The new default value (from 300 to 60 seconds) makes the internal P2P
peer list somewhat faster to react to peers becoming unreachable while
still maintaining entries for some time to avoid them disappearing
during user interaction (e.g., selecting a peer for a connection or
entering a PIN).

Scan request failures are observed in wpa_supplicant debug log when
Android framework starts PNO scan in driver via ctrl interface command
'set pno 1' and wpa_supplicant also tries to issue a scan request after
PNO has started in the driver.
Some drivers may reject a normal scan request when PNO is already in
progress. wpa_supplicant should consider PNO status before issuing start
scan request to the driver. Otherwise, wpa_supplicant will get failures
from driver for the scan request and it will end up rescheduling scan
request in periodic interval and get a start scan request failure for
each attempt.
In order to avoid unnecessary scan attempt when PNO scan is already
running, PNO status is checked before issuing scan request to driver.

A P2P Device while in the Listen state waiting to respond for the
obtained group negotiation request shall give a fair chance for other
concurrent sessions to use the shared radio by inducing an idle time
between the successive listen states. However, if there are no
concurrent operations, this idle time can be reduced.

Verify that PD Request followed by GO Negotiation Request is enough to
learn the Listen frequency of the peer.
Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
Previously, GO Negotiation Request frame was used to update a peer entry
if only a Probe Request from that peer had been received. However, it
would be possible, even if unlikely, for a peer to be discovered based
on receiving Provision Discovery Request frame from it and no Probe
Request frame. In such a case, the Listen frequency of the peer would
not be known and group formation could not be (re-)initialized with that
peer. Fix this by allowing the GO Negotiation Request frame to update
peer entry if the current peer entry does not include Listen or
Operating frequency.

To test the code under the influence of time jumps, add the option
(--timewarp) to the VM tests to reset the clock all the time, which
makes the wall clock time jump speed up 20x, causing gettimeofday()

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).

This patch resets the static interface_count to zero in case of
wpa_supplicant_driver_init() call for wpa_s which is in
INTERFACE_DISABLED state. This interface_count is used for the delay of
the scan which is now minimal for dynamically added interfaces. This may
collide with a scan for another interface, but the same is true for any
chosen delay in this scenario. Also the state change to DISCONNECTED is
moved to wpa_supplicant_driver_init() so it will move from
INTERFACE_DISABLED to INACTIVE when there are no enabled networks.

Depending on the implementation, the scheduled scan may not give results
quickly when in DISCONNECTED state. This patch resets
wpa_s::normal_scans upon entering to the INTERFACE_DISABLED state so a
normal scan is assured upon going to DISCONNECTED state after the
interface has been re-enabled. This mainly solves a long reconnect time
observed upon repeated kernel driver reloads, i.e., third reload
resulted in a scheduled scan.

Since wlantest is a separate process that is not synchronized with rest
of the test components, there can be some latency in it having the STA
entries and counters updated. There is a race condition between this
happening and then test script clearing or fetching data. Make this race
condition less likely to cause bogus test failures by adding some wait
between these operations.

In addition to running the FLUSH command again, the pending monitor
interface events need be cleared in case the driver was running a scan
when reset() is called. This avoids issues, e.g., with discovery_dev_id
failing due to an unexpected P2P-DEVICE-FOUND event that was generated
by the pending scan operation that had not yet complete when the first
dump_monitor() call in reset() happened.

If we already know the SSID of the P2P group we are trying to join, use
that SSID to limit scan responses and BSS selection since we do not
really look for any other network in this case. In addition, this can
fix cases where the peer has just changed its SSID (e.g., started a new
group) and there may be multiple BSS entries for the same BSSID.

It was possible for the previous test case to leave unexpected BSS or
P2P peer table entries if a scan was in progress when the FLUSH command
was used. This could result in test failures, e.g., when running
discovery_dev_type_go followed by discovery_group_client where a P2P
peer was discovered on another channel at the end of the former test
case from a scan that was running durign the FLUSH operation that was
supposed to remove all P2P peers. This could result in
discovery_group_client failing due to dev[2] trying to send the
discoverability frame on incorrect channel (the one learned in the
previous test case) since discover_peer() skipped a new device
discovery. Fix this by running FLUSH operation again if a pending scan
operation is detected during the first FLUSH operation.

It is possible for the configuration to be temporarily invalid when

This reverts commit 792c8877c3
('P2P: Send GO Negotiation Confirm without wait').
Some drivers rely on the wait period for sending packets on the
off-channel. If the wait value is small, there's a race condition where
the driver ROC might complete before the packet was sent out. This
doesn't impede other drivers, as the wait is cancelled when a
Tx-completion arrives from the remote peer.

The missing call to scan_action_done() may keep us off-channel for 250
ms following sending GO Negotiation Response. In case the operating
channel is different from this channel and we're GO, a race could lead
to start beaconing while off-channel. This could potentially cause the
Beacon frames to go out on incorrect channel with some drivers.
