Hi Jouni,

For 802.11R, We are referring to the setup mentioned by 'Carlos Fernández' can be
accessed with following link
http://lists.shmoo.com/pipermail/hostap/2011-March/022860.html .

In our setup, using latest hostapd and wpa_supplicant, with following as the top
commit,

we are seeing that 2nd 'ft_ds' is failing consistently.

We have captured the steps and screen log at http://ix.io/6Cf . We can share the
supplicant and hostapd logs of the same if some one needs to look at.


For the first run, we get

>> ft_ds 02:00:00:00:01:00
>OK
>Trying to associate with 02:00:00:00:01:00 (SSID='ft-psk' freq=2417 MHz)

>CTRL-EVENT-CONNECTED - Connection to 02:00:00:00:01:00 completed [id=0 id_str=]

Notice the 'do not start 4-way handshake' which means it was successful FT-DS.


But for 2nd ft_ds we get following
>> ft_ds 02:00:00:00:00:00
>OK
>Trying to associate with 02:00:00:00:00:00 (SSID='ft-psk' freq=2412 MHz)
>SME: Association request to the driver failed
>CTRL-EVENT-SCAN-RESULTS


Are you aware of any such issue?
Or
Let us know if we are missing something obvious.


Thanks
