Hi
I reviewed the draft and here are a few comments:
“The PADDING octects MUST be set to 0x00.  If a Responder detects non-
   0x00 octects in the padding of a query, a FORMERR (RCODE=1) MUST be
   returned.”

è Is MUST necessary here? There might be existing responders that may be 
agnostic to this and not parse this option code. They may not return Formerr. 
For quick adoption changing this to SHOULD or providing option to ignore this 
will be useful.

è What is the guidance for the proxy systems used in front of DNS servers (load 
balancer or traffic managers)? Should they be validating this option for 
correctness or be plain tunnels?

è What if the packet does not have space to pad? Do we have a Padding option 
with length 0? Or we truncate messages?

The 'Padding'
   option MUST occur at most once per OPT meta-RR.

è Is not there only one OPT RR per packet? There can be multiple option IDs but 
RR is only one. Just checking if the statement above is semantically correct.

Also, +1 for approval
Thanks

Subject: Re: [dns-privacy] Call for Adoption: draft-mayrhofer-edns0-padding


I've submitted a -00 WG version of the draft, which is now pending WG Chairs 
approval.

Hope I got everything right, since the draft was edited from a phone onboard a 
ferry with crappy wifi and while coloring a pirates book with a 3yo ;-)

During the meeting on Monday, it was obvious the Working Group wanted to
make this an official EDNS option.  We reached out to the author and
while he is traveling for an extended period of time, he is happy to
work on edits (with a small delay built in, but nothing this impatient
chair finds too onerous).
