3 * copy.c: set the right chattrs before copying files and others after
5 * Many manager configuration settings that are only applicable to user
6 manager or system manager can be always set. It would be better to reject
7 them when parsing config.
9 * Clarify what IPAddress* matches (source, destination, both?)
13 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
15 * wiki: update journal format documentation for lz4 additions
19 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
21 * rework mount.c and swap.c to follow proper state enumeration/deserialization
22 semantics, like we do for device.c now
26 * when we fork off generators and such, lower LIMIT_NOFILE soft limit to 1K
28 * add a concept for automatically loading per-unit secrets off disk and
29 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
30 ConfigurationDirectory=.
32 * systemd-gpt-auto: if we find the root dir mounted read-only and the gpt flag
33 doesn't say so generate job that remounts it writable
35 * when no locale is configured, default to UEFI's PlatformLang variable
37 * When logind.conf contains HandleLidSwitch=suspend-then-hibernate and we can't
38 hibernate because the swap partition isn't large enough, still suspend
40 * bootctl: implement Type #2 boot loader entry discovery
42 * bootctl,sd-boot: actually honour the "architecture" key
44 * consider splitting out all temporary file creation APIs (we have so many in
45 fileio.h and elsewhere!) into a new util file of its own.
47 * set memory.oom.group in cgroupsv2 for all leaf cgroups (kernel v4.19+)
49 * drop umask() calls and suchlike from our generators, pid1 should set things up correctly anyway
51 * paranoia: whenever we process passwords, call mlock() on the memory
52 first. i.e. look for all places we use string_erase()/string_free_erase() and
53 augment them with mlock()
55 * whenever oom_kill memory.event event is triggered print a nice log message
57 * Move RestrictAddressFamily= to the new cgroup create socket
59 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
62 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
63 log.c and sd-journal-send
65 * chown() tty a service is attached to after the service goes down
67 * optionally: turn on cgroup delegation for per-session scope units
69 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
71 * optionally, if a per-partition GPT flag is set for the root/home/… partitions
72 format the partition on next boot and unset the flag, in order to implement
73 factory reset. also, add a second flag that simply indicates whether such a
74 scheme is supported. then, add a tool (or maybe beef up systemd-dissect) to
75 show state of these flags, and optionally trigger such a factory reset on
76 next boot by setting the flag.
78 * sd-boot: search drop-ins in $BOOT, too
80 * sd-boot: add "oneshot boot timeout" variable support
82 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
83 can add in file system drivers and such
85 * esp generator: also mount $BOOT if found
87 * sd-boot: optionally, show boot menu when previous default boot item has
88 non-zero "tries done" count
90 * logind: add "boot into bootmenu" API, and possibly even "boot into windows"
91 and "boot into macos".
93 * bootspec.c: also enumerate EFI unified kernel images.
95 * maybe extend .path units to expose fanotify() per-mount change events
97 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
98 output of "systemctl list-units" slightly by showing the tree structure of
99 the slices, and the units attached to them.
101 * the a-posteriori stopping of units bound to units that disappeared logic
102 should be reworked: there should be a queue of units, and we should only
103 enqeue stop jobs from a defer event that processes queue instead of
104 right-away when we find a unit that is bound to one that doesn't exist
105 anymore. (similar to how the stop-unneeded queue has been reworked the same
108 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
109 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
110 for hangup or ^D before passing on the EOF.
112 * When reloading configuration PID 1 should reset all its properties to the
113 original defaults before calling parse_config()
115 * Add OnTimezoneChange= and OnTimeChange= stanzas to .timer units in order to
116 schedule events based on time and timezone changes.
118 * nspawn: greater control over selinux label?
120 * cgroups: figure out if we can somehow communicate in a cleaner way whether a
121 systemd instance not running in the cgroup root shall or shall not manage the
122 attributes of its top-level cgroup. Currently it assumes it manages all, but
123 then might get EPERM due to permission porblems/userns, which is OK, but this
124 should be revisited to make clearer and also work if the payload systemd runs
125 with full privs and without userns.
127 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
130 1. add resume_offset support to the resume code (i.e. support swap files
132 2. check if swap is on weird storage and refuse if so
133 3. add autodetection of hibernation images
135 * cgroups: use inotify to get notified when somebody else modifies cgroups
136 owned by us, then log a friendly warning.
138 * beef up log.c with support for stripping ANSI sequences from strings, so that
139 it is OK to include them in log strings. This would be particularly useful so
140 that our log messages could contain clickable links for example for unit
141 files and suchlike we operate on.
143 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
145 * add attach --enable and attach --now (for attach+enable+start)
147 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
148 selected user is resolvable in the service even if it ships its own /etc/passwd)
150 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
151 other doesn't. What a desaster. Probably to exclude it. Also
152 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
155 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
156 usually IN_ATTRIB is the right way to watch deleted files, as the former only
157 fires when a file is actually removed from disk, i.e. the link count drops to
158 zero and is not open anymore, while the latter happens when a file is
159 unlinked from any dir.
161 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
163 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
165 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
167 * SuccessExitStatus= and friends should probably also accept symbolic exit
168 codes names, i.e. error codes from the list maintained in exit-codes.[ch]
170 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
171 files and directories that are left writable for a unit, and which are
172 removed after the unit goes down again. A bit like --ephemeral for
173 systemd-nspawn but for system services. If used together with RootImage= this
174 should reflink the image file itself.
176 Related: add Ephemeral=<path1> <path2> … which would allow marking
177 specific paths only like this.
179 * add CopyFile= or so as unit file setting that may be used to copy files or
180 directory trees from the host to te services RootImage= and RootDirectory=
181 environment. Which we can use for /etc/machine-id and in particular
182 /etc/resolv.conf. Should be smart and do something useful on read-only
183 images, for example fallback to read-only bind mounting the file instead.
185 * nspawn's console TTY should be allocated from within the container, not
186 mounted in from the outside
188 * show invocation ID in systemd-run output
190 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
192 * tree-wide: ensure we always block the signals we hook into with
193 sd_event_add_signal() first
195 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
196 and so on, which would mean we could report errors and such.
198 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
201 * introduce DefaultSlice= or so in system.conf that allows changing where we
202 place our units by default, i.e. change system.slice to something
203 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
204 be moved somewhere else too. Finally machined and logind should get similar
205 options so that it is possible to move user session scopes and machines to a
206 different slice too by default. Usecase: people who want to put resources on
207 the entire system, with the exception of one specific service. See:
208 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
210 * maybe rework get_user_creds() to query the user database if $SHELL is used
211 for root, but only then.
213 * be stricter with fds we receive for the fdstore: close them asynchronously
215 * calenderspec: add support for week numbers and day numbers within a
216 year. This would allow us to define "bi-weekly" triggers safely.
218 * sd-bus: add vtable flag, that may be used to request client creds implicitly
219 and asynchronously before dispatching the operation
221 * make use of ethtool veth peer info in machined, for automatically finding out
222 host-side interface pointing to the container.
224 * add some special mode to LogsDirectory=/StateDirectory=… that allows
225 declaring these directories without necessarily pulling in deps for them, or
226 creating them when starting up. That way, we could declare that
227 systemd-journald writes to /var/log/journal, which could be useful when we
228 doing disk usage calculations and so on.
230 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
232 * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
234 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
235 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
236 as the unit is running or has a job queued.
238 * support projid-based quota in machinectl for containers
240 * Add NetworkNamespacePath= to specify a path to a network namespace
242 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
243 introduced) as the RTC epoch, instead of the mtime of NEWS.
245 * add a way to lock down cgroup migration: a boolean, which when set for a unit
246 makes sure the processes in it can never migrate out of it
248 * blog about fd store and restartable services
250 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
252 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
253 magic meaning and is no longer upgraded to something else if set explicitly.
255 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
256 make it lose its identity, i.e. be anonymous. For this we'd have to patch
257 through the whole tree to make all code deal with the case where no machine
260 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
261 suitable for processing with rrdtool. Add bus API to access this data, and
262 possibly implement a CPULoad property based on it.
264 * beef up pam_systemd to take unit file settings such as cgroups properties as
267 * a new "systemd-analyze security" tool outputting a checklist of security
268 features a service does and does not implement
270 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
271 the quota of a the user indicated in User= via unit file settings, like the
272 other resource management concepts. Would mix nicely with DynamicUser=1. Or
273 alternatively, do this with projids, so that we can also cover services
274 running as root. Quota should probably cover all the special dirs such as
275 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
276 is set, plus the whole disk space any image configured with RootImage=.
278 * Introduce "exit" as an EmergencyAction value, and allow to configure a
279 per-unit success/failure exit code to configure. This would be useful for
280 running commands inside of services inside of containers, which could then
281 propagate their failure state all the way up.
283 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
284 disks to see if the UID is already in use.
286 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
287 for all units. It should be both a way to pin units into memory as well as a
288 wait to retrieve their exit data.
290 * expose IO accounting data on the bus, show it in systemd-run --wait and log
291 about it in the resource log message
293 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
294 unit when it is stopped
296 * show whether a service has out-of-date configuration in "systemctl status" by
297 using mtime data of ConfigurationDirectory=.
299 * replace all uses of fgets() + LINE_MAX by read_line()
301 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
302 creates a static, persistent user rather than a dynamic, transient user. We
303 can leverage code from sysusers.d for this.
305 * add some optional flag to ReadWritePaths= and friends, that has the effect
306 that we create the dir in question when the service is started. Example:
308 ReadWritePaths=:/var/lib/foobar
310 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
311 the sd-journal logging socket, and, if the timeout is set to 0, sets
312 O_NONBLOCK on it. That way people can control if and when to block for
315 * hostnamed: populate form factor data from a new hwdb database, so that old
316 yogas can be recognized as "convertible" too, even if they predate the DMI
317 "convertible" form factor
319 * Maybe add a small tool invoked early at boot, that adds in or resizes
320 partitions automatically, to be used when the media used is actually larger
321 than the image written onto it is.
323 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
324 after all. Be strict however, only support the equivalent of nspawn's
325 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
328 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
329 the service cgroup, which is supposed to monitor the service, and when it
330 exits the service is considered failed by its monitor.
332 * track the per-service PAM process properly (i.e. as an additional control
333 process), so that it may be queried on the bus and everything.
335 * add a new "debug" job mode, that is propagated to unit_start() and for
336 services results in two things: we raise SIGSTOP right before invoking
337 execve() and turn off watchdog support. Then, use that to implement
338 "systemd-gdb" for attaching to the start-up of any system service in its
341 * maybe introduce gpt auto discovery for /var/tmp?
343 * maybe add gpt-partition-based user management: each user gets his own
344 LUKS-encrypted GPT partition with a new GPT type. A small nss module
345 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
346 way: the partition index is added as offset to some fixed base uid. User name
347 is stored in GPT partition name. A PAM module authenticates the user via the
348 LUKS partition password. Benefits: strong per-user security, compatibility
349 with stateless/read-only/verity-enabled root. (other idea: do this based on
350 loopback files in /home, without GPT involvement)
352 * gpt-auto logic: introduce support for discovering /var matching an image. For
353 that, use a partition type UUID that is hashed from the OS name (as encoded
354 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
355 field of the root partition. This way can easily support multiple OS
356 installations on the same GPT partition table, without problems with
357 unmatched /var partitions.
359 * gpt-auto logic: related to the above, maybe support a "secondary" root
360 partition, that is mounted to / and is writable, and where the actual root's
361 /usr is mounted into.
363 * 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
365 * drop nss-myhostname in favour of nss-resolve?
367 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
368 then use that for the setting used in user@.service. It should be understood
369 relative to the configured default value.
371 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
373 * enable LockMLOCK to take a percentage value relative to physical memory
375 * Permit masking specific netlink APIs with RestrictAddressFamily=
377 * nspawn: support that /proc, /sys/, /dev are pre-mounted
379 * define gpt header bits to select volatility mode
381 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
383 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
385 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
387 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
389 * ProtectKeyRing= to take keyring calls away
391 * RemoveKeyRing= to remove all keyring entries of the specified user
393 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
394 on PID 1 with the relevant signals, and makes relevant files in /sys and
395 /proc (such as the sysrq stuff) unavailable
397 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
399 * journalctl: make sure -f ends when the container indicated by -M terminates
401 * mount: automatically search for "main" partition of an image has multiple
404 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
407 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
408 find a way to map the User=/Group= of the service to the right name. This way
409 a user/group for a service only has to exist on the host for the right
412 * add bus API for creating unit files in /etc, reusing the code for transient units
414 * add bus API to remove unit files from /etc
416 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
418 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
419 kernel doesn't support linkat() that replaces existing files, currently)
421 * transient units: don't bother with actually setting unit properties, we
422 reload the unit file anyway
424 * journald: sigbus API via a signal-handler safe function that people may call
425 from the SIGBUS handler
427 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
429 * resolved: when routing queries, make sure only look for the *longest* suffix...
431 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
432 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
434 * cache sd_event_now() result from before the first iteration...
436 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
438 * PID1: find a way how we can reload unit file configuration for
439 specific units only, without reloading the whole of systemd
441 * add an explicit parser for LimitRTPRIO= that verifies
442 the specified range and generates sane error messages for incorrect
445 * when we detect that there are waiting jobs but no running jobs, do something
447 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
449 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
451 * there's probably something wrong with having user mounts below /sys,
452 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
453 prefixed with /sys generally special.
454 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
456 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
458 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
460 * add a job mode that will fail if a transaction would mean stopping
461 running units. Use this in timedated to manage the NTP service
463 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
465 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
466 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
468 * The udev blkid built-in should expose a property that reflects
469 whether media was sensed in USB CF/SD card readers. This should then
470 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
471 picked up by systemd unless they contain a medium. This would mirror
472 the behaviour we already have for CD drives.
474 * networkd/udev: implement SR_IOV configuration in .link files:
475 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
477 * hostnamectl: show root image uuid
479 * Find a solution for SMACK capabilities stuff:
480 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
482 * "systemctl preset-all" should probably order the unit files it
483 operates on lexicographically before starting to work, in order to
484 ensure deterministic behaviour if two unit files conflict (like DMs
487 * synchronize console access with BSD locks:
488 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
490 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
491 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
493 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
495 * figure out when we can use the coarse timers
497 * add "systemctl start -v foobar.service" that shows logs of a service
498 while the start command runs. This is non-trivial to do without
499 races though, since we should flush out all journal messages before
500 returning from the "systemctl stop".
502 * 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
504 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
506 * consider showing the unit names during boot up in the status output, not just the unit descriptions
508 * maybe allow timer units with an empty Units= setting, so that they
509 can be used for resuming the system but nothing else.
511 * what to do about udev db binary stability for apps? (raw access is not an option)
513 * man: maybe use the word "inspect" rather than "introspect"?
515 * systemctl: if some operation fails, show log output?
517 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
518 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
520 * exponential backoff in timesyncd when we cannot reach a server
522 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
524 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
526 * systemd.show_status= should probably have a mode where only failed
529 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
530 (throughout the codebase, not only PID1)
534 - service registration
535 - service/domain/types browsing
537 - DNS-SD service registration from socket units
538 - resolved should optionally register additional per-interface LLMNR
539 names, so that for the container case we can establish the same name
540 (maybe "host") for referencing the server, everywhere.
541 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
542 - hook up resolved with machined-based address resolution
544 * refcounting in sd-resolve is borked
546 * Add a new verb "systemctl top"
548 * add new gpt type for btrfs volumes
550 * support empty /etc boots nicely:
551 - nspawn/gpt-generator: introduce new gpt partition type for /usr
553 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
555 * a way for container managers to turn off getty starting via $container_headless= or so...
557 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
559 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
560 they run added to the initial transaction and thus confuse Type=idle.
562 * add bus api to query unit file's X fields.
564 * gpt-auto-generator:
565 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
566 - Make /home automount rather than mount?
568 * add generator that pulls in systemd-network from containers when
569 CAP_NET_ADMIN is set, more than the loopback device is defined, even
570 when it is otherwise off
572 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
574 * implement Distribute= in socket units to allow running multiple
575 service instances processing the listening socket, and open this up
578 * socket units: support creating sockets in different namespace,
579 opening it up for JoinsNamespaceOf=. This would require to fork off
580 a tiny process that joins the namespace and creates/binds the socket
581 and passes this back to PID1 via SCM_RIGHTS. This also could be used
582 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
584 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
585 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
586 should SIGSTOP all unit processes in a loop until all processes of
587 it are fully stopped. This can later be used for app management by
588 desktop UIs such as gnome-shell to freeze apps that are not visible
589 on screen, not unlike how job control works on the shell
592 - implement per-slice CPUFairScheduling=1 switch
593 - handle jointly mounted controllers correctly
594 - introduce high-level settings for RT budget, swappiness
595 - how to reset dynamically changed unit cgroup attributes sanely?
596 - when reloading configuration, apply new cgroup configuration
597 - when recursively showing the cgroup hierarchy, optionally also show
598 the hierarchies of child processes
601 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
603 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
605 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
607 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
609 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
611 * 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
613 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
615 * If we try to find a unit via a dangling symlink, generate a clean
616 error. Currently, we just ignore it and read the unit from the search
619 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
621 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
623 * load .d/*.conf dropins for device units
625 * allow implementation of InaccessibleDirectories=/ plus
626 ReadOnlyDirectories=... for whitelisting files for a service.
630 - GetAllProperties() on a non-existing object does not result in a failure currently
631 - port to sd-resolve for connecting to TCP dbus servers
632 - 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
633 - see if we can drop more message validation on the sending side
634 - add API to clone sd_bus_message objects
635 - longer term: priority inheritance
637 - NameLost/NameAcquired obsolete
640 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
643 - allow multiple signal handlers per signal?
644 - document chaining of signal handler for SIGCHLD and child handlers
645 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
646 - generate a failure of a default event loop is executed out-of-thread
648 * investigate endianness issues of UUID vs. GUID
650 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
651 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
653 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
655 * add a pam module that on password changes updates any LUKS slot where the password matches
657 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
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()
690 * introduce ExecCondition= in services
693 - honor language efi variables for default language selection (if there are any?)
694 - honor timezone efi variables for default timezone selection (if there are any?)
695 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
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
728 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
731 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
732 - import and delete pstore filesystem content at startup
733 - journald: also get thread ID from client, plus thread name
734 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
735 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
736 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
737 - declare the local journal protocol stable in the wiki interface chart
738 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
739 - journald: when dropping msgs due to ratelimit make sure to write
740 "dropped %u messages" not only when we are about to print the next
741 message that works, but alraedy after a short tiemout
742 - check if we can make journalctl by default use --follow mode inside of less if called without args?
743 - maybe add API to send pairs of iovecs via sd_journal_send
744 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
745 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
746 and !FOOBAR for events without FOOBAR.
747 - journal: store timestamp of journal_file_set_offline() int he header,
748 so it is possible to display when the file was last synced.
749 - 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.
750 - journal: find a way to allow dropping history early, based on priority, other rules
751 - journal: When used on NFS, check payload hashes
752 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
753 - refuse taking lower-case variable names in sd_journal_send() and friends.
754 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
755 - journal: deal nicely with byte-by-byte copied files, especially regards header
756 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
757 - Replace utmp, wtmp, btmp, and lastlog completely with journal
758 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
759 - when a kernel driver logs in a tight loop, we should ratelimit that too.
760 - journald: optionally, log debug messages to /run but everything else to /var
761 - journald: when we drop syslog messages because the syslog socket is
762 full, make sure to write how many messages are lost as first thing
763 to syslog when it works again.
764 - change systemd-journal-flush into a service that stays around during
765 boot, and causes the journal to be moved back to /run on shutdown,
766 so that we do not keep /var busy. This needs to happen synchronously,
767 hence doing this via signals is not going to work.
768 - optionally support running journald from the command line for testing purposes in external projects
769 - journald: allow per-priority and per-service retention times when rotating/vacuuming
770 - journald: make use of uid-range.h to managed uid ranges to split
772 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
773 - improve journalctl performance by loading journal files
774 lazily. Encode just enough information in the file name, so that we
775 do not have to open it to know that it is not interesting for us, for
776 the most common operations.
777 - man: document that corrupted journal files is nothing to act on
778 - rework journald sigbus stuff to use mutex
779 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
780 services that run under their own user ids, and use User= (but only
781 in a world where userns is ubiquitous since otherwise we cannot
782 invoke those daemons on the host AND in a container anymore). Also,
783 if LimitNPROC= is used without User= we should warn and refuse
785 - journalctl --verify: don't show files that are currently being
786 written to as FAIL, but instead show that their are being written to.
787 - add journalctl -H that talks via ssh to a remote peer and passes through
789 - add a version of --merge which also merges /var/log/journal/remote
790 - journalctl: -m should access container journals directly by enumerating
791 them via machined, and also watch containers coming and going.
792 Benefit: nspawn --ephemeral would start working nicely with the journal.
793 - assign MESSAGE_ID to log messages about failed services
795 * add a test if all entries in the catalog are properly formatted.
796 (Adding dashes in a catalog entry currently results in the catalog entry
797 being silently skipped. journalctl --update-catalog must warn about this,
798 and we should also have a unit test to check that all our message are OK.)
801 - document that deps in [Unit] sections ignore Alias= fields in
802 [Install] units of other units, unless those units are disabled
803 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
804 - document that service reload may be implemented as service reexec
805 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
806 - document systemd-journal-flush.service properly
807 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
808 - man: document the very specific env the shutdown drop-in tools live in
809 - man: add more examples to man pages
810 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
813 - add systemctl switch to dump transaction without executing it
814 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
815 - "systemctl disable" on a static unit prints no message and does
816 nothing. "systemctl enable" does nothing, and gives a bad message
817 about it. Should fix both to print nice actionable messages.
818 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
819 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
820 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
821 - systemctl: "Journal has been rotated since unit was started." message is misleading
822 - systemctl status output should include list of triggering units and their status
825 - "systemctl mask" should find all names by which a unit is accessible
826 (i.e. by scanning for symlinks to it) and link them all to /dev/null
829 - timer units should get the ability to trigger when:
830 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
833 - Modulate timer frequency based on battery state
835 * add libsystemd-password or so to query passwords during boot using the password agent logic
837 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
839 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
841 * make repeated alt-ctrl-del presses printing a dump
843 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
845 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
848 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
849 with seccomp. That should provide us with a useful log buffer that
850 systemd can log to during early boot, and disconnect container logs
851 from the kernel's logs.
852 - as soon as networkd has a bus interface, hook up --network-interface=,
853 --network-bridge= with networkd, to trigger netdev creation should an
855 - a nice way to boot up without machine id set, so that it is set at boot
856 automatically for supporting --ephemeral. Maybe hash the host machine id
857 together with the machine name to generate the machine id for the container
858 - fix logic always print a final newline on output.
859 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
860 - should optionally support receiving WATCHDOG=1 messages from its payload
862 - optionally automatically add FORWARD rules to iptables whenever nspawn is
863 running, remove them when shut down.
864 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
868 - refuse mounting over a mount point
869 - automatically discover .roothash files in dissect, similarly to nspawn
872 - add an API so that libvirt-lxc can inform us about network interfaces being
873 removed or added to an existing machine
874 - "machinectl migrate" or similar to copy a container from or to a
875 difference host, via ssh
876 - introduce systemd-nspawn-ephemeral@.service, and hook it into
877 "machinectl start" with a new --ephemeral switch
878 - "machinectl status" should also show internal logs of the container in
880 - "machinectl history"
882 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
883 shell in it, and marks it read-only after use
886 - cryptsetup-generator: allow specification of passwords in crypttab itself
887 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
889 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
890 https://bugs.freedesktop.org/show_bug.cgi?id=54712
892 * add a dependency on standard-conf.xml and other included files to man pages
894 * MountFlags=shared acts as MountFlags=slave right now.
896 * properly handle loop back mounts via fstab, especially regards to fsck/passno
898 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
903 - add trigger --subsystem-match=usb/usb_device device
904 - reimport udev db after MOVE events for devices without dev_t
906 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
908 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
911 - save coredump in Windows/Mozilla minidump format
912 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
914 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
916 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
918 * be able to specify a forced restart of service A where service B depends on, in case B
919 needs to be auto-respawned?
922 - apply "x" on "D" too (see patch from William Douglas)
924 - instead of ignoring unknown fields, reject them.
925 - creating new directories/subvolumes/fifos/device nodes
926 should not follow symlinks. None of the other adjustment or creation
927 calls follow symlinks.
929 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
931 * verify that the AF_UNIX sockets of a service in the fs still exist
932 when we start a service in order to avoid confusion when a user
933 assumes starting a service is enough to make it accessible
935 * Make it possible to set the keymap independently from the font on
936 the kernel cmdline. Right now setting one resets also the other.
938 * and a dbus call to generate target from current state
940 * write blog stories about:
941 - hwdb: what belongs into it, lsusb
942 - enabling dbus services
943 - how to make changes to sysctl and sysfs attributes
945 - how to pass throw-away units to systemd, or dynamically change properties of existing units
946 - testing with Harald's awesome test kit
948 - how to develop against journal browsing APIs
949 - the journal HTTP iface
950 - non-cgroup resource management
951 - dynamic resource management with cgroups
952 - refreshed, longer missions statement
953 - calendar time events
954 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
955 - how to create your own target
956 - instantiated apache, dovecot and so on
957 - hooking a script into various stages of shutdown/rearly booot
959 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
961 * dot output for --test showing the 'initial transaction'
964 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
965 log both units as UNIT=, so that journalctl -u triggers on both.
966 - generate better errors when people try to set transient properties
967 that are not supported...
968 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
969 - maybe introduce WantsMountsFor=? Usecase:
970 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
971 - recreate systemd's D-Bus private socket file on SIGUSR2
972 - move PAM code into its own binary
973 - when we automatically restart a service, ensure we restart its rdeps, too.
974 - hide PAM options in fragment parser when compile time disabled
975 - Support --test based on current system state
976 - 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().
977 - after deserializing sockets in socket.c we should reapply sockopts and things
978 - drop PID 1 reloading, only do reexecing (difficult: Reload()
979 currently is properly synchronous, Reexec() is weird, because we
980 cannot delay the response properly until we are back, so instead of
981 being properly synchronous we just keep open the fd and close it
982 when done. That means clients do not get a successful method reply,
983 but much rather a disconnect on success.
984 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
985 - when a bus name of a service disappears from the bus make sure to queue further activation requests
988 - allow port=0 in .socket units
989 - maybe introduce ExecRestartPre=
990 - add ReloadSignal= for configuring a reload signal to use
991 - implement Register= switch in .socket units to enable registration
992 in Avahi, RPC and other socket registration services.
993 - allow Type=simple with PIDFile=
994 https://bugzilla.redhat.com/show_bug.cgi?id=723942
995 - allow writing multiple conditions in unit files on one line
996 - load-fragment: when loading a unit file via a chain of symlinks
997 verify that it is not masked via any of the names traversed.
998 - introduce Type=pid-file
999 - introduce mix of BindTo and Requisite
1000 - add a concept of RemainAfterExit= to scope units
1001 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1004 - Make sure ID_PATH is always exported and complete for
1005 network devices where possible, so we can safely rely
1007 - check MTUBytes parsing (expecting size_t but we are using unsigned)
1010 - add support for more attribute types
1011 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1014 - add more keys to [Route] and [Address] sections
1015 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1016 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
1017 - add reduced [Link] support to .network files
1018 - add Scope= parsing option for [Network]
1019 - properly handle routerless dhcp leases
1020 - work with non-Ethernet devices
1021 - add support for more bond options
1022 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1023 - the DHCP lease data (such as NTP/DNS) is still made available when
1024 a carrier is lost on a link. It should be removed instantly.
1025 - expose in the API the following bits:
1026 - option 15, domain name and/or option 119, search list
1027 - option 12, host name and/or option 81, fqdn
1028 - option 123, 144, geolocation
1029 - option 252, configure http proxy (PAC/wpad)
1030 - provide a way to define a per-network interface default metric value
1031 for all routes to it. possibly a second default for DHCP routes.
1032 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1033 support Name=foo*|bar*|baz ?
1034 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1035 - allow DUID/IAID to be customized, see issue #394.
1036 - whenever uplink info changes, make DHCP server send out FORCERENEW
1038 * networkd-wait-online:
1039 - make operstates to wait for configurable?
1042 - figure out how much we can increase Maximum Message Size
1045 - add functions to set previously stored IPv6 addresses on startup and get
1046 them at shutdown; store them in client->ia_na
1047 - write more test cases
1048 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1049 - implement support for temporary adressess (IA_TA)
1050 - implement dhcpv6 authentication
1051 - investigate the usefulness of Confirm messages; i.e. are there any
1052 situations where the link changes without any loss in carrier detection
1054 - some servers don't do rapid commit without a filled in IA_NA, verify
1061 - natively watch for dbus-*.service symlinks (PENDING)
1062 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1064 * fix alsa mixer restore to not print error when no config is stored
1066 * make cryptsetup lower --iter-time
1068 * patch kernel for xattr support in /dev, /proc/, /sys?
1070 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1072 * /usr/bin/service should actually show the new command line
1074 * 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=
1076 * fedora: F20: go timer units all the way, leave cron.daily for cron
1078 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1080 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1082 * register catalog database signature as file magic
1084 * zsh shell completion:
1085 - <command> <verb> -<TAB> should complete options, but currently does not
1086 - systemctl add-wants,add-requires
1091 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1093 * check for strerror(r) instead of strerror(-r)
1097 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1099 * use secure_getenv() instead of getenv() where appropriate
1101 * link up selected blog stories from man pages and unit files Documentation= fields
