networkd: add a basic network daemon This daemon listens for and configures network devices tagged with 'systemd-networkd'. By default, no devices are tagged so this daemon can safely run in parallel with existing network daemons/scripts. Networks are configured in /etc/systemd/network/*.network. The first .network file that matches a given link is applied. The matching logic is similar to the one for .link files, but additionally supports matching on interface name. The mid-term aim is to provide an alternative to ad-hoc scripts currently used in initrd's and for wired setups that don't change much (e.g., as seen on servers/and some embedded systems). Currently, static addresses and a gateway can be configured. Example .network file: [Match] Name=wlp2s0 [Network] Description=My Network Gateway=192.168.1.1 Address=192.168.1.23/24 Address=fe80::9aee:94ff:fe3f:c618/64

units: networkd - order after udev This way we are sure that /dev/net/tun has been given the right permissions before we try to connect to it. Ideally, we should create tun/tap devices over netlink, and then this whole issue would go away.

# dbus.service can be dropped once on kdbus, and systemd-udevd.service can be
# dropped once tuntap is moved to netlink
units: order networkd after sysctl This way networkd will correctly and race-freely inherit the default settings applied by sysctl. Suggested in issue #468.

units: make networkd pull in its own .busname unit The daemon requires the busname unit to operate (on kdbus systems), since it contains the policy that allows it to acquire its service name. This fixes https://bugs.freedesktop.org/show_bug.cgi?id=90287

networkd: exit on idle We will be woken up on rtnl or dbus activity, so let's just quit if some time has passed and that is the only thing that can happen. Note that we will always stay around if we expect network activity (e.g. DHCP is enabled), as we are not restarted on that.

networkd: drop CAP_SYS_MODULE Rely on modules being built-in or autoloaded on-demand. As networkd is a network facing service, we want to limits its capabilities, as much as possible. Also, we may not have CAP_SYS_MODULE in a container, and we want networkd to work the same there. Module autoloading does not always work, but should be fixed by the kernel patch f98f89a0104454f35a: 'net: tunnels - enable module autoloading', which is currently in net-next and which people may consider backporting if they want tunneling support without compiling in the modules. Early adopters may also use a module-load.d snippet and order systemd-modules-load.service before networkd to force the module loading of tunneling modules. This sholud fix the various build issues people have reported.

core: rename ReadOnlySystem= to ProtectSystem= and add a third value for also mounting /etc read-only Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit. With this in place we now have two neat options ProtectSystem= and ProtectHome= for protecting the OS itself (and optionally its configuration), and for protecting the user's data.

units: increase watchdog timeout to 3min for all our services Apparently, disk IO issues are more frequent than we hope, and 1min waiting for disk IO happens, so let's increase the watchdog timeout a bit, for all our services. See #1353 for an example where this triggers.
