[PATCH 1/5] network: remove 'path' from settings_load_pt_ecc

[PATCH 1/5] network: remove 'path' from settings_load_pt_ecc

[James Prestwood]

The path argument was used purely for debugging. It can be just as
informational printing just the SSID of the profile that failed to
parse the setting without requiring callers allocate a string to
call the function.

[PATCH 2/5] knownnetworks: network: support updating known network settings

[James Prestwood]

Currently if a known network is modified on disk the settings are not
reloaded by network. Only disconnecting/reconnecting to the network
would update the settings. This poses an issue to DPP since its
creating or updating a known network after configuration then trying
to connect. The connection itself works fine since the PSK/passphrase
is set to the network object directly, but any additional settings
are not updated.

To fix this add a new UPDATED known network event. This is then
handled from within network and all settings read from disk are
applied to the network object.

Okay, so you chose option 2...

I'm not sure you really want to yank the PSK or Passphrase actually.  These are 
obtained via the Agent and should take precedence.

I suspect you're better off copying all the settings (with the exception of 
Security) over to the open settings object instead,

Don't you want to update the settings even for the EVENT_ADDED case?  Something 
like this might happen for example:

- User issues Network.Connect() for an unknown network
- At the same time, the network file is written to /var/lib/iwd

Connect proceeds to win the race, with the EVENT_ADDED event coming in shortly 
after.  Don't you want any additional settings (say DHCP hostname or whatever) 
to be used when the network succeeds in associating?

[PATCH 3/5] dpp: fix extra settings not being used when connecting

[James Prestwood]

After DPP completes all settings are written and synced to disk as
well as credentials set into the network object itself. The way
network/knownnetworks worked at the time did not actually re-load
these settings before the connection attempt was made which means
that extra settings not set into the network object were not used,
i.e. Hidden/Sendhostname. The connection itself always succeeded
because the network object was given the credentials directly via
setters.

Now network and knownnetworks support updating on the directory
watch callback and ADDED/UPDATED known network events. Take advantage
of this and if the network object already exists after DPP (from a
prior scan) wait unil known networks adds/updates the network and
issue the connection after that.

[PATCH 4/5] auto-t: add DPP tests to check extra settings are applied

[James Prestwood]

In order to test that extra settings are applied prior to connecting
two tests were added for hidden networks as well as one testing if
there is already an existing profile after DPP.

The reason hidden networks were used was due to the requirement of
the "Hidden" settings in the profile. If this setting doesn't get
sync'ed to disk the connection will fail.
