* tree-wide: remove Lennart's copyright linesLennart Poettering2018-06-141-4/+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| | | | | | | | | | | These lines are generally out-of-date, incomplete and unnecessary.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.
* 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.
* condition: introduce condition_takes_path()Yu Watanabe2018-01-011-0/+14
| | | | The function will be used in later commits.
* core,udev,networkd: add ConditionKernelVersion=Lennart Poettering2017-12-261-0/+1
| | | | | | | | | | This adds a simple condition/assert/match to the service manager, to udev's .link handling and to networkd, for matching the kernel version string. In this version we only do fnmatch() based globbing, but we might want to extend that to version comparisons later on, if we like, by slightly extending the syntax with ">=", "<=", ">", "<" and "==" expressions.
* condition: Create AssertControlGroupController (#7630)Chris Down2017-12-181-0/+2
| | | | | | | | | | | | | | | | | | Up until now, the behaviour in systemd has (mostly) been to silently ignore failures to action unit directives that refer to an unavailble controller. The addition of AssertControlGroupController and its conditional counterpart allow explicit specification of the desired behaviour when such a situation occurs. As for how this can happen, it is possible that a particular controller is not available in the cgroup hierarchy. One possible reason for this is that, in the running kernel, the controller simply doesn't exist -- for example, the CPU controller in cgroup v2 has only recently been merged and was out of tree until then. Another possibility is that the controller exists, but has been forcibly disabled by `cgroup_disable=` on the kernel command line. In future this will also support whatever comes out of issue #7624, `DefaultXAccounting=never`, or similar.
* Add SPDX license identifiers to source files under the LGPLZbigniew Jędrzejewski-Szmek2017-11-191-0/+1
| | | | | This follows what the kernel is doing, c.f. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5fd54ace4721fc5ce2bb5aef6318fcf17f421460.
* core: add ConditionUser and ConditionGroupFelipe Sateler2017-05-261-0/+3
| | | | | | | This adds two options that are useful for user units. In particular, it is useful to check ConditionUser=!0 to not start for the root user. Closes: #5187
* tree-wide: remove Emacs lines from all filesDaniel Mack2016-02-101-2/+0
| | | | | This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
* tree-wide: make condition_free_list return NULLZbigniew Jędrzejewski-Szmek2014-12-191-1/+1

* shared: rename condition-util.[ch] to condition.[ch]Lennart Poettering2014-11-061-0/+96
Now that we only have one file with condition implementations around, we can drop the -util suffix and simplify things a bit.
