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.
11 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
13 * wiki: update journal format documentation for lz4 additions
17 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
19 * rework mount.c and swap.c to follow proper state enumeration/deserialization
20 semantics, like we do for device.c now
24 * add a concept for automatically loading per-unit secrets off disk and
25 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
26 ConfigurationDirectory=.
28 * systemd-gpt-auto: if we find the root dir mounted read-only and the gpt flag
29 doesn't say so generate job that remounts it writable
31 * When logind.conf contains HandleLidSwitch=suspend-then-hibernate and we can't
32 hibernate because the swap partition isn't large enough, still suspend
34 * Now that C.UTF-8 is standardized in glibc, default to it if locale.conf
35 doesn't set anything otherwise
37 * bootctl: implement Type #2 boot loader entry discovery
39 * bootctl,sd-boot: actually honour the "architecture" key
41 * consider splitting out all temporary file creation APIs (we have so many in
42 fileio.h and elsewhere!) into a new util file of its own.
44 * set memory.oom.group in cgroupsv2 for all leaf cgroups
46 * drop umask() calls and suchlike from our generators, pid1 should set things up correctly anyway
48 * paranoia: whenever we process passwords, call mlock() on the memory
49 first. i.e. look for all places we use string_erase()/string_free_erase() and
50 augment them with mlock()
52 * whenever oom_kill memory.event event is triggered print a nice log message
54 * Move RestrictAddressFamily= to the new cgroup create socket
56 * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
59 * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
60 log.c and sd-journal-send
62 * chown() tty a service is attached to after the service goes down
64 * optionally: turn on cgroup delegation for per-session scope units
66 * introduce per-unit (i.e. per-slice, per-service) journal log size limits.
68 * optionally, if a per-partition GPT flag is set for the root/home/… partitions
69 format the partition on next boot and unset the flag, in order to implement
70 factory reset. also, add a second flag that simply indicates whether such a
71 scheme is supported. then, add a tool (or maybe beef up systemd-dissect) to
72 show state of these flags, and optionally trigger such a factory reset on
73 next boot by setting the flag.
75 * sd-boot: search drop-ins in $BOOT, too
77 * sd-boot: add "oneshot boot timeout" variable support
79 * sd-boot: automatically load EFI modules from some drop-in dir, so that people
80 can add in file system drivers and such
82 * esp generator: also mount $BOOT if found
84 * sd-boot: optionally, show boot menu when previous default boot item has
85 non-zero "tries done" count
87 * logind: add "boot into bootmenu" API, and possibly even "boot into windows"
88 and "boot into macos".
90 * bootspec.c: also enumerate EFI unified kernel images.
92 * maybe extend .path units to expose fanotify() per-mount change events
94 * Add a "systemctl list-units --by-slice" mode or so, which rearranges the
95 output of "systemctl list-units" slightly by showing the tree structure of
96 the slices, and the units attached to them.
98 * the a-posteriori stopping of units bound to units that disappeared logic
99 should be reworked: there should be a queue of units, and we should only
100 enqeue stop jobs from a defer event that processes queue instead of
101 right-away when we find a unit that is bound to one that doesn't exist
102 anymore. (similar to how the stop-unneeded queue has been reworked the same
105 * nspawn: make nspawn suitable for shell pipelines: instead of triggering a
106 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
107 for hangup or ^D before passing on the EOF.
109 * When reloading configuration PID 1 should reset all its properties to the
110 original defaults before calling parse_config()
112 * Add OnTimezoneChange= and OnTimeChange= stanzas to .timer units in order to
113 schedule events based on time and timezone changes.
115 * nspawn: greater control over selinux label?
117 * cgroups: figure out if we can somehow communicate in a cleaner way whether a
118 systemd instance not running in the cgroup root shall or shall not manage the
119 attributes of its top-level cgroup. Currently it assumes it manages all, but
120 then might get EPERM due to permission porblems/userns, which is OK, but this
121 should be revisited to make clearer and also work if the payload systemd runs
122 with full privs and without userns.
124 * hibernate/s2h: make this robust and safe to enable in Fedora by default.
127 1. add resume_offset support to the resume code (i.e. support swap files
129 2. check if swap is on weird storage and refuse if so
130 3. add autodetection of hibernation images
132 * cgroups: use inotify to get notified when somebody else modifies cgroups
133 owned by us, then log a friendly warning.
135 * beef up log.c with support for stripping ANSI sequences from strings, so that
136 it is OK to include them in log strings. This would be particularly useful so
137 that our log messages could contain clickable links for example for unit
138 files and suchlike we operate on.
140 * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
142 * add attach --enable and attach --now (for attach+enable+start)
144 * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
145 selected user is resolvable in the service even if it ships its own /etc/passwd)
147 * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
148 other doesn't. What a desaster. Probably to exclude it. Also
149 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
152 * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
153 usually IN_ATTRIB is the right way to watch deleted files, as the former only
154 fires when a file is actually removed from disk, i.e. the link count drops to
155 zero and is not open anymore, while the latter happens when a file is
156 unlinked from any dir.
158 * port systemctl, busctl, … over to format-table.[ch]'s table formatters
160 * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
162 * add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
164 * SuccessExitStatus= and friends should probably also accept symbolic exit
165 codes names, i.e. error codes from the list maintained in exit-codes.[ch]
167 * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
168 files and directories that are left writable for a unit, and which are
169 removed after the unit goes down again. A bit like --ephemeral for
170 systemd-nspawn but for system services. If used together with RootImage= this
171 should reflink the image file itself.
173 Related: add Ephemeral=<path1> <path2> … which would allow marking
174 specific paths only like this.
176 * add CopyFile= or so as unit file setting that may be used to copy files or
177 directory trees from the host to te services RootImage= and RootDirectory=
178 environment. Which we can use for /etc/machine-id and in particular
179 /etc/resolv.conf. Should be smart and do something useful on read-only
180 images, for example fallback to read-only bind mounting the file instead.
182 * nspawn's console TTY should be allocated from within the container, not
183 mounted in from the outside
185 * show invocation ID in systemd-run output
187 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
189 * tree-wide: ensure we always block the signals we hook into with
190 sd_event_add_signal() first
192 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
193 and so on, which would mean we could report errors and such.
195 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
198 * introduce DefaultSlice= or so in system.conf that allows changing where we
199 place our units by default, i.e. change system.slice to something
200 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
201 be moved somewhere else too. Finally machined and logind should get similar
202 options so that it is possible to move user session scopes and machines to a
203 different slice too by default. Usecase: people who want to put resources on
204 the entire system, with the exception of one specific service. See:
205 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
207 * maybe rework get_user_creds() to query the user database if $SHELL is used
208 for root, but only then.
210 * be stricter with fds we receive for the fdstore: close them asynchronously
212 * calenderspec: add support for week numbers and day numbers within a
213 year. This would allow us to define "bi-weekly" triggers safely.
215 * sd-bus: add vtable flag, that may be used to request client creds implicitly
216 and asynchronously before dispatching the operation
218 * make use of ethtool veth peer info in machined, for automatically finding out
219 host-side interface pointing to the container.
221 * add some special mode to LogsDirectory=/StateDirectory=… that allows
222 declaring these directories without necessarily pulling in deps for them, or
223 creating them when starting up. That way, we could declare that
224 systemd-journald writes to /var/log/journal, which could be useful when we
225 doing disk usage calculations and so on.
227 * taint systemd if there are fewer than 65536 users assigned (userns) to the system.
229 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
231 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
232 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
233 as the unit is running or has a job queued.
235 * support projid-based quota in machinectl for containers, and then drop
236 implicit btrfs loopback magic in machined
238 * Add NetworkNamespacePath= to specify a path to a network namespace
240 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
241 introduced) as the RTC epoch, instead of the mtime of NEWS.
243 * add a way to lock down cgroup migration: a boolean, which when set for a unit
244 makes sure the processes in it can never migrate out of it
246 * blog about fd store and restartable services
248 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
250 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
251 magic meaning and is no longer upgraded to something else if set explicitly.
253 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
254 make it lose its identity, i.e. be anonymous. For this we'd have to patch
255 through the whole tree to make all code deal with the case where no machine
258 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
259 suitable for processing with rrdtool. Add bus API to access this data, and
260 possibly implement a CPULoad property based on it.
262 * beef up pam_systemd to take unit file settings such as cgroups properties as
265 * a new "systemd-analyze security" tool outputting a checklist of security
266 features a service does and does not implement
268 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
269 the quota of a the user indicated in User= via unit file settings, like the
270 other resource management concepts. Would mix nicely with DynamicUser=1. Or
271 alternatively, do this with projids, so that we can also cover services
272 running as root. Quota should probably cover all the special dirs such as
273 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
274 is set, plus the whole disk space any image configured with RootImage=.
276 * Introduce "exit" as an EmergencyAction value, and allow to configure a
277 per-unit success/failure exit code to configure. This would be useful for
278 running commands inside of services inside of containers, which could then
279 propagate their failure state all the way up.
281 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
282 disks to see if the UID is already in use.
284 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
285 for all units. It should be both a way to pin units into memory as well as a
286 wait to retrieve their exit data.
288 * expose IO accounting data on the bus, show it in systemd-run --wait and log
289 about it in the resource log message
291 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
292 unit when it is stopped
294 * show whether a service has out-of-date configuration in "systemctl status" by
295 using mtime data of ConfigurationDirectory=.
297 * replace all uses of fgets() + LINE_MAX by read_line()
299 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
300 creates a static, persistent user rather than a dynamic, transient user. We
301 can leverage code from sysusers.d for this.
303 * add some optional flag to ReadWritePaths= and friends, that has the effect
304 that we create the dir in question when the service is started. Example:
306 ReadWritePaths=:/var/lib/foobar
308 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
309 the sd-journal logging socket, and, if the timeout is set to 0, sets
310 O_NONBLOCK on it. That way people can control if and when to block for
313 * hostnamed: populate form factor data from a new hwdb database, so that old
314 yogas can be recognized as "convertible" too, even if they predate the DMI
315 "convertible" form factor
317 * Maybe add a small tool invoked early at boot, that adds in or resizes
318 partitions automatically, to be used when the media used is actually larger
319 than the image written onto it is.
321 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
322 after all. Be strict however, only support the equivalent of nspawn's
323 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
326 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
327 the service cgroup, which is supposed to monitor the service, and when it
328 exits the service is considered failed by its monitor.
330 * track the per-service PAM process properly (i.e. as an additional control
331 process), so that it may be queried on the bus and everything.
333 * add a new "debug" job mode, that is propagated to unit_start() and for
334 services results in two things: we raise SIGSTOP right before invoking
335 execve() and turn off watchdog support. Then, use that to implement
336 "systemd-gdb" for attaching to the start-up of any system service in its
339 * maybe introduce gpt auto discovery for /var/tmp?
341 * maybe add gpt-partition-based user management: each user gets his own
342 LUKS-encrypted GPT partition with a new GPT type. A small nss module
343 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
344 way: the partition index is added as offset to some fixed base uid. User name
345 is stored in GPT partition name. A PAM module authenticates the user via the
346 LUKS partition password. Benefits: strong per-user security, compatibility
347 with stateless/read-only/verity-enabled root. (other idea: do this based on
348 loopback files in /home, without GPT involvement)
350 * gpt-auto logic: introduce support for discovering /var matching an image. For
351 that, use a partition type UUID that is hashed from the OS name (as encoded
352 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
353 field of the root partition. This way can easily support multiple OS
354 installations on the same GPT partition table, without problems with
355 unmatched /var partitions.
357 * gpt-auto logic: related to the above, maybe support a "secondary" root
358 partition, that is mounted to / and is writable, and where the actual root's
359 /usr is mounted into.
361 * 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
363 * drop nss-myhostname in favour of nss-resolve?
365 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
366 then use that for the setting used in user@.service. It should be understood
367 relative to the configured default value.
369 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
371 * enable LockMLOCK to take a percentage value relative to physical memory
373 * Permit masking specific netlink APIs with RestrictAddressFamily=
375 * nspawn: support that /proc, /sys/, /dev are pre-mounted
377 * define gpt header bits to select volatility mode
379 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
381 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
383 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
385 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
387 * ProtectKeyRing= to take keyring calls away
389 * RemoveKeyRing= to remove all keyring entries of the specified user
391 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
392 on PID 1 with the relevant signals, and makes relevant files in /sys and
393 /proc (such as the sysrq stuff) unavailable
395 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
397 * journalctl: make sure -f ends when the container indicated by -M terminates
399 * mount: automatically search for "main" partition of an image has multiple
402 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
405 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
406 find a way to map the User=/Group= of the service to the right name. This way
407 a user/group for a service only has to exist on the host for the right
410 * add bus API for creating unit files in /etc, reusing the code for transient units
412 * add bus API to remove unit files from /etc
414 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
416 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
417 kernel doesn't support linkat() that replaces existing files, currently)
419 * transient units: don't bother with actually setting unit properties, we
420 reload the unit file anyway
422 * journald: sigbus API via a signal-handler safe function that people may call
423 from the SIGBUS handler
425 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
427 * resolved: when routing queries, make sure only look for the *longest* suffix...
429 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
430 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
432 * cache sd_event_now() result from before the first iteration...
434 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
436 * PID1: find a way how we can reload unit file configuration for
437 specific units only, without reloading the whole of systemd
439 * add an explicit parser for LimitRTPRIO= that verifies
440 the specified range and generates sane error messages for incorrect
443 * when we detect that there are waiting jobs but no running jobs, do something
445 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
447 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
449 * there's probably something wrong with having user mounts below /sys,
450 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
451 prefixed with /sys generally special.
452 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
454 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
456 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
458 * add a job mode that will fail if a transaction would mean stopping
459 running units. Use this in timedated to manage the NTP service
461 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
463 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
464 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
466 * The udev blkid built-in should expose a property that reflects
467 whether media was sensed in USB CF/SD card readers. This should then
468 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
469 picked up by systemd unless they contain a medium. This would mirror
470 the behaviour we already have for CD drives.
472 * networkd/udev: implement SR_IOV configuration in .link files:
473 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
475 * hostnamectl: show root image uuid
477 * Find a solution for SMACK capabilities stuff:
478 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
480 * "systemctl preset-all" should probably order the unit files it
481 operates on lexicographically before starting to work, in order to
482 ensure deterministic behaviour if two unit files conflict (like DMs
485 * synchronize console access with BSD locks:
486 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
488 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
489 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
491 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
493 * figure out when we can use the coarse timers
495 * add "systemctl start -v foobar.service" that shows logs of a service
496 while the start command runs. This is non-trivial to do without
497 races though, since we should flush out all journal messages before
498 returning from the "systemctl stop".
500 * 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
502 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
504 * consider showing the unit names during boot up in the status output, not just the unit descriptions
506 * maybe allow timer units with an empty Units= setting, so that they
507 can be used for resuming the system but nothing else.
509 * what to do about udev db binary stability for apps? (raw access is not an option)
511 * man: maybe use the word "inspect" rather than "introspect"?
513 * systemctl: if some operation fails, show log output?
515 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
516 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
518 * exponential backoff in timesyncd when we cannot reach a server
520 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
522 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
524 * systemd.show_status= should probably have a mode where only failed
527 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
528 (throughout the codebase, not only PID1)
532 - service registration
533 - service/domain/types browsing
535 - DNS-SD service registration from socket units
536 - resolved should optionally register additional per-interface LLMNR
537 names, so that for the container case we can establish the same name
538 (maybe "host") for referencing the server, everywhere.
539 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
540 - hook up resolved with machined-based address resolution
542 * refcounting in sd-resolve is borked
544 * Add a new verb "systemctl top"
546 * add new gpt type for btrfs volumes
548 * support empty /etc boots nicely:
549 - nspawn/gpt-generator: introduce new gpt partition type for /usr
551 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
553 * a way for container managers to turn off getty starting via $container_headless= or so...
555 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
557 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
558 they run added to the initial transaction and thus confuse Type=idle.
560 * add bus api to query unit file's X fields.
562 * gpt-auto-generator:
563 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
564 - Make /home automount rather than mount?
566 * add generator that pulls in systemd-network from containers when
567 CAP_NET_ADMIN is set, more than the loopback device is defined, even
568 when it is otherwise off
570 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
572 * implement Distribute= in socket units to allow running multiple
573 service instances processing the listening socket, and open this up
576 * socket units: support creating sockets in different namespace,
577 opening it up for JoinsNamespaceOf=. This would require to fork off
578 a tiny process that joins the namespace and creates/binds the socket
579 and passes this back to PID1 via SCM_RIGHTS. This also could be used
580 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
582 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
583 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
584 should SIGSTOP all unit processes in a loop until all processes of
585 it are fully stopped. This can later be used for app management by
586 desktop UIs such as gnome-shell to freeze apps that are not visible
587 on screen, not unlike how job control works on the shell
590 - implement per-slice CPUFairScheduling=1 switch
591 - handle jointly mounted controllers correctly
592 - introduce high-level settings for RT budget, swappiness
593 - how to reset dynamically changed unit cgroup attributes sanely?
594 - when reloading configuration, apply new cgroup configuration
595 - when recursively showing the cgroup hierarchy, optionally also show
596 the hierarchies of child processes
599 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
601 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
603 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
605 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
607 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
609 * 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
611 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
613 * If we try to find a unit via a dangling symlink, generate a clean
614 error. Currently, we just ignore it and read the unit from the search
617 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
619 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
621 * load .d/*.conf dropins for device units
623 * allow implementation of InaccessibleDirectories=/ plus
624 ReadOnlyDirectories=... for whitelisting files for a service.
628 - GetAllProperties() on a non-existing object does not result in a failure currently
629 - port to sd-resolve for connecting to TCP dbus servers
630 - 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
631 - see if we can drop more message validation on the sending side
632 - add API to clone sd_bus_message objects
633 - longer term: priority inheritance
635 - NameLost/NameAcquired obsolete
638 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
641 - allow multiple signal handlers per signal?
642 - document chaining of signal handler for SIGCHLD and child handlers
643 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
644 - generate a failure of a default event loop is executed out-of-thread
646 * investigate endianness issues of UUID vs. GUID
648 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
649 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
651 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
653 * add a pam module that on password changes updates any LUKS slot where the password matches
655 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
658 - add unit tests for config_parse_device_allow()
660 * seems that when we follow symlinks to units we prefer the symlink
661 destination path over /etc and /usr. We should not do that. Instead
662 /etc should always override /run+/usr and also any symlink
665 * when isolating, try to figure out a way how we implicitly can order
666 all units we stop before the isolating unit...
668 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
670 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
671 that the boot loader should be installed to the ESP. Define a way
672 how an installer can figure out whether a BLS compliant boot loader
675 * think about requeuing jobs when daemon-reload is issued? usecase:
676 the initrd issues a reload after fstab from the host is accessible
677 and we might want to requeue the mounts local-fs acquired through
680 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
682 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
684 * shutdown logging: store to EFI var, and store to USB stick?
686 * merge unit_kill_common() and unit_kill_context()
688 * introduce ExecCondition= in services
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 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
697 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
699 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
702 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
703 - logind: wakelock/opportunistic suspend support
704 - Add pretty name for seats in logind
705 - logind: allow showing logout dialog from system?
706 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
707 - if pam_systemd is invoked by su from a process that is outside of a
708 any session we should probably just become a NOP, since that's
709 usually not a real user session but just some system code that just
711 - logind: make the Suspend()/Hibernate() bus calls wait for the for
712 the job to be completed. before returning, so that clients can wait
713 for "systemctl suspend" to finish to know when the suspending is
715 - logind: when the power button is pressed short, just popup a
716 logout dialog. If it is pressed for 1s, do the usual
717 shutdown. Inspiration are Macs here.
718 - expose "Locked" property on logind sesison objects
719 - maybe allow configuration of the StopTimeout for session scopes
720 - rename session scope so that it includes the UID. THat way
721 the session scope can be arranged freely in slices and we don't have
722 make assumptions about their slice anymore.
723 - follow PropertiesChanged state more closely, to deal with quick logouts and
726 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
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 alraedy after a short tiemout
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
811 - add systemctl switch to dump transaction without executing it
812 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
813 - "systemctl disable" on a static unit prints no message and does
814 nothing. "systemctl enable" does nothing, and gives a bad message
815 about it. Should fix both to print nice actionable messages.
816 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
817 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
818 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
819 - systemctl: "Journal has been rotated since unit was started." message is misleading
820 - systemctl status output should include list of triggering units and their status
823 - "systemctl mask" should find all names by which a unit is accessible
824 (i.e. by scanning for symlinks to it) and link them all to /dev/null
827 - timer units should get the ability to trigger when:
828 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
831 - Modulate timer frequency based on battery state
833 * add libsystemd-password or so to query passwords during boot using the password agent logic
835 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
837 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
839 * make repeated alt-ctrl-del presses printing a dump
841 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
843 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
846 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
847 with seccomp. That should provide us with a useful log buffer that
848 systemd can log to during early boot, and disconnect container logs
849 from the kernel's logs.
850 - as soon as networkd has a bus interface, hook up --network-interface=,
851 --network-bridge= with networkd, to trigger netdev creation should an
853 - a nice way to boot up without machine id set, so that it is set at boot
854 automatically for supporting --ephemeral. Maybe hash the host machine id
855 together with the machine name to generate the machine id for the container
856 - fix logic always print a final newline on output.
857 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
858 - should optionally support receiving WATCHDOG=1 messages from its payload
860 - optionally automatically add FORWARD rules to iptables whenever nspawn is
861 running, remove them when shut down.
862 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
866 - refuse mounting over a mount point
867 - automatically discover .roothash files in dissect, similarly to nspawn
870 - add an API so that libvirt-lxc can inform us about network interfaces being
871 removed or added to an existing machine
872 - "machinectl migrate" or similar to copy a container from or to a
873 difference host, via ssh
874 - introduce systemd-nspawn-ephemeral@.service, and hook it into
875 "machinectl start" with a new --ephemeral switch
876 - "machinectl status" should also show internal logs of the container in
878 - "machinectl history"
880 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
881 shell in it, and marks it read-only after use
884 - generate a nice warning if mkfs.btrfs is missing
887 - cryptsetup-generator: allow specification of passwords in crypttab itself
888 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
890 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
891 https://bugs.freedesktop.org/show_bug.cgi?id=54712
893 * add a dependency on standard-conf.xml and other included files to man pages
895 * MountFlags=shared acts as MountFlags=slave right now.
897 * properly handle loop back mounts via fstab, especially regards to fsck/passno
899 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
904 - add trigger --subsystem-match=usb/usb_device device
905 - reimport udev db after MOVE events for devices without dev_t
907 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
909 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
912 - save coredump in Windows/Mozilla minidump format
913 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
915 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
917 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
919 * be able to specify a forced restart of service A where service B depends on, in case B
920 needs to be auto-respawned?
923 - apply "x" on "D" too (see patch from William Douglas)
925 - instead of ignoring unknown fields, reject them.
926 - creating new directories/subvolumes/fifos/device nodes
927 should not follow symlinks. None of the other adjustment or creation
928 calls follow symlinks.
930 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
932 * verify that the AF_UNIX sockets of a service in the fs still exist
933 when we start a service in order to avoid confusion when a user
934 assumes starting a service is enough to make it accessible
936 * Make it possible to set the keymap independently from the font on
937 the kernel cmdline. Right now setting one resets also the other.
939 * and a dbus call to generate target from current state
941 * write blog stories about:
942 - hwdb: what belongs into it, lsusb
943 - enabling dbus services
944 - how to make changes to sysctl and sysfs attributes
946 - how to pass throw-away units to systemd, or dynamically change properties of existing units
947 - testing with Harald's awesome test kit
949 - how to develop against journal browsing APIs
950 - the journal HTTP iface
951 - non-cgroup resource management
952 - dynamic resource management with cgroups
953 - refreshed, longer missions statement
954 - calendar time events
955 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
956 - how to create your own target
957 - instantiated apache, dovecot and so on
958 - hooking a script into various stages of shutdown/rearly booot
960 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
962 * dot output for --test showing the 'initial transaction'
965 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
966 log both units as UNIT=, so that journalctl -u triggers on both.
967 - generate better errors when people try to set transient properties
968 that are not supported...
969 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
970 - maybe introduce WantsMountsFor=? Usecase:
971 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
972 - recreate systemd's D-Bus private socket file on SIGUSR2
973 - move PAM code into its own binary
974 - when we automatically restart a service, ensure we restart its rdeps, too.
975 - hide PAM options in fragment parser when compile time disabled
976 - Support --test based on current system state
977 - 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().
978 - after deserializing sockets in socket.c we should reapply sockopts and things
979 - drop PID 1 reloading, only do reexecing (difficult: Reload()
980 currently is properly synchronous, Reexec() is weird, because we
981 cannot delay the response properly until we are back, so instead of
982 being properly synchronous we just keep open the fd and close it
983 when done. That means clients do not get a successful method reply,
984 but much rather a disconnect on success.
985 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
986 - when a bus name of a service disappears from the bus make sure to queue further activation requests
989 - allow port=0 in .socket units
990 - maybe introduce ExecRestartPre=
991 - add ReloadSignal= for configuring a reload signal to use
992 - implement Register= switch in .socket units to enable registration
993 in Avahi, RPC and other socket registration services.
994 - allow Type=simple with PIDFile=
995 https://bugzilla.redhat.com/show_bug.cgi?id=723942
996 - allow writing multiple conditions in unit files on one line
997 - load-fragment: when loading a unit file via a chain of symlinks
998 verify that it is not masked via any of the names traversed.
999 - introduce Type=pid-file
1000 - introduce mix of BindTo and Requisite
1001 - add a concept of RemainAfterExit= to scope units
1002 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
1005 - Make sure ID_PATH is always exported and complete for
1006 network devices where possible, so we can safely rely
1008 - check MTUBytes parsing (expecting size_t but we are using unsigned)
1011 - add support for more attribute types
1012 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
1015 - add more keys to [Route] and [Address] sections
1016 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
1017 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
1018 - add reduced [Link] support to .network files
1019 - add Scope= parsing option for [Network]
1020 - properly handle routerless dhcp leases
1021 - work with non-Ethernet devices
1022 - add support for more bond options
1023 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
1024 - the DHCP lease data (such as NTP/DNS) is still made available when
1025 a carrier is lost on a link. It should be removed instantly.
1026 - expose in the API the following bits:
1027 - option 15, domain name and/or option 119, search list
1028 - option 12, host name and/or option 81, fqdn
1029 - option 123, 144, geolocation
1030 - option 252, configure http proxy (PAC/wpad)
1031 - provide a way to define a per-network interface default metric value
1032 for all routes to it. possibly a second default for DHCP routes.
1033 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1034 support Name=foo*|bar*|baz ?
1035 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
1036 - allow DUID/IAID to be customized, see issue #394.
1037 - whenever uplink info changes, make DHCP server send out FORCERENEW
1039 * networkd-wait-online:
1040 - make operstates to wait for configurable?
1043 - figure out how much we can increase Maximum Message Size
1046 - add functions to set previously stored IPv6 addresses on startup and get
1047 them at shutdown; store them in client->ia_na
1048 - write more test cases
1049 - implement reconfigure support, see 5.3., 15.11. and 22.20.
1050 - implement support for temporary adressess (IA_TA)
1051 - implement dhcpv6 authentication
1052 - investigate the usefulness of Confirm messages; i.e. are there any
1053 situations where the link changes without any loss in carrier detection
1055 - some servers don't do rapid commit without a filled in IA_NA, verify
1062 - natively watch for dbus-*.service symlinks (PENDING)
1063 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
1065 * fix alsa mixer restore to not print error when no config is stored
1067 * make cryptsetup lower --iter-time
1069 * patch kernel for xattr support in /dev, /proc/, /sys?
1071 * kernel: add device_type = "fb", "fbcon" to class "graphics"
1073 * /usr/bin/service should actually show the new command line
1075 * 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=
1077 * fedora: F20: go timer units all the way, leave cron.daily for cron
1079 * neither pkexec nor sudo initialize environ[] from the PAM environment?
1081 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
1083 * register catalog database signature as file magic
1085 * zsh shell completion:
1086 - <command> <verb> -<TAB> should complete options, but currently does not
1087 - systemctl add-wants,add-requires
1092 * look for close() vs. close_nointr() vs. close_nointr_nofail()
1094 * check for strerror(r) instead of strerror(-r)
1098 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
1100 * use secure_getenv() instead of getenv() where appropriate
1102 * link up selected blog stories from man pages and unit files Documentation= fields
