Things we will not do but hope other people will:
- Ports to NetBSD, OpenBSD, AIX
Projects we will be working on, but would like help for:
Big things:
- - Add recursion
-
- new plan
Like in the old days but with a twist - additional processing is done on a
best-effort basis by a non-rd packet sent to syncres. This means we can stay
lazy for far longer!
TODO:
- learn syncres not to expire its roots
- put a watch on that
learn syncres to load its roots from disk too or at completime
- be able to reduce logging
get a way to nuke the cache/parts of the cache
- learn syncres that it should serve answers from its cache
- immediately on a non-rd query
-
-
-
-
-How will this work. Anything that has an RD bit goes to syncres. We need to
-send 5 things: "qname, qtype, socket on which to send the answer,id,flags".
-PowerDNS then forgets all about it.
-
-The recursor receives these questions and goes prowling for the right
-answers. In this, it uses the main PDNS query cache. So we need either a
-full socket to communicate with or two pipes.
-
-Communications can be a stream, but access must be strictly serialized!
-
-Each query 'upwards' consists of a marker and a tuple, PDNS replies with
-serialized DNSResourceRecords, ending with an empty line.
-
-typical communication might be:
-
- qdomain qt socket id remote
--> www.powerdns.com 1 10 123 5.4.3.2
-<- Q: www.powerdns.com CNAME
--> .
-<- Q: www.powerdns.com A
--> .
-<- Q: www.powerdns.com NS
--> .
-<- Q: powerdns.com NS
--> .
-<- Q: com NS
--> COM|NS|A.GTLD-SERVERS.NET..
--> COM|NS|B.GTLD-SERVERS.NET..
--> .
-<- Q: A.GTLD-SERVERS.NET A
--> A.GTLD-SERVERS.NET|A|1.2.3.4
-<- A: powerdns.com 5
-<- powerdns.com|NS|dns-eu1.powerdns.net
-<- powerdns.com|NS|dns-us1.powerdns.net
-<- .
-
- qdomain qtype socket id remote rcode
-<- P: www.powerdns.com 1 10 123 5.4.3.2 0 <- reply packet
-<- www.powerdns.com|A|1.2.3.4
-<- powerdns.com|NS|dns-eu1.powerdns.net
-<- powerdns.com|NS|dns-us1.powerdns.net
-<.
-
-
-
- Answers pushed upwards are inserted in the query cache with a
-'unauth' flag.
-
- so, we need a syncres communicator which is executed with as
-parameter the fd it will find a socket on for its perusal.
-
-
-
- Add support for TSIG

This version is almost entirely about recursion with major changes to both the pdns recursor, which is renamed to
'<filename>pdns_recursor</filename>' and to the main PowerDNS binary to make it interact better with the recursing component.
