* tree-wide: drop quotes from around [section]Zbigniew Jędrzejewski-Szmek2020-07-061-1/+1
| | | | | | | For users, the square brackets already serve as markup and clearly delineate the section name from surrounding text. Putting additional markup around that only adds clutter. Also, we were very inconsistent in using the quotes. Let's just drop them altogether.
* tree-wide: fixes for assorted grammar and spelling issuesZbigniew Jędrzejewski-Szmek2020-07-061-1/+1

* man: use same header for all filesZbigniew Jędrzejewski-Szmek2019-03-141-1/+1
| | | | | | | The "include" files had type "book" for some raeason. I don't think this is meaningful. Let's just use the same everywhere. $ perl -i -0pe 's^..DOCTYPE (book|refentry) PUBLIC "-//OASIS//DTD DocBook XML V4.[25]//EN"\s+"http^<!DOCTYPE refentry PUBLIC "-//OASIS//DTD DocBook XML V4.5//EN"\n "http^gms' man/*.xml
* man: standarize on one-line license headerZbigniew Jędrzejewski-Szmek2019-03-141-4/+1
| | | | | | No need to waste space, and uniformity is good. $ perl -i -0pe 's|\n+<!--\s*SPDX-License-Identifier: LGPL-2.1..\s*-->|\n<!-- SPDX-License-Identifier: LGPL-2.1+ -->|gms' man/*.xml
* man: move all config file options to one sectionZbigniew Jędrzejewski-Szmek2019-02-131-1/+1
| | | | | | We had "SYSTEM MANAGER DIRECTIVES" which was a misnomer already, because it also listed user manager stuff. Let's make this a more general section and move the items for other services there too (from "MISCELANENOUS").

* man: drop mode line in file headersZbigniew Jędrzejewski-Szmek2018-07-031-1/+1
| | | | | This is already included in .dir-locals, so we don't need it in the files themselves.
* man: drop unused <authorgroup> tags from man sourcesZbigniew Jędrzejewski-Szmek2018-06-141-9/+0
| | | | | | | | | | | | Docbook styles required those to be present, even though the templates that we use did not show those names anywhere. But something changed semi-recently (I would suspect docbook templates, but there was only a minor version bump in recent years, and the changelog does not suggest anything related), and builds now work without those entries. Let's drop this dead weight. Tested with F26-F29, debian unstable. $ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml
* tree-wide: remove Lennart's copyright linesLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | These lines are generally out-of-date, incomplete and unnecessary. With SPDX and git repository much more accurate and fine grained information about licensing and authorship is available, hence let's drop the per-file copyright notice. Of course, removing copyright lines of others is problematic, hence this commit only removes my own lines and leaves all others untouched. It might be nicer if sooner or later those could go away too, making git the only and accurate source of authorship information.
* tree-wide: drop 'This file is part of systemd' blurbLennart Poettering2018-06-141-2/+0
| | | | | | | | | | | | | | | | This part of the copyright blurb stems from the GPL use recommendations: https://www.gnu.org/licenses/gpl-howto.en.html The concept appears to originate in times where version control was per file, instead of per tree, and was a way to glue the files together. Ultimately, we nowadays don't live in that world anymore, and this information is entirely useless anyway, as people are very welcome to copy these files into any projects they like, and they shouldn't have to change bits that are part of our copyright header for that. hence, let's just get rid of this old cruft, and shorten our codebase a bit.
* Use a dash-truncated drop-in for user-%j.slice configurationZbigniew Jędrzejewski-Szmek2018-04-251-11/+0
| | | | | | | | | | | | | | | | | | | This removes the UserTasksMax= setting in logind.conf. Instead, the generic TasksMax= setting on the slice should be used. Instead of a transient unit we use a drop-in to tweak the default definition of a .slice. It's better to use the normal unit mechanisms instead of creating units on the fly. This will also make it easier to start user@.service independently of logind, or set additional settings like MemoryMax= for user slices. The setting in logind is removed, because otherwise we would have two sources of "truth": the slice on disk and the logind config. Instead of trying to coordinate those two sources of configuration (and maintainer overrides to both), let's just convert to the new one fully. Right now now automatic transition mechanism is provided. logind will emit a hint when it encounters the setting, but otherwise it will be ignored. Fixes #2556.
* man: add a new page with a general description of common syntaxZbigniew Jędrzejewski-Szmek2018-04-181-4/+4
| | | | | | | | We have a common parser, but for the user it might be completely unobvious that the same general rules apply to all those files. Let's add a page about the basic syntax so that the more specific pages don't have to repeat those details.
* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-04-061-13/+0
| | | | | | | | | | Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.
* Rename suspend-to-hibernate to suspend-then-hibernateMario Limonciello2018-03-281-2/+2
| | | | | Per some discussion with Gnome folks, they would prefer this name as it's more descriptive of what's happening.

* Introduce suspend-to-hibernate (#8274)Mario Limonciello2018-03-081-2/+4
| | | | | | | | | | | | | | Suspend to Hibernate is a new sleep method that invokes suspend for a predefined period of time before automatically waking up and hibernating the system. It's similar to HybridSleep however there isn't a performance impact on every suspend cycle. It's intended to use with systems that may have a higher power drain in their supported suspend states to prevent battery and data loss over an extended suspend cycle.

* Suspend on lid close based on power status. (#8016)Simon Fowler2018-02-091-2/+8
| | | | | | | This change adds support for controlling the suspend-on-lid-close behaviour based on the power status as well as whether the machine is docked or has an external monitor. For backwards compatibility the new configuration file variable is ignored completely by default, and must be set explicitly before being considered in any decisions.

* | logind: update empty and "infinity" handling for [User]TasksMax (#3835)Tejun Heo2016-08-181-2/+3
|/ | | | | | | | | | | | | | | | The parsing functions for [User]TasksMax were inconsistent. Empty string and "infinity" were interpreted as no limit for TasksMax but not accepted for UserTasksMax. Update them so that they're consistent with other knobs. * Empty string indicates the default value. * "infinity" indicates no limit. While at it, replace opencoded (uint64_t) -1 with CGROUP_LIMIT_MAX in TasksMax handling. v2: Update empty string to indicate the default value as suggested by Zbigniew Jędrzejewski-Szmek. v3: Fixed empty UserTasksMax handling.
* logind: change TasksMax= value for user logins to 33%Lennart Poettering2016-07-221-5/+4
| | | | | | | | | | | | | | | | | | | | Let's change from a fixed value of 12288 tasks per user to a relative value of 33%, which with the kernel's default of 32768 translates to 10813. This is a slight decrease of the limit, for no other reason than "33%" sounding like a nice round number that is close enough to 12288 (which would translate to 37.5%). (Well, it also has the nice effect of still leaving a bit of room in the PID space if there are 3 cooperating evil users that try to consume all PIDs... Also, I like my bikesheds blue). Since the new value is taken relative, and machined's TasksMax= setting defaults to 16384, 33% inside of containers is usually equivalent to 5406, which should still be ample space. To summarize: | on the host | in the container old default | 12288 | 12288 new default | 10813 | 5406
* logind: enforce a limit on inhibitors we hand outLennart Poettering2016-05-051-0/+7
| | | | | | | | For similar reasons as the recent addition of a limit on sessions. Note that we don't enforce a limit on inhibitors per-user currently, but there's an implicit one, since each inhibitor takes up one fd, and fds are limited via RLIMIT_NOFILE, and the limit on the number of processes per user.
* logind: enforce a limit on current user sessionsLennart Poettering2016-05-051-0/+9
| | | | | | | | | | | We really should put limits on all resources we manage, hence add one to the number of concurrent sessions, too. This was previously unbounded, hence set a relatively high limit of 8K by default. Note that most PAM setups will actually invoke pam_systemd prefixed with "-", so that the return code of pam_systemd is ignored, and the login attempt succeeds anyway. On systems like this the session will be created but is not tracked by systemd.

* logind: make KillOnlyUsers override KillUserProcessesZbigniew Jędrzejewski-Szmek2016-04-211-12/+13
| | | | | | | Instead of KillOnlyUsers being a filter for KillUserProcesses, it can now be used to specify users to kill, independently of the KillUserProcesses setting. Having the settings orthogonal seems to make more sense. It also makes KillOnlyUsers symmetrical to KillExcludeUsers.
* logind: flip KillUserProcesses to on by defaultZbigniew Jędrzejewski-Szmek2016-04-211-1/+1
| | | | | | | | | | | | | | | | | | This ensures that users sessions are properly cleaned up after. The admin can still enable or disable linger for specific users to allow them to run processes after they log out. Doing that through the user session is much cleaner and provides better control. dbus daemon can now be run in the user session (with --enable-user-session, added in 1.10.2), and most distributions opted to pick this configuration. In the normal case it makes a lot of sense to kill remaining processes. The exception is stuff like screen and tmux. But it's easy enough to work around, a simple example was added to the man page in previous commit. In the long run those services should integrate with the systemd users session on their own. https://bugs.freedesktop.org/show_bug.cgi?id=94508 https://github.com/systemd/systemd/issues/2900
* man: expand description of lingering and KillUserProcesses settingZbigniew Jędrzejewski-Szmek2016-04-211-17/+32
| | | | | | | | | | The description in the man page was wrong, KillUserProcesses does not kill all processes of the user. Describe what the setting does, and also add links between the relavant sections of the manual. Also, add an extensive example which shows how to launch screen in the background.

* logind: add a new UserTasksMax= setting to logind.confLennart Poettering2015-11-131-2/+13
| | | | | | | | | | This new setting configures the TasksMax= field for the slice objects we create for each user. This alters logind to create the slice unit as transient unit explicitly instead of relying on implicit generation of slice units by simply starting them. This also enables us to set a friendly description for slice units that way.

* man: revert dynamic paths for split-usr setupsTom Gundersen2015-06-181-7/+4
| | | | | | | | | | | | | | | | | | | | | | | This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.
* man: generate configured paths in manpagesFilipe Brandenburger2015-05-281-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

* login: make hold-off timeout configurableDavid Herrmann2015-03-061-0/+15
| | | | | | | | | | | | | | | | | This introduces 'HoldoffTimeoutSec' to logind.conf to make IGNORE_LID_SWITCH_{SUSPEND,STARTUP}_USEC configurable. Background: If an external monitor is connected, or if the system is docked, we want to ignore LID events. This is required to support setups where a laptop is used with external peripherals while the LID is closed. However, this requires us to probe all hot-plugged devices before reacting to LID events. But with modern buses like USB, the standards do not impose any timeout on the slots, so we have no chance to know whether a given slot is used or not. Hence, after resume and startup, we have to wait a fixed timeout to give the kernel a chance to probe devices. Our timeout has always been generous enough to support even the slowest devices. However, a lot of people didn't use these features and wanted to disable the hold-off timer. Now we provide a knob to do that.
