def: centralize definition of default timeout in one place

use #pragma once instead of foo*foo #define guards #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers

core: unified cgroup hierarchy support This patch set adds full support the new unified cgroup hierarchy logic of modern kernels. A new kernel command line option "systemd.unified_cgroup_hierarchy=1" is added. If specified the unified hierarchy is mounted to /sys/fs/cgroup instead of a tmpfs. No further hierarchies are mounted. The kernel command line option defaults to off. We can turn it on by default as soon as the kernel's APIs regarding this are stabilized (but even then downstream distros might want to turn this off, as this will break any tools that access cgroupfs directly). It is possibly to choose for each boot individually whether the unified or the legacy hierarchy is used. nspawn will by default provide the legacy hierarchy to containers if the host is using it, and the unified otherwise. However it is possible to run containers with the unified hierarchy on a legacy host and vice versa, by setting the $UNIFIED_CGROUP_HIERARCHY environment variable for nspawn to 1 or 0, respectively. The unified hierarchy provides reliable cgroup empty notifications for the first time, via inotify. To make use of this we maintain one manager-wide inotify fd, and each cgroup to it. This patch also removes cg_delete() which is unused now. On kernel 4.2 only the "memory" controller is compatible with the unified hierarchy, hence that's the only controller systemd exposes when booted in unified heirarchy mode. This introduces a new enum for enumerating supported controllers, plus a related enum for the mask bits mapping to it. The core is changed to make use of this everywhere. This moves PID 1 into a new "init.scope" implicit scope unit in the root slice. This is necessary since on the unified hierarchy cgroups may either contain subgroups or processes but not both. PID 1 hence has to move out of the root cgroup (strictly speaking the root cgroup is the only one where processes and subgroups are still allowed, but in order to support containers nicey, we move PID 1 into the new scope in all cases.) This new unit is also used on legacy hierarchy setups. It's actually pretty useful on all systems, as it can then be used to filter journal messages coming from PID 1, and so on. The root slice ("-.slice") is now implicitly created and started (and does not require a unit file on disk anymore), since that's where "init.scope" is located and the slice needs to be started before the scope can. To check whether we are in unified or legacy hierarchy mode we use statfs() on /sys/fs/cgroup. If the .f_type field reports tmpfs we are in legacy mode, if it reports cgroupfs we are in unified mode. This patch set carefuly makes sure that cgls and cgtop continue to work as desired. When invoking nspawn as a service it will implicitly create two subcgroups in the cgroup it is using, one to move the nspawn process into, the other to move the actual container processes into. This is done because of the requirement that cgroups may either contain processes or other subgroups.

manager: Do not handle SIGKILL since we can not This is a minor fix because it's not a major issue, this fix just avoid to get EINVAL error from sigaction(2). There are two signals can not handled at user space, SIGKILL and SIGSTOP even we're PID 1, trying to handle these two signals will get EINVAL error. There are two kinds of systemd instance, running as system manager or user session manager, apparently, the latter is a general user space process which can not handle SIGKILL. The special pid 1 also can not do that refer to kernel/signal.c:do_sigaction(). However, pid 1 is unkillable because the kernel did attach SIGNAL_UNKILLABLE to it at system boot up, refer to init/main.c:start_kernel() --> rest_init() --> kernel_thread() --> kernel_init() --> init_post() current->signal->flags |= SIGNAL_UNKILLABLE

Revert "sd-bus: do not connect to dbus-1 socket when kdbus is available" This reverts commit d4d00020d6ad855d65d31020fefa5003e1bb477f. The idea of the commit is broken and needs to be reworked. We really cannot reduce the bus-addresses to a single address. We always will have systemd with native clients and legacy clients at the same time, so we also need both addresses at the same time.

importd: when listing transfers, show progress percentage With this change the pull protocol implementation processes will pass progress data to importd which then passes this information on via the bus. We use sd_notify() as generic transport for this communication, making importd listen to them, while matching the incoming messages to the right transfer.
