -r) | grep Version
Version: 2.6.12-8.13

I'm just writing this mail via that kernel and madwifi chipset on my R40. I'm closing this bug now, Dan, if you are still experiencing this bug, please reopen it!

I can confirm that this problem has gone away. I am running:
