Lennart Poetteringafe3ab52014-10-24 19:07:01 +02001Bugfixes:
Kay Sieversc343be22014-06-04 11:14:48 +02002
Zbigniew Jędrzejewski-Szmek54fcb612018-10-16 13:28:39 +02003* 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.

Lennart Poetteringf85857d2014-10-29 17:08:00 +01008
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01009* Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
Lennart Poetteringbafb15b2013-07-11 00:28:35 +020010
Lennart Poettering5e524b42015-10-26 22:02:13 +010011Janitorial Clean-ups:
12
Lennart Poettering5e524b42015-10-26 22:02:13 +010013* Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again
14
Lennart Poetteringbb527e12018-06-04 21:00:44 +020015* rework mount.c and swap.c to follow proper state enumeration/deserialization
16 semantics, like we do for device.c now
17
Lennart Poetteringc6407102018-06-07 17:35:58 +020018Features:
19
Lennart Poettering4c150802020-06-10 18:37:00 +020020* add --copy-from and --copy-to command to systemd-dissect which copies stuff
21 in and out of a disk image
22
Lennart Poettering707dc792020-06-09 08:54:41 +020023* 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
Lennart Poetteringeffefa32020-05-26 14:46:35 +020031* if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it
32
Lennart Poetteringe78228b2020-06-26 15:43:24 +020033* 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
Lennart Poettering6ae8c6f2020-05-26 09:21:40 +020037* 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
Lennart Poetteringd08a6ec2020-05-19 19:58:26 +020040* 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
Lennart Poettering5c0102f2020-06-02 10:39:19 +020046* 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
Lennart Poettering34d16ba2020-05-18 18:29:38 +020050* 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
Lennart Poettering3d9237d2020-05-11 23:12:56 +020054* move our systemd-user PAM snippet to /usr/, which PAM appears to support
55 these days
56
Lennart Poetteringf1eb0cc2020-05-10 10:19:05 +020057* nspawn: support time namespaces
58
Lennart Poettering2d2d7502020-05-26 19:05:54 +020059* add ConditionSecurity=tpm2
60
Lennart Poettering42ba8d22020-05-29 18:32:28 +020061* Remove any support for booting without /usr pre-mounted in the initrd entirely.
62 Update INITRD_INTERFACE.md accordingly.
63
Lennart Poetteringf1eb0cc2020-05-10 10:19:05 +020064* pid1: Move to tracking of main pid/control pid of units per pidfd
65
66* pid1: support new clone3() fork-into-cgroup feature
67
Lennart Poettering7cc8fb32020-05-12 20:14:08 +020068* pid1: also remove PID files of a service when the service starts, not just
69 when it exits
70
Lennart Poetteringcdfd8532020-06-16 14:38:23 +020071* 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
Lennart Poettering77169ed2020-06-16 11:42:16 +020088* 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
Lennart Poetteringbfafec22020-05-28 09:38:00 +020096* systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
97 mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
98
Lennart Poettering7cc8fb32020-05-12 20:14:08 +020099* 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
Lennart Poetteringa6e10182020-05-07 23:30:06 +0200103* 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
Lennart Poettering112bed82020-06-02 14:56:08 +0200107* 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
Lennart Poetteringa6e10182020-05-07 23:30:06 +0200114* 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
Lennart Poetteringf1eb0cc2020-05-10 10:19:05 +0200133* 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
Lennart Poettering1f7c6f92020-05-05 19:36:21 +0200136
137* homed: add a way to "adopt" a home directory, i.e. strip foreign signatures
138 and insert a local signature instead.
139
Lennart Poettering15981c22020-05-09 10:37:32 +0200140* 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
Frantisek Sumsal15dd4512020-05-24 23:00:13 +0200143 though: if no one is logged in (or no other user even exists yet), how do you
Lennart Poettering15981c22020-05-09 10:37:32 +0200144 unlock the volume in order to create the first user and add the first pw.
145
Lennart Poetteringf1eb0cc2020-05-10 10:19:05 +0200146* homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt
147
Lennart Poetteringc98fef22020-04-28 19:38:38 +0200148* busctl: maybe expose a verb "ping" for pinging a dbus service to see if it
149 exists and responds.
150
Lennart Poetteringc5ca6d92020-04-21 21:23:01 +0200151* homed: maybe pre-create ~/.cache as subvol so that it can have separate quota
152 easily?
153
Lennart Poettering6663cfd2020-04-13 14:31:46 +0200154* 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
Lennart Poettering97cd52c2020-01-29 19:22:26 +0100160* cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking
Lennart Poettering70e9d9a2020-01-29 19:32:39 +0100161 devices. (see: https://github.com/mjec/fido2-hmac-secret)
Lennart Poettering97cd52c2020-01-29 19:22:26 +0100162
Lennart Poetteringd2002532020-01-29 16:55:59 +0100163* systemd-gpt-auto should probably set x-systemd.growfs on the mounts it
164 creates
165
Frantisek Sumsal86b52a32020-04-21 20:46:53 +0200166* homed/userdb: distinguish passwords and recovery keys in the records, since
Lennart Poettering006c44c2020-01-28 15:04:49 +0100167 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
Lennart Poettering492f91d2019-12-10 23:47:06 +0100171* 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
Lennart Poetteringb47261e2020-06-26 18:04:52 +0200176* Maybe add a separate GPT partition type to the discoverable partition spec
177 for "hibernate" partitions, that are exactly like swap partitions but only
178 activated right before hibernation and thus never used for regular swapping.
179
Lennart Poetteringe1d32d62020-01-23 22:59:47 +0100180* by default, in systemd --user service bump the OOMAdjust to 100, as privs
181 allow so that systemd survives
182
Lennart Poetteringc809ed72019-07-04 18:16:30 +0200183* cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a
184 "base64:" prefix. Useful in particular for pkcs11 mode.
185
Lennart Poettering56a061f2019-12-19 16:43:39 +0100186* cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use
187 systemd-makefs.service instead.
188
Lennart Poettering91fc0132019-11-12 15:18:37 +0100189* socket units: allow creating a udev monitor socket with ListenDevices= or so,
Frantisek Sumsal86b52a32020-04-21 20:46:53 +0200190 with matches, then activate app through that passing socket over
Lennart Poettering91fc0132019-11-12 15:18:37 +0100191
Lennart Poetteringcdfd8532020-06-16 14:38:23 +0200192* unify on openssl (as soon as OpenSSL 3.0 is out, and the Debian license
193 confusion is gone)
Lennart Poettering492f91d2019-12-10 23:47:06 +0100194 - port sd_id128_get_machine_app_specific() over from khash
195 - port resolved over from libgcrypt (DNSSEC code)
196 - port journald + fsprg over from libgcrypt
197 - port importd over from libgcrypt
198 - when that's done: kill khash.c
199 - when that's done: kill gnutls support in resolved
200
Lennart Poettering0e7e8542019-11-29 17:31:03 +0100201* kill zenata, all hail weblate?
202
Lennart Poettering492f91d2019-12-10 23:47:06 +0100203* when we resize disks (homed?) always round up to 4K sectors, not 512K
204
205* add growvol and makevol options for /etc/crypttab, similar to
206 x-systemd.growfs and x-systemd-makefs.
207
208* hook up the TPM to /etc/crypttab, with a new option that is similar to the
209 new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key
210 unsealed from the TPM. Optionally, if TPM is not available fall back to
211 TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so
212 that the device paths stay the same, regardless if crypto is used or not.
213
Lennart Poettering492f91d2019-12-10 23:47:06 +0100214* systemd-repart: by default generate minimized partition tables (i.e. tables
Frantisek Sumsal86b52a32020-04-21 20:46:53 +0200215 that only cover the space actually used, excluding any free space at the
Lennart Poettering492f91d2019-12-10 23:47:06 +0100216 end), in order to maximize dd'ability. Requires libfdisk work, see
217 https://github.com/karelzak/util-linux/issues/907
218
Frantisek Sumsal86b52a32020-04-21 20:46:53 +0200219* systemd-repart: optionally, allow specifying a path to initialize new
Lennart Poettering492f91d2019-12-10 23:47:06 +0100220 partitions from, i.e. an fs image file or a source device node. This would
221 then turn systemd-repart into a simple installer: with a few .repart files
Lennart Poettering006c44c2020-01-28 15:04:49 +0100222 you could replicate the host system on another device. a full installer would
223 then be: "systemd-repart /dev/sda && bootctl install /dev/sda &&
224 systemd-firstboot --image= …"
Lennart Poettering492f91d2019-12-10 23:47:06 +0100225
226* systemd-repart: MBR partition table support. Care needs to be taken regarding
227 Type=, so that partition definitions can sanely apply to both the GPT and the
228 MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types
229 for the two partition types explicitly. And provide an internal mapping so
230 that "Type=linux-generic" maps to the right types for both partition tables
231 automatically.
232
233* systemd-repart: allow sizing partitions as factor of available RAM, so that
234 we can reasonably size swap partitions for hibernation.
235
Lennart Poettering006c44c2020-01-28 15:04:49 +0100236* systemd-repart: allow running mkfs before making partitions pop up +
237 encryption via LUKS to allow booting into an empty root with only /usr mounted in
238
239* systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag
240
Lennart Poetteringb47261e2020-06-26 18:04:52 +0200241* systemd-repart: allow boolean option that ensures that if existing partition
242 doesn't exist within the configured size bounds the whole command fails. This
243 is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set
244 of repart files for the case where ESP is large enough and one where it isn't
245 and XBOOTLDR is added in instead. Then apply the former first, and if it
246 fails to apply use the latter.
247
248* systemd-repart: add per-partition option to never reuse existing partition
249 and always create anew even if matching partition already exists.
250
251* systemd-repart: add per-partition option to fail if partition already exist,
252 i.e. is not added new. Similar, add option to fail if partition does not exist yet.
253
254* systemd-repart: add --size=auto for generating/resizing images of minimal
255 size, i.e. where the image file is sized exactly as large as necessary taking
256 SizeMin= into account, but not a single byte larger.
257
Lennart Poettering006c44c2020-01-28 15:04:49 +0100258* systemd-repart: allow disabling growing of specific partitions, or making
259 them (think ESP: we don't ever want to grow it, since we cannot resize vfat)
260
261* systemd-repart: add specifier expansion, add especifier that refers to root
262 device node of current system, /usr device node, and matching verity, so that
263 an installer can be made a "copy" installer of the booted OS
264
Zbigniew Jędrzejewski-Szmek2a4be3c2020-01-30 13:46:19 +0100265* systemd-repart: make it a static checker during early boot for existence and
Lennart Poettering006c44c2020-01-28 15:04:49 +0100266 absence of other partitions for trusted boot environments
267
Lennart Poettering006c44c2020-01-28 15:04:49 +0100268* systemd-repart: allow config of partition uuid
269
Lennart Poettering77b19ca2020-04-02 16:00:06 +0200270* userdb: allow username prefix searches in varlink API, allow realname and
271 realname substr searches in varlink API
Lennart Poettering006c44c2020-01-28 15:04:49 +0100272
Lennart Poettering76410e92020-04-28 20:02:39 +0200273* userdb: allow uid/gid range checks
274
Zbigniew Jędrzejewski-Szmek2a4be3c2020-01-30 13:46:19 +0100275* userdb: allow existence checks
Lennart Poettering006c44c2020-01-28 15:04:49 +0100276
Lennart Poetteringf1eb0cc2020-05-10 10:19:05 +0200277* pid1: activation by journal search expression
Lennart Poettering006c44c2020-01-28 15:04:49 +0100278
Lennart Poettering492f91d2019-12-10 23:47:06 +0100279* when switching root from initrd to host, set the machine_id env var so that
280 if the host has no machine ID set yet we continue to use the random one the
281 initrd had set.
282
Lennart Poettering173c7872019-11-29 11:51:04 +0100283* sd-event: add native support for P_ALL waitid() watching, then move PID 1 to
284 it fo reaping assigned but unknown children. This needs to some special care
285 to operate somewhat sensibly in light of priorities: P_ALL will return
286 arbitrary processes, regardless of the priority we want to watch them with,
287 hence on each event loop iteration check all processes which we shall watch
288 with higher prio explicitly, and then watch the entire rest with P_ALL.
289
290* tweak sd-event's child watching: keep a prioq of children to watch and use
291 waitid() only on the children with the highest priority until one is waitable
292 and ignore all lower-prio ones from that point on
293
Lennart Poettering173c7872019-11-29 11:51:04 +0100294* maybe introduce xattrs that can be set on the root dir of the root fs
295 partition that declare the volatility mode to use the image in. Previously I
296 thought marking this via GPT partition flags but that's not ideal since
297 that's outside of the LUKS encryption/verity verification, and we probably
298 shouldn't operate in a volatile mode unless we got told so from a trusted
299 source.
300
Lennart Poettering173c7872019-11-29 11:51:04 +0100301* figure out automatic partition discovery when combining writable root dir
302 with immutable /usr
303
Lennart Poettering97e5cc82019-08-20 16:21:01 +0200304* coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that
305 may be used to mark a whole binary as non-coredumpable. Would fix:
306 https://bugs.freedesktop.org/show_bug.cgi?id=69447
307
Lennart Poetteringf3e361c2019-11-13 12:55:59 +0100308* teach parse_timestamp() timezones like the calendar spec already knows it
309
Lennart Poettering9ef33762019-08-13 14:40:30 +0200310* beef up hibernation to optionally do swapon/swapoff immediately before/after
311 the hibernation
312
Lennart Poetteringc846b232019-07-29 12:49:13 +0200313* beef up s2h to implement a battery watch loop: instead of entering
314 hibernation unconditionally after coming back from resume make a decision
315 based on the battery load level: if battery level is above a specific
316 threshold, go to suspend again, only hibernate if below it. This means we'd
317 stick to suspend usually, but fall back to hibernation only when battery runs
318 empty (well, subject to our sampling interval). Related to this, check if we
319 can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
320 i.e. see if it can wake up machines from suspend, so that we could resume
321 automatically when the system is low on power and move automatically to
322 hibernation mode. (see
323 https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
324 section 10.2.2.8 and
325 https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
326 at the end).
327
Lennart Poetteringf293fc52019-07-25 19:25:50 +0200328* add an explicit "vertical" mode to format-table, so that "systemctl
329 status"-like outputs (i.e. with a series of field names left and values
330 right) become genuine first class citizens, and we gain automatic, sane JSON
331 output for them.
332
Lennart Poetteringf293fc52019-07-25 19:25:50 +0200333* systemd-firstboot: teach it dissector magic, so that you can point it to some
334 disk image and it will just set everything in it all behind the scenes.
335
Lennart Poettering9c230b82019-07-23 20:21:07 +0200336* We should probably replace /var/log/README, /etc/rc.d/README with symlinks
337 that are linked to these places instead of copied. After all they are
338 constant vendor data.
339
Lennart Poetteringc6526b82020-05-14 10:13:40 +0200340* maybe add kernel cmdline params: to force random seed crediting
Lennart Poettering312dc152019-07-22 10:22:56 +0200341
342* nspawn: on cgroupsv1 issue cgroup empty handler process based on host events,
343 so that we make cgroup agent logic safe
344
345* nspawn/machined: add API to invoke binary in container, then use that as
346 fallback in "machinectl shell"
Lennart Poettering72bd8522019-06-22 20:12:44 +0200347
Lennart Poetteringac5dca62019-06-23 16:13:26 +0200348* logind: rework pam_logind to also do a bus call in case of invocation from
349 user@.service, which returns the XDG_RUNTIME_DIR value, and make this
350 behaviour selectable via pam module option.
351
Lennart Poetteringc809ed72019-07-04 18:16:30 +0200352* homed:
353 - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth
354 - hook up machined/nspawn users with a varlink user query interface
355 - rollback when resize fails mid-operation
356 - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid)
357 - resize on login?
Lennart Poetteringc809ed72019-07-04 18:16:30 +0200358 - shrink fs on logout?
359 - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device.
360 - create on activate?
361 - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls?
362 - communicate clearly when usb stick is safe to remove. probably involves
363 beefing up logind to make pam session close hook synchronous and wait until
364 systemd --user is shut down.
365 - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service
366 - maybe make automatic, read-only, time-based reflink-copies of LUKS disk images (think: time machine)
Frantisek Sumsal86b52a32020-04-21 20:46:53 +0200367 - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory)
Lennart Poetteringc809ed72019-07-04 18:16:30 +0200368 - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work
369 - fingerprint authentication, pattern authentication, …
370 - make sure "classic" user records can also be managed by homed
371 - description field for groups
372 - make size of $XDG_RUNTIME_DIR configurable in user record
373 - reuse pwquality magic in firstboot
374 - query password from kernel keyring first
375 - update even if record is "absent"
376 - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends
377 - move acct mgmt stuff from pam_systemd_home to pam_systemd?
378 - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for
379 - make slice for users configurable (requires logind rework)
380 - logind: populate auto-login list bus property from PKCS#11 token
381 - when determining state of a LUKS home directory, check DM suspended sysfs file
382
Lennart Poetteringac5dca62019-06-23 16:13:26 +0200383* introduce a new per-process uuid, similar to the boot id, the machine id, the
384 invocation id, that is derived from process creds, specifically a hashed
385 combination of AT_RANDOM + getpid() + the starttime from
386 /proc/self/status. Then add these ids implicitly when logging. Deriving this
387 uuid from these three things has the benefit that it can be derived easily
388 from /proc/$PID/ in a stable, and unique way that changes on both fork() and
389 exec().
390
391* let's not GC a unit while its ratelimits are still pending
392
Lennart Poettering5daeeec2019-04-12 14:13:17 +0200393* when killing due to service watchdog timeout maybe detect whether target
394 process is under ptracing and then log loudly and continue instead.
395
Lennart Poettering5802d972019-04-28 13:00:36 +0200396* introduce a new group to own TPM devices
397
398* make rfkill uaccess controllable by default, i.e. steal rule from
399 gnome-bluetooth and friends
400
Lennart Poetteringd84520e2019-03-28 12:00:28 +0100401* tweak journald context caching. In addition to caching per-process attributes
402 keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read)
403 keyed by cgroup path, and guarded by ctime changes. This should provide us
404 with a nice speed-up on services that have many processes running in the same
405 cgroup.
406
Lennart Poettering03ccc7f2018-12-10 16:09:30 +0100407* make MAINPID= message reception checks even stricter: if service uses User=,
408 then check sending UID and ignore message if it doesn't match the user or
409 root.
410
411* maybe trigger a uevent "change" on a device if "systemctl reload xyz.device"
412 is issued.
413
Lennart Poetteringdb3cea22018-11-29 17:19:41 +0100414* when importing an fs tree with machined, optionally apply userns-rec-chown
415
416* when importing an fs tree with machined, complain if image is not an OS
417
Lennart Poettering707b3fb2018-11-26 16:18:41 +0100418* Maybe introduce a helper safe_exec() or so, which is to execve() which
419 safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit
420 to 1K implicitly, unless explicitly opted-out.
Lennart Poetteringd7b659e2018-11-26 13:41:07 +0100421
Michael Prokopd2387092019-06-27 09:54:20 +0200422* rework seccomp/nnp logic that even if User= is used in combination with
Lennart Poetteringd96c0812018-11-07 17:41:55 +0100423 a seccomp option we don't have to set NNP. For that, change uid first whil
424 keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap.
425
Lennart Poettering06bd1492018-11-13 23:05:36 +0100426* add a concept for automatically loading per-unit secrets off disk and
427 inserting them into the kernel keyring. Maybe SecretsDirectory= similar to
428 ConfigurationDirectory=.
429
Lennart Poettering8a7cf152018-11-12 13:19:07 +0100430* when no locale is configured, default to UEFI's PlatformLang variable
431
Lennart Poetteringd3584ec2018-10-17 11:38:57 +0200432* bootctl,sd-boot: actually honour the "architecture" key
433
Lennart Poetteringd96c0812018-11-07 17:41:55 +0100434* add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and
435 usefaultd() and make systemd-analyze check for it.
436
Lennart Poettering06898122018-08-07 11:01:46 +0200437* paranoia: whenever we process passwords, call mlock() on the memory
Zbigniew Jędrzejewski-Szmek309c6b12019-07-10 13:54:50 +0200438 first. i.e. look for all places we use free_and_erasep() and
Zbigniew Jędrzejewski-Szmek9ae4ef42019-07-10 13:48:55 +0200439 augment them with mlock(). Also use MADV_DONTDUMP.
Lennart Poettering06898122018-08-07 11:01:46 +0200440
Lennart Poettering32875612018-09-27 17:11:01 +0200441* Move RestrictAddressFamily= to the new cgroup create socket
442
443* support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly
444 patching around
445
Lennart Poettering76853292018-10-08 15:46:04 +0200446* maybe implicitly attach monotonic+realtime timestamps to outgoing messages in
447 log.c and sd-journal-send
448
Lennart Poettering06898122018-08-07 11:01:46 +0200449* optionally: turn on cgroup delegation for per-session scope units
450
Lennart Poetteringd3aeddb2018-10-01 15:47:50 +0200451* introduce per-unit (i.e. per-slice, per-service) journal log size limits.
452
Lennart Poettering42e18082018-06-22 17:16:18 +0200453* sd-boot: automatically load EFI modules from some drop-in dir, so that people
454 can add in file system drivers and such
455
Lennart Poettering42e18082018-06-22 17:16:18 +0200456* sd-boot: optionally, show boot menu when previous default boot item has
457 non-zero "tries done" count
458
Lennart Poettering8f2eb732018-07-02 18:22:07 +0200459* introduce an option (or replacement) for "systemctl show" that outputs all
460 properties as JSON, similar to busctl's new JSON output. In contrast to that
461 it should skip the variant type string though.
462
463* augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which
464 contains some identifier for the project, which allows us to include
465 clickable links to source files generating these log messages. The identifier
466 could be some abberviated URL prefix or so (taking inspiration from Go
467 imports). For example, for systemd we could use
468 CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is
469 sufficient to build a link by prefixing "http://" and suffixing the
470 CODE_FILE.
471
Lennart Poettering8f2eb732018-07-02 18:22:07 +0200472* Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can
473 make clickable links from log messages carrying a MESSAGE_ID, that lead to
474 some explanatory text online.
475
Lennart Poettering7bd4bcf2018-07-16 12:19:05 +0200476* maybe extend .path units to expose fanotify() per-mount change events
477
Lennart Poetteringa33ffd12018-07-20 16:38:53 +0200478* Add a "systemctl list-units --by-slice" mode or so, which rearranges the
479 output of "systemctl list-units" slightly by showing the tree structure of
480 the slices, and the units attached to them.
481
Lennart Poettering20d4b102018-08-10 16:20:42 +0200482* the a-posteriori stopping of units bound to units that disappeared logic
483 should be reworked: there should be a queue of units, and we should only
Zbigniew Jędrzejewski-Szmekbc130b62020-02-04 18:39:04 +0100484 enqueue stop jobs from a defer event that processes queue instead of
Lennart Poettering20d4b102018-08-10 16:20:42 +0200485 right-away when we find a unit that is bound to one that doesn't exist
486 anymore. (similar to how the stop-unneeded queue has been reworked the same
487 way)
Lennart Poettering4e8113b2018-06-20 19:36:06 +0200488
Lennart Poettering126708f2018-07-26 16:55:27 +0200489* nspawn: make nspawn suitable for shell pipelines: instead of triggering a
490 hangup when input is finished, send ^D, which synthesizes an EOF. Then wait
491 for hangup or ^D before passing on the EOF.
492
Lennart Poetteringbb527e12018-06-04 21:00:44 +0200493* When reloading configuration PID 1 should reset all its properties to the
494 original defaults before calling parse_config()
495
Lennart Poettering72d711e2018-05-07 17:50:31 +0200496* nspawn: greater control over selinux label?
Lennart Poetteringc7db2a92018-04-30 21:20:31 +0200497
Lennart Poetteringc633b0a2018-09-12 21:39:14 +0200498* hibernate/s2h: make this robust and safe to enable in Fedora by default.
499 Specifically:
500
501 1. add resume_offset support to the resume code (i.e. support swap files
502 properly)
Zbigniew Jędrzejewski-Szmeke83419d2018-09-26 07:31:10 +0200503 2. check if swap is on weird storage and refuse if so
Zbigniew Jędrzejewski-Szmek46c41472019-11-30 15:33:59 +0100504 3. add auto-detection of hibernation images
Lennart Poetteringc633b0a2018-09-12 21:39:14 +0200505
Lennart Poettering070d0ac2018-04-20 18:09:53 +0200506* cgroups: use inotify to get notified when somebody else modifies cgroups
507 owned by us, then log a friendly warning.
508
Lennart Poetteringe44924f2018-04-20 15:22:02 +0200509* beef up log.c with support for stripping ANSI sequences from strings, so that
510 it is OK to include them in log strings. This would be particularly useful so
511 that our log messages could contain clickable links for example for unit
512 files and suchlike we operate on.
Lennart Poettering070d0ac2018-04-20 18:09:53 +0200513
Lennart Poettering8c4c2df2018-04-16 12:37:25 +0200514* add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration)
515
516* add attach --enable and attach --now (for attach+enable+start)
517
518* sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the
519 selected user is resolvable in the service even if it ships its own /etc/passwd)
520
Lennart Poettering5da19042018-04-18 12:42:22 +0200521* Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the
Ben Boeckel5238e952019-04-26 20:22:40 -0400522 other doesn't. What a disaster. Probably to exclude it. Also
Lennart Poettering5da19042018-04-18 12:42:22 +0200523 DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative
524 numbers.
525
Lennart Poettering16270692018-06-06 11:44:58 +0200526* Check that users of inotify's IN_DELETE_SELF flag are using it properly, as
527 usually IN_ATTRIB is the right way to watch deleted files, as the former only
528 fires when a file is actually removed from disk, i.e. the link count drops to
529 zero and is not open anymore, while the latter happens when a file is
530 unlinked from any dir.
531
Lennart Poetteringbd1b3f72018-09-24 19:01:08 +0200532* port systemctl, busctl, … over to format-table.[ch]'s table formatters
Lennart Poettering5da19042018-04-18 12:42:22 +0200533
Lennart Poettering7bc756f2018-04-06 18:57:48 +0200534* pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up
535
536* add --vacuum-xyz options to coredumpctl, matching those journalctl already has.
537
Lennart Poettering53c70a22018-03-29 17:47:03 +0200538* introduce Ephemeral= unit file switch, that creates an ephemeral copy of all
539 files and directories that are left writable for a unit, and which are
540 removed after the unit goes down again. A bit like --ephemeral for
541 systemd-nspawn but for system services. If used together with RootImage= this
542 should reflink the image file itself.
543
544 Related: add Ephemeral=<path1> <path2> … which would allow marking
545 specific paths only like this.
546
Lennart Poettering53c70a22018-03-29 17:47:03 +0200547* add CopyFile= or so as unit file setting that may be used to copy files or
Ben Boeckel5238e952019-04-26 20:22:40 -0400548 directory trees from the host to the services RootImage= and RootDirectory=
Lennart Poettering53c70a22018-03-29 17:47:03 +0200549 environment. Which we can use for /etc/machine-id and in particular
550 /etc/resolv.conf. Should be smart and do something useful on read-only
551 images, for example fallback to read-only bind mounting the file instead.
552
Lennart Poetteringd9b50612018-03-20 20:26:15 +0100553* show invocation ID in systemd-run output
554
555* bypass SIGTERM state in unit files if KillSignal is SIGKILL
556
Lennart Poettering9711b1a2018-02-28 20:21:57 +0100557* add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1
558 and so on, which would mean we could report errors and such.
559
Lennart Poettering1e784322018-02-07 23:03:13 +0100560* teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4
561 project quota
Lennart Poettering0d545652018-01-31 19:53:16 +0100562
Lennart Poettering6b7b0f32018-02-14 14:28:00 +0100563* introduce DefaultSlice= or so in system.conf that allows changing where we
564 place our units by default, i.e. change system.slice to something
565 else. Similar, ManagerSlice= should exist so that PID1's own scope unit could
566 be moved somewhere else too. Finally machined and logind should get similar
567 options so that it is possible to move user session scopes and machines to a
568 different slice too by default. Usecase: people who want to put resources on
569 the entire system, with the exception of one specific service. See:
570 https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html
571
Lennart Poetteringaa79f932018-01-25 14:14:35 +0100572* maybe rework get_user_creds() to query the user database if $SHELL is used
573 for root, but only then.
574
Lennart Poettering46099c92017-12-30 15:21:12 +0100575* be stricter with fds we receive for the fdstore: close them asynchronously
576
Lennart Poettering46099c92017-12-30 15:21:12 +0100577* calenderspec: add support for week numbers and day numbers within a
578 year. This would allow us to define "bi-weekly" triggers safely.
579
Lennart Poetteringc3cd7cc2017-12-20 19:48:23 +0100580* sd-bus: add vtable flag, that may be used to request client creds implicitly
581 and asynchronously before dispatching the operation
582
Lennart Poettering06345852017-11-27 12:42:35 +0100583* make use of ethtool veth peer info in machined, for automatically finding out
584 host-side interface pointing to the container.
585
Lennart Poettering48f1b5e2017-11-24 18:29:29 +0100586* add some special mode to LogsDirectory=/StateDirectory=… that allows
587 declaring these directories without necessarily pulling in deps for them, or
588 creating them when starting up. That way, we could declare that
589 systemd-journald writes to /var/log/journal, which could be useful when we
590 doing disk usage calculations and so on.
591
Lennart Poetteringcb77e122018-03-02 16:25:27 +0100592* taint systemd if there are fewer than 65536 users assigned (userns) to the system.
Lennart Poetteringc6009ff2017-11-22 13:56:10 +0100593
Lennart Poettering899feb72018-11-16 14:30:29 +0100594* deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char
Lennart Poetteringc6009ff2017-11-22 13:56:10 +0100595
Lennart Poettering3d80d452017-11-15 11:25:38 +0100596* add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for
597 the runtime dir as we maintain for the fdstore: i.e. keep it around as long
598 as the unit is running or has a job queued.
599
Lennart Poettering5f7ecd62018-10-11 10:27:59 +0200600* support projid-based quota in machinectl for containers
Lennart Poettering5962e9d2017-11-17 18:03:00 +0100601
Lennart Poettering17b6f892017-10-24 12:18:17 +0200602* add a way to lock down cgroup migration: a boolean, which when set for a unit
603 makes sure the processes in it can never migrate out of it
604
Lennart Poettering17b6f892017-10-24 12:18:17 +0200605* blog about fd store and restartable services
606
607* document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document
608
Lennart Poettering370f9c22017-10-27 19:01:21 +0200609* rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its
610 magic meaning and is no longer upgraded to something else if set explicitly.
611
Lennart Poettering17b6f892017-10-24 12:18:17 +0200612* in the long run: permit a system with /etc/machine-id linked to /dev/null, to
613 make it lose its identity, i.e. be anonymous. For this we'd have to patch
614 through the whole tree to make all code deal with the case where no machine
615 ID is available.
616
617* optionally, collect cgroup resource data, and store it in per-unit RRD files,
618 suitable for processing with rrdtool. Add bus API to access this data, and
619 possibly implement a CPULoad property based on it.
620
Lennart Poetteringe7e4a252017-11-08 18:36:59 +0100621* beef up pam_systemd to take unit file settings such as cgroups properties as
622 parameters
623
Lennart Poettering6fc373e2017-10-09 15:22:22 +0200624* maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage
625 the quota of a the user indicated in User= via unit file settings, like the
Lennart Poettering5962e9d2017-11-17 18:03:00 +0100626 other resource management concepts. Would mix nicely with DynamicUser=1. Or
627 alternatively, do this with projids, so that we can also cover services
628 running as root. Quota should probably cover all the special dirs such as
629 StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it
630 is set, plus the whole disk space any image configured with RootImage=.
Lennart Poettering6fc373e2017-10-09 15:22:22 +0200631
Lennart Poettering9a92a972017-11-16 15:21:06 +0100632* In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant
633 disks to see if the UID is already in use.
634
Lennart Poettering2368e972017-11-13 17:21:27 +0100635* add "systemctl wait" or so, which does what "systemd-run --wait" does, but
636 for all units. It should be both a way to pin units into memory as well as a
637 wait to retrieve their exit data.
638
Lennart Poetteringfa991fb2017-09-28 11:26:11 +0200639* expose IO accounting data on the bus, show it in systemd-run --wait and log
640 about it in the resource log message
641
Lennart Poetteringfa991fb2017-09-28 11:26:11 +0200642* show whether a service has out-of-date configuration in "systemctl status" by
643 using mtime data of ConfigurationDirectory=.
644
Lennart Poetteringd73b6072017-07-10 18:25:58 +0200645* Add AddUser= setting to unit files, similar to DynamicUser=1 which however
646 creates a static, persistent user rather than a dynamic, transient user. We
647 can leverage code from sysusers.d for this.
648
Lennart Poetteringfd63f362017-04-24 18:48:10 +0200649* add some optional flag to ReadWritePaths= and friends, that has the effect
650 that we create the dir in question when the service is started. Example:
651
652 ReadWritePaths=:/var/lib/foobar
653
Lennart Poettering3576ddd2017-02-06 13:49:40 +0100654* maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for
655 the sd-journal logging socket, and, if the timeout is set to 0, sets
656 O_NONBLOCK on it. That way people can control if and when to block for
657 logging.
658
Lennart Poetteringfe6a0232017-02-28 15:24:10 +0100659* hostnamed: populate form factor data from a new hwdb database, so that old
660 yogas can be recognized as "convertible" too, even if they predate the DMI
661 "convertible" form factor
662
Lennart Poetteringd543b9f2017-02-06 18:37:28 +0100663* Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing
664 after all. Be strict however, only support the equivalent of nspawn's
665 --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such
666 as MAINPID.
667
Lennart Poetteringf59d1da2016-11-24 01:51:36 +0100668* Add ExecMonitor= setting. May be used multiple times. Forks off a process in
669 the service cgroup, which is supposed to monitor the service, and when it
670 exits the service is considered failed by its monitor.
671
Lennart Poettering33bac672017-02-06 20:26:33 +0100672* track the per-service PAM process properly (i.e. as an additional control
673 process), so that it may be queried on the bus and everything.
674
675* add a new "debug" job mode, that is propagated to unit_start() and for
676 services results in two things: we raise SIGSTOP right before invoking
677 execve() and turn off watchdog support. Then, use that to implement
678 "systemd-gdb" for attaching to the start-up of any system service in its
679 natural habitat.
680
Lennart Poettering8eb73832016-12-06 19:26:48 +0100681* gpt-auto logic: related to the above, maybe support a "secondary" root
682 partition, that is mounted to / and is writable, and where the actual root's
683 /usr is mounted into.
684
Lennart Poettering8eb73832016-12-06 19:26:48 +0100685* 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
686
Lennart Poettering67234d22016-10-25 12:43:53 +0200687* drop nss-myhostname in favour of nss-resolve?
688
Lennart Poetteringb5bdbcd2016-10-20 19:19:34 +0200689* add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and
690 then use that for the setting used in user@.service. It should be understood
691 relative to the configured default value.
692
Lennart Poetteringd21494e2016-10-06 11:54:03 +0200693* in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us
694
695* enable LockMLOCK to take a percentage value relative to physical memory
696
Lennart Poettering04397462016-08-24 20:53:56 +0200697* Permit masking specific netlink APIs with RestrictAddressFamily=
Lennart Poetteringd82047b2016-07-14 12:26:07 +0200698
Lennart Poetteringd82047b2016-07-14 12:26:07 +0200699* nspawn: support that /proc, /sys/, /dev are pre-mounted
700
Lennart Poetteringd82047b2016-07-14 12:26:07 +0200701* define gpt header bits to select volatility mode
702
Lennart Poettering42d61de2016-05-12 20:14:46 +0200703* ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc
704
Lennart Poettering04397462016-08-24 20:53:56 +0200705* ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away)
706
Lennart Poettering42d61de2016-05-12 20:14:46 +0200707* ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave)
708
Lennart Poettering42d61de2016-05-12 20:14:46 +0200709* ProtectKeyRing= to take keyring calls away
710
Lennart Poettering8ce9b832016-08-03 18:40:48 +0200711* RemoveKeyRing= to remove all keyring entries of the specified user
712
Lennart Poetteringa46eac12016-10-07 20:32:23 +0200713* ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill
714 on PID 1 with the relevant signals, and makes relevant files in /sys and
715 /proc (such as the sysrq stuff) unavailable
716
Lennart Poetteringe40a3262016-05-06 16:55:44 +0200717* make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things
Lennart Poettering89f193f2016-05-04 19:01:46 +0200718
Lennart Poettering6809de52016-04-26 15:47:03 +0200719* journalctl: make sure -f ends when the container indicated by -M terminates
720
Lennart Poettering2c5f2952016-08-15 14:48:14 +0200721* mount: automatically search for "main" partition of an image has multiple
722 partitions
723
Lennart Poettering8ce9b832016-08-03 18:40:48 +0200724* in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set,
725 find a way to map the User=/Group= of the service to the right name. This way
726 a user/group for a service only has to exist on the host for the right
727 mapping to work.
728
Lennart Poettering2c5f2952016-08-15 14:48:14 +0200729* add bus API for creating unit files in /etc, reusing the code for transient units
730
731* add bus API to remove unit files from /etc
732
733* add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only)
734
Lennart Poetteringb8c7afd2016-04-20 15:27:27 +0200735* rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the
736 kernel doesn't support linkat() that replaces existing files, currently)
737
Lennart Poettering1e555cb2016-02-24 17:20:12 +0100738* transient units: don't bother with actually setting unit properties, we
739 reload the unit file anyway
Lennart Poetteringc8048352016-02-18 22:54:57 +0100740
Lennart Poettering1e555cb2016-02-24 17:20:12 +0100741* journald: sigbus API via a signal-handler safe function that people may call
742 from the SIGBUS handler
743
Lennart Poetteringc8048352016-02-18 22:54:57 +0100744* optionally, also require WATCHDOG=1 notifications during service start-up and shutdown
745
Lennart Poettering648b1222016-02-10 22:54:33 +0100746* delay activation of logind until somebody logs in, or when /dev/tty0 pulls it
747 in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle
748
Lennart Poettering3d39e6e2016-01-14 18:08:29 +0100749* cache sd_event_now() result from before the first iteration...
750
Lennart Poetteringbd098bc2015-11-11 14:32:26 +0100751* PID1: find a way how we can reload unit file configuration for
752 specific units only, without reloading the whole of systemd
753
Lennart Poetteringf9bf1b82016-04-28 21:02:11 +0200754* add an explicit parser for LimitRTPRIO= that verifies
Lennart Poetteringde7399e2015-11-10 17:36:10 +0100755 the specified range and generates sane error messages for incorrect
Lennart Poetteringf9bf1b82016-04-28 21:02:11 +0200756 specifications.
Lennart Poetteringde7399e2015-11-10 17:36:10 +0100757
Lennart Poettering3efc8c72015-10-19 22:30:11 +0200758* when we detect that there are waiting jobs but no running jobs, do something
759
Zbigniew Jędrzejewski-Szmek5ebbb452019-12-05 10:31:55 +0100760* push CPUAffinity= also into the "cpuset" cgroup controller
Lennart Poettering03364e42015-09-17 01:19:06 +0200761
Lennart Poetteringe6a26d82015-08-16 18:25:24 +0200762* PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn)
763
Lennart Poetteringa2088fd2015-06-19 01:12:54 +0200764* there's probably something wrong with having user mounts below /sys,
Ben Boeckel5238e952019-04-26 20:22:40 -0400765 as we have for debugfs. for example, src/core/mount.c handles mounts
Lennart Poetteringa2088fd2015-06-19 01:12:54 +0200766 prefixed with /sys generally special.
767 http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html
768
Lennart Poettering8aa20382015-04-09 13:11:38 +0200769* fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline
770
Lennart Poetteringb18d23d2015-04-08 17:24:23 +0200771* docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date
772
Lennart Poettering60d17b72015-04-07 16:45:09 +0200773* add a job mode that will fail if a transaction would mean stopping
774 running units. Use this in timedated to manage the NTP service
775 state.
776 http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html
777
Lennart Poettering477e75e2015-01-28 17:48:01 +0100778* The udev blkid built-in should expose a property that reflects
779 whether media was sensed in USB CF/SD card readers. This should then
780 be used to control SYSTEMD_READY=1/0 so that USB card readers aren't
781 picked up by systemd unless they contain a medium. This would mirror
782 the behaviour we already have for CD drives.
783
Lennart Poettering2bc39682015-01-27 14:31:29 +0100784* networkd/udev: implement SR_IOV configuration in .link files:
785 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html
786
Lennart Poetteringc3a0d002014-12-19 02:07:35 +0100787* hostnamectl: show root image uuid
788
Lennart Poetteringd2f81fb2014-12-15 18:48:20 +0100789* Find a solution for SMACK capabilities stuff:
790 http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html
Lennart Poettering98cd2652014-12-12 17:30:02 +0100791
Lennart Poettering2a441c82014-12-05 14:09:33 +0100792* "systemctl preset-all" should probably order the unit files it
793 operates on lexicographically before starting to work, in order to
794 ensure deterministic behaviour if two unit files conflict (like DMs
795 do, for example)
796
Lennart Poettering0a86c1a2014-12-04 04:17:09 +0100797* synchronize console access with BSD locks:
798 http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html
799
Zbigniew Jędrzejewski-Szmeke031c222016-09-12 20:20:33 +0100800* as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads:
Lennart Poettering0a86c1a2014-12-04 04:17:09 +0100801 http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html
802
Lennart Poettering8514b672014-11-26 14:14:17 +0100803* figure out when we can use the coarse timers
804
Lennart Poettering7b0fce62014-11-18 23:35:46 +0100805* add "systemctl start -v foobar.service" that shows logs of a service
806 while the start command runs. This is non-trivial to do without
807 races though, since we should flush out all journal messages before
808 returning from the "systemctl stop".
809
Lennart Poetteringb568ef12014-11-26 12:11:39 +0100810* 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
Lennart Poetteringc2d5b3c2014-11-12 23:44:14 +0100811
Lennart Poetteringd48b7bd2014-11-07 16:31:42 +0100812* maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment=
813
Lennart Poettering8483d732014-10-22 20:24:16 +0200814* maybe allow timer units with an empty Units= setting, so that they
815 can be used for resuming the system but nothing else.
816
Kay Sievers25e773e2014-11-13 13:11:04 +0100817* what to do about udev db binary stability for apps? (raw access is not an option)
Lennart Poetteringb857e042014-10-22 12:40:49 +0200818
Lennart Poettering279f0362014-11-26 03:18:17 +0100819* systemctl: if some operation fails, show log output?
Lennart Poettering533bb262014-09-03 18:59:17 +0200820
Ben Boeckel5238e952019-04-26 20:22:40 -0400821* systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #.
Zbigniew Jędrzejewski-Szmekb42de082014-12-16 00:22:58 -0500822 Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc.
Lennart Poettering202aea42014-08-28 20:23:52 +0200823
Lennart Poettering720652b2016-01-26 13:37:42 +0100824* exponential backoff in timesyncd when we cannot reach a server
Lennart Poettering42aeb142014-08-26 03:59:05 +0200825
Lennart Poettering720652b2016-01-26 13:37:42 +0100826* timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM
David Herrmanne25b5a82015-11-16 15:05:00 +0100827
Lennart Poettering563b1bd2014-08-15 18:01:30 +0200828* merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share....
829
Tom Gundersen6bd79412015-03-24 23:05:43 +0100830* add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL
831 (throughout the codebase, not only PID1)
832
Lennart Poettering9d6db732014-07-16 00:31:27 +0200833* resolved:
Lennart Poettering9d6db732014-07-16 00:31:27 +0200834 - mDNS/DNS-SD
Lennart Poetteringccc3e8a2015-11-23 23:12:27 +0100835 - service registration
836 - service/domain/types browsing
Lennart Poettering0f47ed02014-07-31 17:47:09 +0200837 - avahi compat
Lennart Poettering9d6db732014-07-16 00:31:27 +0200838 - DNS-SD service registration from socket units
David Herrmanne25b5a82015-11-16 15:05:00 +0100839 - resolved should optionally register additional per-interface LLMNR
840 names, so that for the container case we can establish the same name
841 (maybe "host") for referencing the server, everywhere.
Lennart Poettering720652b2016-01-26 13:37:42 +0100842 - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?)
Lennart Poettering3efb8712016-06-24 11:45:06 +0200843 - hook up resolved with machined-based address resolution
Kay Sievers3f77a1b2014-07-30 17:28:04 +0200844
David Herrmanne25b5a82015-11-16 15:05:00 +0100845* refcounting in sd-resolve is borked
Lennart Poetteringe2a69292014-07-09 19:20:48 +0200846
Lennart Poettering2834ffe2014-07-01 13:51:26 +0200847* Add a new verb "systemctl top"
848
Lennart Poetteringa9407782014-07-07 11:48:06 +0200849* add new gpt type for btrfs volumes
850
Lennart Poetteringa01647e2014-06-16 12:29:51 +0200851* support empty /etc boots nicely:
Lennart Poettering3c779fa2014-06-18 00:01:07 +0200852 - nspawn/gpt-generator: introduce new gpt partition type for /usr
Lennart Poetteringa01647e2014-06-16 12:29:51 +0200853
Lennart Poettering3de03732014-05-22 16:14:50 +0900854* generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
855
Lennart Poettering37efac52014-05-05 21:18:54 +0200856* a way for container managers to turn off getty starting via $container_headless= or so...
857
Lennart Poettering7348b3a2014-05-02 17:56:01 +0200858* figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
859
Kay Sievers81429132014-06-18 03:46:44 +0200860* For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services
861 they run added to the initial transaction and thus confuse Type=idle.
Lennart Poetteringe107ed12014-04-23 22:41:44 +0200862
Lennart Poetteringedb29352014-03-14 21:10:55 +0100863* add bus api to query unit file's X fields.
864
Lennart Poettering6a3f8922014-03-05 22:31:03 +0100865* gpt-auto-generator:
Lennart Poettering2a781fc2014-03-08 04:05:48 +0100866 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
Lennart Poettering6a3f8922014-03-05 22:31:03 +0100867 - Make /home automount rather than mount?
Lennart Poettering6a3f8922014-03-05 22:31:03 +0100868
Lennart Poettering65026402014-02-24 17:34:37 +0100869* add generator that pulls in systemd-network from containers when
870 CAP_NET_ADMIN is set, more than the loopback device is defined, even
871 when it is otherwise off
Lennart Poetteringf8901862014-02-24 13:21:55 +0100872
Lennart Poetteringf9bf1b82016-04-28 21:02:11 +0200873* MessageQueueMessageSize= (and suchlike) should use parse_iec_size().
Lennart Poetteringeda8f062014-02-23 03:18:46 +0100874
Lennart Poetteringaf1082b2014-02-14 16:40:52 +0100875* implement Distribute= in socket units to allow running multiple
876 service instances processing the listening socket, and open this up
877 for ReusePort=
878
Lennart Poettering09ecd742014-01-12 20:10:33 +0800879* introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
880 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
881 should SIGSTOP all unit processes in a loop until all processes of
882 it are fully stopped. This can later be used for app management by
883 desktop UIs such as gnome-shell to freeze apps that are not visible
884 on screen, not unlike how job control works on the shell
885
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100886* cgroups:
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100887 - implement per-slice CPUFairScheduling=1 switch
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100888 - introduce high-level settings for RT budget, swappiness
889 - how to reset dynamically changed unit cgroup attributes sanely?
890 - when reloading configuration, apply new cgroup configuration
891 - when recursively showing the cgroup hierarchy, optionally also show
892 the hierarchies of child processes
893
894* transient units:
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100895 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100896
Lennart Poettering718db962013-11-19 21:12:59 +0100897* when we detect low battery and no AC on boot, show pretty splash and refuse boot
898
Lennart Poettering718db962013-11-19 21:12:59 +0100899* libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
900
Lennart Poettering966204e2013-11-11 03:03:17 +0100901* be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
902
Lennart Poettering41644622013-10-14 04:52:51 +0200903* 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
904
Lennart Poettering7f79cd72013-10-04 17:01:32 +0200905* After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
Lennart Poettering0aafd432013-09-17 10:01:08 -0500906
Jan Engelhardt19aadac2013-10-22 01:50:48 +0200907* If we try to find a unit via a dangling symlink, generate a clean
908 error. Currently, we just ignore it and read the unit from the search
Lennart Poetteringdf5f6972013-09-13 14:28:17 +0200909 path anyway.
910
Lennart Poettering04397462016-08-24 20:53:56 +0200911* refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up
Lennart Poetteringfcba5312013-09-12 18:09:00 +0200912
Lennart Poetteringbdeeb6b2013-07-10 02:01:14 +0200913* man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
914
915* load .d/*.conf dropins for device units
916
Tom Gundersen6bb648a2014-01-13 17:30:51 +0100917* sd-bus:
Lennart Poettering0d43ffe2015-08-20 12:20:14 +0200918 - EBADSLT handling
Lennart Poetteringfa607802015-01-09 21:32:29 +0100919 - GetAllProperties() on a non-existing object does not result in a failure currently
Lennart Poettering7212c602014-11-26 15:01:50 +0100920 - port to sd-resolve for connecting to TCP dbus servers
Lennart Poettering57f2a942014-11-04 17:54:40 +0100921 - 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
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100922 - see if we can drop more message validation on the sending side
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100923 - add API to clone sd_bus_message objects
Lennart Poetteringab9716c2014-01-22 20:29:57 +0100924 - longer term: priority inheritance
Lennart Poetteringdf98a872013-12-22 00:12:54 +0100925 - dbus spec updates:
Lennart Poetteringdf98a872013-12-22 00:12:54 +0100926 - NameLost/NameAcquired obsolete
927 - GVariant
Lennart Poettering2ecfc642014-03-10 23:17:42 +0100928 - path escaping
Lennart Poettering6a8b5fa2014-01-17 19:59:50 +0100929 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100930
931* sd-event
Lennart Poettering12179982013-12-13 04:03:30 +0100932 - allow multiple signal handlers per signal?
Zbigniew Jędrzejewski-Szmek0536ce52014-10-05 15:29:20 -0400933 - document chaining of signal handler for SIGCHLD and child handlers
David Herrmanne25b5a82015-11-16 15:05:00 +0100934 - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
Lennart Poetteringeb01ba52013-05-16 21:14:56 +0200935
Zbigniew Jędrzejewski-Szmek69af4502013-07-16 22:44:38 -0400936* investigate endianness issues of UUID vs. GUID
Lennart Poetteringe8a7a312013-04-24 17:18:01 -0300937
Lennart Poettering461bd8e2013-04-18 22:19:33 +0200938* dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
939 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
940
Lennart Poetteringab8e0742013-04-17 22:23:18 +0200941* add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
942
943* add a pam module that on password changes updates any LUKS slot where the password matches
944
Zbigniew Jędrzejewski-Szmekfff87a32013-04-22 20:39:40 -0400945* test/:
Zbigniew Jędrzejewski-Szmek20d52ab2018-03-13 12:25:06 +0100946 - add unit tests for config_parse_device_allow()
Lennart Poetteringb8b4d3d2013-04-09 22:20:05 +0200947
Lennart Poetteringb5c03632013-03-29 18:28:43 +0100948* seems that when we follow symlinks to units we prefer the symlink
Jan Engelhardtd28315e2014-05-03 19:15:23 +0200949 destination path over /etc and /usr. We should not do that. Instead
Lennart Poetteringb5c03632013-03-29 18:28:43 +0100950 /etc should always override /run+/usr and also any symlink
951 destination.
952
Lennart Poetteringeece8c62013-03-25 18:17:15 +0100953* when isolating, try to figure out a way how we implicitly can order
954 all units we stop before the isolating unit...
955
Lennart Poettering356ce992013-03-22 23:28:36 +0100956* teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
957
Zbigniew Jędrzejewski-Szmek6daebf92020-04-20 12:41:49 +0200958* Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add
959 ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at
960 https://github.com/systemd/systemd/pull/15109#issuecomment-607740136.
961
Lennart Poetteringc1446922014-03-21 03:27:17 +0100962* BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
963 that the boot loader should be installed to the ESP. Define a way
964 how an installer can figure out whether a BLS compliant boot loader
965 is installed.
Lennart Poettering795607b2013-03-11 17:49:33 +0100966
Lennart Poettering0be83422013-03-07 13:39:57 +0100967* think about requeuing jobs when daemon-reload is issued? usecase:
968 the initrd issues a reload after fstab from the host is accessible
969 and we might want to requeue the mounts local-fs acquired through
970 that automatically.
971
Lennart Poetteringe5ec62c2013-04-01 23:04:11 +0200972* systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
Lennart Poettering54c31a72013-02-28 19:55:48 +0100973
Zbigniew Jędrzejewski-Szmekccddd102016-04-21 22:57:06 -0400974* remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good
Lennart Poettering826872b2013-02-27 15:00:38 +0100975
Lennart Poettering3679d112013-02-27 02:24:10 +0100976* shutdown logging: store to EFI var, and store to USB stick?
977
Lennart Poettering356ce992013-03-22 23:28:36 +0100978* merge unit_kill_common() and unit_kill_context()
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100979
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100980* EFI:
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100981 - honor language efi variables for default language selection (if there are any?)
982 - honor timezone efi variables for default timezone selection (if there are any?)
Kay Sievers466784c2013-07-18 23:07:37 +0200983 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
Zbigniew Jędrzejewski-Szmek631427d2019-03-20 11:28:35 +0100984* bootctl
Zbigniew Jędrzejewski-Szmek631427d2019-03-20 11:28:35 +0100985 - recognize the case when not booted on EFI
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100986
Kay Sieversc0fe5db2013-01-27 22:59:01 +0100987* maybe do not install getty@tty1.service symlink in /etc but in /usr?
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100988
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100989* print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
990
Lennart Poettering205b7fa2013-01-07 22:15:48 +0100991* mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
992
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100993* logind:
994 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
Lennart Poetteringb44be3e2013-01-25 21:11:59 +0100995 - logind: wakelock/opportunistic suspend support
996 - Add pretty name for seats in logind
997 - logind: allow showing logout dialog from system?
Lennart Poetteringf38afcd2013-11-28 18:42:00 +0100998 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
999 - if pam_systemd is invoked by su from a process that is outside of a
1000 any session we should probably just become a NOP, since that's
1001 usually not a real user session but just some system code that just
1002 needs setuid().
Lennart Poettering279f0362014-11-26 03:18:17 +01001003 - logind: make the Suspend()/Hibernate() bus calls wait for the for
1004 the job to be completed. before returning, so that clients can wait
1005 for "systemctl suspend" to finish to know when the suspending is
1006 complete.
1007 - logind: when the power button is pressed short, just popup a
1008 logout dialog. If it is pressed for 1s, do the usual
1009 shutdown. Inspiration are Macs here.
Lennart Poettering279f0362014-11-26 03:18:17 +01001010 - expose "Locked" property on logind sesison objects
David Herrmanne25b5a82015-11-16 15:05:00 +01001011 - maybe allow configuration of the StopTimeout for session scopes
1012 - rename session scope so that it includes the UID. THat way
1013 the session scope can be arranged freely in slices and we don't have
1014 make assumptions about their slice anymore.
1015 - follow PropertiesChanged state more closely, to deal with quick logouts and
1016 relogins
Lennart Poettering77b19ca2020-04-02 16:00:06 +02001017 - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set
Lennart Poettering95b4be12012-12-23 22:38:21 +01001018
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001019* journal:
Lennart Poettering57f2a942014-11-04 17:54:40 +01001020 - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001021 - journald: also get thread ID from client, plus thread name
1022 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
1023 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
Jan Engelhardtd28315e2014-05-03 19:15:23 +02001024 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001025 - declare the local journal protocol stable in the wiki interface chart
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001026 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
1027 - journald: when dropping msgs due to ratelimit make sure to write
1028 "dropped %u messages" not only when we are about to print the next
Ben Boeckel5238e952019-04-26 20:22:40 -04001029 message that works, but already after a short timeout
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001030 - check if we can make journalctl by default use --follow mode inside of less if called without args?
1031 - maybe add API to send pairs of iovecs via sd_journal_send
Lennart Poetteringf47ec8e2013-03-05 18:59:14 +01001032 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001033 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
1034 and !FOOBAR for events without FOOBAR.
Zbigniew Jędrzejewski-Szmek038cf332015-01-12 19:15:02 -05001035 - journal: store timestamp of journal_file_set_offline() int he header,
1036 so it is possible to display when the file was last synced.
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001037 - 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.
1038 - journal: find a way to allow dropping history early, based on priority, other rules
1039 - journal: When used on NFS, check payload hashes
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001040 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
1041 - refuse taking lower-case variable names in sd_journal_send() and friends.
1042 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
1043 - journal: deal nicely with byte-by-byte copied files, especially regards header
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001044 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
Josh Triplett601d9d62013-04-19 14:13:42 -07001045 - Replace utmp, wtmp, btmp, and lastlog completely with journal
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001046 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001047 - when a kernel driver logs in a tight loop, we should ratelimit that too.
1048 - journald: optionally, log debug messages to /run but everything else to /var
1049 - journald: when we drop syslog messages because the syslog socket is
1050 full, make sure to write how many messages are lost as first thing
1051 to syslog when it works again.
Lennart Poettering279f0362014-11-26 03:18:17 +01001052 - journald: allow per-priority and per-service retention times when rotating/vacuuming
1053 - journald: make use of uid-range.h to managed uid ranges to split
1054 journals in.
1055 - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
1056 - improve journalctl performance by loading journal files
1057 lazily. Encode just enough information in the file name, so that we
1058 do not have to open it to know that it is not interesting for us, for
1059 the most common operations.
David Herrmanne25b5a82015-11-16 15:05:00 +01001060 - man: document that corrupted journal files is nothing to act on
David Herrmanne25b5a82015-11-16 15:05:00 +01001061 - rework journald sigbus stuff to use mutex
1062 - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our
1063 services that run under their own user ids, and use User= (but only
1064 in a world where userns is ubiquitous since otherwise we cannot
1065 invoke those daemons on the host AND in a container anymore). Also,
1066 if LimitNPROC= is used without User= we should warn and refuse
1067 operation.
1068 - journalctl --verify: don't show files that are currently being
1069 written to as FAIL, but instead show that their are being written to.
1070 - add journalctl -H that talks via ssh to a remote peer and passes through
1071 binary logs data
David Herrmanne25b5a82015-11-16 15:05:00 +01001072 - add a version of --merge which also merges /var/log/journal/remote
David Herrmanne25b5a82015-11-16 15:05:00 +01001073 - journalctl: -m should access container journals directly by enumerating
1074 them via machined, and also watch containers coming and going.
1075 Benefit: nspawn --ephemeral would start working nicely with the journal.
1076 - assign MESSAGE_ID to log messages about failed services
Lennart Poettering59659842012-11-22 20:16:15 +01001077
Zbigniew Jędrzejewski-Szmek590171d2017-12-14 14:12:39 +01001078* add a test if all entries in the catalog are properly formatted.
1079 (Adding dashes in a catalog entry currently results in the catalog entry
1080 being silently skipped. journalctl --update-catalog must warn about this,
1081 and we should also have a unit test to check that all our message are OK.)
1082
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001083* document:
Zbigniew Jędrzejewski-Szmek8b8f2592013-12-25 22:53:09 -05001084 - document that deps in [Unit] sections ignore Alias= fields in
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001085 [Install] units of other units, unless those units are disabled
1086 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001087 - document that service reload may be implemented as service reexec
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001088 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
1089 - document systemd-journal-flush.service properly
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001090 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
1091 - man: document the very specific env the shutdown drop-in tools live in
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001092 - man: add more examples to man pages
1093 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
Zbigniew Jędrzejewski-Szmek17ec5312018-12-20 16:09:48 +01001094 - document root=gpt-auto properly
Lennart Poetteringe4181482012-11-20 21:33:49 +01001095
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001096* systemctl:
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001097 - add systemctl switch to dump transaction without executing it
1098 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
1099 - "systemctl disable" on a static unit prints no message and does
1100 nothing. "systemctl enable" does nothing, and gives a bad message
1101 about it. Should fix both to print nice actionable messages.
1102 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
1103 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
Jan Engelhardtd28315e2014-05-03 19:15:23 +02001104 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001105 - systemctl: "Journal has been rotated since unit was started." message is misleading
Torstein Husebø61233822016-07-10 14:48:23 +02001106 - systemctl status output should include list of triggering units and their status
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001107
1108* unit install:
1109 - "systemctl mask" should find all names by which a unit is accessible
1110 (i.e. by scanning for symlinks to it) and link them all to /dev/null
Lennart Poettering8ed20652012-11-18 23:32:09 +01001111
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001112* timer units:
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001113 - timer units should get the ability to trigger when:
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001114 o DST changes
Lennart Poettering90e071d2013-11-05 00:48:47 +01001115 - Modulate timer frequency based on battery state
Kay Sieversd2e83c22012-11-04 15:47:08 +01001116
Lennart Poetteringa19554e2012-10-24 01:05:40 +02001117* add libsystemd-password or so to query passwords during boot using the password agent logic
1118
Lennart Poetteringa7a3f282012-10-15 16:28:04 +02001119* clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
1120
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001121* on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
Lennart Poettering08f95882012-10-03 11:37:06 -04001122
Lennart Poetteringf59d1da2016-11-24 01:51:36 +01001123* make repeated alt-ctrl-del presses printing a dump
Lennart Poetteringdcfc4b22012-08-03 21:49:06 +02001124
Lennart Poettering71ef24d2012-10-02 13:11:26 -04001125* hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
1126
Jan Engelhardtd28315e2014-05-03 19:15:23 +02001127* currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
Lennart Poettering1b898842012-09-27 17:18:13 +02001128
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001129* nspawn:
David Herrmanne25b5a82015-11-16 15:05:00 +01001130 - emulate /dev/kmsg using CUSE and turn off the syslog syscall
1131 with seccomp. That should provide us with a useful log buffer that
1132 systemd can log to during early boot, and disconnect container logs
1133 from the kernel's logs.
1134 - as soon as networkd has a bus interface, hook up --network-interface=,
1135 --network-bridge= with networkd, to trigger netdev creation should an
1136 interface be missing
David Herrmanne25b5a82015-11-16 15:05:00 +01001137 - a nice way to boot up without machine id set, so that it is set at boot
1138 automatically for supporting --ephemeral. Maybe hash the host machine id
1139 together with the machine name to generate the machine id for the container
1140 - fix logic always print a final newline on output.
1141 https://github.com/systemd/systemd/pull/272#issuecomment-113153176
1142 - should optionally support receiving WATCHDOG=1 messages from its payload
1143 PID 1...
David Herrmanne25b5a82015-11-16 15:05:00 +01001144 - optionally automatically add FORWARD rules to iptables whenever nspawn is
1145 running, remove them when shut down.
David Herrmanne25b5a82015-11-16 15:05:00 +01001146
Zbigniew Jędrzejewski-Szmek347a17d2016-12-10 01:41:36 -05001147* dissect
1148 - refuse mounting over a mount point
1149 - automatically discover .roothash files in dissect, similarly to nspawn
1150
David Herrmanne25b5a82015-11-16 15:05:00 +01001151* machined:
David Herrmanne25b5a82015-11-16 15:05:00 +01001152 - add an API so that libvirt-lxc can inform us about network interfaces being
1153 removed or added to an existing machine
1154 - "machinectl migrate" or similar to copy a container from or to a
1155 difference host, via ssh
David Herrmanne25b5a82015-11-16 15:05:00 +01001156 - introduce systemd-nspawn-ephemeral@.service, and hook it into
1157 "machinectl start" with a new --ephemeral switch
1158 - "machinectl status" should also show internal logs of the container in
1159 question
David Herrmanne25b5a82015-11-16 15:05:00 +01001160 - "machinectl history"
1161 - "machinectl diff"
1162 - "machinectl commit" that takes a writable snapshot of a tree, invokes a
1163 shell in it, and marks it read-only after use
1164
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001165* cryptsetup:
Lennart Poetteringb44be3e2013-01-25 21:11:59 +01001166 - cryptsetup-generator: allow specification of passwords in crypttab itself
Lennart Poettering5f1dac62013-04-29 19:57:29 -03001167 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
Lennart Poetteringf8019682012-09-21 20:52:23 +02001168
Lennart Poettering424a19f2012-09-14 20:02:52 +02001169* hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
Lennart Poettering41f91722012-09-18 11:27:56 +02001170 https://bugs.freedesktop.org/show_bug.cgi?id=54712
Lennart Poettering424a19f2012-09-14 20:02:52 +02001171
Zbigniew Jędrzejewski-Szmek83fefc82017-10-06 10:04:49 +02001172* add a dependency on standard-conf.xml and other included files to man pages
1173
Lennart Poettering68f16002012-08-13 15:39:25 +02001174* MountFlags=shared acts as MountFlags=slave right now.
1175
Lennart Poetteringfd4d89b2012-08-08 18:10:35 +02001176* properly handle loop back mounts via fstab, especially regards to fsck/passno
1177
Lennart Poettering47ae7202012-07-27 12:21:39 +02001178* initialize the hostname from the fs label of /, if /etc/hostname does not exist?
1179
Kay Sieversabd55b12013-01-17 03:30:55 +01001180* udev:
Kay Sieversabd55b12013-01-17 03:30:55 +01001181 - move to LGPL
Kay Sieversabd55b12013-01-17 03:30:55 +01001182 - kill scsi_id
1183 - add trigger --subsystem-match=usb/usb_device device
Tom Gundersene8d842a2014-02-21 21:41:48 +01001184 - reimport udev db after MOVE events for devices without dev_t
Kay Sievers4ee71782012-04-30 00:46:38 +02001185
Lennart Poettering7f110ff2012-03-12 22:22:16 +01001186* There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
1187
Lennart Poetteringd0e5a332012-02-20 19:56:14 +01001188* add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
1189
David Herrmanne25b5a82015-11-16 15:05:00 +01001190* coredump:
1191 - save coredump in Windows/Mozilla minidump format
Zbigniew Jędrzejewski-Szmek73a99162016-09-27 12:40:54 +02001192 - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps
Lennart Poettering87a8baa2012-01-17 13:30:58 +01001193
1194* support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
1195
Kay Sieversf9576322011-09-21 19:33:52 +02001196* be able to specify a forced restart of service A where service B depends on, in case B
1197 needs to be auto-respawned?
1198
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001199* tmpfiles:
Lennart Poetteringf38afcd2013-11-28 18:42:00 +01001200 - apply "x" on "D" too (see patch from William Douglas)
Zbigniew Jędrzejewski-Szmek614cc342015-01-18 18:28:17 -05001201 - instead of ignoring unknown fields, reject them.
David Herrmanne25b5a82015-11-16 15:05:00 +01001202 - creating new directories/subvolumes/fifos/device nodes
1203 should not follow symlinks. None of the other adjustment or creation
1204 calls follow symlinks.
Lennart Poettering12580972011-07-11 21:10:48 +02001205
Lennart Poetteringa4c279f2011-07-08 21:39:10 +02001206* make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
1207
Lennart Poetteringf28f1da2011-05-20 01:57:20 +02001208* verify that the AF_UNIX sockets of a service in the fs still exist
1209 when we start a service in order to avoid confusion when a user
1210 assumes starting a service is enough to make it accessible
1211
Lennart Poettering88a07672011-05-12 16:14:44 +02001212* Make it possible to set the keymap independently from the font on
1213 the kernel cmdline. Right now setting one resets also the other.
1214
Lennart Poettering71092d72011-07-29 05:01:47 +02001215* and a dbus call to generate target from current state
Lennart Poettering916abb22011-05-17 19:37:03 +02001216
Lennart Poettering68c7d002011-04-05 00:24:00 +02001217* write blog stories about:

Lennart Poettering73090dc2011-04-19 06:06:41 +02001235
Lennart Poettering21bdae12011-07-02 01:44:49 +02001236* investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support.
1237
Lennart Poettering59fee422010-09-28 21:49:26 +02001238* dot output for --test showing the 'initial transaction'
1239
David Herrmanne25b5a82015-11-16 15:05:00 +01001240* pid1:
David Herrmanne25b5a82015-11-16 15:05:00 +01001241 - When logging about multiple units (stopping BoundTo units, conflicts, etc.),
1242 log both units as UNIT=, so that journalctl -u triggers on both.
1243 - generate better errors when people try to set transient properties
1244 that are not supported...
1245 http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html
1246 - maybe introduce WantsMountsFor=? Usecase:
1247 http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html
1248 - recreate systemd's D-Bus private socket file on SIGUSR2
David Herrmanne25b5a82015-11-16 15:05:00 +01001249 - move PAM code into its own binary
1250 - when we automatically restart a service, ensure we restart its rdeps, too.
David Herrmanne25b5a82015-11-16 15:05:00 +01001251 - hide PAM options in fragment parser when compile time disabled
1252 - Support --test based on current system state
1253 - 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().
1254 - after deserializing sockets in socket.c we should reapply sockopts and things
David Herrmanne25b5a82015-11-16 15:05:00 +01001255 - drop PID 1 reloading, only do reexecing (difficult: Reload()
1256 currently is properly synchronous, Reexec() is weird, because we
1257 cannot delay the response properly until we are back, so instead of
1258 being properly synchronous we just keep open the fd and close it
1259 when done. That means clients do not get a successful method reply,
1260 but much rather a disconnect on success.
1261 - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
1262 - when a bus name of a service disappears from the bus make sure to queue further activation requests
1263
1264* unit files:
1265 - allow port=0 in .socket units
1266 - maybe introduce ExecRestartPre=
1267 - add ReloadSignal= for configuring a reload signal to use
1268 - implement Register= switch in .socket units to enable registration
1269 in Avahi, RPC and other socket registration services.
1270 - allow Type=simple with PIDFile=
1271 https://bugzilla.redhat.com/show_bug.cgi?id=723942
1272 - allow writing multiple conditions in unit files on one line
David Herrmanne25b5a82015-11-16 15:05:00 +01001273 - introduce Type=pid-file
David Herrmanne25b5a82015-11-16 15:05:00 +01001274 - introduce mix of BindTo and Requisite
1275 - add a concept of RemainAfterExit= to scope units
David Herrmanne25b5a82015-11-16 15:05:00 +01001276 - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely
Zbigniew Jędrzejewski-Szmeke5171292019-12-13 19:25:50 +01001277 - add verification of [Install] section to systemd-analyze verify
David Herrmanne25b5a82015-11-16 15:05:00 +01001278
Tom Gundersenaf6f0d42013-10-26 00:34:01 +02001279* udev-link-config:
1280 - Make sure ID_PATH is always exported and complete for
1281 network devices where possible, so we can safely rely
1282 on Path= matching
Tom Gundersenaf6f0d42013-10-26 00:34:01 +02001283
Tom Gundersen88e4d1d2013-11-27 23:15:04 +01001284* sd-rtnl:
Tom Gundersen88e4d1d2013-11-27 23:15:04 +01001285 - add support for more attribute types
Tom Gundersenc589a0e2014-03-31 11:30:59 +02001286 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
Tom Gundersen88e4d1d2013-11-27 23:15:04 +01001287
Tom Gundersen0a4b9a02013-12-04 13:14:23 +01001288* networkd:
Tom Gundersenc74ecd72014-01-11 20:19:10 +00001289 - add more keys to [Route] and [Address] sections
1290 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
Tom Gundersene8d842a2014-02-21 21:41:48 +01001291 - add reduced [Link] support to .network files
Umut Tezduyar Lindskog798e1742014-04-27 23:45:42 +02001292 - properly handle routerless dhcp leases
Jan Engelhardta8eaaee2014-08-03 07:11:37 +02001293 - work with non-Ethernet devices
David Herrmanne25b5a82015-11-16 15:05:00 +01001294 - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from?
David Herrmanne25b5a82015-11-16 15:05:00 +01001295 - the DHCP lease data (such as NTP/DNS) is still made available when
1296 a carrier is lost on a link. It should be removed instantly.
1297 - expose in the API the following bits:
Zbigniew Jędrzejewski-Szmeke2da6492020-05-19 08:55:46 +02001298 - option 15, domain name
Zbigniew Jędrzejewski-Szmek38b38502020-04-14 10:37:40 +02001299 - option 12, hostname and/or option 81, fqdn
David Herrmanne25b5a82015-11-16 15:05:00 +01001300 - option 123, 144, geolocation
1301 - option 252, configure http proxy (PAC/wpad)
1302 - provide a way to define a per-network interface default metric value
1303 for all routes to it. possibly a second default for DHCP routes.
1304 - allow Name= to be specified repeatedly in the [Match] section. Maybe also
1305 support Name=foo*|bar*|baz ?
1306 - duplicate address check for static IPs (like ARPCHECK in network-scripts)
David Herrmanne25b5a82015-11-16 15:05:00 +01001307 - whenever uplink info changes, make DHCP server send out FORCERENEW
Tom Gundersen155e8b92014-03-20 20:19:59 +01001308
Zbigniew Jędrzejewski-Szmekd5e172d2020-05-24 22:02:47 +02001309* Figure out how to do unittests of networkd's state serialization

Tom Gundersenac976532014-05-16 00:26:37 +02001311* dhcp:
Tom Gundersen424a8732014-05-21 16:46:14 +02001312 - figure out how much we can increase Maximum Message Size
Tom Gundersenac976532014-05-16 00:26:37 +02001313
Patrik Flykt37d8b532014-06-24 16:24:50 +03001314* dhcp6:
1315 - add functions to set previously stored IPv6 addresses on startup and get
1316 them at shutdown; store them in client->ia_na
1317 - write more test cases
Patrik Flykt37d8b532014-06-24 16:24:50 +03001318 - implement reconfigure support, see 5.3., 15.11. and 22.20.
Patrik Flykt37d8b532014-06-24 16:24:50 +03001319 - implement support for temporary adressess (IA_TA)
Patrik Flykt37d8b532014-06-24 16:24:50 +03001320 - implement dhcpv6 authentication
1321 - investigate the usefulness of Confirm messages; i.e. are there any
1322 situations where the link changes without any loss in carrier detection
1323 or interface down
1324 - some servers don't do rapid commit without a filled in IA_NA, verify
1325 this behavior
Zbigniew Jędrzejewski-Szmek4a77c532016-10-02 14:51:49 +02001326 - RouteTable= ?
