Subject: [PATCH] meson: do not compare objects of different types
This fixes the following warning:
```
meson.build:1140: WARNING: Trying to compare values of different types (DependencyHolder, list) using !=.
The result of this is undefined and will become a hard error in a future Meson release.
```
Follow-up for f02582f69fe1e7663a87ba80bd4f90d5d23ee75f(#9410).

Subject: [PATCH] ci: replace LGTM with CodeQL
As LGTM is going to be shut down by EOY, let's use CodeQL instead.
This is loosely based on upstream's CodeQL configs with some minor
tweaks to avoid backporting tons of unrelated commits.

Subject: [PATCH] basic: recognize pdfs filesystem as a network filesystem
Fujitsu advises their users to always use _netdev mount option with pdfs
mounts. Hence it makes sense to simply consider pdfs mounts as network
filesystem mounts.

Subject: [PATCH] core: move reset_arguments() to the end of main's finish
Fixes #16991
fb39af4ce42d7ef9af63009f271f404038703704 replaced `free_arguments()` with
`reset_arguments()`, which frees arg_* variables as before, but also resets all
of them to the default values. `reset_arguments()` was positioned
in such a way that it overrode some arg_* values still in use at shutdown.
To avoid further unintentional resets, I moved `reset_arguments()`
right before the return, when nothing else will be using the arg_* variables.

Subject: [PATCH] sysctl: downgrade message when we have no permission
We need to run sysctl also in containers, because the network
subtree is namespaces and may legitimately be writable. But logging
all "errors" at notice level creates unwanted noise.
Also downgrade message about missing sysctls to log_info. This might also be
relatively common when configuration is targeted at different kernel
versions. With log_debug it'll still end up in the logs, but isn't really worth
of "notice" most of the time.

normally have the same label as the owning process).

Subject: [PATCH] manager: use target process context to set socket context
Use target process context to set socket context when using SELinuxContextFromNet
not systemd's context. Currently when using the SELinuxContextFromNet option for
a socket activated services, systemd calls getcon_raw which returns init_t and
uses the resulting context to compute the context to be passed to the
setsockcreatecon call. A socket of type init_t is created and listened on and
this means that SELinux policy cannot be written to control which processes
(SELinux types) can connect to the socket since the ref policy allows all
'types' to connect to sockets of the type init_t. When security accessors see
that any process can connect to a socket this raises serious concerns. I have
spoken with SELinux contributors in person and on the mailing list and the
consensus is that the best solution is to use the target executables context
when computing the sockets context in all cases.
[zjs review/comment:
This removes the branch that was added in 16115b0a7b7cdf08fb38084d857d572d8a9088dc.
16115b0a7b7cdf08fb38084d857d572d8a9088dc did two things: it had the branch here
in 'socket_determine_selinux_label()' and a code in 'exec_child()' to call
'label_get_child_mls_label(socket_fd, command->path, &label)'.
Before this patch, the flow was:
'''
mac_selinux_get_child_mls_label:
peercon = getpeercon_raw(socket_fd);
if (!exec_label)
exec_label = getfilecon_raw(exe);
socket_open_fds:
if (params->selinux_context_net) #
label = mac_selinux_get_our_label(); # this part is removed
else #
label = mac_selinux_get_create_label_from_exe(path);
socket_address_listen_in_cgroup(s, &p->address, label);
exec_child():
exec_context = mac_selinux_get_child_mls_label(fd, executable, context->selinux_context);
setexeccon(exec_context);
'''

Subject: [PATCH] virt: detect Amazon EC2 Nitro instance
Amazon EC2 Nitro hypervisor is technically based on KVM[1], which
systemd-detect-virt identify propely from CPUID. However the lack of
CPUID on aarch64 (A1, T4 instance type) prevents a correct
identification, impacting hostnamectl and systemd-random-seed. Instead
it's possible to identify virtualization from DMI vendor ID.
Prior to this commit:
# hostnamectl
Static hostname: n/a
Transient hostname: ip-10-97-8-12
Icon name: computer
Machine ID: 8e3772fbcfa3dd6f330a12ff5df5a63b

Operating System: Gentoo/Linux
Kernel: Linux 5.4.69-longterm
Architecture: arm64
After this commit:
# hostnamectl

Subject: [PATCH] fileio: introduce read_full_virtual_file() for reading
virtual files in sysfs, procfs
Virtual filesystems such as sysfs or procfs use kernfs, and kernfs can work
with two sorts of virtual files.
One sort uses "seq_file", and the results of the first read are buffered for
the second read. The other sort uses "raw" reads which always go direct to the
device.
In the later case, the content of the virtual file must be retrieved with a
single read otherwise subsequent read might get the new value instead of
finding EOF immediately. That's the reason why the usage of fread(3) is
prohibited in this case as it always performs a second call to read(2) looking
for EOF which is subject to the race described previously.
Fixes: #13585.

Subject: [PATCH] Use BIOS characteristics to distinguish EC2 bare-metal from
VMs
DMI vendor information fields do not provide enough information for us to
distinguish between Amazon EC2 virtual machines and bare-metal instances.
SMBIOS provides a BIOS Information
table (https://www.dmtf.org/sites/default/files/standards/documents/DSP0134_3.4.0.pdf
Ch. 7) that provides a field to indicate that the current machine is a virtual
machine. On EC2 virtual machine instances, this field is set, while bare-metal
instances leave this unset, so we inspect the field via the kernel's
/sys/firemware/dmi/entries interface.
Fixes #18929

Subject: [PATCH] manager: limit access to private dbus socket
For the system manager, /run/systemd/private is publicly accessible, because
/run/systemd is 0755, and /run/systemd/private is 0777. For the user manager,
/run/user/<uid> is 0700, and /run/user/<uid>/systemd/private is 0777. This
does not directly cause any security issue because we check the sender in
bus_check_peercred (ucred.uid != 0 && ucred.uid != geteuid()).
But it makes sense to limit access to the socket to avoid wasting time in PID1.
Somebody could send messages there that'd we'd reject anyway. It also makes
things more explicit.

Subject: [PATCH] core: bring manager_startup() and manager_reload() more
inline
Both functions do partly the same, let's make sure they do it in the
same order, and that we don't miss some calls.
This makes a number of changes:
1. Moves exec_runtime_vacuum() two calls down in manager_startup(). This
should not have any effect but makes manager_startup() more like
manager_reload().
2. Calls manager_recheck_journal(), manager_recheck_dbus(),
manager_enqueue_sync_bus_names() in manager_startup() too. This is a
good idea since during reeexec we pass through manager_startup() and
hence can't assume dbus and journald weren't up yet, hence let's
check if they are ready to be connected to.
3. Include manager_enumerate_perpetual() in manager_reload(), too. This
is not strictly necessary, since these units are included in the
serialization anyway, but it's still a nice thing, in particular as
theoretically the deserialization could fail.

Subject: [PATCH] pam: add a call to pam_namespace
A call to pam_namespace is required so that children of user@.service end up in
a namespace as expected. pam_namespace gets called as part of the stack that
creates a session (login, sshd, gdm, etc.) and those processes end up in a
namespace, but it also needs to be called from our stack which is parallel and
descends from pid1 itself.
The call to pam_namespace is similar to the call to pam_keyinit that was added
in ab79099d1684457d040ee7c28b2012e8c1ea9a4f. The pam stack for user@.service
creates a new session which is disconnected from the parent environment. Both
calls are not suitable for inclusion in the shared part of the stack (e.g.
@system-auth on Fedora/RHEL systems), because for example su/sudo/runuser
should not include them.

Subject: [PATCH] virt: Support detection for ARM64 Hyper-V guests
The detection of Microsoft Hyper-V VMs is done by cpuid currently,
however there is no cpuid on ARM64. And since ARM64 is now a supported
architecture for Microsoft Hyper-V guests[1], then use DMI tables to
detect a Hyper-V guest, which is more generic and works for ARM64.

Subject: [PATCH] coredump: do not allow user to access coredumps with changed
uid/gid/capabilities
When the user starts a program which elevates its permissions via setuid,
setgid, or capabilities set on the file, it may access additional information
which would then be visible in the coredump. We shouldn't make the the coredump
visible to the user in such cases.
Reported-by: Matthias Gerstner <mgerstner@suse.de>
This reads the /proc/<pid>/auxv file and attaches it to the process metadata as
PROC_AUXV. Before the coredump is submitted, it is parsed and if either
at_secure was set (which the kernel will do for processes that are setuid,
setgid, or setcap), or if the effective uid/gid don't match uid/gid, the file
is not made accessible to the user. If we can't access this data, we assume the
file should not be made accessible either. In principle we could also access
the auxv data from a note in the core file, but that is much more complex and
it seems better to use the stand-alone file that is provided by the kernel.
Attaching auxv is both convient for this patch (because this way it's passed
between the stages along with other fields), but I think it makes sense to save
it in general.
We use the information early in the core file to figure out if the program was
32-bit or 64-bit and its endianness. This way we don't need heuristics to guess
whether the format of the auxv structure. This test might reject some cases on
fringe architecutes. But the impact would be limited: we just won't grant the
user permissions to view the coredump file. If people report that we're missing
some cases, we can always enhance this to support more architectures.
I tested auxv parsing on amd64, 32-bit program on amd64, arm64, arm32, and
ppc64el, but not the whole coredump handling.

Subject: [PATCH] systemctl: simplify halt_main()
The code at this point is not able to tell whether it was called as
halt/poweroff/reboot or shutdown with time "now".
The code also takes a shortcut to skip logind if called as root.
That however means asking shutdown for immediate action won't trigger a
wall message.
As per https://github.com/systemd/systemd/issues/8424#issuecomment-374677315
all commands should trigger a wall message.
That simplifies the code as we can try logind first always.
(cherry picked from commit adefc8789b63225662e50ceaa282f9553b5c64eb)
Resolves: #2053273

Subject: [PATCH] systemctl: shutdown don't fallback on auth fail
For shutdowns don't fall back to starting the target directly if talking
to logind failed with auth failure. That would just lead to another
polkit auth attempt.

Currently, the legacy shutdown commands ignore inhibitors and reboot
immediately if run by root. Let's preserve that behavior in RHEL-8 by
default. The new behavior can be turned on by those who want it by
exporting SYSTEMD_NEW_SHUTDOWN=1 .

Subject: [PATCH] pam_systemd: suppress LOG_DEBUG log messages if debugging is
off
In the PAM module we need to suppress LOG_DEBUG messages manually, if
debug logging is not on, as PAM won't do this for us. We did this
correctly for most log messages already, but two were missing. Let's fix
those too.
Fixes: #10822

Subject: [PATCH] journald: add API to move logging from /var to /run again
We now have this nice little Varlink API, let's beef it up a bit.
[dtardon: This diverges from the upstream commit in two ways: One is
that the new action is bound to a signal, as varlink is not available.
The other is that this introduces a new "flag" file
/run/systemd/journal/relinquished, which is essentially the opposite of
/run/systemd/journal/flushed (hence at most one of them may exist at any
time).]

Subject: [PATCH] journalctl: add new --relinquish and --smart-relinquish
options
The latter is identical to the former, but becomes a NOP if
/var/log/journal is on the same mount as /, and thus during shutdown
unmounting /var is not necessary and hence we can keep logging until the
very end.
[dtardon: The only divergence from the upstream commit is the impl. of
relinquish_var().]

Subject: [PATCH] pstore: Tool to archive contents of pstore
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch introduces the systemd pstore service which will archive the
contents of the Linux persistent storage filesystem, pstore, to other storage,
thus preserving the existing information contained in the pstore, and clearing
pstore storage for future error events.
Linux provides a persistent storage file system, pstore[1], that can store
error records when the kernel dies (or reboots or powers-off). These records in
turn can be referenced to debug kernel problems (currently the kernel stuffs
the tail of the dmesg, which also contains a stack backtrace, into pstore).
The pstore file system supports a variety of backends that map onto persistent
storage, such as the ACPI ERST[2, Section 18.5 Error Serialization] and UEFI
variables[3 Appendix N Common Platform Error Record]. The pstore backends
typically offer a relatively small amount of persistent storage, e.g. 64KiB,
which can quickly fill up and thus prevent subsequent kernel crashes from
recording errors. Thus there is a need to monitor and extract the pstore
contents so that future kernel problems can also record information in the
pstore.
The pstore service is independent of the kdump service. In cloud environments
specifically, host and guest filesystems are on remote filesystems (eg. iSCSI
or NFS), thus kdump relies [implicitly and/or explicitly] upon proper operation
of networking software *and* hardware *and* infrastructure. Thus it may not be
possible to capture a kernel coredump to a file since writes over the network
may not be possible.
The pstore backend, on the other hand, is completely local and provides a path
to store error records which will survive a reboot and aid in post-mortem
debugging.
Usage Notes:
This tool moves files from /sys/fs/pstore into /var/lib/systemd/pstore.
To enable kernel recording of error records into pstore, one must either pass
crash_kexec_post_notifiers[4] to the kernel command line or enable via 'echo Y
> /sys/module/kernel/parameters/crash_kexec_post_notifiers'. This option
invokes the recording of errors into pstore *before* an attempt to kexec/kdump
on a kernel crash.
Optionally, to record reboots and shutdowns in the pstore, one can either pass
the printk.always_kmsg_dump[4] to the kernel command line or enable via 'echo Y >
/sys/module/printk/parameters/always_kmsg_dump'. This option enables code on the
shutdown path to record information via pstore.
This pstore service is a oneshot service. When run, the service invokes
systemd-pstore which is a tool that performs the following:
- reads the pstore.conf configuration file
- collects the lists of files in the pstore (eg. /sys/fs/pstore)
- for certain file types (eg. dmesg) a handler is invoked
- for all other files, the file is moved from pstore
- In the case of dmesg handler, final processing occurs as such:
- files processed in reverse lexigraphical order to faciliate
reconstruction of original dmesg
- the filename is examined to determine which dmesg it is a part
- the file is appended to the reconstructed dmesg
For example, the following pstore contents:
root@vm356:~# ls -al /sys/fs/pstore

Configuration file:
The pstore.conf configuration file has four settings, described below.
- Storage : one of "none", "external", or "journal". With "none", this
tool leaves the contents of pstore untouched. With "external", the
contents of the pstore are moved into the /var/lib/systemd/pstore,
as well as logged into the journal. With "journal", the contents of
the pstore are recorded only in the systemd journal. The default is
"external".
- Unlink : is a boolean. When "true", the default, then files in the
pstore are removed once processed. When "false", processing of the
pstore occurs normally, but the pstore files remain.

+ <title>Description</title>
+ <para><filename>systemd-pstore.service</filename> is a system service that archives the
+ contents of the Linux persistent storage filesystem, pstore, to other storage,
+ thus preserving the existing information contained in the pstore, and clearing
+ pstore storage for future error events.</para>
+
+ <para>Linux provides a persistent storage file system, pstore, that can store
+ error records when the kernel dies (or reboots or powers-off). These records in
+ turn can be referenced to debug kernel problems (currently the kernel stuffs
+ the tail of the dmesg, which also contains a stack backtrace, into pstore).</para>
+
+ <para>The pstore file system supports a variety of backends that map onto persistent
+ storage, such as the ACPI ERST and UEFI variables. The pstore backends
+ typically offer a relatively small amount of persistent storage, e.g. 64KiB,
+ which can quickly fill up and thus prevent subsequent kernel crashes from
+ recording errors. Thus there is a need to monitor and extract the pstore
+ contents so that future kernel problems can also record information in the
+ pstore.</para>
+
+ <para>The pstore service is independent of the kdump service. In cloud environments
+ specifically, host and guest filesystems are on remote filesystems (eg. iSCSI
+ or NFS), thus kdump relies [implicitly and/or explicitly] upon proper operation
+ of networking software *and* hardware *and* infrastructure. Thus it may not be
+ possible to capture a kernel coredump to a file since writes over the network
+ may not be possible.</para>
+
+ <para>The pstore backend, on the other hand, is completely local and provides a path
+ to store error records which will survive a reboot and aid in post-mortem
+ debugging.</para>
+
+ <para>The <command>systemd-pstore</command> executable does the actual work. Upon starting,
+ the <filename>pstore.conf</filename> is read to obtain options, then the /sys/fs/pstore
+ directory contents are processed according to the options. Pstore files are written to the
+ journal, and optionally saved into /var/lib/systemd/pstore.</para>
+ </refsect1>
+
+ <refsect1>
+ <title>Configuration</title>
+
+ <para>The behavior of <command>systemd-pstore</command> is configured through the configuration file
+ <filename>/etc/systemd/pstore.conf</filename> and corresponding snippets

Previously, the return value of the last read_full_file() is returned.
This makes the error in read_full_file() is always ignored.

This makes it much easier to debug the program as a normal user, since we
don't need to set up fake input under /sys/fs/pstore/.
Also, let's make the debug output a bit nicer.

Let's use a more standard pattern: allocate memory using greedy_realloc, and
instead of freeing it when we wrote out a chunk, let's just move the cursor
back to the beginning and reuse the memory we allocated previously.
If we fail to allocate the memory for dmesg contents, don't write the dmesg
entry, but let's still process the files to move them out of pstore.

Subject: [PATCH] pstore: fixes for dmesg.txt reconstruction
This patch fixes problems with the re-assembly of the dmesg
from the records stored in pstore.
The current code simply ignores the last 6 characters of the
file name to form a base record id, which then groups any
pstore files with this base id into the reconstructed dmesg.txt.
This approach fails when the following oops generated the
following in pstore:
-rw-------. 1 root root 1808 Oct 27 22:07 dmesg-efi-166692286101001

The above is a interleaved mess of three dmesg dumps.
This patch fixes the above problems, and simplifies the dmesg
reconstruction process. The code now distinguishes between
records on EFI vs ERST, which have differently formatted
record identifiers. Using knowledge of the format of the
record ids allows vastly improved reconstruction process.
With this change in place, the above pstore records now
result in the following:

Furthemore, pstore records on ERST are now able to accurately
identify the change in timestamp sequence in order to start a
new dmesg.txt, as needed.

Subject: [PATCH] units: pull in systemd-pstore.service from sysinit.target
sysinit.target is the target our early boot services are generally
pulled in from, make systemd-pstore.service not an exception of that.
Effectively this doesn't mean much, either way our unit is part of the
initial transaction.

Subject: [PATCH] units: drop dependency on systemd-remount-fs.service from
systemd-pstore.service
This dependency is now generated automatically given we use
StateDirectory=. Moreover the combination of Wants= and After= was too
strong anway, as whether remount-fs is pulled in or not should not be up
to systemd-pstore.service, and in fact is part of the initial
transaction anyway.
[dtardon: This only removes Wants=, not After=, because I haven't
backported the auto-generation code the description talks about. The
code is simple, but it's just an optimisation allowing for slightly
shorter unit files, hence I don't think we really need it.]

Subject: [PATCH] pstore: Run after modules are loaded
The systemd-pstore service takes pstore files on boot and transfers them
to disk. It only does it once on boot and only if it finds any. The typical
location of the pstore on modern systems is the UEFI variable store.
Most distributions ship with CONFIG_EFI_VARS_PSTORE=m. That means, the
UEFI variable store is only available on boot after the respective module
is loaded.
In most situations, the pstore service gets loaded before the UEFI pstore,
so we don't get to transfer logs. Instead, they accumulate, filling up the
pstore over time, potentially breaking the UEFI variable store.
Let's add a service dependency on any kernel module that can provide a
pstore to ensure we only scan for pstate after we can actually see pstate.
I have seen live occurences of systems breaking because we did not erase
the pstates and ran out of UEFI nvram space.
Fixes https://github.com/systemd/systemd/issues/18540

Subject: [PATCH] pstore: do not try to load all known pstore modules
Commit 70e74a5997 ("pstore: Run after modules are loaded") added After=
and Wants= entries for all known kernel modules providing a pstore.
While adding these dependencies on systems where one of the modules is
not present, or not configured, should not have a real affect on the
system, it can produce annoying error messages in the kernel log. E.g.
"mtd device must be supplied (device name is empty)" when the mtdpstore
module is not configured correctly.
Since dependencies cannot be removed with drop-ins, if a distro wants to
remove some of these modules from systemd-pstore.service, they need to
patch units/systemd-pstore.service.in. On the other hand, if they want
to append to the dependencies this can be done by shipping a drop-in.
Since the original intent of the previous commit was to fix [1], which
only requires the efi_pstore module, remove all other kernel module
dependencies from systemd-pstore.service, and let distros ship drop-ins
to add dependencies if needed.

The expect stuff was anything but expected, so let's just backport
the upstream test case and tweak it a bit to account for the missing
parts in our downstream testing infrastructure.

Subject: [PATCH] pager: set $LESSSECURE whenver we invoke a pager
Some extra safety when invoked via "sudo". With this we address a
genuine design flaw of sudo, and we shouldn't need to deal with this.
But it's still a good idea to disable this surface given how exotic it
is.
Prompted by #5666

Subject: [PATCH] test-login: always test sd_pid_get_owner_uid(), modernize
A long time some function only worked when in a session, and the test
didn't execute them when sd_pid_get_session() failed. Let's always call
them to increase coverage.
While at it, let's test for ==0 not >=0 where we don't expect the function
to return anything except 0 or error.

Subject: [PATCH] pager: make pager secure when under euid is changed or
explicitly requested
The variable is renamed to SYSTEMD_PAGERSECURE (because it's not just about
less now), and we automatically enable secure mode in certain cases, but not
otherwise.
This approach is more nuanced, but should provide a better experience for
users:
- Previusly we would set LESSSECURE=1 and trust the pager to make use of
it. But this has an effect only on less. We need to not start pagers which
are insecure when in secure mode. In particular more is like that and is a
very popular pager.
- We don't enable secure mode always, which means that those other pagers can
reasonably used.
- We do the right thing by default, but the user has ultimate control by
setting SYSTEMD_PAGERSECURE.
Fixes #5666.
v2:
- also check $PKEXEC_UID
v3:
- use 'sd_pid_get_owner_uid() != geteuid()' as the condition
(cherry picked from commit 0a42426d797406b4b01a0d9c13bb759c2629d108)
Resolves: #2175624

Subject: [PATCH] test: ignore ENOMEDIUM error from sd_pid_get_cgroup()
Ubuntu builds on the Launchpad infrastructure run inside a chroot that does
not have the sysfs cgroup dirs mounted, so this call will return ENOMEDIUM
from cg_unified_cached() during the build-time testing, for example when
building the package in a Launchpad PPA.

Subject: [PATCH] ci: first part of the source-git automation - commit linter
Add a GitHub Workflow that is triggered on `workflow_run` events.
It uses metadata provided by `redhat-plumbers-in-action/gather-pull-request-metadata`
GitHub Action to get the PR number and the commit metadata.
The commit metadata is then used to check if the commit message contains
all required information (tracker and upstream reference). GitHub Action
responsible for commit verification `redhat-plumbers-in-action/advanced-commit-linter`
is configured via the `advanced-commit-linter.yml` file.

[msekleta: in our version of systemd "const char path*" argument of
path_join() can't be NULL. Here we don't really want any subdirs paths
passed into move_file(), but we can't just pass NULL pointers because
they will be forwarded to path_join(). Hence, let's just pass "/"

Subject: [PATCH] test: Disable LUKS devices from initramfs in QEMU tests
We currently use the host's kernel and initramfs in our QEMU tests.
If the host is running on an encrypted LUKS partition, then the initramfs
will have a crypttab setup looking for the particular root disk it needs to
encrypt before booting into the system.
However, this disk obviously doesn't exist in our QEMU VM, so it turns out
our tests end up waiting for this device to become available, which will
never actually happen, and boot hangs for 90s until that service times out.
[*** ] A start job is running for /dev/disk/by-uuid/01234567-abcd-1234-abcd-0123456789ab (20s / 1min 30s)
In order to prevent this issue, let's pass "rd.luks=0" to disable LUKS in
the initramfs only as part of our default kernel command-line in our QEMU
tests.
This is enough to disable this behavior and prevent the timeout, while at
the same time doesn't conflict with our tests that actually check for LUKS
behavior in the systemd running under test (such as TEST-02-CRYPTSETUP).
Tested: `sudo make -C TEST-02-CRYPTSETUP/ clean setup run`

Subject: [PATCH] sulogin: fix control lost of the current terminal when
default.target is rescue.target
When default.target is rescue.target, exiting from the single-user shell
results in lost of the control of the current terminal. This is because the
operation performed to continue to boot is systemctl default but default.target
is now rescue.target and it is already active. Hence, no new process that
controls the current terminal is created. Users need to make hardware reset to
recover the situation.
This sounds like a bit corner case issue and some might feel configuring
default.target as rescue.target is odd because there are several other ways to
transition to rescue.mode without configuring default.target to rescue.target
such as systemctl rescue or systemd.unit=rescue.target something like
that. However, users unfamiliar with systemd operations tend to come up with
systemctl set-default rescue.target.
To fix this issue, let's transition to default.target only when default.target
is inactive. Otherwise, invoke the single-user shell again to keep control of
the current terminal for users.
This new logic depends on whether D-Bus working well. Exiting without any check
of result of systemctl default could lead to again the control lost of the
current terminal. Hence, add checking results of each D-Bus operations
including systemctl default and invoke the single-user shell if they fail.

Subject: [PATCH] parse-util: in parse_permille() check negative earlier
If 'v' is negative, it's wrong to add the decimal to it, as we'd
actually need to subtract it in this case. But given that we don't want
to allow negative vaues anyway, simply check earlier whether what we
have parsed so far was negative, and react to that before adding the
decimal to it.

Subject: [PATCH] tree-wide: increase granularity of percent specifications all
over the place to permille
We so far had various placed we'd parse percentages with
parse_percent(). Let's make them use parse_permille() instead, which is
downward compatible (as it also parses percent values), and increases
the granularity a bit. Given that on the wire we usually normalize
relative specifications to something like UINT32_MAX anyway changing
from base-100 to base-1000 calculations can be done easily without
breaking compat.
This commit doesn't document this change in the man pages. While
allowing more precise specifcations permille is not as commonly
understood as perent I guess, hence let's keep this out of the docs for
now.

Subject: [PATCH] sd-bus: handle -EINTR return from bus_poll()
In sd_bus_wait(), let's convert EINTR to a return code of 0, thus asking
the caller do loop again and enter sd_bus_process() again (which will
not find any queued events). This way we'll not return an error on
something that isn't really an error. This should typically make sure
things are properly handled by the caller, magically, without eating up
the event entirely, and still giving the caller time to run some code if
they want.
(cherry picked from commit 3022916b4d2483452c3ddbbac9ee7c4372b1cb46)
Resolves: #2172846
