c143c3b72a D-Bus: Add a dbus handler for expected disconnection
Add a global D-Bus handler ExpectDisconnect for setting
wpa_s->own_disconnect_req flag. This flag will prevent wpa_supplicant
from adding blacklists and requesting incomplete scan upon the incoming
disconnection. This is mainly meant for a case where suspend/resume is
used and some external component knows about that and can provide the
information to wpa_supplicant before the disconnection happens.

fd7d3c495e D-BUS: dev_passwd_id should be "q" because it uses DBUS_TYPE_UINT16
This corrects the type of dev_passwd_id in GONegotiationRequest event.
This field is packed as DBUS_TYPE_UINT16 but in

dfaf11d648 P2P: Require fresh scan results for persistent group re-invocation
The P2P group is not yet operating when going through invitation
exchange for re-invocation. Previously, an old cached scan result could
be used to skip the scan immediately after the invitation exchange.
While this may result in the fastest possible connection, it does have
some issues with cases where the GO takes some time to start up. It
would also be at least theoretically possible for some of the BSS
parameters to be different, so having a fresh scan result from the new
GO instance may be desired in any case.

Add a mechanism to skip scan results that have been last updated before
a specific point in time and as the first user for this mechanism,
require chan results to be more recent than the invitation message
exchange for the P2P Client role in persistent group re-invocation case.

1fbff0b5c4 D-Bus: Set last_scan_req to MANUAL_SCAN_REQ on Scan() trigger paths
The D-Bus Scan() handler was setting wpa_s->scan_req = MANUAL_SCAN_REQ
on the code path that used wpa_supplicant_req_scan(). However, it did
not do anything similar for the cases where
wpa_supplicant_trigger_scan() is called directly. This could result in
unexpected wpa_s->last_scan_req value and incorrect behavior especially
when using ap_scan=2 and running a scan while operating in AP mode. Fix
this by explicitly setting wpa_s->last_scan_req = MANUAL_SCAN_REQ when
using wpa_supplicant_trigger_scan() from the Scan() handler.

8a78e227df D-Bus: Fix operations when P2P management interface is used
Commit 21efc940f6 ('wpa_supplicant: Do not
register a P2P management interface on DBus') hides the special P2P
management interface from D-Bus. However, it did not take into account
the possibility of wpa_s->dbus_path and wpa_s->dbus_new_path being NULL
in such cases on number of code paths within the D-Bus handlers. This
could result in invalid arguments (NULL path) being provided to D-Bus
functions (mainly, dbus_message_iter_append_basic) and NULL pointer
dereference when iterating over all interfaces. Either of these could
make wpa_supplicant process terminate.

Fix this by explicitly checking that the interface-specific D-Bus path
has been registered before using it anywhere with D-Bus handlers. In
addition, find the correct wpa_s instance to fix P2P operations through
D-Bus when the P2P Device interface is used.

8e2c5f1a20 dbus: Fix WPS property of fi.w1.wpa_supplicant1.BSS interface
The dbus interface documentation says the following about the
WPS property of the fi.w1.wpa_supplicant1.BSS interface:

==
WPS information of the BSS. Empty dictionary indicates no WPS support.
Dictionary entries are:

Type	s	"pbc", "pin", ""
==

However the implementation returns "type" => "" for BSSes
that do not support WPS.

Fix the implementation to match the documentation.
Return empty dictionary if there is no WPS support.
And "type" => "" if WPS is supported, but is not in progress
right now.

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.

that there could be a case where _signal would be used uninitized. While
that is not the case since either (request || !status) or (!request &&

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

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).

beb9e1171e dbus: Avoid theoretical memory leaks with duplicated dict entries
If a dict would include duplicated items, the parsing code here would
have leaked memory by overwriting old os_strdup() result with the new
one. Fix this by explicitly freeing the previous entry. This addresses
CID 62852, CID 62851, CID 62850, CID 62849, CID 62847, CID 62846.

ceb4cd89c9 dbus: Fix a potential double-free in on error path (CID 62880)
It would have been at least theoretically possible to hit the first
error in the loop and end up jumping to error handling which would call
os_free(value) without the value having been cleared after the os_free()
call at the end of the previous loop iteration.

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.

0f44ec8eba Add a reattach command for fast reassociate-back-to-same-BSS
Add "reattach" command to perform single-channel single-ssid scan
instead of full scan when trying to reconnect to the currently
"connected" network (assuming old scan results are not current enough to
skip the scan completely). This allows the scan result to come back in
much faster time. In ath9k, the scan took around 12 seconds with full
background scan, and only 0.1 second with the single-channel single-ssid
scan. Thus, take much less time for the client to re-establish
connection with the currently "connected" network.

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.
