In libudev (which es much older code than the rest of systemd), we
propagate errors in functions not returning an int, via (positive) errno
(i.e. libc-style), and as negative Exyz values in those returning an int
(much preferred, i.e. Linux kernel style). Let's fix up a few place,
where this was incorrectly done, or not done at all.
Fixes: #6613
in other way we will get a warning message:
../src/core/kmod-setup.c:83:13: warning: ‘has_virtio_rng’ defined but
not used [-Wunused-function]
static bool has_virtio_rng(void) {
^~~~~~~~~~~~~~
If dbus is already down during shutdown, we can't propagate the cgroup
release message anymore, but that's expected and nothing to warn about.
Hence let's downgrade the message from LOG_WARN to LOG_DEBUG.
Fixes: #6777
glibc appears to propagate different errors in different ways, let's fix
this up, so that our own code doesn't get confused by this.
See #6752 + #6737 for details.
Fixes: #6755
Trying to connect otherwise is pointless, because if socket isn't around
we won't connect. However, when dbus.socket is present we attempt to
connect. That attempt can't succeed because we are then supposed
to activate dbus.service as a response to connection from
us. This results in deadlock.
Fixes#6303
'journalctl --vacuum-*' does not suppress output message with --quiet.
Let journal_directory_vacuum honors --quiet to fix the problem.

They’re counterparts to the existing set-log-level and set-log-target
verbs, simply printing the current value to stdout. This makes it
slightly easier to temporarily change the log level and/or target and
then restore the old value(s).
Parse DNS IPv6 addresses and DNS server lifetime from .network files
so that they can be included in Router Advertisement RDNSS options.
RDNSS address and lifetime information is added to the
[IPv6PrefixDelegation] section according to the following syntax:
DNS=2001:db8::a:b 2001:db8::c:d
DNSLifetimeSec=1042
to initialize Network variables when Anonymize is true.
* do not send hostname
* client identifier set to MAC
* do not send vendor class identifier
* do not send other PRL options
Newer kernels will emit uevents with "bind" and "unbind" actions. These
uevents will be issued when driver is bound to or unbound from a device.
"Bind" events are helpful when device requires a firmware to operate
properly, and driver is unable to create a child device before firmware
is properly loaded.
For some reason systemd validates actions and drops the ones it does not
know, instead of passing them on through as old udev did, so we need to
explicitly teach it about them.
If a path passes though an autofs filesystem, then accessing
the path might trigger and automount. As systemd-tmpfiles is run before
the network is up, and as automounts are often used for networked
filesystems, this can cause a deadlock.
So chase_symlinks is enhance to accept a new flag which tells it
to check for autofs, and return -EREMOTE if autofs is found.
tmpfiles is changed to check just before acting on a path so that it
can avoid autofs even if a symlink was created earlier by tmpfiles
that would send this path through an autofs.
This fixes a deadlock that happens when /home is listed in /etc/fstab as
x-systemd.automount for an NFS directory.
If a unit file contains multiple CapabilityBoundingSet= or
AmbientCapabilities= lines, e.g.,
===
CapabilityBoundingSet=CAP_A CAP_B
CapabilityBoundingSet=~CAP_B CAP_C
===
before this commit, it results all capabilities except CAP_C are set to
CapabilityBoundingSet=, as each lines are always merged by OR.
This commit makes lines prefixed with ~ are merged by AND. So, for the
above example only CAP_A is set.
This makes easier to drop capabilities with drop-in config files.
systemctl would try to load the properties of the unit, which is impossible
for template names, and the whole operation would fail. It seems that this
regression was introduced in 00c83b4300.
Export the part of unit_find_paths() responsible for locating instance unit
fragments and reuse it from unit_exists() to fix the handling of template
units.
Fixes#6412.
