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

f38afcd0 | 13 | * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros. |
bafb15ba | 14 | |
07eabc2b LB |
15 | * dbus: |
16 | - natively watch for dbus-*.service symlinks (PENDING) | |
17 | - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service | |
18 | ||
19 | * kernel: add device_type = "fb", "fbcon" to class "graphics" | |
20 | ||
21 | * /usr/bin/service should actually show the new command line | |
22 | ||
23 | * fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus= | |
24 | ||
25 | * neither pkexec nor sudo initialize environ[] from the PAM environment? | |
26 | ||
27 | * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it | |
28 | ||
29 | * register catalog database signature as file magic | |
30 | ||
31 | * zsh shell completion: | |
32 | - <command> <verb> -<TAB> should complete options, but currently does not | |
33 | - systemctl add-wants,add-requires | |
34 | ||
35 | * systemctl status should know about 'systemd-analyze calendar ... --iterations=' | |
36 | * If timer has just OnInactiveSec=..., it should fire after a specified time | |
37 | after being started. | |
38 | ||
39 | * write blog stories about: | |
40 | - hwdb: what belongs into it, lsusb | |
41 | - enabling dbus services | |
42 | - how to make changes to sysctl and sysfs attributes | |
43 | - remote access | |
44 | - how to pass throw-away units to systemd, or dynamically change properties of existing units | |
45 | - testing with Harald's awesome test kit | |
46 | - auto-restart | |
47 | - how to develop against journal browsing APIs | |
48 | - the journal HTTP iface | |
49 | - non-cgroup resource management | |
50 | - dynamic resource management with cgroups | |
51 | - refreshed, longer missions statement | |
52 | - calendar time events | |
53 | - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell | |
54 | - how to create your own target | |
55 | - instantiated apache, dovecot and so on | |
56 | - hooking a script into various stages of shutdown/rearly booot | |
57 | ||
58 | Regularly: | |
59 | ||
60 | * look for close() vs. close_nointr() vs. close_nointr_nofail() | |
61 | ||
62 | * check for strerror(r) instead of strerror(-r) | |
63 | ||
64 | * pahole | |
65 | ||
66 | * set_put(), hashmap_put() return values check. i.e. == 0 does not free()! | |
67 | ||
68 | * use secure_getenv() instead of getenv() where appropriate | |
69 | ||
70 | * link up selected blog stories from man pages and unit files Documentation= fields | |
71 | ||
5e524b40 LP |
72 | Janitorial Clean-ups: |
73 | ||
5e524b40 LP |
74 | * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again |
75 | ||
bb527e11 LP |
76 | * rework mount.c and swap.c to follow proper state enumeration/deserialization |
77 | semantics, like we do for device.c now | |
78 | ||
c6407108 LP |
79 | Features: |
80 | ||
598e4315 LP |
81 | * systemd creds hookup with qemu fw_cfg. (Quite possibly might not need any |
82 | code at all, given the fw_cfg stuff are just files, but we should then | |
83 | document how to use it). Goal: provide symmetric ways to pass creds to nspawn | |
84 | containers and qemu VMs. (maybe also pick up env vars from fw_cfg?) | |
85 | ||
86 | * beef up sd_notify() to support AV_VSOCK in $NOTIFY_SOCKET, so that VM | |
197be532 LP |
87 | managers can get ready notifications from VMs, just like container managers |
88 | from their payload. Also pick up address from qemu/fw_cfg if set there. | |
89 | (which has benefits, given SecureBoot and kernel cmdline are not necessarily | |
90 | friends.) | |
598e4315 LP |
91 | |
92 | * maybe write a tool that binds an AF_VFSOCK socket, then invokes qemu, | |
93 | extending the command line to enable vsock on the VM, and using fw_cfg to | |
94 | configure socket address. | |
95 | ||
3e3c49cb LP |
96 | * sd-boot: rework random seed handling following recent kernel changes: always |
97 | pass seed to kernel, but credit only if secure boot is used | |
98 | ||
99 | * sd-boot: hash data from GetNextHighMonotonicCount() into updated random seed, | |
100 | so that we might even open up up the random seed logic to non-SecureBoot | |
101 | systems? | |
102 | ||
103 | * sd-boot: add menu item for shutdown? or hotkey? | |
104 | ||
2cf120f7 LP |
105 | * sd-device has an API to create an sd_device object from a device id, but has |
106 | no api to query the device id | |
107 | ||
108 | * sd-device should return the devnum type (i.e. 'b' or 'c') via some API for an | |
109 | sd_device object, so that data passed into sd_device_new_from_devnum() can | |
110 | also be queried. | |
111 | ||
666efe94 LP |
112 | * udevadm: a new "tree" verb that shows tree of devices as syspath hierarchy, |
113 | along with their properties. uninitialized devices should be greyed out. | |
114 | ||
115 | * bootctl: show whether UEFI audit mode is available | |
e4f92a62 LP |
116 | |
117 | * dissect: rework how we access partitions: instead of letting the kernel probe | |
118 | partition tables asynchronously, just pass the stuff we parsed in userspace | |
119 | to the kernel via BLKPG_ADD_PARTITION. Benefit: we don't have to wait for | |
120 | kernel/netlink/udev, but can run this synchronously without chance of losing | |
121 | events or similar. | |
122 | ||
5b89bff5 LP |
123 | * sd-event: optionally, if per-event source rate limit is hit, downgrade |
124 | priority, but leave enabled, and once ratelimit window is over, upgrade | |
125 | priority again. That way we can combat event source starvation without | |
126 | stopping processing events from one source entirely. | |
127 | ||
e4f92a62 LP |
128 | * sd-event: similar to existing inotify support add fanotify support (given |
129 | that apparently new features in this area are only going to be added to the | |
130 | latter). | |
5b89bff5 LP |
131 | |
132 | * sd-event: add 1st class event source for clock changes | |
133 | ||
134 | * sd-event: add 1st class event source for timezone changes | |
135 | ||
9e83d3e4 LP |
136 | * support uefi/http boots with sd-boot: instead of looking for dropin files in |
137 | /loader/entries/ dir, look for a file /loader/entries/SHA256SUMS and use that | |
138 | as directory manifest. The file would be a standard directory listing as | |
139 | generated by GNU sha256sums. | |
140 | ||
d360eafb LP |
141 | * initialize machine ID from systemd credential picked up from the ESP via |
142 | sd-stub, so that machine ID is stable even on systems where unified kernels | |
143 | are used, and hence kernel cmdline cannot be modified locally | |
144 | ||
145 | * in gpt-auto-generator: check partition uuids against such uuids supplied via | |
146 | sd-stub credentials. That way, we can support parallel OS installations with | |
147 | pre-built kernels. | |
148 | ||
149 | * sysext: measure all activated sysext into a TPM PCR | |
150 | ||
151 | * maybe add a "syscfg" concept, that is almost entirely identical to "sysext", | |
152 | but operates on /etc/ instead of /usr/ and /opt/. Use case would be: trusted, | |
153 | authenticated, atomic, additive configuration management primitive: drop in a | |
154 | configuration bundle, and activate it, so that it is instantly visible, | |
155 | comprehensively. | |
156 | ||
157 | * systemd-dissect: show available versions inside of a disk image, i.e. if | |
158 | multiple versions are around of the same resource, show which ones. (in other | |
159 | words: show partition labels). | |
160 | ||
161 | * systemd-nspawn: make boot assessment do something sensible in a | |
162 | container. i.e send an sd_notify() from payload to container manager once | |
163 | boot-up is completed successfully, and use that in nspawn for dealing with | |
164 | boot counting, implemented in the partition table labels and directory names. | |
165 | ||
166 | * maybe add a generator that reads /proc/cmdline, looks for | |
167 | systemd.pull-raw-portable=, systemd-pull-raw-sysext= and similar switches | |
168 | that take an URL as parameter. It then generates service units for | |
b17a681b | 169 | systemd-pull calls that download these URLs if not installed yet. usecase: |
d360eafb LP |
170 | invoke a VM or nspawn container in a way it automatically deploys/runs these |
171 | images as OS payloads. i.e. have a generic OS image you can point to any | |
172 | payload you like, which is then downloaded, securely verified and run. | |
173 | ||
dca92ca3 LP |
174 | * improve scope units to support creation by pidfd instead of by PID |
175 | ||
e4f92a62 | 176 | * deprecate cgroupsv1 further (print log message at boot) |
f1a147f2 LP |
177 | |
178 | * systemd-dissect: add --cat switch for dumping files such as /etc/os-release | |
179 | ||
f5d0f21c LP |
180 | * per-service sandboxing option: ProtectIds=. If used, will overmount |
181 | /etc/machine-id and /proc/sys/kernel/random/boot_id with synthetic files, to | |
182 | make it harder for the service to identify the host. Depending on the user | |
183 | setting it should be fully randomized at invocation time, or a hash of the | |
184 | real thing, keyed by the unit name or so. Of course, there are other ways to | |
185 | get these IDs (e.g. journal) or similar ids (e.g. MAC addresses, DMI ids, CPU | |
186 | ids), so this knob would only be useful in combination with other lockdown | |
187 | options. Particularly useful for portable services, and anything else that | |
188 | uses RootDirectory= or RootImage=. (Might also over-mount | |
189 | /sys/class/dmi/id/*{uuid,serial} with /dev/null). | |
190 | ||
63a185dc LP |
191 | * journalctl/timesyncd: whenever timesyncd acquires a synchronization from NTP, |
192 | create a structured log entry that contains boot ID, monotonic clock and | |
193 | realtime clock (I mean, this requires no special work, as these three fields | |
194 | are implicit). Then in journalctl when attempting to display the realtime | |
195 | timestamp of a log entry, first search for the closest later log entry | |
196 | of this kinda that has a matching boot id, and convert the monotonic clock | |
197 | timestamp of the entry to the realtime clock using this info. This way we can | |
198 | retroactively correct the wallclock timestamps, in particular for systems | |
199 | without RTC, i.e. where initially wallclock timestamps carry rubbish, until | |
200 | an NTP sync is acquired. | |
201 | ||
45cab6e3 LP |
202 | * kernel-install: |
203 | - add --all switch for rerunning kernel-install for all installed kernels | |
204 | - maybe add env var that shortcuts kernel-install for installers that want to | |
205 | call it at the end only | |
206 | ||
a57d72ce LP |
207 | * doc: prep a document explaining resolved's internal objects, i.e. Query |
208 | vs. Question vs. Transaction vs. Stream and so on. | |
209 | ||
a5a316e7 LP |
210 | * doc: prep a document explaining PID 1's internal logic, i.e. transactions, |
211 | jobs, units | |
212 | ||
4cddc18d LP |
213 | * bootspec: remove tries counter from boot entry ids |
214 | ||
a57d72ce LP |
215 | * bootspec: bring UEFI and userspace enumeration of bootspec entries back into |
216 | sync, i.e. parse out tries in both | |
217 | ||
594f64f4 LP |
218 | * automatically ignore threaded cgroups in cg_xyz(). |
219 | ||
e6f48be8 LP |
220 | * add linker script that implicitly adds symbol for build ID and new coredump |
221 | json package metadata, and use that when logging | |
222 | ||
f08e143c LP |
223 | * systemd-dissect: show GPT disk UUID in output |
224 | ||
225 | * Enable RestricFileSystems= for all our long-running services (similar: | |
226 | RestrictNetworkInterfaces=) | |
227 | ||
228 | * Add systemd-analyze security checks for RestrictFileSystems= and | |
229 | RestrictNetworkInterfaces= | |
230 | ||
1ccfb792 LP |
231 | * cryptsetup/homed: implement TOTP authentication backed by TPM2 and its |
232 | internal clock. | |
233 | ||
1ccfb792 | 234 | * nspawn: optionally set up nftables/iptables routes that forward UDP/TCP |
f08e143c | 235 | traffic on port 53 to resolved stub 127.0.0.54 |
e0c311b1 | 236 | |
f5ba8115 LP |
237 | * man: rework os-release(5), and clearly separate our extension-release.d/ and |
238 | initrd-release parts, i.e. list explicitly which fields are about what. | |
239 | ||
240 | * sysext: before applying a sysext, do a superficial validation run so that | |
241 | things are not rearranged to wildy. I.e. protect against accidental fuckups, | |
242 | such as masking out /usr/lib/ or so. We should probably refuse if existing | |
243 | inodes are replaced by other types of inodes or so. | |
244 | ||
245 | * sysext: ensure one can build a sysext that can safely apply to *any* system | |
246 | (because it contains only static go binaries in /opt/ or so) | |
247 | ||
af11e0ef LP |
248 | * userdb: when synthesizing NSS records, pick "best" password from defined |
249 | passwords, not just the first. i.e. if there are multiple defined, prefer | |
250 | unlocked over locked and prefer non-empty over empty. | |
251 | ||
252 | * maybe add a tool inspired by the GPT auto discovery spec that runs in the | |
253 | initrd and rearranges the rootfs hierarchy via bind mounts, if | |
254 | enabled. Specifically in some top-level dir /@auto/ it will look for | |
255 | dirs/symlinks/subvolumes that are named after their purpose, and optionally | |
256 | encode a version as well as assessment counters, and then mount them into the | |
257 | file system tree to boot into, similar to how we do that for the gpt auto | |
258 | logic. Maybe then bind mount the original root into /.superior or something | |
259 | like that (so that update tools can look there). Further discussion in this | |
260 | thread: | |
261 | https://lists.freedesktop.org/archives/systemd-devel/2021-November/047059.html | |
262 | The GPT dissection logic should automatically enable this tool whenever we | |
263 | detect a specially marked root fs (i.e introduce a new generic root gpt type | |
264 | for this, that is arch independent). The also implement this in the image | |
265 | dissection logic, so that nspawn/RootImage= and so on grok it. Maybe make | |
266 | generic enough so that it can also work for ostrees arrangements. | |
267 | ||
268 | * if a path ending in ".auto.d/" is set for RootDirectory=/RootImage= then do a | |
269 | strverscmp() of everything inside that dir and use that. i.e. implement very | |
270 | simple version control. Also use this in systemd-nspawn --image= and so on. | |
271 | ||
272 | * homed: while a home dir is not activated generate slightly different NSS | |
273 | records for it, that reports the home dir as "/" and the shell as some binary | |
274 | provided by us. Then, when an SSH login happens and SSH permits it our binary | |
275 | is invoked. This binary can then talk to homed and activate the homedir if | |
276 | it's not around yet, prompting the user for a password. Once that succeeded | |
277 | we'll switch to the real user record, i.e. home dir and shell, and our tool | |
278 | exec()s the latter. Net effect: ssh'ing into a homed account will just work: | |
279 | we'll neatly prompt for the homedir's password if its needed. –– Building on | |
280 | this we could take this even further: since this tool will potentially have | |
281 | access to the client's ssh-agent (if ssh-agent forwarding is enabled) we | |
282 | could implement SSH unlocking of a homedir with that: when enrolling a new | |
283 | ssh pubkey in a user record we'd ask the ssh-agent to sign some random value | |
284 | with the privkey, then use that as luks key to unlock the home dir. Will not | |
285 | work for ECDSA keys since their signatures contain a random component, but | |
286 | will work for RSA and Ed25519 keys. | |
287 | ||
bb5464ad LP |
288 | * add tiny service that decrypts encrypted user records passed via initrd |
289 | credential logic and drops them into /run where nss-systemd can pick them up, | |
290 | similar to /run/host/userdb/. Usecase: drop a root user JSON record there, | |
291 | and use it in the initrd to log in as root with locally selected password, | |
292 | for debugging purposes. | |
293 | ||
294 | * drop dependency on libcap, replace by direct syscalls based on | |
295 | CapabilityQuintet we already have. (This likely allows us drop drop libcap | |
296 | dep in the base OS image) | |
297 | ||
298 | * sysext: automatically activate sysext images dropped in via new sd-stub | |
299 | sysext pickup logic. | |
300 | ||
301 | * add concept for "exitrd" as inverse of "initrd", that we can transition to at | |
302 | shutdown, and has similar security semantics. This should then take the place | |
303 | of dracut's shutdown logic. Should probably support sysexts too. Care needs | |
304 | to be taken that the resulting logic ends up in RAM, i.e. is copied out of | |
305 | on-disk storage. | |
306 | ||
307 | * sd-stub: automatically pick up microcode from ESP and synthesize initrd from | |
308 | it, and measure it. Signing is not necessary, as microcode does that on its | |
309 | own. Pass as first initrd to kernel. | |
310 | ||
a07ab1dd LP |
311 | * userdbd: implement an additional varlink service socket that provides the |
312 | host user db in restricted form, then allow this to be bind mounted into | |
313 | sandboxed environments that want the host database in minimal form. All | |
314 | records would be stripped of all meta info, except the basic UID/name | |
315 | info. Then use this in portabled environments that do not use PrivateUsers=1. | |
316 | ||
a5bf435e LP |
317 | * logind introduce two types of sessions: "heavy" and "light". The former would |
318 | be our current sessions. But the latter would be a new type of session that | |
319 | is mostly the same but does not pull in user@.service or wait for it. Then, | |
320 | allow configuration which type of session is desired via pam_systemd | |
321 | parameters, and then make user@.service's session one of these "light" ones. | |
322 | People could then choose to make FTP sessions and suchlike "light" if they | |
323 | don't want the service manager to be started for that. | |
324 | ||
da3ab57c LP |
325 | * /etc/veritytab: allow that the roothash column can be specified as fs path |
326 | including a path to an AF_UNIX path, similar to how we do things with the | |
327 | keys of /etc/crypttab. That way people can store/provide the roothash | |
328 | externally and provide to us on demand only. | |
329 | ||
636c8a1f LP |
330 | * add high-level lockdown level for GPT dissection logic: e.g. an enum that can |
331 | be ANY (to mount anything), TRUSTED (to require that /usr is on signed | |
332 | verity, but rest doesn't matter), LOCKEDDOWN (to require that everything is | |
333 | on signed verity, except for ESP), SUPERLOCKDOWN (like LOCKEDDOWN but ESP not | |
334 | allowed). And then maybe some flavours of that that declare what is expected | |
335 | from home/srv/var… Then, add a new cmdline flag to all tools that parse such | |
336 | images, to configure this. Also, add a kernel cmdline option for this, to be | |
337 | honoured by the gpt auto generator. | |
338 | ||
339 | * nspawn: maybe optionally insert .nspawn file as GPT partition into images, so | |
340 | that such container images are entirely stand-alone and can be updated as | |
341 | one. | |
342 | ||
3fc0688d LP |
343 | * we probably should extend the root verity hash of the root fs into some PCR |
344 | on boot. (i.e. maybe add a crypttab option tpm2-measure=8 or so to measure it | |
345 | into PCR 8) | |
346 | ||
347 | * add a "policy" to the dissection logic. i.e. a bit mask what is OK to mount, | |
348 | what must be read-only, what requires encryption, and what requires | |
349 | authentication. | |
350 | ||
f4529c4d LP |
351 | * in uefi stub: query firmware regarding which PCRs are being used, store that |
352 | in EFI var. then use this when enrolling TPM2 in cryptsetup to verify that | |
353 | the selected PCRs actually are used by firmware. | |
354 | ||
322b3b38 LP |
355 | * rework recursive read-only remount to use new mount API |
356 | ||
63a185dc | 357 | * PAM: pick up authentication token from credentials |
9a6549f6 | 358 | |
9a6549f6 LP |
359 | * when mounting disk images: if IMAGE_ID/IMAGE_VERSION is set in os-release |
360 | data in the image, make sure the image filename actually matches this, so | |
361 | that images cannot be misused. | |
362 | ||
aca8ecc3 | 363 | * New udev block device symlink names: |
178d3ff2 | 364 | /dev/disk/by-parttypelabel/<pttype>-<ptlabel>. Use case: if pt label is used |
aca8ecc3 LP |
365 | as partition image version string, this is a safe way to reference a specific |
366 | version of a specific partition type, in particular where related partitions | |
367 | are processed (e.g. verity + rootfs both named "LennartOS_0.7"). | |
368 | ||
178d3ff2 LP |
369 | * sysupdate: |
370 | - add fuzzing to the pattern parser | |
371 | - support casync as download mechanism | |
372 | - direct TPM2 PCR change handling, possible renrolling LUKS2 media if needed. | |
373 | - "systemd-sysupdate update --all" support, that iterates through all components | |
374 | defined on the host, plus all images installed into /var/lib/machines/, | |
375 | /var/lib/portable/ and so on. | |
376 | - figure out what to do about system extensions (i.e. they need to imply an | |
377 | update component, since otherwise system extenion' sysupdate.d/ files would | |
378 | override the host's update files.) | |
379 | - Allow invocation with a single transfer definition, i.e. with | |
380 | --definitions= pointing to a file rather than a dir. | |
381 | - add ability to disable implicit decompression of downloaded artifacts, | |
382 | i.e. a Compress=no option in the transfer definitions | |
383 | ||
cf2ab2e7 LP |
384 | * in sd-id128: also parse UUIDs in RFC4122 URN syntax (i.e. chop off urn:uuid: prefix) |
385 | ||
31892e8d LP |
386 | * DynamicUser= + StateDirectory= → use uid mapping mounts, too, in order to |
387 | make dirs appear under right UID. | |
388 | ||
f3e58b55 LP |
389 | * systemd-sysext: optionally, run it in initrd already, before transitioning |
390 | into host, to open up possibility for services shipped like that. | |
391 | ||
49bd547b LP |
392 | * maybe add a tool that displays most recent journal logs as QR code to scan |
393 | off screen and run it automatically on boot failures, emergency logs and | |
394 | such. Use DRM APIs directly, see | |
395 | https://github.com/dvdhrm/docs/blob/master/drm-howto/modeset.c for an example | |
396 | for doing that. | |
397 | ||
398 | * pass systemd-detect-virt result to generators as env var. Modifying behaviour | |
399 | based on whether we are virtualized or not is a pretty common thing, hence | |
400 | maybe just pass that info along for free in an env var. We cache the result | |
401 | anyway, so it's basically free. | |
402 | ||
24063ba1 | 403 | * introduce /dev/disk/root/* symlinks that allow referencing partitions on the |
f3e58b55 LP |
404 | disk the rootfs is on in a reasonably secure way. (or maybe: add |
405 | /dev/gpt-auto-{home,srv,boot,…} similar in style to /dev/gpt-auto-root as we | |
406 | already have it. | |
24063ba1 | 407 | |
7ed72cfa LP |
408 | * whenever we receive fds via SCM_RIGHTS make sure none got dropped due to the |
409 | reception limit the kernel silently enforces. | |
410 | ||
66e52d22 LP |
411 | * add an Open= setting to service unit files that can open arbitrary file |
412 | system paths at service startup time and pass them to the service process via | |
413 | our usual socket activation protocol. If passed path refers to AF_UNIX | |
414 | socket: connect() to it. | |
415 | ||
416 | * add a ConnectSocket= setting to service unit files, that may reference a | |
417 | socket unit, and which will connect to the socket defined therein, and pass | |
418 | the resulting fd to the service program via socket activation proto. | |
419 | ||
420 | * Add a concept of ListenStream=anonymous to socket units: listen on a socket | |
421 | that is deleted in the fs. Usecase would be with ConnectSocket= above. | |
422 | ||
14f7d087 LP |
423 | * importd: support image signature verification with PKCS#7 + OpenBSD signify |
424 | logic, as alternative to crummy gpg | |
425 | ||
9786ba13 LP |
426 | * add "systemd-analyze debug" + AttachDebugger= in unit files: The former |
427 | specifies a command to execute; the latter specifies that an already running | |
428 | "systemd-analyze debug" instance shall be contacted and execution paused | |
429 | until it gives an OK. That way, tools like gdb or strace can be safely be | |
430 | invoked on processes forked off PID 1. | |
431 | ||
38abd1bf LP |
432 | * expose MS_NOSYMFOLLOW in various places |
433 | ||
199b097d LP |
434 | * make LoadCredential= automatically find credentials in /etc/creds, |
435 | /run/creds, … and so on, if path component is unqualified | |
436 | ||
437 | * teach LoadCredential=/LoadCredentialEncrypted= to load credentials from | |
438 | kernel cmdline, maybe: LoadCredentialEncrypted=foobar:proc-cmdline:foobar | |
439 | ||
440 | * credentials system: | |
441 | - acquire from kernel command line | |
442 | - acquire from EFI variable? | |
443 | - acquire via via ask-password? | |
444 | - acquire creds via keyring? | |
445 | - pass creds via keyring? | |
446 | - pass creds via memfd? | |
447 | - acquire + decrypt creds from pkcs11? | |
448 | - make systemd-cryptsetup acquire pw via creds logic | |
449 | - make PAMName= acquire pw via creds logic | |
450 | - make macsec/wireguard code in networkd read key via creds logic | |
451 | - make gatwayd/remote read key via creds logic | |
452 | - add sd_notify() command for flushing out creds not needed anymore | |
453 | ||
199b097d LP |
454 | * add tpm.target or so which is delayed until TPM2 device showed up in case |
455 | firmware indicates there is one. | |
07eabc2b | 456 | |
80670e74 LP |
457 | * Add concept for upgrading TPM2 enrollments, maybe a new switch |
458 | --pcrs=4:<hash> or so, i.e. select a PCR to include in the hash, and then | |
459 | override its hash | |
460 | ||
07eabc2b LB |
461 | * TPM2: auto-reenroll in cryptsetup, as fallback for hosed firmware upgrades |
462 | and such | |
463 | ||
464 | * introduce a new group to own TPM devices | |
80670e74 | 465 | |
80670e74 LP |
466 | * cryptsetup: if only recovery keys are registered and no regular passphrases, |
467 | ask user for "recovery key", not "passphrase" | |
468 | ||
469 | * cyptsetup: add option for automatically removing empty password slot on boot | |
470 | ||
7d7c75f1 | 471 | * cryptsetup: optionally, when run during boot-up and password is never |
80670e74 LP |
472 | entered, and we are on battery power (or so), power off machine again |
473 | ||
80670e74 LP |
474 | * cryptsetup: when waiting for FIDO2/PKCS#11 token, tell plymouth that, and |
475 | allow plymouth to abort the waiting and enter pw instead | |
7d7c75f1 | 476 | |
07eabc2b LB |
477 | * make cryptsetup lower --iter-time |
478 | ||
479 | * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a | |
480 | "base64:" prefix. Useful in particular for pkcs11 mode. | |
481 | ||
482 | * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use | |
483 | systemd-makefs.service instead. | |
484 | ||
485 | * cryptsetup: | |
486 | - cryptsetup-generator: allow specification of passwords in crypttab itself | |
487 | - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator | |
488 | ||
7d7c75f1 LP |
489 | * when configuring loopback netif, and it fails due to EPERM, eat up error if |
490 | it happens to be set up alright already. | |
491 | ||
492 | * at boot: check if battery above some threshold, if not power off again after explanation | |
493 | ||
494 | * userdb: add field for ambient caps, so that a user can have CAP_WAKE_ALARM | |
495 | for example. And add code that resets ambient caps for all services by | |
496 | default. | |
497 | ||
ff640bd2 LP |
498 | * sd-bus: when connecting to some dbus server socker, set originating AF_UNIX |
499 | socket name in abstract namespace to include "description" string, and pick | |
500 | it up from there in sd_bus_creds logic. i.e. we can use the socket peer | |
501 | address as conduit for some minimal connection metainfo, and use it to | |
502 | restore the "description" logic that kdbus used to have. | |
503 | ||
08d33656 | 504 | * systemd-analyze netif that explains predictable interface (or networkctl) |
d775d8e6 | 505 | |
816d460a LP |
506 | * Add service setting to run a service within the specified VRF. i.e. do the |
507 | equivalent of "ip vrf exec". | |
508 | ||
e59d030f LP |
509 | * change SwitchRoot() implementation in PID 1 to use pivot_root(".", "."), as |
510 | documented in the pivot_root(2) man page, so that we can drop the /oldroot | |
511 | temporary dir. | |
512 | ||
513 | * special case some calls of chase_symlinks() to use openat2() internally, so | |
514 | that the kernel does what we otherwise do. | |
515 | ||
6dbfbc46 LB |
516 | * add a new flag to chase_symlinks() that stops chasing once the first missing |
517 | component is found and then allows the caller to create the rest. | |
518 | ||
fc733bed LP |
519 | * make use of new glibc 2.32 APIs sigabbrev_np() and strerrorname_np(). |
520 | ||
effefa30 LP |
521 | * if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it |
522 | ||
42ba8d25 LP |
523 | * Remove any support for booting without /usr pre-mounted in the initrd entirely. |
524 | Update INITRD_INTERFACE.md accordingly. | |
525 | ||
f1eb0ccd LP |
526 | * pid1: Move to tracking of main pid/control pid of units per pidfd |
527 | ||
528 | * pid1: support new clone3() fork-into-cgroup feature | |
529 | ||
7cc8fb3e LP |
530 | * pid1: also remove PID files of a service when the service starts, not just |
531 | when it exits | |
532 | ||
cdfd8537 LP |
533 | * make us use dynamically fewer deps for containers in general purpose distros: |
534 | o turn into dlopen() deps: | |
cdfd8537 LP |
535 | - p11-kit-trust (always) |
536 | - kmod-libs (only when called from PID 1) | |
a52dc0b6 | 537 | - libblkid (only in RootImage= handling in PID 1, but not elsewhere) |
cdfd8537 LP |
538 | - libpam (only when called from PID 1) |
539 | - bzip2, xz, lz4 (always — gzip and zstd should probably stay static deps the way they are, | |
540 | since they are so basic and our defaults) | |
541 | o move into separate libsystemd-shared-iptables.so .so | |
542 | - iptables-libs (only used by nspawn + networkd) | |
543 | ||
77169ed0 LP |
544 | * seccomp: maybe use seccomp_merge() to merge our filters per-arch if we can. |
545 | Apparently kernel performance is much better with fewer larger seccomp | |
546 | filters than with more smaller seccomp filters. | |
547 | ||
bfafec25 LP |
548 | * systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum, |
549 | mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such | |
550 | ||
a6e1018d | 551 | * All tools that support --root= should also learn --image= so that they can |
612d3a68 LP |
552 | operate on disk images directly. Specifically: bootctl, systemctl, |
553 | coredumpctl. (Already done: systemd-nspawn, systemd-firstboot, | |
554 | systemd-repart, systemd-tmpfiles, systemd-sysusers, journalctl) | |
a6e1018d | 555 | |
112bed84 LP |
556 | * seccomp: by default mask x32 ABI system wide on x86-64. it's on its way out |
557 | ||
558 | * seccomp: don't install filters for ABIs that are masked anyway for the | |
559 | specific service | |
560 | ||
cbe952fe LP |
561 | * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it |
562 | exists and responds. | |
563 | ||
b47261e5 LP |
564 | * Maybe add a separate GPT partition type to the discoverable partition spec |
565 | for "hibernate" partitions, that are exactly like swap partitions but only | |
566 | activated right before hibernation and thus never used for regular swapping. | |
567 | ||
91fc013f | 568 | * socket units: allow creating a udev monitor socket with ListenDevices= or so, |
86b52a39 | 569 | with matches, then activate app through that passing socket over |
91fc013f | 570 | |
7e8facb3 | 571 | * unify on openssl: |
492f91d8 | 572 | - port journald + fsprg over from libgcrypt |
492f91d8 LP |
573 | - when that's done: kill gnutls support in resolved |
574 | ||
492f91d8 LP |
575 | * add growvol and makevol options for /etc/crypttab, similar to |
576 | x-systemd.growfs and x-systemd-makefs. | |
577 | ||
77b19caf LP |
578 | * userdb: allow username prefix searches in varlink API, allow realname and |
579 | realname substr searches in varlink API | |
006c44c1 | 580 | |
76410e98 LP |
581 | * userdb: allow uid/gid range checks |
582 | ||
2a4be3c5 | 583 | * userdb: allow existence checks |
006c44c1 | 584 | |
f1eb0ccd | 585 | * pid1: activation by journal search expression |
006c44c1 | 586 | |
492f91d8 LP |
587 | * when switching root from initrd to host, set the machine_id env var so that |
588 | if the host has no machine ID set yet we continue to use the random one the | |
589 | initrd had set. | |
590 | ||
173c7873 | 591 | * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to |
84a1ff94 | 592 | it for reaping assigned but unknown children. This needs to some special care |
173c7873 LP |
593 | to operate somewhat sensibly in light of priorities: P_ALL will return |
594 | arbitrary processes, regardless of the priority we want to watch them with, | |
595 | hence on each event loop iteration check all processes which we shall watch | |
596 | with higher prio explicitly, and then watch the entire rest with P_ALL. | |
597 | ||
598 | * tweak sd-event's child watching: keep a prioq of children to watch and use | |
599 | waitid() only on the children with the highest priority until one is waitable | |
600 | and ignore all lower-prio ones from that point on | |
601 | ||
173c7873 LP |
602 | * maybe introduce xattrs that can be set on the root dir of the root fs |
603 | partition that declare the volatility mode to use the image in. Previously I | |
604 | thought marking this via GPT partition flags but that's not ideal since | |
605 | that's outside of the LUKS encryption/verity verification, and we probably | |
606 | shouldn't operate in a volatile mode unless we got told so from a trusted | |
607 | source. | |
608 | ||
97e5cc88 LP |
609 | * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that |
610 | may be used to mark a whole binary as non-coredumpable. Would fix: | |
611 | https://bugs.freedesktop.org/show_bug.cgi?id=69447 | |
612 | ||
f3e361c1 LP |
613 | * teach parse_timestamp() timezones like the calendar spec already knows it |
614 | ||
9ef3376b LP |
615 | * beef up hibernation to optionally do swapon/swapoff immediately before/after |
616 | the hibernation | |
617 | ||
c846b233 LP |
618 | * beef up s2h to implement a battery watch loop: instead of entering |
619 | hibernation unconditionally after coming back from resume make a decision | |
620 | based on the battery load level: if battery level is above a specific | |
621 | threshold, go to suspend again, only hibernate if below it. This means we'd | |
622 | stick to suspend usually, but fall back to hibernation only when battery runs | |
623 | empty (well, subject to our sampling interval). Related to this, check if we | |
624 | can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too, | |
625 | i.e. see if it can wake up machines from suspend, so that we could resume | |
626 | automatically when the system is low on power and move automatically to | |
627 | hibernation mode. (see | |
628 | https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf | |
629 | section 10.2.2.8 and | |
630 | https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources | |
631 | at the end). | |
632 | ||
6fe23ff3 LB |
633 | * We should probably replace /etc/rc.d/README with a symlink to doc |
634 | content. After all it is constant vendor data. | |
9c230b8f | 635 | |
c6526b8d | 636 | * maybe add kernel cmdline params: to force random seed crediting |
312dc153 | 637 | |
ac5dca64 LP |
638 | * introduce a new per-process uuid, similar to the boot id, the machine id, the |
639 | invocation id, that is derived from process creds, specifically a hashed | |
640 | combination of AT_RANDOM + getpid() + the starttime from | |
641 | /proc/self/status. Then add these ids implicitly when logging. Deriving this | |
642 | uuid from these three things has the benefit that it can be derived easily | |
643 | from /proc/$PID/ in a stable, and unique way that changes on both fork() and | |
644 | exec(). | |
645 | ||
646 | * let's not GC a unit while its ratelimits are still pending | |
647 | ||
5daeeecf LP |
648 | * when killing due to service watchdog timeout maybe detect whether target |
649 | process is under ptracing and then log loudly and continue instead. | |
650 | ||
5802d977 LP |
651 | * make rfkill uaccess controllable by default, i.e. steal rule from |
652 | gnome-bluetooth and friends | |
653 | ||
03ccc7f0 LP |
654 | * make MAINPID= message reception checks even stricter: if service uses User=, |
655 | then check sending UID and ignore message if it doesn't match the user or | |
656 | root. | |
657 | ||
658 | * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device" | |
659 | is issued. | |
660 | ||
db3cea22 LP |
661 | * when importing an fs tree with machined, optionally apply userns-rec-chown |
662 | ||
663 | * when importing an fs tree with machined, complain if image is not an OS | |
664 | ||
707b3fbd LP |
665 | * Maybe introduce a helper safe_exec() or so, which is to execve() which |
666 | safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit | |
667 | to 1K implicitly, unless explicitly opted-out. | |
d7b659ef | 668 | |
d238709c | 669 | * rework seccomp/nnp logic that even if User= is used in combination with |
d96c081a LP |
670 | a seccomp option we don't have to set NNP. For that, change uid first whil |
671 | keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap. | |
672 | ||
8a7cf157 LP |
673 | * when no locale is configured, default to UEFI's PlatformLang variable |
674 | ||
d96c081a LP |
675 | * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and |
676 | usefaultd() and make systemd-analyze check for it. | |
677 | ||
06898123 | 678 | * paranoia: whenever we process passwords, call mlock() on the memory |
309c6b19 | 679 | first. i.e. look for all places we use free_and_erasep() and |
9ae4ef49 | 680 | augment them with mlock(). Also use MADV_DONTDUMP. |
8b213bf1 | 681 | Alternatively (preferably?) use memfd_secret(). |
06898123 | 682 | |
32875617 LP |
683 | * Move RestrictAddressFamily= to the new cgroup create socket |
684 | ||
685 | * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly | |
686 | patching around | |
687 | ||
76853293 LP |
688 | * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in |
689 | log.c and sd-journal-send | |
690 | ||
06898123 LP |
691 | * optionally: turn on cgroup delegation for per-session scope units |
692 | ||
d3aeddb8 LP |
693 | * introduce per-unit (i.e. per-slice, per-service) journal log size limits. |
694 | ||
42e18088 LP |
695 | * sd-boot: optionally, show boot menu when previous default boot item has |
696 | non-zero "tries done" count | |
697 | ||
8f2eb730 LP |
698 | * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which |
699 | contains some identifier for the project, which allows us to include | |
700 | clickable links to source files generating these log messages. The identifier | |
701 | could be some abberviated URL prefix or so (taking inspiration from Go | |
702 | imports). For example, for systemd we could use | |
703 | CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is | |
704 | sufficient to build a link by prefixing "http://" and suffixing the | |
705 | CODE_FILE. | |
706 | ||
8f2eb730 LP |
707 | * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can |
708 | make clickable links from log messages carrying a MESSAGE_ID, that lead to | |
709 | some explanatory text online. | |
710 | ||
7bd4bcf7 LP |
711 | * maybe extend .path units to expose fanotify() per-mount change events |
712 | ||
bb527e11 LP |
713 | * When reloading configuration PID 1 should reset all its properties to the |
714 | original defaults before calling parse_config() | |
715 | ||
c633b0a6 LP |
716 | * hibernate/s2h: make this robust and safe to enable in Fedora by default. |
717 | Specifically: | |
718 | ||
719 | 1. add resume_offset support to the resume code (i.e. support swap files | |
720 | properly) | |
e83419d0 | 721 | 2. check if swap is on weird storage and refuse if so |
46c41478 | 722 | 3. add auto-detection of hibernation images |
c633b0a6 | 723 | |
070d0ac9 LP |
724 | * cgroups: use inotify to get notified when somebody else modifies cgroups |
725 | owned by us, then log a friendly warning. | |
726 | ||
e44924f5 LP |
727 | * beef up log.c with support for stripping ANSI sequences from strings, so that |
728 | it is OK to include them in log strings. This would be particularly useful so | |
729 | that our log messages could contain clickable links for example for unit | |
730 | files and suchlike we operate on. | |
070d0ac9 | 731 | |
07eabc2b LB |
732 | * importd: add ability download images for portabled + sysext |
733 | ||
8c4c2dfc LP |
734 | * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration) |
735 | ||
8c4c2dfc LP |
736 | * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the |
737 | selected user is resolvable in the service even if it ships its own /etc/passwd) | |
738 | ||
5da19043 | 739 | * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the |
63a185dc | 740 | other doesn't. What a disaster. Probably to exclude it. |
5da19043 | 741 | |
16270697 LP |
742 | * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as |
743 | usually IN_ATTRIB is the right way to watch deleted files, as the former only | |
744 | fires when a file is actually removed from disk, i.e. the link count drops to | |
745 | zero and is not open anymore, while the latter happens when a file is | |
746 | unlinked from any dir. | |
747 | ||
bd1b3f75 | 748 | * port systemctl, busctl, … over to format-table.[ch]'s table formatters |
5da19043 | 749 | |
7bc756ff LP |
750 | * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up |
751 | ||
752 | * add --vacuum-xyz options to coredumpctl, matching those journalctl already has. | |
753 | ||
53c70a27 LP |
754 | * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all |
755 | files and directories that are left writable for a unit, and which are | |
756 | removed after the unit goes down again. A bit like --ephemeral for | |
757 | systemd-nspawn but for system services. If used together with RootImage= this | |
758 | should reflink the image file itself. | |
759 | ||
760 | Related: add Ephemeral=<path1> <path2> … which would allow marking | |
761 | specific paths only like this. | |
762 | ||
53c70a27 | 763 | * add CopyFile= or so as unit file setting that may be used to copy files or |
5238e957 | 764 | directory trees from the host to the services RootImage= and RootDirectory= |
53c70a27 LP |
765 | environment. Which we can use for /etc/machine-id and in particular |
766 | /etc/resolv.conf. Should be smart and do something useful on read-only | |
2aed63f4 | 767 | images, for example fall back to read-only bind mounting the file instead. |
53c70a27 | 768 | |
d9b50610 LP |
769 | * show invocation ID in systemd-run output |
770 | ||
771 | * bypass SIGTERM state in unit files if KillSignal is SIGKILL | |
772 | ||
9711b1ad LP |
773 | * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1 |
774 | and so on, which would mean we could report errors and such. | |
775 | ||
6b7b0f39 LP |
776 | * introduce DefaultSlice= or so in system.conf that allows changing where we |
777 | place our units by default, i.e. change system.slice to something | |
778 | else. Similar, ManagerSlice= should exist so that PID1's own scope unit could | |
779 | be moved somewhere else too. Finally machined and logind should get similar | |
780 | options so that it is possible to move user session scopes and machines to a | |
781 | different slice too by default. Usecase: people who want to put resources on | |
782 | the entire system, with the exception of one specific service. See: | |
783 | https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html | |
784 | ||
aa79f932 LP |
785 | * maybe rework get_user_creds() to query the user database if $SHELL is used |
786 | for root, but only then. | |
586a8e93 | 787 | |
46099c9e LP |
788 | * be stricter with fds we receive for the fdstore: close them asynchronously |
789 | ||
46099c9e LP |
790 | * calenderspec: add support for week numbers and day numbers within a |
791 | year. This would allow us to define "bi-weekly" triggers safely. | |
792 | ||
c3cd7cc9 LP |
793 | * sd-bus: add vtable flag, that may be used to request client creds implicitly |
794 | and asynchronously before dispatching the operation | |
795 | ||
d0e5db44 ZJS |
796 | * sd-bus: parse addresses given in sd_bus_set_addresses immediately and not |
797 | only when used. Add unit tests. | |
798 | ||
06345858 LP |
799 | * make use of ethtool veth peer info in machined, for automatically finding out |
800 | host-side interface pointing to the container. | |
801 | ||
48f1b5e5 LP |
802 | * add some special mode to LogsDirectory=/StateDirectory=… that allows |
803 | declaring these directories without necessarily pulling in deps for them, or | |
804 | creating them when starting up. That way, we could declare that | |
805 | systemd-journald writes to /var/log/journal, which could be useful when we | |
806 | doing disk usage calculations and so on. | |
807 | ||
899feb72 | 808 | * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char |
c6009ff0 | 809 | |
3d80d454 LP |
810 | * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for |
811 | the runtime dir as we maintain for the fdstore: i.e. keep it around as long | |
812 | as the unit is running or has a job queued. | |
813 | ||
5f7ecd61 | 814 | * support projid-based quota in machinectl for containers |
5962e9db | 815 | |
17b6f896 LP |
816 | * add a way to lock down cgroup migration: a boolean, which when set for a unit |
817 | makes sure the processes in it can never migrate out of it | |
818 | ||
17b6f896 LP |
819 | * blog about fd store and restartable services |
820 | ||
821 | * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document | |
822 | ||
370f9c21 LP |
823 | * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its |
824 | magic meaning and is no longer upgraded to something else if set explicitly. | |
825 | ||
17b6f896 LP |
826 | * in the long run: permit a system with /etc/machine-id linked to /dev/null, to |
827 | make it lose its identity, i.e. be anonymous. For this we'd have to patch | |
828 | through the whole tree to make all code deal with the case where no machine | |
829 | ID is available. | |
830 | ||
831 | * optionally, collect cgroup resource data, and store it in per-unit RRD files, | |
832 | suitable for processing with rrdtool. Add bus API to access this data, and | |
833 | possibly implement a CPULoad property based on it. | |
834 | ||
e7e4a258 LP |
835 | * beef up pam_systemd to take unit file settings such as cgroups properties as |
836 | parameters | |
837 | ||
63a185dc | 838 | * maybe hook up xfs/ext4 quotactl() with services? i.e. automatically manage |
d51c4fca | 839 | the quota of the user indicated in User= via unit file settings, like the |
5962e9db LP |
840 | other resource management concepts. Would mix nicely with DynamicUser=1. Or |
841 | alternatively, do this with projids, so that we can also cover services | |
842 | running as root. Quota should probably cover all the special dirs such as | |
843 | StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it | |
844 | is set, plus the whole disk space any image configured with RootImage=. | |
6fc373ee | 845 | |
9a92a97a LP |
846 | * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant |
847 | disks to see if the UID is already in use. | |
848 | ||
fa991fb7 LP |
849 | * expose IO accounting data on the bus, show it in systemd-run --wait and log |
850 | about it in the resource log message | |
851 | ||
d73b607d LP |
852 | * Add AddUser= setting to unit files, similar to DynamicUser=1 which however |
853 | creates a static, persistent user rather than a dynamic, transient user. We | |
854 | can leverage code from sysusers.d for this. | |
855 | ||
fd63f36c LP |
856 | * add some optional flag to ReadWritePaths= and friends, that has the effect |
857 | that we create the dir in question when the service is started. Example: | |
858 | ||
859 | ReadWritePaths=:/var/lib/foobar | |
860 | ||
f59d1da8 LP |
861 | * Add ExecMonitor= setting. May be used multiple times. Forks off a process in |
862 | the service cgroup, which is supposed to monitor the service, and when it | |
863 | exits the service is considered failed by its monitor. | |
864 | ||
33bac67b LP |
865 | * track the per-service PAM process properly (i.e. as an additional control |
866 | process), so that it may be queried on the bus and everything. | |
867 | ||
868 | * add a new "debug" job mode, that is propagated to unit_start() and for | |
869 | services results in two things: we raise SIGSTOP right before invoking | |
870 | execve() and turn off watchdog support. Then, use that to implement | |
871 | "systemd-gdb" for attaching to the start-up of any system service in its | |
872 | natural habitat. | |
873 | ||
8eb7383b LP |
874 | * 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 |
875 | ||
b5bdbcd5 LP |
876 | * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and |
877 | then use that for the setting used in user@.service. It should be understood | |
878 | relative to the configured default value. | |
879 | ||
d21494ea LP |
880 | * enable LockMLOCK to take a percentage value relative to physical memory |
881 | ||
04397464 | 882 | * Permit masking specific netlink APIs with RestrictAddressFamily= |
d82047be | 883 | |
d82047be LP |
884 | * define gpt header bits to select volatility mode |
885 | ||
42d61ded LP |
886 | * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc |
887 | ||
04397464 | 888 | * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away) |
42d61ded | 889 | |
04397464 | 890 | * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave) |
563a69f4 | 891 | |
04397464 | 892 | * ProtectKeyRing= to take keyring calls away |
2c5f2958 | 893 | |
8ce9b83a | 894 | * RemoveKeyRing= to remove all keyring entries of the specified user |
a46eac1b LP |
895 | |
896 | * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill | |
897 | on PID 1 with the relevant signals, and makes relevant files in /sys and | |
898 | /proc (such as the sysrq stuff) unavailable | |
899 | ||
88511a37 LB |
900 | * Support ReadWritePaths/ReadOnlyPaths/InaccessiblePaths in systemd --user instances |
901 | via the new unprivileged Landlock LSM (https://landlock.io) | |
902 | ||
e40a326c | 903 | * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things |
89f193fa | 904 | |
8ce9b83a LP |
905 | * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set, |
906 | find a way to map the User=/Group= of the service to the right name. This way | |
907 | a user/group for a service only has to exist on the host for the right | |
908 | mapping to work. | |
909 | ||
2c5f2958 LP |
910 | * add bus API for creating unit files in /etc, reusing the code for transient units |
911 | ||
912 | * add bus API to remove unit files from /etc | |
913 | ||
914 | * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only) | |
915 | ||
b8c7afdf LP |
916 | * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the |
917 | kernel doesn't support linkat() that replaces existing files, currently) | |
918 | ||
1e555cb5 LP |
919 | * transient units: don't bother with actually setting unit properties, we |
920 | reload the unit file anyway | |
921 | ||
c8048350 LP |
922 | * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown |
923 | ||
3d39e6e5 LP |
924 | * cache sd_event_now() result from before the first iteration... |
925 | ||
bd098bce LP |
926 | * PID1: find a way how we can reload unit file configuration for |
927 | specific units only, without reloading the whole of systemd | |
928 | ||
f9bf1b8f | 929 | * add an explicit parser for LimitRTPRIO= that verifies |
de7399eb | 930 | the specified range and generates sane error messages for incorrect |
f9bf1b8f | 931 | specifications. |
de7399eb | 932 | |
3efc8c72 LP |
933 | * when we detect that there are waiting jobs but no running jobs, do something |
934 | ||
e6a26d8c LP |
935 | * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn) |
936 | ||
a2088fd0 | 937 | * there's probably something wrong with having user mounts below /sys, |
5238e957 | 938 | as we have for debugfs. for example, src/core/mount.c handles mounts |
a2088fd0 LP |
939 | prefixed with /sys generally special. |
940 | http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html | |
941 | ||
8aa20381 LP |
942 | * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline |
943 | ||
a7972611 ZJS |
944 | * initrd-parse-etc.service: can we skip daemon-reload if /sysroot/etc/fstab is missing? |
945 | Note that we start initrd-fs.target and initrd-cleanup.target there, so a straightforward | |
946 | ConditionPathExists= is not enough. | |
947 | ||
931bc195 | 948 | * docs: bring https://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date |
b18d23d7 | 949 | |
60d17b74 LP |
950 | * add a job mode that will fail if a transaction would mean stopping |
951 | running units. Use this in timedated to manage the NTP service | |
952 | state. | |
953 | http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html | |
954 | ||
477e75ef LP |
955 | * The udev blkid built-in should expose a property that reflects |
956 | whether media was sensed in USB CF/SD card readers. This should then | |
957 | be used to control SYSTEMD_READY=1/0 so that USB card readers aren't | |
958 | picked up by systemd unless they contain a medium. This would mirror | |
959 | the behaviour we already have for CD drives. | |
960 | ||
c3a0d00d LP |
961 | * hostnamectl: show root image uuid |
962 | ||
d2f81fb0 LP |
963 | * Find a solution for SMACK capabilities stuff: |
964 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html | |
98cd2651 | 965 | |
0a86c1a9 LP |
966 | * synchronize console access with BSD locks: |
967 | http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html | |
968 | ||
e031c227 | 969 | * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads: |
0a86c1a9 LP |
970 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html |
971 | ||
8514b677 LP |
972 | * figure out when we can use the coarse timers |
973 | ||
8483d73f LP |
974 | * maybe allow timer units with an empty Units= setting, so that they |
975 | can be used for resuming the system but nothing else. | |
976 | ||
25e773ee | 977 | * what to do about udev db binary stability for apps? (raw access is not an option) |
b857e042 | 978 | |
720652b3 | 979 | * exponential backoff in timesyncd when we cannot reach a server |
42aeb14a | 980 | |
720652b3 | 981 | * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM |
e25b5a8d | 982 | |
563b1bdc LP |
983 | * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share.... |
984 | ||
6bd7941e TG |
985 | * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL |
986 | (throughout the codebase, not only PID1) | |
987 | ||
07eabc2b LB |
988 | * drop nss-myhostname in favour of nss-resolve? |
989 | ||
9d6db739 | 990 | * resolved: |
9d6db739 | 991 | - mDNS/DNS-SD |
ccc3e8a1 LP |
992 | - service registration |
993 | - service/domain/types browsing | |
0f47ed0a | 994 | - avahi compat |
9d6db739 | 995 | - DNS-SD service registration from socket units |
e25b5a8d DH |
996 | - resolved should optionally register additional per-interface LLMNR |
997 | names, so that for the container case we can establish the same name | |
998 | (maybe "host") for referencing the server, everywhere. | |
720652b3 | 999 | - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?) |
3efb871a | 1000 | - hook up resolved with machined-based address resolution |
3f77a1b1 | 1001 | |
e25b5a8d | 1002 | * refcounting in sd-resolve is borked |
e2a69298 | 1003 | |
a940778f LP |
1004 | * add new gpt type for btrfs volumes |
1005 | ||
3de03738 LP |
1006 | * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them. |
1007 | ||
37efac5d LP |
1008 | * a way for container managers to turn off getty starting via $container_headless= or so... |
1009 | ||
7348b3ad LP |
1010 | * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit |
1011 | ||
81429136 KS |
1012 | * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services |
1013 | they run added to the initial transaction and thus confuse Type=idle. | |
e107ed18 | 1014 | |
edb2935c LP |
1015 | * add bus api to query unit file's X fields. |
1016 | ||
6a3f892a | 1017 | * gpt-auto-generator: |
2a781fc9 | 1018 | - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap? |
6a3f892a | 1019 | - Make /home automount rather than mount? |
6a3f892a | 1020 | |
65026403 LP |
1021 | * add generator that pulls in systemd-network from containers when |
1022 | CAP_NET_ADMIN is set, more than the loopback device is defined, even | |
1023 | when it is otherwise off | |
f8901862 | 1024 | |
f9bf1b8f | 1025 | * MessageQueueMessageSize= (and suchlike) should use parse_iec_size(). |
eda8f067 | 1026 | |
af1082b0 LP |
1027 | * implement Distribute= in socket units to allow running multiple |
1028 | service instances processing the listening socket, and open this up | |
1029 | for ReusePort= | |
1030 | ||
f38afcd0 | 1031 | * cgroups: |
f38afcd0 | 1032 | - implement per-slice CPUFairScheduling=1 switch |
f38afcd0 LP |
1033 | - introduce high-level settings for RT budget, swappiness |
1034 | - how to reset dynamically changed unit cgroup attributes sanely? | |
1035 | - when reloading configuration, apply new cgroup configuration | |
1036 | - when recursively showing the cgroup hierarchy, optionally also show | |
1037 | the hierarchies of child processes | |
0bee65f0 | 1038 | |
f38afcd0 | 1039 | * transient units: |
f38afcd0 | 1040 | - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt |
ebcf1f97 | 1041 | |
718db961 LP |
1042 | * when we detect low battery and no AC on boot, show pretty splash and refuse boot |
1043 | ||
718db961 LP |
1044 | * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops |
1045 | ||
966204e0 LP |
1046 | * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1 |
1047 | ||
41644622 LP |
1048 | * 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 |
1049 | ||
7f79cd71 | 1050 | * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs |
0aafd43d | 1051 | |
19aadacf JE |
1052 | * If we try to find a unit via a dangling symlink, generate a clean |
1053 | error. Currently, we just ignore it and read the unit from the search | |
df5f6971 LP |
1054 | path anyway. |
1055 | ||
04397464 | 1056 | * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up |
fcba531e | 1057 | |
bdeeb6b5 LP |
1058 | * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted. |
1059 | ||
1060 | * load .d/*.conf dropins for device units | |
1061 | ||
07eabc2b | 1062 | * There's currently no way to cancel fsck (used to be possible via C-c or c on the console) |
f38afcd0 | 1063 | |
07eabc2b | 1064 | * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/ |
eb01ba5d | 1065 | |
07eabc2b LB |
1066 | * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early |
1067 | ||
1068 | * verify that the AF_UNIX sockets of a service in the fs still exist | |
1069 | when we start a service in order to avoid confusion when a user | |
1070 | assumes starting a service is enough to make it accessible | |
1071 | ||
1072 | * Make it possible to set the keymap independently from the font on | |
1073 | the kernel cmdline. Right now setting one resets also the other. | |
1074 | ||
1075 | * and a dbus call to generate target from current state | |
1076 | ||
1077 | * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support. | |
1078 | ||
1079 | * dot output for --test showing the 'initial transaction' | |
1080 | ||
1081 | * be able to specify a forced restart of service A where service B depends on, in case B | |
1082 | needs to be auto-respawned? | |
1083 | ||
1084 | * pid1: | |
1085 | - When logging about multiple units (stopping BoundTo units, conflicts, etc.), | |
1086 | log both units as UNIT=, so that journalctl -u triggers on both. | |
1087 | - generate better errors when people try to set transient properties | |
1088 | that are not supported... | |

1090 | - maybe introduce WantsMountsFor=? Usecase: | |
1091 | http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html | |
1092 | - recreate systemd's D-Bus private socket file on SIGUSR2 | |
1093 | - move PAM code into its own binary | |
1094 | - when we automatically restart a service, ensure we restart its rdeps, too. | |
1095 | - hide PAM options in fragment parser when compile time disabled | |
1096 | - Support --test based on current system state | |
1097 | - 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(). | |
1098 | - after deserializing sockets in socket.c we should reapply sockopts and things | |
1099 | - drop PID 1 reloading, only do reexecing (difficult: Reload() | |
1100 | currently is properly synchronous, Reexec() is weird, because we | |
1101 | cannot delay the response properly until we are back, so instead of | |
1102 | being properly synchronous we just keep open the fd and close it | |
1103 | when done. That means clients do not get a successful method reply, | |
1104 | but much rather a disconnect on success. | |
1105 | - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr | |
1106 | - when a bus name of a service disappears from the bus make sure to queue further activation requests | |
1107 | - maybe introduce CoreScheduling=yes/no to optionally set a PR_SCHED_CORE cookie, so that all | |
1108 | processes in a service's cgroup share the same cookie and are guaranteed not to share SMT cores | |
1109 | with other units https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/admin-guide/hw-vuln/core-scheduling.rst | |
1110 | ||
1111 | * unit files: | |
1112 | - allow port=0 in .socket units | |
1113 | - maybe introduce ExecRestartPre= | |
1114 | - add ReloadSignal= for configuring a reload signal to use | |
1115 | - implement Register= switch in .socket units to enable registration | |
1116 | in Avahi, RPC and other socket registration services. | |
1117 | - allow Type=simple with PIDFile= | |
1118 | https://bugzilla.redhat.com/show_bug.cgi?id=723942 | |
1119 | - allow writing multiple conditions in unit files on one line | |
1120 | - introduce Type=pid-file | |
1121 | - add a concept of RemainAfterExit= to scope units | |
1122 | - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely | |
1123 | - add verification of [Install] section to systemd-analyze verify | |
1124 | ||
1125 | * timer units: | |
63a185dc | 1126 | - timer units should get the ability to trigger when DST changes |
07eabc2b LB |
1127 | - Modulate timer frequency based on battery state |
1128 | ||
1129 | * add libsystemd-password or so to query passwords during boot using the password agent logic | |
1130 | ||
1131 | * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed | |
1132 | ||
1133 | * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel | |
1134 | ||
1135 | * make repeated alt-ctrl-del presses printing a dump | |
1136 | ||
07eabc2b | 1137 | * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not |
461bd8e4 | 1138 | |
ab8e074c LP |
1139 | * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login. |
1140 | ||
1141 | * add a pam module that on password changes updates any LUKS slot where the password matches | |
1142 | ||
fff87a35 | 1143 | * test/: |
20d52ab6 | 1144 | - add unit tests for config_parse_device_allow() |
b8b4d3dd | 1145 | |
b5c03638 | 1146 | * seems that when we follow symlinks to units we prefer the symlink |
d28315e4 | 1147 | destination path over /etc and /usr. We should not do that. Instead |
b5c03638 LP |
1148 | /etc should always override /run+/usr and also any symlink |
1149 | destination. | |
1150 | ||
eece8c6f LP |
1151 | * when isolating, try to figure out a way how we implicitly can order |
1152 | all units we stop before the isolating unit... | |
1153 | ||
356ce991 LP |
1154 | * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off}) |
1155 | ||
6daebf9e ZJS |
1156 | * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add |
1157 | ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at | |
1158 | https://github.com/systemd/systemd/pull/15109#issuecomment-607740136. | |
1159 | ||
1ccfb792 LP |
1160 | * BootLoaderSpec: Define a way how an installer can figure out whether a BLS |
1161 | compliant boot loader is installed. | |
795607b2 | 1162 | |
0be8342c LP |
1163 | * think about requeuing jobs when daemon-reload is issued? usecase: |
1164 | the initrd issues a reload after fstab from the host is accessible | |
1165 | and we might want to requeue the mounts local-fs acquired through | |
1166 | that automatically. | |
1167 | ||
e5ec62c5 | 1168 | * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep() |
54c31a79 | 1169 | |
ccddd104 | 1170 | * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good |
826872b6 | 1171 | |
3679d112 LP |
1172 | * shutdown logging: store to EFI var, and store to USB stick? |
1173 | ||
356ce991 | 1174 | * merge unit_kill_common() and unit_kill_context() |
490b7e47 | 1175 | |
07eabc2b LB |
1176 | * add a dependency on standard-conf.xml and other included files to man pages |
1177 | ||
1178 | * MountFlags=shared acts as MountFlags=slave right now. | |
1179 | ||
1180 | * properly handle loop back mounts via fstab, especially regards to fsck/passno | |
1181 | ||
1182 | * initialize the hostname from the fs label of /, if /etc/hostname does not exist? | |
1183 | ||
1184 | * sd-bus: | |
1185 | - EBADSLT handling | |
1186 | - GetAllProperties() on a non-existing object does not result in a failure currently | |
1187 | - port to sd-resolve for connecting to TCP dbus servers | |
1188 | - 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 | |
1189 | - see if we can drop more message validation on the sending side | |
1190 | - add API to clone sd_bus_message objects | |
1191 | - longer term: priority inheritance | |
1192 | - dbus spec updates: | |
1193 | - NameLost/NameAcquired obsolete | |
1194 | - GVariant | |
1195 | - path escaping | |
1196 | - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now | |
1197 | ||
1198 | * sd-event | |
1199 | - allow multiple signal handlers per signal? | |
1200 | - document chaining of signal handler for SIGCHLD and child handlers | |
1201 | - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ... | |
1202 | - maybe support iouring as backend, so that we allow hooking read and write | |
1203 | operations instead of IO ready events into event loops. See considerations | |
1204 | here: | |
1205 | http://blog.vmsplice.net/2020/07/rethinking-event-loop-integration-for.html | |
1206 | ||
1207 | * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we | |
1208 | should be able to safely try another attempt when the bus call LoadUnit() is invoked. | |
1209 | ||
1210 | * maybe do not install getty@tty1.service symlink in /etc but in /usr? | |
1211 | ||
1212 | * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word | |
1213 | ||
1214 | * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units. | |
1215 | ||
1216 | * firstboot: allow provisioning of /etc/hosts entries, so that we can via the | |
1217 | credentials logic insert host name to resolve into containers/hosts. Usecase: | |
1218 | fork a container, and make it ping some specific address which is defined by | |
1219 | the host on invocation | |
1220 | ||
1221 | * systemd-firstboot: make sure to always use chase_symlinks() before | |
1222 | reading/writing files | |
1223 | ||
1224 | * 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 | |
1225 | ||
1226 | * sd-boot: define a drop-in dir in the ESP that may contain X.509 | |
1227 | certificates. If the firmware is detected to be in setup mode, automatically | |
1228 | enroll them as PK/KEK/db, turn off setup mode and proceed. Optionally, | |
1229 | instead of auto-enrolling them add them to the sd-boot menu, giving the user | |
1230 | the option to manually enroll them, after selecting the menu entry. This way, | |
1231 | installer images can just drop the certfiicates in the ESP, and on first boot | |
1232 | can easily enroll the keys without ever booting up. | |
1233 | ||
1234 | * efi stub: optionally, load initrd from disk as a separate file, HMAC check it | |
1235 | with key from TPM, bound to PCR, refusing if failing. This would then allow | |
1236 | traditional distros that generate initrds locally to secure them with TPM: | |
1237 | after generating the initrd, do the HMAC calculation, put result in initrd | |
1238 | filename, done. This would then bind the validity of the initrd to the local | |
1239 | host, and used kernel, and means people cannot change initrd or kernel | |
1240 | without booting the kernel + initrd. | |
1241 | ||
b44be3ec | 1242 | * EFI: |
b44be3ec LP |
1243 | - honor language efi variables for default language selection (if there are any?) |
1244 | - honor timezone efi variables for default timezone selection (if there are any?) | |
466784c8 | 1245 | - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables |
631427d6 | 1246 | * bootctl |
631427d6 | 1247 | - recognize the case when not booted on EFI |
e4181484 | 1248 | |
07eabc2b | 1249 | * bootctl,sd-boot: actually honour the "architecture" key |
e9fd44b7 | 1250 | |
07eabc2b LB |
1251 | * bootctl: |
1252 | - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation | |
1253 | - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host | |
1254 | - make it operate on loopback files, dissecting enough to find ESP to operate on | |
f620a368 LP |
1255 | - bootspec: properly support boot attempt counters when parsing entry file names |
1256 | ||
1257 | * kernel-install: | |
1258 | - optionally, support generating type #2 entries instead of type #1, including signing them | |
e6c6e7af | 1259 | |
b44be3ec LP |
1260 | * logind: |
1261 | - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around | |
b44be3ec LP |
1262 | - logind: wakelock/opportunistic suspend support |
1263 | - Add pretty name for seats in logind | |
1264 | - logind: allow showing logout dialog from system? | |
f38afcd0 LP |
1265 | - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly. |
1266 | - if pam_systemd is invoked by su from a process that is outside of a | |
1267 | any session we should probably just become a NOP, since that's | |
1268 | usually not a real user session but just some system code that just | |
1269 | needs setuid(). | |
279f0366 LP |
1270 | - logind: make the Suspend()/Hibernate() bus calls wait for the for |
1271 | the job to be completed. before returning, so that clients can wait | |
1272 | for "systemctl suspend" to finish to know when the suspending is | |
1273 | complete. | |
1274 | - logind: when the power button is pressed short, just popup a | |
1275 | logout dialog. If it is pressed for 1s, do the usual | |
1276 | shutdown. Inspiration are Macs here. | |
28423d9a | 1277 | - expose "Locked" property on logind session objects |
e25b5a8d DH |
1278 | - maybe allow configuration of the StopTimeout for session scopes |
1279 | - rename session scope so that it includes the UID. THat way | |
1280 | the session scope can be arranged freely in slices and we don't have | |
1281 | make assumptions about their slice anymore. | |
1282 | - follow PropertiesChanged state more closely, to deal with quick logouts and | |
1283 | relogins | |
77b19caf | 1284 | - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set |
e673ad04 | 1285 | |
07eabc2b LB |
1286 | * move logind udev rules to top-level rule.d/ directory |
1287 | ||
1288 | * move multiseat vid/pid matches from logind udev rule to hwdb | |
1289 | ||
1290 | * logind: rework pam_logind to also do a bus call in case of invocation from | |
1291 | user@.service, which returns the XDG_RUNTIME_DIR value, and make this | |
1292 | behaviour selectable via pam module option. | |
1293 | ||
1294 | * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it | |
1295 | in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle | |
1296 | ||
b44be3ec | 1297 | * journal: |
57f2a947 | 1298 | - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields |
b44be3ec LP |
1299 | - journald: also get thread ID from client, plus thread name |
1300 | - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups | |
1301 | - add API to close/reopen/get fd for journal client fd in libsystemd-journal. | |
2aed63f4 | 1302 | - fall back to /dev/log based logging in libsystemd-journal, if we cannot log natively? |
b44be3ec | 1303 | - declare the local journal protocol stable in the wiki interface chart |
b44be3ec LP |
1304 | - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg |
1305 | - journald: when dropping msgs due to ratelimit make sure to write | |
1306 | "dropped %u messages" not only when we are about to print the next | |
5238e957 | 1307 | message that works, but already after a short timeout |
b44be3ec LP |
1308 | - check if we can make journalctl by default use --follow mode inside of less if called without args? |
1309 | - maybe add API to send pairs of iovecs via sd_journal_send | |
f47ec8eb | 1310 | - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access |
b44be3ec LP |
1311 | - journactl: support negative filtering, i.e. FOOBAR!="waldo", |
1312 | and !FOOBAR for events without FOOBAR. | |
06847d0f | 1313 | - journal: store timestamp of journal_file_set_offline() in the header, |
038cf334 | 1314 | so it is possible to display when the file was last synced. |
b44be3ec LP |
1315 | - 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. |
1316 | - journal: find a way to allow dropping history early, based on priority, other rules | |
1317 | - journal: When used on NFS, check payload hashes | |
b44be3ec LP |
1318 | - journald: add kernel cmdline option to disable ratelimiting for debug purposes |
1319 | - refuse taking lower-case variable names in sd_journal_send() and friends. | |
1320 | - journald: we currently rotate only after MaxUse+MaxFilesize has been reached. | |
1321 | - journal: deal nicely with byte-by-byte copied files, especially regards header | |
b44be3ec | 1322 | - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit |
601d9d6f | 1323 | - Replace utmp, wtmp, btmp, and lastlog completely with journal |
f38afcd0 | 1324 | - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax? |
f38afcd0 LP |
1325 | - when a kernel driver logs in a tight loop, we should ratelimit that too. |
1326 | - journald: optionally, log debug messages to /run but everything else to /var | |
1327 | - journald: when we drop syslog messages because the syslog socket is | |
1328 | full, make sure to write how many messages are lost as first thing | |
1329 | to syslog when it works again. | |
279f0366 LP |
1330 | - journald: allow per-priority and per-service retention times when rotating/vacuuming |
1331 | - journald: make use of uid-range.h to managed uid ranges to split | |
1332 | journals in. | |
1333 | - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so... | |
1334 | - improve journalctl performance by loading journal files | |
1335 | lazily. Encode just enough information in the file name, so that we | |
1336 | do not have to open it to know that it is not interesting for us, for | |
1337 | the most common operations. | |
e25b5a8d | 1338 | - man: document that corrupted journal files is nothing to act on |
e25b5a8d DH |
1339 | - rework journald sigbus stuff to use mutex |
1340 | - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our | |
1341 | services that run under their own user ids, and use User= (but only | |
1342 | in a world where userns is ubiquitous since otherwise we cannot | |
1343 | invoke those daemons on the host AND in a container anymore). Also, | |
1344 | if LimitNPROC= is used without User= we should warn and refuse | |
1345 | operation. | |
1346 | - journalctl --verify: don't show files that are currently being | |
1347 | written to as FAIL, but instead show that their are being written to. | |
1348 | - add journalctl -H that talks via ssh to a remote peer and passes through | |
1349 | binary logs data | |
e25b5a8d | 1350 | - add a version of --merge which also merges /var/log/journal/remote |
e25b5a8d DH |
1351 | - journalctl: -m should access container journals directly by enumerating |
1352 | them via machined, and also watch containers coming and going. | |
1353 | Benefit: nspawn --ephemeral would start working nicely with the journal. | |
1354 | - assign MESSAGE_ID to log messages about failed services | |
06847d0f | 1355 | - check if loop in decompress_blob_xz() is necessary |
b44be3ec | 1356 | |
07eabc2b LB |
1357 | * journald: support RFC3164 fully for the incoming syslog transport, see |
1358 | https://github.com/systemd/systemd/issues/19251#issuecomment-816601955 | |
1359 | ||
1360 | * Hook up journald's FSS logic with TPM2: seal the verification disk by | |
1361 | time-based policy, so that the verification key can remain on host and ve | |
1362 | validated via TPM. | |
1363 | ||
1364 | * build short web pages out of each catalog entry, build them along with man | |
1365 | pages, and include hyperlinks to them in the journal output | |
1366 | ||
1367 | * journald: do journal file writing out-of-process, with one writer process per | |
1368 | client UID, so that synthetic hash table collisions can slow down a specific | |
1369 | user's journal stream down but not the others. | |
1370 | ||
1371 | * tweak journald context caching. In addition to caching per-process attributes | |
1372 | keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read) | |
1373 | keyed by cgroup path, and guarded by ctime changes. This should provide us | |
1374 | with a nice speed-up on services that have many processes running in the same | |
1375 | cgroup. | |
1376 | ||
1377 | * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for | |
1378 | the sd-journal logging socket, and, if the timeout is set to 0, sets | |
1379 | O_NONBLOCK on it. That way people can control if and when to block for | |
1380 | logging. | |
1381 | ||
1382 | * journalctl: make sure -f ends when the container indicated by -M terminates | |
1383 | ||
1384 | * journald: sigbus API via a signal-handler safe function that people may call | |
1385 | from the SIGBUS handler | |
1386 | ||
590171d1 ZJS |
1387 | * add a test if all entries in the catalog are properly formatted. |
1388 | (Adding dashes in a catalog entry currently results in the catalog entry | |
1389 | being silently skipped. journalctl --update-catalog must warn about this, | |
1390 | and we should also have a unit test to check that all our message are OK.) | |
1391 | ||
07eabc2b LB |
1392 | * homed: |
1393 | - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth | |
1394 | - rollback when resize fails mid-operation | |
1395 | - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid) | |
07eabc2b LB |
1396 | - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device. |
1397 | - create on activate? | |
1398 | - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls? | |
1399 | - communicate clearly when usb stick is safe to remove. probably involves | |
1400 | beefing up logind to make pam session close hook synchronous and wait until | |
1401 | systemd --user is shut down. | |
1402 | - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service | |
1403 | - maybe make automatic, read-only, time-based reflink-copies of LUKS disk | |
1404 | images (and btrfs snapshots of subvolumes) (think: time machine) | |
1405 | - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory) | |
1406 | - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work | |
1407 | - fingerprint authentication, pattern authentication, … | |
1408 | - make sure "classic" user records can also be managed by homed | |
1409 | - make size of $XDG_RUNTIME_DIR configurable in user record | |
1410 | - query password from kernel keyring first | |
1411 | - update even if record is "absent" | |
07eabc2b LB |
1412 | - move acct mgmt stuff from pam_systemd_home to pam_systemd? |
1413 | - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for | |
1414 | - make slice for users configurable (requires logind rework) | |
1415 | - logind: populate auto-login list bus property from PKCS#11 token | |
1416 | - when determining state of a LUKS home directory, check DM suspended sysfs file | |
a11e7c0b LB |
1417 | - when homed is in use, maybe start the user session manager in a mount namespace with MS_SLAVE, |
1418 | so that mounts propagate down but not up - eg, user A setting up a backup volume | |
1419 | doesn't mean user B sees it | |
9c53de8b | 1420 | - use credentials logic/TPM2 logic to store homed signing key |
9c53de8b LP |
1421 | - permit multiple user record signing keys to be used locally, and pick |
1422 | the right one for signing records automatically depending on a pre-existing | |
1423 | signature | |
1424 | - add a way to "adopt" a home directory, i.e. strip foreign signatures | |
1425 | and insert a local signature instead. | |
1426 | - as an extension to the directory+subvolume backend: if located on | |
1427 | especially marked fs, then sync down password into LUKS header of that fs, | |
1428 | and always verify passwords against it too. Bootstrapping is a problem | |
1429 | though: if no one is logged in (or no other user even exists yet), how do you | |
1430 | unlock the volume in order to create the first user and add the first pw. | |
1431 | - support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt | |
1432 | - maybe pre-create ~/.cache as subvol so that it can have separate quota | |
1433 | easily? | |
9c53de8b LP |
1434 | - add a switch to homectl (maybe called --first-boot) where it will check if |
1435 | any non-system users exist, and if not prompts interactively for basic user | |
1436 | info, mimicking systemd-firstboot. Then, place this in a service that runs | |
1437 | after systemd-homed, but before gdm and friends, as a simple, barebones | |
1438 | fallback logic to get a regular user created on uninitialized systems. | |
1439 | - store PKCS#11 + FIDO2 token info in LUKS2 header, compatible with | |
1440 | systemd-cryptsetup, so that it can unlock homed volumes | |
6d975fe7 LP |
1441 | - maybe make all *.home files owned by `systemd-home` user or so, so that we |
1442 | can easily set overall quota for all users | |
1443 | - on login, if we can't fallocate initially, but rebalance is on, then allow | |
1444 | login in discard mode, then immediately rebalance, then turn off discard | |
f1a147f2 | 1445 | - extend user records with optional "bulk" data. Specifically, a user |
288bd406 | 1446 | avatar/photo or so. This data should be stored along with the user record, |
f1a147f2 LP |
1447 | but probably shouldn't be part of the record itself, since it might be |
1448 | large. | |
07eabc2b | 1449 | |
07eabc2b LB |
1450 | * add a new switch --auto-definitions=yes/no or so to systemd-repart. If |
1451 | specified, synthesize a definition automatically if we can: enlarge last | |
1452 | partition on disk, but only if it is marked for growing and not read-only. | |
1453 | ||
1454 | * systemd-repart: read LUKS encryption key from $CREDENTIALS_PATH | |
1455 | ||
1456 | * systemd-repart: add a switch to factory reset the partition table without | |
1457 | immediately applying the new configuration again. i.e. --factory-reset=leave | |
1458 | or so. (this is useful to factory reset an image, then putting it into | |
1459 | another machine, ensuring that luks key is generated on new machine, not old) | |
1460 | ||
1461 | * systemd-repart: support setting up dm-integrity with HMAC | |
1462 | ||
1463 | * systemd-repart: maybe remove half-initialized image on failure. It fails | |
1464 | if the output file exists, so a repeated invocation will usually fail if | |
1465 | something goes wrong on the way. | |
1466 | ||
1467 | * systemd-repart: drop pager mode on normal operation? | |
1468 | ||
1469 | * systemd-repart: by default generate minimized partition tables (i.e. tables | |
1470 | that only cover the space actually used, excluding any free space at the | |
1471 | end), in order to maximize dd'ability. Requires libfdisk work, see | |
1472 | https://github.com/karelzak/util-linux/issues/907 | |
1473 | ||
1474 | * systemd-repart: MBR partition table support. Care needs to be taken regarding | |
1475 | Type=, so that partition definitions can sanely apply to both the GPT and the | |
1476 | MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types | |
1477 | for the two partition types explicitly. And provide an internal mapping so | |
1478 | that "Type=linux-generic" maps to the right types for both partition tables | |
1479 | automatically. | |
1480 | ||
1481 | * systemd-repart: allow sizing partitions as factor of available RAM, so that | |
1482 | we can reasonably size swap partitions for hibernation. | |
1483 | ||
1484 | * systemd-repart: allow boolean option that ensures that if existing partition | |
1485 | doesn't exist within the configured size bounds the whole command fails. This | |
1486 | is useful to implement ESP vs. XBOOTLDR schemes in installers: have one set | |
1487 | of repart files for the case where ESP is large enough and one where it isn't | |
1488 | and XBOOTLDR is added in instead. Then apply the former first, and if it | |
1489 | fails to apply use the latter. | |
1490 | ||
1491 | * systemd-repart: add per-partition option to never reuse existing partition | |
1492 | and always create anew even if matching partition already exists. | |
1493 | ||
1494 | * systemd-repart: add per-partition option to fail if partition already exist, | |
1495 | i.e. is not added new. Similar, add option to fail if partition does not exist yet. | |
1496 | ||
1497 | * systemd-repart: allow disabling growing of specific partitions, or making | |
1498 | them (think ESP: we don't ever want to grow it, since we cannot resize vfat) | |
1499 | ||
1500 | * systemd-repart: make it a static checker during early boot for existence and | |
1501 | absence of other partitions for trusted boot environments | |
1502 | ||
b44be3ec | 1503 | * document: |
8b8f2591 | 1504 | - document that deps in [Unit] sections ignore Alias= fields in |
b44be3ec LP |
1505 | [Install] units of other units, unless those units are disabled |
1506 | - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets | |
b44be3ec | 1507 | - document that service reload may be implemented as service reexec |
f38afcd0 LP |
1508 | - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr. |
1509 | - document systemd-journal-flush.service properly | |
f38afcd0 LP |
1510 | - documentation: recommend to connect the timer units of a service to the service via Also= in [Install] |
1511 | - man: document the very specific env the shutdown drop-in tools live in | |
5cf821ac ZJS |
1512 | - man: add more examples to man pages, |
1513 | - in particular an example how to do the equivalent of switching runlevels | |
f38afcd0 | 1514 | - man: maybe sort directives in man pages, and take sections from --help and apply them to man too |
17ec531f | 1515 | - document root=gpt-auto properly |
b44be3ec LP |
1516 | |
1517 | * systemctl: | |
b44be3ec LP |
1518 | - add systemctl switch to dump transaction without executing it |
1519 | - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done | |
1520 | - "systemctl disable" on a static unit prints no message and does | |
1521 | nothing. "systemctl enable" does nothing, and gives a bad message | |
1522 | about it. Should fix both to print nice actionable messages. | |
1523 | - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service | |
1524 | - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible | |
d28315e4 | 1525 | - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards? |
b44be3ec | 1526 | - systemctl: "Journal has been rotated since unit was started." message is misleading |
61233823 | 1527 | - systemctl status output should include list of triggering units and their status |
f38afcd0 | 1528 | |
07eabc2b LB |
1529 | * introduce an option (or replacement) for "systemctl show" that outputs all |
1530 | properties as JSON, similar to busctl's new JSON output. In contrast to that | |
1531 | it should skip the variant type string though. | |
8b04b925 | 1532 | |
07eabc2b LB |
1533 | * add an explicit "vertical" mode to format-table, so that "systemctl |
1534 | status"-like outputs (i.e. with a series of field names left and values | |
1535 | right) become genuine first class citizens, and we gain automatic, sane JSON | |
1536 | output for them. | |
d2e83c23 | 1537 | |
07eabc2b LB |
1538 | * Add a "systemctl list-units --by-slice" mode or so, which rearranges the |
1539 | output of "systemctl list-units" slightly by showing the tree structure of | |
1540 | the slices, and the units attached to them. | |
a19554ed | 1541 | |
07eabc2b LB |
1542 | * add "systemctl wait" or so, which does what "systemd-run --wait" does, but |
1543 | for all units. It should be both a way to pin units into memory as well as a | |
1544 | wait to retrieve their exit data. | |
a7a3f28b | 1545 | |
07eabc2b LB |
1546 | * show whether a service has out-of-date configuration in "systemctl status" by |
1547 | using mtime data of ConfigurationDirectory=. | |
08f95888 | 1548 | |
07eabc2b LB |
1549 | * "systemctl preset-all" should probably order the unit files it |
1550 | operates on lexicographically before starting to work, in order to | |
1551 | ensure deterministic behaviour if two unit files conflict (like DMs | |
1552 | do, for example) | |
dcfc4b2e | 1553 | |
07eabc2b LB |
1554 | * add "systemctl start -v foobar.service" that shows logs of a service |
1555 | while the start command runs. This is non-trivial to do without | |
1556 | races though, since we should flush out all journal messages before | |
1557 | returning from the "systemctl stop". | |
71ef24d0 | 1558 | |
07eabc2b LB |
1559 | * systemctl: if some operation fails, show log output? |
1560 | ||
1561 | * Add a new verb "systemctl top" | |
1562 | ||
1563 | * unit install: | |
1564 | - "systemctl mask" should find all names by which a unit is accessible | |
1565 | (i.e. by scanning for symlinks to it) and link them all to /dev/null | |
1b89884b | 1566 | |
b44be3ec | 1567 | * nspawn: |
e25b5a8d DH |
1568 | - emulate /dev/kmsg using CUSE and turn off the syslog syscall |
1569 | with seccomp. That should provide us with a useful log buffer that | |
1570 | systemd can log to during early boot, and disconnect container logs | |
1571 | from the kernel's logs. | |
1572 | - as soon as networkd has a bus interface, hook up --network-interface=, | |
1573 | --network-bridge= with networkd, to trigger netdev creation should an | |
1574 | interface be missing | |
e25b5a8d DH |
1575 | - a nice way to boot up without machine id set, so that it is set at boot |
1576 | automatically for supporting --ephemeral. Maybe hash the host machine id | |
1577 | together with the machine name to generate the machine id for the container | |
1578 | - fix logic always print a final newline on output. | |
1579 | https://github.com/systemd/systemd/pull/272#issuecomment-113153176 | |
1580 | - should optionally support receiving WATCHDOG=1 messages from its payload | |
1581 | PID 1... | |
e25b5a8d DH |
1582 | - optionally automatically add FORWARD rules to iptables whenever nspawn is |
1583 | running, remove them when shut down. | |
e25b5a8d | 1584 | |
07eabc2b LB |
1585 | * nspawn: add support for sysext extensions, too. i.e. a new --extension= |
1586 | switch that takes one or more arguments, and applies the extensions already | |
1587 | during startup. | |
1588 | ||
1589 | * when main nspawn supervisor process gets suspended due to SIGSTOP/SIGTTOU or | |
1590 | so, freeze the payload too. | |
1591 | ||
1592 | * machined: add API to acquire UID range. add API to mount/dissect loopback | |
1593 | file. Both protected by PK. Then make nspawn use these APIs to run | |
1594 | unprivileged containers. i.e. push the truly privileged bits into machined, | |
1595 | so that the client side can remain entirely unprivileged, with SUID or | |
1596 | anything like that. | |
1597 | ||
1598 | * nspawn: support time namespaces | |
1599 | ||
1600 | * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events, | |
1601 | so that we make cgroup agent logic safe | |
1602 | ||
1603 | * nspawn/machined: add API to invoke binary in container, then use that as | |
1604 | fallback in "machinectl shell" | |
1605 | ||
1606 | * nspawn: make nspawn suitable for shell pipelines: instead of triggering a | |
1607 | hangup when input is finished, send ^D, which synthesizes an EOF. Then wait | |
1608 | for hangup or ^D before passing on the EOF. | |
1609 | ||
1610 | * nspawn: greater control over selinux label? | |
1611 | ||
1612 | * nspawn: support that /proc, /sys/, /dev are pre-mounted | |
1613 | ||
e25b5a8d | 1614 | * machined: |
e25b5a8d DH |
1615 | - add an API so that libvirt-lxc can inform us about network interfaces being |
1616 | removed or added to an existing machine | |
1617 | - "machinectl migrate" or similar to copy a container from or to a | |
1618 | difference host, via ssh | |
e25b5a8d DH |
1619 | - introduce systemd-nspawn-ephemeral@.service, and hook it into |
1620 | "machinectl start" with a new --ephemeral switch | |
1621 | - "machinectl status" should also show internal logs of the container in | |
1622 | question | |
e25b5a8d DH |
1623 | - "machinectl history" |
1624 | - "machinectl diff" | |
1625 | - "machinectl commit" that takes a writable snapshot of a tree, invokes a | |
1626 | shell in it, and marks it read-only after use | |
1627 | ||
abd55b16 | 1628 | * udev: |
abd55b16 | 1629 | - move to LGPL |
abd55b16 KS |
1630 | - kill scsi_id |
1631 | - add trigger --subsystem-match=usb/usb_device device | |
e8d842a0 | 1632 | - reimport udev db after MOVE events for devices without dev_t |
b8217b7b | 1633 | |
e25b5a8d DH |
1634 | * coredump: |
1635 | - save coredump in Windows/Mozilla minidump format | |
73a99163 | 1636 | - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps |
87a8baa3 LP |
1637 | |
1638 | * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting) | |
1639 | ||
f38afcd0 | 1640 | * tmpfiles: |
f38afcd0 | 1641 | - apply "x" on "D" too (see patch from William Douglas) |
614cc34f | 1642 | - instead of ignoring unknown fields, reject them. |
e25b5a8d DH |
1643 | - creating new directories/subvolumes/fifos/device nodes |
1644 | should not follow symlinks. None of the other adjustment or creation | |
1645 | calls follow symlinks. | |
36f57e02 | 1646 | - add --test mode |
ba405b22 ZJS |
1647 | - teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4 |
1648 | project quota | |
1258097c | 1649 | |
af6f0d42 TG |
1650 | * udev-link-config: |
1651 | - Make sure ID_PATH is always exported and complete for | |
1652 | network devices where possible, so we can safely rely | |
1653 | on Path= matching | |
af6f0d42 | 1654 | |
88e4d1d7 | 1655 | * sd-rtnl: |
88e4d1d7 | 1656 | - add support for more attribute types |
c589a0e6 | 1657 | - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places |
88e4d1d7 | 1658 | |
0a4b9a07 | 1659 | * networkd: |
c74ecd71 TG |
1660 | - add more keys to [Route] and [Address] sections |
1661 | - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config) | |
e8d842a0 | 1662 | - add reduced [Link] support to .network files |
798e174a | 1663 | - properly handle routerless dhcp leases |
a8eaaee7 | 1664 | - work with non-Ethernet devices |
e25b5a8d | 1665 | - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from? |
e25b5a8d DH |
1666 | - the DHCP lease data (such as NTP/DNS) is still made available when |
1667 | a carrier is lost on a link. It should be removed instantly. | |
1668 | - expose in the API the following bits: | |
e2da6491 | 1669 | - option 15, domain name |
38b38500 | 1670 | - option 12, hostname and/or option 81, fqdn |
e25b5a8d DH |
1671 | - option 123, 144, geolocation |
1672 | - option 252, configure http proxy (PAC/wpad) | |
1673 | - provide a way to define a per-network interface default metric value | |
1674 | for all routes to it. possibly a second default for DHCP routes. | |
1675 | - allow Name= to be specified repeatedly in the [Match] section. Maybe also | |
1676 | support Name=foo*|bar*|baz ? | |
e25b5a8d | 1677 | - whenever uplink info changes, make DHCP server send out FORCERENEW |
155e8b9a | 1678 | |
07eabc2b LB |
1679 | * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us |
1680 | ||
d5e172d2 ZJS |
1681 | * Figure out how to do unittests of networkd's state serialization |
1682 | ||
ac976532 | 1683 | * dhcp: |
424a8732 | 1684 | - figure out how much we can increase Maximum Message Size |
ac976532 | 1685 | |
37d8b536 PF |
1686 | * dhcp6: |
1687 | - add functions to set previously stored IPv6 addresses on startup and get | |
1688 | them at shutdown; store them in client->ia_na | |
1689 | - write more test cases | |
37d8b536 | 1690 | - implement reconfigure support, see 5.3., 15.11. and 22.20. |
37d8b536 | 1691 | - implement support for temporary adressess (IA_TA) |
37d8b536 PF |
1692 | - implement dhcpv6 authentication |
1693 | - investigate the usefulness of Confirm messages; i.e. are there any | |
1694 | situations where the link changes without any loss in carrier detection | |
1695 | or interface down | |
1696 | - some servers don't do rapid commit without a filled in IA_NA, verify | |
1697 | this behavior | |
4a77c53d | 1698 | - RouteTable= ? |
