- Think about the types you use. If a value cannot sensibly be
negative, do not use "int", but use "unsigned".
-- Do not use types like "short". They *never* make sense. Use ints,
- longs, long longs, all in unsigned+signed fashion, and the fixed
- size types uint32_t and so on, as well as size_t, but nothing
- else. Do not use kernel types like u32 and so on, leave that to the
- kernel.
+- Use "char" only for actual characters. Use "uint8_t" or "int8_t"
+ when you actually mean a byte-sized signed or unsigned
+ integers. When referring to a generic byte, we generally prefer the
+ unsigned variant "uint8_t". Do not use types based on "short". They
+ *never* make sense. Use ints, longs, long longs, all in
+ unsigned+signed fashion, and the fixed size types
+ uint8_t/uint16_t/uint32_t/uint64_t/int8_t/int16_t/int32_t and so on,
+ as well as size_t, but nothing else. Do not use kernel types like
+ u32 and so on, leave that to the kernel.
- Public API calls (i.e. functions exported by our shared libraries)
must be marked "_public_" and need to be prefixed with "sd_". No
- If you want to concatenate two or more strings, consider using
strjoin() rather than asprintf(), as the latter is a lot
slower. This matters particularly in inner loops.
+
+- Please avoid using global variables as much as you can. And if you
+ do use them make sure they are static at least, instead of
+ exported. Especially in library-like code it is important to avoid
+ global variables. Why are global variables bad? They usually hinder
+ generic reusability of code (since they break in threaded programs,
+ and usually would require locking there), and as the code using them
+ has side-effects make programs intransparent. That said, there are
+ many cases where they explicitly make a lot of sense, and are OK to
+ use. For example, the log level and target in log.c is stored in a
+ global variable, and that's OK and probably expected by most. Also
+ in many cases we cache data in global variables. If you add more
+ caches like this, please be careful however, and think about
+ threading. Only use static variables if you are sure that
+ thread-safety doesn't matter in your case. Alternatively consider
+ using TLS, which is pretty easy to use with gcc's "thread_local"
+ concept. It's also OK to store data that is inherently global in
+ global variables, for example data parsed from command lines, see
+ below.
+
+- If you parse a command line, and want to store the parsed parameters
+ in global variables, please consider prefixing their names with
+ "arg_". We have been following this naming rule in most of our
+ tools, and we should continue to do so, as it makes it easy to
+ identify command line parameter variables, and makes it clear why it
+ is OK that they are global variables.

systemd System and Service Manager
+CHANGES WITH 228:
+
+ * A number of properties previously only settable in unit
+ files are now also available as properties to set when
+ creating transient units programmatically via the bus, as it
+ is exposed with systemd-run's --property=
+ setting. Specifically, these are: SyslogIdentifier=,
+ SyslogLevelPrefix=, TimerSlackNSec=, OOMScoreAdjust=,
+ EnvironmentFile=, ReadWriteDirectories=,
+ ReadOnlyDirectories=, InaccessibleDirectories=,
+ ProtectSystem=, ProtectHome=, RuntimeDirectory=.
+
+ * When creating transient services via the bus API it is now
+ possible to pass in a set of file descriptors to use as
+ STDIN/STDOUT/STDERR for the invoked process.
+
+ * Wherever systemd expects a calendar timestamp specification
+ (like in journalctl's --since= and --until= switches) UTC
+ timestamps are now supported. Timestamps suffixed with "UTC"
+ are now considered to be in Universal Time Coordinated
+ instead of the local timezone. Also, timestamps may now
+ optionally be specified with a sub-second accuracy. Both of
+ these additions also apply to recurring calendar event
+ specification, such as OnCalendar= in timer units.
+
+ * journalctl gained a new "--sync" switch that asks the
+ journal daemon to write all so far unwritten log messages to
+ disk and sync the files, before returning.
+
+ * systemd-tmpfiles learned two new line types "q" and "Q" that
+ operate like "v", but also set up a basic btrfs quota
+ hierarchy when used on a btrfs file system with quota
+ enabled.
+
+ * systemd-detect-virt gained a new --chroot switch to detect
+ whether execution takes place in a chroot() environment.
+
+ * CPUAffinity= now takes CPU index ranges in addition to
+ individual indexes.
+
+ * The various memory-related resource limit settings (such as
+ LimitAS=) now understand the usual K, M, G, ... suffixes to
+ the base of 1024 (IEC). Similar, the time-related resource
+ limit settings understand the usual min, h, day, ...
+ suffixes now.
+
+ * systemd-nspawn gained the new --network-veth-extra= switch
+ to define additional and arbitrarily-named virtual Ethernet
+ links between the host and the container.
+
+ * A new service execution setting PassEnvironment= has been
+ added that allows importing select environment variables
+ from PID1's environment block into the environment block of
+ the service.
+
+ * systemd will now bump the net.unix.max_dgram_qlen to 512 by
+ default now (the kernel default is 16). This is beneficial
+ for avoiding blocking on AF_UNIX/SOCK_DGRAM sockets since it
+ allows substantially larger numbers of queued
+ datagrams. This should increase the capability of systemd to
+ parallelize boot-up, as logging and sd_notify() are unlikely
+ to stall execution anymore. If you need to change the value
+ from the new defaults, use the usual sysctl.d/ snippets.
+
+ * The compression framing format used by the journal or
+ coredump processing has changed to be in line with what the
+ official LZ4 tools generate. LZ4 compression support in
+ systemd was considered unsupported previously, as the format
+ was not compatible with the normal tools. With this release
+ this has changed now, and it is hence safe for downstream
+ distributions to turn it on. While not compressing as well
+ as the XZ,LZ4 is substantially faster, which makes
+ it a good default choice for the compression logic in the
+ journal and in coredump handling.
+
+ * Any reference to /etc/mtab has been dropped from
+ systemd. The file has been obsolete since a while, but
+ systemd refused to work on systems where it was incorrectly
+ set up (it should be a symlink or non-existant). Please make
+ sure to update to util-linux 2.27.1 or newer in conjunction
+ with this systemd release, which also drops any reference to
+ /etc/mtab. If you maintain a distribution make sure that no
+ software you package still references it, as this is a
+ likely source of bugs. There's also a glibc bug pending,
+ asking for removal of any reference to this obsolete file:
+
+ https://sourceware.org/bugzilla/show_bug.cgi?id=19108
+
+ * Support for the ".snapshot" unit type has been removed. This
+ feature turned out to be little useful and little used, and
+ has now been removed from the core and from systemctl.
+
+ * The dependency types RequiresOverridable= and
+ RequisiteOverridable= have been removed from systemd. They
+ have been used only very sparingly to our knowledge and
+ other options that provide a similar effect (such as
+ systemctl --mode=ignore-dependencies) are much more useful
+ and commonly used. Moreover, they were only half-way
+ implemented as the option to control behaviour regarding
+ these dependencies was never added to systemctl. By removing
+ these dependency types the execution engine becomes a bit
+ simpler. Unit files that use these dependencies should be
+ changed to use the non-Overridable dependency types
+ instead. In fact, when parsing unit files with these
+ options, that's what systemd will automatically convert them
+ too, but it will also warn, asking users to fix the unit
+ files accordingly. Removal of these dependency types should
+ only affect a negligible number of unit files in the wild.
+
+ * Behaviour of networkd's IPForward= option changed
+ (again). It will no longer maintain a per-interface setting,
+ but propagate one way from interfaces where this is enabled
+ to the global kernel setting. The global setting will be
+ enabled when requested by a network that is set up, but
+ never be disabled again. This change was made to make sure
+ IPv4 and IPv6 behaviour regarding packet forwarding is
+ similar (as the Linux IPv6 stack does not support
+ per-interface control of this setting) and to minimize
+ surprises.
+
+ * In unit files the behaviour of %u, %U, %h, %s has
+ changed. These specifiers will now unconditionally resolve
+ to the various user database fields of the user that the
+ systemd instance is running as, instead of the user
+ configured in the specific unit via User=. Note that this
+ effectively doesn't change much, as resolving of these
+ specifiers was already turned off in the --system instance
+ of systemd, as we cannot do NSS lookups from PID 1. In the
+ --user instance of systemd these specifiers where correctly
+ resolved, but hardly made any sense, since the user instance
+ lacks privileges to do user switches anyway, and User= is
+ hence useless. Morever, even in the --user instance of
+ systemd behaviour was awkward as it would only take settings
+ from User= assignment placed before the specifier into
+ account. In order to unify and simplify the logic around
+ this the specifiers will now always resolve to the
+ credentials of the user invoking the manager (which in case
+ of PID 1 is the root user).

* wiki: update journal format documentation for lz4 additions
-* When lz4 gets an API for lz4 command output, make use of it to
- compress coredumps in a way compatible with /usr/bin/lz4.
+Janitorial Clean-ups:
+
+* code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
+
+* replace manual readdir() loops with FOREACH_DIRENT or FOREACH_DIRENT_ALL
+
+* Get rid of the last strerror() invocations in favour of %m and strerror_r()
+
+* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
Features:
-* when creating transient services, support passing in a tty fd to use for stdin/stdout
+* PID1: find a way how we can reload unit file configuration for
+ specific units only, without reloading the whole of systemd
+
+* add an explicit parser for LimitNICE= and LimitRTPRIO= that verifies
+ the specified range and generates sane error messages for incorrect
+ specifications. Also, for LimitNICE= maybe introduce a syntax such
+ as "+5" or "-7" in order to make the limits more readable as they
+ are otherwise shifted by 20.
+
+* do something about "/control" subcgroups in the unified cgroup hierarchy
+
+* when we detect that there are waiting jobs but no running jobs, do something
+
+* push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
* add a concept of RemainAfterExit= to scope units
prefixed with /sys generally special.
http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
-* Add PassEnvironment= setting to service units, to import select env vars from PID 1 into the service env block
-
* nspawn: fix logic always print a final newline on output.
https://github.com/systemd/systemd/pull/272#issuecomment-113153176
-* make nspawn's --network-veth switch more powerful:
- http://lists.freedesktop.org/archives/systemd-devel/2015-June/033121.html
-
* man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
-* man: clarify that "machinectl show" shows different information than "machinectl status" (no cgroup tree, no IP addresses, ...)
-
* "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd
* install: include generator dirs in unit file search paths
* .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC
-* create a btrfs qgroup for /var/lib/machines, and add all container
- subvolumes we create to it.
-
* When logging about multiple units (stopping BoundTo units, conflicts, etc.),
log both units as UNIT=, so that journalctl -u triggers on both.
* networkd/udev: implement SR_IOV configuration in .link files:
http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
-* When RLIMIT_NPROC is set from a unit file it currently always is set
- for root, not for the user set in User=, which makes it
- useless. After fixing this, set RLIMIT_NPROC for
- systemd-journal-xyz, and all other of our services that run under
- their own user ids, and use User= (but only in a world where userns
- is ubiquitous since otherwise we cannot invoke those daemons on the
- host AND in a container anymore). Also, if LimitNPROC= is used
- without User= we should warn and refuse operation.

* logind: maybe allow configuration of the StopTimeout for session scopes
* Find a solution for SMACK capabilities stuff:
http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
-* port libmount hookup to use API's own inotify interface, as soon as that is table in libmount
-
* "systemctl preset-all" should probably order the unit files it
operates on lexicographically before starting to work, in order to
ensure deterministic behaviour if two unit files conflict (like DMs
* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
-* code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead
-
* introduce systemd-timesync-wait.service or so to sync on an NTP fix?
* systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle
* maybe do not install getty@tty1.service symlink in /etc but in /usr?
-* fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
- https://bugzilla.redhat.com/show_bug.cgi?id=812826
-
* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
- add API to close/reopen/get fd for journal client fd in libsystemd-journal.
- fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
- declare the local journal protocol stable in the wiki interface chart
- - journal: reuse XZ context
- sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
- journald: when dropping msgs due to ratelimit make sure to write
"dropped %u messages" not only when we are about to print the next
- document systemd-journal-flush.service properly
- documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
- man: document the very specific env the shutdown drop-in tools live in
- - man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
- man: add more examples to man pages
- man: maybe sort directives in man pages, and take sections from --help and apply them to man too
- add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
- systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
- systemctl: "Journal has been rotated since unit was started." message is misleading
- - support "systemctl stop foobar@.service" to stop all units matching a certain template
- - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
- better error message if you run systemctl without systemd running
- systemctl status output should should include list of triggering units and their status
o DST changes
- Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
- calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
- - when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
- Modulate timer frequency based on battery state
* add libsystemd-password or so to query passwords during boot using the password agent logic
* introduce Type=pid-file
-* change Requires=basic.target to RequisiteOverride=basic.target
-
* when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
* ExecOnFailure=/usr/bin/foo
* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
-* default unix qlen is too small (10). bump sysctl? add sockopt?
-
* save coredump in Windows/Mozilla minidump format
* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
- add Scope= parsing option for [Network]
- properly handle routerless dhcp leases
- add more attribute support for SIT tunnel
- - work with non-ethernet devices
+ - work with non-Ethernet devices
- add support for more bond options
* networkd-wait-online:
* drop accountsservice's StandardOutput=syslog and Type=dbus fields
-* dbus upstream still refers to dbus.target and should not
-
* dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
-* add "# export SYSTEMD_PAGER=" to bash login
-
* /usr/bin/service should actually show the new command line
* fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=
* use secure_getenv() instead of getenv() where appropriate
* link up selected blog stories from man pages and unit files Documentation= fields

-
- <para>Snapshot units are not configured via unit configuration
- files. Nonetheless they are named similar to filenames. A unit
- whose name ends in <literal>.snapshot</literal> refers to a
- dynamic snapshot of the systemd runtime state.</para>
-
- <para>Snapshots are not configured on disk but created dynamically
- via <command>systemctl snapshot</command> (see
- <citerefentry><refentrytitle>systemctl</refentrytitle><manvolnum>1</manvolnum></citerefentry>
- for details) or an equivalent command. When created, they will
- automatically get dependencies on the currently activated units.
- They act as saved runtime state of the systemd manager. Later on,
- the user may choose to return to the saved state via
- <command>systemctl isolate</command>. They are useful to roll back
- to a defined state after temporarily starting/stopping services or
- similar.</para>

+ <listitem><para>Similar to <varname>q</varname>. However,
+ instead of copying the higher-level quota group assignments
+ from the parent as-is, the lowest quota group of the parent
+ subvolume is determined that is not the leaf quota
+ group. Then, an "intermediary" quota group is inserted that
+ is one level below this level, and shares the same ID part
+ as the specified subvolume. If no higher-level quota group
+ exists for the parent subvolume, a new quota group at level
+ 255 sharing the same ID as the specified subvolume is
+ inserted instead. This new intermediary quota group is then
+ assigned to the parent subvolume's higher-level quota
+ groups, and the specified subvolume's leaf quota group is
+ assigned to it.</para>
+
+ <para>Effectively, this has a similar effect as
+ <varname>q</varname>, however introduces a new higher-level
+ quota group for the specified subvolume that may be used to
+ enforce limits and accounting to the specified subvolume and
+ children subvolume created within it. Thus, by creating
+ subvolumes only via <varname>q</varname> and
+ <varname>Q</varname>, a concept of "subtree quotas" is
+ implemented. Each subvolume for which <varname>Q</varname>
+ is set will get a "subtree" quota group created, and all
+ child subvolumes created within it will be assigned to
+ it. Each subvolume for which <varname>q</varname> is set
+ will not get such a "subtree" quota group, but it is ensured
+ that they are added to the same "subtree" quota group as their
+ immediate parents.</para>
+
+ <para>It is recommended to use
+ <varname>Q</varname> for subvolumes that typically contain
+ further subvolumes, and where it is desirable to have
+ accounting and quota limits on all child subvolumes
+ together. Examples for <varname>Q</varname> are typically
+ <filename>/home</filename> or
+ <filename>/var/lib/machines</filename>. In contrast,
+ <varname>q</varname> should be used for subvolumes that
+ either usually do not include further subvolumes or where no
+ accounting and quota limits are needed that apply to all
+ child subvolumes together. Examples for <varname>q</varname>
+ are typically <filename>/var</filename> or
+ <filename>/var/tmp</filename>. As with <varname>Q</varname>,
+ <varname>q</varname> has no effect on the quota group
