* manager: fix/change evaluation of ConditionFirstBootZbigniew Jędrzejewski-Szmek2022-10-011-9/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code to evaluate the kernel command line option was busted because it was doing 'return b == !!r' at a point where 'r > 0'. Thus we'd return "true" in both cases: $ SYSTEMD_PROC_CMDLINE=systemd.condition-first-boot build/systemd-analyze condition 'ConditionFirstBoot=true' test.service: ConditionFirstBoot=true succeeded. Conditions succeeded. $ SYSTEMD_PROC_CMDLINE=systemd.condition-first-boot build/systemd-analyze condition 'ConditionFirstBoot=false' test.service: ConditionFirstBoot=false succeeded. Conditions succeeded. We only use 'ConditionFirstBoot=true' in units, so this wasn't noticed. But I think the logic is broken in general: the condition should evaluate as true only during initial boot. If we rerun the units at later points, we should not consider ConditionFirstBoot to be true. Also, the first boot logic is also used in pid1 itself. AFAICT, for two things: in first boot machine-id is initialized transiently (this allows first-boot operations to be restarted if boot fails), and preset-all is executed. But this logic was different and separate from the logic to evaluate ConditionFirstBoot. The distinction is abolished, and the operations in pid1 now use the same logic as ConditionFirstBoot, which means that the kernel command line option is checked, and condition_test_first_boot() just tests whether pid1 thinks we're in first boot. This makes things easier to grok for the user: there's just one condition for "first boot" and it applies to both pid1 and units.

* sd-id128: document everywhere that we treat all UUIDs as Variant 1Lennart Poettering2021-06-151-9/+7
| | | | | | | | So in theory UUID Variant 2 (i.e. microsoft GUIDs) are supposed to be displayed in native endian. That is of course a bad idea, and Linux userspace generally didn't implement that, i.e. uuidd and similar. Hence, let's not bother either, but let's document that we treat everything the same as Variant 1, even if it declares something else.

* 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: 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.

* 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.

* sd-id128: add new sd_id128_get_machine_app_specific() APILennart Poettering2016-11-291-7/+8
| | | | | | | | | | | | This adds an API for retrieving an app-specific machine ID to sd-id128. Internally it calculates HMAC-SHA256 with an 128bit app-specific ID as payload and the machine ID as key. (An alternative would have been to use siphash for this, which is also cryptographically strong. However, as it only generates 64bit hashes it's not an obvious choice for generating 128bit IDs.) Fixes: #4667

* core: Add machine-id settingNils Carlson2016-01-121-0/+6
| | | | | | | | | | Allow for overriding all other machine-ids which may be present on the system using a kernel command line systemd.machine_id or --machine-id= option. This is especially useful for network booted systems where the machine-id needs to be static, or for containers where a specific machine-id is wanted.
* man: use "=" when referring to configuration file settingsZbigniew Jędrzejewski-Szmek2015-09-301-1/+1
| | | | | | | This convention is almost universal in systemd man pages, and makes it easier to visually parse the docs. Also fix some markup along the way.
* machine-id-commit: merge machine-id-commit functionality into machine-id-setupLennart Poettering2015-09-291-1/+1
| | | | | | | | | | | | | And remove machine-id-commit as separate binary. There's really no point in keeping this separate, as the sources are pretty much identical, and have pretty identical interfaces. Let's unify this in one binary. Given that machine-id-commit was a private binary of systemd (shipped in /usr/lib/) removing the tool is not an API break. While we are at it, improve the documentation of the command substantially.
* man: revert dynamic paths for split-usr setupsTom Gundersen2015-06-181-4/+1
| | | | | | | | | | | | | | | | | | | | | | | 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 Brandenburger2015-05-281-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* relicense to LGPLv2.1 (with exceptions)Lennart Poettering2012-04-121-4/+4
| | | | | | | | | | | | | | We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

* main: introduce /etc/machine-idLennart Poettering2011-03-041-0/+104
This is supposed to play the same roles /var/lib/dbus/machine-id, however fixes a couple of problems: - It is available during early boot since it is stored in /etc - Removes the ID from the D-Bus context and moves it into a system context, thus hopefully lowering hesitation by people to use it. - It is generated at installation time. If the file is empty at boot time it will be mounted over with a randomly generated ID, which is not saved to disk. This is useful to support state-less machines with no transient or writable /etc configuration.
