This adds capability to hand over the network configuration from
OpenFirmware (and potentially other boot loaders with openfirmware
support such as U-Boot) to NetworkManager.
It's done analogously to ACPI/iBFT. In fact, the same ip=ibft command
line option is used, adding a more general ip=fw alias. This probably
deserves some documentation, but I'm not adding any at this time.

gtkdoc-scan supports regular expressions in the --ignore-decorators

This file causes a crash [1], add it to the tests.
Note that the test only check parsing the file and the
crash happens in the "upper" layers. So, it's not really
a test for the crash. But at least have such a file in
our repository.

BlueZ 5.0 was released in December 2012 and broke API with
BlueZ 4. NetworkManager supports Bluez 5 for years already.
Of course, version 4 is long gone by now, so remove it.

Completely rework how settings plugin handle connections and how
NMSettings tracks the list of connections.
Previously, settings plugins would return objects of (a subtype of) type
NMSettingsConnection. The NMSettingsConnection was tightly coupled with
the settings plugin. That has a lot of downsides.
Change that. When changing this basic relation how settings connections
are tracked, everything falls appart. That's why this is a huge change.
Also, since I have to largely rewrite the settings plugins, I also
added support for multiple keyfile directories, handle in-memory
connections only by keyfile plugin and (partly) use copy-on-write NMConnection
instances. I don't want to spend effort rewriting large parts while
preserving the old way, that anyway should change. E.g. while rewriting ifcfg-rh,
I don't want to let it handle in-memory connections because that's not right
long-term.
--
If the settings plugins themself create subtypes of NMSettingsConnection
instances, then a lot of knowledge about tracking connections moves
to the plugins.
Just try to follow the code what happend during nm_settings_add_connection().
Note how the logic is spread out:
- nm_settings_add_connection() calls plugin's add_connection()
- add_connection() creates a NMSettingsConnection subtype
- the plugin has to know that it's called during add-connection and
not emit NM_SETTINGS_PLUGIN_CONNECTION_ADDED signal
- NMSettings calls claim_connection() which hocks up the new
NMSettingsConnection instance and configures the instance
(like calling nm_settings_connection_added()).
This summary does not sound like a lot, but try to follow that code. The logic
is all over the place.
Instead, settings plugins should have a very simple API for adding, modifying,
deleting, loading and reloading connections. All the plugin does is to return a
NMSettingsStorage handle. The storage instance is a handle to identify a profile
in storage (e.g. a particular file). The settings plugin is free to subtype
NMSettingsStorage, but it's not necessary.
There are no more events raised, and the settings plugin implements the small
API in a straightforward manner.
NMSettings now drives all of this. Even NMSettingsConnection has now
very little concern about how it's tracked and delegates only to NMSettings.
This should make settings plugins simpler. Currently settings plugins
are so cumbersome to implement, that we avoid having them. It should not be
like that and it should be easy, beneficial and lightweight to create a new
settings plugin.
Note also how the settings plugins no longer care about duplicate UUIDs.
Duplicated UUIDs are a fact of life and NMSettings must handle them. No
need to overly concern settings plugins with that.
--
NMSettingsConnection is exposed directly on D-Bus (being a subtype of
NMDBusObject) but it was also a GObject type provided by the settings
plugin. Hence, it was not possible to migrate a profile from one plugin to
another.
However that would be useful when one profile does not support a
connection type (like ifcfg-rh not supporting VPN). Currently such
migration is not implemented except for migrating them to/from keyfile's
run directory. The problem is that migrating profiles in general is
complicated but in some cases it is important to do.
For example checkpoint rollback should recreate the profile in the right
settings plugin, not just add it to persistent storage. This is not yet
properly implemented.
--
Previously, both keyfile and ifcfg-rh plugin implemented in-memory (unsaved)
profiles, while ifupdown plugin cannot handle them. That meant duplication of code
and a ifupdown profile could not be modified or made unsaved.
This is now unified and only keyfile plugin handles in-memory profiles (bgo #744711).
Also, NMSettings is aware of such profiles and treats them specially.
In particular, NMSettings drives the migration between persistent and non-persistent
storage.
Note that a settings plugins may create truly generated, in-memory profiles.
The settings plugin is free to generate and persist the profiles in any way it
wishes. But the concept of "unsaved" profiles is now something explicitly handled
by keyfile plugin. Also, these "unsaved" keyfile profiles are persisted to file system
too, to the /run directory. This is great for two reasons: first of all, all
profiles from keyfile storage in fact have a backing file -- even the
unsaved ones. It also means you can create "unsaved" profiles in /run
and load them with `nmcli connection load`, meaning there is a file
based API for creating unsaved profiles.
The other advantage is that these profiles now survive restarting
NetworkManager. It's paramount that restarting the daemon is as
non-disruptive as possible. Persisting unsaved files to /run improves
here significantly.
--
In the past, NMSettingsConnection also implemented NMConnection interface.
That was already changed a while ago and instead users call now
nm_settings_connection_get_connection() to delegate to a
NMSimpleConnection. What however still happened was that the NMConnection
instance gets never swapped but instead the instance was modified with
nm_connection_replace_settings_from_connection(), clear-secrets, etc.
Change that and treat the NMConnection instance immutable. Instead of modifying
it, reference/clone a new instance. This changes that previously when somebody
wanted to keep a reference to an NMConnection, then the profile would be cloned.
Now, it is supposed to be safe to reference the instance directly and everybody
must ensure not to modify the instance. nmtst_connection_assert_unchanging()
should help with that.
The point is that the settings plugins may keep references to the
NMConnection instance, and so does the NMSettingsConnection. We want
to avoid cloning the instances as long as they are the same.
Likewise, the device's applied connection can now also be referenced
instead of cloning it. This is not yet done, and possibly there are
further improvements possible.
--
Also implement multiple keyfile directores /usr/lib, /etc, /run (rh #1674545,
bgo #772414).
It was always the case that multiple files could provide the same UUID
(both in case of keyfile and ifcfg-rh). For keyfile plugin, if a profile in
read-only storage in /usr/lib gets modified, then it gets actually stored in
/etc (or /run, if the profile is unsaved).
--
While at it, make /etc/network/interfaces profiles for ifupdown plugin reloadable.

This is inspired by the existing systemd integration, with a few differences:
* This parses the WPAD option, which systemd requested, but did not use.
* We hook into the DAD handling, only making use of the configured address
once DAD has completed successfully, and declining the lease if it fails.
There are still many areas of possible improvement. In particular, we need
to ensure the parsing of all options are compliant, as n-dhcp4 treats all
options as opaque, unlike sd-dhcp4. We probably also need to look at how
to handle failures and retries (in particular if we decline a lease).
We need to query the current MTU at client startu, as well as the hardware
broadcast address. Both these are provided by the kernel over netlink, so
it should simply be a matter of hooking that up with NM's netlink layer.
Contribution under LGPL2.0+, in addition to stated licenses.

The functionality of the ibft settings plugin is now handled by
nm-initrd-generator. There is no need for it anymore, drop it.
Note that ibft called iscsiadm, which requires CAP_SYS_ADMIN to work
([1]). We really want to drop this capability, so the current solution
of a settings plugin (as it is implemented) is wrong. The solution
instead is nm-initrd-generator.
Also, on Fedora the ibft was disabled and probably on most other
distributions as well. This was only used on RHEL.

When the code that generates "config-extra.h" changes, we want to regenerate
the file. Move that code to a separate makefile so we can add a
dependency.
Otherwise, we'd had to depend on "Makefile", which itself is generated by
Makefile.am.
Also, depend on "config.h" to regenerate it when ./configure runs and
touches that header. This may not cover all cases where ./configure's
configuration changes and a regeneration would be due. But such is life.
Also, most components depend on this header, so let various .dirstamp
files depend on it, so we are sure to build this first. That because,
autotools generates dependencies for header files automatically, but
that requires that the header file exist. Such automatic dependencies
don't work out-of-the-box for generated headers.

"config-extra.h" is really just like "config.h", except it works around some
limitations of autoconf.
If we depend on "Makefile", any changes to "Makefile.am" will cause a full
rebuild. We want to avoid that.
Instead, depend on "config.h". That one only changes when configure runs
again. And that's the better dependancy, because "config-extra.h" is
generated based on informations generated by configure (despite being
generated by "Makefile").

Not touching "config-extra.h" means that the target is rebuild every
time (because the timestampt does not get updated). On the other hand,
touching it will cause a full rebuild (which we often want to avoid).
The right solution is instead to depend on "config.h", which will be
done next.
This reverts commit 14271d84a0c9707e4efe5e32de9932032949c320.

This is to avoid updating config-extra.h timestamp very time one touches
Makefile.am, because it has a large dependency chain and makes
debugging of the Makefile inconvenient.

Before commit e3ac45c02610 the reader set the private key in the
setting using the libnm function, which also set the key as client
certificate if it was in PKCS #12 format.
After the commit, existing connections with a PKCS #12 private key but
without a client certificate became invalid. Restore the old behavior.

Glib has GValue which used for boxing value.
Add NMValueType enum, which has a similar purpose, but it's much more
limited.
- contrary to GValue, the type must be tracked separately from the
user-data. That is, the "user-data" is only a pointer of appropriate
type, and the knowledge of the actual NMValueType is kept separately.
This will be used to have a static list of meta-data that knows the
value types, but keeping the values independent of this type
information. With GValue this would not be possible.
- the use case is much more limited. Just support basic integers,
boolean and strings. Nothing fancy.
Note that we already do something similar at muliple places. See for
example NMVariantAttributeSpec and nm_utils_team_link_watcher_to_string().
These could/should instead use NMValueType.

When we link static libraries together, there must be no duplicate
symbols.
Since we have a lot of static/intermediate libraries, getting this right
is complicated and sometimes leads to ugly solutions.
As a new rule: don't let static libraries link with other static
libraries. Only binaries and libnm/libnm.la should explicitly link
with all the static libraries that they require.
There are exceptions: "src/libNetworkManager.la" and "libnm/liblibnm.la".
These are static, internal libraries, but they are basically *everything*
that ends up in "src/NetworkManager" and "libnm/libnm.la", respecitively.
Hence, these static libraries also link against other static libraries.
Another exception to this rule is "src/libNetworkManagerTest.la", for
similar reasons.
|
| | |
| |
| |
| |

We compile src/main.c as part of src/NetworkManager. Explicitly link with
glib, because that is required by the source code. Apparently, it also
works without this, but still do it for correctness.

| | |
| |
| |
| |
| |
| |
| | |
libnm/liblibnm.la compiles "libnm/nm-device.c" and "libnm/nm-client.c",
both include libudev.h.
Let's explicitly link this library with libudev.

We have "src/libNetworkManager.la" which is an intermediate static
library containing everything that ends up in "src/NetworkManager".
Likewise, add "libnm/liblibnm.la" to be the static library that contains
everything from "libnm/libnm.la".
The point of these libraries is to tie everything together that is used
by "src/NetworkManager" and "libnm/libnm.la" so that it also can be used
by unit-tests. Thereby, the unit tests will link statically against the
code of libnm. The problem is that the unit tests also want to access
internal functionality of libnm that is not accessible when dynamically
linking.
In part, this new library replaces "libnm/libnm-utils.la". The previous
name was confusing, because to us everything is an "utils", and it's
unclear what the purpose of that library was. Now the purpose should be
a bit clearer: liblibnm.la is a step before libnm.la, similar to what
libNetworkManager.la is to NetworkManager.
