* tree-wide: drop license boilerplateZbigniew Jędrzejewski-Szmek2018-08-24
| | | | | | | | | | 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.
* sleep: Move the error level debugging for write_mode and write_stateMario Limonciello2018-08-24
| | | | | | This makes it more consistent with other code used in the file. Signed-off-by: Mario Limonciello <>
* sleep: Add support for setting a disk offset when hibernatingMario Limonciello2018-08-24
| | | | | | | | | | | The Linux kernel is adding support for configuring the offset into a disk. This allows swapfiles to be more usable as users will no longer need to set the offset on their kernel command line. Use this API in systemd when hibernating as well. Signed-off-by: Mario Limonciello <>
* Rename suspend-to-hibernate to suspend-then-hibernateMario Limonciello2018-08-24
| | | | | Per some discussion with Gnome folks, they would prefer this name as it's more descriptive of what's happening.

* fileio: return 0 from read_one_line_file on successZbigniew Jędrzejewski-Szmek2017-11-22
| | | | Fixup for f4b51a2d09. Suggested by Evgeny Vereshchagin.
* fileio: make write_string_stream() accept flags parameterLennart Poettering2017-09-22
| | | | | | Let's make write_string_stream() and write_string_file() more alike, and pass the same flag set so that we can remove a number of boolean parameters.
* Add abstraction model for BPF programsDaniel Mack2017-11-20
| | | | | This object takes a number of bpf_insn members and wraps them together with the in-kernel reference id. Will be needed by the firewall code.

* General: Update build system to upstream support of meson+ninja.Sven Eden2017-08-04
| | | | | | | | Upstream thinks, that the auto tools are too 'legacy', or that they are at least no longer fitting. We follow, as the classic auto tools files have been removed, so no other choice here...
* Prep v233: Add missing updates from upstream in src/sleepSven Eden2017-07-17
* basic/exec-util: add support for synchronous (ordered) executionZbigniew Jędrzejewski-Szmek2017-07-17
| | | | | | | | | | | | | | | | | | | | The output of processes can be gathered, and passed back to the callee. (This commit just implements the basic functionality and tests.) After the preparation in previous commits, the change in functionality is relatively simple. For coding convenience, alarm is prepared *before* any children are executed, and not before. This shouldn't matter usually, since just forking of the children should be pretty quick. One could also argue that this is more correct, because we will also catch the case when (for whatever reason), forking itself is slow. Three callback functions and three levels of serialization are used: - from individual generator processes to the generator forker - from the forker back to the main process - deserialization in the main process v2: - replace an structure with an indexed array of callbacks
* basic/util: move execute_directory() to separate fileZbigniew Jędrzejewski-Szmek2017-07-17
| | | | It's a fairly specialized function. Let's make new files for it and the tests.
* tree-wide: add SD_ID128_MAKE_STR, remove LOG_MESSAGE_IDZbigniew Jędrzejewski-Szmek2017-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Embedding sd_id128_t's in constant strings was rather cumbersome. We had SD_ID128_CONST_STR which returned a const char[], but it had two problems: - it wasn't possible to statically concatanate this array with a normal string - gcc wasn't really able to optimize this, and generated code to perform the "conversion" at runtime. Because of this, even our own code in coredumpctl wasn't using SD_ID128_CONST_STR. Add a new macro to generate a constant string: SD_ID128_MAKE_STR. It is not as elegant as SD_ID128_CONST_STR, because it requires a repetition of the numbers, but in practice it is more convenient to use, and allows gcc to generate smarter code: $ size .libs/elogind{,-logind,-journald}{.old,} text data bss dec hex filename 1265204 149564 4808 1419576 15a938 .libs/elogind.old 1260268 149564 4808 1414640 1595f0 .libs/elogind 246805 13852 209 260866 3fb02 .libs/elogind-logind.old 240973 13852 209 255034 3e43a .libs/elogind-logind 146839 4984 34 151857 25131 .libs/elogind-journald.old 146391 4984 34 151409 24f71 .libs/elogind-journald It is also much easier to check if a certain binary uses a certain MESSAGE_ID: $ strings .libs/elogind.old|grep MESSAGE_ID MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x MESSAGE_ID=%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x%02x $ strings .libs/elogind|grep MESSAGE_ID MESSAGE_ID=c7a787079b354eaaa9e77b371893cd27 MESSAGE_ID=b07a249cd024414a82dd00cd181378ff MESSAGE_ID=641257651c1b4ec9a8624d7a40a9e1e7 MESSAGE_ID=de5b426a63be47a7b6ac3eaac82e2f6f MESSAGE_ID=d34d037fff1847e6ae669a370e694725 MESSAGE_ID=7d4958e842da4a758f6c1cdc7b36dcc5 MESSAGE_ID=1dee0369c7fc4736b7099b38ecb46ee7 MESSAGE_ID=39f53479d3a045ac8e11786248231fbf MESSAGE_ID=be02cf6855d2428ba40df7e9d022f03d MESSAGE_ID=7b05ebc668384222baa8881179cfda54 MESSAGE_ID=9d1aaa27d60140bd96365438aad20286
* Prep v231.2: Remove modes and states assertion in do_sleep()Sven Eden2017-06-21
| | | | | | | | It is perfectly valid to have NULL modes. The default configuration for suspend to ram is such a case. Having NULL states doesn't make any sense other than no suspension is possible any more. But a user might have set any *State value to an empty string, so better assume (and assert) nothing here.
* Prep v231: Reorganize elogind specific code in login/logind-action.cSven Eden2017-06-16
| | | | | | | | | - Move elogind specific code in login/logind-action.c to login/elogind-action.c - Remove login/logind-sleep.* - Add src/sleep from upstream - Integrate the systemd-sleep utility, so future fixes and updates will be easier to spot and to apply.
* Remove src/sleepAndy Wingo2015-04-19
* remove unused includesThomas Hindoe Paaboel Andersen2015-02-23
| | | | | | This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
* Implement masking and overriding of generatorsZbigniew Jędrzejewski-Szmek2015-01-11
| | | | | | | | | | | | | | | | | | | | | | Sometimes it is necessary to stop a generator from running. Either because of a bug, or for testing, or some other reason. The only way to do that would be to rename or chmod the generator binary, which is inconvenient and does not survive upgrades. Allow masking and overriding generators similarly to units and other configuration files. For the systemd instance, masking would be more common, rather than overriding generators. For the user instances, it may also be useful for users to have generators in $XDG_CONFIG_HOME to augment or override system-wide generators. Directories are searched according to the usual scheme (/usr/lib, /usr/local/lib, /run, /etc), and files with the same name in higher priority directories override files with the same name in lower priority directories. Empty files and links to /dev/null mask a given name.
* Simplify execute_directory()Zbigniew Jędrzejewski-Szmek2015-01-11
| | | | | | | | | Remove the optional sepearate opening of the directory, it would be just too complicated with the change to multiple directories. Move the middle of execute_directory() to a seperate function to make it easier to grok.
* sleep: drop redundant MESSAGE= prefixLennart Poettering2014-12-09
* treewide: another round of simplificationsMichal Schmidt2014-11-28
| | | | | Using the same scripts as in f647962d64e "treewide: yet more log_*_errno + return simplifications".
* treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt2014-11-28
| | | | | | | | | | | If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
* treewide: more log_*_errno() conversions, multiline callsMichal Schmidt2014-11-28
| | | | | | | | | | | | Basically: find . -name '*.[ch]' | while read f; do perl -i.mmm -e \ 'local $/; local $_=<>; s/log_(debug|info|notice|warning|error|emergency)\("([^"]*)%s"([^;]*),\s*strerror\(-?([->a-zA-Z_]+)\)\);/log_\1_errno(\4, "\2%m"\3);/gms;print;' \ $f; done Plus manual indentation fixups.
* log: fix order of log_unit_struct() to match other logging callsLennart Poettering2014-11-28
| | | | | Also, while we are at it, introduce some syntactic sugar for creating ERRNO= and MESSAGE= structured logging fields.
* Unify parse_argv styleZbigniew Jędrzejewski-Szmek2014-08-03
| | | | | | | | | | | | | | | | getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.
* firstboot: get rid of firstboot generator again, introduce ↵Lennart Poettering2014-07-07
| | | | | | | | ConditionFirstBoot= instead As Zbigniew pointed out a new ConditionFirstBoot= appears like the nicer way to hook in systemd-firstboot.service on first boots (those with /etc unpopulated), so let's do this, and get rid of the generator again.
* firstboot: add new component to query basic system settings on first boot, ↵Lennart Poettering2014-07-07
| | | | | | | | | | | | | | | | | | | | or when creating OS images offline A new tool "systemd-firstboot" can be used either interactively on boot, where it will query basic locale, timezone, hostname, root password information and set it. Or it can be used non-interactively from the command line when prepareing disk images for booting. When used non-inertactively the tool can either copy settings from the host, or take settings on the command line. $ systemd-firstboot --root=/path/to/my/new/root --copy-locale --copy-root-password --hostname=waldi The tool will be automatically invoked (interactively) now on first boot if /etc is found unpopulated. This also creates the infrastructure for generators to be notified via an environment variable whether they are running on the first boot, or not.

* coredump: optionally store coredumps on disk, not in the journalLennart Poettering2014-06-19
| | | | | | | | Introduce a new configuration file /etc/systemd/coredump.conf to configure when to place coredumps in the journal and when on disk. Since the coredumps are quite large, default to storing them only on disk.

* clients: unify how we invoke getopt_long()Lennart Poettering2013-11-06
| | | | | Among other things this makes sure we always expose a --version command and show it in the help texts.
* systemd-sleep: add support for freeze and standbyZbigniew Jędrzejewski-Szmek2013-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | A new config file /etc/systemd/sleep.conf is added. It is parsed by systemd-sleep and logind. The strings written to /sys/power/disk and /sys/power/state can be configured. This allows people to use different modes of suspend on systems with broken or special hardware. Configuration is shared between systemd-sleep and logind to enable logind to answer the question "can the system be put to sleep" as correctly as possible without actually invoking the action. If the user configured systemd-sleep to only use 'freeze', but current kernel does not support it, logind will properly report that the system cannot be put to sleep.;a=commit;h=7e73c5ae6e7991a6c01f6d096ff8afaef4458c36 SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed since they were used in only a few places and with the addition of /etc/systemd/sleep.conf it becomes easier to just append the name of each file to the dir name.
* util: rename write_one_line_file() to write_string_file()Lennart Poettering2013-04-03
| | | | | You can write much more than just one line with this call (and we frequently do), so let's correct the naming.
* honor SELinux labels, when creating and writing config filesHarald Hoyer2013-02-14
| | | | | | | Also split out some fileio functions to fileio.c and provide a SELinux aware pendant in fileio-label.c see
* logind: support for hybrid sleep (i.e. suspend+hibernate at the same time)Lennart Poettering2012-10-28
* log: introduce a macro to format message idZbigniew Jędrzejewski-Szmek2012-10-13
| | | | | | | The MESSAGE_ID=... stanza will appear in countless number of places. It is just too long to write it out in full each time. Incidentally, this also fixes a typo of MESSSAGE is three places.
* journal: generate structured journal messages for a number of eventsLennart Poettering2012-09-03
* sleep: Don't call execute_directory() on a binaryMatthias Clasen2012-06-01
