Subject: [dnsext] [Editorial Errata Reported] RFC6672 (5298)
Precedence: list

The following errata report has been submitted for RFC6672,
"DNAME Redirection in the DNS".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata/eid5298

--------------------------------------
Type: Editorial
Reported by: Pieter Lexis <pieter.lexis@powerdns.com>

Section: 5.3.4.2

Original Text
-------------
   ;; Header: QR AA RCODE=3(NXDOMAIN)
   ;; OPT PSEUDOSECTION:
   ; EDNS: version: 0, flags: do; udp: 4096

   ;; Question
   cee.example.com. IN A
   ;; Authority
   bar.example.com. NSEC dub.example.com. A DNAME
   bar.example.com. RRSIG NSEC [valid signature]

Corrected Text
--------------
   ;; Header: QR AA RCODE=3(NXDOMAIN)
   ;; OPT PSEUDOSECTION:
   ; EDNS: version: 0, flags: do; udp: 4096

   ;; Question
   cee.example.com. IN A
   ;; Authority
   bar.example.com. NSEC dub.example.com. A DNAME RRSIG NSEC
   bar.example.com. RRSIG NSEC [valid signature]

Notes
-----
The NSEC record in the original text would in no case be valid as it denies it's own existence and the existence of the RRSIG, while the text indicates that " the validator can see that it is a BOGUS reply from an attacker that collated existing records from the DNS to create a confusing reply". This indicates that NSEC and RRSIG should be set in the NSEC bitmap

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
