Ovidiu Vancea 28b009f98e dnsmasq: Listen only on loopback and disable DHCP
Dnsmasq functions as DHCP and DNS servers by default and listens on all
interfaces. This conflicts with other DHCP or DNS servers already on
the network and corrupts DNS configuration on Windows systems.

We noticed that after installing docker, the Linux system became a
magnet for DNS requests coming from Windows systems. Dnsmasq is a
dependency for lxc which is recommended for docker.

Windows periodically broadcasts DHCPInform and DHCP servers reply with
DHCPAck. If the DHCPAck from the Linux target reaches the Windows
system first, Windows changes its DNS server IP to the Linux system
running dnsmasq. Dnsmasq ends up forwarding the DNS requests to the
official DNS server and replies back the answer to the original
requestor. The Linux system transparently becomes a DNS proxy on the
subnet.

meta-networking
===============

This layer is intended to be a central point for networking-related
packages and configuration.  It should be useful directly on top of
oe-core and compliments meta-openembedded.  It should be primarily useful
to the following groups:

      - Anyone building a small networking device (eg. a home router /
        bridge / switch).

      - Anyone wanting to add network services to their device (eg.
        anything that might benefit from a small ftp/tftp server)

Dependencies
------------

This layer depends on:

URI: git://github.com/openembedded/openembedded-core.git
branch: master
revision: HEAD

For some recipes, the meta-oe layer is required:

URI: git://github.com/openembedded/meta-openembedded.git
subdirectory: meta-oe
branch: master
revision: HEAD

URI: git://github.com/openembedded/meta-openembedded.git
subdirectory: meta-python
branch: master
revision: HEAD

Maintenance
-----------

Please see the MAINTAINERS file for information on contacting the
maintainers of this layer, as well as instructions for submitting patches.
