Extra Extended DNS Error codes for DNSSEC status bogus
draft-carpay-extra-ede-codes-dnssec-bogus-00
Abstract
While implementing Extended DNS Errors (RFC8914) in our DNSSEC
validating resolver software Unbound, we encountered this specific
situations regarding the DNSSEC bogus status where no Extended DNS
Error were yet defined. This draft serves as a reference for code
points requests.

1. Introduction
While implementing Extended DNS Errors ([RFC8914]) in our DNSSEC
validating resolver software Unbound ([UNBOUNDPR]), we encountered
this specific situations regarding the DNSSEC bogus status where no
Extended DNS Error were yet defined.
1.1. Extended DNS Error Code 26 - Signature Wrong Size
The resolver attempted to perform DNSSEC validation, but the
signature is either smaller or larger than expected for the specified
algorithm.
1.2. Extended DNS Error Code 27 - Malformed Signer Name
The resolver attempted to perform DNSSEC validation, but the Signer's
Name Field in the signature contains a malformed signer (d)name.
1.3. Extended DNS Error Code 28 - Signer Name Out of zone
The resolver attempted to perform DNSSEC validation, but the Signer's
Name Field in the signature does not contain the zone name of the
covered RRset.
1.4. Extended DNS Error Code 29 - Signature Label Count Wrong
The resolver attempted to perform DNSSEC validation, but the number
of labels in the Signature Labels Field is incorrect.

Internet-Draft Extra DNSSEC EDE codes February 2022
1.5. Extended DNS Error Code 30 - DNSSEC Insufficient NSEC Proof
The resolver attempted to perform DNSSEC validation, but the signed
response does not have valid NSEC proof.
1.6. Extended DNS Error Code 31 - DNSSEC Unknown Protocol
The resolver attempted to perform DNSSEC validation, but found a
value not equal to 3 in the DNSKEY protocol number field as specified
by RFC4034#section-2.1.2.
2. IANA Considerations
This draft requests the assignment of a new EDE code values for the
specified EDE codes.
3. Security Considerations
As this draft only seeks to add code points to the EDE registry, the
security considerations as the same as in [RFC8914].
