WPA authentication problem

[Robert Deliën]

Hi guys,

I'm using hostapd to setup an access point on a FreeScale i.MX28 processor with a ATH6KL SDIO based NIC.

With this setup, I can successfully connect to an existing access point, using both no security, WEP64/12 security and WPA/2 security. Setting up an access point with this test setup works if no security is used. However, when setting up an access point using WPA and/or WPA2, connections always fail.

I have maximized syslogging and a connection attempt from a client shows this in the log:
Mar 19 11:12:46 wivi daemon.info hostapd: wlan0: STA 10:fe:ed:58:21:06 IEEE 802.11: associated
Mar 19 11:12:46 wivi daemon.debug hostapd: wlan0: STA 10:fe:ed:58:21:06 WPA: event 1 notification

Mar 19 11:12:46 wivi daemon.debug hostapd: wlan0: STA 10:fe:ed:58:21:06 WPA: sending 3/4 msg of 4-Way Handshake
Mar 19 11:12:46 wivi daemon.info hostapd: wlan0: STA 10:fe:ed:58:21:06 IEEE 802.11: disassociated
Mar 19 11:12:46 wivi daemon.debug hostapd: wlan0: STA 10:fe:ed:58:21:06 WPA: event 2 notification
Mar 19 11:12:46 wivi daemon.debug hostapd: wlan0: STA 10:fe:ed:58:21:06 IEEE 802.1X: unauthorizing port

It seems like no second EAPOL-Key frame is received, or it's reception triggers a disassociation. Unfortunately no reason is logged.

I started with hostapd 2.3, but now I'm running 2.5-devel, straight from the trunk and the problem persists. I have tried different clients (Ubuntu 14.04, iOS) but the result is the same.

I couldn't find any similar problems on the web, so I'm probably overlooking something dead obvious. Can anybody point me in the right direction?

Cheers,

        Robert.
