78a37200f8 tests: Reset wlan5 device before RELOG command
This moves the wpa_supplicant debug entries from the end of a test case
using a dynamically added wlan5 interface to the correct test case,
i.e., the test case that added the interface instead of whatever test
case happens to follow this.

14220fe64c Flush the BSS (scan) entries when an interface becomes disabled
When an interface becomes disabled (e.g., when RF-kill becomes blocked)
we should clear the stored scan results to avoid maintaining stale

Fix this by flushing the BSS entries when an interface becomes

442819406c taxonomy: Store Probe Request frames in hostapd_sta_info
A weakness in the initial client taxonomy mechanism is from storing both
the Probe and Associate in struct sta_info. struct sta_info is created
after a client associates (or starts authentication frame exchange),
which means that any Probe Request frames sent prior to association are
not retained. The Associate Request frame has to be seen, and then
another Probe Request frame after association, before we have a
signature for the client.

Most clients send lots of Probe Request frames (lots and lots and lots
of Probes, actually), but a few do not. ChromeOS is notably sparing in
sending Probe Request frames, it can take a long time before a signature
for a ChromeOS device is available.

Store the most recent Probe Request frame in struct hostapd_sta_info
tracking list. When a struct sta_info is created, move the Probe Request
frame information from struct hostapd_sta_info to struct sta_info.

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,
  vhtrxmcs:030cfffa,vhttxmcs:030cfffa,extcap:0000000000000040

5e993390f6 Initialize iface->sta_seen on allocation
Previously, struct hostapd_iface sta_seen list head was initialized only
when completing interface setup. This left a window for operation that
could potentially iterate through the list before the list head has been
initialized. While the existing code checked iface->num_sta_seen to
avoid this case, it is much cleaner to initialize the list when struct
hostapd_iface is allocated to avoid any accidental missing of the extra
checks before list iteration.

4424aa5d7d P2P: Fix D-Bus persistent parameter in group started event on GO
When starting a P2P GO, the struct p2p_go_neg_results may use
persistent_group == 2 to indicate use of persistent reconnect. Setting
ssid->p2p_persistent_group based on this did not take into account this
special case and that ended up in D-Bus code trying to encode 2 as a
DBUS_TYPE_BOOLEAN value which results in an assert from the library. Fix
this by setting ssid->p2p_persistent_group to 0 or 1 instead of raw
params->persistent_group value without any filtering.

This is similar to an earlier fix in commit
112fdee738 ('P2P: Fix D-Bus persistent
parameter in group started event') that addressed another code path in
sending out this D-Bus signal.

44a4c52c86 tests: Setup wlantest once for qosmap tests
Some tests call the check_qos_map() function more than once. Make sure
each test sets up wlantest only once before the first time the function
is called.

The wlantest setup sets the channel for the wlantest interface and
executes the wlantest executable. It is more efficient to do that only
once for each test.

ea19b39f60 Revert "nl80211: Remove duplicated check in nl80211_setup_ap()"
This reverts commit 647862eb60.

The second check of device_ap_sme looks like duplicated, but it isn't
actually. The trick is nl80211_create_monitor_interface may change that
variable value and the second evaluation may give a different result.

This definitely isn't a very clear code, but that change caused a
regression for drivers that:
1) Don't report NL80211_ATTR_DEVICE_AP_SME
2) Don't support monitor mode
3) Don't support subscribing for PROBE_REQ and/or ACTION frames
like brcmfmac. With such drivers hostapd doesn't start anymore.

660103eca9 nl80211: Use the monitor interface only without device_ap_sme support
The places using drv->use_monitor were already skipping creation of the
monitor interface if drv->device_ap_sme == 0. This means that the
monitor interface operations would not have worked anyway and it is safe
to set drv->use_monitor to zero for all such cases. This fixes an issue
with management frame subscription not happening properly for the case
where the AP SME is in the driver and the driver supports monitor
interfaces (for other purposes).

This commit also removes the check for monitor support and the
previously used workaround that cleared drv->use_monitor in
drv->device_ap_sme == 1 case if monitor interface was not supported
since that condition cannot occur anymore.

Fix some mistakes in the previous commit for adding QCA vendor commands

Note: The renamed enum value does not change the ABI, but the addition
of QCA_WLAN_VENDOR_ATTR_FTM_MEAS_INVALID in the beginning of enum
qca_wlan_vendor_attr_ftm_meas does renumber
QCA_WLAN_VENDOR_ATTR_FTM_MEAS_* values. The previous values were

this is a justifiable quick fix.

fcd85d9a3f Add QCA vendor commands/attributes for indoor location
Assign QCA vendor specific commands, attributes, and events for
supporting indoor location features.

These features include:

1. Fine timing measurement (FTM) - allows measurement of distance
between two stations. Based on IEEE P802.11-REVmc/D7.0, 11.24.6 FTM is
performed between two stations: one is an initiator, typically a client
that wants to measure distance to another AP, and one is a responder,
typically an AP which responds to measurement requests from other
clients. The responder can be configured to report its location, either
in absolute coordinates (LCI) or free-form description (LCR).

2. Angle of arrival (AOA) - allows measurement of azimuth and elevation
between two stations.

The above features can be combined to allow a station to get an accurate
indoor location.

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.
