07e2de3193 wpa_supplicant: Allow OpenSSL cipherlist string to be configured
The new openssl_cipher configuration parameter can be used to select
which TLS cipher suites are enabled for TLS-based EAP methods when
OpenSSL is used as the TLS library. This parameter can be used both as a
global parameter to set the default for all network blocks and as a
network block parameter to override the default for each network
profile.

a313d17de9 Extend random MAC address support to allow OUI to be kept
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
1). Other than that, these values result in similar behavior with
mac_addr=1 and preassoc_mac_addr=1, respectively.

c267753ba2 Add support for using random local MAC address
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.

This is not really necessary check, but it keeps a static analyzer

removing the increment is less likely to cause problems when new entries

e3bd6e9dc0 P2P: Use another interface operating channel as listen channel
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
is disabled by default.

d3b204694a P2P: Make the default p2p_find delay value configurable
This makes the p2p_find default delay value configurable as
p2p_search_delay parameter through the configuration file (and through
control interface "SET p2p_search_delay <value>" on the P2P management
interface.

This parameter controls the number milliseconds of extra delay that is
added between search iterations when there is a concurrent operation in
progress. This can be used, e.g., p2p_search_delay=100 to make p2p_find
friendlier to concurrent operations by avoiding it from taking 100% of
the radio resources. The default value is the previous default, i.e.,
500 ms. Smaller values can be used to find peers more quickly at the
cost of larger effect to concurrent operations while a larger value
leaves more time for the concurrent operations at the cost of making
device discovery take longer time.

The optional p2p_find delay argument can still be used to override the
search delay for each search operation.

Since the P2P_CONCURRENT_SEARCH_DELAY macro is not used anymore, the
driver specific build parameter for bcmdhd from Android.mk is also
removed. Similar configuration can now be achieved with
p2p_search_delay=0 in the p2p0 interface configuration file.

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.

5079392954 Increase buffer size and prevent write beyond buffer end
wpa_config_write_key_mgmt has a buffer size of 50. This is not enough
to fit the longest case. I used a network with "WPA-PSK WPA-EAP
WPA-NONE" and CONFIG_IEEE80211R=y + CONFIG_IEEE80211W=y to produce
a string longer than 50 chars. Increase the buffer size to 100 to
prevent truncated output.

Truncated output is not the only problem. If the buffer end is
reached when adding certain key mgmt types the function does not
return immediately. This leaves pos > end. When a second os_sprintf
is called the calculation of end - pos yields a large positive
number for buffer size. End result is a write beyond the buffer end.
Fix this by bailing out if buffer end is reached.

ctrl_interface parameter can be used to initiate some control interface
backends, so simpler designs were not available for this.

The format of the new parameter is not exactly cleanest due to
configuration file parsing assumptions. For example:

ctrl_interface=....
no_ctrl_interface=

would end up with ctrl_interface=NULL.
