Number of regressions had shown up in wpa_supplicant implementation of
SAE group selection due to different integer array termination (-1 in
hostapd, 0 in wpa_supplicant) being used for SAE groups. The
default_groups list did not seem to use any explicit termination value.
In addition, the sae_group_index was not cleared back to 0 properly
whenever a new SAE session was started.

The Hotspot 2.0 specification seems to mandate this element to be
included in all (Re)Association Request frames if the station is Hotspot
2.0 capable. However, that results in conflicts with other requirements
like no TKIP use when this element is present. The design is really
supposed to include the indication element only for Hotspot 2.0
associations regardless of what the current specification implies.
Remove the HS 2.0 Indication element from (Re)Association Request frame
whenever the connection is not for Hotspot 2.0 purposes.

The unprotected disconnection events were previously processed only for
drivers that used the wpa_supplicant SME implementation (separate
authentication and association commands). However, this can be useful
for drivers that use the connect API, so remove the limitation and allow
the same IEEE 802.11w SA Query mechanism to be used even without full
use of the wpa_supplicant SME.

hostapd can now be configured to use anti-clogging mechanism based on
the new sae_anti_clogging_threshold parameter (which is
dot11RSNASAEAntiCloggingThreshold in the standard). The token is

This introduces new AKM for SAE and FT-SAE and adds the initial parts
for going through the SAE Authentication frame exchange. The actual SAE
algorithm and new fields in Authentication frames are not yet included
in this commit and will be added separately. This version is able to
complete a dummy authentication with the correct authentication
algorithm and transaction values to allow cfg80211/mac80211 drivers to
be tested (all the missing parts can be handled with
hostapd/wpa_supplicant changes).

If key_mgmt was set to allow both WPA and non-WPA IEEE 802.1X (i.e., to
IEEE8021X WPA-EAP), non-WPA IEEE 802.1X was rejected while preparing
association parameters. Allow this special case to be handled by
selecting non-WPA case if the scan results for the AP do not include
either WPA or RSN elements.

Some of the authentication/association failure paths left wpa_state to
its previous value. This can result in unexpected behavior when
wpa_supplicant tries to find an AP to connect to since the uncleared
state can result the in the selected BSS being ignored if it is same as
the previously used BSS. This could happen, e.g., when wpa_supplicant
SME was used and the AP rejected authentication. Fix this by explicitly
setting state to DISCONNECTED on auth/assoc failures that did not yet do
this.

Add support for HT STA to report 40 MHz intolerance to the associated AP.
A HT station generates a report (20/40 BSS coexistence) of channel list
if it finds a non-HT capable AP or a HT AP which prohibits 40 MHz
transmission (i.e., 40 MHz intolerant bit is set in HT capabilities IE)
from the scan results.
Parse the OBSS scan parameter from Beacon or Probe Response frames and
schedule periodic scan to generate 20/40 coexistence channel report if
requested to do so. This patch decodes Scan Interval alone from the OBSS
Scan Parameters element and triggers scan on timeout.

MCS Rates can be disabled to force to slower speeds when using HT.
Rates cannot be forced higher.

A-MPDU Factor and A-MPDU Density can be modified.
Please note that these are suggestions to the kernel. Only mac80211

This code was used only with driver_test.c to allow MLME operations
in hostapd to be tested without having to use a real radio. There
are no plans on extending this to any other use than testing and
mac80211_hwsim has now obsoled the need for this type of testing.
As such, we can drop this code from wpa_supplicant to clean up the
implementation of unnecessary complexity.
This patch uses sched_scan, if available, when the driver is
initialized. It also adds a couple of cancel operations where
appropriate.

The previous code was trying to figure out which WPA version is
used based on the extra IEs requested for Association Request. That
did not work properly in cases where non-WPA networks are used with
some extra IEs. Fix this by using more robust mechanism for passing
the WPA versions from core wpa_supplicant to the driver_ops
associate().
Fix the previous code that was hardcoding the p2p parameter based
on the driver P2P capability regardless of whether the connection
was really used for P2P or not.
