connectivity between mvfst and quic-go

[giantpoplar]

Hi,

We use quic-go to start a server and want to use mvfst work as a client. The quic-go server is started as follows:

listener, err := quic.ListenAddr("0.0.0.0:9000", generateTLSConfig(), nil)
func generateTLSConfig() *tls.Config {
	key, err := rsa.GenerateKey(rand.Reader, 1024)
	if err != nil {
		panic(err)
	}
	template := x509.Certificate{SerialNumber: big.NewInt(1)}
	certDER, err := x509.CreateCertificate(rand.Reader, &template, &template, &key.PublicKey, key)
	if err != nil {
		panic(err)
	}
	keyPEM := pem.EncodeToMemory(&pem.Block{Type: "RSA PRIVATE KEY", Bytes: x509.MarshalPKCS1PrivateKey(key)})
	certPEM := pem.EncodeToMemory(&pem.Block{Type: "CERTIFICATE", Bytes: certDER})

	tlsCert, err := tls.X509KeyPair(certPEM, keyPEM)
	if err != nil {
		panic(err)
	}
	return &tls.Config{
		Certificates: []tls.Certificate{tlsCert},
		NextProtos:   []string{"quic-freetalk"},
	}
}

Then we run the mvfst EchoClient as follows:

./_build/build/quic/samples/echo -mode=client -host=127.0.0.1 -port=9000

However, the following error info is printed:

I0326 15:20:23.815001 147673088 EchoClient.h:130] EchoClient connecting to 127.0.0.1:9000
E0326 15:20:23.816485 147673088 EchoClient.h:85] EchoClient error: Connection abandoned

So how can we config mvfst to establish a connection to quic-go? I can do this by using pure golang client:

tlsConf := &tls.Config{
  InsecureSkipVerify: true,
  NextProtos:         []string{"quic-freetalk"},
}
session, err := quic.DialAddr("127.0.0.1:9000", tlsConf, nil)

How can we adapt this to mvfst?

Best regards

Can you run it with "-v=4" and give us the log? Thanks.

Also if you rebase past eaf764b, we can see if this is write error or version negotiation. Those are the 2 possibilities of connection abandon i'm aware of.

I'm closing this due to lack of activity for 2 weeks. Feel free to open if you have more logs you can collect as i stated before. Thanks.
