Well done!

I believe we would now as well need to send the capsule-protocol HTTP header on the EXTENDED_CONNECT stream.

https://www.rfc-editor.org/rfc/rfc9297#section-3.4

As far as I understand, this allows a user to send a capsule to us.

In addition, could you add an end-to-end test showcasing how a neqo-client and a neqo-server (neither supporting QUIC datagrams) will exchange (proxy) UDP datagrams using connect-udp and HTTP DATAGRAM capsules? session_lifecycle in the file below should be a good example.

@WaterWhisperer let me know if you need any help with the above. I saw you resolved all comments but didn't make any changes yet.

@mxinden Thanks for your attention! Yeah, I've resolved all the comments. However, when I was adding

an end-to-end test showing how a neqo-client and a neqo-server (neither supporting QUIC datagrams) will exchange (proxy) UDP datagrams using connect-udp and HTTP DATAGRAM capsules

, I found the test wasn't working. I then realized that my implementation is incomplete

Currently, my changes support:

Decoding HTTP DATAGRAM Capsules from the stream (receiving side works)
The capsule-protocol header in responses

However, the sending side still only uses QUIC datagrams. I haven't implemented sending via HTTP DATAGRAM Capsules on the stream yet. I'm trying my best on completing this to fully meet the RFC 9297 requirements.

I'll update the PR once I have a working end-to-end test. Thanks again for your follow-up!

mxinden · 2025-11-13T12:03:42Z

Great work. I appreciate the help!

WaterWhisperer · 2025-11-14T07:40:48Z

I've encountered a problem: I'm trying to send a Capsule using SendMessage::send_data(), but this method automatically wraps it in a DATA frame.
The final data structure becomes [DATA frame][Capsule], and the receiving end's FrameReader will parse the DATA frame and treat the contents of the Capsule as the frame payload.
My solution was to bypass the HTTP/3 framing layer and read/write raw bytes directly on the stream, manually handling Capsule encoding/decoding. However, this made the connect_udp_frame dead_code, which intuitively tells me is wrong, but I can't think of a better way.

@mxinden is busy at the moment, so please don't take his silence as us having lost interest here. Will take us a few more days to respond. Thanks again for your help!

mxinden · 2025-11-26T20:07:24Z

@WaterWhisperer sorry for the delay here. Good catch. I didn't think of this before.

Instead of using SendMessage::send_data, how about using <SendMessage as SendStream>::send_data_atomic?

neqo/neqo-http3/src/send_message.rs

Lines 298 to 306 in c2caaa2

    
           fn send_data_atomic(&mut self, conn: &mut Connection, buf: &[u8], now: Instant) -> Res<()> { 
        
               let data_frame = HFrame::Data { 
        
                   len: buf.len() as u64, 
        
               }; 
        
               self.stream.encode_with(|e| data_frame.encode(e)); 
        
               self.stream.buffer(buf); 
        
               _ = self.stream.send_buffer(conn, now)?; 
        
               Ok(()) 
        
           }

Our WebTransport implementation has the same use-case, namely to send its custom-framed control messages. Here is how WebTransport sends a closing frame:

neqo/neqo-http3/src/features/extended_connect/session.rs

Lines 360 to 363 in c2caaa2

    
           if let Some(close_frame) = self.protocol.close_frame(error, message) { 
        
               self.control_stream_send 
        
                   .send_data_atomic(conn, close_frame.as_ref(), now)?; 
        
           }

Does that help @WaterWhisperer?

I don't think it is safe to fallback to capsules on all errors. I think we should only send capsules, if the remote did not negotiate the QUIC datagram extension, or if the remote set the max datagram size to 0.

https://www.rfc-editor.org/rfc/rfc9221.html#section-3

Note also this paragraph from the connect-udp draft:

If a UDP proxy is using QUIC DATAGRAM frames and it receives a UDP payload from the target that will not fit inside a QUIC DATAGRAM frame, the UDP proxy SHOULD NOT send the UDP payload in a DATAGRAM capsule, as that defeats the end-to-end unreliability characteristic that methods such as Datagram Packetization Layer PMTU Discovery (DPLPMTUD) depend on [DPLPMTUD].

https://www.rfc-editor.org/rfc/rfc9298.html#section-6.1

You might have to expose the remote_datagram_size function to neqo-http3 in order to check here whether it is 0 or not.

neqo/neqo-transport/src/quic_datagrams.rs

Lines 93 to 95 in c2caaa2

+        let capsule = Capsule::Datagram {
+            payload: Bytes::from(buf.to_vec()),


Unnecessary allocation: buf.to_vec() creates a copy of the buffer. Since Bytes can be constructed from a slice reference in many contexts, consider if this copy is necessary or if Bytes::copy_from_slice(buf) would be more idiomatic to make the copy explicit.

Suggested change

payload: Bytes::from(buf.to_vec()),

payload: Bytes::copy_from_slice(buf),

the Bytes here is not the crate Bytes so it doesn't have copy_from_slice method, do we need to create a copy_from_slice method for Bytes in the codebase?

Unnecessary allocation: payload.to_vec() creates a copy when payload is already a slice. Since Bytes::from() can take a Vec<u8> directly, this creates a redundant allocation. Consider using Bytes::copy_from_slice(payload) to make the copy operation explicit and idiomatic.

Suggested change
