Bug fix dhcp4_slaac6 option was adding to all IP6 routes.
Filtering was added to this process to only include addresses
served from "this dhcp interface."
adblock 2.3.0 file output is now detected and automatically
integrated into Unbound local-zones. adblock deposites its
block site zone-files into /var/lib/unbound. If this is not
desired, then disable adblock or reconfigure to avoid Unbound.

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:'

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.

This patch enables support for validating ECDSA signatures, which
are being deployed more and more in DNSSEC.
Proper validating can be tested by observing the AD flag in following

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.
