4aa9c156e5 dbus: Close dbus dict just after appending data
Before fixing this issue, calling wpas_dbus_getter_p2p_device_config
was causing early termination of dbus connection, due to writing
values to an already closed dict.

010fc5f507 dbus: Clean up array-array-type property getter
The previously used design was a bit too complex for static analyzers
(e.g., CID 68131, CID 68133) to understand which resulted in false
warnings about uninitialized memory. Avoid this by explicitly
initializing the pointer array to NULL and also skipping any invalid
NULL entry in the helper function.

1851e17a64 dbus: Clean up P2P group vendor ext getter
The vendor_ext[i] = NULL setting did not make any sense since
num_vendor_ext should have been used to index the vendor_ext array. The
old code did not do any harm since i >= num_vendor_ext and none of the
already set entries could have been cleared. Anyway, better clean this
by making it skip the setting to NULL similarly to what was already done
in the P2P peer vendor ext getter.

d3b204694a P2P: Make the default p2p_find delay value configurable
This makes the p2p_find default delay value configurable as
p2p_search_delay parameter through the configuration file (and through
control interface "SET p2p_search_delay <value>" on the P2P management
interface.

This parameter controls the number milliseconds of extra delay that is
added between search iterations when there is a concurrent operation in
progress. This can be used, e.g., p2p_search_delay=100 to make p2p_find
friendlier to concurrent operations by avoiding it from taking 100% of
the radio resources. The default value is the previous default, i.e.,
500 ms. Smaller values can be used to find peers more quickly at the
cost of larger effect to concurrent operations while a larger value
leaves more time for the concurrent operations at the cost of making
device discovery take longer time.

The optional p2p_find delay argument can still be used to override the
search delay for each search operation.

Since the P2P_CONCURRENT_SEARCH_DELAY macro is not used anymore, the
driver specific build parameter for bcmdhd from Android.mk is also
removed. Similar configuration can now be achieved with
p2p_search_delay=0 in the p2p0 interface configuration file.

bbc6c729a5 P2P: Use group formation timeout on persistent group GO
Previously, GO considered the group to be fully re-invoked after
starting beaconing on successful invitation exchange. This would leave
the group running until idle timeout (which may not be enabled) or
explicit removal if the client fails to connect for any reason. Since
the client is expected to connect immediately after the invitation
exchange that ends with status=0 (i.e., either client initiated the
exchange or it responded with success), extend group formation timeout
to cover that period until the first successfully completed data
connection. This allows the GO to remove the group automatically if the
client devices does not connect within
P2P_MAX_INITIAL_CONN_WAIT_GO_REINVOKE (15) seconds.

ca29842700 dbus: revert changes to some peer properties
Commit 3f6e50ac28 made it possible to access
P2P peer properties using the org.freedesktop.DBus.Properties interface.

While maintaining the original intent of that patch we make two changes
to it here:

First, 3f6e50ac28 changed the type used to
represent the WPS vendor extension data from bytes to a string. In
addition to the type change the way in which the vendor extension data
was provided to the function creating the string was incorrect and would
not present the correct vendor extension data even in string format.

Revert the type change made in 3f6e50ac28
and present the WPS vendor extension data as an array of an array of
bytes as it was before.

Second, 3f6e50ac28 changes the secondary
device types representation from an array of an array of bytes to an
array of bytes. Revert that change to make secondary device types
accessible via an array of an array of bytes again.

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.
