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

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.

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.

Android framework maintains a state to process the scan results after

It is possible for scan result processing or BSS entry removal to occur
while there is a pending connect or sme-connect radio work with a
previously selected BSS entry. The BSS pointer was previously verified
to be valid, i.e., still point to a BSS entry, at the time the actual
connection operation is started. However, that BSS entry could have
changed to point to another BSS if the old BSS entry was either removed
or reallocated and a new BSS entry was added at the same location in
memory. This could result in the connection attempt failing to configure
parameters properly due to different BSS information (e.g., different
BSSID).
Fix this by updated the pending connect radio work data on BSS entry
updates similarly to how the last_scan_res array was updated. If the
selected BSS entry is removed, this will still result in a failed
connection, but reallocated BSS entry is now followed properly and used
when the connection work starts.

mechanism for adding vendor elements into frames") has a minor bug
where it miscalculates the length of memory to move using
os_memmove. If multiple vendor elements are specified then this can
lead to out of bounds memory accesses.
This patch fixes this by calculating the correct length of remaining
data to shift down in the information element.

Use hostapd_freq_params instead of simple frequency parameter for driver
commands. This is preparation for IBSS configuration to allow use of
HT/VHT in IBSS.

Previously, the case of non-netdev P2P management device ended up
pulling in both the main interface (e.g., wlan0) and P2P Device
interface (from command line -m argument) as configuration. Similarly,
the main interface ended up included both configuration files. This is
not really helpful for various use cases, e.g., when permanent P2P group
information is stored in the P2P Devince interface, but it gets
duplicated in the main station interface configuration.
Clean this up by changing the -m<file> argument to replace, not
concatenate, configuration information. In other words, the main station
interface will not read this configuration and the P2P Device interface
(non-netdev) does not read parameters from the station interface
configuration file.
