3* Many manager configuration settings that are only applicable to user
4 manager or system manager can be always set. It would be better to reject
5 them when parsing config.

f38afcd0 9* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.

11Janitorial Clean-ups:
12
5e524b40
LP
13* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
14
bb527e11
LP
15* rework mount.c and swap.c to follow proper state enumeration/deserialization
16 semantics, like we do for device.c now
17

LP
18Features:
19
4c150809
LP
20* add --copy-from and --copy-to command to systemd-dissect which copies stuff
21 in and out of a disk image
22
707dc794
LP
23* add systemd.random_seed= on the kernel cmdline, taking some hex or base64
24 encoded data. During earliest boot, credit it to entropy. This is not useful
25 for general purpose systems, but certainly for testing environments in VMs
26 and such, as it allows us to boot up instantly with fully initialized entropy
27 pool even if RNG pass-thru is not available.
28
29* Support ProtectProc= or so, using: https://patchwork.kernel.org/cover/11310197/
30
effefa30
LP
31* if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it
32
e78228b1
LP
33* warn if User=nobody is used in a unit file. It's the overflow UID after all,
34 and the service might thus get access to files it really should not get
35 access to on NFS and userns environments.
36
6ae8c6f5
LP
37* build short web pages out of each catalog entry, build them along with man
38 pages, and include hyperlinks to them in the journal output
39
d08a6ec3
LP
40* machined: add API to acquire UID range. add API to mount/dissect loopback
41 file. Both protected by PK. Then make nspawn use these APIs to run
42 unprivileged containers. i.e. push the truly privileged bits into machined,
43 so that the client side can remain entirely unprivileged, with SUID or
44 anything like that.
45
5c0102f8
LP
46* journald: do journal file writing out-of-process, with one writer process per
47 client UID, so tht synthetic hash table collisions can slow down a specific
48 user's journal stream down but not the others.
49
34d16bad
LP
50* add "throttling" to sd-event event sources: optionally, when we wake up too
51 often for one, let's turn it off entirely for a while. Use that for the
52 /proc/self/mountinfo logic.
53
3d9237d6
LP
54* move our systemd-user PAM snippet to /usr/, which PAM appears to support
55 these days
56
f1eb0ccd
LP
57* nspawn: support time namespaces
58
2d2d7504
LP
59* add ConditionSecurity=tpm2
60
42ba8d25
LP
61* Remove any support for booting without /usr pre-mounted in the initrd entirely.
62 Update INITRD_INTERFACE.md accordingly.
63
f1eb0ccd
LP
64* pid1: Move to tracking of main pid/control pid of units per pidfd
65
66* pid1: support new clone3() fork-into-cgroup feature
67
7cc8fb3e
LP
68* pid1: also remove PID files of a service when the service starts, not just
69 when it exits
70
cdfd8537
LP
71* make us use dynamically fewer deps for containers in general purpose distros:
72 o turn into dlopen() deps:
73 - pcre2 (always) — irrelevant on Fedora, since dep by
74 libselinux, but should benefit Debian
75 - libpwquality (always) - only relevant for homed, and maybe soon
76 firstboot
77 - elfutils (always)
78 - p11-kit-trust (always)
79 - kmod-libs (only when called from PID 1)
80 - cryptsetup-libs (only in RootImage= handling in PID 1, but not in systemd-cryptsetup)
81 - similar: libblkid
82 - libpam (only when called from PID 1)
83 - bzip2, xz, lz4 (always — gzip and zstd should probably stay static deps the way they are,
84 since they are so basic and our defaults)
85 o move into separate libsystemd-shared-iptables.so .so
86 - iptables-libs (only used by nspawn + networkd)
87
77169ed0
LP
88* seccomp: when SystemCallArchitectures=native is set then don't install any
89 other seccomp filters for any of the other archs, in order to reduce the
90 number of seccomp filters we install needlessly.
91
92* seccomp: maybe use seccomp_merge() to merge our filters per-arch if we can.
93 Apparently kernel performance is much better with fewer larger seccomp
94 filters than with more smaller seccomp filters.
95
bfafec25
LP
96* systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
97 mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
98
7cc8fb3e
LP
99* make "systemd-dissect" an official supported tool, i.e. move to /usr/bin/ and
100 provide man page. Given that we now have a tool that can generate images like
101 this, it's useful to have one that can dump contents of them, too.
102
a6e1018d
LP
103* All tools that support --root= should also learn --image= so that they can
104 operate on disk images directly. Specifically: bootctl, firstboot, tmpfiles,
105 sysusers, systemctl, repart, journalctl, coredumpctl.
106
112bed84
LP
107* seccomp: by default mask x32 ABI system wide on x86-64. it's on its way out
108
109* seccomp: don't install filters for ABIs that are masked anyway for the
110 specific service
111
112* seccomp: maybe merge all filters we install into one with that libseccomp API that allows merging.
113
a6e1018d
LP
114* per-service credential system. Specifically: add LoadCredential= (for loading
115 cred from file), AcquireCredential= (for asking user for cred, via
116 ask-password), PassCredential= (for passing on credential systemd itself
117 got). Then, place credentials in a per-service, immutable ramfs instance (so
118 that it cannot be swapped out), destroy after use. Also pass via keyring
119 (with graceful fallback to cover for containers). Define CredentialPath= for
120 defining subdir of /run/credentials/ where to place it. Set $CREDENTIAL_PATH
121 env var for services to the result. Also pass via fd passing (optionally).
122
123* homed: add native recovery key support. use 48 lowercase modhex characters
124 (192bit), show qr code of it, include pattern expression in user record.
125
126* homed: introduce "degraded" state for home directories that weren't cleanly
127 unmounted (use xattr we add and remove on the loop back file)
128
129* homed: during login resize fs automatically towards size goal. Specifically,
130 resize to diskSize if possible, but leave a certain amount (configured by a
131 new value diskLeaveFreeSize) of space free on the backing fs.
132
f1eb0ccd
LP
133* homed: permit multiple user record signing keys to be used locally, and pick
134 the right one for signing records automatically depending on a pre-existing
135 signature
1f7c6f90
LP
136
137* homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
138 and insert a local signature instead.
139
15981c26
LP
140* homed: as an extension to the directory+subvolume backend: if located on
141 especially marked fs, then sync down password into LUKS header of that fs,
142 and always verify passwords against it too. Bootstrapping is a problem
15dd4515 143 though: if no one is logged in (or no other user even exists yet), how do you
15981c26
LP
144 unlock the volume in order to create the first user and add the first pw.
145
f1eb0ccd
LP
146* homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
147
c98fef26
LP
148* busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
149 exists and responds.
150
c5ca6d90
LP
151* homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
152 easily?
153
6663cfd5
LP
154* when systemd-nspawn and suchlike dissect an OS image, and there are multiple
155 root partitions, do an strverscmp() on the partition label and boot
156 first. That is inspired how sd-boot figures out which kernel to boot, and
157 thus allows defining OS images which can be A/B updated and we default to the
158 newest version automatically, both in nspawn and in sd-boot
159
97cd52c1 160* cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking
70e9d9a5 161 devices. (see: https://github.com/mjec/fido2-hmac-secret)
97cd52c1 162
d200253b
LP
163* systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
164 creates
165
86b52a39 166* homed/userdb: distinguish passwords and recovery keys in the records, since
006c44c1
LP
167 we probably want to use different PBKDF algorithms/settings for them:
168 passwords have low entropy but recovery keys should have good entropy key
169 hence we can make them quicker to work.
170
492f91d8
LP
171* bootctl:
172 - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation
173 - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host
174 - make it operate on loopback files, dissecting enough to find ESP to operate on
175
e1d32d6e
LP
176* by default, in systemd --user service bump the OOMAdjust to 100, as privs
177 allow so that systemd survives
178
c809ed78
LP
179* cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
180 "base64:" prefix. Useful in particular for pkcs11 mode.
181
56a061f5
LP
182* cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
183 systemd-makefs.service instead.
184
91fc013f 185* socket units: allow creating a udev monitor socket with ListenDevices= or so,
86b52a39 186 with matches, then activate app through that passing socket over
91fc013f 187
cdfd8537
LP
188* unify on openssl (as soon as OpenSSL 3.0 is out, and the Debian license
189 confusion is gone)
492f91d8
LP
190 - port sd_id128_get_machine_app_specific() over from khash
191 - port resolved over from libgcrypt (DNSSEC code)
192 - port journald + fsprg over from libgcrypt
193 - port importd over from libgcrypt
194 - when that's done: kill khash.c
195 - when that's done: kill gnutls support in resolved
196
0e7e8544
LP
197* kill zenata, all hail weblate?
198
492f91d8
LP
199* when we resize disks (homed?) always round up to 4K sectors, not 512K
200
201* add growvol and makevol options for /etc/crypttab, similar to
202 x-systemd.growfs and x-systemd-makefs.
203
204* hook up the TPM to /etc/crypttab, with a new option that is similar to the
205 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
206 unsealed from the TPM. Optionally, if TPM is not available fall back to
207 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
208 that the device paths stay the same, regardless if crypto is used or not.
209
492f91d8 210* systemd-repart: by default generate minimized partition tables (i.e. tables
86b52a39 211 that only cover the space actually used, excluding any free space at the
492f91d8
LP
212 end), in order to maximize dd'ability. Requires libfdisk work, see
213 https://github.com/karelzak/util-linux/issues/907
214
86b52a39 215* systemd-repart: optionally, allow specifying a path to initialize new
492f91d8
LP
216 partitions from, i.e. an fs image file or a source device node. This would
217 then turn systemd-repart into a simple installer: with a few .repart files
006c44c1
LP
218 you could replicate the host system on another device. a full installer would
219 then be: "systemd-repart /dev/sda && bootctl install /dev/sda &&
220 systemd-firstboot --image= …"
492f91d8
LP
221
222* systemd-repart: MBR partition table support. Care needs to be taken regarding
223 Type=, so that partition definitions can sanely apply to both the GPT and the
224 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
225 for the two partition types explicitly. And provide an internal mapping so
226 that "Type=linux-generic" maps to the right types for both partition tables
227 automatically.
228
229* systemd-repart: allow sizing partitions as factor of available RAM, so that
230 we can reasonably size swap partitions for hibernation.
231
006c44c1
LP
232* systemd-repart: allow running mkfs before making partitions pop up +
233 encryption via LUKS to allow booting into an empty root with only /usr mounted in
234
235* systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
236
237* systemd-repart: allow disabling growing of specific partitions, or making
238 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
239
240* systemd-repart: add specifier expansion, add especifier that refers to root
241 device node of current system, /usr device node, and matching verity, so that
242 an installer can be made a "copy" installer of the booted OS
243
2a4be3c5 244* systemd-repart: make it a static checker during early boot for existence and
006c44c1
LP
245 absence of other partitions for trusted boot environments
246
006c44c1
LP
247* systemd-repart: allow config of partition uuid
248
77b19caf
LP
249* userdb: allow username prefix searches in varlink API, allow realname and
250 realname substr searches in varlink API
006c44c1 251
76410e98
LP
252* userdb: allow uid/gid range checks
253
2a4be3c5 254* userdb: allow existence checks
006c44c1 255
f1eb0ccd 256* pid1: activation by journal search expression
006c44c1 257
492f91d8
LP
258* when switching root from initrd to host, set the machine_id env var so that
259 if the host has no machine ID set yet we continue to use the random one the
260 initrd had set.
261
173c7873
LP
262* sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
263 it fo reaping assigned but unknown children. This needs to some special care
264 to operate somewhat sensibly in light of priorities: P_ALL will return
265 arbitrary processes, regardless of the priority we want to watch them with,
266 hence on each event loop iteration check all processes which we shall watch
267 with higher prio explicitly, and then watch the entire rest with P_ALL.
268
269* tweak sd-event's child watching: keep a prioq of children to watch and use
270 waitid() only on the children with the highest priority until one is waitable
271 and ignore all lower-prio ones from that point on
272
173c7873
LP
273* maybe introduce xattrs that can be set on the root dir of the root fs
274 partition that declare the volatility mode to use the image in. Previously I
275 thought marking this via GPT partition flags but that's not ideal since
276 that's outside of the LUKS encryption/verity verification, and we probably
277 shouldn't operate in a volatile mode unless we got told so from a trusted
278 source.
279
173c7873
LP
280* figure out automatic partition discovery when combining writable root dir
281 with immutable /usr
282
97e5cc88
LP
283* coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
284 may be used to mark a whole binary as non-coredumpable. Would fix:
285 https://bugs.freedesktop.org/show_bug.cgi?id=69447
286
f3e361c1
LP
287* teach parse_timestamp() timezones like the calendar spec already knows it
288
9ef3376b
LP
289* beef up hibernation to optionally do swapon/swapoff immediately before/after
290 the hibernation
291
c846b233
LP
292* beef up s2h to implement a battery watch loop: instead of entering
293 hibernation unconditionally after coming back from resume make a decision
294 based on the battery load level: if battery level is above a specific
295 threshold, go to suspend again, only hibernate if below it. This means we'd
296 stick to suspend usually, but fall back to hibernation only when battery runs
297 empty (well, subject to our sampling interval). Related to this, check if we
298 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
299 i.e. see if it can wake up machines from suspend, so that we could resume
300 automatically when the system is low on power and move automatically to
301 hibernation mode. (see
302 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
303 section 10.2.2.8 and
304 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
305 at the end).
306
f293fc51
LP
307* add an explicit "vertical" mode to format-table, so that "systemctl
308 status"-like outputs (i.e. with a series of field names left and values
309 right) become genuine first class citizens, and we gain automatic, sane JSON
310 output for them.
311
f293fc51
LP
312* systemd-firstboot: teach it dissector magic, so that you can point it to some
313 disk image and it will just set everything in it all behind the scenes.
314
9c230b8f
LP
315* We should probably replace /var/log/README, /etc/rc.d/README with symlinks
316 that are linked to these places instead of copied. After all they are
317 constant vendor data.
318
c6526b8d 319* maybe add kernel cmdline params: to force random seed crediting
312dc153
LP
320
321* nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
322 so that we make cgroup agent logic safe
323
324* nspawn/machined: add API to invoke binary in container, then use that as
325 fallback in "machinectl shell"
72bd8525 326
ac5dca64
LP
327* logind: rework pam_logind to also do a bus call in case of invocation from
328 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
329 behaviour selectable via pam module option.
330
c809ed78
LP
331* homed:
332 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
333 - hook up machined/nspawn users with a varlink user query interface
334 - rollback when resize fails mid-operation
335 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
336 - resize on login?
c809ed78
LP
337 - shrink fs on logout?
338 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
339 - create on activate?
340 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
341 - communicate clearly when usb stick is safe to remove. probably involves
342 beefing up logind to make pam session close hook synchronous and wait until
343 systemd --user is shut down.
344 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
345 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk images (think: time machine)
86b52a39 346 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
c809ed78
LP
347 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
348 - fingerprint authentication, pattern authentication, …
349 - make sure "classic" user records can also be managed by homed
350 - description field for groups
351 - make size of $XDG_RUNTIME_DIR configurable in user record
352 - reuse pwquality magic in firstboot
353 - query password from kernel keyring first
354 - update even if record is "absent"
355 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
356 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
357 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
358 - make slice for users configurable (requires logind rework)
359 - logind: populate auto-login list bus property from PKCS#11 token
360 - when determining state of a LUKS home directory, check DM suspended sysfs file
361
ac5dca64
LP
362* introduce a new per-process uuid, similar to the boot id, the machine id, the
363 invocation id, that is derived from process creds, specifically a hashed
364 combination of AT_RANDOM + getpid() + the starttime from
365 /proc/self/status. Then add these ids implicitly when logging. Deriving this
366 uuid from these three things has the benefit that it can be derived easily
367 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
368 exec().
369
370* let's not GC a unit while its ratelimits are still pending
371
5daeeecf
LP
372* when killing due to service watchdog timeout maybe detect whether target
373 process is under ptracing and then log loudly and continue instead.
374
5802d977
LP
375* introduce a new group to own TPM devices
376
377* make rfkill uaccess controllable by default, i.e. steal rule from
378 gnome-bluetooth and friends
379
d84520e9
LP
380* tweak journald context caching. In addition to caching per-process attributes
381 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
382 keyed by cgroup path, and guarded by ctime changes. This should provide us
383 with a nice speed-up on services that have many processes running in the same
384 cgroup.
385
03ccc7f0
LP
386* make MAINPID= message reception checks even stricter: if service uses User=,
387 then check sending UID and ignore message if it doesn't match the user or
388 root.
389
390* maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
391 is issued.
392
db3cea22
LP
393* when importing an fs tree with machined, optionally apply userns-rec-chown
394
395* when importing an fs tree with machined, complain if image is not an OS
396
707b3fbd
LP
397* Maybe introduce a helper safe_exec() or so, which is to execve() which
398 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
399 to 1K implicitly, unless explicitly opted-out.
d7b659ef 400
d238709c 401* rework seccomp/nnp logic that even if User= is used in combination with
d96c081a
LP
402 a seccomp option we don't have to set NNP. For that, change uid first whil
403 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
404
06bd149a
LP
405* add a concept for automatically loading per-unit secrets off disk and
406 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
407 ConfigurationDirectory=.
408
8a7cf157
LP
409* when no locale is configured, default to UEFI's PlatformLang variable
410
d3584ec4 411* bootctl,sd-boot: actually honour the "architecture" key
fe1bff15 412
d96c081a
LP
413* add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
414 usefaultd() and make systemd-analyze check for it.
415
06898123 416* paranoia: whenever we process passwords, call mlock() on the memory
309c6b19 417 first. i.e. look for all places we use free_and_erasep() and
9ae4ef49 418 augment them with mlock(). Also use MADV_DONTDUMP.
06898123 419
32875617
LP
420* Move RestrictAddressFamily= to the new cgroup create socket
421
422* support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
423 patching around
424
76853293
LP
425* maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
426 log.c and sd-journal-send
427
06898123
LP
428* optionally: turn on cgroup delegation for per-session scope units
429
d3aeddb8
LP
430* introduce per-unit (i.e. per-slice, per-service) journal log size limits.
431
42e18088
LP
432* sd-boot: automatically load EFI modules from some drop-in dir, so that people
433 can add in file system drivers and such
434
42e18088
LP
435* sd-boot: optionally, show boot menu when previous default boot item has
436 non-zero "tries done" count
437
8f2eb730
LP
438* introduce an option (or replacement) for "systemctl show" that outputs all
439 properties as JSON, similar to busctl's new JSON output. In contrast to that
440 it should skip the variant type string though.
441
442* augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
443 contains some identifier for the project, which allows us to include
444 clickable links to source files generating these log messages. The identifier
445 could be some abberviated URL prefix or so (taking inspiration from Go
446 imports). For example, for systemd we could use
447 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
448 sufficient to build a link by prefixing "http://" and suffixing the
449 CODE_FILE.
450
8f2eb730
LP
451* Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
452 make clickable links from log messages carrying a MESSAGE_ID, that lead to
453 some explanatory text online.
454
7bd4bcf7
LP
455* maybe extend .path units to expose fanotify() per-mount change events
456
a33ffd15
LP
457* Add a "systemctl list-units --by-slice" mode or so, which rearranges the
458 output of "systemctl list-units" slightly by showing the tree structure of
459 the slices, and the units attached to them.
460
20d4b101
LP
461* the a-posteriori stopping of units bound to units that disappeared logic
462 should be reworked: there should be a queue of units, and we should only
bc130b68 463 enqueue stop jobs from a defer event that processes queue instead of
20d4b101
LP
464 right-away when we find a unit that is bound to one that doesn't exist
465 anymore. (similar to how the stop-unneeded queue has been reworked the same
466 way)
4e8113bb 467
126708fa
LP
468* nspawn: make nspawn suitable for shell pipelines: instead of triggering a
469 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
470 for hangup or ^D before passing on the EOF.
471
bb527e11
LP
472* When reloading configuration PID 1 should reset all its properties to the
473 original defaults before calling parse_config()
474
72d711ef 475* nspawn: greater control over selinux label?
c7db2a9d 476
c633b0a6
LP
477* hibernate/s2h: make this robust and safe to enable in Fedora by default.
478 Specifically:
479
480 1. add resume_offset support to the resume code (i.e. support swap files
481 properly)
e83419d0 482 2. check if swap is on weird storage and refuse if so
46c41478 483 3. add auto-detection of hibernation images
c633b0a6 484
070d0ac9
LP
485* cgroups: use inotify to get notified when somebody else modifies cgroups
486 owned by us, then log a friendly warning.
487
e44924f5
LP
488* beef up log.c with support for stripping ANSI sequences from strings, so that
489 it is OK to include them in log strings. This would be particularly useful so
490 that our log messages could contain clickable links for example for unit
491 files and suchlike we operate on.
070d0ac9 492
8c4c2dfc
LP
493* add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
494
495* add attach --enable and attach --now (for attach+enable+start)
496
497* sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
498 selected user is resolvable in the service even if it ships its own /etc/passwd)
499
5da19043 500* Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
5238e957 501 other doesn't. What a disaster. Probably to exclude it. Also
5da19043
LP
502 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
503 numbers.
504
16270697
LP
505* Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
506 usually IN_ATTRIB is the right way to watch deleted files, as the former only
507 fires when a file is actually removed from disk, i.e. the link count drops to
508 zero and is not open anymore, while the latter happens when a file is
509 unlinked from any dir.
510
bd1b3f75 511* port systemctl, busctl, … over to format-table.[ch]'s table formatters
5da19043 512
7bc756ff
LP
513* pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
514
515* add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
516
53c70a27
LP
517* introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
518 files and directories that are left writable for a unit, and which are
519 removed after the unit goes down again. A bit like --ephemeral for
520 systemd-nspawn but for system services. If used together with RootImage= this
521 should reflink the image file itself.
522
523 Related: add Ephemeral=<path1> <path2> … which would allow marking
524 specific paths only like this.
525
53c70a27 526* add CopyFile= or so as unit file setting that may be used to copy files or
5238e957 527 directory trees from the host to the services RootImage= and RootDirectory=
53c70a27
LP
528 environment. Which we can use for /etc/machine-id and in particular
529 /etc/resolv.conf. Should be smart and do something useful on read-only
530 images, for example fallback to read-only bind mounting the file instead.
531
d9b50610
LP
532* show invocation ID in systemd-run output
533
534* bypass SIGTERM state in unit files if KillSignal is SIGKILL
535
9711b1ad
LP
536* add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
537 and so on, which would mean we could report errors and such.
538
1e784321
LP
539* teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
540 project quota
0d545655 541
6b7b0f39
LP
542* introduce DefaultSlice= or so in system.conf that allows changing where we
543 place our units by default, i.e. change system.slice to something
544 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
545 be moved somewhere else too. Finally machined and logind should get similar
546 options so that it is possible to move user session scopes and machines to a
547 different slice too by default. Usecase: people who want to put resources on
548 the entire system, with the exception of one specific service. See:
549 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
550
aa79f932
LP
551* maybe rework get_user_creds() to query the user database if $SHELL is used
552 for root, but only then.
586a8e93 553
46099c9e
LP
554* be stricter with fds we receive for the fdstore: close them asynchronously
555
46099c9e
LP
556* calenderspec: add support for week numbers and day numbers within a
557 year. This would allow us to define "bi-weekly" triggers safely.
558
c3cd7cc9
LP
559* sd-bus: add vtable flag, that may be used to request client creds implicitly
560 and asynchronously before dispatching the operation
561
06345858
LP
562* make use of ethtool veth peer info in machined, for automatically finding out
563 host-side interface pointing to the container.
564
48f1b5e5
LP
565* add some special mode to LogsDirectory=/StateDirectory=… that allows
566 declaring these directories without necessarily pulling in deps for them, or
567 creating them when starting up. That way, we could declare that
568 systemd-journald writes to /var/log/journal, which could be useful when we
569 doing disk usage calculations and so on.
570
cb77e122 571* taint systemd if there are fewer than 65536 users assigned (userns) to the system.
c6009ff0 572
899feb72 573* deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
c6009ff0 574
3d80d454
LP
575* add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
576 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
577 as the unit is running or has a job queued.
578
5f7ecd61 579* support projid-based quota in machinectl for containers
5962e9db 580
17b6f896
LP
581* add a way to lock down cgroup migration: a boolean, which when set for a unit
582 makes sure the processes in it can never migrate out of it
583
17b6f896
LP
584* blog about fd store and restartable services
585
586* document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
587
370f9c21
LP
588* rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
589 magic meaning and is no longer upgraded to something else if set explicitly.
590
17b6f896
LP
591* in the long run: permit a system with /etc/machine-id linked to /dev/null, to
592 make it lose its identity, i.e. be anonymous. For this we'd have to patch
593 through the whole tree to make all code deal with the case where no machine
594 ID is available.
595
596* optionally, collect cgroup resource data, and store it in per-unit RRD files,
597 suitable for processing with rrdtool. Add bus API to access this data, and
598 possibly implement a CPULoad property based on it.
599
e7e4a258
LP
600* beef up pam_systemd to take unit file settings such as cgroups properties as
601 parameters
602
6fc373ee
LP
603* maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
604 the quota of a the user indicated in User= via unit file settings, like the
5962e9db
LP
605 other resource management concepts. Would mix nicely with DynamicUser=1. Or
606 alternatively, do this with projids, so that we can also cover services
607 running as root. Quota should probably cover all the special dirs such as
608 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
609 is set, plus the whole disk space any image configured with RootImage=.
6fc373ee 610
9a92a97a
LP
611* In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
612 disks to see if the UID is already in use.
613
2368e974
LP
614* add "systemctl wait" or so, which does what "systemd-run --wait" does, but
615 for all units. It should be both a way to pin units into memory as well as a
616 wait to retrieve their exit data.
617
fa991fb7
LP
618* expose IO accounting data on the bus, show it in systemd-run --wait and log
619 about it in the resource log message
620
fa991fb7
LP
621* show whether a service has out-of-date configuration in "systemctl status" by
622 using mtime data of ConfigurationDirectory=.
623
d73b607d
LP
624* Add AddUser= setting to unit files, similar to DynamicUser=1 which however
625 creates a static, persistent user rather than a dynamic, transient user. We
626 can leverage code from sysusers.d for this.
627
fd63f36c
LP
628* add some optional flag to ReadWritePaths= and friends, that has the effect
629 that we create the dir in question when the service is started. Example:
630
631 ReadWritePaths=:/var/lib/foobar
632
3576dddf
LP
633* maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
634 the sd-journal logging socket, and, if the timeout is set to 0, sets
635 O_NONBLOCK on it. That way people can control if and when to block for
636 logging.
637
fe6a0235
LP
638* hostnamed: populate form factor data from a new hwdb database, so that old
639 yogas can be recognized as "convertible" too, even if they predate the DMI
640 "convertible" form factor
641
d543b9f5
LP
642* Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
643 after all. Be strict however, only support the equivalent of nspawn's
644 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
645 as MAINPID.
646
f59d1da8
LP
647* Add ExecMonitor= setting. May be used multiple times. Forks off a process in
648 the service cgroup, which is supposed to monitor the service, and when it
649 exits the service is considered failed by its monitor.
650
33bac67b
LP
651* track the per-service PAM process properly (i.e. as an additional control
652 process), so that it may be queried on the bus and everything.
653
654* add a new "debug" job mode, that is propagated to unit_start() and for
655 services results in two things: we raise SIGSTOP right before invoking
656 execve() and turn off watchdog support. Then, use that to implement
657 "systemd-gdb" for attaching to the start-up of any system service in its
658 natural habitat.
659
8eb7383b
LP
660* gpt-auto logic: related to the above, maybe support a "secondary" root
661 partition, that is mounted to / and is writable, and where the actual root's
662 /usr is mounted into.
663
8eb7383b
LP
664* 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
665
67234d21
LP
666* drop nss-myhostname in favour of nss-resolve?
667
b5bdbcd5
LP
668* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
669 then use that for the setting used in user@.service. It should be understood
670 relative to the configured default value.
671
d21494ea
LP
672* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
673
674* enable LockMLOCK to take a percentage value relative to physical memory
675
04397464 676* Permit masking specific netlink APIs with RestrictAddressFamily=
d82047be 677
d82047be
LP
678* nspawn: support that /proc, /sys/, /dev are pre-mounted
679
d82047be
LP
680* define gpt header bits to select volatility mode
681
42d61ded
LP
682* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
683
04397464 684* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
42d61ded 685
04397464 686* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
563a69f4 687
04397464 688* ProtectKeyRing= to take keyring calls away
2c5f2958 689
8ce9b83a 690* RemoveKeyRing= to remove all keyring entries of the specified user
a46eac1b
LP
691
692* ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
693 on PID 1 with the relevant signals, and makes relevant files in /sys and
694 /proc (such as the sysrq stuff) unavailable
695
e40a326c 696* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
89f193fa 697
6809de5b
LP
698* journalctl: make sure -f ends when the container indicated by -M terminates
699
2c5f2958
LP
700* mount: automatically search for "main" partition of an image has multiple
701 partitions
702
8ce9b83a
LP
703* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
704 find a way to map the User=/Group= of the service to the right name. This way
705 a user/group for a service only has to exist on the host for the right
706 mapping to work.
707
2c5f2958
LP
708* add bus API for creating unit files in /etc, reusing the code for transient units
709
710* add bus API to remove unit files from /etc
711
712* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
713
b8c7afdf
LP
714* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
715 kernel doesn't support linkat() that replaces existing files, currently)
716
1e555cb5
LP
717* transient units: don't bother with actually setting unit properties, we
718 reload the unit file anyway
719
1e555cb5
LP
720* journald: sigbus API via a signal-handler safe function that people may call
721 from the SIGBUS handler
722
c8048350
LP
723* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
724
648b1220
LP
725* delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
726 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
727
3d39e6e5
LP
728* cache sd_event_now() result from before the first iteration...
729
bd098bce
LP
730* PID1: find a way how we can reload unit file configuration for
731 specific units only, without reloading the whole of systemd
732
f9bf1b8f 733* add an explicit parser for LimitRTPRIO= that verifies
de7399eb 734 the specified range and generates sane error messages for incorrect
f9bf1b8f 735 specifications.
de7399eb 736
3efc8c72
LP
737* when we detect that there are waiting jobs but no running jobs, do something
738
5ebbb45b 739* push CPUAffinity= also into the "cpuset" cgroup controller
03364e47 740
e6a26d8c
LP
741* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
742
a2088fd0 743* there's probably something wrong with having user mounts below /sys,
5238e957 744 as we have for debugfs. for example, src/core/mount.c handles mounts
a2088fd0
LP
745 prefixed with /sys generally special.
746 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
747
8aa20381
LP
748* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
749
b18d23d7
LP
750* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
751
60d17b74
LP
752* add a job mode that will fail if a transaction would mean stopping
753 running units. Use this in timedated to manage the NTP service
754 state.
755 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
756
477e75ef
LP
757* The udev blkid built-in should expose a property that reflects
758 whether media was sensed in USB CF/SD card readers. This should then
759 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
760 picked up by systemd unless they contain a medium. This would mirror
761 the behaviour we already have for CD drives.
762
2bc39683
LP
763* networkd/udev: implement SR_IOV configuration in .link files:
764 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
765
c3a0d00d
LP
766* hostnamectl: show root image uuid
767
d2f81fb0
LP
768* Find a solution for SMACK capabilities stuff:
769 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
98cd2651 770
2a441c8a
LP
771* "systemctl preset-all" should probably order the unit files it
772 operates on lexicographically before starting to work, in order to
773 ensure deterministic behaviour if two unit files conflict (like DMs
774 do, for example)
775
0a86c1a9
LP
776* synchronize console access with BSD locks:
777 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
778
e031c227 779* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
0a86c1a9
LP
780 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
781
8514b677
LP
782* figure out when we can use the coarse timers
783
7b0fce61
LP
784* add "systemctl start -v foobar.service" that shows logs of a service
785 while the start command runs. This is non-trivial to do without
786 races though, since we should flush out all journal messages before
787 returning from the "systemctl stop".
788
b568ef14 789* 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
c2d5b3c9 790
d48b7bd2
LP
791* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
792
8483d73f
LP
793* maybe allow timer units with an empty Units= setting, so that they
794 can be used for resuming the system but nothing else.
795
25e773ee 796* what to do about udev db binary stability for apps? (raw access is not an option)
b857e042 797
279f0366 798* systemctl: if some operation fails, show log output?
533bb267 799
5238e957 800* systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
b42de08a 801 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
202aea45 802
720652b3 803* exponential backoff in timesyncd when we cannot reach a server
42aeb14a 804
720652b3 805* timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
e25b5a8d 806
563b1bdc
LP
807* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
808
6bd7941e
TG
809* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
810 (throughout the codebase, not only PID1)
811
9d6db739 812* resolved:
9d6db739 813 - mDNS/DNS-SD
ccc3e8a1
LP
814 - service registration
815 - service/domain/types browsing
0f47ed0a 816 - avahi compat
9d6db739 817 - DNS-SD service registration from socket units
e25b5a8d
DH
818 - resolved should optionally register additional per-interface LLMNR
819 names, so that for the container case we can establish the same name
820 (maybe "host") for referencing the server, everywhere.
720652b3 821 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
3efb871a 822 - hook up resolved with machined-based address resolution
3f77a1b1 823
e25b5a8d 824* refcounting in sd-resolve is borked
e2a69298 825
2834ffe7

827
a940778f
LP
828* add new gpt type for btrfs volumes
829
a01647e5 830* support empty /etc boots nicely:
3c779fa5 831 - nspawn/gpt-generator: introduce new gpt partition type for /usr
a01647e5 832
3de03738
LP
833* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
834
37efac5d
LP
835* a way for container managers to turn off getty starting via $container_headless= or so...
836
7348b3ad
LP
837* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
838
81429136
KS
839* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
840 they run added to the initial transaction and thus confuse Type=idle.
e107ed18 841
edb2935c
LP
842* add bus api to query unit file's X fields.
843
6a3f892a 844* gpt-auto-generator:
2a781fc9 845 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
6a3f892a 846 - Make /home automount rather than mount?
6a3f892a 847
65026403
LP
848* add generator that pulls in systemd-network from containers when
849 CAP_NET_ADMIN is set, more than the loopback device is defined, even
850 when it is otherwise off
f8901862 851
f9bf1b8f 852* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
eda8f067 853
af1082b0
LP
854* implement Distribute= in socket units to allow running multiple
855 service instances processing the listening socket, and open this up
856 for ReusePort=
857
09ecd746
LP
858* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
859 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
860 should SIGSTOP all unit processes in a loop until all processes of
861 it are fully stopped. This can later be used for app management by
862 desktop UIs such as gnome-shell to freeze apps that are not visible
863 on screen, not unlike how job control works on the shell
864
f38afcd0 865* cgroups:
f38afcd0 866 - implement per-slice CPUFairScheduling=1 switch
f38afcd0
LP
867 - introduce high-level settings for RT budget, swappiness
868 - how to reset dynamically changed unit cgroup attributes sanely?
869 - when reloading configuration, apply new cgroup configuration
870 - when recursively showing the cgroup hierarchy, optionally also show
871 the hierarchies of child processes
0bee65f0 872
f38afcd0 873* transient units:
f38afcd0 874 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
ebcf1f97 875
718db961
LP
876* when we detect low battery and no AC on boot, show pretty splash and refuse boot
877
718db961
LP
878* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
879
966204e0
LP
880* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
881
41644622
LP
882* 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
883
7f79cd71 884* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
0aafd43d 885
19aadacf
JE
886* If we try to find a unit via a dangling symlink, generate a clean
887 error. Currently, we just ignore it and read the unit from the search
df5f6971
LP
888 path anyway.
889
04397464 890* refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
fcba531e 891
bdeeb6b5
LP
892* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
893
894* load .d/*.conf dropins for device units
895
6bb648a1 896* sd-bus:
0d43ffef 897 - EBADSLT handling
fa607802 898 - GetAllProperties() on a non-existing object does not result in a failure currently
7212c608 899 - port to sd-resolve for connecting to TCP dbus servers
57f2a947 900 - 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
f38afcd0 901 - see if we can drop more message validation on the sending side
f38afcd0 902 - add API to clone sd_bus_message objects
ab9716c2 903 - longer term: priority inheritance
df98a87b 904 - dbus spec updates:
df98a87b
LP
905 - NameLost/NameAcquired obsolete
906 - GVariant
2ecfc64e 907 - path escaping
6a8b5fa4 908 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
f38afcd0
LP
909
910* sd-event
12179984 911 - allow multiple signal handlers per signal?
0536ce5d 912 - document chaining of signal handler for SIGCHLD and child handlers
e25b5a8d 913 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
eb01ba5d 914
69af4503 915* investigate endianness issues of UUID vs. GUID
e8a7a315 916
461bd8e4
LP
917* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
918 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
919
ab8e074c
LP
920* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
921
922* add a pam module that on password changes updates any LUKS slot where the password matches
923
fff87a35 924* test/:
20d52ab6 925 - add unit tests for config_parse_device_allow()
b8b4d3dd 926
b5c03638 927* seems that when we follow symlinks to units we prefer the symlink
d28315e4 928 destination path over /etc and /usr. We should not do that. Instead
b5c03638
LP
929 /etc should always override /run+/usr and also any symlink
930 destination.
931
eece8c6f
LP
932* when isolating, try to figure out a way how we implicitly can order
933 all units we stop before the isolating unit...
934
356ce991
LP
935* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
936
6daebf9e
ZJS
937* Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
938 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
939 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
940
c1446921
LP
941* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
942 that the boot loader should be installed to the ESP. Define a way
943 how an installer can figure out whether a BLS compliant boot loader
944 is installed.
795607b2 945
0be8342c
LP
946* think about requeuing jobs when daemon-reload is issued? usecase:
947 the initrd issues a reload after fstab from the host is accessible
948 and we might want to requeue the mounts local-fs acquired through
949 that automatically.
950
e5ec62c5 951* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
54c31a79 952
ccddd104 953* remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
826872b6 954
3679d112
LP
955* shutdown logging: store to EFI var, and store to USB stick?
956
356ce991 957* merge unit_kill_common() and unit_kill_context()
490b7e47 958
b44be3ec 959* EFI:
b44be3ec
LP
960 - honor language efi variables for default language selection (if there are any?)
961 - honor timezone efi variables for default timezone selection (if there are any?)
466784c8 962 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
631427d6 963* bootctl
631427d6 964 - recognize the case when not booted on EFI
e4181484 965
c0fe5db5 966* maybe do not install getty@tty1.service symlink in /etc but in /usr?
e9fd44b7 967
b44be3ec 968* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
8ed20651 969
b44be3ec 970* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
e6c6e7af 971
b44be3ec
LP
972* logind:
973 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
b44be3ec
LP
974 - logind: wakelock/opportunistic suspend support
975 - Add pretty name for seats in logind
976 - logind: allow showing logout dialog from system?
f38afcd0
LP
977 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
978 - if pam_systemd is invoked by su from a process that is outside of a
979 any session we should probably just become a NOP, since that's
980 usually not a real user session but just some system code that just
981 needs setuid().
279f0366
LP
982 - logind: make the Suspend()/Hibernate() bus calls wait for the for
983 the job to be completed. before returning, so that clients can wait
984 for "systemctl suspend" to finish to know when the suspending is
985 complete.
986 - logind: when the power button is pressed short, just popup a
987 logout dialog. If it is pressed for 1s, do the usual
988 shutdown. Inspiration are Macs here.
279f0366 989 - expose "Locked" property on logind sesison objects
e25b5a8d
DH
990 - maybe allow configuration of the StopTimeout for session scopes
991 - rename session scope so that it includes the UID. THat way
992 the session scope can be arranged freely in slices and we don't have
993 make assumptions about their slice anymore.
994 - follow PropertiesChanged state more closely, to deal with quick logouts and
995 relogins
77b19caf 996 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
e673ad04 997
b44be3ec 998* journal:
57f2a947 999 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
b44be3ec
LP
1000 - journald: also get thread ID from client, plus thread name
1001 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
1002 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
d28315e4 1003 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
b44be3ec 1004 - declare the local journal protocol stable in the wiki interface chart
b44be3ec
LP
1005 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
1006 - journald: when dropping msgs due to ratelimit make sure to write
1007 "dropped %u messages" not only when we are about to print the next
5238e957 1008 message that works, but already after a short timeout
b44be3ec
LP
1009 - check if we can make journalctl by default use --follow mode inside of less if called without args?
1010 - maybe add API to send pairs of iovecs via sd_journal_send
f47ec8eb 1011 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
b44be3ec
LP
1012 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
1013 and !FOOBAR for events without FOOBAR.
038cf334
ZJS
1014 - journal: store timestamp of journal_file_set_offline() int he header,
1015 so it is possible to display when the file was last synced.
b44be3ec
LP
1016 - 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.
1017 - journal: find a way to allow dropping history early, based on priority, other rules
1018 - journal: When used on NFS, check payload hashes
b44be3ec
LP
1019 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
1020 - refuse taking lower-case variable names in sd_journal_send() and friends.
1021 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
1022 - journal: deal nicely with byte-by-byte copied files, especially regards header
b44be3ec 1023 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
601d9d6f 1024 - Replace utmp, wtmp, btmp, and lastlog completely with journal
f38afcd0 1025 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
f38afcd0
LP
1026 - when a kernel driver logs in a tight loop, we should ratelimit that too.
1027 - journald: optionally, log debug messages to /run but everything else to /var
1028 - journald: when we drop syslog messages because the syslog socket is
1029 full, make sure to write how many messages are lost as first thing
1030 to syslog when it works again.
279f0366
LP
1031 - journald: allow per-priority and per-service retention times when rotating/vacuuming
1032 - journald: make use of uid-range.h to managed uid ranges to split
1033 journals in.
1034 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
1035 - improve journalctl performance by loading journal files
1036 lazily. Encode just enough information in the file name, so that we
1037 do not have to open it to know that it is not interesting for us, for
1038 the most common operations.
e25b5a8d 1039 - man: document that corrupted journal files is nothing to act on
e25b5a8d
DH
1040 - rework journald sigbus stuff to use mutex
1041 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
1042 services that run under their own user ids, and use User= (but only
1043 in a world where userns is ubiquitous since otherwise we cannot
1044 invoke those daemons on the host AND in a container anymore). Also,
1045 if LimitNPROC= is used without User= we should warn and refuse
1046 operation.
1047 - journalctl --verify: don't show files that are currently being
1048 written to as FAIL, but instead show that their are being written to.
1049 - add journalctl -H that talks via ssh to a remote peer and passes through
1050 binary logs data
e25b5a8d 1051 - add a version of --merge which also merges /var/log/journal/remote
e25b5a8d
DH
1052 - journalctl: -m should access container journals directly by enumerating
1053 them via machined, and also watch containers coming and going.
1054 Benefit: nspawn --ephemeral would start working nicely with the journal.
1055 - assign MESSAGE_ID to log messages about failed services
b44be3ec 1056
590171d1
ZJS
1057* add a test if all entries in the catalog are properly formatted.
1058 (Adding dashes in a catalog entry currently results in the catalog entry
1059 being silently skipped. journalctl --update-catalog must warn about this,
1060 and we should also have a unit test to check that all our message are OK.)
1061
b44be3ec 1062* document:
8b8f2591 1063 - document that deps in [Unit] sections ignore Alias= fields in
b44be3ec
LP
1064 [Install] units of other units, unless those units are disabled
1065 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
b44be3ec 1066 - document that service reload may be implemented as service reexec
f38afcd0
LP
1067 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1068 - document systemd-journal-flush.service properly
f38afcd0
LP
1069 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1070 - man: document the very specific env the shutdown drop-in tools live in
f38afcd0
LP
1071 - man: add more examples to man pages
1072 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
17ec531f 1073 - document root=gpt-auto properly
b44be3ec
LP
1074
1075* systemctl:
b44be3ec
LP
1076 - add systemctl switch to dump transaction without executing it
1077 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1078 - "systemctl disable" on a static unit prints no message and does
1079 nothing. "systemctl enable" does nothing, and gives a bad message
1080 about it. Should fix both to print nice actionable messages.
1081 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1082 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
d28315e4 1083 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
b44be3ec 1084 - systemctl: "Journal has been rotated since unit was started." message is misleading
61233823 1085 - systemctl status output should include list of triggering units and their status
f38afcd0
LP
1086
1087* unit install:
1088 - "systemctl mask" should find all names by which a unit is accessible
1089 (i.e. by scanning for symlinks to it) and link them all to /dev/null
8b04b925 1090
b44be3ec 1091* timer units:
b44be3ec 1092 - timer units should get the ability to trigger when:
b44be3ec 1093 o DST changes
90e071d1 1094 - Modulate timer frequency based on battery state
d2e83c23 1095
a19554ed
LP
1096* add libsystemd-password or so to query passwords during boot using the password agent logic
1097
a7a3f28b
LP
1098* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1099
b44be3ec 1100* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
08f95888 1101
f59d1da8 1102* make repeated alt-ctrl-del presses printing a dump
dcfc4b2e 1103
71ef24d0
LP
1104* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1105
d28315e4 1106* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
1b89884b 1107
b44be3ec 1108* nspawn:
e25b5a8d
DH
1109 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1110 with seccomp. That should provide us with a useful log buffer that
1111 systemd can log to during early boot, and disconnect container logs
1112 from the kernel's logs.
1113 - as soon as networkd has a bus interface, hook up --network-interface=,
1114 --network-bridge= with networkd, to trigger netdev creation should an
1115 interface be missing
e25b5a8d
DH
1116 - a nice way to boot up without machine id set, so that it is set at boot
1117 automatically for supporting --ephemeral. Maybe hash the host machine id
1118 together with the machine name to generate the machine id for the container
1119 - fix logic always print a final newline on output.
1120 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1121 - should optionally support receiving WATCHDOG=1 messages from its payload
1122 PID 1...
e25b5a8d
DH
1123 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1124 running, remove them when shut down.
e25b5a8d 1125
347a17d5
ZJS
1126* dissect
1127 - refuse mounting over a mount point
1128 - automatically discover .roothash files in dissect, similarly to nspawn
1129
e25b5a8d 1130* machined:
e25b5a8d
DH
1131 - add an API so that libvirt-lxc can inform us about network interfaces being
1132 removed or added to an existing machine
1133 - "machinectl migrate" or similar to copy a container from or to a
1134 difference host, via ssh
e25b5a8d
DH
1135 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1136 "machinectl start" with a new --ephemeral switch
1137 - "machinectl status" should also show internal logs of the container in
1138 question
e25b5a8d
DH
1139 - "machinectl history"
1140 - "machinectl diff"
1141 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1142 shell in it, and marks it read-only after use
1143
b44be3ec 1144* cryptsetup:
b44be3ec 1145 - cryptsetup-generator: allow specification of passwords in crypttab itself
5f1dac6b 1146 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
f8019684 1147
424a19f8 1148* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it

LP
1157* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1158
abd55b16 1159* udev:
abd55b16 1160 - move to LGPL
abd55b16
KS

1165* There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1166
d0e5a333
LP
1167* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/

e25b5a8d
DH
1169* coredump:
1170 - save coredump in Windows/Mozilla minidump format
73a99163 1171 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps

KS
1175* be able to specify a forced restart of service A where service B depends on, in case B
1176 needs to be auto-respawned?
1177
f38afcd0 1178* tmpfiles:
f38afcd0 1179 - apply "x" on "D" too (see patch from William Douglas)
614cc34f 1180 - instead of ignoring unknown fields, reject them.
e25b5a8d
DH
1181 - creating new directories/subvolumes/fifos/device nodes
1182 should not follow symlinks. None of the other adjustment or creation
1183 calls follow symlinks.
1258097c 1184
a4c279f8
LP
1185* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1186
f28f1daf
LP
1187* verify that the AF_UNIX sockets of a service in the fs still exist
1188 when we start a service in order to avoid confusion when a user
1189 assumes starting a service is enough to make it accessible
1190
88a07670
LP
1191* Make it possible to set the keymap independently from the font on
1192 the kernel cmdline. Right now setting one resets also the other.

1216
59fee421
LP
1217* dot output for --test showing the 'initial transaction'
1218
e25b5a8d 1219* pid1:
e25b5a8d
DH
1220 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1221 log both units as UNIT=, so that journalctl -u triggers on both.
1222 - generate better errors when people try to set transient properties
1223 that are not supported...
1224 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1225 - maybe introduce WantsMountsFor=? Usecase:
1226 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1227 - recreate systemd's D-Bus private socket file on SIGUSR2
e25b5a8d
DH
1228 - move PAM code into its own binary
1229 - when we automatically restart a service, ensure we restart its rdeps, too.
e25b5a8d
DH
1230 - hide PAM options in fragment parser when compile time disabled
1231 - Support --test based on current system state
1232 - 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().
1233 - after deserializing sockets in socket.c we should reapply sockopts and things
e25b5a8d
DH
1234 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1235 currently is properly synchronous, Reexec() is weird, because we
1236 cannot delay the response properly until we are back, so instead of
1237 being properly synchronous we just keep open the fd and close it
1238 when done. That means clients do not get a successful method reply,
1239 but much rather a disconnect on success.
1240 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1241 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1242
1243* unit files:
1244 - allow port=0 in .socket units
1245 - maybe introduce ExecRestartPre=
1246 - add ReloadSignal= for configuring a reload signal to use
1247 - implement Register= switch in .socket units to enable registration
1248 in Avahi, RPC and other socket registration services.
1249 - allow Type=simple with PIDFile=
1250 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1251 - allow writing multiple conditions in unit files on one line
e25b5a8d 1252 - introduce Type=pid-file
e25b5a8d
DH
1253 - introduce mix of BindTo and Requisite
1254 - add a concept of RemainAfterExit= to scope units
e25b5a8d 1255 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
e5171296 1256 - add verification of [Install] section to systemd-analyze verify
e25b5a8d 1257
af6f0d42
TG
1258* udev-link-config:
1259 - Make sure ID_PATH is always exported and complete for
1260 network devices where possible, so we can safely rely
1261 on Path= matching
af6f0d42 1262
88e4d1d7 1263* sd-rtnl:
88e4d1d7 1264 - add support for more attribute types

88e4d1d7 1266
0a4b9a07 1267* networkd:
c74ecd71
TG
1268 - add more keys to [Route] and [Address] sections
1269 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
e8d842a0 1270 - add reduced [Link] support to .network files
798e174a 1271 - properly handle routerless dhcp leases
a8eaaee7 1272 - work with non-Ethernet devices
e25b5a8d 1273 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
e25b5a8d
DH
1274 - the DHCP lease data (such as NTP/DNS) is still made available when
1275 a carrier is lost on a link. It should be removed instantly.
1276 - expose in the API the following bits:
e2da6491 1277 - option 15, domain name
38b38500 1278 - option 12, hostname and/or option 81, fqdn
e25b5a8d
DH
1279 - option 123, 144, geolocation
1280 - option 252, configure http proxy (PAC/wpad)
1281 - provide a way to define a per-network interface default metric value
1282 for all routes to it. possibly a second default for DHCP routes.
1283 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1284 support Name=foo*|bar*|baz ?
1285 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
e25b5a8d 1286 - whenever uplink info changes, make DHCP server send out FORCERENEW

37d8b536
PF
1293* dhcp6:
1294 - add functions to set previously stored IPv6 addresses on startup and get
1295 them at shutdown; store them in client->ia_na
1296 - write more test cases
37d8b536 1297 - implement reconfigure support, see 5.3., 15.11. and 22.20.
37d8b536 1298 - implement support for temporary adressess (IA_TA)
37d8b536
PF
1299 - implement dhcpv6 authentication
1300 - investigate the usefulness of Confirm messages; i.e. are there any
1301 situations where the link changes without any loss in carrier detection
1302 or interface down
1303 - some servers don't do rapid commit without a filled in IA_NA, verify
1304 this behavior
4a77c53d 1305 - RouteTable= ?
