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.htmlhttps://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,

Add FTM range request via RRM. The AP sends Radio measurement request
with FTM range request as a request for the receiving STA to send FTM
requests to the given list of APs. The neighbor report part of the
request is taken from the neighbor database.
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
min_ap: Minimum AP Count (1..15); minimum number of requested FTM ranges
between the associated STA and the listed APs
responder: List of BSSIDs for neighboring APs for which a measurement
is requested

Add a configurable neighbor database that includes the content of
Nighbor Report element, LCI and Location Civic subelements and SSID.
All parameters for a neighbor must be updated at once; Neighbor Report
element and SSID are mandatory, LCI and civic are optional. The age of
LCI is set to the time of neighbor update.
The control interface API is:
SET_NEIGHBOR <BSSID> <ssid=SSID> <nr=data> [lci=<data>] [civic=<data>]
To delete a neighbor use:
REMOVE_NEIGHBOR <BSSID> <SSID>

This extends the wpa_supplicant PMKSA_FLUSH control interface command to

and mesh mode. In addition, this adds a hostapd PMKSA_FLUSH control
interface command to flush the PMKSA entries.

If the RADIUS server includes deauthentication request in Access-Accept,
send a WNM-Notification frame to the station after 4-way handshake and
disconnect the station after configurable timeout.
A new control interface command, WNM_DEAUTH_REQ, is added for testing
purposes to allow the notification frame to sent based on local request.
This case does not disconnect the station automatically, i.e., a
separate control interface command would be needed for that.
