a543cb9a34 dhcp4d: add header describing whether lease is active
Should be interpreted by the DHCP server so that other programs don’t need to
hard-code the lease time.

41985d6378 dhcp4d: reduce lease period to 20 minutes
This forces devices to renew the lease more often, which is nice when you want
to tie home automation behavior to DHCP lease validity.

fa82132962 dhcp4d: add HostnameOverride field
This can be used to permanently override a hostname, regardless of whether the
lease is static or not. We use a separate field because we want devices to be
able to change their hostname themselves, until we override it.

3dad1e9a23 dhcp4: use the configured (not the current) MAC address
This fixes a race where dhcp4 started before netconfigd had a chance to change
the hardware address on the uplink0 interface.

fiber7’s port security feature may result in an about hour-long internet outage
without this commit.

66942bd4f7 dns: steer traffic toward the most response upstream
There is not much of a difference between IPv4 and IPv6 on my fiber7 link, but
in other networks, there might well be.

For my connection, this commit results in hitting different upstreams all the
time because the list isn’t stable. But, this is the opposite of a problem: we
are spreading the DNS query load over all configured IPs, as good netizen do.

bd8fc63b0e dns: implement per-DHCP-lease dyndns
The HTTP API is easy to use from the command line or from Go:

% curl --data "host=sub&ip=192.168.33.44" -4 http://router7:8053/dyndns
ok
% host sub.$(hostname)
sub.midna has address 192.168.33.44

This can be used in combination with https://github.com/gokrazy/gdns

b923f145a5 dhcp4d: don’t incorrectly _offer_ reused addresses
Turns out a5d9e03dd3212f7f0c11dd856b308a16a58a3cdf was not entirely sufficient:
even though reused addresses would not be handed out anymore, they would still
be offered, which results in the client not being able to obtain an address.

ec4f1f4dc5 netconfig: implement WireGuard support
To set up a tunnel, create a /perm/wireguard.json as illustrated in
netconfig_test.go, and don’t forget to adjust your /perm/interfaces.json with
the address configuration for the WireGuard tunnel.

Note that static routes cannot currently be configured, so the usefulness is
limited. If you have a use-case you’d like to see covered, please explain it in
https://github.com/rtr7/router7/issues/14
