3 | CHANGES WITH 232 in spe |
4 | ||
5 | * Journald's SplitMode=login setting has been deprecated. It has been | |
6 | removed from documentation, and it's use is discouraged. In a future | |
7 | release it will be completely removed, and made equivalent to current | |
8 | default of SplitMode=uid. | |

10 | CHANGES WITH 231: |
11 | ||
fcd30826 LP |
12 | * In service units the various ExecXYZ= settings have been extended |
13 | with an additional special character as first argument of the | |
43eb109a | 14 | assigned value: if the character '+' is used the specified command |
fcd30826 LP |
15 | line it will be run with full privileges, regardless of User=, |
16 | Group=, CapabilityBoundingSet= and similar options. The effect is | |
17 | similar to the existing PermissionsStartOnly= option, but allows | |
18 | configuration of this concept for each executed command line | |
19 | independently. | |
20 | ||
21 | * Services may now alter the service watchdog timeout at runtime by | |
22 | sending a WATCHDOG_USEC= message via sd_notify(). | |
23 | ||
24 | * MemoryLimit= and related unit settings now optionally take percentage | |
25 | specifications. The percentage is taken relative to the amount of | |
26 | physical memory in the system (or in case of containers, the assigned | |
27 | amount of memory). This allows scaling service resources neatly with | |
771de3f5 | 28 | the amount of RAM available on the system. Similarly, systemd-logind's |
fcd30826 LP |
29 | RuntimeDirectorySize= option now also optionally takes percentage |
30 | values. | |
31 | ||
32 | * In similar fashion TasksMax= takes percentage values now, too. The | |
33 | value is taken relative to the configured maximum number of processes | |
34 | on the system. The per-service task maximum has been changed to 15% | |
35 | using this functionality. (Effectively this is an increase of 512 → | |
36 | 4915 for service units, given the kernel's default pid_max setting.) | |
37 | ||
38 | * Calendar time specifications in .timer units now understand a ".." | |
39 | syntax for time ranges. Example: "4..7:10" may now be used for | |
40 | defining a timer that is triggered at 4:10am, 5:10am, 6:10am and | |
41 | 7:10am every day. | |
42 | ||
43 | * The InaccessableDirectories=, ReadOnlyDirectories= and | |
44 | ReadWriteDirectories= unit file settings have been renamed to | |
45 | InaccessablePaths=, ReadOnlyPaths= and ReadWritePaths= and may now be | |
46 | applied to all kinds of file nodes, and not just directories, with | |
47 | the exception of symlinks. Specifically these settings may now be | |
48 | used on block and character device nodes, UNIX sockets and FIFOS as | |
49 | well as regular files. The old names of these settings remain | |
50 | available for compatibility. | |
51 | ||
52 | * systemd will now log about all service processes it kills forcibly | |
53 | (using SIGKILL) because they remained after the clean shutdown phase | |
54 | of the service completed. This should help identifying services that | |
55 | shut down uncleanly. Moreover if KillUserProcesses= is enabled in | |
56 | systemd-logind's configuration a similar log message is generated for | |
57 | processes killed at the end of each session due to this setting. | |
58 | ||
59 | * systemd will now set the $JOURNAL_STREAM environment variable for all | |
60 | services whose stdout/stderr are connected to the Journal (which | |
61 | effectively means by default: all services). The variable contains | |
62 | the device and inode number of the file descriptor used for | |
63 | stdout/stderr. This may be used by invoked programs to detect whether | |
64 | their stdout/stderr is connected to the Journal, in which case they | |
65 | can switch over to direct Journal communication, thus being able to | |
66 | pass extended, structured metadata along with their log messages. As | |
67 | one example, this is now used by glib's logging primitives. | |
68 | ||
69 | * When using systemd's default tmp.mount unit for /tmp, the mount point | |
70 | will now be established with the "nosuid" and "nodev" options. This | |
71 | avoids privilege escalation attacks that put traps and exploits into | |
72 | /tmp. However, this might cause problems if you e. g. put container | |
5cd118ba MP |
73 | images or overlays into /tmp; if you need this, override tmp.mount's |
74 | "Options=" with a drop-in, or mount /tmp from /etc/fstab with your | |
75 | desired options. | |
76 | ||
fcd30826 LP |
77 | * systemd now supports the "memory" cgroup controller also on |
78 | cgroupsv2. | |
79 | ||
80 | * The systemd-cgtop tool now optionally takes a control group path as | |
81 | command line argument. If specified, the control group list shown is | |
82 | limited to subgroups of that group. | |
83 | ||
84 | * The SystemCallFilter= unit file setting gained support for | |
85 | pre-defined, named system call filter sets. For example | |
86 | SystemCallFilter=@clock is now an effective way to make all clock | |
771de3f5 | 87 | changing-related system calls unavailable to a service. A number of |
fcd30826 LP |
88 | similar pre-defined groups are defined. Writing system call filters |
89 | for system services is simplified substantially with this new | |
90 | concept. Accordingly, all of systemd's own, long-running services now | |
91 | enable system call filtering based on this, by default. | |
92 | ||
93 | * A new service setting MemoryDenyWriteExecute= has been added, taking | |
94 | a boolean value. If turned on, a service may no longer create memory | |
95 | mappings that are writable and executable at the same time. This | |
96 | enhances security for services where this is enabled as it becomes | |
97 | harder to dynamically write and then execute memory in exploited | |
98 | service processes. This option has been enabled for all of systemd's | |
99 | own long-running services. | |
100 | ||
101 | * A new RestrictRealtime= service setting has been added, taking a | |
102 | boolean argument. If set the service's processes may no longer | |
103 | acquire realtime scheduling. This improves security as realtime | |
104 | scheduling may otherwise be used to easily freeze the system. | |
105 | ||
106 | * systemd-nspawn gained a new switch --notify-ready= taking a boolean | |
107 | value. This may be used for requesting that the system manager inside | |
108 | of the container reports start-up completion to nspawn which then | |
109 | propagates this notification further to the service manager | |
110 | supervising nspawn itself. A related option NotifyReady= in .nspawn | |
111 | files has been added too. This functionality allows ordering of the | |
112 | start-up of multiple containers using the usual systemd ordering | |
113 | primitives. | |
114 | ||
115 | * machinectl gained a new command "stop" that is an alias for | |
116 | "terminate". | |
117 | ||
118 | * systemd-resolved gained support for contacting DNS servers on | |
119 | link-local IPv6 addresses. | |
120 | ||
121 | * If systemd-resolved receives the SIGUSR2 signal it will now flush all | |
122 | its caches. A method call for requesting the same operation has been | |
123 | added to the bus API too, and is made available via "systemd-resolve | |
124 | --flush-caches". | |
125 | ||
771de3f5 | 126 | * systemd-resolve gained a new --status switch. If passed a brief |
fcd30826 LP |
127 | summary of the used DNS configuration with per-interface information |
128 | is shown. | |
129 | ||
130 | * resolved.conf gained a new Cache= boolean option, defaulting to | |
131 | on. If turned off local DNS caching is disabled. This comes with a | |
132 | performance penalty in particular when DNSSEC is enabled. Note that | |
771de3f5 | 133 | resolved disables its internal caching implicitly anyway, when the |
fcd30826 LP |
134 | configured DNS server is on a host-local IP address such as ::1 or |
135 | 127.0.0.1, thus automatically avoiding double local caching. | |
136 | ||
137 | * systemd-resolved now listens on the local IP address 127.0.0.53:53 | |
138 | for DNS requests. This improves compatibility with local programs | |
139 | that do not use the libc NSS or systemd-resolved's bus APIs for name | |
140 | resolution. This minimal DNS service is only available to local | |
141 | programs and does not implement the full DNS protocol, but enough to | |
142 | cover local DNS clients. A new, static resolv.conf file, listing just | |
143 | this DNS server is now shipped in /usr/lib/systemd/resolv.conf. It is | |
144 | now recommended to make /etc/resolv.conf a symlink to this file in | |
145 | order to route all DNS lookups to systemd-resolved, regardless if | |
146 | done via NSS, the bus API or raw DNS packets. Note that this local | |
147 | DNS service is not as fully featured as the libc NSS or | |
148 | systemd-resolved's bus APIs. For example, as unicast DNS cannot be | |
149 | used to deliver link-local address information (as this implies | |
150 | sending a local interface index along), LLMNR/mDNS support via this | |
151 | interface is severely restricted. It is thus strongly recommended for | |
152 | all applications to use the libc NSS API or native systemd-resolved | |
153 | bus API instead. | |
154 | ||
155 | * systemd-networkd's bridge support learned a new setting | |
156 | VLANFiltering= for controlling VLAN filtering. Moreover a new section | |
157 | in .network files has been added for configuring VLAN bridging in | |
158 | more detail: VLAN=, EgressUntagged=, PVID= in [BridgeVLAN]. | |
159 | ||
160 | * systemd-networkd's IPv6 Router Advertisement code now makes use of | |
161 | the DNSSL and RDNSS options. This means IPv6 DNS configuration may | |
162 | now be acquired without relying on DHCPv6. Two new options | |
163 | UseDomains= and UseDNS= have been added to configure this behaviour. | |
164 | ||
165 | * systemd-networkd's IPv6AcceptRouterAdvertisements= option has been | |
166 | renamed IPv6AcceptRA=, without altering its behaviour. The old | |
167 | setting name remains available for compatibility reasons. | |
168 | ||
169 | * The systemd-networkd VTI/VTI6 tunneling support gained new options | |
170 | Key=, InputKey= and OutputKey=. | |
171 | ||
172 | * systemd-networkd gained support for VRF ("Virtual Routing Function") | |
173 | interface configuration. | |
174 | ||
175 | * "systemctl edit" may now be used to create new unit files by | |
176 | specifying the --force switch. | |
177 | ||
178 | * sd-event gained a new function sd_event_get_iteration() for | |
179 | requesting the current iteration counter of the event loop. It starts | |
180 | at zero and is increased by one with each event loop iteration. | |
181 | ||
43a569a1 ZJS |
182 | * A new rpm macro %systemd_ordering is provided by the macros.systemd |
183 | file. It can be used in lieu of %systemd_requires in packages which | |
184 | don't use any systemd functionality and are intended to be installed | |
185 | in minimal containers without systemd present. This macro provides | |
186 | ordering dependecies to ensure that if the package is installed in | |
187 | the same rpm transaction as systemd, systemd will be installed before | |
188 | the scriptlets for the package are executed, allowing unit presets | |
189 | to be handled. | |
190 | ||
191 | New macros %_systemdgeneratordir and %_systemdusergeneratordir have | |
192 | been added to simplify packaging of generators. | |
193 | ||
194 | * The os-release file gained VERSION_CODENAME field for the | |
195 | distribution nickname (e.g. VERSION_CODENAME=woody). | |
196 | ||
197 | * New udev property UDEV_DISABLE_PERSISTENT_STORAGE_RULES_FLAG=1 | |
198 | can be set to disable parsing of metadata and the creation | |
199 | of persistent symlinks for that device. | |
200 | ||
0f1da52b LP |
201 | * The v230 change to tag framebuffer devices (/dev/fb*) with "uaccess" |
202 | to make them available to logged-in users has been reverted. | |
203 | ||
204 | * Much of the common code of the various systemd components is now | |
205 | built into an internal shared library libsystemd-shared-231.so | |
206 | (incorporating the systemd version number in the name, to be updated | |
207 | with future releases) that the components link to. This should | |
208 | decrease systemd footprint both in memory during runtime and on | |
209 | disk. Note that the shared library is not for public use, and is | |
210 | neither API not ABI stable, but is likely to change with every new | |
1ecbf32f ZJS |
211 | released update. Packagers need to make sure that binaries |
212 | linking to libsystemd-shared.so are updated in step with the | |
213 | library. | |
43a569a1 | 214 | |
fcd30826 LP |
215 | * Configuration for "mkosi" is now part of the systemd |
216 | repository. mkosi is a tool to easily build legacy-free OS images, | |
217 | and is available on github: https://github.com/systemd/mkosi. If | |
218 | "mkosi" is invoked in the build tree a new raw OS image is generated | |
219 | incorporating the systemd sources currently being worked on and a | |
220 | clean, fresh distribution installation. The generated OS image may be | |
221 | booted up with "systemd-nspawn -b -i", qemu-kvm or on any physcial | |
222 | UEFI PC. This functionality is particularly useful to easily test | |
223 | local changes made to systemd in a pristine, defined environment. See | |
224 | HACKING for details. | |

46e40fab | 248 | CHANGES WITH 230: |
7f6e8043 | 249 | |
61ecb465 LP |
250 | * DNSSEC is now turned on by default in systemd-resolved (in |
251 | "allow-downgrade" mode), but may be turned off during compile time by | |
252 | passing "--with-default-dnssec=no" to "configure" (and of course, | |
253 | during runtime with DNSSEC= in resolved.conf). We recommend | |
254 | downstreams to leave this on at least during development cycles and | |
255 | report any issues with the DNSSEC logic upstream. We are very | |
256 | interested in collecting feedback about the DNSSEC validator and its | |
257 | limitations in the wild. Note however, that DNSSEC support is | |
258 | probably nothing downstreams should turn on in stable distros just | |
96d49011 | 259 | yet, as it might create incompatibilities with a few DNS servers and |
61ecb465 LP |
260 | networks. We tried hard to make sure we downgrade to non-DNSSEC mode |
261 | automatically whenever we detect such incompatible setups, but there | |
262 | might be systems we do not cover yet. Hence: please help us testing | |
263 | the DNSSEC code, leave this on where you can, report back, but then | |
264 | again don't consider turning this on in your stable, LTS or | |
e40a326c LP |
265 | production release just yet. (Note that you have to enable |
266 | nss-resolve in /etc/nsswitch.conf, to actually use systemd-resolved | |
267 | and its DNSSEC mode for host name resolution from local | |
268 | applications.) | |
61ecb465 | 269 | |
96515dbf | 270 | * systemd-resolve conveniently resolves DANE records with the --tlsa |
e40a326c | 271 | option and OPENPGPKEY records with the --openpgp option. It also |
e75690c3 | 272 | supports dumping raw DNS record data via the new --raw= switch. |
96515dbf | 273 | |
97e5530c ZJS |
274 | * systemd-logind will now by default terminate user processes that are |
275 | part of the user session scope unit (session-XX.scope) when the user | |
977f2bea | 276 | logs out. This behavior is controlled by the KillUserProcesses= |
e40a326c LP |
277 | setting in logind.conf, and the previous default of "no" is now |
278 | changed to "yes". This means that user sessions will be properly | |
279 | cleaned up after, but additional steps are necessary to allow | |
280 | intentionally long-running processes to survive logout. | |
97e5530c ZJS |
281 | |
282 | While the user is logged in at least once, user@.service is running, | |
283 | and any service that should survive the end of any individual login | |
284 | session can be started at a user service or scope using systemd-run. | |
e40a326c | 285 | systemd-run(1) man page has been extended with an example which shows |
8951eaec | 286 | how to run screen in a scope unit underneath user@.service. The same |
e40a326c | 287 | command works for tmux. |
97e5530c ZJS |
288 | |
289 | After the user logs out of all sessions, user@.service will be | |
290 | terminated too, by default, unless the user has "lingering" enabled. | |
291 | To effectively allow users to run long-term tasks even if they are | |
152199f2 ZJS |
292 | logged out, lingering must be enabled for them. See loginctl(1) for |
293 | details. The default polkit policy was modified to allow users to | |
294 | set lingering for themselves without authentication. | |
7f6e8043 | 295 | |
95365a57 | 296 | Previous defaults can be restored at compile time by the |
e40a326c | 297 | --without-kill-user-processes option to "configure". |
7f6e8043 | 298 | |
e75690c3 ZJS |
299 | * systemd-logind gained new configuration settings SessionsMax= and |
300 | InhibitorsMax=, both with a default of 8192. It will not register new | |
188d3082 | 301 | user sessions or inhibitors above this limit. |
e75690c3 ZJS |
302 | |
303 | * systemd-logind will now reload configuration on SIGHUP. | |
304 | ||
96515dbf | 305 | * The unified cgroup hierarchy added in Linux 4.5 is now supported. |
e40a326c | 306 | Use systemd.unified_cgroup_hierarchy=1 on the kernel command line to |
25b0e6cb LP |
307 | enable. Also, support for the "io" cgroup controller in the unified |
308 | hierarchy has been added, so that the "memory", "pids" and "io" are | |
309 | now the controllers that are supported on the unified hierarchy. | |
e40a326c | 310 | |
96515dbf ZJS |
311 | WARNING: it is not possible to use previous systemd versions with |
312 | systemd.unified_cgroup_hierarchy=1 and the new kernel. Therefore it | |
313 | is necessary to also update systemd in the initramfs if using the | |
e40a326c | 314 | unified hierarchy. An updated SELinux policy is also required. |
96515dbf | 315 | |
e40a326c LP |
316 | * LLDP support has been extended, and both passive (receive-only) and |
317 | active (sender) modes are supported. Passive mode ("routers-only") is | |
8951eaec ZJS |
318 | enabled by default in systemd-networkd. Active LLDP mode is enabled |
319 | by default for containers on the internal network. The "networkctl | |
e40a326c LP |
320 | lldp" command may be used to list information gathered. "networkctl |
321 | status" will also show basic LLDP information on connected peers now. | |
96515dbf | 322 | |
e40a326c LP |
323 | * The IAID and DUID unique identifier sent in DHCP requests may now be |
324 | configured for the system and each .network file managed by | |
e75690c3 ZJS |
325 | systemd-networkd using the DUIDType=, DUIDRawData=, IAID= options. |
326 | ||
327 | * systemd-networkd gained support for configuring proxy ARP support for | |
328 | each interface, via the ProxyArp= setting in .network files. It also | |
329 | gained support for configuring the multicast querier feature of | |
330 | bridge devices, via the new MulticastQuerier= setting in .netdev | |
331 | files. Similarly, snooping on the IGMP traffic can be controlled | |
332 | via the new setting MulticastSnooping=. | |
333 | ||
334 | A new setting PreferredLifetime= has been added for addresses | |
335 | configured in .network file to configure the lifetime intended for an | |
336 | address. | |
337 | ||
338 | The systemd-networkd DHCP server gained the option EmitRouter=, which | |
339 | defaults to yes, to configure whether the DHCP Option 3 (Router) | |
340 | should be emitted. | |
96515dbf | 341 | |
e40a326c | 342 | * The testing tool /usr/lib/systemd/systemd-activate is renamed to |
97e5530c ZJS |
343 | systemd-socket-activate and installed into /usr/bin. It is now fully |
344 | supported. | |
345 | ||
e40a326c LP |
346 | * systemd-journald now uses separate threads to flush changes to disk |
347 | when closing journal files, thus reducing impact of slow disk I/O on | |
348 | logging performance. | |
96515dbf | 349 | |
e75690c3 ZJS |
350 | * The sd-journal API gained two new calls |
351 | sd_journal_open_directory_fd() and sd_journal_open_files_fd() which | |
352 | can be used to open journal files using file descriptors instead of | |
353 | file or directory paths. sd_journal_open_container() has been | |
354 | deprecated, sd_journal_open_directory_fd() should be used instead | |
355 | with the flag SD_JOURNAL_OS_ROOT. | |
356 | ||
357 | * journalctl learned a new output mode "-o short-unix" that outputs log | |
358 | lines prefixed by their UNIX time (i.e. seconds since Jan 1st, 1970 | |
359 | UTC). It also gained support for a new --no-hostname setting to | |
360 | suppress the hostname column in the family of "short" output modes. | |
361 | ||
e40a326c LP |
362 | * systemd-ask-password now optionally skips printing of the password to |
363 | stdout with --no-output which can be useful in scripts. | |
96515dbf ZJS |
364 | |
365 | * Framebuffer devices (/dev/fb*) and 3D printers and scanners | |
366 | (devices tagged with ID_MAKER_TOOL) are now tagged with | |
367 | "uaccess" and are available to logged in users. | |
368 | ||
e75690c3 | 369 | * The DeviceAllow= unit setting now supports specifiers (with "%"). |
e40a326c LP |
370 | |
371 | * "systemctl show" gained a new --value switch, which allows print a | |
372 | only the contents of a specific unit property, without also printing | |
8951eaec ZJS |
373 | the property's name. Similar support was added to "show*" verbs |
374 | of loginctl and machinectl that output "key=value" lists. | |
e40a326c | 375 | |
e75690c3 ZJS |
376 | * A new unit type "generated" was added for files dynamically generated |
377 | by generator tools. Similarly, a new unit type "transient" is used | |
378 | for unit files created using the runtime API. "systemctl enable" will | |
379 | refuse to operate on such files. | |
380 | ||
e40a326c LP |
381 | * A new command "systemctl revert" has been added that may be used to |
382 | revert to the vendor version of a unit file, in case local changes | |
383 | have been made by adding drop-ins or overriding the unit file. | |
384 | ||
385 | * "machinectl clean" gained a new verb to automatically remove all or | |
386 | just hidden container images. | |
387 | ||
e40a326c LP |
388 | * systemd-tmpfiles gained support for a new line type "e" for emptying |
389 | directories, if they exist, without creating them if they don't. | |
390 | ||
e40a326c LP |
391 | * systemd-nspawn gained support for automatically patching the UID/GIDs |
392 | of the owners and the ACLs of all files and directories in a | |
393 | container tree to match the UID/GID user namespacing range selected | |
394 | for the container invocation. This mode is enabled via the new | |
395 | --private-user-chown switch. It also gained support for automatically | |
396 | choosing a free, previously unused UID/GID range when starting a | |
397 | container, via the new --private-users=pick setting (which implies | |
398 | --private-user-chown). Together, these options for the first time | |
399 | make user namespacing for nspawn containers fully automatic and thus | |
e81f2539 | 400 | deployable. The systemd-nspawn@.service template unit file has been |
e40a326c LP |
401 | changed to use this functionality by default. |
402 | ||
25b0e6cb LP |
403 | * systemd-nspawn gained a new --network-zone= switch, that allows |
404 | creating ad-hoc virtual Ethernet links between multiple containers, | |
405 | that only exist as long as at least one container referencing them is | |
406 | running. This allows easy connecting of multiple containers with a | |
407 | common link that implements an Ethernet broadcast domain. Each of | |
408 | these network "zones" may be named relatively freely by the user, and | |
409 | may be referenced by any number of containers, but each container may | |
410 | only reference one of these "zones". On the lower level, this is | |
411 | implemented by an automatically managed bridge network interface for | |
412 | each zone, that is created when the first container referencing its | |
413 | zone is created and removed when the last one referencing its zone | |
414 | terminates. | |
415 | ||
e40a326c | 416 | * The default start timeout may now be configured on the kernel command |
8951eaec ZJS |
417 | line via systemd.default_timeout_start_sec=. It was already |
418 | configurable via the DefaultTimeoutStartSec= option in | |
419 | /etc/systemd/system.conf. | |
e40a326c | 420 | |
030bd839 | 421 | * Socket units gained a new TriggerLimitIntervalSec= and |
e40a326c LP |
422 | TriggerLimitBurst= setting to configure a limit on the activation |
423 | rate of the socket unit. | |
424 | ||
425 | * The LimitNICE= setting now optionally takes normal UNIX nice values | |
426 | in addition to the raw integer limit value. If the specified | |
427 | parameter is prefixed with "+" or "-" and is in the range -20..19 the | |
428 | value is understood as UNIX nice value. If not prefixed like this it | |
429 | is understood as raw RLIMIT_NICE limit. | |
430 | ||
999a43f8 LP |
431 | * Note that the effect of the PrivateDevices= unit file setting changed |
432 | slightly with this release: the per-device /dev file system will be | |
433 | mounted read-only from this version on, and will have "noexec" | |
188d3082 | 434 | set. This (minor) change of behavior might cause some (exceptional) |
999a43f8 LP |
435 | legacy software to break, when PrivateDevices=yes is set for its |
436 | service. Please leave PrivateDevices= off if you run into problems | |
437 | with this. | |
438 | ||
e75690c3 ZJS |
439 | * systemd-bootchart has been split out to a separate repository: |
440 | https://github.com/systemd/systemd-bootchart | |
441 | ||
442 | * systemd-bus-proxyd has been removed, as kdbus is unlikely to still be | |
443 | merged into the kernel in its current form. | |
444 | ||
445 | * The compatibility libraries libsystemd-daemon.so, | |
446 | libsystemd-journal.so, libsystemd-id128.so, and libsystemd-login.so | |
447 | which have been deprecated since systemd-209 have been removed along | |
448 | with the corresponding pkg-config files. All symbols provided by | |
449 | those libraries are provided by libsystemd.so. | |
450 | ||
451 | * The Capabilities= unit file setting has been removed (it is ignored | |
452 | for backwards compatibility). AmbientCapabilities= and | |
453 | CapabilityBoundingSet= should be used instead. | |
454 | ||
4f9020fa DR |
455 | * A new special target has been added, initrd-root-device.target, |
456 | which creates a synchronization point for dependencies of the root | |
457 | device in early userspace. Initramfs builders must ensure that this | |
458 | target is now included in early userspace. | |

489 | CHANGES WITH 229: |
490 | ||
d5f8b295 LP |
491 | * The systemd-resolved DNS resolver service has gained a substantial |
492 | set of new features, most prominently it may now act as a DNSSEC | |
493 | validating stub resolver. DNSSEC mode is currently turned off by | |
ed5f8840 ZJS |
494 | default, but is expected to be turned on by default in one of the |
495 | next releases. For now, we invite everybody to test the DNSSEC logic | |
496 | by setting DNSSEC=allow-downgrade in /etc/systemd/resolved.conf. The | |
497 | service also gained a full set of D-Bus interfaces, including calls | |
498 | to configure DNS and DNSSEC settings per link (for use by external | |
499 | network management software). systemd-resolved and systemd-networkd | |
500 | now distinguish between "search" and "routing" domains. The former | |
501 | are used to qualify single-label names, the latter are used purely | |
502 | for routing lookups within certain domains to specific links. | |
503 | resolved now also synthesizes RRs for all entries from /etc/hosts. | |
d5f8b295 LP |
504 | |
505 | * The systemd-resolve tool (which is a client utility for | |
ed5f8840 ZJS |
506 | systemd-resolved) has been improved considerably and is now fully |
507 | supported and documented. Hence it has moved from /usr/lib/systemd to | |
508 | /usr/bin. | |
d5f8b295 LP |
509 | |
510 | * /dev/disk/by-path/ symlink support has been (re-)added for virtio | |
511 | devices. | |
512 | ||
a7c723c0 LP |
513 | * The coredump collection logic has been reworked: when a coredump is |
514 | collected it is now written to disk, compressed and processed | |
515 | (including stacktrace extraction) from a new instantiated service | |
516 | systemd-coredump@.service, instead of directly from the | |
517 | /proc/sys/kernel/core_pattern hook we provide. This is beneficial as | |
518 | processing large coredumps can take up a substantial amount of | |
519 | resources and time, and this previously happened entirely outside of | |
520 | systemd's service supervision. With the new logic the core_pattern | |
521 | hook only does minimal metadata collection before passing off control | |
522 | to the new instantiated service, which is configured with a time | |
523 | limit, a nice level and other settings to minimize negative impact on | |
524 | the rest of the system. Also note that the new logic will honour the | |
525 | RLIMIT_CORE setting of the crashed process, which now allows users | |
526 | and processes to turn off coredumping for their processes by setting | |
527 | this limit. | |
528 | ||
529 | * The RLIMIT_CORE resource limit now defaults to "unlimited" for PID 1 | |
530 | and all forked processes by default. Previously, PID 1 would leave | |
531 | the setting at "0" for all processes, as set by the kernel. Note that | |
532 | the resource limit traditionally has no effect on the generated | |
533 | coredumps on the system if the /proc/sys/kernel/core_pattern hook | |
534 | logic is used. Since the limit is now honoured (see above) its | |
535 | default has been changed so that the coredumping logic is enabled by | |
536 | default for all processes, while allowing specific opt-out. | |
537 | ||
538 | * When the stacktrace is extracted from processes of system users, this | |
539 | is now done as "systemd-coredump" user, in order to sandbox this | |
540 | potentially security sensitive parsing operation. (Note that when | |
541 | processing coredumps of normal users this is done under the user ID | |
542 | of process that crashed, as before.) Packagers should take notice | |
543 | that it is now necessary to create the "systemd-coredump" system user | |
544 | and group at package installation time. | |
545 | ||
d5f8b295 LP |
546 | * The systemd-activate socket activation testing tool gained support |
547 | for SOCK_DGRAM and SOCK_SEQPACKET sockets using the new --datagram | |
548 | and --seqpacket switches. It also has been extended to support both | |
549 | new-style and inetd-style file descriptor passing. Use the new | |
550 | --inetd switch to request inetd-style file descriptor passing. | |
551 | ||
8968aea0 MP |
552 | * Most systemd tools now honor a new $SYSTEMD_COLORS environment |
553 | variable, which takes a boolean value. If set to false, ANSI color | |
d5f8b295 LP |
554 | output is disabled in the tools even when run on a terminal that |
555 | supports it. | |
556 | ||
557 | * The VXLAN support in networkd now supports two new settings | |
558 | DestinationPort= and PortRange=. | |
559 | ||
560 | * A new systemd.machine_id= kernel command line switch has been added, | |
561 | that may be used to set the machine ID in /etc/machine-id if it is | |
562 | not initialized yet. This command line option has no effect if the | |
563 | file is already initialized. | |
564 | ||
565 | * systemd-nspawn gained a new --as-pid2 switch that invokes any | |
566 | specified command line as PID 2 rather than PID 1 in the | |
ed5f8840 ZJS |
567 | container. In this mode PID 1 is a minimal stub init process that |
568 | implements the special POSIX and Linux semantics of PID 1 regarding | |
569 | signal and child process management. Note that this stub init process | |
570 | is implemented in nspawn itself and requires no support from the | |
571 | container image. This new logic is useful to support running | |
572 | arbitrary commands in the container, as normal processes are | |
d5f8b295 LP |
573 | generally not prepared to run as PID 1. |
574 | ||
575 | * systemd-nspawn gained a new --chdir= switch for setting the current | |
576 | working directory for the process started in the container. | |
577 | ||
ed5f8840 ZJS |
578 | * "journalctl /dev/sda" will now output all kernel log messages for |
579 | specified device from the current boot, in addition to all devices | |
580 | that are parents of it. This should make log output about devices | |
581 | pretty useful, as long as kernel drivers attach enough metadata to | |
582 | the log messages. (The usual SATA drivers do.) | |
d5f8b295 LP |
583 | |
584 | * The sd-journal API gained two new calls | |
585 | sd_journal_has_runtime_files() and sd_journal_has_persistent_files() | |
586 | that report whether log data from /run or /var has been found. | |
587 | ||
588 | * journalctl gained a new switch "--fields" that prints all journal | |
589 | record field names currently in use in the journal. This is backed | |
590 | by two new sd-journal API calls sd_journal_enumerate_fields() and | |
591 | sd_journal_restart_fields(). | |
592 | ||
593 | * Most configurable timeouts in systemd now expect an argument of | |
8968aea0 MP |
594 | "infinity" to turn them off, instead of "0" as before. The semantics |
595 | from now on is that a timeout of "0" means "now", and "infinity" | |
596 | means "never". To maintain backwards compatibility, "0" continues to | |
597 | turn off previously existing timeout settings. | |
d5f8b295 LP |
598 | |
599 | * "systemctl reload-or-try-restart" has been renamed to "systemctl | |
8968aea0 MP |
600 | try-reload-or-restart" to clarify what it actually does: the "try" |
601 | logic applies to both reloading and restarting, not just restarting. | |
602 | The old name continues to be accepted for compatibility. | |
603 | ||
604 | * On boot-up, when PID 1 detects that the system clock is behind the | |
605 | release date of the systemd version in use, the clock is now set | |
606 | to the latter. Previously, this was already done in timesyncd, in order | |
d5f8b295 LP |
607 | to avoid running with clocks set to the various clock epochs such as |
608 | 1902, 1938 or 1970. With this change the logic is now done in PID 1 | |
609 | in addition to timesyncd during early boot-up, so that it is enforced | |
610 | before the first process is spawned by systemd. Note that the logic | |
611 | in timesyncd remains, as it is more comprehensive and ensures | |
ed5f8840 | 612 | clock monotonicity by maintaining a persistent timestamp file in |
d5f8b295 LP |
613 | /var. Since /var is generally not available in earliest boot or the |
614 | initrd, this part of the logic remains in timesyncd, and is not done | |
615 | by PID 1. | |
616 | ||
50f48ad3 DM |
617 | * Support for tweaking details in net_cls.class_id through the |
618 | NetClass= configuration directive has been removed, as the kernel | |
619 | people have decided to deprecate that controller in cgroup v2. | |
620 | Userspace tools such as nftables are moving over to setting rules | |
621 | that are specific to the full cgroup path of a task, which obsoletes | |
622 | these controllers anyway. The NetClass= directive is kept around for | |
623 | legacy compatibility reasons. For a more in-depth description of the | |
624 | kernel change, please refer to the respective upstream commit: | |
625 | ||
626 | https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bd1060a1d671 | |
627 | ||
d5f8b295 | 628 | * A new service setting RuntimeMaxSec= has been added that may be used |
8968aea0 | 629 | to specify a maximum runtime for a service. If the timeout is hit, the |
d5f8b295 LP |
630 | service is terminated and put into a failure state. |
631 | ||
8968aea0 MP |
632 | * A new service setting AmbientCapabilities= has been added. It allows |
633 | configuration of additional Linux process capabilities that are | |
634 | passed to the activated processes. This is only available on very | |
d5f8b295 LP |
635 | recent kernels. |
636 | ||
637 | * The process resource limit settings in service units may now be used | |
638 | to configure hard and soft limits individually. | |
639 | ||
8968aea0 | 640 | * The various libsystemd APIs such as sd-bus or sd-event now publicly |
ed5f8840 ZJS |
641 | expose support for gcc's __attribute__((cleanup())) C extension. |
642 | Specifically, for many object destructor functions alternative | |
643 | versions have been added that have names suffixed with "p" and take a | |
644 | pointer to a pointer to the object to destroy, instead of just a | |
645 | pointer to the object itself. This is useful because these destructor | |
646 | functions may be used directly as parameters to the cleanup | |
647 | construct. Internally, systemd has been a heavy user of this GCC | |
648 | extension for a long time, and with this change similar support is | |
649 | now available to consumers of the library outside of systemd. Note | |
8968aea0 | 650 | that by using this extension in your sources compatibility with old |
ed5f8840 ZJS |
651 | and strictly ANSI compatible C compilers is lost. However, all gcc or |
652 | LLVM versions of recent years support this extension. | |
d5f8b295 LP |
653 | |
654 | * Timer units gained support for a new setting RandomizedDelaySec= that | |
8968aea0 MP |
655 | allows configuring some additional randomized delay to the configured |
656 | time. This is useful to spread out timer events to avoid load peaks in | |
657 | clusters or larger setups. | |
d5f8b295 LP |
658 | |
659 | * Calendar time specifications now support sub-second accuracy. | |
660 | ||
661 | * Socket units now support listening on SCTP and UDP-lite protocol | |
662 | sockets. | |
663 | ||
664 | * The sd-event API now comes with a full set of man pages. | |
665 | ||
666 | * Older versions of systemd contained experimental support for | |
667 | compressing journal files and coredumps with the LZ4 compressor that | |
668 | was not compatible with the lz4 binary (due to API limitations of the | |
669 | lz4 library). This support has been removed; only support for files | |
670 | compatible with the lz4 binary remains. This LZ4 logic is now | |
671 | officially supported and no longer considered experimental. | |
672 | ||
673 | * The dkr image import logic has been removed again from importd. dkr's | |
674 | micro-services focus doesn't fit into the machine image focus of | |
675 | importd, and quickly got out of date with the upstream dkr API. | |
676 | ||
677 | * Creation of the /run/lock/lockdev/ directory was dropped from | |
678 | tmpfiles.d/legacy.conf. Better locking mechanisms like flock() have | |
61f32bff MP |
679 | been available for many years. If you still need this, you need to |
680 | create your own tmpfiles.d config file with: | |
d5f8b295 LP |
681 | |
682 | d /run/lock/lockdev 0775 root lock - | |

706 | CHANGES WITH 228: |
707 | ||
a11c7ea5 LP |
708 | * A number of properties previously only settable in unit |
709 | files are now also available as properties to set when | |
710 | creating transient units programmatically via the bus, as it | |
711 | is exposed with systemd-run's --property= | |
712 | setting. Specifically, these are: SyslogIdentifier=, | |
713 | SyslogLevelPrefix=, TimerSlackNSec=, OOMScoreAdjust=, | |
714 | EnvironmentFile=, ReadWriteDirectories=, | |
715 | ReadOnlyDirectories=, InaccessibleDirectories=, | |
716 | ProtectSystem=, ProtectHome=, RuntimeDirectory=. | |
717 | ||
28c85daf LP |
718 | * When creating transient services via the bus API it is now |
719 | possible to pass in a set of file descriptors to use as | |
720 | STDIN/STDOUT/STDERR for the invoked process. | |
a11c7ea5 | 721 | |
f1f8a5a5 LP |
722 | * Slice units may now be created transiently via the bus APIs, |
723 | similar to the way service and scope units may already be | |
724 | created transiently. | |
725 | ||
a11c7ea5 LP |
726 | * Wherever systemd expects a calendar timestamp specification |
727 | (like in journalctl's --since= and --until= switches) UTC | |
728 | timestamps are now supported. Timestamps suffixed with "UTC" | |
729 | are now considered to be in Universal Time Coordinated | |
730 | instead of the local timezone. Also, timestamps may now | |
815bb5bd | 731 | optionally be specified with sub-second accuracy. Both of |
a11c7ea5 LP |
732 | these additions also apply to recurring calendar event |
733 | specification, such as OnCalendar= in timer units. | |
734 | ||
28c85daf LP |
735 | * journalctl gained a new "--sync" switch that asks the |
736 | journal daemon to write all so far unwritten log messages to | |
737 | disk and sync the files, before returning. | |
738 | ||
a11c7ea5 LP |
739 | * systemd-tmpfiles learned two new line types "q" and "Q" that |
740 | operate like "v", but also set up a basic btrfs quota | |
741 | hierarchy when used on a btrfs file system with quota | |
742 | enabled. | |
743 | ||
f1f8a5a5 LP |
744 | * tmpfiles' "v", "q" and "Q" will now create a plain directory |
745 | instead of a subvolume (even on a btrfs file system) if the | |
746 | root directory is a plain directory, and not a | |
747 | subvolume. This should simplify things with certain chroot() | |
748 | environments which are not aware of the concept of btrfs | |
749 | subvolumes. | |
750 | ||
a11c7ea5 LP |
751 | * systemd-detect-virt gained a new --chroot switch to detect |
752 | whether execution takes place in a chroot() environment. | |
753 | ||
28c85daf | 754 | * CPUAffinity= now takes CPU index ranges in addition to |
a11c7ea5 LP |
755 | individual indexes. |
756 | ||
28c85daf LP |
757 | * The various memory-related resource limit settings (such as |
758 | LimitAS=) now understand the usual K, M, G, ... suffixes to | |
759 | the base of 1024 (IEC). Similar, the time-related resource | |
760 | limit settings understand the usual min, h, day, ... | |
761 | suffixes now. | |
762 | ||
f1f8a5a5 LP |
763 | * There's a new system.conf setting DefaultTasksMax= to |
764 | control the default TasksMax= setting for services and | |
765 | scopes running on the system. (TasksMax= is the primary | |
766 | setting that exposes the "pids" cgroup controller on systemd | |
767 | and was introduced in the previous systemd release.) The | |
768 | setting now defaults to 512, which means services that are | |
769 | not explicitly configured otherwise will only be able to | |
770 | create 512 processes or threads at maximum, from this | |
771 | version on. Note that this means that thread- or | |
772 | process-heavy services might need to be reconfigured to set | |
773 | TasksMax= to a higher value. It is sufficient to set | |
774 | TasksMax= in these specific unit files to a higher value, or | |
775 | even "infinity". Similar, there's now a logind.conf setting | |
776 | UserTasksMax= that defaults to 4096 and limits the total | |
777 | number of processes or tasks each user may own | |
778 | concurrently. nspawn containers also have the TasksMax= | |
779 | value set by default now, to 8192. Note that all of this | |
780 | only has an effect if the "pids" cgroup controller is | |
781 | enabled in the kernel. The general benefit of these changes | |
782 | should be a more robust and safer system, that provides a | |
783 | certain amount of per-service fork() bomb protection. | |
784 | ||
28c85daf LP |
785 | * systemd-nspawn gained the new --network-veth-extra= switch |
786 | to define additional and arbitrarily-named virtual Ethernet | |
787 | links between the host and the container. | |
788 | ||
789 | * A new service execution setting PassEnvironment= has been | |
790 | added that allows importing select environment variables | |
791 | from PID1's environment block into the environment block of | |
792 | the service. | |
793 | ||
ddb4b0d3 | 794 | * Timer units gained support for a new RemainAfterElapse= |
595bfe7d | 795 | setting which takes a boolean argument. It defaults to on, |
ddb4b0d3 LP |
796 | exposing behaviour unchanged to previous releases. If set to |
797 | off, timer units are unloaded after they elapsed if they | |
798 | cannot elapse again. This is particularly useful for | |
799 | transient timer units, which shall not stay around longer | |
800 | than until they first elapse. | |
801 | ||
a11c7ea5 | 802 | * systemd will now bump the net.unix.max_dgram_qlen to 512 by |
28c85daf LP |
803 | default now (the kernel default is 16). This is beneficial |
804 | for avoiding blocking on AF_UNIX/SOCK_DGRAM sockets since it | |
a11c7ea5 LP |
805 | allows substantially larger numbers of queued |
806 | datagrams. This should increase the capability of systemd to | |
807 | parallelize boot-up, as logging and sd_notify() are unlikely | |
808 | to stall execution anymore. If you need to change the value | |
809 | from the new defaults, use the usual sysctl.d/ snippets. | |
810 | ||
28c85daf LP |
811 | * The compression framing format used by the journal or |
812 | coredump processing has changed to be in line with what the | |
813 | official LZ4 tools generate. LZ4 compression support in | |
814 | systemd was considered unsupported previously, as the format | |
815 | was not compatible with the normal tools. With this release | |
816 | this has changed now, and it is hence safe for downstream | |
817 | distributions to turn it on. While not compressing as well | |
815bb5bd | 818 | as the XZ, LZ4 is substantially faster, which makes |
28c85daf LP |
819 | it a good default choice for the compression logic in the |
820 | journal and in coredump handling. | |
a11c7ea5 | 821 | |
28c85daf LP |
822 | * Any reference to /etc/mtab has been dropped from |
823 | systemd. The file has been obsolete since a while, but | |
824 | systemd refused to work on systems where it was incorrectly | |
815bb5bd | 825 | set up (it should be a symlink or non-existent). Please make |
28c85daf LP |
826 | sure to update to util-linux 2.27.1 or newer in conjunction |
827 | with this systemd release, which also drops any reference to | |
828 | /etc/mtab. If you maintain a distribution make sure that no | |
829 | software you package still references it, as this is a | |
830 | likely source of bugs. There's also a glibc bug pending, | |
831 | asking for removal of any reference to this obsolete file: | |
832 | ||
833 | https://sourceware.org/bugzilla/show_bug.cgi?id=19108 | |
a11c7ea5 | 834 | |
d5bd92bb LP |
835 | Note that only util-linux versions built with |
836 | --enable-libmount-force-mountinfo are supported. | |
837 | ||
a11c7ea5 LP |
838 | * Support for the ".snapshot" unit type has been removed. This |
839 | feature turned out to be little useful and little used, and | |
840 | has now been removed from the core and from systemctl. | |
841 | ||
b9e2f7eb LP |
842 | * The dependency types RequiresOverridable= and |
843 | RequisiteOverridable= have been removed from systemd. They | |
844 | have been used only very sparingly to our knowledge and | |
845 | other options that provide a similar effect (such as | |
846 | systemctl --mode=ignore-dependencies) are much more useful | |
847 | and commonly used. Moreover, they were only half-way | |
848 | implemented as the option to control behaviour regarding | |
849 | these dependencies was never added to systemctl. By removing | |
850 | these dependency types the execution engine becomes a bit | |
851 | simpler. Unit files that use these dependencies should be | |
852 | changed to use the non-Overridable dependency types | |
853 | instead. In fact, when parsing unit files with these | |
854 | options, that's what systemd will automatically convert them | |
855 | too, but it will also warn, asking users to fix the unit | |
856 | files accordingly. Removal of these dependency types should | |
857 | only affect a negligible number of unit files in the wild. | |
858 | ||
859 | * Behaviour of networkd's IPForward= option changed | |
860 | (again). It will no longer maintain a per-interface setting, | |
861 | but propagate one way from interfaces where this is enabled | |
862 | to the global kernel setting. The global setting will be | |
863 | enabled when requested by a network that is set up, but | |
864 | never be disabled again. This change was made to make sure | |
865 | IPv4 and IPv6 behaviour regarding packet forwarding is | |
866 | similar (as the Linux IPv6 stack does not support | |
867 | per-interface control of this setting) and to minimize | |
868 | surprises. | |
869 | ||
28c85daf LP |
870 | * In unit files the behaviour of %u, %U, %h, %s has |
871 | changed. These specifiers will now unconditionally resolve | |
872 | to the various user database fields of the user that the | |
873 | systemd instance is running as, instead of the user | |
874 | configured in the specific unit via User=. Note that this | |
875 | effectively doesn't change much, as resolving of these | |
876 | specifiers was already turned off in the --system instance | |
877 | of systemd, as we cannot do NSS lookups from PID 1. In the | |
878 | --user instance of systemd these specifiers where correctly | |
879 | resolved, but hardly made any sense, since the user instance | |
880 | lacks privileges to do user switches anyway, and User= is | |
881 | hence useless. Morever, even in the --user instance of | |
882 | systemd behaviour was awkward as it would only take settings | |
883 | from User= assignment placed before the specifier into | |
884 | account. In order to unify and simplify the logic around | |
885 | this the specifiers will now always resolve to the | |
886 | credentials of the user invoking the manager (which in case | |
887 | of PID 1 is the root user). | |

c97e586d DM |
907 | CHANGES WITH 227: |
908 | ||
909 | * systemd now depends on util-linux v2.27. More specifically, | |
910 | the newly added mount monitor feature in libmount now | |
911 | replaces systemd's former own implementation. | |
912 | ||
913 | * libmount mandates /etc/mtab not to be regular file, and | |
914 | systemd now enforces this condition at early boot. | |
915 | /etc/mtab has been deprecated and warned about for a very | |
916 | long time, so systems running systemd should already have | |
917 | stopped having this file around as anything else than a | |
918 | symlink to /proc/self/mounts. | |
919 | ||
d046fb93 LP |
920 | * Support for the "pids" cgroup controller has been added. It |
921 | allows accounting the number of tasks in a cgroup and | |
c97e586d DM |
922 | enforcing limits on it. This adds two new setting |
923 | TasksAccounting= and TasksMax= to each unit, as well as a | |
6fd5517b | 924 | global option DefaultTasksAccounting=. |
c97e586d DM |
925 | |
926 | * Support for the "net_cls" cgroup controller has been added. | |
fe08a30b LP |
927 | It allows assigning a net class ID to each task in the |
928 | cgroup, which can then be used in firewall rules and traffic | |
929 | shaping configurations. Note that the kernel netfilter net | |
930 | class code does not currently work reliably for ingress | |
931 | packets on unestablished sockets. | |
c97e586d DM |
932 | |
933 | This adds a new config directive called NetClass= to CGroup | |
6fd5517b | 934 | enabled units. Allowed values are positive numbers for fixed |
c97e586d DM |
935 | assignments and "auto" for picking a free value |
936 | automatically. | |
937 | ||
21d86c61 DM |
938 | * 'systemctl is-system-running' now returns 'offline' if the |
939 | system is not booted with systemd. This command can now be | |
940 | used as a substitute for 'systemd-notify --booted'. | |
941 | ||
942 | * Watchdog timeouts have been increased to 3 minutes for all | |
943 | in-tree service files. Apparently, disk IO issues are more | |
944 | frequent than we hoped, and user reported >1 minute waiting | |
945 | for disk IO. | |
946 | ||
947 | * 'machine-id-commit' functionality has been merged into | |
948 | 'machine-id-setup --commit'. The separate binary has been | |
949 | removed. | |
950 | ||
d046fb93 LP |
951 | * The WorkingDirectory= directive in unit files may now be set |
952 | to the special value '~'. In this case, the working | |
953 | directory is set to the home directory of the user | |
954 | configured in User=. | |
21d86c61 | 955 | |
fe08a30b LP |
956 | * "machinectl shell" will now open the shell in the home |
957 | directory of the selected user by default. | |
958 | ||
21d86c61 | 959 | * The CrashChVT= configuration file setting is renamed to |
d046fb93 LP |
960 | CrashChangeVT=, following our usual logic of not |
961 | abbreviating unnecessarily. The old directive is still | |
962 | supported for compat reasons. Also, this directive now takes | |
963 | an integer value between 1 and 63, or a boolean value. The | |
964 | formerly supported '-1' value for disabling stays around for | |
965 | compat reasons. | |
21d86c61 | 966 | |
fe08a30b | 967 | * The PrivateTmp=, PrivateDevices=, PrivateNetwork=, |
8b5f9d15 | 968 | NoNewPrivileges=, TTYPath=, WorkingDirectory= and |
fe08a30b LP |
969 | RootDirectory= properties can now be set for transient |
970 | units. | |
971 | ||
972 | * The systemd-analyze tool gained a new "set-log-target" verb | |
973 | to change the logging target the system manager logs to | |
974 | dynamically during runtime. This is similar to how | |
975 | "systemd-analyze set-log-level" already changes the log | |
976 | level. | |
977 | ||
978 | * In nspawn /sys is now mounted as tmpfs, with only a selected | |
979 | set of subdirectories mounted in from the real sysfs. This | |
980 | enhances security slightly, and is useful for ensuring user | |
981 | namespaces work correctly. | |
982 | ||
983 | * Support for USB FunctionFS activation has been added. This | |
984 | allows implementation of USB gadget services that are | |
985 | activated as soon as they are requested, so that they don't | |
595bfe7d | 986 | have to run continuously, similar to classic socket |
fe08a30b LP |
987 | activation. |
988 | ||
989 | * The "systemctl exit" command now optionally takes an | |
990 | additional parameter that sets the exit code to return from | |
991 | the systemd manager when exiting. This is only relevant when | |
992 | running the systemd user instance, or when running the | |
993 | system instance in a container. | |
994 | ||
995 | * sd-bus gained the new API calls sd_bus_path_encode_many() | |
996 | and sd_bus_path_decode_many() that allow easy encoding and | |
997 | decoding of multiple identifier strings inside a D-Bus | |
998 | object path. Another new call sd_bus_default_flush_close() | |
999 | has been added to flush and close per-thread default | |
1000 | connections. | |
1001 | ||
1002 | * systemd-cgtop gained support for a -M/--machine= switch to | |
1003 | show the control groups within a certain container only. | |
1004 | ||
1005 | * "systemctl kill" gained support for an optional --fail | |
1006 | switch. If specified the requested operation will fail of no | |
1007 | processes have been killed, because the unit had no | |
1008 | processes attached, or similar. | |
1009 | ||
bdba9227 DM |
1010 | * A new systemd.crash_reboot=1 kernel command line option has |
1011 | been added that triggers a reboot after crashing. This can | |
1012 | also be set through CrashReboot= in systemd.conf. | |
1013 | ||
1014 | * The RuntimeDirectory= setting now understands unit | |
1015 | specifiers like %i or %f. | |
1016 | ||
fe08a30b LP |
1017 | * A new (still internal) libary API sd-ipv4acd has been added, |
1018 | that implements address conflict detection for IPv4. It's | |
1019 | based on code from sd-ipv4ll, and will be useful for | |
1020 | detecting DHCP address conflicts. | |
1021 | ||
bdba9227 DM |
1022 | * File descriptors passed during socket activation may now be |
1023 | named. A new API sd_listen_fds_with_names() is added to | |
a8eaaee7 | 1024 | access the names. The default names may be overridden, |
bdba9227 DM |
1025 | either in the .socket file using the FileDescriptorName= |
1026 | parameter, or by passing FDNAME= when storing the file | |
1027 | descriptors using sd_notify(). | |
fe08a30b | 1028 | |
d046fb93 LP |
1029 | * systemd-networkd gained support for: |
1030 | ||
0053598f | 1031 | - Setting the IPv6 Router Advertisement settings via |
edf4126f | 1032 | IPv6AcceptRouterAdvertisements= in .network files. |
d046fb93 LP |
1033 | |
1034 | - Configuring the HelloTimeSec=, MaxAgeSec= and | |
1035 | ForwardDelaySec= bridge parameters in .netdev files. | |
1036 | ||
1037 | - Configuring PreferredSource= for static routes in | |
edf4126f | 1038 | .network files. |
fe08a30b | 1039 | |
bdba9227 DM |
1040 | * The "ask-password" framework used to query for LUKS harddisk |
1041 | passwords or SSL passwords during boot gained support for | |
1042 | caching passwords in the kernel keyring, if it is | |
1043 | available. This makes sure that the user only has to type in | |
1044 | a passphrase once if there are multiple objects to unlock | |
1045 | with the same one. Previously, such password caching was | |
1046 | available only when Plymouth was used; this moves the | |
1047 | caching logic into the systemd codebase itself. The | |
1048 | "systemd-ask-password" utility gained a new --keyname= | |
1049 | switch to control which kernel keyring key to use for | |
1050 | caching a password in. This functionality is also useful for | |
1051 | enabling display managers such as gdm to automatically | |
1052 | unlock the user's GNOME keyring if its passphrase, the | |
1053 | user's password and the harddisk password are the same, if | |
1054 | gdm-autologin is used. | |
fe08a30b LP |
1055 | |
1056 | * When downloading tar or raw images using "machinectl | |
1057 | pull-tar" or "machinectl pull-raw", a matching ".nspawn" | |
1058 | file is now also downloaded, if it is available and stored | |
1059 | next to the image file. | |
c97e586d | 1060 | |
91d0d699 LP |
1061 | * Units of type ".socket" gained a new boolean setting |
1062 | Writable= which is only useful in conjunction with | |
1063 | ListenSpecial=. If true, enables opening the specified | |
1064 | special file in O_RDWR mode rather than O_RDONLY mode. | |
1065 | ||
1066 | * systemd-rfkill has been reworked to become a singleton | |
1067 | service that is activated through /dev/rfkill on each rfkill | |
1068 | state change and saves the settings to disk. This way, | |
1069 | systemd-rfkill is now compatible with devices that exist | |
1070 | only intermittendly, and even restores state if the previous | |
1071 | system shutdown was abrupt rather than clean. | |
1072 | ||
d046fb93 LP |
1073 | * The journal daemon gained support for vacuuming old journal |
1074 | files controlled by the number of files that shall remain, | |
1075 | in addition to the already existing control by size and by | |
1076 | date. This is useful as journal interleaving performance | |
6dd6a9c4 | 1077 | degrades with too many separate journal files, and allows |
d046fb93 LP |
1078 | putting an effective limit on them. The new setting defaults |
1079 | to 100, but this may be changed by setting SystemMaxFiles= | |
1080 | and RuntimeMaxFiles= in journald.conf. Also, the | |
1081 | "journalctl" tool gained the new --vacuum-files= switch to | |
1082 | manually vacuum journal files to leave only the specified | |
1083 | number of files in place. | |
c48eb61f | 1084 | |
bdba9227 DM |
1085 | * udev will now create /dev/disk/by-path links for ATA devices |
1086 | on kernels where that is supported. | |
c30f086f | 1087 | |
efce0ffe | 1088 | * Galician, Serbian, Turkish and Korean translations were added. |

5e8d4254 LP |
1113 | * The DHCP implementation of systemd-networkd gained a set of |
1114 | new features: | |
1115 | ||
1116 | - The DHCP server now supports emitting DNS and NTP | |
1117 | information. It may be enabled and configured via | |
1118 | EmitDNS=, DNS=, EmitNTP=, and NTP=. If transmission of DNS | |
1119 | and NTP information is enabled, but no servers are | |
1120 | configured, the corresponding uplink information (if there | |
1121 | is any) is propagated. | |
1122 | ||
1123 | - Server and client now support transmission and reception | |
1124 | of timezone information. It can be configured via the | |
1125 | newly introduced network options UseTimezone=, | |
1126 | EmitTimezone=, and Timezone=. Transmission of timezone | |
1127 | information is enabled between host and containers by | |
1128 | default now: the container will change its local timezone | |
1129 | to what the host has set. | |
1130 | ||
1131 | - Lease timeouts can now be configured via | |
1132 | MaxLeaseTimeSec= and DefaultLeaseTimeSec=. | |
1133 | ||
1134 | - The DHCP server improved on the stability of | |
1135 | leases. Clients are more likely to get the same lease | |
1136 | information back, even if the server loses state. | |
1137 | ||
1138 | - The DHCP server supports two new configuration options to | |
1139 | control the lease address pool metrics, PoolOffset= and | |
1140 | PoolSize=. | |
1141 | ||
1142 | * The encapsulation limit of tunnels in systemd-networkd may | |
1143 | now be configured via 'EncapsulationLimit='. It allows | |
1144 | modifying the maximum additional levels of encapsulation | |
1145 | that are permitted to be prepended to a packet. | |
1146 | ||
1147 | * systemd now supports the concept of user buses replacing | |
1148 | session buses, if used with dbus-1.10 (and enabled via dbus | |
1149 | --enable-user-session). It previously only supported this on | |
1150 | kdbus-enabled systems, and this release expands this to | |
1151 | 'dbus-daemon' systems. | |
1152 | ||
1153 | * systemd-networkd now supports predictable interface names | |
1154 | for virtio devices. | |
1155 | ||
1156 | * systemd now optionally supports the new Linux kernel | |
1157 | "unified" control group hierarchy. If enabled via the kernel | |
1158 | command-line option 'systemd.unified_cgroup_hierarchy=1', | |
1159 | systemd will try to mount the unified cgroup hierarchy | |
1160 | directly on /sys/fs/cgroup. If not enabled, or not | |
1161 | available, systemd will fall back to the legacy cgroup | |
1162 | hierarchy setup, as before. Host system and containers can | |
1163 | mix and match legacy and unified hierarchies as they | |
856ca72b | 1164 | wish. nspawn understands the $UNIFIED_CGROUP_HIERARCHY |
5e8d4254 LP |
1165 | environment variable to individually select the hierarchy to |
1166 | use for executed containers. By default, nspawn will use the | |
1167 | unified hierarchy for the containers if the host uses the | |
1168 | unified hierarchy, and the legacy hierarchy otherwise. | |
1169 | Please note that at this point the unified hierarchy is an | |
1170 | experimental kernel feature and is likely to change in one | |
1171 | of the next kernel releases. Therefore, it should not be | |
1172 | enabled by default in downstream distributions yet. The | |
1173 | minimum required kernel version for the unified hierarchy to | |
1174 | work is 4.2. Note that when the unified hierarchy is used | |
1175 | for the first time delegated access to controllers is | |
1176 | safe. Because of this systemd-nspawn containers will get | |
1177 | access to controllers now, as will systemd user | |
1178 | sessions. This means containers and user sessions may now | |
1179 | manage their own resources, partitioning up what the system | |
1180 | grants them. | |
1181 | ||
1182 | * A new special scope unit "init.scope" has been introduced | |
1183 | that encapsulates PID 1 of the system. It may be used to | |
1184 | determine resource usage and enforce resource limits on PID | |
1185 | 1 itself. PID 1 hence moved out of the root of the control | |
1186 | group tree. | |
1187 | ||
1188 | * The cgtop tool gained support for filtering out kernel | |
1189 | threads when counting tasks in a control group. Also, the | |
1190 | count of processes is now recursively summed up by | |
1191 | default. Two options -k and --recursive= have been added to | |
1192 | revert to old behaviour. The tool has also been updated to | |
1193 | work correctly in containers now. | |
1194 | ||
1195 | * systemd-nspawn's --bind= and --bind-ro= options have been | |
1196 | extended to allow creation of non-recursive bind mounts. | |
1197 | ||
c626bf1d DM |
1198 | * libsystemd gained two new calls sd_pid_get_cgroup() and |
1199 | sd_peer_get_cgroup() which return the control group path of | |
5e8d4254 LP |
1200 | a process or peer of a connected AF_UNIX socket. This |
1201 | function call is particularly useful when implementing | |
1202 | delegated subtrees support in the control group hierarchy. | |
1203 | ||
1204 | * The "sd-event" event loop API of libsystemd now supports | |
1205 | correct dequeuing of real-time signals, without losing | |
1206 | signal events. | |
1207 | ||
1208 | * When systemd requests a PolicyKit decision when managing | |
1209 | units it will now add additional fields to the request, | |
1210 | including unit name and desired operation. This enables more | |
1211 | powerful PolicyKit policies, that make decisions depending | |
1212 | on these parameters. | |
c9912c5e | 1213 | |
47f5a38c LP |
1214 | * nspawn learnt support for .nspawn settings files, that may |
1215 | accompany the image files or directories of containers, and | |
1216 | may contain additional settings for the container. This is | |
1217 | an alternative to configuring container parameters via the | |
1218 | nspawn command line. | |

1231 | CHANGES WITH 225: |
1232 | ||
5e8d4254 LP |
1233 | * machinectl gained a new verb 'shell' which opens a fresh |
1234 | shell on the target container or the host. It is similar to | |
1235 | the existing 'login' command of machinectl, but spawns the | |
1236 | shell directly without prompting for username or | |
1237 | password. The pseudo machine '.host' now refers to the local | |
1238 | host and is used by default. Hence, 'machinectl shell' can | |
1239 | be used as replacement for 'su -' which spawns a session as | |
1240 | a fresh systemd unit in a way that is fully isolated from | |
1241 | the originating session. | |
1242 | ||
1243 | * systemd-networkd learned to cope with private-zone DHCP | |
1244 | options and allows other programs to query the values. | |
1245 | ||
1246 | * SELinux access control when enabling/disabling units is no | |
1247 | longer enforced with this release. The previous | |
1248 | implementation was incorrect, and a new corrected | |
1249 | implementation is not yet available. As unit file operations | |
1250 | are still protected via PolicyKit and D-Bus policy this is | |
1251 | not a security problem. Yet, distributions which care about | |
1252 | optimal SELinux support should probably not stabilize on | |
1253 | this release. | |
1254 | ||
1255 | * sd-bus gained support for matches of type "arg0has=", that | |
1256 | test for membership of strings in string arrays sent in bus | |
1257 | messages. | |
1258 | ||
1259 | * systemd-resolved now dumps the contents of its DNS and LLMNR | |
1260 | caches to the logs on reception of the SIGUSR1 signal. This | |
1261 | is useful to debug DNS behaviour. | |
1262 | ||
1263 | * The coredumpctl tool gained a new --directory= option to | |
1264 | operate on journal files in a specific directory. | |
1265 | ||
1266 | * "systemctl reboot" and related commands gained a new | |
1267 | "--message=" option which may be used to set a free-text | |
1268 | wall message when shutting down or rebooting the | |
1269 | system. This message is also logged, which is useful for | |
1270 | figuring out the reason for a reboot or shutdown a | |
1271 | posteriori. | |
1272 | ||
1273 | * The "systemd-resolve-host" tool's -i switch now takes | |
1274 | network interface numbers as alternative to interface names. | |
1275 | ||
1276 | * A new unit file setting for services has been introduced: | |
1277 | UtmpMode= allows configuration of how precisely systemd | |
1278 | handles utmp and wtmp entries for the service if this is | |
1279 | enabled. This allows writing services that appear similar to | |
1280 | user sessions in the output of the "w", "who", "last" and | |
1281 | "lastlog" tools. | |
1282 | ||
1283 | * systemd-resolved will now locally synthesize DNS resource | |
1284 | records for the "localhost" and "gateway" domains as well as | |
1285 | the local hostname. This should ensure that clients querying | |
1286 | RRs via resolved will get similar results as those going via | |
1287 | NSS, if nss-myhostname is enabled. | |

5e8d4254 LP |
1309 | * systemd-networkd now supports Group Policy for vxlan |

1319 | CHANGES WITH 223: |
1320 | ||
1321 | * The python-systemd code has been removed from the systemd repository. | |
1322 | A new repository has been created which accommodates the code from | |
1323 | now on, and we kindly ask distributions to create a separate package | |
1324 | for this: https://github.com/systemd/python-systemd | |
1325 | ||
01608bc8 | 1326 | * The systemd daemon will now reload its main configuration |
e57eaef8 DH |
1327 | (/etc/systemd/system.conf) on daemon-reload. |
1328 | ||
1329 | * sd-dhcp now exposes vendor specific extensions via | |
1330 | sd_dhcp_lease_get_vendor_specific(). | |
1331 | ||
931618d0 DM |
1332 | * systemd-networkd gained a number of new configuration options. |
1333 | ||
1334 | - A new boolean configuration option for TAP devices called | |
37d54b93 | 1335 | 'VNetHeader='. If set, the IFF_VNET_HDR flag is set for the |
931618d0 DM |
1336 | device, thus allowing to send and receive GSO packets. |
1337 | ||
1338 | - A new tunnel configuration option called 'CopyDSCP='. | |
1339 | If enabled, the DSCP field of ip6 tunnels is copied into the | |
1340 | decapsulated packet. | |
1341 | ||
1342 | - A set of boolean bridge configuration options were added. | |
1343 | 'UseBPDU=', 'HairPin=', 'FastLeave=', 'AllowPortToBeRoot=', | |
1344 | and 'UnicastFlood=' are now parsed by networkd and applied to the | |
1345 | respective bridge link device via the respective IFLA_BRPORT_* | |
1346 | netlink attribute. | |
1347 | ||
1348 | - A new string configuration option to override the hostname sent | |
1349 | to a DHCP server, called 'Hostname='. If set and 'SendHostname=' | |
1350 | is true, networkd will use the configured hostname instead of the | |
1351 | system hostname when sending DHCP requests. | |
1352 | ||
1353 | - A new tunnel configuration option called 'IPv6FlowLabel='. If set, | |
1354 | networkd will configure the IPv6 flow-label of the tunnel device | |
1355 | according to RFC2460. | |
e57eaef8 | 1356 | |
f5f113f6 DH |
1357 | - The 'macvtap' virtual network devices are now supported, similar to |
1358 | the already supported 'macvlan' devices. | |
1359 | ||
e57eaef8 | 1360 | * systemd-resolved now implements RFC5452 to improve resilience against |
01608bc8 | 1361 | cache poisoning. Additionally, source port randomization is enabled |
e57eaef8 DH |
1362 | by default to further protect against DNS spoofing attacks. |
1363 | ||
1364 | * nss-mymachines now supports translating UIDs and GIDs of running | |
1365 | containers with user-namespaces enabled. If a container 'foo' | |
1366 | translates a host uid 'UID' to the container uid 'TUID', then | |
1367 | nss-mymachines will also map uid 'UID' to/from username 'vu-foo-TUID' | |
1368 | (with 'foo' and 'TUID' replaced accordingly). Similarly, groups are | |
1369 | mapped as 'vg-foo-TGID'. | |

5541c889 | 1385 | |
861b02eb KS |
1386 | * udev does not longer support the WAIT_FOR_SYSFS= key in udev rules. |
1387 | There are no known issues with current sysfs, and udev does not need | |
1388 | or should be used to work around such bugs. | |
1389 | ||
1390 | * udev does no longer enable USB HID power management. Several reports | |
1391 | indicate, that some devices cannot handle that setting. | |
0db83ad7 DH |
1392 | |
1393 | * The udev accelerometer helper was removed. The functionality | |
1394 | is now fully included in iio-sensor-proxy. But this means, | |
1395 | older iio-sensor-proxy versions will no longer provide | |
1396 | accelerometer/orientation data with this systemd version. | |
1397 | Please upgrade iio-sensor-proxy to version 1.0. | |
1398 | ||
5541c889 DH |
1399 | * networkd gained a new configuration option IPv6PrivacyExtensions= |
1400 | which enables IPv6 privacy extensions (RFC 4941, "Privacy Extensions | |
1401 | for Stateless Address") on selected networks. | |
1402 | ||
9b361114 DM |
1403 | * For the sake of fewer build-time dependencies and less code in the |
1404 | main repository, the python bindings are about to be removed in the | |
1405 | next release. A new repository has been created which accommodates | |
1406 | the code from now on, and we kindly ask distributions to create a | |
1407 | separate package for this. The removal will take place in v223. | |

1424 | CHANGES WITH 221: |
1425 | ||
470e72d4 | 1426 | * The sd-bus.h and sd-event.h APIs have now been declared |
5f92d24f | 1427 | stable and have been added to the official interface of |
470e72d4 LP |
1428 | libsystemd.so. sd-bus implements an alternative D-Bus client |
1429 | library, that is relatively easy to use, very efficient and | |
1430 | supports both classic D-Bus as well as kdbus as transport | |
1431 | backend. sd-event is a generic event loop abstraction that | |
1432 | is built around Linux epoll, but adds features such as event | |
0aee49d5 | 1433 | prioritization or efficient timer handling. Both APIs are good |
470e72d4 LP |
1434 | choices for C programs looking for a bus and/or event loop |
1435 | implementation that is minimal and does not have to be | |
5f92d24f | 1436 | portable to other kernels. |
0f0467e6 | 1437 | |
470e72d4 LP |
1438 | * kdbus support is no longer compile-time optional. It is now |
1439 | always built-in. However, it can still be disabled at | |
1440 | runtime using the kdbus=0 kernel command line setting, and | |
c6551464 | 1441 | that setting may be changed to default to off, by specifying |
470e72d4 LP |
1442 | --disable-kdbus at build-time. Note though that the kernel |
1443 | command line setting has no effect if the kdbus.ko kernel | |
1444 | module is not installed, in which case kdbus is (obviously) | |
1445 | also disabled. We encourage all downstream distributions to | |
0aee49d5 | 1446 | begin testing kdbus by adding it to the kernel images in the |
470e72d4 LP |
1447 | development distributions, and leaving kdbus support in |
1448 | systemd enabled. | |
0f0467e6 | 1449 | |
470e72d4 LP |
1450 | * The minimal required util-linux version has been bumped to |
1451 | 2.26. | |
1452 | ||
1453 | * Support for chkconfig (--enable-chkconfig) was removed in | |
0aee49d5 | 1454 | favor of calling an abstraction tool |
470e72d4 LP |
1455 | /lib/systemd/systemd-sysv-install. This needs to be |
1456 | implemented for your distribution. See "SYSV INIT.D SCRIPTS" | |
1457 | in README for details. | |
1458 | ||
1459 | * If there's a systemd unit and a SysV init script for the | |
1460 | same service name, and the user executes "systemctl enable" | |
1461 | for it (or a related call), then this will now enable both | |
1462 | (or execute the related operation on both), not just the | |
1463 | unit. | |
1464 | ||
1465 | * The libudev API documentation has been converted from gtkdoc | |
1466 | into man pages. | |
1467 | ||
1468 | * gudev has been removed from the systemd tree, it is now an | |
1469 | external project. | |
1470 | ||
1471 | * The systemd-cgtop tool learnt a new --raw switch to generate | |
0aee49d5 | 1472 | "raw" (machine parsable) output. |
470e72d4 LP |
1473 | |
1474 | * networkd's IPForwarding= .network file setting learnt the | |
1475 | new setting "kernel", which ensures that networkd does not | |
1476 | change the IP forwarding sysctl from the default kernel | |
1477 | state. | |
1478 | ||
1479 | * The systemd-logind bus API now exposes a new boolean | |
1480 | property "Docked" that reports whether logind considers the | |
1481 | system "docked", i.e. connected to a docking station or not. | |

1502 | CHANGES WITH 220: |
1503 | ||
f7a73a25 DH |
1504 | * The gudev library has been extracted into a separate repository |
1505 | available at: https://git.gnome.org/browse/libgudev/ | |
1506 | It is now managed as part of the Gnome project. Distributions | |
1507 | are recommended to pass --disable-gudev to systemd and use | |
1508 | gudev from the Gnome project instead. gudev is still included | |
1509 | in systemd, for now. It will be removed soon, though. Please | |
1510 | also see the announcement-thread on systemd-devel: | |
1511 | http://lists.freedesktop.org/archives/systemd-devel/2015-May/032070.html | |
1512 | ||
481a0aa2 LP |
1513 | * systemd now exposes a CPUUsageNSec= property for each |
1514 | service unit on the bus, that contains the overall consumed | |
1515 | CPU time of a service (the sum of what each process of the | |
1516 | service consumed). This value is only available if | |
1517 | CPUAccounting= is turned on for a service, and is then shown | |
1518 | in the "systemctl status" output. | |
1519 | ||
1520 | * Support for configuring alternative mappings of the old SysV | |
1521 | runlevels to systemd targets has been removed. They are now | |
29d1fcb4 | 1522 | hardcoded in a way that runlevels 2, 3, 4 all map to |
481a0aa2 LP |
1523 | multi-user.target and 5 to graphical.target (which |
1524 | previously was already the default behaviour). | |
1525 | ||
1526 | * The auto-mounter logic gained support for mount point | |
1527 | expiry, using a new TimeoutIdleSec= setting in .automount | |
1528 | units. (Also available as x-systemd.idle-timeout= in /etc/fstab). | |
1529 | ||
1530 | * The EFI System Partition (ESP) as mounted to /boot by | |
1531 | systemd-efi-boot-generator will now be unmounted | |
29d1fcb4 | 1532 | automatically after 2 minutes of not being used. This should |
481a0aa2 LP |
1533 | minimize the risk of ESP corruptions. |
1534 | ||
1535 | * New /etc/fstab options x-systemd.requires= and | |
1536 | x-systemd.requires-mounts-for= are now supported to express | |
1537 | additional dependencies for mounts. This is useful for | |
1538 | journalling file systems that support external journal | |
1539 | devices or overlay file systems that require underlying file | |
1540 | systems to be mounted. | |
1541 | ||
1542 | * systemd does not support direct live-upgrades (via systemctl | |
1543 | daemon-reexec) from versions older than v44 anymore. As no | |
1544 | distribution we are aware of shipped such old versions in a | |
1545 | stable release this should not be problematic. | |
1546 | ||
1547 | * When systemd forks off a new per-connection service instance | |
1548 | it will now set the $REMOTE_ADDR environment variable to the | |
1549 | remote IP address, and $REMOTE_PORT environment variable to | |
1550 | the remote IP port. This behaviour is similar to the | |
1551 | corresponding environment variables defined by CGI. | |
1552 | ||
1553 | * systemd-networkd gained support for uplink failure | |
1554 | detection. The BindCarrier= option allows binding interface | |
1555 | configuration dynamically to the link sense of other | |
1556 | interfaces. This is useful to achieve behaviour like in | |
1557 | network switches. | |
1558 | ||
1559 | * systemd-networkd gained support for configuring the DHCP | |
1560 | client identifier to use when requesting leases. | |
1561 | ||
1562 | * systemd-networkd now has a per-network UseNTP= option to | |
1563 | configure whether NTP server information acquired via DHCP | |
1564 | is passed on to services like systemd-timesyncd. | |
1565 | ||
1566 | * systemd-networkd gained support for vti6 tunnels. | |
1567 | ||
1579dd2c LP |
1568 | * Note that systemd-networkd manages the sysctl variable |
1569 | /proc/sys/net/ipv[46]/conf/*/forwarding for each interface | |
1570 | it is configured for since v219. The variable controls IP | |
1571 | forwarding, and is a per-interface alternative to the global | |
1572 | /proc/sys/net/ipv[46]/ip_forward. This setting is | |
1573 | configurable in the IPForward= option, which defaults to | |
1574 | "no". This means if networkd is used for an interface it is | |
1575 | no longer sufficient to set the global sysctl option to turn | |
1576 | on IP forwarding! Instead, the .network file option | |
1577 | IPForward= needs to be turned on! Note that the | |
1578 | implementation of this behaviour was broken in v219 and has | |
1579 | been fixed in v220. | |
1580 | ||
481a0aa2 LP |
1581 | * Many bonding and vxlan options are now configurable in |
1582 | systemd-networkd. | |
1583 | ||
1584 | * systemd-nspawn gained a new --property= setting to set unit | |
1585 | properties for the container scope. This is useful for | |
1586 | setting resource parameters (e.g "CPUShares=500") on | |
1587 | containers started from the command line. | |
1588 | ||
1589 | * systemd-nspawn gained a new --private-users= switch to make | |
1590 | use of user namespacing available on recent Linux kernels. | |
1591 | ||
1592 | * systemd-nspawn may now be called as part of a shell pipeline | |
1593 | in which case the pipes used for stdin and stdout are passed | |
1594 | directly to the process invoked in the container, without | |
1595 | indirection via a pseudo tty. | |
1596 | ||
1597 | * systemd-nspawn gained a new switch to control the UNIX | |
1598 | signal to use when killing the init process of the container | |
1599 | when shutting down. | |
1600 | ||
1601 | * systemd-nspawn gained a new --overlay= switch for mounting | |
1602 | overlay file systems into the container using the new kernel | |
1603 | overlayfs support. | |
1604 | ||
1605 | * When a container image is imported via systemd-importd and | |
1606 | the host file system is not btrfs, a loopback block device | |
1607 | file is created in /var/lib/machines.raw with a btrfs file | |
1608 | system inside. It is then mounted to /var/lib/machines to | |
1609 | enable btrfs features for container management. The loopback | |
1610 | file and btrfs file system is grown as needed when container | |
1611 | images are imported via systemd-importd. | |
1612 | ||
1613 | * systemd-machined/systemd-importd gained support for btrfs | |
1614 | quota, to enforce container disk space limits on disk. This | |
1615 | is exposed in "machinectl set-limit". | |
1616 | ||
1617 | * systemd-importd now can import containers from local .tar, | |
1618 | .raw and .qcow2 images, and export them to .tar and .raw. It | |
1619 | can also import dkr v2 images now from the network (on top | |
1620 | of v1 as before). | |
1621 | ||
1622 | * systemd-importd gained support for verifying downloaded | |
1623 | images with gpg2 (previously only gpg1 was supported). | |
1624 | ||
1625 | * systemd-machined, systemd-logind, systemd: most bus calls | |
1626 | are now accessible to unprivileged processes via | |
1627 | PolicyKit. Also, systemd-logind will now allow users to kill | |
1628 | their own sessions without further privileges or | |
1629 | authorization. | |
1630 | ||
1631 | * systemd-shutdownd has been removed. This service was | |
1632 | previously responsible for implementing scheduled shutdowns | |
1633 | as exposed in /usr/bin/shutdown's time parameter. This | |
1634 | functionality has now been moved into systemd-logind and is | |
1635 | accessible via a bus interface. | |
1636 | ||
1637 | * "systemctl reboot" gained a new switch --firmware-setup that | |
1638 | can be used to reboot into the EFI firmware setup, if that | |
1639 | is available. systemd-logind now exposes an API on the bus | |
1640 | to trigger such reboots, in case graphical desktop UIs want | |
1641 | to cover this functionality. | |
1642 | ||
1643 | * "systemctl enable", "systemctl disable" and "systemctl mask" | |
1579dd2c | 1644 | now support a new "--now" switch. If specified the units |
481a0aa2 LP |
1645 | that are enabled will also be started, and the ones |
1646 | disabled/masked also stopped. | |
1647 | ||
1648 | * The Gummiboot EFI boot loader tool has been merged into | |
1a2d5fbe DH |
1649 | systemd, and renamed to "systemd-boot". The bootctl tool has been |
1650 | updated to support systemd-boot. | |
481a0aa2 LP |
1651 | |
1652 | * An EFI kernel stub has been added that may be used to create | |
1653 | kernel EFI binaries that contain not only the actual kernel, | |
1654 | but also an initrd, boot splash, command line and OS release | |
1655 | information. This combined binary can then be signed as a | |
1656 | single image, so that the firmware can verify it all in one | |
1a2d5fbe | 1657 | step. systemd-boot has special support for EFI binaries created |
481a0aa2 LP |
1658 | like this and can extract OS release information from them |
1659 | and show them in the boot menu. This functionality is useful | |
1660 | to implement cryptographically verified boot schemes. | |
1661 | ||
1662 | * Optional support has been added to systemd-fsck to pass | |
1663 | fsck's progress report to an AF_UNIX socket in the file | |
1664 | system. | |
1665 | ||
1666 | * udev will no longer create device symlinks for all block | |
1667 | devices by default. A blacklist for excluding special block | |
1668 | devices from this logic has been turned into a whitelist | |
1669 | that requires picking block devices explicitly that require | |
1670 | device symlinks. | |
1671 | ||
1672 | * A new (currently still internal) API sd-device.h has been | |
1673 | added to libsystemd. This modernized API is supposed to | |
1674 | replace libudev eventually. In fact, already much of libudev | |
1675 | is now just a wrapper around sd-device.h. | |
1676 | ||
1677 | * A new hwdb database for storing metadata about pointing | |
1678 | stick devices has been added. | |
1679 | ||
1680 | * systemd-tmpfiles gained support for setting file attributes | |
1681 | similar to the "chattr" tool with new 'h' and 'H' lines. | |
1682 | ||
1683 | * systemd-journald will no longer unconditionally set the | |
1684 | btrfs NOCOW flag on new journal files. This is instead done | |
1685 | with tmpfiles snippet using the new 'h' line type. This | |
1686 | allows easy disabling of this logic, by masking the | |
1687 | journal-nocow.conf tmpfiles file. | |
1688 | ||
1689 | * systemd-journald will now translate audit message types to | |
1690 | human readable identifiers when writing them to the | |
1691 | journal. This should improve readability of audit messages. | |
1692 | ||
1693 | * The LUKS logic gained support for the offset= and skip= | |
1694 | options in /etc/crypttab, as previously implemented by | |
1695 | Debian. | |
1696 | ||
1697 | * /usr/lib/os-release gained a new optional field VARIANT= for | |
1698 | distributions that support multiple variants (such as a | |
1699 | desktop edition, a server edition, ...) | |

615aaf41 LP |
1731 | CHANGES WITH 219: |
1732 | ||
615aaf41 LP |
1733 | * Introduce a new API "sd-hwdb.h" for querying the hardware |
1734 | metadata database. With this minimal interface one can query | |
1735 | and enumerate the udev hwdb, decoupled from the old libudev | |
1736 | library. libudev's interface for this is now only a wrapper | |
1737 | around sd-hwdb. A new tool systemd-hwdb has been added to | |
1738 | interface with and update the database. | |
1739 | ||
1740 | * When any of systemd's tools copies files (for example due to | |
1741 | tmpfiles' C lines) a btrfs reflink will attempted first, | |
1742 | before bytewise copying is done. | |
1743 | ||
1744 | * systemd-nspawn gained a new --ephemeral switch. When | |
1745 | specified a btrfs snapshot is taken of the container's root | |
1746 | directory, and immediately removed when the container | |
1747 | terminates again. Thus, a container can be started whose | |
1748 | changes never alter the container's root directory, and are | |
1749 | lost on container termination. This switch can also be used | |
1750 | for starting a container off the root file system of the | |
1751 | host without affecting the host OS. This switch is only | |
1752 | available on btrfs file systems. | |
1753 | ||
1754 | * systemd-nspawn gained a new --template= switch. It takes the | |
1755 | path to a container tree to use as template for the tree | |
7edecf21 | 1756 | specified via --directory=, should that directory be |
615aaf41 LP |
1757 | missing. This allows instantiating containers dynamically, |
1758 | on first run. This switch is only available on btrfs file | |
1759 | systems. | |
1760 | ||
1761 | * When a .mount unit refers to a mount point on which multiple | |
1762 | mounts are stacked, and the .mount unit is stopped all of | |
1763 | the stacked mount points will now be unmounted until no | |
1764 | mount point remains. | |
1765 | ||
1766 | * systemd now has an explicit notion of supported and | |
1767 | unsupported unit types. Jobs enqueued for unsupported unit | |
1768 | types will now fail with an "unsupported" error code. More | |
1769 | specifically .swap, .automount and .device units are not | |
1770 | supported in containers, .busname units are not supported on | |
1771 | non-kdbus systems. .swap and .automount are also not | |
1772 | supported if their respective kernel compile time options | |
1773 | are disabled. | |
1774 | ||
1775 | * machinectl gained support for two new "copy-from" and | |
1776 | "copy-to" commands for copying files from a running | |
1777 | container to the host or vice versa. | |
1778 | ||
1779 | * machinectl gained support for a new "bind" command to bind | |
1780 | mount host directories into local containers. This is | |
1781 | currently only supported for nspawn containers. | |
1782 | ||
1783 | * networkd gained support for configuring bridge forwarding | |
1784 | database entries (fdb) from .network files. | |
1785 | ||
1786 | * A new tiny daemon "systemd-importd" has been added that can | |
1787 | download container images in tar, raw, qcow2 or dkr formats, | |
1788 | and make them available locally in /var/lib/machines, so | |
1789 | that they can run as nspawn containers. The daemon can GPG | |
1790 | verify the downloads (not supported for dkr, since it has no | |
1791 | provisions for verifying downloads). It will transparently | |
1792 | decompress bz2, xz, gzip compressed downloads if necessary, | |
1793 | and restore sparse files on disk. The daemon uses privilege | |
1794 | separation to ensure the actual download logic runs with | |
94e5ba37 | 1795 | fewer privileges than the daemon itself. machinectl has |
615aaf41 LP |
1796 | gained new commands "pull-tar", "pull-raw" and "pull-dkr" to |
1797 | make the functionality of importd available to the | |
1798 | user. With this in place the Fedora and Ubuntu "Cloud" | |
1799 | images can be downloaded and booted as containers unmodified | |
1800 | (the Fedora images lack the appropriate GPG signature files | |
1801 | currently, so they cannot be verified, but this will change | |
1802 | soon, hopefully). Note that downloading images is currently | |
1803 | only fully supported on btrfs. | |
1804 | ||
1805 | * machinectl is now able to list container images found in | |
1806 | /var/lib/machines, along with some metadata about sizes of | |
1807 | disk and similar. If the directory is located on btrfs and | |
1808 | quota is enabled, this includes quota display. A new command | |
1809 | "image-status" has been added that shows additional | |
1810 | information about images. | |
1811 | ||
1812 | * machinectl is now able to clone container images | |
1813 | efficiently, if the underlying file system (btrfs) supports | |
f59dba26 | 1814 | it, with the new "machinectl clone" command. It also |
615aaf41 LP |
1815 | gained commands for renaming and removing images, as well as |
1816 | marking them read-only or read-write (supported also on | |
1817 | legacy file systems). | |
1818 | ||
1819 | * networkd gained support for collecting LLDP network | |
1820 | announcements, from hardware that supports this. This is | |
1821 | shown in networkctl output. | |
1822 | ||
1823 | * systemd-run gained support for a new -t (--pty) switch for | |
1824 | invoking a binary on a pty whose input and output is | |
1825 | connected to the invoking terminal. This allows executing | |
1826 | processes as system services while interactively | |
1827 | communicating with them via the terminal. Most interestingly | |
1828 | this is supported across container boundaries. Invoking | |
1829 | "systemd-run -t /bin/bash" is an alternative to running a | |
1830 | full login session, the difference being that the former | |
1831 | will not register a session, nor go through the PAM session | |
1832 | setup. | |
1833 | ||
1834 | * tmpfiles gained support for a new "v" line type for creating | |
1835 | btrfs subvolumes. If the underlying file system is a legacy | |
1836 | file system, this automatically degrades to creating a | |
1837 | normal directory. Among others /var/lib/machines is now | |
1838 | created like this at boot, should it be missing. | |
1839 | ||
1840 | * The directory /var/lib/containers/ has been deprecated and | |
1841 | been replaced by /var/lib/machines. The term "machines" has | |
1842 | been used in the systemd context as generic term for both | |
1843 | VMs and containers, and hence appears more appropriate for | |
1844 | this, as the directory can also contain raw images bootable | |
1845 | via qemu/kvm. | |
1846 | ||
1847 | * systemd-nspawn when invoked with -M but without --directory= | |
1848 | or --image= is now capable of searching for the container | |
1849 | root directory, subvolume or disk image automatically, in | |
1850 | /var/lib/machines. systemd-nspawn@.service has been updated | |
1851 | to make use of this, thus allowing it to be used for raw | |
1852 | disk images, too. | |
1853 | ||
1854 | * A new machines.target unit has been introduced that is | |
1855 | supposed to group all containers/VMs invoked as services on | |
1856 | the system. systemd-nspawn@.service has been updated to | |
1857 | integrate with that. | |
1858 | ||
1859 | * machinectl gained a new "start" command, for invoking a | |
1860 | container as a service. "machinectl start foo" is mostly | |
1861 | equivalent to "systemctl start systemd-nspawn@foo.service", | |
1862 | but handles escaping in a nicer way. | |
1863 | ||
1864 | * systemd-nspawn will now mount most of the cgroupfs tree | |
1865 | read-only into each container, with the exception of the | |
1866 | container's own subtree in the name=systemd hierarchy. | |
1867 | ||
1868 | * journald now sets the special FS_NOCOW file flag for its | |
1869 | journal files. This should improve performance on btrfs, by | |
1870 | avoiding heavy fragmentation when journald's write-pattern | |
1871 | is used on COW file systems. It degrades btrfs' data | |
1872 | integrity guarantees for the files to the same levels as for | |
1873 | ext3/ext4 however. This should be OK though as journald does | |
1874 | its own data integrity checks and all its objects are | |
1875 | checksummed on disk. Also, journald should handle btrfs disk | |
1876 | full events a lot more gracefully now, by processing SIGBUS | |
1877 | errors, and not relying on fallocate() anymore. | |
1878 | ||
1879 | * When journald detects that journal files it is writing to | |
1880 | have been deleted it will immediately start new journal | |
1881 | files. | |
1882 | ||
1883 | * systemd now provides a way to store file descriptors | |
1884 | per-service in PID 1.This is useful for daemons to ensure | |
1885 | that fds they require are not lost during a daemon | |
94e5ba37 | 1886 | restart. The fds are passed to the daemon on the next |
615aaf41 LP |
1887 | invocation in the same way socket activation fds are |
1888 | passed. This is now used by journald to ensure that the | |
1889 | various sockets connected to all the system's stdout/stderr | |
1890 | are not lost when journald is restarted. File descriptors | |
1891 | may be stored in PID 1 via the sd_pid_notify_with_fds() API, | |
1892 | an extension to sd_notify(). Note that a limit is enforced | |
1893 | on the number of fds a service can store in PID 1, and it | |
1894 | defaults to 0, so that no fds may be stored, unless this is | |
1895 | explicitly turned on. | |
1896 | ||
1897 | * The default TERM variable to use for units connected to a | |
1898 | terminal, when no other value is explicitly is set is now | |
1899 | vt220 rather than vt102. This should be fairly safe still, | |
1900 | but allows PgUp/PgDn work. | |
1901 | ||
1902 | * The /etc/crypttab option header= as known from Debian is now | |
1903 | supported. | |
1904 | ||
1905 | * "loginctl user-status" and "loginctl session-status" will | |
1906 | now show the last 10 lines of log messages of the | |
1907 | user/session following the status output. Similar, | |
1908 | "machinectl status" will show the last 10 log lines | |
1909 | associated with a virtual machine or container | |
1910 | service. (Note that this is usually not the log messages | |
1911 | done in the VM/container itself, but simply what the | |
1912 | container manager logs. For nspawn this includes all console | |
1913 | output however.) | |
1914 | ||
1915 | * "loginctl session-status" without further argument will now | |
1916 | show the status of the session of the caller. Similar, | |
1917 | "lock-session", "unlock-session", "activate", | |
1918 | "enable-linger", "disable-linger" may now be called without | |
1919 | session/user parameter in which case they apply to the | |
1920 | caller's session/user. | |
1921 | ||
1922 | * An X11 session scriptlet is now shipped that uploads | |
1923 | $DISPLAY and $XAUTHORITY into the environment of the systemd | |
1924 | --user daemon if a session begins. This should improve | |
1925 | compatibility with X11 enabled applications run as systemd | |
1926 | user services. | |
1927 | ||
1928 | * Generators are now subject to masking via /etc and /run, the | |
1929 | same way as unit files. | |
1930 | ||
1931 | * networkd .network files gained support for configuring | |
1932 | per-link IPv4/IPv6 packet forwarding as well as IPv4 | |
1933 | masquerading. This is by default turned on for veth links to | |
1934 | containers, as registered by systemd-nspawn. This means that | |
1935 | nspawn containers run with --network-veth will now get | |
1936 | automatic routed access to the host's networks without any | |
1937 | further configuration or setup, as long as networkd runs on | |
1938 | the host. | |
1939 | ||
1940 | * systemd-nspawn gained the --port= (-p) switch to expose TCP | |
1941 | or UDP posts of a container on the host. With this in place | |
1942 | it is possible to run containers with private veth links | |
1943 | (--network-veth), and have their functionality exposed on | |
1944 | the host as if their services were running directly on the | |
1945 | host. | |
1946 | ||
dd2fd155 | 1947 | * systemd-nspawn's --network-veth switch now gained a short |
615aaf41 LP |
1948 | version "-n", since with the changes above it is now truly |
1949 | useful out-of-the-box. The systemd-nspawn@.service has been | |
1950 | updated to make use of it too by default. | |
1951 | ||
1952 | * systemd-nspawn will now maintain a per-image R/W lock, to | |
1953 | ensure that the same image is not started more than once | |
1954 | writable. (It's OK to run an image multiple times | |
1955 | simultaneously in read-only mode.) | |
1956 | ||
1957 | * systemd-nspawn's --image= option is now capable of | |
1958 | dissecting and booting MBR and GPT disk images that contain | |
1959 | only a single active Linux partition. Previously it | |
1960 | supported only GPT disk images with proper GPT type | |
1961 | IDs. This allows running cloud images from major | |
1962 | distributions directly with systemd-nspawn, without | |
1963 | modification. | |
1964 | ||
1965 | * In addition to collecting mouse dpi data in the udev | |
1966 | hardware database, there's now support for collecting angle | |
1967 | information for mouse scroll wheels. The database is | |
7edecf21 | 1968 | supposed to guarantee similar scrolling behavior on mice |
615aaf41 LP |
1969 | that it knows about. There's also support for collecting |
1970 | information about Touchpad types. | |
1971 | ||
1972 | * udev's input_id built-in will now also collect touch screen | |
1973 | dimension data and attach it to probed devices. | |
1974 | ||
1975 | * /etc/os-release gained support for a Distribution Privacy | |
1976 | Policy link field. | |
1977 | ||
1978 | * networkd gained support for creating "ipvlan", "gretap", | |
1979 | "ip6gre", "ip6gretap" and "ip6tnl" network devices. | |
1980 | ||
1981 | * systemd-tmpfiles gained support for "a" lines for setting | |
1982 | ACLs on files. | |
1983 | ||
1984 | * systemd-nspawn will now mount /tmp in the container to | |
1985 | tmpfs, automatically. | |
1986 | ||
1987 | * systemd now exposes the memory.usage_in_bytes cgroup | |
1988 | attribute and shows it for each service in the "systemctl | |
1989 | status" output, if available. | |
1990 | ||
1991 | * When the user presses Ctrl-Alt-Del more than 7x within 2s an | |
1992 | immediate reboot is triggered. This useful if shutdown is | |
1993 | hung and is unable to complete, to expedite the | |
1994 | operation. Note that this kind of reboot will still unmount | |
1995 | all file systems, and hence should not result in fsck being | |
1996 | run on next reboot. | |
1997 | ||
1998 | * A .device unit for an optical block device will now be | |
1999 | considered active only when a medium is in the drive. Also, | |
2000 | mount units are now bound to their backing devices thus | |
2001 | triggering automatic unmounting when devices become | |
2002 | unavailable. With this in place systemd will now | |
2003 | automatically unmount left-over mounts when a CD-ROM is | |
2004 | ejected or an USB stick is yanked from the system. | |
2005 | ||
2006 | * networkd-wait-online now has support for waiting for | |
2007 | specific interfaces only (with globbing), and for giving up | |
2008 | after a configurable timeout. | |
2009 | ||
2010 | * networkd now exits when idle. It will be automatically | |
2011 | restarted as soon as interfaces show up, are removed or | |
2012 | change state. networkd will stay around as long as there is | |
2013 | at least one DHCP state machine or similar around, that keep | |
2014 | it non-idle. | |
2015 | ||
2016 | * networkd may now configure IPv6 link-local addressing in | |
2017 | addition to IPv4 link-local addressing. | |
2018 | ||
2019 | * The IPv6 "token" for use in SLAAC may now be configured for | |
2020 | each .network interface in networkd. | |
2021 | ||
2022 | * Routes configured with networkd may now be assigned a scope | |
2023 | in .network files. | |
2024 | ||
2025 | * networkd's [Match] sections now support globbing and lists | |
2026 | of multiple space-separated matches per item. | |

2055 | CHANGES WITH 218: |
2056 | ||
f9e00a9f LP |
2057 | * When querying unit file enablement status (for example via |
2058 | "systemctl is-enabled"), a new state "indirect" is now known | |
2059 | which indicates that a unit might not be enabled itself, but | |
c7683ffb | 2060 | another unit listed in its Also= setting might be. |
f9e00a9f LP |
2061 | |
2062 | * Similar to the various existing ConditionXYZ= settings for | |
b938cb90 | 2063 | units, there are now matching AssertXYZ= settings. While |
f9e00a9f LP |
2064 | failing conditions cause a unit to be skipped, but its job |
2065 | to succeed, failing assertions declared like this will cause | |
2066 | a unit start operation and its job to fail. | |
2067 | ||
2068 | * hostnamed now knows a new chassis type "embedded". | |
2069 | ||
2070 | * systemctl gained a new "edit" command. When used on a unit | |
b938cb90 | 2071 | file, this allows extending unit files with .d/ drop-in |
f9e00a9f LP |
2072 | configuration snippets or editing the full file (after |
2073 | copying it from /usr/lib to /etc). This will invoke the | |
2074 | user's editor (as configured with $EDITOR), and reload the | |
2075 | modified configuration after editing. | |
2076 | ||
2077 | * "systemctl status" now shows the suggested enablement state | |
2078 | for a unit, as declared in the (usually vendor-supplied) | |
2079 | system preset files. | |
2080 | ||
2081 | * nss-myhostname will now resolve the single-label host name | |
2082 | "gateway" to the locally configured default IP routing | |
2083 | gateways, ordered by their metrics. This assigns a stable | |
2084 | name to the used gateways, regardless which ones are | |
2085 | currently configured. Note that the name will only be | |
2086 | resolved after all other name sources (if nss-myhostname is | |
2087 | configured properly) and should hence not negatively impact | |
2088 | systems that use the single-label host name "gateway" in | |
2089 | other contexts. | |
2090 | ||
2091 | * systemd-inhibit now allows filtering by mode when listing | |
2092 | inhibitors. | |
2093 | ||
122676c9 | 2094 | * Scope and service units gained a new "Delegate" boolean |
b938cb90 | 2095 | property, which, when set, allows processes running inside the |
122676c9 LP |
2096 | unit to further partition resources. This is primarily |
2097 | useful for systemd user instances as well as container | |
2098 | managers. | |
f9e00a9f LP |
2099 | |
2100 | * journald will now pick up audit messages directly from | |
2101 | the kernel, and log them like any other log message. The | |
2102 | audit fields are split up and fully indexed. This means that | |
2103 | journalctl in many ways is now a (nicer!) alternative to | |
2104 | ausearch, the traditional audit client. Note that this | |
b938cb90 | 2105 | implements only a minimal audit client. If you want the |
f9e00a9f LP |
2106 | special audit modes like reboot-on-log-overflow, please use |
2107 | the traditional auditd instead, which can be used in | |
2108 | parallel to journald. | |
2109 | ||
2110 | * The ConditionSecurity= unit file option now understands the | |
2111 | special string "audit" to check whether auditing is | |
2112 | available. | |
2113 | ||
2114 | * journalctl gained two new commands --vacuum-size= and | |
2115 | --vacuum-time= to delete old journal files until the | |
a8eaaee7 | 2116 | remaining ones take up no more than the specified size on disk, |
f9e00a9f LP |
2117 | or are not older than the specified time. |
2118 | ||
2119 | * A new, native PPPoE library has been added to sd-network, | |
2120 | systemd's library of light-weight networking protocols. This | |
2121 | library will be used in a future version of networkd to | |
2122 | enable PPPoE communication without an external pppd daemon. | |
2123 | ||
2124 | * The busctl tool now understands a new "capture" verb that | |
2125 | works similar to "monitor", but writes a packet capture | |
2126 | trace to STDOUT that can be redirected to a file which is | |
2127 | compatible with libcap's capture file format. This can then | |
2128 | be loaded in Wireshark and similar tools to inspect bus | |
2129 | communication. | |
2130 | ||
2131 | * The busctl tool now understands a new "tree" verb that shows | |
2132 | the object trees of a specific service on the bus, or of all | |
2133 | services. | |
2134 | ||
2135 | * The busctl tool now understands a new "introspect" verb that | |
2136 | shows all interfaces and members of objects on the bus, | |
2137 | including their signature and values. This is particularly | |
2138 | useful to get more information about bus objects shown by | |
2139 | the new "busctl tree" command. | |
2140 | ||
2141 | * The busctl tool now understands new verbs "call", | |
2142 | "set-property" and "get-property" for invoking bus method | |
2143 | calls, setting and getting bus object properties in a | |
2144 | friendly way. | |
2145 | ||
2146 | * busctl gained a new --augment-creds= argument that controls | |
2147 | whether the tool shall augment credential information it | |
2148 | gets from the bus with data from /proc, in a possibly | |
2149 | race-ful way. | |
2150 | ||
2151 | * nspawn's --link-journal= switch gained two new values | |
2152 | "try-guest" and "try-host" that work like "guest" and | |
17c29493 | 2153 | "host", but do not fail if the host has no persistent |
f9e00a9f LP |
2154 | journalling enabled. -j is now equivalent to |
2155 | --link-journal=try-guest. | |
2156 | ||
2157 | * macvlan network devices created by nspawn will now have | |
2158 | stable MAC addresses. | |
2159 | ||
2160 | * A new SmackProcessLabel= unit setting has been added, which | |
2161 | controls the SMACK security label processes forked off by | |
2162 | the respective unit shall use. | |
2163 | ||
d4f5a1f4 DH |
2164 | * If compiled with --enable-xkbcommon, systemd-localed will |
2165 | verify x11 keymap settings by compiling the given keymap. It | |
2166 | will spew out warnings if the compilation fails. This | |
2167 | requires libxkbcommon to be installed. | |
2168 | ||
b938cb90 | 2169 | * When a coredump is collected, a larger number of metadata |
f9e00a9f | 2170 | fields is now collected and included in the journal records |
b938cb90 | 2171 | created for it. More specifically, control group membership, |
f9e00a9f LP |
2172 | environment variables, memory maps, working directory, |
2173 | chroot directory, /proc/$PID/status, and a list of open file | |
2174 | descriptors is now stored in the log entry. | |
2175 | ||
17c29493 | 2176 | * The udev hwdb now contains DPI information for mice. For |
f9e00a9f LP |
2177 | details see: |
2178 | ||
2179 | http://who-t.blogspot.de/2014/12/building-a-dpi-database-for-mice.html | |
2180 | ||
2181 | * All systemd programs that read standalone configuration | |
2182 | files in /etc now also support a corresponding series of | |
997b2b43 JT |
2183 | .conf.d configuration directories in /etc/, /run/, |
2184 | /usr/local/lib/, /usr/lib/, and (if configured with | |
2185 | --enable-split-usr) /lib/. In particular, the following | |
2186 | configuration files now have corresponding configuration | |
2187 | directories: system.conf user.conf, logind.conf, | |
2188 | journald.conf, sleep.conf, bootchart.conf, coredump.conf, | |
2189 | resolved.conf, timesyncd.conf, journal-remote.conf, and | |
2190 | journal-upload.conf. Note that distributions should use the | |
2191 | configuration directories in /usr/lib/; the directories in | |
2192 | /etc/ are reserved for the system administrator. | |
2193 | ||
f9e00a9f LP |
2194 | * systemd-rfkill will no longer take the rfkill device name |
2195 | into account when storing rfkill state on disk, as the name | |
2196 | might be dynamically assigned and not stable. Instead, the | |
2197 | ID_PATH udev variable combined with the rfkill type (wlan, | |
2198 | bluetooth, ...) is used. | |
2199 | ||
2200 | * A new service systemd-machine-id-commit.service has been | |
2201 | added. When used on systems where /etc is read-only during | |
2202 | boot, and /etc/machine-id is not initialized (but an empty | |
2203 | file), this service will copy the temporary machine ID | |
2204 | created as replacement into /etc after the system is fully | |
2205 | booted up. This is useful for systems that are freshly | |
2206 | installed with a non-initialized machine ID, but should get | |
2207 | a fixed machine ID for subsequent boots. | |
2208 | ||
2209 | * networkd's .netdev files now provide a large set of | |
a8eaaee7 | 2210 | configuration parameters for VXLAN devices. Similarly, the |
f9e00a9f LP |
2211 | bridge port cost parameter is now configurable in .network |
2212 | files. There's also new support for configuring IP source | |
2213 | routing. networkd .link files gained support for a new | |
2214 | OriginalName= match that is useful to match against the | |
2215 | original interface name the kernel assigned. .network files | |
2216 | may include MTU= and MACAddress= fields for altering the MTU | |
2217 | and MAC address while being connected to a specific network | |
2218 | interface. | |
2219 | ||
2220 | * The LUKS logic gained supported for configuring | |
2221 | UUID-specific key files. There's also new support for naming | |
2222 | LUKS device from the kernel command line, using the new | |
2223 | luks.name= argument. | |
2224 | ||
2225 | * Timer units may now be transiently created via the bus API | |
2226 | (this was previously already available for scope and service | |
2227 | units). In addition it is now possible to create multiple | |
2228 | transient units at the same time with a single bus call. The | |
2229 | "systemd-run" tool has been updated to make use of this for | |
2230 | running commands on a specified time, in at(1)-style. | |
2231 | ||
2232 | * tmpfiles gained support for "t" lines, for assigning | |
2233 | extended attributes to files. Among other uses this may be | |
2234 | used to assign SMACK labels to files. | |
2235 | ||

b62a309a ZJS |
2257 | CHANGES WITH 217: |
2258 | ||
78b6b7ce LP |
2259 | * journalctl gained the new options -t/--identifier= to match |
2260 | on the syslog identifier (aka "tag"), as well as --utc to | |
2261 | show log timestamps in the UTC timezone. journalctl now also | |
2262 | accepts -n/--lines=all to disable line capping in a pager. | |
b62a309a | 2263 | |
a65b8245 ZJS |
2264 | * journalctl gained a new switch, --flush, that synchronously |
2265 | flushes logs from /run/log/journal to /var/log/journal if | |
2266 | persistent storage is enabled. systemd-journal-flush.service | |
2267 | now waits until the operation is complete. | |
2a97b03b | 2268 | |
b62a309a ZJS |
2269 | * Services can notify the manager before they start a reload |
2270 | (by sending RELOADING=1) or shutdown (by sending | |
4bdc60cb LP |
2271 | STOPPING=1). This allows the manager to track and show the |
2272 | internal state of daemons and closes a race condition when | |
78b6b7ce | 2273 | the process is still running but has closed its D-Bus |
4bdc60cb | 2274 | connection. |
b62a309a | 2275 | |
78b6b7ce LP |
2276 | * Services with Type=oneshot do not have to have any ExecStart |
2277 | commands anymore. | |
b62a309a ZJS |
2278 | |
2279 | * User units are now loaded also from | |
2280 | $XDG_RUNTIME_DIR/systemd/user/. This is similar to the | |
2281 | /run/systemd/user directory that was already previously | |
2282 | supported, but is under the control of the user. | |
2283 | ||
4ffd29fd LP |
2284 | * Job timeouts (i.e. time-outs on the time a job that is |
2285 | queued stays in the run queue) can now optionally result in | |
2286 | immediate reboot or power-off actions (JobTimeoutAction= and | |
2287 | JobTimeoutRebootArgument=). This is useful on ".target" | |
2288 | units, to limit the maximum time a target remains | |
2289 | undispatched in the run queue, and to trigger an emergency | |
2290 | operation in such a case. This is now used by default to | |
2291 | turn off the system if boot-up (as defined by everything in | |
2292 | basic.target) hangs and does not complete for at least | |
2293 | 15min. Also, if power-off or reboot hang for at least 30min | |
2294 | an immediate power-off/reboot operation is triggered. This | |
2295 | functionality is particularly useful to increase reliability | |
2296 | on embedded devices, but also on laptops which might | |
2297 | accidentally get powered on when carried in a backpack and | |
2298 | whose boot stays stuck in a hard disk encryption passphrase | |
2299 | question. | |
2300 | ||
b62a309a ZJS |
2301 | * systemd-logind can be configured to also handle lid switch |
2302 | events even when the machine is docked or multiple displays | |
2303 | are attached (HandleLidSwitchDocked= option). | |
2304 | ||
2305 | * A helper binary and a service have been added which can be | |
2306 | used to resume from hibernation in the initramfs. A | |
2307 | generator will parse the resume= option on the kernel | |
81c7dd89 | 2308 | command line to trigger resume. |
b62a309a | 2309 | |
78b6b7ce LP |
2310 | * A user console daemon systemd-consoled has been |
2311 | added. Currently, it is a preview, and will so far open a | |
2312 | single terminal on each session of the user marked as | |
09077149 | 2313 | Desktop=systemd-console. |
b62a309a ZJS |
2314 | |
2315 | * Route metrics can be specified for DHCP routes added by | |
2316 | systemd-networkd. | |
2317 | ||
ba8df74b | 2318 | * The SELinux context of socket-activated services can be set |
78b6b7ce | 2319 | from the information provided by the networking stack |
b62a309a ZJS |
2320 | (SELinuxContextFromNet= option). |
2321 | ||
2322 | * Userspace firmware loading support has been removed and | |
2323 | the minimum supported kernel version is thus bumped to 3.7. | |
2324 | ||
2325 | * Timeout for udev workers has been increased from 1 to 3 | |
2326 | minutes, but a warning will be printed after 1 minute to | |
2327 | help diagnose kernel modules that take a long time to load. | |
2328 | ||
78b6b7ce | 2329 | * Udev rules can now remove tags on devices with TAG-="foobar". |
b62a309a | 2330 | |
4bdc60cb | 2331 | * systemd's readahead implementation has been removed. In many |
f6d1de85 | 2332 | circumstances it didn't give expected benefits even for |
b62a309a | 2333 | rotational disk drives and was becoming less relevant in the |
78b6b7ce LP |
2334 | age of SSDs. As none of the developers has been using |
2335 | rotating media anymore, and nobody stepped up to actively | |
2336 | maintain this component of systemd it has now been removed. | |
b62a309a | 2337 | |
c4ac9900 | 2338 | * Swap units can use Options= to specify discard options. |
b62a309a ZJS |
2339 | Discard options specified for swaps in /etc/fstab are now |
2340 | respected. | |
2341 | ||
2342 | * Docker containers are now detected as a separate type of | |
2343 | virtualization. | |
2344 | ||
2345 | * The Password Agent protocol gained support for queries where | |
ba8df74b | 2346 | the user input is shown, useful e.g. for user names. |
78b6b7ce LP |
2347 | systemd-ask-password gained a new --echo option to turn that |
2348 | on. | |
b62a309a | 2349 | |
e6c253e3 MS |
2350 | * The default sysctl.d/ snippets will now set: |
2351 | ||
2352 | net.core.default_qdisc = fq_codel | |
2353 | ||
ba8df74b KS |
2354 | This selects Fair Queuing Controlled Delay as the default |
2355 | queuing discipline for network interfaces. fq_codel helps | |
e6c253e3 MS |
2356 | fight the network bufferbloat problem. It is believed to be |
2357 | a good default with no tuning required for most workloads. | |
2358 | Downstream distributions may override this choice. On 10Gbit | |
2359 | servers that do not do forwarding, "fq" may perform better. | |
2360 | Systems without a good clocksource should use "pfifo_fast". | |
2361 | ||
4bdc60cb LP |
2362 | * If kdbus is enabled during build a new option BusPolicy= is |
2363 | available for service units, that allows locking all service | |
2364 | processes into a stricter bus policy, in order to limit | |
2365 | access to various bus services, or even hide most of them | |
2366 | from the service's view entirely. | |
2367 | ||
2368 | * networkctl will now show the .network and .link file | |
2369 | networkd has applied to a specific interface. | |
2370 | ||
2371 | * sd-login gained a new API call sd_session_get_desktop() to | |
2372 | query which desktop environment has been selected for a | |
2373 | session. | |
2374 | ||
2375 | * UNIX utmp support is now compile-time optional to support | |
2376 | legacy-free systems. | |
2377 | ||
78b6b7ce LP |
2378 | * systemctl gained two new commands "add-wants" and |
2379 | "add-requires" for pulling in units from specific targets | |
2380 | easily. | |
2381 | ||
2382 | * If the word "rescue" is specified on the kernel command line | |
2383 | the system will now boot into rescue mode (aka | |
2384 | rescue.target), which was previously available only by | |
2385 | specifying "1" or "systemd.unit=rescue.target" on the kernel | |
2386 | command line. This new kernel command line option nicely | |
2387 | mirrors the already existing "emergency" kernel command line | |
2388 | option. | |
2389 | ||
2390 | * New kernel command line options mount.usr=, mount.usrflags=, | |
d4474c41 | 2391 | mount.usrfstype= have been added that match root=, rootflags=, |
78b6b7ce LP |
2392 | rootfstype= but allow mounting a specific file system to |
2393 | /usr. | |
2394 | ||
f6d1de85 | 2395 | * The $NOTIFY_SOCKET is now also passed to control processes of |
78b6b7ce LP |
2396 | services, not only the main process. |
2397 | ||
2398 | * This version reenables support for fsck's -l switch. This | |
2399 | means at least version v2.25 of util-linux is required for | |
2400 | operation, otherwise dead-locks on device nodes may | |
2401 | occur. Again: you need to update util-linux to at least | |
2402 | v2.25 when updating systemd to v217. | |
2403 | ||
3769415e TT |
2404 | * The "multi-seat-x" tool has been removed from systemd, as |
2405 | its functionality has been integrated into X servers 1.16, | |
2406 | and the tool is hence redundant. It is recommended to update | |
2407 | display managers invoking this tool to simply invoke X | |
2408 | directly from now on, again. | |
2409 | ||
fae9332b LP |
2410 | * Support for the new ALLOW_INTERACTIVE_AUTHORIZATION D-Bus |
2411 | message flag has been added for all of systemd's PolicyKit | |
2412 | authenticated method calls has been added. In particular | |
2413 | this now allows optional interactive authorization via | |
ba8df74b | 2414 | PolicyKit for many of PID1's privileged operations such as |
fae9332b LP |
2415 | unit file enabling and disabling. |
2416 | ||
cfa1571b LP |
2417 | * "udevadm hwdb --update" learnt a new switch "--usr" for |
2418 | placing the rebuilt hardware database in /usr instead of | |
2419 | /etc. When used only hardware database entries stored in | |
2420 | /usr will be used, and any user database entries in /etc are | |
2421 | ignored. This functionality is useful for vendors to ship a | |
2422 | pre-built database on systems where local configuration is | |
2423 | unnecessary or unlikely. | |
2424 | ||
7e63dd10 LP |
2425 | * Calendar time specifications in .timer units now also |
2426 | understand the strings "semi-annually", "quarterly" and | |
ba8df74b | 2427 | "minutely" as shortcuts (in addition to the preexisting |
7e63dd10 LP |
2428 | "anually", "hourly", ...). |
2429 | ||
d4474c41 TG |
2430 | * systemd-tmpfiles will now correctly create files in /dev |
2431 | at boot which are marked for creation only at boot. It is | |
2432 | recommended to always create static device nodes with 'c!' | |
2433 | and 'b!', so that they are created only at boot and not | |
2434 | overwritten at runtime. | |
2435 | ||
3b187c5c LP |
2436 | * When the watchdog logic is used for a service (WatchdogSec=) |
2437 | and the watchdog timeout is hit the service will now be | |
2438 | terminated with SIGABRT (instead of just SIGTERM), in order | |
2439 | to make sure a proper coredump and backtrace is | |
2440 | generated. This ensures that hanging services will result in | |
2441 | similar coredump/backtrace behaviour as services that hit a | |
2442 | segmentation fault. | |

b72ddf0f | 2469 | CHANGES WITH 216: |
b2ca0d63 LP |
2470 | |
2471 | * timedated no longer reads NTP implementation unit names from | |
b72ddf0f | 2472 | /usr/lib/systemd/ntp-units.d/*.list. Alternative NTP |
b2ca0d63 LP |
2473 | implementations should add a |
2474 | ||
b72ddf0f | 2475 | Conflicts=systemd-timesyncd.service |
b2ca0d63 LP |
2476 | |
2477 | to their unit files to take over and replace systemd's NTP | |
2478 | default functionality. | |
2479 | ||
2480 | * systemd-sysusers gained a new line type "r" for configuring | |
2481 | which UID/GID ranges to allocate system users/groups | |
2482 | from. Lines of type "u" may now add an additional column | |
2483 | that specifies the home directory for the system user to be | |
2484 | created. Also, systemd-sysusers may now optionally read user | |
2485 | information from STDIN instead of a file. This is useful for | |
2486 | invoking it from RPM preinst scriptlets that need to create | |
2487 | users before the first RPM file is installed since these | |
2488 | files might need to be owned by them. A new | |
2489 | %sysusers_create_inline RPM macro has been introduced to do | |
2490 | just that. systemd-sysusers now updates the shadow files as | |
2491 | well as the user/group databases, which should enhance | |
2492 | compatibility with certain tools like grpck. | |
2493 | ||
2494 | * A number of bus APIs of PID 1 now optionally consult | |
5f02e26c | 2495 | PolicyKit to permit access for otherwise unprivileged |
b2ca0d63 LP |
2496 | clients under certain conditions. Note that this currently |
2497 | doesn't support interactive authentication yet, but this is | |
2498 | expected to be added eventually, too. | |
2499 | ||
2500 | * /etc/machine-info now has new fields for configuring the | |
2501 | deployment environment of the machine, as well as the | |
2502 | location of the machine. hostnamectl has been updated with | |
2503 | new command to update these fields. | |
2504 | ||
2505 | * systemd-timesyncd has been updated to automatically acquire | |
2506 | NTP server information from systemd-networkd, which might | |
2507 | have been discovered via DHCP. | |
2508 | ||
2509 | * systemd-resolved now includes a caching DNS stub resolver | |
2510 | and a complete LLMNR name resolution implementation. A new | |
daa05349 AB |
2511 | NSS module "nss-resolve" has been added which can be used |
2512 | instead of glibc's own "nss-dns" to resolve hostnames via | |
b2ca0d63 LP |
2513 | systemd-resolved. Hostnames, addresses and arbitrary RRs may |
2514 | be resolved via systemd-resolved D-Bus APIs. In contrast to | |
2515 | the glibc internal resolver systemd-resolved is aware of | |
2516 | multi-homed system, and keeps DNS server and caches separate | |
5f02e26c | 2517 | and per-interface. Queries are sent simultaneously on all |
b2ca0d63 LP |
2518 | interfaces that have DNS servers configured, in order to |
2519 | properly handle VPNs and local LANs which might resolve | |
2520 | separate sets of domain names. systemd-resolved may acquire | |
a1a4a25e | 2521 | DNS server information from systemd-networkd automatically, |
b2ca0d63 LP |
2522 | which in turn might have discovered them via DHCP. A tool |
2523 | "systemd-resolve-host" has been added that may be used to | |
2524 | query the DNS logic in resolved. systemd-resolved implements | |
2525 | IDNA and automatically uses IDNA or UTF-8 encoding depending | |
2526 | on whether classic DNS or LLMNR is used as transport. In the | |
2527 | next releases we intend to add a DNSSEC and mDNS/DNS-SD | |
2528 | implementation to systemd-resolved. | |
2529 | ||
2530 | * A new NSS module nss-mymachines has been added, that | |
2531 | automatically resolves the names of all local registered | |
2532 | containers to their respective IP addresses. | |
2533 | ||
2534 | * A new client tool "networkctl" for systemd-networkd has been | |
2535 | added. It currently is entirely passive and will query | |
2536 | networking configuration from udev, rtnetlink and networkd, | |
5f02e26c | 2537 | and present it to the user in a very friendly |
b2ca0d63 LP |
2538 | way. Eventually, we hope to extend it to become a full |
2539 | control utility for networkd. | |
2540 | ||
2541 | * .socket units gained a new DeferAcceptSec= setting that | |
2542 | controls the kernels' TCP_DEFER_ACCEPT sockopt for | |
a8eaaee7 | 2543 | TCP. Similarly, support for controlling TCP keep-alive |
b2ca0d63 LP |
2544 | settings has been added (KeepAliveTimeSec=, |
2545 | KeepAliveIntervalSec=, KeepAliveProbes=). Also, support for | |
2546 | turning off Nagle's algorithm on TCP has been added | |
2547 | (NoDelay=). | |
2548 | ||
a1a4a25e | 2549 | * logind learned a new session type "web", for use in projects |
b2ca0d63 LP |
2550 | like Cockpit which register web clients as PAM sessions. |
2551 | ||
2552 | * timer units with at least one OnCalendar= setting will now | |
2553 | be started only after timer-sync.target has been | |
2554 | reached. This way they will not elapse before the system | |
2555 | clock has been corrected by a local NTP client or | |
2556 | similar. This is particular useful on RTC-less embedded | |
2557 | machines, that come up with an invalid system clock. | |
2558 | ||
2559 | * systemd-nspawn's --network-veth= switch should now result in | |
2560 | stable MAC addresses for both the outer and the inner side | |
2561 | of the link. | |
2562 | ||
2563 | * systemd-nspawn gained a new --volatile= switch for running | |
2564 | container instances with /etc or /var unpopulated. | |
2565 | ||
2566 | * The kdbus client code has been updated to use the new Linux | |
2567 | 3.17 memfd subsystem instead of the old kdbus-specific one. | |
2568 | ||
2569 | * systemd-networkd's DHCP client and server now support | |
01da80b1 LP |
2570 | FORCERENEW. There are also new configuration options to |
2571 | configure the vendor client identifier and broadcast mode | |
2572 | for DHCP. | |
b2ca0d63 LP |
2573 | |
2574 | * systemd will no longer inform the kernel about the current | |
2575 | timezone, as this is necessarily incorrect and racy as the | |
2576 | kernel has no understanding of DST and similar | |
2577 | concepts. This hence means FAT timestamps will be always | |
2578 | considered UTC, similar to what Android is already | |
2579 | doing. Also, when the RTC is configured to the local time | |
2580 | (rather than UTC) systemd will never synchronize back to it, | |
2581 | as this might confuse Windows at a later boot. | |
2582 | ||
2583 | * systemd-analyze gained a new command "verify" for offline | |
2584 | validation of unit files. | |
2585 | ||
2586 | * systemd-networkd gained support for a couple of additional | |
2587 | settings for bonding networking setups. Also, the metric for | |
2588 | statically configured routes may now be configured. For | |
2589 | network interfaces where this is appropriate the peer IP | |
2590 | address may now be configured. | |
2591 | ||
26568403 TG |
2592 | * systemd-networkd's DHCP client will no longer request |
2593 | broadcasting by default, as this tripped up some networks. | |
2594 | For hardware where broadcast is required the feature should | |
2595 | be switched back on using RequestBroadcast=yes. | |
2596 | ||
2597 | * systemd-networkd will now set up IPv4LL addresses (when | |
2598 | enabled) even if DHCP is configured successfully. | |
2599 | ||
2600 | * udev will now default to respect network device names given | |
2601 | by the kernel when the kernel indicates that these are | |
2602 | predictable. This behavior can be tweaked by changing | |
2603 | NamePolicy= in the relevant .link file. | |
2604 | ||
b2ca0d63 LP |
2605 | * A new library systemd-terminal has been added that |
2606 | implements full TTY stream parsing and rendering. This | |
2607 | library is supposed to be used later on for implementing a | |
2608 | full userspace VT subsystem, replacing the current kernel | |
2609 | implementation. | |
2610 | ||
2611 | * A new tool systemd-journal-upload has been added to push | |
2612 | journal data to a remote system running | |
2613 | systemd-journal-remote. | |
2614 | ||
2615 | * journald will no longer forward all local data to another | |
2616 | running syslog daemon. This change has been made because | |
2617 | rsyslog (which appears to be the most commonly used syslog | |
2618 | implementation these days) no longer makes use of this, and | |
2619 | instead pulls the data out of the journal on its own. Since | |
5f02e26c | 2620 | forwarding the messages to a non-existent syslog server is |
b2ca0d63 LP |
2621 | more expensive than we assumed we have now turned this |
2622 | off. If you run a syslog server that is not a recent rsyslog | |
2623 | version, you have to turn this option on again | |
2624 | (ForwardToSyslog= in journald.conf). | |
2625 | ||
2626 | * journald now optionally supports the LZ4 compressor for | |
2627 | larger journal fields. This compressor should perform much | |
2628 | better than XZ which was the previous default. | |
2629 | ||
2630 | * machinectl now shows the IP addresses of local containers, | |
2631 | if it knows them, plus the interface name of the container. | |
2632 | ||
2633 | * A new tool "systemd-escape" has been added that makes it | |
2634 | easy to escape strings to build unit names and similar. | |
2635 | ||
2636 | * sd_notify() messages may now include a new ERRNO= field | |
2637 | which is parsed and collected by systemd and shown among the | |
2638 | "systemctl status" output for a service. | |
2639 | ||
2640 | * A new component "systemd-firstboot" has been added that | |
2641 | queries the most basic systemd information (timezone, | |
a1a4a25e | 2642 | hostname, root password) interactively on first |
b2ca0d63 LP |
2643 | boot. Alternatively it may also be used to provision these |
2644 | things offline on OS images installed into directories. | |
2645 | ||
01da80b1 LP |
2646 | * The default sysctl.d/ snippets will now set |
2647 | ||
2648 | net.ipv4.conf.default.promote_secondaries=1 | |
2649 | ||
2650 | This has the benefit of no flushing secondary IP addresses | |
2651 | when primary addresses are removed. | |

3dff3e00 | 2671 | CHANGES WITH 215: |
24a2bf4c LP |
2672 | |
2673 | * A new tool systemd-sysusers has been added. This tool | |
2674 | creates system users and groups in /etc/passwd and | |
2675 | /etc/group, based on static declarative system user/group | |
2676 | definitions in /usr/lib/sysusers.d/. This is useful to | |
2677 | enable factory resets and volatile systems that boot up with | |
2678 | an empty /etc directory, and thus need system users and | |
2679 | groups created during early boot. systemd now also ships | |
2680 | with two default sysusers.d/ files for the most basic | |
2681 | users and groups systemd and the core operating system | |
2682 | require. | |
2683 | ||
2684 | * A new tmpfiles snippet has been added that rebuilds the | |
2685 | essential files in /etc on boot, should they be missing. | |
2686 | ||
2687 | * A directive for ensuring automatic clean-up of | |
2688 | /var/cache/man/ has been removed from the default | |
2689 | configuration. This line should now be shipped by the man | |
2690 | implementation. The necessary change has been made to the | |
2691 | man-db implementation. Note that you need to update your man | |
2692 | implementation to one that ships this line, otherwise no | |
2693 | automatic clean-up of /var/cache/man will take place. | |
2694 | ||
2695 | * A new condition ConditionNeedsUpdate= has been added that | |
2696 | may conditionalize services to only run when /etc or /var | |
2697 | are "older" than the vendor operating system resources in | |
2698 | /usr. This is useful for reconstructing or updating /etc | |
2699 | after an offline update of /usr or a factory reset, on the | |
2700 | next reboot. Services that want to run once after such an | |
2701 | update or reset should use this condition and order | |
2702 | themselves before the new systemd-update-done.service, which | |
2703 | will mark the two directories as fully updated. A number of | |
2704 | service files have been added making use of this, to rebuild | |
2705 | the udev hardware database, the journald message catalog and | |
2706 | dynamic loader cache (ldconfig). The systemd-sysusers tool | |
2707 | described above also makes use of this now. With this in | |
2708 | place it is now possible to start up a minimal operating | |
ce1dde29 | 2709 | system with /etc empty cleanly. For more information on the |
24a2bf4c LP |
2710 | concepts involved see this recent blog story: |
2711 | ||
2712 | http://0pointer.de/blog/projects/stateless.html | |
2713 | ||
2714 | * A new system group "input" has been introduced, and all | |
2715 | input device nodes get this group assigned. This is useful | |
2716 | for system-level software to get access to input devices. It | |
3dff3e00 KS |
2717 | complements what is already done for "audio" and "video". |
2718 | ||
24a2bf4c LP |
2719 | * systemd-networkd learnt minimal DHCPv4 server support in |
2720 | addition to the existing DHCPv4 client support. It also | |
2721 | learnt DHCPv6 client and IPv6 Router Solicitation client | |
2722 | support. The DHCPv4 client gained support for static routes | |
2723 | passed in from the server. Note that the [DHCPv4] section | |
2724 | known in older systemd-networkd versions has been renamed to | |
2725 | [DHCP] and is now also used by the DHCPv6 client. Existing | |
c7435cc9 LP |
2726 | .network files using settings of this section should be |
2727 | updated, though compatibility is maintained. Optionally, the | |
2728 | client hostname may now be sent to the DHCP server. | |
24a2bf4c | 2729 | |
c7435cc9 LP |
2730 | * networkd gained support for vxlan virtual networks as well |
2731 | as tun/tap and dummy devices. | |
24a2bf4c LP |
2732 | |
2733 | * networkd gained support for automatic allocation of address | |
2734 | ranges for interfaces from a system-wide pool of | |
2735 | addresses. This is useful for dynamically managing a large | |
2736 | number of interfaces with a single network configuration | |
2737 | file. In particular this is useful to easily assign | |
2738 | appropriate IP addresses to the veth links of a large number | |
2739 | of nspawn instances. | |
2740 | ||
2741 | * RPM macros for processing sysusers, sysctl and binfmt | |
2742 | drop-in snippets at package installation time have been | |
2743 | added. | |
2744 | ||
2745 | * The /etc/os-release file should now be placed in | |
2746 | /usr/lib/os-release. The old location is automatically | |
2747 | created as symlink. /usr/lib is the more appropriate | |
2748 | location of this file, since it shall actually describe the | |
2749 | vendor operating system shipped in /usr, and not the | |
2750 | configuration stored in /etc. | |
2751 | ||
2752 | * .mount units gained a new boolean SloppyOptions= setting | |
2753 | that maps to mount(8)'s -s option which enables permissive | |
2754 | parsing of unknown mount options. | |
2755 | ||
2756 | * tmpfiles learnt a new "L+" directive which creates a symlink | |
2757 | but (unlike "L") deletes a pre-existing file first, should | |
2758 | it already exist and not already be the correct | |
a8eaaee7 | 2759 | symlink. Similarly, "b+", "c+" and "p+" directives have been |
24a2bf4c LP |
2760 | added as well, which create block and character devices, as |
2761 | well as fifos in the filesystem, possibly removing any | |
2762 | pre-existing files of different types. | |
2763 | ||
2764 | * For tmpfiles' "L", "L+", "C" and "C+" directives the final | |
2765 | 'argument' field (which so far specified the source to | |
ce1dde29 | 2766 | symlink/copy the files from) is now optional. If omitted the |
24a2bf4c LP |
2767 | same file os copied from /usr/share/factory/ suffixed by the |
2768 | full destination path. This is useful for populating /etc | |
2769 | with essential files, by copying them from vendor defaults | |
2770 | shipped in /usr/share/factory/etc. | |
2771 | ||
2772 | * A new command "systemctl preset-all" has been added that | |
2773 | applies the service preset settings to all installed unit | |
2774 | files. A new switch --preset-mode= has been added that | |
2775 | controls whether only enable or only disable operations | |
2776 | shall be executed. | |
2777 | ||
2778 | * A new command "systemctl is-system-running" has been added | |
2779 | that allows checking the overall state of the system, for | |
ce1dde29 | 2780 | example whether it is fully up and running. |
24a2bf4c LP |
2781 | |
2782 | * When the system boots up with an empty /etc, the equivalent | |
2783 | to "systemctl preset-all" is executed during early boot, to | |
2784 | make sure all default services are enabled after a factory | |
2785 | reset. | |
2786 | ||
2787 | * systemd now contains a minimal preset file that enables the | |
2788 | most basic services systemd ships by default. | |
2789 | ||
2790 | * Unit files' [Install] section gained a new DefaultInstance= | |
2791 | field for defining the default instance to create if a | |
2792 | template unit is enabled with no instance specified. | |
2793 | ||
2794 | * A new passive target cryptsetup-pre.target has been added | |
2795 | that may be used by services that need to make they run and | |
2796 | finish before the first LUKS cryptographic device is set up. | |
2797 | ||
2798 | * The /dev/loop-control and /dev/btrfs-control device nodes | |
2799 | are now owned by the "disk" group by default, opening up | |
2800 | access to this group. | |
2801 | ||
2802 | * systemd-coredump will now automatically generate a | |
2803 | stack trace of all core dumps taking place on the system, | |
2804 | based on elfutils' libdw library. This stack trace is logged | |
2805 | to the journal. | |
2806 | ||
2807 | * systemd-coredump may now optionally store coredumps directly | |
2808 | on disk (in /var/lib/systemd/coredump, possibly compressed), | |
2809 | instead of storing them unconditionally in the journal. This | |
2810 | mode is the new default. A new configuration file | |
2811 | /etc/systemd/coredump.conf has been added to configure this | |
2812 | and other parameters of systemd-coredump. | |
2813 | ||
2814 | * coredumpctl gained a new "info" verb to show details about a | |
2815 | specific coredump. A new switch "-1" has also been added | |
2816 | that makes sure to only show information about the most | |
2817 | recent entry instead of all entries. Also, as the tool is | |
2818 | generally useful now the "systemd-" prefix of the binary | |
2819 | name has been removed. Distributions that want to maintain | |
2820 | compatibility with the old name should add a symlink from | |
2821 | the old name to the new name. | |
2822 | ||
2823 | * journald's SplitMode= now defaults to "uid". This makes sure | |
ce1dde29 | 2824 | that unprivileged users can access their own coredumps with |
24a2bf4c LP |
2825 | coredumpctl without restrictions. |
2826 | ||
2827 | * New kernel command line options "systemd.wants=" (for | |
2828 | pulling an additional unit during boot), "systemd.mask=" | |
2829 | (for masking a specific unit for the boot), and | |
2830 | "systemd.debug-shell" (for enabling the debug shell on tty9) | |
2831 | have been added. This is implemented in the new generator | |
2832 | "systemd-debug-generator". | |
2833 | ||
2834 | * systemd-nspawn will now by default filter a couple of | |
2835 | syscalls for containers, among them those required for | |
2836 | kernel module loading, direct x86 IO port access, swap | |
2837 | management, and kexec. Most importantly though | |
2838 | open_by_handle_at() is now prohibited for containers, | |
2839 | closing a hole similar to a recently discussed vulnerability | |
2840 | in docker regarding access to files on file hierarchies the | |
b938cb90 JE |
2841 | container should normally not have access to. Note that, for |
2842 | nspawn, we generally make no security claims anyway (and | |
24a2bf4c LP |
2843 | this is explicitly documented in the man page), so this is |
2844 | just a fix for one of the most obvious problems. | |
2845 | ||
2846 | * A new man page file-hierarchy(7) has been added that | |
2847 | contains a minimized, modernized version of the file system | |
2848 | layout systemd expects, similar in style to the FHS | |
c7435cc9 LP |
2849 | specification or hier(5). A new tool systemd-path(1) has |
2850 | been added to query many of these paths for the local | |
2851 | machine and user. | |
24a2bf4c LP |
2852 | |
2853 | * Automatic time-based clean-up of $XDG_RUNTIME_DIR is no | |
2854 | longer done. Since the directory now has a per-user size | |
2855 | limit, and is cleaned on logout this appears unnecessary, | |
2856 | in particular since this now brings the lifecycle of this | |
2857 | directory closer in line with how IPC objects are handled. | |
2858 | ||
2859 | * systemd.pc now exports a number of additional directories, | |
2860 | including $libdir (which is useful to identify the library | |
2861 | path for the primary architecture of the system), and a | |
2862 | couple of drop-in directories. | |
2863 | ||
3058e017 TLSC |
2864 | * udev's predictable network interface names now use the dev_port |
2865 | sysfs attribute, introduced in linux 3.15 instead of dev_id to | |
2866 | distinguish between ports of the same PCI function. dev_id should | |
2867 | only be used for ports using the same HW address, hence the need | |
2868 | for dev_port. | |
2869 | ||
c7435cc9 LP |
2870 | * machined has been updated to export the OS version of a |
2871 | container (read from /etc/os-release and | |
2872 | /usr/lib/os-release) on the bus. This is now shown in | |
2873 | "machinectl status" for a machine. | |
2874 | ||
2875 | * A new service setting RestartForceExitStatus= has been | |
2876 | added. If configured to a set of exit signals or process | |
2877 | return values, the service will be restarted when the main | |
2878 | daemon process exits with any of them, regardless of the | |
2879 | Restart= setting. | |
2880 | ||
2881 | * systemctl's -H switch for connecting to remote systemd | |
2882 | machines has been extended so that it may be used to | |
2883 | directly connect to a specific container on the | |
2884 | host. "systemctl -H root@foobar:waldi" will now connect as | |
2885 | user "root" to host "foobar", and then proceed directly to | |
2886 | the container named "waldi". Note that currently you have to | |
2887 | authenticate as user "root" for this to work, as entering | |
2888 | containers is a privileged operation. | |

c7435cc9 | 2904 | |
4196a3ea KS |
2905 | CHANGES WITH 214: |
2906 | ||
2907 | * As an experimental feature, udev now tries to lock the | |
2908 | disk device node (flock(LOCK_SH|LOCK_NB)) while it | |
2909 | executes events for the disk or any of its partitions. | |
2910 | Applications like partitioning programs can lock the | |
2911 | disk device node (flock(LOCK_EX)) and claim temporary | |
2912 | device ownership that way; udev will entirely skip all event | |
2913 | handling for this disk and its partitions. If the disk | |
2914 | was opened for writing, the close will trigger a partition | |
2915 | table rescan in udev's "watch" facility, and if needed | |
71449caf | 2916 | synthesize "change" events for the disk and all its partitions. |
8d0e0ddd | 2917 | This is now unconditionally enabled, and if it turns out to |
4196a3ea | 2918 | cause major problems, we might turn it on only for specific |
45df8656 | 2919 | devices, or might need to disable it entirely. Device Mapper |
4196a3ea KS |
2920 | devices are excluded from this logic. |
2921 | ||
04e91da2 LP |
2922 | * We temporarily dropped the "-l" switch for fsck invocations, |
2923 | since they collide with the flock() logic above. util-linux | |
2924 | upstream has been changed already to avoid this conflict, | |
2925 | and we will readd "-l" as soon as util-linux with this | |
2926 | change has been released. | |
2927 | ||
2928 | * The dependency on libattr has been removed. Since a long | |
8d0e0ddd | 2929 | time, the extended attribute calls have moved to glibc, and |
04e91da2 LP |
2930 | libattr is thus unnecessary. |
2931 | ||
2932 | * Virtualization detection works without priviliges now. This | |
2933 | means the systemd-detect-virt binary no longer requires | |
2934 | CAP_SYS_PTRACE file capabilities, and our daemons can run | |
71449caf | 2935 | with fewer privileges. |
04e91da2 LP |
2936 | |
2937 | * systemd-networkd now runs under its own "systemd-network" | |
2938 | user. It retains the CAP_NET_ADMIN, CAP_NET_BIND_SERVICE, | |
2939 | CAP_NET_BROADCAST, CAP_NET_RAW capabilities though, but | |
2940 | loses the ability to write to files owned by root this way. | |
2941 | ||
a8eaaee7 | 2942 | * Similarly, systemd-resolved now runs under its own |
04e91da2 LP |
2943 | "systemd-resolve" user with no capabilities remaining. |
2944 | ||
a8eaaee7 | 2945 | * Similarly, systemd-bus-proxyd now runs under its own |
04e91da2 LP |
2946 | "systemd-bus-proxy" user with only CAP_IPC_OWNER remaining. |
2947 | ||
2948 | * systemd-networkd gained support for setting up "veth" | |
a8eaaee7 | 2949 | virtual Ethernet devices for container connectivity, as well |
04e91da2 LP |
2950 | as GRE and VTI tunnels. |
2951 | ||
2952 | * systemd-networkd will no longer automatically attempt to | |
2953 | manually load kernel modules necessary for certain tunnel | |
8d0e0ddd | 2954 | transports. Instead, it is assumed the kernel loads them |
04e91da2 LP |
2955 | automatically when required. This only works correctly on |
2956 | very new kernels. On older kernels, please consider adding | |
c54bed5d | 2957 | the kernel modules to /etc/modules-load.d/ as a work-around. |
04e91da2 | 2958 | |
cd14eda3 | 2959 | * The resolv.conf file systemd-resolved generates has been |
8d0e0ddd JE |
2960 | moved to /run/systemd/resolve/. If you have a symlink from |
2961 | /etc/resolv.conf, it might be necessary to correct it. | |
cd14eda3 | 2962 | |
ef392da6 | 2963 | * Two new service settings, ProtectHome= and ProtectSystem=, |
8d0e0ddd | 2964 | have been added. When enabled, they will make the user data |
04e91da2 LP |
2965 | (such as /home) inaccessible or read-only and the system |
2966 | (such as /usr) read-only, for specific services. This allows | |
2967 | very light-weight per-service sandboxing to avoid | |
2968 | modifications of user data or system files from | |
2969 | services. These two new switches have been enabled for all | |
2970 | of systemd's long-running services, where appropriate. | |
2971 | ||
2972 | * Socket units gained new SocketUser= and SocketGroup= | |
2973 | settings to set the owner user and group of AF_UNIX sockets | |
2974 | and FIFOs in the file system. | |
2975 | ||
8d0e0ddd | 2976 | * Socket units gained a new RemoveOnStop= setting. If enabled, |
04e91da2 LP |
2977 | all FIFOS and sockets in the file system will be removed |
2978 | when the specific socket unit is stopped. | |
2979 | ||
2980 | * Socket units gained a new Symlinks= setting. It takes a list | |
2981 | of symlinks to create to file system sockets or FIFOs | |
45df8656 | 2982 | created by the specific Unix sockets. This is useful to |
71449caf | 2983 | manage symlinks to socket nodes with the same life-cycle as |
04e91da2 LP |
2984 | the socket itself. |
2985 | ||
2986 | * The /dev/log socket and /dev/initctl FIFO have been moved to | |
2987 | /run, and have been replaced by symlinks. This allows | |
2988 | connecting to these facilities even if PrivateDevices=yes is | |
2989 | used for a service (which makes /dev/log itself unavailable, | |
2990 | but /run is left). This also has the benefit of ensuring | |
2991 | that /dev only contains device nodes, directories and | |
2992 | symlinks, and nothing else. | |
2993 | ||
2994 | * sd-daemon gained two new calls sd_pid_notify() and | |
2995 | sd_pid_notifyf(). They are similar to sd_notify() and | |
2996 | sd_notifyf(), but allow overriding of the source PID of | |
2997 | notification messages if permissions permit this. This is | |
2998 | useful to send notify messages on behalf of a different | |
2999 | process (for example, the parent process). The | |
3000 | systemd-notify tool has been updated to make use of this | |
3001 | when sending messages (so that notification messages now | |
3002 | originate from the shell script invoking systemd-notify and | |
3003 | not the systemd-notify process itself. This should minimize | |
3004 | a race where systemd fails to associate notification | |
3005 | messages to services when the originating process already | |
3006 | vanished. | |
3007 | ||
3008 | * A new "on-abnormal" setting for Restart= has been added. If | |
8d0e0ddd | 3009 | set, it will result in automatic restarts on all "abnormal" |
04e91da2 LP |
3010 | reasons for a process to exit, which includes unclean |
3011 | signals, core dumps, timeouts and watchdog timeouts, but | |
3012 | does not include clean and unclean exit codes or clean | |
3013 | signals. Restart=on-abnormal is an alternative for | |
3014 | Restart=on-failure for services that shall be able to | |
3015 | terminate and avoid restarts on certain errors, by | |
3016 | indicating so with an unclean exit code. Restart=on-failure | |
3017 | or Restart=on-abnormal is now the recommended setting for | |
3018 | all long-running services. | |
3019 | ||
3020 | * If the InaccessibleDirectories= service setting points to a | |
3021 | mount point (or if there are any submounts contained within | |
3022 | it), it is now attempted to completely unmount it, to make | |
3023 | the file systems truly unavailable for the respective | |
3024 | service. | |
3025 | ||
3026 | * The ReadOnlyDirectories= service setting and | |
3027 | systemd-nspawn's --read-only parameter are now recursively | |
3028 | applied to all submounts, too. | |
3029 | ||
3030 | * Mount units may now be created transiently via the bus APIs. | |
3031 | ||
3032 | * The support for SysV and LSB init scripts has been removed | |
3033 | from the systemd daemon itself. Instead, it is now | |
3034 | implemented as a generator that creates native systemd units | |
3035 | from these scripts when needed. This enables us to remove a | |
3036 | substantial amount of legacy code from PID 1, following the | |
3037 | fact that many distributions only ship a very small number | |
3038 | of LSB/SysV init scripts nowadays. | |
3039 | ||
cc98b302 | 3040 | * Privileged Xen (dom0) domains are not considered |
04e91da2 LP |
3041 | virtualization anymore by the virtualization detection |
3042 | logic. After all, they generally have unrestricted access to | |
71449caf | 3043 | the hardware and usually are used to manage the unprivileged |
04e91da2 LP |
3044 | (domU) domains. |
3045 | ||
3046 | * systemd-tmpfiles gained a new "C" line type, for copying | |
3047 | files or entire directories. | |
3048 | ||
3049 | * systemd-tmpfiles "m" lines are now fully equivalent to "z" | |
8d0e0ddd JE |
3050 | lines. So far, they have been non-globbing versions of the |
3051 | latter, and have thus been redundant. In future, it is | |
3052 | recommended to only use "z". "m" has hence been removed | |
04e91da2 LP |
3053 | from the documentation, even though it stays supported. |
3054 | ||
3055 | * A tmpfiles snippet to recreate the most basic structure in | |
3056 | /var has been added. This is enough to create the /var/run → | |
3057 | /run symlink and create a couple of structural | |
3058 | directories. This allows systems to boot up with an empty or | |
8d0e0ddd JE |
3059 | volatile /var. Of course, while with this change, the core OS |
3060 | now is capable with dealing with a volatile /var, not all | |
04e91da2 | 3061 | user services are ready for it. However, we hope that sooner |
8d0e0ddd | 3062 | or later, many service daemons will be changed upstream so |
04e91da2 LP |
3063 | that they are able to automatically create their necessary |
3064 | directories in /var at boot, should they be missing. This is | |
3065 | the first step to allow state-less systems that only require | |
3066 | the vendor image for /usr to boot. | |
3067 | ||
3068 | * systemd-nspawn has gained a new --tmpfs= switch to mount an | |
3069 | empty tmpfs instance to a specific directory. This is | |
3070 | particularly useful for making use of the automatic | |
3071 | reconstruction of /var (see above), by passing --tmpfs=/var. | |
3072 | ||
3073 | * Access modes specified in tmpfiles snippets may now be | |
3074 | prefixed with "~", which indicates that they shall be masked | |
daa05349 | 3075 | by whether the existing file or directory is currently |
8d0e0ddd | 3076 | writable, readable or executable at all. Also, if specified, |
04e91da2 LP |
3077 | the sgid/suid/sticky bits will be masked for all |
3078 | non-directories. | |
3079 | ||
3080 | * A new passive target unit "network-pre.target" has been | |
3081 | added which is useful for services that shall run before any | |
3082 | network is configured, for example firewall scripts. | |
3083 | ||
4c0d13bd LP |
3084 | * The "floppy" group that previously owned the /dev/fd* |
3085 | devices is no longer used. The "disk" group is now used | |
3086 | instead. Distributions should probably deprecate usage of | |
3087 | this group. | |

3099 | CHANGES WITH 213: |
3100 | ||
3101 | * A new "systemd-timesyncd" daemon has been added for | |
69beda1f | 3102 | synchronizing the system clock across the network. It |
6936cd89 | 3103 | implements an SNTP client. In contrast to NTP |
8d0e0ddd | 3104 | implementations such as chrony or the NTP reference server, |
6936cd89 | 3105 | this only implements a client side, and does not bother with |
c9679c65 LP |
3106 | the full NTP complexity, focusing only on querying time from |
3107 | one remote server and synchronizing the local clock to | |
6936cd89 | 3108 | it. Unless you intend to serve NTP to networked clients or |
8d0e0ddd | 3109 | want to connect to local hardware clocks, this simple NTP |
6936cd89 LP |
3110 | client should be more than appropriate for most |
3111 | installations. The daemon runs with minimal privileges, and | |
3112 | has been hooked up with networkd to only operate when | |
3113 | network connectivity is available. The daemon saves the | |
3114 | current clock to disk every time a new NTP sync has been | |
3115 | acquired, and uses this to possibly correct the system clock | |
69beda1f | 3116 | early at bootup, in order to accommodate for systems that |
6936cd89 | 3117 | lack an RTC such as the Raspberry Pi and embedded devices, |
8d0e0ddd | 3118 | and to make sure that time monotonically progresses on these |
c9679c65 | 3119 | systems, even if it is not always correct. To make use of |
8d0e0ddd | 3120 | this daemon, a new system user and group "systemd-timesync" |
c9679c65 | 3121 | needs to be created on installation of systemd. |
6936cd89 | 3122 | |
69beda1f KS |
3123 | * The queue "seqnum" interface of libudev has been disabled, as |
3124 | it was generally incompatible with device namespacing as | |
6936cd89 LP |
3125 | sequence numbers of devices go "missing" if the devices are |
3126 | part of a different namespace. | |
3127 | ||
3128 | * "systemctl list-timers" and "systemctl list-sockets" gained | |
3129 | a --recursive switch for showing units of these types also | |
499b604b ZJS |
3130 | for all local containers, similar in style to the already |
3131 | supported --recursive switch for "systemctl list-units". | |
6936cd89 LP |
3132 | |
3133 | * A new RebootArgument= setting has been added for service | |
3134 | units, which may be used to specify a kernel reboot argument | |
499b604b | 3135 | to use when triggering reboots with StartLimitAction=. |
6936cd89 LP |
3136 | |
3137 | * A new FailureAction= setting has been added for service | |
3138 | units which may be used to specify an operation to trigger | |
499b604b | 3139 | when a service fails. This works similarly to |
8d0e0ddd | 3140 | StartLimitAction=, but unlike it, controls what is done |
6936cd89 LP |
3141 | immediately rather than only after several attempts to |
3142 | restart the service in question. | |
3143 | ||
3144 | * hostnamed got updated to also expose the kernel name, | |
499b604b ZJS |
3145 | release, and version on the bus. This is useful for |
3146 | executing commands like hostnamectl with the -H switch. | |
3147 | systemd-analyze makes use of this to properly display | |
3148 | details when running non-locally. | |
6936cd89 LP |
3149 | |
3150 | * The bootchart tool can now show cgroup information in the | |
3151 | graphs it generates. | |
3152 | ||
3153 | * The CFS CPU quota cgroup attribute is now exposed for | |
3154 | services. The new CPUQuota= switch has been added for this | |
3155 | which takes a percentage value. Setting this will have the | |
3156 | result that a service may never get more CPU time than the | |
3157 | specified percentage, even if the machine is otherwise idle. | |
3158 | ||
3159 | * systemd-networkd learned IPIP and SIT tunnel support. | |
3160 | ||
3161 | * LSB init scripts exposing a dependency on $network will now | |
3162 | get a dependency on network-online.target rather than simply | |
3163 | network.target. This should bring LSB handling closer to | |
3164 | what it was on SysV systems. | |
3165 | ||
3166 | * A new fsck.repair= kernel option has been added to control | |
3167 | how fsck shall deal with unclean file systems at boot. | |
3168 | ||
3169 | * The (.ini) configuration file parser will now silently | |
3170 | ignore sections whose name begins with "X-". This may be | |
3171 | used to maintain application-specific extension sections in unit | |
3172 | files. | |
3173 | ||
3174 | * machined gained a new API to query the IP addresses of | |
3175 | registered containers. "machinectl status" has been updated | |
3176 | to show these addresses in its output. | |
3177 | ||
3178 | * A new call sd_uid_get_display() has been added to the | |
3179 | sd-login APIs for querying the "primary" session of a | |
3180 | user. The "primary" session of the user is elected from the | |
3181 | user's sessions and generally a graphical session is | |
3182 | preferred over a text one. | |
3183 | ||
3184 | * A minimal systemd-resolved daemon has been added. It | |
3185 | currently simply acts as a companion to systemd-networkd and | |
3186 | manages resolv.conf based on per-interface DNS | |
3187 | configuration, possibly supplied via DHCP. In the long run | |
3188 | we hope to extend this into a local DNSSEC enabled DNS and | |
3189 | mDNS cache. | |
3190 | ||
68dd0956 TG |
3191 | * The systemd-networkd-wait-online tool is now enabled by |
3192 | default. It will delay network-online.target until a network | |
3193 | connection has been configured. The tool primarily integrates | |
3194 | with networkd, but will also make a best effort to make sense | |
3195 | of network configuration performed in some other way. | |
3196 | ||
6936cd89 | 3197 | * Two new service options StartupCPUShares= and |
499b604b | 3198 | StartupBlockIOWeight= have been added that work similarly to |
6936cd89 | 3199 | CPUShares= and BlockIOWeight= however only apply during |
69beda1f | 3200 | system startup. This is useful to prioritize certain services |
6936cd89 LP |
3201 | differently during bootup than during normal runtime. |
3202 | ||
8e7acf67 LP |
3203 | * hostnamed has been changed to prefer the statically |
3204 | configured hostname in /etc/hostname (unless set to | |
3205 | 'localhost' or empty) over any dynamic one supplied by | |
8d0e0ddd | 3206 | dhcp. With this change, the rules for picking the hostname |
8e7acf67 LP |
3207 | match more closely the rules of other configuration settings |
3208 | where the local administrator's configuration in /etc always | |
3209 | overrides any other settings. | |

3231 | CHANGES WITH 212: |
3232 | ||
3233 | * When restoring the screen brightness at boot, stay away from | |
3234 | the darkest setting or from the lowest 5% of the available | |
3235 | range, depending on which is the larger value of both. This | |
3236 | should effectively protect the user from rebooting into a | |
3237 | black screen, should the brightness have been set to minimum | |
3238 | by accident. | |
3239 | ||
3240 | * sd-login gained a new sd_machine_get_class() call to | |
3241 | determine the class ("vm" or "container") of a machine | |
3242 | registered with machined. | |
3243 | ||
3244 | * sd-login gained new calls | |
3245 | sd_peer_get_{session,owner_uid,unit,user_unit,slice,machine_name}(), | |
3246 | to query the identity of the peer of a local AF_UNIX | |
499b604b | 3247 | connection. They operate similarly to their sd_pid_get_xyz() |
51c61cda LP |
3248 | counterparts. |
3249 | ||
3250 | * PID 1 will now maintain a system-wide system state engine | |
3251 | with the states "starting", "running", "degraded", | |
3252 | "maintenance", "stopping". These states are bound to system | |
3253 | startup, normal runtime, runtime with at least one failed | |
3254 | service, rescue/emergency mode and system shutdown. This | |
3255 | state is shown in the "systemctl status" output when no unit | |
3256 | name is passed. It is useful to determine system state, in | |
3257 | particularly when doing so for many systems or containers at | |
3258 | once. | |
3259 | ||
3260 | * A new command "list-machines" has been added to "systemctl" | |
3261 | that lists all local OS containers and shows their system | |
3262 | state (see above), if systemd runs inside of them. | |
3263 | ||
3264 | * systemctl gained a new "-r" switch to recursively enumerate | |
3265 | units on all local containers, when used with the | |
3266 | "list-unit" command (which is the default one that is | |
3267 | executed when no parameters are specified). | |
3268 | ||
3269 | * The GPT automatic partition discovery logic will now honour | |
3270 | two GPT partition flags: one may be set on a partition to | |
3271 | cause it to be mounted read-only, and the other may be set | |
3272 | on a partition to ignore it during automatic discovery. | |
3273 | ||
3274 | * Two new GPT type UUIDs have been added for automatic root | |
70a44afe | 3275 | partition discovery, for 32-bit and 64-bit ARM. This is not |
51c61cda LP |
3276 | particularly useful for discovering the root directory on |
3277 | these architectures during bare-metal boots (since UEFI is | |
3278 | not common there), but still very useful to allow booting of | |
3279 | ARM disk images in nspawn with the -i option. | |
3280 | ||
3281 | * MAC addresses of interfaces created with nspawn's | |
3282 | --network-interface= switch will now be generated from the | |
3283 | machine name, and thus be stable between multiple invocations | |
3284 | of the container. | |
3285 | ||
3286 | * logind will now automatically remove all IPC objects owned | |
3287 | by a user if she or he fully logs out. This makes sure that | |
3288 | users who are logged out cannot continue to consume IPC | |
3289 | resources. This covers SysV memory, semaphores and message | |
3290 | queues as well as POSIX shared memory and message | |
b8bde116 JE |
3291 | queues. Traditionally, SysV and POSIX IPC had no life-cycle |
3292 | limits. With this functionality, that is corrected. This may | |
3293 | be turned off by using the RemoveIPC= switch of logind.conf. | |
51c61cda LP |
3294 | |
3295 | * The systemd-machine-id-setup and tmpfiles tools gained a | |
3296 | --root= switch to operate on a specific root directory, | |
3297 | instead of /. | |
3298 | ||
3299 | * journald can now forward logged messages to the TTYs of all | |
3300 | logged in users ("wall"). This is the default for all | |
3301 | emergency messages now. | |
3302 | ||
3303 | * A new tool systemd-journal-remote has been added to stream | |
3304 | journal log messages across the network. | |
3305 | ||
3306 | * /sys/fs/cgroup/ is now mounted read-only after all cgroup | |
3307 | controller trees are mounted into it. Note that the | |
3308 | directories mounted beneath it are not read-only. This is a | |
3309 | security measure and is particularly useful because glibc | |
3310 | actually includes a search logic to pick any tmpfs it can | |
3311 | find to implement shm_open() if /dev/shm is not available | |
3312 | (which it might very well be in namespaced setups). | |
3313 | ||
3314 | * machinectl gained a new "poweroff" command to cleanly power | |
3315 | down a local OS container. | |
3316 | ||
3317 | * The PrivateDevices= unit file setting will now also drop the | |
3318 | CAP_MKNOD capability from the capability bound set, and | |
3319 | imply DevicePolicy=closed. | |
3320 | ||
3321 | * PrivateDevices=, PrivateNetwork= and PrivateTmp= is now used | |
3322 | comprehensively on all long-running systemd services where | |
3323 | this is appropriate. | |
3324 | ||
3325 | * systemd-udevd will now run in a disassociated mount | |
b8bde116 | 3326 | namespace. To mount directories from udev rules, make sure to |
51c61cda LP |
3327 | pull in mount units via SYSTEMD_WANTS properties. |
3328 | ||
3329 | * The kdbus support gained support for uploading policy into | |
3330 | the kernel. sd-bus gained support for creating "monitoring" | |
3331 | connections that can eavesdrop into all bus communication | |
3332 | for debugging purposes. | |
3333 | ||
3334 | * Timestamps may now be specified in seconds since the UNIX | |
3335 | epoch Jan 1st, 1970 by specifying "@" followed by the value | |
3336 | in seconds. | |
3337 | ||
3338 | * Native tcpwrap support in systemd has been removed. tcpwrap | |
3339 | is old code, not really maintained anymore and has serious | |
3340 | shortcomings, and better options such as firewalls | |
3341 | exist. For setups that require tcpwrap usage, please | |
3342 | consider invoking your socket-activated service via tcpd, | |
3343 | like on traditional inetd. | |
3344 | ||
3345 | * A new system.conf configuration option | |
3346 | DefaultTimerAccuracySec= has been added that controls the | |
3347 | default AccuracySec= setting of .timer units. | |
3348 | ||
b8bde116 | 3349 | * Timer units gained a new WakeSystem= switch. If enabled, |
51c61cda LP |
3350 | timers configured this way will cause the system to resume |
3351 | from system suspend (if the system supports that, which most | |
3352 | do these days). | |
3353 | ||
b8bde116 | 3354 | * Timer units gained a new Persistent= switch. If enabled, |
51c61cda LP |
3355 | timers configured this way will save to disk when they have |
3356 | been last triggered. This information is then used on next | |
3357 | reboot to possible execute overdue timer events, that | |
d28315e4 JE |
3358 | could not take place because the system was powered off. |
3359 | This enables simple anacron-like behaviour for timer units. | |
51c61cda LP |
3360 | |
3361 | * systemctl's "list-timers" will now also list the time a | |
3362 | timer unit was last triggered in addition to the next time | |
3363 | it will be triggered. | |
3364 | ||
3365 | * systemd-networkd will now assign predictable IPv4LL | |
3366 | addresses to its local interfaces. | |

3380 | CHANGES WITH 211: |
3381 | ||
3382 | * A new unit file setting RestrictAddressFamilies= has been | |
3383 | added to restrict which socket address families unit | |
3384 | processes gain access to. This takes address family names | |
3385 | like "AF_INET" or "AF_UNIX", and is useful to minimize the | |
3386 | attack surface of services via exotic protocol stacks. This | |
3387 | is built on seccomp system call filters. | |
3388 | ||
3389 | * Two new unit file settings RuntimeDirectory= and | |
3390 | RuntimeDirectoryMode= have been added that may be used to | |
3391 | manage a per-daemon runtime directories below /run. This is | |
3392 | an alternative for setting up directory permissions with | |
3393 | tmpfiles snippets, and has the advantage that the runtime | |
3394 | directory's lifetime is bound to the daemon runtime and that | |
3395 | the daemon starts up with an empty directory each time. This | |
3396 | is particularly useful when writing services that drop | |
f1721625 | 3397 | privileges using the User= or Group= setting. |
699b6b34 LP |
3398 | |
3399 | * The DeviceAllow= unit setting now supports globbing for | |
3400 | matching against device group names. | |
3401 | ||
3402 | * The systemd configuration file system.conf gained new | |
3403 | settings DefaultCPUAccounting=, DefaultBlockIOAccounting=, | |
3404 | DefaultMemoryAccounting= to globally turn on/off accounting | |
3405 | for specific resources (cgroups) for all units. These | |
22e7062d | 3406 | settings may still be overridden individually in each unit |
699b6b34 LP |
3407 | though. |
3408 | ||
3409 | * systemd-gpt-auto-generator is now able to discover /srv and | |
3410 | root partitions in addition to /home and swap partitions. It | |
3411 | also supports LUKS-encrypted partitions now. With this in | |
b8bde116 | 3412 | place, automatic discovery of partitions to mount following |
699b6b34 LP |
3413 | the Discoverable Partitions Specification |
3414 | (http://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec) | |
3415 | is now a lot more complete. This allows booting without | |
3416 | /etc/fstab and without root= on the kernel command line on | |
b8bde116 | 3417 | systems prepared appropriately. |
699b6b34 LP |
3418 | |
3419 | * systemd-nspawn gained a new --image= switch which allows | |
3420 | booting up disk images and Linux installations on any block | |
3421 | device that follow the Discoverable Partitions Specification | |
3422 | (see above). This means that installations made with | |
3423 | appropriately updated installers may now be started and | |
3424 | deployed using container managers, completely | |
3425 | unmodified. (We hope that libvirt-lxc will add support for | |
3426 | this feature soon, too.) | |
3427 | ||
3428 | * systemd-nspawn gained a new --network-macvlan= setting to | |
3429 | set up a private macvlan interface for the | |
499b604b | 3430 | container. Similarly, systemd-networkd gained a new |
699b6b34 LP |
3431 | Kind=macvlan setting in .netdev files. |
3432 | ||
3433 | * systemd-networkd now supports configuring local addresses | |
3434 | using IPv4LL. | |
3435 | ||
3436 | * A new tool systemd-network-wait-online has been added to | |
3437 | synchronously wait for network connectivity using | |
3438 | systemd-networkd. | |
3439 | ||
3440 | * The sd-bus.h bus API gained a new sd_bus_track object for | |
3441 | tracking the life-cycle of bus peers. Note that sd-bus.h is | |
3442 | still not a public API though (unless you specify | |
3443 | --enable-kdbus on the configure command line, which however | |
3444 | voids your warranty and you get no API stability guarantee). | |
3445 | ||
3446 | * The $XDG_RUNTIME_DIR runtime directories for each user are | |
3447 | now individual tmpfs instances, which has the benefit of | |
3448 | introducing separate pools for each user, with individual | |
4ef6e535 | 3449 | size limits, and thus making sure that unprivileged clients |
699b6b34 LP |
3450 | can no longer negatively impact the system or other users by |
3451 | filling up their $XDG_RUNTIME_DIR. A new logind.conf setting | |
3452 | RuntimeDirectorySize= has been introduced that allows | |
3453 | controlling the default size limit for all users. It | |
3454 | defaults to 10% of the available physical memory. This is no | |
3455 | replacement for quotas on tmpfs though (which the kernel | |
3456 | still does not support), as /dev/shm and /tmp are still | |
4ef6e535 | 3457 | shared resources used by both the system and unprivileged |
699b6b34 LP |
3458 | users. |
3459 | ||
3460 | * logind will now automatically turn off automatic suspending | |
3461 | on laptop lid close when more than one display is | |
3462 | connected. This was previously expected to be implemented | |
3463 | individually in desktop environments (such as GNOME), | |
3464 | however has been added to logind now, in order to fix a | |
3465 | boot-time race where a desktop environment might not have | |
3466 | been started yet and thus not been able to take an inhibitor | |
3467 | lock at the time where logind already suspends the system | |
3468 | due to a closed lid. | |
3469 | ||
3470 | * logind will now wait at least 30s after each system | |
3471 | suspend/resume cycle, and 3min after system boot before | |
3472 | suspending the system due to a closed laptop lid. This | |
3473 | should give USB docking stations and similar enough time to | |
4ef6e535 | 3474 | be probed and configured after system resume and boot in |
699b6b34 LP |
3475 | order to then act as suspend blocker. |
3476 | ||
3477 | * systemd-run gained a new --property= setting which allows | |
3478 | initialization of resource control properties (and others) | |
3479 | for the created scope or service unit. Example: "systemd-run | |
3480 | --property=BlockIOWeight=10 updatedb" may be used to run | |
3481 | updatedb at a low block IO scheduling weight. | |
3482 | ||
3483 | * systemd-run's --uid=, --gid=, --setenv=, --setenv= switches | |
3484 | now also work in --scope mode. | |
3485 | ||
3486 | * When systemd is compiled with kdbus support, basic support | |
3487 | for enforced policies is now in place. (Note that enabling | |
3488 | kdbus still voids your warranty and no API compatibility | |
3489 | promises are made.) | |

43c71255 LP |
3504 | CHANGES WITH 210: |
3505 | ||
3506 | * systemd will now relabel /dev after loading the SMACK policy | |
3507 | according to SMACK rules. | |
3508 | ||
67dd87c5 | 3509 | * A new unit file option AppArmorProfile= has been added to |
43c71255 LP |
3510 | set the AppArmor profile for the processes of a unit. |
3511 | ||
3512 | * A new condition check ConditionArchitecture= has been added | |
3513 | to conditionalize units based on the system architecture, as | |
3514 | reported by uname()'s "machine" field. | |
3515 | ||
3516 | * systemd-networkd now supports matching on the system | |
3517 | virtualization, architecture, kernel command line, host name | |
3518 | and machine ID. | |
3519 | ||
ed28905e | 3520 | * logind is now a lot more aggressive when suspending the |
43c71255 | 3521 | machine due to a closed laptop lid. Instead of acting only |
b8bde116 | 3522 | on the lid close action, it will continuously watch the lid |
43c71255 LP |
3523 | status and act on it. This is useful for laptops where the |
3524 | power button is on the outside of the chassis so that it can | |
ed28905e | 3525 | be reached without opening the lid (such as the Lenovo |
b8bde116 | 3526 | Yoga). On those machines, logind will now immediately |
ed28905e | 3527 | re-suspend the machine if the power button has been |
43c71255 LP |
3528 | accidentally pressed while the laptop was suspended and in a |
3529 | backpack or similar. | |
3530 | ||
3531 | * logind will now watch SW_DOCK switches and inhibit reaction | |
3532 | to the lid switch if it is pressed. This means that logind | |
d27893ef | 3533 | will not suspend the machine anymore if the lid is closed |
949138cc | 3534 | and the system is docked, if the laptop supports SW_DOCK |
43c71255 LP |
3535 | notifications via the input layer. Note that ACPI docking |
3536 | stations do not generate this currently. Also note that this | |
3537 | logic is usually not fully sufficient and Desktop | |
3538 | Environments should take a lid switch inhibitor lock when an | |
3539 | external display is connected, as systemd will not watch | |
3540 | this on its own. | |
3541 | ||
3542 | * nspawn will now make use of the devices cgroup controller by | |
3543 | default, and only permit creation of and access to the usual | |
3544 | API device nodes like /dev/null or /dev/random, as well as | |
3545 | access to (but not creation of) the pty devices. | |
3546 | ||
3547 | * We will now ship a default .network file for | |
3548 | systemd-networkd that automatically configures DHCP for | |
3549 | network interfaces created by nspawn's --network-veth or | |
3550 | --network-bridge= switches. | |
3551 | ||
3552 | * systemd will now understand the usual M, K, G, T suffixes | |
3553 | according to SI conventions (i.e. to the base 1000) when | |
3554 | referring to throughput and hardware metrics. It will stay | |
3555 | with IEC conventions (i.e. to the base 1024) for software | |
3556 | metrics, according to what is customary according to | |
3557 | Wikipedia. We explicitly document which base applies for | |
3558 | each configuration option. | |
3559 | ||
3560 | * The DeviceAllow= setting in unit files now supports a syntax | |
ed28905e | 3561 | to whitelist an entire group of devices node majors at once, |
43c71255 | 3562 | based on the /proc/devices listing. For example, with the |
b8bde116 | 3563 | string "char-pts", it is now possible to whitelist all |
43c71255 LP |
3564 | current and future pseudo-TTYs at once. |
3565 | ||
3566 | * sd-event learned a new "post" event source. Event sources of | |
3567 | this type are triggered by the dispatching of any event | |
3568 | source of a type that is not "post". This is useful for | |
3569 | implementing clean-up and check event sources that are | |
3570 | triggered by other work being done in the program. | |
3571 | ||
3572 | * systemd-networkd is no longer statically enabled, but uses | |
3573 | the usual [Install] sections so that it can be | |
3574 | enabled/disabled using systemctl. It still is enabled by | |
3575 | default however. | |
3576 | ||
b8bde116 | 3577 | * When creating a veth interface pair with systemd-nspawn, the |
43c71255 LP |
3578 | host side will now be prefixed with "vb-" if |
3579 | --network-bridge= is used, and with "ve-" if --network-veth | |
b8bde116 | 3580 | is used. This way, it is easy to distinguish these cases on |
43c71255 LP |
3581 | the host, for example to apply different configuration to |
3582 | them with systemd-networkd. | |
3583 | ||
d27893ef LP |
3584 | * The compatibility libraries for libsystemd-journal.so, |
3585 | libsystem-id128.so, libsystemd-login.so and | |
3586 | libsystemd-daemon.so do not make use of IFUNC | |
b8bde116 | 3587 | anymore. Instead, we now build libsystemd.so multiple times |
d27893ef LP |
3588 | under these alternative names. This means that the footprint |
3589 | is drastically increased, but given that these are | |
b8bde116 | 3590 | transitional compatibility libraries, this should not matter |
d27893ef LP |
3591 | much. This change has been made necessary to support the ARM |
3592 | platform for these compatibility libraries, as the ARM | |
d28315e4 | 3593 | toolchain is not really at the same level as the toolchain |
ed28905e | 3594 | for other architectures like x86 and does not support |
d27893ef LP |
3595 | IFUNC. Please make sure to use --enable-compat-libs only |
3596 | during a transitional period! | |

43c71255 | 3608 | |
e49b5aad LP |
3609 | CHANGES WITH 209: |
3610 | ||
3611 | * A new component "systemd-networkd" has been added that can | |
3612 | be used to configure local network interfaces statically or | |
8b7d0494 JSJ |
3613 | via DHCP. It is capable of bringing up bridges, VLANs, and |
3614 | bonding. Currently, no hook-ups for interactive network | |
4670e9d5 | 3615 | configuration are provided. Use this for your initrd, |
8b7d0494 JSJ |
3616 | container, embedded, or server setup if you need a simple, |
3617 | yet powerful, network configuration solution. This | |
4670e9d5 | 3618 | configuration subsystem is quite nifty, as it allows wildcard |
1e190502 | 3619 | hotplug matching in interfaces. For example, with a single |
4670e9d5 | 3620 | configuration snippet, you can configure that all Ethernet |
1e190502 ZJS |
3621 | interfaces showing up are automatically added to a bridge, |
3622 | or similar. It supports link-sensing and more. | |
e49b5aad LP |
3623 | |
3624 | * A new tool "systemd-socket-proxyd" has been added which can | |
4c2413bf | 3625 | act as a bidirectional proxy for TCP sockets. This is |
e49b5aad LP |
3626 | useful for adding socket activation support to services that |
3627 | do not actually support socket activation, including virtual | |
4c2413bf | 3628 | machines and the like. |
e49b5aad LP |
3629 | |
3630 | * Add a new tool to save/restore rfkill state on | |
3631 | shutdown/boot. | |
3632 | ||
8b7d0494 JSJ |
3633 | * Save/restore state of keyboard backlights in addition to |
3634 | display backlights on shutdown/boot. | |
e49b5aad LP |
3635 | |
3636 | * udev learned a new SECLABEL{} construct to label device | |
3637 | nodes with a specific security label when they appear. For | |
4c2413bf | 3638 | now, only SECLABEL{selinux} is supported, but the syntax is |
e49b5aad LP |
3639 | prepared for additional security frameworks. |
3640 | ||
3641 | * udev gained a new scheme to configure link-level attributes | |
3642 | from files in /etc/systemd/network/*.link. These files can | |
8b7d0494 | 3643 | match against MAC address, device path, driver name and type, |
4c2413bf | 3644 | and will apply attributes like the naming policy, link speed, |
8b7d0494 | 3645 | MTU, duplex settings, Wake-on-LAN settings, MAC address, MAC |
e49b5aad LP |
3646 | address assignment policy (randomized, ...). |
3647 | ||
dfb08b05 ZJS |
3648 | * The configuration of network interface naming rules for |
3649 | "permanent interface names" has changed: a new NamePolicy= | |
3650 | setting in the [Link] section of .link files determines the | |
a8eaaee7 | 3651 | priority of possible naming schemes (onboard, slot, MAC, |
dfb08b05 ZJS |
3652 | path). The default value of this setting is determined by |
3653 | /usr/lib/net/links/99-default.link. Old | |
3654 | 80-net-name-slot.rules udev configuration file has been | |
3655 | removed, so local configuration overriding this file should | |
3656 | be adapated to override 99-default.link instead. | |
3657 | ||
e49b5aad | 3658 | * When the User= switch is used in a unit file, also |
4c2413bf | 3659 | initialize $SHELL= based on the user database entry. |
e49b5aad LP |
3660 | |
3661 | * systemd no longer depends on libdbus. All communication is | |
3662 | now done with sd-bus, systemd's low-level bus library | |
3663 | implementation. | |
3664 | ||
3665 | * kdbus support has been added to PID 1 itself. When kdbus is | |
4c2413bf | 3666 | enabled, this causes PID 1 to set up the system bus and |
e49b5aad LP |
3667 | enable support for a new ".busname" unit type that |
3668 | encapsulates bus name activation on kdbus. It works a little | |
3669 | bit like ".socket" units, except for bus names. A new | |
3670 | generator has been added that converts classic dbus1 service | |
3671 | activation files automatically into native systemd .busname | |
3672 | and .service units. | |
3673 | ||
3674 | * sd-bus: add a light-weight vtable implementation that allows | |
3675 | defining objects on the bus with a simple static const | |
3676 | vtable array of its methods, signals and properties. | |
3677 | ||
8b7d0494 | 3678 | * systemd will not generate or install static dbus |
e49b5aad | 3679 | introspection data anymore to /usr/share/dbus-1/interfaces, |
1e190502 | 3680 | as the precise format of these files is unclear, and |
e49b5aad LP |
3681 | nothing makes use of it. |
3682 | ||
3683 | * A proxy daemon is now provided to proxy clients connecting | |
3684 | via classic D-Bus AF_UNIX sockets to kdbus, to provide full | |
3685 | compatibility with classic D-Bus. | |
3686 | ||
3687 | * A bus driver implementation has been added that supports the | |
3688 | classic D-Bus bus driver calls on kdbus, also for | |
3689 | compatibility purposes. | |
3690 | ||
3691 | * A new API "sd-event.h" has been added that implements a | |
3692 | minimal event loop API built around epoll. It provides a | |
3693 | couple of features that direct epoll usage is lacking: | |
b9761003 | 3694 | prioritization of events, scales to large numbers of timer |
e49b5aad LP |
3695 | events, per-event timer slack (accuracy), system-wide |
3696 | coalescing of timer events, exit handlers, watchdog | |
3697 | supervision support using systemd's sd_notify() API, child | |
3698 | process handling. | |
3699 | ||
3700 | * A new API "sd-rntl.h" has been added that provides an API | |
3701 | around the route netlink interface of the kernel, similar in | |
3702 | style to "sd-bus.h". | |
3703 | ||
7e95eda5 PF |
3704 | * A new API "sd-dhcp-client.h" has been added that provides a |
3705 | small DHCPv4 client-side implementation. This is used by | |
e49b5aad LP |
3706 | "systemd-networkd". |
3707 | ||
4c2413bf | 3708 | * There is a new kernel command line option |
8b7d0494 JSJ |
3709 | "systemd.restore_state=0|1". When set to "0", none of the |
3710 | systemd tools will restore saved runtime state to hardware | |
3711 | devices. More specifically, the rfkill and backlight states | |
3712 | are not restored. | |
e49b5aad LP |
3713 | |
3714 | * The FsckPassNo= compatibility option in mount/service units | |
3715 | has been removed. The fstab generator will now add the | |
3716 | necessary dependencies automatically, and does not require | |
3717 | PID1's support for that anymore. | |
3718 | ||
8b7d0494 | 3719 | * journalctl gained a new switch, --list-boots, that lists |
e49b5aad LP |
3720 | recent boots with their times and boot IDs. |
3721 | ||
3722 | * The various tools like systemctl, loginctl, timedatectl, | |
3723 | busctl, systemd-run, ... have gained a new switch "-M" to | |
3724 | connect to a specific, local OS container (as direct | |
3725 | connection, without requiring SSH). This works on any | |
3726 | container that is registered with machined, such as those | |
3727 | created by libvirt-lxc or nspawn. | |
3728 | ||
3729 | * systemd-run and systemd-analyze also gained support for "-H" | |
4c2413bf | 3730 | to connect to remote hosts via SSH. This is particularly |
8b7d0494 JSJ |
3731 | useful for systemd-run because it enables queuing of jobs |
3732 | onto remote systems. | |
e49b5aad LP |
3733 | |
3734 | * machinectl gained a new command "login" to open a getty | |
3735 | login in any local container. This works with any container | |
3736 | that is registered with machined (such as those created by | |
8e420494 | 3737 | libvirt-lxc or nspawn), and which runs systemd inside. |
e49b5aad LP |
3738 | |
3739 | * machinectl gained a new "reboot" command that may be used to | |
3740 | trigger a reboot on a specific container that is registered | |
3741 | with machined. This works on any container that runs an init | |
3742 | system of some kind. | |
3743 | ||
3744 | * systemctl gained a new "list-timers" command to print a nice | |
3745 | listing of installed timer units with the times they elapse | |
3746 | next. | |
3747 | ||
3748 | * Alternative reboot() parameters may now be specified on the | |
3749 | "systemctl reboot" command line and are passed to the | |
3750 | reboot() system call. | |
3751 | ||
3752 | * systemctl gained a new --job-mode= switch to configure the | |
3753 | mode to queue a job with. This is a more generic version of | |
8b7d0494 | 3754 | --fail, --irreversible, and --ignore-dependencies, which are |
e49b5aad LP |
3755 | still available but not advertised anymore. |
3756 | ||
e49b5aad LP |
3757 | * /etc/systemd/system.conf gained new settings to configure |
3758 | various default timeouts of units, as well as the default | |
b9761003 | 3759 | start limit interval and burst. These may still be overridden |
e49b5aad LP |
3760 | within each Unit. |
3761 | ||
270f1624 LP |
3762 | * PID1 will now export on the bus profile data of the security |
3763 | policy upload process (such as the SELinux policy upload to | |
8e420494 | 3764 | the kernel). |
e49b5aad | 3765 | |
4670e9d5 | 3766 | * journald: when forwarding logs to the console, include |
1e190502 ZJS |
3767 | timestamps (following the setting in |
3768 | /sys/module/printk/parameters/time). | |
e49b5aad LP |
3769 | |
3770 | * OnCalendar= in timer units now understands the special | |
3771 | strings "yearly" and "annually". (Both are equivalent) | |
3772 | ||
3773 | * The accuracy of timer units is now configurable with the new | |
3774 | AccuracySec= setting. It defaults to 1min. | |
3775 | ||
3776 | * A new dependency type JoinsNamespaceOf= has been added that | |
3777 | allows running two services within the same /tmp and network | |
3778 | namespace, if PrivateNetwork= or PrivateTmp= are used. | |
3779 | ||
3780 | * A new command "cat" has been added to systemctl. It outputs | |
3781 | the original unit file of a unit, and concatenates the | |
1e190502 ZJS |
3782 | contents of additional "drop-in" unit file snippets, so that |
3783 | the full configuration is shown. | |
e49b5aad LP |
3784 | |
3785 | * systemctl now supports globbing on the various "list-xyz" | |
3786 | commands, like "list-units" or "list-sockets", as well as on | |
1e190502 ZJS |
3787 | those commands which take multiple unit names. |
3788 | ||
3789 | * journalctl's --unit= switch gained support for globbing. | |
e49b5aad LP |
3790 | |
3791 | * All systemd daemons now make use of the watchdog logic so | |
3792 | that systemd automatically notices when they hang. | |
3793 | ||
4c2413bf | 3794 | * If the $container_ttys environment variable is set, |
e49b5aad LP |
3795 | getty-generator will automatically spawn a getty for each |
3796 | listed tty. This is useful for container managers to request | |
3797 | login gettys to be spawned on as many ttys as needed. | |
3798 | ||
3799 | * %h, %s, %U specifier support is not available anymore when | |
3800 | used in unit files for PID 1. This is because NSS calls are | |
3801 | not safe from PID 1. They stay available for --user | |
3802 | instances of systemd, and as special case for the root user. | |
3803 | ||
e49b5aad LP |
3804 | * loginctl gained a new "--no-legend" switch to turn off output |
3805 | of the legend text. | |
3806 | ||
3807 | * The "sd-login.h" API gained three new calls: | |
3808 | sd_session_is_remote(), sd_session_get_remote_user(), | |
3809 | sd_session_get_remote_host() to query information about | |
3810 | remote sessions. | |
3811 | ||
8e420494 LP |
3812 | * The udev hardware database now also carries vendor/product |
3813 | information of SDIO devices. | |
e49b5aad LP |
3814 | |
3815 | * The "sd-daemon.h" API gained a new sd_watchdog_enabled() to | |
3816 | determine whether watchdog notifications are requested by | |
3817 | the system manager. | |
3818 | ||
1e190502 | 3819 | * Socket-activated per-connection services now include a |
e49b5aad LP |
3820 | short description of the connection parameters in the |
3821 | description. | |
3822 | ||
4c2413bf | 3823 | * tmpfiles gained a new "--boot" option. When this is not used, |
e49b5aad | 3824 | only lines where the command character is not suffixed with |
4670e9d5 | 3825 | "!" are executed. When this option is specified, those |
1e190502 ZJS |
3826 | options are executed too. This partitions tmpfiles |
3827 | directives into those that can be safely executed at any | |
3828 | time, and those which should be run only at boot (for | |
3829 | example, a line that creates /run/nologin). | |
e49b5aad | 3830 | |
c0c5af00 | 3831 | * A new API "sd-resolve.h" has been added which provides a simple |
4c2413bf | 3832 | asynchronous wrapper around glibc NSS host name resolution |
e49b5aad | 3833 | calls, such as getaddrinfo(). In contrast to glibc's |
4c2413bf JE |
3834 | getaddrinfo_a(), it does not use signals. In contrast to most |
3835 | other asynchronous name resolution libraries, this one does | |
3836 | not reimplement DNS, but reuses NSS, so that alternate | |
e49b5aad | 3837 | host name resolution systems continue to work, such as mDNS, |
8b7d0494 | 3838 | LDAP, etc. This API is based on libasyncns, but it has been |
e49b5aad LP |
3839 | cleaned up for inclusion in systemd. |
3840 | ||
6300b3ec LP |
3841 | * The APIs "sd-journal.h", "sd-login.h", "sd-id128.h", |
3842 | "sd-daemon.h" are no longer found in individual libraries | |
3843 | libsystemd-journal.so, libsystemd-login.so, | |
3844 | libsystemd-id128.so, libsystemd-daemon.so. Instead, we have | |
8b7d0494 JSJ |
3845 | merged them into a single library, libsystemd.so, which |
3846 | provides all symbols. The reason for this is cyclic | |
e49b5aad | 3847 | dependencies, as these libraries tend to use each other's |
d28315e4 | 3848 | symbols. So far, we have managed to workaround that by linking |
6300b3ec LP |
3849 | a copy of a good part of our code into each of these |
3850 | libraries again and again, which, however, makes certain | |
3851 | things hard to do, like sharing static variables. Also, it | |
3852 | substantially increases footprint. With this change, there | |
3853 | is only one library for the basic APIs systemd | |
3854 | provides. Also, "sd-bus.h", "sd-memfd.h", "sd-event.h", | |
3855 | "sd-rtnl.h", "sd-resolve.h", "sd-utf8.h" are found in this | |
3856 | library as well, however are subject to the --enable-kdbus | |
3857 | switch (see below). Note that "sd-dhcp-client.h" is not part | |
3858 | of this library (this is because it only consumes, never | |
3859 | provides, services of/to other APIs). To make the transition | |
8b7d0494 | 3860 | easy from the separate libraries to the unified one, we |
4c2413bf | 3861 | provide the --enable-compat-libs compile-time switch which |
e49b5aad LP |
3862 | will generate stub libraries that are compatible with the |
3863 | old ones but redirect all calls to the new one. | |
3864 | ||
8b7d0494 | 3865 | * All of the kdbus logic and the new APIs "sd-bus.h", |
e49b5aad | 3866 | "sd-memfd.h", "sd-event.h", "sd-rtnl.h", "sd-resolve.h", |
8b7d0494 JSJ |
3867 | and "sd-utf8.h" are compile-time optional via the |
3868 | "--enable-kdbus" switch, and they are not compiled in by | |
3869 | default. To make use of kdbus, you have to explicitly enable | |
4c2413bf | 3870 | the switch. Note however, that neither the kernel nor the |
e49b5aad LP |
3871 | userspace API for all of this is considered stable yet. We |
3872 | want to maintain the freedom to still change the APIs for | |
4c2413bf | 3873 | now. By specifying this build-time switch, you acknowledge |
e49b5aad | 3874 | that you are aware of the instability of the current |
ad42cf73 KS |
3875 | APIs. |
3876 | ||
3877 | * Also, note that while kdbus is pretty much complete, | |
e49b5aad | 3878 | it lacks one thing: proper policy support. This means you |
8b7d0494 | 3879 | can build a fully working system with all features; however, |
4c2413bf JE |
3880 | it will be highly insecure. Policy support will be added in |
3881 | one of the next releases, at the same time that we will | |
3882 | declare the APIs stable. | |
e49b5aad | 3883 | |
81c7dd89 | 3884 | * When the kernel command line argument "kdbus" is specified, |
ad42cf73 | 3885 | systemd will automatically load the kdbus.ko kernel module. At |
8b7d0494 | 3886 | this stage of development, it is only useful for testing kdbus |
ad42cf73 | 3887 | and should not be used in production. Note: if "--enable-kdbus" |
8b7d0494 | 3888 | is specified, and the kdbus.ko kernel module is available, and |
ad42cf73 KS |
3889 | "kdbus" is added to the kernel command line, the entire system |
3890 | runs with kdbus instead of dbus-daemon, with the above mentioned | |
3891 | problem of missing the system policy enforcement. Also a future | |
3892 | version of kdbus.ko or a newer systemd will not be compatible with | |
3893 | each other, and will unlikely be able to boot the machine if only | |
3894 | one of them is updated. | |
3895 | ||
e49b5aad | 3896 | * systemctl gained a new "import-environment" command which |
4c2413bf | 3897 | uploads the caller's environment (or parts thereof) into the |
e49b5aad LP |
3898 | service manager so that it is inherited by services started |
3899 | by the manager. This is useful to upload variables like | |
3900 | $DISPLAY into the user service manager. | |
3901 | ||
3902 | * A new PrivateDevices= switch has been added to service units | |
3903 | which allows running a service with a namespaced /dev | |
3904 | directory that does not contain any device nodes for | |
4c2413bf | 3905 | physical devices. More specifically, it only includes devices |
8b7d0494 | 3906 | such as /dev/null, /dev/urandom, and /dev/zero which are API |
e49b5aad LP |
3907 | entry points. |
3908 | ||
3909 | * logind has been extended to support behaviour like VT | |
3910 | switching on seats that do not support a VT. This makes | |
3911 | multi-session available on seats that are not the first seat | |
3912 | (seat0), and on systems where kernel support for VTs has | |
8b7d0494 | 3913 | been disabled at compile-time. |
e49b5aad LP |
3914 | |
3915 | * If a process holds a delay lock for system sleep or shutdown | |
1e190502 | 3916 | and fails to release it in time, we will now log its |
e49b5aad LP |
3917 | identity. This makes it easier to identify processes that |
3918 | cause slow suspends or power-offs. | |
3919 | ||
1e190502 ZJS |
3920 | * When parsing /etc/crypttab, support for a new key-slot= |
3921 | option as supported by Debian is added. It allows indicating | |
3922 | which LUKS slot to use on disk, speeding up key loading. | |
e49b5aad | 3923 | |
1e190502 ZJS |
3924 | * The sd_journald_sendv() API call has been checked and |
3925 | officially declared to be async-signal-safe so that it may | |
3926 | be invoked from signal handlers for logging purposes. | |
e49b5aad LP |
3927 | |
3928 | * Boot-time status output is now enabled automatically after a | |
3929 | short timeout if boot does not progress, in order to give | |
8e420494 | 3930 | the user an indication what she or he is waiting for. |
1e190502 ZJS |
3931 | |
3932 | * The boot-time output has been improved to show how much time | |
3933 | remains until jobs expire. | |
e49b5aad LP |
3934 | |
3935 | * The KillMode= switch in service units gained a new possible | |
8b7d0494 | 3936 | value "mixed". If set, and the unit is shut down, then the |
e49b5aad | 3937 | initial SIGTERM signal is sent only to the main daemon |
8e420494 | 3938 | process, while the following SIGKILL signal is sent to |
e49b5aad LP |
3939 | all remaining processes of the service. |
3940 | ||
4c2413bf JE |
3941 | * When a scope unit is registered, a new property "Controller" |
3942 | may be set. If set to a valid bus name, systemd will send a | |
e49b5aad LP |
3943 | RequestStop() signal to this name when it would like to shut |
3944 | down the scope. This may be used to hook manager logic into | |
3945 | the shutdown logic of scope units. Also, scope units may now | |
8b7d0494 | 3946 | be put in a special "abandoned" state, in which case the |
e49b5aad LP |
3947 | manager process which created them takes no further |
3948 | responsibilities for it. | |
3949 | ||
1e190502 | 3950 | * When reading unit files, systemd will now verify |
e49b5aad LP |
3951 | the access mode of these files, and warn about certain |
3952 | suspicious combinations. This has been added to make it | |
3953 | easier to track down packaging bugs where unit files are | |
3954 | marked executable or world-writable. | |
3955 | ||
3956 | * systemd-nspawn gained a new "--setenv=" switch to set | |
8b7d0494 | 3957 | container-wide environment variables. The similar option in |
1e190502 ZJS |
3958 | systemd-activate was renamed from "--environment=" to |
3959 | "--setenv=" for consistency. | |
e49b5aad LP |
3960 | |
3961 | * systemd-nspawn has been updated to create a new kdbus domain | |
3962 | for each container that is invoked, thus allowing each | |
b9761003 | 3963 | container to have its own set of system and user buses, |
8b7d0494 | 3964 | independent of the host. |
e49b5aad LP |
3965 | |
3966 | * systemd-nspawn gained a new --drop-capability= switch to run | |
3967 | the container with less capabilities than the default. Both | |
b9761003 | 3968 | --drop-capability= and --capability= now take the special |
e49b5aad LP |
3969 | string "all" for dropping or keeping all capabilities. |
3970 | ||
3971 | * systemd-nspawn gained new switches for executing containers | |
3972 | with specific SELinux labels set. | |
3973 | ||
3974 | * systemd-nspawn gained a new --quiet switch to not generate | |
3975 | any additional output but the container's own console | |
3976 | output. | |
3977 | ||
3978 | * systemd-nspawn gained a new --share-system switch to run a | |
3979 | container without PID namespacing enabled. | |
3980 | ||
3981 | * systemd-nspawn gained a new --register= switch to control | |
1e190502 | 3982 | whether the container is registered with systemd-machined or |
8e420494 | 3983 | not. This is useful for containers that do not run full |
e49b5aad LP |
3984 | OS images, but only specific apps. |
3985 | ||
3986 | * systemd-nspawn gained a new --keep-unit which may be used | |
8b7d0494 | 3987 | when invoked as the only program from a service unit, and |
e49b5aad | 3988 | results in registration of the unit service itself in |
1e190502 | 3989 | systemd-machined, instead of a newly opened scope unit. |
e49b5aad LP |
3990 | |
3991 | * systemd-nspawn gained a new --network-interface= switch for | |
3992 | moving arbitrary interfaces to the container. The new | |
4c2413bf | 3993 | --network-veth switch creates a virtual Ethernet connection |
8b7d0494 JSJ |
3994 | between host and container. The new --network-bridge= |
3995 | switch then allows assigning the host side of this virtual | |
3996 | Ethernet connection to a bridge device. | |
e49b5aad | 3997 | |
6afc95b7 LP |
3998 | * systemd-nspawn gained a new --personality= switch for |
3999 | setting the kernel personality for the container. This is | |
70a44afe | 4000 | useful when running a 32-bit container on a 64-bit host. A |
b8bde116 JE |
4001 | similar option Personality= is now also available for service |
4002 | units to use. | |
6afc95b7 | 4003 | |
e49b5aad LP |
4004 | * logind will now also track a "Desktop" identifier for each |
4005 | session which encodes the desktop environment of it. This is | |
4006 | useful for desktop environments that want to identify | |
4007 | multiple running sessions of itself easily. | |
4008 | ||
4009 | * A new SELinuxContext= setting for service units has been | |
4010 | added that allows setting a specific SELinux execution | |
4011 | context for a service. | |
4012 | ||
4013 | * Most systemd client tools will now honour $SYSTEMD_LESS for | |
4014 | settings of the "less" pager. By default, these tools will | |
8b7d0494 JSJ |
4015 | override $LESS to allow certain operations to work, such as |
4016 | jump-to-the-end. With $SYSTEMD_LESS, it is possible to | |
e49b5aad LP |
4017 | influence this logic. |
4018 | ||
4019 | * systemd's "seccomp" hook-up has been changed to make use of | |
4020 | the libseccomp library instead of using its own | |
4021 | implementation. This has benefits for portability among | |
4022 | other things. | |
4023 | ||
4c2413bf | 4024 | * For usage together with SystemCallFilter=, a new |
8b7d0494 | 4025 | SystemCallErrorNumber= setting has been introduced that |
b8bde116 JE |
4026 | allows configuration of a system error number to be returned |
4027 | on filtered system calls, instead of immediately killing the | |
e49b5aad LP |
4028 | process. Also, SystemCallArchitectures= has been added to |
4029 | limit access to system calls of a particular architecture | |
4030 | (in order to turn off support for unused secondary | |
4c2413bf | 4031 | architectures). There is also a global |
8b7d0494 | 4032 | SystemCallArchitectures= setting in system.conf now to turn |
e49b5aad LP |
4033 | off support for non-native system calls system-wide. |
4034 | ||
210054d7 KS |
4035 | * systemd requires a kernel with a working name_to_handle_at(), |
4036 | please see the kernel config requirements in the README file. | |

cd4010b3 LP |
4065 | CHANGES WITH 208: |
4066 | ||
4067 | * logind has gained support for facilitating privileged input | |
4068 | and drm device access for unprivileged clients. This work is | |
4069 | useful to allow Wayland display servers (and similar | |
4070 | programs, such as kmscon) to run under the user's ID and | |
4071 | access input and drm devices which are normally | |
4072 | protected. When this is used (and the kernel is new enough) | |
4073 | logind will "mute" IO on the file descriptors passed to | |
4074 | Wayland as long as it is in the background and "unmute" it | |
4075 | if it returns into the foreground. This allows secure | |
4076 | session switching without allowing background sessions to | |
4077 | eavesdrop on input and display data. This also introduces | |
4078 | session switching support if VT support is turned off in the | |
4079 | kernel, and on seats that are not seat0. | |
4080 | ||
4081 | * A new kernel command line option luks.options= is understood | |
06b643e7 | 4082 | now which allows specifying LUKS options for usage for LUKS |
cd4010b3 LP |
4083 | encrypted partitions specified with luks.uuid=. |
4084 | ||
4085 | * tmpfiles.d(5) snippets may now use specifier expansion in | |
4086 | path names. More specifically %m, %b, %H, %v, are now | |
4087 | replaced by the local machine id, boot id, hostname, and | |
4088 | kernel version number. | |
4089 | ||
4090 | * A new tmpfiles.d(5) command "m" has been introduced which | |
4091 | may be used to change the owner/group/access mode of a file | |
d28315e4 | 4092 | or directory if it exists, but do nothing if it does not. |
cd4010b3 LP |
4093 | |
4094 | * This release removes high-level support for the | |
4095 | MemorySoftLimit= cgroup setting. The underlying kernel | |
4096 | cgroup attribute memory.soft_limit= is currently badly | |
4097 | designed and likely to be removed from the kernel API in its | |
d28315e4 | 4098 | current form, hence we should not expose it for now. |
cd4010b3 LP |
4099 | |
4100 | * The memory.use_hierarchy cgroup attribute is now enabled for | |
4101 | all cgroups systemd creates in the memory cgroup | |
4102 | hierarchy. This option is likely to be come the built-in | |
cc98b302 TH |
4103 | default in the kernel anyway, and the non-hierarchical mode |
4104 | never made much sense in the intrinsically hierarchical | |
cd4010b3 LP |
4105 | cgroup system. |
4106 | ||
4107 | * A new field _SYSTEMD_SLICE= is logged along with all journal | |
4108 | messages containing the slice a message was generated | |
4109 | from. This is useful to allow easy per-customer filtering of | |
4110 | logs among other things. | |
4111 | ||
4112 | * systemd-journald will no longer adjust the group of journal | |
4113 | files it creates to the "systemd-journal" group. Instead we | |
4114 | rely on the journal directory to be owned by the | |
4115 | "systemd-journal" group, and its setgid bit set, so that the | |
4116 | kernel file system layer will automatically enforce that | |
4117 | journal files inherit this group assignment. The reason for | |
4118 | this change is that we cannot allow NSS look-ups from | |
4119 | journald which would be necessary to resolve | |
4120 | "systemd-journal" to a numeric GID, because this might | |
4121 | create deadlocks if NSS involves synchronous queries to | |
4122 | other daemons (such as nscd, or sssd) which in turn are | |
4123 | logging clients of journald and might block on it, which | |
4124 | would then dead lock. A tmpfiles.d(5) snippet included in | |
4125 | systemd will make sure the setgid bit and group are | |
4126 | properly set on the journal directory if it exists on every | |
4127 | boot. However, we recommend adjusting it manually after | |
4128 | upgrades too (or from RPM scriptlets), so that the change is | |
4129 | not delayed until next reboot. | |
4130 | ||
4131 | * Backlight and random seed files in /var/lib/ have moved into | |
4132 | the /var/lib/systemd/ directory, in order to centralize all | |
4133 | systemd generated files in one directory. | |
4134 | ||
4135 | * Boot time performance measurements (as displayed by | |
4136 | "systemd-analyze" for example) will now read ACPI 5.0 FPDT | |
4137 | performance information if that's available to determine how | |
4138 | much time BIOS and boot loader initialization required. With | |
4139 | a sufficiently new BIOS you hence no longer need to boot | |
4140 | with Gummiboot to get access to such information. | |

4f0be680 LP |
4152 | CHANGES WITH 207: |
4153 | ||
4154 | * The Restart= option for services now understands a new | |
f3a165b0 | 4155 | on-watchdog setting, which will restart the service |
4f0be680 LP |
4156 | automatically if the service stops sending out watchdog keep |
4157 | alive messages (as configured with WatchdogSec=). | |
4158 | ||
4159 | * The getty generator (which is responsible for bringing up a | |
4160 | getty on configured serial consoles) will no longer only | |
4161 | start a getty on the primary kernel console but on all | |
4162 | others, too. This makes the order in which console= is | |
4163 | specified on the kernel command line less important. | |
4164 | ||
4165 | * libsystemd-logind gained a new sd_session_get_vt() call to | |
4166 | retrieve the VT number of a session. | |
4167 | ||
4168 | * If the option "tries=0" is set for an entry of /etc/crypttab | |
4169 | its passphrase is queried indefinitely instead of any | |
4170 | maximum number of tries. | |
4171 | ||
4172 | * If a service with a configure PID file terminates its PID | |
4173 | file will now be removed automatically if it still exists | |
4174 | afterwards. This should put an end to stale PID files. | |
4175 | ||
4176 | * systemd-run will now also take relative binary path names | |
4177 | for execution and no longer insists on absolute paths. | |
4178 | ||
4179 | * InaccessibleDirectories= and ReadOnlyDirectories= now take | |
4180 | paths that are optionally prefixed with "-" to indicate that | |
d28315e4 | 4181 | it should not be considered a failure if they do not exist. |
4f0be680 | 4182 | |
f3a165b0 KS |
4183 | * journalctl -o (and similar commands) now understands a new |
4184 | output mode "short-precise", it is similar to "short" but | |
4f0be680 LP |
4185 | shows timestamps with usec accuracy. |
4186 | ||
4187 | * The option "discard" (as known from Debian) is now | |
4188 | synonymous to "allow-discards" in /etc/crypttab. In fact, | |
387abf80 | 4189 | "discard" is preferred now (since it is easier to remember |
4f0be680 LP |
4190 | and type). |
4191 | ||
f3a165b0 | 4192 | * Some licensing clean-ups were made, so that more code is now |
4f0be680 LP |
4193 | LGPL-2.1 licensed than before. |
4194 | ||
4195 | * A minimal tool to save/restore the display backlight | |
4196 | brightness across reboots has been added. It will store the | |
f3a165b0 | 4197 | backlight setting as late as possible at shutdown, and |
4f0be680 LP |
4198 | restore it as early as possible during reboot. |
4199 | ||
4200 | * A logic to automatically discover and enable home and swap | |
4201 | partitions on GPT disks has been added. With this in place | |
4202 | /etc/fstab becomes optional for many setups as systemd can | |
4203 | discover certain partitions located on the root disk | |
4204 | automatically. Home partitions are recognized under their | |
4205 | GPT type ID 933ac7e12eb44f13b8440e14e2aef915. Swap | |
4206 | partitions are recognized under their GPT type ID | |
4207 | 0657fd6da4ab43c484e50933c84b4f4f. | |
4208 | ||
4209 | * systemd will no longer pass any environment from the kernel | |
4210 | or initrd to system services. If you want to set an | |
4211 | environment for all services, do so via the kernel command | |
4212 | line systemd.setenv= assignment. | |
4213 | ||
387abf80 LP |
4214 | * The systemd-sysctl tool no longer natively reads the file |
4215 | /etc/sysctl.conf. If desired, the file should be symlinked | |
4216 | from /etc/sysctl.d/99-sysctl.conf. Apart from providing | |
4217 | legacy support by a symlink rather than built-in code, it | |
4218 | also makes the otherwise hidden order of application of the | |
4219 | different files visible. (Note that this partly reverts to a | |
4220 | pre-198 application order of sysctl knobs!) | |
04bf3c1a | 4221 | |
4f0be680 LP |
4222 | * The "systemctl set-log-level" and "systemctl dump" commands |
4223 | have been moved to systemd-analyze. | |
4224 | ||
4225 | * systemd-run learned the new --remain-after-exit switch, | |
4226 | which causes the scope unit not to be cleaned up | |
4227 | automatically after the process terminated. | |
4228 | ||
4229 | * tmpfiles learned a new --exclude-prefix= switch to exclude | |
4230 | certain paths from operation. | |
4231 | ||
4232 | * journald will now automatically flush all messages to disk | |
f47ad593 ZJS |
4233 | as soon as a message at the log level CRIT, ALERT or EMERG |
4234 | is received. | |

4f0be680 | 4251 | |
408f281b LP |
4252 | CHANGES WITH 206: |
4253 | ||
4254 | * The documentation has been updated to cover the various new | |
4255 | concepts introduced with 205. | |
4256 | ||
4257 | * Unit files now understand the new %v specifier which | |
4258 | resolves to the kernel version string as returned by "uname | |
4259 | -r". | |
4260 | ||
4261 | * systemctl now supports filtering the unit list output by | |
4262 | load state, active state and sub state, using the new | |
33b521be | 4263 | --state= parameter. |
408f281b LP |
4264 | |
4265 | * "systemctl status" will now show the results of the | |
4266 | condition checks (like ConditionPathExists= and similar) of | |
4267 | the last start attempts of the unit. They are also logged to | |
4268 | the journal. | |
4269 | ||
4270 | * "journalctl -b" may now be used to look for boot output of a | |
4271 | specific boot. Try "journalctl -b -1" for the previous boot, | |
4272 | but the syntax is substantially more powerful. | |
4273 | ||
4274 | * "journalctl --show-cursor" has been added which prints the | |
4275 | cursor string the last shown log line. This may then be used | |
4276 | with the new "journalctl --after-cursor=" switch to continue | |
4277 | browsing logs from that point on. | |
4278 | ||
4279 | * "journalctl --force" may now be used to force regeneration | |
4280 | of an FSS key. | |
4281 | ||
251cc819 LP |
4282 | * Creation of "dead" device nodes has been moved from udev |
4283 | into kmod and tmpfiles. Previously, udev would read the kmod | |
4284 | databases to pre-generate dead device nodes based on meta | |
4285 | information contained in kernel modules, so that these would | |
4286 | be auto-loaded on access rather then at boot. As this | |
d28315e4 | 4287 | does not really have much to do with the exposing actual |
251cc819 LP |
4288 | kernel devices to userspace this has always been slightly |
4289 | alien in the udev codebase. Following the new scheme kmod | |
4290 | will now generate a runtime snippet for tmpfiles from the | |
4291 | module meta information and it now is tmpfiles' job to the | |
4292 | create the nodes. This also allows overriding access and | |
4293 | other parameters for the nodes using the usual tmpfiles | |
4294 | facilities. As side effect this allows us to remove the | |
4295 | CAP_SYS_MKNOD capability bit from udevd entirely. | |
4296 | ||
4297 | * logind's device ACLs may now be applied to these "dead" | |
4298 | devices nodes too, thus finally allowing managed access to | |
4299 | devices such as /dev/snd/sequencer whithout loading the | |
4300 | backing module right-away. | |
408f281b LP |
4301 | |
4302 | * A new RPM macro has been added that may be used to apply | |
4303 | tmpfiles configuration during package installation. | |
4304 | ||
4305 | * systemd-detect-virt and ConditionVirtualization= now can | |
4306 | detect User-Mode-Linux machines (UML). | |
4307 | ||
251cc819 LP |
4308 | * journald will now implicitly log the effective capabilities |
4309 | set of processes in the message metadata. | |
408f281b LP |
4310 | |
4311 | * systemd-cryptsetup has gained support for TrueCrypt volumes. | |
4312 | ||
4313 | * The initrd interface has been simplified (more specifically, | |
4314 | support for passing performance data via environment | |
4315 | variables and fsck results via files in /run has been | |
4316 | removed). These features were non-essential, and are | |
4317 | nowadays available in a much nicer way by having systemd in | |
4318 | the initrd serialize its state and have the hosts systemd | |
4319 | deserialize it again. | |
4320 | ||
28f5c779 KS |
4321 | * The udev "keymap" data files and tools to apply keyboard |
4322 | specific mappings of scan to key codes, and force-release | |
4323 | scan code lists have been entirely replaced by a udev | |
4324 | "keyboard" builtin and a hwdb data file. | |
408f281b | 4325 | |
251cc819 LP |
4326 | * systemd will now honour the kernel's "quiet" command line |
4327 | argument also during late shutdown, resulting in a | |
4328 | completely silent shutdown when used. | |
4329 | ||
4330 | * There's now an option to control the SO_REUSEPORT socket | |
4331 | option in .socket units. | |
4332 | ||
4333 | * Instance units will now automatically get a per-template | |
4334 | subslice of system.slice unless something else is explicitly | |
4335 | configured. For example, instances of sshd@.service will now | |
4336 | implicitly be placed in system-sshd.slice rather than | |
4337 | system.slice as before. | |
4338 | ||
4339 | * Test coverage support may now be enabled at build time. | |

ccddd104 | 4349 | — Berlin, 2013-07-23 |
4f0be680 | 4350 | |
00aa832b LP |
4351 | CHANGES WITH 205: |
4352 | ||
4353 | * Two new unit types have been introduced: | |
4354 | ||
4355 | Scope units are very similar to service units, however, are | |
ccddd104 | 4356 | created out of pre-existing processes — instead of PID 1 |
00aa832b LP |
4357 | forking off the processes. By using scope units it is |
4358 | possible for system services and applications to group their | |
4359 | own child processes (worker processes) in a powerful way | |
4360 | which then maybe used to organize them, or kill them | |
4361 | together, or apply resource limits on them. | |
4362 | ||
4363 | Slice units may be used to partition system resources in an | |
cc98b302 | 4364 | hierarchical fashion and then assign other units to them. By |
00aa832b LP |
4365 | default there are now three slices: system.slice (for all |
4366 | system services), user.slice (for all user sessions), | |
4367 | machine.slice (for VMs and containers). | |
4368 | ||
4369 | Slices and scopes have been introduced primarily in | |
4370 | context of the work to move cgroup handling to a | |
4371 | single-writer scheme, where only PID 1 | |
4372 | creates/removes/manages cgroups. | |
4373 | ||
4374 | * There's a new concept of "transient" units. In contrast to | |
4375 | normal units these units are created via an API at runtime, | |
4376 | not from configuration from disk. More specifically this | |
4377 | means it is now possible to run arbitrary programs as | |
4378 | independent services, with all execution parameters passed | |
4379 | in via bus APIs rather than read from disk. Transient units | |
4380 | make systemd substantially more dynamic then it ever was, | |
4381 | and useful as a general batch manager. | |
4382 | ||
4383 | * logind has been updated to make use of scope and slice units | |
4384 | for managing user sessions. As a user logs in he will get | |
4385 | his own private slice unit, to which all sessions are added | |
4386 | as scope units. We also added support for automatically | |
4387 | adding an instance of user@.service for the user into the | |
4388 | slice. Effectively logind will no longer create cgroup | |
4389 | hierarchies on its own now, it will defer entirely to PID 1 | |
4390 | for this by means of scope, service and slice units. Since | |
4391 | user sessions this way become entities managed by PID 1 | |
4392 | the output of "systemctl" is now a lot more comprehensive. | |
4393 | ||
4394 | * A new mini-daemon "systemd-machined" has been added which | |
4395 | may be used by virtualization managers to register local | |
4396 | VMs/containers. nspawn has been updated accordingly, and | |
4397 | libvirt will be updated shortly. machined will collect a bit | |
4398 | of meta information about the VMs/containers, and assign | |
4399 | them their own scope unit (see above). The collected | |
4400 | meta-data is then made available via the "machinectl" tool, | |
4401 | and exposed in "ps" and similar tools. machined/machinectl | |
4402 | is compile-time optional. | |
4403 | ||
4404 | * As discussed earlier, the low-level cgroup configuration | |
4405 | options ControlGroup=, ControlGroupModify=, | |
4406 | ControlGroupPersistent=, ControlGroupAttribute= have been | |
4407 | removed. Please use high-level attribute settings instead as | |
4408 | well as slice units. | |
4409 | ||
4410 | * A new bus call SetUnitProperties() has been added to alter | |
4411 | various runtime parameters of a unit. This is primarily | |
4412 | useful to alter cgroup parameters dynamically in a nice way, | |
4413 | but will be extended later on to make more properties | |
4414 | modifiable at runtime. systemctl gained a new set-properties | |
4415 | command that wraps this call. | |
4416 | ||
4417 | * A new tool "systemd-run" has been added which can be used to | |
4418 | run arbitrary command lines as transient services or scopes, | |
4419 | while configuring a number of settings via the command | |
4420 | line. This tool is currently very basic, however already | |
4421 | very useful. We plan to extend this tool to even allow | |
4422 | queuing of execution jobs with time triggers from the | |
4423 | command line, similar in fashion to "at". | |
4424 | ||
4425 | * nspawn will now inform the user explicitly that kernels with | |
4426 | audit enabled break containers, and suggest the user to turn | |
4427 | off audit. | |
4428 | ||
4429 | * Support for detecting the IMA and AppArmor security | |
4430 | frameworks with ConditionSecurity= has been added. | |
4431 | ||
4432 | * journalctl gained a new "-k" switch for showing only kernel | |
1fda0ab5 ZJS |
4433 | messages, mimicking dmesg output; in addition to "--user" |
4434 | and "--system" switches for showing only user's own logs | |
4435 | and system logs. | |
00aa832b LP |
4436 | |
4437 | * systemd-delta can now show information about drop-in | |
4438 | snippets extending unit files. | |
4439 | ||
4440 | * libsystemd-bus has been substantially updated but is still | |
4441 | not available as public API. | |
4442 | ||
4443 | * systemd will now look for the "debug" argument on the kernel | |
499b604b | 4444 | command line and enable debug logging, similar to what |
00aa832b LP |
4445 | "systemd.log_level=debug" already did before. |
4446 | ||
4447 | * "systemctl set-default", "systemctl get-default" has been | |
4448 | added to configure the default.target symlink, which | |
4449 | controls what to boot into by default. | |
4450 | ||
1fda0ab5 ZJS |
4451 | * "systemctl set-log-level" has been added as a convenient |
4452 | way to raise and lower systemd logging threshold. | |
4453 | ||
00aa832b LP |
4454 | * "systemd-analyze plot" will now show the time the various |
4455 | generators needed for execution, as well as information | |
4456 | about the unit file loading. | |
4457 | ||
00aa832b LP |
4458 | * libsystemd-journal gained a new sd_journal_open_files() call |
4459 | for opening specific journal files. journactl also gained a | |
4460 | new switch to expose this new functionality. Previously we | |
4461 | only supported opening all files from a directory, or all | |
4462 | files from the system, as opening individual files only is | |
4463 | racy due to journal file rotation. | |
4464 | ||
4465 | * systemd gained the new DefaultEnvironment= setting in | |
4466 | /etc/systemd/system.conf to set environment variables for | |
4467 | all services. | |
4468 | ||
4469 | * If a privileged process logs a journal message with the | |
4470 | OBJECT_PID= field set, then journald will automatically | |
4471 | augment this with additional OBJECT_UID=, OBJECT_GID=, | |
4472 | OBJECT_COMM=, OBJECT_EXE=, ... fields. This is useful if | |
4473 | system services want to log events about specific client | |
4474 | processes. journactl/systemctl has been updated to make use | |
4475 | of this information if all log messages regarding a specific | |
4476 | unit is requested. | |

4492 | CHANGES WITH 204: |

4494 | * The Python bindings gained some minimal support for the APIs | |
4495 | exposed by libsystemd-logind. | |
4496 | ||
4497 | * ConditionSecurity= gained support for detecting SMACK. Since | |
4498 | this condition already supports SELinux and AppArmor we only | |
4499 | miss IMA for this. Patches welcome! | |

2f3fcf85 LP |
4504 | CHANGES WITH 203: |
4505 | ||
4506 | * systemd-nspawn will now create /etc/resolv.conf if | |
4507 | necessary, before bind-mounting the host's file onto it. | |
4508 | ||
4509 | * systemd-nspawn will now store meta information about a | |
4510 | container on the container's cgroup as extended attribute | |
4511 | fields, including the root directory. | |
4512 | ||
4513 | * The cgroup hierarchy has been reworked in many ways. All | |
4514 | objects any of the components systemd creates in the cgroup | |
b82eed9a | 4515 | tree are now suffixed. More specifically, user sessions are |
2f3fcf85 LP |
4516 | now placed in cgroups suffixed with ".session", users in |
4517 | cgroups suffixed with ".user", and nspawn containers in | |
4518 | cgroups suffixed with ".nspawn". Furthermore, all cgroup | |
4519 | names are now escaped in a simple scheme to avoid collision | |
4520 | of userspace object names with kernel filenames. This work | |
4521 | is preparation for making these objects relocatable in the | |
4522 | cgroup tree, in order to allow easy resource partitioning of | |
4523 | these objects without causing naming conflicts. | |
4524 | ||
4525 | * systemctl list-dependencies gained the new switches | |
4526 | --plain, --reverse, --after and --before. | |
4527 | ||
4528 | * systemd-inhibit now shows the process name of processes that | |
4529 | have taken an inhibitor lock. | |
4530 | ||
4531 | * nss-myhostname will now also resolve "localhost" | |
4532 | implicitly. This makes /etc/hosts an optional file and | |
4533 | nicely handles that on IPv6 ::1 maps to both "localhost" and | |
4534 | the local hostname. | |
4535 | ||
4536 | * libsystemd-logind.so gained a new call | |
4537 | sd_get_machine_names() to enumerate running containers and | |
4538 | VMs (currently only supported by very new libvirt and | |
4539 | nspawn). sd_login_monitor can now be used to watch | |
4540 | VMs/containers coming and going. | |
4541 | ||
4542 | * .include is not allowed recursively anymore, and only in | |
4543 | unit files. Usually it is better to use drop-in snippets in | |
4544 | .d/*.conf anyway, as introduced with systemd 198. | |
4545 | ||
4546 | * systemd-analyze gained a new "critical-chain" command that | |
4547 | determines the slowest chain of units run during system | |
4548 | boot-up. It is very useful for tracking down where | |
4549 | optimizing boot time is the most beneficial. | |
4550 | ||
4551 | * systemd will no longer allow manipulating service paths in | |
4552 | the name=systemd:/system cgroup tree using ControlGroup= in | |
4553 | units. (But is still fine with it in all other dirs.) | |
4554 | ||
4555 | * There's a new systemd-nspawn@.service service file that may | |
4556 | be used to easily run nspawn containers as system | |
4557 | services. With the container's root directory in | |
4558 | /var/lib/container/foobar it is now sufficient to run | |
4559 | "systemctl start systemd-nspawn@foobar.service" to boot it. | |
4560 | ||
4561 | * systemd-cgls gained a new parameter "--machine" to list only | |
4562 | the processes within a certain container. | |
4563 | ||
4564 | * ConditionSecurity= now can check for "apparmor". We still | |
4565 | are lacking checks for SMACK and IMA for this condition | |
4566 | check though. Patches welcome! | |
4567 | ||
4568 | * A new configuration file /etc/systemd/sleep.conf has been | |
4569 | added that may be used to configure which kernel operation | |
4570 | systemd is supposed to execute when "suspend", "hibernate" | |
4571 | or "hybrid-sleep" is requested. This makes the new kernel | |
4572 | "freeze" state accessible to the user. | |
4573 | ||
4574 | * ENV{SYSTEMD_WANTS} in udev rules will now implicitly escape | |
4575 | the passed argument if applicable. | |

4586 | CHANGES WITH 202: |
4587 | ||
4588 | * The output of 'systemctl list-jobs' got some polishing. The | |
4589 | '--type=' argument may now be passed more than once. A new | |
4590 | command 'systemctl list-sockets' has been added which shows | |
4591 | a list of kernel sockets systemd is listening on with the | |
4592 | socket units they belong to, plus the units these socket | |
4593 | units activate. | |
4594 | ||
4595 | * The experimental libsystemd-bus library got substantial | |
4596 | updates to work in conjunction with the (also experimental) | |
4597 | kdbus kernel project. It works well enough to exchange | |
4598 | messages with some sophistication. Note that kdbus is not | |
4599 | ready yet, and the library is mostly an elaborate test case | |
4600 | for now, and not installable. | |
4601 | ||
4602 | * systemd gained a new unit 'systemd-static-nodes.service' | |
4603 | that generates static device nodes earlier during boot, and | |
4604 | can run in conjunction with udev. | |
4605 | ||
4606 | * libsystemd-login gained a new call sd_pid_get_user_unit() | |
4607 | to retrieve the user systemd unit a process is running | |
4608 | in. This is useful for systems where systemd is used as | |
4609 | session manager. | |
4610 | ||
4611 | * systemd-nspawn now places all containers in the new /machine | |
4612 | top-level cgroup directory in the name=systemd | |
4613 | hierarchy. libvirt will soon do the same, so that we get a | |
4614 | uniform separation of /system, /user and /machine for system | |
4615 | services, user processes and containers/virtual | |
4616 | machines. This new cgroup hierarchy is also useful to stick | |
4617 | stable names to specific container instances, which can be | |
7c04ad2d | 4618 | recognized later this way (this name may be controlled |
ef3b5246 LP |
4619 | via systemd-nspawn's new -M switch). libsystemd-login also |
4620 | gained a new call sd_pid_get_machine_name() to retrieve the | |
4621 | name of the container/VM a specific process belongs to. | |
4622 | ||
4623 | * bootchart can now store its data in the journal. | |
4624 | ||
4625 | * libsystemd-journal gained a new call | |
4626 | sd_journal_add_conjunction() for AND expressions to the | |
4627 | matching logic. This can be used to express more complex | |
4628 | logical expressions. | |
4629 | ||
4630 | * journactl can now take multiple --unit= and --user-unit= | |
4631 | switches. | |
4632 | ||
4633 | * The cryptsetup logic now understands the "luks.key=" kernel | |
4634 | command line switch for specifying a file to read the | |
7c04ad2d | 4635 | decryption key from. Also, if a configured key file is not |
ef3b5246 LP |
4636 | found the tool will now automatically fall back to prompting |
4637 | the user. | |
4638 | ||
cbeabcfb ZJS |
4639 | * Python systemd.journal module was updated to wrap recently |
4640 | added functions from libsystemd-journal. The interface was | |
4641 | changed to bring the low level interface in s.j._Reader | |
4642 | closer to the C API, and the high level interface in | |
4643 | s.j.Reader was updated to wrap and convert all data about | |
4644 | an entry. | |

d3a86981 LP |
4653 | CHANGES WITH 201: |
4654 | ||
4655 | * journalctl --update-catalog now understands a new --root= | |
4656 | option to operate on catalogs found in a different root | |
4657 | directory. | |
4658 | ||
4659 | * During shutdown after systemd has terminated all running | |
4660 | services a final killing loop kills all remaining left-over | |
4661 | processes. We will now print the name of these processes | |
4662 | when we send SIGKILL to them, since this usually indicates a | |
4663 | problem. | |
4664 | ||
4665 | * If /etc/crypttab refers to password files stored on | |
4666 | configured mount points automatic dependencies will now be | |
4667 | generated to ensure the specific mount is established first | |
4668 | before the key file is attempted to be read. | |
4669 | ||
4670 | * 'systemctl status' will now show information about the | |
4671 | network sockets a socket unit is listening on. | |
4672 | ||
4673 | * 'systemctl status' will also shown information about any | |
4674 | drop-in configuration file for units. (Drop-In configuration | |
4675 | files in this context are files such as | |
4676 | /etc/systemd/systemd/foobar.service.d/*.conf) | |
4677 | ||
4678 | * systemd-cgtop now optionally shows summed up CPU times of | |
4679 | cgroups. Press '%' while running cgtop to switch between | |
4680 | percentage and absolute mode. This is useful to determine | |
4681 | which cgroups use up the most CPU time over the entire | |
4682 | runtime of the system. systemd-cgtop has also been updated | |
4683 | to be 'pipeable' for processing with further shell tools. | |
4684 | ||
4685 | * 'hostnamectl set-hostname' will now allow setting of FQDN | |
4686 | hostnames. | |
4687 | ||
4688 | * The formatting and parsing of time span values has been | |
4689 | changed. The parser now understands fractional expressions | |
4690 | such as "5.5h". The formatter will now output fractional | |
4691 | expressions for all time spans under 1min, i.e. "5.123456s" | |
4692 | rather than "5s 123ms 456us". For time spans under 1s | |
4693 | millisecond values are shown, for those under 1ms | |
4694 | microsecond values are shown. This should greatly improve | |
4695 | all time-related output of systemd. | |
4696 | ||
4697 | * libsystemd-login and libsystemd-journal gained new | |
4698 | functions for querying the poll() events mask and poll() | |
4699 | timeout value for integration into arbitrary event | |
4700 | loops. | |
4701 | ||
4702 | * localectl gained the ability to list available X11 keymaps | |
4703 | (models, layouts, variants, options). | |
4704 | ||
4705 | * 'systemd-analyze dot' gained the ability to filter for | |
4706 | specific units via shell-style globs, to create smaller, | |
d28315e4 | 4707 | more useful graphs. I.e. it is now possible to create simple |
d3a86981 LP |
4708 | graphs of all the dependencies between only target units, or |
4709 | of all units that Avahi has dependencies with. | |

4719 | CHANGES WITH 200: |
4720 | ||
4721 | * The boot-time readahead implementation for rotating media | |
4722 | will now read the read-ahead data in multiple passes which | |
4723 | consist of all read requests made in equidistant time | |
4724 | intervals. This means instead of strictly reading read-ahead | |
4725 | data in its physical order on disk we now try to find a | |
4726 | middle ground between physical and access time order. | |
4727 | ||
4728 | * /etc/os-release files gained a new BUILD_ID= field for usage | |
4729 | on operating systems that provide continuous builds of OS | |
4730 | images. | |

4736 | CHANGES WITH 199: |
4737 | ||
4738 | * systemd-python gained an API exposing libsystemd-daemon. | |
4739 | ||
4740 | * The SMACK setup logic gained support for uploading CIPSO | |
4741 | security policy. | |
4742 | ||
4743 | * Behaviour of PrivateTmp=, ReadWriteDirectories=, | |
4744 | ReadOnlyDirectories= and InaccessibleDirectories= has | |
4745 | changed. The private /tmp and /var/tmp directories are now | |
4746 | shared by all processes of a service (which means | |
4747 | ExecStartPre= may now leave data in /tmp that ExecStart= of | |
4748 | the same service can still access). When a service is | |
4749 | stopped its temporary directories are immediately deleted | |
a87197f5 | 4750 | (normal clean-up with tmpfiles is still done in addition to |
35911459 LP |
4751 | this though). |
4752 | ||
4753 | * By default, systemd will now set a couple of sysctl | |
4754 | variables in the kernel: the safe sysrq options are turned | |
4755 | on, IP route verification is turned on, and source routing | |
4756 | disabled. The recently added hardlink and softlink | |
4757 | protection of the kernel is turned on. These settings should | |
4758 | be reasonably safe, and good defaults for all new systems. | |
4759 | ||
4760 | * The predictable network naming logic may now be turned off | |
a87197f5 | 4761 | with a new kernel command line switch: net.ifnames=0. |
35911459 LP |
4762 | |
4763 | * A new libsystemd-bus module has been added that implements a | |
4764 | pretty complete D-Bus client library. For details see: | |
4765 | ||
4766 | http://lists.freedesktop.org/archives/systemd-devel/2013-March/009797.html | |
4767 | ||
c20d8298 | 4768 | * journald will now explicitly flush the journal files to disk |
a87197f5 ZJS |
4769 | at the latest 5min after each write. The file will then also |
4770 | be marked offline until the next write. This should increase | |
4771 | reliability in case of a crash. The synchronization delay | |
4772 | can be configured via SyncIntervalSec= in journald.conf. | |
35911459 LP |
4773 | |
4774 | * There's a new remote-fs-setup.target unit that can be used | |
4775 | to pull in specific services when at least one remote file | |
4776 | system is to be mounted. | |
4777 | ||
4778 | * There are new targets timers.target and paths.target as | |
4779 | canonical targets to pull user timer and path units in | |
4780 | from. This complements sockets.target with a similar | |
4781 | purpose for socket units. | |
4782 | ||
6a7d3d68 LP |
4783 | * libudev gained a new call udev_device_set_attribute_value() |
4784 | to set sysfs attributes of a device. | |
4785 | ||
a87197f5 ZJS |
4786 | * The udev daemon now sets the default number of worker |
4787 | processes executed in parallel based on the number of available | |
c20d8298 | 4788 | CPUs instead of the amount of available RAM. This is supposed |
ab06eef8 | 4789 | to provide a more reliable default and limit a too aggressive |
c20d8298 KS |
4790 | paralellism for setups with 1000s of devices connected. |

85d68397 LP |
4802 | CHANGES WITH 198: |
4803 | ||
4804 | * Configuration of unit files may now be extended via drop-in | |
4805 | files without having to edit/override the unit files | |
4806 | themselves. More specifically, if the administrator wants to | |
4807 | change one value for a service file foobar.service he can | |
4808 | now do so by dropping in a configuration snippet into | |
ad88e758 | 4809 | /etc/systemd/system/foobar.service.d/*.conf. The unit logic |
85d68397 LP |
4810 | will load all these snippets and apply them on top of the |
4811 | main unit configuration file, possibly extending or | |
4812 | overriding its settings. Using these drop-in snippets is | |
40e21da8 KS |
4813 | generally nicer than the two earlier options for changing |
4814 | unit files locally: copying the files from | |
85d68397 LP |
4815 | /usr/lib/systemd/system/ to /etc/systemd/system/ and editing |
4816 | them there; or creating a new file in /etc/systemd/system/ | |
4817 | that incorporates the original one via ".include". Drop-in | |
4818 | snippets into these .d/ directories can be placed in any | |
fd868975 | 4819 | directory systemd looks for units in, and the usual |
85d68397 LP |
4820 | overriding semantics between /usr/lib, /etc and /run apply |
4821 | for them too. | |
4822 | ||
4823 | * Most unit file settings which take lists of items can now be | |
6aa8d43a | 4824 | reset by assigning the empty string to them. For example, |
85d68397 LP |
4825 | normally, settings such as Environment=FOO=BAR append a new |
4826 | environment variable assignment to the environment block, | |
4827 | each time they are used. By assigning Environment= the empty | |
4828 | string the environment block can be reset to empty. This is | |
4829 | particularly useful with the .d/*.conf drop-in snippets | |
156f7d09 KS |
4830 | mentioned above, since this adds the ability to reset list |
4831 | settings from vendor unit files via these drop-ins. | |
85d68397 LP |
4832 | |
4833 | * systemctl gained a new "list-dependencies" command for | |
4834 | listing the dependencies of a unit recursively. | |
4835 | ||
40e21da8 | 4836 | * Inhibitors are now honored and listed by "systemctl |
85d68397 LP |
4837 | suspend", "systemctl poweroff" (and similar) too, not only |
4838 | GNOME. These commands will also list active sessions by | |
4839 | other users. | |
4840 | ||
4841 | * Resource limits (as exposed by the various control group | |
4842 | controllers) can now be controlled dynamically at runtime | |
4843 | for all units. More specifically, you can now use a command | |
4844 | like "systemctl set-cgroup-attr foobar.service cpu.shares | |
4845 | 2000" to alter the CPU shares a specific service gets. These | |
6aa8d43a | 4846 | settings are stored persistently on disk, and thus allow the |
85d68397 LP |
4847 | administrator to easily adjust the resource usage of |
4848 | services with a few simple commands. This dynamic resource | |
6aa8d43a | 4849 | management logic is also available to other programs via the |
85d68397 LP |
4850 | bus. Almost any kernel cgroup attribute and controller is |
4851 | supported. | |
4852 | ||
4853 | * systemd-vconsole-setup will now copy all font settings to | |
6aa8d43a LP |
4854 | all allocated VTs, where it previously applied them only to |
4855 | the foreground VT. | |
85d68397 LP |
4856 | |
4857 | * libsystemd-login gained the new sd_session_get_tty() API | |
4858 | call. | |
4859 | ||
6aa8d43a LP |
4860 | * This release drops support for a few legacy or |
4861 | distribution-specific LSB facility names when parsing init | |
4862 | scripts: $x-display-manager, $mail-transfer-agent, | |
85d68397 LP |
4863 | $mail-transport-agent, $mail-transfer-agent, $smtp, |
4864 | $null. Also, the mail-transfer-agent.target unit backing | |
4865 | this has been removed. Distributions which want to retain | |
6aa8d43a LP |
4866 | compatibility with this should carry the burden for |
4867 | supporting this themselves and patch support for these back | |
4868 | in, if they really need to. Also, the facilities $syslog and | |
4869 | $local_fs are now ignored, since systemd does not support | |
4870 | early-boot LSB init scripts anymore, and these facilities | |
4871 | are implied anyway for normal services. syslog.target has | |
4872 | also been removed. | |
85d68397 | 4873 | |
40e21da8 | 4874 | * There are new bus calls on PID1's Manager object for |
6aa8d43a | 4875 | cancelling jobs, and removing snapshot units. Previously, |
85d68397 LP |
4876 | both calls were only available on the Job and Snapshot |
4877 | objects themselves. | |
4878 | ||
4879 | * systemd-journal-gatewayd gained SSL support. | |
4880 | ||
4881 | * The various "environment" files, such as /etc/locale.conf | |
4882 | now support continuation lines with a backslash ("\") as | |
499b604b | 4883 | last character in the line, similarly in style (but different) |
85d68397 LP |
4884 | to how this is supported in shells. |
4885 | ||
4886 | * For normal user processes the _SYSTEMD_USER_UNIT= field is | |
4887 | now implicitly appended to every log entry logged. systemctl | |
4888 | has been updated to filter by this field when operating on a | |
4889 | user systemd instance. | |
4890 | ||
4891 | * nspawn will now implicitly add the CAP_AUDIT_WRITE and | |
4892 | CAP_AUDIT_CONTROL capabilities to the capabilities set for | |
4893 | the container. This makes it easier to boot unmodified | |
4894 | Fedora systems in a container, which however still requires | |
4895 | audit=0 to be passed on the kernel command line. Auditing in | |
4896 | kernel and userspace is unfortunately still too broken in | |
4897 | context of containers, hence we recommend compiling it out | |
4898 | of the kernel or using audit=0. Hopefully this will be fixed | |
4899 | one day for good in the kernel. | |
4900 | ||
4901 | * nspawn gained the new --bind= and --bind-ro= parameters to | |
4902 | bind mount specific directories from the host into the | |
4903 | container. | |
4904 | ||
40e21da8 | 4905 | * nspawn will now mount its own devpts file system instance |
6aa8d43a | 4906 | into the container, in order not to leak pty devices from |
85d68397 LP |
4907 | the host into the container. |
4908 | ||
4909 | * systemd will now read the firmware boot time performance | |
6aa8d43a LP |
4910 | information from the EFI variables, if the used boot loader |
4911 | supports this, and takes it into account for boot performance | |
4912 | analysis via "systemd-analyze". This is currently supported | |
4913 | only in conjunction with Gummiboot, but could be supported | |
4914 | by other boot loaders too. For details see: | |

4918 | * A new generator has been added that automatically mounts the | |
4919 | EFI System Partition (ESP) to /boot, if that directory | |
6aa8d43a LP |
4920 | exists, is empty, and no other file system has been |
4921 | configured to be mounted there. | |
85d68397 LP |
4922 | |
4923 | * logind will now send out PrepareForSleep(false) out | |
4924 | unconditionally, after coming back from suspend. This may be | |
4925 | used by applications as asynchronous notification for | |
4926 | system resume events. | |
4927 | ||
4928 | * "systemctl unlock-sessions" has been added, that allows | |
4929 | unlocking the screens of all user sessions at once, similar | |
499b604b | 4930 | to how "systemctl lock-sessions" already locked all users |
40e21da8 | 4931 | sessions. This is backed by a new D-Bus call UnlockSessions(). |
85d68397 LP |
4932 | |
4933 | * "loginctl seat-status" will now show the master device of a | |
4934 | seat. (i.e. the device of a seat that needs to be around for | |
4935 | the seat to be considered available, usually the graphics | |
4936 | card). | |
4937 | ||
4938 | * tmpfiles gained a new "X" line type, that allows | |
4939 | configuration of files and directories (with wildcards) that | |
4940 | shall be excluded from automatic cleanup ("aging"). | |
4941 | ||
bf933560 KS |
4942 | * udev default rules set the device node permissions now only |
4943 | at "add" events, and do not change them any longer with a | |
4944 | later "change" event. | |
85d68397 LP |
4945 | |
4946 | * The log messages for lid events and power/sleep keypresses | |
4947 | now carry a message ID. | |
4948 | ||
4949 | * We now have a substantially larger unit test suite, but this | |
4950 | continues to be work in progress. | |
4951 | ||
4952 | * udevadm hwdb gained a new --root= parameter to change the | |
4953 | root directory to operate relative to. | |
4954 | ||
40e21da8 KS |
4955 | * logind will now issue a background sync() request to the kernel |
4956 | early at shutdown, so that dirty buffers are flushed to disk early | |
85d68397 LP |
4957 | instead of at the last moment, in order to optimize shutdown |
4958 | times a little. | |
4959 | ||
4960 | * A new bootctl tool has been added that is an interface for | |
4961 | certain boot loader operations. This is currently a preview | |
4962 | and is likely to be extended into a small mechanism daemon | |
4963 | like timedated, localed, hostnamed, and can be used by | |
4964 | graphical UIs to enumerate available boot options, and | |
4965 | request boot into firmware operations. | |
4966 | ||
4967 | * systemd-bootchart has been relicensed to LGPLv2.1+ to match | |
4968 | the rest of the package. It also has been updated to work | |
4969 | correctly in initrds. | |
4970 | ||
4971 | * Policykit previously has been runtime optional, and is now | |
4972 | also compile time optional via a configure switch. | |
4973 | ||
4974 | * systemd-analyze has been reimplemented in C. Also "systemctl | |
4975 | dot" has moved into systemd-analyze. | |
4976 | ||
4977 | * "systemctl status" with no further parameters will now print | |
4978 | the status of all active or failed units. | |
4979 | ||
4980 | * Operations such as "systemctl start" can now be executed | |
4981 | with a new mode "--irreversible" which may be used to queue | |
4982 | operations that cannot accidentally be reversed by a later | |
6aa8d43a | 4983 | job queuing. This is by default used to make shutdown |
85d68397 LP |
4984 | requests more robust. |
4985 | ||
4986 | * The Python API of systemd now gained a new module for | |
4987 | reading journal files. | |
4988 | ||
4989 | * A new tool kernel-install has been added that can install | |
4990 | kernel images according to the Boot Loader Specification: | |
4991 | ||
4992 | http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec | |
4993 | ||
4994 | * Boot time console output has been improved to provide | |
6aa8d43a | 4995 | animated boot time output for hanging jobs. |
85d68397 LP |
4996 | |
4997 | * A new tool systemd-activate has been added which can be used | |
4998 | to test socket activation with, directly from the command | |
4999 | line. This should make it much easier to test and debug | |
5000 | socket activation in daemons. | |
5001 | ||
5002 | * journalctl gained a new "--reverse" (or -r) option to show | |
5003 | journal output in reverse order (i.e. newest line first). | |
5004 | ||
43447fb7 LP |
5005 | * journalctl gained a new "--pager-end" (or -e) option to jump |
5006 | to immediately jump to the end of the journal in the | |
5007 | pager. This is only supported in conjunction with "less". | |
5008 | ||
85d68397 | 5009 | * journalctl gained a new "--user-unit=" option, that works |
499b604b | 5010 | similarly to "--unit=" but filters for user units rather than |
85d68397 LP |
5011 | system units. |
5012 | ||
5013 | * A number of unit files to ease adoption of systemd in | |
5014 | initrds has been added. This moves some minimal logic from | |
5015 | the various initrd implementations into systemd proper. | |
5016 | ||
5017 | * The journal files are now owned by a new group | |
5018 | "systemd-journal", which exists specifically to allow access | |
5019 | to the journal, and nothing else. Previously, we used the | |
6aa8d43a | 5020 | "adm" group for that, which however possibly covers more |
85d68397 LP |
5021 | than just journal/log file access. This new group is now |
5022 | already used by systemd-journal-gatewayd to ensure this | |
5023 | daemon gets access to the journal files and as little else | |
5024 | as possible. Note that "make install" will also set FS ACLs | |
5025 | up for /var/log/journal to give "adm" and "wheel" read | |
5026 | access to it, in addition to "systemd-journal" which owns | |
5027 | the journal files. We recommend that packaging scripts also | |
6aa8d43a | 5028 | add read access to "adm" + "wheel" to /var/log/journal, and |
85d68397 LP |
5029 | all existing/future journal files. To normal users and |
5030 | administrators little changes, however packagers need to | |
5031 | ensure to create the "systemd-journal" system group at | |
5032 | package installation time. | |
5033 | ||
5034 | * The systemd-journal-gatewayd now runs as unprivileged user | |
5035 | systemd-journal-gateway:systemd-journal-gateway. Packaging | |
5036 | scripts need to create these system user/group at | |
5037 | installation time. | |
5038 | ||
5039 | * timedated now exposes a new boolean property CanNTP that | |
5040 | indicates whether a local NTP service is available or not. | |
5041 | ||
5042 | * systemd-detect-virt will now also detect xen PVs | |
5043 | ||
40e21da8 KS |
5044 | * The pstore file system is now mounted by default, if it is |
5045 | available. | |
85d68397 | 5046 | |
1aed4590 LP |
5047 | * In addition to the SELinux and IMA policies we will now also |
5048 | load SMACK policies at early boot. | |

5065 | CHANGES WITH 197: |
5066 | ||
5067 | * Timer units now support calendar time events in addition to | |
5068 | monotonic time events. That means you can now trigger a unit | |
5069 | based on a calendar time specification such as "Thu,Fri | |
5070 | 2013-*-1,5 11:12:13" which refers to 11:12:13 of the first | |
5071 | or fifth day of any month of the year 2013, given that it is | |
5072 | a thursday or friday. This brings timer event support | |
5073 | considerably closer to cron's capabilities. For details on | |
5074 | the supported calendar time specification language see | |
5075 | systemd.time(7). | |
5076 | ||
5077 | * udev now supports a number of different naming policies for | |
5078 | network interfaces for predictable names, and a combination | |
5079 | of these policies is now the default. Please see this wiki | |
5080 | document for details: | |
5081 | ||
5082 | http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames | |
5083 | ||
5084 | * Auke Kok's bootchart implementation has been added to the | |
d28315e4 JE |
5085 | systemd tree. It is an optional component that can graph the |
5086 | boot in quite some detail. It is one of the best bootchart | |
8ad26859 LP |
5087 | implementations around and minimal in its code and |
5088 | dependencies. | |
5089 | ||
5090 | * nss-myhostname has been integrated into the systemd source | |
5091 | tree. nss-myhostname guarantees that the local hostname | |
5092 | always stays resolvable via NSS. It has been a weak | |
5093 | requirement of systemd-hostnamed since a long time, and | |
5094 | since its code is actually trivial we decided to just | |
5095 | include it in systemd's source tree. It can be turned off | |
5096 | with a configure switch. | |
5097 | ||
5098 | * The read-ahead logic is now capable of properly detecting | |
5099 | whether a btrfs file system is on SSD or rotating media, in | |
5100 | order to optimize the read-ahead scheme. Previously, it was | |
5101 | only capable of detecting this on traditional file systems | |
5102 | such as ext4. | |
5103 | ||
5104 | * In udev, additional device properties are now read from the | |
5105 | IAB in addition to the OUI database. Also, Bluetooth company | |
5106 | identities are attached to the devices as well. | |
5107 | ||
5108 | * In service files %U may be used as specifier that is | |
5109 | replaced by the configured user name of the service. | |
5110 | ||
5111 | * nspawn may now be invoked without a controlling TTY. This | |
5112 | makes it suitable for invocation as its own service. This | |
5113 | may be used to set up a simple containerized server system | |
5114 | using only core OS tools. | |
5115 | ||
5116 | * systemd and nspawn can now accept socket file descriptors | |
5117 | when they are started for socket activation. This enables | |
5118 | implementation of socket activated nspawn | |
5119 | containers. i.e. think about autospawning an entire OS image | |
5120 | when the first SSH or HTTP connection is received. We expect | |
5121 | that similar functionality will also be added to libvirt-lxc | |
5122 | eventually. | |
5123 | ||
5124 | * journalctl will now suppress ANSI color codes when | |
5125 | presenting log data. | |
5126 | ||
5127 | * systemctl will no longer show control group information for | |
5128 | a unit if a the control group is empty anyway. | |
5129 | ||
5130 | * logind can now automatically suspend/hibernate/shutdown the | |
5131 | system on idle. | |
5132 | ||
5133 | * /etc/machine-info and hostnamed now also expose the chassis | |
5134 | type of the system. This can be used to determine whether | |
5135 | the local system is a laptop, desktop, handset or | |
5136 | tablet. This information may either be configured by the | |
5137 | user/vendor or is automatically determined from ACPI and DMI | |
5138 | information if possible. | |
5139 | ||
5140 | * A number of PolicyKit actions are now bound together with | |
5141 | "imply" rules. This should simplify creating UIs because | |
5142 | many actions will now authenticate similar ones as well. | |
5143 | ||
5144 | * Unit files learnt a new condition ConditionACPower= which | |
5145 | may be used to conditionalize a unit depending on whether an | |
5146 | AC power source is connected or not, of whether the system | |
5147 | is running on battery power. | |
5148 | ||
5149 | * systemctl gained a new "is-failed" verb that may be used in | |
5150 | shell scripts and suchlike to check whether a specific unit | |
5151 | is in the "failed" state. | |
5152 | ||
5153 | * The EnvironmentFile= setting in unit files now supports file | |
5154 | globbing, and can hence be used to easily read a number of | |
5155 | environment files at once. | |
5156 | ||
5157 | * systemd will no longer detect and recognize specific | |
5158 | distributions. All distribution-specific #ifdeffery has been | |
5159 | removed, systemd is now fully generic and | |
5160 | distribution-agnostic. Effectively, not too much is lost as | |
5161 | a lot of the code is still accessible via explicit configure | |
5162 | switches. However, support for some distribution specific | |
5163 | legacy configuration file formats has been dropped. We | |
5164 | recommend distributions to simply adopt the configuration | |
5165 | files everybody else uses now and convert the old | |
5166 | configuration from packaging scripts. Most distributions | |
5167 | already did that. If that's not possible or desirable, | |
5168 | distributions are welcome to forward port the specific | |
5169 | pieces of code locally from the git history. | |
5170 | ||
5171 | * When logging a message about a unit systemd will now always | |
5172 | log the unit name in the message meta data. | |
5173 | ||
5174 | * localectl will now also discover system locale data that is | |
5175 | not stored in locale archives, but directly unpacked. | |
5176 | ||
5177 | * logind will no longer unconditionally use framebuffer | |
5178 | devices as seat masters, i.e. as devices that are required | |
5179 | to be existing before a seat is considered preset. Instead, | |
5180 | it will now look for all devices that are tagged as | |
b938cb90 JE |
5181 | "seat-master" in udev. By default, framebuffer devices will |
5182 | be marked as such, but depending on local systems, other | |
8ad26859 LP |
5183 | devices might be marked as well. This may be used to |
5184 | integrate graphics cards using closed source drivers (such | |
5185 | as NVidia ones) more nicely into logind. Note however, that | |
5186 | we recommend using the open source NVidia drivers instead, | |
5187 | and no udev rules for the closed-source drivers will be | |
5188 | shipped from us upstream. | |

5204 | CHANGES WITH 196: |
5205 | ||
5206 | * udev gained support for loading additional device properties | |
5207 | from an indexed database that is keyed by vendor/product IDs | |
5208 | and similar device identifiers. For the beginning this | |
5209 | "hwdb" is populated with data from the well-known PCI and | |
5210 | USB database, but also includes PNP, ACPI and OID data. In | |
5211 | the longer run this indexed database shall grow into | |
5212 | becoming the one central database for non-essential | |
5213 | userspace device metadata. Previously, data from the PCI/USB | |
96ec33c0 | 5214 | database was only attached to select devices, since the |
0428ddb7 | 5215 | lookup was a relatively expensive operation due to O(n) time |
96ec33c0 LP |
5216 | complexity (with n being the number of entries in the |
5217 | database). Since this is now O(1), we decided to add in this | |
5218 | data for all devices where this is available, by | |
0428ddb7 LP |
5219 | default. Note that the indexed database needs to be rebuilt |
5220 | when new data files are installed. To achieve this you need | |
5221 | to update your packaging scripts to invoke "udevadm hwdb | |
5222 | --update" after installation of hwdb data files. For | |
5223 | RPM-based distributions we introduced the new | |
5224 | %udev_hwdb_update macro for this purpose. | |
5225 | ||
5226 | * The Journal gained support for the "Message Catalog", an | |
5227 | indexed database to link up additional information with | |
5228 | journal entries. For further details please check: | |
5229 | ||
5230 | http://www.freedesktop.org/wiki/Software/systemd/catalog | |
5231 | ||
5232 | The indexed message catalog database also needs to be | |
5233 | rebuilt after installation of message catalog files. Use | |
5234 | "journalctl --update-catalog" for this. For RPM-based | |
5235 | distributions we introduced the %journal_catalog_update | |
5236 | macro for this purpose. | |
5237 | ||
5238 | * The Python Journal bindings gained support for the standard | |
5239 | Python logging framework. | |
5240 | ||
5241 | * The Journal API gained new functions for checking whether | |
5242 | the underlying file system of a journal file is capable of | |
5243 | properly reporting file change notifications, or whether | |
5244 | applications that want to reflect journal changes "live" | |
ab06eef8 | 5245 | need to recheck journal files continuously in appropriate |
0428ddb7 LP |
5246 | time intervals. |
5247 | ||
5248 | * It is now possible to set the "age" field for tmpfiles | |
5249 | entries to 0, indicating that files matching this entry | |
5250 | shall always be removed when the directories are cleaned up. | |
5251 | ||
5252 | * coredumpctl gained a new "gdb" verb which invokes gdb | |
5253 | right-away on the selected coredump. | |
5254 | ||
5255 | * There's now support for "hybrid sleep" on kernels that | |
5256 | support this, in addition to "suspend" and "hibernate". Use | |
5257 | "systemctl hybrid-sleep" to make use of this. | |
5258 | ||
5259 | * logind's HandleSuspendKey= setting (and related settings) | |
5260 | now gained support for a new "lock" setting to simply | |
5261 | request the screen lock on all local sessions, instead of | |
5262 | actually executing a suspend or hibernation. | |
5263 | ||
5264 | * systemd will now mount the EFI variables file system by | |
5265 | default. | |
5266 | ||
5267 | * Socket units now gained support for configuration of the | |
5268 | SMACK security label. | |
5269 | ||
5270 | * timedatectl will now output the time of the last and next | |
5271 | daylight saving change. | |
5272 | ||
5273 | * We dropped support for various legacy and distro-specific | |
5274 | concepts, such as insserv, early-boot SysV services | |
5275 | (i.e. those for non-standard runlevels such as 'b' or 'S') | |
5276 | or ArchLinux /etc/rc.conf support. We recommend the | |
5277 | distributions who still need support this to either continue | |
5278 | to maintain the necessary patches downstream, or find a | |
5279 | different solution. (Talk to us if you have questions!) | |
5280 | ||
5281 | * Various systemd components will now bypass PolicyKit checks | |
5282 | for root and otherwise handle properly if PolicyKit is not | |
5283 | found to be around. This should fix most issues for | |
5284 | PolicyKit-less systems. Quite frankly this should have been | |
5285 | this way since day one. It is absolutely our intention to | |
5286 | make systemd work fine on PolicyKit-less systems, and we | |
d28315e4 | 5287 | consider it a bug if something does not work as it should if |
0428ddb7 LP |
5288 | PolicyKit is not around. |
5289 | ||
5290 | * For embedded systems it is now possible to build udev and | |
5291 | systemd without blkid and/or kmod support. | |
5292 | ||
5293 | * "systemctl switch-root" is now capable of switching root | |
5294 | more than once. I.e. in addition to transitions from the | |
5295 | initrd to the host OS it is now possible to transition to | |
5296 | further OS images from the host. This is useful to implement | |
5297 | offline updating tools. | |
5298 | ||
5299 | * Various other additions have been made to the RPM macros | |
5300 | shipped with systemd. Use %udev_rules_update() after | |
5301 | installing new udev rules files. %_udevhwdbdir, | |
5302 | %_udevrulesdir, %_journalcatalogdir, %_tmpfilesdir, | |
5303 | %_sysctldir are now available which resolve to the right | |
5304 | directories for packages to place various data files in. | |
5305 | ||
5306 | * journalctl gained the new --full switch (in addition to | |
5307 | --all, to disable ellipsation for long messages. | |

5319 | CHANGES WITH 195: |
5320 | ||
6827101a | 5321 | * journalctl gained new --since= and --until= switches to |
139ee8cc LP |
5322 | filter by time. It also now supports nice filtering for |
5323 | units via --unit=/-u. | |
5324 | ||
6827101a | 5325 | * Type=oneshot services may use ExecReload= and do the |
139ee8cc LP |
5326 | right thing. |
5327 | ||
5328 | * The journal daemon now supports time-based rotation and | |
5329 | vacuuming, in addition to the usual disk-space based | |
5330 | rotation. | |
5331 | ||
5332 | * The journal will now index the available field values for | |
5333 | each field name. This enables clients to show pretty drop | |
5334 | downs of available match values when filtering. The bash | |
5335 | completion of journalctl has been updated | |
5336 | accordingly. journalctl gained a new switch -F to list all | |
5337 | values a certain field takes in the journal database. | |
5338 | ||
5339 | * More service events are now written as structured messages | |
5340 | to the journal, and made recognizable via message IDs. | |
5341 | ||
5342 | * The timedated, localed and hostnamed mini-services which | |
5343 | previously only provided support for changing time, locale | |
5344 | and hostname settings from graphical DEs such as GNOME now | |
5345 | also have a minimal (but very useful) text-based client | |
5346 | utility each. This is probably the nicest way to changing | |
5347 | these settings from the command line now, especially since | |
5348 | it lists available options and is fully integrated with bash | |
5349 | completion. | |
5350 | ||
5351 | * There's now a new tool "systemd-coredumpctl" to list and | |
5352 | extract coredumps from the journal. | |
5353 | ||
5354 | * We now install a README each in /var/log/ and | |
5355 | /etc/rc.d/init.d explaining where the system logs and init | |
5356 | scripts went. This hopefully should help folks who go to | |
5357 | that dirs and look into the otherwise now empty void and | |
5358 | scratch their heads. | |
5359 | ||
5360 | * When user-services are invoked (by systemd --user) the | |
5361 | $MANAGERPID env var is set to the PID of systemd. | |
5362 | ||
5363 | * SIGRTMIN+24 when sent to a --user instance will now result | |
5364 | in immediate termination of systemd. | |
5365 | ||
5366 | * gatewayd received numerous feature additions such as a | |
5367 | "follow" mode, for live syncing and filtering. | |
5368 | ||
5369 | * browse.html now allows filtering and showing detailed | |
5370 | information on specific entries. Keyboard navigation and | |
5371 | mouse screen support has been added. | |
5372 | ||
5373 | * gatewayd/journalctl now supports HTML5/JSON | |
5374 | Server-Sent-Events as output. | |
5375 | ||
1cb88f2c | 5376 | * The SysV init script compatibility logic will now |
139ee8cc LP |
5377 | heuristically determine whether a script supports the |
5378 | "reload" verb, and only then make this available as | |
5379 | "systemctl reload". | |
5380 | ||
15f47220 | 5381 | * "systemctl status --follow" has been removed, use "journalctl |
139ee8cc LP |
5382 | -u" instead. |
5383 | ||
5384 | * journald.conf's RuntimeMinSize=, PersistentMinSize= settings | |
5385 | have been removed since they are hardly useful to be | |
5386 | configured. | |
5387 | ||
5388 | * And I'd like to take the opportunity to specifically mention | |
5389 | Zbigniew for his great contributions. Zbigniew, you rock! | |

5399 | CHANGES WITH 194: |
5400 | ||
5401 | * If /etc/vconsole.conf is non-existent or empty we will no | |
5402 | longer load any console font or key map at boot by | |
5403 | default. Instead the kernel defaults will be left | |
5404 | intact. This is definitely the right thing to do, as no | |
5405 | configuration should mean no configuration, and hard-coding | |
5406 | font names that are different on all archs is probably a bad | |
5407 | idea. Also, the kernel default key map and font should be | |
5408 | good enough for most cases anyway, and mostly identical to | |
5409 | the userspace fonts/key maps we previously overloaded them | |
5410 | with. If distributions want to continue to default to a | |
5411 | non-kernel font or key map they should ship a default | |
5412 | /etc/vconsole.conf with the appropriate contents. | |

5418 | CHANGES WITH 193: |
5419 | ||
5420 | * journalctl gained a new --cursor= switch to show entries | |
5421 | starting from the specified location in the journal. | |
5422 | ||
5423 | * We now enforce a size limit on journal entry fields exported | |
5424 | with "-o json" in journalctl. Fields larger than 4K will be | |
5425 | assigned null. This can be turned off with --all. | |
5426 | ||
5427 | * An (optional) journal gateway daemon is now available as | |
5428 | "systemd-journal-gatewayd.service". This service provides | |
5429 | access to the journal via HTTP and JSON. This functionality | |
5430 | will be used to implement live log synchronization in both | |
5431 | pull and push modes, but has various other users too, such | |
5432 | as easy log access for debugging of embedded devices. Right | |
5433 | now it is already useful to retrieve the journal via HTTP: | |
5434 | ||
5435 | # systemctl start systemd-journal-gatewayd.service | |
5436 | # wget http://localhost:19531/entries | |
5437 | ||
5438 | This will download the journal contents in a | |
5439 | /var/log/messages compatible format. The same as JSON: | |
5440 | ||
5441 | # curl -H"Accept: application/json" http://localhost:19531/entries | |
5442 | ||
5443 | This service is also accessible via a web browser where a | |
5444 | single static HTML5 app is served that uses the JSON logic | |
5445 | to enable the user to do some basic browsing of the | |
5446 | journal. This will be extended later on. Here's an example | |
5447 | screenshot of this app in its current state: | |

5454 | CHANGES WITH 192: |
5455 | ||
5456 | * The bash completion logic is now available for journalctl | |
5457 | too. | |
5458 | ||
d28315e4 | 5459 | * We do not mount the "cpuset" controller anymore together with |
075d4ecb LP |
5460 | "cpu" and "cpuacct", as "cpuset" groups generally cannot be |
5461 | started if no parameters are assigned to it. "cpuset" hence | |
61233823 | 5462 | broke code that assumed it could create "cpu" groups and |
075d4ecb LP |
5463 | just start them. |
5464 | ||
5465 | * journalctl -f will now subscribe to terminal size changes, | |
5466 | and line break accordingly. | |

b6a86739 LP |
5471 | CHANGES WITH 191: |
5472 | ||
5473 | * nspawn will now create a symlink /etc/localtime in the | |
5474 | container environment, copying the host's timezone | |
5475 | setting. Previously this has been done via a bind mount, but | |
5476 | since symlinks cannot be bind mounted this has now been | |
5477 | changed to create/update the appropriate symlink. | |
5478 | ||
5479 | * journalctl -n's line number argument is now optional, and | |
5480 | will default to 10 if omitted. | |
5481 | ||
5482 | * journald will now log the maximum size the journal files may | |
5483 | take up on disk. This is particularly useful if the default | |
5484 | built-in logic of determining this parameter from the file | |
5485 | system size is used. Use "systemctl status | |
6563b535 | 5486 | systemd-journald.service" to see this information. |
b6a86739 LP |
5487 | |
5488 | * The multi-seat X wrapper tool has been stripped down. As X | |
5489 | is now capable of enumerating graphics devices via udev in a | |
5490 | seat-aware way the wrapper is not strictly necessary | |
5491 | anymore. A stripped down temporary stop-gap is still shipped | |
5492 | until the upstream display managers have been updated to | |
5493 | fully support the new X logic. Expect this wrapper to be | |
6563b535 | 5494 | removed entirely in one of the next releases. |
b6a86739 LP |
5495 | |
5496 | * HandleSleepKey= in logind.conf has been split up into | |
5497 | HandleSuspendKey= and HandleHibernateKey=. The old setting | |
6563b535 | 5498 | is not available anymore. X11 and the kernel are |
45afd519 | 5499 | distinguishing between these keys and we should too. This |
b6a86739 LP |
5500 | also means the inhibition lock for these keys has been split |
5501 | into two. | |

0c11f949 LP |
5506 | CHANGES WITH 190: |
5507 | ||
d28315e4 | 5508 | * Whenever a unit changes state we will now log this to the |
0c11f949 LP |
5509 | journal and show along the unit's own log output in |
5510 | "systemctl status". | |
5511 | ||
5512 | * ConditionPathIsMountPoint= can now properly detect bind | |
5513 | mount points too. (Previously, a bind mount of one file | |
8d0256b7 | 5514 | system to another place in the same file system could not be |
0c11f949 LP |
5515 | detected as mount, since they shared struct stat's st_dev |
5516 | field.) | |
5517 | ||
5518 | * We will now mount the cgroup controllers cpu, cpuacct, | |
5519 | cpuset and the controllers net_cls, net_prio together by | |
5520 | default. | |
5521 | ||
5522 | * nspawn containers will now have a virtualized boot | |
5523 | ID. (i.e. /proc/sys/kernel/random/boot_id is now mounted | |
5524 | over with a randomized ID at container initialization). This | |
5525 | has the effect of making "journalctl -b" do the right thing | |
5526 | in a container. | |
5527 | ||
5528 | * The JSON output journal serialization has been updated not | |
5529 | to generate "endless" list objects anymore, but rather one | |
5530 | JSON object per line. This is more in line how most JSON | |
5531 | parsers expect JSON objects. The new output mode | |
5532 | "json-pretty" has been added to provide similar output, but | |
5533 | neatly aligned for readability by humans. | |
5534 | ||
5535 | * We dropped all explicit sync() invocations in the shutdown | |
5536 | code. The kernel does this implicitly anyway in the kernel | |
5537 | reboot() syscall. halt(8)'s -n option is now a compatibility | |
5538 | no-op. | |
5539 | ||
5540 | * We now support virtualized reboot() in containers, as | |
5541 | supported by newer kernels. We will fall back to exit() if | |
5542 | CAP_SYS_REBOOT is not available to the container. Also, | |
5543 | nspawn makes use of this now and will actually reboot the | |
5544 | container if the containerized OS asks for that. | |
5545 | ||
5546 | * journalctl will only show local log output by default | |
5547 | now. Use --merge (-m) to show remote log output, too. | |
5548 | ||
5549 | * libsystemd-journal gained the new sd_journal_get_usage() | |
5550 | call to determine the current disk usage of all journal | |
5551 | files. This is exposed in the new "journalctl --disk-usage" | |
5552 | command. | |
5553 | ||
5554 | * journald gained a new configuration setting SplitMode= in | |
5555 | journald.conf which may be used to control how user journals | |
5556 | are split off. See journald.conf(5) for details. | |
5557 | ||
5558 | * A new condition type ConditionFileNotEmpty= has been added. | |
5559 | ||
5560 | * tmpfiles' "w" lines now support file globbing, to write | |
5561 | multiple files at once. | |
5562 | ||
5563 | * We added Python bindings for the journal submission | |
5564 | APIs. More Python APIs for a number of selected APIs will | |
5565 | likely follow. Note that we intend to add native bindings | |
5566 | only for the Python language, as we consider it common | |
5567 | enough to deserve bindings shipped within systemd. There are | |
5568 | various projects outside of systemd that provide bindings | |
5569 | for languages such as PHP or Lua. | |
5570 | ||
a98d5d64 LP |
5571 | * Many conditions will now resolve specifiers such as %i. In |
5572 | addition, PathChanged= and related directives of .path units | |
5573 | now support specifiers as well. | |
0c11f949 LP |
5574 | |
5575 | * There's now a new RPM macro definition for the system preset | |
5576 | dir: %_presetdir. | |
5577 | ||
d28315e4 | 5578 | * journald will now warn if it ca not forward a message to the |
dca348bc | 5579 | syslog daemon because its socket is full. |
0c11f949 LP |
5580 | |
5581 | * timedated will no longer write or process /etc/timezone, | |
5582 | except on Debian. As we do not support late mounted /usr | |
5583 | anymore /etc/localtime always being a symlink is now safe, | |
5584 | and hence the information in /etc/timezone is not necessary | |
5585 | anymore. | |
5586 | ||
aaccc32c | 5587 | * logind will now always reserve one VT for a text getty (VT6 |
0c11f949 LP |
5588 | by default). Previously if more than 6 X sessions where |
5589 | started they took up all the VTs with auto-spawned gettys, | |
5590 | so that no text gettys were available anymore. | |
5591 | ||
5592 | * udev will now automatically inform the btrfs kernel logic | |
5593 | about btrfs RAID components showing up. This should make | |
5594 | simple hotplug based btrfs RAID assembly work. | |
5595 | ||
5596 | * PID 1 will now increase its RLIMIT_NOFILE to 64K by default | |
5597 | (but not for its children which will stay at the kernel | |
5598 | default). This should allow setups with a lot more listening | |
5599 | sockets. | |
5600 | ||
5601 | * systemd will now always pass the configured timezone to the | |
5602 | kernel at boot. timedated will do the same when the timezone | |
5603 | is changed. | |
5604 | ||
5605 | * logind's inhibition logic has been updated. By default, | |
5606 | logind will now handle the lid switch, the power and sleep | |
5607 | keys all the time, even in graphical sessions. If DEs want | |
5608 | to handle these events on their own they should take the new | |
5609 | handle-power-key, handle-sleep-key and handle-lid-switch | |
f131770b | 5610 | inhibitors during their runtime. A simple way to achieve |
0c11f949 LP |
5611 | that is to invoke the DE wrapped in an invocation of: |
5612 | ||
5613 | systemd-inhibit --what=handle-power-key:handle-sleep-key:handle-lid-switch ... | |
5614 | ||
5615 | * Access to unit operations is now checked via SELinux taking | |
5616 | the unit file label and client process label into account. | |
5617 | ||
aad803af LP |
5618 | * systemd will now notify the administrator in the journal |
5619 | when he over-mounts a non-empty directory. | |
5620 | ||
5621 | * There are new specifiers that are resolved in unit files, | |
5622 | for the host name (%H), the machine ID (%m) and the boot ID | |
5623 | (%b). | |

38a60d71 LP |
5633 | CHANGES WITH 189: |
5634 | ||
5635 | * Support for reading structured kernel messages from | |
5636 | /dev/kmsg has now been added and is enabled by default. | |
5637 | ||
5638 | * Support for reading kernel messages from /proc/kmsg has now | |
5639 | been removed. If you want kernel messages in the journal | |
5640 | make sure to run a recent kernel (>= 3.5) that supports | |
5641 | reading structured messages from /dev/kmsg (see | |
5642 | above). /proc/kmsg is now exclusive property of classic | |
5643 | syslog daemons again. | |
5644 | ||
5645 | * The libudev API gained the new | |
5646 | udev_device_new_from_device_id() call. | |
5647 | ||
5648 | * The logic for file system namespace (ReadOnlyDirectory=, | |
5649 | ReadWriteDirectoy=, PrivateTmp=) has been reworked not to | |
5650 | require pivot_root() anymore. This means fewer temporary | |
5651 | directories are created below /tmp for this feature. | |
5652 | ||
5653 | * nspawn containers will now see and receive all submounts | |
5654 | made on the host OS below the root file system of the | |
5655 | container. | |
5656 | ||
5657 | * Forward Secure Sealing is now supported for Journal files, | |
5658 | which provide cryptographical sealing of journal files so | |
5659 | that attackers cannot alter log history anymore without this | |
5660 | being detectable. Lennart will soon post a blog story about | |
5661 | this explaining it in more detail. | |
5662 | ||
5663 | * There are two new service settings RestartPreventExitStatus= | |
5664 | and SuccessExitStatus= which allow configuration of exit | |
5665 | status (exit code or signal) which will be excepted from the | |
5666 | restart logic, resp. consider successful. | |
5667 | ||
5668 | * journalctl gained the new --verify switch that can be used | |
5669 | to check the integrity of the structure of journal files and | |
5670 | (if Forward Secure Sealing is enabled) the contents of | |
5671 | journal files. | |
5672 | ||
5673 | * nspawn containers will now be run with /dev/stdin, /dev/fd/ | |
5674 | and similar symlinks pre-created. This makes running shells | |
5675 | as container init process a lot more fun. | |
5676 | ||
5677 | * The fstab support can now handle PARTUUID= and PARTLABEL= | |
5678 | entries. | |
5679 | ||
5680 | * A new ConditionHost= condition has been added to match | |
5681 | against the hostname (with globs) and machine ID. This is | |
5682 | useful for clusters where a single OS image is used to | |
5683 | provision a large number of hosts which shall run slightly | |
5684 | different sets of services. | |
5685 | ||
5686 | * Services which hit the restart limit will now be placed in a | |
5687 | failure state. | |

5693 | CHANGES WITH 188: |
5694 | ||
5695 | * When running in --user mode systemd will now become a | |
5696 | subreaper (PR_SET_CHILD_SUBREAPER). This should make the ps | |
5697 | tree a lot more organized. | |
5698 | ||
5699 | * A new PartOf= unit dependency type has been introduced that | |
5700 | may be used to group services in a natural way. | |
5701 | ||
5702 | * "systemctl enable" may now be used to enable instances of | |
5703 | services. | |
5704 | ||
5705 | * journalctl now prints error log levels in red, and | |
5706 | warning/notice log levels in bright white. It also supports | |
5707 | filtering by log level now. | |
5708 | ||
5709 | * cgtop gained a new -n switch (similar to top), to configure | |
5710 | the maximum number of iterations to run for. It also gained | |
5711 | -b, to run in batch mode (accepting no input). | |
5712 | ||
ab06eef8 | 5713 | * The suffix ".service" may now be omitted on most systemctl |
c269cec3 LP |
5714 | command lines involving service unit names. |
5715 | ||
5716 | * There's a new bus call in logind to lock all sessions, as | |
5717 | well as a loginctl verb for it "lock-sessions". | |
5718 | ||
5719 | * libsystemd-logind.so gained a new call sd_journal_perror() | |
5720 | that works similar to libc perror() but logs to the journal | |
5721 | and encodes structured information about the error number. | |
5722 | ||
5723 | * /etc/crypttab entries now understand the new keyfile-size= | |
5724 | option. | |
5725 | ||
5726 | * shutdown(8) now can send a (configurable) wall message when | |
5727 | a shutdown is cancelled. | |
5728 | ||
5729 | * The mount propagation mode for the root file system will now | |
5730 | default to "shared", which is useful to make containers work | |
5731 | nicely out-of-the-box so that they receive new mounts from | |
5732 | the host. This can be undone locally by running "mount | |
5733 | --make-rprivate /" if needed. | |
5734 | ||
5735 | * The prefdm.service file has been removed. Distributions | |
5736 | should maintain this unit downstream if they intend to keep | |
5737 | it around. However, we recommend writing normal unit files | |
5738 | for display managers instead. | |
5739 | ||
5740 | * Since systemd is a crucial part of the OS we will now | |
5741 | default to a number of compiler switches that improve | |
5742 | security (hardening) such as read-only relocations, stack | |
5743 | protection, and suchlike. | |
5744 | ||
5745 | * The TimeoutSec= setting for services is now split into | |
5746 | TimeoutStartSec= and TimeoutStopSec= to allow configuration | |
5747 | of individual time outs for the start and the stop phase of | |
5748 | the service. | |

c4f1b862 LP |
5757 | CHANGES WITH 187: |
5758 | ||
5759 | * The journal and id128 C APIs are now fully documented as man | |
5760 | pages. | |
5761 | ||
5762 | * Extra safety checks have been added when transitioning from | |
5763 | the initial RAM disk to the main system to avoid accidental | |
5764 | data loss. | |
5765 | ||
c269cec3 | 5766 | * /etc/crypttab entries now understand the new keyfile-offset= |
c4f1b862 LP |
5767 | option. |
5768 | ||
5769 | * systemctl -t can now be used to filter by unit load state. | |
5770 | ||
5771 | * The journal C API gained the new sd_journal_wait() call to | |
5772 | make writing synchronous journal clients easier. | |
5773 | ||
5774 | * journalctl gained the new -D switch to show journals from a | |
5775 | specific directory. | |
5776 | ||
5777 | * journalctl now displays a special marker between log | |
5778 | messages of two different boots. | |
5779 | ||
5780 | * The journal is now explicitly flushed to /var via a service | |
5781 | systemd-journal-flush.service, rather than implicitly simply | |
5782 | by seeing /var/log/journal to be writable. | |
5783 | ||
5784 | * journalctl (and the journal C APIs) can now match for much | |
5785 | more complex expressions, with alternatives and | |
5786 | disjunctions. | |
5787 | ||
5788 | * When transitioning from the initial RAM disk to the main | |
5789 | system we will now kill all processes in a killing spree to | |
5790 | ensure no processes stay around by accident. | |
5791 | ||
5792 | * Three new specifiers may be used in unit files: %u, %h, %s | |
5793 | resolve to the user name, user home directory resp. user | |
5794 | shell. This is useful for running systemd user instances. | |
5795 | ||
5796 | * We now automatically rotate journal files if their data | |
5797 | object hash table gets a fill level > 75%. We also size the | |
5798 | hash table based on the configured maximum file size. This | |
5799 | together should lower hash collisions drastically and thus | |
5800 | speed things up a bit. | |
5801 | ||
5802 | * journalctl gained the new "--header" switch to introspect | |
5803 | header data of journal files. | |
5804 | ||
5805 | * A new setting SystemCallFilters= has been added to services | |
5806 | which may be used to apply blacklists or whitelists to | |
5807 | system calls. This is based on SECCOMP Mode 2 of Linux 3.5. | |
5808 | ||
5809 | * nspawn gained a new --link-journal= switch (and quicker: -j) | |
5810 | to link the container journal with the host. This makes it | |
5811 | very easy to centralize log viewing on the host for all | |
5812 | guests while still keeping the journal files separated. | |
5813 | ||
5814 | * Many bugfixes and optimizations | |

b5b4c94a LP |
5821 | CHANGES WITH 186: |
5822 | ||
5823 | * Several tools now understand kernel command line arguments, | |
5824 | which are only read when run in an initial RAM disk. They | |
5825 | usually follow closely their normal counterparts, but are | |
5826 | prefixed with rd. | |
5827 | ||
5828 | * There's a new tool to analyze the readahead files that are | |
5829 | automatically generated at boot. Use: | |
5830 | ||
5831 | /usr/lib/systemd/systemd-readahead analyze /.readahead | |
5832 | ||
5833 | * We now provide an early debug shell on tty9 if this enabled. Use: | |
5834 | ||
d1f9edaf | 5835 | systemctl enable debug-shell.service |
b5b4c94a LP |
5836 | |
5837 | * All plymouth related units have been moved into the Plymouth | |
5838 | package. Please make sure to upgrade your Plymouth version | |
5839 | as well. | |
5840 | ||
5841 | * systemd-tmpfiles now supports getting passed the basename of | |
5842 | a configuration file only, in which case it will look for it | |
5843 | in all appropriate directories automatically. | |
5844 | ||
5845 | * udevadm info now takes a /dev or /sys path as argument, and | |
5846 | does the right thing. Example: | |
5847 | ||
5848 | udevadm info /dev/sda | |
5849 | udevadm info /sys/class/block/sda | |
5850 | ||
5851 | * systemctl now prints a warning if a unit is stopped but a | |
5852 | unit that might trigger it continues to run. Example: a | |
5853 | service is stopped but the socket that activates it is left | |
5854 | running. | |
5855 | ||
5856 | * "systemctl status" will now mention if the log output was | |
5857 | shortened due to rotation since a service has been started. | |
5858 | ||
5859 | * The journal API now exposes functions to determine the | |
5860 | "cutoff" times due to rotation. | |
5861 | ||
5862 | * journald now understands SIGUSR1 and SIGUSR2 for triggering | |
5863 | immediately flushing of runtime logs to /var if possible, | |
5864 | resp. for triggering immediate rotation of the journal | |
5865 | files. | |
5866 | ||
5867 | * It is now considered an error if a service is attempted to | |
5868 | be stopped that is not loaded. | |
5869 | ||
5870 | * XDG_RUNTIME_DIR now uses numeric UIDs instead of usernames. | |
5871 | ||
5872 | * systemd-analyze now supports Python 3 | |
5873 | ||
5874 | * tmpfiles now supports cleaning up directories via aging | |
5875 | where the first level dirs are always kept around but | |
5876 | directories beneath it automatically aged. This is enabled | |
5877 | by prefixing the age field with '~'. | |
5878 | ||
5879 | * Seat objects now expose CanGraphical, CanTTY properties | |
5880 | which is required to deal with very fast bootups where the | |
5881 | display manager might be running before the graphics drivers | |
5882 | completed initialization. | |
5883 | ||
5884 | * Seat objects now expose a State property. | |
5885 | ||
5886 | * We now include RPM macros for service enabling/disabling | |
5887 | based on the preset logic. We recommend RPM based | |
5888 | distributions to make use of these macros if possible. This | |
5889 | makes it simpler to reuse RPM spec files across | |
5890 | distributions. | |
5891 | ||
5892 | * We now make sure that the collected systemd unit name is | |
5893 | always valid when services log to the journal via | |
5894 | STDOUT/STDERR. | |
5895 | ||
5896 | * There's a new man page kernel-command-line(7) detailing all | |
5897 | command line options we understand. | |
5898 | ||
5899 | * The fstab generator may now be disabled at boot by passing | |
5900 | fstab=0 on the kernel command line. | |
5901 | ||
91ac7425 | 5902 | * A new kernel command line option modules-load= is now understood |
b5b4c94a LP |
5903 | to load a specific kernel module statically, early at boot. |
5904 | ||
5905 | * Unit names specified on the systemctl command line are now | |
5906 | automatically escaped as needed. Also, if file system or | |
5907 | device paths are specified they are automatically turned | |
5908 | into the appropriate mount or device unit names. Example: | |
5909 | ||
5910 | systemctl status /home | |
5911 | systemctl status /dev/sda | |
5912 | ||
5913 | * The SysVConsole= configuration option has been removed from | |
5914 | system.conf parsing. | |
5915 | ||
5916 | * The SysV search path is no longer exported on the D-Bus | |
5917 | Manager object. | |
5918 | ||
5919 | * The Names= option is been removed from unit file parsing. | |
5920 | ||
5921 | * There's a new man page bootup(7) detailing the boot process. | |
5922 | ||
5923 | * Every unit and every generator we ship with systemd now | |
5924 | comes with full documentation. The self-explanatory boot is | |
5925 | complete. | |
5926 | ||
5927 | * A couple of services gained "systemd-" prefixes in their | |
5928 | name if they wrap systemd code, rather than only external | |
5929 | code. Among them fsck@.service which is now | |
5930 | systemd-fsck@.service. | |
5931 | ||
5932 | * The HaveWatchdog property has been removed from the D-Bus | |
5933 | Manager object. | |
5934 | ||
5935 | * systemd.confirm_spawn= on the kernel command line should now | |
5936 | work sensibly. | |
5937 | ||
5938 | * There's a new man page crypttab(5) which details all options | |
5939 | we actually understand. | |
5940 | ||
5941 | * systemd-nspawn gained a new --capability= switch to pass | |
5942 | additional capabilities to the container. | |
5943 | ||
5944 | * timedated will now read known NTP implementation unit names | |
5b00c016 | 5945 | from /usr/lib/systemd/ntp-units.d/*.list, |
b5b4c94a LP |
5946 | systemd-timedated-ntp.target has been removed. |
5947 | ||
5948 | * journalctl gained a new switch "-b" that lists log data of | |
5949 | the current boot only. | |
5950 | ||
5951 | * The notify socket is in the abstract namespace again, in | |
5952 | order to support daemons which chroot() at start-up. | |
5953 | ||
5954 | * There is a new Storage= configuration option for journald | |
5955 | which allows configuration of where log data should go. This | |
5956 | also provides a way to disable journal logging entirely, so | |
5957 | that data collected is only forwarded to the console, the | |
5958 | kernel log buffer or another syslog implementation. | |
5959 | ||
c4f1b862 | 5960 | * Many bugfixes and optimizations |

5969 | * "systemctl help <unit>" now shows the man page if one is |
5970 | available. | |
5971 | ||
5972 | * Several new man pages have been added. | |
5973 | ||
b5b4c94a LP |
5974 | * MaxLevelStore=, MaxLevelSyslog=, MaxLevelKMsg=, |
5975 | MaxLevelConsole= can now be specified in | |
5976 | journald.conf. These options allow reducing the amount of | |
5977 | data stored on disk or forwarded by the log level. | |
2d197285 | 5978 | |
b5b4c94a LP |
5979 | * TimerSlackNSec= can now be specified in system.conf for |

b6a86739 | 5987 | |
4c8cd173 LP |
5988 | * logind is now capable of (optionally) handling power and |
5989 | sleep keys as well as the lid switch. | |
5990 | ||
5991 | * journalctl now understands the syntax "journalctl | |
5992 | /usr/bin/avahi-daemon" to get all log output of a specific | |
5993 | daemon. | |
5994 | ||
5995 | * CapabilityBoundingSet= in system.conf now also influences | |
5996 | the capability bound set of usermode helpers of the kernel. | |

ea5943d3 | 6003 | CHANGES WITH 183: |
b6a86739 | 6004 | |
187076d4 LP |
6005 | * Note that we skipped 139 releases here in order to set the |
6006 | new version to something that is greater than both udev's | |
6007 | and systemd's most recent version number. | |
6008 | ||
194bbe33 KS |
6009 | * udev: all udev sources are merged into the systemd source tree now. |
6010 | All future udev development will happen in the systemd tree. It | |
6011 | is still fully supported to use the udev daemon and tools without | |
6012 | systemd running, like in initramfs or other init systems. Building | |
6013 | udev though, will require the *build* of the systemd tree, but | |
ea5943d3 | 6014 | udev can be properly *run* without systemd. |
07cd4fc1 | 6015 | |
91cf7e5c | 6016 | * udev: /lib/udev/devices/ are not read anymore; systemd-tmpfiles |
f13b388f KS |
6017 | should be used to create dead device nodes as workarounds for broken |
6018 | subsystems. | |
64661ee7 | 6019 | |
2d13da88 KS |
6020 | * udev: RUN+="socket:..." and udev_monitor_new_from_socket() is |
6021 | no longer supported. udev_monitor_new_from_netlink() needs to be | |
6022 | used to subscribe to events. | |
6023 | ||
194bbe33 KS |
6024 | * udev: when udevd is started by systemd, processes which are left |
6025 | behind by forking them off of udev rules, are unconditionally cleaned | |
6026 | up and killed now after the event handling has finished. Services or | |
6027 | daemons must be started as systemd services. Services can be | |
ea5943d3 | 6028 | pulled-in by udev to get started, but they can no longer be directly |
194bbe33 KS |
6029 | forked by udev rules. |
6030 | ||
f13b388f KS |
6031 | * udev: the daemon binary is called systemd-udevd now and installed |
6032 | in /usr/lib/systemd/. Standalone builds or non-systemd systems need | |
6033 | to adapt to that, create symlink, or rename the binary after building | |
6034 | it. | |
6035 | ||
ea5943d3 | 6036 | * libudev no longer provides these symbols: |
c1959569 KS |
6037 | udev_monitor_from_socket() |
6038 | udev_queue_get_failed_list_entry() | |
6039 | udev_get_{dev,sys,run}_path() | |
ea5943d3 | 6040 | The versions number was bumped and symbol versioning introduced. |
c1959569 | 6041 | |
ea5943d3 | 6042 | * systemd-loginctl and systemd-journalctl have been renamed |
9ae9afce | 6043 | to loginctl and journalctl to match systemctl. |
18b754d3 KS |
6044 | |
6045 | * The config files: /etc/systemd/systemd-logind.conf and | |
6046 | /etc/systemd/systemd-journald.conf have been renamed to | |
6047 | logind.conf and journald.conf. Package updates should rename | |
6048 | the files to the new names on upgrade. | |
6049 | ||
ea5943d3 LP |
6050 | * For almost all files the license is now LGPL2.1+, changed |
6051 | from the previous GPL2.0+. Exceptions are some minor stuff | |
6052 | of udev (which will be changed to LGPL2.1 eventually, too), | |
6053 | and the MIT licensed sd-daemon.[ch] library that is suitable | |
6054 | to be used as drop-in files. | |
6055 | ||
6056 | * systemd and logind now handle system sleep states, in | |
49f43d5f | 6057 | particular suspending and hibernating. |
ea5943d3 LP |
6058 | |
6059 | * logind now implements a sleep/shutdown/idle inhibiting logic | |
6060 | suitable for a variety of uses. Soonishly Lennart will blog | |
6061 | about this in more detail. | |
6062 | ||
6063 | * var-run.mount and var-lock.mount are no longer provided | |
6064 | (which prevously bind mounted these directories to their new | |
6065 | places). Distributions which have not converted these | |
6066 | directories to symlinks should consider stealing these files | |
6067 | from git history and add them downstream. | |
6068 | ||
6069 | * We introduced the Documentation= field for units and added | |
6070 | this to all our shipped units. This is useful to make it | |
3943231c | 6071 | easier to explore the boot and the purpose of the various |
ea5943d3 LP |
6072 | units. |
6073 | ||
6074 | * All smaller setup units (such as | |
6075 | systemd-vconsole-setup.service) now detect properly if they | |
6076 | are run in a container and are skipped when | |
6077 | appropriate. This guarantees an entirely noise-free boot in | |
6078 | Linux container environments such as systemd-nspawn. | |
6079 | ||
6080 | * A framework for implementing offline system updates is now | |
6081 | integrated, for details see: | |
6082 | http://freedesktop.org/wiki/Software/systemd/SystemUpdates | |
6083 | ||
6084 | * A new service type Type=idle is available now which helps us | |
6085 | avoiding ugly interleaving of getty output and boot status | |
6086 | messages. | |
6087 | ||
439d6dfd LP |
6088 | * There's now a system-wide CapabilityBoundingSet= option to |
6089 | globally reduce the set of capabilities for the | |
ea5943d3 LP |
6090 | system. This is useful to drop CAP_SYS_MKNOD, CAP_SYS_RAWIO, |
6091 | CAP_NET_RAW, CAP_SYS_MODULE, CAP_SYS_TIME, CAP_SYS_PTRACE or | |
6092 | even CAP_NET_ADMIN system-wide for secure systems. | |
6093 | ||
6094 | * There are now system-wide DefaultLimitXXX= options to | |
6095 | globally change the defaults of the various resource limits | |
6096 | for all units started by PID 1. | |
6097 | ||
6098 | * Harald Hoyer's systemd test suite has been integrated into | |
6099 | systemd which allows easy testing of systemd builds in qemu | |
6100 | and nspawn. (This is really awesome! Ask us for details!) | |
6101 | ||
3943231c LP |
6102 | * The fstab parser is now implemented as generator, not inside |
6103 | of PID 1 anymore. | |
ea5943d3 LP |
6104 | |
6105 | * systemctl will now warn you if .mount units generated from | |
6106 | /etc/fstab are out of date due to changes in fstab that | |
d28315e4 | 6107 | have not been read by systemd yet. |
ea5943d3 LP |
6108 | |
6109 | * systemd is now suitable for usage in initrds. Dracut has | |
6110 | already been updated to make use of this. With this in place | |
6111 | initrds get a slight bit faster but primarily are much | |
6112 | easier to introspect and debug since "systemctl status" in | |
6113 | the host system can be used to introspect initrd services, | |
6114 | and the journal from the initrd is kept around too. | |
6115 | ||
6116 | * systemd-delta has been added, a tool to explore differences | |
6117 | between user/admin configuration and vendor defaults. | |
6118 | ||
6119 | * PrivateTmp= now affects both /tmp and /var/tmp. | |
6120 | ||
6121 | * Boot time status messages are now much prettier and feature | |
6122 | proper english language. Booting up systemd has never been | |
6123 | so sexy. | |
6124 | ||
6125 | * Read-ahead pack files now include the inode number of all | |
6126 | files to pre-cache. When the inode changes the pre-caching | |
6127 | is not attempted. This should be nicer to deal with updated | |
6128 | packages which might result in changes of read-ahead | |
6129 | patterns. | |
6130 | ||
6131 | * We now temporaritly lower the kernel's read_ahead_kb variable | |
6132 | when collecting read-ahead data to ensure the kernel's | |
6133 | built-in read-ahead does not add noise to our measurements | |
6134 | of necessary blocks to pre-cache. | |
6135 | ||
6136 | * There's now RequiresMountsFor= to add automatic dependencies | |
6137 | for all mounts necessary for a specific file system path. | |
6138 | ||
6139 | * MountAuto= and SwapAuto= have been removed from | |
6140 | system.conf. Mounting file systems at boot has to take place | |
6141 | in systemd now. | |
6142 | ||
6143 | * nspawn now learned a new switch --uuid= to set the machine | |
6144 | ID on the command line. | |
6145 | ||
f8c0a2cb | 6146 | * nspawn now learned the -b switch to automatically search |
ea5943d3 LP |
6147 | for an init system. |
6148 | ||
6149 | * vt102 is now the default TERM for serial TTYs, upgraded from | |
6150 | vt100. | |
6151 | ||
6152 | * systemd-logind now works on VT-less systems. | |
6153 | ||
6154 | * The build tree has been reorganized. The individual | |
3943231c | 6155 | components now have directories of their own. |
ea5943d3 LP |
6156 | |
6157 | * A new condition type ConditionPathIsReadWrite= is now available. | |
6158 | ||
6159 | * nspawn learned the new -C switch to create cgroups for the | |
6160 | container in other hierarchies. | |
6161 | ||
6162 | * We now have support for hardware watchdogs, configurable in | |
6163 | system.conf. | |
6164 | ||
6165 | * The scheduled shutdown logic now has a public API. | |
6166 | ||
6167 | * We now mount /tmp as tmpfs by default, but this can be | |
6168 | masked and /etc/fstab can override it. | |
6169 | ||
d28315e4 | 6170 | * Since udisks does not make use of /media anymore we are not |
ea5943d3 LP |
6171 | mounting a tmpfs on it anymore. |
6172 | ||
6173 | * journalctl gained a new --local switch to only interleave | |
6174 | locally generated journal files. | |
6175 | ||
6176 | * We can now load the IMA policy at boot automatically. | |
6177 | ||
6178 | * The GTK tools have been split off into a systemd-ui. | |

16f1239e | 6191 | CHANGES WITH 44: |
b6a86739 | 6192 | |
16f1239e LP |
6193 | * This is mostly a bugfix release |
6194 | ||
6195 | * Support optional initialization of the machine ID from the | |
6196 | KVM or container configured UUID. | |
6197 | ||
6198 | * Support immediate reboots with "systemctl reboot -ff" | |
6199 | ||
6200 | * Show /etc/os-release data in systemd-analyze output | |
6201 | ||
ab06eef8 | 6202 | * Many bugfixes for the journal, including endianness fixes and |
16f1239e LP |
6203 | ensuring that disk space enforcement works |
6204 | ||
6205 | * sd-login.h is C++ comptaible again | |
6206 | ||
6207 | * Extend the /etc/os-release format on request of the Debian | |
6208 | folks | |
6209 | ||
6210 | * We now refuse non-UTF8 strings used in various configuration | |
d28315e4 | 6211 | and unit files. This is done to ensure we do not pass invalid |
16f1239e LP |
6212 | data over D-Bus or expose it elsewhere. |
6213 | ||
6214 | * Register Mimo USB Screens as suitable for automatic seat | |
6215 | configuration | |
6216 | ||
6217 | * Read SELinux client context from journal clients in a race | |
6218 | free fashion | |
6219 | ||
6220 | * Reorder configuration file lookup order. /etc now always | |
6221 | overrides /run in order to allow the administrator to always | |
b938cb90 | 6222 | and unconditionally override vendor-supplied or |
16f1239e LP |
6223 | automatically generated data. |
6224 | ||
6225 | * The various user visible bits of the journal now have man | |
6226 | pages. We still lack man pages for the journal API calls | |
6227 | however. | |
6228 | ||
6229 | * We now ship all man pages in HTML format again in the | |
6230 | tarball. | |

b6a86739 | 6238 | |
437b7dee LP |
6239 | * This is mostly a bugfix release |
6240 | ||
6241 | * systems lacking /etc/os-release are no longer supported. | |
6242 | ||
6243 | * Various functionality updates to libsystemd-login.so | |
6244 | ||
45afd519 | 6245 | * Track class of PAM logins to distinguish greeters from |
437b7dee LP |
6246 | normal user logins. |

b6a86739 | 6252 | |
204fa33c LP |
6253 | * This is an important bugfix release for v41. |
6254 | ||
6255 | * Building man pages is now optional which should be useful | |
6256 | for those building systemd from git but unwilling to install | |
6257 | xsltproc. | |
6258 | ||
6259 | * Watchdog support for supervising services is now usable. In | |
6260 | a future release support for hardware watchdogs | |
6261 | (i.e. /dev/watchdog) will be added building on this. | |
6262 | ||
6263 | * Service start rate limiting is now configurable and can be | |
6264 | turned off per service. When a start rate limit is hit a | |
6265 | reboot can automatically be triggered. | |
6266 | ||
6267 | * New CanReboot(), CanPowerOff() bus calls in systemd-logind. | |

e0d25329 | 6273 | CHANGES WITH 41: |
b6a86739 | 6274 | |
e0d25329 KS |
6275 | * The systemd binary is installed /usr/lib/systemd/systemd now; |
6276 | An existing /sbin/init symlink needs to be adapted with the | |
6277 | package update. | |
6278 | ||
b13df964 LP |
6279 | * The code that loads kernel modules has been ported to invoke |
6280 | libkmod directly, instead of modprobe. This means we do not | |
6281 | support systems with module-init-tools anymore. | |
6282 | ||
6283 | * Watchdog support is now already useful, but still not | |
6284 | complete. | |
6285 | ||
6286 | * A new kernel command line option systemd.setenv= is | |
6287 | understood to set system wide environment variables | |
6288 | dynamically at boot. | |
6289 | ||
e9c1ea9d | 6290 | * We now limit the set of capabilities of systemd-journald. |
ccd07a08 | 6291 | |
353e12c2 LP |
6292 | * We now set SIGPIPE to ignore by default, since it only is |
6293 | useful in shell pipelines, and has little use in general | |
6294 | code. This can be disabled with IgnoreSIPIPE=no in unit | |
6295 | files. | |

d26e4270 | 6301 | CHANGES WITH 40: |
b6a86739 | 6302 | |
d26e4270 LP |
6303 | * This is mostly a bugfix release |
6304 | ||
6305 | * We now expose the reason why a service failed in the | |
6306 | "Result" D-Bus property. | |
6307 | ||
6308 | * Rudimentary service watchdog support (will be completed over | |
6309 | the next few releases.) | |
6310 | ||
6311 | * When systemd forks off in order execute some service we will | |
6312 | now immediately changes its argv[0] to reflect which process | |
6313 | it will execute. This is useful to minimize the time window | |
6314 | with a generic argv[0], which makes bootcharts more useful | |

220a21d3 | 6320 | CHANGES WITH 39: |
b6a86739 | 6321 | |
220a21d3 LP |
6322 | * This is mostly a test release, but incorporates many |
6323 | bugfixes. | |
6324 | ||
6325 | * New systemd-cgtop tool to show control groups by their | |
6326 | resource usage. | |
6327 | ||
6328 | * Linking against libacl for ACLs is optional again. If | |
6329 | disabled, support tracking device access for active logins | |
6330 | goes becomes unavailable, and so does access to the user | |
6331 | journals by the respective users. | |
6332 | ||
6333 | * If a group "adm" exists, journal files are automatically | |
6334 | owned by them, thus allow members of this group full access | |
6335 | to the system journal as well as all user journals. | |
6336 | ||
6337 | * The journal now stores the SELinux context of the logging | |
6338 | client for all entries. | |
6339 | ||
6340 | * Add C++ inclusion guards to all public headers | |
6341 | ||
6342 | * New output mode "cat" in the journal to print only text | |
6343 | messages, without any meta data like date or time. | |
6344 | ||
6345 | * Include tiny X server wrapper as a temporary stop-gap to | |
6346 | teach XOrg udev display enumeration. This is used by display | |
6347 | managers such as gdm, and will go away as soon as XOrg | |
6348 | learned native udev hotplugging for display devices. | |
6349 | ||
6350 | * Add new systemd-cat tool for executing arbitrary programs | |
6351 | with STDERR/STDOUT connected to the journal. Can also act as | |
6352 | BSD logger replacement, and does so by default. | |
6353 | ||
6354 | * Optionally store all locally generated coredumps in the | |
6355 | journal along with meta data. | |
6356 | ||
6357 | * systemd-tmpfiles learnt four new commands: n, L, c, b, for | |
6358 | writing short strings to files (for usage for /sys), and for | |
6359 | creating symlinks, character and block device nodes. | |
6360 | ||
6361 | * New unit file option ControlGroupPersistent= to make cgroups | |
6362 | persistent, following the mechanisms outlined in | |
6363 | http://www.freedesktop.org/wiki/Software/systemd/PaxControlGroups | |
6364 | ||
6365 | * Support multiple local RTCs in a sane way | |
6366 | ||
6367 | * No longer monopolize IO when replaying readahead data on | |
6368 | rotating disks, since we might starve non-file-system IO to | |
6369 | death, since fanotify() will not see accesses done by blkid, | |
6370 | or fsck. | |
6371 | ||
d28315e4 | 6372 | * Do not show kernel threads in systemd-cgls anymore, unless |
220a21d3 LP |
6373 | requested with new -k switch. |

6378 | CHANGES WITH 38: | |
b6a86739 | 6379 | |
220a21d3 LP |
6380 | * This is mostly a test release, but incorporates many |
6381 | bugfixes. | |
6382 | ||
6383 | * The git repository moved to: | |
6384 | git://anongit.freedesktop.org/systemd/systemd | |
6385 | ssh://git.freedesktop.org/git/systemd/systemd | |
6386 | ||
6387 | * First release with the journal | |
6388 | http://0pointer.de/blog/projects/the-journal.html | |
6389 | ||
6390 | * The journal replaces both systemd-kmsg-syslogd and | |
6391 | systemd-stdout-bridge. | |
6392 | ||
6393 | * New sd_pid_get_unit() API call in libsystemd-logind | |
6394 | ||
6395 | * Many systemadm clean-ups | |
6396 | ||
6397 | * Introduce remote-fs-pre.target which is ordered before all | |
6398 | remote mounts and may be used to start services before all | |
6399 | remote mounts. | |
6400 | ||
6401 | * Added Mageia support | |
6402 | ||
6403 | * Add bash completion for systemd-loginctl | |
6404 | ||
6405 | * Actively monitor PID file creation for daemons which exit in | |
6406 | the parent process before having finished writing the PID | |
6407 | file in the daemon process. Daemons which do this need to be | |
6408 | fixed (i.e. PID file creation must have finished before the | |
6409 | parent exits), but we now react a bit more gracefully to them. | |
6410 | ||
6411 | * Add colourful boot output, mimicking the well-known output | |
6412 | of existing distributions. | |
6413 | ||
6414 | * New option PassCredentials= for socket units, for | |
6415 | compatibility with a recent kernel ABI breakage. | |
6416 | ||
6417 | * /etc/rc.local is now hooked in via a generator binary, and | |
6418 | thus will no longer act as synchronization point during | |
6419 | boot. | |
6420 | ||
6421 | * systemctl list-unit-files now supports --root=. | |
6422 | ||
6423 | * systemd-tmpfiles now understands two new commands: z, Z for | |
6424 | relabelling files according to the SELinux database. This is | |
6425 | useful to apply SELinux labels to specific files in /sys, | |
6426 | among other things. | |
6427 | ||
6428 | * Output of SysV services is now forwarded to both the console | |
6429 | and the journal by default, not only just the console. | |
6430 | ||
6431 | * New man pages for all APIs from libsystemd-login. | |
6432 | ||
6433 | * The build tree got reorganized and a the build system is a | |
6434 | lot more modular allowing embedded setups to specifically | |
6435 | select the components of systemd they are interested in. | |
6436 | ||
6437 | * Support for Linux systems lacking the kernel VT subsystem is | |
6438 | restored. | |
6439 | ||
6440 | * configure's --with-rootdir= got renamed to | |
6441 | --with-rootprefix= to follow the naming used by udev and | |
6442 | kmod | |
6443 | ||
d28315e4 | 6444 | * Unless specified otherwise we will now install to /usr instead |
220a21d3 LP |
6445 | of /usr/local by default. |
6446 | ||
6447 | * Processes with '@' in argv[0][0] are now excluded from the | |
6448 | final shut-down killing spree, following the logic explained | |
6449 | in: | |
6450 | http://www.freedesktop.org/wiki/Software/systemd/RootStorageDaemons | |
6451 | ||
6452 | * All processes remaining in a service cgroup when we enter | |
6453 | the START or START_PRE states are now killed with | |
6454 | SIGKILL. That means it is no longer possible to spawn | |
6455 | background processes from ExecStart= lines (which was never | |
6456 | supported anyway, and bad style). | |
6457 | ||
6458 | * New PropagateReloadTo=/PropagateReloadFrom= options to bind | |
6459 | reloading of units together. | |
