2015-09-30man: update description of exit.targetZbigniew Jędrzejewski-Szmek
exit.target is now used for both system and user sessions, so remove "on user service manager exit". Also reword that paragraph: services will be killed before the manager exits, even if they do not conflict with shutdown target, but we recommend that they conflict with shutdown target so that systemd schedules them to be stopped immediately when starting to exit. In the first paragraph, containers should be mentioned last, and the more general systems first.

2015-09-29core: rework crash handlingLennart Poettering
This introduces a new systemd.crash_reboot=1 kernel command line option that triggers a reboot after crashing. This also cleans up crash VT handling. Specifically, it cleans up the configuration setting, to be between 1..63 or a boolean. This is to replace the previous logic where "-1" meant disabled. We continue to accept that setting, but only document the boolean syntax instead. This also brings the documentation of the default settings in sync with what actually happens. The CrashChVT= configuration file setting is renamed to CrashChangeVT=, following our usual logic of not abbreviating unnecessarily. The old setting stays support for compat reasons. Fixes #1300
2015-09-29core: allow setting WorkingDirectory= to the special value ~Lennart Poettering
If set to ~ the working directory is set to the home directory of the user configured in User=. This change also exposes the existing switch for the working directory that allowed making missing working directories non-fatal. This also changes "machinectl shell" to make use of this to ensure that the invoked shell is by default in the user's home directory. Fixes #1268.

2015-09-29machine-id-commit: merge machine-id-commit functionality into machine-id-setupLennart Poettering
And remove machine-id-commit as separate binary. There's really no point in keeping this separate, as the sources are pretty much identical, and have pretty identical interfaces. Let's unify this in one binary. Given that machine-id-commit was a private binary of systemd (shipped in /usr/lib/) removing the tool is not an API break. While we are at it, improve the documentation of the command substantially.
2015-09-29systemctl: make "systemctl is-system-running" return "offline" if we are not ↵Lennart Poettering
booted with systemd This sounds like the better place to expose this than in "systemd-notify --booted". Also document the so far undocumented "unknown" state the command might return. And rearrange the table of states documented to be more like the one for "is-running". Also, don't document the precise exit code of this function, just say errors are reported != 0 or > 0...

This mirrors --type=help and simplifies completion scripts. The array of states is dense, so the is no need to check if the string is null.

2015-09-21containers: systemd exits with non-zero codeAlban Crequy
When a systemd service running in a container exits with a non-zero code, it can be useful to terminate the container immediately and get the exit code back to the host, when systemd-nspawn returns. This was not possible to do. This patch adds the following to make it possible: - Add a read-only "ExitCode" property on PID 1's "Manager" bus object. By default, it is 0 so the behaviour stays the same as previously. - Add a method "SetExitCode" on the same object. The method fails when called on baremetal: it is only allowed in containers or in user session. - Add support in systemctl to call "systemctl exit 42". It reuses the existing code for user session. - Add exit.target and systemd-exit.service to the system instance. - Change main() to actually call systemd-shutdown to exit() with the correct value. - Add verb 'exit' in systemd-shutdown with parameter --exit-code - Update systemctl manpage. I used the following to test it: | $ sudo rkt --debug --insecure-skip-verify run \ | --mds-register=false --local docker://busybox \ | --exec=/bin/chroot -- /proc/1/root \ | systemctl --force exit 42 | ... | Container rkt-895a0cba-5c66-4fa5-831c-e3f8ddc5810d failed with error code 42. | $ echo $? | 42 Fixes https://github.com/systemd/systemd/issues/1290

networkd: add support for accept ra
2015-09-16cgroup: add support for net_cls controllersDaniel Mack
Add a new config directive called NetClass= to CGroup enabled units. Allowed values are positive numbers for fix assignments and "auto" for picking a free value automatically, for which we need to keep track of dynamically assigned net class IDs of units. Introduce a hash table for this, and also record the last ID that was given out, so the allocator can start its search for the next 'hole' from there. This could eventually be optimized with something like an irb. The class IDs up to 65536 are considered reserved and won't be assigned automatically by systemd. This barrier can be made a config directive in the future. Values set in unit files are stored in the CGroupContext of the unit and considered read-only. The actually assigned number (which may have been chosen dynamically) is stored in the unit itself and is guaranteed to remain stable as long as the unit is active. In the CGroup controller, set the configured CGroup net class to net_cls.classid. Multiple unit may share the same net class ID, and those which do are linked together.

2015-09-11core: refactor cpu shares/blockio weight cgroup logicLennart Poettering
Let's stop using the "unsigned long" type for weights/shares, and let's just use uint64_t for this, as that's what we expose on the bus. Unify parsers, and always validate the range for these fields. Correct the default blockio weight to 500, since that's what the kernel actually uses. When parsing the weight/shares settings from unit files accept the empty string as a way to reset the weight/shares value. When getting it via the bus, uniformly map (uint64_t) -1 to unset. Open up StartupCPUShares= and StartupBlockIOWeight= to transient units.
2015-09-10core: add support for the "pids" cgroup controllerLennart Poettering
This adds support for the new "pids" cgroup controller of 4.3 kernels. It allows accounting the number of tasks in a cgroup and enforcing limits on it. This adds two new setting TasksAccounting= and TasksMax= to each unit, as well as a gloabl option DefaultTasksAccounting=. This also updated "cgtop" to optionally make use of the new kernel-provided accounting. systemctl has been updated to show the number of tasks for each service if it is available. This patch also adds correct support for undoing memory limits for units using a MemoryLimit=infinity syntax. We do the same for TasksMax= now and hence keep things in sync here.

2015-09-06nspawn: add new .nspawn files for container settingsLennart Poettering
.nspawn fiels are simple settings files that may accompany container images and directories and contain settings otherwise passed on the nspawn command line. This provides an efficient way to attach execution data directly to containers.
2015-09-05sd-login: add new sd_pid_get_cgroup() APILennart Poettering
This adds a new sd_pid_get_cgroup() call to sd-login which may be used to query the control path of a process. This is useful for programs when making use of delegation units, in order to figure out which subtree has been delegated. In light of the unified control group hierarchy this is finally safe to do, hence let's add a proper API for it, to make it easier to use this.

The constraints we place on the pool is that it is a contiguous sequence of addresses in the same subnet as the server address, not including the subnet nor broadcast addresses, but possibly including the server address itself. If the server address is included in the pool it is (obviously) reserved and not handed out to clients.
