Previously, any network block could be used to select the BSS to connect
to when processing scan results after Interworking network selection.
This can result in somewhat unexpected network selection in cases where
credential preferences indicated that a specific network was selected,
but another network ended up getting used for the connection. While the
older networks continue to be valid, add special processing for this
initial post-interworking-connect case to get more consistent network
selection to match with the Interworking network selection result.

Previously, network added event was skipping during group formation.
However, this did not necessarily catch all cases of temporary P2P
network blocks. Check ssid->p2p_group to make this behavior more
consistent by avoiding all P2P groups.

Add "StaAuthorized" and "StaDeauthorized" D-Bus interface in AP mode.
After enabling the AP mode of wpa_supplicant, the other process need to
get the MAC address and authorization status of every station, so
wpa_supplicant emits signal when the station is authorized or
deauthorized.

In the properties changed signal, added a new property
"DisconnectReason", which carries the IEEE 802.11 reason code of the
most recent disassociation or deauthentication event. The reason code is
negative if it is locally generated. The property is sent to the DBUS
immediately so as to prevent it from being coalesced with other
disconnect events.

Send an "EAP" signal via the new DBus interface under various
conditions during EAP authentication:
- During method selection (ACK and NAK)
- During certificate verification
- While sending and receiving TLS alert messages
- EAP success and failure messages
This provides DBus callers a number of new tools:
- The ability to probe an AP for available EAP methods
(given an identity).
- The ability to identify why the remote certificate was
not verified.
- The ability to identify why the remote peer refused
a TLS connection.

Some applications require knowing about probe requests to identify
devices. This can be the case in AP mode to see the devices before they
connect, or even in P2P mode when operating as a P2P device to identify
non-P2P peers (P2P peers are identified via PeerFound signals).
As there are typically a lot of probe requests, require that an
interested application subscribes to this signal so the bus isn't always
flooded with these notifications. The notifications in DBus are then
unicast only to that application.
A small test script is also included.

Add a new persistent group network block field, p2p_client_list, to
maintain a list of P2P Clients that have connected to a persistent
group. This allows GO of a persistent group to figure out more easily
whether re-invocation of a persistent group can be used with a specific
peer device.

The GO negotiation response is very cryptic at the moment. For a success
message we only know on which interface the negotiation succeeded, not
which peer. For a failure we know the interface also and a status code
(number).
It will be very useful for clients to know upon receipt of such a message
which peer the negotiation occurred with.
Now that the peer information is available and the API is changed
already, the function composing the D-Bus message might as well include
all GO negotiation information. This is done with a dict to make things
easier on clients if this result information changes down the line.

If a P2P group network block is removed for any reason (e.g., wps_cancel
command) while the interface is in group formation, remove the group
formation timeout and indicate failure immediately. Previously, this
type of operations could end up leaving the timeout running and result
in somewhat unexpected group formation failure events later.

Add a D-Bus signal for EAP SM requests. This signal is emitted on the
Interface object so that clients only have to listen to one object for
requests rather than to all network objects. This signal is analogous
to the socket control interface's CTRL-REQ- request.

If a network configuration block is removed or modified, flush
all PMKSA cache entries that were created using that network
configuration. Similarly, invalidate EAP state (fast re-auth).
The special case for OKC on wpa_supplicant reconfiguration
(network_ctx pointer change) is now addressed as part of the
PMKSA cache flushing, so it does not need a separate mechanism
for clearing the network_ctx values in the PMKSA cache.
In general, this patch attemps to extend commit
00468b4650 with dbus support.
This can be used by dbus client to implement subject match text
entry with preset value probed from server. This preset value, if
user accepts it, is remembered and passed to subject_match config

Extend commit c2762e410f to allow
applications to manage (add/remove) persistent groups and accepted
network object paths while invoking a persistent group.
Do not emit network objects during P2P group formation since such
network objects can confuse certain apps. Instead, a persistent group
object is created to allow apps to keep track of persistent groups.
Persistent group objects only represent the info needed to recreate the
group.
Also fixes a minor bug in the handling of persistent group objects
during WPS operations.

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.
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.
Expose RSN and WPA properties for BSS objects containing information
about key management and cipher suites. Get rid of WPA/RSN/WPSIE
byte array properties and add IEs byte array property with all IE data
instead.
The actual supplicant state is exposed via a property on the interface
object. So having a separate signal StateChanged for notifying about
changes is a bad idea. The standard PropertiesChanged signal should be
used for this.
The advantage of StateChanged signal was that it includes the previous
state, but not even NetworkManager is making use of this. And tracking
the old state via the property and this signal is easily possible anyway.
This callback structure was specific to the new D-Bus API which makes
it more or less pointless. It is just simpler to call the notification
functions directly. More proper design could be to use a generic
mechanism for registering notification callbacks into notify.c, but
that is not yet available and should not be designed just based on a
single user.
This was mostly identical code that had been copied for the new D-Bus
API implementation and as such, should really have been shared from
the beginning. In addition, the copied code ended up generating
interesting stack traces since the actual D-Bus connection was being
shared even though the pointer to it was stored in two distinct
data structures. The old D-Bus code ended up dispatching some
D-Bus callbacks which ended up running the new D-Bus code.
Since the private context pointers were mostly identical, everything
seemed to more or less work, but this design was just making things
more complex and potentially very easy to break.
Replace the scan results -based implementation with the use of information
from the new BSS table maintained by wpa_supplicant to get a more stable
source of BSS data. Change the use of BSSID as the key for the BSS object
to use the BSS table unique identifier so that multi-SSID APs can be
handled properly.
Initialize the new DBus API before the old one, so new applications
which can use both, the old and the new API will be notified first
that new API is available.
This patch implements the new DBus API. Both, the new and the
previous API may work concurrently and may be turned on or off
separately in .config file.
Some features of the new API are:
- more wpa_supplicant's events are signaled with DBus signals,
- introspection data (requires libxml2 and may be disabled),
- CurrentBSS and CurrentNetwork properties,
- PropertyChanged signal for most of properties,
- Relatively easy to extend.
.config options for the new API are: CONFIG_CTRL_IFACE_DBUS_NEW=y and
CONFIG_CTRL_IFACE_DBUS_INTRO=y for introspection.
This commit misses couple of parts from the full implementation
(these are still under review):
- fetching all configuration parameters for learning WPS information
- scan result BSS add/remove notification (register_bss() and
unregister_bss() notification callbacks)
This patch completely separates supplicant's code from dbus.
It introduces three new notifications which copes with all
remaining dbus stuff.
wpas_notify_unregister_interface() was renamed to
wpas_notify_iface_removed().
This introduces a new mechanism for collecting notification calls into
a single place (notify.c). As a result of this, most of the
wpa_supplicant code does not need to know about dbus (etc. mechanisms
that could use the notifications). Some empty placeholder functions are
also added in preparation of new dbus code that needs more event
notifications.
