This adds experimental support for wpa_supplicant to assign random local
MAC addresses for both pre-association cases (scan, GAS/ANQP) and for
connections. MAC address policy for each part can be controlled
separately and the connection part can be set per network block.
This requires support from the driver to allow local MAC address to be
changed if random address policy is enabled. It should also be noted
that number of drivers would not support concurrent operations (e.g.,
P2P and station association) with random addresses in use for one or
both.
This functionality can be controlled with the global configuration
parameters mac_addr and preassoc_mac_addr which set the default MAC
address policies for connections and pre-association operations (scan
and GAS/ANQP while not connected). The global rand_addr_lifetime
parameter can be used to set the lifetime of a random MAC address in
seconds (default: 60 seconds). This is used to avoid unnecessarily
frequent MAC address changes since those are likely to result in driver
clearing most of its state. It should be noted that the random MAC
address does not expire during an ESS connection, i.e., this lifetime is
only for the case where the device is disconnected.
The mac_addr parameter can also be set in the network blocks to define
different behavior per network. For example, the global mac_addr=1 and
preassoc_mac_addr=1 settings and mac_addr=0 in a home network profile
would result in behavior where all scanning is performed using a random
MAC address while connections to new networks (e.g.,
Interworking/Hotspot 2.0) would use random address and connections to
the home network would use the permanent MAC address.

The new "scan_id=<comma separated list of network ids>" parameter can

Performing a P2P Device flow such as p2p_listen or

To reduce the effect of P2P Device flows on other interfaces,
try changing the listen channel of the P2P Device to match the
operating channel of one of the other active interfaces. This change

It should be noted that these commands are not exclusively used for P2P
or in the global context, so use of these commands through the global
control interface for operations that are specific to a single interface
have undefined behavior and that behavior may change in the future. As
such, these are recommend only for operations that are in the global
context (e.g., for P2P management).

Previously, only the last response data was kept in memory. This
increases that to hold up to two last responses to allow some more
parallel operations to be requested. In addition, the response data is
now freed as soon as the external program has fetched it.

This can be used to limit which channels are scanned using the specified
list of frequency ranges in the same format that the SCAN command uses.

The new control interface command RADIO_WORK can be used by external
programs to request radio allocation slots from wpa_supplicant if
exclusive radio control is needed, e.g., for offchannel operations. If
such operations are done directly to the driver, wpa_supplicant may not
have enough information to avoid conflicting operations. This new
command can be used to provide enough information and radio scheduling
to avoid issues with such cases.
Signed-hostap: Jouni Malinen <j@w1.fi>
The new radio work item concept can be used to request time for an
operation that requires exclusive radio control, e.g., a scan. Once the
radio is available, the registered callback function will be called.
radio_work_done() must be called once the exclusive radio operation has
been completed, so that the radio is freed for other operations. The
special case of deinit=1 is used to free the context data during
interface removal. That does not allow the callback function to start
the radio operation, i.e., it needs to free the allocated resources
and return.

The newer wpa_dbg() print includes the same information in a more
convenient form, so remove the duplicate RX ctrl_iface hexdump in the
cases where there is no key material in the control interface commands
(the possible-key-material case is still using wpa_hexdump_ascii_key).

If the BSS table within wpa_supplicant is flushed, request the driver to
flush its own scan result table during the next scan. This can avoid
unexpected old BSS entries showing up after BSS_FLUSH or FLUSH command
in cases where the driver may maintain its internal cache of scan
results (e.g., cfg80211 BSS table persists at least for 15 seconds).
In addition to doing this automatically on BSS_FLUSH/FLUSH, a new SCAN
command argument, only_new=1, can be used to request a manual scan
request to do same. Though, it should be noted that this maintains the
BSS table within wpa_supplicant. BSS_FLUSH followed by SCAN command can
be used to clear all BSS entries from both the driver and
wpa_supplicant.

This allows users of wpa_supplicant control interface to figure out when
their specific scan command has been started and completed. For example:
CTRL-EVENT-SCAN-STARTED

CTRL-EVENT-SCAN-RESULTS
CTRL-EVENT-SCAN-STARTED id=3

The new freq=<frequency ranges> parameter to the SCAN command can be
used to request a scan to be performed on the specified set of channels
instead of on all channels. For example, "wpa_cli scan
freq=2400-2500,5180" would scan channels 1-14 and 36. Only the channels
that the driver indicates as enabled and that are within the specified
ranges are included in the request.

The BSS table, scan timeout, and related functionality should use
monotonic time since they care about relative values (age) only.
Unfortunately, these are all connected, so the patch can't be split
further. Another problem with this is that it changes the driver wrapper
API. Though, it seems only the test driver is using this.

While starting from PNO start context, the scheduled scan was not
setting the flag wpa_s->scanning. This was resulting in the subsequent
SCAN command to proceed further and send command to nl80211/cfg80211.
The expected behavior of cancelling sched_scan was not happening here.
While sched_scan is in progress and a legacy scan comes on the
cli/socket, the sched_scan is cancelled and normal scan is allowed to
continue. However, sometimes sched_scan cancelled event comes a bit
delayed and we will send out the scan command before the wpa_s->scanning
is cleared. Instead, reschedule the incoming scan req if the
wpa_s->scanning shows that it is still in progress.

There are use cases requesting the host driver to initiate the TDLS
setup with the peer only when configured by the external applications.
Thus, enable this control by tdls_external_control=1 and pass the
requisite information for the specific TDLS operation to the driver
on the request from such use cases.
This operation mode expects the driver to initiate TDLS link
automatically based on signal strength and traffic to a peer and tear
down links whenever they are not used or suitable due to signal strength
etc. The list of peers with which such operations are to be performed
are provided with the TDLS driver operations.

This is what the original implementation did years ago, but the move to
using separate control interface backends re-ordered the implementation
to process EAPOL notification first. Use a registered timeout to allow
the ctrl_iface response to be sent out first to get somewhat faster
response time and to avoid pending operations that could result in
ctrl_iface response and unsolicited event messages from getting mixed
up.

Previously, GO considered the group to be fully re-invoked after
starting beaconing on successful invitation exchange. This would leave
the group running until idle timeout (which may not be enabled) or
explicit removal if the client fails to connect for any reason. Since
the client is expected to connect immediately after the invitation
exchange that ends with status=0 (i.e., either client initiated the
exchange or it responded with success), extend group formation timeout
to cover that period until the first successfully completed data
connection. This allows the GO to remove the group automatically if the
client devices does not connect within
P2P_MAX_INITIAL_CONN_WAIT_GO_REINVOKE (15) seconds.

The new control interface command P2P_REMOVE_CLIENT <P2P Device

"wpa_cli p2p_set per_sta_psk <0/1>" can now be used to disable/enable
use of per-device PSKs in P2P groups. This is disabled by default.
When enabled, a default passphrase is still generated by the GO for
legacy stations, but all P2P and non-P2P devices using WPS will get
a unique PSK.
This gives more protection for the P2P group by preventing clients from
being able to derive the unicast keys used by other clients. This is
also a step towards allowing specific clients to be removed from a group
reliably without having to tear down the full group to do so.
