1 | Bugfixes: | |
2 | ||
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. | |
6 | ||
7 | External: | |
8 | ||
9 | * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros. | |
10 | ||
11 | * wiki: update journal format documentation for lz4 additions | |
12 | ||
13 | Janitorial Clean-ups: | |
14 | ||
15 | * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again | |
16 | ||
17 | * rework mount.c and swap.c to follow proper state enumeration/deserialization | |
18 | semantics, like we do for device.c now | |
19 | ||
20 | Features: | |
21 | ||
22 | * if /usr/bin/swapoff fails due to OOM, log a friendly explanatory message about it | |
23 | ||
24 | * build short web pages out of each catalog entry, build them along with man | |
25 | pages, and include hyperlinks to them in the journal output | |
26 | ||
27 | * machined: add API to acquire UID range. add API to mount/dissect loopback | |
28 | file. Both protected by PK. Then make nspawn use these APIs to run | |
29 | unprivileged containers. i.e. push the truly privileged bits into machined, | |
30 | so that the client side can remain entirely unprivileged, with SUID or | |
31 | anything like that. | |
32 | ||
33 | * add "throttling" to sd-event event sources: optionally, when we wake up too | |
34 | often for one, let's turn it off entirely for a while. Use that for the | |
35 | /proc/self/mountinfo logic. | |
36 | ||
37 | * move our systemd-user PAM snippet to /usr/, which PAM appears to support | |
38 | these days | |
39 | ||
40 | * nspawn: support time namespaces | |
41 | ||
42 | * add ConditionSecurity=tpm2 | |
43 | ||
44 | * pid1: Move to tracking of main pid/control pid of units per pidfd | |
45 | ||
46 | * pid1: support new clone3() fork-into-cgroup feature | |
47 | ||
48 | * pid1: also remove PID files of a service when the service starts, not just | |
49 | when it exits | |
50 | ||
51 | * systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum, | |
52 | mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such | |
53 | ||
54 | * make "systemd-dissect" an official supported tool, i.e. move to /usr/bin/ and | |
55 | provide man page. Given that we now have a tool that can generate images like | |
56 | this, it's useful to have one that can dump contents of them, too. | |
57 | ||
58 | * All tools that support --root= should also learn --image= so that they can | |
59 | operate on disk images directly. Specifically: bootctl, firstboot, tmpfiles, | |
60 | sysusers, systemctl, repart, journalctl, coredumpctl. | |
61 | ||
62 | * per-service credential system. Specifically: add LoadCredential= (for loading | |
63 | cred from file), AcquireCredential= (for asking user for cred, via | |
64 | ask-password), PassCredential= (for passing on credential systemd itself | |
65 | got). Then, place credentials in a per-service, immutable ramfs instance (so | |
66 | that it cannot be swapped out), destroy after use. Also pass via keyring | |
67 | (with graceful fallback to cover for containers). Define CredentialPath= for | |
68 | defining subdir of /run/credentials/ where to place it. Set $CREDENTIAL_PATH | |
69 | env var for services to the result. Also pass via fd passing (optionally). | |
70 | ||
71 | * homed: add native recovery key support. use 48 lowercase modhex characters | |
72 | (192bit), show qr code of it, include pattern expression in user record. | |
73 | ||
74 | * homed: introduce "degraded" state for home directories that weren't cleanly | |
75 | unmounted (use xattr we add and remove on the loop back file) | |
76 | ||
77 | * homed: during login resize fs automatically towards size goal. Specifically, | |
78 | resize to diskSize if possible, but leave a certain amount (configured by a | |
79 | new value diskLeaveFreeSize) of space free on the backing fs. | |
80 | ||
81 | * homed: permit multiple user record signing keys to be used locally, and pick | |
82 | the right one for signing records automatically depending on a pre-existing | |
83 | signature | |
84 | ||
85 | * homed: add a way to "adopt" a home directory, i.e. strip foreign signatures | |
86 | and insert a local signature instead. | |
87 | ||
88 | * homed: as an extension to the directory+subvolume backend: if located on | |
89 | especially marked fs, then sync down password into LUKS header of that fs, | |
90 | and always verify passwords against it too. Bootstrapping is a problem | |
91 | though: if no one is logged in (or no other user even exists yet), how do you | |
92 | unlock the volume in order to create the first user and add the first pw. | |
93 | ||
94 | * homed: support new FS_IOC_ADD_ENCRYPTION_KEY ioctl for setting up fscrypt | |
95 | ||
96 | * busctl: maybe expose a verb "ping" for pinging a dbus service to see if it | |
97 | exists and responds. | |
98 | ||
99 | * homed: maybe pre-create ~/.cache as subvol so that it can have separate quota | |
100 | easily? | |
101 | ||
102 | * when systemd-nspawn and suchlike dissect an OS image, and there are multiple | |
103 | root partitions, do an strverscmp() on the partition label and boot | |
104 | first. That is inspired how sd-boot figures out which kernel to boot, and | |
105 | thus allows defining OS images which can be A/B updated and we default to the | |
106 | newest version automatically, both in nspawn and in sd-boot | |
107 | ||
108 | * cryptsetup/homed: also support FIDO2 HMAC password logic for unlocking | |
109 | devices. (see: https://github.com/mjec/fido2-hmac-secret) | |
110 | ||
111 | * systemd-gpt-auto should probably set x-systemd.growfs on the mounts it | |
112 | creates | |
113 | ||
114 | * homed/userdb: distinguish passwords and recovery keys in the records, since | |
115 | we probably want to use different PBKDF algorithms/settings for them: | |
116 | passwords have low entropy but recovery keys should have good entropy key | |
117 | hence we can make them quicker to work. | |
118 | ||
119 | * bootctl: | |
120 | - teach it to prepare an ESP wholesale, i.e. with mkfs.vfat invocation | |
121 | - teach it to copy in unified kernel images and maybe type #1 boot loader spec entries from host | |
122 | - make it operate on loopback files, dissecting enough to find ESP to operate on | |
123 | ||
124 | * by default, in systemd --user service bump the OOMAdjust to 100, as privs | |
125 | allow so that systemd survives | |
126 | ||
127 | * cryptsetup: allow encoding key directly in /etc/crypttab, maybe with a | |
128 | "base64:" prefix. Useful in particular for pkcs11 mode. | |
129 | ||
130 | * cryptsetup: reimplement the mkswap/mke2fs in cryptsetup-generator to use | |
131 | systemd-makefs.service instead. | |
132 | ||
133 | * socket units: allow creating a udev monitor socket with ListenDevices= or so, | |
134 | with matches, then activate app through that passing socket over | |
135 | ||
136 | * unify on openssl: | |
137 | - port sd_id128_get_machine_app_specific() over from khash | |
138 | - port resolved over from libgcrypt (DNSSEC code) | |
139 | - port journald + fsprg over from libgcrypt | |
140 | - port importd over from libgcrypt | |
141 | - when that's done: kill khash.c | |
142 | - when that's done: kill gnutls support in resolved | |
143 | ||
144 | * kill zenata, all hail weblate? | |
145 | ||
146 | * when we resize disks (homed?) always round up to 4K sectors, not 512K | |
147 | ||
148 | * add growvol and makevol options for /etc/crypttab, similar to | |
149 | x-systemd.growfs and x-systemd-makefs. | |
150 | ||
151 | * hook up the TPM to /etc/crypttab, with a new option that is similar to the | |
152 | new PKCS#11 option in crypttab, and allows unlocking a LUKS volume via a key | |
153 | unsealed from the TPM. Optionally, if TPM is not available fall back to | |
154 | TPM-less mode, and set up linear DM mapping instead (inspired by kpartx), so | |
155 | that the device paths stay the same, regardless if crypto is used or not. | |
156 | ||
157 | * systemd-repart: by default generate minimized partition tables (i.e. tables | |
158 | that only cover the space actually used, excluding any free space at the | |
159 | end), in order to maximize dd'ability. Requires libfdisk work, see | |
160 | https://github.com/karelzak/util-linux/issues/907 | |
161 | ||
162 | * systemd-repart: optionally, allow specifying a path to initialize new | |
163 | partitions from, i.e. an fs image file or a source device node. This would | |
164 | then turn systemd-repart into a simple installer: with a few .repart files | |
165 | you could replicate the host system on another device. a full installer would | |
166 | then be: "systemd-repart /dev/sda && bootctl install /dev/sda && | |
167 | systemd-firstboot --image= …" | |
168 | ||
169 | * systemd-repart: MBR partition table support. Care needs to be taken regarding | |
170 | Type=, so that partition definitions can sanely apply to both the GPT and the | |
171 | MBR case. Idea: accept syntax "Type=gpt:home mbr:0x83" for setting the types | |
172 | for the two partition types explicitly. And provide an internal mapping so | |
173 | that "Type=linux-generic" maps to the right types for both partition tables | |
174 | automatically. | |
175 | ||
176 | * systemd-repart: allow sizing partitions as factor of available RAM, so that | |
177 | we can reasonably size swap partitions for hibernation. | |
178 | ||
179 | * systemd-repart: allow running mkfs before making partitions pop up + | |
180 | encryption via LUKS to allow booting into an empty root with only /usr mounted in | |
181 | ||
182 | * systemd-repart: allow managing the gpt read-only partition flag + auto-mount flag | |
183 | ||
184 | * systemd-repart: allow disabling growing of specific partitions, or making | |
185 | them (think ESP: we don't ever want to grow it, since we cannot resize vfat) | |
186 | ||
187 | * systemd-repart: add specifier expansion, add especifier that refers to root | |
188 | device node of current system, /usr device node, and matching verity, so that | |
189 | an installer can be made a "copy" installer of the booted OS | |
190 | ||
191 | * systemd-repart: make it a static checker during early boot for existence and | |
192 | absence of other partitions for trusted boot environments | |
193 | ||
194 | * systemd-repart: allow config of partition uuid | |
195 | ||
196 | * userdb: allow username prefix searches in varlink API, allow realname and | |
197 | realname substr searches in varlink API | |
198 | ||
199 | * userdb: allow uid/gid range checks | |
200 | ||
201 | * userdb: allow existence checks | |
202 | ||
203 | * pid1: activation by journal search expression | |
204 | ||
205 | * when switching root from initrd to host, set the machine_id env var so that | |
206 | if the host has no machine ID set yet we continue to use the random one the | |
207 | initrd had set. | |
208 | ||
209 | * sd-event: add native support for P_ALL waitid() watching, then move PID 1 to | |
210 | it fo reaping assigned but unknown children. This needs to some special care | |
211 | to operate somewhat sensibly in light of priorities: P_ALL will return | |
212 | arbitrary processes, regardless of the priority we want to watch them with, | |
213 | hence on each event loop iteration check all processes which we shall watch | |
214 | with higher prio explicitly, and then watch the entire rest with P_ALL. | |
215 | ||
216 | * tweak sd-event's child watching: keep a prioq of children to watch and use | |
217 | waitid() only on the children with the highest priority until one is waitable | |
218 | and ignore all lower-prio ones from that point on | |
219 | ||
220 | * maybe introduce xattrs that can be set on the root dir of the root fs | |
221 | partition that declare the volatility mode to use the image in. Previously I | |
222 | thought marking this via GPT partition flags but that's not ideal since | |
223 | that's outside of the LUKS encryption/verity verification, and we probably | |
224 | shouldn't operate in a volatile mode unless we got told so from a trusted | |
225 | source. | |
226 | ||
227 | * figure out automatic partition discovery when combining writable root dir | |
228 | with immutable /usr | |
229 | ||
230 | * coredump: maybe when coredumping read a new xattr from /proc/$PID/exe that | |
231 | may be used to mark a whole binary as non-coredumpable. Would fix: | |
232 | https://bugs.freedesktop.org/show_bug.cgi?id=69447 | |
233 | ||
234 | * teach parse_timestamp() timezones like the calendar spec already knows it | |
235 | ||
236 | * beef up hibernation to optionally do swapon/swapoff immediately before/after | |
237 | the hibernation | |
238 | ||
239 | * beef up s2h to implement a battery watch loop: instead of entering | |
240 | hibernation unconditionally after coming back from resume make a decision | |
241 | based on the battery load level: if battery level is above a specific | |
242 | threshold, go to suspend again, only hibernate if below it. This means we'd | |
243 | stick to suspend usually, but fall back to hibernation only when battery runs | |
244 | empty (well, subject to our sampling interval). Related to this, check if we | |
245 | can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too, | |
246 | i.e. see if it can wake up machines from suspend, so that we could resume | |
247 | automatically when the system is low on power and move automatically to | |
248 | hibernation mode. (see | |
249 | https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf | |
250 | section 10.2.2.8 and | |
251 | https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources | |
252 | at the end). | |
253 | ||
254 | * add an explicit "vertical" mode to format-table, so that "systemctl | |
255 | status"-like outputs (i.e. with a series of field names left and values | |
256 | right) become genuine first class citizens, and we gain automatic, sane JSON | |
257 | output for them. | |
258 | ||
259 | * systemd-firstboot: teach it dissector magic, so that you can point it to some | |
260 | disk image and it will just set everything in it all behind the scenes. | |
261 | ||
262 | * We should probably replace /var/log/README, /etc/rc.d/README with symlinks | |
263 | that are linked to these places instead of copied. After all they are | |
264 | constant vendor data. | |
265 | ||
266 | * maybe add kernel cmdline params: to force random seed crediting | |
267 | ||
268 | * nspawn: on cgroupsv1 issue cgroup empty handler process based on host events, | |
269 | so that we make cgroup agent logic safe | |
270 | ||
271 | * nspawn/machined: add API to invoke binary in container, then use that as | |
272 | fallback in "machinectl shell" | |
273 | ||
274 | * logind: rework pam_logind to also do a bus call in case of invocation from | |
275 | user@.service, which returns the XDG_RUNTIME_DIR value, and make this | |
276 | behaviour selectable via pam module option. | |
277 | ||
278 | * homed: | |
279 | - when user tries to log into record signed by unrecognized key, automatically add key to our chain after polkit auth | |
280 | - hook up machined/nspawn users with a varlink user query interface | |
281 | - rollback when resize fails mid-operation | |
282 | - GNOME's side for forget key on suspend (requires rework so that lock screen runs outside of uid) | |
283 | - resize on login? | |
284 | - shrink fs on logout? | |
285 | - update LUKS password on login if we find there's a password that unlocks the JSON record but not the LUKS device. | |
286 | - create on activate? | |
287 | - properties: icon url?, preferred session type?, administrator bool (which translates to 'wheel' membership)?, address?, telephone?, vcard?, samba stuff?, parental controls? | |
288 | - communicate clearly when usb stick is safe to remove. probably involves | |
289 | beefing up logind to make pam session close hook synchronous and wait until | |
290 | systemd --user is shut down. | |
291 | - logind: maybe keep a "busy fd" as long as there's a non-released session around or the user@.service | |
292 | - maybe make automatic, read-only, time-based reflink-copies of LUKS disk images (think: time machine) | |
293 | - distinguish destroy / remove (i.e. currently we can unregister a user, unregister+remove their home directory, but not just remove their home directory) | |
294 | - in systemd's PAMName= logic: query passwords with ssh-askpassword, so that we can make "loginctl set-linger" mode work | |
295 | - fingerprint authentication, pattern authentication, … | |
296 | - make sure "classic" user records can also be managed by homed | |
297 | - description field for groups | |
298 | - make size of $XDG_RUNTIME_DIR configurable in user record | |
299 | - reuse pwquality magic in firstboot | |
300 | - query password from kernel keyring first | |
301 | - update even if record is "absent" | |
302 | - add a "access mode" + "fstype" field to the "status" section of json identity records reflecting the actually used access mode and fstype, even on non-luks backends | |
303 | - move acct mgmt stuff from pam_systemd_home to pam_systemd? | |
304 | - when "homectl --pkcs11-token-uri=" is used, synthesize ssh-authorized-keys records for all keys we have private keys on the stick for | |
305 | - make slice for users configurable (requires logind rework) | |
306 | - logind: populate auto-login list bus property from PKCS#11 token | |
307 | - when determining state of a LUKS home directory, check DM suspended sysfs file | |
308 | ||
309 | * introduce a new per-process uuid, similar to the boot id, the machine id, the | |
310 | invocation id, that is derived from process creds, specifically a hashed | |
311 | combination of AT_RANDOM + getpid() + the starttime from | |
312 | /proc/self/status. Then add these ids implicitly when logging. Deriving this | |
313 | uuid from these three things has the benefit that it can be derived easily | |
314 | from /proc/$PID/ in a stable, and unique way that changes on both fork() and | |
315 | exec(). | |
316 | ||
317 | * let's not GC a unit while its ratelimits are still pending | |
318 | ||
319 | * when killing due to service watchdog timeout maybe detect whether target | |
320 | process is under ptracing and then log loudly and continue instead. | |
321 | ||
322 | * introduce a new group to own TPM devices | |
323 | ||
324 | * make rfkill uaccess controllable by default, i.e. steal rule from | |
325 | gnome-bluetooth and friends | |
326 | ||
327 | * tweak journald context caching. In addition to caching per-process attributes | |
328 | keyed by PID, cache per-cgroup attributes (i.e. the various xattrs we read) | |
329 | keyed by cgroup path, and guarded by ctime changes. This should provide us | |
330 | with a nice speed-up on services that have many processes running in the same | |
331 | cgroup. | |
332 | ||
333 | * make MAINPID= message reception checks even stricter: if service uses User=, | |
334 | then check sending UID and ignore message if it doesn't match the user or | |
335 | root. | |
336 | ||
337 | * maybe trigger a uevent "change" on a device if "systemctl reload xyz.device" | |
338 | is issued. | |
339 | ||
340 | * when importing an fs tree with machined, optionally apply userns-rec-chown | |
341 | ||
342 | * when importing an fs tree with machined, complain if image is not an OS | |
343 | ||
344 | * Maybe introduce a helper safe_exec() or so, which is to execve() which | |
345 | safe_fork() is to fork(). And then make revert the RLIMIT_NOFILE soft limit | |
346 | to 1K implicitly, unless explicitly opted-out. | |
347 | ||
348 | * rework seccomp/nnp logic that even if User= is used in combination with | |
349 | a seccomp option we don't have to set NNP. For that, change uid first whil | |
350 | keeping CAP_SYS_ADMIN, then apply seccomp, the drop cap. | |
351 | ||
352 | * add a concept for automatically loading per-unit secrets off disk and | |
353 | inserting them into the kernel keyring. Maybe SecretsDirectory= similar to | |
354 | ConfigurationDirectory=. | |
355 | ||
356 | * when no locale is configured, default to UEFI's PlatformLang variable | |
357 | ||
358 | * bootctl,sd-boot: actually honour the "architecture" key | |
359 | ||
360 | * add a new syscall group "@esoteric" for more esoteric stuff such as bpf() and | |
361 | usefaultd() and make systemd-analyze check for it. | |
362 | ||
363 | * paranoia: whenever we process passwords, call mlock() on the memory | |
364 | first. i.e. look for all places we use free_and_erasep() and | |
365 | augment them with mlock(). Also use MADV_DONTDUMP. | |
366 | ||
367 | * Move RestrictAddressFamily= to the new cgroup create socket | |
368 | ||
369 | * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly | |
370 | patching around | |
371 | ||
372 | * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in | |
373 | log.c and sd-journal-send | |
374 | ||
375 | * optionally: turn on cgroup delegation for per-session scope units | |
376 | ||
377 | * introduce per-unit (i.e. per-slice, per-service) journal log size limits. | |
378 | ||
379 | * sd-boot: automatically load EFI modules from some drop-in dir, so that people | |
380 | can add in file system drivers and such | |
381 | ||
382 | * sd-boot: optionally, show boot menu when previous default boot item has | |
383 | non-zero "tries done" count | |
384 | ||
385 | * introduce an option (or replacement) for "systemctl show" that outputs all | |
386 | properties as JSON, similar to busctl's new JSON output. In contrast to that | |
387 | it should skip the variant type string though. | |
388 | ||
389 | * augment CODE_FILE=, CODE_LINE= with something like CODE_BASE= or so which | |
390 | contains some identifier for the project, which allows us to include | |
391 | clickable links to source files generating these log messages. The identifier | |
392 | could be some abberviated URL prefix or so (taking inspiration from Go | |
393 | imports). For example, for systemd we could use | |
394 | CODE_BASE=github.com/systemd/systemd/blob/98b0b1123cc or so which is | |
395 | sufficient to build a link by prefixing "http://" and suffixing the | |
396 | CODE_FILE. | |
397 | ||
398 | * Augment MESSAGE_ID with MESSAGE_BASE, in a similar fashion so that we can | |
399 | make clickable links from log messages carrying a MESSAGE_ID, that lead to | |
400 | some explanatory text online. | |
401 | ||
402 | * maybe extend .path units to expose fanotify() per-mount change events | |
403 | ||
404 | * Add a "systemctl list-units --by-slice" mode or so, which rearranges the | |
405 | output of "systemctl list-units" slightly by showing the tree structure of | |
406 | the slices, and the units attached to them. | |
407 | ||
408 | * the a-posteriori stopping of units bound to units that disappeared logic | |
409 | should be reworked: there should be a queue of units, and we should only | |
410 | enqueue stop jobs from a defer event that processes queue instead of | |
411 | right-away when we find a unit that is bound to one that doesn't exist | |
412 | anymore. (similar to how the stop-unneeded queue has been reworked the same | |
413 | way) | |
414 | ||
415 | * nspawn: make nspawn suitable for shell pipelines: instead of triggering a | |
416 | hangup when input is finished, send ^D, which synthesizes an EOF. Then wait | |
417 | for hangup or ^D before passing on the EOF. | |
418 | ||
419 | * When reloading configuration PID 1 should reset all its properties to the | |
420 | original defaults before calling parse_config() | |
421 | ||
422 | * nspawn: greater control over selinux label? | |
423 | ||
424 | * hibernate/s2h: make this robust and safe to enable in Fedora by default. | |
425 | Specifically: | |
426 | ||
427 | 1. add resume_offset support to the resume code (i.e. support swap files | |
428 | properly) | |
429 | 2. check if swap is on weird storage and refuse if so | |
430 | 3. add auto-detection of hibernation images | |
431 | ||
432 | * cgroups: use inotify to get notified when somebody else modifies cgroups | |
433 | owned by us, then log a friendly warning. | |
434 | ||
435 | * beef up log.c with support for stripping ANSI sequences from strings, so that | |
436 | it is OK to include them in log strings. This would be particularly useful so | |
437 | that our log messages could contain clickable links for example for unit | |
438 | files and suchlike we operate on. | |
439 | ||
440 | * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration) | |
441 | ||
442 | * add attach --enable and attach --now (for attach+enable+start) | |
443 | ||
444 | * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the | |
445 | selected user is resolvable in the service even if it ships its own /etc/passwd) | |
446 | ||
447 | * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the | |
448 | other doesn't. What a disaster. Probably to exclude it. Also | |
449 | DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative | |
450 | numbers. | |
451 | ||
452 | * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as | |
453 | usually IN_ATTRIB is the right way to watch deleted files, as the former only | |
454 | fires when a file is actually removed from disk, i.e. the link count drops to | |
455 | zero and is not open anymore, while the latter happens when a file is | |
456 | unlinked from any dir. | |
457 | ||
458 | * port systemctl, busctl, … over to format-table.[ch]'s table formatters | |
459 | ||
460 | * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up | |
461 | ||
462 | * add --vacuum-xyz options to coredumpctl, matching those journalctl already has. | |
463 | ||
464 | * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all | |
465 | files and directories that are left writable for a unit, and which are | |
466 | removed after the unit goes down again. A bit like --ephemeral for | |
467 | systemd-nspawn but for system services. If used together with RootImage= this | |
468 | should reflink the image file itself. | |
469 | ||
470 | Related: add Ephemeral=<path1> <path2> … which would allow marking | |
471 | specific paths only like this. | |
472 | ||
473 | * add CopyFile= or so as unit file setting that may be used to copy files or | |
474 | directory trees from the host to the services RootImage= and RootDirectory= | |
475 | environment. Which we can use for /etc/machine-id and in particular | |
476 | /etc/resolv.conf. Should be smart and do something useful on read-only | |
477 | images, for example fallback to read-only bind mounting the file instead. | |
478 | ||
479 | * show invocation ID in systemd-run output | |
480 | ||
481 | * bypass SIGTERM state in unit files if KillSignal is SIGKILL | |
482 | ||
483 | * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1 | |
484 | and so on, which would mean we could report errors and such. | |
485 | ||
486 | * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4 | |
487 | project quota | |
488 | ||
489 | * introduce DefaultSlice= or so in system.conf that allows changing where we | |
490 | place our units by default, i.e. change system.slice to something | |
491 | else. Similar, ManagerSlice= should exist so that PID1's own scope unit could | |
492 | be moved somewhere else too. Finally machined and logind should get similar | |
493 | options so that it is possible to move user session scopes and machines to a | |
494 | different slice too by default. Usecase: people who want to put resources on | |
495 | the entire system, with the exception of one specific service. See: | |
496 | https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html | |
497 | ||
498 | * maybe rework get_user_creds() to query the user database if $SHELL is used | |
499 | for root, but only then. | |
500 | ||
501 | * be stricter with fds we receive for the fdstore: close them asynchronously | |
502 | ||
503 | * calenderspec: add support for week numbers and day numbers within a | |
504 | year. This would allow us to define "bi-weekly" triggers safely. | |
505 | ||
506 | * sd-bus: add vtable flag, that may be used to request client creds implicitly | |
507 | and asynchronously before dispatching the operation | |
508 | ||
509 | * make use of ethtool veth peer info in machined, for automatically finding out | |
510 | host-side interface pointing to the container. | |
511 | ||
512 | * add some special mode to LogsDirectory=/StateDirectory=… that allows | |
513 | declaring these directories without necessarily pulling in deps for them, or | |
514 | creating them when starting up. That way, we could declare that | |
515 | systemd-journald writes to /var/log/journal, which could be useful when we | |
516 | doing disk usage calculations and so on. | |
517 | ||
518 | * taint systemd if there are fewer than 65536 users assigned (userns) to the system. | |
519 | ||
520 | * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char | |
521 | ||
522 | * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for | |
523 | the runtime dir as we maintain for the fdstore: i.e. keep it around as long | |
524 | as the unit is running or has a job queued. | |
525 | ||
526 | * support projid-based quota in machinectl for containers | |
527 | ||
528 | * add a way to lock down cgroup migration: a boolean, which when set for a unit | |
529 | makes sure the processes in it can never migrate out of it | |
530 | ||
531 | * blog about fd store and restartable services | |
532 | ||
533 | * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document | |
534 | ||
535 | * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its | |
536 | magic meaning and is no longer upgraded to something else if set explicitly. | |
537 | ||
538 | * in the long run: permit a system with /etc/machine-id linked to /dev/null, to | |
539 | make it lose its identity, i.e. be anonymous. For this we'd have to patch | |
540 | through the whole tree to make all code deal with the case where no machine | |
541 | ID is available. | |
542 | ||
543 | * optionally, collect cgroup resource data, and store it in per-unit RRD files, | |
544 | suitable for processing with rrdtool. Add bus API to access this data, and | |
545 | possibly implement a CPULoad property based on it. | |
546 | ||
547 | * beef up pam_systemd to take unit file settings such as cgroups properties as | |
548 | parameters | |
549 | ||
550 | * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage | |
551 | the quota of a the user indicated in User= via unit file settings, like the | |
552 | other resource management concepts. Would mix nicely with DynamicUser=1. Or | |
553 | alternatively, do this with projids, so that we can also cover services | |
554 | running as root. Quota should probably cover all the special dirs such as | |
555 | StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it | |
556 | is set, plus the whole disk space any image configured with RootImage=. | |
557 | ||
558 | * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant | |
559 | disks to see if the UID is already in use. | |
560 | ||
561 | * add "systemctl wait" or so, which does what "systemd-run --wait" does, but | |
562 | for all units. It should be both a way to pin units into memory as well as a | |
563 | wait to retrieve their exit data. | |
564 | ||
565 | * expose IO accounting data on the bus, show it in systemd-run --wait and log | |
566 | about it in the resource log message | |
567 | ||
568 | * show whether a service has out-of-date configuration in "systemctl status" by | |
569 | using mtime data of ConfigurationDirectory=. | |
570 | ||
571 | * Add AddUser= setting to unit files, similar to DynamicUser=1 which however | |
572 | creates a static, persistent user rather than a dynamic, transient user. We | |
573 | can leverage code from sysusers.d for this. | |
574 | ||
575 | * add some optional flag to ReadWritePaths= and friends, that has the effect | |
576 | that we create the dir in question when the service is started. Example: | |
577 | ||
578 | ReadWritePaths=:/var/lib/foobar | |
579 | ||
580 | * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for | |
581 | the sd-journal logging socket, and, if the timeout is set to 0, sets | |
582 | O_NONBLOCK on it. That way people can control if and when to block for | |
583 | logging. | |
584 | ||
585 | * hostnamed: populate form factor data from a new hwdb database, so that old | |
586 | yogas can be recognized as "convertible" too, even if they predate the DMI | |
587 | "convertible" form factor | |
588 | ||
589 | * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing | |
590 | after all. Be strict however, only support the equivalent of nspawn's | |
591 | --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such | |
592 | as MAINPID. | |
593 | ||
594 | * Add ExecMonitor= setting. May be used multiple times. Forks off a process in | |
595 | the service cgroup, which is supposed to monitor the service, and when it | |
596 | exits the service is considered failed by its monitor. | |
597 | ||
598 | * track the per-service PAM process properly (i.e. as an additional control | |
599 | process), so that it may be queried on the bus and everything. | |
600 | ||
601 | * add a new "debug" job mode, that is propagated to unit_start() and for | |
602 | services results in two things: we raise SIGSTOP right before invoking | |
603 | execve() and turn off watchdog support. Then, use that to implement | |
604 | "systemd-gdb" for attaching to the start-up of any system service in its | |
605 | natural habitat. | |
606 | ||
607 | * gpt-auto logic: related to the above, maybe support a "secondary" root | |
608 | partition, that is mounted to / and is writable, and where the actual root's | |
609 | /usr is mounted into. | |
610 | ||
611 | * 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 | |
612 | ||
613 | * drop nss-myhostname in favour of nss-resolve? | |
614 | ||
615 | * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and | |
616 | then use that for the setting used in user@.service. It should be understood | |
617 | relative to the configured default value. | |
618 | ||
619 | * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us | |
620 | ||
621 | * enable LockMLOCK to take a percentage value relative to physical memory | |
622 | ||
623 | * Permit masking specific netlink APIs with RestrictAddressFamily= | |
624 | ||
625 | * nspawn: support that /proc, /sys/, /dev are pre-mounted | |
626 | ||
627 | * define gpt header bits to select volatility mode | |
628 | ||
629 | * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc | |
630 | ||
631 | * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away) | |
632 | ||
633 | * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave) | |
634 | ||
635 | * ProtectKeyRing= to take keyring calls away | |
636 | ||
637 | * RemoveKeyRing= to remove all keyring entries of the specified user | |
638 | ||
639 | * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill | |
640 | on PID 1 with the relevant signals, and makes relevant files in /sys and | |
641 | /proc (such as the sysrq stuff) unavailable | |
642 | ||
643 | * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things | |
644 | ||
645 | * journalctl: make sure -f ends when the container indicated by -M terminates | |
646 | ||
647 | * mount: automatically search for "main" partition of an image has multiple | |
648 | partitions | |
649 | ||
650 | * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set, | |
651 | find a way to map the User=/Group= of the service to the right name. This way | |
652 | a user/group for a service only has to exist on the host for the right | |
653 | mapping to work. | |
654 | ||
655 | * add bus API for creating unit files in /etc, reusing the code for transient units | |
656 | ||
657 | * add bus API to remove unit files from /etc | |
658 | ||
659 | * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only) | |
660 | ||
661 | * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the | |
662 | kernel doesn't support linkat() that replaces existing files, currently) | |
663 | ||
664 | * transient units: don't bother with actually setting unit properties, we | |
665 | reload the unit file anyway | |
666 | ||
667 | * journald: sigbus API via a signal-handler safe function that people may call | |
668 | from the SIGBUS handler | |
669 | ||
670 | * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown | |
671 | ||
672 | * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it | |
673 | in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle | |
674 | ||
675 | * cache sd_event_now() result from before the first iteration... | |
676 | ||
677 | * PID1: find a way how we can reload unit file configuration for | |
678 | specific units only, without reloading the whole of systemd | |
679 | ||
680 | * add an explicit parser for LimitRTPRIO= that verifies | |
681 | the specified range and generates sane error messages for incorrect | |
682 | specifications. | |
683 | ||
684 | * when we detect that there are waiting jobs but no running jobs, do something | |
685 | ||
686 | * push CPUAffinity= also into the "cpuset" cgroup controller | |
687 | ||
688 | * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn) | |
689 | ||
690 | * there's probably something wrong with having user mounts below /sys, | |
691 | as we have for debugfs. for example, src/core/mount.c handles mounts | |
692 | prefixed with /sys generally special. | |
693 | http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html | |
694 | ||
695 | * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline | |
696 | ||
697 | * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date | |
698 | ||
699 | * add a job mode that will fail if a transaction would mean stopping | |
700 | running units. Use this in timedated to manage the NTP service | |
701 | state. | |
702 | http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html | |
703 | ||
704 | * The udev blkid built-in should expose a property that reflects | |
705 | whether media was sensed in USB CF/SD card readers. This should then | |
706 | be used to control SYSTEMD_READY=1/0 so that USB card readers aren't | |
707 | picked up by systemd unless they contain a medium. This would mirror | |
708 | the behaviour we already have for CD drives. | |
709 | ||
710 | * networkd/udev: implement SR_IOV configuration in .link files: | |
711 | http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html | |
712 | ||
713 | * hostnamectl: show root image uuid | |
714 | ||
715 | * Find a solution for SMACK capabilities stuff: | |
716 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html | |
717 | ||
718 | * "systemctl preset-all" should probably order the unit files it | |
719 | operates on lexicographically before starting to work, in order to | |
720 | ensure deterministic behaviour if two unit files conflict (like DMs | |
721 | do, for example) | |
722 | ||
723 | * synchronize console access with BSD locks: | |
724 | http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html | |
725 | ||
726 | * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads: | |
727 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html | |
728 | ||
729 | * figure out when we can use the coarse timers | |
730 | ||
731 | * add "systemctl start -v foobar.service" that shows logs of a service | |
732 | while the start command runs. This is non-trivial to do without | |
733 | races though, since we should flush out all journal messages before | |
734 | returning from the "systemctl stop". | |
735 | ||
736 | * 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 | |
737 | ||
738 | * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment= | |
739 | ||
740 | * maybe allow timer units with an empty Units= setting, so that they | |
741 | can be used for resuming the system but nothing else. | |
742 | ||
743 | * what to do about udev db binary stability for apps? (raw access is not an option) | |
744 | ||
745 | * systemctl: if some operation fails, show log output? | |
746 | ||
747 | * systemctl edit: use equivalent of cat() to insert existing config as a comment, prepended with #. | |
748 | Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc. | |
749 | ||
750 | * exponential backoff in timesyncd when we cannot reach a server | |
751 | ||
752 | * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM | |
753 | ||
754 | * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share.... | |
755 | ||
756 | * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL | |
757 | (throughout the codebase, not only PID1) | |
758 | ||
759 | * resolved: | |
760 | - mDNS/DNS-SD | |
761 | - service registration | |
762 | - service/domain/types browsing | |
763 | - avahi compat | |
764 | - DNS-SD service registration from socket units | |
765 | - resolved should optionally register additional per-interface LLMNR | |
766 | names, so that for the container case we can establish the same name | |
767 | (maybe "host") for referencing the server, everywhere. | |
768 | - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?) | |
769 | - hook up resolved with machined-based address resolution | |
770 | ||
771 | * refcounting in sd-resolve is borked | |
772 | ||
773 | * Add a new verb "systemctl top" | |
774 | ||
775 | * add new gpt type for btrfs volumes | |
776 | ||
777 | * support empty /etc boots nicely: | |
778 | - nspawn/gpt-generator: introduce new gpt partition type for /usr | |
779 | ||
780 | * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them. | |
781 | ||
782 | * a way for container managers to turn off getty starting via $container_headless= or so... | |
783 | ||
784 | * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit | |
785 | ||
786 | * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services | |
787 | they run added to the initial transaction and thus confuse Type=idle. | |
788 | ||
789 | * add bus api to query unit file's X fields. | |
790 | ||
791 | * gpt-auto-generator: | |
792 | - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap? | |
793 | - Make /home automount rather than mount? | |
794 | ||
795 | * add generator that pulls in systemd-network from containers when | |
796 | CAP_NET_ADMIN is set, more than the loopback device is defined, even | |
797 | when it is otherwise off | |
798 | ||
799 | * MessageQueueMessageSize= (and suchlike) should use parse_iec_size(). | |
800 | ||
801 | * implement Distribute= in socket units to allow running multiple | |
802 | service instances processing the listening socket, and open this up | |
803 | for ReusePort= | |
804 | ||
805 | * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze | |
806 | $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls | |
807 | should SIGSTOP all unit processes in a loop until all processes of | |
808 | it are fully stopped. This can later be used for app management by | |
809 | desktop UIs such as gnome-shell to freeze apps that are not visible | |
810 | on screen, not unlike how job control works on the shell | |
811 | ||
812 | * cgroups: | |
813 | - implement per-slice CPUFairScheduling=1 switch | |
814 | - introduce high-level settings for RT budget, swappiness | |
815 | - how to reset dynamically changed unit cgroup attributes sanely? | |
816 | - when reloading configuration, apply new cgroup configuration | |
817 | - when recursively showing the cgroup hierarchy, optionally also show | |
818 | the hierarchies of child processes | |
819 | ||
820 | * transient units: | |
821 | - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt | |
822 | ||
823 | * when we detect low battery and no AC on boot, show pretty splash and refuse boot | |
824 | ||
825 | * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops | |
826 | ||
827 | * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1 | |
828 | ||
829 | * 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 | |
830 | ||
831 | * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs | |
832 | ||
833 | * If we try to find a unit via a dangling symlink, generate a clean | |
834 | error. Currently, we just ignore it and read the unit from the search | |
835 | path anyway. | |
836 | ||
837 | * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up | |
838 | ||
839 | * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted. | |
840 | ||
841 | * load .d/*.conf dropins for device units | |
842 | ||
843 | * sd-bus: | |
844 | - EBADSLT handling | |
845 | - GetAllProperties() on a non-existing object does not result in a failure currently | |
846 | - port to sd-resolve for connecting to TCP dbus servers | |
847 | - 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 | |
848 | - see if we can drop more message validation on the sending side | |
849 | - add API to clone sd_bus_message objects | |
850 | - longer term: priority inheritance | |
851 | - dbus spec updates: | |
852 | - NameLost/NameAcquired obsolete | |
853 | - GVariant | |
854 | - path escaping | |
855 | - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now | |
856 | ||
857 | * sd-event | |
858 | - allow multiple signal handlers per signal? | |
859 | - document chaining of signal handler for SIGCHLD and child handlers | |
860 | - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ... | |
861 | ||
862 | * investigate endianness issues of UUID vs. GUID | |
863 | ||
864 | * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we | |
865 | should be able to safely try another attempt when the bus call LoadUnit() is invoked. | |
866 | ||
867 | * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login. | |
868 | ||
869 | * add a pam module that on password changes updates any LUKS slot where the password matches | |
870 | ||
871 | * test/: | |
872 | - add unit tests for config_parse_device_allow() | |
873 | ||
874 | * seems that when we follow symlinks to units we prefer the symlink | |
875 | destination path over /etc and /usr. We should not do that. Instead | |
876 | /etc should always override /run+/usr and also any symlink | |
877 | destination. | |
878 | ||
879 | * when isolating, try to figure out a way how we implicitly can order | |
880 | all units we stop before the isolating unit... | |
881 | ||
882 | * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off}) | |
883 | ||
884 | * Add ConditionDirectoryNotEmpty= handle non-absoute paths as a search path or add | |
885 | ConditionConfigSearchPathNotEmpty= or different syntax? See the discussion starting at | |
886 | https://github.com/systemd/systemd/pull/15109#issuecomment-607740136. | |
887 | ||
888 | * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify | |
889 | that the boot loader should be installed to the ESP. Define a way | |
890 | how an installer can figure out whether a BLS compliant boot loader | |
891 | is installed. | |
892 | ||
893 | * think about requeuing jobs when daemon-reload is issued? usecase: | |
894 | the initrd issues a reload after fstab from the host is accessible | |
895 | and we might want to requeue the mounts local-fs acquired through | |
896 | that automatically. | |
897 | ||
898 | * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep() | |
899 | ||
900 | * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good | |
901 | ||
902 | * shutdown logging: store to EFI var, and store to USB stick? | |
903 | ||
904 | * merge unit_kill_common() and unit_kill_context() | |
905 | ||
906 | * EFI: | |
907 | - honor language efi variables for default language selection (if there are any?) | |
908 | - honor timezone efi variables for default timezone selection (if there are any?) | |
909 | - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables | |
910 | * bootctl | |
911 | - recognize the case when not booted on EFI | |
912 | ||
913 | * maybe do not install getty@tty1.service symlink in /etc but in /usr? | |
914 | ||
915 | * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word | |
916 | ||
917 | * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units. | |
918 | ||
919 | * logind: | |
920 | - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around | |
921 | - logind: wakelock/opportunistic suspend support | |
922 | - Add pretty name for seats in logind | |
923 | - logind: allow showing logout dialog from system? | |
924 | - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly. | |
925 | - if pam_systemd is invoked by su from a process that is outside of a | |
926 | any session we should probably just become a NOP, since that's | |
927 | usually not a real user session but just some system code that just | |
928 | needs setuid(). | |
929 | - logind: make the Suspend()/Hibernate() bus calls wait for the for | |
930 | the job to be completed. before returning, so that clients can wait | |
931 | for "systemctl suspend" to finish to know when the suspending is | |
932 | complete. | |
933 | - logind: when the power button is pressed short, just popup a | |
934 | logout dialog. If it is pressed for 1s, do the usual | |
935 | shutdown. Inspiration are Macs here. | |
936 | - expose "Locked" property on logind sesison objects | |
937 | - maybe allow configuration of the StopTimeout for session scopes | |
938 | - rename session scope so that it includes the UID. THat way | |
939 | the session scope can be arranged freely in slices and we don't have | |
940 | make assumptions about their slice anymore. | |
941 | - follow PropertiesChanged state more closely, to deal with quick logouts and | |
942 | relogins | |
943 | - (optionally?) spawn seat-manager@$SEAT.service whenever a seat shows up that as CanGraphical set | |
944 | ||
945 | * journal: | |
946 | - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields | |
947 | - journald: also get thread ID from client, plus thread name | |
948 | - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups | |
949 | - add API to close/reopen/get fd for journal client fd in libsystemd-journal. | |
950 | - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively? | |
951 | - declare the local journal protocol stable in the wiki interface chart | |
952 | - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg | |
953 | - journald: when dropping msgs due to ratelimit make sure to write | |
954 | "dropped %u messages" not only when we are about to print the next | |
955 | message that works, but already after a short timeout | |
956 | - check if we can make journalctl by default use --follow mode inside of less if called without args? | |
957 | - maybe add API to send pairs of iovecs via sd_journal_send | |
958 | - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access | |
959 | - journactl: support negative filtering, i.e. FOOBAR!="waldo", | |
960 | and !FOOBAR for events without FOOBAR. | |
961 | - journal: store timestamp of journal_file_set_offline() int he header, | |
962 | so it is possible to display when the file was last synced. | |
963 | - 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. | |
964 | - journal: find a way to allow dropping history early, based on priority, other rules | |
965 | - journal: When used on NFS, check payload hashes | |
966 | - journald: add kernel cmdline option to disable ratelimiting for debug purposes | |
967 | - refuse taking lower-case variable names in sd_journal_send() and friends. | |
968 | - journald: we currently rotate only after MaxUse+MaxFilesize has been reached. | |
969 | - journal: deal nicely with byte-by-byte copied files, especially regards header | |
970 | - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit | |
971 | - Replace utmp, wtmp, btmp, and lastlog completely with journal | |
972 | - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax? | |
973 | - when a kernel driver logs in a tight loop, we should ratelimit that too. | |
974 | - journald: optionally, log debug messages to /run but everything else to /var | |
975 | - journald: when we drop syslog messages because the syslog socket is | |
976 | full, make sure to write how many messages are lost as first thing | |
977 | to syslog when it works again. | |
978 | - journald: allow per-priority and per-service retention times when rotating/vacuuming | |
979 | - journald: make use of uid-range.h to managed uid ranges to split | |
980 | journals in. | |
981 | - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so... | |
982 | - improve journalctl performance by loading journal files | |
983 | lazily. Encode just enough information in the file name, so that we | |
984 | do not have to open it to know that it is not interesting for us, for | |
985 | the most common operations. | |
986 | - man: document that corrupted journal files is nothing to act on | |
987 | - rework journald sigbus stuff to use mutex | |
988 | - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our | |
989 | services that run under their own user ids, and use User= (but only | |
990 | in a world where userns is ubiquitous since otherwise we cannot | |
991 | invoke those daemons on the host AND in a container anymore). Also, | |
992 | if LimitNPROC= is used without User= we should warn and refuse | |
993 | operation. | |
994 | - journalctl --verify: don't show files that are currently being | |
995 | written to as FAIL, but instead show that their are being written to. | |
996 | - add journalctl -H that talks via ssh to a remote peer and passes through | |
997 | binary logs data | |
998 | - add a version of --merge which also merges /var/log/journal/remote | |
999 | - journalctl: -m should access container journals directly by enumerating | |
1000 | them via machined, and also watch containers coming and going. | |
1001 | Benefit: nspawn --ephemeral would start working nicely with the journal. | |
1002 | - assign MESSAGE_ID to log messages about failed services | |
1003 | ||
1004 | * add a test if all entries in the catalog are properly formatted. | |
1005 | (Adding dashes in a catalog entry currently results in the catalog entry | |
1006 | being silently skipped. journalctl --update-catalog must warn about this, | |
1007 | and we should also have a unit test to check that all our message are OK.) | |
1008 | ||
1009 | * document: | |
1010 | - document that deps in [Unit] sections ignore Alias= fields in | |
1011 | [Install] units of other units, unless those units are disabled | |
1012 | - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets | |
1013 | - document that service reload may be implemented as service reexec | |
1014 | - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr. | |
1015 | - document systemd-journal-flush.service properly | |
1016 | - documentation: recommend to connect the timer units of a service to the service via Also= in [Install] | |
1017 | - man: document the very specific env the shutdown drop-in tools live in | |
1018 | - man: add more examples to man pages | |
1019 | - man: maybe sort directives in man pages, and take sections from --help and apply them to man too | |
1020 | - document root=gpt-auto properly | |
1021 | ||
1022 | * systemctl: | |
1023 | - add systemctl switch to dump transaction without executing it | |
1024 | - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done | |
1025 | - "systemctl disable" on a static unit prints no message and does | |
1026 | nothing. "systemctl enable" does nothing, and gives a bad message | |
1027 | about it. Should fix both to print nice actionable messages. | |
1028 | - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service | |
1029 | - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible | |
1030 | - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards? | |
1031 | - systemctl: "Journal has been rotated since unit was started." message is misleading | |
1032 | - systemctl status output should include list of triggering units and their status | |
1033 | ||
1034 | * unit install: | |
1035 | - "systemctl mask" should find all names by which a unit is accessible | |
1036 | (i.e. by scanning for symlinks to it) and link them all to /dev/null | |
1037 | ||
1038 | * timer units: | |
1039 | - timer units should get the ability to trigger when: | |
1040 | o DST changes | |
1041 | - Modulate timer frequency based on battery state | |
1042 | ||
1043 | * add libsystemd-password or so to query passwords during boot using the password agent logic | |
1044 | ||
1045 | * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed | |
1046 | ||
1047 | * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel | |
1048 | ||
1049 | * make repeated alt-ctrl-del presses printing a dump | |
1050 | ||
1051 | * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ... | |
1052 | ||
1053 | * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not | |
1054 | ||
1055 | * nspawn: | |
1056 | - emulate /dev/kmsg using CUSE and turn off the syslog syscall | |
1057 | with seccomp. That should provide us with a useful log buffer that | |
1058 | systemd can log to during early boot, and disconnect container logs | |
1059 | from the kernel's logs. | |
1060 | - as soon as networkd has a bus interface, hook up --network-interface=, | |
1061 | --network-bridge= with networkd, to trigger netdev creation should an | |
1062 | interface be missing | |
1063 | - a nice way to boot up without machine id set, so that it is set at boot | |
1064 | automatically for supporting --ephemeral. Maybe hash the host machine id | |
1065 | together with the machine name to generate the machine id for the container | |
1066 | - fix logic always print a final newline on output. | |
1067 | https://github.com/systemd/systemd/pull/272#issuecomment-113153176 | |
1068 | - should optionally support receiving WATCHDOG=1 messages from its payload | |
1069 | PID 1... | |
1070 | - optionally automatically add FORWARD rules to iptables whenever nspawn is | |
1071 | running, remove them when shut down. | |
1072 | ||
1073 | * dissect | |
1074 | - refuse mounting over a mount point | |
1075 | - automatically discover .roothash files in dissect, similarly to nspawn | |
1076 | ||
1077 | * machined: | |
1078 | - add an API so that libvirt-lxc can inform us about network interfaces being | |
1079 | removed or added to an existing machine | |
1080 | - "machinectl migrate" or similar to copy a container from or to a | |
1081 | difference host, via ssh | |
1082 | - introduce systemd-nspawn-ephemeral@.service, and hook it into | |
1083 | "machinectl start" with a new --ephemeral switch | |
1084 | - "machinectl status" should also show internal logs of the container in | |
1085 | question | |
1086 | - "machinectl history" | |
1087 | - "machinectl diff" | |
1088 | - "machinectl commit" that takes a writable snapshot of a tree, invokes a | |
1089 | shell in it, and marks it read-only after use | |
1090 | ||
1091 | * cryptsetup: | |
1092 | - cryptsetup-generator: allow specification of passwords in crypttab itself | |
1093 | - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator | |
1094 | ||
1095 | * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it | |
1096 | https://bugs.freedesktop.org/show_bug.cgi?id=54712 | |
1097 | ||
1098 | * add a dependency on standard-conf.xml and other included files to man pages | |
1099 | ||
1100 | * MountFlags=shared acts as MountFlags=slave right now. | |
1101 | ||
1102 | * properly handle loop back mounts via fstab, especially regards to fsck/passno | |
1103 | ||
1104 | * initialize the hostname from the fs label of /, if /etc/hostname does not exist? | |
1105 | ||
1106 | * udev: | |
1107 | - move to LGPL | |
1108 | - kill scsi_id | |
1109 | - add trigger --subsystem-match=usb/usb_device device | |
1110 | - reimport udev db after MOVE events for devices without dev_t | |
1111 | ||
1112 | * There's currently no way to cancel fsck (used to be possible via C-c or c on the console) | |
1113 | ||
1114 | * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/ | |
1115 | ||
1116 | * coredump: | |
1117 | - save coredump in Windows/Mozilla minidump format | |
1118 | - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps | |
1119 | ||
1120 | * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting) | |
1121 | ||
1122 | * be able to specify a forced restart of service A where service B depends on, in case B | |
1123 | needs to be auto-respawned? | |
1124 | ||
1125 | * tmpfiles: | |
1126 | - apply "x" on "D" too (see patch from William Douglas) | |
1127 | - instead of ignoring unknown fields, reject them. | |
1128 | - creating new directories/subvolumes/fifos/device nodes | |
1129 | should not follow symlinks. None of the other adjustment or creation | |
1130 | calls follow symlinks. | |
1131 | ||
1132 | * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early | |
1133 | ||
1134 | * verify that the AF_UNIX sockets of a service in the fs still exist | |
1135 | when we start a service in order to avoid confusion when a user | |
1136 | assumes starting a service is enough to make it accessible | |
1137 | ||
1138 | * Make it possible to set the keymap independently from the font on | |
1139 | the kernel cmdline. Right now setting one resets also the other. | |
1140 | ||
1141 | * and a dbus call to generate target from current state | |
1142 | ||
1143 | * write blog stories about: | |
1144 | - hwdb: what belongs into it, lsusb | |
1145 | - enabling dbus services | |
1146 | - how to make changes to sysctl and sysfs attributes | |
1147 | - remote access | |
1148 | - how to pass throw-away units to systemd, or dynamically change properties of existing units | |
1149 | - testing with Harald's awesome test kit | |
1150 | - auto-restart | |
1151 | - how to develop against journal browsing APIs | |
1152 | - the journal HTTP iface | |
1153 | - non-cgroup resource management | |
1154 | - dynamic resource management with cgroups | |
1155 | - refreshed, longer missions statement | |
1156 | - calendar time events | |
1157 | - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell | |
1158 | - how to create your own target | |
1159 | - instantiated apache, dovecot and so on | |
1160 | - hooking a script into various stages of shutdown/rearly booot | |
1161 | ||
1162 | * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support. | |
1163 | ||
1164 | * dot output for --test showing the 'initial transaction' | |
1165 | ||
1166 | * pid1: | |
1167 | - When logging about multiple units (stopping BoundTo units, conflicts, etc.), | |
1168 | log both units as UNIT=, so that journalctl -u triggers on both. | |
1169 | - generate better errors when people try to set transient properties | |
1170 | that are not supported... | |
1171 | http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html | |
1172 | - maybe introduce WantsMountsFor=? Usecase: | |
1173 | http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html | |
1174 | - recreate systemd's D-Bus private socket file on SIGUSR2 | |
1175 | - move PAM code into its own binary | |
1176 | - when we automatically restart a service, ensure we restart its rdeps, too. | |
1177 | - hide PAM options in fragment parser when compile time disabled | |
1178 | - Support --test based on current system state | |
1179 | - 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(). | |
1180 | - after deserializing sockets in socket.c we should reapply sockopts and things | |
1181 | - drop PID 1 reloading, only do reexecing (difficult: Reload() | |
1182 | currently is properly synchronous, Reexec() is weird, because we | |
1183 | cannot delay the response properly until we are back, so instead of | |
1184 | being properly synchronous we just keep open the fd and close it | |
1185 | when done. That means clients do not get a successful method reply, | |
1186 | but much rather a disconnect on success. | |
1187 | - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr | |
1188 | - when a bus name of a service disappears from the bus make sure to queue further activation requests | |
1189 | ||
1190 | * unit files: | |
1191 | - allow port=0 in .socket units | |
1192 | - maybe introduce ExecRestartPre= | |
1193 | - add ReloadSignal= for configuring a reload signal to use | |
1194 | - implement Register= switch in .socket units to enable registration | |
1195 | in Avahi, RPC and other socket registration services. | |
1196 | - allow Type=simple with PIDFile= | |
1197 | https://bugzilla.redhat.com/show_bug.cgi?id=723942 | |
1198 | - allow writing multiple conditions in unit files on one line | |
1199 | - introduce Type=pid-file | |
1200 | - introduce mix of BindTo and Requisite | |
1201 | - add a concept of RemainAfterExit= to scope units | |
1202 | - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely | |
1203 | - add verification of [Install] section to systemd-analyze verify | |
1204 | ||
1205 | * udev-link-config: | |
1206 | - Make sure ID_PATH is always exported and complete for | |
1207 | network devices where possible, so we can safely rely | |
1208 | on Path= matching | |
1209 | ||
1210 | * sd-rtnl: | |
1211 | - add support for more attribute types | |
1212 | - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places | |
1213 | ||
1214 | * networkd: | |
1215 | - add more keys to [Route] and [Address] sections | |
1216 | - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config) | |
1217 | - add reduced [Link] support to .network files | |
1218 | - properly handle routerless dhcp leases | |
1219 | - work with non-Ethernet devices | |
1220 | - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from? | |
1221 | - the DHCP lease data (such as NTP/DNS) is still made available when | |
1222 | a carrier is lost on a link. It should be removed instantly. | |
1223 | - expose in the API the following bits: | |
1224 | - option 15, domain name | |
1225 | - option 12, hostname and/or option 81, fqdn | |
1226 | - option 123, 144, geolocation | |
1227 | - option 252, configure http proxy (PAC/wpad) | |
1228 | - provide a way to define a per-network interface default metric value | |
1229 | for all routes to it. possibly a second default for DHCP routes. | |
1230 | - allow Name= to be specified repeatedly in the [Match] section. Maybe also | |
1231 | support Name=foo*|bar*|baz ? | |
1232 | - duplicate address check for static IPs (like ARPCHECK in network-scripts) | |
1233 | - whenever uplink info changes, make DHCP server send out FORCERENEW | |
1234 | ||
1235 | * Figure out how to do unittests of networkd's state serialization | |
1236 | ||
1237 | * dhcp: | |
1238 | - figure out how much we can increase Maximum Message Size | |
1239 | ||
1240 | * dhcp6: | |
1241 | - add functions to set previously stored IPv6 addresses on startup and get | |
1242 | them at shutdown; store them in client->ia_na | |
1243 | - write more test cases | |
1244 | - implement reconfigure support, see 5.3., 15.11. and 22.20. | |
1245 | - implement support for temporary adressess (IA_TA) | |
1246 | - implement dhcpv6 authentication | |
1247 | - investigate the usefulness of Confirm messages; i.e. are there any | |
1248 | situations where the link changes without any loss in carrier detection | |
1249 | or interface down | |
1250 | - some servers don't do rapid commit without a filled in IA_NA, verify | |
1251 | this behavior | |
1252 | - RouteTable= ? | |
1253 | ||
1254 | External: | |
1255 | ||
1256 | * dbus: | |
1257 | - natively watch for dbus-*.service symlinks (PENDING) | |
1258 | - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service | |
1259 | ||
1260 | * make cryptsetup lower --iter-time | |
1261 | ||
1262 | * kernel: add device_type = "fb", "fbcon" to class "graphics" | |
1263 | ||
1264 | * /usr/bin/service should actually show the new command line | |
1265 | ||
1266 | * 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= | |
1267 | ||
1268 | * neither pkexec nor sudo initialize environ[] from the PAM environment? | |
1269 | ||
1270 | * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it | |
1271 | ||
1272 | * register catalog database signature as file magic | |
1273 | ||
1274 | * zsh shell completion: | |
1275 | - <command> <verb> -<TAB> should complete options, but currently does not | |
1276 | - systemctl add-wants,add-requires | |
1277 | ||
1278 | * systemctl status should know about 'systemd-analyze calendar ... --iterations=' | |
1279 | * If timer has just OnInactiveSec=..., it should fire after a specified time | |
1280 | after being started. | |
1281 | ||
1282 | Regularly: | |
1283 | ||
1284 | * look for close() vs. close_nointr() vs. close_nointr_nofail() | |
1285 | ||
1286 | * check for strerror(r) instead of strerror(-r) | |
1287 | ||
1288 | * pahole | |
1289 | ||
1290 | * set_put(), hashmap_put() return values check. i.e. == 0 does not free()! | |
1291 | ||
1292 | * use secure_getenv() instead of getenv() where appropriate | |
1293 | ||
1294 | * link up selected blog stories from man pages and unit files Documentation= fields | |
1295 | String is not UTF-8 clean, ignoring assignment |
