3 * Should systemctl status \* work on all unit types, not just .service?
5 * Dangling symlinks of .automount unit files in .wants/ directories, set up
6 automount points even when the original .automount file did not exist
7 anymore. Only the .mount unit was still around.
9 * ExecStart with unicode characters fails in strv_split_extract:
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
17 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
19 * wiki: update journal format documentation for lz4 additions
23 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
27 * nspawn's console TTY should be allocated from within the container, not
28 mounted in from the outside
30 * show invocation ID in elogind-run output
32 * bypass SIGTERM state in unit files if KillSignal is SIGKILL
34 * tree-wide: ensure we always block the signals we hook into with
35 sd_event_add_signal() first
37 * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
38 and so on, which would mean we could report errors and such.
40 * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
43 * introduce DefaultSlice= or so in system.conf that allows changing where we
44 place our units by default, i.e. change system.slice to something
45 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
46 be moved somewhere else too. Finally machined and logind should get similar
47 options so that it is possible to move user session scopes and machines to a
48 different slice too by default. Usecase: people who want to put resources on
49 the entire system, with the exception of one specific service. See:
50 https://lists.freedesktop.org/archives/elogind-devel/2018-February/040369.html
52 * maybe rework get_user_creds() to query the user database if $SHELL is used
53 for root, but only then.
55 * be stricter with fds we receive for the fdstore: close them asynchronously
57 * calenderspec: add support for week numbers and day numbers within a
58 year. This would allow us to define "bi-weekly" triggers safely.
60 * add bpf-based implementation of devices cgroup controller logic for compat
61 with cgroupsv2 as supported by newest kernel
63 * introduce sd_id128_get_boot_app_specific() which is like
64 sd_id128_get_machine_app_specific(). After all on long-running systems both
65 IDs have similar properties.
67 * sd-bus: add vtable flag, that may be used to request client creds implicitly
68 and asynchronously before dispatching the operation
70 * make use of ethtool veth peer info in machined, for automatically finding out
71 host-side interface pointing to the container.
73 * add some special mode to LogsDirectory=/StateDirectory=… that allows
74 declaring these directories without necessarily pulling in deps for them, or
75 creating them when starting up. That way, we could declare that
76 systemd-journald writes to /var/log/journal, which could be useful when we
77 doing disk usage calculations and so on.
79 * taint elogind if there are fewer than 65536 users assigned (userns) to the system.
81 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
83 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
84 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
85 as the unit is running or has a job queued.
87 * support projid-based quota in machinectl for containers, and then drop
88 implicit btrfs loopback magic in machined
90 * Add NetworkNamespacePath= to specify a path to a network namespace
92 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
93 introduced) as the RTC epoch, instead of the mtime of NEWS.
95 * add a way to lock down cgroup migration: a boolean, which when set for a unit
96 makes sure the processes in it can never migrate out of it
98 * blog about fd store and restartable services
100 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
102 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
103 magic meaning and is no longer upgraded to something else if set explicitly.
105 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
106 make it lose its identity, i.e. be anonymous. For this we'd have to patch
107 through the whole tree to make all code deal with the case where no machine
110 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
111 suitable for processing with rrdtool. Add bus API to access this data, and
112 possibly implement a CPULoad property based on it.
114 * beef up pam_systemd to take unit file settings such as cgroups properties as
117 * a new "systemd-analyze security" tool outputting a checklist of security
118 features a service does and does not implement
120 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
121 the quota of a the user indicated in User= via unit file settings, like the
122 other resource management concepts. Would mix nicely with DynamicUser=1. Or
123 alternatively, do this with projids, so that we can also cover services
124 running as root. Quota should probably cover all the special dirs such as
125 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
126 is set, plus the whole disk space any image configured with RootImage=.
128 * Introduce "exit" as an EmergencyAction value, and allow to configure a
129 per-unit success/failure exit code to configure. This would be useful for
130 running commands inside of services inside of containers, which could then
131 propagate their failure state all the way up.
133 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
134 disks to see if the UID is already in use.
136 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
137 for all units. It should be both a way to pin units into memory as well as a
138 wait to retrieve their exit data.
140 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
141 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
142 automatically. For example, there could be $RUNTIME_DIRECTORY,
143 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
144 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
145 can adapt to varying directories for these purposes. Special care has to be
146 taken if multiple dirs are configured. Maybe avoid setting the env vars in
149 * expose IO accounting data on the bus, show it in systemd-run --wait and log
150 about it in the resource log message
152 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
153 unit when it is stopped
155 * show whether a service has out-of-date configuration in "systemctl status" by
156 using mtime data of ConfigurationDirectory=.
158 * replace all uses of fgets() + LINE_MAX by read_line()
160 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
161 creates a static, persistent user rather than a dynamic, transient user. We
162 can leverage code from sysusers.d for this.
164 * add some optional flag to ReadWritePaths= and friends, that has the effect
165 that we create the dir in question when the service is started. Example:
167 ReadWritePaths=:/var/lib/foobar
169 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
170 the sd-journal logging socket, and, if the timeout is set to 0, sets
171 O_NONBLOCK on it. That way people can control if and when to block for
174 * hostnamed: populate form factor data from a new hwdb database, so that old
175 yogas can be recognized as "convertible" too, even if they predate the DMI
176 "convertible" form factor
178 * Maybe add a small tool invoked early at boot, that adds in or resizes
179 partitions automatically, to be used when the media used is actually larger
180 than the image written onto it is.
182 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
183 after all. Be strict however, only support the equivalent of nspawn's
184 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
187 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
188 the service cgroup, which is supposed to monitor the service, and when it
189 exits the service is considered failed by its monitor.
191 * track the per-service PAM process properly (i.e. as an additional control
192 process), so that it may be queried on the bus and everything.
194 * add a new "debug" job mode, that is propagated to unit_start() and for
195 services results in two things: we raise SIGSTOP right before invoking
196 execve() and turn off watchdog support. Then, use that to implement
197 "systemd-gdb" for attaching to the start-up of any system service in its
200 * maybe introduce gpt auto discovery for /var/tmp?
202 * maybe add gpt-partition-based user management: each user gets his own
203 LUKS-encrypted GPT partition with a new GPT type. A small nss module
204 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
205 way: the partition index is added as offset to some fixed base uid. User name
206 is stored in GPT partition name. A PAM module authenticates the user via the
207 LUKS partition password. Benefits: strong per-user security, compatibility
208 with stateless/read-only/verity-enabled root. (other idea: do this based on
209 loopback files in /home, without GPT involvement)
211 * gpt-auto logic: introduce support for discovering /var matching an image. For
212 that, use a partition type UUID that is hashed from the OS name (as encoded
213 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
214 field of the root partition. This way can easily support multiple OS
215 installations on the same GPT partition table, without problems with
216 unmatched /var partitions.
218 * gpt-auto logic: related to the above, maybe support a "secondary" root
219 partition, that is mounted to / and is writable, and where the actual root's
220 /usr is mounted into.
222 * 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
224 * drop nss-myhostname in favour of nss-resolve?
226 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
227 then use that for the setting used in user@.service. It should be understood
228 relative to the configured default value.
230 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
232 * enable LockMLOCK to take a percentage value relative to physical memory
234 * Permit masking specific netlink APIs with RestrictAddressFamily=
236 * nspawn: support that /proc, /sys/, /dev are pre-mounted
238 * define gpt header bits to select volatility mode
240 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
242 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
244 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
246 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
248 * ProtectKeyRing= to take keyring calls away
250 * RemoveKeyRing= to remove all keyring entries of the specified user
252 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
253 on PID 1 with the relevant signals, and makes relevant files in /sys and
254 /proc (such as the sysrq stuff) unavailable
256 * DeviceAllow= should also generate seccomp filters for mknod()
258 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
260 * journalctl: make sure -f ends when the container indicated by -M terminates
262 * mount: automatically search for "main" partition of an image has multiple
265 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
268 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
269 find a way to map the User=/Group= of the service to the right name. This way
270 a user/group for a service only has to exist on the host for the right
273 * add bus API for creating unit files in /etc, reusing the code for transient units
275 * add bus API to remove unit files from /etc
277 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
279 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
280 kernel doesn't support linkat() that replaces existing files, currently)
282 * check if DeviceAllow= should split first, resolve specifiers later
284 * transient units: don't bother with actually setting unit properties, we
285 reload the unit file anyway
287 * journald: sigbus API via a signal-handler safe function that people may call
288 from the SIGBUS handler
290 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
292 * resolved: when routing queries, make sure only look for the *longest* suffix...
294 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
295 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
297 * cache sd_event_now() result from before the first iteration...
299 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
301 * PID1: find a way how we can reload unit file configuration for
302 specific units only, without reloading the whole of systemd
304 * add an explicit parser for LimitRTPRIO= that verifies
305 the specified range and generates sane error messages for incorrect
308 * when we detect that there are waiting jobs but no running jobs, do something
310 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
312 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
314 * there's probably something wrong with having user mounts below /sys,
315 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
316 prefixed with /sys generally special.
317 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
319 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
321 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
323 * add a job mode that will fail if a transaction would mean stopping
324 running units. Use this in timedated to manage the NTP service
326 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
328 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
329 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
331 * The udev blkid built-in should expose a property that reflects
332 whether media was sensed in USB CF/SD card readers. This should then
333 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
334 picked up by systemd unless they contain a medium. This would mirror
335 the behaviour we already have for CD drives.
337 * networkd/udev: implement SR_IOV configuration in .link files:
338 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
340 * hostnamectl: show root image uuid
342 * sysfs set api in libudev is not const
344 * Find a solution for SMACK capabilities stuff:
345 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
347 * "systemctl preset-all" should probably order the unit files it
348 operates on lexicographically before starting to work, in order to
349 ensure deterministic behaviour if two unit files conflict (like DMs
352 * synchronize console access with BSD locks:
353 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
355 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
356 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
358 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
360 * figure out when we can use the coarse timers
362 * add "systemctl start -v foobar.service" that shows logs of a service
363 while the start command runs. This is non-trivial to do without
364 races though, since we should flush out all journal messages before
365 returning from the "systemctl stop".
367 * 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
369 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
371 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
373 * consider showing the unit names during boot up in the status output, not just the unit descriptions
375 * maybe allow timer units with an empty Units= setting, so that they
376 can be used for resuming the system but nothing else.
378 * what to do about udev db binary stability for apps? (raw access is not an option)
380 * man: maybe use the word "inspect" rather than "introspect"?
382 * systemctl: if some operation fails, show log output?
384 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
385 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
387 * exponential backoff in timesyncd when we cannot reach a server
389 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
391 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
393 * systemd.show_status= should probably have a mode where only failed
396 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
397 (throughout the codebase, not only PID1)
401 - service registration
402 - service/domain/types browsing
404 - DNS-SD service registration from socket units
405 - resolved should optionally register additional per-interface LLMNR
406 names, so that for the container case we can establish the same name
407 (maybe "host") for referencing the server, everywhere.
408 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
409 - hook up resolved with machined-based address resolution
411 * refcounting in sd-resolve is borked
413 * Add a new verb "systemctl top"
415 * add new gpt type for btrfs volumes
417 * support empty /etc boots nicely:
418 - nspawn/gpt-generator: introduce new gpt partition type for /usr
420 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
422 * a way for container managers to turn off getty starting via $container_headless= or so...
424 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
426 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
427 they run added to the initial transaction and thus confuse Type=idle.
429 * add bus api to query unit file's X fields.
431 * gpt-auto-generator:
432 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
433 - Make /home automount rather than mount?
435 * add generator that pulls in systemd-network from containers when
436 CAP_NET_ADMIN is set, more than the loopback device is defined, even
437 when it is otherwise off
439 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
441 * implement Distribute= in socket units to allow running multiple
442 service instances processing the listening socket, and open this up
445 * socket units: support creating sockets in different namespace,
446 opening it up for JoinsNamespaceOf=. This would require to fork off
447 a tiny process that joins the namespace and creates/binds the socket
448 and passes this back to PID1 via SCM_RIGHTS. This also could be used
449 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
451 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
452 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
453 should SIGSTOP all unit processes in a loop until all processes of
454 it are fully stopped. This can later be used for app management by
455 desktop UIs such as gnome-shell to freeze apps that are not visible
456 on screen, not unlike how job control works on the shell
459 - implement per-slice CPUFairScheduling=1 switch
460 - handle jointly mounted controllers correctly
461 - introduce high-level settings for RT budget, swappiness
462 - how to reset dynamically changed unit cgroup attributes sanely?
463 - when reloading configuration, apply new cgroup configuration
464 - when recursively showing the cgroup hierarchy, optionally also show
465 the hierarchies of child processes
468 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
469 - ensure scope units may be started only a single time
471 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
473 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
475 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
477 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
479 * 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
481 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
483 * If we try to find a unit via a dangling symlink, generate a clean
484 error. Currently, we just ignore it and read the unit from the search
487 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
489 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
491 * load .d/*.conf dropins for device units
493 * allow implementation of InaccessibleDirectories=/ plus
494 ReadOnlyDirectories=... for whitelisting files for a service.
498 - GetAllProperties() on a non-existing object does not result in a failure currently
499 - port to sd-resolve for connecting to TCP dbus servers
500 - 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
501 - see if we can drop more message validation on the sending side
502 - add API to clone sd_bus_message objects
503 - longer term: priority inheritance
505 - NameLost/NameAcquired obsolete
508 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
511 - allow multiple signal handlers per signal?
512 - document chaining of signal handler for SIGCHLD and child handlers
513 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
514 - generate a failure of a default event loop is executed out-of-thread
515 - maybe add support for inotify events
517 * investigate endianness issues of UUID vs. GUID
519 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
520 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
522 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
524 * add a pam module that on password changes updates any LUKS slot where the password matches
526 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
529 - add unit tests for config_parse_device_allow()
531 * seems that when we follow symlinks to units we prefer the symlink
532 destination path over /etc and /usr. We should not do that. Instead
533 /etc should always override /run+/usr and also any symlink
536 * when isolating, try to figure out a way how we implicitly can order
537 all units we stop before the isolating unit...
539 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
541 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
542 that the boot loader should be installed to the ESP. Define a way
543 how an installer can figure out whether a BLS compliant boot loader
546 * think about requeuing jobs when daemon-reload is issued? usecase:
547 the initrd issues a reload after fstab from the host is accessible
548 and we might want to requeue the mounts local-fs acquired through
551 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
553 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
555 * shutdown logging: store to EFI var, and store to USB stick?
557 * merge unit_kill_common() and unit_kill_context()
559 * introduce ExecCondition= in services
562 - honor language efi variables for default language selection (if there are any?)
563 - honor timezone efi variables for default timezone selection (if there are any?)
564 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
566 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
568 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
570 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
573 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
574 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
575 - logind: wakelock/opportunistic suspend support
576 - Add pretty name for seats in logind
577 - logind: allow showing logout dialog from system?
578 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
579 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
580 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
581 - if pam_systemd is invoked by su from a process that is outside of a
582 any session we should probably just become a NOP, since that's
583 usually not a real user session but just some system code that just
585 - logind: make the Suspend()/Hibernate() bus calls wait for the for
586 the job to be completed. before returning, so that clients can wait
587 for "systemctl suspend" to finish to know when the suspending is
589 - logind: when the power button is pressed short, just popup a
590 logout dialog. If it is pressed for 1s, do the usual
591 shutdown. Inspiration are Macs here.
592 - expose "Locked" property on logind sesison objects
593 - given that logind now lets PID 1 do all nasty work, we can
594 probably reduce the capability set it retains substantially.
595 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
596 - expose orientation sensors and tablet mode through logind
597 - maybe allow configuration of the StopTimeout for session scopes
598 - rename session scope so that it includes the UID. THat way
599 the session scope can be arranged freely in slices and we don't have
600 make assumptions about their slice anymore.
601 - follow PropertiesChanged state more closely, to deal with quick logouts and
604 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
607 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
608 - import and delete pstore filesystem content at startup
609 - journald: also get thread ID from client, plus thread name
610 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
611 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
612 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
613 - declare the local journal protocol stable in the wiki interface chart
614 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
615 - journald: when dropping msgs due to ratelimit make sure to write
616 "dropped %u messages" not only when we are about to print the next
617 message that works, but alraedy after a short tiemout
618 - check if we can make journalctl by default use --follow mode inside of less if called without args?
619 - maybe add API to send pairs of iovecs via sd_journal_send
620 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
621 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
622 and !FOOBAR for events without FOOBAR.
623 - journal: store timestamp of journal_file_set_offline() int he header,
624 so it is possible to display when the file was last synced.
625 - 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.
626 - journal: find a way to allow dropping history early, based on priority, other rules
627 - journal: When used on NFS, check payload hashes
628 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
629 - refuse taking lower-case variable names in sd_journal_send() and friends.
630 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
631 - journal: deal nicely with byte-by-byte copied files, especially regards header
632 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
633 - Replace utmp, wtmp, btmp, and lastlog completely with journal
634 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
635 - when a kernel driver logs in a tight loop, we should ratelimit that too.
636 - journald: optionally, log debug messages to /run but everything else to /var
637 - journald: when we drop syslog messages because the syslog socket is
638 full, make sure to write how many messages are lost as first thing
639 to syslog when it works again.
640 - change systemd-journal-flush into a service that stays around during
641 boot, and causes the journal to be moved back to /run on shutdown,
642 so that we do not keep /var busy. This needs to happen synchronously,
643 hence doing this via signals is not going to work.
644 - optionally support running journald from the command line for testing purposes in external projects
645 - journald: allow per-priority and per-service retention times when rotating/vacuuming
646 - journald: make use of uid-range.h to managed uid ranges to split
648 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
649 - improve journalctl performance by loading journal files
650 lazily. Encode just enough information in the file name, so that we
651 do not have to open it to know that it is not interesting for us, for
652 the most common operations.
653 - journal-or-kmsg is currently broken? See reverted
654 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
655 - man: document that corrupted journal files is nothing to act on
656 - rework journald sigbus stuff to use mutex
657 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
658 services that run under their own user ids, and use User= (but only
659 in a world where userns is ubiquitous since otherwise we cannot
660 invoke those daemons on the host AND in a container anymore). Also,
661 if LimitNPROC= is used without User= we should warn and refuse
663 - journalctl --verify: don't show files that are currently being
664 written to as FAIL, but instead show that their are being written to.
665 - add journalctl -H that talks via ssh to a remote peer and passes through
667 - add a version of --merge which also merges /var/log/journal/remote
668 - journalctl: -m should access container journals directly by enumerating
669 them via machined, and also watch containers coming and going.
670 Benefit: nspawn --ephemeral would start working nicely with the journal.
671 - assign MESSAGE_ID to log messages about failed services
673 * add a test if all entries in the catalog are properly formatted.
674 (Adding dashes in a catalog entry currently results in the catalog entry
675 being silently skipped. journalctl --update-catalog must warn about this,
676 and we should also have a unit test to check that all our message are OK.)
679 - document that deps in [Unit] sections ignore Alias= fields in
680 [Install] units of other units, unless those units are disabled
681 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
682 - document that service reload may be implemented as service reexec
683 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
684 - document systemd-journal-flush.service properly
685 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
686 - man: document the very specific env the shutdown drop-in tools live in
687 - man: add more examples to man pages
688 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
691 - add systemctl switch to dump transaction without executing it
692 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
693 - "systemctl disable" on a static unit prints no message and does
694 nothing. "systemctl enable" does nothing, and gives a bad message
695 about it. Should fix both to print nice actionable messages.
696 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
697 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
698 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
699 - systemctl: "Journal has been rotated since unit was started." message is misleading
700 - systemctl status output should include list of triggering units and their status
703 - "systemctl mask" should find all names by which a unit is accessible
704 (i.e. by scanning for symlinks to it) and link them all to /dev/null
707 - timer units should get the ability to trigger when:
708 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
710 - Modulate timer frequency based on battery state
712 * add libsystemd-password or so to query passwords during boot using the password agent logic
714 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
716 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
718 * make repeated alt-ctrl-del presses printing a dump
720 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
722 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
725 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
726 with seccomp. That should provide us with a useful log buffer that
727 systemd can log to during early boot, and disconnect container logs
728 from the kernel's logs.
729 - as soon as networkd has a bus interface, hook up --network-interface=,
730 --network-bridge= with networkd, to trigger netdev creation should an
732 - a nice way to boot up without machine id set, so that it is set at boot
733 automatically for supporting --ephemeral. Maybe hash the host machine id
734 together with the machine name to generate the machine id for the container
735 - fix logic always print a final newline on output.
736 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
737 - should optionally support receiving WATCHDOG=1 messages from its payload
739 - optionally automatically add FORWARD rules to iptables whenever nspawn is
740 running, remove them when shut down.
741 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
745 - refuse mounting over a mount point
746 - automatically discover .roothash files in dissect, similarly to nspawn
749 - add an API so that libvirt-lxc can inform us about network interfaces being
750 removed or added to an existing machine
751 - "machinectl migrate" or similar to copy a container from or to a
752 difference host, via ssh
753 - introduce systemd-nspawn-ephemeral@.service, and hook it into
754 "machinectl start" with a new --ephemeral switch
755 - "machinectl status" should also show internal logs of the container in
757 - "machinectl list-images" should show os-release data, as well as
758 machine-info data (including deployment level)
759 - "machinectl history"
761 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
762 shell in it, and marks it read-only after use
765 - generate a nice warning if mkfs.btrfs is missing
768 - cryptsetup-generator: allow specification of passwords in crypttab itself
769 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
771 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
772 https://bugs.freedesktop.org/show_bug.cgi?id=54712
774 * add a dependency on standard-conf.xml and other included files to man pages
776 * MountFlags=shared acts as MountFlags=slave right now.
778 * properly handle loop back mounts via fstab, especially regards to fsck/passno
780 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
785 - add trigger --subsystem-match=usb/usb_device device
786 - reimport udev db after MOVE events for devices without dev_t
788 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
790 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
793 - save coredump in Windows/Mozilla minidump format
794 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
796 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
798 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
800 * be able to specify a forced restart of service A where service B depends on, in case B
801 needs to be auto-respawned?
804 - apply "x" on "D" too (see patch from William Douglas)
806 - instead of ignoring unknown fields, reject them.
807 - creating new directories/subvolumes/fifos/device nodes
808 should not follow symlinks. None of the other adjustment or creation
809 calls follow symlinks.
811 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
813 * verify that the AF_UNIX sockets of a service in the fs still exist
814 when we start a service in order to avoid confusion when a user
815 assumes starting a service is enough to make it accessible
817 * Make it possible to set the keymap independently from the font on
818 the kernel cmdline. Right now setting one resets also the other.
820 * and a dbus call to generate target from current state
822 * write blog stories about:
823 - hwdb: what belongs into it, lsusb
824 - enabling dbus services
825 - how to make changes to sysctl and sysfs attributes
827 - how to pass throw-away units to systemd, or dynamically change properties of existing units
828 - testing with Harald's awesome test kit
830 - how to develop against journal browsing APIs
831 - the journal HTTP iface
832 - non-cgroup resource management
833 - dynamic resource management with cgroups
834 - refreshed, longer missions statement
835 - calendar time events
836 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
837 - how to create your own target
838 - instantiated apache, dovecot and so on
839 - hooking a script into various stages of shutdown/rearly booot
841 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
843 * dot output for --test showing the 'initial transaction'
846 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
847 log both units as UNIT=, so that journalctl -u triggers on both.
848 - generate better errors when people try to set transient properties
849 that are not supported...
850 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
851 - maybe introduce WantsMountsFor=? Usecase:
852 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
853 - recreate systemd's D-Bus private socket file on SIGUSR2
854 - move PAM code into its own binary
855 - when we automatically restart a service, ensure we restart its rdeps, too.
856 - hide PAM options in fragment parser when compile time disabled
857 - Support --test based on current system state
858 - 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().
859 - after deserializing sockets in socket.c we should reapply sockopts and things
860 - drop PID 1 reloading, only do reexecing (difficult: Reload()
861 currently is properly synchronous, Reexec() is weird, because we
862 cannot delay the response properly until we are back, so instead of
863 being properly synchronous we just keep open the fd and close it
864 when done. That means clients do not get a successful method reply,
865 but much rather a disconnect on success.
866 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
867 - when a bus name of a service disappears from the bus make sure to queue further activation requests
870 - allow port=0 in .socket units
871 - maybe introduce ExecRestartPre=
872 - add ReloadSignal= for configuring a reload signal to use
873 - implement Register= switch in .socket units to enable registration
874 in Avahi, RPC and other socket registration services.
875 - allow Type=simple with PIDFile=
876 https://bugzilla.redhat.com/show_bug.cgi?id=723942
877 - allow writing multiple conditions in unit files on one line
878 - load-fragment: when loading a unit file via a chain of symlinks
879 verify that it is not masked via any of the names traversed.
880 - introduce Type=pid-file
881 - introduce mix of BindTo and Requisite
882 - add a concept of RemainAfterExit= to scope units
883 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
886 - Make sure ID_PATH is always exported and complete for
887 network devices where possible, so we can safely rely
889 - check MTUBytes parsing (expecting size_t but we are using unsigned)
892 - add support for more attribute types
893 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
896 - add more keys to [Route] and [Address] sections
897 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
898 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
899 - add reduced [Link] support to .network files
900 - add Scope= parsing option for [Network]
901 - properly handle routerless dhcp leases
902 - work with non-Ethernet devices
903 - add support for more bond options
904 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
905 - the DHCP lease data (such as NTP/DNS) is still made available when
906 a carrier is lost on a link. It should be removed instantly.
907 - expose in the API the following bits:
908 - option 15, domain name and/or option 119, search list
909 - option 12, host name and/or option 81, fqdn
910 - option 123, 144, geolocation
911 - option 252, configure http proxy (PAC/wpad)
912 - provide a way to define a per-network interface default metric value
913 for all routes to it. possibly a second default for DHCP routes.
914 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
915 support Name=foo*|bar*|baz ?
916 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
917 - allow DUID/IAID to be customized, see issue #394.
918 - whenever uplink info changes, make DHCP server send out FORCERENEW
920 * networkd-wait-online:
921 - make operstates to wait for configurable?
924 - figure out how much we can increase Maximum Message Size
927 - add functions to set previously stored IPv6 addresses on startup and get
928 them at shutdown; store them in client->ia_na
929 - write more test cases
930 - implement reconfigure support, see 5.3., 15.11. and 22.20.
931 - implement support for temporary adressess (IA_TA)
932 - implement dhcpv6 authentication
933 - investigate the usefulness of Confirm messages; i.e. are there any
934 situations where the link changes without any loss in carrier detection
936 - some servers don't do rapid commit without a filled in IA_NA, verify
943 - natively watch for dbus-*.service symlinks (PENDING)
944 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
946 * fix alsa mixer restore to not print error when no config is stored
948 * make cryptsetup lower --iter-time
950 * patch kernel for xattr support in /dev, /proc/, /sys?
952 * kernel: add device_type = "fb", "fbcon" to class "graphics"
954 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
956 * /usr/bin/service should actually show the new command line
958 * 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=
960 * fedora: F20: go timer units all the way, leave cron.daily for cron
962 * neither pkexec nor sudo initialize environ[] from the PAM environment?
964 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
966 * register catalog database signature as file magic
968 * zsh shell completion:
969 - <command> <verb> -<TAB> should complete options, but currently does not
970 - systemctl add-wants,add-requires
975 * look for close() vs. close_nointr() vs. close_nointr_nofail()
977 * check for strerror(r) instead of strerror(-r)
981 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
983 * use secure_getenv() instead of getenv() where appropriate
985 * link up selected blog stories from man pages and unit files Documentation= fields
