3936. [func] Added authoritative support for the EDNS Client
Subnet (ECS) option.
ACLs can now include "ecs" elements which specify
an address or network prefix; if an ECS option is
included in a DNS query, then the address encoded
in the option will be matched against "ecs" ACL
elements.
Also, if an ECS address is included in a query,
then it will be used instead of the client source
address when matching "geoip" ACL elements. This
behavior can be overridden with "geoip-use-ecs no;".
When "ecs" or "geoip" ACL elements are used to
select a view for a query, the response will include
an ECS option to indicate which client network the
answer is valid for.
(Thanks to Vincent Bernat.) [RT #36781]
3715. [bug] The region and city databases could fail to
initialize when using some versions of libGeoIP,
causing assertion failures when named was
configured to use them. [RT #35427]
3504. [func] Add support for ACLs based on geographic location,
using MaxMind GeoIP databases. Based on code
contributed by Ken Brownfield <kb@slide.com>.
