4b07280319 auto-t: fix wait_for_object_condition to work with any object
After recent changes fixing wait_for_object_condition it was accidentally
made to only work with classes, not other types of objects. Instead
create a minimal class to hold _wait_timed_out so it doesnt rely on
'obj' holding the boolean.

c026337792 station: move scan cancelation to __station_connect_network
An earlier patch fixed a problem where a queued quick scan would
be triggered and fail once already connected, resulting in a state
transition from connected --> autoconnect_full. This fixed the
Connect() path but this could also happen via autoconnect. Starting
from a connected state, the sequence goes:

 - DBus scan is triggered
 - AP disconnects IWD
 - State transition from disconnected --> autoconnect_quick
 - Queue quick scan
 - DBus scan results come in and used to autoconnect
 - A connect work item is inserted ahead of all others, transition
   from autoconnect_quick --> connecting.
 - Connect completes, transition from connecting --> connected
 - Quick scan can finally get triggered, which the kernel fails to
   do since IWD is connected, transition from connected -->
   autoconnect_full.

This can be fixed by checking for a pending quick scan in the
autoconnect path.

0c277e442e station: Remove unneeded logic from dbus_scan_done
Commit eac2410c83 ("station: Take scanned frequencies into account")
has made it unnecessary to explicitly invoke station_set_scan_results
with the expire to true in case a dbus scan finished prematurely or a
subset was not able to be started.  Remove this no-longer needed logic.

5370fefdad client: update to work with diagnostic changes
The diagnostic interface will now only come up when station is
connected. This avoids the need for display station to return
a 'connected' out parameter. We can instead just see that
the diagnostic interface doesn't exist.

c3e160880f station: only add diagnostic interface when connected
The diagnostic interface returns an error anyways if station is
not connected so it makes more sense to only bring the interface
up when its actually usable. This also removes the interface
when station disconnects, which was never done before (the
interface stayed up indefinitely due to a forgotten remove call).

6ced1ec9de station: Use active scan in autoconnect mode
When we're auto-connecting and have hidden networks configured, use
active scans regardless of whether we see any hidden BSSes in our
existing scan results.

This allows us to more effectively see/connect to hidden networks
when first powering up or after suspend.

9af25d937d station: Make sure bss_match also matches the ssid
Kernel might report hidden BSSes that are reported from beacon frames
separately than ones reported due to probe responses.  This may confuse
the station network collation logic since the scan_bss generated by the
probe response might be removed erroneously when processing the scan_bss
that was generated due to a beacon.

Make sure that bss_match also takes the SSID into account and only
matches scan_bss structures that have the same BSSID and SSID contents.

676ee1e4d2 ap: tie diagnostic interface to AP Start/Stop

2bebb4bdc7 netdev: Handle deauth frames prior to association
In some cases the AP can send a deauthenticate frame right after
accepting our authentication.  In this case the kernel never properly
sends a CMD_CONNECT event with a failure, even though CMD_COONNECT was
used to initiate the connection.  Try to work around that by detecting
that a Deauthenticate event arrives prior to any Associte or Connect
events and handle this case as a connect failure.

d372d59bea station: Allow ConnectHiddenNetwork to be retried
In the case that ConnectHiddenNetwork scans successfully, but fails for
some other reason, the network object is left in the scan results until
it expires.  This will prevent subsequent attempts to use
ConnectHiddenNetwork with a .NotHidden error.  Fix that by checking
whether a found network is hidden, and if so, allow the request to
proceed.

756158dfc9 knownnetworks: sanitize known_network.freq on load
An invalid known_network.freq file containing several UUID
groups which have the same 'name' key results in memory leaks
in IWD. This is because the file is loaded and the group's
are iterated without detecting duplicates. This leads to the
same network_info's known_frequencies being set/overridden
multiple times.

To fix this we just check if the network_info already has a
UUID set. If so remove the stale entry.

There may be other old, invalid, or stale entries from previous
versions of IWD, or a user misconfiguring the file. These will
now also be removed during load.

ed0f3e87ca netdev: Fix re-entrancy bug in netdev_shutdown
netdev_shutdown calls queue_destroy on the netdev_list, which in turn
calls netdev_free.  netdev_free invokes the watches to notify them about
the netdev being removed.  Those clients, or anything downstream can
still invoke netdev_find.  Unfortunately queue_destroy is not re-entrant
safe, so netdev_find might return stale data.  Fix that by using
l_queue_peek_head / l_queue_pop_head instead.
