802.11r and L3
Mon Sep 28 00:46:00 PDT 2015
I'm implementing FT protocol, partly using the hostapd code. I have
already implemented the over-the-air scheme without resource request
protocol and it works well with mac80211_hwsim, two access points and
wpa_supplicant. Data frame (dhcp traffic) passed well after FT
authentication and association via simulated by mac80211_hwsim virtual
wireless interface of wpa_supplicant. But I have a problems with real
devices (Iphone 5 and Samsung Galaxy S5 mini on Android 4.4). After
successful roaming they resets their L3 data (IP address, gateway,
e.t.c.) and do not sends dhcp requests.
I have no idea why this is happens. Maybe I'm doing something wrong
while adding station to driver, but why mac802211_hwsim works then? Or I
have to send some additional information to client about L3 which I
overlook in standard and hostapd code?
