Like with "libnm-core/", split "libnm/" into different directories for
the public headers, for the implementation and for the helper "aux"
library.
|
| |
|
|
| |
"src/libnm-{glib-aux,log-null,log-core}"

"libnm-core/" is rather complicated. It provides a static library that
is linked into libnm.so and NetworkManager. It also contains public
headers (like "nm-setting.h") which are part of public libnm API.
Then we have helper libraries ("libnm-core/nm-libnm-core-*/") which
only rely on public API of libnm-core, but are themself static
libraries that can be used by anybody who uses libnm-core. And
"libnm-core/nm-libnm-core-intern" is used by libnm-core itself.
Move "libnm-core/" to "src/". But also split it in different
directories so that they have a clearer purpose.
The goal is to have a flat directory hierarchy. The "src/libnm-core*/"
directories correspond to the different modules (static libraries and set
of headers that we have). We have different kinds of such modules because
of how we combine various code together. The directory layout now reflects
this.

"nm-version-macros.h" is used directly by libnm-core and indirectly by
libnm and core.
Let's not have it randomly under shared/. Move it closer to where it's
used.

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.

NetworkManager core is huge. We should try to split out
parts that are independent.
Platform code is already mostly independent. But due to having it
under "src/", there is no strict separation/layering which determines
the parts that can work independently. So, while the code is mostly
independent (in practice), that is not obvious from looking at the
source tree. It thus still contributes to cognitive load.
Add a shared library "shared/nm-platform", which should have no
dependencies on libnm-core or NetworkManager core.
In a first step, move the netlink code there. More should follow.

I still don't understand why we get now these ".actions" build
artifacts. Anyway, I don't think we need to care. Just ignore
it.

We use a linker version script "NetworkManager.ver", to hide
symbols from NetworkManager that are not used. That is important
due to our habit of using internal helper libraries that we link
statically everywhere, without handpicking the symbols we actually
need. We want the tooling to get rid of unnecessary symbols.
However, NetworkManager loads shared libraries for settings and device
plugins. These libraries require symbols from the NetworkManager binary,
but which one depends on build options. Hence, we also generate
"NetworkManager.ver" by the "tools/create-exports-NetworkManager.sh"
script.
For that the script uses "nm" to find symbols that are undefined in the
plugin libraries but defined in NetworkManager. With autotools the
script looked at "./src/.libs/libNetworkManager.a" to find the present
symbols. Note that for meson that already didn't work, and we build
instead an intermediate NetworkManager binary first (with all symbols
exposed). With LTO, "nm" doesn't find all symbols in
"./src/.libs/libNetworkManager.a", and consequently they are not
exported and dropped/hidden.
This also causes unit tests to fail with LTO, because our test script
"tools/check-exports.sh" catches such bugs.
Fix that by also with autotools generate a complete "NetworkManager-all-sym"
binary that is used to generate "NetworkManager.ver", before rebuilding
"NetworkManager" again.

Our "nm-json-aux.h" redefines various things from <jansson.h> header.
Add a unit test that checks that what we redefine exactly matches what
libjansson would provide, so that they are compatible.

We have the correct meta-data of supported properties for nmcli. It is
in clients/common. Use that for generating the manual page instead of
the properties that are part of libnm (some properties may be in libnm
but not supported by nmcli, or some properties may not be GObject
properties, and not detected as by GObject introspection).

"nm-settings-docs-nmcli.xml" will be generated by a tool that depends on
"clients/common/". The file should thus not be in libnm directory, otherwise
there is a circular dependency.
Move the file to "man/" directory.
For consistency, also move "nm-settings-docs-dbus.xml". Note that we
cannot move "nm-settings-docs-gir.xml" to "man/", because that one is
needed for building clients.

A significant part of NetworkManager's API are the connection profiles, documented
in `man nm-settings*`. But there are different aspects about profiles, depending
on what you are interested. There is the D-Bus API, nmcli options, keyfile format,
and ifcfg-rh format. Additionally, there is also libnm API.
Add distinct manual pages for the four aspects. Currently the two new manual
pages "nm-settings-dbus" and "nm-settings-nmcli" are still identical to the
former "nm-settings.5" manual. In the future, they will diverge to
account for the differences.
There are the following aspects:
- "dbus"
- "keyfile"
- "ifcfg-rh"
- "nmcli"
For "libnm" we don't generate a separate "nm-settings-libnm" manual
page. That is instead documented via gtk-doc.
Currently the keyfile and ifcfg-rh manual pages only detail settings
which differ. But later I think also these manual pages should contain
all settings that apply.

"nm-settings-docs-dbus.xml" is "nm-settings-docs-gir.xml" merged with
"nm-property-infos-dbus.xml". The name should reflect that, also because
we will get more files with this naming scheme.
|

|
|
|
|
|
|
|
|
|

The name is bad. For one, we will have more files of the same format
("nm-settings-docs-nmcli.xml").
Also, "libnm/nm-settings-docs.xml" and "libnm/nm-property-docs.xml" had
basically the same file format. Their name should be similar.
Also the tool to generate the file should have a name that reminds to
the file that it creates.
|
| |
|
|
|
|
|
|
|
|
| |
The naming was inconsistent. Rename.
- all the property infos of this kind a now consistently called
"libnm/nm-property-infos-$TAG.xml".
- the script to generate files "libnm/nm-property-infos-$TAG.xml" is
now called "libnm/generate-docs-nm-property-infos.pl".

"shared/nm-glib-aux/tests"
"shared/nm-utils" got long renamed and split into separate parts. The remaining
tests are really to test nm-std-aux and nm-glib-aux (no libnm dependencies). Move
the tests to the appropriate place.

This is a tool for automatically configuring networking in a cloud
environment.
Currently it only supports IPv4 on EC2, but it's intended for extending
to other cloud providers (Azure). See [1] and [2] for how to configure
secondary IP addresses on EC2. This is what the tool currently aims to
do (but in the future it might do more).
[1] https://aws.amazon.com/premiumsupport/knowledge-center/ec2-ubuntu-secondary-network-interface/
It is inspired by SuSE's cloud-netconfig ([1], [2]) and ec2-net-utils
package on Amazon Linux ([3], [4]).
[1] https://www.suse.com/c/multi-nic-cloud-netconfig-ec2-azure/
[2] https://github.com/SUSE-Enceladus/cloud-netconfig
[3] https://github.com/aws/ec2-net-utils
[4] https://github.com/lorengordon/ec2-net-utils.git
It is also intended to work without configuration. The main point is
that you boot an image with NetworkManager and nm-cloud-setup enabled,
and it just works.

This adds LGPL and GFDL texts from the GNU web site and updates the GPL
one:
COPYING: https://www.gnu.org/licenses/old-licenses/gpl-2.0.txt
COPYING.LGPL: https://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt
COPYING.GFDL: https://www.gnu.org/licenses/old-licenses/fdl-1.1.txt
The update to the GPL text is purely cosmetic. However, shipping the
exact same file as GNU publishes may help distros that deduplicate the
license texts or hardlink duplicates.

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.

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.

For the most part, we only have one main .gitignore file.
There were a few nested files, merge them into the main file.
I find it better to have only one gitignore file, otherwise the
list of ignored files is spread out through the working directory.

We already have "libnm-core/tests/test-keyfile.c" from which we build
"test-keyfile".
Our test binaries should be named the following:
- "*/tests/test-*"
- the test binary "*/tests/test-*" should be build from a source file
"*/tests/test-*.c". Meaning: the source's and executable's name should
correspond.
- test binaries should be named uniquely. Also, because older meson
versions don't like having the same binary name more than once.
Rename to avoid the duplicate name.

These tests cannot (easily) be under "shared/nm-libnm-core-aux/tests"
because libnm/libnm-core requires code under shared while
"nm-libnm-core-aux" requires libnm/libnm-core. With autotools that is
not problem, but with meson we include sub directories in a particular
order and there is no way to foward declare stuff (AFAIK). To avoid
the circular dependency, add the tests to "clients/common/tests", which
is always built last.

"shared/nm-utils" is a loose collection of utility functions.
There is a certain aim that they can be used independently.
However, they also rely on each other.
Add a test that we can build a minimal shared library with
these tools, independent of libnm-core.

nm-initrd-generator scans the command line for options relevant to network
configuration and creates configuration files for an early instance of
NetworkManager run from the initial ramdisk during early boot.

This is loosely based on nms-ibft-reader, but with some significant
changes. Notably, it parses /sys/firmware/ibft directly instead of
iscsiadm output.
iscsiadm is not available on early boot (perhaps it's too large) and
turns out that parsing sysfs directly is easier and more
straightforwared anyways. A win-win situation.
It is not useful alone, it's in a separate commit just for the sake of
easier review.

via CFLAGS
1) the command line gets shorter. I frequently run `make V=1` to see
the command line arguments for the compiler, and there is a lot
of noise.
2) define each of these variables at one place. This makes it easy
to verify that for all compilation units, a particular
define has the same value. Previously that was not obvious or
even not the case (see commit e5d1a71396e107d1909744d26ad401f206c0c915
and commit d63cf1ef2faba57595112a82e962b9643cce4718).
The point is to avoid redundancy.
3) not all compilation units need all defines. In fact, most modules
would only need a few of these defines. We aimed to pass the necessary
minium of defines to each compilation unit, but that was non-obvious
to get right and often we set a define that wasn't used. See for example
"src_settings_plugins_ibft_cppflags" which needlessly had "-DSYSCONFDIR".
This question is now entirely avoided by just defining all variables in
a header. We don't care to find the minimum, because every component
gets anyway all defines from the header.
4) this also avoids the situation, where a module that previously did
not use a particular define gets modified to require it. Previously,
that would have required to identify the missing define, and add
it to the CFLAGS of the complation unit. Since every compilation
now includes "config-extra.h", all defines are available everywhere.
5) the fact that each define is now available in all compilation units
could be perceived as a downside. But it isn't, because these defines
should have a unique name and one specific value. Defining the same
name with different values, or refer to the same value by different
names is a bug, not a desirable feature. Since these defines should
be unique accross the entire tree, there is no problem in providing
them to every compilation unit.
6) the reason why we generate "config-extra.h" this way, instead of using
AC_DEFINE() in configure.ac, is due to the particular handling of
autoconf for directory variables. See [1].
With meson, it would be trivial to put them into "config.h.meson".
While that is not easy with autoconf, the "config-extra.h" workaround
seems still preferable to me.
