PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for IEEE 802.11ad devices.
Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.
The function wpa_scan_res_match() was modified to match BSS according to
the pbss flag in the network block (wpa_ssid structure). When pbss flag
is set it will match only PCPs, and when it is clear it will match only
APs.

It does more than intended; apart from denying messages to that
particular interface it also denies all messages non-qualified with an
interface globally. This blocks messages completely unrelated to
wpa_supplicant, such as NetworkManager communication with the VPN
plugins.
From the dbus-daemon manual:
Be careful with send_interface/receive_interface, because the
interface field in messages is optional. In particular, do NOT
specify <deny send_interface="org.foo.Bar"/>! This will cause
no-interface messages to be blocked for all services, which is almost
certainly not what you intended. Always use rules of the form: <deny
send_interface="org.foo.Bar" send_destination="org.foo.Service"/>
We can just safely remove those rules, since we're sufficiently
protected by the send_destination matches and method calls are
disallowed by default anyway.

When a mesh point reconnects by starting from Authentication frame
sequence, the plink count was not decremented from its last connection.
This resulted in leaking peer link count and causing wpa_supplicant to
reject the connection after max_peer_links (default: 99) reconnects.
This was reproduced by pre-configuring 2 mesh points with mesh
credentials. Boot both mesh points and make sure they connect to each
other. Then in a loop reboot one of the mesh points after it
successfully connects while leaving the other mesh point up and running.
After 99 iterations the supplicant on mesh point that is not rebooting
will reject the connection request from the other mesh point.
Fix this by decrementing num_plinks when freeing a STA entry that is
still in PLINK_ESTAB state.

In cases where the bandwidth is not set when starting an AP/P2P GO,
the code tries to use 160 MHz or 80 MHz channels. As a result, the
AP/P2P GO configuration is set to use these channel widths even if
they are not available, which may results in failing to start the
AP/P2P GO.
Fix this by changing the AP/P2P GO configuration not to use VHT channels
when they are not available. In this case the AP/P2P GO will use a 40
MHz channel, if available, or a 20 MHz channel, if this is the maximum
available width.

When exchanging GAS frames with the AP, the initial response from the AP
may take a while to come, since the AP may need to fetch the info from a
server. The next fragments/comeback response frames should take much
less time since the AP already has all of the info, so the wait time
for these frames can be reduced.
In addition, some drivers, e.g., mac80211, try to combine ROC based flows,
to improve medium utilization. For example, if the requested ROC fits
entirely in a previous requested ROC they can be combined. Thus, reducing
the wait time for the next frames can improve medium utilization.

This adds a new command based Hotspot 2.0 icon retrieval option.
In short, here is the new command sequence:
1. REQ_HS20_ICON <bssid> <file-name>
2. event: RX-HS20-ICON <bssid> <file-name> <size>
3. GET_HS20_ICON <bssid> <file-name> <offset> <size>
(if needed, repeat with larger offset values until full icon is
fetched)
5. DEL_HS20_ICON <bssid> <file-name>
REQ_HS20_ICON is a new command that is analogous to HS20_ICON_REQUEST
with the slight difference that an entry to store the icon in memory is
prepared. The RX-HS20-ICON event has been augmented with BSSID,
file-name and size, and GET_HS20_ICON is used to retrieve a chunk of up
to <size> bytes of icon data at offset <offset>. Each chunk is returned
as a base64 encoded fragment, preceded by "HS20-ICON-DATA", BSSID, and
file-name as well as the starting offset of the data.
If there is no entry prepared for the icon when the ANQP result comes
back, hs20_process_icon_binary_file falls back to legacy behavior.
Finally the DEL_HS20_ICON command deletes (all) icons associated with
BSSID and file-name (there could be several if retries are used and they
have different dialog tokens).

During the sequence of exchanging GAS frames with the AP, the AP can
request to come back in X amount of time and resend the GAS request.
Previously, wpa_supplicant did not terminate the remain-on-channel
session, but rather waited until the requested comeback delay had
expired, and then tried to send the GAS frame (potentially to save the
time that is required to schedule a new remain on channel flow).
This might cause unnecessary idle time (can be close to 1000 ms) in
which the device might be off-channel. Ending the current
remain-on-channel session and then rescheduling makes better usage of
the time in this case.

This adds support for optional functionality to validate server
certificate chain in TLS-based EAP methods in an external program.
wpa_supplicant control interface is used to indicate when such
validation is needed and what the result of the external validation is.
This external validation can extend or replace the internal validation.
When ca_cert or ca_path parameter is set, the internal validation is
used. If these parameters are omitted, only the external validation is
used. It needs to be understood that leaving those parameters out will
disable most of the validation steps done with the TLS library and that
configuration is not really recommend.
By default, the external validation is not used. It can be enabled by
addingtls_ext_cert_check=1 into the network profile phase1 parameter.
When enabled, external validation is required through the CTRL-REQ/RSP
mechanism similarly to other EAP authentication parameters through the
control interface.
The request to perform external validation is indicated by the following
event:
CTRL-REQ-EXT_CERT_CHECK-<id>:External server certificate validation needed for SSID <ssid>
Before that event, the server certificate chain is provided with the
CTRL-EVENT-EAP-PEER-CERT events that include the cert=<hexdump>
parameter. depth=# indicates which certificate is in question (0 for the
server certificate, 1 for its issues, and so on).
The result of the external validation is provided with the following
command:
CTRL-RSP-EXT_CERT_CHECK-<id>:<good|bad>
It should be noted that this is currently enabled only for OpenSSL (and
BoringSSL/LibreSSL). Due to the constraints in the library API, the
validation result from external processing cannot be reported cleanly
with TLS alert. In other words, if the external validation reject the
server certificate chain, the pending TLS handshake is terminated
without sending more messages to the server.

p2p_go_save_group_common_freqs() called by p2p_go_configured() callback
in a case where a non-P2P AP mode operation is started in wpa_supplicant
(wpas_ap_wep test case). This callback should not have happened for
non-P2P case and the debug logs did not make it clear how this could
happen. In addition, it is unclear how this could be reproduced.
To avoid this type of issues, clear the wpa_s->ap_configured_cb pointer
as soon as the first call to the function happens. In addition, verify
that wpa_s->go_params is available before processing the GO configured
callback.

Connect radio work is sometimes delayed for a considerable duration if
there is an ongoing scan radio work. To avoid these delays abort the
ongoing scan on that interface before queuing a connect request. Upon a
scan done indication from the driver, connect radio work will be
scheduled.

This is needed to avoid hitting WEP/TKIP detection in
ibss_mesh_setup_freq() if the previous connection used WEP or TKIP.
Previously, that could have resulted in VHT and HT getting disabled for
the mesh connection.

A new network profile configuration parameter max_oper_chwidth=3 can be
used to specify preference to enable 80+80 MHz VHT channel for IBSS. If
that is set, the first 80 MHz segment is specified based on the
frequency parameter in the network profile and the second segment is
selected automatically (which will practically be limited to a single
possibility due to DFS requirements in most countries).

The new max_oper_chwidth and freq2 arguments to P2P_CONNECT, P2P_INVITE,
and P2P_GROUP_ADD control interface commands can be used to request
larger VHT operating channel bandwidth to be used than the previously
used maximum 80 MHz.

This extends the previous design that covered only the VHT 80 MHz cases
for VHT channel flags. New functions are introduced to allow 160 MHz
bandwidth cases to determine the center channel and check availability
of a 160 MHz channel.

Previously, MB IEs were parsed only from association event. Try to get
MB IEs from other management frames like Probe Response frames. The MB
IEs from the association event may not be up-to-date and in some cases
may actually be missing and updating the information based on other
frames can improve robustness of FST exchanges.

These wpa_supplicant test programs have not been maintained for years
and it would take significant effort to get these into working state.
Since there does not seem to be any real need for these based on lack of
maintenance, it is easier to just drop these tools for now.

When an invitation to join an existing group is accepted by the
peer device, set p2p_go_wait_client to the current time so
that wpas_p2p_in_progress() would return != 0, thus preventing
P2P CSA, scanning etc., that would interfere with the peer
device connection.

Some drivers do not support having two station interfaces, so the fact
that wpa_supplicant always creates a new interface in station mode, even
if it will be used as another type of interface, may prevent
wpa_supplicant from creating new interfaces. Allow setting the interface
type when a new interface is created so that interfaces of supported
types can be created.
Currently supported types are station ("sta") and AP ("ap"). If the
interface type is not specified, a station interface will be created.

When an AP interface it created, it is also setup and subscribes
for management frames etc. However, when the interface is added by
wpa_supplicant, setting up for AP operations is redundant because
it will be done by wpa_supplicant on wpa_drv_init() when setting
the interface mode to AP.
In addition, it may cause wpa_supplicant to fail initializing the
interface as it will try to subscribe for management frames on this
interface but the interface is already registered.
Change this, so when adding an AP interface, make setting up the AP
optional, and use it only when the interface is added by hostapd but not
when it is added by wpa_supplicant.

When clearing pending TX action to start a new P2P operation like
P2P_FIND or P2P_LISTEN, wpas_p2p_action_tx_clear() was used to clear
the send action work. However, in cases where the action work has wait
time, it is not cleared immediately but only after the wait time ends.
This may cause delay in starting the P2P operation.
Fix that by always clearing the send action work immediately on these
P2P commands that result in immediate P2P state change and practically
stopping a previous operation, if one was pending.

This allows offloaded roaming to inform user space of the change in IP
subnet post roaming. The device may have roamed to a network which is in
a different subnet which will result in IP connectivity loss. Indicating
the change in subnet enables the user space to refresh the IP address or
to perform IP subnet validation if unknown status is indicated.
The driver indication is reported with a new event from wpa_supplicant
in the following format:
CTRL-EVENT-SUBNET-STATUS-UPDATE status=<0/1/2>
where
0 = unknown
1 = IP subnet unchanged (can continue to use the old IP address)
2 = IP subnet changed (need to get a new IP address)

Commit 2a6f78fbbe ('Do not re-associate on
SELECT_NETWORK to current network') started skipping all SELECT_NETWORK
connection steps if the selected network had already been selected
previously. This happened regardless of whether the connection was
already established. This is not necessarily desirable for all cases
where there is no immediate action to even try to connect (e.g., long
wait for the next scan).
Speed this up by allowing the SELECT_NETWORK operation to get started if
there is no connection or ongoing connection attempt with the selected
network.

Mesh Points themselves have capability to support VHT as long as
hardware supports it. However, supporting VHT in mesh mode was disabled
because no one had clearly tested and confirmed its functionality. Since
VHT80 has now been verified to work with ath10k QCA988X driver and
mac80211_hwsim, enable VHT support in mesh mode.
