1 | Bugfixes: | |
2 | ||
3 | * Should systemctl status \* work on all unit types, not just .service? | |
4 | ||
5 | * Dangling symlinks of .automount unit files in .wants/ directories, set up | |
6 | automount points even when the original .automount file did not exist | |
7 | anymore. Only the .mount unit was still around. | |
8 | ||
9 | * ExecStart with unicode characters fails in strv_split_extract: | |
10 | ||
11 | [Service] | |
12 | Environment=ONE='one' "TWO='two two' too" THREE= | |
13 | ExecStart=/bin/python3 -c 'import sys;print(sys.argv)' $ONE $TWO $THREE | |
14 | ||
15 | * When systemctl --host is used, underlying ssh connection can remain open. | |
16 | bus_close does not kill children? | |
17 | ||
18 | External: | |
19 | ||
20 | * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros. | |
21 | ||
22 | * wiki: update journal format documentation for lz4 additions | |
23 | ||
24 | Janitorial Clean-ups: | |
25 | ||
26 | * code cleanup: retire FOREACH_WORD_QUOTED, port to extract_first_word() loops instead | |
27 | ||
28 | * replace manual readdir() loops with FOREACH_DIRENT or FOREACH_DIRENT_ALL | |
29 | ||
30 | * Get rid of the last strerror() invocations in favour of %m and strerror_r() | |
31 | ||
32 | * Rearrange tests so that the various test-xyz.c match a specific src/basic/xyz.c again | |
33 | ||
34 | Features: | |
35 | ||
36 | * PID1: find a way how we can reload unit file configuration for | |
37 | specific units only, without reloading the whole of systemd | |
38 | ||
39 | * add an explicit parser for LimitNICE= and LimitRTPRIO= that verifies | |
40 | the specified range and generates sane error messages for incorrect | |
41 | specifications. Also, for LimitNICE= maybe introduce a syntax such | |
42 | as "+5" or "-7" in order to make the limits more readable as they | |
43 | are otherwise shifted by 20. | |
44 | ||
45 | * do something about "/control" subcgroups in the unified cgroup hierarchy | |
46 | ||
47 | * when we detect that there are waiting jobs but no running jobs, do something | |
48 | ||
49 | * push CPUAffinity= also into the "cpuset" cgroup controller (only after the cpuset controller got ported to the unified hierarchy) | |
50 | ||
51 | * add a concept of RemainAfterExit= to scope units | |
52 | ||
53 | * add a new command "systemctl revert" or so, that removes all dropin | |
54 | snippets in /run and /etc, and all unit files with counterparts in | |
55 | /usr, and thus undoes what "systemctl set-property" and "systemctl | |
56 | edit" create. Maybe even add "systemctl revert -a" to do this for | |
57 | all units. | |
58 | ||
59 | * sd-event: maybe add support for inotify events | |
60 | ||
61 | * PID 1 should send out sd_notify("WATCHDOG=1") messages (for usage in the --user mode, and when run via nspawn) | |
62 | ||
63 | * nspawn should send out sd_notify("WATCHDOG=1") messages | |
64 | ||
65 | * nspawn should optionally support receiving WATCHDOG=1 messages from its payload PID 1... | |
66 | ||
67 | * consider throwing a warning if a service declares it wants to be "Before=" a .device unit. | |
68 | ||
69 | * "systemctl edit" should know a mode to create a new unit file | |
70 | ||
71 | * there's probably something wrong with having user mounts below /sys, | |
72 | as we have for debugfs. for exmaple, src/core/mount.c handles mounts | |
73 | prefixed with /sys generally special. | |
74 | http://lists.freedesktop.org/archives/systemd-devel/2015-June/032962.html | |
75 | ||
76 | * nspawn: fix logic always print a final newline on output. | |
77 | https://github.com/systemd/systemd/pull/272#issuecomment-113153176 | |
78 | ||
79 | * man: document that unless you use StandardError=null the shell >/dev/stderr won't work in shell scripts in services | |
80 | ||
81 | * "systemctl daemon-reload" should result in /etc/systemd/system.conf being reloaded by systemd | |
82 | ||
83 | * install: include generator dirs in unit file search paths | |
84 | ||
85 | * logind: follow PropertiesChanged state more closely, to deal with quick logouts and relogins | |
86 | ||
87 | * invent a better systemd-run scheme for naming scopes, that works with remoting | |
88 | ||
89 | * add journalctl -H that talks via ssh to a remote peer and passes through binary logs data | |
90 | ||
91 | * change journalctl -M to acquire fd to journal directory via machined, and then operate on that via openat() instead of absolute paths | |
92 | ||
93 | * add a version of --merge which also merges /var/log/journal/remote | |
94 | ||
95 | * log accumulated resource usage after each service invocation | |
96 | ||
97 | * nspawn: a nice way to boot up without machine id set, so that it is set at boot automatically for supporting --ephemeral. Maybe hash the host machine id together with the machine name to generate the machine id for the container | |
98 | ||
99 | * logind: rename session scope so that it includes the UID. THat way | |
100 | the session scope can be arranged freely in slices and we don't have | |
101 | make assumptions about their slice anymore. | |
102 | ||
103 | * journalctl: -m should access container journals directly by enumerating them via machined, and also watch containers coming and going. Benefit: nspawn --ephemeral would start working nicely with the journal. | |
104 | ||
105 | * nspawn: don't copy /etc/resolv.conf from host into container unless we are in shared-network mode | |
106 | ||
107 | * nspawn: optionally automatically add FORWARD rules to iptables whenever nspawn is running, remove them when shut down. | |
108 | ||
109 | * importd: generate a nice warning if mkfs.btrfs is missing | |
110 | ||
111 | * nspawn: add a logic for cleaning up read-only, hidden container images in /var/lib/machines that are not ancestors of any non-hidden containers | |
112 | ||
113 | * nspawn: Improve error message when --bind= is used on a non-existing source directory | |
114 | ||
115 | * nspawn: maybe make copying of /etc/resolv.conf optional, and skip it if --read-only is used | |
116 | ||
117 | * man: document how update dkr images works with machinectl | |
118 | http://lists.freedesktop.org/archives/systemd-devel/2015-February/028630.html | |
119 | ||
120 | * nspawn: as soon as networkd has a bus interface, hook up --network-interface=, --network-bridge= with networkd, to trigger netdev creation should an interface be missing | |
121 | ||
122 | * rework C11 utf8.[ch] to use char32_t instead of uint32_t when referring | |
123 | to unicode chars, to make things more expressive. | |
124 | ||
125 | * "machinectl migrate" or similar to copy a container from or to a | |
126 | difference host, via ssh | |
127 | ||
128 | * tmpfiles: creating new directories/subvolumes/fifos/device nodes | |
129 | should not follow symlinks. None of the other adjustment or creation | |
130 | calls follow symlinks. | |
131 | ||
132 | * fstab-generator: default to tmpfs-as-root if only usr= is specified on the kernel cmdline | |
133 | ||
134 | * docs: bring http://www.freedesktop.org/wiki/Software/systemd/MyServiceCantGetRealtime up to date | |
135 | ||
136 | * mounting and unmounting mount points manually with different source | |
137 | devices will result in collected collected on all devices used. | |
138 | http://lists.freedesktop.org/archives/systemd-devel/2015-April/030225.html | |
139 | ||
140 | * add a job mode that will fail if a transaction would mean stopping | |
141 | running units. Use this in timedated to manage the NTP service | |
142 | state. | |
143 | http://lists.freedesktop.org/archives/systemd-devel/2015-April/030229.html | |
144 | ||
145 | * Maybe add support for the equivalent of "ethtool advertise" to .link files? | |
146 | http://lists.freedesktop.org/archives/systemd-devel/2015-April/030112.html | |
147 | ||
148 | * .timer units should optionally support CLOCK_BOOTTIME in addition to CLOCK_MONOTONIC | |
149 | ||
150 | * When logging about multiple units (stopping BoundTo units, conflicts, etc.), | |
151 | log both units as UNIT=, so that journalctl -u triggers on both. | |
152 | ||
153 | * to allow "linking" of nspawn containers, extend --network-bridge= so | |
154 | that it can dynamically create bridge interfaces that are refcounted | |
155 | by the containers on them. For each group of containers to link together | |
156 | ||
157 | * journalctl --verify: don't show files that are currently being | |
158 | written to as FAIL, but instead show that their are being written | |
159 | to. | |
160 | ||
161 | * assign MESSAGE_ID to log messages about failed services | |
162 | ||
163 | * coredump: make the handler check /proc/$PID/rlimits for RLIMIT_CORE, | |
164 | and supress coredump if turned off. Then change RLIMIT_CORE to | |
165 | infinity by default for all services. This then allows per-service | |
166 | control of coredumping. | |
167 | ||
168 | * generate better errors when people try to set transient properties | |
169 | that are not supported... | |
170 | http://lists.freedesktop.org/archives/systemd-devel/2015-February/028076.html | |
171 | ||
172 | * maybe introduce WantsMountsFor=? Usecase: | |
173 | http://lists.freedesktop.org/archives/systemd-devel/2015-January/027729.html | |
174 | ||
175 | * The udev blkid built-in should expose a property that reflects | |
176 | whether media was sensed in USB CF/SD card readers. This should then | |
177 | be used to control SYSTEMD_READY=1/0 so that USB card readers aren't | |
178 | picked up by systemd unless they contain a medium. This would mirror | |
179 | the behaviour we already have for CD drives. | |
180 | ||
181 | * nspawn: emulate /dev/kmsg using CUSE and turn off the syslog syscall | |
182 | with seccomp. That should provide us with a useful log buffer that | |
183 | systemd can log to during early boot, and disconnect container logs | |
184 | from the kernel's logs. | |
185 | ||
186 | * networkd/udev: implement SR_IOV configuration in .link files: | |
187 | http://lists.freedesktop.org/archives/systemd-devel/2015-January/027451.html | |
188 | ||
189 | * Set RLIMIT_NPROC for systemd-journal-xyz, and all other of our | |
190 | services that run under their own user ids, and use User= (but only | |
191 | in a world where userns is ubiquitous since otherwise we cannot | |
192 | invoke those daemons on the host AND in a container anymore). Also, | |
193 | if LimitNPROC= is used without User= we should warn and refuse | |
194 | operation. | |
195 | ||
196 | * logind: maybe allow configuration of the StopTimeout for session scopes | |
197 | ||
198 | * Set NoNewPrivileges= on all of our own services, where that makes sense | |
199 | ||
200 | * Rework systemctl's GetAll property parsing to use the generic bus_map_all_properties() API | |
201 | ||
202 | * rework journald sigbus stuff to use mutex | |
203 | ||
204 | * import-dkr: support tarsum checksum verification, if it becomes reality one day... | |
205 | ||
206 | * import-dkr: convert json bits to nspawn configuration | |
207 | ||
208 | * core/cgroup: support net_cls modules, and support automatically allocating class ids, then add support for making firewall changes depending on it, to implement a per-service firewall | |
209 | ||
210 | * introduce systemd-nspawn-ephemeral@.service, and hook it into "machinectl start" with a new --ephemeral switch | |
211 | ||
212 | * "machinectl status" should also show internal logs of the container in question | |
213 | ||
214 | * "machinectl list-images" should show os-release data, as well as machine-info data (including deployment level) | |
215 | ||
216 | * Port various tools to make use of verbs.[ch], where applicable | |
217 | ||
218 | * "machinectl history" | |
219 | ||
220 | * "machinectl diff" | |
221 | ||
222 | * "machinectl commit" that takes a writable snapshot of a tree, invokes a shell in it, and marks it read-only after use | |
223 | ||
224 | * systemd-nspawn -x should support ephemeral instances of gpt images | |
225 | ||
226 | * hostnamectl: show root image uuid | |
227 | ||
228 | * sysfs set api in libudev is not const | |
229 | ||
230 | * Find a solution for SMACK capabilities stuff: | |
231 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/026188.html | |
232 | ||
233 | * "systemctl preset-all" should probably order the unit files it | |
234 | operates on lexicographically before starting to work, in order to | |
235 | ensure deterministic behaviour if two unit files conflict (like DMs | |
236 | do, for example) | |
237 | ||
238 | * resolved should optionally register additional per-interface LLMNR | |
239 | names, so that for the container case we can establish the same name | |
240 | (maybe "host") for referencing the server, everywhere. | |
241 | ||
242 | * systemd-journal-upload (or a new, related tool): allow pushing out | |
243 | journal messages onto the network in BSD syslog protocol, | |
244 | continuously. Default to some link-local IP mcast group, to make this | |
245 | useful as a one-stop debugging tool. | |
246 | ||
247 | * synchronize console access with BSD locks: | |
248 | http://lists.freedesktop.org/archives/systemd-devel/2014-October/024582.html | |
249 | ||
250 | * as soon as we have kdbus, and sender timestamps, revisit coalescing multiple parallel daemon reloads: | |
251 | http://lists.freedesktop.org/archives/systemd-devel/2014-December/025862.html | |
252 | ||
253 | * the install state probably shouldn't get confused by generated units, think dbus1/kdbus compat! | |
254 | ||
255 | * in systemctl list-unit-files: show the install value the presets would suggest for a service in a third column | |
256 | ||
257 | * figure out when we can use the coarse timers | |
258 | ||
259 | * add "systemctl start -v foobar.service" that shows logs of a service | |
260 | while the start command runs. This is non-trivial to do without | |
261 | races though, since we should flush out all journal messages before | |
262 | returning from the "systemctl stop". | |
263 | ||
264 | * 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 | |
265 | ||
266 | * timesyncd + resolved: add ugly bus calls to set NTP and DNS servers per-interface, for usage by NM | |
267 | ||
268 | * add infrastructure to allocate dynamic/transient users and UID ranges, for use in user-namespaced containers, per-seat gdm login screens and gdm guest sessions | |
269 | ||
270 | * machined: add an API so that libvirt-lxc can inform us about network interfaces being removed or added to an existing machine | |
271 | ||
272 | * maybe add support for specifier expansion in user.conf, specifically DefaultEnvironment= | |
273 | ||
274 | * introduce systemd-timesync-wait.service or so to sync on an NTP fix? | |
275 | ||
276 | * systemd --user should issue sd_notify() upon reaching basic.target, not on becoming idle | |
277 | ||
278 | * consider showing the unit names during boot up in the status output, not just the unit descriptions | |
279 | ||
280 | * dhcp: do we allow configuring dhcp routes on interfaces that are not the one we got the dhcp info from? | |
281 | ||
282 | * maybe allow timer units with an empty Units= setting, so that they | |
283 | can be used for resuming the system but nothing else. | |
284 | ||
285 | * what to do about udev db binary stability for apps? (raw access is not an option) | |
286 | ||
287 | * maybe provide an API to allow migration of foreign PIDs into existing scopes. | |
288 | ||
289 | * maybe support a new very "soft" reboot mode, that simply kills all processes, disassembles everything, flushes /run and sysvipc, and then reexecs systemd again | |
290 | ||
291 | * man: document that corrupted journal files is nothing to act on | |
292 | ||
293 | * man: maybe use the word "inspect" rather than "introspect"? | |
294 | ||
295 | * "machinectl list" should probably show columns for OS version and IP addresses | |
296 | ||
297 | * systemctl: if some operation fails, show log output? | |
298 | ||
299 | * systemctl edit: | |
300 | - allow creation of units from scratch | |
301 | - use equvalent of cat() to insert existing config as a comment, prepended with #. | |
302 | Upon editor exit, lines with one # are removed, lines with two # are left with one #, etc. | |
303 | ||
304 | * refcounting in sd-resolve is borked | |
305 | ||
306 | * exponential backoff in timesyncd and resolved when we cannot reach a server | |
307 | ||
308 | * extract_many_words() should probably be used by a lot of code that | |
309 | currently uses FOREACH_WORD and friends. For example, most conf | |
310 | parsing callbacks should use it. | |
311 | ||
312 | * merge ~/.local/share and ~/.local/lib into one similar /usr/lib and /usr/share.... | |
313 | ||
314 | * systemd.show_status= should probably have a mode where only failed | |
315 | units are shown. | |
316 | ||
317 | * add systemd.abort_on_kill or some other such flag to send SIGABRT instead of SIGKILL | |
318 | (throughout the codebase, not only PID1) | |
319 | ||
320 | * networkd: | |
321 | - add LLDP client side support | |
322 | - the DHCP lease data (such as NTP/DNS) is still made available when | |
323 | a carrier is lost on a link. It should be removed instantly. | |
324 | - expose in the API the following bits: | |
325 | - option 15, domain name and/or option 119, search list | |
326 | - option 12, host name and/or option 81, fqdn | |
327 | - option 123, 144, geolocation | |
328 | - option 252, configure http proxy (PAC/wpad) | |
329 | - provide a way to define a per-network interface default metric value | |
330 | for all routes to it. possibly a second default for DHCP routes. | |
331 | - allow Name= to be specified repeatedly in the [Match] section. Maybe also | |
332 | support Name=foo*|bar*|baz ? | |
333 | - duplicate address check for static IPs (like ARPCHECK in network-scripts) | |
334 | - allow DUID/IAID to be customized, see issue #394. | |
335 | - support configuration option for TSO (tcp segmentation offload) | |
336 | - networkd: whenever uplink info changes, make DHCP server send out FORCERENEW | |
337 | ||
338 | * resolved: | |
339 | - put networkd events and rtnl events at a higher priority, so that | |
340 | we always process them before we process client requests | |
341 | - DNSSEC | |
342 | - add display of private key types (http://tools.ietf.org/html/rfc4034#appendix-A.1.1)? | |
343 | - DNS | |
344 | - search paths | |
345 | - mDNS/DNS-SD | |
346 | - avahi compat | |
347 | - DNS-SD service registration from socket units | |
348 | - edns0 | |
349 | - dname: Not necessary for plain DNS as synthesized cname is handed out instead if we do not | |
350 | announce dname support. However, for DNSSEC it is necessary as the synthesized cname | |
351 | will not be signed. | |
352 | - cname on PTR (?) | |
353 | ||
354 | * Allow multiple ExecStart= for all Type= settings, so that we can cover rescue.service nicely | |
355 | ||
356 | * Add a new verb "systemctl top" | |
357 | ||
358 | * add new gpt type for btrfs volumes | |
359 | ||
360 | * support empty /etc boots nicely: | |
361 | - nspawn/gpt-generator: introduce new gpt partition type for /usr | |
362 | - fstab-generator: support systemd.volatile=yes|no|state on the kernel cmdline, too, similar to nspawn's --volatile= | |
363 | ||
364 | * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them. | |
365 | ||
366 | * timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake... | |
367 | ||
368 | * a way for container managers to turn off getty starting via $container_headless= or so... | |
369 | ||
370 | * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit | |
371 | ||
372 | * mount_cgroup_controllers(): symlinks need to get the label applied | |
373 | ||
374 | * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services | |
375 | they run added to the initial transaction and thus confuse Type=idle. | |
376 | ||
377 | * Run most system services with cgroupfs read-only and procfs with a more secure mode (doesn't work, since the hidepid= option is per-pid-namespace, not per-mount) | |
378 | ||
379 | * sd-event: generate a failure of a default event loop is executed out-of-thread | |
380 | ||
381 | * add bus api to query unit file's X fields. | |
382 | ||
383 | * consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup= | |
384 | ||
385 | * sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ... | |
386 | ||
387 | * gpt-auto-generator: | |
388 | - Support LUKS for root devices | |
389 | - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap? | |
390 | - Make /home automount rather than mount? | |
391 | ||
392 | * add generator that pulls in systemd-network from containers when | |
393 | CAP_NET_ADMIN is set, more than the loopback device is defined, even | |
394 | when it is otherwise off | |
395 | ||
396 | * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size(). | |
397 | ||
398 | * "busctl status" works only as root on dbus1, since we cannot read | |
399 | /proc/$PID/exe | |
400 | ||
401 | * implement Distribute= in socket units to allow running multiple | |
402 | service instances processing the listening socket, and open this up | |
403 | for ReusePort= | |
404 | ||
405 | * socket units: support creating sockets in different namespace, | |
406 | opening it up for JoinsNamespaceOf=. This would require to fork off | |
407 | a tiny process that joins the namespace and creates/binds the socket | |
408 | and passes this back to PID1 via SCM_RIGHTS. This also could be used | |
409 | to allow Chown/chgrp on sockets without requiring NSS in PID 1. | |
410 | ||
411 | * New service property: maximum CPU and wallclock runtime for a service | |
412 | ||
413 | * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze | |
414 | $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls | |
415 | should SIGSTOP all unit processes in a loop until all processes of | |
416 | it are fully stopped. This can later be used for app management by | |
417 | desktop UIs such as gnome-shell to freeze apps that are not visible | |
418 | on screen, not unlike how job control works on the shell | |
419 | ||
420 | * cgroups: | |
421 | - implement per-slice CPUFairScheduling=1 switch | |
422 | - handle jointly mounted controllers correctly | |
423 | - introduce high-level settings for RT budget, swappiness | |
424 | - how to reset dynamically changed unit cgroup attributes sanely? | |
425 | - when reloading configuration, apply new cgroup configuration | |
426 | - when recursively showing the cgroup hierarchy, optionally also show | |
427 | the hierarchies of child processes | |
428 | ||
429 | * transient units: | |
430 | - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt | |
431 | - ensure scope units may be started only a single time | |
432 | ||
433 | * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk? | |
434 | ||
435 | * when we detect low battery and no AC on boot, show pretty splash and refuse boot | |
436 | ||
437 | * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus | |
438 | ||
439 | * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops | |
440 | ||
441 | * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1 | |
442 | ||
443 | * unify dispatch table in systemctl_main() and friends | |
444 | ||
445 | * 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 | |
446 | ||
447 | * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs | |
448 | ||
449 | * If we try to find a unit via a dangling symlink, generate a clean | |
450 | error. Currently, we just ignore it and read the unit from the search | |
451 | path anyway. | |
452 | ||
453 | * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up | |
454 | ||
455 | * btrfs raid assembly: some .device jobs stay stuck in the queue | |
456 | ||
457 | * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd | |
458 | ||
459 | * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted. | |
460 | ||
461 | * load .d/*.conf dropins for device units | |
462 | ||
463 | * allow implementation of InaccessibleDirectories=/ plus | |
464 | ReadOnlyDirectories=... for whitelisting files for a service. | |
465 | ||
466 | * sd-bus: | |
467 | - EBADSLT handling | |
468 | - GetAllProperties() on a non-existing object does not result in a failure currently | |
469 | - kdbus: process fd=-1 for incoming msgs | |
470 | - port to sd-resolve for connecting to TCP dbus servers | |
471 | - kdbus: maybe add controlling tty metadata fields | |
472 | - 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 | |
473 | - when kdbus does not take our message without memfds, try again with memfds | |
474 | - see if we can drop more message validation on the sending side | |
475 | - add API to clone sd_bus_message objects | |
476 | - make AddMatch calls on dbus1 transports async? | |
477 | - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too... | |
478 | - longer term: priority inheritance | |
479 | - dbus spec updates: | |
480 | - kdbus mapping | |
481 | - NameLost/NameAcquired obsolete | |
482 | - GVariant | |
483 | - path escaping | |
484 | - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now | |
485 | - test bloom filter generation indexes | |
486 | - bus-proxy: when passing messages from kdbus, make sure we properly | |
487 | handle the case where a large number of fds is appended that we | |
488 | cannot pass into sendmsg() of the AF_UNIX sokcet (which only accepts | |
489 | 253 messages) | |
490 | - kdbus: introduce a concept of "send-only" connections | |
491 | - kdbus: add counter for refused unicast messages that is passed out via the RECV ioctl. SImilar to the counter for dropped multicast messages we already have. | |
492 | ||
493 | * sd-event | |
494 | - allow multiple signal handlers per signal? | |
495 | - document chaining of signal handler for SIGCHLD and child handlers | |
496 | ||
497 | * in the final killing spree, detect processes from the root directory, and | |
498 | complain loudly if they have argv[0][0] == '@' set. | |
499 | https://bugzilla.redhat.com/show_bug.cgi?id=961044 | |
500 | ||
501 | * investigate endianness issues of UUID vs. GUID | |
502 | ||
503 | * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we | |
504 | should be able to safely try another attempt when the bus call LoadUnit() is invoked. | |
505 | ||
506 | * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login. | |
507 | ||
508 | * add a pam module that on password changes updates any LUKS slot where the password matches | |
509 | ||
510 | * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases... | |
511 | ||
512 | * cgtop: make cgtop useful in a container | |
513 | ||
514 | * test/: | |
515 | - add 'set -e' to scripts in test/ | |
516 | - make stuff in test/ work with separate output dir | |
517 | ||
518 | * seems that when we follow symlinks to units we prefer the symlink | |
519 | destination path over /etc and /usr. We should not do that. Instead | |
520 | /etc should always override /run+/usr and also any symlink | |
521 | destination. | |
522 | ||
523 | * when isolating, try to figure out a way how we implicitly can order | |
524 | all units we stop before the isolating unit... | |
525 | ||
526 | * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off}) | |
527 | ||
528 | * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify | |
529 | that the boot loader should be installed to the ESP. Define a way | |
530 | how an installer can figure out whether a BLS compliant boot loader | |
531 | is installed. | |
532 | ||
533 | * think about requeuing jobs when daemon-reload is issued? usecase: | |
534 | the initrd issues a reload after fstab from the host is accessible | |
535 | and we might want to requeue the mounts local-fs acquired through | |
536 | that automatically. | |
537 | ||
538 | * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep() | |
539 | ||
540 | * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8. | |
541 | ||
542 | * remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good | |
543 | ||
544 | * shutdown logging: store to EFI var, and store to USB stick? | |
545 | ||
546 | * write UI tool that pops up emergency messages from the journal as notification | |
547 | ||
548 | * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service | |
549 | ||
550 | * merge unit_kill_common() and unit_kill_context() | |
551 | ||
552 | * introduce ExecCondition= in services | |
553 | ||
554 | * EFI: | |
555 | - honor language efi variables for default language selection (if there are any?) | |
556 | - honor timezone efi variables for default timezone selection (if there are any?) | |
557 | - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables | |
558 | ||
559 | * maybe do not install getty@tty1.service symlink in /etc but in /usr? | |
560 | ||
561 | * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word | |
562 | ||
563 | * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units. | |
564 | ||
565 | * logind: | |
566 | - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around | |
567 | - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot | |
568 | - logind: wakelock/opportunistic suspend support | |
569 | - Add pretty name for seats in logind | |
570 | - logind: allow showing logout dialog from system? | |
571 | - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case | |
572 | - session scopes/user unit: add RequiresMountsFor for the home directory of the user | |
573 | - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly. | |
574 | - if pam_systemd is invoked by su from a process that is outside of a | |
575 | any session we should probably just become a NOP, since that's | |
576 | usually not a real user session but just some system code that just | |
577 | needs setuid(). | |
578 | - logind: make the Suspend()/Hibernate() bus calls wait for the for | |
579 | the job to be completed. before returning, so that clients can wait | |
580 | for "systemctl suspend" to finish to know when the suspending is | |
581 | complete. | |
582 | - logind: when the power button is pressed short, just popup a | |
583 | logout dialog. If it is pressed for 1s, do the usual | |
584 | shutdown. Inspiration are Macs here. | |
585 | - expose "Locked" property on logind sesison objects | |
586 | - given that logind now lets PID 1 do all nasty work, we can | |
587 | probably reduce the capability set it retains substantially. | |
588 | (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it) | |
589 | - expose orientation sensors and tablet mode through logind | |
590 | ||
591 | * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty. | |
592 | ||
593 | * service: watchdog logic: for testing purposes allow ping, but do not require pong | |
594 | ||
595 | * journal: | |
596 | - consider introducing implicit _TTY= + _PPID= + _EUID= + _EGID= + _FSUID= + _FSGID= fields | |
597 | - import and delete pstore filesystem content at startup | |
598 | - journald: also get thread ID from client, plus thread name | |
599 | - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups | |
600 | - add API to close/reopen/get fd for journal client fd in libsystemd-journal. | |
601 | - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively? | |
602 | - declare the local journal protocol stable in the wiki interface chart | |
603 | - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg | |
604 | - journald: when dropping msgs due to ratelimit make sure to write | |
605 | "dropped %u messages" not only when we are about to print the next | |
606 | message that works, but alraedy after a short tiemout | |
607 | - check if we can make journalctl by default use --follow mode inside of less if called without args? | |
608 | - maybe add API to send pairs of iovecs via sd_journal_send | |
609 | - journal: when writing journal auto-rotate if time jumps backwards | |
610 | - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access | |
611 | - journactl: support negative filtering, i.e. FOOBAR!="waldo", | |
612 | and !FOOBAR for events without FOOBAR. | |
613 | - journal: store timestamp of journal_file_set_offline() int he header, | |
614 | so it is possible to display when the file was last synced. | |
615 | - 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. | |
616 | - journal: find a way to allow dropping history early, based on priority, other rules | |
617 | - journal: When used on NFS, check payload hashes | |
618 | - journald: add kernel cmdline option to disable ratelimiting for debug purposes | |
619 | - refuse taking lower-case variable names in sd_journal_send() and friends. | |
620 | - journald: we currently rotate only after MaxUse+MaxFilesize has been reached. | |
621 | - journal: deal nicely with byte-by-byte copied files, especially regards header | |
622 | - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit | |
623 | - Replace utmp, wtmp, btmp, and lastlog completely with journal | |
624 | - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax? | |
625 | - when a kernel driver logs in a tight loop, we should ratelimit that too. | |
626 | - journald: optionally, log debug messages to /run but everything else to /var | |
627 | - journald: when we drop syslog messages because the syslog socket is | |
628 | full, make sure to write how many messages are lost as first thing | |
629 | to syslog when it works again. | |
630 | - journald: make sure ratelimit is actually really per-service with the new cgroup changes | |
631 | - change systemd-journal-flush into a service that stays around during | |
632 | boot, and causes the journal to be moved back to /run on shutdown, | |
633 | so that we do not keep /var busy. This needs to happen synchronously, | |
634 | hence doing this via signals is not going to work. | |
635 | - optionally support running journald from the command line for testing purposes in external projects | |
636 | - journald: allow per-priority and per-service retention times when rotating/vacuuming | |
637 | - journald: make use of uid-range.h to managed uid ranges to split | |
638 | journals in. | |
639 | - journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so... | |
640 | - improve journalctl performance by loading journal files | |
641 | lazily. Encode just enough information in the file name, so that we | |
642 | do not have to open it to know that it is not interesting for us, for | |
643 | the most common operations. | |
644 | ||
645 | * document: | |
646 | - document that deps in [Unit] sections ignore Alias= fields in | |
647 | [Install] units of other units, unless those units are disabled | |
648 | - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets | |
649 | - document the exit codes when services fail before they are exec()ed | |
650 | - document that service reload may be implemented as service reexec | |
651 | - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications | |
652 | - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr. | |
653 | - document systemd-journal-flush.service properly | |
654 | - documentation: recommend to connect the timer units of a service to the service via Also= in [Install] | |
655 | - man: document the very specific env the shutdown drop-in tools live in | |
656 | - man: add more examples to man pages | |
657 | - man: maybe sort directives in man pages, and take sections from --help and apply them to man too | |
658 | ||
659 | * systemctl: | |
660 | - systemctl list-jobs - show dependencies | |
661 | - add systemctl switch to dump transaction without executing it | |
662 | - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done | |
663 | - "systemctl disable" on a static unit prints no message and does | |
664 | nothing. "systemctl enable" does nothing, and gives a bad message | |
665 | about it. Should fix both to print nice actionable messages. | |
666 | - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service | |
667 | - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible | |
668 | - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards? | |
669 | - systemctl: "Journal has been rotated since unit was started." message is misleading | |
670 | - better error message if you run systemctl without systemd running | |
671 | - systemctl status output should should include list of triggering units and their status | |
672 | ||
673 | * unit install: | |
674 | - "systemctl mask" should find all names by which a unit is accessible | |
675 | (i.e. by scanning for symlinks to it) and link them all to /dev/null | |
676 | - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so) | |
677 | ||
678 | * timer units: | |
679 | - timer units should get the ability to trigger when: | |
680 | o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET) | |
681 | o DST changes | |
682 | - Support 2012-02~4 as syntax for specifying the fourth to last day of the month. | |
683 | - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1 | |
684 | - Modulate timer frequency based on battery state | |
685 | ||
686 | * add libsystemd-password or so to query passwords during boot using the password agent logic | |
687 | ||
688 | * 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(). | |
689 | ||
690 | * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed | |
691 | ||
692 | * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel | |
693 | ||
694 | * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without | |
695 | waiting for the timeout | |
696 | ||
697 | * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ... | |
698 | ||
699 | * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not | |
700 | ||
701 | * nspawn: | |
702 | - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK). | |
703 | ||
704 | * cryptsetup: | |
705 | - cryptsetup-generator: allow specification of passwords in crypttab itself | |
706 | - move cryptsetup key caching into kernel keyctl? | |
707 | https://bugs.freedesktop.org/show_bug.cgi?id=54982 | |
708 | - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator | |
709 | ||
710 | * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it | |
711 | https://bugs.freedesktop.org/show_bug.cgi?id=54712 | |
712 | ||
713 | * after deserializing sockets in socket.c we should reapply sockopts and things | |
714 | ||
715 | * make timer units go away after they elapsed | |
716 | ||
717 | * move PID 1 segfaults to /var/lib/systemd/coredump? | |
718 | ||
719 | * create /sbin/init symlinks from the build system | |
720 | ||
721 | * allow writing multiple conditions in unit files on one line | |
722 | ||
723 | * MountFlags=shared acts as MountFlags=slave right now. | |
724 | ||
725 | * drop PID 1 reloading, only do reexecing (difficult: Reload() | |
726 | currently is properly synchronous, Reexec() is weird, because we | |
727 | cannot delay the response properly until we are back, so instead of | |
728 | being properly synchronous we just keep open the fd and close it | |
729 | when done. That means clients do not get a successful method reply, | |
730 | but much rather a disconnect on success. | |
731 | ||
732 | * properly handle loop back mounts via fstab, especially regards to fsck/passno | |
733 | ||
734 | * initialize the hostname from the fs label of /, if /etc/hostname does not exist? | |
735 | ||
736 | * rename "userspace" to "core-os" | |
737 | ||
738 | * load-fragment: when loading a unit file via a chain of symlinks | |
739 | verify that it is not masked via any of the names traversed. | |
740 | ||
741 | * introduce Type=pid-file | |
742 | ||
743 | * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr | |
744 | ||
745 | * ExecOnFailure=/usr/bin/foo | |
746 | ||
747 | * udev: | |
748 | - move to LGPL | |
749 | - kill scsi_id | |
750 | - add trigger --subsystem-match=usb/usb_device device | |
751 | - reimport udev db after MOVE events for devices without dev_t | |
752 | ||
753 | * when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting | |
754 | ||
755 | * introduce mix of BindTo and Requisite | |
756 | ||
757 | * There's currently no way to cancel fsck (used to be possible via C-c or c on the console) | |
758 | ||
759 | * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/ | |
760 | ||
761 | * save coredump in Windows/Mozilla minidump format | |
762 | ||
763 | * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting) | |
764 | ||
765 | * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max | |
766 | ||
767 | * be able to specify a forced restart of service A where service B depends on, in case B | |
768 | needs to be auto-respawned? | |
769 | ||
770 | * when a bus name of a service disappears from the bus make sure to queue further activation requests | |
771 | ||
772 | * tmpfiles: | |
773 | - apply "x" on "D" too (see patch from William Douglas) | |
774 | - replace F with f+. | |
775 | - instead of ignoring unknown fields, reject them. | |
776 | ||
777 | * for services: do not set $HOME in services unless requested | |
778 | ||
779 | * hide PAM options in fragment parser when compile time disabled | |
780 | ||
781 | * when we automatically restart a service, ensure we restart its rdeps, too. | |
782 | ||
783 | * allow Type=simple with PIDFile= | |
784 | https://bugzilla.redhat.com/show_bug.cgi?id=723942 | |
785 | ||
786 | * move PAM code into its own binary | |
787 | ||
788 | * implement Register= switch in .socket units to enable registration | |
789 | in Avahi, RPC and other socket registration services. | |
790 | ||
791 | * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early | |
792 | ||
793 | * add ReloadSignal= for configuring a reload signal to use | |
794 | ||
795 | * verify that the AF_UNIX sockets of a service in the fs still exist | |
796 | when we start a service in order to avoid confusion when a user | |
797 | assumes starting a service is enough to make it accessible | |
798 | ||
799 | * Make it possible to set the keymap independently from the font on | |
800 | the kernel cmdline. Right now setting one resets also the other. | |
801 | ||
802 | * and a dbus call to generate target from current state | |
803 | ||
804 | * GC unreferenced jobs (such as .device jobs) | |
805 | ||
806 | * write blog stories about: | |
807 | - hwdb: what belongs into it, lsusb | |
808 | - enabling dbus services | |
809 | - status update | |
810 | - how to make changes to sysctl and sysfs attributes | |
811 | - remote access | |
812 | - how to pass throw-away units to systemd, or dynamically change properties of existing units | |
813 | - testing with Harald's awesome test kit | |
814 | - auto-restart | |
815 | - how to develop against journal browsing APIs | |
816 | - the journal HTTP iface | |
817 | - non-cgroup resource management | |
818 | - dynamic resource management with cgroups | |
819 | - refreshed, longer missions statement | |
820 | - calendar time events | |
821 | - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell | |
822 | - how to create your own target | |
823 | - instantiated apache, dovecot and so on | |
824 | - hooking a script into various stages of shutdown/rearly booot | |
825 | ||
826 | * allow port=0 in .socket units | |
827 | ||
828 | * recreate systemd's D-Bus private socket file on SIGUSR2 | |
829 | ||
830 | * Support --test based on current system state | |
831 | ||
832 | * investigate whether the gnome pty helper should be moved into systemd, to provide cgroup support. | |
833 | ||
834 | * maybe introduce ExecRestartPre= | |
835 | ||
836 | * dot output for --test showing the 'initial transaction' | |
837 | ||
838 | * fingerprint.target, wireless.target, gps.target, netdevice.target | |
839 | ||
840 | * systemd-python: | |
841 | - figure out a simple way to wait for journal events in a way that | |
842 | works with ^C | |
843 | - add documentation to systemd.daemon | |
844 | ||
845 | * bootchart: | |
846 | - plot per-process IO utilization | |
847 | - group processes based on service association (cgroups) | |
848 | - document initcall_debug | |
849 | - kernel cmdline "bootchart" option for simplicity? | |
850 | ||
851 | * udev-link-config: | |
852 | - Make sure ID_PATH is always exported and complete for | |
853 | network devices where possible, so we can safely rely | |
854 | on Path= matching | |
855 | - check MTUBytes parsing (expecting size_t but we are using unsigned) | |
856 | ||
857 | * sd-rtnl: | |
858 | - add support for more attribute types | |
859 | - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places | |
860 | ||
861 | * networkd: | |
862 | - add more keys to [Route] and [Address] sections | |
863 | - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config) | |
864 | - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline) | |
865 | - add reduced [Link] support to .network files | |
866 | - add Scope= parsing option for [Network] | |
867 | - properly handle routerless dhcp leases | |
868 | - add more attribute support for SIT tunnel | |
869 | - work with non-Ethernet devices | |
870 | - add support for more bond options | |
871 | ||
872 | * networkd-wait-online: | |
873 | - make operstates to wait for configurable? | |
874 | ||
875 | * dhcp: | |
876 | - figure out how much we can increase Maximum Message Size | |
877 | - support RFC4702 (pass FQDN) | |
878 | ||
879 | * dhcp6: | |
880 | - add functions to set previously stored IPv6 addresses on startup and get | |
881 | them at shutdown; store them in client->ia_na | |
882 | - write more test cases | |
883 | - implement reconfigure support, see 5.3., 15.11. and 22.20. | |
884 | - implement support for temporary adressess (IA_TA) | |
885 | - implement dhcpv6 authentication | |
886 | - investigate the usefulness of Confirm messages; i.e. are there any | |
887 | situations where the link changes without any loss in carrier detection | |
888 | or interface down | |
889 | - some servers don't do rapid commit without a filled in IA_NA, verify | |
890 | this behavior | |
891 | ||
892 | External: | |
893 | ||
894 | * dbus: | |
895 | - natively watch for dbus-*.service symlinks (PENDING) | |
896 | - teach dbus to activate all services it finds in /etc/systemd/services/org-*.service | |
897 | ||
898 | * fix alsa mixer restore to not print error when no config is stored | |
899 | ||
900 | * make cryptsetup lower --iter-time | |
901 | ||
902 | * patch kernel for xattr support in /dev, /proc/, /sys? | |
903 | ||
904 | * kernel: add device_type = "fb", "fbcon" to class "graphics" | |
905 | ||
906 | * drop accountsservice's StandardOutput=syslog and Type=dbus fields | |
907 | ||
908 | * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id | |
909 | ||
910 | * /usr/bin/service should actually show the new command line | |
911 | ||
912 | * 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= | |
913 | ||
914 | * fedora: F20: go timer units all the way, leave cron.daily for cron | |
915 | ||
916 | * neither pkexec nor sudo initialize environ[] from the PAM environment? | |
917 | ||
918 | * fedora: update policy to declare access mode and ownership of unit files to root:root 0644, and add an rpmlint check for it | |
919 | ||
920 | * register catalog database signature as file magic | |
921 | ||
922 | * zsh shell completion: | |
923 | - <command> <verb> -<TAB> should complete options, but currently does not | |
924 | - systemctl add-wants,add-requires | |
925 | ||
926 | ||
927 | Regularly: | |
928 | ||
929 | * look for close() vs. close_nointr() vs. close_nointr_nofail() | |
930 | ||
931 | * check for strerror(r) instead of strerror(-r) | |
932 | ||
933 | * Use PR_SET_PROCTITLE_AREA if it becomes available in the kernel | |
934 | ||
935 | * pahole | |
936 | ||
937 | * set_put(), hashmap_put() return values check. i.e. == 0 does not free()! | |
938 | ||
939 | * use secure_getenv() instead of getenv() where appropriate | |
940 | ||
941 | * link up selected blog stories from man pages and unit files Documentation= fields |
