2016-05-27core: add cgroup memory controller support on the unified hierarchy (#3315)Tejun Heo
On the unified hierarchy, memory controller implements three control knobs - low, high and max which enables more useable and versatile control over memory usage. This patch implements support for the three control knobs. * MemoryLow, MemoryHigh and MemoryMax are added for memory.low, memory.high and memory.max, respectively. * As all absolute limits on the unified hierarchy use "max" for no limit, make memory limit parse functions accept "max" in addition to "infinity" and document "max" for the new knobs. * Implement compatibility translation between MemoryMax and MemoryLimit. v2: - Fixed missing else's in config_parse_memory_limit(). - Fixed missing newline when writing out drop-ins. - Coding style updates to use "val > 0" instead of "val". - Minor updates to documentation.

2016-05-19systemctl: restore the no-sync option for legacy halt (#3249)tblume
The sync() call on shutdown had been removed with commit 57371e5829a61e5ee6c9f98404dfc729d6c62608 together with the no-sync option for the shutdown commands. The sync call was restored in commit 4a3ad39957399c4a30fc472a804e72907ecaa4f9 but the no-sync option wasn't re-added. I think we should restore this option at least for the legacy halt command.
2016-05-18core: translate between IO and BlockIO settings to ease transitionTejun Heo
Due to the substantial interface changes in cgroup unified hierarchy, new IO settings are introduced. Currently, IO settings apply only to unified hierarchy and BlockIO to legacy. While the transition is necessary, it's painful for users to have to provide configs for both. This patch implements translation from one config set to another for configs which make sense. * The translation takes place during application of the configs. Users won't see IO or BlockIO settings appearing without being explicitly created. * The translation takes place only if there is no config for the matching cgroup hierarchy type at all. While this doesn't provide comprehensive compatibility, it should considerably ease transition to the new IO settings which are a superset of BlockIO settings. v2: - Update test-cgroup-mask.c so that it accounts for the fact that CGROUP_MASK_IO and CGROUP_MASK_BLKIO move together. Also, test/parent.slice now sets IOWeight instead of BlockIOWeight.
2016-05-18core: add support for IOReadIOPSMax and IOWriteIOPSMaxTejun Heo
cgroup IO controller supports maximum limits for both bandwidth and IOPS but systemd resource control currently only supports bandwidth limits. This patch adds support for IOReadIOPSMax and IOWriteIOPSMax when unified cgroup hierarchy is in use. It isn't difficult to also add BlockIOReadIOPS and BlockIOWriteIOPS for legacy hierarchies but IO control on legacy hierarchies is half-broken anyway, so let's leave it alone for now.

2016-05-17networkd: Add EmitRouter= option for DHCP Server (#3251)Clemens Gruber
Add an option to disable appending DHCP option 3 (Router) to the DHCP OFFER and ACK packets. This commit adds the boolean option EmitRouter= for the [DHCPServer] section in .network files. Rationale: On embedded devices, it is very useful to have a DHCP server running on an USB OTG ethernet gadget interface to avoid manual setup on the client PCs, but it should only serve IP addresses, no route(r)s. Otherwise, Windows clients experience network connectivity issues, due to them using the address set in DHCP option 3 as default gateway. Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com>

2016-05-16man: clarify that IOXyz= only applies to the unified hierarchy, and ↵Lennart Poettering
BlockIOXyz= to the legacy hierarchy With this change for each setting we say which hierarachy it applies to briefly in the first sentence of the description, plus in longer form in an extra pargraph at the end, with a recommendation for the counterpart of the option in the other hierarchy. Also adds markup and the "=" suffix to all mentioned settings.

2016-05-12Create initrd-root-device.target synchronization point (#3239)Daniel Drake
Add a synchronization point so that custom initramfs units can run after the root device becomes available, before it is fsck'd and mounted. This is useful for custom initramfs units that may modify the root disk partition table, where the root device is not known in advance (it's dynamically selected by the generators).

2016-05-09networkd: reworkd LLDP emission to allow control of propagation levelLennart Poettering
This allows selecting the propagation level of emitted LLDP packets (specifically: the destination MAC address of the packets). This is useful because it allows generating LLDP packets that optionally cross certain types of bridges. See 802.11ab-2009, Table 7-1 for details.

2016-05-05logind: enforce a limit on inhibitors we hand outLennart Poettering
For similar reasons as the recent addition of a limit on sessions. Note that we don't enforce a limit on inhibitors per-user currently, but there's an implicit one, since each inhibitor takes up one fd, and fds are limited via RLIMIT_NOFILE, and the limit on the number of processes per user.
2016-05-05logind: enforce a limit on current user sessionsLennart Poettering
We really should put limits on all resources we manage, hence add one to the number of concurrent sessions, too. This was previously unbounded, hence set a relatively high limit of 8K by default. Note that most PAM setups will actually invoke pam_systemd prefixed with "-", so that the return code of pam_systemd is ignored, and the login attempt succeeds anyway. On systems like this the session will be created but is not tracked by systemd.
2016-05-05core: add io controller support on the unified hierarchyTejun Heo
On the unified hierarchy, blkio controller is renamed to io and the interface is changed significantly. * blkio.weight and blkio.weight_device are consolidated into io.weight which uses the standardized weight range [1, 10000] with 100 as the default value. * blkio.throttle.{read|write}_{bps|iops}_device are consolidated into io.max. Expansion of throttling features is being worked on to support work-conserving absolute limits (io.low and io.high). * All stats are consolidated into io.stats. This patchset adds support for the new interface. As the interface has been revamped and new features are expected to be added, it seems best to treat it as a separate controller rather than trying to expand the blkio settings although we might add automatic translation if only blkio settings are specified. * io.weight handling is mostly identical to blkio.weight[_device] handling except that the weight range is different. * Both read and write bandwidth settings are consolidated into CGroupIODeviceLimit which describes all limits applicable to the device. This makes it less painful to add new limits. * "max" can be used to specify the maximum limit which is equivalent to no config for max limits and treated as such. If a given CGroupIODeviceLimit doesn't contain any non-default configs, the config struct is discarded once the no limit config is applied to cgroup. * lookup_blkio_device() is renamed to lookup_block_device().

networkd: add support to set route table 1. add support to configure the table id. if id is less than 256 we can fit this in the header of route as netlink property is a char. But in kernel this proepty is a unsigned 32. Hence if greater that 256 add this as RTA_TABLE attribute. 2. we are not setting the address family now. Now set this property.

2016-05-02core: move enforcement of the start limit into per-unit-type code againLennart Poettering
Let's move the enforcement of the per-unit start limit from unit.c into the type-specific files again. For unit types that know a concept of "result" codes this allows us to hook up the start limit condition to it with an explicit result code. Also, this makes sure that the state checks in clal like service_start() may be done before the start limit is checked, as the start limit really should be checked last, right before everything has been verified to be in order. The generic start limit logic is left in unit.c, but the invocation of it is moved into the per-type files, in the various xyz_start() functions, so that they may place the check at the right location. Note that this change drops the enforcement entirely from device, slice, target and scope units, since these unit types generally may not fail activation, or may only be activated a single time. This is also documented now. Note that restores the "start-limit-hit" result code that existed before 6bf0f408e4833152197fb38fb10a9989c89f3a59 already in the service code. However, it's not introduced for all units that have a result code concept. Fixes #3166.
