9a05490933 cgroups: simplify CPUQuota= logic
Only accept cpu quota values in percentages, get rid of period
definition.

It's not clear whether the CFS period controllable per-cgroup even has a
future in the kernel, hence let's simplify all this, hardcode the period
to 100ms and only accept percentage based quota values.

db785129c9 cgroup: rework startup logic

95ae05c0e7 core: add startup resource control option
Similar to CPUShares= and BlockIOWeight= respectively. However only
assign the specified weight during startup. Each control group
attribute is re-assigned as weight by CPUShares=weight and
BlockIOWeight=weight after startup.  If not CPUShares= or
BlockIOWeight= be specified, then the attribute is re-assigned to each
default attribute value. (default cpu.shares=1024, blkio.weight=1000)
If only CPUShares=weight or BlockIOWeight=weight be specified, then
that implies StartupCPUShares=weight and StartupBlockIOWeight=weight.

f1f0198cb6 fsck: Allow to specify the fsck repair option in the cmdline
Some unattended systems do not have a console attached and entering
the default rescue mode will not be too helpful. Allow to specify
the "-y" option to attempt to fix all filesystem errors.

Manually verified by downloading an image.gz of e2fsprogs, using

3a67e927e3 networkd-wait-online: improve interoptability and enable by default
To make sure we don't delay boot on systems where (some) network links are managed by someone else
we don't block if something else has successfully brought up a link.

We will still block until all links we are aware of that are  managed by networkd have been
configured, but if no such links exist, and someone else have configured a link sufficiently
that it has a carrier, it may be that the link is ready so we should no longer block.

Note that in all likelyhood the link is not ready (no addresses/routes configured),
so whatever network managment daemon configured it should provide a similar wait-online
service to block network-online.target until it is ready.

The aim is to block as long as we know networking is not fully configured, but no longer. This
will allow systemd-networkd-wait-online.service to be enabled on any system, even if we don't
know whether networkd is the main/only network manager.

Even in the case networking is fully configured by networkd, the default behavior may not be
sufficient: if two links need to be configured, but the first is fully configured before the
second one appears we will assume the network is up. To work around that, we allow specifying
specific devices to wait for before considering the network up.

This unit is enabled by default, just like systemd-networkd, but will only be pulled in if
anyone pulls in network-online.target.

efe6e7d33a service: add support for reboot argument when triggered by StartLimitAction=
When rebooting with systemctl, an optional argument can be passed to the

service file and use it when the service triggers a restart.
This is useful to distinguish between manual reboots and reboots caused by
failing services.

9ea28c55a2 udev: remove seqnum API and all assumptions about seqnums
The way the kernel namespaces have been implemented breaks assumptions
udev made regarding uevent sequence numbers. Creating devices in a
namespace "steals" uevents and its sequence numbers from the host. It
confuses the "udevadmin settle" logic, which might block until util a
timeout is reached, even when no uevent is pending.

Remove any assumptions about sequence numbers and deprecate libudev's
API exposing these numbers; none of that can reliably be used anymore
when namespaces are involved.

aba496a58a networkd: smooth transition from ipv4ll to dhcp address
Currently when both ipv4ll and dhcp are enabled, ipv4ll
address (if one has been claimed) is removed when dhcp
address is aquired. This is not the best thing to do
since there might be clients unaware of the removal
trying to communicate.

This patch provides a smooth transition between ipv4ll
and dhcp. If ipv4ll address was claimed [1] before dhcp,
address is marked as deprecated. Deprecated address is still
a valid address and packets can be received on it but address
cannot be selected as a source address. If dhcp lease cannot
be extended, then ipv4ll address is marked as valid again.

[1] If there is no collision, claiming IPv4LL takes between 4 to
7 seconds.

7f8aa67131 core: remove tcpwrap support
tcpwrap is legacy code, that is barely maintained upstream. It's APIs
are awful, and the feature set it exposes (such as DNS and IDENT
access control) questionnable. We should not support this natively in
systemd.

Hence, let's remove the code. If people want to continue making use of
this, they can do so by plugging in "tcpd" for the processes they start.
With that scheme things are as well or badly supported as they were from
traditional inetd, hence no functionality is really lost.

There's really no point to send the reboot SIGINT from machinectl

makes machinectl network transparent for these verbs. And while we are
at it we can easily add a "poweroff" verb in addition to "reboot". Yay!

cc64d0175a journal-remote: HTTP(s) support
The whole tool is made dependent on µhttpd availability. It should be
easy to make the µhttpd parts conditional, but since transfer over
HTTP seems to be the primary use case, currently this is not done.

Current implementation uses nested epoll loops: sd-event is used for
the external event loop, and µhttpd uses epoll in its own
loop. Unfortunately µhttpd does not expose enough information to add
the descriptors it uses to the external event loop. This means that
starvation of other events is possible, if one of the inner µhttpd
loops is constantly busy. This means that µhttpd servers should not
be mixed with other sources.

The TLS authentication parts haven't been really tested properly, and
should not be take too seriously.

73b80ec2d9 gpt-auto-generator: automatically find the root disk of the system
When run in an initrd and no root= argument is set (or is set to
root=gpt-auto) we will automatically look for the root partition on the
same disk the EFI ESP is located on.

Since we look for swap, /home and /srv on the disk the root partition is
located on, we hence have a fully discoverable chain:

    Firmware discovers the EFI ESP partition → the initrd discovers the
    root partition → the host OS discovers swap, /home, and /srv.

Note that this requires an EFI boot loader that sets the
LoaderDevicePartUUID EFI variable, such as Gummiboot.

df31a6c0fe systemd-run: add new --property= switch that can set arbitrary properties for the unit that is created
The code for parsing these properties is shared with "systemctl
set-property", which means all the resource control settings are
immediately available.

1c231f5648 logind: make $XDG_RUNTIME_DIR a per-user tmpfs
This way each user allocates from his own pool, with its own size limit.

This puts the size limit by default to 10% of the physical RAM size but
makes it configurable in logind.conf.

6a79c58603 logind: ignore lid switch if more than 1 display is connected
Previously we expected the desktop environment to take an inhibitor
lock, but this opened a race on boot-up where logind might already be
running but no DE is active.

Hence, let's move checking for additional displays into logind. This
also opens up this logic for other DEs, given that only GNOME
implemented the inhibitor logic so far.

e66cf1a3f9 core: introduce new RuntimeDirectory= and RuntimeDirectoryMode= unit settings
As discussed on the ML these are useful to manage runtime directories
below /run for services.

df1e020461 Revert back to /var/run at a couple of problems
This partially reverts 41a55c46ab

Some specifications we want to stay compatibility actually document
/var/run, not /run, and we should stay compatible with that. In order to
make sure our D-Bus implementation works on any system, regardless if
running systemd or not, we should always use /var/run which is the
only path mandated by the D-Bus spec.

Similar, glibc hardcodes the utmp location to /var/run, and this is
exposed in _UTMP_PATH in limits.h, hence let's stay in sync with this
public API, too.

We simply do not support systems where /var/run is not a symlink → /run.
Hence both are equivalent. Staying compatible with upstream
specifications hence weighs more than cleaning up superficial
appearance.
