Yu Watanabe 543a48b653 libc-wrapper: introduce a tiny libc wrapper
Then, move syscall definitions to the wrapper, and prototypes are moved
to relevant headers.

This also adds checks for add_key() and request_key(), as one day
glibc may be going to add some of them separatedly.

The check for fspick in meson.build is dropped, as it is currently
unused in our code.

This also moves
- basic/missing_bpf.h -> include/override/linux/bpf.h,
- basic/missing_keyctl.h -> include/override/linux/keyctl.h.

Yu Watanabe fbf6836812 tree-wide: include missing_fs.h only where necessary
The additional definitions provided by the header are
- EXT4_IOC_RESIZE_FS, used in resize-fs.c,
- FILEID_KERNFS, used in cgroup-util.c and pidfd-util.c.

Let's drop the inclusion at other places.

Yu Watanabe 2a5f950e56 glob-util: rework safe_glob()
Currently, callers of safe_glob() set an empty glob_t or glob_t with
opendir func, and all other components are always zero.
So, let's introduce safe_glob_full() which optionally takes opendir
function, rather than glob_t, and returns result strv, rather than
storing results in glob_t.
Also, introduce safe_glob() which is a trivial wrapper of
safe_glob_full() without opendir func.

No functional change, just refactoring.

Lennart Poettering ee8e7000f2 tmpfiles: fix symlink creation when replacing
When we remove an existing inode in order to create a symlink we need to
create the symlink via a pinned directory again, instead of using an
absolute path, otherwise this will not work in the --root= case.

Let's fix this, and switch this over to symlinkat_atomic_full().

Lennart Poettering 9ea5a6e7d6 fs-util: replace symlink_atomic_full_label() by a flag to symlinkat_atomic_full()
More porting work to label_ops_pre()/label_ops_post()

This also enables labelling of the /etc/localtime symlink in
systemd-firstboot, which should address one small facet of #37857

Daan De Meyer f1ee656d4d tree-wide: Handle EINVAL as not supported for chattr_xxx()
F2FS returns EINVAL from FS_IOC_SETFLAGS when trying to set
FS_NOCOW_FL. Let's handle this by treating EINVAL as not supported.
While we're at it, make sure we use ERRNO_IS_IOCTL_NOT_SUPPORTED()
across the tree instead of ERRNO_IS_NOT_SUPPORTED() when calling any
of the chattr_xxx() functions.

Fixes #37593

Daan De Meyer 1971631294 meson: Don't define targets for standalone binaries if option is not enabled
These are built from the same sources as the regular binaries, so we
end up with the same sources multiple times in the compilation database
but with different command line arguments, which trips up tooling that
uses the compilation database. Let's not define the standalone targets if
the option is not enabled to avoid this problem.

Daan De Meyer a583b34416 meson: Extract more objects instead of compiling multiple times
Also, let's deflatten the lists of sources in preparation for the
next commit at the same time.

In systemctl, we split out systemctl-main.c to make sure the definition
of main() is in a separate object which allows us to extract the systemctl.c
object and link it in the fuzzer target without getting a multiple definition
error when linking.

Daan De Meyer 8857aa74e5 tree-wide: Clean up includes
This commit cleans up the includes for all the small tools across

A few cases of returning EXIT_SUCCESS are replaced with returning
0 to avoid including <stdlib.h>.

Split out of #37344.

Daan De Meyer 6350d2dbd9 meson: Extract objects instead of creating intermediate static libraries
Currently, when we want to add unit tests for code that is compiled into
an executable, we either compile the code at least twice (once for the
executable, and once for each test that uses it) or we create a static
library which is then used by both the executable and all the tests.

Both of these options are not ideal, compiling source files more than
once slows down the build for no reason and creating the intermediate
static libraries takes a lot of boilerplate.

Instead, let's use the extract_objects() method that meson exposes on
build targets. This allows us to extract the objects corresponding to
specific source files and use them in other executables. Because we
define all executables upfront into a dictionary, we integrate this into
the dictionary approach by adding two new fields:

- 'extract' takes a list of files for which objects should be extracted.
  The extracted objects are stored in a dict keyed by the executable name
  from which they were extracted.
- 'objects' takes the name of an executable from which the extracted
  objects should be added to the current executable.

One side effect of this approach is that we can't build test executables
anymore without building the main executable, so we stop building test
executables unless we're also building the main executable. This allows
us to switch to using subdir_done() in all of these subdirectories to skip
parsing them if the corresponding component is disabled.

These changes get me down from 2439 => 2403 ninja targets on a full rebuild
from scratch.

Daan De Meyer 93a1f7921a basic: Stop including log.h in macro.h
Now that the necessary functions from log.h have been moved to macro.h,

files all over the tree to include log.h instead.

Zbigniew Jędrzejewski-Szmek 1ae9b0cfa8 basic/glyph-util: rename "special glyph" to just "glyph"
Admittedly, some of our glyphs _are_ special, e.g. "O=" for SPECIAL_GLYPH_TOUCH ;)
But we don't need this in the name. The very long names make some invocations
very wordy, e.g. special_glyph(SPECIAL_GLYPH_SLIGHTLY_UNHAPPY_SMILEY).
Also, I want to add GLYPH_SPACE, which is not special at all.

Yu Watanabe ec32732043 basic: introduce our own sys/mount.h implementation
To resolve conflict with sys/mount.h and linux/mount.h or linux/fs.h.

The conflict between sys/mount.h and linux/mount.h is resolved in
glibc-2.37 (774058d72942249f71d74e7f2b639f77184160a6), but our baseline
is still glibc-2.31. Also, even with the version or newer, still
sys/mount.h conflicts with linux/fs.h, which is included by
linux/btrfs.h.

This introduces our own implementation of sys/mount.h, that can be
simultaneously included with linux/mount.h and linux/fs.h. This also
imports linux/fs.h, linux/mount.h, and several other dependent headers.
The introduced sys/mount.h header itself may not be enough simple, but
by using the header, we can drop most of workarounds in other source files.

Daan De Meyer daa2547e31 Add a few more bypass environment variables
When we're building ParticleOS images, we don't want the package
manager (or mkosi) to run systemd-sysusers, systemd-tmpfiles or
systemctl preset so let's add a few more bypass environment
variables that we can set to have execution of these skipped like
we already have $SYSTEMD_HWDB_UPDATE_BYPASS and $KERNEL_INSTALL_BYPASS.

Yu Watanabe d5ddc0e0d3 stat-util: drop statx_fallback()

2025-03-01 00:33:32 +09:00
Yu Watanabe 4424e6c811 tree-wide: drop workarounds for statx()
struct statx in glibc header was introduced in glibc-2.28
(fd70af45528d59a00eb3190ef6706cb299488fcd), but at that time,
sys/stat.h conflicts with linux/stat.h. Since glibc-2.30
(5dad6ffbb2b76215cfcd38c3001778536ada8e8a), sys/stat.h includes
linux/stat.h if exists.

Since now our baseline of glibc is 2.31. Hence, we can drop workarounds
for struct statx by importing linux/stat.h from newer kernel (v6.14-rc4).

Zbigniew Jędrzejewski-Szmek 390bab5392 tmpfiles: reduce quoting in warning message
We printed:
systemd-tmpfiles[705]: /usr/lib/tmpfiles.d/20-systemd-shell-extra.conf:10: Unknown modifiers in command 'L$'.
systemd-tmpfiles[705]: /usr/lib/tmpfiles.d/systemd-network.conf:10: Unknown modifiers in command 'd$'.
systemd-tmpfiles[705]: /usr/lib/tmpfiles.d/systemd-network.conf:11: Unknown modifiers in command 'd$'.
...

There's a lot of additional characters here make the message harder to parse. We know
that the command is a word without any whitespace, so quoting isn't really necessary.

Change this to:
... unknown modifiers in command: L$

Mike Yuan 1f8eedba9d path-lookup: introduce user_search_dirs() (shall replace xdg_user_dirs())
xdg_user_dirs() doesn't seem well-organized currently.
In all other xdg_user_*() funcs we assume /etc/xdg/systemd
to be a symlink to /etc/systemd/, hence it is the odd one out.
Also, when the relevant envvar is unset, it only returns
the global search dirs.

sd_path_lookup() actually covers this nicely with SD_PATH_SEARCH_*,
where the combined search paths (from user home and system) are used.
Therefore, let's introduce a wrapper for that, and deprecate xdg_user_dirs()
(would be removed in later commits).
