e88748c17e sysctl: add --strict option to fail if sysctl does not exists
systemd-sysctl currently fails silently under any of these conditions:
- Missing permission to write a sysctl.
- Invalid sysctl (path doesn't exists).
- Ignore failure flag ('-' in front of the sysctl name).

Because of this behaviour, configuration issues can go unnoticed as
there is no way to detect those unless going through the logs.

--strict option forces systemd-sysctl to fail if a sysctl is invalid or
if permission are insufficient. Errors on sysctl marked as "ignore
failure" will still be ignored.

0ad7b7b809 man: Use correct target type for sysupdate entry
While Type=file works because it seems to be the default, the line gets
ignored as printed on the stderr output.
Use the correct value "regular-file" for the target type.

519c2f0d6b man: Document mask workaround for sysext images
A read-only /usr may ship a sysext image by default and the user wants
to opt out. Currently it's not clear how to do this.
Document that a /dev/null symlink in /etc/extensions/ works to "mask" a
sysext image in a folder with lower precedence.

566e4b3a19 man: Do not recommend to overlay files with sysext even if possible
While overlaying files with a sysext can be useful, it may lead to
unexpected problems depending on when a process got started and which
version of the file it gets.
Call out that overlaying files is possible but don't recommend to make
use of it.

50ee1fec3a network: dhcp6: re-introduce RapidCommit= setting
Previous implementation of disabling rapid commit was broken, and
dropped by 308d01f3c4.

Let's re-introduce the option in the correct way, as some servers seem
to return borked message when the solicit message contain the rapid
commit option.

Closes #24065.

23e9a7dde5 core: cache unit file selinux label, and make decisions based on that
Do not go back to disk on each selinux access, but instead cache the
label off the inode we are actually reading. That way unit file contents
and unit file label we use for access checks are always in sync.

Based on discussions here:

https://github.com/systemd/systemd/pull/10023#issuecomment-1179835586

Replaces:

https://github.com/systemd/systemd/pull/23910

This changes behaviour a bit, because we'll reach and cache the label at
the moment of loading the unit (i.e. usually on boot and reload), but
not after relabelling. Thus, users must refresh the cache explicitly via
a "systemctl daemon-reload" if they relabelled things.

This makes the SELinux story a bit more debuggable, as it adds an
AccessSELinuxContext bus property to units that will report the label we are
using for a unit (or the empty string if not known).

This also drops using the "source" path of a unit as label source. if
there's value in it, then generators should manually copy the selinux
label from the source files onto the generated unit files, so that the
rule that "access labels are read when we read the definition files" is
upheld. But I am not convinced this is really a necessary, good idea.

91ea7ebcdf sleep: store battery discharge rate/hour with hash
Estimated battery discharge rate per hour is stored in :
/var/lib/systemd/sleep/battery_discharge_percentage_rate_per_hour

This value is used to determine the initial suspend interval. In case
this file is not available or value is invalid, HibernateDelaySec
interval is used.
After wakeup from initial suspend, this value is again estimated and
written to file if value is in range of 1-199.

34aee208b5 man/system-or-user-ns.xml: explicitly refer to PrivateUsers= option
It is not clear what "unprivileged user namespaces are available" means.
It could mean either that they are only usable, that is, enabled in the kernel,
or they have been enabled for the specific service. Referring to the
`PrivateUsers=` options makes it clear that the latter is meant.

17021368fc generators: accept one or three args, do not write to /tmp
Since the general generator logic was established in the rewrite in
07719a21b6, generators would always write to /tmp
by default. I think this not a good default at all, because generators write a
bunch of files and would create a mess in /tmp. And for debugging, one
generally needs to remove all the files in the output directory, because
generators will complain in the output paths are already present. Thus the
approach of disabling console logging and writing many files to /tmp when
invoked with no arguments is not nice, so let's disallow operation with no
args.

But when debugging, one generally does not care about the separate output dirs
(most generators use only one). Thus the general pattern I use is something
like:
  rm -rf /tmp/x && mkdir /tmp/x && build/some-generator /tmp/{x,x,x}
This commit allows only one directory to be specified and simplifies this to:
  rm -rf /tmp/x && mkdir /tmp/x && build/some-generator /tmp/x

8de7de462b pid1: import creds from SMBIOS too, not just qemu's fw_cfg
This imports credentials also via SMBIOS' "OEM vendor string" section,
similar to the existing import logic from fw_cfg.

Functionality-wise this is very similar to the existing fw_cfg logic,
both of which are easily settable on the qemu command line.

Pros and cons of each:

SMBIOS OEM vendor strings:
   - pro: fast, because memory mapped
   - pro: somewhat VMM independent, at least in theory
   - pro: qemu upstream sees this as the future
   - pro: no additional kernel module needed
   - con: strings only, thus binary data is base64 encoded

fw_cfg:
   - pro: has been supported for longer in qemu
   - pro: supports binary data
   - con: slow, because IO port based
   - con: only qemu
   - con: requires qemu_fw_cfg.ko kernel module
   - con: qemu upstream sees this as legacy

aa5ae9711e smack: Add DefaultSmackProcessLabel to user.conf and system.conf
DefaultSmackProcessLabel tells systemd what label to assign to its child
process in case SmackProcessLabel is not set in the service file. By
default, when DefaultSmackProcessLabel is not set child processes inherit
label from systemd.

If DefaultSmackProcessLabel is set to "/" (which is an invalid character
for a SMACK label) the DEFAULT_SMACK_PROCESS_LABEL set during compilation
is ignored and systemd act as if the option was unset.
