The error reply needs to be sent out as a response. The "out" label was
in incorrect place to allow that to happen; instead, it ended up leaking
memory for the generated reply message.

The supplicant code does not try to control the actual channel of the
radio at any point. It simply passes the target peer and channel

periodically initiate TDLS channel-switch operations when TDLS
channel-switching is enabled.

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.
Signed-off-by: Jouni Malinen <j@w1.fi>
Start of station-mode WPS PBC/PIN/Registrar/NFC operation would result
in the AP mode getting disabled. This can be particularly confusing for
the P2P GO case where the group would need to be stopped cleanly. As
such, it is better to reject these invalid operations rather than trying
to handle all corner cases needed to allow this to work robustly.

There is no need to limit this property based on the role of the device

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.

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.

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).

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).
