Thanks Tony,
Thanks for the comments. Responses are inline below in my tracking
notes below.
14.9 DONE Tony Finch in a sub thread to Paul
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Some questions about the intended meanings...
14.9.1 DONE 3.6. Extended DNS Error Code 5 - DNSSEC Indeterminate
------------------------------------------------------------------
If I remember correctly, there isn't a consistent definition of what
"indeterminate" means. Perhaps it's worth adding a reference to the
intended definition.
[ actually maybe all the codes could have citations to where the error
cases are mentioned in existing specifications, perhaps with a comment
that the citations are not intended to be exhausive ]
+ Response: good point. I'll use a reference to 4035. We'll have to
collect references for the rest... That's a good (and painful)
idea.
14.9.2 DONE 3.5. Extended DNS Error Code 4 - Forged Answer
-----------------------------------------------------------
3.16. Extended DNS Error Code 15 - Blocked 3.17. Extended DNS Error
Code 16 - Censored 3.19. Extended DNS Error Code 18 - Filtered
I don't understand the shades of meaning that these are supposed to
distinguish.
wrt "filtered", the description implies vaguely RPZ flavoured
filtering, but it mentions a REFUSED RCODE which isn't what a sensible
implementation would use for that purpose, so I am more confused.
3.18. Extended DNS Error Code 17 - Prohibited
If I understand correctly, the four above are about the qname whereas
this is about the client? The ordering is a bit confusing.
+ Response: Those three codes were supplied in a previous comment
round and they are supposed to indicate policies being applied from
different sources. Can you check the new text of them to see if
they are more understandable now?
14.9.3 DONE 3.21. Extended DNS Error Code 20 - Lame
----------------------------------------------------
This needs to be split into two: server doesn't know about the zone
queried for (typically RCODE=REFUSED), and server knows about the zone
but it has expired (typically RCODE=SERVFAIL).
Resolvers handling RD=0 queries typically answer from cache or would
answer REFUSED/Prohibited, I would have thought.
+ Response: I created an "Invalid Data" error code to handle this.
Does this work for you?
