6428d0a71f Do not start wpa_radio work during externally triggered scan
If an external program triggers a scan, wpa_supplicant does not have a
wpa_radio work item for this operation to protect against other
offchannel operations. This can result in operations failing, so try to
avoid damage by not starting any new wpa_radio work items during a scan
that was started by another process.

6470f471e4 Remove unneeded scan delay on connection-in-progress
This type of protection against concurrent connection and scan
operations is now enforced through the wpa_radio work mechanism, so this

b9e6d7001d Use radio work for GAS requests
Avoid concurrent GAS operations with any other exclusive use of the
radio by using the radio work queuing mechanism. This replaces some of

b1ae396f59 Add framework for exclusive radio operations
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.

466bcf99c3 Remove some unnecessary EAPOL port (un)authorized callbacks
If the port status did not change or would not need to get an update
after portEnabled changes, there is no need to try to set the driver to
use the same value it is already using based on the previous state.
Remove such calls to reduce number of operations during reassociation.
In addition, this cleans up the debug log by removing unnecessary
duplicated entries.

949938aadf Ask driver to report only new scan results if requested
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.

Negotiation Request frame. Offchannel Listen mode operation on the P2P

acknowledgement on the operating channel, so need to disconnect from the
group which removes the GO-to-P2P Client part of the discoverability
exchange in practice.
