This makes the design more robust against unexpected duplicates since
each new GAS exchange gets a different dialog token compared to the
previous one.

It looks like it may be possible for an older GAS response to get retransmitted
even after the first copy has been processed. While this should not really come
up all the way to wpa_supplicant due to sequence number being same (i.e.,
duplicate detection should from the frame), some cases have been observed where
this did cause issues. Drop such a frame silently without dropping the ongoing
GAS session to allow a frame with the next frag_id to be processed after this.

This can be useful for some test cases, so allow wpa_supplicant to be
built with special test functionality to expose the current (last
configured) GTK. This is disabled by default and can be enabled by
adding following line into .config:
CFLAGS += -DCONFIG_TESTING_GET_GTK
The GTK can then be fetched with "wpa_cli get gtk".

The P2P management operations like P2P_FIND and P2P_CONNECT are not
really specific to any network interface. These are P2P Device level
operations that are in more global device context. Allow those to be
sent through the global control interface without IFNAME parameter.
For now, these commands are directed within wpa_supplicant to the
network interface that initialized the global P2P context. This may
change in the future if a special context is added for P2P operations.
Anyway, such changes can now be done internally within wpa_supplicant
without affecting this global control interface design from external
view point.

These events are sent as a special case to both the group interface and
"parent interface" (i.e., the interface that was used for managing P2P
negotiation). The latter is not really correct event, so get rid of it
with the new global control interface design where there is no need to
support legacy upper layer implementations.
Signed-hostap: Jouni Malinen <j@w1.fi>
This removes the "IFNAME=<ifname> " prefix from P2P events that are

Replace direct wpa_msg() calls with p2p_dbg(), p2p_info(), and p2p_err()

This removes wpa_ctrl.h dependency from src/p2p/* and makes the P2P
events more consistent, i.e., everything that is aimed for upper layer
processing from the wpa_supplicant control interfaces is generated in
p2p_supplicant.c.

This function can be used instead of wpa_msg() and wpa_msg_ctrl() to

The ATTACH/DETACH mechanism to request event messages from
wpa_supplicant can now be used through the global control interface,
too. This results in events from all interfaces being delivered through
a single monitor socket. "IFNAME=<ifname> " prefix is used on events
that are specific to an interface.

This is mostly a corner case at this point, but if wpa_cli was started

"IFNAME=<ifname> " prefix can now be used on the wpa_supplicant global

Commit 21d996f775 added p2p_pref_chan as a

By default, dbus_connection_dispatch() will call _exit() if the bus
connection has been closed. This caused wpa_supplicant to terminate
without properly cleaning up after itself.
To ensure that we terminate cleanly when the messagebus terminates,
override the exit_on_disconnect behavior and install a filter to handle
libdbus's "Disconnected" signal.

The WPS provisioning case does not result in successful connection by
design and as such, this can result in networks getting temporarily
disabled. Avoid this by clearing the failure counts on WPS success.

Instead of just adding the new network, prefer the network learnt from a
configuration token during the first connection attempt. This makes the
WPS NFC case behave similarly to the in-band provisioning cases if there
are more preferred networks in the scan results.

This cleans up debug log by not trying to process the disconnection
event as a failure that could result in blacklist addition and auto

This cleans up debug log by not requesting the auto connect on
dissassociation event if we are already in disconnected state and would

Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>
There is no point in marking a BSS temporarily blacklisted based on a
connection failure or disconnection case if that happens as a result of
a local request to disconnect. The blacklist entry could result on
unexpected BSS getting selected on the next connection attempt. In
addition, the code to try to find another BSS within the ESS could
result in scanning a single channel on the next attempt. Fix these
issues by handling the connection failure events only if we are not in
disconnected state (i.e., would try to reconnect after this
automatically).

The information of the peer's AID is required for the driver to

The Hotspot 2.0 specification seems to mandate this element to be
included in all (Re)Association Request frames if the station is Hotspot
2.0 capable. However, that results in conflicts with other requirements
like no TKIP use when this element is present. The design is really
supposed to include the indication element only for Hotspot 2.0
associations regardless of what the current specification implies.
Remove the HS 2.0 Indication element from (Re)Association Request frame
whenever the connection is not for Hotspot 2.0 purposes.
