54683f0f9b udev: net_id - support predictable ifnames on virtio buses
Virtio buses are undeterministically enumerated, so we cannot use them as a basis
for deterministic naming (see bf81e792f3). However, we are guaranteed that there
is only ever one virtio bus for every parent device, so we can simply skip over
the virtio buses when naming the devices.

d06673212e core: rework when we kill with which signal
When the user wants to explicitly send our own PID a signal, then do so.

Don't follow up SIGABRT with a SIGHUP if send_sighup is enabled. At that
point the process should have segfaulted, hence there's no point in
following up with a SIGHUP.

Send only termination signals to ourselves, never KILL or ABRT signals.

b821a397c0 unit: small clean-ups
Always say when we ignore errors. Cast calls whose return value we
knowingly ingore to (void). Use "bool" where we actually mean a boolean,
even if we return it as an int later on.

5fe8876b32 core: when looking for the unit for a process, look at the PID hashmaps first
It's cheaper that going to cgroupfs, and also usually the better choice
since it's not racy and can map PIDs even if they were moved to a
different unit.

6f883237f1 cgroup: drop "ignore_self" argument from cg_is_empty()
In all cases where the function (or cg_is_empty_recursive()) ignoring
the calling process is actually wrong, as a process keeps a cgroup busy
regardless if its the current one or another. Hence, let's simplify
things and drop the "ignore_self" parameter.

e9db43d591 units: enable waiting for unit termination in certain cases
The legacy cgroup hierarchy does not support reliable empty
notifications in containers and if there are left-over subgroups in a
cgroup. This makes it hard to correctly wait for them running empty, and
thus we previously disabled this logic entirely.

With this change we explicitly check for the container case, and whether
the unit is a "delegation" unit (i.e. one where programs may create
their own subgroups). If we are neither in a container, nor operating on
a delegation unit cgroup empty notifications become reliable and thus we
start waiting for the empty notifications again.

This doesn't really fix the general problem around cgroup notifications
but reduces the effect around it.

(This also reorders #include lines by their focus, as suggsted in
CODING_STYLE. We have to add "virt.h", so let's do that at the right
place.)

Also see #317.

957c3cf97c unit: suppress unnecessary cgroup empty check
Rework the "service is good" check, to only check the cgroup state if we
really need to instead of always.

This allows us to suppress going to the cgroupfs for an empty check for
the majority of services.

No functional change.

fc60d8153c sd-login: improve error handling
let's return ENXIO whenever we don't know something rather than ENOENT.

7577e5181a logind: Listen to WMI hotkeys to catch SW_DOCK state/events
On Dell and HP laptops the dock state/events (SW_DOCK) come from the "{Dell,HP}
WMI hotkeys" input devices. Tag them as power-switch so that login actually
considers them. Use a general match in case this affects other vendors, too.

Thanks to Andreas Schultz for debugging this!

d4ebeb4fb3 core: Use extract_first_word in config_parse_join_controllers
Related to the TODO item to replace FOREACH_WORD_QUOTED with it.

Tested by setting `JoinControllers=cpu,cpuacct,memory net_cls,blkio' in
/etc/systemd/system.conf, rebooting the system with the patched binaries
and checking that the desired setup was created by inspecting the
entries under /sys/fs/cgroup.

No regressions observed in test cases.

9b3a67c55b networkd: dhcp-server - allow configuration of the pool
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.

Merge sd_dhcp_server_set_address() and sd_dhcp_server_set_lease_pool() into

on the order they are called in. The flexibility is not needed, so let's
just do this in one call.

3df49c2877 login: support user-bus on dbus1
dbus-1.10 was just released, including systemd units to run
`dbus-daemon --session` as systemd user unit. This allows using a
user-bus with dbus1, just like we do per default with kdbus.

All the dbus libraries have already been fixed long ago to use the
user-bus as default. Hence, there's no need to set
DBUS_SESSION_BUS_ADDRESS= if we use the user-bus. However, gdm and
friends continue to spawn a session bus if this variable is not set
(instead of checking for the existence of the user-bus). Hence, we force
the user-bus, if it is available, in pam_systemd. Once gdm and friends
are fixed, we can continue to drop this again. However, that might take
a while.

With this in place, all that is needed to make the user-bus work is:
    `systemctl --global enable dbus.socket`

If dbus.socket is not enabled, the legacy session-bus is still used.

3cb5beea0c cgtop: recursively count cgroup member tasks
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.
