[maemo-developers] wpa_supplicant and cx3110x

[From: Andrew Barr]

Hello,

I am using an N800 running Angstrom[0] booting off of an SD card, using
an initfs modified to multiboot as is documented on the wiki[1]. I am
having some trouble getting wpa_supplicant to authenticate on my WPA-EAP
(PEAP-MSCHAPv2/TKIP) home network. This works fine in the Internet
Tablet OS provided power management is turned off (something is
apparently wrong with 802.11 PSM on my AP). It appears to be off by
default when the tablet is booted into Angstrom
(/sys/devices/platform/wlan-omap/psm is '0'). The EAP auth seems to work
ok (eap_state in 'wpa_cli stat' is SUCCESS) but the crypto gets hung up
at 4WAY_HANDSHAKE and times out. I have observed this on my own home
network and at least one other similar network at my school. I am using
wpa_supplicant 0.6.3 linked with openssl (also tested 0.5.5 linked with
gnutls) and the 'wext' driver. The cx3110x driver is the one shipped in
the initfs for the latest official Nokia firmware. 

I can provide packet captures and similar debugging info, perhaps the
maintainer of the driver can help me out with this? The last message I
saw concerning this was from late 2007, talking about running
wpa_supplicant under ITOS and this was not yet supported as cx3110x did
not yet support WE-18 or later. This appears to no longer be the case,
as /proc/net/wireless indicates WE-22 and no version mismatch messages
are printed by iwconfig. Also, the output of 'iwlist wlan0 scan' has WPA
info, which indicates to me that WPA via Wireless Extensions _should_
work.

Thanks for any help.
