183d3924cf WPS: Add option for using random UUID
If the uuid configuration parameter is not set, wpa_supplicant generates
an UUID automatically to allow WPS operations to proceed. This was
previously always using an UUID generated from the MAC address. This
commit adds an option to use a random UUID instead. The type of the
automatically generated UUID is set with the auto_uuid parameter: 0 =
based on MAC address (default; old behavior), 1 = random UUID.

The last SD Response frame fragment is not going to be followed by
another Action frame from the peer, so remove the 200 ms wait time from
the offchannel TX command in that case. This avoids leaving a 200 ms
lock on the radio to remain on the channel unnecessarily.

c5fee1604b FT: Schedule wpa_ft_rrb_rx() through eloop in intra-process communication
With AP-AP communication, when hapd0 sends a packet, hapd1 can receive
it immediately and send a response. But hapd0 will only read and process
the response after it has returned from the sending context, that is
entered eloop again. So one does not need to consider the RX function of
the reply to run for the request sending hapd before the send calling
function has returned.

Previously, with intra-process communication, the packet is not
scheduled through eloop. Thus the RX handler of the reply might be run
while the sending context of the original request has not returned.
This might become problematic, e.g., when deferring a management frame
processing until an RRB response is received and then have the request
restarted and finished before the original request handling has been
stopped.

I'm not aware of any concrete bug this is currently triggering but came
across it while thinking of FT RRB AP-AP sequence numbering.

I think the non-eloop scheduling approach might be error-prone and thus
propose to model it more closely to the way the message would be
received from a socket. Additionally, this ensures that the tests model
AP-AP communication more closely to real world.

Solution: queue these packets through eloop.

775e986d5f hostapd: Fix crash on consecutive channel switch failures
With multiple interface like AP and station which is already
associated to some other AP, when we try to do channel switch
for the AP mode (different from the operation channel support of
station) and if the AP channel switch fails continously (including
the fallback channel switch), results in a crash due to NULL pointer
dereference. This is because hostapd_deinit_driver() assigns the
driver context (drv_priv) to NULL as we are not able to bring up
the interface with a new channel

2c0ac6d613 P2P: Run full P2P_FIND scan after pending scan completes
If a P2P_FIND command is issued for running the initial full scan and
the attempt to start that full scan fails, the previous behavior was to
wait for the ongoing scan to complete and then continue p2p_find scan
iterations. However, this continued with the social channels scan
instead of the initial full scan. This could end up missing the full
scan completely.

Fix this by marking the full scan pending if the new scan cannot be
started immediately. Then start the initial full scan after the ongoing
scan completes before moving to social channel only scan iterations.
This applies both for the P2P_FIND_START_WITH_FULL (no specific
frequency set) and P2P_FIND_PROGRESSIVE cases since both of them start
with a single full scan round.

7cbb5f1a44 DFS: Handle pre-CAC expired event
As FCC DFS requirement does not explicitly mention about the validity of
the (pre-)CAC when channel is switched, it is safe to assume that the
pre-CAC result will not be valid once the CAC completed channel is
switched or radar detection is not active on the (CAC completed) channel
within a time period which is allowed (10 seconds - channel switch time)
as per FCC DFS requirement.

Use the new driver event to allow the driver to notify expiry of the CAC
result on a channel. Move the DFS state of the channel to 'usable' when
processing pre-CAC expired event.  This means any future operation on
that channel will require a new CAC to be completed. This event is
applicable only when DFS is not offloaded to the kernel driver.

processing CAC completion event with devices where DFS is not offloaded,
when in state other than enabled make sure the configured DFS channel is
