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 * export UID ranges nspawns's --private-user and DynamicUser= uses in
28 the systemd.pc pkg-config file, the same way we already expose the system
31 * Whenever we check a UID against the system UID range, also check for the
34 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
35 the quota of a the user indicated in User= via unit file settings, like the
36 other resource management concepts. Would mix nicely with DynamicUser=1
38 * add dissect_image_warn() as a wrapper around dissect_image() that prints
39 friendly log messages for the returned errors, so that we don't have to
40 duplicate that in nspawn, systemd-dissect and PID 1.
42 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
43 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
44 automatically. For example, there could be $RUNTIME_DIRECTORY,
45 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
46 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
47 can adapt to varying directories for these purposes. Special care has to be
48 taken if multiple dirs are configured. Maybe avoid setting the env vars in
51 * expose IO accounting data on the bus, show it in systemd-run --wait and log
52 about it in the resource log message
54 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
55 unit when it is stopped
57 * show whether a service has out-of-date configuration in "systemctl status" by
58 using mtime data of ConfigurationDirectory=.
60 * replace all uses of fgets() + LINE_MAX by read_line()
62 * set IPAddressDeny=any on all services that shouldn't do networking (possibly
63 combined with IPAddressAllow=localhost).
65 * dissect: when we discover squashfs, don't claim we had a "writable" partition
68 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
69 creates a static, persistent user rather than a dynamic, transient user. We
70 can leverage code from sysusers.d for this.
72 * add some optional flag to ReadWritePaths= and friends, that has the effect
73 that we create the dir in question when the service is started. Example:
75 ReadWritePaths=:/var/lib/foobar
77 * sort generated hwdb files alphabetically when we import them, so that git
78 diffs remain minimal (in particular: the OUI databases we import are not
79 sorted, and not stable)
81 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
82 the sd-journal logging socket, and, if the timeout is set to 0, sets
83 O_NONBLOCK on it. That way people can control if and when to block for
86 * tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
87 PIDs not managed by the service manager)
89 * hostnamed: populate form factor data from a new hwdb database, so that old
90 yogas can be recognized as "convertible" too, even if they predate the DMI
91 "convertible" form factor
93 * Maybe add a small tool invoked early at boot, that adds in or resizes
94 partitions automatically, to be used when the media used is actually larger
95 than the image written onto it is.
97 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
98 after all. Be strict however, only support the equivalent of nspawn's
99 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
102 * change the dependency Set* objects in Unit structures to become Hashmap*, and
103 then store a bit mask who created a specific dependency: the source unit via
104 fragment configuration, the destination unit via fragment configuration, or
105 the source unit via udev rules (in case of .device units), or any combination
106 thereof. This information can then be used to flush out old udev-created
107 dependencies when the udev properties change, and eventually to implement a
108 "systemctl refresh" operation for reloading the configuration of individual
109 units without reloading the whole set.
111 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
112 the service cgroup, which is supposed to monitor the service, and when it
113 exits the service is considered failed by its monitor.
115 * track the per-service PAM process properly (i.e. as an additional control
116 process), so that it may be queried on the bus and everything.
118 * add a new "debug" job mode, that is propagated to unit_start() and for
119 services results in two things: we raise SIGSTOP right before invoking
120 execve() and turn off watchdog support. Then, use that to implement
121 "systemd-gdb" for attaching to the start-up of any system service in its
124 * replace all canonicalize_file_name() invocations by chase_symlinks(), in
125 particulr those where a rootdir is relevant.
127 * maybe introduce gpt auto discovery for /var/tmp?
129 * maybe add gpt-partition-based user management: each user gets his own
130 LUKS-encrypted GPT partition with a new GPT type. A small nss module
131 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
132 way: the partition index is added as offset to some fixed base uid. User name
133 is stored in GPT partition name. A PAM module authenticates the user via the
134 LUKS partition password. Benefits: strong per-user security, compatibility
135 with stateless/read-only/verity-enabled root. (other idea: do this based on
136 loopback files in /home, without GPT involvement)
138 * gpt-auto logic: introduce support for discovering /var matching an image. For
139 that, use a partition type UUID that is hashed from the OS name (as encoded
140 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
141 field of the root partition. This way can easily support multiple OS
142 installations on the same GPT partition table, without problems with
143 unmatched /var partitions.
145 * gpt-auto logic: related to the above, maybe support a "secondary" root
146 partition, that is mounted to / and is writable, and where the actual root's
147 /usr is mounted into.
149 * machined: add apis to query /etc/machine-info data of a container
151 * .mount and .swap units: add Format=yes|no option that formats the partition before mounting/enabling it, implicitly
153 * 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
155 * drop nss-myhostname in favour of nss-resolve?
157 * drop internal dlopen() based nss-dns fallback in nss-resolve, and rely on the
158 external nsswitch.conf based one
160 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
161 then use that for the setting used in user@.service. It should be understood
162 relative to the configured default value.
164 * on cgroupsv2 add DelegateControllers=, to pick the precise cgroup controllers to delegate
166 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
168 * enable LockMLOCK to take a percentage value relative to physical memory
170 * Permit masking specific netlink APIs with RestrictAddressFamily=
172 * nspawn: start UID allocation loop from hash of container name
174 * nspawn: support that /proc, /sys/, /dev are pre-mounted
176 * define gpt header bits to select volatility mode
178 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
180 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
182 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
184 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
186 * ProtectKeyRing= to take keyring calls away
188 * RemoveKeyRing= to remove all keyring entries of the specified user
190 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
191 on PID 1 with the relevant signals, and makes relevant files in /sys and
192 /proc (such as the sysrq stuff) unavailable
194 * DeviceAllow= should also generate seccomp filters for mknod()
196 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
198 * journalctl: make sure -f ends when the container indicated by -M terminates
200 * mount: automatically search for "main" partition of an image has multiple
203 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
206 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
207 find a way to map the User=/Group= of the service to the right name. This way
208 a user/group for a service only has to exist on the host for the right
211 * allow attaching additional journald log fields to cgroups
213 * add bus API for creating unit files in /etc, reusing the code for transient units
215 * add bus API to remove unit files from /etc
217 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
219 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
220 kernel doesn't support linkat() that replaces existing files, currently)
222 * check if DeviceAllow= should split first, resolve specifiers later
224 * transient units: don't bother with actually setting unit properties, we
225 reload the unit file anyway
227 * journald: sigbus API via a signal-handler safe function that people may call
228 from the SIGBUS handler
230 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
232 * resolved: when routing queries, make sure only look for the *longest* suffix...
234 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
235 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
237 * cache sd_event_now() result from before the first iteration...
239 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
241 * PID1: find a way how we can reload unit file configuration for
242 specific units only, without reloading the whole of systemd
244 * add an explicit parser for LimitRTPRIO= that verifies
245 the specified range and generates sane error messages for incorrect
248 * do something about "/control" subcgroups in the unified cgroup hierarchy
250 * when we detect that there are waiting jobs but no running jobs, do something
252 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
254 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
256 * there's probably something wrong with having user mounts below /sys,
257 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
258 prefixed with /sys generally special.
259 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
261 * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services
263 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
265 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
267 * mounting and unmounting mount points manually with different source
268 devices will result in collected on all devices used.
269 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
271 * add a job mode that will fail if a transaction would mean stopping
272 running units. Use this in timedated to manage the NTP service
274 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
276 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
277 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
279 * The udev blkid built-in should expose a property that reflects
280 whether media was sensed in USB CF/SD card readers. This should then
281 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
282 picked up by systemd unless they contain a medium. This would mirror
283 the behaviour we already have for CD drives.
285 * networkd/udev: implement SR_IOV configuration in .link files:
286 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
288 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
290 * implement a per-service firewall based on net_cls
292 * Port various tools to make use of verbs.[ch], where applicable: busctl,
293 coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
295 * hostnamectl: show root image uuid
297 * sysfs set api in libudev is not const
299 * Find a solution for SMACK capabilities stuff:
300 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
302 * "systemctl preset-all" should probably order the unit files it
303 operates on lexicographically before starting to work, in order to
304 ensure deterministic behaviour if two unit files conflict (like DMs
307 * synchronize console access with BSD locks:
308 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
310 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
311 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
313 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
315 * figure out when we can use the coarse timers
317 * add "systemctl start -v foobar.service" that shows logs of a service
318 while the start command runs. This is non-trivial to do without
319 races though, since we should flush out all journal messages before
320 returning from the "systemctl stop".
322 * 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
324 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
326 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
328 * consider showing the unit names during boot up in the status output, not just the unit descriptions
330 * maybe allow timer units with an empty Units= setting, so that they
331 can be used for resuming the system but nothing else.
333 * what to do about udev db binary stability for apps? (raw access is not an option)
335 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
337 * man: maybe use the word "inspect" rather than "introspect"?
339 * systemctl: if some operation fails, show log output?
341 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
342 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
344 * exponential backoff in timesyncd when we cannot reach a server
346 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
348 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
350 * systemd.show_status= should probably have a mode where only failed
353 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
354 (throughout the codebase, not only PID1)
358 - service registration
359 - service/domain/types browsing
361 - DNS-SD service registration from socket units
362 - resolved should optionally register additional per-interface LLMNR
363 names, so that for the container case we can establish the same name
364 (maybe "host") for referencing the server, everywhere.
365 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
366 - hook up resolved with machined-based address resolution
368 * refcounting in sd-resolve is borked
370 * Add a new verb "systemctl top"
372 * add new gpt type for btrfs volumes
374 * support empty /etc boots nicely:
375 - nspawn/gpt-generator: introduce new gpt partition type for /usr
377 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
379 * a way for container managers to turn off getty starting via $container_headless= or so...
381 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
383 * mount_cgroup_controllers(): symlinks need to get the label applied
385 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
386 they run added to the initial transaction and thus confuse Type=idle.
388 * add bus api to query unit file's X fields.
390 * gpt-auto-generator:
391 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
392 - Make /home automount rather than mount?
394 * add generator that pulls in systemd-network from containers when
395 CAP_NET_ADMIN is set, more than the loopback device is defined, even
396 when it is otherwise off
398 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
400 * implement Distribute= in socket units to allow running multiple
401 service instances processing the listening socket, and open this up
404 * socket units: support creating sockets in different namespace,
405 opening it up for JoinsNamespaceOf=. This would require to fork off
406 a tiny process that joins the namespace and creates/binds the socket
407 and passes this back to PID1 via SCM_RIGHTS. This also could be used
408 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
410 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
411 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
412 should SIGSTOP all unit processes in a loop until all processes of
413 it are fully stopped. This can later be used for app management by
414 desktop UIs such as gnome-shell to freeze apps that are not visible
415 on screen, not unlike how job control works on the shell
418 - implement per-slice CPUFairScheduling=1 switch
419 - handle jointly mounted controllers correctly
420 - introduce high-level settings for RT budget, swappiness
421 - how to reset dynamically changed unit cgroup attributes sanely?
422 - when reloading configuration, apply new cgroup configuration
423 - when recursively showing the cgroup hierarchy, optionally also show
424 the hierarchies of child processes
427 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
428 - ensure scope units may be started only a single time
430 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
432 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
434 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
436 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
438 * 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
440 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
442 * If we try to find a unit via a dangling symlink, generate a clean
443 error. Currently, we just ignore it and read the unit from the search
446 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
448 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
450 * load .d/*.conf dropins for device units
452 * allow implementation of InaccessibleDirectories=/ plus
453 ReadOnlyDirectories=... for whitelisting files for a service.
457 - GetAllProperties() on a non-existing object does not result in a failure currently
458 - port to sd-resolve for connecting to TCP dbus servers
459 - 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
460 - see if we can drop more message validation on the sending side
461 - add API to clone sd_bus_message objects
462 - make AddMatch calls on dbus1 transports async?
463 - longer term: priority inheritance
465 - NameLost/NameAcquired obsolete
468 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
469 - test bloom filter generation indexes
472 - allow multiple signal handlers per signal?
473 - document chaining of signal handler for SIGCHLD and child handlers
474 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
475 - generate a failure of a default event loop is executed out-of-thread
476 - maybe add support for inotify events
478 * investigate endianness issues of UUID vs. GUID
480 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
481 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
483 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
485 * add a pam module that on password changes updates any LUKS slot where the password matches
487 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
490 - add 'set -e' to scripts in test/
491 - make stuff in test/ work with separate output dir
493 * seems that when we follow symlinks to units we prefer the symlink
494 destination path over /etc and /usr. We should not do that. Instead
495 /etc should always override /run+/usr and also any symlink
498 * when isolating, try to figure out a way how we implicitly can order
499 all units we stop before the isolating unit...
501 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
503 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
504 that the boot loader should be installed to the ESP. Define a way
505 how an installer can figure out whether a BLS compliant boot loader
508 * think about requeuing jobs when daemon-reload is issued? usecase:
509 the initrd issues a reload after fstab from the host is accessible
510 and we might want to requeue the mounts local-fs acquired through
513 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
515 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
517 * shutdown logging: store to EFI var, and store to USB stick?
519 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
521 * merge unit_kill_common() and unit_kill_context()
523 * introduce ExecCondition= in services
526 - honor language efi variables for default language selection (if there are any?)
527 - honor timezone efi variables for default timezone selection (if there are any?)
528 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
530 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
532 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
534 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
537 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
538 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
539 - logind: wakelock/opportunistic suspend support
540 - Add pretty name for seats in logind
541 - logind: allow showing logout dialog from system?
542 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
543 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
544 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
545 - if pam_systemd is invoked by su from a process that is outside of a
546 any session we should probably just become a NOP, since that's
547 usually not a real user session but just some system code that just
549 - logind: make the Suspend()/Hibernate() bus calls wait for the for
550 the job to be completed. before returning, so that clients can wait
551 for "systemctl suspend" to finish to know when the suspending is
553 - logind: when the power button is pressed short, just popup a
554 logout dialog. If it is pressed for 1s, do the usual
555 shutdown. Inspiration are Macs here.
556 - expose "Locked" property on logind sesison objects
557 - given that logind now lets PID 1 do all nasty work, we can
558 probably reduce the capability set it retains substantially.
559 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
560 - expose orientation sensors and tablet mode through logind
561 - maybe allow configuration of the StopTimeout for session scopes
562 - rename session scope so that it includes the UID. THat way
563 the session scope can be arranged freely in slices and we don't have
564 make assumptions about their slice anymore.
565 - follow PropertiesChanged state more closely, to deal with quick logouts and
568 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
570 * service: watchdog logic: for testing purposes allow ping, but do not require pong
573 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
574 - import and delete pstore filesystem content at startup
575 - journald: also get thread ID from client, plus thread name
576 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
577 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
578 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
579 - declare the local journal protocol stable in the wiki interface chart
580 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
581 - journald: when dropping msgs due to ratelimit make sure to write
582 "dropped %u messages" not only when we are about to print the next
583 message that works, but alraedy after a short tiemout
584 - check if we can make journalctl by default use --follow mode inside of less if called without args?
585 - maybe add API to send pairs of iovecs via sd_journal_send
586 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
587 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
588 and !FOOBAR for events without FOOBAR.
589 - journal: store timestamp of journal_file_set_offline() int he header,
590 so it is possible to display when the file was last synced.
591 - 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.
592 - journal: find a way to allow dropping history early, based on priority, other rules
593 - journal: When used on NFS, check payload hashes
594 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
595 - refuse taking lower-case variable names in sd_journal_send() and friends.
596 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
597 - journal: deal nicely with byte-by-byte copied files, especially regards header
598 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
599 - Replace utmp, wtmp, btmp, and lastlog completely with journal
600 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
601 - when a kernel driver logs in a tight loop, we should ratelimit that too.
602 - journald: optionally, log debug messages to /run but everything else to /var
603 - journald: when we drop syslog messages because the syslog socket is
604 full, make sure to write how many messages are lost as first thing
605 to syslog when it works again.
606 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
607 - change systemd-journal-flush into a service that stays around during
608 boot, and causes the journal to be moved back to /run on shutdown,
609 so that we do not keep /var busy. This needs to happen synchronously,
610 hence doing this via signals is not going to work.
611 - optionally support running journald from the command line for testing purposes in external projects
612 - journald: allow per-priority and per-service retention times when rotating/vacuuming
613 - journald: make use of uid-range.h to managed uid ranges to split
615 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
616 - improve journalctl performance by loading journal files
617 lazily. Encode just enough information in the file name, so that we
618 do not have to open it to know that it is not interesting for us, for
619 the most common operations.
620 - journal-or-kmsg is currently broken? See reverted
621 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
622 - man: document that corrupted journal files is nothing to act on
623 - rework journald sigbus stuff to use mutex
624 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
625 services that run under their own user ids, and use User= (but only
626 in a world where userns is ubiquitous since otherwise we cannot
627 invoke those daemons on the host AND in a container anymore). Also,
628 if LimitNPROC= is used without User= we should warn and refuse
630 - journalctl --verify: don't show files that are currently being
631 written to as FAIL, but instead show that their are being written to.
632 - add journalctl -H that talks via ssh to a remote peer and passes through
634 - add a version of --merge which also merges /var/log/journal/remote
635 - log accumulated resource usage after each service invocation
636 - journalctl: -m should access container journals directly by enumerating
637 them via machined, and also watch containers coming and going.
638 Benefit: nspawn --ephemeral would start working nicely with the journal.
639 - assign MESSAGE_ID to log messages about failed services
642 - document that deps in [Unit] sections ignore Alias= fields in
643 [Install] units of other units, unless those units are disabled
644 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
645 - document the exit codes when services fail before they are exec()ed
646 - document that service reload may be implemented as service reexec
647 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
648 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
649 - document systemd-journal-flush.service properly
650 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
651 - man: document the very specific env the shutdown drop-in tools live in
652 - man: add more examples to man pages
653 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
656 - add systemctl switch to dump transaction without executing it
657 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
658 - "systemctl disable" on a static unit prints no message and does
659 nothing. "systemctl enable" does nothing, and gives a bad message
660 about it. Should fix both to print nice actionable messages.
661 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
662 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
663 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
664 - systemctl: "Journal has been rotated since unit was started." message is misleading
665 - better error message if you run systemctl without systemd running
666 - systemctl status output should include list of triggering units and their status
669 - "systemctl mask" should find all names by which a unit is accessible
670 (i.e. by scanning for symlinks to it) and link them all to /dev/null
673 - timer units should get the ability to trigger when:
674 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
676 - Modulate timer frequency based on battery state
678 * add libsystemd-password or so to query passwords during boot using the password agent logic
680 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
682 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
684 * make repeated alt-ctrl-del presses printing a dump
686 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
688 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
691 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
692 with seccomp. That should provide us with a useful log buffer that
693 systemd can log to during early boot, and disconnect container logs
694 from the kernel's logs.
695 - as soon as networkd has a bus interface, hook up --network-interface=,
696 --network-bridge= with networkd, to trigger netdev creation should an
698 - a nice way to boot up without machine id set, so that it is set at boot
699 automatically for supporting --ephemeral. Maybe hash the host machine id
700 together with the machine name to generate the machine id for the container
701 - fix logic always print a final newline on output.
702 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
703 - should optionally support receiving WATCHDOG=1 messages from its payload
705 - should send out sd_notify("WATCHDOG=1") messages
706 - optionally automatically add FORWARD rules to iptables whenever nspawn is
707 running, remove them when shut down.
708 - Improve error message when --bind= is used on a non-existing source
710 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
714 - refuse mounting over a mount point
715 - automatically discover .roothash files in dissect, similarly to nspawn
718 - add an API so that libvirt-lxc can inform us about network interfaces being
719 removed or added to an existing machine
720 - "machinectl migrate" or similar to copy a container from or to a
721 difference host, via ssh
722 - introduce systemd-nspawn-ephemeral@.service, and hook it into
723 "machinectl start" with a new --ephemeral switch
724 - "machinectl status" should also show internal logs of the container in
726 - "machinectl list-images" should show os-release data, as well as
727 machine-info data (including deployment level)
728 - "machinectl history"
730 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
731 shell in it, and marks it read-only after use
734 - generate a nice warning if mkfs.btrfs is missing
737 - cryptsetup-generator: allow specification of passwords in crypttab itself
738 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
740 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
741 https://bugs.freedesktop.org/show_bug.cgi?id=54712
743 * create /sbin/init symlinks from the build system
745 * add a dependency on standard-conf.xml and other included files to man pages
747 * MountFlags=shared acts as MountFlags=slave right now.
749 * properly handle loop back mounts via fstab, especially regards to fsck/passno
751 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
756 - add trigger --subsystem-match=usb/usb_device device
757 - reimport udev db after MOVE events for devices without dev_t
759 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
761 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
764 - save coredump in Windows/Mozilla minidump format
765 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
767 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
769 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
771 * be able to specify a forced restart of service A where service B depends on, in case B
772 needs to be auto-respawned?
775 - apply "x" on "D" too (see patch from William Douglas)
777 - instead of ignoring unknown fields, reject them.
778 - creating new directories/subvolumes/fifos/device nodes
779 should not follow symlinks. None of the other adjustment or creation
780 calls follow symlinks.
782 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
784 * verify that the AF_UNIX sockets of a service in the fs still exist
785 when we start a service in order to avoid confusion when a user
786 assumes starting a service is enough to make it accessible
788 * Make it possible to set the keymap independently from the font on
789 the kernel cmdline. Right now setting one resets also the other.
791 * and a dbus call to generate target from current state
793 * write blog stories about:
794 - hwdb: what belongs into it, lsusb
795 - enabling dbus services
797 - how to make changes to sysctl and sysfs attributes
799 - how to pass throw-away units to systemd, or dynamically change properties of existing units
800 - testing with Harald's awesome test kit
802 - how to develop against journal browsing APIs
803 - the journal HTTP iface
804 - non-cgroup resource management
805 - dynamic resource management with cgroups
806 - refreshed, longer missions statement
807 - calendar time events
808 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
809 - how to create your own target
810 - instantiated apache, dovecot and so on
811 - hooking a script into various stages of shutdown/rearly booot
813 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
815 * dot output for --test showing the 'initial transaction'
818 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
819 log both units as UNIT=, so that journalctl -u triggers on both.
820 - generate better errors when people try to set transient properties
821 that are not supported...
822 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
823 - maybe introduce WantsMountsFor=? Usecase:
824 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
825 - recreate systemd's D-Bus private socket file on SIGUSR2
826 - move PAM code into its own binary
827 - when we automatically restart a service, ensure we restart its rdeps, too.
828 - hide PAM options in fragment parser when compile time disabled
829 - Support --test based on current system state
830 - 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().
831 - after deserializing sockets in socket.c we should reapply sockopts and things
832 - drop PID 1 reloading, only do reexecing (difficult: Reload()
833 currently is properly synchronous, Reexec() is weird, because we
834 cannot delay the response properly until we are back, so instead of
835 being properly synchronous we just keep open the fd and close it
836 when done. That means clients do not get a successful method reply,
837 but much rather a disconnect on success.
838 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
839 - when a bus name of a service disappears from the bus make sure to queue further activation requests
842 - allow port=0 in .socket units
843 - maybe introduce ExecRestartPre=
844 - add ReloadSignal= for configuring a reload signal to use
845 - implement Register= switch in .socket units to enable registration
846 in Avahi, RPC and other socket registration services.
847 - allow Type=simple with PIDFile=
848 https://bugzilla.redhat.com/show_bug.cgi?id=723942
849 - allow writing multiple conditions in unit files on one line
850 - load-fragment: when loading a unit file via a chain of symlinks
851 verify that it is not masked via any of the names traversed.
852 - introduce Type=pid-file
853 - introduce mix of BindTo and Requisite
854 - add a concept of RemainAfterExit= to scope units
855 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
858 - Make sure ID_PATH is always exported and complete for
859 network devices where possible, so we can safely rely
861 - check MTUBytes parsing (expecting size_t but we are using unsigned)
864 - add support for more attribute types
865 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
868 - add more keys to [Route] and [Address] sections
869 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
870 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
871 - add reduced [Link] support to .network files
872 - add Scope= parsing option for [Network]
873 - properly handle routerless dhcp leases
874 - work with non-Ethernet devices
875 - add support for more bond options
876 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
877 - the DHCP lease data (such as NTP/DNS) is still made available when
878 a carrier is lost on a link. It should be removed instantly.
879 - expose in the API the following bits:
880 - option 15, domain name and/or option 119, search list
881 - option 12, host name and/or option 81, fqdn
882 - option 123, 144, geolocation
883 - option 252, configure http proxy (PAC/wpad)
884 - provide a way to define a per-network interface default metric value
885 for all routes to it. possibly a second default for DHCP routes.
886 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
887 support Name=foo*|bar*|baz ?
888 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
889 - allow DUID/IAID to be customized, see issue #394.
890 - whenever uplink info changes, make DHCP server send out FORCERENEW
892 * networkd-wait-online:
893 - make operstates to wait for configurable?
896 - figure out how much we can increase Maximum Message Size
899 - add functions to set previously stored IPv6 addresses on startup and get
900 them at shutdown; store them in client->ia_na
901 - write more test cases
902 - implement reconfigure support, see 5.3., 15.11. and 22.20.
903 - implement support for temporary adressess (IA_TA)
904 - implement dhcpv6 authentication
905 - investigate the usefulness of Confirm messages; i.e. are there any
906 situations where the link changes without any loss in carrier detection
908 - some servers don't do rapid commit without a filled in IA_NA, verify
915 - natively watch for dbus-*.service symlinks (PENDING)
916 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
918 * fix alsa mixer restore to not print error when no config is stored
920 * make cryptsetup lower --iter-time
922 * patch kernel for xattr support in /dev, /proc/, /sys?
924 * kernel: add device_type = "fb", "fbcon" to class "graphics"
926 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
928 * /usr/bin/service should actually show the new command line
930 * 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=
932 * fedora: F20: go timer units all the way, leave cron.daily for cron
934 * neither pkexec nor sudo initialize environ[] from the PAM environment?
936 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
938 * register catalog database signature as file magic
940 * zsh shell completion:
941 - <command> <verb> -<TAB> should complete options, but currently does not
942 - systemctl add-wants,add-requires
947 * look for close() vs. close_nointr() vs. close_nointr_nofail()
949 * check for strerror(r) instead of strerror(-r)
951 * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel
955 * set_put(), hashmap_put() return values check. i.e. == 0 does not free()!
957 * use secure_getenv() instead of getenv() where appropriate
959 * link up selected blog stories from man pages and unit files Documentation= fields
