CVE-2015-7547 mitigation script

In response to CVE-2015-7547, we are developing this Lua script which should protect your users, at a slight risk of disrupting specific queries which naturally deliver very large responses.

Run the script below by setting: lua-dns-script=stop-cve-2015-7547.lua - or use rec_control reload-lua-script stop-cve-2015-7547.lua at runtime.

Please continue to check this page for updates.

LUA Record Type for Lua-powered DNS records for standards based fail-over and geographical load balancing

GitHub branch -> https://github.com/ahupowerdns/pdns/tree/luarec

Recently, many zone owners could not migrate away from Dyn since they were benefiting from non-standardised DNS-based failover and geographical loadbalancing features. What you see below is an attempt to get standards based but flexible equivalents of these currently proprietary features. Here is a zone:
