9a797ddc41 meson: allow "soft-static" allocations for uids and gids in the initrd
The general idea with users and groups created through sysusers is that an
appropriate number is picked when the allocation is made. The number that is
selected will be different on each system based on the order of creation of
users, installed packages, etc. Since system users and groups are not shared
between installations, this generally is not an issue. But it becomes a problem
for initrd: some file systems are shared between the initrd and the host (/run
and /dev are probably the only ones that matter). If the allocations are
different in the host and the initrd, and files survive switch-root, they will
have wrong ownership.

This makes the gids build-time-configurable for all groups and users where
state may survive the switch from initrd to the host.

In particular, all "hardware access" groups are like this: files in /dev will
be owned by them.  Eventually the new udev would change ownership, but there
would be a momemnt where the files were owned by the wrong group. The
allocations are "soft-static" in the language of Fedora packaging guidelines:
the uid/gid will be used if possible, but we'll fall back to a different
one. TTY_GID is the exception, because the number is used directly.

Similarly, the possibility to configure "soft-static" uids is added for daemons
which may usefully run in the initramfs: systemd-network (lease information and
interface state is serialized to /run), systemd-resolve (stub files and
interface state), systemd-timesync (/run/systemd/timesync).

Journal files are owned by the group systemd-journal, and acls are granted
for wheel and adm.

systemd-oom and systemd-coredump are excluded from this patch: I assume that
oomd is not useful in the initrd, and coredump leaves no state (it only creates
a pipe in /run?).

The defaults are not changed: if nothing is configured, dynamic allocation will
be used. I looked at a Debian system, and the numbers are all different than
on Fedora.

For Fedora, see the list of uids and gids at https://pagure.io/setup/blob/master/f/uidgid.
In particular, systemd-network and systemd-resolve got soft-static numbers to
make it easy to transition from a non-host-specific initrd to a host system
already a few years back (https://bugzilla.redhat.com/show_bug.cgi?id=1102002).

I also requested static allocations for sgx, input, render in

f78ad5f046 test: enable fuzz regression tests by default
This ensures that the fuzz test code is also built by default.
It also increases the test coverage a bit. Compiling the tests
*with* sanitizers is painfully slow, so this is not enabled. But
just compiling them sauté is hardly noticable. Running the tests
increases the test count and runtime:
  622 tests, 26 s
to
  922 tests, 35 s
I think this is acceptable.

boot: add optional EFI SBAT support
Add SBAT support, when -Dsbat-distro value is specified. One can use
-Dsbat-distro=auto for autodetection of all sbat options. Many meson configure
options added to customize SBAT CSV values, but sensible defaults are auto
detected by default. SBAT support is required if shim v15+ is used to load
systemd-boot binary or kernel.efi (Type II BootLoaderSpec).

7d861e1263 meson, bpf: add HAVE_LIBBPF, BPF_FRAMEWORK options
* Add `bpf-framework` feature gate with 'auto', 'true' and 'false' choices
* Add libbpf [0] dependency
* Search for clang llvm-strip and bpftool binaries in compile time to
generate bpf skeleton.

For libbpf [0], make 0.2.0 [1] the minimum required version.
If libbpf is satisfied, set HAVE_LIBBPF config option to 1.

If `bpf-framework` feature gate is set to 'auto', means that whether
bpf feature is enabled or now is defined by the presence of all of
libbpf, clang, llvm and bpftool in build
environment.
With 'auto' all dependencies are optional.
If the gate is set to `true`, make all of the libbpf, clang and llvm
dependencies mandatory.
If it's set to `false`, set `BPF_FRAMEWORK` to false and make libbpf
dependency optional.

libbpf dependency is dynamic followed by the common pattern in systemd.

225d08b879 Add install-sysconfdir=no-samples option for (non-)installation of sample configs
By default, systemd installs various sample configuration files
containing commented-out defaults. Systems seeking to minimize the
number of files in /etc may wish to install directories and
configuration files that have semantic effects, but not install not
commented-out sample configuration files.

Turn install-sysconfdir into a multi-valued option, with a "no-samples"
value to skip installing sample-only configuration files.

8f20232fcb localed: Run locale-gen if available to generate missing locale
This change improves integration with distributions using locale-gen to
generate missing locale on-demand, like Debian-based distributions
(Debian/Ubuntu/PureOS/Tanglu/...) and Arch Linux.
We only ever enable new locales for generation, and never disable them.
Furthermore, we only generate UTF-8 locale.

This feature is only used if explicitly enabled at compile-time, and
will also be inert at runtime if the locale-gen binary is missing.

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 \

ceedbf8185 meson: add option for fexecve use
There are downsides to using fexecve:

when fexecve is used (for normal executables), /proc/pid/status shows Name: 3,
which means that ps -C foobar doesn't work. pidof works, because it checks
/proc/self/cmdline. /proc/self/exe also shows the correct link, but requires
privileges to read. /proc/self/comm also shows "3".

I think this can be considered a kernel deficiency: when O_CLOEXEC is used, this
"3" is completely meaningless. It could be any number. The kernel should use
argv[0] instead, which at least has *some* meaning.

I think the approach with fexecve/execveat is instersting, so let's provide it
as opt-in.

fc1a5d1a70 Also parse the minimum uid/gid values
We don't (and shouldn't I think) look at them when determining the type of the
user, but they should be used during user/group allocation. (For example, an
admin may specify SYS_UID_MIN==200 to allow statically numbered users that are
shared with other systems in the range 1–199.)

53393c894d Look at /etc/login.defs for the system_max_[ug]id values
It makes little sense to make the boundary between systemd and user guids
configurable. Nevertheless, a completely fixed compile-time define is not
enough in two scenarios:
- the systemd_uid_max boundary has moved over time. The default used to be
  500 for a long time. Systems which are upgraded over time might have users
  in the wrong range, but changing existing systems is complicated and
  expensive (offline disks, backups, remote systems, read-only media, etc.)
- systems are used in a heterogenous enviornment, where some vendors pick
  one value and others another.
So let's make this boundary overridable using /etc/login.defs.

Fixes #3855, #10184.

8ef8f3d5a7 meson: add a new -Dstandalone-binaries=true option
This adds an option to build standalone binaries that do not depend on the
systemd-shared library. This option can be handy to build binaries that can be
useful on a non-systemd system, binaries such as systemd-sysusers and
systemd-tmpfiles have been previously requested, but installing them with all
the required dependencies pulls in too much code that isn't really relevant for
those use cases. The standalone use case is also relevant in containers, where
minimizing the size of the container image is quite relevant.

For now, only `systemd-sysusers` is also built as a standalone binary.

The standalone binaries are installed as `/usr/bin/%{name}.standalone`, the
packaging system is reponsible for renaming those into the correct names
during the packaging step. RPM is able to do so with RemovePathPostfixes:

The default behavior is to build shared binaries only, since this option is
mainly intended for building distribution packages.

Tested that a proper separate binary is built when using this option and
that having it disabled (or using the default Meson configuration) does not
produce a binary for this option.

the opposite — the difference is small, and in some context the two-word version
does fit better. But in the tree, there are ~200 occurrences of the first, and
>1600 of the other, and consistent spelling is more important than any particular
spelling choice.

3602ca6f0c meson: make user $PATH configurable
This partially reverts db11487d10 (the logic to
calculate the correct value is removed, we always use the same setting as for
the system manager). Distributions have an easy mechanism to override this if
they wish.

I think making this configurable is better, because different distros clearly
want different defaults here, and making this configurable is nice and clean.
If we don't make it configurable, distros which either have to carry patches,
or what would be worse, rely on some other configuration mechanism, like
/etc/profile. Those other solutions do not apply everywhere (they usually
require the shell to be used at some point), so it is better if we provide
a nice way to override the default.

Fixes  #13469.

21d0dd5a89 meson: allow WatchdogSec= in services to be configured
As discussed on systemd-devel [1], in Fedora we get lots of abrt reports
about the watchdog firing [2], but 100% of them seem to be caused by resource
starvation in the machine, and never actual deadlocks in the services being
monitored. Killing the services not only does not improve anything, but it
makes the resource starvation worse, because the service needs cycles to restart,
and coredump processing is also fairly expensive. This adds a configuration option
to allow the value to be changed. If the setting is not set, there is no change.

My plan is to set it to some ridiculusly high value, maybe 1h, to catch cases
where a service is actually hanging.
