This part is missing from IEEE Std 802.11ai-2016, but the lack of DHss

IEEE Std 802.11ai-2016 had missed a change in the Pairwise key hierarchy
clause (12.7.1.3 in IEEE Std 802.11-2016) and due to that, the previous

of a boolean identifying whether SHA256 is used.

Enable use of FT RRB without configuring each other AP locally. Instead,
broadcast messages are exchanged to discover APs within the local
network.
When an R0KH or R1KH is discovered, it is cached for one day.
When a station uses an invalid or offline r0kh_id, requests are always
broadcast. In order to avoid this, if r0kh does not reply, a temporary
blacklist entry is added to r0kh_list.
To avoid blocking a valid r0kh when a non-existing pmk_r0_name is
requested, r0kh is required to always reply using a NAK. Resend requests
a few times to ensure blacklisting does not happen due to small packet
loss.
To free newly created stations later, the r*kh_list start pointer in
conf needs to be updateable from wpa_auth_ft.c, where only wconf is
accessed.

This adds a counter and adds sequence numbering to FT RRB packets. The
sequence number is checked against r0kh/r1kh sequence number cache.
Special attention is needed in case the remote AP reboots and thus loses
its state. I prefer it to recover automatically even without synchronized
clocks. Therefore an identifier called dom is generated randomly along the
initial sequence number. If the dom transmitted does not match or the
sequence number is not in the range currently expected, the sender is asked
for a fresh confirmation of its currently used sequence numbers. The packet
that triggered this is cached and processed again later.
Additionally, in order to ensure freshness, the remote AP includes an
timestamp with its messages. It is then verified that the received
messages are indeed fresh by comparing it to the older timestamps
received and the time elapsed since then. Therefore FT_RRB_TIMESTAMP is
no longer needed.
This assigns new OUI 00:13:74 vendor-specific subtype 0x0001 subtypes:

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.

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
