This makes it more convenient for test scripts to change parameters for

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.

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

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

Unfortunately, these are all connected, so the patch can't be split

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

ctrl_iface response and unsolicited event messages from getting mixed

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.
