2015-02-12core: disarm shutdown watchdog if we fail to set timeoutLennart Poettering
Better safe than sorry, if drivers are stupid, and reset immediately on device closing if the timeout could not be initialized. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=777735
2015-02-04core: don't reset log level to NOTICE if we get quiet on the kernel cmdlineLennart Poettering
quiet should really just have an effect on the stuff we dump on the console, not what we log elsewhere. Hence: debug on kernel cmdline → interpreted by every tool, turns up log levels to "debug" everywhere. quiet on kernel cmdline → interpreted only by PID 1 (and obviously the kernel) no alteration of the max log level, but turns off status output. http://lists.freedesktop.org/archives/systemd-devel/2014-December/026271.html

2015-02-01Add a snprinf wrapper which checks that the buffer was big enoughZbigniew Jędrzejewski-Szmek
If we scale our buffer to be wide enough for the format string, we should expect that the calculation was correct. char_array_0() invocations are removed, since snprintf nul-terminates the output in any case. A similar wrapper is used for strftime calls, but only in timedatectl.c.

2014-12-18core: use raw_clone instead of fork in signal handlerZbigniew Jędrzejewski-Szmek
fork() is not async-signal-safe and calling it from the signal handler could result in a deadlock when at_fork() handlers are called. Using the raw clone() syscall sidesteps that problem. The tricky part is that raise() does not work, since getpid() does not work. Add raw_getpid() to get the real pid, and use kill() instead of raise(). https://bugs.freedesktop.org/show_bug.cgi?id=86604

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: more log_*_errno() conversions, multiline callsMichal Schmidt
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.
2014-11-28treewide: more log_*_errno() conversionsMichal 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().
2014-11-27log: 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.

2014-11-14mount-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().

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.

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.

2014-08-22core: 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

2014-08-03Unify 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.

2014-07-31Reject 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

2014-07-16Let 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.
