Using fsopen()/fsconfig(), we can check if hidepid/subset are supported to
avoid the noisy logs from the kernel if they aren't supported. This works
on centos/redhat 8 as well since they've backported fsopen()/fsconfig().

Previously, interfaces are partially reconfigured in a spurious way.
Let's use the same way as `networkctl reconfigure`.
Hopefully fixes#14987 and #24997.

Previously, ata_id might not be able to retrieve attributes correctly,
and properties from usb_id were used as a fallback. See issue #24921
and PR #24923. To keep backward compatibility, still we need to create
symlinks based on USB serial.
Fixes#25179.

In https://github.com/containers/podman/issues/16107, starting of a transient
slice unit fails because there's a "global" drop-in
/usr/lib/systemd/user/slice.d/10-oomd-per-slice-defaults.conf (provided by
systemd-oomd-defaults package to install some default oomd policy). This means
that the unit_is_pristine() check fails and starting of the unit is forbidden.
It seems pretty clear to me that dropins at any other level then the unit
should be ignored in this check: we now have multiple layers of drop-ins
(for each level of the cgroup path, and also "global" ones for a specific
unit type). If we install a "global" drop-in, we wouldn't be able to start
any transient units of that type, which seems undesired.
In principle we could reject dropins at the unit level, but I don't think that
is useful. The whole reason for drop-ins is that they are "add ons", and there
isn't any particular reason to disallow them for transient units. It would also
make things harder to implement and describe: one place for drop-ins is good,
but another is bad. (And as a corner case: for instanciated units, a drop-in
in the template would be acceptable, but a instance-specific drop-in bad?)
Thus, $subject.
While at it, adjust the message. All the conditions in unit_is_pristine()
essentially mean that it wasn't loaded (e.g. it might be in an error state),
and that it doesn't have a fragment path (now that drop-ins are acceptable).
If there's a job for it, it necessarilly must have been loaded. If it is
merged into another unit, it also was loaded and found to be an alias.
Based on the discussion in the bugs, it seems that the current message
is far from obvious ;)

Not not IN_SET(…) is just too much for my poor brain. Let's invert

Semi-quoting https://github.com/systemd/systemd/issues/25057:
clang-16 has made the choice to turn on -Werror=implicit-function-declaration,implicit-int.
(See Gentoo's tracker bug https://bugs.gentoo.org/870412).
Added in commit 132c73b57a, systemd now does a
check to see if libatomic is needed with some compile/link tests with e.g.
__atomic_exchange_1, but the tests don't provide a prototype for
__atomic_exchange_1 so with clang-16 the test fails, breaking the build.
Let's simplify things by linking to libatomic unconditionally if it is found
and seems to work. If actually unneeded, it might be dropped via --as-needed.
This seems to work with gcc and clang.
declare_dependency() is used instead of cc.find_library(), because the latter
picks up a symlink in gcc private directory (e.g.
/usr/lib/gcc/x86_64-redhat-linux/12/libatomic.so), and we don't want that.
Fixes#25057.

This fix unfortunately introduced a much worse regression that
is affecting many users, so let's revert it for now and rework
it in the next release.

(cherry picked from commit 0bf1d0ff04)
We would deadlock when passing the data back from the forked-off process that
was doing backtrace generation back to the coredump parent. This is because we
fork the child and wait for it to exit. The child tries to write too much data
to the output pipe, and and after the first 64k blocks on the parent because
the pipe is full. The bug surfaced in Fedora because of a combination of four
factors:
- 87707784c7 was backported to v251.5, which
allowed coredump processing to be successful.
- 1a0281a3eb was NOT backported, so the output
was very verbose.
- Fedora has the ELF package metadata available, so a lot of output can be
generated. Most other distros just don't have the information.
- gnome-calendar crashes and has a bazillion modules and 69596 bytes of output
are generated for it.
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2135778.
The code is changed to try to write data opportunistically. If we get partial
information, that is still logged. In is generally better to log partial
backtrace information than nothing at all.

It is useful to distinguish if json_parse_file() got no input or invalid input.
Use different return codes for the two cases.

Let's document that "." is a bad choice of character when naming
interfaces. Let's also document the hard restrictions we make when

They didn't actually change API between major versions, so let's
support the previous version as well so we can add CentOS 8 Stream
back to CI.

The BUS_DEFINE_PROPERTY_GET_GLOBAL macro requires a value as third
argument, so we need to call manager_is_on_external_power(). Otherwise
the function pointer is interpreted as a boolean and always returns
true:
```
$ busctl get-property org.freedesktop.login1 /org/freedesktop/login1 org.freedesktop.login1.Manager OnExternalPower
b true
$ /lib/systemd/systemd-ac-power --verbose
no

(cherry picked from commit 63168cb517)
PID 1 is not allowed to do nss lookups because this may take a long time or
even deadlock.
While at it, the comparisons are reordered to do the "easy" comparisons which
only require a string comparison first. Delay parsing of the UID until it is
really necessary. The result is the same, because we know that "root" and
"nobody" parse as valid.
(cherry picked from commit 734f96b849)
The very basic functinality of StateDirectory= or friends is creating
specified directories. That should work if one entry is a subdirectory
of another. However, it does not when combined with DynamicUser=yes.
To support such case, this adds ExecDirectoryItem.only_create flag, and
if it is set PID1 only create private directory, and not create the symlink
to the private directory.
Fixes#24783.
(cherry picked from commit a2ab603cc4)
Follow-up for 211a3d87fb.
Previously, although ExecDirectoryItem.symlinks is strv, it always
contains at most one symlink.

Even if a bonding master interface has carrier, the underlying slave
interfaces may not. In such a case, sending solicitation fails with
-ENOBUS. Here, let's unconditionally ignore errors, as anyway we will
send a solicitation later.

In general, log_syntax_internal() must keep errno unchanged. But the

Those may go via the PC speaker, which is annoying and unexpected.
Most people have it off, so this doesn't work reliably anyway, so we can
disable it without much loss.

Before Debian switched to systemd, `shutdown now` would reset the system into
single user mode, doing roughly the equivalent of `telinit 1`.
Now, systemd's `shutdown` command does not behave that way; it defaults to
`poweroff` which might be confusing for users (like me) used to the previous
method.
Because I don't use the command often, I keep being stumped by this behavior,
and every time I look at the `shutdown(1)` manpage, I don't understand why I
can't find what I am looking for. This patch should make sure that people like
me find their way back to some sort of reason.
Maybe the *proper* way to fix this would be to restore the more classic
behavior, but I'm definitely not going to climb that hill. Besides, I clearly
remember the time I found out about the `shutdown` command and was *really*
confused when it brought me back to a command-line prompt. That was really
counter-intuitive and I find that change to actually be a good thing. So I'm
not proposing to change this behavior, merely document it better.
I originally added this to the `-P` option but it was suggested adding a new
`COMPATIBILITY` section instead, where other such issues could be added.
The `COMPATIBILITY` section is not actually officially documented. `man(1)`
talks about a `CONFORMING TO` section, but `shutdown(1)` is not
POSIX (`shutdown(2)` is, of course), so there's no actual standard on how this
should work.
The other option I considered was to add a `BUGS` section, but that seemed to
inflammatory, and definitely counter-productive.

- new symbols are available from libbpf 0.6.0 so could be used with
libbpf.so.0, but we're sure the old symbols will be there and this
simplifies code
- detection at runtime should always work, regardless of whether systemd
has been compiled with older or newer libbpf and runs with older or newer
libbpf
(cherry picked from commit 87e462f713)
libbpf had a soname bump. Our usage of libbpf is compatible with
both libbpf.so.0 and libbpf.so.1, so let's try to load from both.
(cherry picked from commit 5a967e2887)
Currently, even if `--discard=no` is passed to `systemd-repart`, the
`context_discard_gap_after()` function still runs normally, discarding
e.g. all blocks between the GPT and the start of the first partition.
This can lead to issues on some embedded devices, where this space
holds the bootloader and shouldn't be modified (creating a protective
partition there is not always possible due to the specifics of the boot
process of some ARM-based SoC's).
This commit ensures passing `--discard=no` would be enough to ensure
the bootloader isn't wiped in such cases.

This is useful for systems which don't have any fsck.
We already skip emitting the fsck dependency when the fsck.$fstype helper
is missing, but fstab-generator doesn't necessarily know the fstype when
handling the root= parameter.
Previously, systemd-fsck was started for these mounts and then exited
immediately because it couldn't find the fsck.$fstype helper.
