[DNSOP] Re: Call for Adoption: draft-huque-dnsop-grease
I would welcome adoption of this draft. I think Grease should be a more widely applied concept. I don't personally like how some fields are now marked ring-fenced as "always zero" and while I have to be realistic we can't reverse course on this I think all bitfields which are multivalued with reserved values should be tested to flow with as-yet unassigned values, regularly.

[DNSOP] Re: Side Meeting - DNS Load Balancing
I hold that ietf docs are pretty good at normating behaviour seen to be used. Post fact "this is how it is" seems to work. They're pretty terrible most of the time at ending behaviour not seen to be directly harmful to making money. They're functionally useless at wish fulfilment.

Re: [DNSOP] DNS Grease?
Not in any way to stop this specific draft, I wonder if this is a more general principle of exercising code points which are not marked "never to be used" and should also be raised cross-area, or in another place? Maybe the best path is to get this proved here, and then embrace-extend. I tend not to what-if the downsides, but I can imagine there would be an initially high rate of failure which causes log flows, threat analysis feeds and some consequent damage. That would have to be a "lesson learned" and then we pass through to a better understanding of which bits in a header are mutable and should not be tested as fixed value fields. Nice, small draft. -G On Tue, Feb 27, 2024 at 10:29 AM Shumon Huque wrote: > > Hi folks, > > Mark Andrews and I have submitted a new draft on 'Greasing Protocol Extension > Points in the DNS'. > > https://www.ietf.org/archive/id/draft-huque-dnsop-grease-00.html > > (datatracker link: > https://datatracker.ietf.org/doc/draft-huque-dnsop-grease/ ) > > We'd like to see if there is interest in working on this.

I support publication. The remainder feel like nits which would get resolved in editor queue. I discussed the priming issue with Paul H privately and I think his response covered my concerns. Basically, if you run hyperlocal root, it subsumes the functionality of the cache priming activity, but it doesn't need to be explicit in this document, its a redundency, and adding language to address this is like patching 8806 as a side effect, which we don't need to do: in fact, it has risks.

Re: [DNSOP] NOTIFY: How to locate the target
I think we're conflating how you learn what endpoint to send NOTIFY to, with the protocol extensions or changes to make it legal/normal to do NOTIFY for this purpose. I don't personally think the whole "but how do I know where to do it" is as important as some of you seem to think it is. But, having the definition of this use of NOTIFY wired down for its protocol elements and behaviours, I think thats important. I fully expect the actual endpoint to be OOB. I don't think it has to be in band but I don't mind if there is an RR which handles in-band, but to me that isn't the main point: the main point is knowing its a general expectation I can do this to parent/publisher when I need to, and what protocol it looks like. Maybe I am missing the point. Sure, CDS was all about in-band, but to me, NOTIFY is mechanistically about a HOW not a WHERE. HOW do I format records to make a push event happen. WHERE is between me and my parent. -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
Re: [DNSOP] Fwd: New Version Notification for draft-many-dnsop-dns-isolated-networks-00.txt
I wonder if some kind of "limited licence local signing key" model could be used, to get a signed permit from a "real" TA in the DNS to specify the zone(s) that a limited licence key could use, with a far longer than normal time over the rights signing. Because we don't want inflated lifetimes/validity intervals at large, but you probably need something which can sustain the long delay component here. The absence of repudiation in this model (which was conscious and deliberate as I understand it, rejecting CRLs) means there's no easy mechanism to say "I changed my mind" over long lived things. Long ago, Australia operated a national DNS model which had a 9600 "dns & ntp only, munnari mostly" link behind it, which allowed one node to sync and certify into the root. It wasn't formal, it was self policed, and it pre-dated widescale IP connectivity (from memory, 3 or 4 universities in Melbourne plus the CSIRO had access) -which meant we could get on with using IP in a local context but remain connected to the namespace through a thin long wire. I'm not sure it actually had any advantage over a periodic re-sync from a zone state, other than being 'the IPv4, just a bit constrained' This isn't the only proposal in name to address processes which harks back to HOSTS.TXT, I am sure others have (it may be I have been reading other things in the same space about interplanetary internet) -And maybe the way forward is to focus on the complete zone, and signed states (ZONEMD?) over the complete zone which could establish trust, and not demand new/different TA structures? -G On Mon, Oct 9, 2023 at 5:18 AM Marc Blanchet wrote: > > Hello, > The primary use case of this draft is the deployment of naming > infrastructure on celestial bodies networks, but could be applied for other > use cases. > > Would love to get people reviews and comments. > > Marc. > > Début du message transféré : > > De: internet-dra...@ietf.org > Objet: New Version Notification for > draft-many-dnsop-dns-isolated-networks-00.txt > Date: 8 octobre 2023 à 15:16:10 HAE > À: "Marc Blanchet" > > A new version of Internet-Draft draft-many-dnsop-dns-isolated-networks-00.txt > has been successfully submitted by Marc Blanchet and posted to the > IETF repository. > > Name: draft-many-dnsop-dns-isolated-networks > Revision: 00 > Title:Domain Name System in Mostly Isolated Networks > Date: 2023-10-08 > Group:Individual Submission > Pages:7 > URL: > https://www.ietf.org/archive/id/draft-many-dnsop-dns-isolated-networks-00.txt > Status: > https://datatracker.ietf.org/doc/draft-many-dnsop-dns-isolated-networks/ > HTML: > https://www.ietf.org/archive/id/draft-many-dnsop-dns-isolated-networks-00.html > HTMLized: > https://datatracker.ietf.org/doc/html/draft-many-dnsop-dns-isolated-networks > > > Abstract: > > This document lists operational methods to enable local DNS name > resolving on an isolated network, where that network have > intermittent reachability to Internet and/or have very long delays, > disabling the real-time query and response flow to the authoritative > name servers on Internet. > > > > The IETF Secretariat > > > > ___ > DNSOP mailing list > DNSOP@ietf.org > https://www.ietf.org/mailman/listinfo/dnsop ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
Re: [DNSOP] what could we do with 15 unused bits of QDCOUNT?
I don't agree. My reasoning is that signals in the first 576 bytes are more likely to pass through non-conforming systems based on length alone. There is also John Scudder's observations on fast-path and slow-path processing: if its inside the state you latch EARLY when you see the packet, its far more likely to avoid CPU stalls and get done in firmware or hardware. (probably not strictly applicable, but I go to "flag early, flag often") But, for other reasons raised by other people, I concur that these bits are excluded from use because we don't have time travel and middleboxes make false assumptions. -G On Thu, Jul 27, 2023 at 10:08 AM Robert Edmonds wrote: > > George Michaelson wrote: > > if QDCOUNT is defined as [0|1] then we have 15 new bits of freedom in > > the header. > > > > What would be interesting uses of the flow-label?

Re: [DNSOP] what could we do with 15 unused bits of QDCOUNT?
I like your idea! Another one is to reserve n bits for the length of the resolver/forwarder chain to the answer. if you pass it on, increment the n bits. preserve it in the answer. would permit authorities, and clients to know how long the chain is behind the answers they see and questions made. I posit 3 bits would be plenty. -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

if QDCOUNT is defined as [0|1] then we have 15 new bits of freedom in the header. What would be interesting uses of the flow-label? Oh wait.. that's right, nobody really knows at scale how to use flow-label either. I tend to "use it for 15 bits of signalling" because there are a lot of things I wish were signalled from client to server.

Re: [DNSOP] should all ccTLD be on the Public Suffix list?
so some TLD don't. But also some ccTLD are using notation which probably doesn't matter much, but confuses me because it is wildcarded ONLY where other ccTLD put both the bare TLD and the wildcard (as noted before) look, there's nothing to see here. my confusion is not an industry wide problem. ccTLD aside, ICANN has contract levers with gTLD and if there was reason to tweak the lever they would, and thats not "our" job. my concerns with the PSL governance aren't relevant either.

[DNSOP] should all ccTLD be on the Public Suffix list?
I know, I could submit these to the PSL website directly. I am asking a meta question: do we think that operationally, if a PSL exists, that all ccTLD and TLD should be on it? The following ccTLD are in ISO3166 but not in the PSL: bd bl bq ck eh er fk jm kh mf mm np pg um za all the other ccTLD in iso3166 appear to be on it. As well as the usual non-ISO3166 suffixes like EU and UK. I could have asked this on dns-operations, my wondering here is that maybe we need to suggest to ICANN that it's a formalism? Operationally, much though I dislike the PSL (for entirely subjective reasons I might add,mostly around governance and ancient history) it exists, no matter what I think about it. So, given it exists, systems are coded to behave against it, and not having SOME ccTLD (and I would posit gTLD) on it, means they don't match as "first class citizens" the behaviour the PSL brings. I could also understand a pushback "somebody else's business" or "take it up with ICANN directly there's no IETF in this" as well as "the CCTLD self manage, nobody tells them what to do" (the PSL is discussed from time to time here) cheers -George ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

Re: [DNSOP] [Ext] WGLC rfc8499bis one week extension for lame delegation definition
When people talk about "lame" they're in a sentence with a subject (the DNS), and an object(ive) -But there isn't a single parse. Sorry, but the declarative "this is what it means" seems to me to be failing, hard. The subject(s) are the zone(s) that are lame? thats one case. the other case, is the subject is the NS which is listed as authoritative but isn't serving. OK so you can qualify "lameness" to "the zone is lame" or "the zone has some lame NS" or "this NS is lame for the zone" -But they have different subjects and objects. what is "this" in each case? different. And not serving has (at least) two forms: you respond to 53 but reply incoherently if at all about the zone, and you aren't even responsive on 53. I can believe there are more. The objective is to fix it. You are either talking to the parent zone delegates to get something changed in the parent zone, or to the zone NS admin to get something changed at the NS, or to network technicians about why something along the path isn't working for you. So thats 3 cases at least. Yet, we all seem to call this "lame" for some purposes. At least 2x who talked to, at least 2x forms, and at least 2x subjects but one Objective: -- fix it. I don't think we've cohered on a meaning. I respect Paul Vixies intent in giving clear origination of the term to Mark, but I do not agree the term means now what he said decades ago, its clear we don't (in this mail thread) really have a unitary meaning. If we did we wouldn't be here. I don't see how a single paragraph statement without OR ... alternates is going to cover what people patently have been saying "is lame" for some time, not aligning to a single meaning. I liked the proposed paragraph because it had the ".. or not at all" -And yet some people seem determined to say thats the "wrong" bit on the definition. ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

Re: [DNSOP] WGLC rfc8499bis one week extension for lame delegation definition
I prefer option 2. I think it fulfills the implicit obligations inherent in 1) -which would be to fill the hole of uncertainty. Its succinct, and it covers the cases I think define the condition. I would ask if 2) also needs to define ".. or cannot be resolved" because "[or not at all]" is a bit wide to encompass "that FQDN didn't actually resolve" for a listed NS. As it stands it seems to terminate in a belief you have something to ask. It's equally lame to be pointed to this.name.hasnt.been.delegated.alt. as an NS Irrespective I prefer 2). I don't like the dangling fate of 1) I think the lack of agreement is only conditionally true: I think we could reach consensus on 2) if we tried a bit harder. -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
Re: [DNSOP] WGLC for draft-ietf-dnsop-zoneversion
I've read this draft. I think its a simple and straightforward proposal. It explicitly notes the security issue that its not covered by DNSSEC, it has implementations, and it had a good discussion run 2021/2022 which was overwhelmingly positive. I had no problems understanding the intent. its really clear and straightforward. It's a debug tool. It isn't going to be something I expect to use, but I like the idea if something goes awry in the responses I am seeing I can ask the authority to tell me what SOA serial I should expect to see, that has the response state they're giving me for the specific query. Thats distinct from ZONEMD which is a DNSSEC signed state of an entire zone (assuming it can be done) which is a different class of check on zone state related to serial. I like both. They're different. That said, you COULD point to ZONEMD in this one in the security considerations, but I wouldnt make it normative. It's just another way to check the state of a zone. The non-transitive thing is about the only point of "well" -but its unsigned data: how could you trust it, if you can't verify through a third (transiting) party? And the draft says this: it's undefined behaviour. I truly think this is that very rare bird: "looks good to me ship it" in 2 WG adopted draft edits.

Re: [DNSOP] Meaning of lame delegation
The shortest path out is to avoid use of the term and be explicit about the 3 (false trichotomy: there may be more) cases. If they lack labels, then number the bullet points or paragraphs and refer to them as RSSAC-.A.B.[C|D|E] instances until the name(s) settle. We're unlikely to terminate in a definition quickly.

Re: [DNSOP] New draft: Compact Lies/Denial of Existence in DNSSEC
My opposition is philosophical and practical. the philosophical part, is that this is a SIGNED ASSERTION by the zone authority. I don't think anything the zone authority says under a signature should be called a lie, because the basis of verification is that its exactly what was intended to be said about the state of the zone. its incoherent, its potentially confusing, it needs to be understood, sure. but I don't see this as a lie. the practical is that I think the IETF/OPS tendency to enjoy "puns" causes huge confusion outside the cognoscenti. The re-use of the word "peer" for instance has caused significant dismay to people in policy or finance space who don't understand that a BGP peer does not mean necessarily a peering zero-cost sum arrangement at layer 8 and 9 (money). -If we use "lie" this freely, then when we want to distinguish these signed lies from the intermediary altering payload on-the-fly we're going to have a problem of comprehension. Having said that, I think I feel like a bit of a party pooper. What in Australia would be called a "wowser" It's not a big deal btw. I'm not going to go to the AD and complain about it or make a fuss at WGLC.

Re: [DNSOP] QDCOUNT > 1 (a modest proposal)
purely administratively, I'd like to understand how the WG chairs and AD intend dealing with fundamentally opposed drafts. I would think that a formalism here might be needed: if we discuss A and not B and reject A, have we implicitly accepted B? And vice-versa? Do we actually need to discuss both together, most of the time, to come to understanding about this? I'd suggest the existence of oppositional drafts (by intent, in no sense do I see this as personal) -the WG adoption question is moot: we probably need to adopt a problem statement if not the two specifics. Is there room to unify?

I got quite used to being told "stop inventing things" and as a general principle, its not such a bad thing to be told. But it occurs to me, inventing a way to be told authoritatively where the zone cut should be might not be such a bad idea, if it was useful. If the alternative is to have to look for it, thats just a cost, I admit. But the question would stand: if we had a way to tell the delegate where the zone cut was above them, would it be useful?

Re: [DNSOP] Anything goes in ALT, was On ALT-TLD, GNS, and namespaces...
You appear to be taking the concept to a place where alt is the label which defines the start of non-DNS switching, and the 2LD is the specification of the namespace/service you work in. So its a domain model, driving to software and namespace path, before it begins resolution of the name proper. (presumably, the remaining F.Q in the FQDN if DN is now .alt So where I was asking "why aren't we talking about mechanisms to do this in omnibar and local control file like nsswitch,conf" you're saying "given these alternate mechanisms exist, how can we assert a global name which can identify itself as being addressed to a specific mechanism for name lookup" In hypothesis, in this model, ALL FQDN we have "now" are in fact FQDN.dns.alt ? The dns.alt being assumed, and not necessary in the default DNS case? I ask, because NOT grandfathering in the current name scheme into a new name scheme (as a child/grandchild) invites problems. If the dns.ALT name is "reserved" then, there can be no confusion in the mechanisms which do ALT service parsing. Basically, "if you do .alt, and if the 2lD under alt become a registry of namespaces/services then you MUST reserve dns.ALT" -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

Re: [DNSOP] On ALT-TLD, GNS, and namespaces...
How to privatise the commons in names. 1) release a browser with remotely enable-able features, initially disabled 2) when you hit 95% penetration, enable the feature. If the omnibar in the dominant browser had a selection logic akin to nsswitch.conf or resolver.conf config options, this debate moves from a tech governance space to a vendor decision in 3-6 months. At which point, the additional TA and equivalence to the public suffix list is strong. We're lucky we don't seem to have a vendor who wants to try it, because logistically it would be extremely simple. My point is that gethostbyname() itself is subject to code if/then/else decisions, so the idea names are gated by protocol or functional API spec is really moot. It's a soft agreement only. My own hosts (laptops) still appear to honour /etc/hosts before DNS. I used this in China for gfc reasons. So local override is also strong in this.

Re: [DNSOP] [EXT] Re: draft-schanzen-gns and draft-ietf-dns-alt-tld
Not trying to say you're wrong, I just observe that if there is an omnibar, and people type names into it, then there is a latent problem of ordering lookup, and deciding, in names and more than one namespace. Pretty much all the hard stuff stems from there IMO. Names are hard. I think belief in the value of a unitary namespace as a commons probably always transcended the DNS specifically. We're just in denial what "it" is that we're fighting to defend. DNSSEC made this perhaps more focally clear: the specific value here is (in my opinion) in "which TA do you respect" and how that goes to "which name do you believe" which in this case goes to "which namespace do you prefer, deciding which names to accept" The unitary namespace belief, goes pretty rapidly to "how many distinct, independently managed TA do you want to respect proving names" as a cross product with "when, in which order, and why, and what do you do if they collide or disagree" If GNS is glued into DNS as a sub-arc over a label we understand, the possibility of some unity, fusion of purpose exists. If it squats, or is pushed aside, then that possibility disappears. To me, thats the problem. Not that we're finding this is ugly, or we like or dislike a reserved label like this, or want to never invoke the method we documented to do this thing, or hate ICANN or a hundred other things: its the loss of fusion of behaviour, if we don't come to some sense of agreement in what names are, respecting locators (and addresses) -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
Re: [DNSOP] [EXT] Re: draft-schanzen-gns and draft-ietf-dns-alt-tld
In a similar spirit to avoiding "be damned" in a doc, I think referring to choice 3 as "squatting" is probably both truthful/accurate, and regrettable. We probably shouldn't formally document (ab)use of a space this way without more considered language and text around what it implies. I thought your notes were helpful, a good write up of the "pick the least worst" choices we've arrived at. I increasingly tend to think if somebody in a public interest space had the $ and invested the cost of delegating via ICANN process and handed it over for this purpose to a registry, it would avoid all the pain of trying to document a special-use: Simply get the delegation, burn the $200,000, meet the ongoing opex, and turn it into the space through external process compliance. Basically, the IETF has two problems: it's trying to invoke its rights to request a (non)delegation against its better wishes, and it can't entirely agree (achieve consensus?) inside itself on the wisdom of doing it. Getting it through an external application outside of IETF decision logic and then bringing it into the IETF might be easier, if not cheaper. -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

It just couldn't come to a single point of view. A lot of the issues are layer-8/9 and I think it's most likely this is a sign of a problem which demands a different kind of document, not an ISE document.

Re: [DNSOP] CDS Bootstrapping for vanity DNS servers
As a point of information, All the parent zones (the /8 and /12 RIR delegations in in-addr.arpa and ip6.arpa) are now signed. Or should be. it is possible a couple of stand-out /8 holdings aren't but thats resolvable at some pain. The problem would be that for CDN hosting instances of DNS, the uplift of the credentials for a specific NS instance "inside" any given sub-delegation demands that parent space itself be signed, and that they offer some mechanism to allow NS instances to associate their info with the record. Its the classic "how do I make sure my registrar follows spec and supports this" but instead of being about gTLD and ccTLD its moved into the un-regulated in-addr and ip6 .arpa subspaces, where the registrar in question is an address delegate. Outside of the people who already have mechanisms to do things (the gTLD and ccTLD and the big players and historically vested ISPs and tier-1s) I hazard that few DNS lie in self managed integral address ranges, and most DNS lies in managed, rented, sub-allocated address space. -George On Wed, Jun 22, 2022 at 1:29 PM wrote: > > > > On 22 Jun 2022, at 00:07, John Levine wrote: > > It appears that said: > > -=-=-=-=-=- > > > Hi. > > During a meeting today of ROW (https://regiops.net), the I-D on CDS > bootstrapping by using a DNSSEC-signed name at name server > zone > (https://datatracker.ietf.org/doc/draft-ietf-dnsop-dnssec-bootstrapping/) was > discussed. > In that discussion, it was mentioned that the current draft only supports > out-of-bailiwick name servers; I replied that the > same principle could be applied to in-bailiwick name server by usage of the > reverse DNS zones for IPv4 and IPv6. > > > Urrgh.

Re: [DNSOP] Another attempt at consensus on the bailiwick discussion
This is one of those times where classic email quoting isn't helping my brain. Maybe I'm alone, but I think there may be others in a similar situation. We're close to a discussion of very specific language. I think the best thing is for people to state once, in their level of indentation (ie "top") *EXACTLY* what specific language they think we need here. Say the text. All of it (that you want to discuss) as you want it to be in the document.

Sorry, but I think this is just an over-reach. There is no necessary reason for a single information model to break. It is about how you do it. The problem of course is transitive links in the tree from one state (signed) to the other (unsigned) and back again, and associated meta data. Arguably, its one information model, one cache, but the DO bit flagging limits what answers you can tell people and you have to reply with SERVFAIL for information you hold, even though you know the next query might well be for the same info without DO force. It may well be logistically simpler to run two caches, but this statement seems to me to be over-stating things. G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
Re: [DNSOP] I-D Action: draft-ietf-dnsop-glue-is-not-optional-02.txt
I had it said to me, that "lies" about the ns.bar.example are not a problem because if they can tell you a DNSSEC verified truth about the primary request, you don't care who told you. That can only be truly not a concern, if the primary is DNSSEC verified. So, for the non-DNSSEC, it feels like a substantial problem. But then.. the only way out is to BE DNSSEC aware. There's not much choice. I'm not convinced this "glue doesn't have to be validated" thing is true, but the problem latent in this is the recursive time/compute cost of chasing all out-of-baliwick data, to verify its status in DNSSEC. Love to hear other people's POV on this. Maybe it is a false meme on my part? Maybe glue HAS to be checked and validated, no matter what? -G On Wed, Jul 28, 2021 at 2:16 PM John Levine wrote: > > It appears that Paul Wouters said: > >On Tue, 27 Jul 2021, John R Levine wrote: > > > >> Well, OK.

Re: [DNSOP] [Ext] Starting a -bis document for RFC 8109: Initializing a DNS Resolver with Priming Queries
No. thats good and clear. Priming is not just the concept of being correct, its specifically following a mandated in-band mechanism. It is a standard, and the bis requirements are not just "arrive at the state, don't care how" they are "arrive at the state by following this specific procedure" -otherwise, you cannot say you are primed in the RFC sense. -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
Re: [DNSOP] [Ext] Starting a -bis document for RFC 8109: Initializing a DNS Resolver with Priming Queries
If I (insanely) ran a totally manual, out of band process to periodically canvas the space and injected the knowns into the model of "root" for my resolver, would I be able to say I am primed? I am trying to get to the point that the "how" part is only exemplary, explanatory. The requirement is that you have the information, now how you get it or how it comes into your resolver. The distinction between shipped states of the root.hints and the actual live mappings of the domain labels inherent in it, to addresses (if you like) I can bypass the hints file ,and use SQL to update my root mapping. I think the intent of "priming" is that you then populate the information from 'inside' DNS. But, again, its only advisory, its not standards enforced is it? I can populate my continuing knowledge of the state of the DNS at the root, or anywhere else, in any mechanism I like. I could periodically FTP the zone files from places, and populate my resolver cache state from these. I could basically "never" forward DNS queries high in the tree, if I felt like making my server do that. Am I "not primed" if I do this? (this mechanism wouldn't support authenticated denial of arbitrary labels, as an example) -G On Fri, Aug 7, 2020 at 12:42 AM Paul Hoffman wrote: > > On Aug 6, 2020, at 4:08 AM, Andrew McConachie wrote: > > > > What does it mean for a resolver to be primed, or for a resolver to not be > > primed?

You make a useful important point here: an "open resolver" is the superset of "deliberate" and "abused" ones. The concept here is that the intent is deliberate, we need some way to say so. if the intent is not there and is being abused we need some way to say so. I started typing this as "good" and "bad" but we know not everyone believes open public resolver services deliberately deployed ARE a public good, all the time. So I went to deliberate and abused, because there is "I do this by intent" and "it is being done by accident" -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

My Colleague George Kuo asked me for definitions of public DNS service. not "public DNS" but the trigram "public DNS service" Colloquially we understand this reasonably well. It is in the space of what Google, quad9, CloudFlare and others do. The various clean DNS feeds people subscribe to, it is the functional role of a recursive, but to the public, yet somehow not the bad one of an open DNS resolver being abused to do DDoS: its the conscious service offering of a recursive/cache/forwarder in the public view, a declared intent. A Google search lists (some of) them by name and IP. I asked "Dr Johnson" (Paul Hoffman) why it was not in his dictionary, and he said he is but the humble scribe, and words appear in the dictionary when he is directed. What does the WG feel?

I support adoption. I wondered a little about "it is absolutely essential for these transfers to be protected from unexpected modifications on the route. So, catalog zone transfers SHOULD be authenticated using TSIG [RFC2845]." The use of a categorical *absolutely* and SHOULD is jarring. If this is really categorical, the normative enforcement needs to be stronger maybe? I also wondered why the TTL of the RR is not held to be meaningful. It felt like there is an opportunity to use this field but thats quibble, the document as-is defines it as 0 and thats ok, if perhaps missing an opportunity to use a field close to the zone being catalogued for some purpose.

This is a not uncommon problem in 'make this protocol work in future' spec. It could say "for version ZERO of this protocol" and then say "future versions of this protocol should stipulate what other values mean, and how this affects handling of all-zeros state, and other states" Saying "must not validate" baldly basically says "will always be zero" to me -Which I think is what you're saying! _G On Mon, Sep 9, 2019 at 3:04 PM Shane Kerr wrote: > Duane, > > On 2019-09-06 02:01, Wessels, Duane wrote: > > > > With this version the authors feel that it is ready for working group > last call. > > Sorry for a late comment, but I decided to give this one thorough last > read-through. > > I'm a little concerned that the way the Reserved field is described may > make adoption of later versions of ZONEMD difficult.

Re: [DNSOP] I-D Action: draft-hoffman-dns-terminology-ter-01.txt
I dislike the rate of change in terminology, and what feels like intrusion of somebodys favourite term, which is not actually reflective of widespread use in DNS discussion. I have never said DO53 and I don't know anyone who has. Every other term of art, has sound basis. This feels like a bad backronym and we are now moving from a terminology to an emerging AI aware ontology of phoneme-building. Can we stick to acronyms which really exist? Is this in a document of substance and I missed something? (very possible) A dictionary model I like (btw) is to show the earliest published use of the form, to set its context and definitions as they emerge. -G On Thu, Jul 25, 2019 at 10:37 AM Tony Finch wrote: > > Paul Wouters wrote: > > > > I dislike Do53, because then we should really have Do53-over-TCP as DoT > > and Do53-over-https as DoH.

But having said that, I think the lack of capabilities signalling in DNS, compared to say SMTP or HTTP is a huge problem, and since we have it in those protocols, I feel we have a basis to suggest there is not a blanket ban on this kind of thing in the model. Because of the massive lack of information about elements of the system, the lack of signalling is actually causing a problem.

Support adoption. This is a mechanism which I think is useful and which permits out-of-dns provisioning mechanisms to have high trust in the specific state of a zone being fetched.

Re: [DNSOP] Informal meeting about root KSK futures at IETF 103
I feel backup key, and alg, are sufficiently of wide benefit, that the qualms about frequency are second-order to the primary goal of an improved outcome 1) backups go to stability of unplanned events 2) new alg would permit a return to shorter packet sizes even across keyroll, which makes IPv6 DNS on UDP more reliable I understand your concern, but I think its cart-before-horse stuff. We *want* shorter crypto sigs. and we *want* more reliable behaviour in unexpected circumstances. We can't get there, without another keyroll. probably two more. -G On Wed, Oct 31, 2018 at 9:40 AM Mark Andrews wrote: > > Name server vendors have NO CONTROL over when down streams pick up changes. > We would like OS vendors to pick up maintenance release sooner than they do. > It would reduce the amount of time we spend diagnosing already fixed issues. > We spend the time back porting fixes so people can have stable interfaces > and fixed code.

Re: [DNSOP] Informal meeting about root KSK futures at IETF 103
There is a tension between assumed privacy ("this is my resolver, what
I run is my business, how I run it is my business") of entities
running resolvers, and customers ("this is my DNS query. what I ask is
my business") and providers of infrastructure ("this is my liability:
the consequences of not understanding what we are doing expose me to
high consequence risk")
Some significant players in DNS conversations have been remarkably
oppositional to instrumenting the protocol.
I think on balance the question "can your resolver survive the KSK
roll" is not a massive invasion of privacy, is not a huge impost on
providers of DNS service, does not interfere with implied rights to
privacy. We should have better knowledge. We should instrument the
resolver. The protocol. We should not be forced to do ludicrous things
to find this out, it should be as innate as the telnet capability
negotiation, or the HTTP client/server capability negotiation. We know
how to do these things.
I am statist. I do not pretend states don't exist. I am not a
libertarian, I am not trumpeting DNS as a tool for individual liberty.
DNS is a useful functional element which now has consequence when it
doesn't operate correctly.
We've walked a long way into an industry self-regulation outcome which
I feel is as consequential as 250v or 50hz, both of which are defined
parameters with variances and tolerances which people in the
electricty supply industry have to respect, to remain protected by
public liability insurance. We should consider the public DNS in the
same light: If we want to avoid opprobrium over mis-steps in operating
the root of the DNS, we should adopt a rational posture akin to the
ones in Power, Water, Sewerage, because thats what we are: a public
utility function. With public utility liability questions.
Rightly or wrongly DNS is a critical service, which has potential for
wide impact which is not good. It didn't (this time) at scale, in as
much as nobody has come forward to say it did: The assumption there
has been *no* damage, or *no* loss of service feels to me wrong. I am
(as a gambling man) confident it was low, in as much as 2.3b users
didn't rise up and grab pitchforks. I bet it was big enough (remember,
0.001 of 2.3b is 23,000) that you'd fill an auditorium.
Is 1 in 1000 an acceptable damage rate? is 99.999% unaffected ok? Why
is 98% not ok? or 97%? Where IS the acceptable damage boundary? Who
gets to say what will be tolerated as loss in the DNS system, for what
period of time?
If we want to "plan" for rolls, I think we should stop allowing "not
on my server" to impede DNS protocol design which would provide
un-ambiguous signal of capability in the field. And "not in my
protocol" too. If you offer a service like 8.8.8.8 or 9.9.9.9 or
1.1.1.1 you should be in a position of community obligation to be
completely clear what your posture is towards KSK roll, algorithm
roll. If you can't support it, you should say so. If that means people
are advised to TURN YOU OFF that needs to be understood.
If we want to perform algorithm roll, get stand-by keys, we should be
prepared to argue for the changes which make it easier to do these
things.

Re: [DNSOP] Clarification question: compression pointers always to names earlier in the packet?
As long as we're in UDP, with DNSSEC, and many NS, packetsize in DNS will be a "thing" and revoking label compression pushes to fragments and/or TCP. Personally, I think TCP is fine, and the emergence of long-lived bindings in DNS is fine, and this is a bit overblown as a problem. But, I get reminded by people just how long, deep and *old* the CPE embedded DNS footprint is. Which believes UDP at 512 is a "thing" So basically, yes: you can turn it off. But.

With IANA registry requests, I may be wrong here, but I thought we had some (boilerplate?) language about how IANA is asked to operate the registry: what criteria judge acceptance.

I have said before, but don't know if I still adhere to it, but anyways, here's a question: How *long* do people think a biassing mechanism like HE is a good idea? * is it a good idea *forever* * or is it a transition path mechanism which has an end-of-life? * how do we know, when its at end-of-life? I used to love HE. I now have a sense, I'm more neutral.

Re: [DNSOP] Global DNS architecture changes, "the camel", and so on
I sort of agree. The addressing, a naming function and routing are the three legs. If you do naming right, you can drop addressing and use ephemeral addresses, and if you do routing right you can drop addresses and do ad-hoc. But you need addresses and routing if you want to do without names, so I kind of see this as a triumverate we're grown into now (obviously there are other legs, like security, which we always cut away in launch and then miss. three legged stools are not stable...) But that said, I see this other dimension. we don't run r* commands any more. We don't run UUCP any more. Things which feel baked in turn out to be ephemeral to the core function. So name functions? Up where Brian Trammell is writing drafts? Sure. we need that. What underlying protocol it maps to, Thats a big statement. I don't buy that forever more amen it maps to UDP. If somebody makes DOI work over ICMPv6, I could believe in 25 years we'd migrate to bootstrap of DOI via ICMPv6 and be out of the DNS moment entirely. As it stands, almost all bootstrapp-y application phases accept address literals sorry [address:literals] somehow. Names are only a convenience function, set against routing. ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
Re: [DNSOP] Global DNS architecture changes, "the camel", and so on
I am less sure the UDP/TCP thing reduces to "no" I see no reason any more to assume session cost is too high for a globally deployed DNS. I suspect what DNSOPS and a hypothetical directorate thinks about DNS is less impactful (sorry, hate that word) than what embeds in Android devices. de-facto, the world runs on session mediated services. BGP has a session. QUIC is a session with IP address agility. DNS over HTTthing is a session. So there is no necessary end to simple UDP dns, but I suspect over time, most "edge" DNS queries by volume and device, will move to another protocol layer. In email, we used to behave like SMTP was all there was (the ironies, given how many sendmail configs drove DECnet or UUCP or ACSnet or BITNET mail..) We now recognise MTA, MUA, MDA and we live with SMTP/TLS IMAP and POP. Oh, and gmail...

Re: [DNSOP] Incremental zone hash - XHASH
The intent (to me at least) is to be able to use exterior fetch, *not* DNS, to source this as a file. curl. wget. ncftp. rsync. the "thing" is a file object. It almost certainly is in near-canonical sort order already. Its a stream of characters, probably in bind-normal form. If you can compute the path through the labels and the chain of NSEC regions and the expected hadda-yadda-dadda.. you don't *need* a digest. If you have a digest, and its already in near canonical order, then *cost* to compute "is the file exactly as the publisher wrote it" is low. And, since its a signature under the ZSK, its not just "its as the publisher said" its "the publisher knows the ZSK" which is strong enough to say: "just load it" So, I ask: is this incremental method applicable to this model? Sure, works for giant zone. What about a root zone? Do I need this?

Re: [DNSOP] New Version Notification for draft-wessels-dns-zone-digest-01.txt
What I want is the nexus of OOB "file" form zone download and integrity check which is cheap to implement signer and receiver. I was on PGP. Duane has taken me to an RR which is a sequenced, canonicalized digest, which then is under the ZSK sign of the zone. For the root, it feels doable. For Com, nothing but a cipher-block-chain model of intermediates is going to scale but a single file download and integrity check was always going to fail there. I know you're talking in-band download: I am targetting out of band "file" download. Its a model. It works. Its useful. The least dependencies and easiest path is what I seek, Olafur drove to a new keying regime and external signatures.

Re: [DNSOP] New Version Notification for draft-wessels-dns-zone-digest-01.txt
Yea, having read things properly and been hit by a cluestick I think this is good. * the RR is a digest over canonicalized state * there is a simple method to take zone, re-canonicalize (its the DNSSEC order) and check the digest * since the RR is covered by the ZSK signing, the entire zone is understood to be in the state the publisher had when they made the digest. * if you download a zone file, with this RR, you can re-canonicalize and check easily. You have to have a DNSSEC ta over the keys used come what may, but this looks like a mechanism which given an out of band TA has no in-band DNS dependency to get a zone and check a zone. So functionally, Duanes thing is identical in outcome to PGP signing or other exterior file signatures. -G On Tue, Jul 10, 2018 at 10:05 AM, Wessels, Duane wrote: > George, > > >> On Jul 9, 2018, at 4:36 PM, George Michaelson wrote: >> >> There's arguments both sides about cross signing, counter signing and >> independent self-signing.

Re: [DNSOP] New Version Notification for draft-wessels-dns-zone-digest-01.txt
There's arguments both sides about cross signing, counter signing and independent self-signing. If you want to promote out of band zone exchange, it has to be signed. The key it signs with is immaterial if you either direct knowledge of the PK in a PKI, or accept a trust anchor relationship over it, or a web of trust. So do you prefer (for instance) that the ZSK be used outside of DNSSEC to sign a detached signature over the file, irrespective or content order, if the file is to be made available? Because if you basically prefer its *not signed* for this mode of transfer, you've stepped outside the model: you now demand the file is checked on load, element by element, against the TA, rather than being integrity checked by a MAC signed by the issuer, which permits eg direct binary loadable, or other states. -G On Tue, Jul 10, 2018 at 7:47 AM, Wessels, Duane wrote: > >> On Jul 8, 2018, at 6:02 PM, George Michaelson wrote: >> >> So how about use of a PGP key which is a payload in TXT signed over by >> the ZSK/KSK so the trust paths bind together? >> >> fetch one DNS record +sigs, check against the TA (which has to be a >> given) and then.. > > Currently in the zone digest draft DNSSEC is not mandatory.

Re: [DNSOP] New Version Notification for draft-wessels-dns-zone-digest-01.txt
So if I look at what you said, what I see is "inband, canonicalization is a cost we don't want to bear, to produce a signed product of whole of zone" and "if we accept knowledge of a PGP or other external key as the moment of trust, out of band, disordered but specifically testable as *this file* is signed by *known key* is workable. wow. Firstly, I thought canonicalization was a given: we have definitions of canonical zone order for other reasons (NSEC*) don't we? secondly, I absolutely (and no sarcasm implied or intended, I really mean it) applaud the pragmatism. If we can move to a world which accepts the root is a resource which can routinely be fetched out of band, validated out of band, and then locally bound to a DNS server, we've probably moved on. in-band is great. but, sometimes, its really hard. So how about use of a PGP key which is a payload in TXT signed over by the ZSK/KSK so the trust paths bind together? fetch one DNS record +sigs, check against the TA (which has to be a given) and then.. -G On Mon, Jul 9, 2018 at 10:28 AM, Olafur Gudmundsson wrote: > > > On Jun 22, 2018, at 6:58 AM, Petr Špaček wrote: > > On 21.6.2018 22:31, Hugo Salgado-Hernández wrote: > > On 22:09 21/06, Shane Kerr wrote: > > Dne 1.6.2018 v 12:51 Shane Kerr napsal(a): > > Hmm, can you share some details about your experience? > Did you find out when the data corruption took place? > a) network transfer > b) implementation bugs (e.g. incorrectly received IXFR) > c) on disk > d) some other option? > > > I don't know.

So what is the 'resolver side' of a 'security aware' nameserver in 3.2, 3.2.1, 3.2.2, 3.2.3 and 4? You're not an idiot.

Re: [DNSOP] Terminology: validating resolver
RFC4035 section 3.2 looks like it has usable words surely? not from those words, but in my personal opinion, Any resolver which is able to understand and apply the semantic context of DNSSEC signatures over RR should be considered a validating resolver. However, a validating resolver may also be seen NOT to perform validation because it receives queries with the CD bit set. Therefore, you cannot say that all queries through a validating resolver necessarily demonstrate it is capable of validating. Its not entirely subject to external views of its behaviour without the full context of what was in the query received. -G On Mon, Apr 2, 2018 at 11:45 PM, Paul Hoffman wrote: > Some folks didn't feel all that great about this because it's not defined in > an RFC.

Re: [DNSOP] Definition of "trust anchor"
This doesn't seem a good fit for the PKI definition of a TA. You can have several TA. any are sufficient to define a trust point to anchor validation. you don't care which. how the path is built, is not the same as where it terminates. top down or bottom up is legal in PKI. -G On Sun, Mar 25, 2018 at 8:21 PM, Paul Hoffman wrote: > The current text is: > > "A configured DNSKEY RR or DS RR hash of a DNSKEY RR.

Re: [DNSOP] Terminology question: split DNS
The quality to me, which was there in abstract, is a port-53 bound daemon, which uses the client IP network or /32 to specify how it answers. Server, Resolver, these are distinct classes. I felt split-horizon was the moment of decision logic from "who asked" If anyone has actually bound it to "which interface did I get the question on" thats subtly different, and more side-like. -G On Mon, Mar 19, 2018 at 6:33 PM, Paul Vixie wrote: > > > Ted Lemon wrote: >> >> On Mar 19, 2018, at 6:10 PM, George Michaelson > <mailto:g...@algebras.org>> wrote: >>> >>> "A DNS resolver which looks at the client requesting address, and uses >> >> >> That's a different thing.

Re: [DNSOP] Terminology question: split DNS
"A DNS resolver which looks at the client requesting address, and uses this to serve different versions of information about a zone based on which client address or prefix requests it." the concept of "side" is rather limited. split DNS can encompass more than two sides can't it? -George On Mon, Mar 19, 2018 at 5:47 PM, Paul Hoffman wrote: > Some folks had reservations about the current definition of "split DNS": >"Where a corporate network serves up partly or completely different DNS > inside and outside >its firewall.

Re: [DNSOP] Call for Adoption: draft-huston-kskroll-sentinel
I support adoption of this work. Its a sensible, simple proposal which has immediate benefit, and can be used by anyone to test the ability of their nominated resolver to recognise specific keys, and their trust state. I believe as a community, at large, we need code deployed into the resolvers in the wild, and we need a document specifying the behaviour we need deployed into those resolvers. We can use this to inform ourselves of operational risk under keychange. We can know as individuals, as organizations what we will see, if keys change. I think this is quite powerful. compared to measurement of what resolvers see, or what authoritatives or roots see, going back to these service-providers themselves. This method informs the client side of the transaction. Thats big. I'm not saying we shouldn't do other things, or measure.

Stephane, I don't entirely understand your response. old systems can never understand new code point assignments, or know what to do with it, no proposed change can alter this. Middleboxes dropping unexpected things will hit almost any proposed modification of packets in flight. Basically, I don't think any proposed modification of DNS in this space can be done, which doesn't face this risk: therefore, I don't see it having directing force. If there is some trick to doing something which doesn't expose the risk, What is it? cheers -George On Tue, Nov 14, 2017 at 9:30 AM, Stephane Bortzmeyer wrote: > On Mon, Nov 13, 2017 at 08:54:16PM +0800, > Ray Bellis wrote > a message of 29 lines which said: > >> Would it be feasible to reserve a standard RCODE value in the header >> that just means "see extended error"? > > First reaction: no.

Re: [DNSOP] Remarks about draft-wkumari-dnsop-internal-00
It's not sensible to presume the action of an independent decision-making body. It's sensible to discuss it, but it should only inform our own process logic, not decide it categorically (I think) I might share your expectation of the outcome, but I would hesitate to reject a draft on a supposition. -George ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

Re: [DNSOP] Status of "let localhost be localhost"?
A possibly stupid random thought: is there a strong barrier in *all* kernels which enforces 127.0.0.0/8 and ::1 to actually *have* to be local? The 240/4 problem is 5-6 lines of code in *some* UNIX. It wasn't in any sense globally applied. I suspect localhost is somewhat more strongly coded, but I did wonder because Ted's suggestion that use of the literal IP address in either family would the stronger 'keep it local' made me think: what if somebody hand installed a route which somehow took it off-box? I think proscriptive/definitive language over the FQDN/label localhost in DNSSEC is probably still a good thing. IETF is defining behaviours for home.arpa in HOMENET which logistically fall into a very similar bucket (for me at least) so its not like we can't chose to say what behaviours we expect of a label. -G ___ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop

read, support adoption. suggest that favourite band sections be marked 'RFC-ED REMOVE' because the last time somebody thanked their mother, the backing band, their agent, the producers, the other candidates for award... it wound up on the ietf list and we don't want to go there.

Re: [DNSOP] The DNSSEC club and surprises (was Re: New draft: Algorithm Negotiation in DNSSEC)
A fine bit of epistemology lies in the question: is it the same certificate, if you re-issue it with the same keys? No, because it has a different serial. but the crypto doesn't care, its the validation which cares which is a product of the crypto. so validation cares but cryptographic functions themselves, not such. The nice thing about bare key cryptography, is that fish don't need bicycles. Dates are dates and validity intervals are a thing, but you can re-bake as many times as you like if there is nothing embedded in the structure like a serial. Oh wait.. we sign the SOA don't we... I (for one) hang onto the .req file. Maybe thats naughty, but I do, so in my case Warren routine is that the keypair is being reused, because.. well.. because I like to. Software I consume I suspect (like you) doesn't, and re-mints shiny new keys now with added keynomium, but when I do it by hand? yes I reuse the .req file. But I am probably being led into bad places as a result. I am sure wiser heads will say.

[DNSOP] EDNS0 clientID is a wider-internet question
I probably will not carry the WG with me on this, but I find myself thinking the PII aspect of client-ID makes it a wider-internet question and we might have views as a WG, and promote questions as a WG, but I think the "final call" on this is something which needs more than WG approval. Its a big question. I'd actually welcome adoption on many levels, but that isn't to pre-empt that it goes to WGLC. I think we need to formalize the issues and take them out of the WG for review and discussion. documenting current practice is ok btw, but ..

Read, support. This is a useful addition to document how to do something. Now, the 'outer' question of the value of reverse-DNS label binding, thats a different conversation. I can well imagine a bunch of bikeshed-painting, but lets focus on this as a technique for specifying programmatic population of a zone? I like it. So yea. I think we should have this.
