rfkill was subsumed by util-linux in 2017 [1], and the upstream has not
been updated in over 5 years [2]. This package shadows the rfkill from
util-linux, so it can be completely removed with no breaking changes,
because util-linux is in the base package set in nixos/system-path.

This fixes a regression from 993baa587c which requires
networking.hostName to be a valid DNS label [0].
Unfortunately we missed the fact that the hostnames may also be empty,
if the user wants to obtain it from a DHCP server. This is even required
by a few modules/images (e.g. Amazon EC2, Azure, and Google Compute).

The `networking.interfaces.<name?>.proxyARP` option previously mentioned it would also enable IPv6 forwarding and `proxy_ndp`.
However, the `proxy_ndp` option was never actually set (the non-existing `net.ipv6.conf.proxy_arp` sysctl was set
instead). In addition `proxy_ndp` also needs individual entries for each ip to proxy for.
Proxy ARP and Proxy NDP are two different concepts, and enabling the latter
should be a conscious decision.
This commit removes the broken NDP support, and disables explicitly
enabling IPv6 forwarding (which is the default in most cases anyways)
Fixes#62339.
Systemd dependencies for scripted mode
were refactored according to analysis in #34586.
networking.vswitches can now be used with systemd-networkd,
although they are not supported by the daemon, a nixos receipe
creates the switch and attached required interfaces (just like
the scripted version).
Vlans and internal interfaces are implemented following the
template format i.e. each interface is
described using an attributeSet (vlan and type at the moment).
If vlan is present, then interface is added to the vswitch with
given tag (access mode). Type internal enabled vswitch to create
interfaces (see openvswitch docs).
Added configuration for configuring supported openFlow version on
the vswitch
This commit is a split from the original PR #35127.
We don't want to ignore config that can mess up machines. In general
this should always fail evaluation, as you think you are changing
behaviour and don't, which can easily create run-time errors we can
catch early.
This is a refactor of how resolvconf is managed on NixOS. We split it
into a separate service which is enabled internally depending on whether
we want /etc/resolv.conf to be managed by it. Various services now take
advantage of those configuration options.
We also now use systemd instead of activation scripts to update
resolv.conf.
NetworkManager now uses the right option for rc-manager DNS
automatically, so the configuration option shouldn't be exposed.
1. Simplify the command by reading directly from /etc/machine-id which
is already a random, lower-case hex string
2. Previously, the command output could be too short because of missing
leading digits. This is now fixed.
With a config like
{
networking.interfaces."lo".ip4 = [
{ address = "10.8.8.8"; prefixLength = 32; }
];
}
a nixos-rebuild switch would take a long time, and you'd see:
$ systemctl list-jobs

systemd[1]: Timed out waiting for device sys-subsystem-net-devices-lo.device.
This removes the device dependency for `lo` and fixes this bug.
Closes#7227
