Set to `false` to disable early data support. + #### `sessionOptions.groups` + +* Type: {string} +* **Default:** `'drop-oldest'` + +Controls which datagram to drop when the pending datagram queue +(sized by [`session.maxPendingDatagrams`][]) is full. Must be one of +`'drop-oldest'` (discard the oldest queued datagram to make room) or +`'drop-newest'` (reject the incoming datagram). Dropped datagrams are +reported as lost via the `ondatagramstatus` callback. + +This option is immutable after session creation. + +#### `sessionOptions.maxDatagramSendAttempts` + +* Type: {number} +* **Default:** `5` + +The maximum number of `SendPendingData` cycles a datagram can survive +without being sent before it is abandoned. When a datagram cannot be +sent due to congestion control or packet size constraints, it remains +in the queue and the attempt counter increments. Once the limit is +reached, the datagram is dropped and reported as `'abandoned'` via the +`ondatagramstatus` callback. Valid range: `1` to `255`. + +#### `sessionOptions.drainingPeriodMultiplier` + + + +* Type: {number} +* **Default:** `3` + +A multiplier applied to the Probe Timeout (PTO) to compute the draining +period duration after receiving a `CONNECTION_CLOSE` frame from the peer. +RFC 9000 Section 10.2 requires the draining period to persist for at least +three times the current PTO. The valid range is `3` to `255`. Values below +`3` are clamped to `3`. + #### `sessionOptions.handshakeTimeout` + +* Type: {bigint|number} +* **Default:** `0` (disabled) + +Specifies the keep-alive timeout in milliseconds. When set to a non-zero +value, PING frames will be sent automatically to keep the connection alive +before the idle timeout fires. The value should be less than the effective +idle timeout (`maxIdleTimeout` transport parameter) to be useful. + #### `sessionOptions.servername` (client only) + +* Type: {ArrayBufferView} + +An opaque address validation token previously received from the server +via the [`session.onnewtoken`][] callback. Providing a valid token on +reconnection allows the client to skip the server's address validation, +reducing handshake latency. + #### `sessionOptions.transportParams` + +* Type: {boolean} **Default:** `true` + +If `true`, the peer certificate is verified against the list of supplied CAs. +An error is emitted if verification fails; the error can be inspected via +the `validationErrorReason` and `validationErrorCode` fields in the +handshake callback. If `false`, peer certificate verification errors are +ignored. + +#### `sessionOptions.reuseEndpoint` + + + +* Type: {boolean} +* Default: `true` + +When `true` (the default), `connect()` will attempt to reuse an existing +endpoint rather than creating a new one for each session. This provides +connection pooling behavior — multiple sessions can share a single UDP +socket. The reuse logic will not return an endpoint that is listening on +the same address as the connect target (to prevent CID routing conflicts). + +Set to `false` to force creation of a new endpoint for the session.

Each Session wraps an `ngtcp2_conn` and delegates +protocol-specific behavior to an **Application** (selected by ALPN +negotiation). Sessions contain **Streams** — bidirectional or unidirectional +data channels that carry application data. + +## File Map + +### Foundation + +| File | Purpose | +| ------------- | ------------------------------------------------------------------ | +| `guard.h` | OpenSSL QUIC guard macro | +| `defs.h` | Core enums, typedefs, constants, macros | +| `arena.h` | Block-based arena allocator (header-only template) | +| `data.h/cc` | `Path`, `PathStorage`, `Store`, `QuicError` | +| `cid.h/cc` | `CID` — Connection ID with hash, factory, map alias | +| `tokens.h/cc` | `TokenSecret`, `StatelessResetToken`, `RetryToken`, `RegularToken` | + +### Security + +| File | Purpose | +| -------------------- | ----------------------------------------------------------- | +| `tlscontext.h/cc` | `TLSContext`, `TLSSession` — OpenSSL integration, SNI, ALPN | +| `sessionticket.h/cc` | `SessionTicket` — TLS 1.3 session resumption and 0-RTT | + +### Core + +| File | Purpose | +| ------------------ | ------------------------------------------------------------ | +| `endpoint.h/cc` | `Endpoint` — UDP binding, packet dispatch, retry/validation | +| `session.h/cc` | `Session` — QUIC connection state machine (\~3,500 lines) | +| `streams.h/cc` | `Stream`, `Outbound`, `PendingStream` — data flow | +| `application.h/cc` | `Session::Application` base + `DefaultApplication` | +| `http3.h/cc` | `Http3ApplicationImpl` — nghttp3 integration (\~1,400 lines) | + +### Infrastructure + +| File | Purpose | +| ----------------------- | ------------------------------------------------------------- | +| `bindingdata.h/cc` | `BindingData` — JS binding state, callback scopes, allocators | +| `session_manager.h/cc` | `SessionManager` — per-Realm CID→Session routing | +| `transportparams.h/cc` | `TransportParams` — QUIC transport parameter encoding | +| `packet.h/cc` | `Packet` — arena-allocated outbound packets | +| `preferredaddress.h/cc` | `PreferredAddress` — server preferred address helper | +| `quic.cc` | Module entry point (binding registration) | + +## Key Design Patterns + +### SendPendingDataScope (RAII Send Coalescing) + +Every entry point that may generate outbound data creates a +`SendPendingDataScope`. Scopes nest — an internal depth counter ensures +`Application::SendPendingData()` is called exactly once, when the outermost +scope exits: + +```cpp +{ + SendPendingDataScope outer(session); // depth 1 + { + SendPendingDataScope inner(session); // depth 2 + // ... generate data ... + } // depth 1 — no send yet +} // depth 0 — SendPendingData() fires +``` + +This is used in `Session::Receive`, `Endpoint::Connect`, `Session::Close`, +`Session::ResumeStream`, and all stream write operations. + +### NgTcp2CallbackScope / NgHttp3CallbackScope + +Per-session RAII guards that prevent re-entrant calls into ngtcp2/nghttp3. +While active, `can_send_packets()` returns false, blocking the send loop. +If `Destroy()` is called during a callback (e.g., via JS `MakeCallback`), +destruction is deferred until the scope exits, preventing use-after-free. + +### Bob Protocol (Pull-Based Streaming) + +Data flows through the stack using the **bob** (Bytes-Over-Buffers) pull +protocol defined in `src/node_bob.h`. The consumer calls `Pull()` on a +source, which responds with one of four status codes: + +| Status | Meaning | +| --------------------- | ---------------------------------------------------------------- | +| `STATUS_EOS` (0) | End of stream — no more data | +| `STATUS_CONTINUE` (1) | Data delivered; pull again | +| `STATUS_BLOCK` (2) | No data now; try later | +| `STATUS_WAIT` (3) | Async — source will invoke the `next` callback when data arrives | + +The `Done` callback passed with each pull signals that the consumer is +finished with the buffer memory, enabling zero-copy transfer. + +### Three-Phase Buffer Lifecycle + +Data in `Stream::Outbound` moves through three states: + +```text +Pulled (uncommitted) → Committed (in-flight) → Acknowledged (freed) +``` + +* **Uncommitted**: Read from the DataQueue but not yet accepted by ngtcp2 +* **Committed**: Accepted into a QUIC packet by `ngtcp2_conn_writev_stream` +* **Acknowledged**: Peer ACKed the data; buffer memory is released + +Separate cursors on each buffer entry track progression. This allows ngtcp2 +to retry uncommitted data (e.g., after pacing/congestion clears) without +re-reading from the source. + +### Application Abstraction + +`Session::Application` is a virtual interface that the Session delegates +ALPN-specific behavior to. Two implementations exist: + +* **`DefaultApplication`** (`application.cc`): Used for non-HTTP/3 ALPN + protocols. Maintains its own stream scheduling queue. Streams are scheduled + via an intrusive linked list. + +* **`Http3ApplicationImpl`** (`http3.cc`): Used when ALPN negotiates `h3`. + Wraps `nghttp3_conn` for HTTP/3 framing, header compression (QPACK), + server push, and stream prioritization. Manages unidirectional control + streams internally. + +The Application is selected during ALPN negotiation — immediately for +clients (ALPN known upfront), during the `OnSelectAlpn` TLS callback for +servers. + +### Thread-Local Allocator + +Both ngtcp2 and nghttp3 require custom allocators (`ngtcp2_mem`, +`nghttp3_mem`). These allocator structs must outlive every object they +create. Some nghttp3 objects (notably `rcbuf`s backing V8 external strings) +can survive past `BindingData` destruction during isolate teardown. + +The solution uses `thread_local` storage: + +```cpp +struct QuicAllocState { + BindingData* binding = nullptr; // Nulled in ~BindingData + ngtcp2_mem ngtcp2; + nghttp3_mem nghttp3; +}; +thread_local QuicAllocState quic_alloc_state; +``` + +Each allocation prepends its size before the returned pointer. This allows +`free` and `realloc` to report correct sizes for memory tracking. When +`binding` is null (after `BindingData` destruction), allocations still +succeed but memory tracking is silently skipped. + +## Session Lifecycle + +### Creation + +**Client**: `Endpoint::Connect()` builds a `Session::Config` with +`Side::CLIENT`, creates a `TLSContext`, and calls `Session::Create()` → +`ngtcp2_conn_client_new()`. The Application is selected immediately. + +**Server**: `Endpoint::Receive()` processes an Initial packet through +address validation (retry tokens, LRU cache), then calls `Session::Create()` +→ `ngtcp2_conn_server_new()`. The Application is selected later, during ALPN +negotiation in the TLS handshake. + +### The Receive Path + +```text +uv_udp_recv_cb + → Endpoint::Receive() + → FindSession(dcid) // CID lookup across endpoints + ├── Found → Session::Receive() + └── Not found: + ├── Stateless reset? → process + ├── Short header? → SendStatelessReset() + └── Long header? → acceptInitialPacket() + ├── ngtcp2_accept() + ├── Address validation (retry tokens, LRU) + └── Session::Create() + +Session::Receive() + → SendPendingDataScope // will send after processing + → NgTcp2CallbackScope // re-entrancy guard + → ngtcp2_conn_read_pkt() // decrypt, process frames + triggers callbacks: + ├── recv_stream_data → Application::ReceiveStreamData() + ├── stream_open → Application::ReceiveStreamOpen() + ├── acked_stream_data → Application::AcknowledgeStreamData() + ├── handshake_completed → Session::HandshakeCompleted() + └── ... others + → Application::PostReceive() // deferred operations (e.g., GOAWAY) +``` + +### The Send Loop + +```text +SendPendingDataScope::~SendPendingDataScope() + → Application::SendPendingData() + Loop (up to max_packet_count): + ├── GetStreamData() // pull data from next stream + │ └── stream->Pull() // bob pull from Outbound→DataQueue + ├── WriteVStream() // ngtcp2_conn_writev_stream() + │ encrypts, frames, paces + ├── if ndatalen > 0: StreamCommit() + │ stream->Commit(datalen, fin) + ├── if nwrite > 0: Send() // uv_udp_send() + ├── if WRITE_MORE: continue // room for more in this packet + ├── if STREAM_DATA_BLOCKED: // flow control + │ StreamDataBlocked(), continue + └── if nwrite == 0: // pacing/congestion + ResumeStream() if data pending, return + On exit: UpdateTimer(), UpdateDataStats() +``` + +When `nwrite == 0` and the stream had unsent data (payload or FIN), the +stream is re-scheduled via `Application::ResumeStream()` so the next +timer-triggered `SendPendingData` retries it. + +### Close Methods + +| Method | Behavior | +| ------------ | ----------------------------------------------------------- | +| **DEFAULT** | Destroys all streams, sends CONNECTION\_CLOSE, emits to JS | +| **SILENT** | Same but skips CONNECTION\_CLOSE (errors, stateless resets) | +| **GRACEFUL** | Sends GOAWAY (H3), waits for streams to close naturally | + +### Timer + +`Session::UpdateTimer()` queries `ngtcp2_conn_get_expiry()` and sets a libuv +timer. When it fires, `OnTimeout()` calls `ngtcp2_conn_handle_expiry()` then +`SendPendingData()` to retransmit lost packets, send PINGs, or retry +pacing-blocked sends. + +## Stream Lifecycle + +### Creation + +**Local streams**: `Session::OpenStream()` calls +`ngtcp2_conn_open_bidi_stream()` or `ngtcp2_conn_open_uni_stream()`. If the +handshake is incomplete or the concurrency limit is reached, the stream is +created in **pending** state and queued. When the peer grants capacity +(`ExtendMaxStreams`), pending streams are fulfilled with real stream IDs. + +**Remote streams**: ngtcp2 notifies via callbacks. The Application creates a +`Stream` object and emits it to JavaScript. + +### Outbound Data Flow + +The `Stream::Outbound` class bridges a `DataQueue` (the data source) to +ngtcp2's packet-writing loop. A `DataQueue::Reader` provides the bob +pull interface. + +Supported body source types (via `GetDataQueueFromSource`): + +| Source | Strategy | +| ------------------- | -------------------------------------------- | +| `ArrayBuffer` | Zero-copy detach, or copy if non-detachable | +| `SharedArrayBuffer` | Always copy | +| `ArrayBufferView` | Zero-copy detach of underlying buffer | +| `Blob` | Slice of Blob's existing DataQueue | +| `String` | UTF-8 encode into BackingStore | +| `FileHandle` | `FdEntry` — async file reads via thread pool | + +For `FileHandle` bodies, the `FdEntry::ReaderImpl` dispatches `uv_fs_read` +to the libuv thread pool and returns `STATUS_WAIT`. When the read completes, +the callback appends data to the Outbound buffer and calls +`session().ResumeStream(id)` to re-enter the send loop. + +### Inbound Data Flow + +Received stream data is delivered by ngtcp2 via +`Application::ReceiveStreamData()`, which calls `stream->ReceiveData()`. +Data is appended to the stream's inbound `DataQueue`. The JavaScript side +consumes this via an async iterator (the `stream/iter` `bytes()` helper). +The stream implements `DataQueue::BackpressureListener` to extend the +QUIC flow control window as data is consumed. + +### Streaming Mode (Writer API) + +When no body is provided at stream creation, the JavaScript `stream.writer` +API uses streaming mode. The Outbound creates a non-idempotent DataQueue. +Each `writeSync()` / `write()` call appends an in-memory entry. The +`endSync()` / `end()` call caps the queue, signaling EOS to the send loop. + +## SessionManager + +The `SessionManager` is a per-Realm singleton that owns the authoritative +CID→Session mapping. It enables: + +* **Cross-endpoint routing**: A session's CIDs are registered globally so + packets arriving on any endpoint find the right session. +* **Connection migration**: When a session migrates to a new path, the + SessionManager updates the routing without requiring endpoint-specific + knowledge. +* **Stateless reset token mapping**: Maps reset tokens to sessions for + detecting stateless resets on any endpoint. + +CID lookup uses a three-tier strategy: + +1. Direct SCID match in `SessionManager::sessions_` +2. Cross-endpoint DCID→SCID in `SessionManager::dcid_to_scid_` +3. Per-endpoint DCID→SCID in `Endpoint::dcid_to_scid_` (peer-chosen CIDs) + +## Address Validation + +The endpoint uses an LRU cache to track validated remote addresses. For +unvalidated addresses: + +1. If no token is present, a **Retry** packet is sent with a cryptographic + token (HKDF-derived, time-limited). +2. The client retransmits the Initial with the retry token. +3. The token is validated; the session is created with the original DCID + preserved for transport parameter verification. + +Regular tokens (from `NEW_TOKEN` frames) follow the same validation path +but without the retry handshake. The LRU cache allows subsequent +connections from the same address to skip validation entirely. + +## HTTP/3 Application (`http3.cc`) + +The `Http3ApplicationImpl` wraps `nghttp3_conn` and handles: + +* **Header compression**: QPACK encoding/decoding via nghttp3's internal + encoder/decoder streams (unidirectional). +* **Stream management**: Only bidirectional streams are exposed to + JavaScript. Unidirectional control, encoder, and decoder streams are + managed internally. +* **FIN management**: `stream_fin_managed_by_application()` returns true. + nghttp3 controls when FIN is sent based on HTTP/3 framing (DATA frames, + trailing HEADERS). The `EndWriting()` notification from JavaScript is + forwarded to `nghttp3_conn_shutdown_stream_write()`. +* **Data read callback**: `on_read_data_callback` pulls data from the + stream's Outbound during `nghttp3_conn_writev_stream`. Bytes must be + committed inside the callback (before `StreamCommit`) because QPACK can + cause re-entrant `read_data` calls. +* **GOAWAY**: `BeginShutdown()` sends a GOAWAY frame. The goaway ID is + deferred to `PostReceive()` (outside callback scopes) so it can safely + invoke JavaScript. +* **Settings**: HTTP/3 SETTINGS (max field section size, QPACK capacities, + CONNECT protocol, datagrams) are negotiated and enforced. Datagram + support follows RFC 9297 — when the peer's SETTINGS disable datagrams, + `sendDatagram()` is blocked. +* **0-RTT**: Early data settings are validated during ticket extraction + (`ValidateTicketData` in `ExtractSessionTicketAppData`). If the server's + settings changed incompatibly, the ticket is rejected before TLS accepts + it. + +## Error Handling + +`QuicError` (`data.h`) encapsulates QUIC error codes with a type namespace +(transport, application, version negotiation, idle close). Factory methods +wrap ngtcp2 error codes, TLS alerts, and application errors. + +On the JavaScript side, `convertQuicError()` transforms the C++ error +representation into `ERR_QUIC_TRANSPORT_ERROR` or +`ERR_QUIC_APPLICATION_ERROR` objects. Clean closes (transport NO\_ERROR, +H3 NO\_ERROR, or idle close) resolve `stream.closed`; all other errors +reject it. + +## Packet Allocation + +Outbound packets are allocated from an `ArenaPool` owned by the +Endpoint. The arena provides O(1) allocation from contiguous memory blocks +(128 slots per block), avoiding per-packet heap allocation and V8 object +overhead. Packets are returned to the pool when the UDP send completes +(via the `Packet::Listener::PacketDone` callback). + +## Debug Logging + +Use the `NODE_DEBUG_NATIVE` environment variable to enable detailed debug +logging: + +* `QUIC` - general QUIC events (sessions, streams, packets) +* `NGTCP2` - ngtcp2 callback events and error codes +* `NGHTTP3` - nghttp3 callback events and error codes + +```bash +NODE_DEBUG_NATIVE=QUIC,NGTCP2,NGHTTP3 node --experimental-quic ... +``` + +The debug output will be printed to stderr and can be extremely verbose. + +Used in combination with `qlog` and `keylog` options when creating a +`QuicSession`, this can help significantly with debugging and understanding +QUIC behavior and identifying bugs / performance issues in the implementation. + +## External Dependencies + +| Library | Role | Location | +| ------- | --------------------------------------- | ------------------------- | +| ngtcp2 | QUIC transport protocol | `deps/ngtcp2/ngtcp2/` | +| nghttp3 | HTTP/3 framing, QPACK | `deps/ngtcp2/nghttp3/` | +| OpenSSL | TLS 1.3 handshake, encryption | system or `deps/openssl/` | +| libuv | UDP sockets, timers, thread pool | `deps/uv/` | +| V8 | JavaScript engine, GC, external strings | `deps/v8/` | diff --git a/src/quic/application.cc b/src/quic/application.cc index 81c1c0ebe5f49c..0d5dd994f8caaf 100644 --- a/src/quic/application.cc +++ b/src/quic/application.cc @@ -1,3 +1,4 @@ +#include "util.h" #if HAVE_OPENSSL && HAVE_QUIC #include "guard.h" #ifndef OPENSSL_NO_QUIC @@ -34,6 +35,8 @@ const Session::Application_Options Session::Application_Options::kDefault = {}; Session::Application_Options::operator const nghttp3_settings() const { // In theory, Application::Options might contain options for more than just // HTTP/3.
