them with the existing --quiet flag if desired. Makes systemd-analyze

elf-util: discard PT_LOAD segment early based on the start address.
Indeed when iterating over all the PT_LOAD segment of the core dump
while trying to look for the elf headers of a given module, we iterate
over them all and try to use the first one for which we can parse a
package metadata, but the start address is never taken into account,
so absolutely nothing guarantees we actually parse the right ELF header
of the right module we are currently iterating on.
This was tested like this:
- Create a core dump using sleep on a fedora 37 container, with an
explicit LD_PRELOAD of a library having a valid package metadata:
- Then from a fedora 38 container with systemd installed, the resulting
core dump has been passed to systemd-coredump with and without this
patch. Without this patch, we get:
Module /usr/bin/sleep from rpm bash-5.2.15-3.fc38.x86_64
Module /usr/lib64/libtinfo.so.6.3 from rpm coreutils-9.1-8.fc37.x86_64
Module /usr/lib64/libc.so.6 from rpm coreutils-9.1-8.fc37.x86_64
Module /usr/lib64/libreadline.so.8.2 from rpm coreutils-9.1-8.fc37.x86_64
Module /usr/lib64/ld-linux-x86-64.so.2 from rpm coreutils-9.1-8.fc37.x86_64
While with this patch we get:
Module /usr/bin/sleep from rpm bash-5.2.15-3.fc38.x86_64
Module /usr/lib64/libtinfo.so.6.3 from rpm ncurses-6.3-5.20220501.fc37.x86_64
Module /usr/lib64/libreadline.so.8.2 from rpm readline-8.2-2.fc37.x86_64
So the parsed package metadata reported by systemd-coredump when the module
files are not found on the host (ie the case of crash inside a container) are
now correct. The inconsistency of the first module in the above example
(sleep is indeed not provided by the bash package) can be ignored as it
is a consequence of how this was tested.
In addition to this, this also fixes the performance issue of
systemd-coredump in case of the crashing process uses a large number of
shared libraries and having no package metadata, as reported in
https://sourceware.org/pipermail/elfutils-devel/2023q2/006225.html.

core: Add RootEphemeral= setting
This setting allows services to run in an ephemeral copy of the root
directory or root image. To make sure the ephemeral copies are always
cleaned up, we add a tmpfiles snippet to unconditionally clean up
/var/lib/systemd/ephemeral. To prevent in use ephemeral copies from
being cleaned up by tmpfiles, we use the newly added COPY_LOCK_BSD
and BTRFS_SNAPSHOT_LOCK_BSD flags to take a BSD lock on the ephemeral
copies which instruct tmpfiles to not touch those ephemeral copies as
long as the BSD lock is held.
It's highly interesting to see if tools such as systemd-sysupdate
consider a version valid, hence let's output that too (though
gracefully, not fatally)
string-util: move version_is_valid() into generic code
While we are at it, replace the sloppy use of filename_is_valid() by the
less sloppy filename_part_is_valid() (as added by the preceeding
commit), since we don#t want to be too restrictive here. (After all,
version strings invalid as standalone filenames might be valid as part
of filenames, and hence we should allow them).
Add a helper filename_part_is_valid() which does half of what
filename_is_valid() does: it checks for valid chars and length, but does
not filter out ".", ".." and "", as these are OK as parts of filenames,
just not alone.
hostnamectl: show age of firmware as time span, too
This converts the date into a relative timespan from the current time
on, and outputs it. It marks it yellow if older than two years, since
old firmware is probably a security risk. We don't make it red, since we
don't know though.

namespace: Load sidecar verity settings in apply_mount_namespace()
Let's reduce the argument count of setup_namespace() a bit by loading
the sidecar verity settings in apply_mount_namespace(). This will also
make it possible to pass file descriptors to the root image/directory
into setup_namespace() as before this wasn't possible because the
verity settings logic looks for sidecar files next to the
root image which requires the path to be available.
hostnamed: when parsing day/month of firmware date, force decimal parsing
safe_atou() by default determines the base from the prefix 0x, 0b, 0o
and for compat with just 0 for octal. This is not what we want here,
since the date components are padded with zeroes yet still decimal.
Hence force decimal parsing (and while we are at it, prohibit a couple
of unexpected decorations).
WIthout this we'd fail to parse any the 8th and 9th day of each months, as
well aus aug and september of every year, because these look like octal
numbers but cannot actually parsed as such.
Let's change the testcase to check for a date that exposes this
bheaviour.
rules: split out DMI related rules from udev-default.rules
The DMI rules where so far guarded by an ACTION=="add" rule, but that
doesn't really make sense for setting properties (only for setting
access modes/ownership of nodes).
Hence let's move this into its own file, that guards properly on
ACTION!="remove".
Before this change the hardware vendor/model info would be dropped
whenever the device was retriggered.
The file long ceased to be exclusively about configuration of the sleep
operation. It contains many many calls for other purposes, hence give it
a more generic name.
sleep-config: reduce scope of DMI object path a bit
We need this in a single function only, hence move it there, and make it
a static field so that it has local scope.
While we are at it, rename s/readsize to buf/bufsize, to make
relationship clear. In particular as the data read is actually binary
and "s" hence a misnomer, since it suggests it was a string.

btrfs-util: Add BTRFS_SNAPSHOT_LOCK_BSD
When making ephemeral snapshots of subvolumes whose cleanup depends on
whether they're locked or not, it's necessary to have the lock from the
very beginning, so let's support that with a new BTRFS_SNAPSHOT_LOCK_BSD
flag.
This has been badly named given the path doesn't refer to a device quite
likely, but to a path to a regular file. Hence let's be more precise
with naming.
(.device kinda suggests this was an sd_device object of sorts, but it
really isn't.)
sleep-config: don't use 'device_id' moniker for a dev_t entity
We usually call dev_t entities "devnum" or "devno". That's redundant
enough, let's not call this "device_id". In particular as that's
something else (in udev context).
sleep-config: replace useless fstat() by useful fd_verify_regular()
For some reason there was an fstat() call here whose results was
entirely ignored. Let's remove it. Let's add a call to
fd_verify_regular() instead, because this is a code path for swap files,
hence let's make sure we actually operate on a file, and nothing else.

MHD_OPTION_EXTERNAL_LOGGER is not the first option specified for

This change is incorrect as we don't want to mark the PID as invalid but
only mark it as dead.
The change in question also breaks user level socket activation for
`podman.service` as the termination of the main `podman system service`
process is not properly handled, causing any application accessing the
socket to hang.
This is because the user-level `podman.service` unit also hosts two
non-main processes: `rootlessport` and `rootlessport-child` which causes
the `cgroup_good` check to still succeed.

more correct way to fix the cgroupsv1 issue on CentOS 8.

EFI_DEVICE_PATH_FROM_TEXT_PROTOCOL, which yielded an identical device
