struct timex is defined by sys/timex.h -> bits/timex.h.
Glibc includes the header in time.h, but let's explicitly include it
when the struct is used.
Similar to 4f18ff2e29, but for sys/timex.h.
These source files uses symbols provided by sys/stat.h, e.g. struct stat,
S_IFREG, S_IFBLK, and so on. Let's explicitly include sys/stat.h where
necessary.
Glibc's fcntl.h includes bits/stat.h, which provides these symbols, so
these symbols can be used without explicitly including sys/stat.h. But,
based on the discussion in #37922, we should explicitly include relevant
headers, and should not rely on the indirect inclusion.
Similar to 4f18ff2e29, but for sys/stat.h.
For some fields, we perform careful parsing and verification on the sender
side. For other fields, we accept any string or strv. I think that actually
this is fine: we should optimize for the correct case, i.e. the user runs a
command that is valid. The server must perform parsing in all cases, so doing
the verification on the sender side doesn't add value. When doing parsing
locally, in case of invalid or unsupported input, we would generate the error
message locally, so we would avoid the D-Bus call, but the message itself is
not better and from the user's point of view, the result is the same. And by
doing the parsing only on the server side, we deal better with the case where
the sender has an older version of the software. By not doing verification, we
implicitly "support" new values. And when the sender has a newer version that
supports additional fields, that does not help as long as the server uses an
older version. So in case of version mismatches, parsing on the server side is
as good or better.

This changes little in behaviour, the conceptual part is more important. The
non-Ex variant is the actual name on the command line, and we should use the
non-Ex D-Bus property too, if it works. This increases compatibility with old
versions. But the code was mostly doing the right thing. Even the tests tested
the right thing.
Follow-up for b3d593673c and

The test is simplified by taking advantage of the fact that both names
on the commandline are supposed to behave identically.
Partially resolves https://github.com/systemd/systemd/issues/37174.
We generally want to have error messages with a fixed structure that convey the
important information, i.e. field name, error value, and the offending text for
options that take short values. (The text is not printed for strings encoded with
base64 and hexmem or for credentials.)
Let's use a helper that prints the message in a fixed format in the majority of
cases. In the few places where a custom message is useful, the helper is not
used. The helper:
- prints the field name, value, and error info,
- quotes the value,
- handles -ENOMEM, so we don't need to handle it separately everywhere.
When this code was originally written, parse functions would return -1
as error. Nowadays day all return a good errno, so it is fine if we print
the corresponding strerror.
exec_command_flags_to_strv() should not fail, unless we screwed up, so assert
instead of returning an error. Also, no need to strdup constant _PATH_BSHELL;
drop that so that we can get rid of the oom error handling. Finally, rename
l → cmdline for clarity.
If one of the header is included in a C++ source file, then using
_Static_assert() triggers compile error for some reasons.
Let's use static_assert(), which can be used by both C and C++ code.
The slow tests have timed out at least a couple of times,
so add a multiplier

The source file uses symbols e.g. execl(), execvp(), _exit(), and so on,
without including unistd.h.
Continuation of 4f18ff2e29.
Follow-up for 9a08000d18.
These source files uses symbols provided by sched.h, e.g.
setns(), unshare(), CLONE_NEWNS, and friends, but they do not explicitly
include sched.h. Currently, it is included indirectly via missing_syscall.h,
which is included by e.g. pidfd-util.h.
Let's explicitly include headers that provides symbols used in the code.
This is similar to 4f18ff2e29, but for sched.h.
- use unsigned for the return value of read_nr_open(), as it does not
fail, and the kernel internally uses unsigned for the value,
- when bumping the value by PID1, let's start from the kernel's maximum
value defined in fs/file.c. The maximum value should be mostly an API
of the kernel, but may changed in a future, hence still try several
times if we fail to bump the value.

SYSTEMD_LANGUAGE_FALLBACK_MAP is used by the localed test, and
language_fallback_map is defined by the localed meson.
If the feature is disabled, the test is not built so the env var
is not needed, and the meson variable is not defined so the build
fails.
Enable nspawn job, as there's no nested kvm so VMs are too slow. Fix
some tests that fail in a VM anyway, might add a nightly job later that
runs them.

chase() is arguably a hot path in our code, hence it deserves
some caching whether open_tree() is available. Moreover,
the manual set of r to -EPERM feels kinda ugly. Let's
instead extract this bit into its own function.
Now that we make use of open_tree() in places we previously used
openat() with O_PATH, it makes sense to move it from @mount to
@file-system. Without the OPEN_TREE_CLONE flag open_tree() is after all
unprivileged.
Note that open_tree_attr() I left in @mount, since it's purpose is
really to set mount options when cloning, and that's clearly a mount
related thing, not so much something you could use unpriv.

This addresses an issue tracked down by Antonio Feijoo: since the commit
that started to use open_tree() various apps started to crash because
they used seccomp filters and sd-device started to use open_tree()
internally.

For initrd presets, we can change the default to disable services
by default instead of enabling by default without breaking compat
so let's do that as it makes much more sense as a default than
enabling everything by default.
