Names in header files should have an "nm" prefix. We do that pretty
consistently. Fix the offenders RfKillState and RfKillType.
Also, rename the RfKillState enums to follow the type name. For example,
NM_RFKILL_STATE_SOFT_BLOCKED instead of RFKILL_SOFT_BLOCKED.
Also, when we camel-case a typedef (NMRfKillState) we would want that
the lower-case names use underscore between the words. So it should be
`nm_rf_kill_state_to_string()`. But that looks awkward. So the right solution
here is to also rename "RfKill" to "Rfkill". That make is consistent
with the spelling of the existing `NMRfkillManager` type and the
`nm-rfkill-manager.h` file.
GObject Properties are flexible and powerful. In practice, NMDevicePrivate.rfkill_type
was only set once via the construct-only property NM_DEVICE_RFKILL_TYPE.
Which in turn was always set to a well-known value, only depending on the device
type.
We don't need this flexibility. The rfkill-type only depends on the
device type and doesn't change. Replace the property by a field in
NMDeviceClass.
For one, construct properties have an overhead, that the property setter is
called whenever we construct a NMDevice. But the real reason for this
change, is that a property give a notion as this could change during the
lifetime of a NMDevice (which it in fact did not, being construct-only).
Or that the type depends on something more complex, when instead it only
depends on the device type. A non-mutated class property is simpler,
because it's clear that it does not depend on the device instance,
only on the type/class.
Also, `git grep -w rfkill_type` now nicely shows the (few) references to
this variable and its easier to understand.
We don't run glib-mkenums for certain sources like "core" and
"libnm-glib-aux".
These annotations have no effect. Drop them.
They also mess with the automated formatting.
When the NM_UNMANAGED_PLATFORM_INIT flag is cleared last in
device_link_changed(), a recheck-assume is scheduled and then the
device goes immediately to UNAVAILABLE. During the state transition,
addresses and routes are removed from the interface. Then,
recheck-assume finds that the device can be assumed but it's too late
since the device was already deconfigured.
This is a problem as the whole point of assuming a device is to
activate a connection while leaving the device untouched.
In the NMCI "dracut_NM_vlan_over_bridge and dracut_NM_vlan_over_bond"
test, NM in real root tries to assume a vlan device that was activated
in initrd. When the interface gets deconfigured in UNAVAILABLE, the
connection to the NFS server breaks and the rootfs becomes
inaccessible.
The fix to this problem is to delay state transitions in
device_link_changed() to a idle handler, so that recheck-assume can
run before.

We use clang-format for automatic formatting of our source files.
Since clang-format is actively maintained software, the actual
formatting depends on the used version of clang-format. That is
unfortunate and painful, but really unavoidable unless clang-format
would be strictly bug-compatible.
So the version that we must use is from the current Fedora release, which
is also tested by our gitlab-ci. Previously, we were using Fedora 34 with
clang-tools-extra-12.0.1-1.fc34.x86_64.
As Fedora 35 comes along, we need to update our formatting as Fedora 35
comes with version "13.0.0~rc1-1.fc35".
An alternative would be to freeze on version 12, but that has different
problems (like, it's cumbersome to rebuild clang 12 on Fedora 35 and it
would be cumbersome for our developers which are on Fedora 35 to use a
clang that they cannot easily install).
The (differently painful) solution is to reformat from time to time, as we
switch to a new Fedora (and thus clang) version.
Usually we would expect that such a reformatting brings minor changes.
But this time, the changes are huge. That is mentioned in the release
notes [1] as
Makes PointerAligment: Right working with AlignConsecutiveDeclarations. (Fixes https://llvm.org/PR27353)

Completely rework IP configuration in the daemon. Use NML3Cfg as layer 3
manager for the IP configuration of an interface. Use NML3ConfigData as
pieces of configuration that the various components collect and
configure. NMDevice is managing most of the IP configuration at a higher
level, that is, it starts DHCP and other IP methods. Rework the state
handling there.
This is a huge rework of how NetworkManager daemon handles IP
configuration. Some fallout is to be expected.
It appears the patch deletes many lines of code. That is not accurate, because
you also have to count the files `src/core/nm-l3*`, which were unused previously.

The property `PROP_PORTS` should be of type g_param_spec_variant() with
variant 'ao'. This way the variant can be cached.
The deprecated property 'device::slaves' in
'src/core/devices/nm-device.c' must have the same getter-implementation,
returning the same GVariant instance.

dhcp-anycast-address is only set by OLPC mesh device. It's ugly to have
this in form of a nm_device_set_dhcp_anycast_address() method, because
that means to cache the address in NMDevice. Meaning, we have more state
in NMDevice, where it's not clear where it comes from.
Instead, whenever we need to DHCP anycast address, as the subclass to
provide it (if any). This way, it gets extracted from the currently
applied connection at the moment when it is needed. Beyond that, the
setting is not duplicated/cached in NMDevice anymore.
"nm-device.c" is huge, and it does complicated things like handling the
state of the device and IP configuration.
It also contains simpler, individual functions, like converting enums to
strings. Let's move those trivial functions to a new module, so that the
remaining part is smaller.
"nm-device-utils.[ch]" should only contain simpler functions that have
no complex behavior or state.

Currently "src/" mostly contains the source code of the daemon.
I say mostly, because that is not true, there are also the device,
settings, wwan, ppp plugins, the initrd generator, the pppd and dhcp
helper, and probably more.
Also we have source code under libnm-core/, libnm/, clients/, and
shared/ directories. That is all confusing.
We should have one "src" directory, that contains subdirectories. Those
subdirectories should contain individual parts (libraries or
applications), that possibly have dependencies on other subdirectories.
There should be a flat hierarchy of directories under src/, which
contains individual modules.
As the name "src/" is already taken, that prevents any sensible
restructuring of the code.
As a first step, move "src/" to "src/core/". This gives space to
reorganize the code better by moving individual components into "src/".
For inspiration, look at systemd's "src/" directory.
