[PATCH 2/3] wpa_supplicant: expose DPP config object PSK/PMK

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

 



From: Michal Kazior <michal@xxxxxxxxx>

Hostapd was already exposing this. There's no
reason not to expose it in wpa_supplicant.

This allows 3rd party apps interacting with the
control interface to handle DPP events to get
configs instead of needing to dance around with
update_config=1 and save_config.
