2014-11-28treewide: another round of simplificationsMichal Schmidt
Using the same scripts as in f647962d64e "treewide: yet more log_*_errno + return simplifications".
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
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.
2014-11-28treewide: more log_*_errno + return simplificationsMichal Schmidt
2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-11-26swap: restore support for nofailZbigniew Jędrzejewski-Szmek
systemd stops adding automatic dependencies on swap.target to swap units. If a dependency is required, it has to be added by unit configuration. fstab-generator did that already, except that now it is modified to create a Requires or Wants type dependency, depending on whether nofail is specified in /etc/fstab. This makes .swap units obey the nofail/noauto options more or less the same as .mount units. Documentation is extended to clarify that, and to make systemd.mount(5) and system.swap(5) more similar. The gist is not changed, because current behaviour actually matches existing documentation. https://bugs.freedesktop.org/show_bug.cgi?id=86488
2014-11-07util: simplify proc_cmdline() to reuse get_process_cmdline()Lennart Poettering
Also, make all parsing of the kernel cmdline non-fatal.

2014-10-28swap: replace Discard= setting by a more generic Options= settingLennart Poettering
For now, it's systemd itself that parses the options string, but as soon as util-linux' swapon can take the option string directly with -o we should pass it on unmodified.
2014-10-10fstab-generator: Honor mount.usr*= on kernel command lineTobias Hunger
This allows to configure boot loader entries for systems where the root and usr filesystems are in different subvolumes (or even on different drives).
2014-10-03fstab-generator: Small cleanupTobias Hunger
2014-09-29fstab-generator: properly deal with discard as non-last optionZbigniew Jędrzejewski-Szmek
Previous code would only return correct results when discard was the last option. While at it, avoid incorrect behaviour for (invalid) 'pri' option not followed by '=...', and also do not return -1 as the error code.
2014-09-29swap: introduce Discard propertyJan Synacek
Process possible "discard" values from /etc/fstab.
2014-08-13util: allow strappenda to take any number of argsDave Reisner
This makes strappenda3 redundant, so we remove its usage and definition. Add a few tests along the way for sanity.
2014-07-07fstab-generator: fix trivial leakZbigniew Jędrzejewski-Szmek
2014-06-30fstab-generator: allow x-systemd.device-timeout for swap unitsZbigniew Jędrzejewski-Szmek
2014-06-30Move x-systemd-device.timeout handling from core to fstab-generatorZbigniew Jędrzejewski-Szmek
Instead of adjusting job timeouts in the core, let fstab-generator write out a dropin snippet with the appropriate JobTimeout. x-systemd-device.timeout option is removed from Options= line in the generated unit. The functions to write dropins are moved from core/unit.c to shared/dropin.c, to make them available outside of core. generator.c is moved to libsystemd-label, because it now uses functions defined in dropin.c, which are in libsystemd-label.
2014-06-23fstab-generator: simplify add_root_mountZbigniew Jędrzejewski-Szmek
2014-06-19stop complaining about unknown kernel cmdline optionsLennart Poettering
Also stop warning about unknown kernel cmdline options in the various tools, not just in PID 1
2014-03-11fstab-generator: when running in a container, ignore fstab entries referring ↵Lennart Poettering
to device nodes Since these device nodes will never appear in the container anyway there's no point in waiting for them. This makes it easier to boot images generated with general purpose installers like Anaconda which unconditionally populate /etc/fstab to boot in containers.
2014-03-07fstab-generator: the root partition is not optionalLennart Poettering
2014-03-07fstab-generator: merge /proc/cmdline parsing loops into oneLennart Poettering
2014-03-06generators: add Documentation= fields that point to the generator man pagesLennart Poettering
2014-03-06util: move more intellegince into parse_proc_cmdline()Lennart Poettering
Already split variable assignments before invoking the callback. And drop "rd." settings if we are not in an initrd.
2014-03-06generators: rework mount generatorsLennart Poettering
- Add support for finding and mounting /srv based on GPT data, similar to how we already handly /home. - Share the fsck logic between GPT, EFI and fstab generators - Make sure we never run the EFI generator inside containers - Drop DefaultDependencies=no from EFI mount units - Other fixes
2014-02-17Extract looping over /proc/cmdline into a shared functionZbigniew Jędrzejewski-Szmek
In cryptsetup-generator automatic cleanup had to be replaced with manual cleanup, and the code gets a bit longer. But existing code had the issue that it returned negative values from main(), which was wrong, so should be reworked anyway.
2014-02-10fstab-generator: Create fsck-root symlink with correct pathColin Guthrie
This was noticed in Brussels at the hackfest. The fstab-generator currently creates a broken symlink pointing to itself in /run/systemd/generator/local-fs.target.wants/ for systemd-fsck-root.service
2013-12-21fstab-generator: Do not try to fsck non-devicesThomas Bächler
This fixes a regression introduced in 64e70e4 where the mount fails when fstab is misconfigured with fs_passno > 0 on a virtual file system like nfs, and the type is specified as "auto".
2013-11-15fstab-generator: use RequiresOverridable for fsck unitsZbigniew Jędrzejewski-Szmek
This allows the user to disable fsck's by masking. If fsck fails, emergency target is started, the user might mount the unit using mount and disable fsck by masking the unit. In this case, .mount will be active because the mount is detect through /proc/self/mountinfo, but systemd-fsck@.service will still be in failed mode. This results in a funny situation where $ systemctl show -p ActiveState local-fs.target yyy.mount ActiveState=active ActiveState=active $ sudo systemctl start local-fs.target [sudo] password for test: Failed to start local-fs.target: Unit systemd-fsck@xxx.service is masked.
2013-11-15fsck,fstab-generator: be lenient about missing fsck.<type>Zbigniew Jędrzejewski-Szmek
If fstab contains 1 for passno, treat this as an error, but only warn briefly. If fstab doesn't contain this information, don't complain at all. Patch is complicated a bit by the fact that we might have the fstype specified in fstab or on /proc/cmdline, in which case we can check if we have the appropriate fsck tool, or not specified, or specified as auto, in which case we have to look and check the type of the filesystem ourselves. It cannot be done before the device appears, so it is too early in the generator phase, and it must be done directly in fsck service.
2013-11-06util: unify reading of /proc/cmdlineLennart Poettering
Instead of individually checking for containers in each user do this once in a new call proc_cmdline() that read the file only if we are not in a container.
2013-10-19fsck-root: only run when requested in fstabTom Gundersen
fsck-root is redundant in case an initrd is used, or in case the rootfs is never remounted 'rw', so the new default is the correct behavior for most users. For the rest, they should enable it in fstab.
2013-10-19fstab-generator: Generate explicit dependencies on systemd-fsck@.service ↵Thomas Bächler
instead of using FsckPassNo [tomegun: * order all fsck instances after fsck-root * check for OOM * added notes in the manpages]
2013-10-19fstab-generator: When parsing the root= cmdline option, set FsckPassNo to 1Thomas Bächler
[tomegun: without this we would never fsck the rootfs if it was directly mounted 'rw' from the initrd. We now risk fsck'ing it twice in the case it is mounted 'ro', so that should be addressed in a separate patch.]

clang FTW!
2013-09-16swap: create .wants symlink to 'auto' swap devicesTom Gundersen
As we load unit files lazily, we need to make sure something pulls in swap units that should be started automatically, otherwise the default dependencies will never be applied. This partially reinstates code removed in commit 64347fc2b983f33e7efb0fd2bb44e133fb9f30f4. Also don't order swap devices after swap.target when they are 'nofail'.
2013-09-11swap: handle nofail/noauto in coreTom Gundersen
2013-09-11mount: move device links handling from generatorTom Gundersen
This makes mount units work like swap units: when the backing device appears the mount unit will be started. v2: the device should want the mount unconditionally, not only for DefaultDependencies=yes
2013-09-11fstab-generator: use DefaultDependencies=yesTom Gundersen
This removes some redundancy between the generator and the core mount handling.
2013-08-14fstab-generator: log_oom() if automount_name is nullWANG Chao
2013-08-09fstab-generator: read rd.fstab=on/off switch correctlyWANG Chao
2013-08-09fstab-generator: respect noauto/nofail when adding sysroot mountWANG Chao
Currently we don't respect noauto/nofail root mount options (from rootflags kernel cmdline). We should map these two flags to the corresponding boolean variable noauto and nofail when calling add_mount().

2013-03-29Always use errno > 0 to help gccZbigniew Jędrzejewski-Szmek
gcc thinks that errno might be negative, and functions could return something positive on error (-errno). Should not matter in practice, but makes an -O4 build much quieter.
2013-03-29unit: replace remote-fs-setup.target by network-online.targetLennart Poettering
https://bugzilla.redhat.com/show_bug.cgi?id=787314
2013-03-26fstab-generator: drop x-initrd.rootfs mount optionHarald Hoyer
x-initrd.mount now has different meanings, if fstab-generator is called in the initramfs. initrd:/etc/fstab and x-initrd.mount defines mounts for the initrd-root-fs.target initrd:/sysroot/etc/fstab and x-initrd.mount defines mounts for the initrd-fs.target
2013-03-26fstab-generator: degrade the message about missing "root=" to log_debugHarald Hoyer
Some installation media (fedora at least) does not have and need a "root=" argument on the kernel command line.
2013-03-25units: introduce remote-fs-setup.target to pull in dependencies from remote ↵Lennart Poettering
mounts This introduces remote-fs-setup.target independently of remote-fs-pre.target. The former is only for pulling things in, the latter only for ordering. The new semantics: remote-fs-setup.target: is pulled in automatically by all remote mounts. Shall be used to pull in other units that want to run when at least one remote mount is set up. Is not ordered against the actual mount units, in order to allow activation of its dependencies even 'a posteriori', i.e. when a mount is established outside of systemd and is only picked up by it. remote-fs-pre.target: needs to be pulled in automatically by the implementing service, is otherwise not part of the initial transaction. This is ordered before all remote mount units. A service that wants to be pulled in and run before all remote mounts should hence have: a) WantedBy=remote-fs-setup.target -- so that it is pulled in b) Wants=remote-fs-pre.target + Before=remote-fs-pre.target -- so that it is ordered before the mount point, normally.
