2013-07-02logind: port over to use scopes+slices for all cgroup stuffLennart Poettering
In order to prepare things for the single-writer cgroup scheme, let's make logind use systemd's own primitives for cgroup management. Every login user now gets his own private slice unit, in which his sessions live in a scope unit each. Also, add user@$UID.service to the same slice, and implicitly start it on first login.

Since not all unit types know Slice= it belongs in the unit type specific unit file section.
2013-07-01core: add new "scope" unit type for making a unit of pre-existing processesLennart Poettering
"Scope" units are very much like service units, however with the difference that they are created from pre-existing processes, rather than processes that systemd itself forks off. This means they are generated programmatically via the bus API as transient units rather than from static configuration read from disk. Also, they do not provide execution-time parameters, as at the time systemd adds the processes to the scope unit they already exist and the parameters cannot be applied anymore. The primary benefit of this new unit type is to create arbitrary cgroups for worker-processes forked off an existing service. This commit also adds a a new mode to "systemd-run" to run the specified processes in a scope rather then a transient service.

2013-06-28core: add transient unitsLennart Poettering
Transient units can be created via the bus API. They are configured via the method call parameters rather than on-disk files. They are subject to normal GC. Transient units currently may only be created for services (however, we will extend this), and currently only ExecStart= and the cgroup parameters can be configured (also to be extended). Transient units require a unique name, that previously had no configuration file on disk. A tool systemd-run is added that makes use of this functionality to run arbitrary command lines as transient services: $ systemd-run /bin/ping www.heise.de Will cause systemd to create a new transient service and run ping in it.

2013-06-27dbus: make more cgroup attributes runtime settableLennart Poettering
2013-06-27dbus: add infrastructure for changing multiple properties at once on units ↵Lennart Poettering
and hook some cgroup attributes up to it This introduces two bus calls to make runtime changes to selected bus properties, optionally with persistence. This currently hooks this up only for three cgroup atributes, but this brings the infrastructure to add more changable attributes. This allows setting multiple attributes at once, and takes an array rather than a dictionary of properties, in order to implement simple resetting of lists using the same approach as when they are sourced from unit files. This means, that list properties are appended to by this call, unless they are first reset via assigning the empty list.
2013-06-27core: general cgroup reworkLennart Poettering
Replace the very generic cgroup hookup with a much simpler one. With this change only the high-level cgroup settings remain, the ability to set arbitrary cgroup attributes is removed, so is support for adding units to arbitrary cgroup controllers or setting arbitrary paths for them (especially paths that are different for the various controllers). This also introduces a new -.slice root slice, that is the parent of system.slice and friends. This enables easy admin configuration of root-level cgrouo properties. This replaces DeviceDeny= by DevicePolicy=, and implicitly adds in /dev/null, /dev/zero and friends if DeviceAllow= is used (unless this is turned off by DevicePolicy=).

2013-06-20logind: add infrastructure to keep track of machines, and move to slicesLennart Poettering
- This changes all logind cgroup objects to use slice objects rather than fixed croup locations. - logind can now collect minimal information about running VMs/containers. As fixed cgroup locations can no longer be used we need an entity that keeps track of machine cgroups in whatever slice they might be located. Since logind already keeps track of users, sessions and seats this is a trivial addition. - nspawn will now register with logind and pass various bits of metadata along. A new option "--slice=" has been added to place the container in a specific slice. - loginctl gained commands to list, introspect and terminate machines. - user.slice and machine.slice will now be pulled in by logind.service, since only logind.service requires this slice.

2013-06-17core: add new .slice unit type for partitioning systemsLennart Poettering
In order to prepare for the kernel cgroup rework, let's introduce a new unit type to systemd, the "slice". Slices can be arranged in a tree and are useful to partition resources freely and hierarchally by the user. Each service unit can now be assigned to one of these slices, and later on login users and machines may too. Slices translate pretty directly to the cgroup hierarchy, and the various objects can be assigned to any of the slices in the tree.

Also reworded a few debug messages for brevity, and added a log statement which prints out the filter at debug level: Journal filter: (((UNIT=sys-module-configfs.device AND _PID=1) OR (COREDUMP_UNIT=sys-module-configfs.device AND MESSAGE_ID=fc2e22bc6ee647b6b90729ab34a250b1) OR _SYSTEMD_UNIT=sys-module-configfs.device) AND _BOOT_ID=4e3c518ab0474c12ac8de7896fe6b154)

We want to allow clients to process an sd_bus_message on a different thread than it was received on. Since unreffing a bus message might readd some of its memfds to the memfd cache add some minimal locking around the cache.

Just as with SMACK, we don't really know if a policy has been loaded or not, as the policy interface is write-only. Assume therefore that if ima is present in securityfs that it is enabled. Update the man page to reflect that "ima" is a valid option now as well.

2013-05-06systemd-sleep: add support for freeze and standbyZbigniew Jędrzejewski-Szmek
A new config file /etc/systemd/sleep.conf is added. It is parsed by systemd-sleep and logind. The strings written to /sys/power/disk and /sys/power/state can be configured. This allows people to use different modes of suspend on systems with broken or special hardware. Configuration is shared between systemd-sleep and logind to enable logind to answer the question "can the system be put to sleep" as correctly as possible without actually invoking the action. If the user configured systemd-sleep to only use 'freeze', but current kernel does not support it, logind will properly report that the system cannot be put to sleep. https://bugs.freedesktop.org/show_bug.cgi?id=57793 https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=7e73c5ae6e7991a6c01f6d096ff8afaef4458c36 http://lists.freedesktop.org/archives/systemd-devel/2013-February/009238.html SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed since they were used in only a few places and with the addition of /etc/systemd/sleep.conf it becomes easier to just append the name of each file to the dir name.
