This takes inspiration from AT_FDCWD, but always references the root dir
rather than the cwd. This allows various convenience uses, as we can now
reference the root dir without actually allocating an fd for chaseat(),
fd_get_path() and various others.
The value of XAT_FDROOT is chosen so that it is not a valid fd (essential,
because we do not intend to hook this up everywhere, just where we need
it, just like AT_FCWD only works in some syscalls), and we want uses at
the wrong places to fail cleanly. It also uses a valud outside of the
range where we usually return negative errnos, i.e. < -ERRNO_MAX.
Various socktops will fail if we run in a container, due to lack of
privs (for example SO_RECVFORCE as used by the journald sockets). That's
typically not a big issue. Hence downgrade the log level.

This also makes 70-lights.hwdb installed. The file was introduced by
106f64cbd6, but never installed.
Moreover, this makes the parser also check bluetooth modalias patterns.
This is a small followup for
https://github.com/systemd/systemd/pull/40344#discussion_r2695031041
(thanks Daan and Lennart!).
There are quite a few places in the code that currently log a
`log_error()` when a `log_warning()` is more appropriate because
the error is ignored. This commit now shows those as warnings.
RootImageOptions=/ExtensionImages=/MountImages= all support custom
mount options, but mountfsd does not support it. Add varlink
parameters to allow callers to specify mount options so that
those directives can work as expected. Require additional privs via
polkit.
Add a test case to verify that cat_files() correctly handles symlinks
to /dev/null (masked configuration files) and returns success (0)
instead of failing.
This test complements the fix for issue #40313.

Before 661b5bfd21, cat_files() does not
check if a file is regular. If the file is a symlink to /dev/null, then
cat_files() simply shows an empty contents for the file.
With the offending commit, as the CHASE_MUST_BE_REGULAR flag is set,
hence when we found a masked file, the function fails.
Fixes#40313.
Fixes regression caused by 661b5bfd21.

Previously, when `systemctl reload-or-restart --marked` failed the following
error was shown:
Failed to start jobs: Failed to enqueue some jobs, see logs for details: Invalid argument
but no details were actually logged.
This change records failure reasons in the journal to help users identify root causes:
# journalctl -b -e
[...]
systemd[1]: Queuing reload/restart jobs for marked units…
systemd[1]: Operation refused, unit klogd.service may be requested by dependency only (it is configured to refuse manual start/stop).
This is in preparation for later changes. The 1500+ line switch statement was very
hard to work with and had quite a bit of duplicated code. This is a rework that
splits outs parts into functions. I split this up into a bunch of commits so that it
can be reasonably reviewed. When viewed as one giant commit, diff just shows
a giant block of removed code and a giant block of added code.
In some cases I wasn't sure why one or the other of the identity arrays is used…
I preserved existing behaviour in all cases.
Currently, pick_filter_image_any matches any image
with any suffix, which is way more than it should
be doing. It should only be matching images with
the .raw suffix.
Let's address this shortcoming by allowing to pass
multiple filters to path_pick(), and define
pick_filter_image_any as the combination of the
raw and directory image filters.
Fixes#40083
Allow configuring the menu timeout used by sd-boot by setting
`io.systemd.boot.timeout=<value>` as SMBIOS type 11 string.
This takes precedence over the setting from the config file
and the EFI var.
Useful for e.g. integration tests that want to control that
a generic image boots faster.
When employing MCL_FUTURE we don't actually want it to impose
immediate population of malloc()-ed pages. Hence let's set
MCL_ONFAULT everywhere.
Additionally, specify MCL_CURRENT to ensure future memory allocations
on already mapped pages are covered too. (Addresses
https://github.com/systemd/systemd/pull/40319#discussion_r2693726196)
Note that in shutdown the mlockall() is done to avoid keeping swap space
busy, hence a dedicated call w/ MCL_CURRENT and w/o MCL_ONFAULT is made.
If no real jobs were added to the transaction, do not activate it.
The JOB_NOP anchor does not perform any useful work and activating
such transaction only wastes resources.
Fixes#9751
The systemd-vmspawn man page has a note that the `--notify-ready`
defaults to "true" and then says that this is unlike "systemd-vmspawn"
where it defaults to "false". This appears to be a copy/paste issue
and here we want "unlike systemd-nspawn".
