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.

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.

See
http://lists.freedesktop.org/archives/dbus/2011-August/014593.html
for more info.

97a8cbb88d D-Bus/P2P: Treat PIN as string
wpa_supplicant returns the PIN in reply to the connect method. Treating
this value as an integer runs the risk of not returning the correct
value if the first digit(s) happens to be a zero(es). To return the
correct PIN it needs to be returned as a string.

3320666494 dbus: Remove separate access variable from properties
The read, write, read-write permissions can be figured out from
getter/setter function pointers, so there is no need for maintaining
that information separately.

6aeeb6fa21 dbus: clean up new D-Bus interface getters and setters
A number of fixes/improvements here:

1) Remove casting of getter/setter function types which allows
us to change the prototypes in the future and not have hard-to-find
runtime segfaults

2) Instead of having the getters create a fake reply message which
then gets its arguments copied into the real reply message, and is
then disposed, just pass message iters around and have them add
their arguments to the message itself

3) For setters, just pass in the message iter positioned at the
start of the argument list, instead of each setter having to skip
over the standard interface+property name

4) Convert error handling to use DBusError and return the error
back down through the call stacks to the function that will
actually send the error back to the caller, instead of having a
fake DBusMessage of type DBUS_MESSAGE_TYPE_ERROR that then
needs to have the error extracted from it.

But most of all, this fixes various segfaults (like rh #725517
and #678625) which were caused by some functions deep down in the
getter callpaths wanting a source DBusMessage* when the getters were
used for two things: signals (which don't have a source DBusMessage)
and methods (which will have a source DBusMessage that's being
replied to).  This duality made the code fragile when handling
errors like invalid IEs over the air.

ade74830b4 Add dbus signal for information about server certification
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
for any future authentication.

c2762e410f P2P: Update D-Bus network object semantics during group formation
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.

2b65b30da8 dbus: Add D-Bus methods to flush the BSS cache
Add an "Interface.FlushBSS" method to the new D-Bus API and a "flush"
method to the old API. Both take an age parameter that is a threshold
(in seconds) for selecting entries to evict. Setting this parameter
to zero flushes all entries from the cache.

This mechanism is useful for a connection manager to clear state at
startup and on resume (where the age parameter may be used to hold
onto recent/valid data).

7cc5995845 Skip D-Bus signals if the dbus_path is not yet set
This avoids an invalid D-Bus call during interface initialization.
The wpa_state change can happen before the D-Bus interface is set up,
so we must be preparted to handle this early event signal. In theory,
it should be possible to reorder initialization code to make sure
D-Bus signals are ready, but that would likely require quite a bit of
code restructuring, so it looks like a safer option for now is to just
skip the early event.

abd7a4e353 dbus: Aggregate PropertiesChanged signals
Instead of sending PropertiesChanged signals for each changed
property separately, mark properties as changed and send aggregated
PropertiesChanged signals for each interface in each object.
Aggregated PropertiesChanged signal is sent
- for all object after responding on DBus call
- for specified object after manual call to
  wpa_dbus_flush_object_changed_properties() function
- for each object separately after short timeout (currently 5 ms)
  which starts when first property in object is marked changed

27f43d8de5 dbus: Replace StateChanged with PropertiesChanged signal
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.

e90bd80cf5 dbus: Remove duplication of object methods/signals/properties
There is no need to duplicate the method/signal/property arrays that
were registered for objects. The registration was using static arrays
on methods/signals/properties in all places and we can as well use
those throughout without having to allocate memory and copy all the
entries for every object. This reduces number of allocations and
amount of unnecessary code quite a bit.

52bdd880a3 dbus: Remove wpas_dbus_callbacks abstraction
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

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.

8ddef94bd4 dbus: Share common initialization code for both old and new interface
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.
