db6406e97e network: fix 6rd tunnel link section name
Spotted randomly when going through CI logs:

systemd-udevd[658]: /usr/lib/systemd/network/80-6rd-tunnel.link:21: Unknown section 'Network'. Ignoring.

Follow-up for 658169e6d3.

658169e6d3 network: take explicit ownership of our own interfaces
This is a follow-up for #30786 and uses it to assign
ID_NET_MANAGED_BY=io.systemd.Network to all all network interfaces that
we consider ours to manage. This should hopefully have the effect that
other well-behaving managers won't fight for these devices.

This doesn't bother with network interfaces we match inside containers,
since udev is not available there anyway.

205a30fa13 meson: always install network example files
I started working on integrating this in the Fedora package and realized that
the example files should be installed regardless of the renamed files when
default-network=true is used. This is because the renamed files become part of
a different package, and we want to have the other files which are used as
documentation in the main package anyway.

f139393dd2 network: use Kind= instead of Driver=
networkd ignores errors in reading driver through ethtool. The kind of
network interface is retrieved through netlink, and networkd checks
checks many failures. So, using Kind= should be safer.

No functional change, just for safety.

e941da8425 meson: fix install path of example .network files
It seems that when 'rename' field is set, the path (instead of the
filename) is appended to the 'install_dir'.

9b7a624267 network: add meson option to rename .example files on install
Also this renames 80-ethernet.network.example -> 89-ethernet.network.example,

Ethernet interfaces.

e6ba085398 network: add default .network file matching ID_NET_AUTO_LINK_LOCAL_ONLY=1
This is name ".network.example" for now, to match the existing
80-ethernet.network file.

I think it would make sense to actually install this by default if told
so via a meson file (and then hopefully this would happen even on
Fedora, though in a split off RPM or so). However, we aren't there yet,
hence for now, just ship the .network files as example, like the others.

3fe96b6c32 network: change license of examples to MIT-0
Arguably, CC0 is just fine for examples since they are not code. But it's
easier to be consistent and just use MIT-0 for all "documentation". Thus,
the license is changed similarly code examples under man/.

9bd4181ef5 network: add example file that enables DHCP on ethernet links

later on, we can always adjust the instructions.

2ec6191c38 networkd: Enable IPv6SendRA on builtin network files
RAs trigger neighbor discovery which allows users to query the
LL address of the container/VM via `ip neighbor get dev`. This is
useful as it gives users an easy way to connect to the container
without needing LLMNR or mDNS to resolve the hostname of the container
to an IP address. In practice, this allows connecting with only
networkd enabled and without resolved running in the host/container.

d7aa78c32f meson: add option to skip installing to $sysconfdir
This is useful for development where overwriting files out side
the configured prefix will affect the host as well as stateless
systems such as NixOS that don't let packages install to /etc but handle
configuration on their own.

Alternative to https://github.com/systemd/systemd/pull/17501

tested with:

$ mkdir inst build && cd build
$ meson \
  -Dcreate-log-dirs=false \
  -Dsysvrcnd-path=$(realpath ../inst)/etc/rc.d \
  -Dsysvinit-path=$(realpath ../inst)/etc/init.d \
  -Drootprefix=$(realpath ../inst) \
  -Dinstall-sysconfdir=false \
  --prefix=$(realpath ../inst) ..

a9eedd3cf7 network: install wifi-adhoc.network by default, make wifi-{ap,station} examples
I think 80-wifi-adhoc.network is safe enough, since it just enables
the link-local addressing. But the other two enable DHCP in client
or server modes, and we should not do this by default.

3907446f02 link-config: add "keep" policy and use it by default
If "keep" policy is specified, and the interface has a name that is
NET_NAME_USER or NET_NAME_RENAMED, we stop processing rules. "keep" should
probably be specified either first or last depending on the preference.

This partially reimplements 55b6530baa, in the
sense that if the "keep" policy is not specified, and if the interface has
a NamingPolicy, it will be renamed, even if it had a name previously.
So this breaks backwards compatibility in this case, but that's more in line
with what users expect.

Closes #9006.

11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

3a726fcd08 Add license headers and SPDX identifiers to meson.build files
So far I avoided adding license headers to meson files, but they are pretty

2c201c2140 meson: use booleans for conf.set and drop unecessary conditionals
Using conf.set() with a boolean argument does the right thing:
either #ifdef or #undef. This means that conf.set can be used unconditionally.

Previously I used '1' as the placeholder value, and that needs to be changed to
'true' for consistency (under meson 1 cannot be used in boolean context). All
checks need to be adjusted.

5c23128dab meson: build systemd using meson
It's crucial that we can build systemd using VS2010!

... er, wait, no, that's not the official reason. We need to shed old systems
by requring python 3! Oh, no, it's something else. Maybe we need to throw out
345 years of knowlege accumulated in autotools? Whatever, this new thing is
cool and shiny, let's use it.

This is not complete, I'm throwing it out here for your amusement and critique.

- rules for sd-boot are missing. Those might be quite complicated.

- rules for tests are missing too. Those are probably quite simple and
  repetitive, but there's lots of them.

- it's likely that I didn't get all the conditions right, I only tested "full"
  compilation where most deps are provided and nothing is disabled.

- busname.target and all .busname units are skipped on purpose.

  Otherwise, installation into $DESTDIR has the same list of files and the
  autoconf install, except for .la files.

It'd be great if people had a careful look at all the library linking options.
I added stuff until things compiled, and in the end there's much less linking
then in the old system. But it seems that there's still a lot of unnecessary
deps.

meson has a `shared_module` statement, which sounds like something appropriate
for our nss and pam modules. Unfortunately, I couldn't get it to work. For the
nss modules, we need an .so version of '2', but `shared_module` disallows the
version argument. For the pam module, it also didn't work, I forgot the reason.

The handling of .m4 and .in and .m4.in files is rather awkward. It's likely
that this could be simplified. If make support is ever dropped, I think it'd
make sense to switch to a different templating system so that two different
languages and not required, which would make everything simpler yet.

v2:
- use get_pkgconfig_variable
- use sh not bash
- use add_project_arguments

v3:
- drop required:true and fix progs/prog typo

v4:
- use find_library('bz2')
- add TTY_GID definition
- define __SANE_USERSPACE_TYPES__
- use join_paths(prefix, ...) is used on all paths to make them all absolute

v5:
- replace all declare_dependency's with []
- add more conf.get guards around optional components

v6:
- drop -pipe, -Wall which are the default in meson
- use compiler.has_function() and compiler.has_header_symbol instead of the
  hand-rolled checks.
- fix duplication in 'liblibsystemd' library name
- use the right .sym file for pam_systemd
- rename 'compiler' to 'cc': shorter, and more idiomatic.

v7:
- use ENABLE_ENVIRONMENT_D not HAVE_ENVIRONMENT_D
- rename prefix to prefixdir, rootprefix to rootprefixdir
  ("prefix" is too common of a name and too easy to overwrite by mistake)
- wrap more stuff with conf.get('ENABLE...') == 1
- use rootprefix=='/' and rootbindir as install_dir, to fix paths under
  split-usr==true.

v8:
- use .split() also for src/coredump. Now everything is consistent ;)
- add rootlibdir option and use it on the libraries that require it

v9:
- indentation

v10:
- fix check for qrencode and libaudit

v11:
- unify handling of executable paths, provide options for all progs

  This makes the meson build behave slightly differently than the
  autoconf-based one, because we always first try to find the executable in the
  filesystem, and fall back to the default. I think different handling of
  loadkeys, setfont, and telinit was just a historical accident.

  In addition to checking in $PATH, also check /usr/sbin/, /sbin for programs.
  In Fedora $PATH includes /usr/sbin, (and /sbin is is a symlink to /usr/sbin),
  but in Debian, those directories are not included in the path.

  C.f. https://github.com/mesonbuild/meson/issues/1576.

- call all the options 'xxx-path' for clarity.
- sort man/rules/meson.build properly so it's stable
