But that really mostly means you don't care about the authenticated state at all, and there's no real associated state anyway ... > I would be okay with this approach.

Well, you'd have to do both, and we also can't break the userspace API now. > > This is a behaviour I introduced some time ago: > > > > 1153 sdata->u.ibss.control_port = params->control_port; > > > > which is set based on NL80211_ATTR_CONTROL_PORT and at the moment, > > in IBSS, I think it is only set by wpa_supplicant when using > > IBSS/RSN..you told me to use control_port instead of creating > > another member..but maybe it is general and could be used for > > something else?

Wouldn't completing the SAE handshake be sufficient information? johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
