wpabuf overflow with WPS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I use trunk for board. I would like to add WPS to it. The Clearfog board is working as Access Point enabling WPA2-PSK and WPS Push Button. The hostapd is started from shell with -dd and the configuration file from https://wireless.wiki.kernel.org/en/users/drivers/ath10k/configuration . After the AP started, I enable the WPS by|
|

hostapd_cli wps_pbc

and also in my Nexus 9 tablet.

And the output show as

root@OpenWrt:~# hostapd -dd hostapd.cfg
Configuration file: hostapd.cfg

Any ideas about it ?
