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.

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

f1a5263389 Maintain maximum blacklist count over list clear operations
wpas_connection_failed() uses the blacklist count to figure out a
suitable time to wait for the next scan. This mechanism did not work
properly in cases where the temporary blacklist gets cleared due to no
other BSSes being available. Address this by maintaining an additional
count of blacklisting values over wpa_blacklist_clear() calls. In
addition, add one more step in the count to timeout mapping to go to 10
second interval if more than four failures are seen.

45ac5793fc new_dbus_handlers: Clear errno
There are a few instances where dbus handlers test the value
of errno to test whether strtoul completes successfully.
Since strtoul does not clear errno, and there's no strong
reason to suspect that errno is already clear, it is safer
to clear it right before calling strtoul.  Also, any failure
in strtoul (setting errno non-zero) should be considered a
failure.

While testing using dbus-send, I found that a malformed
network path can cause a crash due to net_id being left
NULL.  We should test for this before calling strtoul
on it.

Tested with:

dbus-send --system --dest=fi.w1.wpa_supplicant1 --print-reply \
    /fi/w1/wpa_supplicant1/Interfaces/0 \
    org.freedesktop.DBus.Properties.Get \

Like bgscan, autoscan is an optional module based feature to automate
scanning but while disconnected or inactive.

Instead of requesting directly a scan, it only sets the scan_interval
and the sched_scan_interval. So, if the driver supports sched_scan,
autoscan will be able to tweak its interval. Otherwise, the tweaked
scan_interval will be used. If scan parameters needs to be tweaked, an
autoscan_params pointer in wpa_s will provide those. So req_scan /
req_sched_scan will not set the scan parameters as they usually do, but
instead will use this pointer.

Modules will not have to request a scan directly, like bgscan does.
Instead, it will need to return the interval it wants after each
notification.

As there are typically a lot of probe requests, require that an

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.

6fc74e5181 dbus: Increase buffer size to fix Introspect XML
Commit e9c3c1afed added a new D-Bus
method and that was enough to push the Introspect XML buffer over
the previously allocated 8000 bytes. Increase the buffer size to
make enough room for P2P interface. In addition, add a debug
message to indicate if an XML segment does not fit into the buffer
to make this types of failures somewhat easier to catch.

b3bcc0f519 P2P: Replace p2p_get_peer_info with p2p_peer_known when applicable
p2p_get_peer_info() was used in multiple places just to check whether a
specific peer is known. This was not the designed use for the function,
so introduce a simpler function for that purpose to make it obvious that
the p2p_get_peer_info() function is actually used only in ctrl_iface.c.

19030351b9 wpa_supplicant/dbus AP: Add support for WPS Internal Registrar
When in AP mode, wpa_supplicant is now enabling WPS (only Internal
Registrar). WPS.Start() call can be used to initiate WPS negotiation
similarly to how this is done in station mode.

This was done to ctrl_iface by Jouni Malinen on April 21, 2009 (commit
3ec97afe57)

e5a359cf7e P2P: Make GO negotiation peer and group information available over D-Bus
The GO negotiation response is very cryptic at the moment. For a success
message we only know on which interface the negotiation succeeded, not
which peer. For a failure we know the interface also and a status code
(number).

It will be very useful for clients to know upon receipt of such a message
which peer the negotiation occurred with.

Now that the peer information is available and the API is changed
already, the function composing the D-Bus message might as well include
all GO negotiation information. This is done with a dict to make things
easier on clients if this result information changes down the line.

7165c5dc1f P2P: Fix 32-bit compiler warnings on service discovery reference
Convert core wpa_supplicant code to use u64 instead of void * for the
P2P service discovery reference. Use uintptr_t in type casts in
p2p_supplicant.c to handle the conversion without warnings.

Note: This needs to be revisited for 128-bit CPU where sizeof(void *)
could be larger than sizeof(u64).

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.

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

The default discovery type is to search for devices only on social
channels. Expand this to also support an initial full scan followed by the
scan of social channels as well as the progressive scan that scans through
all the channels in the Search state rounds. This does not change the
default of scanning only social channels although there is currently a
discrepancy wrt the default used by wpa_cli, which is the full scan first.

af9d709019 D-Bus: Fix memory leak when using array of array of bytes
When parsing a dict entry which is an array of an array of bytes the entry
representing the dict entry has DBUS_TYPE_ARRAY as its type and
WPAS_DBUS_TYPE_ARRAY as its array_type. The function freeing this parsed
data incorrectly tested the entry type for WPAS_DBUS_TYPE_ARRAY while doing
no testing of this value for array_type. This results in a memory leak
whenever a D-Bus message with this type of data is parsed.

Messages affected are:
fi.w1.wpa_supplicant1.Interface.P2PDevice
	using RequestedDeviceTypes with Find method
	using SecondaryDeviceTypes or VendorExtension with P2PDeviceProperties

fi.w1.wpa_supplicant1.Group
	using WPSVendorExtensions with Properties property

All of the above messages are parsed with the same function,
wpa_dbus_dict_get_entry, so the assignment of the entry's type and
array_type is consistent. The parsed data is also consistently freed with
the same function, wpa_dbus_dict_entry_clear, so we can use the same checks
to free the data correctly.

07fecd3915 P2P: Remove Label config method
The P2P specification (3.1.4.3) disallows use of the Label configuration
method between two P2P devices. This was previously enforced at upper
level, but the obsolete code can be removed from wpa_supplicant. This
adds a bit more strict enforcement of the policy, but should not result
in practical differences since no known P2P implementation uses Label
config method.

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.
