If P2P was disabled (e.g., due to driver not supporting it or through
p2p_disabled=1 configuration), setting Wi-Fi Display parameters could
result in segmentation fault when the WFD IE is updated without the P2P
module being initialized. Fix this by skipping the update if P2P module
is not in use. In addition, show Wi-Fi Display as disabled in "GET
wifi_display" and refuse to enable it with "SET wifi_display 1" if P2P
is not enabled.

When the NFC connection handover message received from a peer indicates
that the peer is operating as a GO on a specific channel, use that

It is more useful to be able to build a single NFC carrier record
instead of the full connection handover request message to allow
external components to decide whether to negotiate which alternative
carrier is used. This updates the carrier record contents to the new
design to include Enrollee public key hash and provides this as a
carrier record instead of full message. An external program is expected
to be used to build the full NFC connection handover message with
potentially other alternative carrier records included.

When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)
gets cancelled. Issuing cancel sched_scan and start PNO scan
one after another from pno_start() would lead wpa_supplicant to clear
wps->sched_scanning flag while getting sched_scan stopped event
from driver for cancel sched_scan request. In fact, PNO scan will
be in progress in driver and wpa_s->sched_scanning will not be set
in such cases.
In addition to this change, RSSI threshold limit is passed as part of
start sched_scan request. This was previously set only in pno_start(),
but the same parameter should be available for generic sched_scan calls
as well and this can now be reached through the new PNO start sequence.

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

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.

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

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.

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.
