It is extremely confusing to use different filenames for different
locations, so pick up the same images for both per-UKI and global

Previously, when the stdout of a spawned process (e.g. dmi_memory_id) is
truncated, the event source was not re-enabled, that will cause the process
to remain in a write-blocked state if the stdout buffer is full, and the
process will time out:
```
Spawned process 'dmi_memory_id' [1116] timed out after 2min 59s, killing.
Process 'dmi_memory_id' terminated by signal KILL.
```
The solution is to continue enabling the event source so that on_spawn_io()
can continue reading the stdout buffer. When the result buffer is full, the
local `buf` variable will be used to drain remaining stdout.

E.g. dns_question_contains_key() may return negative errno, hence we
should not use ASSERT_TRUE/FALSE() for the function.
This also has bunch of cleanups:
- call functions in ASSERT_NOT_NULL(),
- add short comments for constant function arguments,
- merge several test cases,
- use memstream, rather than temporal files.
Fixes CID#1619185.
E.g. dns_answer_match_key() may return negative errno, hence we should

Previously we didn't provide any install_callback to
sd_bus_add_match_async() so in case AddMatch() method call timed out we
destroyed the bus connection. This seems overly aggressive and simply
updating the sd_bus_track object accordingly should be enough.

When booting Linux with ACPI in QEMU, the device tree is not used and
the DT based detection will not work. DMI values are accurate though
and indicate QEMU.
While detect_vm_dmi_vendor() was enabled for RISC-V in a previous commit,
it missed detect_vm_dmi(), so it was never actually used. Fix that.

It is not easy to understand what happens to a journal file
even with debug logs enabled. Add more dbg messages around operations
started by users to make it possible to follow the flow of operations.
If the removal of the devlink is requested due to this is a 'remove' event,
it is trivial that the devlink will not be owned by this device anymore.
Let's read the devlink and if it points to our device node, then we need
to update the devlink. If it points to another device node, then it is already
owned by another device, hence we should not touch it and keep it as is.
Fixes#37823.
Fix regression introduced in a7bfb9f76b,
where busy loop can be started with a request for following logs with a
range header set with num_skip value pointing beyond the end of the
journal. In that case the reader callback returns 0 and is called
immediately again, usually causing an endless loop that is not recovered
even when new journal events are added.
The bug does not occur if num_skip is not set - in that case if no
journal entries matching the filters are added, the tight loop is
avoided by the sd_journal_wait().
To fix the issue, when no matching journal events are available, set a
flag and reuse the backoff mechanism using the sd_journal_wait().

As prompted by #38393, search domains may be large when a complicated
network setting is used, especially when VPN is used. Let's bump the
limit to 1024.
Note, this does not bump the maximum number of DNS servers, as setting
thousands of DNS servers is spurious and mostly meaningless. Let's keep
the maximum for a while until someone requests to also bump them.

Closes#38393.
As discussed in https://github.com/systemd/systemd/issues/38399, "ordinary"
systems can have the field table with a large number of values, causing journal
rotation to occur early. For example, audit generates a log of fields:
$ journalctl --fields | rg -c '^_?AUDIT'
114
It seems that the "structured log" capabilities of the journal are being use
more than in the past. Looking at some journal files on my system, it seems
the field hash table field is quite high in many cases:

Since filling of the field hash table to 75% normally causes file rotation,
let's double the default to make rotation happen less often.
We'll use 11kB more for the hash table, which should be fine, considering
that journal files are usually at least 8 MB.
Closes https://github.com/systemd/systemd/issues/38399.
It's easier to think about the size in "objects", not bytes. Let's convert to
bytes at the last moment.
Also drop some of the pointless size suffixes. In general, it's the size of the
variable that matters, not the constant that is written to it.
No functional change.
drained() checks PTYForward.master_readable flag, but it may be
tentatively unset due to a tentative error like EAGAIN in the previous
IO event. Let's try to call shovel() one more time, which re-read the
master and call drained() at the end. Otherwise, we may lost some data.
When PTYForward.done is set, the PTYForward.master is already
disconnected. Let's not try to read the already closed file descriptor.
Also, if we previously received vhangup, then it is not necessary to
re-read the device to check vhangup, as we already know.
This also make the check slightly delayed, and use a defer event source,
to make the function can be called safely in another event source.
Currently, pty_forward_set_ignore_vhangup() is only used for disabling
the flag. To make the function also disable PTY_FORWARD_IGNORE_INITIAL_VHANGUP
flag, this renames it to pty_forward_honor_vhangup().
Also, for consistency, pty_forward_get_ignore_vhangup() and
ignore_vhangup() are replaced with pty_forward_vhangup_honored().
Previously, do_shovel() sometimes call pty_forward_done(), and
its caller shovel() also call pty_forward_done(). Let's move all
pty_forward_done() calls to shovel(), and do_shovel() not call it.
No functional change, just refactoring.
We had errno_to_name() which works for "known" errnos, and returns NULL for
unknown ones, and then ERRNO_NAME which always returns an answer, possibly just
a number as a string, but requires a helper buffer.
It is possible for the kernel to add a new errno. We recently learned that some
architectures define custom errno names. Or for some function to unexpectedly
return a bogus errno value. In almost all cases it's better to print that value
rather than "n/a" or "(null)". So let's use ERRNO_NAME is most error handling
code. Noteably, our code wasn't very good in handling the potential NULL, so
in various places we could print "(null)". Since this is supposed to be used
most of the time, let's shorten the names to ERRNO_NAME/errno_name.
There are a few places where we don't want to use the fallback path, in
particular for D-Bus error names or when saving the error name. Let's rename
errno_to_name() to errno_name_no_fallback() to make the distinction clearer.

For whatever reason, ly is setting $XDG_RUNTIME_DIR before invoking
PAM session on its own
(https://github.com/fairyglade/ly/blob/v1.1.1/src/auth.zig#L45),
which after the offending commit will potentially be unset again
by pam_systemd. Let's restore the previous behavior if not switching area.
Fixes#38402
The usual pattern of using colors to distinguish the mount path (/efi/)
and the rest is used. If the file cannot be read for reasons other than
-ENOENT, the error message is highlighted.
I considered a few places where to add this, but this section seems the
most reaosonable. We already print the 'token' there, which is also part of
the configuration.

With the previous commit, now CHASE_MUST_BE_DIRECTORY can be set with
CHASE_NONEXISTENT. Let's unconditionally set the flag to chase the
directory part of the conf file.
Otherwise, if it is called with CHASE_NONEXISTENT, when we call
stat_verify_directory()/_regular() the struct stat is for one of the
parent directory, rather than for the result path.
With this change, we can safely specify CHASE_MUST_BE_DIRECTORY/REGULAR
with CHASE_NONEXISTENT.
More importantly, chaseat() internally sets CHASE_MUST_BE_DIRECTORY when
the input path ends with "/", "/,", "/..". Hence, without this change,
we cannot specify CHASE_NONEXISTENT safely.
