[PATCH v2 1/7] dbus: add helper for appending a dictionary
by James Prestwood
Arrays of dictionaries are quite common, and for basic
types this API makes things much more convenient by
putting all the enter/append/leave calls in one place.

[RFC 0/1] Diagnostic Interface
by James Prestwood
This interface would expose details are may be too low level for a
general purpose application, like a connection manager. Some of these
details are useful though and these will go into this new diagnostic
interface. This interface is also going to be very useful in the
autotesting framework.
The GetDiagnostics() method is somewhat mapped to GET_STATION in
nl80211. Some of these values are too volatile to express as properties
as they change frequently so an application may get them at the time
they are needed.
The additional properties would be purely for autotesting/debugging.

[PATCH] netdev: fix asymmetry in handshake events
by James Prestwood
A failed/timed out handshake can sometimes result in no
HANDSHAKE_EVENT_FAILED event. This is because if IWD receives
a deauth before the eapol timeout expires the handshake is
cleaned up without any error being signaled. This ends up being
ok because netdev has its own handshake failed event associated
with the connect attempt which station/others handle
appropriately.
The issue lies more with what a handshake event consumer would
expect. Not receiving a failed event in the case of a failure
is unexpected. Future changes will rely on symmetry of these
events so it is being fixed now.
This case can be detected inside the netdev death event handler
by checking if last_code was ever set. If last_code is zero,
and netdev is not operational we have hit this situation and
netdev needs to manually trigger HANDSHAKE_EVENT_FAILED.
