+Packet number protection is applied after packet protection is applied (see
+{{aead}}).  The ciphertext of the packet is sampled and used as input to an
+encryption algorithm.  For packets with a long header, the ciphertext starting
+immediately after the packet number is used (that is, octet 17 onwards).  For
+packets with a short header, the packet number length is not known, so it is
+assumed to be its largest possible length (4 octets).  Thus, for a short header,
+the sampled ciphertext starts at either octet 5 when the connection ID is
+omitted, or octet 13 when the connection is present.
+
+The protected packet might not have produced enough input for the negotiated
+packet protection algorithm.  This might happen if a packet with a short header
+contains minimal data and uses a packet number encoding that is shorter than 4
+octets.  Additional zero octets are added to the end of the sequence to reach
+the required amount of data.

I was about to propose something similar to @huitema but then thought zero padding might do just as well.

However, I think it is better to take the tail content when the default start overreach because then you can always consume the content directly without moving it to a separate buffer. It's a quite simple solution.

+endpoint validates a remote address by sending a PATH_CHALLENGE frame containing
+a payload that is hard to guess.  This frame MUST be sent in a packet that is
+sent to the new address.  Once a PATH_RESPONSE frame containing the same payload
+is received, the address is considered to be valid.  The PATH_RESPONSE frame can
+use any path on its return.
+
+An endpoint MAY send multiple PATH_CHALLENGE frames to handle packet loss or to
+make additional measurements on a new network path.
+
+An endpoint MUST use fresh random data in every PATH_CHALLENGE frame so that it
+can associate the peer's response with the causative PATH_CHALLENGE.  Using
+fresh values allows the endpoint to measure the time taken to respond to a
+challenge.

This gets a bit weird if the PATH_RESPONSE doesn't come back via the new path.

I would change this to "cannot" from "does not want to" as Mike suggested.

 the

Possible simplification of these three paragraphs:

Assuming all AEAD functions used are reducible to PRFs, an (encoded) pac= ket number p is encrypted as:

    p XOR PRF(pn_key, m),

where m is an L-bit string sampled from a protected packet=E2=80=99s cip= hertext. This construction is secure
against chosen plaintext attacks (IND-CPA) if the distribution of m is unif= orm over {0,1}^L {{KatzLindell}}.
Since AEAD schemes are semantically secure, we assume each bit of sampled c= iphertext contains one bit
of entropy. Thus, two ciphertexts will collide, possibly leading to nonce r= euse, with probability bounded by
2^(-L/2), i.e., the birthday bound. Use of the same key and nonce more than= once can weaken the
guarantees provided by this protection. For the schemes described, protecti= ng two different packet
numbers with the same key and nonce reveals the exclusive OR of those packe= t numbers, which might be
used to compromise confidentiality.

That's not the scenario I outlined in my comment. You run a server farm and purchase a middlebox from a vendor. If you have a connection ID bit, you don't have to configure the middlebox to align with server policy about connection ID, because packets are self-describing.

I find this whole section hard to understand and hard to implement. I would like to see much more uniformity between the various constructs. I get the following:

  1. We are going to use the same encryption algorithm for PN as the encryption algorithm part of AEAD.

  2. There will be a specific key for PN encryption, different from the key used for data encryption.

  3. The PN encryption will use a 16 byte sample of the packet's ciphertext as nonce.

  4. Our AEAD specification tells us that the nonce is obtained by combining a preset IV with a sequence number. In our case, we will use the first 4 bytes of the sample as a 32 bit sequence number, and the last 12 bytes of the sample as IV, zero padded to the length required by the selected algorithm if necessary.

  5. Conceptually, AEAD algorithm encode an N byte filed by XOR it with a crypto-graphically generated stream of data, plus a 16 byte MAC. When doing PN encryption, we only use the first N bytes of the output, and do not compute or check the MAC. That is, PN encryption uses the "XOR" subset of the AEAD algorithm.

  6. Using only the XOR part of the AEAD algorithm requires specific optimizations depending on the specific AEAD algorithm. These optimizations are presented in the following sections for AES and CHACHA20.

  7. One way to test that a PN encryption implementation is correct is to compute the AEAD encryption of the PN with the selected IV and sequence number, and verify that the AEAD algorithm provides for the same initial bytes as the PN encryption implementation.

Do we agree on that?

I think that's the right formulation: we assume that the AEAD is a PRF. It's not guaranteed to be by the contract, but it's probably true for the AEADs here. Thanks for the text. I'll probably want to make the assumption much more prominent though. Also, the general form here is using AES or ChaCha as a PRF, so that means that we can factor out the cipher-specific parts. I'll see what I can do. -- You are receiving this because you are subscribed to this thread.

+protection to be effective, the output of the packet protection AEAD needs to be
+effectively random.
+
+All the AEAD functions used meet indistinguishability under (adaptive) chosen
+plaintext attack (IND-CPA, IND-CPA2) goals and produce minimal expansion of the
+plaintext, adding only an authentication tag.  Therefore, this document assumes
+that each bit of sampled AEAD output contains one bit of entropy and that an
+attacker is unable to reduce this without knowledge of the key.  Based on this
+assumption, the odds of two samples of ciphertext being identical approach the
+birthday bound for the size of the sample (that is, two to the negative power of
+half the number of sampled bits).

I think that's the right formulation: we assume that the AEAD is a PRF. It's not guaranteed to be by the contract, but it's probably true for the AEADs here. Thanks for the text. I'll probably want to make the assumption much more prominent though. Also, the general form here is using AES or ChaCha as a PRF, so that means that we can factor out the cipher-specific parts.

I'll see what I can do.

Thus, for a short header, +the sampled ciphertext starts at either octet 5 when the connection ID is +omitted, or octet 13 when the connection is present. + +The protected packet might not have produced enough input for the negotiated +packet protection algorithm. This might happen if a packet with a short header +contains minimal data and uses a packet number encoding that is shorter than 4 +octets. Additional zero octets are added to the end of the sequence to reach +the required amount of data. + +Before a TLS ciphersuite can be used with QUIC, a packet protection algorithm +MUST be specifed for the AEAD used with that ciphersuite. This document defines +algorithms for AEAD_AES_128_GCM, AEAD_AES_128_CCM, AEAD_AES_256_GCM, +AEAD_AES_256_CCM (all AES AEADs are defined in {{!RFC5116}}), and +AEAD_CHACHA20_POLY1305 ({{!CHACHA=RFC7539}}). + You can consider this an application of the AEAD, but I think that would be an error. I prefer to think of this as using the same primitives that the AEAD uses. That is, we build AEAD_AES_128_GCM using AES, and so we use AES here. There are commonalities in the design, and I suspect that if you abuse your AEAD interface hard enough, you can get the AEAD to produce the right bits, but that's probably inefficient (you don't need the MAC, but the AEAD will calculate one) and not a general solution (there is no guarantee that the AEAD puts the MAC at the end, or doesn't do other post-processing that would might this design). The reason for that is part of what we sample from the ciphertext of the packet is fed into the counter part and most AEADs don't let you tweak that (all AEADs I've seen have an internal counter that starts from 0 for each invocation).

In draft-ietf-quic-tls.md:

> +assumed to be its largest possible length (4 octets).  Thus, for a short header,
+the sampled ciphertext starts at either octet 5 when the connection ID is
+omitted, or octet 13 when the connection is present.
+
+The protected packet might not have produced enough input for the negotiated
+packet protection algorithm.  This might happen if a packet with a short header
+contains minimal data and uses a packet number encoding that is shorter than 4
+octets.  Additional zero octets are added to the end of the sequence to reach
+the required amount of data.
+
+Before a TLS ciphersuite can be used with QUIC, a packet protection algorithm
+MUST be specifed for the AEAD used with that ciphersuite.  This document defines
+algorithms for AEAD_AES_128_GCM, AEAD_AES_128_CCM, AEAD_AES_256_GCM,
+AEAD_AES_256_CCM (all AES AEADs are defined in {{!RFC5116}}), and
+AEAD_CHACHA20_POLY1305 ({{!CHACHA=RFC7539}}).
+

You can consider this an application of the AEAD, but I think that would be an error. I prefer to think of this as using the same primitives that the AEAD uses. That is, we build AEAD_AES_128_GCM using AES, and so we use AES here.

There are commonalities in the design, and I suspect that if you abuse your AEAD interface hard enough, you can get the AEAD to produce the right bits, but that's probably inefficient (you don't need the MAC, but the AEAD will calculate one) and not a general solution (there is no guarantee that the AEAD puts the MAC at the end, or doesn't do other post-processing that would might this design).

The reason for that is part of what we sample from the ciphertext of the packet is fed into the counter part and most AEADs don't let you tweak that (all AEADs I've seen have an internal counter that starts from 0 for each invocation). We need that counter because the 96-bit nonce doesn't have enough entropy. 128 bits ensures that we don't have to worry about collisions, because we can only send 2^62 packets.

So 1 - shared primitives, not same, 2 - agreed, 3 - this will depend on AEAD, unfortunately, 4 - that's internal AEAD details, 5 - that's AEAD-specific, 6 - see point about shared primitives, 7 - this might be true for the current AEADs if you can abuse them enough, but it's not generally true.

+The protected packet might not have produced enough input for the negotiated
+packet protection algorithm.  This might happen if a packet with a short header
+contains minimal data and uses a packet number encoding that is shorter than 4
+octets.  Additional zero octets are added to the end of the sequence to reach
+the required amount of data.
+
+Before a TLS ciphersuite can be used with QUIC, a packet protection algorithm
+MUST be specifed for the AEAD used with that ciphersuite.  This document defines
+algorithms for AEAD_AES_128_GCM, AEAD_AES_128_CCM, AEAD_AES_256_GCM,
+AEAD_AES_256_CCM (all AES AEADs are defined in {{!RFC5116}}), and
+AEAD_CHACHA20_POLY1305 ({{!CHACHA=RFC7539}}).

I think Kazuho has a plausible generalization with his CTR mode API. Maybe we should find a way to document that.

> +#### Committing to a New Address
+
+When a server receives a packet containing a frame other than PATH_CHALLENGE,
+PATH_RESPONSE, or PADDING from a client address with a packet number that is the
+largest seen thus far on the connection, the server "commits" to this client
+address. The server MUST send all subsequent packets to this address, with the
+following exception.  PATH_CHALLENGE, PATH_RESPONSE, and PADDING frames are used
+for probing a network path, and receiving only these frames MUST NOT cause the
+server to commit to a new address.
+
+Receiving a packet from a new address but with a packet number that is not the
+largest seen thus far suggests that a reordered packet was received and MUST NOT
+cause the server to change its commitment.
+
+Upon committing to a new address, the server SHOULD reset its congestion
+controller and roundtrip time estimator to start new estimations.

At this point it is still possible that a substantial amount of data is outstanding on the "previous" path, this data will be acked on the new path. I suppose that resetting the congestion controller and roundtrip time estimator means that such acknowledgements should be ignored when calculating the congestion window and the SRTT?
This should probably be explicitly stated somewhere.

With gaps, that is possible, for example by using a keyed hash. Assuming that the hash function (H) returns a 32-byte output, you can implement a function like below that checks if a given packet number is represents a gap. ``` // one gap for every 256 packets bool pn_is_gap(const uint8 *key, uint64_t pn) { uint8_t hash[32] = H(key, pn / 256 / 32); return hash[pn / 256 % 32] == pn % 256; } ``` Note that for contiguous ACKs the gap check using a modified version of the function can become very efficient, since you can cache and reuse the result of the hash function. If we are going to switch to a gapless approach, I would prefer having the possibility of generating the entropy at the sender (by using a deterministic function like the one above) and sending it, instead of using some bits that happen to be sent (e.g. the last bit of the AEAD tag). -- You are receiving this because you are subscribed to this thread.

// one gap for every 256 packets

I'll take a look and see = if there's a simple change that would bring us closer, but I also don't wan= t change for change's sake.

The entropy bit gives you that, but is hard to implement. Skipping packets gives you that, because if they don't know when you skip they'll give themselves away. PATH_CHALLENGE doesn't give you that, because it's not bound to the ACK. The problem with PATH_CHALLENGE for this scenario is that the ACK and the PATH_RESPONSE don't have to arrive at the same time. So if the other side is ACK'ing packets that you sent before they've actually arrived in an effort to build up the window, you won't detect it -- the ACK looks legitimate. Now, if they ACK a packet that gets dropped, they'll get caught (eventually, when the timer runs out, assuming the implementation checks whether a packet has been ACK'd when a PATH_CHALLENGE times out) -- but even without doing anything, that will result in missing stream data, which is likely to bite the receiver eventually anyway.

If you want to catch a peer doing early ACKs, there has to be something = that they can only learn from having seen the packets at the time they're s= ending the ACK. The entropy bit gives you that, but is hard to implement. = Skipping packets gives you that, because if they don't know when you skip = they'll give themselves away. PATH_CHALLENGE doesn't give you that, becaus= e it's not bound to the ACK.

The problem with PATH_CHALLENGE for this scenario is that the ACK and th= e PATH_RESPONSE don't have to arrive at the same time. So if the other sid= e is ACK'ing packets that you sent before they've actually arrived in an ef= fort to build up the window, you won't detect it -- the ACK looks legitimat= e.

Now, if they ACK a packet that gets dropped, they'll get caught (eventua= lly, when the timer runs out, assuming the implementation checks whether a = packet has been ACK'd when a PATH_CHALLENGE times out) -- but even without = doing anything, that will result in missing stream data, which is likely to= bite the receiver eventually anyway.

I'm indifferent to which ACK-bound mechanism we use to guard against thi= s -- if we've been told by implementers that packet gaps are easier than en= tropy bits, let's stick with that. But using a mechanism not bound to the = ACK doesn't buy us much we don't already have.

+The protected packet might not have produced enough input for the negotiated
+packet protection algorithm.  This might happen if a packet with a short header
+contains minimal data and uses a packet number encoding that is shorter than 4
+octets.  Additional zero octets are added to the end of the sequence to reach

With the updated text, I understand very well where to pick the sample. That's good. But there is still an issue. You note that "For packets with a short header, the packet number length is not known before decryption". If that is the case, then the receiver has to decode the first PN byte, get the length, then decode the other bytes. That means either two passes of encryption, or doing the XOR manually. Not great.

I would prefer "encrypt from the beginning of the PN to just before the start of the sample". One pass, no fuss.

In draft-ietf-quic-transport.md:

> +#### Committing to a New Address
+
+When a server receives a packet containing a frame other than PATH_CHALLENGE,
+PATH_RESPONSE, or PADDING from a client address with a packet number that is the
+largest seen thus far on the connection, the server "commits" to this client
+address. The server MUST send all subsequent packets to this address, with the
+following exception.  PATH_CHALLENGE, PATH_RESPONSE, and PADDING frames are used
+for probing a network path, and receiving only these frames MUST NOT cause the
+server to commit to a new address.
+
+Receiving a packet from a new address but with a packet number that is not the
+largest seen thus far suggests that a reordered packet was received and MUST NOT
+cause the server to change its commitment.
+
+Upon committing to a new address, the server SHOULD reset its congestion
+controller and roundtrip time estimator to start new estimations.

Excellent point. "Only packets sent on the new path contribute to the state of the congestion control and RTT estimation on that path."

Some frames are simply retransmitted,
-some have their contents moved to new frames, and others are never
-retransmitted.

does not cover that frames can also update content, such as MAX frames.

Yes. IMO that is also a good approach. Anyways, I think that this might be a good opportunity to consider what properties we want to expose to on-path observers when starting to use a new path (i.e. 5 tuple). With variants, packet number encryption and spin-bits, etc., it seems to me that we are starting to explicitly determine what should be observable, at the same time trying to scramble all other properties in order to avoid possible ossification. The same approach can be applied to how we use a path. One option is to expose nothing. If that is the case, pre-1RTT and 1RTT packets should not be easily distinguishable. There could be various approaches in accomplishing that, as @mikkelfj and I have pointed out. Another option is to have a signal that notifies the start of using a new path. In such case, we should expose 1 bit that can be used to distinguish start-of-use vs. in-use. I am not sure if we need (or want to) expose the internals of the handshake (i.e. INITIAL, HANDSHAKE, RETRY). My tendency goes to exposing nothing. The primary reason is that switching to a new path can happen due to NAT rebinding. In such case, it is impossible for a client to mark the first packet that is sent using a new path differently from other packets. Therefore, I believe that we should merge long packet header and short packet header so that pre-1RTT packets would not be easily distinguishable from 1-RTT packets, _if_ ossification is a concern. -- You are receiving this because you are subscribed to this thread.

@ianswett= I could well be wrong, but I do not think that is possible.

The Cookie extension of TLS 1.3 has too purposes:

  • Allowing the server to force the client to demonstrate reachability at = their apparent network address (thus providing a measure of DoS protection)= . This is primarily useful for non-connection-oriented transports (see [RFC= 6347] for an example of this).
  • Allowing the server to offload state to the client, thus allowing it to= send a HelloRetryRequest without storing any state. The server can do this= by storing the hash of the ClientHello in the HelloRetryRequest cookie (pr= otected with some suitable integrity algorithm).
    TLS 1.3 draft 23 section 4.2.2

I do not think that if the cookie is in fact stateless is distinguishabl= e from TLS client's perspective. Therefore, we need to send a signal to the= client at QUIC layer.

To @mcma= nus' suggestion of a stronger signal, yes, if the intent is to mainta= in this rule, then we need a wider API. Frankly, I don't know how to do t= his in practice though.

I think that something like below would work, assuming that the intent= is to force use of Retry packet when the server sends HRR.

  • server-side TLS API provides an option to emit stateless retry when s= ending HRR, and QUIC servers activate that option
    • as an example, picotls already has a boolean flag that enforces such = behavior (sadly, it is called retry_uses_cookie, it should h= ave been named retry_stateless)
  • when observing a Retry packet, a QUIC client should perform stateless= retry
    • this does not change
  • when observing a Handshake packet, a QUIC client must confirm that th= e state of the TLS stack has changed to something that indicates that the= handshake is complete, when the stack emits a message in response

@martinthomson<https://github.com/martinthomson>

To @mcmanus<https://github.com/mcmanus>' suggestion of a stronger= signal, yes, if the intent is to maintain this rule, then we need a wider = API. Frankly, I don't know how to do this in practice though.

I think that something like below would work, assuming that the intent is t= o force use of Retry packet when the server sends HRR.

* server-side TLS API provides an option to emit stateless retry when s= ending HRR, and QUIC servers activate that option
* as an example, picotls already has a boolean flag that enforces su= ch behavior (sadly, it is called retry_uses_cookie, it should have been nam= ed retry_stateless)
* when observing a Retry packet, a QUIC client should perform stateless= retry
* this does not change
* when observing a Handshake packet, a QUIC client must confirm that th= e state of the TLS stack has changed to something that indicates that the h= andshake is complete, when the stack emits a message in response

A server has to pick a consistent minimum. It could occasionally choose longer, but the load balancer would just ignore those extra bytes.

Yes, there is general recognition that a client can't use stateless routing. For a client, you are right. This is why I would prefer some symmetric in connection ID selection, but that means making a hard call with respect to the stateless reset.

I've been reading HTTP/QUIC section 3.4 on Server Push again.

Each Push ID MUST only be used once in a push stream header. If a
push stream header includes a Push ID that was used in another push
stream header, the client MUST treat this as a connection error of
type HTTP_DUPLICATE_PUSH. The same Push ID can be used in multiple
PUSH_PROMISE frames (see Section 4.2.6).

I'd like to clarify if "another push stream header" means:

  1. A STREAM frame received on a different stream ID to the original stream ID.
  2. A duplicate STREAM frame received on the same original stream ID.

I think it's option 1. If its option 2 then I can see issues with receiving duplicate STREAM frames

In regards to the stateless reset issue for asymmetric connection IDs, one use case is picking a connection ID so the packet is received by the optimal receive queue and doesn't have to hop threads/CPUs. For use cases like this, it's an optimization, but the machine should be able to route the packet correctly if it chooses to.

Fixes #756.

Currently, all the discussion about CANCELLED requests is bound up in GOAWAY. While GOAWAY is one way that requests can be CANCELLED, there are others. This lifts out the text about request cancellation to its own section, then shortens the GOAWAY section to reference it.

I don't think there are new normative requirements here, but there are definitely some requirements that are easier to find now.

Sorry to totally randomize things, but several of us had an offline discussion about asymmetric connection IDs, in which each side specifies the connection ID that the other
side should send with. Here's a sketch of what that would look like.

PROTOCOL OVERVIEW
Client Server

Initial [CID=XXX] {recv-CID=YYY} ---------------->
<-------------- Cleartext [CID=YYY] {recv-CID=ZZZ}
Cleartext [CID=ZZZ] ----------------------------->
<-------------------------- Short header [CID=YYY]
Short header [CID=ZZZ] -------------------------->

The initial packet contains:

  • In the header CID field, XXX, which is either
    (a) a randomly chosen dummy CID
    (b) a CID which it received from the server in a stateless reset
  • The transport parameters contain the client's receive CID (YYY in
    the diagram above).

All the server's packets are sent with the client's receive CID and
the transport parameters contain the server's receive CID (ZZZ).

Subsequent packets from the client are sent with the server's receive
CID (ZZZ)

Finally, you can send NEW_CONNECTION_ID in either direction to provide
a new connection ID for the other side to use.

OTHER DETAILS
This design doesn't require variable length CIDs but it's a natural
fit. In particular, it doesn't require the C bit in the long header
because each side gets to indicate exactly how long a CID it wants,
and so sending an empty CID means "don't send me a CID". I haven't
heard a good reason why we should let the packet sender decide whether
to send a CID or not, and so this is largely for the benefit of
middleboxes which doesn't seem like a good reason.

Orthogonally, here's a sketch of a long header with a variable
length CID:

0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

+-+-+-+-+-+-+-+-+---------------+
|0|C|K| Type (5)| CID length |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| |

  •                 [Connection ID (*)]                       +

| |
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Packet Number (8/16/32) ...
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
| Protected Payload (*) ...
+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

Given that the CID is now variable length, we might or might not
want to move it to after the PN.

OPEN ISSUES/PROBLEMS

  1. If the server's handshake gets reordered, the client might need to
    send some ACKs with the initial CID. However, we've agreed that the
    client's IP address has to be stable, so this isn't a
    problem. Alternately, you could change C->S CIDs in the short header
    if that was easier. This might be an argument for the idea of putting
    both CIDs in the long header that I proposed in Melbourne.

  2. Any asymmetric ID scheme inherently makes stateless reset more
    difficult, because the server doesn't have the client's CID. It could
    use a random CID or the server's CID, though. One might not think this
    is so bad because it's really only an issue for a client which needs
    stateless routing of packets (the client itself is of course
    stateful). Previously, this topology was just impossible, so one
    could argue that this was strictly better, as the client will just
    fall back to timeout if the routing fails. Of course, you might
    think that it was really bad too.

I can invent some scenarios, but it would help if you could elaborate a bit. I am also a bit concerned that a client could be configured to use a very small number of connection IDs to all of its QUIC-speaking peers. Since the connection ID is path-visible, that seems like it would have all of the bad possibilities of an observable super cookie (albeit one the server is induced to send, rather than sent along by the client). Obviously, that's a terrible configuration choice, but we have, sadly, seen similar things deployed. Am I misunderstanding the risk there, or is there a way to mitigate you have in mind?

While this is a reasonable sketch of how it would work, it's not clear = from
it what problem you were trying to solve by switching to this. I can
invent some scenarios, but it would help if you could elaborate a bit.

I am also a bit concerned that a client could be configured to use a very small number of connection IDs to all of its QUIC-speaking peers. Since<= br> the connection ID is path-visible, that seems like it would have all of the=
bad possibilities of an observable super cookie (albeit one the server is induced to send, rather than sent along by the client). Obviously, that= 9;s
a terrible configuration choice, but we have, sadly, seen similar things
deployed. Am I misunderstanding the risk there, or is there a way to
mitigate you have in mind?

Here is proposal extracted from that discussion which does not involve packet number encryption. NOTE: this is not a consensus and I am not personally convinced this is best option, but it is one option. The packet number is segmented in a lower 32-bit counter (nonce) and an upper 30+bit path identifier (PID). The packet number is globally unique across all paths and is used directly in ACK frames, but it is never transmitted in clear text on the wire. The lower 32-bit nonce is transmitted in clear text in place of the packet number as a varint. The nonce starts at zero and increments for every packet sent on a given path and a path cease to be valid no later than when the counter reaches 2^32-1. The PID starts at 0 and is incremented for every new path in use. It is not strictly required to increment by one, but each path MUST have a unique PID that is known to both enpoints. There must be a mapping from connection ID to a PID pair. This solution provides dense ACK ranges only having gaps where a new path is in use. The packet number directly identifies that path the packet was transmitted on which could help congestion control. It may be relevant to allow more than 30 bits for the PID range because the packet number space is exhausted relatively fast, but then the packet number cannot be encoded in a 64 bit varint. It is also proposed to use asymmetric CID's so there is a 1-1 mapping from PID to CID, but it is not strictly necessary. (https://github.com/quicwg/base-drafts/issues/1089) Additionally, if each path is given two PID's differing only by only the lower bit, this can be used instead of skipping packet numbers in gapless ACK attack mitigation (https://github.com/quicwg/base-drafts/issues/1092). If the CID is absent, a bit in the header can select which PID is in use. The major upside to the approach 1. Avoids PN encryption which could add an estimated 18% overhead for low-latencey applications. 2. AEAD IV (nonce/packetnumber) not in clear text affects hardware offload and pipelined operation. 3. Reduces ACK fragmentation. 4. Simplifies per path network monitoring 5. Easily handles multi-path. 6. Congenstion control might be easier to handle across paths because the PN identifies its path directly. The major downside to the approach: 1. per path counters could be abused to re-sort packets that shoudn't be (increased latency), but tunneling could do that anyway, so... 2. The packet number space is exhausted faster when constrained to 64 bit varints. -- You are receiving this because you are subscribed to this thread.

There is a long ongoing discussion on the mailing list about packet number encryption.
Here is proposal extracted from that discussion which does not involve packet number encryption.

NOTE: this is not a consensus and I am not personally convinced this is best option, but it is one option.

The packet number is segmented in a lower 32-bit counter (nonce) and an upper 30+bit path identifier (PID). The packet number is globally unique across all paths and is used directly in ACK frames, but it is never transmitted in clear text on the wire. The lower 32-bit nonce is transmitted in clear text in place of the packet number as a varint. The nonce starts at zero and increments for every packet sent on a given path and a path cease to be valid no later than when the counter reaches 2^32-1. The PID starts at 0 and is incremented for every new path in use. It is not strictly required to increment by one, but each path MUST have a unique PID that is known to both enpoints. There must be a mapping from connection ID to a PID pair.

This solution provides dense ACK ranges only having gaps where a new path is in use. The packet number directly identifies that path the packet was transmitted on which could help congestion control.

It may be relevant to allow more than 30 bits for the PID range because the packet number space is exhausted relatively fast, but then the packet number cannot be encoded in a 64 bit varint.

It is also proposed to use asymmetric CID's so there is a 1-1 mapping from PID to CID, but it is not strictly necessary. (#1089)

Additionally, if each path is given two PID's differing only by only the lower bit, this can be used instead of skipping packet numbers in gapless ACK attack mitigation (#1092). If the CID is absent, a bit in the header can select which PID is in use.

The major upside to the approach

  1. Avoids PN encryption which could add an estimated 18% overhead for low-latencey applications.
  2. AEAD IV (nonce/packetnumber) not in clear text affects hardware offload and pipelined operation.
  3. Reduces ACK fragmentation.
  4. Simplifies per path network monitoring
  5. Easily handles multi-path.
  6. Congenstion control might be easier to handle across paths because the PN identifies its path directly.

The major downside to the approach:

  1. per path counters could be abused to re-sort packets that shoudn't be (increased latency), but tunneling could do that anyway, so...
  2. The packet number space is exhausted faster when constrained to 64 bit varints.

In draft-ietf-quic-transport.md:

> +a new client address fails. If the server has no state about the last validated
+client address, it MUST close the connection silently and discard any further
+packets received from the client for this connection.
+
+We note that receipt of packets with higher packet numbers from the legitimate
+client address will trigger another connection migration.  This will cause the
+validation of the address of the spurious migration to be abandoned.
+
+
+### Loss Detection and Congestion Control
+
+The capacity available on the new path might not be the same as the old path.
+
+A client SHOULD reset its congestion controller and roundtrip time estimator
+prior to sending any non-probing packets from a new local address.
+

As discussed earlier, I think it would make sense to add a text like:
"Only packets sent on the new path contribute to the state of the congestion control and RTT estimation on that path."

+The PATH_RESPONSE frame MUST be received on the same local address from which
+the corresponding PATH_CHALLENGE was sent.  If a PATH_RESPONSE frame is received
+on a different local address than the one from which the PATH_CHALLENGE was
+sent, path validation is considered to have failed, even if the data matches
+that sent in the PATH_CHALLENGE.
+
+Thus, the endpoint considers the path to be valid when a PATH_RESPONSE frame is
+received on the same path with the same payload as the PATH_CHALLENGE frame.
+
+The endpoint MAY send additional PATH_CHALLENGE frames to handle packet loss,
+but is subject to the following limit to avoid excessive network load: an
+endpoint SHOULD NOT send more than one PATH_CHALLENGE frame in 200ms.  This
+limit is approximately equivalent to the network load due to a new connection,
+and is based on the initial Handshake Timeout defined in {{QUIC-RECOVERY}}.
+

200ms is probably a sensible value, but for the life-time of the protocol it is hard to say what the network load of a new connection would be, not to mention that it could be totally different depening on the environment.

A different wording could be that is MUST be rate-limited to the estimated connection establishment time, and otherwise 200ms can be used as a default.

In draft-ietf-quic-transport.md:

> +
+An endpoint MAY bundle PATH_CHALLENGE and PATH_RESPONSE frames with other
+frames, as appropriate.  For instance, an endpoint may pad a packet carrying a
+PATH_CHALLENGE for PMTU discovery, or an endpoint may bundle a PATH_RESPONSE
+with its own PATH_CHALLENGE.
+
+
+### Initiating Connection Migration {#initiating-migration}
+
+A client MAY initiate connection migration to a new local address in one of two
+ways.
+
+The client may immediately migrate the connection by sending all packets from
+the new local address.  Receiving acknowledgments for this data serves as proof
+of the server's reachability from the new address.
+

Why is PATH_RESPONSE more strict than ACK's from just sending data wrt. local and remote addresses?

Should there be a rate limit on how often a migration can take place? It might stress the peer, and gaps in packet numbers can be a DoS on the peers implementation (I know gaps are up for discussion, but if/when there are gaps...)

In draft-ietf-quic-transport.md:

> +
+The client may immediately migrate the connection by sending all packets from
+the new local address.  Receiving acknowledgments for this data serves as proof
+of the server's reachability from the new address.
+
+Alternatively, the client may probe for server reachability from the new local
+address first using path validation {{migrate-validate}} and migrate the
+connection to the new address at a later time.  Failure of path validation
+simply means that the new local address is not usable for this connection and
+should not be fatal to the connection when alternative local addresses are
+available.
+
+A client migrating to a new local address SHOULD use a new connection ID for
+packets sent from that address, see {{migration-linkability}} for further
+discussion.
+

Is SHOULD sufficient? One endpoint might not care, but it the other endpoint might.

-consistent connection ID allows connections to survive changes to the client's
-IP and/or port, such as those caused by client or server migrating to a new
-network.  Connection migration allows a client to retain any shared state with a

+QUIC allows connections to survive changes to endpoint addresses (that is, IP
+address and/or port), such as those caused by a client migrating to a new
+network.  This section describes the protocol for migrating a connection to a
+new client address.
+
+Migrating a connection to a new server address is left for future work. If a
+client receives packets from a new server address that are decryptable, the
+client MAY discard these packets.

nit: Why bother decrypting the packets if they're going to be discarded?

In draft-ietf-quic-transport.md:

> +sent, path validation is considered to have failed, even if the data matches
+that sent in the PATH_CHALLENGE.
+
+The PATH_RESPONSE frame MUST be received on the same local address from which
+the corresponding PATH_CHALLENGE was sent.  If a PATH_RESPONSE frame is received
+on a different local address than the one from which the PATH_CHALLENGE was
+sent, path validation is considered to have failed, even if the data matches
+that sent in the PATH_CHALLENGE.
+
+Thus, the endpoint considers the path to be valid when a PATH_RESPONSE frame is
+received on the same path with the same payload as the PATH_CHALLENGE frame.
+
+The endpoint MAY send additional PATH_CHALLENGE frames to handle packet loss,
+but is subject to the following limit to avoid excessive network load: an
+endpoint SHOULD NOT send more than one PATH_CHALLENGE frame in 200ms.  This
+limit is approximately equivalent to the network load due to a new connection,

I think we should try to mimic the handshake retransmission timer as closely as possible and require exponential backoff.

-An endpoint MUST validate that its peer can receive packets at the new address

+It is possible that the client is spoofing its source address to cause the
+server to send excessive amounts of data to an unwilling host.  If the server
+sends significantly more data than the client, connection migration might be
+used to amplify the volume of data that an attacker can generate toward a

+
+Thus, on receiving and decrypting a packet from an unvalidated address, the

+client's possession of the new address.

Where is 4 MSS from? Recovery specifies 2 packets. Also, what if there's no RTT for the new path? Should one use the default or the previous path's RTT?

+
+We note that receipt of packets with higher packet numbers from the legitimate

+
+
+### Loss Detection and Congestion Control
+
+The capacity available on the new path might not be the same as the old path.
+
+A client SHOULD reset its congestion controller and roundtrip time estimator

I think I like Marcus suggestion here. The text seems to presuppose an implementation approach(a single congestion controller that's reset), opposed to specifying the correct behavior.

This is a massiv improvement on the current text.

In draft-ietf-quic-transport.md:

>  
-* The most recent MAX_STREAM_DATA frame for a stream MUST be retransmitted until
-  the receive stream enters a "Size Known" state. Any previous unacknowledged
-  MAX_STREAM_DATA frame for the same stream SHOULD NOT be retransmitted since a
-  newer MAX_STREAM_DATA frame for a stream obviates the need for delivering
-  older ones. Similarly, the most recent MAX_DATA frame MUST be retransmitted;
-  previous unacknowledged ones SHOULD NOT be retransmitted.
+* The current maximum data offset is sent in MAX_DATA frames until acknowledged.

There is no offset in MAX_DATA, so I'm not sure what you mean here.

In draft-ietf-quic-transport.md:

>  
-* BLOCKED, STREAM_BLOCKED, and STREAM_ID_BLOCKED frames SHOULD be retransmitted
-  if the sender is still blocked on the same limit.  If the limit has been
-  increased since the frame was originally sent, the frame SHOULD NOT be
-  retransmitted.
+* The current maximum stream data offset is sent in MAX_STREAM_DATA frames until
+  acknowledged or the receive stream enters a "Size Known" state.  Like
+  MAX_DATA, endpoints need to limit the rate at which this frame is sent.

In this paragraph, and others to follow, do you mean to say that every packet contains this frame from when it's first sent till acknowledgment, or only that it's retransmitted when the carrying packet is declared lost? Whichever it is, I think this could stand to be clearer.

 ### Sending Version Negotiation Packets {#send-vn}
 
 If the version selected by the client is not acceptable to the server, the
 server responds with a Version Negotiation packet ({{packet-version}}).  This
 includes a list of versions that the server will accept.
 
-A server sends a Version Negotiation packet for any packet with an unacceptable
-version if that packet could create a new connection.  This allows a server to
-process packets with unsupported versions without retaining state.  Though
-either the Client Initial packet or the version negotiation packet that is sent
-in response could be lost, the client will send new packets until it
-successfully receives a response or it abandons the connection attempt.
+This system allows a server to process packets with unsupported versions without
+retaining state.  Though either the Initial packet or the version negotiation

Capitalize "Version Negotiation", since that's a packet type. Also, since we're talking about a hypothetical unknown version of QUIC here, we don't actually know that the packet which provokes version negotiation is of type "Initial" -- it might be worth lower-casing that (and maybe just saying "the client's packet" so someone else doesn't try to get you to capitalize it another time!).

In draft-ietf-quic-transport.md:

> +handshake ({{handshake}}).  This commits the server to the version that the
+client selected.
+
+If the packet is a supported version, and a Handshake or 0RTT packet, the
+server MAY buffer a limited number of these packets in anticipation of
+a late-arriving Initial Packet. In the event the server later generates
+a RETRY packet, this buffer should be purged. Servers MUST NOT send packets
+in response to these buffered packets until the Initial packet arrives.
+
+Servers MUST drop incoming packets under all other circumstances.
+
+## Version Negotiation
+
+Version negotiation ensures that client and server agree to a QUIC version
+that is mutually supported. A server sends a Version Negotiation packet in
+response to a packet that might initiate a new connection, see

The point this text was making in the old location might be clearer if you say "in response to each packet", i.e. if the client sends six packets in its first flight, it will get 1 < N <= 6 VN packets back.

In current form of QUIC, a server is allowed to specify any Connection ID that it likes, which may collide with a Connection ID that a client chooses for a new connection.

I believe that a client needs to identify 1 RTT packets by their 5-tuple to avoid the issue.

The description now concentrates on the information that is being repaired in response to perceived loss. This should help avoid the confusion about retransmission. Two new subsections are added to the packetization section. One covers the processing of packets and includes the existing text on processing requirements before acknowledgment. The other includes the retransmission logic. The retransmission section still mentions frame types, but I've tried to make that secondary to the description of the information that is being repaired. I also removed mention of "Regular QUIC packets", which only occurred in 3 places. Closes #463, #765.

Thanks for picking up on my sloppy copy-edits. Please take another look at the MAX_DATA and friends changes. I think that they are much better, but you might disagree.

If you consider how you might implement this, the 0-RTT buffer is likely to be global across the entire server. You can't know when you receive them which connection to associate them with, so it has to be a little bit global. Choosing to send Retry on one connection shouldn't cause other 0-RTT packets to be purged. Also, choosing not to accept 0-RTT is another reason you might purge them. It might be better not to get into details here. I would probably instead maintain a deque of 0-RTT packets and let new 0-RTT packets push older ones out. No point ever purging other than when you are scrubbing through looking for unclaimed packets. Initiating a purge is CPU cycles you don't need to spend. -- You are receiving this because you are subscribed to this thread.

I think that this fits nicely with @marten-seemann's comment about handling Initial packets specially. My pseudocode didn't do this, but this motivates moving the version and Initial packet checks right up front.

+
+If a client receives a packet with an unknown connection ID, and it matches
+the tuple of a connection with no received packets, it is a reply to an
+Initial packet with a server-generated connection ID and will be processed
+accordingly. Clients SHOULD discard any packets with new connection IDs that

+packet, which is handled in accordance with {{handle-vn}}.

Computation isn't the problem, it's receipt of the server handshake. Maybe "packets that are protected with 1-RTT keys prior to receiving handshake messages. Packet protection cannot be removed from these packets until the cryptographic handshake produces the necessary keys."

Yes, Initial packet.

+version, and is long enough to be an Initial packet for some version
+supported by the server, it SHOULD send a Version Negotiation packet as

+server MAY buffer a limited number of these packets in anticipation of

The buffer purge is probably a bad idea. If you consider how you might implement this, the 0-RTT buffer is likely to be global across the entire server. You can't know when you receive them which connection to associate them with, so it has to be a little bit global. Choosing to send Retry on one connection shouldn't cause other 0-RTT packets to be purged. Also, choosing not to accept 0-RTT is another reason you might purge them.

It might be better not to get into details here. I would probably instead maintain a deque of 0-RTT packets and let new 0-RTT packets push older ones out. No point ever purging other than when you are scrubbing through looking for unclaimed packets. Initiating a purge is CPU cycles you don't need to spend.

Yep, looks good. Two nits.

@mikkelfj raised a good point, but I don't see it associated with this paragraph: The most recently sent from for each stream type needs this behavior.

In draft-ietf-quic-transport.md:

> +Due to packet reordering or loss, clients might receive packets for a
+connection encrypted with a key it has not yet computed. Clients MAY drop
+these packets, or MAY buffer them in anticipation of later packets that

+
+
+### Server-Specific Behaviors {#server-specific-behaviors}
+
+If a server receives a packet that has an unknown connection ID, an
+unsupported version, and a sufficient length to be an Initial packet for
+some version supported by the server, it SHOULD send a Version Negotiation
+packet as described in {{send-vn}}.
+
+Servers MUST drop other packets that contain unsupported versions.
+
+If the packet is a supported version, and an Initial packet fully

I think that your previous paragraphs effectively close of all options for not-supported versions, so this is probably a little redundant.

I think that it would be OK for a retransmission of an Initial to be handled statelessly. If that results in progressing to establishing a connection, then I think that it might pay to check if you don't already have one for the same client-chosen connection ID. That is special logic, but probably necessary (unless the server copies the client connection ID).

The description now concentrates on the information that is being repaired in response to perceived loss. This should help avoid the confusion about retransmission. Two new subsections are added to the packetization section. One covers the processing of packets and includes the existing text on processing requirements before acknowledgment. The other includes the retransmission logic. The retransmission section still mentions frame types, but I've tried to make that secondary to the description of the information that is being repaired. I also removed mention of "Regular QUIC packets", which only occurred in 3 places. Closes #463, #765.

> +## Retransmission of Information
+
+QUIC packets that are determined to be lost are not retransmitted whole. The
+same applies to the frames that are contained within lost packets. Instead, the
+information that might be carried in frames is sent again in new frames as
+needed.
+
+New frames and packets are used to carry information that is determined to have
+been lost.  In general, information is sent again when a packet containing that
+information is determined to be lost and sending ceases when a packet
+containing that information is acknowledged.
+
+* Application data sent in STREAM frames is retransmitted in new STREAM frames
+  unless the endpoint has sent a RST_STREAM for that stream.  Once an endpoint
+  sends a RST_STREAM frame, no further STREAM frames are needed.
+

It is not obvious that the endpoint is the local endpoint, or sender unless you are quite familiar with stream state already.

@martin= duke, I agree, we should try to land this and then iterate.

What if the content of Initial #2 differs from Initial #1 (in the same Stream 0 sequence numbers)? What if I process, send a= RETRY, and then it turns out I'd already responded to the Initial with a S= erver Hello?
If I process the second Initial, and then find I already have this connecti= on with 0-RTT, I've passed this stuff up to TLS for no reason. If we check = conn ID first, we've already thrown out the Stream 0 contents as duplicativ= e.

I think that I mentioned that problem before. The client should probabl= y ignore Retry if it has moved on. More generally, we should probably enco= urage (or insist on) consistent routing of Initial. #1115

I made the following changes: 1) Explicitly state the conditions for each possible server action on receipt of the first packet 2) Use IETF terms like "MUST" when missing. 3) Eliminate redundant text 4) Eliminate all explicit mentions of the 1200-byte limit, as this is defined later in the text, where it also explains exactly how to measure packet size. I'm concerned that just saying "1200 bytes" here might cause people to count IP headers or something. Make them read the definition! I don't believe there's any substantive change to the spec.

For handshake the AEAD handles this case, although an explicitly reflected CCID would be helpful in the single port case we do not support.

A client that that has accepted any early server response should lock on to that unique SCID and ignore others. A client MAY reset state and prefer another later arriving server SCID, for example preferring a handshake over a VNEG (an attack from a path observer recently discussed on the mailing list). This avoids the consistent early routing requirement. It may be helpful to avoid this requirement because it is an way way to DoS a single server and because it balances load even if the CCID is not random (as it should be). If we look further out to asymmetric CID's the initial packet sent by client after a retry would be different from an ordinary initial packet because it would route by a SCID and not a CCID.

While GOAWAY is one way that requests can be CANCELLED, there are others. This lifts out the text about request cancellation to its own section, then shortens the GOAWAY section to reference it. I don't think there are new normative requirements here, but there are definitely some requirements that are easier to find now. ----==_mimepart_5a88610cef134_9832b0533843c041648a5-- From nobody Sat Feb 17 09:06:36 2018 Return-Path: X-Original-To: quic-issues@ietfa.amsl.com Delivered-To: quic-issues@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id C8A1E128D2E for ; Sat, 17 Feb 2018 09:06:25 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: 1.153 X-Spam-Level: * X-Spam-Status: No, score=1.153 tagged_above=-999 required=5 tests=[DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1, HTML_IMAGE_ONLY_24=1.282, HTML_MESSAGE=0.001, RCVD_IN_MSPIKE_H3=-0.01, RCVD_IN_MSPIKE_WL=-0.01, SPF_PASS=-0.001, T_RP_MATCHES_RCVD=-0.01, URIBL_BLOCKED=0.001] autolearn=no autolearn_force=no Authentication-Results: ietfa.amsl.com (amavisd-new); dkim=pass (1024-bit key) header.d=github.com Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id Puiv5RUVfinY for ; Sat, 17 Feb 2018 09:06:24 -0800 (PST) Received: from o11.sgmail.github.com (o11.sgmail.github.com [167.89.101.202]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) by ietfa.amsl.com (Postfix) with ESMTPS id AF22E127869 for ; Sat, 17 Feb 2018 09:06:23 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/relaxed; d=github.com; h=from:reply-to:to:cc:in-reply-to:references:subject:mime-version:content-type:content-transfer-encoding:list-id:list-archive:list-post:list-unsubscribe; s=s20150108; bh=PViu+tMvU4DnRTfZWLfnRm/Fwpc=; b=jefi3uqBoiKKvaJL LuxSGapfevJcyxuJArpLblErPeLrn/qImKmZTxdezH2FagKM7HIMlaNsAgeGJyVH pSwqpbzVYndh0WH+bj30sXkej/+lhXSWhHzOQG4F5vRbL8w/t6rTHSdyA4bf0UJ2 SdHpS7ZmUrJmxVeiaXLfuOLsVSU= Received: by filter0609p1iad2.sendgrid.net with SMTP id filter0609p1iad2-25760-5A88610E-A 2018-02-17 17:06:22.510419747 +0000 UTC Received: from github-smtp2a-ext-cp1-prd.iad.github.net (github-smtp2a-ext-cp1-prd.iad.github.net [192.30.253.16]) by ismtpd0014p1iad2.sendgrid.net (SG) with ESMTP id liTdX7d8TMCFA-EuvDUyBg for ; Sat, 17 Feb 2018 17:06:22.450 +0000 (UTC) Date: Sat, 17 Feb 2018 17:06:22 +0000 (UTC) From: Mike Bishop Reply-To: quicwg/base-drafts To: quicwg/base-drafts Cc: Subscribed Message-ID: In-Reply-To: References: Subject: Re: [quicwg/base-drafts] Cancellation of requests with (partial) responses (#756) Mime-Version: 1.0 Content-Type: multipart/alternative; boundary="--==_mimepart_5a88610e64b07_1dfd2b29fa626ed019884e"; charset=UTF-8 Content-Transfer-Encoding: 7bit Precedence: list X-GitHub-Sender: MikeBishop X-GitHub-Recipient: quic-issues X-GitHub-Reason: subscribed X-Auto-Response-Suppress: All X-GitHub-Recipient-Address: quic-issues@ietf.org X-SG-EID: l64QuQ2uJCcEyUykJbxN122A6QRmEpucztpreh3Pak3BXL+aceS68Rir/HAoHemP2VckxegZ6GXw3G ATe0NUtRg5XYcJ4oqp2If2fOAvuysAMds8P7jCsDBMyh4SMQiqgrgL/L2iwf8VAKM7LUce1aR07/vV 0ijrEpNodc2fmKW9hcedr3CZk3QdfS8yiq53mxCdOYeAPGoCwCr3zzs2rg/rzvUxqkq6dQ6mcmta8O c= Archived-At: X-BeenThere: quic-issues@ietf.org X-Mailman-Version: 2.1.22 List-Id: Notification list for GitHub issues related to the QUIC WG List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 17 Feb 2018 17:06:26 -0000 ----==_mimepart_5a88610e64b07_1dfd2b29fa626ed019884e Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Closed #756 via #1100. -- You are receiving this because you are subscribed to this thread.

5.4.2 retry

The server includes a connection ID of its choice in the connection ID field. The client MUST use this connection ID for any subsequent packets that it sends.

I don't think "any subsequent packets" is right.. this applies to subsequent initials, not forever and forever right? (the server, being stateless on the retry, might choose a new cid again in the HANDSHAKE reply)

-The design of the core QUIC transport subsumes many HTTP/2 features, prominent
-among them stream multiplexing.  A key advantage of the QUIC transport is stream
-multiplexing free of head-of-line (HoL) blocking between streams. In HTTP/2,
-multiplexed streams can suffer HoL blocking due to TCP.
-
-If HTTP/2's HPACK is used for header compression, HTTP/QUIC is still vulnerable
-to HoL blocking, because of HPACK's assumption of in-order delivery.  This draft
-defines QCRAM, a variation of HPACK and mechanisms in the HTTP/QUIC mapping that
-allow the flexibility to avoid header-compression-induced HoL blocking.
+This specification defines QCRAM, a compression format for efficiently
+representing HTTP header fields, to be used in HTTP over QUIC. This is a
+variation of HPACK header compression that avoids head-of-line blocking.

"Avoids" is an incorrect term to use: we differentiate avoidance and minimization. In the default mode, QCRAM minimizes head-of-line blocking.

-The design of the core QUIC transport subsumes many HTTP/2 features, prominent
-among them stream multiplexing.  A key advantage of the QUIC transport is stream
-multiplexing free of head-of-line (HoL) blocking between streams. In HTTP/2,
-multiplexed streams can suffer HoL blocking due to TCP.
-
-If HTTP/2's HPACK is used for header compression, HTTP/QUIC is still vulnerable
-to HoL blocking, because of HPACK's assumption of in-order delivery.  This draft
-defines QCRAM, a variation of HPACK and mechanisms in the HTTP/QUIC mapping that
-allow the flexibility to avoid header-compression-induced HoL blocking.
+This specification defines QCRAM, a compression format for efficiently
+representing HTTP header fields, to be used in HTTP over QUIC. This is a
+variation of HPACK header compression that avoids head-of-line blocking.

Agreed. @dtikhonov, would you prefer 'minimizes' here, or do you think we should elaborate?

-The design of the core QUIC transport subsumes many HTTP/2 features, prominent
-among them stream multiplexing.  A key advantage of the QUIC transport is stream
-multiplexing free of head-of-line (HoL) blocking between streams. In HTTP/2,
-multiplexed streams can suffer HoL blocking due to TCP.
-
-If HTTP/2's HPACK is used for header compression, HTTP/QUIC is still vulnerable
-to HoL blocking, because of HPACK's assumption of in-order delivery.  This draft
-defines QCRAM, a variation of HPACK and mechanisms in the HTTP/QUIC mapping that
-allow the flexibility to avoid header-compression-induced HoL blocking.
+This specification defines QCRAM, a compression format for efficiently
+representing HTTP header fields, to be used in HTTP over QUIC. This is a
+variation of HPACK header compression that avoids head-of-line blocking.

As far as abstracts go, the current QCRAM abstract is short. To keep it that way, "seeks to reduce" is probably the best way to go. Discussion about minimization vs. avoidance does not have to be surfaced to the level of the abstract.

In draft-ietf-quic-http.md:

-A HEADERS frame with any flags set MUST be treated as a connection error of type
-HTTP_MALFORMED_FRAME.
+BLOCKING (0x01):

I see this in the same vein as "merge, then fix" -- even if we know the drafts need to change, I want whatever's in the repo at a given commit to be coherent. When we change QCRAM to not use this, it'll disappear from HTTP, and hopefully quickly.

However, a PR to remove it from both would be very welcome. ;-)

Thanks folks, I've addressed comments this far. PTAL. Ian -- happy to add a state machine, which I think is a great idea. But if we can agree on the mechanism, I'd like to consider that a next step and do it after we've got the mechanism in the draft first. > @@ -1477,35 +1481,236 @@ connection if the integrity check fails with a PROTOCOL_VIOLATION error code. ## Connection Migration {#migration} -QUIC connections are identified by their 64-bit Connection ID. QUIC's -consistent connection ID allows connections to survive changes to the client's -IP and/or port, such as those caused by client or server migrating to a new -network. Connection migration allows a client to retain any shared state with a -connection when they move networks. This includes state that can be hard to -recover such as outstanding requests, which might otherwise be lost with no easy -way to retry them. +QUIC allows connections to survive changes to endpoint addresses (that is, IP +address and/or port), such as those caused by a client migrating to a new +network. This section describes the protocol for migrating a connection to a +new client address. + +Migrating a connection to a new server address is left for future work. If a +client receives packets from a new server address that are decryptable, the +client MAY discard these packets. Fair enough, changed text. > +sent, path validation is considered to have failed, even if the data matches +that sent in the PATH_CHALLENGE. + +The PATH_RESPONSE frame MUST be received on the same local address from which +the corresponding PATH_CHALLENGE was sent. If a PATH_RESPONSE frame is received +on a different local address than the one from which the PATH_CHALLENGE was +sent, path validation is considered to have failed, even if the data matches +that sent in the PATH_CHALLENGE. + +Thus, the endpoint considers the path to be valid when a PATH_RESPONSE frame is +received on the same path with the same payload as the PATH_CHALLENGE frame. + +The endpoint MAY send additional PATH_CHALLENGE frames to handle packet loss, +but is subject to the following limit to avoid excessive network load: an +endpoint SHOULD NOT send more than one PATH_CHALLENGE frame in 200ms. This +limit is approximately equivalent to the network load due to a new connection, There's no timer prescribed, which I'd like to avoid prescribing, so exponential backoff is a step after that. I was trying to avoid specifying exactly what the sender should do to detect loss of these packets, but put a safe cap on network load. > + +The PATH_RESPONSE frame MUST be received on the same local address from which +the corresponding PATH_CHALLENGE was sent.

This +limit is approximately equivalent to the network load due to a new connection, +and is based on the initial Handshake Timeout defined in {{QUIC-RECOVERY}}. + 200ms is the default recommended in the recovery draft for new connections. Since this is a new path, there's no info available about this path, hence I'm using the default. > + +An endpoint MAY bundle PATH_CHALLENGE and PATH_RESPONSE frames with other +frames, as appropriate. For instance, an endpoint may pad a packet carrying a +PATH_CHALLENGE for PMTU discovery, or an endpoint may bundle a PATH_RESPONSE +with its own PATH_CHALLENGE. + + +### Initiating Connection Migration {#initiating-migration} + +A client MAY initiate connection migration to a new local address in one of two +ways. + +The client may immediately migrate the connection by sending all packets from +the new local address. Receiving acknowledgments for this data serves as proof +of the server's reachability from the new address. + PATH_CHALLENGE/PATH_RESPONSE is used for reachability tests, to ensure that the reverse path works fine, before migrating data. Sending Data is a bit more aggressive, where the sender is "committing" to the new path without testing it. That said, you raise a good point.

@janaiyengar commented on this pull request.

Thanks folks, I've addressed comments this far. PTAL.
Ian -- happy to add a state machine, which I think is a great idea. But if we can agree on the mechanism, I'd like to consider that a next step and do it after we've got the mechanism in the draft first.

 ## Connection Migration {#migration}
 
-QUIC connections are identified by their 64-bit Connection ID.  QUIC's
-consistent connection ID allows connections to survive changes to the client's
-IP and/or port, such as those caused by client or server migrating to a new
-network.  Connection migration allows a client to retain any shared state with a
-connection when they move networks.  This includes state that can be hard to
-recover such as outstanding requests, which might otherwise be lost with no easy
-way to retry them.
+QUIC allows connections to survive changes to endpoint addresses (that is, IP
+address and/or port), such as those caused by a client migrating to a new
+network.  This section describes the protocol for migrating a connection to a
+new client address.
+
+Migrating a connection to a new server address is left for future work. If a
+client receives packets from a new server address that are decryptable, the
+client MAY discard these packets.

Fair enough, changed text.

In draft-ietf-quic-transport.md:

> +sent, path validation is considered to have failed, even if the data matches
+that sent in the PATH_CHALLENGE.
+
+The PATH_RESPONSE frame MUST be received on the same local address from which
+the corresponding PATH_CHALLENGE was sent.  If a PATH_RESPONSE frame is received
+on a different local address than the one from which the PATH_CHALLENGE was
+sent, path validation is considered to have failed, even if the data matches
+that sent in the PATH_CHALLENGE.
+
+Thus, the endpoint considers the path to be valid when a PATH_RESPONSE frame is
+received on the same path with the same payload as the PATH_CHALLENGE frame.
+
+The endpoint MAY send additional PATH_CHALLENGE frames to handle packet loss,
+but is subject to the following limit to avoid excessive network load: an
+endpoint SHOULD NOT send more than one PATH_CHALLENGE frame in 200ms.  This
+limit is approximately equivalent to the network load due to a new connection,

There's no timer prescribed, which I'd like to avoid prescribing, so exponential backoff is a step after that. I was trying to avoid specifying exactly what the sender should do to detect loss of these packets, but put a safe cap on network load.

In draft-ietf-quic-transport.md:

> +

+the corresponding PATH_CHALLENGE was sent.  If a PATH_RESPONSE frame is received

+endpoint SHOULD NOT send more than one PATH_CHALLENGE frame in 200ms.  This
+limit is approximately equivalent to the network load due to a new connection,
+and is based on the initial Handshake Timeout defined in {{QUIC-RECOVERY}}.
+

200ms is the default recommended in the recovery draft for new connections. Since this is a new path, there's no info available about this path, hence I'm using the default.

In draft-ietf-quic-transport.md:

> +
+An endpoint MAY bundle PATH_CHALLENGE and PATH_RESPONSE frames with other
+frames, as appropriate.  For instance, an endpoint may pad a packet carrying a
+PATH_CHALLENGE for PMTU discovery, or an endpoint may bundle a PATH_RESPONSE
+with its own PATH_CHALLENGE.
+
+
+### Initiating Connection Migration {#initiating-migration}
+
+A client MAY initiate connection migration to a new local address in one of two
+ways.
+
+The client may immediately migrate the connection by sending all packets from
+the new local address.  Receiving acknowledgments for this data serves as proof
+of the server's reachability from the new address.
+

PATH_CHALLENGE/PATH_RESPONSE is used for reachability tests, to ensure that the reverse path works fine, before migrating data. Sending Data is a bit more aggressive, where the sender is "committing" to the new path without testing it. That said, you raise a good point. I've changed some text here.

In draft-ietf-quic-transport.md:

> +
+The client may immediately migrate the connection by sending all packets from
+the new local address.  Receiving acknowledgments for this data serves as proof
+of the server's reachability from the new address.
+
+Alternatively, the client may probe for server reachability from the new local
+address first using path validation {{migrate-validate}} and migrate the
+connection to the new address at a later time.  Failure of path validation
+simply means that the new local address is not usable for this connection and
+should not be fatal to the connection when alternative local addresses are
+available.
+
+A client migrating to a new local address SHOULD use a new connection ID for
+packets sent from that address, see {{migration-linkability}} for further
+discussion.
+

I think this is adequate for now. The section on migration linkability has the real normative text anyways.

In draft-ietf-quic-transport.md:

>  
-An endpoint MUST validate that its peer can receive packets at the new address
-before sending any significant quantity of data to that address, or it risks
-being used for denial of service.  See {{migrate-validate}} for details.
+It is possible that the client is spoofing its source address to cause the
+server to send excessive amounts of data to an unwilling host.  If the server
+sends significantly more data than the client, connection migration might be
+used to amplify the volume of data that an attacker can generate toward a
+victim.
+
+Thus, on receiving and decrypting a packet from an unvalidated address, the
+server MUST immediately validate the client's new address to confirm the
+client's possession of the new address.
+
+Until a client's address is deemed valid, the server MUST limit the rate at
+which it sends data to this address.  The server MUST NOT send more than 4 * MSS

It's a bit arbitrary, but I was shooting for something > min cwnd. Honestly, any number SGTM. Do you prefer min cwnd?

I assumed the initial RTO period implied a default if path RTT was unknown. Happy to clarify if you think it's not clear.

Because only a single stream updates the table, the state of the table is well defined ahead of each instruction. References relative to a base increase the likelihood of programming errors. It is also awkward to use a name-reference that was recently introduced. For instance, if 'custom: b' follows 'custom: a', then the current design requires that the header block be closed after sending 'custom: a' so that 'custom: b' can reference the name. Using the HPACK reference scheme for updates avoids all sorts of problems. It makes it possible to write an update that refers to the most recent update without closing the last transaction and opening a new one.

+
+The protected packet might not have produced enough input for the negotiated
+packet protection algorithm.  This might happen if a packet with a short header
+contains minimal data and uses a packet number encoding that is shorter than 4
+octets.  Additional zero octets are added to the end of the sequence to reach
+the required amount of data.
+
+Before a TLS ciphersuite can be used with QUIC, a packet protection algorithm
+MUST be specifed for the AEAD used with that ciphersuite.  This document defines
+algorithms for AEAD_AES_128_GCM, AEAD_AES_128_CCM, AEAD_AES_256_GCM,
+AEAD_AES_256_CCM (all AES AEADs are defined in {{!RFC5116}}), and
+AEAD_CHACHA20_POLY1305 ({{!CHACHA=RFC7539}}).
+

The CCM mode has a 16 byte header that includes the nonce - it won't be encrypted unless it is taken care of explicitly for that mode and if it isn't encrypted, encrypting the packer number is pointless.

@mikkelfj: I believe you have misunderstood how CCM is used in TLS (and presumably in QUIC).

The inputs to CCM encryption are:

  • A nonce N
  • The key
  • The plaintext
  • The associated data A

The inputs to CCM decryption are:

  • A nonce N
  • The key
  • The ciphertext
  • The associated data A

In some versions of CCM, you explicitly render N on the wire, but in TLS 1.3, you would not do this, but rather (as in AES-GCM), derive it from the PN. There is then no need to render the nonce on the wire, and it behaves as GCM does.

I original found an older RFC 3610, but I then checked TLS 1.3 draft 23 which referred to RFC 5116 which in turn referred via https://tools.ietf.org/html/rfc5116#ref-CCM to NIST https://csrc.nist.gov/publications/detail/sp/800-38c/final appendix A, which lists said header with NONCE - but it wasn't very clearly formulated, so I (apparently incorrectly) assumed it was similar to https://tools.ietf.org/html/rfc3610 except for fixed parameters chosen in the header (as I would have expected).

The problem I have with this approach is that it requires the encoder to make two passes over the headers.

This is a big departure from existing systems. ICE always verifies. TCP always verifies. I think that the important distinction is choice. A client that is moved (because the network moves or rebinds) can keep sending because it's no different to route change in the network. The client didn't move itself, it was moved.

+
+Path validation is used by a server to confirm the client's ownership of a
+new address and by a client to establish reachability to the server from a new
+local address.

Path validation is used by the migrating endpoint to verify reachability of its peer from a new local address. Path validation is used by the peer to verify that the migrating endpoint is able to receive packets sent to that address. That is, that the packets the peer receives do not carry a spoofed source address.

+To start path validation, an endpoint sends a PATH_CHALLENGE frame containing

Is this same-path requirement solely to ensure that reachability is symmetric? Is it to ensure that the frames can be used to measure RTT on the new path? I think that you should say why here.

Same as above.

+The PATH_RESPONSE frame MUST be received on the same local address from which

I think that I agree with Ian. We don't run timers that slowly for ICE any more anyway, and setting a fixed value (wishy-washy 2119 language notwithstanding), is a real issue.

No it doesn't. A server could lie too.

If we want to do this right, we should try to always verify paths before using them. Obviously, when an endpoint migrates without its knowledge, that's not going to happen, so we would need to make allowances for that, but this says that it's OK to just move to a new address and start sending.

This is a big departure from existing systems. ICE always verifies. TCP always verifies.

I think that the important distinction is choice. A client that is moved (because the network moves or rebinds) can keep sending because it's no different to route change in the network. The client didn't move itself, it was moved. But if the client decides to use a different network interface (wifi vs. cellular, for example), then we're into the MUST-validate territory. I think that you need to move that distinction up into the introductory material.

Another case where the distinction between voluntary and involuntary migration is important.

Wow, this invites all sorts of speculation. I think that you need more explanation here.

Some explanation as to why here (the client might have migrated twice), would be good.

+
+After verifying a new client address, the server SHOULD update any address

What does update mean? Does that mean sending them again?

In draft-ietf-quic-transport.md:

-An endpoint MUST validate that its peer can receive packets at the new address

+It is possible that the client is spoofing its source address to cause the
+server to send excessive amounts of data to an unwilling host.  If the server
+sends significantly more data than the client, connection migration might be
+used to amplify the volume of data that an attacker can generate toward a

+
+Thus, on receiving and decrypting a packet from an unvalidated address, the
+server MUST immediately validate the client's new address to confirm the

Everything that Ian said, except that I don't understand why 2xMinCWND. Seems equally arbitrary. MinCWND on the assumption of a default RT[TO] would be more defensible.

> +When an ACK frame is sent, one or more ranges of acknowledged packets may
+be included.  Including older packets reduces the chances previous ACK
+frames were lost, causing spurious retransmits, at the cost of larger acks.
+
+ACK frames SHOULD always acknowledge the most recently received packets,
+and the more out of order packets are, the more important it is to send
+an updated ACK frame quickly, in order to prevent the peer from declaring
+a packet as lost.
+
+Below is one recommended approach for determining what packets to include
+in an ACK frame.
+
+#### Track the most recently acknowledged ACK frame
+
+When a packet containing an ACK frame is sent, the largest acked in that
+frame can be saved.  When a packet containing and ACK frame is acknowledged,

I believe this should be containing and ACK frame -> containing an ACK frame.

Looks fine.

In draft-ietf-quic-recovery.md:

+
+Out-of-order packets SHOULD be acknowledged more quickly, in order
+to accelerate loss recovery.  The receiver SHOULD send an immediate
+ACK when it receives a packet that fills in a gap in the packet numbers
+if it has already acknowledged a larger packet number.  If it has not
+sent an acknowledgement for the larger packet and there are no other
+recent gaps, then it may revert to the standard delayed ack algorithm.
+
+### Ack Ranges
+
+When an ACK frame is sent, one or more ranges of acknowledged packets may
+be included.  Including older packets reduces the chances previous ACK
+frames were lost, causing spurious retransmits, at the cost of larger acks.

No, it reduces the impact of those losses. You can't affect the chance of loss.

In draft-ietf-quic-recovery.md:

> +An acknowledgement MAY be sent for every second full-sized segment,
+as TCP does {{!RFC5681}}, or may be sent less frequently, as long as
+the delay does not exceed the maximum ack delay.  QUIC recovery algorithms
+do not assume the peer generates an acknowledgement immediately when
+receiving a second full-sized segment.
+
+Out-of-order packets SHOULD be acknowledged more quickly, in order
+to accelerate loss recovery.  The receiver SHOULD send an immediate
+ACK when it receives a packet that fills in a gap in the packet numbers
+if it has already acknowledged a larger packet number.  If it has not
+sent an acknowledgement for the larger packet and there are no other
+recent gaps, then it may revert to the standard delayed ack algorithm.
+
+### Ack Ranges
+
+When an ACK frame is sent, one or more ranges of acknowledged packets may

I think at least one range is required, so "may be" is unnecessarily tentative.

In draft-ietf-quic-recovery.md:

+
+ACK frames SHOULD always acknowledge the most recently received packets,
+and the more out of order packets are, the more important it is to send

From this, I would say hyphenate "out-of-order," though my wife disagrees. Your PR, your call. :-)

And perhaps "the more out-of-order the packets are" would help improve readability.

"send an error code" isn't the same terminology we've used elsewhere. I'd use something like "If a server isn't currently accepting any new connections, it SHOULD send a Handshake packet containing a CONNECTION_CLOSE frame with error code SERVER_BUSY."

> +a new client address fails. If the server has no state about the last validated
+client address, it MUST close the connection silently and discard any further
+packets received from the client for this connection.
+
+We note that receipt of packets with higher packet numbers from the legitimate
+client address will trigger another connection migration.  This will cause the
+validation of the address of the spurious migration to be abandoned.
+
+
+### Loss Detection and Congestion Control
+
+The capacity available on the new path might not be the same as the old path.
+
+A client SHOULD reset its congestion controller and roundtrip time estimator
+prior to sending any non-probing packets from a new local address.
+

And the same below for servers, as well.

In draft-ietf-quic-transport.md:

+After successful validation of the client's new address, the server SHOULD reset
+its congestion controller and roundtrip time estimator prior to sending any
+further non-probing packets.
+
+An endpoint MUST NOT restore its send rate unless it is reasonably sure that the
+path is the same as the previous path.  For instance, a change in the client's
+port number is likely indicative of a rebinding in a middlebox and not a
+complete change in path.  This determination likely depends on heuristics, which
+could be imperfect; if the new path capacity is significantly reduced,
+ultimately this relies on the congestion controller responding to congestion
+signals and reducing send rates appropriately.
+
+There may be apparent reordering at the receiver when an endpoint sends data and
+probes from/to multiple addresses during the migration period, since the two
+resulting paths may have different rountrip times.  A receiver of packets on

There are two packets that arrive here. Packet N+1 and packet N. You are referring here to packet N, but you should make that clearer (packet N+1 is also out of order).

Packet N+1 benefits from rapid acknowledgment because it could accelerate retransmission. Packet N benefits from rapid acknowledgment because it could suppress the retransmission triggered by a rapid acknowledgment of packet N+1.

It is customary to use title case for titles, even tiny ones like this. You should make this ### though instead of h4.

This sounds imperative and I don't think that it has to be. The point here is that sending redundant acknowledgments is not especially harmful and a receiver can reduce complexity by doing this.

You should point out that if your largest acknowledged is N and you later receive N-1 (see the above reordering case for that), then dumping the acknowledgment for N-1 will mean also dropping the acknowledgment for N-1.

Is your expectation is that the receiver will acknowledge N-1 immediately? Or is it that you expect loss detection to have triggered for N-1 by the time that the receiver discards the acknowledgments? I think that you need to clearer about expectations here, because the claim here suggests that this is not a problem.

Either way, I think that you want to move this elsewhere (in another PR if you must) and be much clearer about how indexing works. In practice, it is fairly straightforward, but every time I try to read this text, it only makes things worse. The way that I would characterize this: Static indices reference the static table directly. Dynamic indices reference the dynamic table. Because the dynamic table changes constantly, indices are all made relative to a point in the table that doesn't change. This is called the base. The base is a count of the number of insertions into the dynamic table. Base always increases. Header blocks use indices that are relative to a base that is declared at the start of the header block encoding. If the current base of the decoder table is greater than the base associated with an index, then more updates have been added since the encoder created the header block. The index into the current table is increased by the difference. That is: ``` current_index = relative_index + table.base - header_block.base ``` A decoder should always wait until the current base of its table is less than the base of a header block, because this indicates that there are indices in the header block that reference table updates that haven't yet been received. (TODO: decide whether a decoder can force an encoder into a non-blocking mode, or to control how many header blocks can block.) Note that I have used the term "header block" to refer to what goes in HEADERS/PUSH_PROMISE. I think that we should refer to the thing that makes changes to the table as a table update. > @@ -223,15 +319,111 @@ It is an error if the HPACK decoder encounters an indexed representation that refers to an entry missing from the table, and the connection MUST be closed with the `HTTP_HPACK_DECOMPRESSION_FAILED` error code. -## Preventing Eviction Races {#evictions} +### Instructions + +#### Indexed Header Field Representation + +An indexed header field representation identifies an entry in either the static +table or the dynamic table and causes that header field to be added to the +decoded header list, as described in Section 3.2 of [RFC7541]. + +~~~~~~~~~~ drawing + 0 1 2 3 4 5 6 7 ++---+---+---+---+---+---+---+---+ +| 1 | S | Index (6+) | ++---+---------------------------+ This line has only one +. > + +~~~~~~~~~~ drawing + 0 1 2 3 4 5 6 7 ++---+---+---+---+---+---+---+---+ +| 1 | S | Index (6+) | ++---+---------------------------+ +~~~~~~~~~~ +{: title="Indexed Header Field"} + +An indexed header field starts with the '1' 1-bit pattern, followed by the `S` +bit indicating whether the reference is into the static (S=1) or dynamic (S=0) +table.

I think that with this split, we also need a clearer split in terminology.

I propose using "header block" to refer to the representation instructions. That is, the thing that goes in HEADERS/PUSH_PROMISE.

Then "table update" is the thing that goes on the header streams (or control stream if you prefer).

In draft-ietf-quic-qcram.md:

+QCRAM instructions occur on three stream types, each of which uses a separate
+instruction space:
+
+ - Table updates are carried by HEADERS frames on the control stream, as defined
+   by {{QUIC-HTTP}}.  Frames on this stream modify the dynamic table state
+   without generating output to any particular request.
+ - Acknowledgement of header frame processing is carried by HEADER_ACK frames,

+ - Finally, the contents of HEADERS and PUSH_PROMISE frames on request streams

This also simplifies table updates. Is that worth pointing out?

+An addition to the header table starts with the '1' one-bit pattern. If the
+header field name matches the header field name of an entry stored in the static
+table or the dynamic table, the header field name can be represented using the
+index of that entry. In this case, the `S` bit indicates whether the reference
+is to the static (S=1) or dynamic (S=0) table and the index of the entry is
+represented as an integer with an 7-bit prefix (see Section 5.1 of [RFC7541]).
+This value is always non-zero.

Table indices are always non-zero. A zero index is reserved for literal names.

I wonder if it isn't worth your while to include a section on indices and their representation and use. This really needs to be more explicit about the fact that "Index" refers to the dynamic table.

BTW, this section is still basically incomprehensible. Either way, I think that you want to move this elsewhere (in another PR if you must) and be much clearer about how indexing works. In practice, it is fairly straightforward, but every time I try to read this text, it only makes things worse.

The way that I would characterize this:

Static indices reference the static table directly.

Dynamic indices reference the dynamic table. Because the dynamic table changes constantly, indices are all made relative to a point in the table that doesn't change. This is called the base. The base is a count of the number of insertions into the dynamic table. Base always increases.

Header blocks use indices that are relative to a base that is declared at the start of the header block encoding. If the current base of the decoder table is greater than the base associated with an index, then more updates have been added since the encoder created the header block. The index into the current table is increased by the difference. That is:

current_index = relative_index + table.base - header_block.base

A decoder should always wait until the current base of its table is less than the base of a header block, because this indicates that there are indices in the header block that reference table updates that haven't yet been received. (TODO: decide whether a decoder can force an encoder into a non-blocking mode, or to control how many header blocks can block.)

Note that I have used the term "header block" to refer to what goes in HEADERS/PUSH_PROMISE. I think that we should refer to the thing that makes changes to the table as a table update.

+
+An indexed header field starts with the '1' 1-bit pattern, followed by the `S`
+bit indicating whether the reference is into the static (S=1) or dynamic (S=0)
+table. Finally, the index of the matching header field is represented as an
+integer with a 6-bit prefix (see Section 5.1 of [RFC7541]).
+
+The index value of 0 is not used.  It MUST be treated as a decoding error if
+found in an indexed header field representation.

For later: It might be possible to allow an index of 0 for one or other table. The efficiency gains are likely minuscule, but it might simplify some things.

For instance, if it the dynamic table started at zero, then you could populate static[0] with the empty string and condition the name literal on getting the empty string. For me, that would reduce the odd -1 condition (arrays are zero indexed and HPACK is weird), but it might not be worth doing if you have both this and HPACK to worry about.

In draft-ietf-quic-qcram.md:

+The second bit, 'N', indicates whether an intermediary is permitted to add this
+header to the dynamic header table on subsequent hops. When the 'N' bit is set,
+the encoded header MUST always be encoded with this specific literal
+representation. In particular, when a peer sends a header field that it received
+represented as a literal header field with the 'N' bit set, it MUST use the same
+representation to forward this header field.  This bit is intended for
+protecting header field values that are not to be put at risk by compressing
+them (see Section 7.1 of [RFC7541] for more details).
+
+If the header field name matches the header field name of an entry stored in the
+static table or the dynamic table, the header field name can be represented
+using the index of that entry. In this case, the `S` bit indicates whether the
+reference is to the static (S=1) or dynamic (S=0) table and the index of the
+entry is represented as an integer with an 5-bit prefix (see Section 5.1 of
+[RFC7541]). This value is always non-zero.

You can't guarantee that it be non-zero, so you should say what to do if it is zero.

-### Blocked Evictions
+An encoder MUST ensure that an indexed representation is not received by the
+encoder after the referenced entry has already been evicted, and might wish to
+ensure that the decoder will not suffer head-of-line blocking when encoding
+particular references.
+
+In order to enable this, the encoder MUST track outstanding (unacknowledged)
+header blocks on request streams and MAY track outstanding header blocks on the
+control stream.

See above comment about "header blocks" and terminology.

In draft-ietf-quic-qcram.md:

>  
-This replaces the HPACK instruction for Dynamic Table Size Update (see Section
-6.3 of {{RFC7541}}, which is not supported by HTTP over QUIC.
+For header blocks encoded in non-blocking mode, the encoder needs to forego
+indexed representations that refer to vulnerable entries (see
+{{overview-hol-avoidance}}).  An implementation could extend the header table

This notion of vulnerable entries is unnecessarily obfuscation in this design. This is simpler than this: an encoder can't use an insertion until it is acknowledged with HEADER_ACK.

The predecessor QCRAM might have needed this indirection because it coupled different streams together in complicated ways. This is no longer true.

In draft-ietf-quic-qcram.md:

-# Performance considerations
+To track blocked streams, an ordered map (e.g. multi-map) from `Depends Index`
+values to streams can be used.  Whenever the decoder processes a header block on
+the control stream, it can drain any members of the blocked streams map that now
+have their dependencies satisfied.

Why this complication? The encoder only needs to track the number of insertions that have been acknowledged.

It gets more complicated if you want to limit the number of blocked decoders, but I'm not yet convinced that we need that feature. In that case, you only track header blocks that might be blocked and what they block on.

Side-thought sparked by your comment. There are effectively four instructions:

  1. Insert with static table name reference
  2. Insert with dynamic table name reference
  3. Insert with no reference
  4. Duplicate (a.k.a. insert with name+value reference)

We're effectively using two bit prefixes for (1)/(2-3), a sentinel value in the index to differentiate (2)/(3), and (4) gets a single-bit instruction code even though it's the least common.

We could save a few bytes by using two-bit codes for everything and dropping the sentinel zeros for (3), except that HPACK defines string literals to begin on a byte boundary.

+### Duplicate {#indexed-duplicate}
+
+An entry currently in the dynamic table can be re-inserted into the dynamic

That's a separate planned PR. As Alan has noted, there are at least three ways indexes are encoded/used, so it's worth explaining.

-## Header Block Prefix {#absolute-index}
+The frame payload contains contains a variable-length integer (as defined in

Text updated, PTAL.

+
+Below is one recommended approach for determining what packets to include
+in an ACK frame.
+
+#### Track the most recently acknowledged ACK frame
+
+When a packet containing an ACK frame is sent, the largest acked in that
+frame is saved.  When a packet containing an ACK frame is acknowledged,
+the receiver stops acknowledging packets less than or equal to the largest
+acked in the sent ACK frame.  This approach is not sensitive to packet loss
+and allows for over 1 round trip of reordering.

Thanks, I clarified that it's not sensitive to ack loss.

In draft-ietf-quic-recovery.md:

> +## Generating Acknowledgements
+
+QUIC SHOULD delay sending acknowledgements in response to packets,
+but MUST NOT excessively delay acknowledgements of packets containing
+non-ack frames.  Specifically, implementaions MUST attempt to
+enforce a maximum ack delay to avoid causing the peer spurious
+timeouts.  The default maximum ack delay in QUIC is 25ms.
+
+An acknowledgement MAY be sent for every second full-sized segment,
+as TCP does {{!RFC5681}}, or may be sent less frequently, as long as
+the delay does not exceed the maximum ack delay.  QUIC recovery algorithms
+do not assume the peer generates an acknowledgement immediately when

+
+Out-of-order packets SHOULD be acknowledged more quickly, in order
+to accelerate loss recovery.  The receiver SHOULD send an immediate

I tried to clarify this some, see what you think.

In draft-ietf-quic-recovery.md:

> +When an ACK frame is sent, one or more ranges of acknowledged packets may
+be included.  Including older packets reduces the chances previous ACK
+frames were lost, causing spurious retransmits, at the cost of larger acks.
+
+ACK frames SHOULD always acknowledge the most recently received packets,
+and the more out of order packets are, the more important it is to send
+an updated ACK frame quickly, in order to prevent the peer from declaring
+a packet as lost.
+
+Below is one recommended approach for determining what packets to include
+in an ACK frame.
+
+#### Track the most recently acknowledged ACK frame
+
+When a packet containing an ACK frame is sent, the largest acked in that
+frame is saved.  When a packet containing an ACK frame is acknowledged,

Changed to not be imperative and I clarified cases when the peer could miss an acknowledgment.

In terms of loss detection delay, it would be more complex than it's worth, and at this point out of order acks are specified to not be processed in QUIC.

A couple of extra observations.

+Either form of header field name representation is followed by the header field
+value represented as a string literal (see Section 5.2 of [RFC7541]).
+
+
+# Encoding Strategies
+
+## Reference Tracking
+
+An encoder MUST ensure that a header block which references a dynamic table
+entry is not received by the decoder after the referenced entry has already been
+evicted, and might wish to ensure that the decoder will not suffer head-of-line
+blocking when encoding particular references.
+
+In order to enable this, the encoder MUST track outstanding (unacknowledged)
+header blocks and MAY track outstanding table updates.

If you explain why each one is tracked, then you might reach the conclusion - as I did - that 2119 language doesn't make sense here.

The encoder tracks outstanding unacknowledged header blocks so that it can avoid causing evictions that might arrive at the decoder before the entries are needed. The encoder tracks unacknowledged table updates as well so that it can ensure that it never references a table entry that has not been received by the decoder.

In draft-ietf-quic-qcram.md:

You don't actually need to maintain a reference count, it's only one potential way of doing this (admittedly, a pretty reasonable one). I'd prefer not to reference (or assume) a particular implementation strategy here.

Personally, I like having the ACK in the retry packet and think we shoul= d allow it, though, not necessarily require it. But at the very least, the = spec currently has conflicting info in the retry section (5.4.2). At the very beginning it states:

A Retry packet uses long headers with a type value of 0x7E. It carries c= ryptographic handshake messages and acknowledgments.

Then at the end it states:

The payload of the Retry packet contains a single STREAM frame on stream= 0 with offset 0 containing the server=E2=80=99s cryptographic stateless re= try material. It MUST NOT contain any other frames.

I just encountered an interop issue because I only read the top and incl= uded an ACK frame in my Retry and found that ngtcp2 client didn't like it.<= /p>

+### Dynamic Table Size Update
+
+A dynamic table size update signals a change to the size of the dynamic table.

I guess it's implicit that this is the encoder informing the decoder of a change table size, since all of these instructions are in that direction, but mentioning it explicitly might be more clear.

+A dynamic table size update starts with the '001' 3-bit pattern, followed by the
+new maximum size, represented as an integer with a 5-bit prefix (see Section
+5.1 of [RFC7541]).
+
+The new maximum size MUST be lower than or equal to the limit determined by the
+protocol using QCRAM.  A value that exceeds this limit MUST be treated as a
+decoding error.  In HTTP/QUIC, this limit is the value of the
+SETTINGS_HEADER_TABLE_SIZE parameter (see [QUIC-HTTP]) received from the
+decoder.

Do you need to mention that the encoder cannot reduce the size of the table if it would cause entries with non-zero unacknowledged references to be evicted?
