Rather than iterate here, could you instead iterate in the script? It would be more natural to drop the -i thing and iterate over the remaining arguments that getopt doesn't consume.

It can't use the original connection ID, or the one that it used on the path it was probing with the current design.

I found these old comments. I haven't double-checked if they are still valid though.

I agree with Christian about the packet number gap, but I'd like to address that separately.

+PATH_CHALLENGE as a probe or by switching to sending all packets to the new
+address. The client SHOULD do PMTU verification before considering migration
+complete. The client also participates in an address validation that the server
+may initiate to confirm the client's ownership of its address (see
+{{migration-server}}).
+
+A client migrating to a new network might use a new connection ID for packets
+sent from the new address, see {{migration-linkability}} for further discussion.

There's an assumption in the current design that connection IDs are used in series. If a client wants to send on a new path, then it will want to use a new connection ID. But it will then send on the original path, and that will need a different connection ID. It can't use the original connection ID, or the one that it used on the path it was probing with the current design.

With the potential need for multiple probes on the new path, interleaved with continuing packets on the old path, this will consume far more connection IDs than our current design really allows for. Or it will be linkable.

This is where I think packet number encryption/obfuscation will help. It will allow us to switch back to the old connection ID without having to worry about gaps in packet numbers. I think that we will need to fix that.

That doesn't make me think that this is a broken design, only that it reveals that our current design for unlinkability across paths is not suitable any more.

+## PATH_CHALLENGE Frame {#frame-path-challenge}
+
+Endpoints can use PATH_CHALLENGE frames (type=0x0e) to check reachability to the
+peer, to verify a new path's PMTU, and to perform address validation during
+connection migration.

Yeah, I think that the requirement for a minimum size on probes is a requirement on the probing packet, not a property of any particular frame that it contains.

Maybe look at it this way. We have a certain dependency on the connection ID for path verification during the handshake and that is only 64 bits. So, maybe we can reasonably say that 64 bits is enough here as well.

In draft-ietf-quic-transport.md:

+
+The sender of this frame MUST include at least one octet of data in the Data

+
+The recipient of this frame MUST generate a PATH_RESPONSE frame
+({{frame-path-response}}) containing the same Data.  An endpoint that receives a
+PATH_CHALLENGE frame containing an empty payload MUST generate a connection
+error of type FRAME_ERROR, indicating the PATH_CHALLENGE frame (that is, 0x0e).
+
+A PATH_CHALLENGE frame MUST NOT elicit acknowledgements; the corresponding

But frames do elicit acknowledgments. Generally. ACK doesn't. The "MUST NOT" isn't appropriate; it seems like the intent is to say that it doesn't elicit acknowledgment (that is, it's not an interoperability requirement, it's just a property).

I don't think that it makes sense to have special acknowledgment rules for PATH_CHALLENGE though. Acknowledging PATH_CHALLENGE doesn't contribute to path validation, but on the other hand explicitly excluding it creates another exception. I don't see any reason to suppress acknowledgments in this case.

You can drop the , here.

I don't think that we need this check. We need python for xml2rfc.

In Makefile:

The introductory text to the packet size section has some syntax problems:

  • It makes it sound like the Initial packet can be below 1200 Bytes
  • The 1200 Byte restriction could, in principle, apply to an out of order 0RTT packet
  • The "allow receipt" restriction is vague; the new language is IMO more prescriptive.

This appears to be a solid improvement, but I think that we could structure it a little better. This is, I think, a better logical flow: ```c if (short || too_small) { discard_buffer_or_stateless_reset(); } else if (supported_version) { if (initial) { make_new_connection(); } else { discard_buffer_or_stateless_reset(); } } else { send_Version_Negotiation(); } ``` What you have is close to this, but I would merge the handling of packets from a supported version into the same paragraph. I'm also not sure about the logic regarding stateless reset. You don't offer that as an option for a non-initial packet. That might be sensible for the protocol as currently structured, but that assumes that we don't have a use for packets with the long header after connection setup. I don't think that is safe. The logic for deciding whether to discard or buffer might be different for packets of a supported version. For instance, 0-RTT packets might never trigger stateless reset, because you can identify them as being for a new connection and therefore unlikely to be from before you died and were revived. At this level though, we only need to list the valid options and I think that includes stateless reset. > - -If the packet contains a version that is acceptable to the server, the server +a new connection.

@martinthomson requested changes on this pull request.

This appears to be a solid improvement, but I think that we could structure it a little better.

This is, I think, a better logical flow:

if (short || too_small) {
  discard_buffer_or_stateless_reset();
} else if (supported_version) {
  if (initial) {
    make_new_connection();
  } else {
    discard_buffer_or_stateless_reset();
  }
} else {
  send_Version_Negotiation();
}

What you have is close to this, but I would merge the handling of packets from a supported version into the same paragraph.

I'm also not sure about the logic regarding stateless reset. You don't offer that as an option for a non-initial packet. That might be sensible for the protocol as currently structured, but that assumes that we don't have a use for packets with the long header after connection setup. I don't think that is safe.

The logic for deciding whether to discard or buffer might be different for packets of a supported version. For instance, 0-RTT packets might never trigger stateless reset, because you can identify them as being for a new connection and therefore unlikely to be from before you died and were revived. At this level though, we only need to list the valid options and I think that includes stateless reset.

Capitalize "Version Negotiation" when referring to the packet.

Does this need to be a MUST? If the server has sent a Version Negotiation on this flow recently, we should allow suppression. Maybe a "MUST...unless".

I think that we could keep some of the exposition here. Maybe: "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 {{packet-handling}} for details."

-({{packet-initial}}). The details of the handshake mechanisms are described in
-{{handshake}}, but any Initial packet sent from the client to the server MUST
-use the long header format - which includes the version of the protocol being
-used - and they MUST be padded to at least 1200 octets.
-
-The server receives this packet and determines whether it potentially creates a
-new connection (see {{packet-handling}}).  If the packet might generate a new
-connection, the server then checks whether it understands the version that the
-client has selected.
-
-If the packet contains a version that is acceptable to the server, the server
-proceeds with the handshake ({{handshake}}).  This commits the server to the
-version that the client selected.
-
+Clients that support multiple QUIC versions SHOULD pad their Initial packets

Needs a bit more context. "The size of the first packet sent by a client will determine whether a server sends a Version Negotiation packet."

In draft-ietf-quic-transport.md:

> +connection IDs, and long-form packets for connections that have incomplete
+cryptographic handshakes, are associated with an existing connection using the
+tuple of source and destination IP addresses and ports. Other packets are
+associated with existing connections using connection ID the connection ID
+in the header; this might include connection IDs that were advertised using
+NEW_CONNECTION_ID ({{frame-new-connection-id}}).
+
+Clients SHOULD discard any packet that cannot be associated with an existing
+connection.  Discarded packets MAY be logged for diagnostic or security
+purposes.
+
+If a server receives a packet not associated with an existing connection, it

+The server MUST check if the packet uses a short form header, or is not long

Let's avoid using "initial" and instead use "first" here. It could be confused with the packet type.

A few edits to Mikkel's text, but the right ideas are there:

Clients and servers associate packets with an existing or a new connection by using the connection ID if one is present, or the tuple of port-address pairs otherwise. When the connection ID is omitted from short packet headers, correct association requires that the tuple be unique. The tuple might be non-unique when a client reuses the source port, so the connection ID SHOULD be included in the client-to-server direction. A server MAY choose to associate handshake packets using a combination of both the tuple and the client connection ID in order to protect against accidental or intentional collisions. After the handshake completes, the tuple and connection ID might change over the course of the connection; see {{frame-new-connection-id}}) and {{wherever-migration-lives}}.

I'm a little dubious of the "accidental or intentional collisions," though. I think we could reasonably drop that sentence.

Is this included just to emphasize that it's zero-length, or does it actually include a byte representing the zero-length array?

+## The Latency Spin Bit {#spin-bit}

+The latency spin bit enables latency monitoring from observation points on the

Will change the order.

However, since spinning only happens on the short header, I think it needs to be specified like this to handle the case that the server starts sending short header packets before the client does (e.g., because it's done sending all the non-ACK frames it needs to in the 0RTT part of the connection)

Hmm, I meant to check up on this, and now that I have, I don't actually know how <0> would be encoded.

Key updates in TLS are mentioned elsewhere, I think. We don't need to use them.

That was an error. I wish that we had a better defense against optimistic ACK attacks though.

+Packet numbers are not obscured when encoded in frames, such as ACK

+
+These changes are applied before packet protection, so the additional

+These are not true cryptographic confidentiality protections, so entities other

I believe that this is true as qualified. Based on the values of these fields alone there isn't linkability: they are effectively random. There are ways to mess this up (and multipath will definitely risk doing that).

If I remember correctly, one of the use cases for using a new connection ID=

Can we tweak the advice to avoid that, or am misunderstanding the risk here= ?

The definition of PING and PONG frames are ambiguous.

Section 8.9 states:

If the Data field is not empty, the recipient of this frame MUST generate a
PONG frame (Section 8.15) containing the same Data.

Section 8.15 states:

If the content of a PONG frame does not match the content of a PING frame
previously sent by the endpoint, the endpoint MAY generate a connection error of type
UNSOLICITED_PONG.

The way I see it either the MAY in Section 8.15 has to be a MUST to solve this ambiguity or the part in Section 8.9 has to be c hanged into something less strict.
This would be my preferred option since it gives the PING/PONG frames a little bit more semantic leeway.

In line with our established principles for retransmission, I've reworked the
description of packetization. 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.

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.

Ian's proposal is the third rephrasing of the second paragraph, and the differences between them are very subtle. I think the difference is in a handful of corner cases:

  1. a long header comes in on the same conn id as an established connection, but with a different 4-tuple, this might be due to NAT rebinding, or a coincidence (original: assign to established connection; mine: treat it as new; ian: discard it)
  2. same as above, but the same 4-tuple. (original: to established connection; mine: to established connection; ian: discard it)
  3. two clients attempt a handshake with the same conn id (original and mine: 2 separate connections; Ian: these are the same connection)
  4. a client opens two connections simultaneously with the same 4-tuple but different conn ids. (original and mine: same connection; ian: two separate connections)

I slightly prefer Ian's text in the first two, but in 3 and 4 things can get a little hairy when the server changes the connection ID. This whole section gets pretty intricate, and I wonder if we're better off with pseudocode. Or alternatively, under-specify it and provide hosts with a little flexibility to do the right thing for then. I'll do a little more thinking on these corner cases, and welcome further input.

In draft-ietf-quic-transport.md:

> -A packet that uses the short header could be associated with an existing

-0-RTT packets might be received prior to a Client Initial packet at a server.

+with an existing connection, or - for servers - potentially create a new

+Hosts handle packets that can be associated with an existing connection

In that case, I think that we have a problem here.

On the first two, the original needs to be correct or we won't ever be able to use long headers after the handshake completes. For 3 it's always possible for a new client to pick a collision on connection ID (in fact, the odds are surprisingly good at scale), so the original is fine. Only the change in 4 is what was intended.

I don't think it is possible to entirely ignore at tuple even when given an ID. A host may assume an ID is approximately (modulo long time) unique when originating from one source. One peer does not control the ID. Internally it makes sense to hash the tuple with connection ID for lookup. However, it may be sufficient to require the ID be used, since an implementation may decide how tolerant it wants to be agasint collisions.

Writing some pseudocode clarified it, at least for me. I think the ans= wer, in most of the cases above, is just to drop it. If we can agree that= the below is correct, I'll find the language to put in the spec:

Client Processing:

if (short_header)
    if (has_conn_id)

ches)
        use_new_conn_id()
        decrypt()

        drop()

Server processing:

My concern is that shifting from the "omitting connection ID" s= tate to the
"sending connection ID" state could be a signal of imminent con= nection
change. If you can observe all flows going to a destination,
cross-correlating the new flows that show up after this signal with those=
that disappear after this signal seems to provide a potential link. It&#= 39;s
not perfect, of course, but there are traffic patterns where I think it would be real.

If you think this is well understood outside the document, I'm willin= g to
forgo this change, but I don't think the document itself is clear on = this
yet.

Nice work, C in pseudo code :)

It mostly looks good to me, except for where the client upgrades to the = new version id:

else if (tuple_matches && is_first_pkt && version_matche= s)
use_new_conn_id()
decrypt()

The client needs to use the new connection id only after it has got a co= nnection id match. So it would be something along:
client:

I don't think that we need to proscribe a particular software architecture (we're not THAT far gone just yet), but the way that I think of approaching this problem is to start with what the software needs to do first. And for me the first step isn't to just process the packet, but to determine which connection it should be handled by. The code here mixes connection selection into the handing more than I'd like.

Something like: ```python connection = lookup_by_connection_id(packet.connection_id) if connection is None: connection = lookup_by_tuple(packet.address) if connection is not None: connection.handle_packet(packet) return ``` After which you engage the logic for handling packets that don't belong to existing connections, which includes server-side version negotiation. This is what I ended up with when following that to its conclusion: ```python # Lookup by connection ID.

Also, it could probably be factored more cleanly, but it turns out to be quite complicated once you add buffering. I was surprised to see that the addition of multiple connections on the same address tuple didn't complicate things that much if you accept that you want to buffer 1-RTT packets at the client. While that's likely only because of the structure I chose to use here, it's still something of a positive outcome, I guess. When the packet arrives at a connection, you run the version check first. The client has to do version negotiation. This is pretty simple: ```python if not this.version_negotiation_done: # This branch only applies to clients because the server always sets # version_negotiation_done to true before starting. assert(is_client) if packet.version == 0: this.version = pick_version(packet.versions) this.version_negotiation_done = true this.start_over() return false # packet will be discarded if packet.version == this.version: this.version_negotiation_done = true return true # This includes short headers, which we aren't ready for yet. return false if packet.version is not None and packet.version != this.version: return false # discard it return true # OK to process this packet ``` Noting that this doesn't handle the case where the client needs to buffer 1-RTT, so any potential buffering check needs to come before this is run. And then it's on to the standard processing, decryption and so forth. There's also a bunch of tail-end processing necessary, such as that needed to maintain the lookup tables, and that needs to be conditional on the success of the decryption, but that's an exercise for the reader. One thing that I think is important is that I barely pay attention to whether the packet is long or short in this logic. Though that determines whether or not we have a version field in the packet (and thus whether we consider the version supported), and similarly whether the connection ID might be absent, that effect is constrained to those places that check those fields. Otherwise the code doesn't care about packet format. -- You are receiving this because you are subscribed to this thread.

    return false # discard it

return true # OK to process this packet

Noting that this doesn't handle the case where the client needs to buffe= r 1-RTT, so any potential buffering check needs to come before this is run.=

And then it's on to the standard processing, decryption and so forth. T= here's also a bunch of tail-end processing necessary, such as that needed t= o maintain the lookup tables, and that needs to be conditional on the succe= ss of the decryption, but that's an exercise for the reader.

One thing that I think is important is that I barely pay attention to wh= ether the packet is long or short in this logic. Though that determines wh= ether or not we have a version field in the packet (and thus whether we con= sider the version supported), and similarly whether the connection ID might= be absent, that effect is constrained to those places that check those fie= lds. Otherwise the code doesn't care about packet format.

A server can remember the transport parameters that it advertised, or store=
an integrity-protected copy of the values in the ticket and recover the
information when accepting 0-RTT data. A server uses the transport
parameters in determining whether to accept 0-RTT data.

So its choices are "honor the transport parameters" and "rej= ect 0-RTT
data", and I believe there are cases where it may need to do both. In=
particular, if it has to turn off a feature that is negotiated uses a
transport parameter, it likely has to move to "reject 0-RTT data"= for any
ticket that uses the transport parameter to invoke that feature (see
section 7.3 for the related text on new transport parameters being used to<= br> invoke new features).

So there are three choices: it can remember the parameters for the validity=
period, store them in the ticket, or refuse 0-RTT.

If it doesn't know them (because it didn't store them in the ticket= and
doesn't remember them), then it has to refuse 0-RTT.

I think these are the right three choices, so if we need more text to cover=
your questions and Ian's similar question, then we should draft a longe= r
exposition. If you think these are the wrong choices, of course, that'= s a
different matter.

We now have encryption providing the primary proof of receipt for the Initial packet. Allowing the server to pick a new connection ID and include that in the Retry packet header allows servers to steer clients. Closes #713, #1041.

I like the proposal. We need something like that for enabling experiments. But I would like to see a range of type values "reserved for experimentation", to avoid "reserve by squatting".

+The "QUIC EXTENSION Frame Types" registry governs a 16-bit space.  Values are

The spec was cool until that point. But there is a need to allow for experiments "between consenting implementations". What are they going to do? Squat on unallocated values? Or do we want to have an explicit range of extension types reserved for experiments, say FF00 to FFFE?

@mikkelfj asks whether the exemption of stream 0 also means that data counts towards MAX_DATA limits.

In other words, choose between:

  • data sent on stream 0 counts as data sent, but it is permitted to exceed flow control limits
  • data sent on stream 0 does not count as data sent for the purposes of flow control

I assume that you intend to use the IANA considerations from the other PR? Because this isn't complete until you have that. > + +During the handshake, the client may offer the server a list of extensions it +supports as a part of transport parameters, and the server may reply with the +list of extensions it has accepted. + +Every extension that defines a codepoint in the transport parameters extension +list MUST have a well-defined and ordered list of new frames it provides (that +list MAY be empty), as well as the rules for parsing said frames. The extension +frame codepoints are allocated by assigning the frame numbers in order starting +from 0x80, where the order is defined first by the order of extensions as +specified in the server handshake, and then by the order they are specified in +the extension definition. So, for instance, consider the situation where there +are two extensions, A and B; extension A defines frames A1 and A2, in that +order, and extension B defines only the frame B. Then server accepting "A, B" +results in assignment "0x80 = A1, 0x81=A2, 0x82 = B", whereas "B, A" would +result in "0x80 = B, 0x81 = A1, 0x82= A2". As Christian says, it would make sense to have the client offer a list of the things that it supports (a list of extension points) and the server to indicate assignments (a list of frame type to extension point mappings). That leaves Mike's concern. We haven't committed to having a negotiation pattern where the client speaks first. This would make that commitment. If you want to avoid that, you could say that the mapping needs to be respected by the receiving peer. That is, the client advertises a mapping of extension frame codepoint to frame octet and the server uses that for frames that it sends to the client. The server might advertise a different mapping and the client would have to respect that too. That's a tiny bit more complicated, but probably still feasible. Finally, with either suggestion, you don't have to limit extension frames to the 0x80-0xff range. You can use any codepoint. > @@ -1217,6 +1218,17 @@ ack_delay_exponent (0x0007): value is also used for ACK frames that are sent in Initial, Handshake, and Retry packets.

I assume that you intend to use the IANA considerations from the other PR? Because this isn't complete until you have that.

In draft-ietf-quic-transport.md:

> +
+During the handshake, the client may offer the server a list of extensions it
+supports as a part of transport parameters, and the server may reply with the
+list of extensions it has accepted.
+
+Every extension that defines a codepoint in the transport parameters extension
+list MUST have a well-defined and ordered list of new frames it provides (that
+list MAY be empty), as well as the rules for parsing said frames.  The extension
+frame codepoints are allocated by assigning the frame numbers in order starting
+from 0x80, where the order is defined first by the order of extensions as
+specified in the server handshake, and then by the order they are specified in
+the extension definition.  So, for instance, consider the situation where there
+are two extensions, A and B; extension A defines frames A1 and A2, in that
+order, and extension B defines only the frame B.  Then server accepting "A, B"
+results in assignment "0x80 = A1, 0x81=A2, 0x82 = B", whereas "B, A" would
+result in "0x80 = B, 0x81 = A1, 0x82= A2".

As Christian says, it would make sense to have the client offer a list of the things that it supports (a list of extension points) and the server to indicate assignments (a list of frame type to extension point mappings).

That leaves Mike's concern. We haven't committed to having a negotiation pattern where the client speaks first. This would make that commitment. If you want to avoid that, you could say that the mapping needs to be respected by the receiving peer. That is, the client advertises a mapping of extension frame codepoint to frame octet and the server uses that for frames that it sends to the client. The server might advertise a different mapping and the client would have to respect that too. That's a tiny bit more complicated, but probably still feasible.

Finally, with either suggestion, you don't have to limit extension frames to the 0x80-0xff range. You can use any codepoint.

In draft-ietf-quic-transport.md:

varints create a strong incentive to pick from the first 64 values. I don't think that we need that much space. 16 bits is plenty for two reasons: experience with TLS shows that the rate of adding new codepoints is low enough that collisions and experiments collide infrequently; I don't want to create undue incentive to pick values <64 to get the short varint encoding.

Since that interpretation is directly in conflict with the next sentence, I think that this sentence is just unclear about intent (TLP isn't special when it comes to its sending and handling, the only special handling is in deciding to send a TLP packet - and maybe what you put in that packet).

It consolidates the description of QHKDF-Expand and corrects a bunch of minor things related to key derivation and expansion. This is the parts of #1043 that I wanted to keep. The only non-editorial change is a change to the handshake salt used to derive handshake keys. That should keep the fresh.

This is an almost purely editorial change. It consolidates the description of
QHKDF-Expand and corrects a bunch of minor things related to key derivation and
expansion. This is the parts of #1043 that I wanted to keep.

The only non-editorial change is a change to the handshake salt used to derive
handshake keys. That should keep the keys fresh.

Closes #1043.

I am not convinced this timing attack protection is worthwhile. There is no argument on how an attacker might do the timing. There is no immediately observable reply, and an ACK would not happen just because the packet was guessed. It could affect ACK of a valid packet and a powerful attack could delay valid packets to measure timing. But this must be balanced against the value of guessing the packet number. The value can lead to tracking a migration, but so can tons of other fingerprints.

In conclusion, requiring that a full AEAD validation is performed on essentially all invalid packet headers seems to be unreasonable. However, if it isi important, I would MUCH rather prefer a short 16-bit header validation tag that can quickly reject any invalid header in case of a flood attack.

> +## Packet Number Protection {#pn-encrypt}
+
+QUIC packets are protected using a key that is derived from the current set of
+secrets.  The key derived using the "pn" label is used to protect the packet
+number from casual observation.  The packet number protection algorithm depends
+on the negotiated AEAD.
+
+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.
+

If packet number protection (for good reasons) is only applied after handshake, this prevents connection migration from looking like a new handshake unless there are special rules for packet numbering during a handshake. Hence, perhaps protetected packet numbers should have a separate numbering space.

There's obviously no requirement to generate PING frames, but handling them is part of compliant ACK generation.

> +## Packet Number Protection {#pn-encrypt}
+
+QUIC packets are protected using a key that is derived from the current set of
+secrets.  The key derived using the "pn" label is used to protect the packet
+number from casual observation.  The packet number protection algorithm depends
+on the negotiated AEAD.
+
+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.
+

As it stands now, connection migration in no way looks like a new connection, because no long form handshake packets are used on the new path.

Q: If we encode the packet number length inside the encryption, which seems nice, does the decrypter have to assume the longest possible packet number length, then check the first byte after decryption to determine the actual length?

Since the encryption is XOR based, it suffice to decrypt the first byte with XOR to decide the length, or, just the first two bits, actually.

+secrets.  The key derived using the "pn" label is used to protect the packet
+number from casual observation.  The packet number protection algorithm depends
+on the negotiated AEAD.

As it stands now,

I was thinking a bit ahead - considering the open issue(s?) on the topic.

> +## Packet Number Protection {#pn-encrypt}
+
+QUIC packets are protected using a key that is derived from the current set of
+secrets.  The key derived using the "pn" label is used to protect the packet
+number from casual observation.  The packet number protection algorithm depends
+on the negotiated AEAD.
+
+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

The initial handshake needs to negotiate encryption and hence cannot encrypt those packets.

Perhaps the packet numbers ought to be encrypted with a version specific non-negotiably algorithm, but that hurts devices that doesn't speak AES natively. This is why I suggest each handshake and migration sequence uses unencrypted, from 0, packet numbers, unique to each connection ID.

I knew that this would raise eyebrows :)

Early discard doesn't give any better protection against denial of service. The space of valid packet numbers is >= 50% of the total expressible space, which - with the type outside of protection as it currently is - can be 2^32. That number doesn't go down with guesses. That means that an attacker can always force the receiver to do a full AEAD. Given that, the cost of full side-channel resistance is marginal.

As for observing the timing of a discarded packet, I agree that it is hard. Of course, there is always the next packet.

+## Packet Number Protection {#pn-encrypt}

What @mikkelfj says. Say we choose an encoding with a 4 octet maximum length, then you copy 4 octets out, XOR those, then decode from that buffer. You then know the length and can discard the excess.

In draft-ietf-quic-tls.md:

> +## Packet Number Protection {#pn-encrypt}
+
+QUIC packets are protected using a key that is derived from the current set of
+secrets.  The key derived using the "pn" label is used to protect the packet
+number from casual observation.  The packet number protection algorithm depends
+on the negotiated AEAD.
+
+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 biggest problem for having migration appear to be a new connection is that the packets won't decrypt with the handshake keys. This doesn't change any of that. @mikkelfj separately suggested that we use 0-RTT, and that could work, but it's a pretty big lift.

 determining the cryptographic nonce for packet encryption.  Each endpoint

Fixes #1074, #725 - these are similar problems around flow control on stream zero.

Stream 0 isn't bound to obey connection-level flow control, which necessarily means that it can't consume connection-level flow control either. That was previously incorrect, since the definition of connection flow control repeatedly referred to "all streams."

On the other hand, Stream 0 can get stalled by stream-level flow control and the client isn't allowed to give it more credit. This permits Stream 0 to "surge" until the end of the handshake, but then it has to wait for the client to give it more credit until it catches up.

Finally, that surge could provoke an amplification attack if a server has a really large handshake message. The proposed mitigation to that is to require address validation before sending more than N times the client's initial packet size; since the client has an initial minimum packet size, that can be simplified to N Handshake packets from the server. I've arbitrarily chosen N=3, but happy to bikeshed that. I'm not certain I've landed that restriction in the best place, so feel free to suggest moving it elsewhere entirely.

This leaves the exemption to the stream-level flow control for Initial and
Retry packets only (previously it was Initial only). But, to address the
possibility that the flow control limit is too small for the entire handshake
it permits the sending of MAX_STREAM_DATA (and STREAM_BLOCKED) during the
handshake.

+stream 0 is not counted against the limit expressed by MAX_DATA.  Data on =

+multiple packets, so there is no opportunity for a peer to send MAX_STREAM=

Given that ACK frames don't reference a stream, the idea of an ACK frame= for stream 0 seems undefined. If that phrase wasn't supposed to apply to = the ACK frames as well, then I'm having trouble parsing it.

Actually, no, they can't -- ClientHello has to fit in the single Initial= packet, which you say on 3280 doesn't count against this limit, so who car= es?

A client might exceed this limit in a Handshake packet, if the handshake= takes more than 1 RTT (or the Client Finished is huge for some reason, I s= uppose), though. Is that what you're after?

Hm. Retry is fine, because you're resetting the transport in between, i= ncluding all the stream states and contents.

But Initial? You'll have different STREAM frames from different packets= identifying the range [0,length) on stream 0 containing different data, an= d the logic to drop duplicate data needs to not drop it on stream = 0? Ick.

If this is the direction you want to go, I'd almost rather see a custom = Handshake frame type and let 0 go back to being normal and application-owne= d. This direction feels really weird.

In draft-ietf-quic-tls.md:

But isn't the whole problem here that tampering with these packets can't= be detected? An attacker could cause one side to believe that it had a hu= ge flow control window on stream 0, which could then cause the connection t= o blow up at some future point if they attempted to send to that limit. Su= bsequent, lower MAX_STREAM_DATA frames would be ignored, because they don't= increase the largest-seen value.

@MikeBishop, if your solution had any chance of working, I would prefer it also. But your arbitrary limit cannot work.

I can see the point for a Retry, in which case both peers will forget (or ignore as invalid) the first set of Initial packets. There's a nasty gotcha there (#1085), but that probably isn't what you are talking about here.

Ah, I see what you're getting at. You're trying to warn that, if there's a Retry, the First Initial and Second Initial will both contain ClientHellos at offset zero, and Retry and the server's Handshake will both contain data starting at offset 0. I got a totally different interpretation of what you wrote, clearly.

I'd either drop the note, or simply point to the section on Retry with a reminder that the transport state, including stream contents, gets reset following a Retry.

I think if you change Initial to Handshake, this is fine.

> +## Packet Number Protection {#pn-encrypt}
+
+QUIC packets are protected using a key that is derived from the current set of
+secrets.  The key derived using the "pn" label is used to protect the packet
+number from casual observation.  The packet number protection algorithm depends
+on the negotiated AEAD.
+
+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.
+

Yes that is true - in 0-RTT the packet numbers could be encrypted.

BTW: if 0-RTT doesn't actively take measures to avoid fingerprinting, that would be an excellent way to track users. This somewhat relates to the replay thing.

A number isn't meaningful if the CID carries routing paths. It's just a byte sequence.

+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.

Instead of zero padding, the input could sampled from protected packet content including cipher text and, for short cipher text, also the authentication tag.

But

I don't like that it is not possible to do AEAD verification in-place without modifying the packet content. Thus AEAD should cover the encrypted packet number, not the plain text packet number. However, then it does not work to use the cipher nor the tag as input.

@mikkelfj

Instead of zero padding, the input could sampled from protected packet content including cipher text and, for short cipher text, also the authentication tag.

The issue is that it is impossible to tell where the ciphertext or the authentication tag begins, assuming that the length of the packet number field will become part of the protected packet number.

Consider the case where we have protected packet number (1 octet), ciphertext (1 octet), tag (16 octets).

The length of the packet number is encoded within the protected packet number. We need to find entropy from the octets that are guaranteed to be not part of the protected packet number.

The text in the PR proposes to take from the fifth octet of the encrypted triplet (i.e. protected packet number, ciphertext, tag). That would mean that the minimum length of the entropy would be 14 bytes.

I don't like that it is not possible to do AEAD verification in-place without modifying the packet content.

My assumption was that we would nevertheless be required to modify the packet header before feeding it as AAD to AEAD, assuming that we would either have greasing (in the packet header) or at least one spin bit. Is that no longer the case?

In draft-ietf-quic-tls.md:

> +on the negotiated AEAD.
+
+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.

The issue is that it is impossible to tell where the ciphertext or the authentication tag begins

I see. But I don't think it would be a big deal to expose the length bits in clear text. But then again, zero padding is also fine.

My assumption was that we would nevertheless be required to modify the packet header

I would assume you could apply AEAD after spin bits etc.. However, packet numbers are different because they are the IV for the AEAD itself and because their encryption is derived from the same AEAD.

This is definitely a much cleaner design than overloading PING as I did.

I think that we can remove this last sentence now that PATH_CHALLENGE is fixed size. FWIW, I think that we could drop back to 8 happily. 12 raised some eyebrows, and the handshake uses fewer octets. That said, 12 means that you could include 8 octets of randomness and a timestamp - or a timestamp and an 8 octet HMAC - so that you don't have to maintain state and you can still measure RTT.

Split the last clause here into a new sentence: Using fresh values allows the endpoint to measure the time taken to respond to a challenge.

Rather than SHOULD here, I think that you need to talk about sending multiple to deal with the potential of loss, but limiting the total time or number of challenges and eventually giving up.

In draft-ietf-quic-transport.md:

-## PONG Frame {#frame-pong}
+Endpoints can use PATH_CHALLENGE frames (type=0x0e) to check reachability to the
+peer, to verify a new path's PMTU, and for address validation during connection

I think that you should drop the PMTU bit here. It's the packet size that determines PMTU validity anyway.

In draft-ietf-quic-transport.md:

-The PONG frame (type=0x0d) is sent in response to a PING frame that contains
-data.  Its format is identical to the PING frame ({{frame-ping}}).
+PATH_CHALLENGE frames contain a variable-length payload.

A fixed size is better. No chance of messing it up that way. As I said above, I think that 12 octets is pretty good (that's the size of the STUN transaction ID).

In draft-ietf-quic-transport.md:

>  
-An endpoint that receives an unsolicited PONG frame - that is, a PONG frame
-containing a payload that is empty MUST generate a connection error of type
-FRAME_ERROR, indicating the PONG frame (that is, 0x10d).  If the content of a
-PONG frame does not match the content of a PING frame previously sent by the
-endpoint, the endpoint MAY generate a connection error of type UNSOLICITED_PONG.
+
+The sender of this frame MUST include at least one octet of data in the Data

To the above, one octet is of almost no value. You would need many PATH_RESPONSE frames.

-containing a payload that is empty MUST generate a connection error of type

When? If the secondary value of PATH_CHALLENGE is to be realized, this should be done immediately. Or are we expecting the ACK frame to include ACK Delay and we expect challengers to use that to correct their view of path delay? With the potential for the ACK or response to follow a different path, it's hard to know how reliable this will be for measuring path RTT.

I'm with Ian here. I think that we can treat this frame as normal. I can see how you might want to exclude PATH_RESPONSE from acknowledgment, but even there I would just let the ACKs flow.

+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'm not sure what your proposal is there. What I have described takes at least 14 octets always. I think that's enough, even with the birthday bound on 112 bits being pretty low: with AES you have to re-key long before you hit that many packets, and I'd say that you'd want to do the same with ChaCha even if it remains cryptographically sound for far longer.

Does this mean that the TLP doesn't count towards bytes_in_flight?

This is answered by section 3.1.1:

A TLP packet MUST NOT be blocked by the sender=E2=80=99s congestion cont= roller. The sender MUST however count these bytes as additional bytes in fl= ight, since a TLP adds network load without establishing packet loss.

OTOH, I think as an implementer I'd like to have some leeway on this. MU= ST might be too strong.

Trying to cram sufficient routing state into a 64-bit identifier is tricky, especially since that information needs to be encrypted and probably also authenticated (at least a little). Using a block cipher would be ideal, but all the 64-bit ciphers are pretty bad, whereas all the 128-bit ones are both faster and more available. The extra 8 bits is for accounting. If you want to manage key rotation, a key identifier is helpful. Having extra space allows for that to be added without forcing the block cipher to protect less than 128 octets, which can be hard. The way that packet overheads are managed are different for long and short headers. In long headers, the overheads are much higher, but we don't send many of those, so it's not a big deal. For short headers, each endpoint sends a truncate_connection_id transport parameter which sets the length of the connection ID that will be used in short headers. Each endpoint sets their own limit and their peer has to follow this limit. Anywhere from 0 (no connection ID) to 17 (all of the connection ID) can be set. This also closes the discussion about whether connection ID is a number or not. With truncation, treating it as a number no longer makes sense. Note that this change shows the corresponding changes to the invariants draft on the assumption that it will need to be changed at the same time.

This comes out of the discussion about what it takes to construct a se= nsible
connection ID for NEW_CONNECTION_ID. Trying to cram sufficient routing s= tate
into a 64-bit identifier is tricky, especially since that information nee= ds to
be encrypted and probably also authenticated (at least a little). Using = a
block cipher would be ideal, but all the 64-bit ciphers are pretty bad, w= hereas
all the 128-bit ones are both faster and more available.

The extra 8 bits is for accounting. If you want to manage key rotatio= n, a key
identifier is helpful. Having extra space allows for that to be added wi= thout
forcing the block cipher to protect less than 128 octets, which can be ha= rd.

The way that packet overheads are managed are different for long and s= hort
headers. In long headers, the overheads are much higher, but we don't se= nd
many of those, so it's not a big deal. For short headers, each endpoint = sends
a truncate_connection_id transport parameter which sets the length of the=
connection ID that will be used in short headers. Each endpoint sets the= ir own
limit and their peer has to follow this limit. Anywhere from 0 (no conne= ction
ID) to 17 (all of the connection ID) can be set.

This also closes the discussion about whether connection ID is a numbe= r or not.
With truncation, treating it as a number no longer makes sense.

Note that this change shows the corresponding changes to the invariant= s draft
on the assumption that it will need to be changed at the same time. We c= an take
this before adoption, but it will need to be rebased if we do.

Should these fall after ACK frames in terms of ordering?

I didn't think that we previously intended a packet containing only a PATH_CHALLENGE frame to be acknowledged, but I think that could make sense.

Minor question though:
What if we get a PATH_RESPONSE, but no ACK? Do we then retransmit the PATH_CHALLENGE?

The previous comment about the packets potentially being sent on (or taking) different paths is interesting, because we could ACK along the current path, but send the PATH_RESPONSE along the same path the PATH_CHALLENGE came in on. This could provide valuable information to the endpoint about the viability of those two paths, although we still end up in the situation of a rapidly failing path causing the ACK to not be delivered, which is not the end of the world.

If we require the PATH_RESPONSE to be sent on the same path as the PATH_CHALLENGE, do we place any requirements on the ACK? And does such a requirement make sense?

Do we really need to error out if a response if received for a challenge we don't have saved at the moment? What if the sender of the challenge ended up timing out the packet too aggressively and threw away its state for it? If we really need to reliability validate this, how long would the sender of the challenge need to keep this state around then?

@MikeBishop commented on this pull request.

I like the property that the "real" CID is fixed-size and it gets shortened in certain circumstances. However, I'm concerned that having no indication of CID presence or length in the short header limits the usefulness of the CID for routing for any network appliance not in explicit cooperation with the server. That seems like it has the potential to bite us.

If you have one more bit, you now have 64 packet types.

This makes the Connection ID in the short header a difficult invariant. There might be one, but there's no way to identify how long it is. Middleboxes that want to use the CID for routing, unless they're in active collaboration with the server, are kind of stuck. Which might be intentional, but it seems awkward.

+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.

What I have in mind is the following:

  1. Assume that after encryption but before packet number encryption the packet is composed of encrypted payload (ccc...ccc), packet number (pp), and other header bytes (h)
    hhhhhhppppccccccc...ccc

After packet number encryption the "p" bytes will be encrypted (P). Some of the leading bytes in the ciphertext may also be re-encrypted (C):

    hhhhhhPPPPCCCCccc...ccc

This only works if the receiver can find out whether the "cipher text input" starts, without knowing the exact length of the packet encoding. At that point it only knows the position of the first packet number byte, and the length of the packet. I would like a way to specify the length of the "PN encryption" and the offset of the ciphertext sample without requiring the receiver to exactly know the packet number length.

My proposition is to set the "offset" value to MIN(pn_start + 8, packet_length-16), and to encrypt the bytes between "pn_start" and "offset".

@janaiyengar commented on this pull request.

High-level point: The goal of this PR is to replace PING+Data with new frames, to avoid overloaded semantics. I'd like to not fix migration bugs here, since I'd like to fix them in a separate PR (upcoming).

In draft-ietf-quic-transport.md:

> -new address.  Once a PONG frame containing the same payload is received, the
-address is considered to be valid.  The PONG frame can use any path on its
-return.  A PING frame containing 12 randomly generated {{?RFC4086}} octets is
-sufficient to ensure that it is easier to receive the packet than it is to guess
-the value correctly.
-
-If the PING frame is determined to be lost, a new PING frame SHOULD be
-generated.  This PING frame MUST include a new Data field that is similarly
-difficult to guess.
+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.  A PATH_CHALLENGE frame containing 12 randomly
+generated {{?RFC4086}} octets is sufficient to ensure that it is easier to

I don't have an opinion on size at all. I'll make it 8 bytes to avoid confusion... also because I don't think stateless operation is much of a benefit here.

Done.

This text is the same as previous, with PING+Data. I intend to change this in the PR that addresses other migration concerns, but not here.

The strategy that I'd like to suggest is to go back to the last best path. That said, this text is the same as it was previously with PING+Data and I'd like to not change migration behavior. I'd like to change this behavior but in a different PR that fixes migration. This PR simply replaces PING+Data / PONG with new frames.

Agreed, again not changing text here for what the draft currently states, since I'd like to simply get rid of PING+Data for now. This will change with fixing the rest of migration.

I think there's some concern that the connection ID ought to be self-describing. One concern, that I'm slightly sympathetic to, is that you'd still have to configure a co-operating middlebox to align with server policy, which may not be easy to do in all server deployments. I'd recommend leaving this particular question -- of removing the C bit -- out and discuss on an issue instead. The change to 17 byte CIDs and truncation seem quite independent of this question.

I think you meant to say Connection ID here: "This parameter is set to 0 if the transport parameter is omitted".

I'm not sure I like the rest of the phrasing, so how about "This parameter is set to 0 if the connection ID may be omitted in short header packets sent to this endpoint."

How does packet number leak information when there are packet number gaps? Sure, it needs to be fixed so the gaps are asymmetric, but that's basically fixable.

In terms of process, I don't think that this has consensus and I read the minutes as pretty clearly saying that we were going to form a design team to come up with some proposals, and then the WG was going to decide, so this PR seems premature. -- You are receiving this because you are subscribed to this thread.

In terms of process, I don't think that this has consensus and I read = the minutes as pretty clearly saying that we were going to form a design = team to come up with some proposals, and then the WG was going to decide,= so this PR seems premature.

The construction of a stateless reset requires that the server provide a packet number. It is probably using a connection ID that it used in the past, so packets can be correlated with previous packets. The difference in packet numbers is observable. A server has to pick a random packet number, which likely means a large gap. That might be used to distinguish a stateless reset.

Packet number encryption fixes that problem. I think that this will change if we decide to do that.
