57b38882e5 P2P: Add P2P_GROUP_MEMBER command to fetch client interface address
This allows local GO to fetch the P2P Interface Address of a P2P Client
in the group based on the P2P Device Address for the client. This
command should be sent only on a group interface (the same peer may be
in multiple concurrent groups).

Usage:
P2P_GROUP_MEMBER <P2P Device Address>

Output:
<P2P Interface Address>

0ee8925098 P2P: Trigger event when invitation is accepted
Trigger an event when wpa_supplicant accepts an invitation to re-invoke
a persistent group. Previously wpa_supplicant entered group formation
without triggering any specific events and it could confuse clients,
especially when operating with a driver that does not support
concurrency between P2P and infrastructure connection.

bd86ea0808 nl80211: Get rid of unused assignment warning

its result was stored into the local variable and not checked, static

51269b386a tests: Add RRM tests
1. Add tests for hostapd neighbor database and neighbor report and
   request. Remove the partial neighbor report request test from
   test_wpas_ctrl.py since they are now covered more completely in
   test_rrm.py.
2. Add LCI request test.
3. Add FTM range request signaling test. This covers only the control
   interface commands and measurement request/response exchange for now.
   Full end-to-end functionality requires support of station reporting
   RRM capability.

220754c553 hostapd: Add FTM range request
Add FTM range request via RRM. The AP sends Radio measurement request
with FTM range request as a request for the receiving STA to send FTM
requests to the given list of APs. The neighbor report part of the
request is taken from the neighbor database.

The control interface command is:

REQ_RANGE <dst addr> <rand_int> <min_ap> <responder> [<responder>..]

dst addr: MAC address of an associated STA
rand_int: Randomization Interval (0..65535) in TUs
min_ap: Minimum AP Count (1..15); minimum number of requested FTM ranges
	between the associated STA and the listed APs
responder: List of BSSIDs for neighboring APs for which a measurement
	is requested

601e55726c tests: Add P2P invitation coverage during p2p_find
The new persistent_group_peer_dropped3 test case is similar to
persistent_group_peer_dropped with the difference being in the
responding device (the one from which the persistent group information
is dropped) is not issued a separate P2P_LISTEN command and instead, a
single P2P_FIND is used through the exchange to verify that this
operation does not get stopped unexpectedly. This is a regression test
case to verify that P2P_PENDING_INVITATION_RESPONSE case ends up calling
p2p_check_after_scan_tx_continuation() in non-success case. It should be
noted that this is dependent on timing: Action frame TX request needs to
occur during the P2P_FIND Search phase (scan). As such, not every
execution of this test case will hit the previous issue sequence, but
that should be hit every now and then.

3433721c5f P2P: Continue p2p_find after sending non-success Invitation Response
This was previously handled for the case where the non-success
Invitation Response frame was sent out during the Listen phase. However,
in the case the Action frame TX ended up getting scheduled when the
Search phase scan had already started (e.g., due to the driver reporting
Invitation Request RX late enough for the Listen-to-Search transition
having already started), the postponed Action frame TX status processing
did not cover the specific case of non-success Invitation Response. This
could result in the p2p_find operation getting stopped (stuck in SEARCH
state) unexpectedly.

Fix this by calling p2p_check_after_scan_tx_continuation() from
Invitation Response TX callback handler if the invitation was rejected.

3560b32ca3 Fix race condition with PNO stop followed immediately by PNO start
Commit dd271857a5 ('Skip normal scan when
PNO is already in progress') fixed issues with normal scans getting
rejected by the driver when PNO scan is already running. The part about
skipping such a scan request is fine, but the part about clearing
wpa_s->pno back to 0 in EVENT_SCHED_SCAN_STOPPED handler is problematic.

If PNO is stopped ("SET pno 0") and then restarted ("SET pno 1")
immediately, it is possible for the EVENT_SCHED_SCAN_STOPPED event from
the stopping part to be received only after the new PNO instance has
been started. This would have resulted in clearing wpa_s->pno and the
driver and wpa_supplicant getting out of sync. This would then prevent
PNO from being stopped with "SET pno 0" (that fails if wpa_s->pno == 0).

Fix this race condition by reverting the wpa_s->pno = 0 addition from
the EVENT_SCHED_SCAN_STOPPED handler.
