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

networkd: allow networkd to start in early boot With the previous improvements, networkd.service's "After=dbus.service" can now be dropped. That ordering effectively forced networkd.service to run in late boot only (dbus.service was rejected to run in early boot in https://bugs.freedesktop.org/show_bug.cgi?id=98254). Fixes #4504

units: further lock down our long-running services Let's make this an excercise in dogfooding: let's turn on more security features for all our long-running services. Specifically: - Turn on RestrictRealtime=yes for all of them - Turn on ProtectKernelTunables=yes and ProtectControlGroups=yes for most of them - Turn on RestrictAddressFamilies= for all of them, but different sets of address families for each Also, always order settings in the unit files, that the various sandboxing features are close together. Add a couple of missing, older settings for a numbre of unit files. Note that this change turns off AF_INET/AF_INET6 from udevd, thus effectively turning of networking from udev rule commands. Since this might break stuff (that is already broken I'd argue) this is documented in NEWS.

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.

Makefile.am: link dbus-org.freedesktop.network1 alias in /etc This makes dbus-org.freedesktop.network1.service like dbus-org.freedesktop.resolve1.service. When systemd-networkd.service is disabled, the alias is also removed.

units: make enablement of s-n-wait-online.service follow systemd-networkd.service (#5635) In 58a6dd15582c038a25bd7059435833943e2e4617 s-n-wait-online.service was added to presets to synchronize the presets with the state after installation. But it is harmful to have s-n-wait-online.service enabled when s-n.service is disabled, because s-n-wait-online.service has Requsite=s-n.service and cannot be activated. Thus remove s-n-wait-online.service from presets again, and let it be enabled whenever s-n.service is enabled. During installation we create enablement symlinks by hand, and since s-n.service is enabled, s-n-w-o.service should be enabled too, so the symlink should still be created during installation. https://bugzilla.redhat.com/show_bug.cgi?id=1433459#c15

# We want to enable systemd-networkd-wait-online.service whenever this service
