8374cc6235 meson: warn if nobody-user and nobody-group are set to different name
It may work, but is very strange. So, let's warn about that.

v2:
Debian uses nobody and nogroup. Do not warn such case.

e783f95718 Rename "system-preset" source dir to "presets"
I want to add presets/user/ later. This mirrors the layout for units:
we have units/ and units/user. The advantage is that we avoid having yet
another directory at the top level.

84786b8e32 sysusers: Provide meson argument to set gid for 'users' group (#7533)
To allow better integration with distributions requiring an explicitly
set gid for the `users` group, provide the new `-Dusers-gid` option to
set to a new numeric value.

In the absence of a specified gid, we'll fallback to the default existing
behaviour of `-` as the gid value, to automatically assign the next available
gid on the system.

d9daae55d5 tmpfiles: add a special return code for syntax failures
In this way, individual errors in files can be treated differently than a
failure of the whole service.

A test is added to check that the expected value is returned.
Some parts are commented out, because it is not. This will be fixed in
a subsequent commit.

da495a0385 Add x-systemd.makefs option for fstab
I opted to completely generate a unit for both mount points and swaps. For
swaps, it would be possible to use fixed template unit like systemd-mkswap@.service,
because there's no information passed except the device name. For mount points,
that's not possible because both the device name and file system type need to
be passed. Nevertheless, I expect that options will need to passed to both mkfs
and mkswap, in which case it'll be necessary to create units of both types
anyway.

d6df583c87 networkd: introduce vxcan netdev. (#7150)
Similar to the virtual ethernet driver veth, vxcan implements a
local CAN traffic tunnel between two virtual CAN network devices.
When creating a vxcan, two vxcan devices are created as pair
When one end receives the packet it appears on its pair and vice
versa. The vxcan can be used for cross namespace communication.

18c8db140f meson: add -Wimplicit-fallthrough=3 to compilation options (#7393)
At some point before gcc-7 was released, -Wimplicit-fallthrough=3 was included
in -Wextra. The documentation for gcc-7.2.1-2.fc27.x86_64 still says that, but
empirical testing shows that it's not. The documentation also misstates that
-Wimplicit-fallthrough is equivalent to -Wimplicit-fallthrough=3.

Let's add -Wimplicit-fallthrough=3 explicitly to get the warnings if we regress.

Prompted by #7389.

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

I added my own copyright, even though other people modified those files too.
But this is mostly symbolic, so I hope that's OK.

Zbigniew Jędrzejewski-Szmek
5248e7e1f1 resolved,nss-myhostname: use _gateway for the gateway
This changes the symbolic name for the default gateway from "gateway" to
"_gateway". A new configuration option -Dcompat-gateway-hostname=true|false
is added. If it is set, the old name is also supported, but the new name
is used as the canonical name in either case. This is intended as a temporary
measure to make the transition easier, and the option should be removed
after a few releases, at which point only the new name will be used.

The old "gateway" name mostly works OK, but hasn't gained widespread acceptance
because of the following (potential) conflicts:
- it is completely legal to have a host called "gateway"
- there is no guarantee that "gateway" will not be registered as a TLD, even
  though this currently seems unlikely. (Even then, there would be no
  conflict except for the case when the top-level domain itself was being resolved.
  The "gateway" or "_gateway" labels have only special meaning when the
  whole name consists of a single label, so resolution of any subdomain
  of the hypothetical gateway. TLD would still work OK. )
Moving to "_gateway" avoids those issues because underscores are not allowed
in host names (RFC 1123, §2.1) and avoids potential conflicts with local or
global names.

v2:
- simplify the logic to hardcode "_gateway" and allow
  -Dcompat-gateway-hostname=true as a temporary measure.

003c887967 meson: install the git hook (#6425)
This was done autogen.sh previously and was dropped in
72cdb3e783. Let's add it back.
The meson configuration step is the only reasonable place.

Note that this only works for the most standard git dirs, e.g.
the hook will not be installed if git worktree is used or if
$GIT_DIR is specified, etc. I think that's OK because most of
the time meson will be run at least once in the original cloned
dir.

the advantage that the target is always available (if git is installed),
and the error message gives a hint what needs to be installed.

The naming is confusing, but etags(1) is pretty clear:
- emacs expects TAGS file in etags format
- vi expects tags file in ctags format
and automake docs are pretty clear too:
- tags target generates TAGS file
- ctags target generates tags file

f52b982cc9 meson: stop setting the linker (#6182)
If wanted, the linker can be set with LDFLAGS (LDFLAGS=-Wl,-fuse-ld=gold meson ...),
and setting it internally was interfering with that. It seems that both gold and
bfd work very well and quick, and the reasons we had to prefer gold are not relevant
anymore.

Three binaries would fail to link when ld.bfd was used and link-udev-shared was
false. Add -pthreads (again) to the failing binaries and synchronize the
dependency list between libsystemd-shared .a and .so versions.
Apart from allowing the build to succeed, this shouldn't have much effect becuase
systemd-networkd was already using pthreads.

94e2523b70 tests,meson: add test-bus-vtable, compiled as C and C++
This test is mostly a compilation test that checks that various defines in
sd-bus-vtable.h are valid C++. The code is executed, but the results are not
checked (apart from sd-bus functions not returning an error). test-bus-objects
contains pretty extensive tests for this functionality.

The C++ version is only added to meson, since it's simpler there.
Because of the .cc extension, meson will compile the executable with c++.

This test is necessary to properly check the macros in sd-bus-vtable.h. Just
running the headers through g++ is not enough, because the macros are not
exercised.

5486a31d28 nss-resolve: drop the internal fallback to libnss_dns (#5945)
If we could not communicate with systemd-resolved, we would call into
libnss_dns. libnss_dns would return NOTFOUND for stuff like "localhost" and
other names resolved by nss-myhostname, which we would fall under the !UNAVAIL=
condition and cause resolution to fail. So the following recommended
configuration in nsswitch.conf would not work:

   hosts: resolve [!UNAVAIL=return] dns myhostname

Remove the internal fallback code completely so that the fallback logic
can be configured in nsswitch.conf.

Tested with
   hosts: resolve [!UNAVAIL=return] myhostname
and
   hosts: resolve [!UNAVAIL=return] dns myhostname

87057e244b resolved: support libidn2 in addition to libidn
libidn2 2.0.0 supports IDNA2008, in contrast to libidn which supports IDNA2003.

https://bugzilla.redhat.com/show_bug.cgi?id=1449145
From that bug report:

Internationalized domain names exist for quite some time (IDNA2003), although
the protocols describing them have evolved in an incompatible way (IDNA2008).
These incompatibilities will prevent applications written for IDNA2003 to
access certain problematic domain names defined with IDNA2008, e.g., faß.de is
translated to domain xn--fa-hia.de with IDNA2008, while in IDNA2003 it is
translated to fass.de domain. That not only causes incompatibility problems,
but may be used as an attack vector to redirect users to different web sites.

v2:
- keep libidn support
- require libidn2 >= 2.0.0
v3:
- keep dns_name_apply_idna caller dumb, and keep the #ifdefs inside of the
  function.
- use both ±IDN and ±IDN2 in the version string

3a30f21ff8 meson: allow optional static linking of shared code in udev helpers
This makes the helper binaries significantly bigger (in some cases, the final
size depends on link options and optimization level), and is only useful for
distributions which want to provide the option to install udev without systemd.
As the linking is improved, the difference between the columns might shrink,
but it's unlikely that linking libshared statically could ever be more
efficient.

E.g. with -O0, no -flto:
                   (static) (shared)
src/udev/ata_id     999176    85696
src/udev/cdrom_id  1024344   111656
src/udev/collect    990344    81280
src/udev/scsi_id   1023592   115656
src/udev/v4l_id     811736    17744

When linked dynamically, install_rpath must be specified, so add that.

b2fc5836b2 meson: specify rpath on all executables linking to libshared

would be great if meson did too. Otherwise, it would be nice to simply attach
the information about necessary rpath to the library object, and have it used
automatically for all users. Dunno, maybe there's already a way to do this.

I used '$ORIGIN' for stuff installed into libexecdir, since that's where
libshared ends up, and a full path for everything else. The advantage of
using $ORIGIN is that those binaries can be started from $DESTDIR, which can
sometimes be useful.

link the test with nothing but the library being tested. Doing the linking by
hand did achieve that, but it caused a bigger issue: meson didn't know about
the dependency on the library. And the dependency cannot be added using
link_depends, because "link_depends arguments must be strings...", and this
does not work with a compilation target. So just link in the usual way and
accept the overlinking (for now).

826472ce36 meson: update linking for fixed meson linking
With mesonbuid/meson#1545, meson does not propagate deps of a library
when linking with that library. That's of course the right thing to do,
but it exposes a bunch of missing deps.

This compiles with both meson-0.39.1 and meson-git + pr/1545.

e0bec52f27 meson: add test-libudev-sym
This is slightly complicated by the fact that files('libudev.h') cannot be used
as an argument in custom_target command (string is required). This restriction
should be lifted in future versions of mesons, so this could be simplified.

37ab1a25ec meson: add test-libsystemd-sym, fix linking of libsystemd
This is quite messy. I think libtool might have been using something
like -Wl,--whole-archive, but I don't think meson has support for that.
For now, just recompile all the sources for linking into libsystemd
directly. This should not matter much for efficiency, since it's a
few small files.

94e75a5409 meson: create dirs and touch /usr
This is the equivalent of $(INSTALL_DIRS) and install-touch-usr-hook.
I did not bother to create the directories into which we install files,
since they will be created anyway.

v2:
- remove bashism

f4ee10a282 meson: create a static version of libshared and link libcore and some tests to it
This is what autoconf-based build does, and it makes test-bus-error and
test-engine able to access the bus error mapping table. OTOH, this is a heavy
price to pay: it would be excellent to link libcore.a to libsystemd-shared-NNN.so.
Otherwise we duplicate the same code in 'systemd' and 'libsystemd-shared-NNN.so'.

-rwxrwxr-x. 1 4075544 Apr  6 20:30 systemd* <-- libcore linked against libsystemd-shared.so
-rwxrwxr-x. 1 5596504 Apr  9 14:07 systemd* <-- libcore linked against libsystemd-shared.a

v2:
- update for 6b5cf3ea62

6b30f2801b meson: include the library symbol version list in link_depends
This is pretty ugly, because I don't know how to use a single
definition for two purposes:
- --version-script needs a path relative to the build root
- link_depends needs a path relative to source root
Also, link_depends does not accept files() output
[https://github.com/mesonbuild/meson/issues/1172], and I don't see a way to go
from files() output to a string path that can be used to craft the -Wl arg.

Ideally, a single files() result could be used in both places.
I'm leaving this as a separate commit for now.

572baca1d4 meson: add option to install tests
Instead of a separate target as with make, it is decided at configure time
whether to install tests as part of the install target. The effect should be
the same.

69e96427a2 meson: define tests
Tests can be run with 'ninja-build test' or using 'mesontest'.
'-Dtests=unsafe' can be used to include the "unsafe" tests in the
test suite, same as with autotools.

v2:
- use more conf.get guards are optional components
- declare deps on generated headers for test-{af,arphrd,cap}-list

v3:
- define environment for tests

  Most test don't need this, but to be consistent with autotools-based build, and
  to avoid questions which tests need it and which don't, set the same environment
  for all tests.

v4:
- rework test generation

  Use a list of lists to define each test. This way we can reduce the
  boilerplate somewhat, although the test listings are still pretty verbose. We
  can also move the definitions of the tests to the subdirs. Unfortunately some
  subdirs are included earlier than some of the libraries that test binaries
  are linked to.  So just dump all definitions of all tests that cannot be
  defined earlier into src/test. The `executable` definitions are still at the
  top level, so the binaries are compiled into the build root.

v5:
- tag test-dnssec-complex as manual

v6:
- fix HAVE_LIBZ typo
- add missing libgobject/libgio defs
- mark test-qcow2 as manual

d68b342b03 meson: add TAGS target
Quite necessary for all the emacs users out there ;)

v2:
- fix error with etags or git are not found

v3:
- move the definition of git and etags up so it's available for man/

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
