85bab32522 hostapd_cli: Process events received following control iface commands
Events received as an immediate result of control interface commands
end up on the control request message callback function instead of
the registered read socket. This makes for example the station list
used for complete functions for disassociate and deauthenticate out
of sync. Process events in the message callback function too to ensure
no events are missed.

33111c910b Check for NULL qsort() base pointers
There are a couple of places in wpa_supplicant/hostapd where qsort() can
be called with a NULL base pointer. This results in undefined behavior
according to the C standard and with some standard C libraries (ARM RVCT
2.2) results in a data abort/memory exception. Fix this by skipping such
calls since there is nothing needing to be sorted.

3b5b7aa8fb FILS: Use AEAD cipher to check received EAPOL-Key frames (AP)
This changes 4-way handshake authenticator processing to decrypt the
EAPOL-Key frames using an AEAD cipher (AES-SIV with FILS AKMs) before
processing the Key Data field. This replaces Key MIC validation for the
cases where AEAD cipher is used. This needs to move the EAPOL-Key msg
2/4 RSN element processing to happen only after the PTK has been derived
and validated. That is done for all AKMs to avoid extra complexity with
having to maintain two code paths for this.

96590564d6 FT: Allow PMK-R0 and PMK-R1 for FT-PSK to be generated locally
Station should be able to connect initially without ft_pmk_cache filled,
so the target AP has the PSK available and thus the same information as
the origin AP. Therefore neither caching nor communication between the
APs with respect to PMK-R0 or PMK-R1 or VLANs is required if the target
AP derives the required PMKs locally.

This patch introduces the generation of the required PMKs locally for
FT-PSK. Additionally, PMK-R0 is not stored (and thus pushed) for FT-PSK.

So for FT-PSK networks, no configuration of inter-AP communication is
needed anymore when using ft_psk_generate_local=1 configuration. The
default behavior (ft_psk_generate_local=0) remains to use the pull/push
protocol.

04059ab844 Passive Client Taxonomy
Implement the signature mechanism described in the paper
"Passive Taxonomy of Wifi Clients using MLME Frame Contents"
published by Denton Gentry and Avery Pennarun.

http://research.google.com/pubs/pub45429.html
https://arxiv.org/abs/1608.01725

This involves:
1. Add a CONFIG_TAXONOMY compile option. Enabling taxonomy incurs
   a memory overhead of up to several kilobytes per associated
   station.
2. If enabled, store the Probe Request and (Re)Associate Request frame in
   struct sta_info.
3. Implement code to extract the ID of each Information Element,
   plus selected fields and bitmasks from certain IEs, into a
   descriptive text string. This is done in a new source file,
   src/ap/taxonomy.c.
4. Implement a "signature qq:rr:ss:tt:uu:vv" command
   in hostapd_cli to retrieve the signature.

Signatures take the form of a text string. For example, a signature
for the Nexus 5X is:
  wifi4|probe:0,1,127,45,191,htcap:01ef,htagg:03,htmcs:0000ffff,vhtcap:338061b2,
  vhtrxmcs:030cfffa,vhttxmcs:030cfffa,extcap:00000a0201000040|assoc:0,1,48,45,
  221(0050f2,2),191,127,htcap:01ef,htagg:03,htmcs:0000ffff,vhtcap:339071b2,

faecb39236 hostapd: Allow FTM functionality to be published
Add configuration options that control publishing of fine timing
measurement (FTM) responder and initiator functionality via bits 70, 71
of Extended Capabilities element. Typically, FTM functionality is
controlled by a location framework outside hostapd. When framework is
activated, it will use hostapd to configure the AP to publish the FTM
functionality. See IEEE P802.11-REVmc/D7.0, 9.4.2.27.

fc72a48a63 hostapd: Use stations nsts capability in (Re)Association Response frame
Some deployed stations incorrectly consider nsts capability in
(Re)Association Response frame as required capability instead of maximum
capability and if it is greater than station's capability then beamform
will not happen in uplink traffic.

This commit adds support for an optional workaround to use station's
nsts capability in (Re)Association Response frame if the station's nsts
is less than AP by using the use_sta_nsts=1 configuration parameter.
This configuration is introduced in this commit and it is disabled by
default.

with FTM range request as a request for the receiving STA to send FTM

The control interface command is:

REQ_RANGE <dst addr> <rand_int> <min_ap> <responder> [<responder>..]

dst addr: MAC address of an associated STA
rand_int: Randomization Interval (0..65535) in TUs
