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: 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=).

2013-06-26journalctl: highlight MESSAGE= in verbose outputZbigniew Jędrzejewski-Szmek
When looking at verbose output, additional "work" is required to pick out the interesting MESSAGE= lines from all the fields. Also, show long fields in full in verbose output mode when OUTPUT_FULL_WIDTH is specified.

2013-06-24journald: always vacuum empty offline filesZbigniew Jędrzejewski-Szmek
Corrupted empty files are relatively common. I think they are created when a coredump for a user who never logged anything before is attempted to be written, but the write does not succeed because the coredump is too big, but there are probably other ways to create those, especially if the machine crashes at the right time. Non-corrupted empty files can also happen, e.g. if a journal file is opened, but nothing is ever successfully written to it and it is rotated because of MaxFileSec=. Either way, each "empty" journal file costs around 3 MB, and there's little point in keeping them around.
2013-06-24journald: fix space limits reportingZbigniew Jędrzejewski-Szmek
Reporting of the free space was bogus, since the remaining space was compared with the maximum allowed, instead of the current use being compared with the maximum allowed. Simplify and fix by reporting limits directly at the point where they are calculated. Also, assign a UUID to the message.

2013-06-22journal-verify: allow unlinked data entriesZbigniew Jędrzejewski-Szmek
Sometimes an entry is not successfully written, and we end up with data items which are "unlinked", not connected to, and not used by any entry. This will usually happen when we write to write a core dump, and the initial small data fields are written successfully, but the huge COREDUMP= field is not written. This situation is hard to avoid, but the results are mostly harmless. Thus only warn about unused data items. Also, be more verbose about why journal files failed verification. This should help diagnose journal failure modes without resorting to a hexadecimal editor. https://bugs.freedesktop.org/show_bug.cgi?id=65235 (esp. see system.journal attached to the bug report).

2013-06-20Make sure we only show authentic coredump messagesZbigniew Jędrzejewski-Szmek
Before we only checked the MESSAGE_ID and COREDUMP_UNIT. Those are both user-controlled fields. For COREDUMP_USER_UNIT, relax the rules a bit, and also allow messages from _UID=0.
2013-06-20journal: allow callers to specify OBJECT_PID=Zbigniew Jędrzejewski-Szmek
When journald encounters a message with OBJECT_PID= set coming from a priviledged process (UID==0), additional fields will be added to the message: OBJECT_UID=, OBJECT_GID=, OBJECT_COMM=, OBJECT_EXE=, OBJECT_CMDLINE=, OBJECT_AUDIT_SESSION=, OBJECT_AUDIT_LOGINUID=, OBJECT_SYSTEMD_CGROUP=, OBJECT_SYSTEMD_SESSION=, OBJECT_SYSTEMD_OWNER_UID=, OBJECT_SYSTEMD_UNIT= or OBJECT_SYSTEMD_USER_UNIT=. This is for other logging daemons, like setroubleshoot, to be able to augment their logs with data about the process. https://bugzilla.redhat.com/show_bug.cgi?id=951627

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.
