B<quic_method> -+must remain valid for the lifetime of B<ctx> or B<ssl>. Calling this disables -+the SSL_OP_ENABLE_MIDDLEBOX_COMPAT option, which is not required for QUIC. -+ -+SSL_set_quic_transport_params() configures B<ssl> to send B<params> (of length -+B<params_len>) in the quic_transport_parameters extension in either the -+ClientHello or EncryptedExtensions handshake message. This extension will -+only be sent if the TLS version is at least 1.3, and for a server, only if -+the client sent the extension. The buffer pointed to by B<params> only need be -+valid for the duration of the call to this function. -+ -+SSL_get_peer_quic_transport_params() provides the caller with the value of the -+quic_transport_parameters extension sent by the peer. A pointer to the buffer -+containing the TransportParameters will be put in B<*out_params>, and its -+length in B<*out_params_len>. This buffer will be valid for the lifetime of the -+B<ssl>. If no params were received from the peer, B<*out_params_len> will be 0. -+ -+SSL_quic_max_handshake_flight_len() returns the maximum number of bytes -+that may be received at the given encryption level. This function should be -+used to limit buffering in the QUIC implementation. -+ -+See https://tools.ietf.org/html/draft-ietf-quic-transport-16#section-4.4. -+ -+SSL_quic_read_level() returns the current read encryption level. -+ -+SSL_quic_write_level() returns the current write encryption level. -+ -+SSL_provide_quic_data() provides data from QUIC at a particular encryption -+level B<level>. It is an error to call this function outside of the handshake -+or with an encryption level other than the current read level. It returns one -+on success and zero on error. -+ -+SSL_process_quic_post_handshake() processes any data that QUIC has provided -+after the handshake has completed. This includes NewSessionTicket messages -+sent by the server. -+ -+SSL_is_quic() indicates whether a connection uses QUIC. -+ -+=head1 NOTES -+ -+These APIs are implementations of BoringSSL's QUIC APIs. -+ -+QUIC acts as an underlying transport for the TLS 1.3 handshake. The following -+functions allow a QUIC implementation to serve as the underlying transport as -+described in draft-ietf-quic-tls. -+ -+When configured for QUIC, SSL_do_handshake() will drive the handshake as -+before, but it will not use the configured B<BIO>. It will call functions on -+B<SSL_QUIC_METHOD> to configure secrets and send data. If data is needed from -+the peer, it will return B<SSL_ERROR_WANT_READ>. When received, the caller -+should call SSL_provide_quic_data() and then SSL_do_handshake() to continue -+the handshake. After the handshake is complete, the caller should call -+SSL_provide_quic_data() for any post-handshake data, followed by -+SSL_process_quic_post_handshake() to process it. It is an error to call -+SSL_read()/SSL_read_ex() and SSL_write()/SSL_write_ex() in QUIC. -+ -+Note that secrets for an encryption level may be available to QUIC before the -+level is active in TLS. Callers should use SSL_quic_read_level() to determine -+the active read level for SSL_provide_quic_data(). SSL_do_handshake() will -+pass the active write level to add_handshake_data() when writing data. Callers -+can use SSL_quic_write_level() to query the active write level when -+generating their own errors. -+ -+See https://tools.ietf.org/html/draft-ietf-quic-tls-15#section-4.1 for more -+details. -+ -+To avoid DoS attacks, the QUIC implementation must limit the amount of data -+being queued up. The implementation can call -+SSL_quic_max_handshake_flight_len() to get the maximum buffer length at each -+encryption level. -+ -+draft-ietf-quic-tls defines a new TLS extension quic_transport_parameters -+used by QUIC for each endpoint to unilaterally declare its supported -+transport parameters. draft-ietf-quic-transport (section 7.4) defines the -+contents of that extension (a TransportParameters struct) and describes how -+to handle it and its semantic meaning. -+ -+OpenSSL handles this extension as an opaque byte string. The caller is -+responsible for serializing and parsing it. -+ -+=head2 OSSL_ENCRYPTION_LEVEL -+ -+B<OSSL_ENCRYPTION_LEVEL> (B<enum ssl_encryption_level_t>) represents the -+encryption levels: -+ -+=over 4 -+ -+=item ssl_encryption_initial -+ -+The initial encryption level that is used for client and server hellos. -+ -+=item ssl_encryption_early_data -+ -+The encryption level for early data. This is a write-level for the client -+and a read-level for the server. -+ -+=item ssl_encryption_handshake -+ -+The encryption level for the remainder of the handshake. -+ -+=item ssl_encryption_application -+ -+The encryption level for the application data. -+ -+=back -+ -+=head2 SSL_QUIC_METHOD -+ -+The B<SSL_QUIC_METHOD> (B<struct ssl_quic_method_st>) describes the -+QUIC methods. -+ -+ struct ssl_quic_method_st { -+ int (*set_encryption_secrets)(SSL *ssl, OSSL_ENCRYPTION_LEVEL level, -+ const uint8_t *read_secret, -+ const uint8_t *write_secret, size_t secret_len); -+ int (*add_handshake_data)(SSL *ssl, OSSL_ENCRYPTION_LEVEL level, -+ const uint8_t *data, size_t len); -+ int (*flush_flight)(SSL *ssl); -+ int (*send_alert)(SSL *ssl, enum ssl_encryption_level_t level, uint8_t alert); -+ }; -+ typedef struct ssl_quic_method_st SSL_QUIC_METHOD; -+ -+set_encryption_secrets() configures the read and write secrets for the given -+encryption level. This function will always be called before an encryption -+level other than B<ssl_encryption_initial> is used. Note, however, that -+secrets for a level may be configured before TLS is ready to send or accept -+data at that level. -+ -+When reading packets at a given level, the QUIC implementation must send -+ACKs at the same level, so this function provides read and write secrets -+together. The exception is B<ssl_encryption_early_data>, where secrets are -+only available in the client to server direction. The other secret will be -+NULL. The server acknowledges such data at B<ssl_encryption_application>, -+which will be configured in the same SSL_do_handshake() call. -+ -+This function should use SSL_get_current_cipher() to determine the TLS -+cipher suite. -+ -+add_handshake_data() adds handshake data to the current flight at the given -+encryption level. It returns one on success and zero on error. -+ -+OpenSSL will pack data from a single encryption level together, but a -+single handshake flight may include multiple encryption levels. Callers -+should defer writing data to the network until flush_flight() to better -+pack QUIC packets into transport datagrams. -+ -+flush_flight() is called when the current flight is complete and should be -+written to the transport. Note a flight may contain data at several -+encryption levels. -+ -+send_alert() sends a fatal alert at the specified encryption level. -+ -+All QUIC methods return 1 on success and 0 on error. -+ -+=head1 RETURN VALUES -+ -+SSL_CTX_set_quic_method(), -+SSL_set_quic_method(), -+SSL_set_quic_transport_params(), and -+SSL_process_quic_post_handshake() -+return 1 on success, and 0 on error. -+ -+SSL_quic_read_level() and SSL_quic_write_level() return the current -+encryption level as B<OSSL_ENCRYPTION_LEVEL> (B<enum ssl_encryption_level_t>). -+ -+SSL_quic_max_handshake_flight_len() returns the maximum length of a flight -+for a given encryption level. -+ -+SSL_is_quic() returns 1 if QUIC is being used, 0 if not. -+ -+=head1 SEE ALSO -+ -+L<ssl(7)>, L<SSL_CIPHER_get_prf_nid(3)>, L<SSL_do_handshake(3)> -+ -+=head1 HISTORY -+ -+These functions were added in OpenSSL 3.0.0. -+ -+=head1 COPYRIGHT -+ -+Copyright 2019 The OpenSSL Project Authors.

Once created, -a `QuicSocket` is associated with a local network address and IP port and can -act as both a QUIC client and server simultaneously.

Once the - `QuicSession` enters the `Ready` state, it may be used to exchange - application data using `QuicStream` instances. -* `Closed` - Entered as soon as the `QuicSession` connection has been - terminated. - -New instances of `QuicClientSession` are created using the `connect()` -function on a `QuicSocket` as in the example below: - -```js -const { createQuicSocket } = require('net'); - -// Create a QuicSocket associated with localhost and port 1234 -const socket = createQuicSocket({ endpoint: { port: 1234 } }); - -(async function() { - const client = await socket.connect({ - address: 'example.com', - port: 4567, - alpn: 'foo' - }); -})(); -``` - -As soon as the `QuicClientSession` is created, the `address` provided in -the connect options will be resolved to an IP address (if necessary), and -the TLS 1.3 handshake will begin.

Every `QuicSession` instance has an ALPN identifier that *must* be -specified in either the `connect()` or `listen()` options. ALPN identifiers that -are known to Node.js (such as the ALPN identifier for HTTP/3) will alter how the -`QuicSession` and `QuicStream` objects operate internally, but the QUIC -implementation for Node.js has been designed to allow any ALPN to be specified -and used. - -### QuicStream - -Once a `QuicSession` transitions to the `Ready` state, `QuicStream` instances -may be created and used to exchange application data. On a general level, all -`QuicStream` instances are simply Node.js Duplex Streams that allow -bidirectional data flow between the QUIC client and server. However, the -application protocol negotiated for the `QuicSession` may alter the semantics -and operation of a `QuicStream` associated with the session. Specifically, -some features of the `QuicStream` (e.g. headers) are enabled only if the -application protocol selected is known by Node.js to support those features. - -Once the `QuicSession` is ready, a `QuicStream` may be created by either the -client or server, and may be unidirectional or bidirectional. - -The `openStream()` method is used to create a new `QuicStream`: - -```js -// Create a new bidirectional stream -async function createStreams(session) { - const stream1 = await session.openStream(); - - // Create a new unidirectional stream - const stream2 = await session.openStream({ halfOpen: true }); -} -``` - -As suggested by the names, a bidirectional stream allows data to be sent on -a stream in both directions, by both client and server, regardless of which -peer opened the stream. A unidirectional stream can be written to only by the -QuicSession that opened it. - -The `'stream'` event is emitted by the `QuicSession` when a new `QuicStream` -has been initiated by the connected peer: - -```js -session.on('stream', (stream) => { - if (stream.bidirectional) { - stream.write('Hello World'); - stream.end(); - } - stream.on('data', console.log); - stream.on('end', () => {}); -}); -``` - -#### QuicStream headers - -Some QUIC application protocols (like HTTP/3) use headers. - -There are four kinds of headers that the Node.js QUIC implementation -is capable of handling dependent entirely on known application protocol -support: - -* Informational Headers -* Initial Headers -* Trailing Headers -* Push Headers - -These categories correlate exactly with the equivalent HTTP -concepts: - -* Informational Headers: Any response headers transmitted within - a block of headers using a `1xx` status code. -* Initial Headers: HTTP request or response headers -* Trailing Headers: A block of headers that follow the body of a - request or response. -* Push Promise Headers: A block of headers included in a promised - push stream. - -If headers are supported by the application protocol in use for -a given `QuicSession`, the `'initialHeaders'`, `'informationalHeaders'`, -and `'trailingHeaders'` events will be emitted by the `QuicStream` -object when headers are received; and the `submitInformationalHeaders()`, -`submitInitialHeaders()`, and `submitTrailingHeaders()` methods can be -used to send headers. - -## QUIC and HTTP/3 - -HTTP/3 is an application layer protocol that uses QUIC as the transport. - -TBD - -## QUIC JavaScript API - -### `net.createQuicSocket([options])` -<!-- YAML -added: v15.0.0 ---> - -* `options` {Object} - * `client` {Object} A default configuration for QUIC client sessions created - using `quicsocket.connect()`. - * `disableStatelessReset` {boolean} When `true` the `QuicSocket` will not - send stateless resets. **Default**: `false`. - * `endpoint` {Object} An object describing the local address to bind to. - * `address` {string} The local address to bind to.

However, it is possible to pass a custom `lookup` -function as an option in several places throughout the QUIC API: - -* `net.createQuicSocket()` -* `quicsocket.addEndpoint()` -* `quicsocket.connect()` -* `quicsocket.listen()` - -The custom `lookup` function must return a `Promise` that is -resolved once the lookup is complete. It will be invoked with -two arguments: - -* `address` {string|undefined} The host name to resolve, or - `undefined` if no host name was provided. -* `family` {number} One of `4` or `6`, identifying either - IPv4 or IPv6. - -```js -async function myCustomLookup(address, type) { - // TODO(@jasnell): Make this example more useful - return resolveTheAddressSomehow(address, type); -} -``` - -### Online Certificate Status Protocol (OCSP) - -The QUIC implementation supports use of OCSP during the TLS 1.3 handshake -of a new QUIC session. - -#### Requests - -A `QuicServerSession` can receive and process OCSP requests by setting the -`ocspHandler` option in the `quicsocket.listen()` function.

This is accomplished using -the `clientHelloHandler` option when calling `quicsocket.listen()`. - -The value of `clientHelloHandler` is an async function that is called at the -start of a new `QuicServerSession`. It is invoked with three arguments: - -* `alpn` {string} The ALPN protocol identifier specified by the client. -* `servername` {string} The SNI server name specified by the client. -* `ciphers` {string[]} The array of TLS 1.3 ciphers specified by the client. - -The `clientHelloHandler` can return a new {tls.SecureContext} object that will -be used to continue the TLS handshake.
