Bug Description
[Impact]
* A driver supports FT (IEEE 802.11r-2008 or fast BSS transition (FT),
also called fast roaming) if it either supports SME or the
NL80211_
wpa_supplicant currently doesn't take into account whether or not either
of those conditions are met. This can cause association failures, e.g.,
when an AP supports both WPA-EAP and FT-EAP but the driver doesn't
support FT (wpa_supplicant will decide to do FT-EAP since it is unaware
the driver doesn't support it).
* This is known to affect users at least users with popular chip-sets,
such as BCM20703A1 or BCM4350 (notably present in the popular XPS 13/15
laptops).
* The upload fixes the bug by allowing an FT suite to be selected only
when the driver also supports FT.
[Test Case]
* requires affected hardware and wpa_supplicant built with CONFIG_IEEE80211R
and connecting to an AP supporting WPA-EAP and FT-EAP
[Regression Potential]
* a driver not advertising correctly its support for SME or the
NL80211_
using FT but would still be able to connect to APs
