Struct allow named arguments, which seems easier to maintain instead of
a function with many arguments. Also, adding a new parameter does not
require changes to most of the callers.
The real advantage of this is that we encode all the search parameters
in one argument. And we can add that argument to
_match_section_infos_lookup(), alongside lookup by NMDevice or
NMPlatformLink.
All callers eventually want a boolean instead of a NMMatchSpecMatchType.
I think the NMMatchSpecMatchType enum still has value at the lower
layers, where the enum values are clearer (when reading the code). So
don't drop NMMatchSpecMatchType entirely.
However, let's add nm_match_spec_match_type_to_bool() to convert the
match-type to a boolean to avoid duplicating the code.
Arguably, a kernel link is needed for DHCP and so the interface name
univocally identifies a device (for example, the OVS interface). But
for consistency and clarity, store the device type to be used for
logging.
When logging, messages include the interface name to specify what
device they refer to. In most case the interface name is unique.
There are some devices that don't have a kernel link associated, and
their interface name is not guaranteed to be unique. This is currently
the case for OVS bridges and OVS ports. When reading a log with
duplicate interface names, it is difficult to understand what is
happening. And this is made worse by the fact that it is common
practice to assign the same name to all devices in a OVS hierarchy
(bridge, port, interface).
To make logs unambiguous, we want to print the device type together
with the name; however we don't want to *always* print the type
because in most cases it's not useful and it would consume valuable
real estate on the screen. Adopt a simple heuristic of showing the
type only for OVS devices.
This commit adds a helper function to return the device type to show
in logs, when it is needed.
This is rather bad, because if we reach the "goto again" case,
the error variable is not cleared. Subsequently passing the
error location to nm_device_reapply_finish() will trigger a glib
warning.

Once we start reconfiguring the system, we need to finish on all
interfaces. Otherwise, we might reconfigure some interfaces, abort
and leave the network broken. When that happens, a subsequent run
might also be unable to recover, because we are unable to reach the
HTTP meta data service.

network-online.target should not be reached before nm-cloud-setup
completes configuring the network, which may make user service get
started before the network is fully configured.
Setting nm-cloud-setup.service as "Before=network-online.target" would
maybe have already achieved that. However, also use a pre-up dispatcher
script, so that the device activation in NetworkManager is also waiting
for nm-cloud-setup to complete.

dnsmasq since 2.80 properly forwards all incoming queries with DO bit
set. That ensures even if the dnsmasq does not do validation, it will
always serve all DNSSEC records if the upstream server provides them.
Regardless local validation is enabled or disabled, it will always offer
all data required for validation to its clients.
But does not set AD bit on local responses unless it did the actual
validation itself.
In case users trust their connection to validating DNS server, they
would have to declare it by adding dnssec-proxy option to dnsmasq conf.d
directory. Because there is no negated no-dnssec-proxy, it cannot be
turned off. I think there is no good reason to be on for all cases and
it would be possible to enable it if still wanted. Move the decision to
the user.
That makes it conform with RFC 4035, paragraph 3.2.3.

It's not obvious, why we couldn't have a pending dever action
at that point. Maybe we cannot, but just to be explicit about it,
handle that we potentially might.
For example, we tend to schedule the timeout priv->carrier_defer_source
only from within nm_device_set_carrier() if `priv->carrier` is FALSE.
At the same time, nm_device_set_carrier() does nothing `if
(priv->carrier == carrier)`. So probably there is no problem.
However, we also set priv->carrier directly in
nm_device_set_carrier_from_platform() without clearing the timer. It's
hard to imagine whether there can be a case where we might have two
timeouts pending.
Between ppp 2.4.8 and 2.4.9, "rp-pppoe.so" was renamed to "pppoe.so" (and a
symlink created). Between 2.4.9 and 2.5.0, the symlink was dropped.
See-also: b2c36e6c0e
I guess, NetworkManager always meant to use ppp's "(rp-)pppoe.so"
plugin, and never what rp-pppoe provides.
If a user actually wants to use the plugin from rp-pppoe project, then
this is going to break. But it seams, we usually intend to use the
plugin from the ppp project.

Seen in NM 1.42.6 where there is now a ipv4.dns-data key which
have as signature:
dbus.Array([dbus.String('a.b.c.d')], signature=dbus.Signature('s'), variant_level=1)
This lead to the following exception:
Cannot convert array element to type 's': Must be string, not Variant
Moreover, the exception TypeError has no message field so it raised
another expcetion which gave me trouble to find what's going on.
Hence the addition of a log file from the previous commit

When a port cannot activate because the controller is not ready, it gets
blocked from autoconnect (see commit 725fed01cf ('policy: block
connection from autoconnect in case of failed dependency')).
Later, when the master activates we call activate_slave_connections()
(see commit 32efb87d4d ('core: unblock failed connections when the
master is available')), which unblocks those port profiles so they can
autoconnect.
However, imagine you add a port profile with autoconnect enabled. The
profile tries to autoconnect, finds no master and gets blocked. Then,
add the controller profile with autoconnect disabled. The controller is
not autoactivating, not calling activate_slave_connections() and the
profiles stay down.
Fix that by unblocking autoconnect of the ports when the controller
profile changes.
