mac_addr=2 and preassoc_mac_addr=2 parameters can now be used to
configure random MAC address to be generated by maintaining the OUI part
of the permanent MAC address (but with locally administered bit set to

mac_addr=1 and preassoc_mac_addr=1, respectively.

This adds experimental support for wpa_supplicant to assign random local
MAC addresses for both pre-association cases (scan, GAS/ANQP) and for
connections. MAC address policy for each part can be controlled
separately and the connection part can be set per network block.
This requires support from the driver to allow local MAC address to be
changed if random address policy is enabled. It should also be noted
that number of drivers would not support concurrent operations (e.g.,
P2P and station association) with random addresses in use for one or
both.
This functionality can be controlled with the global configuration
parameters mac_addr and preassoc_mac_addr which set the default MAC
address policies for connections and pre-association operations (scan
and GAS/ANQP while not connected). The global rand_addr_lifetime
parameter can be used to set the lifetime of a random MAC address in
seconds (default: 60 seconds). This is used to avoid unnecessarily
frequent MAC address changes since those are likely to result in driver
clearing most of its state. It should be noted that the random MAC
address does not expire during an ESS connection, i.e., this lifetime is
only for the case where the device is disconnected.
The mac_addr parameter can also be set in the network blocks to define
different behavior per network. For example, the global mac_addr=1 and
preassoc_mac_addr=1 settings and mac_addr=0 in a home network profile
would result in behavior where all scanning is performed using a random
MAC address while connections to new networks (e.g.,
Interworking/Hotspot 2.0) would use random address and connections to
the home network would use the permanent MAC address.

Previously, the shorter startWhen value was used based on build
parameters (i.e., if WPS was enabled). This is not really ideal and the
knowledge of WPS use can be provided to the EAPOL state machine to allow
this (and similar WPS workarounds) to be done only when the association
is for the purpose of WPS.
Reduce the default startWhen value from 3 to 2 seconds for non-WPS case
since WPS builds have likely received most testing for the past years
with the 1 second value and there is no strong justification for forcing
the longer 3 second wait should a frame be lost or something else
require the EAPOL-Start to initiate operation after a connection.

Performing a P2P Device flow such as p2p_listen or
p2p_find, can degrade the performance of an active interface
connection, if the listen frequency is different than the
frequency used by that interface.
To reduce the effect of P2P Device flows on other interfaces,
try changing the listen channel of the P2P Device to match the
operating channel of one of the other active interfaces. This change
will be possible only in case that the listen channel is not forced
externally, and will be delayed to a point where the P2P Device
state machine is idle.
The optimization can be configured in the configuration file and

When the number of frequencies supported by the kernel is bigger than
one, and there is a need to pick a frequency for a new flow such as P2P
GO Negotiation or P2P Invitation, the flow should be able to pick the
best frequency among all the frequencies currently used by the device.
In order to prioritize between the currently used frequencies, add
the ability to collect additional data about each used frequency
(if the frequency is used by a station interface or P2P Client)
and when needed select the best frequency, where:
1. Infrastructure interfaces have highest priority
2. P2P Client interfaces have higher priority over AP/GO
interfaces.
The rational is that the frequency of an AP/GO can change while
that of a station interface cannot.

The normal scan counter is used to trigger a few normal scans before a

not reset this counter, so we will keep using sched scans.

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.

Fix this by using an eloop timeout to free remove the P2P group so that
wpa_supplicant_create_ap() and especially wpa_supplicant_associate()
callers do not need to know about interface getting possibly removed. In
addition, move the P2P specific code into p2p_supplicant.c where it
really belongs. This allows the already existing group formation timeout
to be used by reducing the timeout to zero.

Record all generated per-client PSKs in the persistent group network
block and configure these for the GO Authenticator whenever re-starting
the persistent group. This completes per-client PSK support for
persistent groups.

There were some code paths that allowed obsolete configuration data
pointer to be maintained within EAPOL supplicant in case a network was
removed while not connection to it (i.e., wpa_s->current_ssid not
pointing to the network that was removed). This could result in use of
freed memory, e.g., from eap_sm_notify_ctrl_attached() when a new
control interface connected prior to the EAPOL supplicant configuration
pointer got updated.

4-way handshake may fail under extremely noisy environment and if this
happens during P2P group formation, the 10 second extra delay added in
wpas_auth_failed() can result in running over the 15 second timeout.
Avoid this by skipping the delay mechanism in wpas_auth_failed() for the
P2P group formation case. The P2P formation timeout will take care of
stopping the attempts if the failure condition does not get resolved.

Some driver interfaces may not support the get_radio_name() design and
get_shared_radio_freqs() needs to be aware of such possibility when
determining shared radio frequencies.
Signed-hostap: Jouni Malinen <j@w1.fi>
There are devices that can operate several channels concurrently.
Change shared_vif_oper_freq() to get_shared_radio_freqs() that can
return an array of frequencies currently used by all the virtual
interfaces that share the same radio.
In addition, move it to wpa_supplicant.c, so it can be used by other
modules.

Previously, drivers only reported if they support multiple concurrent
channels, but did not report the maximum number of supported channels.
Add this reporting to the driver capabilities and add the implementation
to driver_nl80211.
