2014-11-27log: rearrange log function namingLennart Poettering
- Rename log_meta() → log_internal(), to follow naming scheme of most other log functions that are usually invoked through macros, but never directly. - Rename log_info_object() to log_object_info(), simply because the object should be before any other parameters, to follow OO-style programming style.
2014-11-26manager: print fatal errors on the console tooZbigniew Jędrzejewski-Szmek
When booting in quiet mode, fatal messages would not be shown at all to the user. https://bugzilla.redhat.com/show_bug.cgi?id=1155468
2014-11-26manager: log some fatal errors at emergency levelZbigniew Jędrzejewski-Szmek
This adds a new log_emergency() function, which is equivalent to log_error() for non-PID-1, and logs at the highest priority for PID 1. Some messages which occur before freezing are converted to use it.
2014-11-23manager: let manager_free() handle NULLsZbigniew Jędrzejewski-Szmek
This makes the calling code a bit simpler.
2014-11-14kmod: move #ifdef checks for kmod-setup out of main.c into kmod-setup.cLennart Poettering
2014-11-14mount-setup: remove mount_setup_late()Daniel Mack
Turns out we can just do kmod_setup() earlier, before we do mount_setup(), so there's no need for mount_setup_late() anymore. Instead, put kdbusfs in mount_table[].
2014-11-13sd-bus: sync with kdbus upstream (ABI break)Daniel Mack
kdbus has seen a larger update than expected lately, most notably with kdbusfs, a file system to expose the kdbus control files: * Each time a file system of this type is mounted, a new kdbus domain is created. * The layout inside each mount point is the same as before, except that domains are not hierarchically nested anymore. * Domains are therefore also unnamed now. * Unmounting a kdbusfs will automatically also detroy the associated domain. * Hence, the action of creating a kdbus domain is now as privileged as mounting a filesystem. * This way, we can get around creating dev nodes for everything, which is last but not least something that is not limited by 20-bit minor numbers. The kdbus specific bits in nspawn have all been dropped now, as nspawn can rely on the container OS to set up its own kdbus domain, simply by mounting a new instance. A new set of mounts has been added to mount things *after* the kernel modules have been loaded. For now, only kdbus is in this set, which is invoked with mount_setup_late().
2014-11-07util: simplify proc_cmdline() to reuse get_process_cmdline()Lennart Poettering
Also, make all parsing of the kernel cmdline non-fatal.
2014-10-28mac: add mac_ prefix to distinguish origin security apisWaLyong Cho
2014-10-28core: remove system start timeout logic againLennart Poettering
The system start timeout as previously implemented would get confused by long-running services that are included in the initial system startup transaction for example by being cron-job-like long-running services triggered immediately at boot. Such long-running jobs would be subject to the default 15min timeout, esily triggering it. Hence, remove this again. In a subsequent commit, introduce per-target job timeouts instead, that allow us to control these timeouts more finegrained.

2014-10-17systemd: continue switch-root even if umount failsZbigniew Jędrzejewski-Szmek
Leaving the old root around seems better than aborting the switch.
2014-10-08core: map the 'rescue' argument to rescue.targetMantas Mikulėnas
Even though the 'emergency' and 'single' aliases come from sysvinit, the lack of 'rescue' is still quite confusing (caught me by surprise for the 9th time yet) and inconsistent with `systemctl rescue` as well.
2014-10-01core: limit timestamp to sane precisionZbigniew Jędrzejewski-Szmek
Anything below .1 s is meaningless anyway.

2014-08-26util: make use of newly added reset_signal_mask() call wherever appropriateLennart Poettering
2014-08-22core: introduce "poweroff" as new failure action typesLennart Poettering
Also, change the default action on a system start-up timeout to powering off.
2014-08-22core: add support for a configurable system-wide start-up timeoutLennart Poettering
When this system-wide start-up timeout is hit we execute one of the failure actions already implemented for services that fail. This should not only be useful on embedded devices, but also on laptops which have the power-button reachable when the lid is closed. This devices, when in a backpack might get powered on by accident due to the easily reachable power button. We want to make sure that the system turns itself off if it starts up due this after a while. When the system manages to fully start-up logind will suspend the machine by default if the lid is closed. However, in some cases we don't even get as far as logind, and the boot hangs much earlier, for example because we ask for a LUKS password that nobody ever enters. Yeah, this is a real-life problem on my Yoga 13, which has one of those easily accessible power buttons, even if the device is closed.
2014-08-15main,log: parse the log related kernel command line parameters at one place ↵Lennart Poettering
only, and for all tools Previously, we ended up parsing some of them three times: in main.c when processing the kernel cmdline, in main.c when processing the process cmdline (only for containers), and in log.c again. Let's streamline this, and only parse them in log.c In PID 1 also make sure we parse "quiet" first, and then override this with the more specific checks in log.c
2014-08-15main: minor code modernization for initializing the consoleLennart Poettering
2014-08-11log: never ever log to syslog from PID 1, log to the journal againLennart Poettering
We don't support journal-less systems anyway, so let's avoid the confusion.
2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
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.
2014-07-31Properly report invalid quoted stringsZbigniew Jędrzejewski-Szmek
$ systemd-analyze verify trailing-g.service [./trailing-g.service:2] Trailing garbage, ignoring. trailing-g.service lacks ExecStart setting. Refusing. Error: org.freedesktop.systemd1.LoadFailed: Unit trailing-g.service failed to load: Invalid argument. Failed to create trailing-g.service/start: Invalid argument
2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
String which ended in an unfinished quote were accepted, potentially with bad memory accesses. Reject anything which ends in a unfished quote, or contains non-whitespace characters right after the closing quote. _FOREACH_WORD now returns the invalid character in *state. But this return value is not checked anywhere yet. Also, make 'word' and 'state' variables const pointers, and rename 'w' to 'word' in various places. Things are easier to read if the same name is used consistently. mbiebl_> am I correct that something like this doesn't work mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"' mbiebl_> systemd seems to strip of the quotes mbiebl_> systemctl status shows mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint mbiebl_> which is pretty weird

2014-07-27core: only set the kernel's timezone when the RTC runs in local timeKay Sievers
We can not reliably manage any notion of local time. Every daylight saving time change or time zone change by traveling will make the time jump, and the local time might jump backwards which creates unsolvable problems with file timestamps. We will no longer tell the kernel our local time zone and leave everything set to UTC. This will effectively turn FAT timestamps into UTC timestamps. If and only if the machine is configured to read the RTC in local time mode, the kernel's time zone will be configured, but systemd-timesysnc will disable the kernel's system time to RTC syncing. In this mode, the RTC will not be managed, and external tools like Windows bootups are expected to manage the RTC's time. https://bugs.freedesktop.org/show_bug.cgi?id=81538
2014-07-20test-engine: fix access to unit load pathZbigniew Jędrzejewski-Szmek
Also add a bit of debugging output to help diagnose problems, add missing units, and simplify cppflags. Move test-engine to normal tests from manual tests, it should now work without destroying the system.
2014-07-20systemd: use pager for --test and --helpZbigniew Jędrzejewski-Szmek
2014-07-16Let config_parse open file where applicableZbigniew Jędrzejewski-Szmek
Special care is needed so that we get an error message if the file failed to parse, but not when it is missing. To avoid duplicating the same error check in every caller, add an additional 'warn' boolean to tell config_parse whether a message should be issued. This makes things both shorter and more robust wrt. to error reporting.

2014-07-07firstboot: get rid of firstboot generator again, introduce ↵Lennart Poettering
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.
2014-07-07firstboot: add new component to query basic system settings on first boot, ↵Lennart Poettering
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.
2014-07-07main: explain our /etc empty check a bit in a commentLennart Poettering
2014-07-04main: change check whether /etc is unpopulated to look for /etc/machine-idLennart Poettering
Previously, we checked whether /etc was completely empty. This makes it difficult though for container managers such as nspawn to install a small number of files (such as /etc/timezone), and have the system otherwise populate its own tree. Hence, change this by looking for /etc/machine-id, which should be a good sign whether /etc is populated or not.
2014-06-27main: uid_to_name() might fail due to OOM, protect against thatLennart Poettering
2014-06-26core: use correct format string for UIDsMichał Bartoszkiewicz
2014-06-20core: clean-up signal reset logic when reexecLennart Poettering
There's no need to save the old sigmask, if we are going to die. Let's simplify this. Also, reset all the signal handlers, so that we don't leave SIG_IGN set for some of them across reexec.
2014-06-19main: don't show help text anymore when we detect an unknown kernel cmdline ↵Lennart Poettering
value starting with "systemd." As generators and other components started to maintain their own kernel command line options this help text needed more and more exceptions and wasn't complete anyway. Fixing that would leak more information about specific generators into PID 1, which we should avoid. Given that kernel cmdline handling traditionally doesn't generate errors or show help texts, let's just remove the logic for it for systemd too.
2014-06-19main: honour rd.systemd.unit= only in the initrd, not the hostLennart Poettering
2014-06-17core: populate unit file set with preset data if we boot with empty /etcLennart Poettering
2014-06-17machine-id-setup: allow passing NULL as function argument, for simplicityLennart Poettering
2014-06-17kmod: conditionalize kmod setup on CAP_SYS_MODULE, not whether we run in a ↵Lennart Poettering
container It's generally preferrable to conditionalize on the actual ability to do something then the context we run in.
2014-06-17log: don't downgrade log level in non-PID 1 if "quiet" is passed on kernel ↵Lennart Poettering
cmdline "debug" should apply to all tools, but "quiet" only to PID1.
2014-06-16Reset signal-mask on re-exec to init=..Ruediger Oertel
Process 1 (aka init) needs to be started with an empty signal mask. That includes the process 1 that's started after the initrd is finished. When the initrd is using systemd (as it does with dracut based initrds) then it is systemd that calls the real init. Normally this is systemd again, except when the user uses for instance "init=/bin/bash" on the kernel command line.
2014-06-13core: don't complain at early boot if /etc/mtab is not the right symlinkLennart Poettering
When we boot up with an empty /etc it's ok if the symlink doesn't exist. We will create it later with tmpfiles.
2014-06-13os-release: define /usr/lib/os-release as fallback for /etc/os-releaseLennart Poettering
The file should have been in /usr/lib/ in the first place, since it describes the OS container in /usr (and not the configuration in /etc), hence, let's support os-release files in /usr/lib as fallback if no version in /etc exists, following the usual override logic. A prior commit already enabled tmpfiles to create /etc/os-release as a symlink to /usr/lib/os-release should it be missing, thus providing nice compatibility with applications only checking in /etc. While it's probably a good idea if all apps check both locations via a fallback logic, it is only necessary in the early boot process, as long as the /etc/os-release symlink has not been restored, in case we boot with an empty /etc.
2014-05-28virt: rework container detection logicLennart Poettering
Instead of accessing /proc/1/environ directly, trying to read the $container variable from it, let's make PID 1 save the contents of that variable to /run/systemd/container. This allows us to detect containers without the need for CAP_SYS_PTRACE, which allows us to drop it from a number of daemons and from the file capabilities of systemd-detect-virt. Also, don't consider chroot a container technology anymore. After all, we don't consider file system namespaces container technology anymore, and hence chroot() should be considered a container even less.
2014-05-24shared: rename hwclock.[ch] to clock-util.[ch]Kay Sievers
2014-05-22cgroups: simplify CPUQuota= logicLennart Poettering
Only accept cpu quota values in percentages, get rid of period definition. It's not clear whether the CFS period controllable per-cgroup even has a future in the kernel, hence let's simplify all this, hardcode the period to 100ms and only accept percentage based quota values.
2014-05-05core: require cgroups filesystem to be availableKay Sievers
We should no longer pretend that we can run in any sensible way without the kernel supporting us with cgroups functionality.
