* reboot-util: Add some basic validation on reboot argumentsDaan De Meyer2024-05-021-0/+10
| | | | Let's only accept valid ASCII and put a size limit on reboot arguments.
* reboot-util: cache the result of shall_restore_stateMike Yuan2023-08-131-5/+9
|
* proc-cmdline: make proc_cmdline_get_bool() take flagsYu Watanabe2023-08-091-1/+1
| | | | | | All other command line parsers takes flags. Let's make proc_cmdline_get_bool() also take flags. Though, currently, no flag is set by the caller.
* tree-wide: use -EBADF for fd initializationZbigniew Jędrzejewski-Szmek2022-12-191-1/+1
| | | | | | | | | | | | | | | | -1 was used everywhere, but -EBADF or -EBADFD started being used in various places. Let's make things consistent in the new style. Note that there are two candidates: EBADF 9 Bad file descriptor EBADFD 77 File descriptor in bad state Since we're initializating the fd, we're just assigning a value that means "no fd yet", so it's just a bad file descriptor, and the first errno fits better. If instead we had a valid file descriptor that became invalid because of some operation or state change, the other errno would fit better. In some places, initialization is dropped if unnecessary.
* treewide: drop "RUN_" from "RUN_WITH_UMASK"Zbigniew Jędrzejewski-Szmek2022-12-131-1/+1
| | | | | | RUN_WITH_UMASK was initially conceived for spawning externals progs with the umask set. But nowadays we use it various syscalls and stuff that doesn't "run" anything, so the "RUN_" prefix has outlived its usefulness.
* reboot-util: drop unnecessary castYu Watanabe2022-11-041-3/+3
| | | | Follow-up for ede5a78f50ed2d5f86dc7a117de2a51b397d52d4.
* reboot-util: drop redundant headersYu Watanabe2022-11-041-5/+0
| | | | Follow-up for ede5a78f50ed2d5f86dc7a117de2a51b397d52d4.
* shutdown: Add Xen kexec supportSamuel Thibault2022-11-021-0/+88
| | | | | | In the Xen case, it's the hypervisor which manages kexec. We thus have to ask it whether a kernel is loaded, instead of relying on /sys/kernel/kexec_loaded.
* license: LGPL-2.1+ -> LGPL-2.1-or-laterYu Watanabe2020-11-091-1/+1

* shared/reboot-util: indentation updateZbigniew Jędrzejewski-Szmek2020-04-161-7/+6

* util-lib: move shall_restore_state() to shared/reboot-utilZbigniew Jędrzejewski-Szmek2019-09-161-0/+12
| | | | | It's just a small function, but it is higher-level functionality. I don't see a good place for it, reboot-util.[ch] seems least bad
* logind: Add support for RebootParameterVesa Jääskeläinen2019-03-221-0/+12
| | | | | | | | | This adds support for user to set & get reboot parameter for reboot. As callee would be next issuing Reboot call same policy checks are being used. If unit file issuing the reboot action defines RebootArgument (or similar) that setting takes precedence.
* systemctl: restore "systemctl reboot ARG" functionalityVesa Jääskeläinen2019-03-221-1/+4
| | | | | | | | | | | | | | | | | | | | | | Commit d85515edcf9700dc068201ab9f7103f04f3b25b2 changed logic how reboot is executed. That commit changed behavior to use emergency action reboot code path to perform the reboot. This inadvertently broke rebooting with argument: $ systemctl reboot custom-reason Restore original behavior so that if reboot service unit similar to systemd-reboot.service is executed it is possible to override reboot reason with "systemctl reboot ARG". When "systemctl reboot ARG" is executed ARG is placed in file /run/systemd/reboot-param and reboot is issued using logind's Reboot dbus-service. If RebootArgument is specified in systemd-reboot.service it takes precedence over what systemctl sets. Fixes: #11828
* Move various files that don't need to be in basic/ to shared/Zbigniew Jędrzejewski-Szmek2018-11-201-0/+83
This doesn't have much effect on the final build, because we link libbasic.a into libsystemd-shared.so, so in the end, all the object built from basic/ end up in libsystemd-shared. And when the static library is linked into binaries, any objects that are included in it but are not used are trimmed. Hence, the size of output artifacts doesn't change: $ du -sb /var/tmp/inst* 54181861 /var/tmp/inst1 (old) 54207441 /var/tmp/inst1s (old split-usr) 54182477 /var/tmp/inst2 (new) 54208041 /var/tmp/inst2s (new split-usr) (The negligible change in size is because libsystemd-shared.so is bigger by a few hundred bytes. I guess it's because symbols are named differently or something like that.) The effect is on the build process, in particular partial builds. This change effectively moves the requirements on some build steps toward the leaves of the dependency tree. Two effects: - when building items that do not depend on libsystemd-shared, we build less stuff for libbasic.a (which wouldn't be used anyway, so it's a net win). - when building items that do depend on libshared, we reduce libbasic.a as a synchronization point, possibly allowing better parallelism. Method: 1. copy list of .h files from src/basic/meson.build to /tmp/basic 2. $ for i in $(grep '.h$' /tmp/basic); do echo $i; git --no-pager grep "include \"$i\"" src/basic/ 'src/lib*' 'src/nss-*' 'src/journal/sd-journal.c' |grep -v "${i%.h}.c";echo ;done | less
