ed57c5907e SME: Fix processing of Authentication request failure
The wpa_state needs to be dropped back to DISCONNECTED to allow scan
results to trigger a new authentication attempt. In addition, we can use
wpas_connection_failed() instead of requesting a scan after a fixed time
to make this error case more consistent with other similar error paths
in sme.c.

f98eb880eb Update RSN supplicant MAC address on driver reinitialization
I have a test case where I remove and insert another network adapter
between two connections to AP. The interface get the same interface name
but switches macadresses between the connections. When running WPA2 I
got a failure in EAPOL negotiation and found out that the reason for
this was that the supplicant did not update the MAC address in the
correct place.

c0f83f3104 WPS: Disable WPS(v2) in WPA/TKIP-only configuration
When using wpa_supplicant AP mode, WPS support is enabled by default for
WPA/WPA2-Personal. Change this to enforce the WPS2 rules on not allowing
WPS to be used with WPA/TKIP-only configuration (i.e., at minimum, mixed
mode with WPA/TKIP and WPA2/CCMP has to be used for WPS to be enabled).

56d24b4ee0 Call wpas_connection_failed() only if actually trying to connect
A disconnection event from the driver may end up getting delivered at a
time when wpa_supplicant is not even trying to connect (e.g., during a
scan that was already started after WPS provisioning step). In such a
case, there is not much point calling wpas_connection_failed() and
skipping this avoids confusing attempts of re-starting scanning while
the previous scan is still in progress.

a9e02d593d P2P: Clear show_group_started on GO start
The show_group_started variable could be left to 1 based on an earlier
failed attempt to start P2P client operation. This can result in
unexpected P2P-GROUP-STARTED event when a GO is started without group
formation (e.g., re-invoke a persistent group or start an autonomous
GO). Avoid this by explicitly clearing show_group_start when setting up

ea5bae4731 Increase min sched_scan interval from 2 to 10 seconds

ef992bbd3b wpa_gui-qt4: Improve scan results signal display
Display signal strength in dBm with visual indicator in the form of a
bar for scan results displayed by wpa_gui-qt4. Any signal > -35dBm is
treated as full signal bar, signals between range of -95<->-35dBm are
displayed linearly. Convert WEXT signal level value to scale that
nl80211 typically reports in dBm. The condition which differentiates
8-bit WEXT dBm and regular dBm is probably fragile, but there is
currently no way to know what the driver is going to report for signal
strength.

a9022616ae dbus: Implement EAP SM control request signals
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.

9ef1aaae24 Use an enum for EAP SM requests
Control requests will be extended for non-EAP uses later, so it makes
sense to have them be generic. Furthermore, having them defined as an
enum is easier for processing internally, and more generic for control
interfaces that may not use field names. The public ctrl_req_type /
field_name conversion function will be used later by the D-Bus control
interface too.

The interface may not yet have been set to P2P client mode immediately

97bcd562eb Remove disable_11b_rates() driver_ops
This function was used unconditionally if wpa_supplicant build
includes CONFIG_P2P=y. Adding a separate driver_ops for such use
is not really useful since the driver wrappers can do the same
internally. Remove this driver_ops and move matching functionality
into driver_nl80211.c which was the only driver wrapper using
this driver_ops callback.

4483f23e15 dbus: Raise PropertiesChanged on org.freedesktop.DBus.Properties
wpa_supplicant dbus objects are currently difficult to use with
GDBusProxy. This is because they do not follow the dbus standard in
emitting the PropertiesChanged signal on the standard D-Bus properties
interface, so GDBusProxy stores stale property values.

Fix this by raising PropertiesChanged on the standard interface.
For backwards compatibility, the existing custom PropertiesChanged
signals are not removed; I anticipate them being removed in a future
major release.

2d4f15d683 P2P: Stop any on-going "p2p_find" on creating an Autonomous GO
This patch stops any on-going "p2p_find" on creating an Autonomous GO.
This is already taken care in case of invoking a persistent GO. GO as
such will be advertising via the beacons for other devices to discover.
So normally the GO doesn't need to do a p2p_find until and unless it
wants to invite a P2P Client. In case of Invite scenario, logically it
is better to do a explicit discover [via user intervention] after the GO
is created. This patch will help to reduce battery wastage [due to
p2p_find operations] in scenarios where user creates a GO and doesn't
initiate a connection.
