Unbound+DHCP (server of your choice) should be able to replicate
a lot of what dnsmasq provides. With this change set Unbound
still works with dnsmasq, but also it can work with a plain
DHCP server. Features have been added within the UCI itself
to act like dnsmasq.
- alone: name each interface relative to router hostname
- alone: prevent upstream leakage of your domain and '.local'
- dnsmasq: use dnsmasq UCI to configure forwarding clauses
- dhcp: work with odhcpd as example of companion DHCP-DNS
- dhcp: convert DHCPv4 leases into EUI64 SLAAC for DNS records
- all: enable encrypted remote unbound-control using splice conf
- all: allow user spliced conf-files for hybrid UCI and manual conf
-- 'unbound_srv.conf' will be spliced into the 'server:' clause
-- 'unbound_ext.conf' will add clauses to the end, example 'forward:'
README HOW TO for dnsmasq-in-serial, dnsmasq-in-parallel, and
unbound-with-odhcpd have better/added UCI starters. HOW TO for
including unbound_srv.conf and unbound_ext.conf are added.
Document new UCI: add_local_fqdn, add_wan_fqdn, dhcp4_slaac6,
dhcp_link, domain, and domain_type

This is bare minimum change in 'unbound.sh' and
'dnsmasq.sh' to migrate the UCI option set for
more flexibility. The boolean(s) to link to
dnsmasq are being changed to a state to include
odhcpd. It is executable but a small step for
clear change management.

The UCI for Unbound already links to dnsmasq, but what
if with Unbound, we want to configure a plain dhcp server.
Most servers can call a script for lease events. That
script can then formulate DNS records and load them
with unbound-control (dependency).
The files added here work with OpenWRT/LEDE odhcpd, such
that it can be run alone. They can be used as examples
for any dhcp server. 'odhcpd.sh' is to be called by
odhcpd when a lease event occurs. 'odhcpd.awk' is called
internal to the shell script. The awk script handles
any tricky reformating that may be required.
/etc/config/dhcp
config odhcpd 'odhcpd'
option leasetrigger '/usr/lib/unbound/odhcpd.sh'

If Unbound was disabled and at later time enabled, then it
would operate in DNSSEC less-secure mode. When NTP hotplug
was called, the timestamp file was not updated. This was
found testing Unbound vs other tools (bind, dnsmasq).

- History: prior to package 1.5.10-3 /var/lib/unbound was not used
- History: prior to package 1.5.10-4 no UCI scripts were provided
- Problem: UCI 'option manual_conf 1' only copied unbound.conf and root.key
- Problem: power users that had complex file nests cannot use this
- Fix: README.md includes instructions for /var/lib/unbound jail
- Fix: unbound.sh copies ALL of /etc/unbound for 'option manual_conf 1'

Until now unbound was always running as root by default. A DNS resolver can
easily run under a non-privileged user.

The custom list of DNS root servers provided with the package is not necessary.

This is an import of the net/unbound package from Subversion
revision 40658 (May 2, 2014). The only change is the addition of
PKG_LICENSE, PKG_LICENSE_FILE and PKG_MAINTAINER to Makefile.
Unbound 1.4.22 is the current upstream release.
