AW: probe request / response wpa_supplicant

[volker.obhof.w at sew-eurodrive.de]

Hi,

I think I asked the wrong think. I don?t really want to parse a probe response. But the driver or kernel have to parse it and save the parsed data in a special struct that I can use the information in wpa_supplicant to do further steps. But I can?t find the function where the data of extra element IDs (IEs) is saved in wpa_supplicant after receiving probe response.

Thanks for your help.

Hi,

It really depends on what you want to do. You can modify the wpa_supplicant code, to request the kernel to pass probe responses to wpa_supplicant and also parse them in wpa_supplicant. For example see nl80211_register_frame() etc.

Regards,

Ilan.

Hi,

Are you asking about station scanning? These are usually done in kernel or the device (depends on the device and its capabilities). Have a look at cfg80211/mac80211 in the kernel to start with.

Regards,

Ilan.

Which function sends a probe request from STA to AP and handles a probe response from AP to STA?

I searched the code, set break points but I didn?t find it.

There is no function called like ?handle_probe_resp? or ?gen_probe_req?. How are called these function because I want to extend the parsing for probe response on wpa_supplicant.
