For internal compilation we want to be able to use deprecated
API without warnings.
Define the version min/max macros to effectively disable deprecation
warnings.
However, don't do it via CFLAGS option in the makefiles, instead hack it
to "nm-default.h". After all, *every* source file that is for internal
compilation needs to include this header as first.
Now we have:
"nm-sd.h" is a header file of NetworkManager with utilities
related to systemd. It can be used anywhere freely.
Also, systemd headers that are considered public API (like
"sd-event.h") can be used without restrictions.
When compiling the systemd sources, we always must include
"nm-sd-adapt.h" as first. Similarly, systemd headers must
not include "nm-sd-adapt.h", because they are either public
(in which case the adapter is not needed) or they are internal
(in which case they are themself included via a systemd source).
Sometimes, we must internal API (like "dhcp-lease-internal.h").
In this case, we also must include "nm-sd-adapt.h".
As the lldp API changed, adjust "nm-lldp-listener.c".
Note that the commit is not yet functional due to missing
sd_event_source_set_enabled() and sd_event_source_set_time().
We must export some symbols from NetworkManager binary so that
the device plugins can function. However, many symbols are truly
private and must not be exposed.
Especially, our internal clone of the systemd ABI must be hidden
to avoid resolution conflicts when loading any external systemd
libraries.
Add a new NMPNetns class. This allows creation, deletion and
switching of network namespaces. The API only offers push/pop
operations to switch the namespace. This way the API enforces
the user to always restore the previous namespace.
A NMPlatform instance not only uses the netlink socket, but also
sysfs, udev, ethtool, mii. Still, a NMPlatform instance lives
entirely inside one namespace and is not spanning multiple namespaces.
To properly support network namespaces, the platform instance must
switch the namespace as necessary, transparent to the caller.
Udev is only supported in the main namespace.
For now, network namespaces are not actually used and are disabled
via the NM_PLATFORM_NETNS_SUPPORT argument.

Most interestingly is also, whether we can link libsystemd.a without
having undefined references (which might be wrongly satisfied by an
externally loaded libsystem shared library.
"NetworkManagerUtils.h" contains a bunch of helper tools for core
daemon ("src/").
Unfortunately, it has dependencies to other parts of core,
such as "nm-device.h" and "nm-platform.h". Split out a part
of tools that are independent so that they can be used without
dragging in other dependencies.
"nm-core-utils.h" should only use libnm-core, "nm-logging.h"
and shared.
"NetworkManagerUtils.h" should provide all "nm-core-utils.h" and
possibly other utilities that have larger dependencies.
Add a new object which implements the logic for announcing IP
addresses and detecting duplicates using arping.
Based-on-patch-by: Jiří Klimeš <jklimes@redhat.com>
Up to now, the "include" directory contained (only) header files that were
used project-wide by libs, core, clients, et al.
Since the directory now also contains a non-header file, the "include"
name is misleading. Instead of adding yet another directory that is
project-wide, with non-header-only content, rename the "include"
directory to "shared".
The new object type represents tunnels over IPv4 and IPv6.
We have a single setting type (NMSettingIPTunnel) for tunnels and it
can't be shared among different device factories. So we define also a
single device type for all tunnels.
This new object will also represent GRE tunnels, which before were
instantiated as NMDeviceGre and had a ".Device.Gre" D-Bus
interface. This commit introduces a change in behavior.
A separate instance of the support plugin is spawned for each connection with
a different bus name. The bus name is passed via --bus-name <name> argument.
Plugins that support the feature indicate it with
support-multiple-connections=true key in the [VPN Connection] section.
The bus name is currently generated by adding a .<connection.uuid> to the VPN
service name. It's guarranteed unique, but if it proves to be too long or ugly
it can easily be replaced with something more meaningful (such as the same number
as is used for connection's DBus name).
NMVpnService has been removed and folded into NMVpnConnection. A
NMVpnConnection will spawn a service plugin instance whenever it is activated
and notices the bus name it needs is not provided.
The NMVpnManager no longer needs to keep track of the connections in use apart
for compatibility purposes with plugins that don't support the feature.
This adds a LldpNeighbors property to the Device D-Bus interface
carrying information about devices discovered through LLDP. The
property is an array of hashes and each hash describes the values of
LLDP TLVs for a specific neighbor.
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.

Optimally, we only make use of systemd API that is intended to be public
and that will be later part of the system-library. That is currently
not yet possible and we need "-Isrc/systemd/src/basic" to build
"nm-dhcp-systemd.h". Still, split the include paths to build systemd
code itself, contrary to the user of the API.
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)
(followed by some whitespace fixups in nm-settings-plugin.c, and a
Makefile.am fix for the rename)
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.
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.
Introduce some primitives to deliver messages about relevant
configuration changes to the Linux audit subsystem through libaudit
(if enabled at build time) and to the logging system.
Our gdbus generated types use the same names as their corresponding
"real" types, but with "NM" changed to "NMDBus".
Unfortunately, that means that introspection/nmdbus-manager.c (the
generated type for src/nm-manager.c) uses the same type name as the
entirely unrelated src/nm-dbus-manager.c.
Fix this by removing the "d" from src/nm-dbus-manager.c. (We could
rename the generated type instead, but then it becomes inconsistent
with all the other generated types, and we're already using it as
"NMDBusManager" in libnm/nm-manager.c.)
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.)
This allows packages to install their configuration snippets to
"/usr/", which is a better place for system-provided configuration
files then "/etc".
"/usr/lib/NetworkManager/conf.d/" is read first, so that the values
in /etc have higher priority.
In general, we want to move system-provided configuration away from
/etc, so that a user can do a "factory-reset" by purging /etc.

A class to do efficient lookup for multiple values based on a key.
The values are opaque pointers (void*). These values can be
associated with keys. The keys are an opaque type NMMultiIndexId
with arbitrary hash/equal functions.
Think of the keys being a set of buckets. A value can be associated with multiple
keys, just like with a regular GHashTable (i.e. it can be in multiple buckets).
But one key can also be associated with multiple values (i.e. one bucket can contain
multiple values). Hence the name "multi".
One bucket can only either contain a value or not. It cannot contain the same
value multiple times.
This is implemented as a hash of hashes with the outer keys being
NMMultiIndexId. The inner hashes are the "buckets".
This class will be used as an efficient lookup index to find all values
that belong to a certain key (bucket). Later we will ask for example
"Which IP4-Addresses are associated with a certain ifindex" and
efficiently retrieve the cached result list.
There is no general purpose file for platform utilities.
We only have nm-platform.h, which contains (mostly) functions
that operate on a NMPlatform instance (and that can be mocked
using NMFakePlatform).
Add a new file for independent utility functions. nm-platform-utils.c
should not call into functions having a NMPlatform instance, to
have them independent from platform caching and the platform
singleton.
