README

A QUIC implementation in pure Go (Scheduler)

PkgGoDev Code Coverage

quic-go is an implementation of the QUIC protocol, RFC 9000 protocol in Go. In addition to RFC 9000, it currently implements the IETF QUIC draft-29. Support for draft-29 will eventually be dropped, as it is phased out of the ecosystem.

Guides

We currently support Go 1.18.x and Go 1.19.1.

Running tests:

go test ./...
QUIC without HTTP/3

Take a look at this echo example.

Usage

As a server

See the example server. Starting a QUIC server is very similar to the standard lib http in go:

http.Handle("/", http.FileServer(http.Dir(wwwDir)))
http3.ListenAndServeQUIC("localhost:4242", "/path/to/cert/chain.pem", "/path/to/privkey.pem", nil)
As a client

See the example client. Use a http3.RoundTripper as a Transport in a http.Client.

http.Client{
  Transport: &http3.RoundTripper{},
}

Config contains all configuration data needed for a QUIC server or client.

func (*Config) Clone

func (c *Config) Clone() *Config

Clone clones a Config

type Configuration

type Configuration struct {
	Scheduler_name string
	Weight         []float64
	Penalty        []float64
}

type ConnectionState

type ConnectionState struct {
	TLS               handshake.ConnectionState
	SupportsDatagrams bool
}

ConnectionState records basic details about a QUIC connection

type EarlyListener

type EarlyListener interface {
	// Close the server. All active sessions will be closed.
	Close() error
	// Addr returns the local network addr that the server is listening on.
	Addr() net.Addr
	// Accept returns new early sessions. It should be called in a loop.
	Accept(context.Context) (EarlySession, error)
}

An EarlyListener listens for incoming QUIC connections, and returns them before the handshake completes.

func ListenAddrEarly

func ListenAddrEarly(addr string, tlsConf *tls.Config, config *Config) (EarlyListener, error)

ListenAddrEarly works like ListenAddr, but it returns sessions before the handshake completes.

func ListenEarly

func ListenEarly(conn net.PacketConn, tlsConf *tls.Config, config *Config) (EarlyListener, error)

ListenEarly works like Listen, but it returns sessions before the handshake completes.

type EarlySession

type EarlySession interface {
	Session

	// HandshakeComplete blocks until the handshake completes (or fails).
	// Data sent before completion of the handshake is encrypted with 1-RTT keys.
	// Note that the client's identity hasn't been verified yet.
	HandshakeComplete() context.Context

	NextSession() Session
}

An EarlySession is a session that is handshaking. Data sent during the handshake is encrypted using the forward secure keys. When using client certificates, the client's identity is only verified after completion of the handshake.

func DialAddrEarly

func DialAddrEarly(
	addr string,
	tlsConf *tls.Config,
	config *Config,
) (EarlySession, error)

DialAddrEarly establishes a new 0-RTT QUIC connection to a server. It uses a new UDP connection and closes this connection when the QUIC session is closed. The hostname for SNI is taken from the given address. The tls.Config.CipherSuites allows setting of TLS 1.3 cipher suites.

func DialAddrEarlyContext

func DialAddrEarlyContext(
	ctx context.Context,
	addr string,
	tlsConf *tls.Config,
	config *Config,
) (EarlySession, error)

DialAddrEarlyContext establishes a new 0-RTT QUIC connection to a server using provided context. See DialAddrEarly for details

func DialEarly

func DialEarly(
	pconn net.PacketConn,
	remoteAddr net.Addr,
	host string,
	tlsConf *tls.Config,
	config *Config,
) (EarlySession, error)

DialEarly establishes a new 0-RTT QUIC connection to a server using a net.PacketConn. The same PacketConn can be used for multiple calls to Dial and Listen, QUIC connection IDs are used for demultiplexing the different connections. The host parameter is used for SNI. The tls.Config must define an application protocol (using NextProtos).

func DialEarlyContext

func DialEarlyContext(
	ctx context.Context,
	pconn net.PacketConn,
	remoteAddr net.Addr,
	host string,
	tlsConf *tls.Config,
	config *Config,
) (EarlySession, error)

type Listener interface {
	// Close the server. All active sessions will be closed.
	Close() error
	// Addr returns the local network addr that the server is listening on.
	Addr() net.Addr
	// Accept returns new sessions. It should be called in a loop.
	Accept(context.Context) (Session, error)
}

A Listener for incoming QUIC connections

func Listen

func Listen(conn net.PacketConn, tlsConf *tls.Config, config *Config) (Listener, error)

Listen listens for QUIC connections on a given net.PacketConn. If the PacketConn satisfies the OOBCapablePacketConn interface (as a net.UDPConn does), ECN and packet info support will be enabled. In this case, ReadMsgUDP and WriteMsgUDP will be used instead of ReadFrom and WriteTo to read/write packets. A single net.PacketConn only be used for a single call to Listen. The PacketConn can be used for simultaneous calls to Dial. QUIC connection IDs are used for demultiplexing the different connections. The tls.Config must not be nil and must contain a certificate configuration. The tls.Config.CipherSuites allows setting of TLS 1.3 cipher suites. Furthermore, it must define an application control (using NextProtos). The quic.Config may be nil, in that case the default values will be used.

func ListenAddr

func ListenAddr(addr string, tlsConf *tls.Config, config *Config) (Listener, error)

ListenAddr creates a QUIC server listening on a given address. The tls.Config must not be nil and must contain a certificate configuration. The quic.Config may be nil, in that case the default values will be used.

type OOBCapablePacketConn

type OOBCapablePacketConn interface {
	net.PacketConn
	SyscallConn() (syscall.RawConn, error)
	ReadMsgUDP(b, oob []byte) (n, oobn, flags int, addr *net.UDPAddr, err error)
	WriteMsgUDP(b, oob []byte, addr *net.UDPAddr) (n, oobn int, err error)
}

If the PacketConn passed to Dial or Listen satisfies this interface, quic-goV2 will read the ECN bits from the IP header. In this case, ReadMsgUDP() will be used instead of ReadFrom() to read packets.

type ReceiveStream

type ReceiveStream interface {
	// StreamID returns the stream ID.
	StreamID() StreamID
	// Read reads data from the stream.
	// Read can be made to time out and return a net.Error with Timeout() == true
	// after a fixed time limit; see SetDeadline and SetReadDeadline.
	// If the stream was canceled by the peer, the error implements the StreamError
	// interface, and Canceled() == true.
	// If the session was closed due to a timeout, the error satisfies
	// the net.Error interface, and Timeout() will be true.
	io.Reader
	// CancelRead aborts receiving on this stream.
	// It will ask the peer to stop transmitting stream data.
	// Read will unblock immediately, and future Read calls will fail.
	// When called multiple times or after reading the io.EOF it is a no-op.
	CancelRead(StreamErrorCode)

	SetReadDeadline(t time.Time) error
}

A ReceiveStream is a unidirectional Receive Stream.

type SendStream

type SendStream interface {
	// StreamID returns the stream ID.
	StreamID() StreamID
	// Write writes data to the stream.
	// Write can be made to time out and return a net.Error with Timeout() == true
	// after a fixed time limit; see SetDeadline and SetWriteDeadline.
	// If the stream was canceled by the peer, the error implements the StreamError
	// interface, and Canceled() == true.
	// If the session was closed due to a timeout, the error satisfies
	// the net.Error interface, and Timeout() will be true.
	io.Writer
	// Close closes the write-direction of the stream.
	// Future calls to Write are not permitted after calling Close.
	// It must not be called concurrently with Write.
	// It must not be called after calling CancelWrite.
	io.Closer
	// CancelWrite aborts sending on this stream.
	// Data already written, but not yet delivered to the peer is not guaranteed to be delivered reliably.
	// Write will unblock immediately, and future calls to Write will fail.
	// When called multiple times or after closing the stream it is a no-op.
	CancelWrite(StreamErrorCode)
	// The Context is canceled as soon as the write-side of the stream is closed.
	// This happens when Close() or CancelWrite() is called, or when the peer
	// cancels the read-side of their stream.
	// Warning: This API should not be considered stable and might change soon.
	Context() context.Context
	// SetWriteDeadline sets the deadline for future Write calls
	// and any currently-blocked Write call.
	// Even if write times out, it may return n > 0, indicating that
	// some data was successfully written.
	// A zero value for t means Write will not time out.
	SetWriteDeadline(t time.Time) error
	// AdvancedOutgoingStreamManagement defines extra methods to better control outgoing streams
	AdvancedOutgoingStreamManagement
}

A SendStream is a unidirectional Send Stream.

type Session

type Session interface {
	// AcceptStream returns the next stream opened by the peer, blocking until one is available.
	// If the session was closed due to a timeout, the error satisfies
	// the net.Error interface, and Timeout() will be true.
	AcceptStream(context.Context) (Stream, error)
	// AcceptUniStream returns the next unidirectional stream opened by the peer, blocking until one is available.
	// If the session was closed due to a timeout, the error satisfies
	// the net.Error interface, and Timeout() will be true.
	AcceptUniStream(context.Context) (ReceiveStream, error)
	// OpenStream opens a new bidirectional QUIC stream.
	// There is no signaling to the peer about new streams:
	// The peer can only accept the stream after data has been sent on the stream.
	// If the error is non-nil, it satisfies the net.Error interface.
	// When reaching the peer's stream limit, err.Temporary() will be true.
	// If the session was closed due to a timeout, Timeout() will be true.

}

A Session is a QUIC connection between two peers. Calls to the session (and to streams) can return the following types of errors: * ApplicationError: for errors triggered by the application running on top of QUIC * TransportError: for errors triggered by the QUIC transport (in many cases a misbehaving peer) * IdleTimeoutError: when the peer goes away unexpectedly (this is a net.Error timeout error) * HandshakeTimeoutError: when the cryptographic handshake takes too long (this is a net.Error timeout error) * StatelessResetError: when we receive a stateless reset (this is a net.Error temporary error) * VersionNegotiationError: returned by the client, when there's no version overlap between the peers

) (Session, error)

Dial establishes a new QUIC connection to a server using a net.PacketConn. If the PacketConn satisfies the OOBCapablePacketConn interface (as a net.UDPConn does), ECN and packet info support will be enabled. In this case, ReadMsgUDP and WriteMsgUDP will be used instead of ReadFrom and WriteTo to read/write packets. The same PacketConn can be used for multiple calls to Dial and Listen, QUIC connection IDs are used for demultiplexing the different connections. The host parameter is used for SNI. The tls.Config must define an application protocol (using NextProtos).
