376204934d wpa_cli: Support tab completion with ifname= prefix
Enable tab completion for the cases where ifname= prefix is used in
interactive mode by skipping over that prefix before running through the
per-command completion routines. The ifname= prefix itself is also
covered by adding the possible interface names to the command list.

13b11ba702 wpa_cli: Allow IFNAME= prefix to be used
Strip out the IFNAME=<ifname> prefix from commands before parsing them
through the normal processing and then add the prefix back to the
beginning of the actual control interface command to make per-interface
commands work through the global control interface without having to use
the 'raw' command.

b06800170a Fix already-associated detection with driver-based BSS selection
wpa_s->pending_bssid is all zeros during connection attempt when
driver-based BSS selection is used. Take this into account when
determining whether new scan results should trigger a connection based
on wpa_s->current_ssid, i.e., a connection attempt with the selected
network instead of selected BSS.

9e1ecab1c5 GAS: Ignore replays if previous frag_id without dropping GAS session
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.

fa7ae9501b Add test code for fetching the last configured GTK
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".

576bce9c86 P2P: Direct global ctrl_iface commands automatically for P2P
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.

d7692b8d1c dbus: Terminate cleanly on messagebus shutdown
By default, dbus_connection_dispatch() will call _exit() if the bus
connection has been closed. This caused wpa_supplicant to terminate

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.

0cdb93fe9f Do not add BSS to blacklist on local disconnection request
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).
