Merge pull request #7637 from yuwata/transient-path
[thirdparty/systemd.git] / TODO
1 Bugfixes:
2
3 * Should systemctl status \* work on all unit types, not just .service?
4
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.
8
9 * ExecStart with unicode characters fails in strv_split_extract:
10
11 [Service]
12 Environment=ONE='one' "TWO='two two' too" THREE=
13 ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE
14
15 External:
16
17 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
18
19 * wiki: update journal format documentation for lz4 additions
20
21 Janitorial Clean-ups:
22
23 * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
24
25 Features:
26
27 * implement transient socket unit.
28
29 * make systemd-run create transient path and socket unit.
30
31 * make use of ethtool veth peer info in machined, for automatically finding out
32 host-side interface pointing to the container.
33
34 * add some special mode to LogsDirectory=/StateDirectory=… that allows
35 declaring these directories without necessarily pulling in deps for them, or
36 creating them when starting up. That way, we could declare that
37 systemd-journald writes to /var/log/journal, which could be useful when we
38 doing disk usage calculations and so on.
39
40 * taint systemd if there are fewer than 65536 users assigned to the system.
41
42 * deprecate PermissionsStartOnly= and RootDirectoryStartOnly= in favour of the ExecStart= prefix chars
43
44 * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
45 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
46 as the unit is running or has a job queued.
47
48 * hook up sd-bus' creds stuff with SO_PEERGROUPS
49
50 * add async version of sd_bus_add_match and make use of that
51
52 * support projid-based quota in machinectl for containers, and then drop
53 implicit btrfs loopback magic in machined
54
55 * Add NetworkNamespacePath= to specify a path to a network namespace
56
57 * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks
58 introduced) as the RTC epoch, instead of the mtime of NEWS.
59
60 * add a way to lock down cgroup migration: a boolean, which when set for a unit
61 makes sure the processes in it can never migrate out of it
62
63 * blog about fd store and restartable services
64
65 * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
66
67 * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
68 magic meaning and is no longer upgraded to something else if set explicitly.
69
70 * in the long run: permit a system with /etc/machine-id linked to /dev/null, to
71 make it lose its identity, i.e. be anonymous. For this we'd have to patch
72 through the whole tree to make all code deal with the case where no machine
73 ID is available.
74
75 * optionally, collect cgroup resource data, and store it in per-unit RRD files,
76 suitable for processing with rrdtool. Add bus API to access this data, and
77 possibly implement a CPULoad property based on it.
78
79 * beef up pam_systemd to take unit file settings such as cgroups properties as
80 parameters
81
82 * a new "systemd-analyze security" tool outputting a checklist of security
83 features a service does and does not implement
84
85 * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
86 the quota of a the user indicated in User= via unit file settings, like the
87 other resource management concepts. Would mix nicely with DynamicUser=1. Or
88 alternatively, do this with projids, so that we can also cover services
89 running as root. Quota should probably cover all the special dirs such as
90 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
91 is set, plus the whole disk space any image configured with RootImage=.
92
93 * Introduce "exit" as an EmergencyAction value, and allow to configure a
94 per-unit success/failure exit code to configure. This would be useful for
95 running commands inside of services inside of containers, which could then
96 propagate their failure state all the way up.
97
98 * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
99 disks to see if the UID is already in use.
100
101 * add dissect_image_warn() as a wrapper around dissect_image() that prints
102 friendly log messages for the returned errors, so that we don't have to
103 duplicate that in nspawn, systemd-dissect and PID 1.
104
105 * add "systemctl wait" or so, which does what "systemd-run --wait" does, but
106 for all units. It should be both a way to pin units into memory as well as a
107 wait to retrieve their exit data.
108
109 * maybe set a new set of env vars for services, based on RuntimeDirectory=,
110 StateDirectory=, LogsDirectory=, CacheDirectory= and ConfigurationDirectory=
111 automatically. For example, there could be $RUNTIME_DIRECTORY,
112 $STATE_DIRECTORY, $LOGS_DIRECTORY=, $CACHE_DIRECTORY and
113 $CONFIGURATION_DIRECTORY or so. This could be useful to write services that
114 can adapt to varying directories for these purposes. Special care has to be
115 taken if multiple dirs are configured. Maybe avoid setting the env vars in
116 that case?
117
118 * expose IO accounting data on the bus, show it in systemd-run --wait and log
119 about it in the resource log message
120
121 * add "systemctl purge" for flushing out configuration, state, logs, ... of a
122 unit when it is stopped
123
124 * show whether a service has out-of-date configuration in "systemctl status" by
125 using mtime data of ConfigurationDirectory=.
126
127 * replace all uses of fgets() + LINE_MAX by read_line()
128
129 * Add AddUser= setting to unit files, similar to DynamicUser=1 which however
130 creates a static, persistent user rather than a dynamic, transient user. We
131 can leverage code from sysusers.d for this.
132
133 * add some optional flag to ReadWritePaths= and friends, that has the effect
134 that we create the dir in question when the service is started. Example:
135
136 ReadWritePaths=:/var/lib/foobar
137
138 * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
139 the sd-journal logging socket, and, if the timeout is set to 0, sets
140 O_NONBLOCK on it. That way people can control if and when to block for
141 logging.
142
143 * tighten sd_notify() MAINPID= checks a bit: don't accept foreign PIDs (i.e.
144 PIDs not managed by the service manager)
145
146 * hostnamed: populate form factor data from a new hwdb database, so that old
147 yogas can be recognized as "convertible" too, even if they predate the DMI
148 "convertible" form factor
149
150 * Maybe add a small tool invoked early at boot, that adds in or resizes
151 partitions automatically, to be used when the media used is actually larger
152 than the image written onto it is.
153
154 * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
155 after all. Be strict however, only support the equivalent of nspawn's
156 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
157 as MAINPID.
158
159 * Add ExecMonitor= setting. May be used multiple times. Forks off a process in
160 the service cgroup, which is supposed to monitor the service, and when it
161 exits the service is considered failed by its monitor.
162
163 * track the per-service PAM process properly (i.e. as an additional control
164 process), so that it may be queried on the bus and everything.
165
166 * add a new "debug" job mode, that is propagated to unit_start() and for
167 services results in two things: we raise SIGSTOP right before invoking
168 execve() and turn off watchdog support. Then, use that to implement
169 "systemd-gdb" for attaching to the start-up of any system service in its
170 natural habitat.
171
172 * replace all canonicalize_file_name() invocations by chase_symlinks(), in
173 particulr those where a rootdir is relevant.
174
175 * maybe introduce gpt auto discovery for /var/tmp?
176
177 * maybe add gpt-partition-based user management: each user gets his own
178 LUKS-encrypted GPT partition with a new GPT type. A small nss module
179 enumerates users via udev partition enumeration. UIDs are assigned in a fixed
180 way: the partition index is added as offset to some fixed base uid. User name
181 is stored in GPT partition name. A PAM module authenticates the user via the
182 LUKS partition password. Benefits: strong per-user security, compatibility
183 with stateless/read-only/verity-enabled root. (other idea: do this based on
184 loopback files in /home, without GPT involvement)
185
186 * gpt-auto logic: introduce support for discovering /var matching an image. For
187 that, use a partition type UUID that is hashed from the OS name (as encoded
188 in /etc/os-release), the architecture, and 4 new bits from the gpt flags
189 field of the root partition. This way can easily support multiple OS
190 installations on the same GPT partition table, without problems with
191 unmatched /var partitions.
192
193 * gpt-auto logic: related to the above, maybe support a "secondary" root
194 partition, that is mounted to / and is writable, and where the actual root's
195 /usr is mounted into.
196
197 * 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
198
199 * drop nss-myhostname in favour of nss-resolve?
200
201 * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
202 then use that for the setting used in user@.service. It should be understood
203 relative to the configured default value.
204
205 * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
206
207 * enable LockMLOCK to take a percentage value relative to physical memory
208
209 * Permit masking specific netlink APIs with RestrictAddressFamily=
210
211 * nspawn: support that /proc, /sys/, /dev are pre-mounted
212
213 * define gpt header bits to select volatility mode
214
215 * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files
216
217 * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
218
219 * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
220
221 * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
222
223 * ProtectKeyRing= to take keyring calls away
224
225 * RemoveKeyRing= to remove all keyring entries of the specified user
226
227 * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
228 on PID 1 with the relevant signals, and makes relevant files in /sys and
229 /proc (such as the sysrq stuff) unavailable
230
231 * DeviceAllow= should also generate seccomp filters for mknod()
232
233 * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
234
235 * journalctl: make sure -f ends when the container indicated by -M terminates
236
237 * mount: automatically search for "main" partition of an image has multiple
238 partitions
239
240 * expose the "privileged" flag of ExecCommand on the bus, and open it up to
241 transient units
242
243 * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
244 find a way to map the User=/Group= of the service to the right name. This way
245 a user/group for a service only has to exist on the host for the right
246 mapping to work.
247
248 * add bus API for creating unit files in /etc, reusing the code for transient units
249
250 * add bus API to remove unit files from /etc
251
252 * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
253
254 * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
255 kernel doesn't support linkat() that replaces existing files, currently)
256
257 * check if DeviceAllow= should split first, resolve specifiers later
258
259 * transient units: don't bother with actually setting unit properties, we
260 reload the unit file anyway
261
262 * journald: sigbus API via a signal-handler safe function that people may call
263 from the SIGBUS handler
264
265 * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
266
267 * resolved: when routing queries, make sure only look for the *longest* suffix...
268
269 * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
270 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
271
272 * cache sd_event_now() result from before the first iteration...
273
274 * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
275
276 * PID1: find a way how we can reload unit file configuration for
277 specific units only, without reloading the whole of systemd
278
279 * add an explicit parser for LimitRTPRIO= that verifies
280 the specified range and generates sane error messages for incorrect
281 specifications.
282
283 * when we detect that there are waiting jobs but no running jobs, do something
284
285 * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy)
286
287 * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
288
289 * there's probably something wrong with having user mounts below /sys,
290 as we have for debugfs. for exmaple, src/core/mount.c handles mounts
291 prefixed with /sys generally special.
292 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
293
294 * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
295
296 * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
297
298 * mounting and unmounting mount points manually with different source
299 devices will result in collected on all devices used.
300 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html
301
302 * add a job mode that will fail if a transaction would mean stopping
303 running units. Use this in timedated to manage the NTP service
304 state.
305 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
306
307 * Maybe add support for the equivalent of "ethtool advertise" to .link files?
308 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html
309
310 * The udev blkid built-in should expose a property that reflects
311 whether media was sensed in USB CF/SD card readers. This should then
312 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
313 picked up by systemd unless they contain a medium. This would mirror
314 the behaviour we already have for CD drives.
315
316 * networkd/udev: implement SR_IOV configuration in .link files:
317 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
318
319 * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API
320
321 * Port various tools to make use of verbs.[ch], where applicable: busctl,
322 coredumpctl, hostnamectl, localectl, systemd-analyze, timedatectl
323
324 * hostnamectl: show root image uuid
325
326 * sysfs set api in libudev is not const
327
328 * Find a solution for SMACK capabilities stuff:
329 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
330
331 * "systemctl preset-all" should probably order the unit files it
332 operates on lexicographically before starting to work, in order to
333 ensure deterministic behaviour if two unit files conflict (like DMs
334 do, for example)
335
336 * synchronize console access with BSD locks:
337 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
338
339 * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
340 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
341
342 * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column
343
344 * figure out when we can use the coarse timers
345
346 * add "systemctl start -v foobar.service" that shows logs of a service
347 while the start command runs. This is non-trivial to do without
348 races though, since we should flush out all journal messages before
349 returning from the "systemctl stop".
350
351 * 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
352
353 * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
354
355 * introduce systemd-timesync-wait.service or so to sync on an NTP fix?
356
357 * consider showing the unit names during boot up in the status output, not just the unit descriptions
358
359 * maybe allow timer units with an empty Units= setting, so that they
360 can be used for resuming the system but nothing else.
361
362 * what to do about udev db binary stability for apps? (raw access is not an option)
363
364 * maybe provide an API to allow migration of foreign PIDs into existing scopes.
365
366 * man: maybe use the word "inspect" rather than "introspect"?
367
368 * systemctl: if some operation fails, show log output?
369
370 * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #.
371 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
372
373 * exponential backoff in timesyncd when we cannot reach a server
374
375 * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
376
377 * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
378
379 * systemd.show_status= should probably have a mode where only failed
380 units are shown.
381
382 * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
383 (throughout the codebase, not only PID1)
384
385 * resolved:
386 - mDNS/DNS-SD
387 - service registration
388 - service/domain/types browsing
389 - avahi compat
390 - DNS-SD service registration from socket units
391 - resolved should optionally register additional per-interface LLMNR
392 names, so that for the container case we can establish the same name
393 (maybe "host") for referencing the server, everywhere.
394 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
395 - hook up resolved with machined-based address resolution
396
397 * refcounting in sd-resolve is borked
398
399 * Add a new verb "systemctl top"
400
401 * add new gpt type for btrfs volumes
402
403 * support empty /etc boots nicely:
404 - nspawn/gpt-generator: introduce new gpt partition type for /usr
405
406 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
407
408 * a way for container managers to turn off getty starting via $container_headless= or so...
409
410 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
411
412 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
413 they run added to the initial transaction and thus confuse Type=idle.
414
415 * add bus api to query unit file's X fields.
416
417 * gpt-auto-generator:
418 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
419 - Make /home automount rather than mount?
420
421 * add generator that pulls in systemd-network from containers when
422 CAP_NET_ADMIN is set, more than the loopback device is defined, even
423 when it is otherwise off
424
425 * MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
426
427 * implement Distribute= in socket units to allow running multiple
428 service instances processing the listening socket, and open this up
429 for ReusePort=
430
431 * socket units: support creating sockets in different namespace,
432 opening it up for JoinsNamespaceOf=. This would require to fork off
433 a tiny process that joins the namespace and creates/binds the socket
434 and passes this back to PID1 via SCM_RIGHTS. This also could be used
435 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
436
437 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
438 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
439 should SIGSTOP all unit processes in a loop until all processes of
440 it are fully stopped. This can later be used for app management by
441 desktop UIs such as gnome-shell to freeze apps that are not visible
442 on screen, not unlike how job control works on the shell
443
444 * cgroups:
445 - implement per-slice CPUFairScheduling=1 switch
446 - handle jointly mounted controllers correctly
447 - introduce high-level settings for RT budget, swappiness
448 - how to reset dynamically changed unit cgroup attributes sanely?
449 - when reloading configuration, apply new cgroup configuration
450 - when recursively showing the cgroup hierarchy, optionally also show
451 the hierarchies of child processes
452
453 * transient units:
454 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
455 - ensure scope units may be started only a single time
456
457 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
458
459 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
460
461 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
462
463 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
464
465 * 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
466
467 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
468
469 * If we try to find a unit via a dangling symlink, generate a clean
470 error. Currently, we just ignore it and read the unit from the search
471 path anyway.
472
473 * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
474
475 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
476
477 * load .d/*.conf dropins for device units
478
479 * allow implementation of InaccessibleDirectories=/ plus
480 ReadOnlyDirectories=... for whitelisting files for a service.
481
482 * sd-bus:
483 - EBADSLT handling
484 - GetAllProperties() on a non-existing object does not result in a failure currently
485 - port to sd-resolve for connecting to TCP dbus servers
486 - 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
487 - see if we can drop more message validation on the sending side
488 - add API to clone sd_bus_message objects
489 - make AddMatch calls on dbus1 transports async?
490 - longer term: priority inheritance
491 - dbus spec updates:
492 - NameLost/NameAcquired obsolete
493 - GVariant
494 - path escaping
495 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
496 - test bloom filter generation indexes
497
498 * sd-event
499 - allow multiple signal handlers per signal?
500 - document chaining of signal handler for SIGCHLD and child handlers
501 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
502 - generate a failure of a default event loop is executed out-of-thread
503 - maybe add support for inotify events
504
505 * investigate endianness issues of UUID vs. GUID
506
507 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
508 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
509
510 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
511
512 * add a pam module that on password changes updates any LUKS slot where the password matches
513
514 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
515
516 * test/:
517 - add 'set -e' to scripts in test/
518 - make stuff in test/ work with separate output dir
519
520 * seems that when we follow symlinks to units we prefer the symlink
521 destination path over /etc and /usr. We should not do that. Instead
522 /etc should always override /run+/usr and also any symlink
523 destination.
524
525 * when isolating, try to figure out a way how we implicitly can order
526 all units we stop before the isolating unit...
527
528 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
529
530 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
531 that the boot loader should be installed to the ESP. Define a way
532 how an installer can figure out whether a BLS compliant boot loader
533 is installed.
534
535 * think about requeuing jobs when daemon-reload is issued? usecase:
536 the initrd issues a reload after fstab from the host is accessible
537 and we might want to requeue the mounts local-fs acquired through
538 that automatically.
539
540 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
541
542 * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
543
544 * shutdown logging: store to EFI var, and store to USB stick?
545
546 * merge unit_kill_common() and unit_kill_context()
547
548 * introduce ExecCondition= in services
549
550 * EFI:
551 - honor language efi variables for default language selection (if there are any?)
552 - honor timezone efi variables for default timezone selection (if there are any?)
553 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
554
555 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
556
557 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
558
559 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
560
561 * logind:
562 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
563 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
564 - logind: wakelock/opportunistic suspend support
565 - Add pretty name for seats in logind
566 - logind: allow showing logout dialog from system?
567 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
568 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
569 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
570 - if pam_systemd is invoked by su from a process that is outside of a
571 any session we should probably just become a NOP, since that's
572 usually not a real user session but just some system code that just
573 needs setuid().
574 - logind: make the Suspend()/Hibernate() bus calls wait for the for
575 the job to be completed. before returning, so that clients can wait
576 for "systemctl suspend" to finish to know when the suspending is
577 complete.
578 - logind: when the power button is pressed short, just popup a
579 logout dialog. If it is pressed for 1s, do the usual
580 shutdown. Inspiration are Macs here.
581 - expose "Locked" property on logind sesison objects
582 - given that logind now lets PID 1 do all nasty work, we can
583 probably reduce the capability set it retains substantially.
584 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
585 - expose orientation sensors and tablet mode through logind
586 - maybe allow configuration of the StopTimeout for session scopes
587 - rename session scope so that it includes the UID. THat way
588 the session scope can be arranged freely in slices and we don't have
589 make assumptions about their slice anymore.
590 - follow PropertiesChanged state more closely, to deal with quick logouts and
591 relogins
592
593 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
594
595 * service: watchdog logic: for testing purposes allow ping, but do not require pong
596
597 * journal:
598 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
599 - import and delete pstore filesystem content at startup
600 - journald: also get thread ID from client, plus thread name
601 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
602 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
603 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
604 - declare the local journal protocol stable in the wiki interface chart
605 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
606 - journald: when dropping msgs due to ratelimit make sure to write
607 "dropped %u messages" not only when we are about to print the next
608 message that works, but alraedy after a short tiemout
609 - check if we can make journalctl by default use --follow mode inside of less if called without args?
610 - maybe add API to send pairs of iovecs via sd_journal_send
611 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
612 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
613 and !FOOBAR for events without FOOBAR.
614 - journal: store timestamp of journal_file_set_offline() int he header,
615 so it is possible to display when the file was last synced.
616 - 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.
617 - journal: find a way to allow dropping history early, based on priority, other rules
618 - journal: When used on NFS, check payload hashes
619 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
620 - refuse taking lower-case variable names in sd_journal_send() and friends.
621 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
622 - journal: deal nicely with byte-by-byte copied files, especially regards header
623 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
624 - Replace utmp, wtmp, btmp, and lastlog completely with journal
625 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
626 - when a kernel driver logs in a tight loop, we should ratelimit that too.
627 - journald: optionally, log debug messages to /run but everything else to /var
628 - journald: when we drop syslog messages because the syslog socket is
629 full, make sure to write how many messages are lost as first thing
630 to syslog when it works again.
631 - change systemd-journal-flush into a service that stays around during
632 boot, and causes the journal to be moved back to /run on shutdown,
633 so that we do not keep /var busy. This needs to happen synchronously,
634 hence doing this via signals is not going to work.
635 - optionally support running journald from the command line for testing purposes in external projects
636 - journald: allow per-priority and per-service retention times when rotating/vacuuming
637 - journald: make use of uid-range.h to managed uid ranges to split
638 journals in.
639 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
640 - improve journalctl performance by loading journal files
641 lazily. Encode just enough information in the file name, so that we
642 do not have to open it to know that it is not interesting for us, for
643 the most common operations.
644 - journal-or-kmsg is currently broken? See reverted
645 commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
646 - man: document that corrupted journal files is nothing to act on
647 - rework journald sigbus stuff to use mutex
648 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
649 services that run under their own user ids, and use User= (but only
650 in a world where userns is ubiquitous since otherwise we cannot
651 invoke those daemons on the host AND in a container anymore). Also,
652 if LimitNPROC= is used without User= we should warn and refuse
653 operation.
654 - journalctl --verify: don't show files that are currently being
655 written to as FAIL, but instead show that their are being written to.
656 - add journalctl -H that talks via ssh to a remote peer and passes through
657 binary logs data
658 - add a version of --merge which also merges /var/log/journal/remote
659 - journalctl: -m should access container journals directly by enumerating
660 them via machined, and also watch containers coming and going.
661 Benefit: nspawn --ephemeral would start working nicely with the journal.
662 - assign MESSAGE_ID to log messages about failed services
663
664 * add a test if all entries in the catalog are properly formatted.
665 (Adding dashes in a catalog entry currently results in the catalog entry
666 being silently skipped. journalctl --update-catalog must warn about this,
667 and we should also have a unit test to check that all our message are OK.)
668
669 * document:
670 - document that deps in [Unit] sections ignore Alias= fields in
671 [Install] units of other units, unless those units are disabled
672 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
673 - document that service reload may be implemented as service reexec
674 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
675 - document systemd-journal-flush.service properly
676 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
677 - man: document the very specific env the shutdown drop-in tools live in
678 - man: add more examples to man pages
679 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
680
681 * systemctl:
682 - add systemctl switch to dump transaction without executing it
683 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
684 - "systemctl disable" on a static unit prints no message and does
685 nothing. "systemctl enable" does nothing, and gives a bad message
686 about it. Should fix both to print nice actionable messages.
687 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
688 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
689 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
690 - systemctl: "Journal has been rotated since unit was started." message is misleading
691 - systemctl status output should include list of triggering units and their status
692
693 * unit install:
694 - "systemctl mask" should find all names by which a unit is accessible
695 (i.e. by scanning for symlinks to it) and link them all to /dev/null
696
697 * timer units:
698 - timer units should get the ability to trigger when:
699 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
700 o DST changes
701 - Modulate timer frequency based on battery state
702
703 * add libsystemd-password or so to query passwords during boot using the password agent logic
704
705 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
706
707 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
708
709 * make repeated alt-ctrl-del presses printing a dump
710
711 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
712
713 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
714
715 * nspawn:
716 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
717 with seccomp. That should provide us with a useful log buffer that
718 systemd can log to during early boot, and disconnect container logs
719 from the kernel's logs.
720 - as soon as networkd has a bus interface, hook up --network-interface=,
721 --network-bridge= with networkd, to trigger netdev creation should an
722 interface be missing
723 - a nice way to boot up without machine id set, so that it is set at boot
724 automatically for supporting --ephemeral. Maybe hash the host machine id
725 together with the machine name to generate the machine id for the container
726 - fix logic always print a final newline on output.
727 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
728 - should optionally support receiving WATCHDOG=1 messages from its payload
729 PID 1...
730 - optionally automatically add FORWARD rules to iptables whenever nspawn is
731 running, remove them when shut down.
732 - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only
733 is used
734
735 * dissect
736 - refuse mounting over a mount point
737 - automatically discover .roothash files in dissect, similarly to nspawn
738
739 * machined:
740 - add an API so that libvirt-lxc can inform us about network interfaces being
741 removed or added to an existing machine
742 - "machinectl migrate" or similar to copy a container from or to a
743 difference host, via ssh
744 - introduce systemd-nspawn-ephemeral@.service, and hook it into
745 "machinectl start" with a new --ephemeral switch
746 - "machinectl status" should also show internal logs of the container in
747 question
748 - "machinectl list-images" should show os-release data, as well as
749 machine-info data (including deployment level)
750 - "machinectl history"
751 - "machinectl diff"
752 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
753 shell in it, and marks it read-only after use
754
755 * importd:
756 - generate a nice warning if mkfs.btrfs is missing
757
758 * cryptsetup:
759 - cryptsetup-generator: allow specification of passwords in crypttab itself
760 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
761
762 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
763 https://bugs.freedesktop.org/show_bug.cgi?id=54712
764
765 * create /sbin/init symlinks from the build system
766
767 * add a dependency on standard-conf.xml and other included files to man pages
768
769 * MountFlags=shared acts as MountFlags=slave right now.
770
771 * properly handle loop back mounts via fstab, especially regards to fsck/passno
772
773 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
774
775 * udev:
776 - move to LGPL
777 - kill scsi_id
778 - add trigger --subsystem-match=usb/usb_device device
779 - reimport udev db after MOVE events for devices without dev_t
780
781 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
782
783 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
784
785 * coredump:
786 - save coredump in Windows/Mozilla minidump format
787 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
788
789 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
790
791 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
792
793 * be able to specify a forced restart of service A where service B depends on, in case B
794 needs to be auto-respawned?
795
796 * tmpfiles:
797 - apply "x" on "D" too (see patch from William Douglas)
798 - replace F with f+.
799 - instead of ignoring unknown fields, reject them.
800 - creating new directories/subvolumes/fifos/device nodes
801 should not follow symlinks. None of the other adjustment or creation
802 calls follow symlinks.
803
804 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
805
806 * verify that the AF_UNIX sockets of a service in the fs still exist
807 when we start a service in order to avoid confusion when a user
808 assumes starting a service is enough to make it accessible
809
810 * Make it possible to set the keymap independently from the font on
811 the kernel cmdline. Right now setting one resets also the other.
812
813 * and a dbus call to generate target from current state
814
815 * write blog stories about:
816 - hwdb: what belongs into it, lsusb
817 - enabling dbus services
818 - how to make changes to sysctl and sysfs attributes
819 - remote access
820 - how to pass throw-away units to systemd, or dynamically change properties of existing units
821 - testing with Harald's awesome test kit
822 - auto-restart
823 - how to develop against journal browsing APIs
824 - the journal HTTP iface
825 - non-cgroup resource management
826 - dynamic resource management with cgroups
827 - refreshed, longer missions statement
828 - calendar time events
829 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
830 - how to create your own target
831 - instantiated apache, dovecot and so on
832 - hooking a script into various stages of shutdown/rearly booot
833
834 * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
835
836 * dot output for --test showing the 'initial transaction'
837
838 * pid1:
839 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
840 log both units as UNIT=, so that journalctl -u triggers on both.
841 - generate better errors when people try to set transient properties
842 that are not supported...
843 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
844 - maybe introduce WantsMountsFor=? Usecase:
845 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
846 - recreate systemd's D-Bus private socket file on SIGUSR2
847 - move PAM code into its own binary
848 - when we automatically restart a service, ensure we restart its rdeps, too.
849 - hide PAM options in fragment parser when compile time disabled
850 - Support --test based on current system state
851 - 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().
852 - after deserializing sockets in socket.c we should reapply sockopts and things
853 - drop PID 1 reloading, only do reexecing (difficult: Reload()
854 currently is properly synchronous, Reexec() is weird, because we
855 cannot delay the response properly until we are back, so instead of
856 being properly synchronous we just keep open the fd and close it
857 when done. That means clients do not get a successful method reply,
858 but much rather a disconnect on success.
859 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
860 - when a bus name of a service disappears from the bus make sure to queue further activation requests
861
862 * unit files:
863 - allow port=0 in .socket units
864 - maybe introduce ExecRestartPre=
865 - add ReloadSignal= for configuring a reload signal to use
866 - implement Register= switch in .socket units to enable registration
867 in Avahi, RPC and other socket registration services.
868 - allow Type=simple with PIDFile=
869 https://bugzilla.redhat.com/show_bug.cgi?id=723942
870 - allow writing multiple conditions in unit files on one line
871 - load-fragment: when loading a unit file via a chain of symlinks
872 verify that it is not masked via any of the names traversed.
873 - introduce Type=pid-file
874 - introduce mix of BindTo and Requisite
875 - add a concept of RemainAfterExit= to scope units
876 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
877
878 * udev-link-config:
879 - Make sure ID_PATH is always exported and complete for
880 network devices where possible, so we can safely rely
881 on Path= matching
882 - check MTUBytes parsing (expecting size_t but we are using unsigned)
883
884 * sd-rtnl:
885 - add support for more attribute types
886 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
887
888 * networkd:
889 - add more keys to [Route] and [Address] sections
890 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
891 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
892 - add reduced [Link] support to .network files
893 - add Scope= parsing option for [Network]
894 - properly handle routerless dhcp leases
895 - work with non-Ethernet devices
896 - add support for more bond options
897 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
898 - the DHCP lease data (such as NTP/DNS) is still made available when
899 a carrier is lost on a link. It should be removed instantly.
900 - expose in the API the following bits:
901 - option 15, domain name and/or option 119, search list
902 - option 12, host name and/or option 81, fqdn
903 - option 123, 144, geolocation
904 - option 252, configure http proxy (PAC/wpad)
905 - provide a way to define a per-network interface default metric value
906 for all routes to it. possibly a second default for DHCP routes.
907 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
908 support Name=foo*|bar*|baz ?
909 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
910 - allow DUID/IAID to be customized, see issue #394.
911 - whenever uplink info changes, make DHCP server send out FORCERENEW
912
913 * networkd-wait-online:
914 - make operstates to wait for configurable?
915
916 * dhcp:
917 - figure out how much we can increase Maximum Message Size
918
919 * dhcp6:
920 - add functions to set previously stored IPv6 addresses on startup and get
921 them at shutdown; store them in client->ia_na
922 - write more test cases
923 - implement reconfigure support, see 5.3., 15.11. and 22.20.
924 - implement support for temporary adressess (IA_TA)
925 - implement dhcpv6 authentication
926 - investigate the usefulness of Confirm messages; i.e. are there any
927 situations where the link changes without any loss in carrier detection
928 or interface down
929 - some servers don't do rapid commit without a filled in IA_NA, verify
930 this behavior
931 - RouteTable= ?
932
933 External:
934
935 * dbus:
936 - natively watch for dbus-*.service symlinks (PENDING)
937 - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
938
939 * fix alsa mixer restore to not print error when no config is stored
940
941 * make cryptsetup lower --iter-time
942
943 * patch kernel for xattr support in /dev, /proc/, /sys?
944
945 * kernel: add device_type = "fb", "fbcon" to class "graphics"
946
947 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
948
949 * /usr/bin/service should actually show the new command line
950
951 * 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=
952
953 * fedora: F20: go timer units all the way, leave cron.daily for cron
954
955 * neither pkexec nor sudo initialize environ[] from the PAM environment?
956
957 * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it
958
959 * register catalog database signature as file magic
960
