Here's a PATCH v2 3/3 for this patchset.<br>
<br>
<a href="http://ix.io/7Bz" target="_blank">http://ix.io/7Bz</a><br>
<br>
Since other patches have been applied and I'm unable to post such a<br>
big patch to the mailing list server I'm simply replying to the cover<br>
letter.<br>
<br>
PATCH v2:<br>
* change message level of one wpa_printf<br>
* zero scan_cb pointer upon scan completion<br>
* update copyright notices (Jouni)<br>
<br>

Hello list,<br>
<br>
As of today, maybe for about 2 weeks, I've compiled "openssl(1.0.1)",<br>
"libnl(1.1.4)" and "hostapd(0.7.3)" on uClinux(2.6.27) with the modules<br>
below.<br>
<br>
rt2800usb.ko<br>
rt2800lib.ko<br>
rt2x00usb.ko<br>
rt2x00lib.ko<br>
mac80211.ko<br>
cfg80211.ko<br>
compat.ko<br>
compat_wireless.ko<br>
<br>
My device is RT5370.<br>
<br>
So, now I can find the SSID I wrote on the hostapd.conf.<br>
But I didn't succeed to connect to my device with my android phone.<br>
Authentication fails until now.<br>
<br>
Now I wonder what else do I need to do more?<br>
>From quick search there are "brctl", "iw", "iwconfig" and "dhcpd".<br>
These seems to be the items I must prepare.<br>
<br>
I need to make my device(RT5370) an AP. And with this AP I must be able to<br>
provide a WLAN network in an area.<br>
<br>
Do I need to prepare(cross build and install) "brctl" and "dhcpd" to do<br>
this?<br>
I believe iw and iwconfig are not the must items.<br>
<br>
>From the failure to connect to the device, I learned I need brctl.... I am<br>
not sure, though...<br>
<br>
Could you please guide me how to do and what to do now?<br>
<br>
Thank you very much in advance!<br>
<br>
Sincerely<br>
Journeyer<br>

<br>
First, thanks for the detailed HotSpot 2.0 readme.<br>
<br>
I do have a few questions after reading this.<br>
<br>
1) Is it ever valid to enable hs20 and NOT enable the 802.11u interworking?<br>
I think the answer is no, but I haven't seen any explicit answer in the docs.<br>
<br>
2) How complete is the current 802.11u & HS20 implementation in wpa_supplicant and<br>
hostapd? Any known limitations that still need some work?<br>
<br>
3) When I enabled 802.11u in hostapd, I see a brief mention that Interworking is enabled<br>
in the 'iw' scan results, but I do not see any details. Is that a limitation in 'iw'<br>
or would I need to somehow get that info from supplicant instead?<br>
<br>
Thanks,<br>
Ben<br>
