Hi there all,

As part of the Great Errata Cleanup of 2024, I'm going through reported
Errata and trying to close them.
I'm just dealing with the ones that I can do myself, but there are some
which I need WG input on.

I'd like to get feedback by Monday Jan 29th, otherwise I'll just go with my
proposed resolutions below.

Errata: https://www.rfc-editor.org/errata/eid7689


I don't really think that the original RFC is *wrong*, but it could be
clearer.

It uses 'dig' as the testing mechanism, and says:

Check that DO=1 queries work (EDNS supported):¶
<https://www.rfc-editor.org/rfc/rfc8906#section-8.2.8-3>

dig +nocookie +edns=0 +noad +norec +dnssec soa $zone @$server

expect: status: NOERROR
expect: the SOA record to be present in the answer section
expect: an OPT record to be present in the additional section
expect: DO=1 to be present if an RRSIG is in the response
expect: EDNS Version 0 in response
expect: flag: aa to be present

The actual output from dig goeth thus:

dig +nocookie +edns=0 +noad +norec +dnssec soa ietf.org @
jill.ns.cloudflare.com.
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 20613
;; flags: qr aa; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1

;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags: do; udp: 1232



Seeing as the document says you should "expect: flag: aa to be present", it
does seem like it would be better if it also said: "expect: flag: do to be
present if an RRSIG is in the response", as that is more inline with what
someone writing a test would see.

This seems like a fairly simple clarification / place where things could
have been worded better, but I don't think that it rises to the level of a
"Verified" errata, but it's also not wrong, so my proposed resolution is:

Accept the errata as Editorial, Hold for Document Update.

("Hold for Document Update - The erratum is not a necessary update to the
RFC. However, any future update of the document might consider it and
determine whether it merits including in an update." — from:
https://www.ietf.org/about/groups/iesg/statements/processing-errata-ietf-stream/
 )

Can anyone not live with this? Please speak up by Jan 29th, otherwise I'll
do what's above.
