59b45d1afe P2P NFC: Add processing of P2P client while NFC handover case
Instead of automatically triggering a connection, provide an indication
of one of the devices being a P2P client to upper layers to allow user
to determine what to do next.

25ef8529c1 P2P: Add support for IP address assignment in 4-way handshake
This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.

The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:

ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100

DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.

41f9ffb635 WPS NFC: Build new style carrier record for connection handover request

instead of the full connection handover request message to allow
external components to decide whether to negotiate which alternative
carrier is used. This updates the carrier record contents to the new
design to include Enrollee public key hash and provides this as a
carrier record instead of full message. An external program is expected
to be used to build the full NFC connection handover message with
potentially other alternative carrier records included.

253f2e3795 P2P: Apply unsafe frequency rules to available channels
This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.

If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

7b2c42f8b9 hostapd: Fix PMF robust Action frame processing rules
Due to misplaced parenthesis, unprotected not-Robust Action frames
(e.g., Public Action frames) were dropped in handle_assoc() when such
frames were received during an association that had negotiated use of
PMF. This is not correct since only unprotected Robust Action frames
were supposed to be handled in this way.

This would have broken any Public Action frame use during PMF
association, but such frames were not really supposed to be used
currently (ANQP as the only possible use case should really use
protected dual option in such case).

cf70d2981d wpa_supplicant: Schedule PNO on completion of ongoing sched_scan
When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)
gets cancelled. Issuing cancel sched_scan and start PNO scan
one after another from pno_start() would lead wpa_supplicant to clear
wps->sched_scanning flag while getting sched_scan stopped event
from driver for cancel sched_scan request. In fact, PNO scan will
be in progress in driver and wpa_s->sched_scanning will not be set
in such cases.

In addition to this change, RSSI threshold limit is passed as part of
start sched_scan request. This was previously set only in pno_start(),
but the same parameter should be available for generic sched_scan calls
as well and this can now be reached through the new PNO start sequence.
