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.

We expect the CPE_NAME to be formatted in URI binding syntax. Make that clear in the documentation. Furthermore, the CPE-spec has been taken over by NIST, so adjust the links as well. Reported by: Ben Harris <bjh21@cam.ac.uk>
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.
2015-09-04sd-login: rework error handlingLennart Poettering
Makre sure we always return sensible errors for the various, following the same rules, and document them in a comment in sd-login.c. Also, update all relevant man pages accordingly.
2015-09-04man: always use the same example in nss module documentationLennart Poettering
Show the same recommended example file in all three man pages, just highlight the different, relevant parts. This should be less confusing for users, and clarify what we actually recommend how /etc/nsswitch.conf is set up.

2015-08-31networkd: dhcp-server - allow configuration of the poolTom Gundersen
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.

2015-08-31cgtop: recursively count cgroup member tasksLennart Poettering
When showing the number of tasks in a cgroup, recursively count tasks in child cgroups and include them in the number. This ensures that the number of tasks is cummulative the same way as memory, cpu and IO resources are. Old behaviour can be restored by passing the new --recursive=no switch.

2015-08-28nspawn: add (no)rbind option to --bind and --bind-roEugene Yakubovich
--bind and --bind-ro perform the bind mount non-recursively. It is sometimes (often?) desirable to do a recursive mount. This patch adds an optional set of bind mount options in the form of: --bind=src-path:dst-path:options options are comma separated and currently only "rbind" and "norbind" are allowed. Default value is "rbind".

2015-08-28cgtop: major modernizationsLennart Poettering
In preparation of the unified cgroup support, let's clean up cgtop: a) rework time code to be based on "nsec_t" rather than "struct timespec" b) Introduce long option --order= for selecting ordering c) count number of processes only in the main hierarchy, don't bother with the controller hierarchies. We don't allow orthogonal hierarchies in systemd anymore, hence there's no point to check the other hierarchies. d) Deal with non-monotonic cpuacct values (see #749) e) When sorting groups, don't do prefix compare when ordering by number of tasks, since this is not accumulative for all children. f) Actually make --cpu without parameter work g) Don't output control characters when we get them as input. Fixes #749.

2015-08-24core: optionally create LOGIN_PROCESS or USER_PROCESS utmp entriesLennart Poettering
When generating utmp/wtmp entries, optionally add both LOGIN_PROCESS and INIT_PROCESS entries or even all three of LOGIN_PROCESS, INIT_PROCESS and USER_PROCESS entries, instead of just a single INIT_PROCESS entry. With this change systemd may be used to not only invoke a getty directly in a SysV-compliant way but alternatively also a login(1) implementation or even forego getty and login entirely, and invoke arbitrary shells in a way that they appear in who(1) or w(1). This is preparation for a later commit that adds a "machinectl shell" operation to invoke a shell in a container, in a way that is compatible with who(1) and w(1).
