2013-07-11loginctl: suppress cgroup tree output if cgroup is emptyLennart Poettering
same for machinectl
2013-07-11loginctl: restore cgroup display for status outputLennart Poettering
Same for machinectl.
2013-07-10user-sessions: rely on PID 1 to kill sessionsLennart Poettering
As we want to centralized cgroup access we should stop killing the user sessions directly from the systemd-user-sessions service. Instead, rely on PID 1 doing this by adding the right ordering dependencies to the session scope units.
2013-07-10logind: when creating the scope job fails, return this immediately to the ↵Lennart Poettering
client that wants to register the session Otherwise we'll hanging for the job to finish without any job existing. Similar, for machined.
2013-07-10logind: don't misunderstand UnitRemoved signals during reloadingLennart Poettering
When PID 1 reloads the units logind/machined will see UnitRemoved signals for all units. Instead of trusting these immediately, let's check the actual unit state before considering a unit gone, so that reloading PID 1 is not mistaken as the end of all sessions.

2013-07-05tests: add tests for string lookup tablesZbigniew Jędrzejewski-Szmek
The tests check if the tables have entries for all values in the enum, and that the entries are unique.

2013-07-02machined: split out machine registration stuff from logindLennart Poettering
Embedded folks don't need the machine registration stuff, hence it's nice to make this optional. Also, I'd expect that machinectl will grow additional commands quickly, for example to join existing containers and suchlike, hence it's better keeping that separate from loginctl.
2013-07-02libsystemd-logind: fix detection of session/user/machine of a PIDLennart Poettering
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.
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: make ListMachines bus call publicLennart Poettering
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.

2013-06-10Use stdint.h macros instead of casts to print uint64_t valuesZbigniew Jędrzejewski-Szmek
Casts are visually heavy, and can obscure unwanted truncations.
2013-06-09Allow for the use of @ in remote host callsDaniel Wallace
Without this you have to use %40 with the -H flag because dbus doesn't like the @ sign being unescaped.

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.
2013-05-02Add __attribute__((const, pure, format)) in various placesZbigniew Jędrzejewski-Szmek
I'm assuming that it's fine if a _const_ or _pure_ function calls assert. It is assumed that the assert won't trigger, and even if it does, it can only trigger on the first call with a given set of parameters, and we don't care if the compiler moves the order of calls.
2013-05-01cgls: add --machine/-MZbigniew Jędrzejewski-Szmek
cg_get_machine_path is modified to include the escaped machine name + ".nspawn" if the machine argument is nonnull.

2013-04-24logind: properly enumerate user/session cgroups under their new suffixed namesLennart Poettering
2013-04-22cgroup: make sure all our cgroup objects have a suffix and are properly escapedLennart Poettering
Session objects will now get the .session suffix, user objects the .user suffix, nspawn containers the .nspawn suffix. This also changes the user cgroups to be named after the numeric UID rather than the username, since this allows us the parse these paths standalone without requiring access to the cgroup file system. This also changes the mapping of instanced units to cgroups. Instead of mapping foo@bar.service to the cgroup path /user/foo@.service/bar we will now map it to /user/foo@.service/foo@bar.service, in order to ensure that all our objects are properly suffixed in the tree.

bus_error and bus_error_message_or_strerror dit almost exactly the same, so use only one of them and place it in dbus-common.
2013-04-17Report about syntax errors with metadataZbigniew Jędrzejewski-Szmek
The information about the unit for which files are being parsed is passed all the way down. This way messages land in the journal with proper UNIT=... or USER_UNIT=... attribution. 'systemctl status' and 'journalctl -u' not displaying those messages has been a source of confusion for users, since the journal entry for a misspelt setting was often logged quite a bit earlier than the failure to start a unit.

2013-04-16nspawn: introduce the new /machine/ tree in the cgroup tree and move ↵Lennart Poettering
containers there Containers will now carry a label (normally derived from the root directory name, but configurable by the user), and the container's root cgroup is /machine/<label>. This label is called "machine name", and can cover both containers and VMs (as soon as libvirt also makes use of /machine/). libsystemd-login can be used to query the machine name from a process. This patch also includes numerous clean-ups for the cgroup code.

2013-04-15core: always create /user and /machine top-level cgroup dirsLennart Poettering
This allows clients to put inotify watches on these trees to watch for state changes, without having to wait until these dirs are created. This introduces the new top-level /machine cgroup dir as canonical location where OS containers and VMs shall be located (as discussed with the libvirt folks).

2013-04-11errno is positiveZbigniew Jędrzejewski-Szmek
Make sure we compare errno against positive error codes. The ones in hwclock.c and install.c can have an impact, the rest are unlikely to be hit or in code that isn't widely used. Also check that errno > 0, to help gcc know that we are returning a negative error code.
2013-04-10logind: avoid creating stale session state filesFedora systemd team
There were old session state files accumulating in /run/systemd/session. They confused e.g. "reboot", which thought there were still users logged in. The files got created like this: session_stop(Session *s) -> ... unlink(s->state_file); ... seat_set_active(s->seat, NULL) -> session_save(...); /* re-creates the state file we just unlinked */ Fix it simply by clearing the s->started flag earlier to prevent any further writes of the state file (session_save() checks the flag).
