4bdd556886 WPS: Fix MAC Address inside Credential be that of Enrollee's
The WPS 1.0h specification is quite unclear on what exactly should be
used as the MAC Address value in the Credential and AP Settings. It
looks like this should after all be the MAC Address of the Enrollee,
so change Registrar implementation to use that address instead of the
AP BSSID.

In addition, add validation code to the Enrollee implementation to
check the MAC Address value inside Credential (and also inside AP Settings)
to make sure it matches with the Enrollee's own address. However, since
there are deployed implementations that do not follow this interpretation
of the spec, only show the mismatch in debug information to avoid breaking
interoperability with existing devices.

3fd2a226f9 wpa_supplicant: Fix ctrl_interface group permissions to allow read/execute
When using umask 0077, the control interface directory was left without
group read/execute permissions even if the configuration file explicitly
asked for the group to be allowed to access the control interface. Fix
this by adding read/execute permissions for group if a specific group is
defined in the configuration. [Bug 199]

bd4ce06629 dbus: Allow only root to receive signals
Change the dbus policy file to only allow root applications to receive
signals from wpa_supplicant. This keeps WPS Credentials data secret
from non-root listeners.

1545457e04 wpa_gui-qt4: Fix build with Session Manager disabled in Qt4
When trying to build wpa_gui (Qt4 version) from openembedded it fails
because Qt4 is compiled without session manager and thus wpa_gui fails
to compile.

I attached a patch, that enables compiling without Session Manager (via
preprocessor) if it is not compiled into Qt4; otherwise, it behaves as
it does right now.

I checked to build on my host (Debian unstable, Session Manager
enabled) and openembedded (Session Manager disabled).

fcac668faa WPS: Use a dummy WSC_ACK as WLANEvent as the initial event if needed
UPnP device architecture specification requires all evented variables to
be included in the initial event message after subscription. Since this
can happen before we have seen any events, generated a dummy event
(WSC_ACK with all-zeros nonces) if needed.

00785aba71 WPS: Remove unused WFA WLANConfig Service actions
This removes following WFA WLANConfig Service actions and the related
state variables: GetAPSettings, SetAPSettings, DelAPSettings,
GetSTASettings, SetSTASettings, DelSTASettings, RebootAP,
ResetAP, RebootSTA, ResetSTA.

While WFA WLANConfig Service version 1.0 claims that some of these are
mandatory to implement for an AP, there are no known implementations
supporting these actions neither in an AP/proxy or an External Registrar
that would use them. These are unlikely to be supported in the future
either and as such, it is just simpler to get rid of them to clean up
the implementation and reduce code size.

d7199342f0 Reset EAPOL pointer when handling DBus smartcard parameters
Smartcard parameter update via DBus ended up re-initializing the EAPOL
state machine without updating the pointer inside WPA state machine.
This can trigger a segfault when EAP layer attempts to use the old
reference. Fix this by re-initializing the pointer inside WPA state
machine.

355d36a7bf Disassociate STA if it associated with invalid/missing WPA/RSN IE
When using drivers that process management frames internally (e.g.,
madwifi, atheros, bsd), the driver may accept association with IEs
that do not match the security policy. Instead of silently leaving
the station associated, explicitly disassociate it to clear the
driver entry immediately.

5be45e2e6e Fix per-SSID scan (scan_ssid=1)
Commit d3a9822542 broke per-SSID scan
by using the ssid variable for internal loop and by doing so,
overriding the value that was needed below to figure out whether the
scan is for a specific SSID. Fix this by using a temporary variable
instead when looping over network finding which frequencies to scan for.
