2014-05-22core: add startup resource control optionWaLyong Cho
Similar to CPUShares= and BlockIOWeight= respectively. However only assign the specified weight during startup. Each control group attribute is re-assigned as weight by CPUShares=weight and BlockIOWeight=weight after startup. If not CPUShares= or BlockIOWeight= be specified, then the attribute is re-assigned to each default attribute value. (default cpu.shares=1024, blkio.weight=1000) If only CPUShares=weight or BlockIOWeight=weight be specified, then that implies StartupCPUShares=weight and StartupBlockIOWeight=weight.
2014-05-16core: make sure to serialize jobs for all unitsLennart Poettering
Previously we wouldn't serialize jobs for units that themselves have nothing to serialize. http://lists.freedesktop.org/archives/systemd-devel/2014-May/019051.html
2014-05-15Make sure that keys are properly removed from hashmapZbigniew Jędrzejewski-Szmek
This is a speculative fix for https://bugzilla.redhat.com/show_bug.cgi?id=1088865. Even though I cannot find a code path that where this would be an issue, for consistency, if we assume that cgroup_path might have been set before we got to unit_deserialize, we should make sure that the unit is removed from the hashmap before we free the key. This seems to be the only place where the key could be prematurely freed, leading to hashmap corruption.
2014-04-25core: expose CFS CPU time quota as high-level unit propertiesLennart Poettering
2014-03-19core: rework context initialization/destruction logicLennart Poettering
Let's automatically initialize the kill, exec and cgroup contexts of the various unit types when the object is constructed, instead of invididually in type-specific code. Also, when PrivateDevices= is set, set DevicePolicy= to closed.
2014-03-19core: when PrivateTmp= is set for a unit, make sure to order it after /tmp ↵Lennart Poettering
and /var/tmp are mounted
2014-03-18core: drop CAP_MKNOD when PrivateDevices= is setLennart Poettering
2014-03-17core, libsystemd, systemd, timedate, udev: spelling fixesMiklos Vajna
2014-03-12core: introduce system state enumLennart Poettering
The system state knows the states starting → running/degraded/maintenance → stopping, where: starting = system startup running = normal operation degraded = at least one unit is currently in failed state maintenance = rescue/emergency mode is active or queued stopping = system shutdown
2014-03-07Make tables for DEFINE_STRING_TABLE_LOOKUP consistentDaniel Mack
Bring some arrays that are used for DEFINE_STRING_TABLE_LOOKUP() in the same order than the enums they reference. Also, pass the corresponding _MAX value to the array initalizer where appropriate.
2014-03-06core: correctly unregister PIDs from PID hashtablesLennart Poettering
2014-03-05missing: if RLIMIT_RTTIME is not defined by the libc, then we need a new ↵Lennart Poettering
define for the max number of rlimits, too
2014-03-04Introduce strv_consume which takes ownershipZbigniew Jędrzejewski-Szmek
This mirrors set_consume and makes the common use a bit nicer.
2014-03-03bus: add sd_bus_track object for tracking peers, and port core over to itLennart Poettering
This is primarily useful for services that need to track clients which reference certain objects they maintain, or which explicitly want to subscribe to certain events. Something like this is done in a large number of services, and not trivial to do. Hence, let's unify this at one place. This also ports over PID 1 to use this to ensure that subscriptions to job and manager events are correctly tracked. As a side-effect this makes sure we properly serialize and restore the track list across daemon reexec/reload, which didn't work correctly before. This also simplifies how we distribute messages to broadcast to the direct busses: we only track subscriptions for the API bus and implicitly assume that all direct busses are subscribed. This should be a pretty OK simplification since clients connected via direct bus connections are shortlived anyway.

2014-02-24core: add global settings for enabling CPUAccounting=, MemoryAccounting=, ↵Lennart Poettering
BlockIOAccounting= for all units at once

2014-02-20core/unit: fix unit_add_target_dependencies() for units with no dependenciesDaniel Mack
For units without any dependencies, r needs to be initialized to 0. Otherwise, the return value of unit_add_target_dependencies() is unspecified.
2014-02-18util: generalize code that checks whether PIDs are alive or unwaited forLennart Poettering
2014-02-17core: fix property changes in transient unitsLennart Poettering
2014-02-17unit: slice dependencies should not be subject to DefaultDependenciesLennart Poettering
2014-02-17core: rework cgroup mask propagationLennart Poettering
Previously a cgroup setting down tree would result in cgroup membership additions being propagated up the tree and to the siblings, however a unit could never lose cgroup memberships again. With this change we'll make sure that both cgroup additions and removals propagate properly.
2014-02-13core: make StopWhenUnneeded work in conjunction with units that failLennart Poettering
during their start job https://bugzilla.redhat.com/show_bug.cgi?id=997031
2014-02-07core: one step back again, for nspawn we actually can't wait for cgroups ↵Lennart Poettering
running empty since systemd will get exactly zero notifications about it
2014-02-07core: allow PIDs to be watched by two units at the same timeLennart Poettering
In some cases it is interesting to map a PID to two units at the same time. For example, when a user logs in via a getty, which is reexeced to /sbin/login that binary will be explicitly referenced as main pid of the getty service, as well as implicitly referenced as part of the session scope.
2014-02-07core: don't send duplicate SIGCONT when killing unitsLennart Poettering
2014-02-07core: watch SIGCHLD more closely to track processes of units with no ↵Lennart Poettering
reliable cgroup empty notifier When a process dies that we can associate with a specific unit, start watching all other processes of that unit, so that we can associate those processes with the unit too. Also, for service units start doing this as soon as we get the first SIGCHLD for either control or main process, so that we can follow the processes of the service from one to the other, as long as process that remain are processes of the ones we watched that died and got reassigned to us as parent. Similar, for scope units start doing this as soon as the scope controller abandons the unit, and thus management entirely reverts to systemd. To abandon a unit introduce a new Abandon() scope unit method call.
2014-02-06core: only send SIGHUP when doing first kill, not when doing final sigkillLennart Poettering
2014-02-05core: don't wait for non-control/non-main processes when killing processes ↵Lennart Poettering
on the host either Since the current kernel cgroup notification logic is easily confused by existing subgroups, let's do the same thing as in containers before. and just not wait for non-control and non-main processes. This should be corrected as soon as we have sane cgroup notifications from the kernel.
2014-01-29core: in containers, don't wait for cgroup empty notifications which will ↵Lennart Poettering
never come
2014-01-29core: use a bit more PID_FMTLennart Poettering
2014-01-29core: introduce new KillMode=mixed which sends SIGTERM only to the main ↵Lennart Poettering
process, but SIGKILL to all daemon processes This should fix some race with terminating systemd --user, where the system systemd instance might race against the user systemd instance when sending SIGTERM.
2014-01-27core: require mounts for the root and working directoriesZbigniew Jędrzejewski-Szmek
We know that launching a unit will fail if some required directories haven't been mounted yet. There's no point in starting it just to have it fail even before it gets a chance to run.
2014-01-27core: simplify check for path absolutenessZbigniew Jędrzejewski-Szmek

2013-12-14Add more _printf_'s for format-nonliteralsThomas Hindoe Paaboel Andersen
Clang is a bit more strict wrt format-nonliterals: http://clang.llvm.org/docs/LanguageExtensions.html#format-string-checking Adding these extra printf attributes also makes gcc able to find more problems. E.g. this patch uncovers a format issue in udev-builtin-path_id.c Some parts looked intetional about breaking the format-nonliteral check. I added some supression for warnings there.
2013-12-06Get rid of our reimplementation of basenameZbigniew Jędrzejewski-Szmek
The only problem is that libgen.h #defines basename to point to it's own broken implementation instead of the GNU one. This can be fixed by #undefining basename.
2013-12-02systemd: treat reload failure as failureZbigniew Jędrzejewski-Szmek
systemctl reload "suceeded" on stopped units, but it is documented to fail in this case. https://bugzilla.redhat.com/show_bug.cgi?id=1036845

2013-11-20core: convert PID 1 to libsystemd-busLennart Poettering
This patch converts PID 1 to libsystemd-bus and thus drops the dependency on libdbus. The only remaining code using libdbus is a test case that validates our bus marshalling against libdbus' marshalling, and this dependency can be turned off. This patch also adds a couple of things to libsystem-bus, that are necessary to make the port work: - Synthesizing of "Disconnected" messages when bus connections are severed. - Support for attaching multiple vtables for the same interface on the same path. This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus calls which used an inappropriate signature. As a side effect we will now generate PropertiesChanged messages which carry property contents, rather than just invalidation information.
2013-11-16Fix RemainAfterExit services keeping a hold on consoleOlivier Brunel
When a service exits succesfully and has RemainAfterExit set, its hold on the console (in m->n_on_console) wasn't released since the unit state didn't change.

If there are no more jobs on console, no need/we shouldn't disable output.
2013-11-08Remove dead code and unexport some callsLennart Poettering
"make check-api-unused" informs us about code that is not used anymore or that is exported but only used internally. Fix these all over the place.
