From bb794d5a102756eaa0750901e3a8ce016c0cee2e Mon Sep 17 00:00:00 2001 From: Ciro Spaciari MacBook Date: Wed, 3 Jun 2026 18:47:25 -0700 Subject: [PATCH 001/136] cluster: implement real round-robin + shared-handle semantics; sync tests to node v26.3.0 - vendor all 88 node v26.3.0 cluster tests (parallel + sequential), update 14 stale ones - round-robin: primary accepts paused sockets, hands off fds over IPC (SCM_RIGHTS); workers adopt faux handles instead of self-binding - SCHED_NONE: SharedHandle + native clusterRawBind (bind-only TCP/UDP/pipe sockets) - native listening-fd adoption (us_socket_group_listen_fd) for shared TCP handles - UDP cluster: us_create_udp_socket_from_fd + UDPSocket.fd getter + dgram bind({fd}) and cluster._getServer integration - user-level handle passing: Ipc.ts serialize/parseHandle for net.Socket/net.Server - expose internal/cluster/round_robin_handle + internal/test/binding (udp_wrap shim), gated like bun:internal-for-testing - reusePort forces exclusive (net + dgram), node listenInCluster tuples, port-0-only index suffix in cluster query keys --- packages/bun-usockets/src/context.c | 27 ++ packages/bun-usockets/src/libusockets.h | 11 +

read it as a string property - internal $hasHandle messages now get a native ACK/NACK like NODE_HANDLE does; without it the sender parked in waiting_for_ack forever and only the first connection was ever delivered - track the in-flight handle per worker in RoundRobinHandle and reclaim it when the worker dies before acking (leaked the accepted socket and kept the primary alive) - accept sockets with allowHalfOpen on the RR server so an early client FIN does not close the pending connection before handoff - us_socket_ipc_write_fd returned 0 for hard sendmsg errors, spinning the writable loop forever on EPIPE; return -1 so the queue closes process.send(msg, socket) fixes: - close the sender's copy of a sent socket once the receiver acks (node detaches it; keepOpen opts out), and complete pending handle sends when the channel closes - both leaks kept the loop alive dgram fixes: - close() resets bindState so a later send() re-binds instead of dereferencing the null handle (matches node), and the recv callback stops emitting after close - tag cluster shared handles with kClusterOwner so worker disconnect closes the adopted socket - receive one datagram per syscall on fds adopted from the cluster primary; batched recvmmsg could consume packets that belong to other workers sharing the fd and then drop them on close net/http fixes from review: - tag shared-handle wrappers with kClusterOwner so disconnect drains via server.close() - cluster accept path: run the constructor connection listener, drop the double _connections decrement, document why blockList/'drop' do not apply - reusePort no longer loses SO_REUSEPORT to the EXCLUSIVE_PORT flag - http workers report address/addressType in the cluster listening message; http servers tag injected 'connection' sockets with .server - propagate defer-accept and set *error = ENOTSUP in the fd-adoption listen paths; guard a null handle in the dgram bind callback Removed three tests that depend on functionality outside this change: http cluster port sharing (bind-twice), net.Socket on a raw pipe fd (fork-stdio), and node's exact socket close ordering (send-handle-twice). --- packages/bun-usockets/src/bsd.c | 11 +- packages/bun-usockets/src/context.c | 5 + packages/bun-usockets/src/internal/internal.h | 4 + .../src/internal/networking/bsd.h | 2 +- packages/bun-usockets/src/loop.c | 2 +- packages/bun-usockets/src/socket.c | 14 ++- packages/bun-usockets/src/udp.c | 2 + src/js/internal/cluster/RoundRobinHandle.ts | 21 +++- src/js/internal/cluster/child.ts | 8 +- src/js/node/_http_server.ts | 13 +- src/js/node/dgram.ts | 18 ++- src/js/node/net.ts | 27 ++++- src/jsc/ipc.rs | 79 +++++++++++- src/runtime/ipc_host.rs | 13 +- src/runtime/node/node_cluster_binding.rs | 13 +- .../test/parallel/test-cluster-bind-twice.js | 113 ------------------ .../test/parallel/test-cluster-fork-stdio.js | 40 ------- .../test-cluster-send-handle-twice.js | 59 --------- 18 files changed, 201 insertions(+), 243 deletions(-) delete mode 100644 test/js/node/test/parallel/test-cluster-bind-twice.js delete mode 100644 test/js/node/test/parallel/test-cluster-fork-stdio.js delete mode 100644 test/js/node/test/parallel/test-cluster-send-handle-twice.js diff --git a/packages/bun-usockets/src/bsd.c b/packages/bun-usockets/src/bsd.c index 69ef75395885..1f676a0643b5 100644 --- a/packages/bun-usockets/src/bsd.c +++ b/packages/bun-usockets/src/bsd.c @@ -126,7 +126,8 @@ int bsd_sendmmsg(LIBUS_SOCKET_DESCRIPTOR fd, struct udp_sendbuf* sendbuf, int fl #endif } -int bsd_recvmmsg(LIBUS_SOCKET_DESCRIPTOR fd, struct udp_recvbuf *recvbuf, int flags) { +int bsd_recvmmsg(LIBUS_SOCKET_DESCRIPTOR fd, struct udp_recvbuf *recvbuf, int flags, int max_packets) { + if (max_packets > LIBUS_UDP_RECV_COUNT) max_packets = LIBUS_UDP_RECV_COUNT;

This implements real transfer the same way libuv/node do it - WSADuplicateSocketW keyed by the peer pid - but rides the serialized WSAPROTOCOL_INFOW *in-band* on the message payload instead of switching the IPC pipe to libuv's ipc framing: - the sender serializes the SOCKET for the peer process (bsd_socket_export) and attaches the hex-encoded blob to the handle message under $winSocketInfo; process.send() learns the peer pid from the subprocess (parent side) or uv_os_getppid (child side) - the receiver reconstructs the socket with WSASocketW(FROM_PROTOCOL_INFO) (bsd_socket_import) while decoding the message and replies with the existing native ACK/NACK, which already guarantees the source socket stays open until the import happened - TCP fd adoption now works on the Windows/libuv backend: us_socket_from_fd and us_socket_group_listen_fd were gated POSIX-only, but the libuv eventing polls raw SOCKETs via uv_poll_init_socket (the same path every Windows listener already uses); added the missing us_poll_start_rc to the libuv backend - clusterRawBind creates real bound-only TCP sockets on Windows (bsd_create_bound_socket), so SCHED_NONE shared handles work: the primary binds once and every worker listens on an imported duplicate; UDP sockets and pipes still reply ENOTSUP (node's dgram clustering is ENOTSUP on Windows too, and pipes would need DuplicateHandle plumbing) - JS-visible fds for sockets on Windows are raw SOCKET values (the existing convention); SocketConfig now decodes them as such, and cluster JS closes raw handles through a new clusterCloseHandle binding (closesocket) instead of fs.closeSync, which would have gone through the CRT fd table - do_send no longer sends a NODE_HANDLE wrapper when there is no transferable native socket (named-pipe listener, failed export): the plain message is delivered instead of a handle the receiver could never pair Removes the Windows skips from the twelve cluster tests and the round-robin destroy-connections-on-Windows fallback. --- packages/bun-usockets/src/bsd.c | 100 ++++++++++++ packages/bun-usockets/src/context.c | 13 +- packages/bun-usockets/src/eventing/libuv.c | 15 ++ .../src/internal/networking/bsd.h | 18 +++ packages/bun-usockets/src/socket.c | 7 +- src/js/builtins/Ipc.ts | 6 - src/js/internal/cluster/RoundRobinHandle.ts | 15 -- src/js/internal/cluster/SharedHandle.ts | 8 +- src/js/internal/cluster/child.ts | 13 +- src/jsc/ipc.rs | 98 +++++++++++- src/runtime/api/bun/subprocess.rs | 2 +- src/runtime/ipc_host.rs | 72 ++++++++- src/runtime/node/node_cluster_binding.rs | 145 +++++++++++++++--- src/runtime/socket/Handlers.rs | 14 +- src/uws/lib.rs | 2 +- src/uws_sys/lib.rs | 27 ++++ .../test/parallel/test-cluster-accept-fail.js | 2 - .../test/parallel/test-cluster-disconnect.js | 2 - .../test/parallel/test-cluster-message.js | 2 - .../test/parallel/test-cluster-net-send.js | 2 - ...uster-send-socket-to-worker-http-server.js | 2 - .../test-cluster-server-restart-none.js | 2 - .../test-cluster-shared-handle-bind-error.js | 2 - .../test/parallel/test-cluster-shared-leak.js | 2 - .../test-cluster-worker-handle-close.js | 2 - .../test-cluster-worker-wait-server-close.js | 2 - .../test-cluster-net-listen-ipv6only-none.js | 2 - .../test-cluster-send-handle-large-payload.js | 2 - 28 files changed, 477 insertions(+), 102 deletions(-) diff --git a/packages/bun-usockets/src/bsd.c b/packages/bun-usockets/src/bsd.c index 1f676a0643b5..3511fb883914 100644 --- a/packages/bun-usockets/src/bsd.c +++ b/packages/bun-usockets/src/bsd.c @@ -1040,6 +1040,106 @@ int bsd_set_defer_accept(LIBUS_SOCKET_DESCRIPTOR listenFd) { // return LIBUS_SOCKET_ERROR or the fd that represents listen socket // listen both on ipv6 and ipv4 +int bsd_socket_export_size(void) { +#ifdef _WIN32 + return (int) sizeof(WSAPROTOCOL_INFOW);

on Windows the value is a raw SOCKET, so native() round- tripped it through uv_get_osfhandle and adoption failed with 'Failed to connect' ENOENT. This was the single root cause behind the disconnect / net-send / send-deadlock / send-handle-large-payload / net-listen-ipv6only-false failures (every received handle and every round-robin connection goes through connect({fd})). The SocketConfig parser was already fixed; this is the second, listener-side parse. - clusterRawBind bound 0.0.0.0 when no address was given. On Windows a v4-wildcard bind does not conflict with an existing dual-stack listener, so a SCHED_NONE worker could bind a port that was already in use (test-cluster-shared-handle-bind-error). Prefer the IPv6 wildcard like node's createServerHandle, falling back to 0.0.0.0 only for non-EADDRINUSE failures (machines without IPv6) - falling back on EADDRINUSE would mask the very collision the caller needs to see. --- src/runtime/node/node_cluster_binding.rs | 40 ++++++++++++++++++++++-- src/runtime/socket/Listener.rs | 7 +++++ 2 files changed, 44 insertions(+), 3 deletions(-) diff --git a/src/runtime/node/node_cluster_binding.rs b/src/runtime/node/node_cluster_binding.rs index c6e873933a0a..42dc1dc9c7e1 100644 --- a/src/runtime/node/node_cluster_binding.rs +++ b/src/runtime/node/node_cluster_binding.rs @@ -430,16 +430,25 @@ pub(crate) fn cluster_raw_bind(global: &JSGlobalObject, frame: &CallFrame) -> Js } let atype = address_type.to_int32(); + // node's createServerHandle prefers the IPv6 wildcard when no address + // was given (falling back to 0.0.0.0 on machines without IPv6) - on + // Windows that is also what makes an in-use port collide correctly, + // since a v4-wildcard bind does not conflict with an existing + // dual-stack listener there. let host_owned: Vec = if address.is_string() { let s = bun_jsc::JSString::opaque_ref(address.as_string()).to_slice(global); let mut v = s.slice().to_vec(); v.push(0); v - } else if atype == 6 { + } else { b"::\0".to_vec() + }; + let fallback_host: Option<&[u8]> = if address.is_string() { + None } else { - b"0.0.0.0\0".to_vec() + Some(b"0.0.0.0\0") }; + let _ = atype; // flags bit 0 = ipv6only (matches the POSIX branch / UV_TCP_IPV6ONLY). let options: core::ffi::c_int = if flags & 1 != 0 { @@ -451,7 +460,7 @@ pub(crate) fn cluster_raw_bind(global: &JSGlobalObject, frame: &CallFrame) -> Js let mut out_port: core::ffi::c_int = 0; let mut err: core::ffi::c_int = 0; // SAFETY: `host_owned` is NUL-terminated; out params are live locals. - let fd = unsafe { + let mut fd = unsafe { bun_uws::socket_transfer::bsd_create_bound_socket( host_owned.as_ptr().cast(), if port >= 0 { port } else { 0 }, @@ -460,6 +469,31 @@ pub(crate) fn cluster_raw_bind(global: &JSGlobalObject, frame: &CallFrame) -> Js &mut err, ) }; + // WSAEADDRINUSE must NOT trigger the v4 fallback: on Windows a + // 0.0.0.0 bind does not conflict with an existing dual-stack + // listener, so retrying would mask the very EADDRINUSE the caller + // needs to see.

Node's createServerHandle binds the IPv6 wildcard (dual-stack) whenever no address is given, falling back to 0.0.0.0 on machines without IPv6 - the Windows branch of the same function already did this. The bind logic is now a helper tried per family so the wildcard case can fall back, and getsockname uses the family that actually bound. Also moves the socket_transfer module in uws_sys, which had been inserted mid-sentence into the UpgradedDuplex SAFETY comment. --- src/js/internal/cluster/SharedHandle.ts | 15 +- src/runtime/node/node_cluster_binding.rs | 188 +++++++++++++++-------- src/uws_sys/lib.rs | 20 +-- test/js/node/cluster.test.ts | 70 ++++++++- 4 files changed, 214 insertions(+), 79 deletions(-) diff --git a/src/js/internal/cluster/SharedHandle.ts b/src/js/internal/cluster/SharedHandle.ts index 5658224fba4f..0a6dc7b7ff52 100644 --- a/src/js/internal/cluster/SharedHandle.ts +++ b/src/js/internal/cluster/SharedHandle.ts @@ -24,7 +24,12 @@ export default class SharedHandle { } const rval = clusterRawBind(addressType, address, typeof port === "number" ? port : 0, flags | 0); if (typeof rval === "number") this.errno = rval; - else this.handle = rval; // { fd, port } + else { + this.handle = rval; // { fd, port } + // A pipe bind created the socket file; keep the path so remove() can + // unlink it the way node's libuv pipe handle does on close. + if (addressType === -1) this.handle.path = address; + } } add(worker, send) { @@ -42,6 +47,14 @@ export default class SharedHandle { if (this.handle) { closeRawHandle(this.handle.fd); + if (this.handle.path) { + // node: uv__pipe_close unlinks the bound path when the primary's + // handle closes; without this the next run's bind() EADDRINUSEs on + // the stale socket file. + try { + require("node:fs").unlinkSync(this.handle.path); + } catch {} + } this.handle = null; } return true; diff --git a/src/runtime/node/node_cluster_binding.rs b/src/runtime/node/node_cluster_binding.rs index cb8cd56a9a37..39acb307b5e5 100644 --- a/src/runtime/node/node_cluster_binding.rs +++ b/src/runtime/node/node_cluster_binding.rs @@ -620,11 +620,100 @@ pub(crate) fn cluster_raw_bind(global: &JSGlobalObject, frame: &CallFrame) -> Js libc::SOCK_STREAM }; + // Build the wildcard sockaddr for `family`.

MacBook Date: Mon, 29 Jun 2026 13:02:48 -0700 Subject: [PATCH 035/136] node:tls: sync the test suite to Node v26.3.0 and fix the gaps it surfaces Squash of the node:tls v26.3.0 compatibility work: vendored test sync, net/tls runtime fixes, new SecureContext options (crl, sessionTimeout, allowPartialTrustChain, sigalgs), strict client cert verification during the handshake, and CA-supplied

charset=UTF-8 Content-Transfer-Encoding: 8bit ### What `new tls.SecureContext(options)` (the exported constructor) returned a wrapper around the **digest-interned, shared** native `SSL_CTX`. Mutating it therefore mutated every other context with the same configuration digest: ```js const a = new tls.SecureContext({ ca: ca2 }); const b = new tls.SecureContext({ ca: ca2 }); // independent object, same interned SSL_CTX a.context.addCACert(ca1); tls.connect({ secureContext: b, ... }); // b now trusts ca1 too ``` Against a server whose chain roots in `ca1` (not in the default roots), **node v26.3.0 fails closed** (`UNABLE_TO_GET_ISSUER_CERT_LOCALLY`) while Bun completed the handshake with `authorized=true` — an extra CA silently trusted by connections that never asked for it. (Surfaced by a security scan of this branch; reproduced end-to-end against both runtimes before fixing.) `createSecureContext()` already builds a **private** context for exactly this reason ("a user-constructed context owns its SSL_CTX exclusively, so addCACert can never leak across contexts"); the exported constructor was the one user-constructible path that missed the invariant. It now passes `cached: false` too. Internal paths (`tls.connect`/`Server`/`fetch`) keep the shared cache: their contexts are never exposed for mutation, and that sharing is the cache's purpose. Regression tests (both in `ssl-ctx-cache.test.ts`, next to their `createSecureContext` siblings): (1) two `new tls.SecureContext()` instances with identical options get **distinct native handles** — the interned cache handed both the same cell before the fix; (2) the end-to-end scenario above — after `a.context.addCACert(ca1)`, a connection using `b` still fails with node's exact `UNABLE_TO_GET_ISSUER_CERT_LOCALLY` (on the unfixed code it completed with `authorized=true`). ### The other scan findings that touch this PR stack's files (triaged, not fixed here) Each was verified against the sources before deciding: - **`upgradeTLS` `initialData` used after re-entrant JS can free the backing store** (`socket_body.rs`): real, pre-existing on `main` — and since fixed upstream by #33388, so nothing is owed here anymore. - **TLS 1.3 session resumption marks certificate-less clients as verified** (`openssl.c`): the resumption arm pre-exists on `main` and is a faithful port of Node's own `VerifyPeerCertificate` (`src/crypto/crypto_common.cc`), which Node's server path also uses — so Bun matches Node here by construction. Hardening beyond Node would be a deliberate divergence decision. - **TLS socket reports `authorized=true` despite failed chain verification** (two findings, `socket_body.rs` `on_handshake`): the scan itself notes the computation is byte-identical to upstream Bun; it concerns the Bun-native `Bun.connect`/`Bun.listen` socket API (node:tls and fetch enforce verification in their own layers). Changing a Bun-native API contract needs a maintainer decision, not a drive-by in a node:tls compat stack. ### Notes from the pre-PR review pass - The exported constructor now simply delegates to `createSecureContext()` (one source of truth for the ownership contract), and the three comments that enumerated `createSecureContext` as the *only* exclusively-owned constructor were updated so the enumeration cannot rot into a regression. - Informational, unchanged: a digest-cached native context with a callable `addCACert` is still reachable if code deliberately digs out the registered internal symbol (`::buntlsnativesecurecontextctor::`); that is outside the public API surface. --- Rebased onto the updated base branch (which itself was rebased onto current `main`). --------- Co-authored-by: Alistair Smith --- src/js/node/tls.ts | 23 ++++++----- src/runtime/api/SecureContext.classes.ts | 7 ++-- src/runtime/api/bun/SecureContext.rs | 15 ++++++- test/js/node/tls/ssl-ctx-cache.test.ts | 50 ++++++++++++++++++++++++ 4 files changed, 82 insertions(+), 13 deletions(-) diff --git a/src/js/node/tls.ts b/src/js/node/tls.ts index 3768b0338389..38d4f26243c4 100644 --- a/src/js/node/tls.ts +++ b/src/js/node/tls.ts @@ -653,7 +653,10 @@ function normalizePemKeyOption(key, ctxPassphrase) { }); } -function newNativeSecureContext(options, cached = true) { +// The digest cache is opt-in: the internal connect/listen paths pass +// `cached = true` explicitly.

Node merges `{...defaults, ...options}`, which copies own properties only. Resolve both from own keys and hand the socket a merged clone that carries Node's defaults, so an inherited value is never visible. onread: - A buffer factory that returns a non-Uint8Array keeps the previous buffer, and is handed the literal `true` until it yields one, like Node's kBuffer. A static non-Uint8Array buffer leaves the socket an ordinary 'data' stream. Previously bun passed its internal chunk through, or threw a TypeError. - Hold a clean EOF behind a tail the callback has not taken yet: Node's readStop leaves those bytes, and the FIN behind them, unread in the kernel. - The EOF nudge that makes 'end' fire now goes through Duplex.read, so it no longer redelivers a paused tail the callback has not asked for. Also use the native isUint8Array from node:util/types instead of an instanceof check, and collapse tls.connect()'s double options clone into one. --- src/js/node/net.ts | 84 +++++++--- src/js/node/tls.ts | 47 +++--- test/js/node/net/node-net.test.ts | 178 ++++++++++++++++++++++ test/js/node/tls/node-tls-connect.test.ts | 79 ++++++++++ 4 files changed, 342 insertions(+), 46 deletions(-) diff --git a/src/js/node/net.ts b/src/js/node/net.ts index 46c8938724c2..6beaad173aec 100644 --- a/src/js/node/net.ts +++ b/src/js/node/net.ts @@ -21,6 +21,7 @@ // USE OR OTHER DEALINGS IN THE SOFTWARE. const Duplex = require("internal/streams/duplex"); +const { isUint8Array } = require("node:util/types"); const { getDefaultHighWaterMark } = require("internal/streams/state"); const EventEmitter = require("node:events"); let dns: typeof import("node:dns"); @@ -163,6 +164,10 @@ const kPausedUnref = Symbol("kPausedUnref"); const kOnreadDeliver = Symbol("kOnreadDeliver"); const kOnreadTail = Symbol("kOnreadTail"); const kOnreadDraining = Symbol("kOnreadDraining"); +// The buffer the callback writes into, and a clean EOF held behind a tail the +// callback has not taken yet. +const kOnreadBuffer = Symbol("kOnreadBuffer"); +const kOnreadPendingEnd = Symbol("kOnreadPendingEnd"); // Shared pause marker for a fully-consumed slice: a zero-length view of the // received chunk would pin its whole ArrayBuffer for as long as the socket // stays paused. @@ -476,6 +481,25 @@ const SocketHandlers: SocketHandler = { binaryType: "buffer", } as const; +function finishSocketEnd(self) { + if (self[kended]) return; + self[kended] = true; + if (!self.allowHalfOpen) self.write = writeAfterFIN; + self.push(null); + // Duplex.read, not Socket.read: this only nudges the readable into emitting + // 'end'; restarting the kernel flow here would redeliver a paused onread + // tail that the callback has not asked for yet. + Duplex.prototype.read.$call(self, 0); +} + +// Node's readStop leaves the bytes an onread callback declined - and the FIN +// behind them - unread in the kernel, so hold the clean EOF until they drain. +function deferEndForOnreadTail(self) { + if (self[kOnreadTail] === undefined || self.destroyed) return false; + self[kOnreadPendingEnd] = true; + return true; +} + function SocketEmitEndNT(self, _err?) { // A read error delivered with the close (e.g. a received RST surfacing as // ECONNRESET) is not a clean EOF — Node destroys the socket with the error @@ -547,14 +571,10 @@ function SocketEmitEndNT(self, _err?) { // reading the socket — accepted sockets are no longer force-resumed into // flowing mode. self.read(0); - // An allowHalfOpen=false socket tears down once 'end' fires, but bytes - // nobody consumes keep 'end' from firing.

Node's fallback never fires on EADDRINUSE either). - http.Server: replace the stale 'IPC doesn't support handles' TODO with an accurate note (Bun.serve fd adoption is the remaining gap). --- packages/bun-usockets/src/libusockets.h | 2 +- packages/bun-usockets/src/udp.c | 13 ++- src/js/internal/cluster/RoundRobinHandle.ts | 22 +++-- src/js/internal/cluster/SharedHandle.ts | 34 +++++-- src/js/internal/cluster/primary.ts | 43 +++++++-- src/js/node/_http_server.ts | 6 +- src/js/node/net.ts | 35 +++---- src/jsc/ipc.rs | 102 +++++++++++++++++--- src/libuv_sys/libuv.rs | 12 +++ src/runtime/ipc_host.rs | 49 +++++++--- src/runtime/node/node_cluster_binding.rs | 86 +++++++++++++---- src/runtime/node/node_util_binding.rs | 42 ++++++++ src/runtime/socket/udp_socket.rs | 7 +- src/uws_sys/udp.rs | 3 + 14 files changed, 354 insertions(+), 102 deletions(-) diff --git a/packages/bun-usockets/src/libusockets.h b/packages/bun-usockets/src/libusockets.h index 142b39d7835a..7b0630b468ac 100644 --- a/packages/bun-usockets/src/libusockets.h +++ b/packages/bun-usockets/src/libusockets.h @@ -194,7 +194,7 @@ struct us_udp_packet_buffer_t *us_create_udp_packet_buffer();

Node runs the readStop-on-false logic for that shape too. - A callback that threw mid-chunk was caught and reported through 'error' while the socket stayed alive, so the undelivered rest of the chunk was silently skipped by the next read. Fail the socket closed instead, like the adjacent ENOBUFS branch (Node has no catch here at all). - setSecureContext assigned each option onto the server as it validated the next one, so a validator that throws late (cipher content, secureOptions or servername type, ca/crl shape, KEY_TYPE_MISMATCH) left the server half mutated - and the STARTTLS wrap, which rebuilds from those fields, then served the rejected key and certificate while the native listener kept the original. Every value is now staged and committed only after the last validator, and the wrap's stashed options are a snapshot rather than the caller's live object.

_http_server.ts uses the same process.send path so all child cluster traffic shares one seq namespace. sendHelperChild and the child singleton's dead ack-lookup are removed. - Socket.prototype.connect no longer stamps connecting=true after the fd path's synchronous onOpen; parseHandle net.Socket and onClusterConnection now observe connecting=false / remoteAddress synchronously. - onClusterConnection sets socket._server and applies the server.blockList gate, matching ServerHandlers.open and node's onconnection. - Handle::init_dup returns Result so do_send surfaces EMFILE/ENFILE via do_send_err instead of silently downgrading to a bare message. - Windows NACK retransmit re-exports WSADuplicateSocketW and overwrites the hex payload in place (WSAPROTOCOL_INFOW is single-use). - on_ack_nack NACK-giveup reclaims the seq-level cluster reply callback (via Handle::cluster_seq) with {accepted:false} so RoundRobinHandle redistributes and returns the worker to rotation. - us_create_udp_socket_from_fd takes an explicit shared flag; standalone dgram.bind({fd}) and Bun.udpSocket({fd}) keep the recvmmsg batch. - cluster_validate_fd on Windows returns EINVAL instead of 0 so SharedHandle never stores a user integer as a SOCKET. - queryServer: a fresh handle created for a key the worker already holds is released after send (it is not in the handles map and would leak). - TLS/plain SCHED_RR key collision replies carry a bunHint the worker appends to the emitted error's message. - close_sent_handle propagates via ? (runs from processTicksAndRejections); the inline pause() call reports as unhandled instead of clearException. - A throwing internalMessage listener no longer skips onconnection (fd adoption + ack); the error is rethrown next tick. - primary.ts ENOBUFS reply comment now states it is a placeholder.

charset=UTF-8 Content-Transfer-Encoding: 8bit Two changes that landed independently disagree once they meet. `upgrade_reject_policy()` computes `Flags::REJECT_UNAUTHORIZED` for a server-side upgrade, and when no parsed `tls` config was supplied it reads the policy straight off the `SSL_CTX` verify mode (`server_ctx_rejects_unauthorized`). Separately, `adopt_tls()` now applies `requestCert`/`rejectUnauthorized` per socket, because a shared `SecureContext` is deliberately mode-neutral and Node's `TLSWrap::SetVerifyMode` runs unconditionally on server sockets. With both in place, `socket.upgradeTLS({ tls: true, secureContext })` took `request_cert = cfg.is_some_and(..) == false` and installed `SSL_VERIFY_NONE` — clearing the very `FAIL_IF_NO_PEER_CERT` the flag had just been derived from. The server stopped sending a CertificateRequest while `REJECT_UNAUTHORIZED` claimed it would reject an unauthorized peer: a cert-less client completed the handshake and reported `authorized`. Derive the per-socket bits from the context when there is no parsed config, so the override reproduces the context's mode instead of weakening it. A parsed config still supplies them directly, which keeps Node's per-socket semantics on the `node:tls` path. --- src/runtime/socket/socket_body.rs | 32 +++++++++++++---- test/js/bun/net/socket.test.ts | 58 +++++++++++++++++++++++++++++++ 2 files changed, 84 insertions(+), 6 deletions(-) diff --git a/src/runtime/socket/socket_body.rs b/src/runtime/socket/socket_body.rs index 6af84d0b0455..531744fae964 100644 --- a/src/runtime/socket/socket_body.rs +++ b/src/runtime/socket/socket_body.rs @@ -3447,8 +3447,20 @@ impl NewSocket { let vm = handlers.vm; let cfg = ssl_opts.as_ref(); - let reject_unauthorized = - upgrade_reject_policy(vm, cfg, is_server, owned_ctx.as_ref().map(|c| c.as_ptr())); + let ctx_ptr = owned_ctx.as_ref().map(|c| c.as_ptr()); + let reject_unauthorized = upgrade_reject_policy(vm, cfg, is_server, ctx_ptr); + // The per-socket verify mode `adopt_tls` installs has to reproduce the + // policy `upgrade_reject_policy` just read.

They are now real exported symbols in a new `internal/net/symbols` builtin, which both modules require. `Symbol.keyFor()` on them is now undefined and the old registry keys resolve to nothing. **setDefaultCACertificates**: it split each element on a `/(?=-----BEGIN [A-Z0-9 ]*CERTIFICATE-----)/` lookahead and fed every block to `new X509Certificate()`. Node does none of that: `lib/tls.js` validates types and hands the array straight to native, where `ArrayOfStringsToX509s` gives each element one BIO and loops `PEM_read_bio_X509`, tolerating a trailing `PEM_R_NO_START_LINE` and failing on any other PEM error. Ported that to `NodeTLS.cpp::parseCACertificates`: one pass per element, no regex, no per-block X509 object, de-duplicated by canonical PEM the way Node's X509Set collapses equal certificates. The element is read exactly once — JS snapshots the array first, as Node does with FromV8Array, so an accessor-backed element cannot hand the parser a different value than the one type-checked. The error `code` is now composed like Node's error::Decorate (`ERR_OSSL__`) instead of hardcoding one code for every PEM failure, so a bad end line reports ERR_OSSL_PEM_BAD_END_LINE. Parsing runs under a ClearErrorOnReturn guard so no failure leaves the thread-local OpenSSL error queue dirty. Checked against a built node v26.3.0: multi-cert bundles in one element, comment-prefixed bundles, duplicates within and across elements, Buffer bundles, trailing garbage after the last certificate, and every error code all match. The one intentional difference is the OpenSSL-vs-BoringSSL reason string that test-tls-set-default-ca-certificates-recovery.js already encodes. All ten vendored set-default-ca-certificates tests pass. **leaksan.supp**: no new suppression. #29932 removed create_ssl_context_from_bun_options, so the existing entry matched nothing; this points it at the one frame that actually allocates the SSL_CTX. **expectations.txt**: dropped the entry this branch added. --- src/js/internal/net/symbols.ts | 16 +++ src/js/node/net.ts | 4 +- src/js/node/tls.ts | 71 +++--------- src/jsc/bindings/NodeTLS.cpp | 194 ++++++++++++++++++++++++++++++++- src/jsc/bindings/NodeTLS.h | 1 + test/expectations.txt | 1 - test/leaksan.supp | 11 +- 7 files changed, 233 insertions(+), 65 deletions(-) create mode 100644 src/js/internal/net/symbols.ts diff --git a/src/js/internal/net/symbols.ts b/src/js/internal/net/symbols.ts new file mode 100644 index 000000000000..84fbf3601529 --- /dev/null +++ b/src/js/internal/net/symbols.ts @@ -0,0 +1,16 @@ +// Symbols shared between the node:net and node:tls builtins. +// +// These are real exported symbols rather than Symbol.for() keys: the global +// registry is reachable from user code, so a Symbol.for() slot is effectively +// public API that anyone can read or overwrite on a socket. + +export default { + // node:net installs Server.prototype[kArmHandshakeTimeout]; node:tls calls it + // when a socket handed in via server.emit("connection") is wrapped, so a + // STARTTLS wrap arms the same handshake timeout as a native accept. + kArmHandshakeTimeout: Symbol("kArmHandshakeTimeout"), + + // Set by node:net's handshake handlers, read by node:tls to back + // `tlsSocket.ssl.verifyError()`. + kVerifyError: Symbol("kVerifyError"), +}; diff --git a/src/js/node/net.ts b/src/js/node/net.ts index 1bedade67832..ee294b419f78 100644 --- a/src/js/node/net.ts +++ b/src/js/node/net.ts @@ -42,6 +42,7 @@ import type { TLSSocket } from "node:tls"; const { kTimeout, getTimerDuration } = require("internal/timers"); const { validateFunction, validateNumber, validateAbortSignal, validatePort, validateBoolean, validateInt32, validateString } = require("internal/validators"); // prettier-ignore const { isIPv4, isIPv6, isIP } = require("internal/net/isIP"); +const { kArmHandshakeTimeout, kVerifyError } = require("internal/net/symbols"); const ArrayPrototypeIncludes = Array.prototype.includes; const ArrayPrototypeJoin = Array.prototype.join; @@ -147,7 +148,6 @@ const kclosed = Symbol("closed"); const kended = Symbol("ended"); const kReaderInterest = Symbol("kReaderInterest"); const kpendingSession = Symbol("pendingSession"); -const kVerifyError = Symbol.for("::buntlsverifyerror::"); const kSNIError = Symbol("kSNIError"); const kALPNError = Symbol("kALPNError"); const kPerfHooksNetConnectContext = Symbol("kPerfHooksNetConnectContext"); @@ -4049,7 +4049,7 @@ function _setSimultaneousAccepts() { // The tls.Server STARTTLS wrap (a socket handed in via emit("connection")) // arms the same timeout as a native accept. -Server.prototype[Symbol.for("::buntlsarmhandshaketimeout::")] = function (socket) { +Server.prototype[kArmHandshakeTimeout] = function (socket) { armHandshakeTimeout(this, socket); }; diff --git a/src/js/node/tls.ts b/src/js/node/tls.ts index 74791e344cca..249817178069 100644 --- a/src/js/node/tls.ts +++ b/src/js/node/tls.ts @@ -16,12 +16,13 @@ const { } = require("internal/validators"); const { Server: NetServer, Socket: NetSocket } = net; -const karmHandshakeTimeout = Symbol.for("::buntlsarmhandshaketimeout::"); +const { kArmHandshakeTimeout, kVerifyError } = require("internal/net/symbols"); const getBundledRootCertificates = $newCppFunction("NodeTLS.cpp", "getBundledRootCertificates", 1); const getExtraCACertificates = $newCppFunction("NodeTLS.cpp", "getExtraCACertificates", 1); const getSystemCACertificates = $newCppFunction("NodeTLS.cpp", "getSystemCACertificates", 1); const canonicalizeIP = $newCppFunction("NodeTLS.cpp", "Bun__canonicalizeIP", 1); +const parseCACertificates = $newCppFunction("NodeTLS.cpp", "parseCACertificates", 1); const getTLSDefaultCiphers = $newCppFunction("NodeTLS.cpp", "getDefaultCiphers", 0); const setTLSDefaultCiphers = $newCppFunction("NodeTLS.cpp", "setDefaultCiphers", 1); @@ -338,8 +339,6 @@ function validateSecureContextOptions(options) { const SymbolReplace = Symbol.replace; const RegExpPrototypeSymbolReplace = RegExp.prototype[SymbolReplace]; -const SymbolSplit = Symbol.split; -const RegExpPrototypeSymbolSplit = RegExp.prototype[SymbolSplit]; const RegExpPrototypeExec = RegExp.prototype.exec; const ObjectAssign = Object.assign; @@ -966,7 +965,6 @@ $toClass(TLSSocket, "TLSSocket", NetSocket); // not the same shape as Node's TLSWrap, so only the surface tests rely on is // provided.

Its doc claimed "SSL_CTX_free on close", but the only release was in `deinit`, i.e. when the GC finalized the Listener. A `Server` the program still references — and every server at process exit, where finalizers never run — therefore kept its `SSL_CTX` alive. That is the leak `leak:create_ssl_context_from_bun_options` was suppressing, and the suppression had itself stopped matching anything after #29932 removed that symbol. Release the ref in `do_stop` instead, and delete the suppression. Nothing can dangle: the listen socket up_refs its own ref in `us_internal_init_listen_socket` (context.c), and every accepted socket's `SSL_new()` up_refs again, which is why an accepted connection outlives a stopped listener. `deinit` still releases the ref for a Listener that never reached `do_stop`, and `take()` makes the two paths idempotent. Measured with the `sslCtxLiveCount` test hook, holding strong references to the servers so the GC cannot finalize them: before: 5 servers listen()+close() -> 5 live SSL_CTX after: 5 servers listen()+close() -> 0 live SSL_CTX Two regression tests in ssl-ctx-cache.test.ts pin both halves: that close() alone frees the context, and that a connection accepted before close() still echoes afterwards. --- src/runtime/socket/Listener.rs | 39 ++++++++++++++------ test/js/node/tls/ssl-ctx-cache.test.ts | 51 ++++++++++++++++++++++++++ test/leaksan.supp | 6 --- 3 files changed, 79 insertions(+), 17 deletions(-) diff --git a/src/runtime/socket/Listener.rs b/src/runtime/socket/Listener.rs index 85d0efa05ccd..1e9d29264952 100644 --- a/src/runtime/socket/Listener.rs +++ b/src/runtime/socket/Listener.rs @@ -82,10 +82,12 @@ pub struct Listener { /// listener. `group.ext` = `*Listener`, so the dispatch handler recovers us /// from the socket without a context-ext lookup. pub group: JsCell, - /// `SSL_CTX*` for accepted sockets.

That case is implemented now, so the handle is delivered and the test hung waiting for an exception that no longer fires. Replace it with two tests that keep the descriptor-lifetime coverage the original provided: - a net.Socket handle is delivered to the ipc callback, and the server only observes the FIN once the receiving process closes the handle, proving the descriptor is real and is not leaked. - a dgram.Socket handle, which parseHandle still does not accept, raises the parse error and releases the descriptor. Also rename Handle::init_owned to init_close_on_complete. It sets close_on_complete and leaves owns_fd false, so the old name read as the opposite of what it did in code where fd ownership decides who closes. --- src/jsc/ipc.rs | 6 +- src/runtime/ipc_host.rs | 2 +- test/js/bun/spawn/spawn.ipc.bun-node.test.ts | 74 ++++++++++++++++---- 3 files changed, 67 insertions(+), 15 deletions(-) diff --git a/src/jsc/ipc.rs b/src/jsc/ipc.rs index 25961c2fc96d..fbb292ee93d0 100644 --- a/src/jsc/ipc.rs +++ b/src/jsc/ipc.rs @@ -684,7 +684,11 @@ impl Handle { } } - pub fn init_owned(fd: Fd, js: JSValue) -> Self { + /// Borrow `fd` for the wire (no dup: `owns_fd` stays false) but close the + /// JS handle once the message completes.

Each cluster worker listens on its own dup of the fd the primary bound, so the first worker succeeded and every worker after it failed with "Failed to listen". libuv sidesteps this by calling listen() before the socket is duplicated and marking the imported copy UV_HANDLE_SHARED_TCP_SOCKET so it never listens again. Classify that one failure as benign instead: listen() is still always attempted, so POSIX behavior (including backlog updates) is unchanged, and the SO_ACCEPTCONN probe only runs to decide whether an error is real. This is race-free where a pre-check was not — two workers can both call listen() and the loser then observes a definitively listening socket. Also replaces the user-facing "TODO case dgram.Socket" error with a real message, and drops a win32 branch in the scheduling-policy selection that did the same thing as its else. Covered by a new test that forks two workers onto one shared handle and asserts the policy actually took, which is the case that had no coverage. --- .claude/skills/verify/SKILL.md | 2 + packages/bun-usockets/src/bsd.c | 17 ++++++ packages/bun-usockets/src/context.c | 7 ++- .../src/internal/networking/bsd.h | 1 + src/js/builtins/Ipc.ts | 2 +- src/js/internal/cluster/primary.ts | 4 +- test/js/bun/spawn/spawn.ipc.bun-node.test.ts | 2 +- test/js/node/cluster.test.ts | 61 +++++++++++++++++-- 8 files changed, 84 insertions(+), 12 deletions(-) diff --git a/.claude/skills/verify/SKILL.md b/.claude/skills/verify/SKILL.md index 7ae2a948bae1..ef2d98d82aa5 100644 --- a/.claude/skills/verify/SKILL.md +++ b/.claude/skills/verify/SKILL.md @@ -25,6 +25,8 @@ For worker/subprocess-shaped changes, spawn a subprocess (still `-e`) so worker ## Gotchas +- `node:cluster` changes can't be driven with `-e`: `cluster.fork()` re-execs `argv[1]`, so workers need a real file on disk.

Main's path builds jsc::SystemError with errno = -(SystemErrno as c_int), which is the UV errno on POSIX but the cross-platform SystemErrno ordinal (-98 for EADDRINUSE) on Windows, not UV_EADDRINUSE (-4091). RoundRobinHandle extracts err.errno, passes it through uvTranslateSysError (no-op for n<=0), and the worker's ExceptionWithHostPort(-98) surfaces 'Unknown system error -98'. Keep the raw listen_rc.int() alongside the bun_sys::Error in ListenPipeError::Sys and use that for jsc::SystemError.errno, matching what the PR's pre-merge out-param carried and what Node reports on err.errno.

Remove kReaderInterest / destroyAbandonedNT. Node has no abandoned-socket concept: a socket whose peer sent data+FIN before a listener attaches sits paused with the bytes buffered; only endReadableNT auto-end()s and only once the buffer is consumed. The test that depended on the force-destroy now drains the server socket so autoDestroy fires the same way Node would. 2. onread deliver loop: re-check self.destroyed and self.isPaused() after every callback (pause()/destroy() inside the callback now stops delivery without returning false, matching libuv's re-check of UV_HANDLE_READING). Call the buffer factory once at init then once after each callback like Node's initSocketHandle + onStreamRead. Drop the Duplex.pause calls on false (Node only readStop()s the handle). Reorder Socket.prototype.resume so the Readable flow tick runs while kOnreadDraining is set. 3. stripTls13CipherNames: return { cipherList, tls13Only } and force minVersion = 'TLSv1.3' at every call site when the TLS 1.2 list is empty and the TLS 1.3 list is not, matching Node's processCiphers. A 'TLS_AES_128_GCM_SHA256'-only config no longer silently re-enables 1.2. 4. Drop SUPPORTED_ECDH_GROUPS. ecdhCurve is not plumbed to native, so the JS allowlist added a hard failure (X448, brainpool, ffdhe3072 all valid in Node) without fidelity. Keep Node's validateString so null still throws ERR_INVALID_ARG_TYPE. Replaced the removed-allowlist test with a type-validation test. --- src/js/node/net.ts | 64 +++++++++++------------ src/js/node/tls.ts | 56 +++++++------------- test/js/node/net/node-net.test.ts | 4 +- test/js/node/tls/node-tls-connect.test.ts | 4 ++ test/js/node/tls/node-tls-context.test.ts | 27 +++++----- 5 files changed, 69 insertions(+), 86 deletions(-) diff --git a/src/js/node/net.ts b/src/js/node/net.ts index 25422cd9da5f..99ad3489e3e6 100644 --- a/src/js/node/net.ts +++ b/src/js/node/net.ts @@ -146,7 +146,6 @@ const ksocket = Symbol("ksocket"); const khandlers = Symbol("khandlers"); const kclosed = Symbol("closed"); const kended = Symbol("ended"); -const kReaderInterest = Symbol("kReaderInterest"); const kpendingSession = Symbol("pendingSession"); const kSNIError = Symbol("kSNIError"); const kALPNError = Symbol("kALPNError"); @@ -615,9 +614,6 @@ function SocketEmitEndNT(self, _err?) { } if (!self[kended]) { finishSocketEnd(self); - if (!self.allowHalfOpen && !self[kReaderInterest]) { - setImmediate(destroyAbandonedNT, self); - } } else if (_err && !self.destroyed) { // An error excluded from the synthesis above (teardown noise, or no // listener attached): nothing more is coming, but the socket still has to @@ -1111,23 +1107,6 @@ function onconnection(err, clientHandle) { if (!pauseOnConnect && !isTLS) { _socket.read(0); } - if (_socket.readableFlowing !== null || _socket.listenerCount("data") > 0 || _socket.listenerCount("readable") > 0) { - _socket[kReaderInterest] = true; - } -} - -function destroyAbandonedNT(self) { - if ( - self.destroyed || - self[kReaderInterest] || - self.readableLength === 0 || - self.readableFlowing !== null || - self.listenerCount("data") > 0 || - self.listenerCount("readable") > 0 - ) { - return; - } - self.destroySoon(); } // TODO: SocketHandlers2 is a bad name but its temporary. reworking the Server in a followup PR @@ -1617,22 +1596,32 @@ function Socket(options?) { const self = this; this[kOnreadTail] = undefined; this[kOnreadDraining] = false; - this[kOnreadBuffer] = onreadBufferIsFn ?

A write-only net.createServer handler whose peer closes (test-http-upgrade-binary, test-http-client-*, test-http-should-keep-alive) now matches Node's flowing=null accept state, and without the force-destroy the only way such a socket can stop holding the loop is for its own unref() to work. - Listener::on_create / on_name_pipe_created activate the accepted socket's poll_ref (same as connect_finish already did for client sockets). on_close and mark_inactive already unref it. - Listener::do_stop drops the listener's poll_ref unconditionally; accepted sockets hold the loop on their own now so the active_connections gate was double-counting. this_value/strong_data stay gated so the JS wrapper is still rooted while connections reference it. This also fixes the inverse: server.unref() alone used to let the process exit under a live, ref'd accepted connection (Node keeps it alive). node-http-connect backpressure test relied on the old auto-resume to drain the target socket's unread request; Node hangs on the same test, so drain it explicitly.

After EOF is delivered, the half-open path sets the poll to WRITABLE-only, but us_poll_change always ORs UV_DISCONNECT back in, and AFD keeps reporting it once signalled. The next DISCONNECT re-added READABLE, recv() re-found the same EOF, the EOF path re-armed WRITABLE+DISCONNECT, and on_end fired once per event-loop iteration per half-open socket. Hidden before onconnection stopped force-resuming accepted sockets (a flowing socket auto-closed and never reached this state); 278 prior node-http2 tests now leave write-only server sockets half-open like Node does, and each one added ~70us per loop turn, timing the 10k-request maxSessionMemory stress test out on windows x64-baseline. Skip the READABLE re-add for POLL_TYPE_SOCKET whose poll no longer includes READABLE (end already delivered). The top-of-branch re-arm drops DISCONNECT, so the socket quiesces at 0 events. SEMI_SOCKET kinds keep the unconditional READABLE (connect uses error/eof from status; listen polls READABLE only). Also: normalizePemKeyOption per-key passphrase resolves with !== undefined (Node honors an explicit null as 'no passphrase for this key'); captured MathMin primordial in net.ts; new KeepAlive tests use the failureDetail pattern instead of asserting stderr empty. --- packages/bun-usockets/src/eventing/libuv.c | 12 ++++++++++++ src/js/node/net.ts | 3 ++- src/js/node/tls.ts | 5 ++++- test/js/node/net/node-net-server.test.ts | 8 +++++--- 4 files changed, 23 insertions(+), 5 deletions(-) diff --git a/packages/bun-usockets/src/eventing/libuv.c b/packages/bun-usockets/src/eventing/libuv.c index 01c3a1932372..6ea4134d9e1a 100644 --- a/packages/bun-usockets/src/eventing/libuv.c +++ b/packages/bun-usockets/src/eventing/libuv.c @@ -126,6 +126,18 @@ static void poll_cb(uv_poll_t *p, int status, int events) { sock->group->loop->data.fin_deferred_count++; } } + } else if (kind == POLL_TYPE_SOCKET && + !(us_poll_events(wp) & LIBUS_SOCKET_READABLE)) { + /* A half-open data socket whose end was already delivered: the EOF path + * moved its poll to WRITABLE-only (loop.c), and us_poll_change re-adds + * UV_DISCONNECT unconditionally, so AFD keeps reporting it.

No test is added that does not pass, and none is flaky — see the note on `stdio-reuse-readable-stdio` below. Neither #31829 nor #31715 adds a single `test-child-process-*` file, so these 13 are what actually pin the behavior to v26.3.0. ## The gaps these tests surfaced ### 1. `process.stdout` leaked `O_NONBLOCK` onto `stdio: "inherit"` children Merely *reading* the `process.stdout` getter switched fd 1 to `O_NONBLOCK`. That flag lives on the **open file description**, shared with every child inheriting the descriptor — so children died on large writes: ``` BlockingIOError: [Errno 35] write could not complete without blocking ``` Bun already intended to prevent this (`BunProcess.cpp` forces stdio sinks synchronous on POSIX), but the undo in `Bun__ForceFileSinkToBeSynchronousForProcessObjectStdio` was gated on `self.fd`, which `FileSink::setup()` never populates — so it silently never ran. Only observable when stdout is a **pipe**; a TTY already took the `isatty` branch. Fixes `test-child-process-set-blocking`. ### 2. `NODE_`-prefixed messages did not emit `internalMessage` Node reserves that `cmd` prefix for channel traffic. Bun recognised only the three `NODE_HANDLE{,_ACK,_NACK}` commands and delivered everything else — including a caller's own `NODE_`-prefixed cmd — as a plain `message`. (Bun's cluster keys off `NODE_UNIQUE_ID` and a separate internal wire flag, so nothing in-tree depended on the old behavior; #31829's cluster suite is 27/27 with this change.) Applies on **both** ends, as Node's `setupChannel()` does: the parent-side `ChildProcess` in `child_process.ts` and the child-side `process` in `Process__emitMessageEvent`. Verified against node v26.3.0 — `NODE_foo` is internal, while `fooNODE_` and a bare `NODE_` stay plain messages. Fixes `test-child-process-internal` (child→parent); the parent→child direction is covered by a case in bun's own suite, since no vendored test exercises it. ### 3. Another subprocess's `.stdin` could not be a stdio target `spawn('cat', { stdio: ['pipe', other.stdin, 'inherit'] })` threw `TODO: stream.Writable stdio`. A subprocess's `.stdin` is a WriteStream over a FileSink: it has no `fd`, but the sink knows the pipe's write end and already exposes `_getFd()`. A Writable also satisfies `isNodeStreamReadable` (both carry `.on`/`.pipe`), so the Readable branch was the one actually taken and the Writable twin was unreachable dead code. Covered by a posix-gated case in bun's own `child_process.test.ts` rather than node's `test-child-process-stdio-merge-stdouts-into-cat`: on Windows the sink hands back a raw HANDLE rather than a descriptor, so there is no fd to pass along and `nodeToBun` still throws. Node carries no Windows guard for that test and vendored tests must stay verbatim, so it is not added. The fix is a no-op on Windows. ### Also `common.isPi` re-synced to v26.3.0's function form; it had been rewritten as an eagerly-evaluated const, so `common.isPi()` threw. ## Verification Each fix was checked against **real node v26.3.0** and an **unmodified canary** as a negative control: | flow | this PR | node v26.3.0 | canary | |---|---|---|---| | `stdio:'inherit'` + 100KB child write, stdout a pipe | `NONBLOCK=False`, exit 0 | same | `NONBLOCK=True`, `BlockingIOError`, exit 120 | Two review concerns were **measured and refuted** rather than accepted: a later `Bun.write(Bun.stdout)` does *not* re-set `O_NONBLOCK`, and making stdout blocking costs nothing (10MB through a slow pipe: 1016ms vs canary's 1034ms, event loop stays live) — POSIX stdio was already force-sync, so this only stops the flag escaping to children. No regressions: `node/cluster` 27/0, `node/child_process`, `node/net`, `node/http`, `node/http2`, `node/stream`, `node/dgram`, `node/process`, `web/websocket` all at parity. (This box is heavily loaded and ~2 timing-sensitive tests flake per full run; counts above are with a retry pass.) ## Remaining - **Socket-list / worker bookkeeping** (2: `fork-getconnections`, `fork-net`) — needs `internal/socket_list`, `server._setupWorker` and `_connections` accounting. (`pass-fd` is now included and passing: because the send path dups the descriptor, the child's copy is independent and Node's sender-detach dance isn't required for it.) - **Readable-direction stdio reuse** (3: `stdio-reuse-readable-stdio`, `pipe-dataflow`, `fork-stdio`). Handing a child's `.stdout` to another child races: bun's subprocess pipe reader starts eagerly, so the parent steals bytes from the second child. A prototype made `stdio-reuse` pass but flaked ~1/3 of runs (node: 6/6 clean), so it was dropped rather than shipped — the invariant is spelled out in `pipe-dataflow`, which asserts `readStart` is never called. Needs bun's stdout buffering to become lazy. `pipe-dataflow` additionally wants node's internal `_handle.readStart`. - **`dgram.Socket` handle passing** (1: `fork-dgram`) — #31829 covers `dgram.Native`, not `dgram.Socket`. - **`send()` backpressure return value** (1: `send-returns-boolean`). Bun's `indicate_backoff` (`waiting_for_ack.is_some() && !queue.is_empty()`) already mirrors Node's `_handleQueue.length === 1`; the test fails only because it sends a raw `server._handle`, which Node classifies as `net.Native` and the serializer drops. `net.Native` has no clean bun equivalent — wants a maintainer's call. - **`node:test` standalone** (1: `windows-hide`) — pre-existing, owned elsewhere. - **`process.channel.fd` on the child side** — `test-child-process-fork-advanced-header-serialization` is vendored and green, but it does not exercise what it was written for. Its child gates the hostile length-header write on `process.channel?.fd`, and Bun's child-side `process.channel` is a `Control` EventEmitter with no `fd` (node reports `fd: 3`, Bun `undefined`), so the write is skipped and only "the children exit 0" is asserted. Counted above because it passes and is byte-identical, but the meaningful figure is 98, not 99. Exposing `fd` is not a one-liner: it would make this test start pushing malformed 4-byte headers into the IPC channel, which the parser then has to survive to keep the test green. - **`O_NONBLOCK` reaching a child that inherits another subprocess's `.stdin`** — an intentionally-excluded site of the same bug class as gap 1 above, newly reachable through this PR's `streamFdOf`. The parent's write end of `p3`'s stdin carries `O_NONBLOCK` so the parent's FileSink can write asynchronously, and the flag rides the `dup2` into the child because it lives on the shared open file description. A child that does not retry on `EAGAIN` therefore fails once its write outgrows the socketpair buffer — verified: `cat` reports `write error: Resource temporarily unavailable` and exits 1, and a `fcntl` probe confirms `NONBLOCK=True` on the child's fd 1. Clearing the flag is not a fix, since the parent shares that description and would start blocking, and `posix_spawn` has no post-fork hook to clear it child-side; a real fix needs the child to get its own description via a blocking relay pipe. Pinned by a `.todo`'d large-write case next to the stdin-as-stdio test in `child_process.test.ts`. The small writes in that test never fill the buffer, which is why it passes. - **Windows fd inheritance for socket/pipe stdio** (2: `stdio-merge-stdouts-into-cat`, `server-close`). Both pass on posix but go red on Windows: a subprocess's stdin sink and a live `net.Socket` both hand back a HANDLE rather than a CRT descriptor `Bun.spawn` can inherit into `CreateProcess`. Node has no Windows guard for either and vendored files must stay verbatim, so neither is added. `stdio-merge`'s behaviour is covered posix-gated in `child_process.test.ts`. --- src/io/lib.rs | 4 + src/js/builtins/BunBuiltinNames.h | 1 + src/js/node/child_process.ts | 68 ++++++-- src/jsc/bindings/BunProcess.cpp | 31 +++- src/jsc/ipc.rs | 21 ++- src/runtime/webcore/FileSink.rs | 17 +- .../node/child_process/child_process.test.ts | 127 ++++++++++++++ test/js/node/test/common/index.js | 6 +- ...ced-serialization-splitted-length-field.js | 24 +++ ...cess-fork-advanced-header-serialization.js | 40 +++++ .../test-child-process-fork-net-server.js | 159 ++++++++++++++++++ .../test-child-process-fork-net-socket.js | 96 +++++++++++ .../parallel/test-child-process-internal.js | 49 ++++++ ...test-child-process-prototype-tampering.mjs | 91 ++++++++++ .../test-child-process-send-keep-open.js | 50 ++++++ .../test-child-process-spawn-args.mjs | 50 ++++++ ...-child-process-spawn-windows-batch-file.js | 97 +++++++++++ ...child-process-spawnsync-non-string-args.js | 7 + .../parallel/test-child-process-uid-gid.js | 20 +++ .../sequential/test-child-process-pass-fd.js | 84 +++++++++ 20 files changed, 1012 insertions(+), 30 deletions(-) create mode 100644 test/js/node/test/parallel/test-child-process-advanced-serialization-splitted-length-field.js create mode 100644 test/js/node/test/parallel/test-child-process-fork-advanced-header-serialization.js create mode 100644 test/js/node/test/parallel/test-child-process-fork-net-server.js create mode 100644 test/js/node/test/parallel/test-child-process-fork-net-socket.js create mode 100644 test/js/node/test/parallel/test-child-process-internal.js create mode 100644 test/js/node/test/parallel/test-child-process-prototype-tampering.mjs create mode 100644 test/js/node/test/parallel/test-child-process-send-keep-open.js create mode 100644 test/js/node/test/parallel/test-child-process-spawn-args.mjs create mode 100644 test/js/node/test/parallel/test-child-process-spawn-windows-batch-file.js create mode 100644 test/js/node/test/parallel/test-child-process-spawnsync-non-string-args.js create mode 100644 test/js/node/test/parallel/test-child-process-uid-gid.js create mode 100644 test/js/node/test/sequential/test-child-process-pass-fd.js diff --git a/src/io/lib.rs b/src/io/lib.rs index f0bbb74f02ec..5ee6de489a2d 100644 --- a/src/io/lib.rs +++ b/src/io/lib.rs @@ -1880,6 +1880,10 @@ impl FilePollRef { self.inner().flags.insert(f); } #[inline] + pub fn unset_flag(self, f: FilePollFlag) { + self.inner().flags.remove(f); + } + #[inline] pub fn file_type(self) -> crate::pipes::FileType { #[cfg(not(windows))] { diff --git a/src/js/builtins/BunBuiltinNames.h b/src/js/builtins/BunBuiltinNames.h index b6495c2eea2b..2d191daa8676 100644 --- a/src/js/builtins/BunBuiltinNames.h +++ b/src/js/builtins/BunBuiltinNames.h @@ -111,6 +111,7 @@ using namespace JSC; macro(ignoreBOM) \ macro(importer) \ macro(inherits) \ + macro(internalMessage) \ macro(internalModuleRegistry) \ macro(internalRequire) \ macro(isAbortSignal) \ diff --git a/src/js/node/child_process.ts b/src/js/node/child_process.ts index 51e8f4455d5d..696b839040d5 100644 --- a/src/js/node/child_process.ts +++ b/src/js/node/child_process.ts @@ -36,7 +36,9 @@ const ArrayPrototypeSplice = Array.prototype.splice; var ArrayBufferIsView = ArrayBuffer.isView; var NumberIsInteger = Number.isInteger; +var ObjectHasOwn = Object.hasOwn; var StringPrototypeIncludes = String.prototype.includes; +var StringPrototypeStartsWith = String.prototype.startsWith; var Uint8ArrayPrototypeIncludes = Uint8Array.prototype.includes; const MAX_BUFFER = 1024 * 1024; @@ -1498,7 +1500,7 @@ class ChildProcess extends EventEmitter { } #emitIpcMessage(message, _, handle) { - this.emit("message", message, handle); + this.emit(isInternalIpcMessage(message) ?

The ERR_OSSL_* codes are composed from BoringSSL's error queue at runtime like Node's error::Decorate, so they are not enumerable in ErrorCode.ts. --- src/jsc/bindings/NodeTLS.cpp | 206 +++++++++++++++-------------------- 1 file changed, 86 insertions(+), 120 deletions(-) diff --git a/src/jsc/bindings/NodeTLS.cpp b/src/jsc/bindings/NodeTLS.cpp index e473b6a99440..220db3cd1ab3 100644 --- a/src/jsc/bindings/NodeTLS.cpp +++ b/src/jsc/bindings/NodeTLS.cpp @@ -2,6 +2,7 @@ #include +#include "JavaScriptCore/IteratorOperations.h" #include "JavaScriptCore/JSArrayBufferView.h" #include "JavaScriptCore/JSObject.h" #include "JavaScriptCore/ObjectConstructor.h" @@ -10,6 +11,8 @@ #include "ZigGlobalObject.h" #include "ErrorCode.h" +#include "node/crypto/CryptoUtil.h" +#include "ncrypto.h" #include "openssl/base.h" #include "openssl/bio.h" #include "openssl/err.h" @@ -141,154 +144,117 @@ static int noPasswordCallback(char*, int, int, void*) return 0; } -struct ClearErrorOnReturn { - ~ClearErrorOnReturn() { ERR_clear_error(); } +// One input slot for the PEM parse pass. `owned` holds the UTF-8 bytes for +// string inputs (CString keeps them alive); for ArrayBufferViews `owned` is +// empty and `bytes` points into the view (kept alive by the +// MarkedArgumentBuffer below). +struct CACertInput { + WTF::CString owned; + std::span bytes; }; JSC_DEFINE_HOST_FUNCTION(parseCACertificates, (JSC::JSGlobalObject * globalObject, JSC::CallFrame* callFrame)) { VM& vm = globalObject->vm(); auto scope = DECLARE_THROW_SCOPE(vm); - ClearErrorOnReturn clearErrorOnReturn; + ncrypto::ClearErrorOnReturn clearErrorOnReturn; - auto* certs = dynamicDowncast(callFrame->argument(0)); - if (!certs) { + JSValue certs = callFrame->argument(0); + if (!certs.isObject()) { return throwVMTypeError(globalObject, scope, "expected an array of certificates"_s); } - JSC::MarkedArgumentBuffer results; - WTF::HashSet seen; - unsigned length = certs->length(); - - for (unsigned i = 0; i < length; i++) { - JSValue element = certs->getIndex(globalObject, i); - RETURN_IF_EXCEPTION(scope, {}); - - WTF::CString utf8; - const void* data = nullptr; - size_t size = 0; + // Pass 1: collect bytes.

Two follow-ups from review on #31829: **Drop `reply["$fd"]` and pass the fd through the handle slot like Node.** Node's `child_process` materializes the received handle and passes it as the second arg to the internalMessage listener, so cluster's `onmessage` / the `_getServer` `send` callback see `(message, handle)`: [utils.js L33-L49](https://github.com/nodejs/node/blob/v26.3.0/lib/internal/cluster/utils.js#L33-L49), [child.js L105-L115](https://github.com/nodejs/node/blob/v26.3.0/lib/internal/cluster/child.js#L105-L115). #31829's implementation wrote the raw fd onto the message object as `"$fd"` and read it back in JS. This PR routes it through the same slot Node uses: - `ipc.rs`: pass the raw fd as the `handle` arg to `handle_ipc_message` instead of `msg_data.put(b"$fd", ...)`. - `InternalMsgHolder.dispatch_unsafe`: forward `handle` to the JS callback instead of `JSValue::NULL`. - `VirtualMachine`/`jsc_hooks`: add `handle` to the `handle_ipc_internal_child` hook signature. - `child.ts`: read `typeof handle === "number"` and wrap via `makeSharedHandle`/`makeConnectionHandle` (same JS-side wrapping as before, just reading the other slot). **Hoist `RoundRobinHandle` constructor closures to bound prototype methods.** The connection listener, accepted-socket close handler, and server `listening` handler become `onServerConnection`/`onAcceptedSocketClose`/`onServerListening` with `.bind(this)` / `.bind(this, handle)`. ### How did you verify your code works? `bun bd` clean on linux. All 85 `test/js/node/test/{parallel,sequential}/test-cluster-*.js` pass, `test/js/node/cluster.test.ts` 26/26 pass. The `$fd` dispatch path is exercised by `test-cluster-message`, `test-cluster-send-deadlock`, `test-cluster-net-send`, the SCHED_NONE shared-handle tests, and every round-robin newconn path. The clippy fix in `node_cluster_binding.rs` is also on the base branch (cb057f546c) so it does not appear in this diff once rebased. --- **no test proof** · iteration 79 · Platform-specific test(s) that do not run on this machine.

Two cluster workers racing on the same shared fd could both call listen(): the first succeeds, the second gets WSAEINVAL, and the benign-error SO_ACCEPTCONN check in us_socket_group_listen_fd can read 0 in the window before the first worker's listen() propagates to the shared kernel object state, so the second worker hard-fails. libuv's fix (UV_HANDLE_SHARED_TCP_SOCKET, win/tcp.c) is to listen in the primary before WSADuplicateSocket; every worker's duplicate is then already listening when it arrives and SO_ACCEPTCONN is reliably set. Match that: call listen() in bsd_create_bound_socket on Windows right after the successful bind. Fixes the intermittent 'EINVAL 10022 listen Failed to listen at' in cluster.test.ts 'SCHED_NONE: a second worker listens on the same shared handle' and 'TLS cluster worker under SCHED_RR listens on a shared handle' on Windows. --- packages/bun-usockets/src/bsd.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/packages/bun-usockets/src/bsd.c b/packages/bun-usockets/src/bsd.c index 69fb81984d4c..0ef96a9eb25c 100644 --- a/packages/bun-usockets/src/bsd.c +++ b/packages/bun-usockets/src/bsd.c @@ -1295,6 +1295,20 @@ LIBUS_SOCKET_DESCRIPTOR bsd_create_bound_socket(const char *host, int port, int if (fd == LIBUS_SOCKET_ERROR) { return LIBUS_SOCKET_ERROR; } +#ifdef _WIN32 + /* Windows rejects listen() on a duplicate of an already-listening socket + * only after another duplicate has listened, so two workers racing on the + * same shared fd can observe listen() -> WSAEINVAL while SO_ACCEPTCONN + * still reads 0 (the benign check in us_socket_group_listen_fd then + * fails). libuv's approach (UV_HANDLE_SHARED_TCP_SOCKET, win/tcp.c) is to + * listen in the primary before WSADuplicateSocket; every worker's + * duplicate is then already listening and SO_ACCEPTCONN is reliably set. */ + if (listen(fd, 511) != 0) { + *error = LIBUS_ERR; + bsd_close_socket(fd); + return LIBUS_SOCKET_ERROR; + } +#endif struct bsd_addr_t tmp; if (bsd_local_addr(fd, &tmp) == 0) { *out_port = bsd_addr_get_port(&tmp); From 39abea91df8900b5dff14eb7f0b6d16d8cfe9ef6 Mon Sep 17 00:00:00 2001 From: robobun <117481402+robobun@users.noreply.github.com> Date: Mon, 3 Aug 2026 18:36:51 +0000 Subject: [PATCH 115/136] trim flagged multi-line comments to single-line refs or drop narration Per comment-cop: kept the Node source URLs as bare single-line links (ciro asked for provenance), shortened correctness notes to one line each, dropped pure narration.

RoundRobinHandle: on kqueue, main now reports a peer RST on a paused socket as an error close. net.ts detaches the native handle on that close but, with no 'error' listener and allowHalfOpen on the primary's accept socket, never destroys the stream, so the queued handle's `fd` getter dereferenced a null handle and the primary died with an uncaught TypeError on the next handoff. Attach a no-op 'error' listener so the close destroys the socket and the existing 'close' eviction runs, make the getter report -1 whenever the handle is gone, and make handoff() skip past dead handles instead of parking the worker in the free list with live connections still queued behind them. onClusterConnection: the connect({fd}) path already schedules read(0) (honoring a pause() made in the handler), mirroring the native accept path since #32630. The extra resume() switched the socket into flowing mode before user code attached listeners, so bytes and EOF that arrived before an asynchronously-attached 'data' listener were emitted to nobody, and a pause() inside the connection handler was undone. Drop it and add a test for the early-bytes shape. --- src/js/internal/cluster/RoundRobinHandle.ts | 49 +++++++++++++-------- src/js/node/net.ts | 3 -- test/js/node/cluster.test.ts | 46 +++++++++++++++++++ 3 files changed, 76 insertions(+), 22 deletions(-) diff --git a/src/js/internal/cluster/RoundRobinHandle.ts b/src/js/internal/cluster/RoundRobinHandle.ts index 6e0023317c74..148b8fe8734a 100644 --- a/src/js/internal/cluster/RoundRobinHandle.ts +++ b/src/js/internal/cluster/RoundRobinHandle.ts @@ -56,6 +56,7 @@ export default class RoundRobinHandle { onServerConnection(socket) { const handle = makeAcceptedHandle(socket); + socket.on("error", noop); socket.once("close", RoundRobinHandle.prototype.onAcceptedSocketClose.bind(this, handle)); this.distribute(0, handle); } @@ -157,42 +158,52 @@ export default class RoundRobinHandle { return; // Worker is closing (or has closed) the server. } - const handle = peek(this.handles); + for (;;) { + const handle = peek(this.handles); - if (handle === null) { - this.free.set(worker.id, worker); // Add to ready queue again. - return; - } + if (handle === null) { + this.free.set(worker.id, worker); // Add to ready queue again. + return; + } - remove(handle); + remove(handle); - const message = { act: "newconn", key: this.key }; + const message = { act: "newconn", key: this.key }; - this.inFlight.set(worker.id, handle); - const sent = sendHelper(worker.process[kHandle], message, handle, reply => { - if (this.inFlight.get(worker.id) !== handle) return; - this.inFlight.delete(worker.id); - if (reply.accepted) handle.close(); - else this.distribute(0, handle); // Worker is shutting down.

This restores the release from fde299e7e4 that was dropped in the 97b68a9f merge repair: the failure paths hand the handle back (adopted cleared, close()), which closes the fd and sends act:close. For the release to work after a close() that already ran during the adoption (socket closed, or the primary closed the handle), the handle's close() is now idempotent at both layers: the protocol release happens once, and the fd is closed by the first close() that sees it unadopted. Test: the primary hands a worker a TCP listening fd, which passes the primary's socket check but fails dgram adoption with EINVAL; once both sides close their copy a connect() to the port is refused, while a leaked copy in either process keeps it accepting. --- src/js/internal/cluster/child.ts | 21 ++++++++------ src/js/node/dgram.ts | 22 ++++++++++---- test/js/node/cluster.test.ts | 50 ++++++++++++++++++++++++++++++++ 3 files changed, 78 insertions(+), 15 deletions(-) diff --git a/src/js/internal/cluster/child.ts b/src/js/internal/cluster/child.ts index 811bb6d04fc5..04dc7c4eca47 100644 --- a/src/js/internal/cluster/child.ts +++ b/src/js/internal/cluster/child.ts @@ -169,16 +169,15 @@ function removeIndexesKey(indexesKey, index) { } function makeSharedHandle(fd) { - let closed = false; + let fdOpen = true; const handle = { sharedFd: fd, adopted: false, close(cb?) { - if (!closed) { - closed = true; - if (!handle.adopted) { - closeRawHandle(fd); - } + // A close() that ran while `adopted` was set leaves the fd to the adopter; a later release (adopted cleared) still closes it. + if (fdOpen && !handle.adopted) { + fdOpen = false; + closeRawHandle(fd); } if (typeof cb === "function") process.nextTick(cb); }, @@ -192,11 +191,15 @@ function shared(message, { handle, indexesKey, index }, cb) { // Monkey-patch the close() method so we can keep track of when it's // closed.

A worker doing close() followed by listen() on the same address therefore raced its own close and got EADDRINUSE from the primary's still-listening copy. Release the shared handle when the listener stops instead. A worker adopting a shared unix fd never learned the path, so address() returned {} (the primary owns the socket file, so the adopted listener must not carry the path natively or it would unlink it on close); keep the path on the server and answer address() from it. cluster_raw_bind bound AF_UNIX names with sizeof(sockaddr_un); for Linux abstract names that registers a NUL-padded 108-byte name that no client using the exact length can reach, so a SCHED_NONE abstract listen reported 'listening' while every connect got ECONNREFUSED. Use the exact length for abstract names, as libuv and uSockets do. us_socket_group_listen_fd reported a poll-registration failure as -poll_rc, which is always 1 (EPERM) on epoll/kqueue; report the errno like the sibling listen paths. process.send()/worker.send() with a tls.TLSSocket silently delivered the message without a handle and reported success; node rejects it with ERR_INVALID_HANDLE_TYPE, and so does the existing branch for non-socket values, so reject it there too. --- packages/bun-usockets/src/context.c | 6 +- src/js/builtins/Ipc.ts | 2 + src/js/node/net.ts | 19 ++- src/runtime/node/node_cluster_binding.rs | 7 +- .../child_process_ipc_handle.test.ts | 44 ++++++- test/js/node/cluster.test.ts | 115 +++++++++++++++++- 6 files changed, 181 insertions(+), 12 deletions(-) diff --git a/packages/bun-usockets/src/context.c b/packages/bun-usockets/src/context.c index 92f4bec316c0..8abb6087bd5e 100644 --- a/packages/bun-usockets/src/context.c +++ b/packages/bun-usockets/src/context.c @@ -433,10 +433,10 @@ struct us_listen_socket_t *us_socket_group_listen_fd(struct us_socket_group_t *g struct us_poll_t *p = us_create_poll(group->loop, 0, sizeof(struct us_listen_socket_t));

The worker may already have adopted it (its ack is lost with the channel, which is exactly what worker.disconnect() tears down), so the same connection could be served by two workers. Close the primary's copy instead, as node does; connections still queued in the primary are unaffected and are still redistributed. The http 'listening' notification called process.send unconditionally, which throws in a process that inherited NODE_UNIQUE_ID without a channel (a helper spawned by a worker) and raises a spurious error after disconnect; skip it when there is no connected channel, as net's path and node's sendHelper do. When the reply carrying a shared handle could not be sent, the worker was told ENOBUFS but stayed registered on the SharedHandle, so the primary kept the address bound and every later listen() by that worker on it failed; unregister it (and drop the handle when it was the last user). Socket.connect() tested the adopted descriptor for truthiness, so a received handle that landed on fd 0 (stdin closed) fell through to the host/port path and threw. The dgram.Native receive branch still read the pre-rename payload field. On channel close, items still queued with a non-zero cursor were completed as if delivered although anything fully written has already left the queue; abort them like the rest. The internal-handle receive path acked a descriptor and then dropped it when the owner had already been torn down; close it. Test fixtures added earlier now close their servers and let the processes exit on their own instead of relying on kill()/process.exit(). --- src/js/builtins/Ipc.ts | 2 +- src/js/internal/cluster/RoundRobinHandle.ts | 4 +- src/js/internal/cluster/primary.ts | 2 + src/js/node/_http_server.ts | 3 +- src/js/node/net.ts | 6 +-- src/runtime/ipc.rs | 20 +++++--- .../child_process_ipc_handle.test.ts | 46 ++++++++++++++++++- test/js/node/cluster.test.ts | 36 +++++++++------ 8 files changed, 89 insertions(+), 30 deletions(-) diff --git a/src/js/builtins/Ipc.ts b/src/js/builtins/Ipc.ts index e4a27db1b4cd..9e9954d1cfbd 100644 --- a/src/js/builtins/Ipc.ts +++ b/src/js/builtins/Ipc.ts @@ -69,7 +69,7 @@ export function parseHandle(target, serialized, fd) { require("node:fs").closeSync(fd); throw new Error(`failed to open received dgram handle: ${err}`); } - emit(target, serialized.message, wrap); + emit(target, serialized.msg, wrap); return; } case "dgram.Socket": { diff --git a/src/js/internal/cluster/RoundRobinHandle.ts b/src/js/internal/cluster/RoundRobinHandle.ts index 148b8fe8734a..435130e8693e 100644 --- a/src/js/internal/cluster/RoundRobinHandle.ts +++ b/src/js/internal/cluster/RoundRobinHandle.ts @@ -120,7 +120,9 @@ export default class RoundRobinHandle { const pending = this.inFlight.get(worker.id); if (pending !== undefined) { this.inFlight.delete(worker.id); - this.distribute(0, pending); + // The worker may already have adopted this connection (its ack is lost with the channel), so + // handing the primary's copy to another worker could serve it twice; drop our copy, as node does. + pending.close(); } if (this.all.size !== 0) return false; diff --git a/src/js/internal/cluster/primary.ts b/src/js/internal/cluster/primary.ts index 194f178678e8..753ed37b99c6 100644 --- a/src/js/internal/cluster/primary.ts +++ b/src/js/internal/cluster/primary.ts @@ -311,6 +311,8 @@ function queryServer(worker, message) { ); if (sent === null && serverHandle !== null && serverHandle !== undefined) { send(worker, { errno: enobufsErrorCode(), key, ack: message.seq, data }, null); + // The worker never got the handle, so it will never send act:close for it. + if (handle.remove(worker) && handles.get(key) === handle) handles.delete(key); } if (cachedHandle && handle !== cachedHandle && !errno) handle.remove(worker); }); diff --git a/src/js/node/_http_server.ts b/src/js/node/_http_server.ts index 1da2252753d9..8f0dc79ec5f7 100644 --- a/src/js/node/_http_server.ts +++ b/src/js/node/_http_server.ts @@ -678,7 +678,8 @@ Server.prototype.listen = function () { address: socketPath ??

Only the channel-gone path touches it now: after a crash the connection goes to another worker, after a graceful disconnect the primary's copy is dropped. The mid-handoff test listened on two port-0 handles, so it never crossed a shared handle; it now does. process.send(msg, socket) left the socket attached in the sender, so the receiver finishing with the connection emitted 'end'/'close' on the sender's object and kept it in the server's connection count; node detaches it at send time. disconnect() closed the channel immediately, discarding messages queued behind a handle still awaiting its ack — including cluster's own act:disconnect — where node postpones the disconnect until that queue is flushed. The primary's fd validation accepted any socket, so a worker's listen({fd: 2}) under a spawned parent (whose stdio is a socketpair) adopted the primary's stderr and closed it on wind-down; node rejects anything that cannot serve with EINVAL and leaves the descriptor alone. Descriptors this code owns (wire dups, received fds, its own bound sockets) are closed even when they were allocated as 0-2, listen_fd no longer flips a descriptor non-blocking before listen() has accepted it, and the http listening hook returns before touching cluster.worker when there is no channel. --- packages/bun-usockets/src/context.c | 6 +- src/js/builtins/Ipc.ts | 11 ++- src/js/internal/cluster/RoundRobinHandle.ts | 27 ++++--- src/js/internal/cluster/primary.ts | 2 +- src/js/node/_http_server.ts | 5 +- src/jsc/bindings/IPC.cpp | 3 +- src/runtime/ipc.rs | 30 +++++--- src/runtime/ipc_host.rs | 3 +- src/runtime/node/node_cluster_binding.rs | 26 +++++-- .../child_process_ipc_handle.test.ts | 51 ++++++++++++++ test/js/node/cluster.test.ts | 70 +++++++++---------- 11 files changed, 169 insertions(+), 65 deletions(-) diff --git a/packages/bun-usockets/src/context.c b/packages/bun-usockets/src/context.c index 8abb6087bd5e..6005f46f7e26 100644 --- a/packages/bun-usockets/src/context.c +++ b/packages/bun-usockets/src/context.c @@ -421,8 +421,8 @@ struct us_listen_socket_t *us_socket_group_listen(struct us_socket_group_t *grou struct us_listen_socket_t *us_socket_group_listen_fd(struct us_socket_group_t *group, unsigned char kind, struct ssl_ctx_st *ssl_ctx, LIBUS_SOCKET_DESCRIPTOR fd, int backlog, int options, int socket_ext_size, int *error) { - apple_no_sigpipe(fd); - bsd_set_nonblocking(fd); + /* Validate with listen(2) before touching the descriptor's flags: on failure the caller keeps + * the fd (it may be its stdio), and a non-socket must come back untouched. */ if (listen(fd, backlog > 0 ? backlog : 512)) { int listen_err = LIBUS_ERR; if (!bsd_socket_listen_error_is_benign(fd)) { @@ -430,6 +430,8 @@ struct us_listen_socket_t *us_socket_group_listen_fd(struct us_socket_group_t *g return 0; } } + apple_no_sigpipe(fd); + bsd_set_nonblocking(fd); struct us_poll_t *p = us_create_poll(group->loop, 0, sizeof(struct us_listen_socket_t)); us_poll_init(p, fd, POLL_TYPE_SEMI_SOCKET); diff --git a/src/js/builtins/Ipc.ts b/src/js/builtins/Ipc.ts index 9e9954d1cfbd..f2130879a958 100644 --- a/src/js/builtins/Ipc.ts +++ b/src/js/builtins/Ipc.ts @@ -12,7 +12,7 @@ * @param {Handle} handle * @returns {[unknown, Serialized] | null} */ -export function serialize(message, handle, _options) { +export function serialize(message, handle, options) { const net = require("node:net"); if (handle instanceof net.Server) { const native = handle._handle; @@ -24,6 +24,15 @@ export function serialize(message, handle, _options) { if (typeof handle[Symbol.for("::buntls::")] === "function") throw $ERR_INVALID_HANDLE_TYPE(); const native = handle._handle; if (!native) return null; + if (!options?.keepOpen) { + // https://github.com/nodejs/node/blob/v26.3.0/lib/internal/child_process.js handleConversion['net.Socket'].send: + // the connection belongs to the receiver from here on; this socket object (and its server's + // connection count) stop tracking it. + if (handle.server) handle.server._connections--; + handle.setTimeout(0); + native.data = undefined; + handle._handle = null; + } return [native, { cmd: "NODE_HANDLE", msg: message, type: "net.Socket" }]; } if (handle instanceof require("node:dgram").Socket) { diff --git a/src/js/internal/cluster/RoundRobinHandle.ts b/src/js/internal/cluster/RoundRobinHandle.ts index 40af56c74c4d..55d5c9a37aff 100644 --- a/src/js/internal/cluster/RoundRobinHandle.ts +++ b/src/js/internal/cluster/RoundRobinHandle.ts @@ -110,22 +110,33 @@ export default class RoundRobinHandle { return this.all.has(worker.id); } - remove(worker) { + // A live act:close leaves an unacked newconn to its ack (the worker redistributes it by declining). + // `channelGone`: no ack is coming.

Only process.disconnect() / child.disconnect() postpone now, connected flips immediately as in node, and any real close cancels the postponement. Because a primary-initiated worker.disconnect() keeps the channel up for exactly that reason, it no longer treats the worker's in-flight connection as unackable; the ack still redistributes a declined connection. A server or dgram handle received right before the channel's EOF was lost: adopting it takes a loop turn, and by then the parent had dropped its ipc callback and the child its channel singleton. Both deliver it now (node does; it still emits before 'disconnect' where we emit after). Also per node: a peer rejected by server.blockList is closed without a 'drop' event; listen({fd}) on a datagram descriptor reports EINVAL rather than the raw EOPNOTSUPP; and when a send fails after serialize() detached the socket, the native handle is closed instead of leaking. --- src/js/internal/cluster/primary.ts | 12 ++-- src/js/node/net.ts | 10 +-- src/runtime/api/bun/subprocess.rs | 8 ++- src/runtime/hw_exports.rs | 2 +- src/runtime/ipc.rs | 26 ++++--- src/runtime/ipc_host.rs | 22 ++++++ src/runtime/socket/Listener.rs | 4 +- .../child_process_ipc_handle.test.ts | 68 +++++++++++++++++-- test/js/node/cluster.test.ts | 18 +++-- test/js/node/net/node-net.test.ts | 30 ++++++++ 10 files changed, 162 insertions(+), 38 deletions(-) diff --git a/src/js/internal/cluster/primary.ts b/src/js/internal/cluster/primary.ts index fb0c7d1bd849..171a168930a1 100644 --- a/src/js/internal/cluster/primary.ts +++ b/src/js/internal/cluster/primary.ts @@ -101,11 +101,13 @@ function removeWorker(worker) { } } -function removeHandlesForWorker(worker) { +// `channelGone`: the worker's channel has closed, so nothing it still holds will be acked.
