It may not always be desirable to trigger reassociation or network
change based on scan results from externally to wpa_supplicant trigger
scan operations. Skip network selection and roaming determination if the
received scan result is known to be triggered by something external to

request wpa_supplicant to determine the best network.

This parameter was not really used for anything else apart from a debug

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

that the driver indicates as enabled and that are within the specified

An INTERFACE_DISABLED event received on an interface that is
currently operating a P2P GO means that the group session ended.
In such a case, if the interface was dynamically added remove it, and
if not, remove all the network blocks that are temporary, assuming
that if needed a new session will be started by an external entity.
The use case was triggering rfkill (both SW and HW). This case popped up
as part of a testing cycle, where after a toggle in the rfkill state,
the result was that the interface was not deleted, but on the other hand
the wpa_supplicant did not configure the kernel to re-start the AP
functionality again.
Signed-hostap: Ilan Peer <ilan.peer@intel.com>
On scan results event if a concurrent P2P scan was triggered previously,
scan results processing is canceled, p2p_find executed, and a new sta
scan is triggered (pending scan). However, this new sta scan does not
restore the scan_req value of the previous scan (whose scan result has
been canceled).
If we are currently connected to an AP and use ap_scan=2, the new
triggered scan will cause an associtation-without-scan in
wpa_supplicant_scan:
(ap_scan == 2 & scan_req != MANUAL_SCAN_REQ)
=> wpa_supplicant_assoc_try()
causing an association error and a disconnection.

While starting from PNO start context, the scheduled scan was not

While sched_scan is in progress and a legacy scan comes on the

delayed and we will send out the scan command before the wpa_s->scanning
