---|---|---|
1 | Bugfixes: | |
2 | ||
3 | * copy.c: set the right chattrs before copying files and others after | |
4 | ||
5 | * Many manager configuration settings that are only applicable to user | |
6 | manager or system manager can be always set. It would be better to reject | |
7 | them when parsing config. | |
8 | ||
9 | * Clarify what IPAddress* matches (source, destination, both?) | |
10 | ||
11 | External: | |
12 | ||
13 | * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros. | |
14 | ||
15 | * wiki: update journal format documentation for lz4 additions | |
16 | ||
17 | Janitorial Clean-ups: | |
18 | ||
19 | * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again | |
20 | ||
21 | * rework mount.c and swap.c to follow proper state enumeration/deserialization | |
22 | semantics, like we do for device.c now | |
23 | ||
24 | Features: | |
25 | ||
26 | * when we fork off generators and such, lower LIMIT_NOFILE soft limit to 1K | |
27 | ||
28 | * add a concept for automatically loading per-unit secrets off disk and | |
29 | inserting them into the kernel keyring. Maybe SecretsDirectory= similar to | |
30 | ConfigurationDirectory=. | |
31 | ||
32 | * systemd-gpt-auto: if we find the root dir mounted read-only and the gpt flag | |
33 | doesn't say so generate job that remounts it writable | |
34 | ||
35 | * when no locale is configured, default to UEFI's PlatformLang variable | |
36 | ||
37 | * When logind.conf contains HandleLidSwitch=suspend-then-hibernate and we can't | |
38 | hibernate because the swap partition isn't large enough, still suspend | |
39 | ||
40 | * bootctl: implement Type #2 boot loader entry discovery | |
41 | ||
42 | * bootctl,sd-boot: actually honour the "architecture" key | |
43 | ||
44 | * when a socket unit is spawned with an AF_UNIX path in /var/run, complain and | |
45 | patch it to use /run instead | |
46 | ||
47 | * consider splitting out all temporary file creation APIs (we have so many in | |
48 | fileio.h and elsewhere!) into a new util file of its own. | |
49 | ||
50 | * set memory.oom.group in cgroupsv2 for all leaf cgroups (kernel v4.19+) | |
51 | ||
52 | * drop umask() calls and suchlike from our generators, pid1 should set things up correctly anyway | |
53 | ||
54 | * paranoia: whenever we process passwords, call mlock() on the memory | |
55 | first. i.e. look for all places we use string_erase()/string_free_erase() and | |
56 | augment them with mlock() | |
57 | ||
58 | * whenever oom_kill memory.event event is triggered print a nice log message | |
59 | ||
60 | * Move RestrictAddressFamily= to the new cgroup create socket | |
61 | ||
62 | * support the bind/connect/sendmsg cgroup stuff for sandboxing, and possibly | |
63 | patching around | |
64 | ||
65 | * maybe implicitly attach monotonic+realtime timestamps to outgoing messages in | |
66 | log.c and sd-journal-send | |
67 | ||
68 | * chown() tty a service is attached to after the service goes down | |
69 | ||
70 | * optionally: turn on cgroup delegation for per-session scope units | |
71 | ||
72 | * introduce per-unit (i.e. per-slice, per-service) journal log size limits. | |
73 | ||
74 | * optionally, if a per-partition GPT flag is set for the root/home/… partitions | |
75 | format the partition on next boot and unset the flag, in order to implement | |
76 | factory reset. also, add a second flag that simply indicates whether such a | |
77 | scheme is supported. then, add a tool (or maybe beef up systemd-dissect) to | |
78 | show state of these flags, and optionally trigger such a factory reset on | |
79 | next boot by setting the flag. | |
80 | ||
81 | * sd-boot: search drop-ins in $BOOT, too | |
82 | ||
83 | * sd-boot: add "oneshot boot timeout" variable support | |
84 | ||
85 | * sd-boot: automatically load EFI modules from some drop-in dir, so that people | |
86 | can add in file system drivers and such | |
87 | ||
88 | * esp generator: also mount $BOOT if found | |
89 | ||
90 | * sd-boot: optionally, show boot menu when previous default boot item has | |
91 | non-zero "tries done" count | |
92 | ||
93 | * logind: add "boot into bootmenu" API, and possibly even "boot into windows" | |
94 | and "boot into macos". | |
95 | ||
96 | * bootspec.c: also enumerate EFI unified kernel images. | |
97 | ||
98 | * maybe extend .path units to expose fanotify() per-mount change events | |
99 | ||
100 | * Add a "systemctl list-units --by-slice" mode or so, which rearranges the | |
101 | output of "systemctl list-units" slightly by showing the tree structure of | |
102 | the slices, and the units attached to them. | |
103 | ||
104 | * the a-posteriori stopping of units bound to units that disappeared logic | |
105 | should be reworked: there should be a queue of units, and we should only | |
106 | enqeue stop jobs from a defer event that processes queue instead of | |
107 | right-away when we find a unit that is bound to one that doesn't exist | |
108 | anymore. (similar to how the stop-unneeded queue has been reworked the same | |
109 | way) | |
110 | ||
111 | * nspawn: make nspawn suitable for shell pipelines: instead of triggering a | |
112 | hangup when input is finished, send ^D, which synthesizes an EOF. Then wait | |
113 | for hangup or ^D before passing on the EOF. | |
114 | ||
115 | * When reloading configuration PID 1 should reset all its properties to the | |
116 | original defaults before calling parse_config() | |
117 | ||
118 | * Add OnTimezoneChange= and OnTimeChange= stanzas to .timer units in order to | |
119 | schedule events based on time and timezone changes. | |
120 | ||
121 | * nspawn: greater control over selinux label? | |
122 | ||
123 | * cgroups: figure out if we can somehow communicate in a cleaner way whether a | |
124 | systemd instance not running in the cgroup root shall or shall not manage the | |
125 | attributes of its top-level cgroup. Currently it assumes it manages all, but | |
126 | then might get EPERM due to permission porblems/userns, which is OK, but this | |
127 | should be revisited to make clearer and also work if the payload systemd runs | |
128 | with full privs and without userns. | |
129 | ||
130 | * hibernate/s2h: make this robust and safe to enable in Fedora by default. | |
131 | Specifically: | |
132 | ||
133 | 1. add resume_offset support to the resume code (i.e. support swap files | |
134 | properly) | |
135 | 2. check if swap is on weird storage and refuse if so | |
136 | 3. add autodetection of hibernation images | |
137 | ||
138 | * cgroups: use inotify to get notified when somebody else modifies cgroups | |
139 | owned by us, then log a friendly warning. | |
140 | ||
141 | * beef up log.c with support for stripping ANSI sequences from strings, so that | |
142 | it is OK to include them in log strings. This would be particularly useful so | |
143 | that our log messages could contain clickable links for example for unit | |
144 | files and suchlike we operate on. | |
145 | ||
146 | * add support for "portablectl attach http://foobar.com/waaa.raw (i.e. importd integration) | |
147 | ||
148 | * add attach --enable and attach --now (for attach+enable+start) | |
149 | ||
150 | * sync dynamic uids/gids between host+portable srvice (i.e. if DynamicUser=1 is set for a service, make sure that the | |
151 | selected user is resolvable in the service even if it ships its own /etc/passwd) | |
152 | ||
153 | * Fix DECIMAL_STR_MAX or DECIMAL_STR_WIDTH. One includes a trailing NUL, the | |
154 | other doesn't. What a desaster. Probably to exclude it. Also | |
155 | DECIMAL_STR_WIDTH should probably add an extra "-" into account for negative | |
156 | numbers. | |
157 | ||
158 | * Check that users of inotify's IN_DELETE_SELF flag are using it properly, as | |
159 | usually IN_ATTRIB is the right way to watch deleted files, as the former only | |
160 | fires when a file is actually removed from disk, i.e. the link count drops to | |
161 | zero and is not open anymore, while the latter happens when a file is | |
162 | unlinked from any dir. | |
163 | ||
164 | * port systemctl, busctl, … over to format-table.[ch]'s table formatters | |
165 | ||
166 | * pid1: lock image configured with RootDirectory=/RootImage= using the usual nspawn semantics while the unit is up | |
167 | ||
168 | * add --vacuum-xyz options to coredumpctl, matching those journalctl already has. | |
169 | ||
170 | * SuccessExitStatus= and friends should probably also accept symbolic exit | |
171 | codes names, i.e. error codes from the list maintained in exit-codes.[ch] | |
172 | ||
173 | * introduce Ephemeral= unit file switch, that creates an ephemeral copy of all | |
174 | files and directories that are left writable for a unit, and which are | |
175 | removed after the unit goes down again. A bit like --ephemeral for | |
176 | systemd-nspawn but for system services. If used together with RootImage= this | |
177 | should reflink the image file itself. | |
178 | ||
179 | Related: add Ephemeral=<path1> <path2> … which would allow marking | |
180 | specific paths only like this. | |
181 | ||
182 | * add CopyFile= or so as unit file setting that may be used to copy files or | |
183 | directory trees from the host to te services RootImage= and RootDirectory= | |
184 | environment. Which we can use for /etc/machine-id and in particular | |
185 | /etc/resolv.conf. Should be smart and do something useful on read-only | |
186 | images, for example fallback to read-only bind mounting the file instead. | |
187 | ||
188 | * nspawn's console TTY should be allocated from within the container, not | |
189 | mounted in from the outside | |
190 | ||
191 | * show invocation ID in systemd-run output | |
192 | ||
193 | * bypass SIGTERM state in unit files if KillSignal is SIGKILL | |
194 | ||
195 | * tree-wide: ensure we always block the signals we hook into with | |
196 | sd_event_add_signal() first | |
197 | ||
198 | * add proper dbus APIs for the various sd_notify() commands, such as MAINPID=1 | |
199 | and so on, which would mean we could report errors and such. | |
200 | ||
201 | * teach tmpfiles.d q/Q logic something sensible in the context of XFS/ext4 | |
202 | project quota | |
203 | ||
204 | * introduce DefaultSlice= or so in system.conf that allows changing where we | |
205 | place our units by default, i.e. change system.slice to something | |
206 | else. Similar, ManagerSlice= should exist so that PID1's own scope unit could | |
207 | be moved somewhere else too. Finally machined and logind should get similar | |
208 | options so that it is possible to move user session scopes and machines to a | |
209 | different slice too by default. Usecase: people who want to put resources on | |
210 | the entire system, with the exception of one specific service. See: | |
211 | https://lists.freedesktop.org/archives/systemd-devel/2018-February/040369.html | |
212 | ||
213 | * maybe rework get_user_creds() to query the user database if $SHELL is used | |
214 | for root, but only then. | |
215 | ||
216 | * be stricter with fds we receive for the fdstore: close them asynchronously | |
217 | ||
218 | * calenderspec: add support for week numbers and day numbers within a | |
219 | year. This would allow us to define "bi-weekly" triggers safely. | |
220 | ||
221 | * sd-bus: add vtable flag, that may be used to request client creds implicitly | |
222 | and asynchronously before dispatching the operation | |
223 | ||
224 | * make use of ethtool veth peer info in machined, for automatically finding out | |
225 | host-side interface pointing to the container. | |
226 | ||
227 | * add some special mode to LogsDirectory=/StateDirectory=… that allows | |
228 | declaring these directories without necessarily pulling in deps for them, or | |
229 | creating them when starting up. That way, we could declare that | |
230 | systemd-journald writes to /var/log/journal, which could be useful when we | |
231 | doing disk usage calculations and so on. | |
232 | ||
233 | * taint systemd if there are fewer than 65536 users assigned (userns) to the system. | |
234 | ||
235 | * deprecate RootDirectoryStartOnly= in favour of a new ExecStart= prefix char | |
236 | ||
237 | * add a new RuntimeDirectoryPreserve= mode that defines a similar lifecycle for | |
238 | the runtime dir as we maintain for the fdstore: i.e. keep it around as long | |
239 | as the unit is running or has a job queued. | |
240 | ||
241 | * support projid-based quota in machinectl for containers | |
242 | ||
243 | * Add NetworkNamespacePath= to specify a path to a network namespace | |
244 | ||
245 | * maybe use SOURCE_DATE_EPOCH (i.e. the env var the reproducible builds folks | |
246 | introduced) as the RTC epoch, instead of the mtime of NEWS. | |
247 | ||
248 | * add a way to lock down cgroup migration: a boolean, which when set for a unit | |
249 | makes sure the processes in it can never migrate out of it | |
250 | ||
251 | * blog about fd store and restartable services | |
252 | ||
253 | * document Environment=SYSTEMD_LOG_LEVEL=debug drop-in in debugging document | |
254 | ||
255 | * rework ExecOutput and ExecInput enums so that EXEC_OUTPUT_NULL loses its | |
256 | magic meaning and is no longer upgraded to something else if set explicitly. | |
257 | ||
258 | * in the long run: permit a system with /etc/machine-id linked to /dev/null, to | |
259 | make it lose its identity, i.e. be anonymous. For this we'd have to patch | |
260 | through the whole tree to make all code deal with the case where no machine | |
261 | ID is available. | |
262 | ||
263 | * optionally, collect cgroup resource data, and store it in per-unit RRD files, | |
264 | suitable for processing with rrdtool. Add bus API to access this data, and | |
265 | possibly implement a CPULoad property based on it. | |
266 | ||
267 | * beef up pam_systemd to take unit file settings such as cgroups properties as | |
268 | parameters | |
269 | ||
270 | * a new "systemd-analyze security" tool outputting a checklist of security | |
271 | features a service does and does not implement | |
272 | ||
273 | * maybe hook of xfs/ext4 quotactl() with services? i.e. automatically manage | |
274 | the quota of a the user indicated in User= via unit file settings, like the | |
275 | other resource management concepts. Would mix nicely with DynamicUser=1. Or | |
276 | alternatively, do this with projids, so that we can also cover services | |
277 | running as root. Quota should probably cover all the special dirs such as | |
278 | StateDirectory=, LogsDirectory=, CacheDirectory=, as well as RootDirectory= if it | |
279 | is set, plus the whole disk space any image configured with RootImage=. | |
280 | ||
281 | * Introduce "exit" as an EmergencyAction value, and allow to configure a | |
282 | per-unit success/failure exit code to configure. This would be useful for | |
283 | running commands inside of services inside of containers, which could then | |
284 | propagate their failure state all the way up. | |
285 | ||
286 | * In DynamicUser= mode: before selecting a UID, use disk quota APIs on relevant | |
287 | disks to see if the UID is already in use. | |
288 | ||
289 | * add "systemctl wait" or so, which does what "systemd-run --wait" does, but | |
290 | for all units. It should be both a way to pin units into memory as well as a | |
291 | wait to retrieve their exit data. | |
292 | ||
293 | * expose IO accounting data on the bus, show it in systemd-run --wait and log | |
294 | about it in the resource log message | |
295 | ||
296 | * add "systemctl purge" for flushing out configuration, state, logs, ... of a | |
297 | unit when it is stopped | |
298 | ||
299 | * show whether a service has out-of-date configuration in "systemctl status" by | |
300 | using mtime data of ConfigurationDirectory=. | |
301 | ||
302 | * replace all uses of fgets() + LINE_MAX by read_line() | |
303 | ||
304 | * Add AddUser= setting to unit files, similar to DynamicUser=1 which however | |
305 | creates a static, persistent user rather than a dynamic, transient user. We | |
306 | can leverage code from sysusers.d for this. | |
307 | ||
308 | * add some optional flag to ReadWritePaths= and friends, that has the effect | |
309 | that we create the dir in question when the service is started. Example: | |
310 | ||
311 | ReadWritePaths=:/var/lib/foobar | |
312 | ||
313 | * maybe add call sd_journal_set_block_timeout() or so to set SO_SNDTIMEO for | |
314 | the sd-journal logging socket, and, if the timeout is set to 0, sets | |
315 | O_NONBLOCK on it. That way people can control if and when to block for | |
316 | logging. | |
317 | ||
318 | * hostnamed: populate form factor data from a new hwdb database, so that old | |
319 | yogas can be recognized as "convertible" too, even if they predate the DMI | |
320 | "convertible" form factor | |
321 | ||
322 | * Maybe add a small tool invoked early at boot, that adds in or resizes | |
323 | partitions automatically, to be used when the media used is actually larger | |
324 | than the image written onto it is. | |
325 | ||
326 | * Maybe add PrivatePIDs= as new unit setting, and do minimal PID namespacing | |
327 | after all. Be strict however, only support the equivalent of nspawn's | |
328 | --as-pid2 switch, and sanely proxy sd_notify() messages dropping stuff such | |
329 | as MAINPID. | |
330 | ||
331 | * Add ExecMonitor= setting. May be used multiple times. Forks off a process in | |
332 | the service cgroup, which is supposed to monitor the service, and when it | |
333 | exits the service is considered failed by its monitor. | |
334 | ||
335 | * track the per-service PAM process properly (i.e. as an additional control | |
336 | process), so that it may be queried on the bus and everything. | |
337 | ||
338 | * add a new "debug" job mode, that is propagated to unit_start() and for | |
339 | services results in two things: we raise SIGSTOP right before invoking | |
340 | execve() and turn off watchdog support. Then, use that to implement | |
341 | "systemd-gdb" for attaching to the start-up of any system service in its | |
342 | natural habitat. | |
343 | ||
344 | * maybe introduce gpt auto discovery for /var/tmp? | |
345 | ||
346 | * maybe add gpt-partition-based user management: each user gets his own | |
347 | LUKS-encrypted GPT partition with a new GPT type. A small nss module | |
348 | enumerates users via udev partition enumeration. UIDs are assigned in a fixed | |
349 | way: the partition index is added as offset to some fixed base uid. User name | |
350 | is stored in GPT partition name. A PAM module authenticates the user via the | |
351 | LUKS partition password. Benefits: strong per-user security, compatibility | |
352 | with stateless/read-only/verity-enabled root. (other idea: do this based on | |
353 | loopback files in /home, without GPT involvement) | |
354 | ||
355 | * gpt-auto logic: introduce support for discovering /var matching an image. For | |
356 | that, use a partition type UUID that is hashed from the OS name (as encoded | |
357 | in /etc/os-release), the architecture, and 4 new bits from the gpt flags | |
358 | field of the root partition. This way can easily support multiple OS | |
359 | installations on the same GPT partition table, without problems with | |
360 | unmatched /var partitions. | |
361 | ||
362 | * gpt-auto logic: related to the above, maybe support a "secondary" root | |
363 | partition, that is mounted to / and is writable, and where the actual root's | |
364 | /usr is mounted into. | |
365 | ||
366 | * 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 | |
367 | ||
368 | * drop nss-myhostname in favour of nss-resolve? | |
369 | ||
370 | * add a percentage syntax for TimeoutStopSec=, e.g. TimeoutStopSec=150%, and | |
371 | then use that for the setting used in user@.service. It should be understood | |
372 | relative to the configured default value. | |
373 | ||
374 | * in networkd, when matching device types, fix up DEVTYPE rubbish the kernel passes to us | |
375 | ||
376 | * enable LockMLOCK to take a percentage value relative to physical memory | |
377 | ||
378 | * Permit masking specific netlink APIs with RestrictAddressFamily= | |
379 | ||
380 | * nspawn: support that /proc, /sys/, /dev are pre-mounted | |
381 | ||
382 | * define gpt header bits to select volatility mode | |
383 | ||
384 | * ProtectKernelLogs= (drops CAP_SYSLOG, add seccomp for syslog() syscall, and DeviceAllow to /dev/kmsg) in service files | |
385 | ||
386 | * ProtectClock= (drops CAP_SYS_TIMES, adds seecomp filters for settimeofday, adjtimex), sets DeviceAllow o /dev/rtc | |
387 | ||
388 | * ProtectTracing= (drops CAP_SYS_PTRACE, blocks ptrace syscall, makes /sys/kernel/tracing go away) | |
389 | ||
390 | * ProtectMount= (drop mount/umount/pivot_root from seccomp, disallow fuse via DeviceAllow, imply Mountflags=slave) | |
391 | ||
392 | * ProtectKeyRing= to take keyring calls away | |
393 | ||
394 | * RemoveKeyRing= to remove all keyring entries of the specified user | |
395 | ||
396 | * ProtectReboot= that masks reboot() and kexec_load() syscalls, prohibits kill | |
397 | on PID 1 with the relevant signals, and makes relevant files in /sys and | |
398 | /proc (such as the sysrq stuff) unavailable | |
399 | ||
400 | * make sure the ratelimit object can deal with USEC_INFINITY as way to turn off things | |
401 | ||
402 | * journalctl: make sure -f ends when the container indicated by -M terminates | |
403 | ||
404 | * mount: automatically search for "main" partition of an image has multiple | |
405 | partitions | |
406 | ||
407 | * expose the "privileged" flag of ExecCommand on the bus, and open it up to | |
408 | transient units | |
409 | ||
410 | * in nss-systemd, if we run inside of RootDirectory= with PrivateUsers= set, | |
411 | find a way to map the User=/Group= of the service to the right name. This way | |
412 | a user/group for a service only has to exist on the host for the right | |
413 | mapping to work. | |
414 | ||
415 | * add bus API for creating unit files in /etc, reusing the code for transient units | |
416 | ||
417 | * add bus API to remove unit files from /etc | |
418 | ||
419 | * add bus API to retrieve current unit file contents (i.e. implement "systemctl cat" on the bus only) | |
420 | ||
421 | * rework fopen_temporary() to make use of open_tmpfile_linkable() (problem: the | |
422 | kernel doesn't support linkat() that replaces existing files, currently) | |
423 | ||
424 | * transient units: don't bother with actually setting unit properties, we | |
425 | reload the unit file anyway | |
426 | ||
427 | * journald: sigbus API via a signal-handler safe function that people may call | |
428 | from the SIGBUS handler | |
429 | ||
430 | * optionally, also require WATCHDOG=1 notifications during service start-up and shutdown | |
431 | ||
432 | * resolved: when routing queries, make sure only look for the *longest* suffix... | |
433 | ||
434 | * delay activation of logind until somebody logs in, or when /dev/tty0 pulls it | |
435 | in or lingering is on (so that containers don't bother with it until PAM is used). also exit-on-idle | |
436 | ||
437 | * cache sd_event_now() result from before the first iteration... | |
438 | ||
439 | * add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction | |
440 | ||
441 | * PID1: find a way how we can reload unit file configuration for | |
442 | specific units only, without reloading the whole of systemd | |
443 | ||
444 | * add an explicit parser for LimitRTPRIO= that verifies | |
445 | the specified range and generates sane error messages for incorrect | |
446 | specifications. | |
447 | ||
448 | * when we detect that there are waiting jobs but no running jobs, do something | |
449 | ||
450 | * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy) | |
451 | ||
452 | * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn) | |
453 | ||
454 | * there's probably something wrong with having user mounts below /sys, | |
455 | as we have for debugfs. for exmaple, src/core/mount.c handles mounts | |
456 | prefixed with /sys generally special. | |
457 | http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html | |
458 | ||
459 | * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline | |
460 | ||
461 | * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date | |
462 | ||
463 | * add a job mode that will fail if a transaction would mean stopping | |
464 | running units. Use this in timedated to manage the NTP service | |
465 | state. | |
466 | http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html | |
467 | ||
468 | * Maybe add support for the equivalent of "ethtool advertise" to .link files? | |
469 | http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html | |
470 | ||
471 | * The udev blkid built-in should expose a property that reflects | |
472 | whether media was sensed in USB CF/SD card readers. This should then | |
473 | be used to control SYSTEMD_READY=1/0 so that USB card readers aren't | |
474 | picked up by systemd unless they contain a medium. This would mirror | |
475 | the behaviour we already have for CD drives. | |
476 | ||
477 | * networkd/udev: implement SR_IOV configuration in .link files: | |
478 | http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html | |
479 | ||
480 | * hostnamectl: show root image uuid | |
481 | ||
482 | * Find a solution for SMACK capabilities stuff: | |
483 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html | |
484 | ||
485 | * "systemctl preset-all" should probably order the unit files it | |
486 | operates on lexicographically before starting to work, in order to | |
487 | ensure deterministic behaviour if two unit files conflict (like DMs | |
488 | do, for example) | |
489 | ||
490 | * synchronize console access with BSD locks: | |
491 | http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html | |
492 | ||
493 | * as soon as we have sender timestamps, revisit coalescing multiple parallel daemon reloads: | |
494 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html | |
495 | ||
496 | * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column | |
497 | ||
498 | * figure out when we can use the coarse timers | |
499 | ||
500 | * add "systemctl start -v foobar.service" that shows logs of a service | |
501 | while the start command runs. This is non-trivial to do without | |
502 | races though, since we should flush out all journal messages before | |
503 | returning from the "systemctl stop". | |
504 | ||
505 | * 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 | |
506 | ||
507 | * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment= | |
508 | ||
509 | * consider showing the unit names during boot up in the status output, not just the unit descriptions | |
510 | ||
511 | * maybe allow timer units with an empty Units= setting, so that they | |
512 | can be used for resuming the system but nothing else. | |
513 | ||
514 | * what to do about udev db binary stability for apps? (raw access is not an option) | |
515 | ||
516 | * man: maybe use the word "inspect" rather than "introspect"? | |
517 | ||
518 | * systemctl: if some operation fails, show log output? | |
519 | ||
520 | * systemctl edit: use equvalent of cat() to insert existing config as a comment, prepended with #. | |
521 | Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc. | |
522 | ||
523 | * exponential backoff in timesyncd when we cannot reach a server | |
524 | ||
525 | * timesyncd: add ugly bus calls to set NTP servers per-interface, for usage by NM | |
526 | ||
527 | * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share.... | |
528 | ||
529 | * systemd.show_status= should probably have a mode where only failed | |
530 | units are shown. | |
531 | ||
532 | * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL | |
533 | (throughout the codebase, not only PID1) | |
534 | ||
535 | * resolved: | |
536 | - mDNS/DNS-SD | |
537 | - service registration | |
538 | - service/domain/types browsing | |
539 | - avahi compat | |
540 | - DNS-SD service registration from socket units | |
541 | - resolved should optionally register additional per-interface LLMNR | |
542 | names, so that for the container case we can establish the same name | |
543 | (maybe "host") for referencing the server, everywhere. | |
544 | - allow clients to request DNSSEC for a single lookup even if DNSSEC is off (?) | |
545 | - hook up resolved with machined-based address resolution | |
546 | ||
547 | * refcounting in sd-resolve is borked | |
548 | ||
549 | * Add a new verb "systemctl top" | |
550 | ||
551 | * add new gpt type for btrfs volumes | |
552 | ||
553 | * support empty /etc boots nicely: | |
554 | - nspawn/gpt-generator: introduce new gpt partition type for /usr | |
555 | ||
556 | * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them. | |
557 | ||
558 | * a way for container managers to turn off getty starting via $container_headless= or so... | |
559 | ||
560 | * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit | |
561 | ||
562 | * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services | |
563 | they run added to the initial transaction and thus confuse Type=idle. | |
564 | ||
565 | * add bus api to query unit file's X fields. | |
566 | ||
567 | * gpt-auto-generator: | |
568 | - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap? | |
569 | - Make /home automount rather than mount? | |
570 | ||
571 | * add generator that pulls in systemd-network from containers when | |
572 | CAP_NET_ADMIN is set, more than the loopback device is defined, even | |
573 | when it is otherwise off | |
574 | ||
575 | * MessageQueueMessageSize= (and suchlike) should use parse_iec_size(). | |
576 | ||
577 | * implement Distribute= in socket units to allow running multiple | |
578 | service instances processing the listening socket, and open this up | |
579 | for ReusePort= | |
580 | ||
581 | * socket units: support creating sockets in different namespace, | |
582 | opening it up for JoinsNamespaceOf=. This would require to fork off | |
583 | a tiny process that joins the namespace and creates/binds the socket | |
584 | and passes this back to PID1 via SCM_RIGHTS. This also could be used | |
585 | to allow Chown/chgrp on sockets without requiring NSS in PID 1. | |
586 | ||
587 | * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze | |
588 | $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls | |
589 | should SIGSTOP all unit processes in a loop until all processes of | |
590 | it are fully stopped. This can later be used for app management by | |
591 | desktop UIs such as gnome-shell to freeze apps that are not visible | |
592 | on screen, not unlike how job control works on the shell | |
593 | ||
594 | * cgroups: | |
595 | - implement per-slice CPUFairScheduling=1 switch | |
596 | - handle jointly mounted controllers correctly | |
597 | - introduce high-level settings for RT budget, swappiness | |
598 | - how to reset dynamically changed unit cgroup attributes sanely? | |
599 | - when reloading configuration, apply new cgroup configuration | |
600 | - when recursively showing the cgroup hierarchy, optionally also show | |
601 | the hierarchies of child processes | |
602 | ||
603 | * transient units: | |
604 | - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt | |
605 | ||
606 | * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk? | |
607 | ||
608 | * when we detect low battery and no AC on boot, show pretty splash and refuse boot | |
609 | ||
610 | * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops | |
611 | ||
612 | * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1 | |
613 | ||
614 | * 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 | |
615 | ||
616 | * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs | |
617 | ||
618 | * If we try to find a unit via a dangling symlink, generate a clean | |
619 | error. Currently, we just ignore it and read the unit from the search | |
620 | path anyway. | |
621 | ||
622 | * refuse boot if /usr/lib/os-release is missing or /etc/machine-id cannot be set up | |
623 | ||
624 | * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted. | |
625 | ||
626 | * load .d/*.conf dropins for device units | |
627 | ||
628 | * allow implementation of InaccessibleDirectories=/ plus | |
629 | ReadOnlyDirectories=... for whitelisting files for a service. | |
630 | ||
631 | * sd-bus: | |
632 | - EBADSLT handling | |
633 | - GetAllProperties() on a non-existing object does not result in a failure currently | |
634 | - port to sd-resolve for connecting to TCP dbus servers | |
635 | - 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 | |
636 | - see if we can drop more message validation on the sending side | |
637 | - add API to clone sd_bus_message objects | |
638 | - longer term: priority inheritance | |
639 | - dbus spec updates: | |
640 | - NameLost/NameAcquired obsolete | |
641 | - GVariant | |
642 | - path escaping | |
643 | - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now | |
644 | ||
645 | * sd-event | |
646 | - allow multiple signal handlers per signal? | |
647 | - document chaining of signal handler for SIGCHLD and child handlers | |
648 | - define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ... | |
649 | - generate a failure of a default event loop is executed out-of-thread | |
650 | ||
651 | * investigate endianness issues of UUID vs. GUID | |
652 | ||
653 | * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we | |
654 | should be able to safely try another attempt when the bus call LoadUnit() is invoked. | |
655 | ||
656 | * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login. | |
657 | ||
658 | * add a pam module that on password changes updates any LUKS slot where the password matches | |
659 | ||
660 | * test/: | |
661 | - add unit tests for config_parse_device_allow() | |
662 | ||
663 | * seems that when we follow symlinks to units we prefer the symlink | |
664 | destination path over /etc and /usr. We should not do that. Instead | |
665 | /etc should always override /run+/usr and also any symlink | |
666 | destination. | |
667 | ||
668 | * when isolating, try to figure out a way how we implicitly can order | |
669 | all units we stop before the isolating unit... | |
670 | ||
671 | * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off}) | |
672 | ||
673 | * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify | |
674 | that the boot loader should be installed to the ESP. Define a way | |
675 | how an installer can figure out whether a BLS compliant boot loader | |
676 | is installed. | |
677 | ||
678 | * think about requeuing jobs when daemon-reload is issued? usecase: | |
679 | the initrd issues a reload after fstab from the host is accessible | |
680 | and we might want to requeue the mounts local-fs acquired through | |
681 | that automatically. | |
682 | ||
683 | * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep() | |
684 | ||
685 | * remove any syslog support from log.c — we probably cannot do this before split-off udev is gone for good | |
686 | ||
687 | * shutdown logging: store to EFI var, and store to USB stick? | |
688 | ||
689 | * merge unit_kill_common() and unit_kill_context() | |
690 | ||
691 | * introduce ExecCondition= in services | |
692 | ||
693 | * EFI: | |
694 | - honor language efi variables for default language selection (if there are any?) | |
695 | - honor timezone efi variables for default timezone selection (if there are any?) | |
696 | - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables | |
697 | ||
698 | * maybe do not install getty@tty1.service symlink in /etc but in /usr? | |
699 | ||
700 | * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word | |
701 | ||
702 | * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units. | |
703 | ||
704 | * logind: | |
705 | - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around | |
706 | - logind: wakelock/opportunistic suspend support | |
707 | - Add pretty name for seats in logind | |
708 | - logind: allow showing logout dialog from system? | |
709 | - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly. | |
710 | - if pam_systemd is invoked by su from a process that is outside of a | |
711 | any session we should probably just become a NOP, since that's | |
712 | usually not a real user session but just some system code that just | |
713 | needs setuid(). | |
714 | - logind: make the Suspend()/Hibernate() bus calls wait for the for | |
715 | the job to be completed. before returning, so that clients can wait | |
716 | for "systemctl suspend" to finish to know when the suspending is | |
717 | complete. | |
718 | - logind: when the power button is pressed short, just popup a | |
719 | logout dialog. If it is pressed for 1s, do the usual | |
720 | shutdown. Inspiration are Macs here. | |
721 | - expose "Locked" property on logind sesison objects | |
722 | - maybe allow configuration of the StopTimeout for session scopes | |
723 | - rename session scope so that it includes the UID. THat way | |
724 | the session scope can be arranged freely in slices and we don't have | |
725 | make assumptions about their slice anymore. | |
726 | - follow PropertiesChanged state more closely, to deal with quick logouts and | |
727 | relogins | |
728 | ||
729 | * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty. | |
730 | ||
731 | * journal: | |
732 | - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields | |
733 | - import and delete pstore filesystem content at startup | |
734 | - journald: also get thread ID from client, plus thread name | |
735 | - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups | |
736 | - add API to close/reopen/get fd for journal client fd in libsystemd-journal. | |
737 | - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively? | |
738 | - declare the local journal protocol stable in the wiki interface chart | |
739 | - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg | |
740 | - journald: when dropping msgs due to ratelimit make sure to write | |
741 | "dropped %u messages" not only when we are about to print the next | |
742 | message that works, but alraedy after a short tiemout | |
743 | - check if we can make journalctl by default use --follow mode inside of less if called without args? | |
744 | - maybe add API to send pairs of iovecs via sd_journal_send | |
745 | - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access | |
746 | - journactl: support negative filtering, i.e. FOOBAR!="waldo", | |
747 | and !FOOBAR for events without FOOBAR. | |
748 | - journal: store timestamp of journal_file_set_offline() int he header, | |
749 | so it is possible to display when the file was last synced. | |
750 | - 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. | |
751 | - journal: find a way to allow dropping history early, based on priority, other rules | |
752 | - journal: When used on NFS, check payload hashes | |
753 | - journald: add kernel cmdline option to disable ratelimiting for debug purposes | |
754 | - refuse taking lower-case variable names in sd_journal_send() and friends. | |
755 | - journald: we currently rotate only after MaxUse+MaxFilesize has been reached. | |
756 | - journal: deal nicely with byte-by-byte copied files, especially regards header | |
757 | - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit | |
758 | - Replace utmp, wtmp, btmp, and lastlog completely with journal | |
759 | - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax? | |
760 | - when a kernel driver logs in a tight loop, we should ratelimit that too. | |
761 | - journald: optionally, log debug messages to /run but everything else to /var | |
762 | - journald: when we drop syslog messages because the syslog socket is | |
763 | full, make sure to write how many messages are lost as first thing | |
764 | to syslog when it works again. | |
765 | - change systemd-journal-flush into a service that stays around during | |
766 | boot, and causes the journal to be moved back to /run on shutdown, | |
767 | so that we do not keep /var busy. This needs to happen synchronously, | |
768 | hence doing this via signals is not going to work. | |
769 | - optionally support running journald from the command line for testing purposes in external projects | |
770 | - journald: allow per-priority and per-service retention times when rotating/vacuuming | |
771 | - journald: make use of uid-range.h to managed uid ranges to split | |
772 | journals in. | |
773 | - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so... | |
774 | - improve journalctl performance by loading journal files | |
775 | lazily. Encode just enough information in the file name, so that we | |
776 | do not have to open it to know that it is not interesting for us, for | |
777 | the most common operations. | |
778 | - man: document that corrupted journal files is nothing to act on | |
779 | - rework journald sigbus stuff to use mutex | |
780 | - Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our | |
781 | services that run under their own user ids, and use User= (but only | |
782 | in a world where userns is ubiquitous since otherwise we cannot | |
783 | invoke those daemons on the host AND in a container anymore). Also, | |
784 | if LimitNPROC= is used without User= we should warn and refuse | |
785 | operation. | |
786 | - journalctl --verify: don't show files that are currently being | |
787 | written to as FAIL, but instead show that their are being written to. | |
788 | - add journalctl -H that talks via ssh to a remote peer and passes through | |
789 | binary logs data | |
790 | - add a version of --merge which also merges /var/log/journal/remote | |
791 | - journalctl: -m should access container journals directly by enumerating | |
792 | them via machined, and also watch containers coming and going. | |
793 | Benefit: nspawn --ephemeral would start working nicely with the journal. | |
794 | - assign MESSAGE_ID to log messages about failed services | |
795 | ||
796 | * add a test if all entries in the catalog are properly formatted. | |
797 | (Adding dashes in a catalog entry currently results in the catalog entry | |
798 | being silently skipped. journalctl --update-catalog must warn about this, | |
799 | and we should also have a unit test to check that all our message are OK.) | |
800 | ||
801 | * document: | |
802 | - document that deps in [Unit] sections ignore Alias= fields in | |
803 | [Install] units of other units, unless those units are disabled | |
804 | - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets | |
805 | - document that service reload may be implemented as service reexec | |
806 | - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr. | |
807 | - document systemd-journal-flush.service properly | |
808 | - documentation: recommend to connect the timer units of a service to the service via Also= in [Install] | |
809 | - man: document the very specific env the shutdown drop-in tools live in | |
810 | - man: add more examples to man pages | |
811 | - man: maybe sort directives in man pages, and take sections from --help and apply them to man too | |
812 | ||
813 | * systemctl: | |
814 | - add systemctl switch to dump transaction without executing it | |
815 | - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done | |
816 | - "systemctl disable" on a static unit prints no message and does | |
817 | nothing. "systemctl enable" does nothing, and gives a bad message | |
818 | about it. Should fix both to print nice actionable messages. | |
819 | - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service | |
820 | - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible | |
821 | - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards? | |
822 | - systemctl: "Journal has been rotated since unit was started." message is misleading | |
823 | - systemctl status output should include list of triggering units and their status | |
824 | ||
825 | * unit install: | |
826 | - "systemctl mask" should find all names by which a unit is accessible | |
827 | (i.e. by scanning for symlinks to it) and link them all to /dev/null | |
828 | ||
829 | * timer units: | |
830 | - timer units should get the ability to trigger when: | |
831 | o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET) | |
832 | o DST changes | |
833 | o timezone changes | |
834 | - Modulate timer frequency based on battery state | |
835 | ||
836 | * add libsystemd-password or so to query passwords during boot using the password agent logic | |
837 | ||
838 | * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed | |
839 | ||
840 | * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel | |
841 | ||
842 | * make repeated alt-ctrl-del presses printing a dump | |
843 | ||
844 | * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ... | |
845 | ||
846 | * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not | |
847 | ||
848 | * nspawn: | |
849 | - emulate /dev/kmsg using CUSE and turn off the syslog syscall | |
850 | with seccomp. That should provide us with a useful log buffer that | |
851 | systemd can log to during early boot, and disconnect container logs | |
852 | from the kernel's logs. | |
853 | - as soon as networkd has a bus interface, hook up --network-interface=, | |
854 | --network-bridge= with networkd, to trigger netdev creation should an | |
855 | interface be missing | |
856 | - a nice way to boot up without machine id set, so that it is set at boot | |
857 | automatically for supporting --ephemeral. Maybe hash the host machine id | |
858 | together with the machine name to generate the machine id for the container | |
859 | - fix logic always print a final newline on output. | |
860 | https://github.com/systemd/systemd/pull/272#issuecomment-113153176 | |
861 | - should optionally support receiving WATCHDOG=1 messages from its payload | |
862 | PID 1... | |
863 | - optionally automatically add FORWARD rules to iptables whenever nspawn is | |
864 | running, remove them when shut down. | |
865 | - maybe make copying of /etc/resolv.conf optional, and skip it if --read-only | |
866 | is used | |
867 | ||
868 | * dissect | |
869 | - refuse mounting over a mount point | |
870 | - automatically discover .roothash files in dissect, similarly to nspawn | |
871 | ||
872 | * machined: | |
873 | - add an API so that libvirt-lxc can inform us about network interfaces being | |
874 | removed or added to an existing machine | |
875 | - "machinectl migrate" or similar to copy a container from or to a | |
876 | difference host, via ssh | |
877 | - introduce systemd-nspawn-ephemeral@.service, and hook it into | |
878 | "machinectl start" with a new --ephemeral switch | |
879 | - "machinectl status" should also show internal logs of the container in | |
880 | question | |
881 | - "machinectl history" | |
882 | - "machinectl diff" | |
883 | - "machinectl commit" that takes a writable snapshot of a tree, invokes a | |
884 | shell in it, and marks it read-only after use | |
885 | ||
886 | * cryptsetup: | |
887 | - cryptsetup-generator: allow specification of passwords in crypttab itself | |
888 | - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator | |
889 | ||
890 | * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it | |
891 | https://bugs.freedesktop.org/show_bug.cgi?id=54712 | |
892 | ||
893 | * add a dependency on standard-conf.xml and other included files to man pages | |
894 | ||
895 | * MountFlags=shared acts as MountFlags=slave right now. | |
896 | ||
897 | * properly handle loop back mounts via fstab, especially regards to fsck/passno | |
898 | ||
899 | * initialize the hostname from the fs label of /, if /etc/hostname does not exist? | |
900 | ||
901 | * udev: | |
902 | - move to LGPL | |
903 | - kill scsi_id | |
904 | - add trigger --subsystem-match=usb/usb_device device | |
905 | - reimport udev db after MOVE events for devices without dev_t | |
906 | ||
907 | * There's currently no way to cancel fsck (used to be possible via C-c or c on the console) | |
908 | ||
909 | * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/ | |
910 | ||
911 | * coredump: | |
912 | - save coredump in Windows/Mozilla minidump format | |
913 | - when truncating coredumps, also log the full size that the process had, and make a metadata field so we can report truncated coredumps | |
914 | ||
915 | * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting) | |
916 | ||
917 | * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max | |
918 | ||
919 | * be able to specify a forced restart of service A where service B depends on, in case B | |
920 | needs to be auto-respawned? | |
921 | ||
922 | * tmpfiles: | |
923 | - apply "x" on "D" too (see patch from William Douglas) | |
924 | - replace F with f+. | |
925 | - instead of ignoring unknown fields, reject them. | |
926 | - creating new directories/subvolumes/fifos/device nodes | |
927 | should not follow symlinks. None of the other adjustment or creation | |
928 | calls follow symlinks. | |
929 | ||
930 | * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early | |
931 | ||
932 | * verify that the AF_UNIX sockets of a service in the fs still exist | |
933 | when we start a service in order to avoid confusion when a user | |
934 | assumes starting a service is enough to make it accessible | |
935 | ||
936 | * Make it possible to set the keymap independently from the font on | |
937 | the kernel cmdline. Right now setting one resets also the other. | |
938 | ||
939 | * and a dbus call to generate target from current state | |
940 | ||
941 | * write blog stories about: | |
942 | - hwdb: what belongs into it, lsusb | |
943 | - enabling dbus services | |
944 | - how to make changes to sysctl and sysfs attributes | |
945 | - remote access | |
946 | - how to pass throw-away units to systemd, or dynamically change properties of existing units | |
947 | - testing with Harald's awesome test kit | |
948 | - auto-restart | |
949 | - how to develop against journal browsing APIs | |
950 | - the journal HTTP iface | |
951 | - non-cgroup resource management | |
952 | - dynamic resource management with cgroups | |
953 | - refreshed, longer missions statement | |
954 | - calendar time events | |
955 | - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell | |
956 | - how to create your own target | |
957 | - instantiated apache, dovecot and so on | |
958 | - hooking a script into various stages of shutdown/rearly booot | |
959 | ||
960 | * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support. | |
961 | ||
962 | * dot output for --test showing the 'initial transaction' | |
963 | ||
964 | * pid1: | |
965 | - When logging about multiple units (stopping BoundTo units, conflicts, etc.), | |
966 | log both units as UNIT=, so that journalctl -u triggers on both. | |
967 | - generate better errors when people try to set transient properties | |
968 | that are not supported... | |
969 | http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html | |
970 | - maybe introduce WantsMountsFor=? Usecase: | |
971 | http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html | |
972 | - recreate systemd's D-Bus private socket file on SIGUSR2 | |
973 | - move PAM code into its own binary | |
974 | - when we automatically restart a service, ensure we restart its rdeps, too. | |
975 | - hide PAM options in fragment parser when compile time disabled | |
976 | - Support --test based on current system state | |
977 | - 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(). | |
978 | - after deserializing sockets in socket.c we should reapply sockopts and things | |
979 | - drop PID 1 reloading, only do reexecing (difficult: Reload() | |
980 | currently is properly synchronous, Reexec() is weird, because we | |
981 | cannot delay the response properly until we are back, so instead of | |
982 | being properly synchronous we just keep open the fd and close it | |
983 | when done. That means clients do not get a successful method reply, | |
984 | but much rather a disconnect on success. | |
985 | - when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr | |
986 | - when a bus name of a service disappears from the bus make sure to queue further activation requests | |
987 | ||
988 | * unit files: | |
989 | - allow port=0 in .socket units | |
990 | - maybe introduce ExecRestartPre= | |
991 | - add ReloadSignal= for configuring a reload signal to use | |
992 | - implement Register= switch in .socket units to enable registration | |
993 | in Avahi, RPC and other socket registration services. | |
994 | - allow Type=simple with PIDFile= | |
995 | https://bugzilla.redhat.com/show_bug.cgi?id=723942 | |
996 | - allow writing multiple conditions in unit files on one line | |
997 | - load-fragment: when loading a unit file via a chain of symlinks | |
998 | verify that it is not masked via any of the names traversed. | |
999 | - introduce Type=pid-file | |
1000 | - introduce mix of BindTo and Requisite | |
1001 | - add a concept of RemainAfterExit= to scope units | |
1002 | - Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely | |
1003 | ||
1004 | * udev-link-config: | |
1005 | - Make sure ID_PATH is always exported and complete for | |
1006 | network devices where possible, so we can safely rely | |
1007 | on Path= matching | |
1008 | - check MTUBytes parsing (expecting size_t but we are using unsigned) | |
1009 | ||
1010 | * sd-rtnl: | |
1011 | - add support for more attribute types | |
1012 | - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places | |
1013 | ||
1014 | * networkd: | |
1015 | - add more keys to [Route] and [Address] sections | |
1016 | - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config) | |
1017 | - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline) | |
1018 | - add reduced [Link] support to .network files | |
1019 | - add Scope= parsing option for [Network] | |
1020 | - properly handle routerless dhcp leases | |
1021 | - work with non-Ethernet devices | |
1022 | - add support for more bond options | |
1023 | - dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from? | |
1024 | - the DHCP lease data (such as NTP/DNS) is still made available when | |
1025 | a carrier is lost on a link. It should be removed instantly. | |
1026 | - expose in the API the following bits: | |
1027 | - option 15, domain name and/or option 119, search list | |
1028 | - option 12, host name and/or option 81, fqdn | |
1029 | - option 123, 144, geolocation | |
1030 | - option 252, configure http proxy (PAC/wpad) | |
1031 | - provide a way to define a per-network interface default metric value | |
1032 | for all routes to it. possibly a second default for DHCP routes. | |
1033 | - allow Name= to be specified repeatedly in the [Match] section. Maybe also | |
1034 | support Name=foo*|bar*|baz ? | |
1035 | - duplicate address check for static IPs (like ARPCHECK in network-scripts) | |
1036 | - allow DUID/IAID to be customized, see issue #394. | |
1037 | - whenever uplink info changes, make DHCP server send out FORCERENEW | |
1038 | ||
1039 | * networkd-wait-online: | |
1040 | - make operstates to wait for configurable? | |
1041 | ||
1042 | * dhcp: | |
1043 | - figure out how much we can increase Maximum Message Size | |
1044 | ||
1045 | * dhcp6: | |
1046 | - add functions to set previously stored IPv6 addresses on startup and get | |
1047 | them at shutdown; store them in client->ia_na | |
1048 | - write more test cases | |
1049 | - implement reconfigure support, see 5.3., 15.11. and 22.20. | |
1050 | - implement support for temporary adressess (IA_TA) | |
1051 | - implement dhcpv6 authentication | |
1052 | - investigate the usefulness of Confirm messages; i.e. are there any | |
1053 | situations where the link changes without any loss in carrier detection | |
1054 | or interface down | |
1055 | - some servers don't do rapid commit without a filled in IA_NA, verify | |
1056 | this behavior | |
1057 | - RouteTable= ? | |
1058 | ||
1059 | External: | |
1060 | ||
1061 | * dbus: | |
1062 | - natively watch for dbus-*.service symlinks (PENDING) | |
1063 | - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service | |
1064 | ||
1065 | * fix alsa mixer restore to not print error when no config is stored | |
1066 | ||
1067 | * make cryptsetup lower --iter-time | |
1068 | ||
1069 | * patch kernel for xattr support in /dev, /proc/, /sys? | |
1070 | ||
1071 | * kernel: add device_type = "fb", "fbcon" to class "graphics" | |
1072 | ||
1073 | * /usr/bin/service should actually show the new command line | |
1074 | ||
1075 | * 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= | |
1076 | ||
1077 | * fedora: F20: go timer units all the way, leave cron.daily for cron | |
1078 | ||
1079 | * neither pkexec nor sudo initialize environ[] from the PAM environment? | |
1080 | ||
1081 | * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it | |
1082 | ||
1083 | * register catalog database signature as file magic | |
1084 | ||
1085 | * zsh shell completion: | |
1086 | - <command> <verb> -<TAB> should complete options, but currently does not | |
1087 | - systemctl add-wants,add-requires | |
1088 | ||
1089 | ||
1090 | Regularly: | |
1091 | ||
1092 | * look for close() vs. close_nointr() vs. close_nointr_nofail() | |
1093 | ||
1094 | * check for strerror(r) instead of strerror(-r) | |
1095 | ||
1096 | * pahole | |
1097 | ||
1098 | * set_put(), hashmap_put() return values check. i.e. == 0 does not free()! | |
1099 | ||
1100 | * use secure_getenv() instead of getenv() where appropriate | |
1101 | ||
1102 | * link up selected blog stories from man pages and unit files Documentation= fields |
