Is WPS supported on Linux systems using the wext driver?

[Charles Gordon]

Hi,

I'm trying to find out if wpa_supplicant can support WPS on an
embedded Linux system.  I built it with "CONFIG_WPS=y" in the .config
file and tried running it with this configuration file:

ctrl_interface=/var/run/wpa_supplicant
update_config=1

## -- Example MANAGED network
network={
	proto=WPS
	eap=WPS
}

I tried both the 6.10 and 7.3 versions.  However, when I run it I get
these errors:

Initializing interface 'wlan0' conf '/etc/wpa_supplicant.conf' driver
'wext' ctrl_interface 'N/A'
Configuration file '/etc/wpa_supplicant.conf' -> '/etc/wpa_supplicant.conf'

You may need to add support for this EAP method during wpa_supplicant
build time configuration.
See README for more information.

The documentation isn't clear (to me) about whether WPS is supported
by wpa_supplicant, and looking at the code it appears that it is only
supported by the NDIS driver.

Is there a way to support WPS with the standard WEXT driver?

Thanks for your help.
