systemd System and Service Manager

CHANGES WITH 236:

* The modprobe.d/ drop-in for the bonding.ko kernel module introduced
in v235 has been extended to also set the dummy.ko module option
numdummies=0, preventing the kernel from automatically creating
dummy0. All dummy interfaces must now be explicitly created.

* Unknown '%' specifiers in configuration files are now rejected. This
applies to units and tmpfiles.d configuration. Any percent characters
that are followed by a letter or digit that are not supposed to be
interpreted as the beginning of a specifier should be escaped by
doubling ("%%"). (So "size=5%" is still accepted, as well as
"size=5%,foo=bar", but not "LABEL=x%y%z" since %y and %z are not
valid specifiers today.)

* systemd-resolved now maintains a new dynamic
/run/systemd/resolve/stub-resolv.conf compatibility file. It is
recommended to make /etc/resolv.conf a symlink to it. This file
points at the systemd-resolved stub DNS 127.0.0.53 resolver and
includes dynamically acquired search domains, achieving more correct
DNS resolution by software that bypasses local DNS APIs such as NSS.

* The "uaccess" udev tag has been dropped from /dev/kvm and
/dev/dri/renderD*. These devices now have the 0666 permissions by
default (but this may be changed at build-time). /dev/dri/renderD*
will now be owned by the "render" group along with /dev/kfd.

* "DynamicUser=yes" has been enabled for systemd-timesyncd.service,
systemd-journal-gatewayd.service and
systemd-journal-upload.service. This means "nss-systemd" must be
enabled in /etc/nsswitch.conf to ensure the UIDs assigned to these
services are resolved properly.

* In /etc/fstab two new mount options are now understood:
x-systemd.makefs and x-systemd.growfs. The former has the effect that
the configured file system is formatted before it is mounted, the
latter that the file system is resized to the full block device size
after it is mounted (i.e. if the file system is smaller than the
partition it resides on, it's grown). This is similar to the fsck
logic in /etc/fstab, and pulls in systemd-makefs@.service and
systemd-growfs@.service as necessary, similar to
systemd-fsck@.service. Resizing is currently only supported on ext4
and btrfs.

* In systemd-networkd, the IPv6 RA logic now optionally may announce
DNS server and domain information.

* Support for the LUKS2 on-disk format for encrypted partitions has
been added. This requires libcryptsetup2 during compilation and
runtime.

* The systemd --user instance will now signal "readiness" when its
basic.target unit has been reached, instead of when the run queue ran
empty for the first time.

* Tmpfiles.d with user configuration are now also supported.
systemd-tmpfiles gained a new --user switch, and snippets placed in
~/.config/user-tmpfiles.d/ and corresponding directories will be
executed by systemd-tmpfiles --user running in the new
systemd-tmpfiles-setup.service and systemd-tmpfiles-clean.service
running in the user session.

* Unit files and tmpfiles.d snippets learnt three new % specifiers:
%S resolves to the top-level state directory (/var/lib for the system
instance, $XDG_CONFIG_HOME for the user instance), %C resolves to the
top-level cache directory (/var/cache for the system instance,
$XDG_CACHE_HOME for the user instance), %L resolves to the top-level
logs directory (/var/log for the system instance,
$XDG_CONFIG_HOME/log/ for the user instance). This matches the
existing %t specifier, that resolves to the top-level runtime
directory (/run for the system instance, and $XDG_RUNTIME_DIR for the
user instance).

* journalctl learnt a new parameter --output-fields= for limiting the
set of journal fields to output in verbose and JSON output modes.

* systemd-timesyncd's configuration file gained a new option
RootDistanceMaxSec= for setting the maximum root distance of servers
it'll use, as well as the new options PollIntervalMinSec= and
PollIntervalMaxSec= to tweak the minimum and maximum poll interval.

* bootctl gained a new command "list" for listing all available boot
menu items on systems that follow the boot loader specification.

* systemctl gained a new --dry-run switch that shows what would be done
instead of doing it, and is currently supported by the shutdown and
sleep verbs.

* ConditionSecurity= can now detect the TOMOYO security module.

* Unit file [Install] sections are now also respected in unit drop-in
files. This is intended to be used by drop-ins under /usr/lib/.

* systemd-firstboot may now also set the initial keyboard mapping.

* Udev "changed" events for devices which are exposed as systemd
.device units are now propagated to units specified in
ReloadPropagatedFrom= as reload requests.

* If a udev device has a SYSTEMD_WANTS= property containing a systemd
unit template name (i.e. a name in the form of 'foobar@.service',
without the instance component between the '@' and - the '.'), then
the escaped sysfs path of the device is automatically used as the
instance.

* SystemCallFilter= in unit files has been extended so that an "errno"
can be specified individually for each system call. Example:
SystemCallFilter=~uname:EILSEQ.

* The cgroup delegation logic has been substantially updated. Delegate=
now optionally takes a list of controllers (instead of a boolean, as
before), which lists the controllers to delegate at least.

* The networkd DHCPv6 client now implements the FQDN option (RFC 4704).

* A new LogLevelMax= setting configures the maximum log level any
process of the service may log at (i.e. anything with a lesser
priority than what is specified is automatically dropped). A new
LogExtraFields= setting allows configuration of additional journal
fields to attach to all log records generated by any of the unit's
processes.

* New StandardInputData= and StandardInputText= settings along with the
new option StandardInput=data may be used to configure textual or
binary data that shall be passed to the executed service process via
standard input, encoded in-line in the unit file.

* StandardInput=, StandardOutput= and StandardError= may now be used to
connect stdin/stdout/stderr of executed processes directly with a
file or AF_UNIX socket in the file system, using the new "file:" option.

* A new unit file option CollectMode= has been added, that allows
tweaking the garbage collection logic for units. It may be used to
tell systemd to garbage collect units that have failed automatically
(normally it only GCs units that exited successfully). systemd-run
and systemd-mount expose this new functionality with a new -G option.

* "machinectl bind" may now be used to bind mount non-directories
(i.e. regularfiles, devices, fifos, sockets).

* systemd-analyze gained a new verb "calendar" for validating and
testing calendar time specifications to use for OnCalendar= in timer
units. Besides validating the expression it will calculate the next
time the specified expression would elapse.

* In addition to the pre-existing FailureAction= unit file setting
there's now SuccessAction=, for configuring a shutdown action to
execute when a unit completes successfully. This is useful in
particular inside containers that shall terminate after some workload
has been completed. Also, both options are now supported for all unit
types, not just services.

* networkds's IP rule support gained two new options
IncomingInterface= and OutgoingInterface= for configuring the incoming
and outgoing interfaces of configured rules. systemd-networkd also
gained support for "vxcan" network devices.

* networkd gained a new setting RequiredForOnline=, taking a
boolean. If set, systemd-wait-online will take it into consideration
when determining that the system is up, otherwise it will ignore the
interface for this purpose.

* The sd_notify() protocol gained support for a new operation: with
FDSTOREREMOVE=1 file descriptors may be removed from the per-service
store again, ahead of POLLHUP or POLLERR when they are removed
anyway.

* A new document UIDS-GIDS.md has been added to the source tree, that
documents the UID/GID range and assignment assumptions and
requirements of systemd.

* The watchdog device PID 1 will ping may now be configured through the
WatchdogDevice= configuration file setting, or by setting the
systemd.watchdog_service= kernel commandline option.

* systemd-resolved's gained support for registering DNS-SD services on
the local network using MulticastDNS. Services may either be
registered by dropping in a .dnssd file in /etc/systemd/dnssd/ (or
the same dir below /run, /usr/lib), or through its D-Bus API.

* The sd_notify() protocol can now with EXTEND_TIMEOUT_USEC=microsecond
extend the effective start, runtime, and stop time. The service must
continue to send EXTEND_TIMEOUT_USEC within the period specified to
prevent the service manager from making the service as timedout.

* systemd-resolved's DNSSEC support gained support for RFC 8080
(Ed25519 keys and signatures).

* The systemd-resolve command line tool gained a new set of options
--set-dns=, --set-domain=, --set-llmnr=, --set-mdns=, --set-dnssec=,
--set-nta= and --revert to configure per-interface DNS configuration
dynamically during runtime. It's useful for pushing DNS information
into systemd-resolved from DNS hook scripts that various interface
managing software supports (such as pppd).

* systemd-nspawn gained a new --network-namespace-path= command line
option, which may be used to make a container join an existing
network namespace, by specifying a path to a "netns" file.

CHANGES WITH 235:

* INCOMPATIBILITY: systemd-logind.service and other long-running
services now run inside an IPv4/IPv6 sandbox, prohibiting them any IP
communication with the outside. This generally improves security of
the system, and is in almost all cases a safe and good choice, as
these services do not and should not provide any network-facing
functionality. However, systemd-logind uses the glibc NSS API to
query the user database. This creates problems on systems where NSS
is set up to directly consult network services for user database
lookups. In particular, this creates incompatibilities with the
"nss-nis" module, which attempts to directly contact the NIS/YP
network servers it is configured for, and will now consistently
fail. In such cases, it is possible to turn off IP sandboxing for
systemd-logind.service (set IPAddressDeny= in its [Service] section
to the empty string, via a .d/ unit file drop-in). Downstream
distributions might want to update their nss-nis packaging to include
such a drop-in snippet, accordingly, to hide this incompatibility
from the user. Another option is to make use of glibc's nscd service
to proxy such network requests through a privilege-separated, minimal
local caching daemon, or to switch to more modern technologies such
sssd, whose NSS hook-ups generally do not involve direct network
access. In general, we think it's definitely time to question the
implementation choices of nss-nis, i.e. whether it's a good idea
today to embed a network-facing loadable module into all local
processes that need to query the user database, including the most
trivial and benign ones, such as "ls". For more details about
IPAddressDeny= see below.

* A new modprobe.d drop-in is now shipped by default that sets the
bonding module option max_bonds=0. This overrides the kernel default,
to avoid conflicts and ambiguity as to whether or not bond0 should be

* add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for

* document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document

* rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
magic meaning and is no longer upgraded to something else if set explicitly.

* in the long run: permit a system with /etc/machine-id linked to /dev/null, to
make it lose its identity, i.e. be anonymous. For this we'd have to patch
through the whole tree to make all code deal with the case where no machine
ID is available.

* optionally, collect cgroup resource data, and store it in per-unit RRD files,
suitable for processing with rrdtool. Add bus API to access this data, and
possibly implement a CPULoad property based on it.

running as root. Quota should probably cover all the special dirs such as
StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
is set, plus the whole disk space any image configured with RootImage=.

* Introduce "exit" as an EmergencyAction value, and allow to configure a
per-unit success/failure exit code to configure. This would be useful for
running commands inside of services inside of containers, which could then
propagate their failure state all the way up.

* In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
disks to see if the UID is already in use.

* add dissect_image_warn() as a wrapper around dissect_image() that prints
friendly log messages for the returned errors, so that we don't have to
duplicate that in nspawn, systemd-dissect and PID 1.

so that we do not keep /var busy. This needs to happen synchronously,
@@ -626,19 +652,21 @@ Features:
- add journalctl -H that talks via ssh to a remote peer and passes through
binary logs data
- add a version of --merge which also merges /var/log/journal/remote
- log accumulated resource usage after each service invocation
- journalctl: -m should access container journals directly by enumerating
them via machined, and also watch containers coming and going.
Benefit: nspawn --ephemeral would start working nicely with the journal.
- assign MESSAGE_ID to log messages about failed services

* add a test if all entries in the catalog are properly formatted.
(Adding dashes in a catalog entry currently results in the catalog entry
being silently skipped. journalctl --update-catalog must warn about this,
and we should also have a unit test to check that all our message are OK.)

* document:
- document that deps in [Unit] sections ignore Alias= fields in
[Install] units of other units, unless those units are disabled
- man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
- document the exit codes when services fail before they are exec()ed
- document that service reload may be implemented as service reexec
- document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
- add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
- document systemd-journal-flush.service properly
- documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
