3 * Many manager configuration settings that are only applicable to user
4 manager or system manager can be always set. It would be better to reject
5 them when parsing config.
9 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
11 * wiki: update journal format documentation for lz4 additions
15 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
17 * rework mount.c and swap.c to follow proper state enumeration/deserialization
18 semantics, like we do for device.c now
22 * We should probably replace /var/log/README, /etc/rc.d/README with symlinks
23 that are linked to these places instead of copied. After all they are
26 * seed: check if first-boot and then don't do anything
28 * logind: rework pam_logind to also do a bus call in case of invocation from
29 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
30 behaviour selectable via pam module option.
32 * introduce a new per-process uuid, similar to the boot id, the machine id, the
33 invocation id, that is derived from process creds, specifically a hashed
34 combination of AT_RANDOM + getpid() + the starttime from
35 /proc/self/status. Then add these ids implicitly when logging. Deriving this
36 uuid from these three things has the benefit that it can be derived easily
37 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
40 * let's not GC a unit while its ratelimits are still pending
42 * when killing due to service watchdog timeout maybe detect whether target
43 process is under ptracing and then log loudly and continue instead.
45 * introduce a new group to own TPM devices
47 * make rfkill uaccess controllable by default, i.e. steal rule from
48 gnome-bluetooth and friends
50 * warn if udev rules files are marked executable (docker?)
52 * tweak journald context caching. In addition to caching per-process attributes
53 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
54 keyed by cgroup path, and guarded by ctime changes. This should provide us
55 with a nice speed-up on services that have many processes running in the same
58 * make MAINPID= message reception checks even stricter: if service uses User=,
59 then check sending UID and ignore message if it doesn't match the user or
62 * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
65 * when importing an fs tree with machined, optionally apply userns-rec-chown
67 * when importing an fs tree with machined, complain if image is not an OS
69 * Maybe introduce a helper safe_exec() or so, which is to execve() which
70 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
71 to 1K implicitly, unless explicitly opted-out.
73 * rework seccomp/nnp logic that even if User= is used in combination with
74 a seccomp option we don't have to set NNP. For that, change uid first whil
75 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
77 * add a concept for automatically loading per-unit secrets off disk and
78 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
79 ConfigurationDirectory=.
81 * when no locale is configured, default to UEFI's PlatformLang variable
83 * When logind.conf contains HandleLidSwitch=suspend-then-hibernate and we can't
84 hibernate because the swap partition isn't large enough, still suspend
86 * bootctl,sd-boot: actually honour the "architecture" key
88 * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
89 usefaultd() and make systemd-analyze check for it.
91 * paranoia: whenever we process passwords, call mlock() on the memory
92 first. i.e. look for all places we use free_and_erasep() and
93 augment them with mlock(). Also use MADV_DONTDUMP.
95 * Move RestrictAddressFamily= to the new cgroup create socket
97 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
100 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
101 log.c and sd-journal-send
103 * optionally: turn on cgroup delegation for per-session scope units
105 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
107 * optionally, if a per-partition GPT flag is set for the root/home/… partitions
108 format the partition on next boot and unset the flag, in order to implement
109 factory reset. also, add a second flag that simply indicates whether such a
110 scheme is supported. then, add a tool (or maybe beef up systemd-dissect) to
111 show state of these flags, and optionally trigger such a factory reset on
112 next boot by setting the flag.
114 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
115 can add in file system drivers and such
117 * sd-boot: optionally, show boot menu when previous default boot item has
118 non-zero "tries done" count
120 * maybe set a special xattr on cgroups that have delegate=yes set, to make it
121 easy to mark cut points
123 * introduce an option (or replacement) for "systemctl show" that outputs all
124 properties as JSON, similar to busctl's new JSON output. In contrast to that
125 it should skip the variant type string though.
127 * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
128 contains some identifier for the project, which allows us to include
129 clickable links to source files generating these log messages. The identifier
130 could be some abberviated URL prefix or so (taking inspiration from Go
131 imports). For example, for systemd we could use
132 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
133 sufficient to build a link by prefixing "http://" and suffixing the
136 * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
137 make clickable links from log messages carrying a MESSAGE_ID, that lead to
138 some explanatory text online.
140 * maybe extend .path units to expose fanotify() per-mount change events
142 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
143 output of "systemctl list-units" slightly by showing the tree structure of
144 the slices, and the units attached to them.
146 * the a-posteriori stopping of units bound to units that disappeared logic
147 should be reworked: there should be a queue of units, and we should only
148 enqeue stop jobs from a defer event that processes queue instead of
149 right-away when we find a unit that is bound to one that doesn't exist
150 anymore. (similar to how the stop-unneeded queue has been reworked the same
153 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
154 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
155 for hangup or ^D before passing on the EOF.
157 * When reloading configuration PID 1 should reset all its properties to the
158 original defaults before calling parse_config()
160 * nspawn: greater control over selinux label?
162 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
165 1. add resume_offset support to the resume code (i.e. support swap files
167 2. check if swap is on weird storage and refuse if so
168 3. add autodetection of hibernation images
170 * cgroups: use inotify to get notified when somebody else modifies cgroups
171 owned by us, then log a friendly warning.
173 * beef up log.c with support for stripping ANSI sequences from strings, so that
174 it is OK to include them in log strings. This would be particularly useful so
175 that our log messages could contain clickable links for example for unit
176 files and suchlike we operate on.
178 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
180 * add attach --enable and attach --now (for attach+enable+start)
182 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
183 selected user is resolvable in the service even if it ships its own /etc/passwd)
185 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
186 other doesn't. What a disaster. Probably to exclude it. Also
187 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
190 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
191 usually IN_ATTRIB is the right way to watch deleted files, as the former only
192 fires when a file is actually removed from disk, i.e. the link count drops to
193 zero and is not open anymore, while the latter happens when a file is
194 unlinked from any dir.
196 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
198 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
200 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
202 * SuccessExitStatus= and friends should probably also accept symbolic exit
203 codes names, i.e. error codes from the list maintained in exit-codes.[ch]
205 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
206 files and directories that are left writable for a unit, and which are
207 removed after the unit goes down again. A bit like --ephemeral for
208 systemd-nspawn but for system services. If used together with RootImage= this
209 should reflink the image file itself.
211 Related: add Ephemeral=<path1> <path2> … which would allow marking
212 specific paths only like this.
214 * add CopyFile= or so as unit file setting that may be used to copy files or
215 directory trees from the host to the services RootImage= and RootDirectory=
216 environment. Which we can use for /etc/machine-id and in particular
217 /etc/resolv.conf. Should be smart and do something useful on read-only
218 images, for example fallback to read-only bind mounting the file instead.
220 * show invocation ID in systemd-run output
222 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
224 * tree-wide: ensure we always block the signals we hook into with
225 sd_event_add_signal() first
227 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
228 and so on, which would mean we could report errors and such.
230 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
233 * introduce DefaultSlice= or so in system.conf that allows changing where we
234 place our units by default, i.e. change system.slice to something
235 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
236 be moved somewhere else too. Finally machined and logind should get similar
237 options so that it is possible to move user session scopes and machines to a
238 different slice too by default. Usecase: people who want to put resources on
239 the entire system, with the exception of one specific service. See:
240 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
242 * maybe rework get_user_creds() to query the user database if $SHELL is used
243 for root, but only then.
245 * be stricter with fds we receive for the fdstore: close them asynchronously
247 * calenderspec: add support for week numbers and day numbers within a
248 year. This would allow us to define "bi-weekly" triggers safely.
250 * sd-bus: add vtable flag, that may be used to request client creds implicitly
251 and asynchronously before dispatching the operation
253 * make use of ethtool veth peer info in machined, for automatically finding out
254 host-side interface pointing to the container.
256 * add some special mode to LogsDirectory=/StateDirectory=… that allows
257 declaring these directories without necessarily pulling in deps for them, or
258 creating them when starting up. That way, we could declare that
259 systemd-journald writes to /var/log/journal, which could be useful when we
260 doing disk usage calculations and so on.
262 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
264 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
266 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
267 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
268 as the unit is running or has a job queued.
270 * support projid-based quota in machinectl for containers
272 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
273 introduced) as the RTC epoch, instead of the mtime of NEWS.
275 * add a way to lock down cgroup migration: a boolean, which when set for a unit
276 makes sure the processes in it can never migrate out of it
278 * blog about fd store and restartable services
280 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
282 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
283 magic meaning and is no longer upgraded to something else if set explicitly.
285 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
286 make it lose its identity, i.e. be anonymous. For this we'd have to patch
287 through the whole tree to make all code deal with the case where no machine
290 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
291 suitable for processing with rrdtool. Add bus API to access this data, and
292 possibly implement a CPULoad property based on it.
294 * beef up pam_systemd to take unit file settings such as cgroups properties as
297 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
298 the quota of a the user indicated in User= via unit file settings, like the
299 other resource management concepts. Would mix nicely with DynamicUser=1. Or
300 alternatively, do this with projids, so that we can also cover services
301 running as root. Quota should probably cover all the special dirs such as
302 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
303 is set, plus the whole disk space any image configured with RootImage=.
305 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
306 disks to see if the UID is already in use.
308 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
309 for all units. It should be both a way to pin units into memory as well as a
310 wait to retrieve their exit data.
312 * expose IO accounting data on the bus, show it in systemd-run --wait and log
313 about it in the resource log message
315 * show whether a service has out-of-date configuration in "systemctl status" by
316 using mtime data of ConfigurationDirectory=.
318 * replace all remaining uses of fgets() + LINE_MAX by read_line()
320 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
321 creates a static, persistent user rather than a dynamic, transient user. We
322 can leverage code from sysusers.d for this.
324 * add some optional flag to ReadWritePaths= and friends, that has the effect
325 that we create the dir in question when the service is started. Example:
327 ReadWritePaths=:/var/lib/foobar
329 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
330 the sd-journal logging socket, and, if the timeout is set to 0, sets
331 O_NONBLOCK on it. That way people can control if and when to block for
334 * hostnamed: populate form factor data from a new hwdb database, so that old
335 yogas can be recognized as "convertible" too, even if they predate the DMI
336 "convertible" form factor
338 * Maybe add a small tool invoked early at boot, that adds in or resizes
339 partitions automatically, to be used when the media used is actually larger
340 than the image written onto it is.
342 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
343 after all. Be strict however, only support the equivalent of nspawn's
344 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
347 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
348 the service cgroup, which is supposed to monitor the service, and when it
349 exits the service is considered failed by its monitor.
351 * track the per-service PAM process properly (i.e. as an additional control
352 process), so that it may be queried on the bus and everything.
354 * add a new "debug" job mode, that is propagated to unit_start() and for
355 services results in two things: we raise SIGSTOP right before invoking
356 execve() and turn off watchdog support. Then, use that to implement
357 "systemd-gdb" for attaching to the start-up of any system service in its
360 * maybe introduce gpt auto discovery for /var/tmp?
362 * maybe add gpt-partition-based user management: each user gets his own
363 LUKS-encrypted GPT partition with a new GPT type. A small nss module
364 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
365 way: the partition index is added as offset to some fixed base uid. User name
366 is stored in GPT partition name. A PAM module authenticates the user via the
367 LUKS partition password. Benefits: strong per-user security, compatibility
368 with stateless/read-only/verity-enabled root. (other idea: do this based on
369 loopback files in /home, without GPT involvement)
371 * gpt-auto logic: introduce support for discovering /var matching an image. For
372 that, use a partition type UUID that is hashed from the OS name (as encoded
373 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
374 field of the root partition. This way can easily support multiple OS
375 installations on the same GPT partition table, without problems with
376 unmatched /var partitions.
378 * gpt-auto logic: related to the above, maybe support a "secondary" root
379 partition, that is mounted to / and is writable, and where the actual root's
380 /usr is mounted into.
382 * gpt-auto logic: support encrypted swap, add kernel cmdline option to force it, and honour a gpt bit about it, plus maybe a configuration file
384 * drop nss-myhostname in favour of nss-resolve?
386 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
387 then use that for the setting used in user@.service. It should be understood
388 relative to the configured default value.
390 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
392 * enable LockMLOCK to take a percentage value relative to physical memory
394 * Permit masking specific netlink APIs with RestrictAddressFamily=
396 * nspawn: support that /proc, /sys/, /dev are pre-mounted
398 * define gpt header bits to select volatility mode
400 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
402 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
404 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
406 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
408 * ProtectKeyRing= to take keyring calls away
410 * RemoveKeyRing= to remove all keyring entries of the specified user
412 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
413 on PID 1 with the relevant signals, and makes relevant files in /sys and
414 /proc (such as the sysrq stuff) unavailable
416 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
418 * journalctl: make sure -f ends when the container indicated by -M terminates
420 * mount: automatically search for "main" partition of an image has multiple
423 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
426 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
427 find a way to map the User=/Group= of the service to the right name. This way
428 a user/group for a service only has to exist on the host for the right
431 * add bus API for creating unit files in /etc, reusing the code for transient units
433 * add bus API to remove unit files from /etc
435 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
437 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
438 kernel doesn't support linkat() that replaces existing files, currently)
440 * transient units: don't bother with actually setting unit properties, we
441 reload the unit file anyway
443 * journald: sigbus API via a signal-handler safe function that people may call
444 from the SIGBUS handler
446 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
448 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
449 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
451 * cache sd_event_now() result from before the first iteration...
453 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
455 * PID1: find a way how we can reload unit file configuration for
456 specific units only, without reloading the whole of systemd
458 * add an explicit parser for LimitRTPRIO= that verifies
459 the specified range and generates sane error messages for incorrect
462 * when we detect that there are waiting jobs but no running jobs, do something
464 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
466 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
468 * there's probably something wrong with having user mounts below /sys,
469 as we have for debugfs. for example, src/core/mount.c handles mounts
470 prefixed with /sys generally special.
471 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
473 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
475 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
477 * add a job mode that will fail if a transaction would mean stopping
478 running units. Use this in timedated to manage the NTP service
480 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
482 * The udev blkid built-in should expose a property that reflects
483 whether media was sensed in USB CF/SD card readers. This should then
484 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
485 picked up by systemd unless they contain a medium. This would mirror
486 the behaviour we already have for CD drives.
488 * networkd/udev: implement SR_IOV configuration in .link files:
489 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
491 * hostnamectl: show root image uuid
493 * Find a solution for SMACK capabilities stuff:
494 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
496 * "systemctl preset-all" should probably order the unit files it
497 operates on lexicographically before starting to work, in order to
498 ensure deterministic behaviour if two unit files conflict (like DMs
501 * synchronize console access with BSD locks:
502 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
504 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
505 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
507 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
509 * figure out when we can use the coarse timers
511 * add "systemctl start -v foobar.service" that shows logs of a service
512 while the start command runs. This is non-trivial to do without
513 races though, since we should flush out all journal messages before
514 returning from the "systemctl stop".
516 * firstboot: make it useful to be run immediately after yum --installroot to set up a machine. (most specifically, make --copy-root-password work even if /etc/passwd already exists
518 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
520 * maybe allow timer units with an empty Units= setting, so that they
521 can be used for resuming the system but nothing else.
523 * what to do about udev db binary stability for apps? (raw access is not an option)
525 * man: maybe use the word "inspect" rather than "introspect"?
527 * systemctl: if some operation fails, show log output?
529 * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
530 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
532 * exponential backoff in timesyncd when we cannot reach a server
534 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
536 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
538 * systemd.show_status= should probably have a mode where only failed
541 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
542 (throughout the codebase, not only PID1)
546 - service registration
547 - service/domain/types browsing
549 - DNS-SD service registration from socket units
550 - resolved should optionally register additional per-interface LLMNR
551 names, so that for the container case we can establish the same name
552 (maybe "host") for referencing the server, everywhere.
553 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
554 - hook up resolved with machined-based address resolution
556 * refcounting in sd-resolve is borked
558 * Add a new verb "systemctl top"
560 * add new gpt type for btrfs volumes
562 * support empty /etc boots nicely:
563 - nspawn/gpt-generator: introduce new gpt partition type for /usr
565 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
567 * a way for container managers to turn off getty starting via $container_headless= or so...
569 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
571 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
572 they run added to the initial transaction and thus confuse Type=idle.
574 * add bus api to query unit file's X fields.
576 * gpt-auto-generator:
577 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
578 - Make /home automount rather than mount?
580 * add generator that pulls in systemd-network from containers when
581 CAP_NET_ADMIN is set, more than the loopback device is defined, even
582 when it is otherwise off
584 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
586 * implement Distribute= in socket units to allow running multiple
587 service instances processing the listening socket, and open this up
590 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
591 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
592 should SIGSTOP all unit processes in a loop until all processes of
593 it are fully stopped. This can later be used for app management by
594 desktop UIs such as gnome-shell to freeze apps that are not visible
595 on screen, not unlike how job control works on the shell
598 - implement per-slice CPUFairScheduling=1 switch
599 - introduce high-level settings for RT budget, swappiness
600 - how to reset dynamically changed unit cgroup attributes sanely?
601 - when reloading configuration, apply new cgroup configuration
602 - when recursively showing the cgroup hierarchy, optionally also show
603 the hierarchies of child processes
606 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
608 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
610 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
612 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
614 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
616 * rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
618 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
620 * If we try to find a unit via a dangling symlink, generate a clean
621 error. Currently, we just ignore it and read the unit from the search
624 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
626 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
628 * load .d/*.conf dropins for device units
632 - GetAllProperties() on a non-existing object does not result in a failure currently
633 - port to sd-resolve for connecting to TCP dbus servers
634 - see if we can introduce a new sd_bus_get_owner_machine_id() call to retrieve the machine ID of the machine of the bus itself
635 - see if we can drop more message validation on the sending side
636 - add API to clone sd_bus_message objects
637 - longer term: priority inheritance
639 - NameLost/NameAcquired obsolete
642 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
645 - allow multiple signal handlers per signal?
646 - document chaining of signal handler for SIGCHLD and child handlers
647 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
648 - generate a failure of a default event loop is executed out-of-thread
650 * investigate endianness issues of UUID vs. GUID
652 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
653 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
655 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
657 * add a pam module that on password changes updates any LUKS slot where the password matches
660 - add unit tests for config_parse_device_allow()
662 * seems that when we follow symlinks to units we prefer the symlink
663 destination path over /etc and /usr. We should not do that. Instead
664 /etc should always override /run+/usr and also any symlink
667 * when isolating, try to figure out a way how we implicitly can order
668 all units we stop before the isolating unit...
670 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
672 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
673 that the boot loader should be installed to the ESP. Define a way
674 how an installer can figure out whether a BLS compliant boot loader
677 * think about requeuing jobs when daemon-reload is issued? usecase:
678 the initrd issues a reload after fstab from the host is accessible
679 and we might want to requeue the mounts local-fs acquired through
682 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
684 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
686 * shutdown logging: store to EFI var, and store to USB stick?
688 * merge unit_kill_common() and unit_kill_context()
691 - honor language efi variables for default language selection (if there are any?)
692 - honor timezone efi variables for default timezone selection (if there are any?)
693 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
695 - recognize the case when not booted on EFI
697 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
699 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
701 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
704 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
705 - logind: wakelock/opportunistic suspend support
706 - Add pretty name for seats in logind
707 - logind: allow showing logout dialog from system?
708 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
709 - if pam_systemd is invoked by su from a process that is outside of a
710 any session we should probably just become a NOP, since that's
711 usually not a real user session but just some system code that just
713 - logind: make the Suspend()/Hibernate() bus calls wait for the for
714 the job to be completed. before returning, so that clients can wait
715 for "systemctl suspend" to finish to know when the suspending is
717 - logind: when the power button is pressed short, just popup a
718 logout dialog. If it is pressed for 1s, do the usual
719 shutdown. Inspiration are Macs here.
720 - expose "Locked" property on logind sesison objects
721 - maybe allow configuration of the StopTimeout for session scopes
722 - rename session scope so that it includes the UID. THat way
723 the session scope can be arranged freely in slices and we don't have
724 make assumptions about their slice anymore.
725 - follow PropertiesChanged state more closely, to deal with quick logouts and
729 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
730 - import and delete pstore filesystem content at startup
731 - journald: also get thread ID from client, plus thread name
732 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
733 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
734 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
735 - declare the local journal protocol stable in the wiki interface chart
736 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
737 - journald: when dropping msgs due to ratelimit make sure to write
738 "dropped %u messages" not only when we are about to print the next
739 message that works, but already after a short timeout
740 - check if we can make journalctl by default use --follow mode inside of less if called without args?
741 - maybe add API to send pairs of iovecs via sd_journal_send
742 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
743 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
744 and !FOOBAR for events without FOOBAR.
745 - journal: store timestamp of journal_file_set_offline() int he header,
746 so it is possible to display when the file was last synced.
747 - journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
748 - journal: find a way to allow dropping history early, based on priority, other rules
749 - journal: When used on NFS, check payload hashes
750 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
751 - refuse taking lower-case variable names in sd_journal_send() and friends.
752 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
753 - journal: deal nicely with byte-by-byte copied files, especially regards header
754 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
755 - Replace utmp, wtmp, btmp, and lastlog completely with journal
756 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
757 - when a kernel driver logs in a tight loop, we should ratelimit that too.
758 - journald: optionally, log debug messages to /run but everything else to /var
759 - journald: when we drop syslog messages because the syslog socket is
760 full, make sure to write how many messages are lost as first thing
761 to syslog when it works again.
762 - change systemd-journal-flush into a service that stays around during
763 boot, and causes the journal to be moved back to /run on shutdown,
764 so that we do not keep /var busy. This needs to happen synchronously,
765 hence doing this via signals is not going to work.
766 - optionally support running journald from the command line for testing purposes in external projects
767 - journald: allow per-priority and per-service retention times when rotating/vacuuming
768 - journald: make use of uid-range.h to managed uid ranges to split
770 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
771 - improve journalctl performance by loading journal files
772 lazily. Encode just enough information in the file name, so that we
773 do not have to open it to know that it is not interesting for us, for
774 the most common operations.
775 - man: document that corrupted journal files is nothing to act on
776 - rework journald sigbus stuff to use mutex
777 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
778 services that run under their own user ids, and use User= (but only
779 in a world where userns is ubiquitous since otherwise we cannot
780 invoke those daemons on the host AND in a container anymore). Also,
781 if LimitNPROC= is used without User= we should warn and refuse
783 - journalctl --verify: don't show files that are currently being
784 written to as FAIL, but instead show that their are being written to.
785 - add journalctl -H that talks via ssh to a remote peer and passes through
787 - add a version of --merge which also merges /var/log/journal/remote
788 - journalctl: -m should access container journals directly by enumerating
789 them via machined, and also watch containers coming and going.
790 Benefit: nspawn --ephemeral would start working nicely with the journal.
791 - assign MESSAGE_ID to log messages about failed services
793 * add a test if all entries in the catalog are properly formatted.
794 (Adding dashes in a catalog entry currently results in the catalog entry
795 being silently skipped. journalctl --update-catalog must warn about this,
796 and we should also have a unit test to check that all our message are OK.)
799 - document that deps in [Unit] sections ignore Alias= fields in
800 [Install] units of other units, unless those units are disabled
801 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
802 - document that service reload may be implemented as service reexec
803 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
804 - document systemd-journal-flush.service properly
805 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
806 - man: document the very specific env the shutdown drop-in tools live in
807 - man: add more examples to man pages
808 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
809 - document root=gpt-auto properly
812 - add systemctl switch to dump transaction without executing it
813 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
814 - "systemctl disable" on a static unit prints no message and does
815 nothing. "systemctl enable" does nothing, and gives a bad message
816 about it. Should fix both to print nice actionable messages.
817 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
818 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
819 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
820 - systemctl: "Journal has been rotated since unit was started." message is misleading
821 - systemctl status output should include list of triggering units and their status
824 - "systemctl mask" should find all names by which a unit is accessible
825 (i.e. by scanning for symlinks to it) and link them all to /dev/null
828 - timer units should get the ability to trigger when:
830 - Modulate timer frequency based on battery state
832 * add libsystemd-password or so to query passwords during boot using the password agent logic
834 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
836 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
838 * make repeated alt-ctrl-del presses printing a dump
840 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
842 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
845 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
846 with seccomp. That should provide us with a useful log buffer that
847 systemd can log to during early boot, and disconnect container logs
848 from the kernel's logs.
849 - as soon as networkd has a bus interface, hook up --network-interface=,
850 --network-bridge= with networkd, to trigger netdev creation should an
852 - a nice way to boot up without machine id set, so that it is set at boot
853 automatically for supporting --ephemeral. Maybe hash the host machine id
854 together with the machine name to generate the machine id for the container
855 - fix logic always print a final newline on output.
856 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
857 - should optionally support receiving WATCHDOG=1 messages from its payload
859 - optionally automatically add FORWARD rules to iptables whenever nspawn is
860 running, remove them when shut down.
863 - refuse mounting over a mount point
864 - automatically discover .roothash files in dissect, similarly to nspawn
867 - add an API so that libvirt-lxc can inform us about network interfaces being
868 removed or added to an existing machine
869 - "machinectl migrate" or similar to copy a container from or to a
870 difference host, via ssh
871 - introduce systemd-nspawn-ephemeral@.service, and hook it into
872 "machinectl start" with a new --ephemeral switch
873 - "machinectl status" should also show internal logs of the container in
875 - "machinectl history"
877 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
878 shell in it, and marks it read-only after use
881 - cryptsetup-generator: allow specification of passwords in crypttab itself
882 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
884 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
885 https://bugs.freedesktop.org/show_bug.cgi?id=54712
887 * add a dependency on standard-conf.xml and other included files to man pages
889 * MountFlags=shared acts as MountFlags=slave right now.
891 * properly handle loop back mounts via fstab, especially regards to fsck/passno
893 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
898 - add trigger --subsystem-match=usb/usb_device device
899 - reimport udev db after MOVE events for devices without dev_t
901 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
903 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
906 - save coredump in Windows/Mozilla minidump format
907 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
909 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
911 * be able to specify a forced restart of service A where service B depends on, in case B
912 needs to be auto-respawned?
915 - apply "x" on "D" too (see patch from William Douglas)
917 - instead of ignoring unknown fields, reject them.
918 - creating new directories/subvolumes/fifos/device nodes
919 should not follow symlinks. None of the other adjustment or creation
920 calls follow symlinks.
922 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
924 * verify that the AF_UNIX sockets of a service in the fs still exist
925 when we start a service in order to avoid confusion when a user
926 assumes starting a service is enough to make it accessible
928 * Make it possible to set the keymap independently from the font on
929 the kernel cmdline. Right now setting one resets also the other.
931 * and a dbus call to generate target from current state
933 * write blog stories about:
934 - hwdb: what belongs into it, lsusb
935 - enabling dbus services
936 - how to make changes to sysctl and sysfs attributes
938 - how to pass throw-away units to systemd, or dynamically change properties of existing units
939 - testing with Harald's awesome test kit
941 - how to develop against journal browsing APIs
942 - the journal HTTP iface
943 - non-cgroup resource management
944 - dynamic resource management with cgroups
945 - refreshed, longer missions statement
946 - calendar time events
947 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
948 - how to create your own target
949 - instantiated apache, dovecot and so on
950 - hooking a script into various stages of shutdown/rearly booot
952 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
954 * dot output for --test showing the 'initial transaction'
957 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
958 log both units as UNIT=, so that journalctl -u triggers on both.
959 - generate better errors when people try to set transient properties
960 that are not supported...
961 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
962 - maybe introduce WantsMountsFor=? Usecase:
963 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
964 - recreate systemd's D-Bus private socket file on SIGUSR2
965 - move PAM code into its own binary
966 - when we automatically restart a service, ensure we restart its rdeps, too.
967 - hide PAM options in fragment parser when compile time disabled
968 - Support --test based on current system state
969 - If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
970 - after deserializing sockets in socket.c we should reapply sockopts and things
971 - drop PID 1 reloading, only do reexecing (difficult: Reload()
972 currently is properly synchronous, Reexec() is weird, because we
973 cannot delay the response properly until we are back, so instead of
974 being properly synchronous we just keep open the fd and close it
975 when done. That means clients do not get a successful method reply,
976 but much rather a disconnect on success.
977 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
978 - when a bus name of a service disappears from the bus make sure to queue further activation requests
981 - allow port=0 in .socket units
982 - maybe introduce ExecRestartPre=
983 - add ReloadSignal= for configuring a reload signal to use
984 - implement Register= switch in .socket units to enable registration
985 in Avahi, RPC and other socket registration services.
986 - allow Type=simple with PIDFile=
987 https://bugzilla.redhat.com/show_bug.cgi?id=723942
988 - allow writing multiple conditions in unit files on one line
989 - load-fragment: when loading a unit file via a chain of symlinks
990 verify that it is not masked via any of the names traversed.
991 - introduce Type=pid-file
992 - introduce mix of BindTo and Requisite
993 - add a concept of RemainAfterExit= to scope units
994 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
997 - Make sure ID_PATH is always exported and complete for
998 network devices where possible, so we can safely rely
1000 - check MTUBytes parsing (expecting size_t but we are using unsigned)
1003 - add support for more attribute types
1004 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1007 - add more keys to [Route] and [Address] sections
1008 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1009 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
1010 - add reduced [Link] support to .network files
1011 - add Scope= parsing option for [Network]
1012 - properly handle routerless dhcp leases
1013 - work with non-Ethernet devices
1014 - add support for more bond options
1015 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1016 - the DHCP lease data (such as NTP/DNS) is still made available when
1017 a carrier is lost on a link. It should be removed instantly.
1018 - expose in the API the following bits:
1019 - option 15, domain name and/or option 119, search list
1020 - option 12, host name and/or option 81, fqdn
1021 - option 123, 144, geolocation
1022 - option 252, configure http proxy (PAC/wpad)
1023 - provide a way to define a per-network interface default metric value
1024 for all routes to it. possibly a second default for DHCP routes.
1025 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1026 support Name=foo*|bar*|baz ?
1027 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1028 - allow DUID/IAID to be customized, see issue #394.
1029 - whenever uplink info changes, make DHCP server send out FORCERENEW
1031 * networkd-wait-online:
1032 - make operstates to wait for configurable?
1035 - figure out how much we can increase Maximum Message Size
1038 - add functions to set previously stored IPv6 addresses on startup and get
1039 them at shutdown; store them in client->ia_na
1040 - write more test cases
1041 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1042 - implement support for temporary adressess (IA_TA)
1043 - implement dhcpv6 authentication
1044 - investigate the usefulness of Confirm messages; i.e. are there any
1045 situations where the link changes without any loss in carrier detection
1047 - some servers don't do rapid commit without a filled in IA_NA, verify
1054 - natively watch for dbus-*.service symlinks (PENDING)
1055 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1057 * fix alsa mixer restore to not print error when no config is stored
1059 * make cryptsetup lower --iter-time
1061 * patch kernel for xattr support in /dev, /proc/, /sys?
1063 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1065 * /usr/bin/service should actually show the new command line
1067 * 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=
1069 * fedora: F20: go timer units all the way, leave cron.daily for cron
1071 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1073 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1075 * register catalog database signature as file magic
1077 * zsh shell completion:
1078 - <command> <verb> -<TAB> should complete options, but currently does not
1079 - systemctl add-wants,add-requires
1084 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1086 * check for strerror(r) instead of strerror(-r)
1090 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1092 * use secure_getenv() instead of getenv() where appropriate
1094 * link up selected blog stories from man pages and unit files Documentation= fields
1095 String is not UTF-8 clean, ignoring assignment
1096 timedatex.service: Consumed 26ms CPU time.
