This documents new DBus property that expose a bit more control to
how IWD roams.
Setting the affinity on the connected BSS effectively "locks" IWD to
that BSS (except at critical RSSI levels, explained below). This can
be useful for clients that have access to more information about the
environment than IWD. For example, if a client is stationary there
is likely no point in trying to roam until it has moved elsewhere.
A new main.conf option would also be added:
[General].CriticalRoamThreshold
This would be the new roam threshold set if the currently connected
BSS is in the Affinities list. If the RSSI continues to drop below
this level IWD will still attempt to roam.
PKEX is part of the WFA EasyConnect specification and is
an additional boostrapping method (like QR codes) for
exchanging public keys between a configurator and enrollee.
PKEX operates over wifi and requires a key/code be exchanged
prior to the protocol. The key is used to encrypt the exchange
of the boostrapping information, then DPP authentication is
started immediately aftewards.
This can be useful for devices which don't have the ability to
scan a QR code, or even as a more convenient way to share
wireless credentials if the PSK is very secure (i.e. not a
human readable string).
PKEX would be used via the three DBus APIs on a new interface
SharedCodeDeviceProvisioning.
ConfigureEnrollee(a{sv}) will start a configurator with a
static shared code (optionally identifier) passed in as the
argument to this method.
StartEnrollee(a{sv}) will start a PKEX enrollee using a static
shared code (optionally identifier) passed as the argument to
the method.
StartConfigurator(o) will start a PKEX configurator and use the
agent specified by the path argument. The configurator will query
the agent for a specific code when an enrollee sends the initial
exchange message.
After the PKEX protocol is finished, DPP bootstrapping keys have
been exchanged and DPP Authentication will start, followed by
configuration.
Add an additional optional PairwiseCipher property on
net.connman.iwd.StationDiagnostic interface that will hold the current
pairwise cipher in use for the connection.
Update ConfigureIPv{4,6}() parameters to simplify mapping our sets of
addresses and routes directly to D-Bus dictionaries. Split Cancel()
into CancelIPv{4,6}().
This file is meant as a sample and contains only the most typically
changed settings. For other settings users should refer to the
iwd.config manual page.
Document the new API that clients can use to get notified of new network
configuration and be responsible for committing it to the netdev, the
resolver, etc.
The Changed() method did not actually return anything, and in fact the
no_reply flag for that message was set.
Similarly, the Release method does not expect a reply.
