c61bc23aa2 D-Bus: Fix byte array dict entry parser in out-of-memory case
entry->bytearray_value was left to point to freed memory in case
os_realloc_array() failed. This resulted in the following
wpa_dbus_dict_entry_clear() trying to free an already freed memory area.

d118a6b8c8 D-Bus: Fix WPS.Start method in AP/P2P GO mode
Previously, role="enrollee" was required to be used to allow the AP mode
WPS operation to be started. This is incorrect since the AP/GO will
operate in Registrar role. Fix this by ignoring the role parameter when
AP (including P2P GO) mode is enabled.

054dc3136f D-Bus: Clean up wpas_dbus_new_decompose_object_path()
None of the new D-Bus interface cases use the bssid_part in
decompose_object_path (while the old interface ones do). As such, this
is dead code and can be removed. In addition, the P2P addition here was
pretty ugly extension. Replace these with a cleaner way of passing the
separating string (e.g., "Networks") from the caller and returning the
requested item.

In addition, there is no need to allocate the returned item separately,
so use a single allocation and a pointer to that allocated memory. This
will make it easier for callers to have to free only a single
allocation. This is also fixing a memory leak in P2P invitation
persistent group case where the caller had missed the need to free the
returned values.

f11e797d4c D-Bus: Avoid valgrind warning due to compiler optimization
It looks like both gcc and clang optimize the (entry.type != foo ||
entry.array_type != bar) in a way that ends up evaluating the second
condition even when the first one results in 0. While this is not really
what the C language requirements on short-circuit evaluation require,
the compiler likely assumes this can have no side effects and with both
type and array_type being comparable in a single 64-bit operation, this
can clearly be a bit more efficient. While the code behaves same in both
cases, valgrind does warn about use of uninitialized memory when the
second condition is evaluated (entry.array_type is not initialized if
entry.type != DBUS_TYPE_ARRAY).

To keep valgrind logs cleaner, initialize entry.array_type to
DBUS_TYPE_INVALID so that these compiler optimizations do not result in
reading uninitialized memory.

19d4dab759 D-Bus: Avoid compiler warning on sometimes uninitialized variable
The logic in wpas_dbus_signal_p2p_provision_discovery() seemed to imply
that there could be a case where _signal would be used uninitized. While
that is not the case since either (request || !status) or (!request &&
status) would always be true, some compilers do not seem to be clever
enough to figure that out to avoid the warning. Make this easier for
such compilers by removing the (!request && status) condition since it
is identical to !(request || !status).

bc7baaff24 D-Bus: Make WPAS_DBUS_TYPE_BINARRAY value less confusing
Commit 911e97e400 ('DBus: Refactor array
adding, add binary arrays') introduced WPAS_DBUS_TYPE_BINARRAY as an
internal fake type for array_type. However, it selected this value to be
(DBUS_NUMBER_OF_TYPES + 100) = 116 = 't'. This happens to conflict with
DBUS_TYPE_UINT64 ((int) 't'). While none of the existing array_type use
cases supported UINT64, it is much clearer if WPAS_DBUS_TYPE_BINARRAY
has a value that does not match any existing DBUS_TYPE_* value. Replace
this with '@' (64).

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.

scan. Thus, take much less time for the client to re-establish

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
