network: don't forward DNS requests from isolated networks This is in response to: https://bugzilla.redhat.com/show_bug.cgi?id=723862 which points out that a guest on an "isolated" network could potentially exploit the DNS forwarding provided by dnsmasq to create a communication channel to the outside. This patch eliminates that possibility by adding the "--no-resolv" argument to the dnsmasq commandline, which tells dnsmasq to not forward on any requests that it can't resolve itself (by looking at its own static hosts files and runtime list of dhcp clients), but to instead return a failure for those requests. This shouldn't cause any undesirable change from current behavior, even in the case where a guest is currently configured with multiple interfaces, one of them being connected to an isolated network, and another to a network that does have connectivity to the outside. If the isolated network's DNS server is queried for a name it doesn't know, it will return "Refused" rather than "Unknown", which indicates to the guest that it should query other servers, so it then queries the connected DNS server, and gets the desired response. 2011-07-29 19:42:04 +00:00			`--except-interface lo --dhcp-option=3 --no-resolv \`
