Add mechanism for using GAS/ANQP to query Interworking related
information from APs. The received information is stored in the BSS
table and can be viewed with ctrl_iface BSS command.
New ctrl_iface command ANQP_GET can be used to fetch ANQP elements from
a specific AP. Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be
used to initiate and stop an iteration through all APs in the BSS table
that indicate support Interworking to fetch ANQP elements from them.
It is now possible to configure the the time in seconds that
wpa_supplicant waits before requesting a new scan after failing to find
a suitable network in scan results.

Replace compile-time BSS cache expiration age and scan count by config
parameters that can be set via wpa_cli and the new D-Bus API. The latter
is done with interface properties BSSExpireAge and BSSExpireCount.
Some of the wpa_supplicant control interface commands, like WPS_PIN,
may not include a newline in the end of the response. This can result
in the response being lost when wpa_cli redraws the screen after an
event message. Add a newline after such responses in interactive mode
to avoid the problem.
CONFIG_WPA_CLI_EDIT=y can now be used to build wpa_cli with internal
implementation of line editing and history support. This can be used
as a replacement for CONFIG_READLINE=y.
Instead of using a separate process to receive and print event
messages, use a single-process design with eloop to simply
wpa_cli and interaction with readline.
Instead of multiple #ifdef blocks for readline within the function,
use two copies of the functions, one for readline, one without any
readline functionality.
Replacing the BSSID with 'any' has never worked with wps_reg
command, so better not claim it could work. In addition, reject
this is wpa_supplicant to make it clearer that the operation
fails.
This command can be used to enroll a network based on a local
network configuration block instead of having to (re-)learn the
current AP settings with wps_er_learn.
ctrl_interface STA_AUTOCONNECT command can now be used to disable
automatic reconnection on receiving disconnection event. The default
behavior is for wpa_supplicant to try to reconnect automatically, i.e.,
to maintain previous behavior.
A new ctrl_interface command, WPS_CANCEL, can now be used to cancel
a pending or ongoing WPS operation. For now, this is only available
with wpa_supplicant (either in station or AP mode). Similar
functionality should be added for hostapd, too.
If enabled, cross connection allows GO to forward IPv4 packets
using masquerading NAT from the P2P clients in the group to an
uplink WLAN connection. This is disabled by default and can be
enabled with "wpa_cli p2p_set cross_connect 1" on the P2P device
interface.
Advertize list of authorized enrollee MAC addresses in Beacon and
Probe Response frames and use these when selecting the AP. In order
to provide the list, the enrollee MAC address should be specified
whenever adding a new PIN. In addition, add UUID-R into
SetSelectedRegistrar action to make it potentially easier for an AP
to figure out which ER sent the action should there be multiple ERs
using the same IP address.
wps_er_config can now be used to configure an AP. It is similar to
wps_er_learn, but instead of only learning the current AP settings,
it continues to send M8 with the new settings for the AP.
wps_er_start command now takes an optional parameter that can be used
to configure a filter to only allow UPnP SSDP messages from the
specified IP address. In practice, this limits the WPS ER operations
to a single AP and filters out all other devices in the network.
'wpa_cli roam <bssid>' can now be used to test roaming within an ESS
(e.g., for FT over-the-air). This command will bypass a new scan and
will select the BSS based on the specified BSSID. It is responsibility
of the caller to make sure that the target AP is in the BSS table.
This can be done, e.g., by running a scan before the roam command,
if needed.
Need to kill the monitor process before running detach command on
the monitor connection to avoid race where the monitor process may
end up getting the detach command result.
wpa_supplicant can now be notified of suspend/resume events, e.g.,
from pm-action scripts. This allows wpa_supplicant to clear information
that may become invalid during a suspend operation.
CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config can be used to
configure wpa_cli build to make a version of wpa_cli that forks
a child process to receive event messages. This allows the events
to be shown immediately instead of having to wait for the next
periodic poll with PING.
