Dracut when faced with an ipv6 only setup during kickstart will generate a ifcfg
file that sets the ipv4 address things to null but sets BOOTPROTO=static. This
makes network manager screw up because it expects an ipv4 address to be set.
Instead deal with this case by checking if we have any ipv4 addrs set, and if
not just disable ipv4. This fixes our inability to kickstart in our ipv6 only
clusters. Thanks,

Some initscripts variables can use "0" or "1" instead of more common
"yes", "no", for example REORDER_HDR.
And we also write REORDER_HDR=0|1 in writer.c, so we did not read REODER_HDR
correctly.
Fixes: ccea442504
The kernel defaults REORDER_HDR to 1 when creating a new VLAN, but
NetworkManager's VLAN flags property defaulted to 0. Thus REORDER_HDR was not
set for NM-created VLANs with default values.
We want to match the kernel default, so we change the default value for the
vlan.flags property. However, we do not want to change the flags for existing
connections if the property is missing in connection files. Thus we have to
update plugins for that. We also make sure that vlan.flags is always written
by 'keyfile' when the value is default. That way new connections have flags
property explicitly written and it will be loaded as expected.

For libnm library, "nm-dbus-interface.h" contains defines like the D-Bus
paths of NetworkManager. It is desirable to have this header usable without
having a dependency on "glib.h", for example for a QT application. For that,
commit c0852964a8 removed that dependancy.
For libnm-glib library, the analog to "nm-dbus-interface.h" is
"NetworkManager.h", and the same applies there. Commit
159e827a72 removed that include.
However, that broke build on PackageKit [1] which expected to get the
version macros by including "NetworkManager.h". So at least for libnm-glib,
we need to preserve old behavior so that a user including
"NetworkManager.h" gets the version macros, but not "glib.h".
Extract the version macros to a new header file "nm-version-macros.h".
This header doesn't include "glib.h" and can be included from
"NetworkManager.h". This gives as previous behavior and a glib-free
include.
For libnm we still don't include "nm-version-macros.h" to "nm-dbus-interface.h".
Very few users will actually need the version macros, but not using
libnm.
Users that use libnm, should just include (libnm's) "NetworkManager.h" to
get all headers.
As a special case, a user who doesn't want to use glib/libnm, but still
needs both "nm-dbus-interface.h" and "nm-version-macros.h", can include
them both separately.

The GATEWAY from /etc/sysconfig/network file is used as a default value when
no GATEWAY is in ifcfg file. However, we have to ignore that GATEWAY for
connections without static addresses. Otherwise such connections would be
invalid and would disappear after restart/reaload.
Some notes:
Putting GATEWAY into /etc/sysconfig/network is not recommended, because it
inherently belongs to the ifcfg file as it is a per-interface property.
The recommended practice is to specify GATEWAY in individual ifcfg files and
define DEFROUTE=no if the interface should not get the default route.
But we continue to read GATEWAY from /etc/sysconfig/network for compatibility
reasons.

A GObject interface, like a class, has two different C types
associated with it; the type of the "class" struct (eg, GObjectClass,
GFileIface), and the type of instances of that class/interface (eg,
GObject, GFile).
NetworkManager was doing this wrong though, and using the same C type
to point to both the interface's class struct and to instances of the
interface. This ends up not actually breaking anything, since for
interface types, the instance type is a non-dereferenceable dummy type
anyway. But it's wrong, since if, eg, NMDeviceFactory is a struct type
containing members "start", "device_added", etc, then you should not
be using an NMDeviceFactory* to point to an object that does not
contain those members.
Fix this by splitting NMDeviceFactory into NMDeviceFactoryInterface
and NMDeviceFactory; by splitting NMConnectionProvider into
NMConnectionProviderInterface and NMConnectionProvider; and by
splitting NMSettingsPlugin into NMSettingsPluginInterface and
NMSettingsPlugin; and then use the right types in the right places.
As a bonus, this also lets us now use G_DEFINE_INTERFACE.
Since there have not been separate system and user settings services
since 0.8, the "system" in NMSystemConfigInterface is kind of
meaningless. Rename it to NMSettingsPlugin, which describes what it
does better.
This is just:
git mv src/settings/nm-system-config-interface.h src/settings/nm-settings-plugin.h
git mv src/settings/nm-system-config-interface.c src/settings/nm-settings-plugin.c
perl -pi -e 's/SystemConfigInterface/SettingsPlugin/g;' \
-e 's/system_config_interface/settings_plugin/g;' \
-e 's/system-config-interface/settings-plugin/g;' \
-e 's/SYSTEM_CONFIG_INTERFACE/SETTINGS_PLUGIN/g;' \
-e 's/sc_plugin/settings_plugin/g;' \
-e 's/SC_PLUGIN/SETTINGS_PLUGIN/g;' \
-e 's/SC_IS_PLUGIN/SETTINGS_IS_PLUGIN/g;' \
-e 's/SC_TYPE_PLUGIN/SETTINGS_TYPE_PLUGIN/g;' \
-e 's/SCPlugin/SettingsPlugin/g;' \
-e 's/nm_system_config_factory/nm_settings_plugin_factory/g;' \
$(find src/settings -type f)

Makefile.am fix for the rename)
The logging macros _LOGD(), etc. are specific to each
file as they format the message according to their context.
Still, they were cumbersome to define and their implementation
was repeated over and over (slightly different at times).
Move the declaration of these macros to "nm-logging.h".
The source file now only needs to define _NMLOG(), and either
_NMLOG_ENABLED() or _NMLOG_DOMAIN.
This reduces code duplication and encourages a common implementation
and usage of these macros.
Advantages:
- use current best-pratice
- registers a weak-ref to clear @singleton_instance when the
instance gets destroyed
- logs creation and destruction of singleton
- on shutdown, destroy the singleton instance via
_nm_singleton_instance_register_destruction(). Note, that
we now have yet another reference to the singleton that is
owned by register-destruction.
There is no need to have a static @singleton variable.
The only caller of nm_settings_keyfile_plugin_new() is
NMSettings which owns the singleton instance.
A *_new() function should just create a new instance and
that's it. It's unexpected to reuse the same instance.
Move the check for a platform link before devtimeout_from_file(). The
check in the platform cache should be more performant and yield success
in most cases.
This can save reading and parsing the ifcfg-rh file.
If NIC related initialization takes a long time in udev processing, but we have
an ifindex from kernel, we still want to wait until udev is finished and the
device is really usable.
Check that by calling nm_platform_link_get_by_ifname() and checking @initialized,
which means udev is finished.

Port remaining bits to gdbus and remove stray dbus-glib references
Drop the dbus-glib version check from configure, since nothing depends
on new dbus-glib any more.
Move nm-dbus-glib-types.h and nm-gvaluearray-compat.h from include/ to
libnm-util/ since they are now only used by libnm-util and libnm-glib.
The localization headers are now included via "nm-default.h".
Also fixes several places, where we wrongly included <glib/gi18n-lib.h>
instead of <glib/gi18n.h>. For example under "clients/" directory.
This internal header file should be included by our internal source
code files and header files. It includes in one place other headers
that constitute to a minimal set of required headers. Most notably
this is <glib.h> and our "nm-glib.h" header.
Note that public header files and example source code cannot include
this file as "nm-default.h" is internal only.
Add NMExportedObject, make it the base class of all D-Bus-exported
types, and move the nm-properties-changed-signal logic into it. (Also,
make NMSettings use the same properties-changed code as everything
else, which it was not previously doing, presumably for historical
reasons).
(This is mostly just shuffling code around at this point, but
NMExportedObject will be more important in the gdbus port, since
gdbus-codegen doesn't do a very good job of supporting objects that
export multiple interfaces [as each NMDevice subclass does, for
example], so we will need more glue/helper code in NMExportedObject
then.)
Rather than randomly including one or more of <glib.h>,
<glib-object.h>, and <gio/gio.h> everywhere (and forgetting to include
"nm-glib-compat.h" most of the time), rename nm-glib-compat.h to
nm-glib.h, include <gio/gio.h> from there, and then change all .c
files in NM to include "nm-glib.h" rather than including the glib
headers directly.
(Public headers files still have to include the real glib headers,
since nm-glib.h isn't installed...)
Also, remove glib includes from header files that are already
including a base object header file (which must itself already include
the glib headers).
Add a file containing the defines like DBUS_INTERFACE_DBUS from
dbus-shared.h, and use it from the gdbus-using files.
Also, convert a bunch of other places that were previously hardcoding
the string values to use the defines instead, and fix the ifcfg-rh
plugin to properly namespace its own D-Bus-related defines.
Originally, if you change the ID of a connection,
the existing keyfile will not be renamed. That means
after renaming a connection, it's keyfile name will
mismatch.
Now, when th user modifies a connection via D-Bus and changes
the connection it, rename the file.

A GError should contain a nice, human readable error message. The
file:line prefix looks ugly. Also, the error messages are already
systemwide unique. So a user can easily grep for them and locate
the origin.
In some cases we want the returned value to be stripped. In some cases,
we want to read the raw value instead of the string parsed by GKeyFile.
Add an flags argument to nm_config_data_get_value(). It is up to the caller
to determine the exact meaning (and whether to strip).
By adding the flags argument, the caller can get the desired behavior easier
without having to workaround it afterwards. But more importantly, it becomes
apparent that there are different ways to retrieve the value and the caller
should decide on the details.
Some plugins had their local defines for the name of the sections and
keys in NMConfig. Move those defines to "nm-config.h".
Usually plugins make use of code in core, but not the other
way round. Defining the names inside "nm-config.h" is no violation of
that because the config section names are anyway not local to the
plugin, but global in the shared name-space with other settings.
For example, another plugins shouldn't reuse the section "ifnet".
For that reason, it is correct and consistent to move these defines
to "nm-config.h".
We don't use those names in core, we merely signal their existance.
We ought to set an error if we're returning NULL from
connection_from_file_full(). Also, printing out a warning ourselves makes no
sense -- the caller communicates this if we signal an error by returning NULL.
