v7 What's new

Direct Uploads

Adds support for uploading single files directly (unzipped). Callers can set the new archive parameter to false to skip zipping the file during upload. Right now, we only support single files. The action will fail if the glob passed resolves to multiple files. The name parameter is also ignored with this setting. Instead, the name of the artifact will be the name of the uploaded file.

ESM

To support new versions of the @actions/* packages, we've upgraded the package to ESM.

v6 - What's new

[!IMPORTANT] actions/upload-artifact@v6 now runs on Node.js 24 (runs.using: node24) and requires a minimum Actions Runner version of 2.327.1. If you are using self-hosted runners, ensure they are updated before upgrading.

Node.js 24

This release updates the runtime to Node.js 24. v5 had preliminary support for Node.js 24, however this action was by default still running on Node.js 20. Now this action by default will run on Node.js 24.

Updates actions/download-artifact from 4.3.0 to 8.0.1

Release notes

Sourced from actions/download-artifact's releases.

v8.0.1

What's Changed

Full Changelog: actions/download-artifact@v8...v8.0.1

v8.0.0

v8 - What's new

[!IMPORTANT] actions/download-artifact@v8 has been migrated to an ESM module. This should be transparent to the caller but forks might need to make significant changes.

[!IMPORTANT] Hash mismatches will now error by default. Users can override this behavior with a setting change (see below).

Direct downloads

To support direct uploads in actions/upload-artifact, the action will no longer attempt to unzip all downloaded files. Instead, the action checks the Content-Type header ahead of unzipping and skips non-zipped files. Callers wishing to download a zipped file as-is can also set the new skip-decompress parameter to true.

Enforced checks (breaking)

A previous release introduced digest checks on the download. If a download hash didn't match the expected hash from the server, the action would log a warning. Callers can now configure the behavior on mismatch with the digest-mismatch parameter. To be secure by default, we are now defaulting the behavior to error which will fail the workflow run.

ESM

To support new versions of the @actions/* packages, we've upgraded the package to ESM.

What's Changed

Full Changelog: actions/download-artifact@v7...v8.0.0

v7.0.0

v7 - What's new

[!IMPORTANT] actions/download-artifact@v7 now runs on Node.js 24 (runs.using: node24) and requires a minimum Actions Runner version of 2.327.1. If you are using self-hosted runners, ensure they are updated before upgrading.

Node.js 24

This release updates the runtime to Node.js 24. v6 had preliminary support for Node 24, however this action was by default still running on Node.js 20. Now this action by default will run on Node.js 24.

## Problem

`onUpgrade` in `src/bun.js/api/server.zig` reads
`Sec-WebSocket-Protocol` / `Sec-WebSocket-Extensions` from the user's
upgrade headers via `FetchHeaders.fastGet`, then immediately calls
`fastRemove` on the same entry so the header isn't written twice.

`fastGet` returns a `ZigString` whose pointer borrows directly from the
header map entry's `WTF::StringImpl` buffer (no ref taken). `fastRemove`
erases the map entry, dropping the last reference and freeing that
`StringImpl` when nothing else holds one. The dangling `ZigString` is
then dereferenced later in `toSlice()` and the freed bytes are written
to the socket via `resp.upgrade()`.

Introduced in 12243b9 (#26118).

## Repro

```js
using server = Bun.serve({
  port: 0,
  websocket: { message() {} },
  fetch(req, server) {
    const h = new Headers();
    h.append("Sec-WebSocket-Protocol", "a".repeat(128));
    h.append("Sec-WebSocket-Protocol", "tail"); // map now solely owns the combined StringImpl
    if (server.upgrade(req, { headers: h })) return;
    return new Response("no", { status: 400 });
  },
});
await fetch(server.url, {
  headers: {
    Upgrade: "websocket", Connection: "Upgrade",
    "Sec-WebSocket-Key": "dGhlIHNhbXBsZSBub25jZQ==",
    "Sec-WebSocket-Version": "13", "Sec-WebSocket-Protocol": "x",
  },
});
```

With `Malloc=1` (routes bmalloc through the system allocator) under an
ASAN build:

```
==ERROR: AddressSanitizer: heap-use-after-free
  #6 ZigString.toSlice             src/bun.js/bindings/ZigString.zig:677
  #7 server.onUpgrade              src/bun.js/api/server.zig:1020
```

## Fix

Clone the header value into an owned `ZigString.Slice` via
`toSliceClone` **before** calling `fastRemove`, and point the
`ZigString` at the owned buffer. The owned slice is freed by `defer` at
scope exit, so the later `toSlice()` / `resp.upgrade()` read valid
memory. Applied to both the `Bun.serve` Request path and the `node:http`
upgrade path.

## Verification

- New regression test in
`test/js/bun/websocket/websocket-server.test.ts` double-appends
`Sec-WebSocket-Protocol` so the combined `makeString` result is solely
owned by the header map, and runs the subprocess with `Malloc=1` so ASAN
observes the `StringImpl` allocation.
- `git stash -- src/ && bun bd test <file> -t 'does not use-after-free'`
→ **FAIL** (`AddressSanitizer: heap-use-after-free`)
- `git stash pop && bun bd test <file> -t 'does not use-after-free'` →
**PASS**
- `test/regression/issue/3613.test.ts` (original #26118 fix) still
passes.

…ion getters (#30078)

## Problem

`server.upgrade(req, opts)` reads `Sec-WebSocket-Key` /
`Sec-WebSocket-Protocol` / `Sec-WebSocket-Extensions` from
`request.getFetchHeaders()` via `FetchHeaders.fastGet`, which returns a
`ZigString` that **borrows** directly from the header map entry's
`StringImpl` (`bindings.cpp` `WebCore__FetchHeaders__fastGet_` →
`Zig::toZigString(StringView)`, no ref taken).

It then invokes the `opts.data` / `opts.headers` getters — arbitrary
user JS — and only afterwards passes those borrowed slices to
`resp.upgrade()`.

A getter that mutates `req.headers` (e.g.
`req.headers.set('sec-websocket-key', ...)`) drops the sole ref on the
original `StringImpl` (`HTTPHeaderMap::set` does a `RefPtr` assignment),
freeing it. `resp.upgrade()` then reads freed memory for the
key/protocol/extensions.

```js
Bun.serve({
  fetch(req, server) {
    req.headers; // materialize FetchHeaders
    server.upgrade(req, {
      get data() {
        req.headers.set('sec-websocket-key', 'x'); // frees the borrowed StringImpl
        return undefined;
      },
    });
  },
  websocket: { message() {} },
});
```

The re-entrancy guard after the getters only checks `isAbortedOrEnded()
/ didUpgradeWebSocket()`, not header mutation. The `opts.headers` path
was already defensively cloning with `toSliceClone` (because
`fastRemove` there frees the backing); the `request.headers` path was
missed.

## Fix

Clone `sec_websocket_key` / `protocol` / `extensions` into owned
`ZigString.Slice` storage immediately after reading them from
`request.getFetchHeaders()`, so the bytes stay valid across the option
getters and `resp.upgrade()`. The `opts.headers` override path reuses
the same owned slots (freeing the previous clone first).

## Verification

New test in
`test/js/bun/websocket/websocket-server-upgrade-reentrant.test.ts`
spawns a subprocess with `Malloc=1` (routes bmalloc → system heap so
ASAN observes `StringImpl` frees) and has an `opts.data` getter
overwrite all three `Sec-WebSocket-*` headers.

**Before** (src/ stashed, `bun bd test`):
```
==ERROR: AddressSanitizer: heap-use-after-free
  #3 uWS::HttpResponse<false>::upgrade ... HttpResponse.h:269
  #6 server.zig:1076 (resp.upgrade call)
(fail) server.upgrade() clones Sec-WebSocket-* from request.headers before running option getters
```

**After**: all three tests in the file pass.

Also fails on `USE_SYSTEM_BUN=1` (release, no ASAN) — with `Malloc=1`
the system allocator reuses the freed slot and the WebSocket client
rejects the handshake (bad `Sec-WebSocket-Accept` / mismatched
protocol).

…es (#30077)

## What

When a chunked (or HTTP/3) request body exceeds `maxRequestBodySize`,
`onBufferedBodyChunk` writes the 413 directly on the raw uWS response:

```zig
resp.writeStatus("413 Payload Too Large");
resp.endWithoutBody(comptime !http3);
```

`internalEnd` → `markDone()` nulls `onAborted`, so when the socket
closes no abort ever fires to detach `ctx.resp` or release the base ref.
`this.resp` is left pointing at a completed response whose socket is
about to be freed by `us_internal_free_closed_sockets`.

If the fetch handler returned a pending Promise:

- **resolve**: `handleResolve` → `isAbortedOrEnded()` is false
(`this.resp != null`) → `render()` → `runCorkedWithType` corks the freed
socket → **heap-use-after-free** (ASAN trace below).
- **reject**: `handleReject` reads `resp.hasResponded()` off freed
memory, sees `true`, skips the error handler, and returns without ever
releasing the base ref → **RequestContext leaks**
(`server.pendingRequests` never returns to 0).

## Fix

Route through `this.endWithoutBody()` (the `RequestContext` wrapper)
instead of the raw `resp.endWithoutBody()`. That path does
`detachResponse()` (nulls `this.resp`, clears
`onData`/`onAborted`/`onTimeout`) and `deref()` (releases the base ref),
matching every other end path in this file.

The body promise is rejected with the specific `"Request body exceeded
maxRequestBodySize"` error *before* `endWithoutBody()` so
`endRequestStreaming()` doesn't overwrite it with a generic
`ConnectionClosed`. `has_written_status` is set so any later
`renderMissing`/`renderMetadata` knows the status line is already
committed.

## Repro

```

## Test

`test/js/bun/http/serve-pending-promise-abort-leak.test.ts` — new case
sends a raw `Transfer-Encoding: chunked` POST exceeding
`maxRequestBodySize` with a handler that holds its resolve/reject, waits
for the socket to be reclaimed, then settles the Promise. Asserts
`pendingRequests` returns to 0 for both paths, the body was rejected
with the right message, and a follow-up request still works.

Without the fix: ASAN heap-use-after-free on the resolve path; on
release builds the reject path shows `pendingAfterReject: 1` (leak).

…worker panic, never retry (#30216)

## What

`bun test --isolate` / `--parallel` crashes when a test file loads a
native addon whose deferred napi finalizers outlive the file. The
`--parallel` coordinator then silently retries the file once, which
masks the panic and lets the run exit 0.

Fixes #30205, #30191. Supersedes #30214 (same NapiEnv fix, but without
the coordinator change, the `cleanup_hooks` retarget, or a test that
actually reproduces on unpatched `main`).

## Reproduction

```sh
git clone https://github.com/workglow-dev/libs && cd libs
bun i && bun run build:packages
bun test --timeout=30000 --parallel=4 packages/test/src/test/{util,task}/*.test.ts
```

On `main` (d484fd6), 3–4 workers crash per run with either
```
ASSERTION FAILED: isMarked(cell)
  JavaScriptCore/heap/Heap.cpp:1232 : void JSC::Heap::addToRememberedSet(const JSCell *)
```
or (when the slot is already being reallocated)
```
ASSERTION FAILED: m_cellState == CellState::DefinitelyWhite
  JavaScriptCore/JSCellInlines.h:69 : JSC::JSCell::JSCell(VM &, Structure *)
```
and in release builds the segfaults at `0x68` / `0xD0` reported in
#30205.

## Root cause

Frame-pointer walk from the assertion:

```
#3  Bun::NapiHandleScope::open(Zig::GlobalObject*, bool)
#4  NapiHandleScope__open
#6  napi.Finalizer.run
#7  napi.NapiFinalizerTask.runOnJSThread
#10 event_loop.tick
#11 event_loop.waitForPromise
#13 VirtualMachine.loadEntryPointForTestRunner   ← next test file
```

`NapiEnv::m_globalObject` is a raw `Zig::GlobalObject*`. For
non-experimental addons (`nm_version != NAPI_VERSION_EXPERIMENTAL`,
which is ~every real-world addon — sharp, better-sqlite3, etc.),
`napi_wrap`/`napi_create_external` finalizers are **deferred** to the
event loop as `NapiFinalizerTask` rather than run inside GC sweep.

Objects rooted on the old global (module graph, `globalThis.*`) only
become collectable when `Zig__GlobalObject__createForTestIsolation` runs
`gcUnprotect(oldGlobal)`. The `DeferGC` from #29573 ends at that
function's `}`, so the next GC runs there, collects those objects, and
enqueues their finalizers. Those tasks then run on the very next
`eventLoop().tick()` — inside `loadEntryPointForTestRunner`'s
`waitForPromise` for file N+1. `Finalizer.run` opens a `NapiHandleScope`
via `env->globalObject()`, which reads `NapiHandleScopeImplStructure()`
off the dead cell and writes `m_currentNapiHandleScopeImpl` on it →
write barrier on an unmarked cell.

The `--parallel` coordinator's `reapWorker` then re-queued the file once
(`retries[idx] < 1`) into a fresh worker with no stale `NapiEnv`, which
passed — so the run reported 0 fail despite multiple Bun panics in the
log.

## Fix

**NapiEnv retarget** (`ZigGlobalObject.cpp`, `napi.h`):
`Zig__GlobalObject__createForTestIsolation` now calls
`newGlobal->adoptNapiEnvsForTestIsolation(oldGlobal)` before
`gcUnprotect`. Each `NapiEnv::m_globalObject` is repointed at the new
global and the `Ref<NapiEnv>`s are moved over, so late finalizers open
handle scopes on a live global and the envs stay owned after the old
global is swept. `VirtualMachine.swapGlobalForTestIsolation` also
repoints `rare_data.cleanup_hooks[*].globalThis` so `CleanupHook.eql()`
stays accurate.

**No retry, abort on panic** (`Coordinator.zig`): removed the per-file
retry. A worker that dies mid-file is counted as one failure. If it died
by a fatal signal (SIGILL/SIGTRAP/SIGABRT/SIGBUS/SIGFPE/SIGSEGV/SIGSYS —
Bun's own `@trap()`, a JSC/WTF assertion, or native-addon crash), the
whole run aborts with `error: a test worker process crashed with <SIG>
while running <file>`. `process.exit()` / SIGKILL are still just a
per-file failure and the run continues.

## Verification

- `test/regression/issue/30205.test.ts` — 4 tests. Adds a tiny
non-experimental addon (`isolate_finalizer_addon.c`) and a fixture
pattern (`Bun.gc(true)` + module-scope `await 0` + objects rooted on
`globalThis`) that crashes **8/8** on unpatched `main` and passes 8/8
with this change.
- `workglow-dev/libs` full 201-file unit suite: 3× clean `--parallel=4`
runs (was 3–4 crashes/run).
- Gate: `git stash -- src/ && bun bd test
test/regression/issue/30205.test.ts` → 3/4 fail; with fix → 4/4 pass.
- `test/cli/test/isolation.test.ts`,
`test/regression/issue/29519.test.ts` → pass (one pre-existing unrelated
timeout in isolation.test.ts, same as #29573).
- `test/cli/test/parallel.test.ts` → all tests I touched pass; the 3
timing-sensitive scale-up/work-steal tests that fail in this container
fail identically on unmodified `main`.

…s, http (#30722)

Hardens 36 reachable security findings across the runtime, package
manager, parsers, HTTP client/server, and SQL drivers. Three
auto-applied fixes (#61 SSL exception leak, #68 YAML merge dedup, #104
archive overwrite precheck) were dropped: #61 introduced a
use-after-free, #68 stored a non-`'static` byte view in a `'static`
field, and #104 added dead gating that did not close the traversal.

### Memory safety / lifetime
- #2 — Dangling proxy slice across reentrant JS getter — copy
`process.env` proxy href to an owned `Vec` before reentrant getters can
free the env map (`Blob.rs`)
- #15 — Rollback restores dangling editor name pointer — preserve and
restore `name_storage` on `detect_editor` failure (`BunObject.rs`)
- #81 — Reentrant reconnect frees live handlers — only free previous
handlers when `active_connections == 0` (`Listener.rs`)
- #110 — Async randomFill uses stale resizable buffer pointer — fill a
worker-owned scratch buffer; copy back on the JS thread after
re-validating bounds (`node_crypto_binding.rs`)
- #119 — Null zero-length slice UB in DOMJIT fast path — use
`ffi::slice` which tolerates `(null, 0)` (`Crypto.rs`)
- #67 — Raw serialization reads struct padding bytes — add explicit
`_padding_*` fields with `offset_of!` proof asserts (`npm.rs`)
- #74 — TLS rejection path leaks websocket refcount — route SSL/auth
failures through `self.fail()` which clears `outgoing_websocket`
(`websocket_client.rs`)
- #108 — FD-backed fetch body leaks duplicated descriptor — close
`opened_fd` unconditionally after `read_file` (`fetch.rs`)

### Untrusted-input bounds / panics
- #10 — Invalid lockfile tag causes panic DoS — replace `unreachable!()`
with logged error + `Tag::Uninitialized` (`dependency.rs`)
- #20 — Unchecked lockfile string offsets cause OOB slice — bounds-check
non-inline `String` pointers against `ctx.buffer` (`dependency.rs`)
- #91 — Panic on unvalidated resolution tag — validate `ResolutionTag`
discriminants on lockfile load (`Package.rs`)
- #24 — Unwrap panic on unexpected 304 response — return
`UnexpectedNotModified` when no cached manifest exists (`npm.rs`)
- #44 — UDP port getter unwrap panic on transient state — return
`undefined` when `socket` is `None` (`udp_socket.rs`)
- #36 — Close reason length mismatch causes panic — clamp `body_len` to
125 and bail on overlong UTF-8 transcode (`websocket_client.rs`)
- #100 — Windows pipe name length panic DoS — `debug_assert` → real
bounds check (`Listener.rs`)
- #60 / #111 — Windows shim stack buffer overflows — bounds-check
argument and filename writes against `BUF1_LEN`/`BUF2_U16_LEN` before
`copy_nonoverlapping` (`bun_shim_impl.rs`)
- #76 / #101 — Unchecked bin name/entry name copies — bounds-check
before slicing into `abs_dest_buf` (`bin.rs`)
- #79 — `if` keyword misclassification causes parser panic — require a
delimiter token before classifying (`shell_parser/parse.rs`)
- #32 — Bounds check occurs after UTF-16 write — pre-flight key/value
lengths before `convert_utf8_to_utf16_in_buffer` (`env_loader.rs`)
- #95 — PBKDF2 digest validation allows panic-only algorithm — reject
digests with no `EVP_MD` (`PBKDF2.rs`)

### DoS / resource caps
- #17 — Unbounded recursion on deep TOML dotted keys — cap dotted-key
segments at 512 (`toml.rs`)
- #39 — Unbounded brace expansion preallocation — cap expansion count at
65536 in `Bun.$` and `Bun.braces` (`BunObject.rs`, `Expansion.rs`)
- #31 — SCRAM PBKDF2 parameters accepted from server — clamp iteration
count to `[4096, 10M]`, salt length to `[1, 1024]`
(`PostgresSQLConnection.rs`)

### Auth / injection / traversal
- #19 — Cleartext password sent after TLS downgrade — require
`TLSStatus::SslOk`, not just `ssl_mode != Disable`
(`MySQLConnection.rs`)
- #83 — Strict TLS request reuses lax-verified pooled socket — track
`established_with_reject_unauthorized` and refuse pool reuse for strict
callers (`HTTPContext.rs`, `lib.rs`, `ClientSession.rs`)
- #73 — IPv6 loopback prefix auth bypass — exact-match `::1` instead of
`starts_with` (`server_body.rs`)
- #56 — Unsanitized filename injects response headers — reject
`\r`/`\n`/NUL/`"` in `content-disposition` filenames
(`RequestContext.rs`)
- #43 — Missing CRLF checks for signed host/auth headers — also validate
`region`, `access_key_id`, and `host` (`s3_signing/credentials.rs`)
- #34 — Bucket slash enables S3 host confusion — reject buckets
containing `/` (`s3_signing/credentials.rs`)
- #25 — Lexical symlink check permits extraction escape — track created
symlinks during extraction and refuse paths that traverse them
(`libarchive/lib.rs`)
- #71 — bunx executes untrusted temp-cache binary — `lstat` cached
binary; refuse symlinks and other-uid files (`bunx_command.rs`)

### Permission hygiene
- #6 — Bin target chmod always sets mode 0777 — `0o777 & !umask` instead
of `umask | 0o777` (`bin.rs`)
- #23 — Process umask cleared and never restored — restore umask after
probing it in `ensure_umask` (`bin.rs`)

### Parser correctness
- #22 — Sign-prefixed scalar misparsed as infinity — fix Zig→Rust
`&&`/`||` precedence transliteration (`yaml.rs`)

…er (#31333)

### Problem

Fuzzing found a second transpiler stack overflow
(`sig:SIGSEGV:nostack`): ~600 nested `{` blocks crash the process.

```js
new Bun.Transpiler({ loader: "tsx", target: "bun", minifyWhitespace: true, deadCodeElimination: true })
  .transformSync("{".repeat(600) + 'class Test1 { static "prop1" = 0; }' + "}".repeat(600));
```

#31242 guarded the **expression** recursion (`visit_expr_in_out`,
`print_expr`, DCE helpers), but the **statement** recursion was left
unguarded. Nested blocks stay under `MAX_STMT_DEPTH` (1000) in
`parse_stmt`, then the visit pass recurses through `visit_stmts →
visit_and_append_stmt → s_block → visit_stmts` with no stack check —
each level stacks several multi-KB frames, so a few hundred levels
exhaust the thread's stack (reproduces at depth 800 on a debug build's 8
MB main stack; smaller stacks crash at 600):

```
#5  visit_stmts                 src/js_parser/visit/mod.rs:1280
#6  s_block                     src/js_parser/visit/visit_stmt.rs:1627
#7  visit_and_append_stmt       src/js_parser/visit/visit_stmt.rs:108
#8  visit_stmts                 src/js_parser/visit/mod.rs:1336
... (repeats until SIGSEGV)
```

### Fix

Guard the statement recursion the same way the expression recursion
already is:

- `visit_and_append_stmt` now checks `stack_check.is_safe_to_recurse()`
(plus the `reported_stack_overflow` fast-path) and reports "Maximum call
stack size exceeded" instead of descending, mirroring
`visit_expr_in_out`.
- `print_stmt` and `print_if` (which self-recurses for `else if` chains
without passing through `print_stmt`) get the same guard
`print_expr`/`print_binding` already have, so a deep AST printed on a
thread with less stack headroom errors instead of overflowing.
- Removed the `MAX_STMT_DEPTH`/`parse_stmt_depth` hard cap from
`parse_stmt` (review feedback): recursion depth in every phase is now
governed by `StackCheck` alone, matching the Zig parser.
- Guarded `hoist_symbols` the same way: it walks the scope tree before
the visit pass at the full depth the parser allowed, and was only kept
safe previously by the now-removed cap (the 15k-deep
`lots-of-for-loop.js` fixture overflowed it in release builds
otherwise).

With this, every arbitrarily-nestable AST recursion (statements,
expressions, bindings) is stack-checked in all three phases (parse,
visit, print); deep inputs throw a catchable `Maximum call stack size
exceeded` error.

### Verification

New test `deeply nested statement blocks error instead of crashing the
process` in `test/bundler/transpiler/transpiler.test.js` transpiles
nested-block and `else if`-chain shapes at depths 600/800/990 (below the
parse-time cap, deep enough to overflow an unguarded visitor) in a
subprocess and asserts it exits cleanly.

- Without the fix: the subprocess dies with SIGSEGV at depth 800+ (debug
build), so the test fails.
- With the fix: `bun bd test test/bundler/transpiler/transpiler.test.js`
→ 147 pass, 0 fail; the repro above now throws `Maximum call stack size
exceeded`.

…letes mid-read (#31959) [publish images]

Fixes a use-after-free in the HTTP client's proxy tunnel close path
(Sentry BUN-2VY8, ~10 events/day on Windows release builds; reproduces
deterministically under ASAN on all platforms).

## Repro

`fetch()` through an HTTP CONNECT proxy to an HTTPS origin, where the
origin's final response bytes and its TLS `close_notify` reach the
client in a single TCP batch (origin writes the response and immediately
closes). The regression test builds exactly that: a local CONNECT proxy
that holds origin-to-client bytes after the handshake and flushes
session tickets + response + close_notify in one write.

On an unfixed ASAN build:

```

  HTTPClient::send_progress_update_without_stage_check   src/http/lib.rs:3793
```

## Cause

1. `handle_reading` processes the batch: `SSL_read` returns the body
bytes, the next `SSL_read` hits `close_notify`
(`SSL_ERROR_ZERO_RETURN`), which sets `received_ssl_shutdown` and
`sent_ssl_shutdown` before flushing the already-decrypted bytes through
the data callback.
2. The data callback completes the response. The done path runs
`close_proxy_tunnel(true)` -> `ProxyTunnel::shutdown()` ->
`SSLWrapper::shutdown(true)`, which hits the already-shut-down early
return (`sent_ssl_shutdown || fatal_error`) and returns **without
setting `closed_notified`**. The result callback then frees the
`ThreadlocalAsyncHTTP` embedding the `HTTPClient`, the exact pointer
stored in the wrapper's `handlers.ctx`.
3. Control returns to `handle_reading`. Its liveness guard
(`ssl.is_none() || closed_notified()`) passes because neither is set, so
`trigger_close_callback()` invokes `on_close(handlers.ctx)` on the freed
client. When the allocation has been recycled, `on_close` can ref or
close a different request's tunnel instead of faulting.

## Fix

`src/uws/lib.rs`: when `SSLWrapper::shutdown(fast_shutdown=true)` takes
the already-shut-down early return, fire `trigger_close_callback()`
(idempotent via `closed_notified`) so the wrapper is marked closed
before the owner detaches and frees `handlers.ctx`. A fast shutdown is a
full teardown, and the normal fast-shutdown path already fires the close
callback unconditionally; this only closes the gap where the SSL-level
shutdown had already happened.

Graceful `shutdown(false)` (node:tls half-close via UpgradedDuplex /
WindowsNamedPipe) is unchanged, so reads after a sent `close_notify`
keep working.

## Verification

New test in `test/js/bun/http/proxy.test.ts` (`test.skipIf(!isASAN)`,
the UAF is only deterministic under ASAN): fails on an unfixed ASAN
debug build with the heap-use-after-free above, passes with the fix.
Full `proxy.test.ts` (46 tests) plus `node-tls-connect`,
`node-tls-upgrade`, `node-tls-duplex-close-throw-uaf`,
`node-tls-socket-allow-half-open-option`, `node-tls-server`,
`fetch-tls-cert`, and `node-https-checkServerIdentity` suites pass.

## Note on the asan-lane CI failure (#32144)

The intermittent LeakSanitizer failure on the x64-asan shard (deferred
napi finalizers parked on a never-drained cleanup-hook list at `bun
test` exit) is being fixed in #32146, which carries the same
`global_exit()` drain plus a hooks-only guard that skips pending
`napi_wrap` finalizers on undrained-loop exits. A subset version of that
fix was briefly on this branch (e59bc1d0) but without the hooks-only
guard it made `test/js/third_party/duckdb/duckdb-basic-usage.test.ts`
SEGV at exit on the asan lane (build 62135), exactly the failure mode
#32146's guard prevents, so it was reverted (61f9e701). This PR is
scoped to the proxy-tunnel UAF; its asan lane can still intermittently
hit the pre-existing #32144 leak until #32146 lands.

## Related PRs

- #30606 addresses the same crash signature but patches only the `.zig`
reference files, which are no longer compiled; this PR fixes the
shipping Rust implementation.
- #31952 fixes the same UAF by calling a new `mark_close_notified()`
helper from `ProxyTunnel::shutdown` (silently setting the flag at one
call site, with `close_raw` exempted). This PR instead closes the gap
inside `SSLWrapper::shutdown(true)` itself, so every fast-shutdown
caller (`ProxyTunnel::shutdown`, `ProxyTunnel::close_raw`,
`UpgradedDuplex::close`, `WebSocketProxyTunnel::shutdown`) gets the same
"no callbacks after teardown" guarantee without new wrapper API or a
shutdown/close_raw asymmetry. The close callback is fired rather than
suppressed, so the error teardown path keeps delivering `on_close` ->
`close_and_fail` exactly once (idempotent via `closed_notified`). Test
here is a deterministic single-shot repro (the test proxy reassembles
TLS records and flushes tickets + response + close_notify in one write)
rather than an iteration loop.

…sweep (#32729)

### Crash

```
ASSERTION FAILED: vm().currentThreadIsHoldingAPILock() => vm().heap.mutatorState() != MutatorState::Sweeping
vendor/WebKit/Source/JavaScriptCore/runtime/JSCell.cpp(179) : bool JSC::JSCell::validateIsNotSweeping() const
```

Backtrace (from a release-asan build with asserts):

```
#3  JSC::JSCell::validateIsNotSweeping()
#4  JSC::JSCell::classInfo() const
#5  WTF::uncheckedDowncast<WebCore::JSResumableFetchSink>(JSValue const&)
#6  ResumableFetchSinkPrototype__ondrainSetCachedValue
#7  bun_runtime::webcore::fetch::fetch_tasklet::FetchTasklet::ignore_remaining_response_body
#8  JSC::WeakBlock::sweep()          <- inside GC sweep (Weak finalizer)
#9  JSC::WeakSet::sweep()
#10 JSC::PreciseAllocation::sweep()
#12 JSC::Heap::finalize()
#21 JSC::LocalAllocator::allocateSlowCase
#23 JSC::ErrorInstance::create        <- ordinary allocation kicked off GC
```

Found by the syscall fault-injection fuzzer's client-side grammar
scenario (fetch/node:http with abort + transient errno on the client
socket). Reproduces ~4/5 under `BUN_JSC_collectContinuously=1`.

### Cause

`FetchTasklet::on_response_finalize` is the
`WeakRefOwner<FetchResponse>::finalize` callback and runs inside
`WeakBlock::sweep` while `MutatorState == Sweeping`. When the response
body is `Locked` without a pending promise or stream it calls
`ignore_remaining_response_body()`, which called:

- `ResumableSink::detach_js()`: writes the sink wrapper's cached
`ondrain` / `oncancel` / `stream` slots via the generated
`ResumableFetchSinkPrototype__*SetCachedValue` helpers. Each does
`uncheckedDowncast<JSResumableFetchSink>(thisValue)`, which reaches
`JSCell::classInfo()` and then issues a write barrier on the wrapper
cell.
- `clear_stream_handlers()`: reaches `ReadableStreamTag__tagged` ->
`object->inherits<JSReadableStream>()` (guarded today, but one boolean
away).

Calling `classInfo()` on any cell while the mutator is sweeping is
forbidden: the cell's `Structure` may already have been swept. Assert
builds catch it; release builds corrupt the heap.

### Fix

Thread a `from_finalizer` flag through `ignore_remaining_response_body`.
When `true` (the `on_response_finalize` caller) skip `detach_js()` and
`clear_stream_handlers()`; only native state is touched. The sink's
JS-side detach still happens from `clear_sink()` in
`FetchTasklet::deinit()`, which runs as an event-loop `ConcurrentTask`
outside any sweep, so nothing leaks.

The `on_stream_cancelled_callback` caller (reader `.cancel()`, runs from
JS on the event loop) passes `false` and keeps the immediate detach.

Also corrects the `ResumableSink::detach_js` doc comment that claimed
finalizer safety.

### Verification

New test at `test/js/web/fetch/fetch-response-finalizer-sweep.test.ts`:
a child process under `BUN_JSC_collectContinuously=1` does 12 iterations
of `fetch()` with a user-constructed `ReadableStream` body (so the sink
takes the JS route with a Strong `js_this`) against a raw TCP server
that sends headers + a partial chunked body and never terminates it,
then drops the `Response` unconsumed and runs `Bun.gc(true)`.

Without the fix (`bun bd`, src/ stashed):

```
exitCode: 134
stderr: ASSERTION FAILED: vm().currentThreadIsHoldingAPILock() => vm().heap.mutatorState() != MutatorState::Sweeping
```

With the fix: `stdout: "ok"`, `exitCode: 0`.

`test/js/web/fetch/fetch-backpressure.test.ts` (exercises the
`on_stream_cancelled_callback` path) passes unchanged.

…type (#32738)

### Repro

```js
using listener = Bun.listen({ hostname: "127.0.0.1", port: 0, socket: { data() {} } });
await Bun.connect({
  hostname: "127.0.0.1",
  port: listener.port,
  socket: { open(s) { s.setTypeOfService({}); } },
});
```

On any assert build (debug, release-asan):

```
ASSERTION FAILED: isInt32()
  #4 JSC__JSValue__toInt32
  #5 TCPSocketPrototype__setTypeOfService
  #6 WebCore::TCPSocketPrototype__setTypeOfServiceCallback
```

On plain release the assert compiles out and the NaN-boxed bits of the
object handle are passed to `setsockopt(IP_TOS)` as the TOS byte.

### Cause

`set_type_of_service` in `src/runtime/socket/socket_body.rs` called
`args.ptr[0].to_int32()` on the raw argument. For non-numeric values
that falls through to the C++ `JSC__JSValue__toInt32`, which is
`JSC::JSValue::asInt32()` (the unchecked accessor that asserts
`isInt32()`), not a coercing conversion. The `node:net` wrapper
validates `tos` in JS before calling the handle, but the Bun-native
`Bun.connect` socket exposes this prototype method directly with no JS
validation layer.

### Fix

Route the argument through `validate_integer_range` with `min: 0, max:
255, field_name: "tos"`, the same pattern the sibling `setKeepAlive`
already uses for `initialDelay`. Non-numbers now throw
`ERR_INVALID_ARG_TYPE`, out-of-range integers throw `ERR_OUT_OF_RANGE`,
and non-integral numbers throw `ERR_INVALID_ARG_TYPE`, matching the
`node:net` surface.

I audited the other numeric setters on the TCPSocket/TLSSocket prototype
(`timeout`, `setMaxSendFragment`, `write` offset/length) and the
remaining `to_int32()` / `to_int64()` callers in `src/runtime/socket/`:
each is already gated by `is_number()` / `is_any_int()` or routes
through `coerce`. `setTypeOfService` was the only unguarded one.

### Verification

New test in `test/js/bun/net/socket.test.ts` spawns a subprocess that
calls `setTypeOfService` on a connected `Bun.connect` socket with `{}`,
`"x"`, `-1`, `256`, `1.5`, and `0x10`, and asserts the error code for
each plus that `getTypeOfService()` returns an integer. Without the fix
the subprocess aborts (exit 134) on the first call; with the fix all
seven checks pass. `test/js/node/test/parallel/test-net-socket-tos.js`
continues to pass.

…ed (#33016)

A backend message that fails the connection can share a TCP read with
messages that follow it. `PostgresRequest::on_data`'s message loop had
no bail-out once `fail()` had run, so the trailing messages in that read
kept being dispatched against the already-failed connection.

### Repro

A mock backend that answers the StartupMessage with one write carrying
two messages:

```
R  int32(8) int32(99)   Authentication, unrecognized type
Z  int32(5) 'I'         ReadyForQuery
```

```ts
const sql = new SQL({ url: `postgres://u@127.0.0.1:${port}/db`, max: 1, idleTimeout: 1, connectionTimeout: 5 });
await sql`select 1`.catch(() => {});
await Bun.sleep(1600);
```

### Cause

The unrecognized `Authentication` type calls `fail()`, which sets the
status to `Failed`, closes the socket, and rejects the pending requests,
but the message loop keeps going and dispatches the `ReadyForQuery` from
the same read. That calls `set_status(Status::Connected)`, which has no
guard against leaving `Failed`, so the dead connection is flipped back
to `Connected` and the `on_data` epilogue re-arms its idle timer.
uSockets frees a closed `us_socket_t` at the end of the event-loop
iteration, so when the timer later fires, `ref_and_close` reads the
freed socket:

```

```

### Fix

- `PostgresRequest::on_data`: the message loop returns once the
connection's status is `Failed`. `fail()` is terminal; nothing after it
in the same read should be handled (a `DataRow`, `CommandComplete`, or
`ErrorResponse` in that position would be just as wrong as the
`ReadyForQuery`).
- `PostgresSQLConnection::set_status`: refuses to transition out of
`Failed`. The transition function owns that invariant; every other
consumer of `Status` (the timer interval, `update_has_pending_activity`,
the idempotency check in `fail_with_js_value`) already assumes `Failed`
is terminal.

### Verification

`test/js/sql/postgres-failed-connection-resurrection.test.ts` runs a
fixture against the mock backend above and lets it outlive the
idle-timer window. Without the fix the fixture dies with the ASan report
above; with it the fixture exits 0. Gated to ASan builds because the bug
is a read of freed memory, which release lanes do not detect.

The postgres fault-injection and integration suites still pass locally
(90 tests across `test/js/sql/postgres-*.test.ts`, `sql*.test.ts`,
`tls-sql.test.ts`).

### Related

- #32861 detaches the stored socket handle in `on_close` /
`on_connect_error` so nothing can dereference the freed `us_socket_t`
regardless of how the stale read is reached. It removes the last step of
this chain from the other end; this PR stops the failed connection from
being resurrected at all.
- #30950 guards the JS pool's `handleConnected` against the reverse
ordering within one read (a legitimately queued `onconnect` microtask
arriving after a synchronous `onclose`).

### Repro

```sh
printf '{"name":"x","version":"1.0.0"}' > package.json
bun pm pkg set 'contributors[0]=alice'
```

On a release build (1.4.0 and current `main`) this exits 0 and writes
freed heap bytes into `package.json` as the property key:

```json
{
"name": "x",
"version": "1.0.0",
"P\x01\x00\x00\x00tors": {
  "\x00": "alice"
}
}
```

Depending on what was in the freed allocation the result is often not
valid JSON at all. Any `bun pm pkg set` key path containing `[index]`
hits it.

Under ASAN it is a deterministic `heap-use-after-free`:

### Cause

`parse_key_path` returned a `Vec<Box<[u8]>>`, and `set_value` /
`set_nested` inserted those boxed segments into the manifest AST by
reference: `E::Object::put` constructs `EString::init(key)`, whose
documented contract is that `key` is arena-owned (it records the slice,
it does not copy it). The vector is a local of `set_value`, so it
dropped before `exec_set` reached `save_package_json`, and the JSON
printer then read the dangling keys.

The non-bracket path in `set_value` did not have the bug: it borrowed
its segments straight out of the argv key, which outlives the whole
command. The bracket path differed only by the unnecessary boxing.

### Fix

`parse_key_path` now returns `Vec<&[u8]>`. Every segment is a literal
sub-slice of the input key, so nothing ever needed owning. With the
boxing gone, `set_value`'s separate non-bracket branch and its
`set_nested_simple` helper (which existed only to avoid the allocation)
were exact duplicates of the bracket path, so they are deleted and all
keys route through `parse_key_path` + `set_nested`.

`set_nested_simple`'s trailing `root.put(current_key, nested)` was a
no-op: `ExprData::EObject` is a `StoreRef` handle, so mutating the copy
returned by `root.get()` already mutates the stored object, and the put
re-stores the same handle. Dropping it with the function changes nothing
(and the prior bracket path, `set_nested`, never had it).

Intentionally not changed here: `set 'contributors[0]=alice'` produces
`"contributors": {"0": "alice"}`, an object keyed by the digit string,
rather than the array npm's `pkg set` creates, and `set 'array[]=x'`
still errors with `InvalidPath` instead of appending. Both are the npm
compat gap tracked in #22035, which is separate from the memory safety
of the key names and is not closed by this PR.

### Verification

New test in `test/cli/install/bun-pm-pkg.test.ts` reparses the written
file and asserts the exact object. Without the fix it fails on release
(`SyntaxError: JSON Parse error: Invalid escape character x`) and on the
ASAN debug build (the child aborts on the use-after-free). With the fix
the full `bun-pm-pkg.test.ts` suite passes (74 pass, 0 fail).

### What

After a 3xx redirect, `handle_response_metadata` rewrites per-hop
request state on the HTTP-thread clone of the `AsyncHTTP`:

- `client.url` (and `connected_url`) become a self-borrow into
`client.redirect`, a `Vec<u8>` the clone owns and frees in the
final-callback teardown (`AsyncHTTP::on_async_http_callback_raw`).
- On a cross-origin hop,
`Authorization`/`Proxy-Authorization`/`Cookie`/`Host` are removed from
`client.header_entries` in place.
- The method may be downgraded to GET.

`NetworkTask::notify`'s bitwise copy-back (`ptr::write(real,
ptr::read(async_http))`) carries all of that into the JS-thread
`AsyncHTTP`. When `bun install` retries the task after a retryable
failure (5xx or a connection reset on the redirect target), the
re-scheduled request therefore:

1. connects through the freed redirect buffer (use after free), and
2. if the redirect was cross-origin, goes out without `Authorization`,
so an authorized registry answers 401.

ASAN (debug build), deterministic on the first try:

```
ERROR: AddressSanitizer: heap-use-after-free ... thread T1 (HTTP Client)

previously allocated by thread T1 (HTTP Client):
    <bun_http::HTTPClient>::handle_response_metadata src/http/lib.rs:5038
```

On a release build the same sequence does not crash, but the retries
never reach the server (each one connects through freed memory) and the
install fails.

### Repro

A scripted registry where the manifest URL 302-redirects and the
redirect target answers a 500 once, then the real packument:

```
GET /BaR              -> 302 Location: /redirected/BaR
GET /redirected/BaR   -> 500 on the first hit, then the packument
GET /BaR-0.0.2.tgz    -> tarball
```

`bun install` against it aborts under ASAN and fails on release. Any
301/302/307/308 and 1- or 2-hop chains hit the same path. With an
authorized registry that redirects cross-origin (the common Artifactory
/ CodeArtifact / GitHub Packages shape), the retry also loses
`Authorization`; that variant fails with `GET <registry>/BaR - 401` even
once the URL is fixed.

### Fix

`src/http/AsyncHTTP.rs`: the `!has_more` teardown block already releases
every clone-owned allocation. Before freeing `client.redirect`, restore
the per-hop state that a re-scheduled attempt must not inherit:

- `client.url` back to the caller-owned pre-redirect URL
(`AsyncHTTP.url`, which borrows memory valid for the original's whole
lifetime), and `client.connected_url` (which `connect` derives from it)
to default.
- `client.header_entries` back to the untouched
`AsyncHTTP.request_headers`. The list is bitwise-shared with the
JS-thread original, so it must not be dropped or reallocated on the HTTP
thread; it was cloned from `request_headers` at init and only ever
shrinks, so `clear_retaining_capacity()` +
`append_list_assume_capacity()` restores it in place.
- `client.method` back to `AsyncHTTP.method`.

Nothing that crosses back to the JS thread references clone-freed memory
anymore, and a retried request restarts from the original URL with the
original headers instead of the last redirect hop's, which is what the
install-level retry is meant to do.

### Tests

`test/cli/install/bun-install-retry.test.ts`:
- `retries a manifest whose redirect target 500s once`
- `retries a tarball whose redirect target 500s once` (the sibling retry
site in `runTasks`)
- `retries an authorized manifest whose cross-origin redirect target
500s once` (also asserts the cross-origin hop itself still does NOT
carry `Authorization`, so the spec-mandated strip is unchanged)

All three fail on the unfixed build (ASAN abort under `bun bd`, install
error with `USE_SYSTEM_BUN=1`). The third additionally fails with a 401
if only the URL is restored and not the headers, so each restore is
load-bearing. `test/js/web/fetch/fetch-redirect.test.ts` and
`fetch-url-after-redirect.test.ts` still pass, so `response.url` after a
redirect is unaffected (it comes from the owned `metadata.url` copy, not
from `client.url`).

…ry rewrite (#34271)

`test/js/bun/util/filesystem_router.test.ts` went red on alpine x64 in
build [73276](https://buildkite.com/bun/bun/builds/73276): the `reload()
while Bun.build() resolves the same directory` subprocess segfaulted in
`bust_dir_cache_recursive`, inlined from `NonNull::new`.

## Cause

`RealFS::entries_at` (`src/resolver/lib.rs`) replaces a cached
`DirEntry` in place when the caller's resolver generation is newer than
the cached listing's. The replacement at `*e_ptr = new_entry` drops the
old `DirEntry`, which drops its `data: StringHashMap<*mut Entry>` and
frees the hashmap's bucket allocation. The function's comment says
`entries_mutex held by caller`, but that is only true on one of the five
paths that reach it: `dir_info_uncached`, when entered from
`dir_info_cached_miss`. The other callers (`finalize_result`,
`handle_esm_resolution`, `load_index_with_extension`,
`Transpiler::run_env_loader`) all reach `entries_at` after
`dir_info_cached_maybe_log` has already returned and released both
`RESOLVER_MUTEX` and `entries_mutex`.

`FileSystemRouter::reload()` and `RouteLoader::load` iterate the same
`DirEntry.data` map under `entries_mutex` (the snapshot pattern #33056
introduced for exactly this kind of concurrent rewrite). With
`entries_at`'s rewrite unsynchronized, a `Bun.build()` on the bundler
thread can drop the map while `reload()` on the JS thread is
mid-iteration.

The generation mismatch is what makes `entries_at` enter its rewrite
branch, so the window only opens once the bundle thread has processed at
least one batch (it bumps its own generation after every queue drain);
every subsequent `Bun.build()` then re-reads any directory that
`reload()` just refreshed to generation 0.

ASAN catches it as a heap-use-after-free with the two sides of the race
laid out exactly:

  #21 FileSystemRouter::reload                               src/runtime/api/filesystem_router.rs:492
```

(The use side is sometimes `RouteLoader::load` at
`src/router/lib.rs:816` instead; same map, same lock.)

This has been the shape of `entries_at` since the Rust port; #33056
narrowed the race by snapshotting under the lock but assumed the rewrite
side already held it.

## Fix

`entries_at` now takes `entries_mutex` itself, matching
`read_directory_with_iterator` which already does. The one call path
that reaches it with the lock already held (`dir_info_cached_miss` ->
`dir_info_uncached` -> `parent_.get_entries_ref`) routes through a new
`entries_at_locked` / `get_entries_ref_locked` pair so the non-recursive
mutex is not re-entered. That path is the only one that passes a
non-`None` parent to `dir_info_uncached`; the other caller
(`dir_info_for_resolution`) passes `None`, so the parent branch
containing the accessor never runs there.

## Test

The existing concurrency test now awaits one `Bun.build()` first, so the
bundle thread's generation is already past zero when the concurrent
rounds start, and then runs forty reload/build rounds instead of one.
That is the shape that reaches the stale-generation rewrite at all; the
original single-round fixture usually completes with every build still
on generation 0.

The race is scheduling-dependent. Pinning the fixture to a single core
reproduces the ASAN use-after-free on roughly 3 in 10 runs against an
unpatched debug build and 0 in 15 with this change; with all 16 cores
available the unpatched build reproduces at roughly 1 in 30. The
assertions are otherwise the same as before, so the test continues to
cover the behavior #33056 added.

Also ran the full `filesystem_router.test.ts`,
`test/bundler/bun-build-api.test.ts` (including the thousands-of-builds
test that exercises the generation path heavily),
`test/js/bun/resolve/resolve.test.ts`, `test/cli/hot/hot.test.ts`,
`test/cli/watch/watch.test.ts`, `test/bake/framework-router.test.ts`,
and `bun run rust:check-all` (10/10 targets).

…n worker terminate (#34455)

## What

Fixes a heap-use-after-free when a Worker with an in-flight
`dns.lookup()` / `dns.resolve*()` is terminated.

Surfaced by Node's upstream `test/parallel/test-worker-dns-terminate.js`
(being vendored in #34441), on the debian 13 x64-asan lane:

```

    VirtualMachine::destroy                       src/jsc/VirtualMachine.rs:4453
    WebWorker::shutdown                           src/jsc/web_worker.rs:1299
```

## Repro

```js
const { Worker } = require('worker_threads');
const w = new Worker(`
  const dns = require('dns');
  dns.lookup('nonexistent.org', () => {});
  require('worker_threads').parentPort.postMessage('0');
`, { eval: true });
w.on('message', () => w.terminate());
```

## Cause

`WebWorker::shutdown()` runs, in order: `WebWorker__teardownJSCVM`
(frees the `JSGlobalObject`), then `VirtualMachine::destroy()` which
drops `rare_data` (frees the `FilePoll` hive `Store`) and finally calls
`deinit_runtime_state` which drops `RuntimeState`. That last drop runs
`GlobalData::drop` which calls `ares_destroy()` on the per-VM c-ares
channel.

`ares_destroy()` synchronously fires every pending query callback with
`ARES_EDESTRUCTION` and then the socket-state callback for each fd it
closes. Those callback chains re-enter:

- `Resolver::on_dns_socket_state` -> `FilePoll::deinit_with_vm` on the
already-freed hive slot (the ASAN trace above)
- `GetAddrInfoRequest::on_cares_complete` ->
`DNSLookup::process_get_addr_info` -> `reject_later(global_this)` on the
freed `JSGlobalObject` (bmalloc-backed so ASAN misses it)
- `ResolveInfoRequest::on_cares_complete` -> `request_completed()` ->
`remove_timer()` -> `(*runtime_state()).timer` with the TLS already
nulled (null deref)

## Fix

Add a `RuntimeHooks::close_dns_for_terminate` slot that runs
`Resolver::close_channel_for_terminate()` from `WebWorker::shutdown()`
(and the `BUN_DESTRUCT_VM_ON_EXIT` main-thread path) right after
`close_all_socket_groups`, while JSC, `RareData.file_polls`, the event
loop, and `runtime_state` are all still live. The method also removes
the resolver's c-ares timeout timer, which `GetAddrInfoRequest`'s
EDESTRUCTION path never unwinds. `GlobalData::drop` still handles the
channel if the early hook never ran (it sees `channel == None` when it
did).

This matches Node's model: `Worker::Exit` -> `CleanupHandles()` closes
every handle wrap (including `ChannelWrap`) before disposing the
Isolate.

## Verification

New ASAN-gated test in
`test/js/web/workers/worker-terminate-lifetime.test.ts` spawns four
workers that each start a `dns.lookup()` + `dns.resolve4()` and
terminates them mid-flight.

- **fail-before** (`git stash -- src/ && bun bd test ...`): null-deref
panic / ASAN heap-use-after-free
- **pass-after**: clean exit 0 across 10 consecutive runs

Also verified `test/js/node/dns/` and `test/js/bun/dns/` pass/fail
counts are unchanged vs. main, and `bun run rust:check-all` is clean on
all targets.

```

Reproduced on Linux by looping the file: the h3 subset alone fails about
17 of 100 runs.

## Cause

The ten concurrent h3 tests share one lsquic client engine and one
unconnected UDP socket. `bsd_create_udp_socket()` sets `IP_RECVERR` on
every UDP socket (for `node:dgram`'s error surfacing, #28827), including
QUIC's. When a finished test `proc.kill()`s its server, the client
session is still in the engine and keeps scheduling retransmits /
`NEW_CONNECTION_ID` to an unbound port. With `IP_RECVERR` on, the
resulting ICMP port-unreachable is queued on the shared socket and the
next `sendmmsg` returns `-1 ECONNREFUSED`, even though that call is
sending a datagram to a live peer.

`us_quic_packets_out` reports that as a short return, lsquic clears
`ENPUB_CAN_SEND` for the whole engine and only its one-second
`resume_sending_at` failsafe re-enables it. With several dead sessions
generating ICMPs, every failsafe retry fails the same way and the live
1MB upload never advances; the 20s in CI is two idle-timeout rounds
through `retry_or_fail`.

While tracing that I also found an unsigned underflow in lsquic's
`send_batch` requeue loop: when the first unsent spec in a batch
coalesces multiple packets (`pack_off[0] == 0`, `iovlen > 1`), `end =
&batch->packets[off - 1]` indexes with `UINT_MAX` and only the last
packet of the coalesced group is returned to the connection. The earlier
ones are the INIT ACK and the HSK CRYPTO carrying the client Finished,
so the peer can never complete the handshake. This is the same hang
reached from a different direction (real EAGAIN backpressure instead of
stale ICMP).

## Fix

- `IP_RECVERR` is now opt-in via `LIBUS_UDP_LINUX_RECVERR`, set by
`us_create_udp_socket` when a `recv_error_cb` is provided. `node:dgram`
always passes one and keeps the option; QUIC passes `NULL` and no longer
gets it. This matches libuv's `UV_UDP_LINUX_RECVERR` gating that `bsd.c`
already cited.
- `us_quic_packets_out()` retries once on a non-`EAGAIN`/`ENOBUFS` send
failure before reporting a short return, so a stale `sk_err` that does
surface cannot pause the engine. Both the `sendmmsg` and per-packet
paths now go through `US_FAULT_CHECK(US_FAULT_SENDMSG, ...)` so the
short-return path is reachable from tests.
- `patches/lsquic/requeue-unsent-coalesced.patch` rewrites the requeue
loop's bounds as `[off, off+count)` so every packet in an unsent
coalesced datagram is returned to the connection. The same underflow is
present in upstream lsquic master; I will open a PR there separately.
- `serve-protocols.test.ts` now stops each fixture server gracefully on
stdin close (`server.stop(true)`), matching `serve-http3.test.ts`, so
the pooled client session sees `CONNECTION_CLOSE` instead of leaving the
engine retransmitting to unbound ports.
- `test/js/web/fetch/fetch-http3-syscall-fault.test.ts` injects `EAGAIN`
on the coalesced handshake datagram (the `pack_off[0]==0`, `iovlen>1`
spec the lsquic patch fixes), a one-shot `ECONNREFUSED` that the
retry-once branch consumes, and a burst of `EAGAIN` that the `on_drain`
path recovers from.

## Verification

Release build, looped:

| | before | after |
| --- | --- | --- |
| `serve-protocols -t "http/3"` | 17/100 fail | 2/100 fail |
| `serve-protocols` (full) | 7/100 fail | 4/200 fail |

Debug+ASAN: `serve-protocols`, `serve-http3` (46), `fetch-http3-client`
(52), `fetch-http3-adversarial` (29), `fetch-http3-syscall-fault` (3)
and `dgram.test.ts` all pass, 211 tests total.

The residual ~1-2% is a separate pre-existing bug (the client's 36-byte
HSK CRYPTO is buffered but never flushed when `drain_send_body` writes
the whole 1MB body synchronously from `on_stream_open`); I've handed
that off as its own issue. With CI's retry it is well under the flake
threshold.

### Gate note

The fault-injection hook that makes the new test deterministic lives in
`packages/bun-usockets/src/quic.c`, so `git stash -- src/ packages/`
removes it along with the fix and the fault never fires. The lsquic
piece lives in `patches/` and `scripts/`, which the stash does not
touch. That means a single stashed run passes (no fault, no stall) and a
single unstashed run passes (fault fires, fix handles it), and the gate
cannot distinguish them mechanically. The 300-iteration probe above is
the evidence; the fault-injection tests pin the behavior going forward.

…rier (#36337)

`JSNativeStreamSourceAdapter::m_controller` was a
`JSC::Weak<JSReadableStreamDefaultController>`. When the native pull
promise is rejected (socket fault on a fetch body) the adapter is queued
as the `onNativePullRejected` reaction context, which roots the
**adapter** but not the **controller**: the adapter's only edge to it
was the `Weak`. `FetchTasklet` releases both native `Strong<>`s to the
body stream before that microtask drains, so a GC in between can leave
the entire consumer graph (`controller -> stream -> reader -> pipe op ->
destination -> writer -> readyPromise`) white. The subsequent error
cascade then enqueues the pipe's writes-drained shutdown deferral
against a corpse `op`, and `performPipeShutdownAction(AbortDestination)`
dereferences a swept `readyPromise`:

```
ASSERTION FAILED: result   JSObject.h(583) JSGlobalObject *JSC::JSObject::realm() const
#5  JSC::JSObject::realm()
#6  JSC::JSPromise::rejectPromise
#7  JSC::JSPromise::reject
#8  Bun::WebStreams::writableStreamDefaultWriterEnsureReadyPromiseRejected
#9  Bun::WebStreams::writableStreamStartErroring
#10 Bun::WebStreams::writableStreamAbort
#11 WebCore::performPipeShutdownAction (AbortDestination)
#12 WebCore::JSStreamPipeToOperation::onWritesFinishedForShutdown
```

On builds without the assert the same path is a silent write into
freed/reused promise memory.

## Fix

Hold `m_controller` as a visited internal field so a queued adapter
roots the controller directly. The edge is cleared on every terminal
path (`nativeSourcePullRejected`, `nativeSourceCallClose`,
`nativeSourceCancel`); `controller->algorithmContext` is cleared by
`readableStreamDefaultControllerClearAlgorithms`, so the abandoned case
is an ordinary intra-heap cycle mark-sweep collects.
`NewSource::this_jsvalue` is only `Strong` during FileReader I/O, where
pinning the consumer graph is the correct behavior anyway.

With the `Weak` gone the adapter no longer needs a destructor, so it is
now a `JSInternalFieldObjectImpl<5>`: the five JSValue members (handle,
pendingView, closer, drainValue, controller) are internal fields visited
by the base class, with typed accessors at call sites. The scalar
members (chunkSize, flag bitfield, text-decode state) stay as plain
members.

## Verification

`native-source-onclose-leak.test.ts` (the partial-read + `releaseLock`
abandonment tests for Blob/fetch/File sources) continues to pass,
confirming the cycle does not pin. `streams.test.js`,
`pipeTo-signal-leak.test.ts`, `compression.test.ts`, `blob.test.ts` all
pass.

The crash itself is 0/1800 standalone; it reproduces ~1/3 only under a
fault-injected tracer replay. `pipeTo-shutdown-gc.test.ts` exercises the
shape (native body source, socket fault mid-stream, fire-and-forget
`pipeTo` under `collectContinuously`, `AbortDestination` shutdown arm)
as a regression surface.

…llback (#36986)

## What

`test/js/node/async_hooks/AsyncLocalStorage-tracking.test.ts` (the
crypto-generateKeyPair fixture) fails on every Linux x64-asan run since
#36598 landed (builds
[89023](https://buildkite.com/bun/bun/builds/89023),
[89031](https://buildkite.com/bun/bun/builds/89031)):

```
direct leak of 24b in run (src/runtime/node/node_crypto_binding.rs:85:21) +34 more
SUMMARY: AddressSanitizer: 1480 byte(s) leaked in 35 allocation(s).
  #6 EVP_PKEY_keygen vendor/boringssl/crypto/evp/evp_ctx.cc
  #7 Bun::KeyPairJobCtx::runTask src/jsc/bindings/node/crypto/CryptoGenKeyPair.cpp:23
  #8 Bun__RsaKeyPairJobCtx__runTask src/jsc/bindings/node/crypto/CryptoGenRsaKeyPair.cpp:26
```

## Cause

The 11 extern crypto job ctxs (generateKeyPair x5, sign/verify,
diffieHellman, hkdf, generatePrime, checkPrime, generateKey) completed
by invoking the JS callback from inside C++ `runFromJS` while the ctx
was still alive; the ctx was freed only after `then()` returned. A
callback that never returns (the fixture calls `process.exit(0)` inside
it) stranded everything the ctx still owned: the generated `EVP_PKEY`,
`KeyObjectData` refs, `BIGNUM`s.

The leak is pre-existing; #36598 made it observable by routing
`OPENSSL_malloc` through libc under ASAN. Whether LSan reported the
other job types too was codegen luck (their pointers happened to be
reachable by the conservative stack scan); `generateKeyPair`'s
`EVP_PKEY` sits behind two FastMalloc indirections and was reported
deterministically.

## Fix

Make it structurally impossible for a job ctx to hold native resources
across user JS: the native side never sees the callback.

- `runFromJS` keeps its name (the JS-thread half, paired with the
work-pool half `runTask`) but no longer receives the callback. It
returns `JSCallbackArgs`, a small by-value type whose constructors are
the only producers, so bodies read `return { err };` or `return {
jsNull(), publicKey, privateKey };`. The extern "C" shims copy it
through a typed out-pointer (C linkage cannot return a class type); the
Rust side consumes it as a slice.
- The Rust `extern_crypto_job!` plumbing does, in order: run `runFromJS`
to produce the arguments, free the ctx (`ctx_deinit`), invoke the
callback. The invariant lives in one place and applies to every job
type.
- Shutdown release: a completion task enqueued but not yet dispatched
when `process.exit()` runs (exit racing the work pool) used to be
re-queued at shutdown, stranding the ctx the same way. `AnyTaskJob` now
carries an erased release entry and the shutdown release frees the job
without running its completion. A completion posted after the final
drain is not recoverable without joining the work pool (which would
block exit); `test-crypto-op-during-process-exit.js` stays in
`no-validate-leaksan.txt` for that sliver, now with an accurate comment.
- The caught-export-exception paths encoded the `JSC::Exception` cell
itself, so the callback's err argument was not the thrown Error (not
`instanceof Error`, no `code`). They now use `Exception::value()`,
matching node: JWK export of an unsupported curve surfaces
`ERR_CRYPTO_JWK_UNSUPPORTED_CURVE`.

No behavior change otherwise:

- `Bun__EventLoop__runCallback{1,2,3}` were Rust's
`EventLoop::run_callback` exported to C++. The plumbing now calls
`run_callback` directly: same enter/exit bracketing, same
pending-exception gate, same unhandled-exception reporting, same
synchronous timing. This made `runCallback1`/`runCallback3` dead (the
crypto bodies were their last callers), so their exports and
declarations are deleted; `runCallback2` stays for the webview backends.
- Callback arity is preserved per path (observable via
`arguments.length`): error paths pass 1 arg, results 2, generateKeyPair
success 3.
- Exception paths are preserved: a throw out of argument production
skips the callback and reports unhandled, as before. Each `runFromJS`
checks its `ThrowScope` after every call that can throw
(`RETURN_IF_EXCEPTION`), since the check that used to happen inside the
nested `runCallbackN` call now happens after the C++ scope destructs;
`BUN_JSC_validateExceptionChecks` verifies this on the asan lane.
- The produced `JSValue`s live on the `then()` stack frame between
production and invocation, which JSC's conservative scan covers; they
are JS-heap values, so freeing the ctx first cannot invalidate them.
- Perf: same number of FFI crossings, no allocation added.

The Rust-native crypto jobs (pbkdf2, scrypt, random) already had the
ordering property: they resolve promises or queue the callback via
nextTick, so their ctx drops before user JS runs. The
synchronous-callback extern jobs were the gap.

## Verification

New tests in `crypto.key-objects.test.ts`:

- `isASAN`-gated leak suite: children run with
`BUN_DESTRUCT_VM_ON_EXIT=1` and `detect_leaks=1` (the asan lane's
configuration) and call `process.exit(0)` from the callback of each job
type: generateKeyPair (KeyObject and encrypted PEM outputs), sign,
diffieHellman, hkdf, checkPrime, generateKey, plus an
exit-before-completion-dispatch case (busy-spin so the queued completion
is never dispatched).
- An export-error test: `generateKeyPair('ec', { namedCurve:
'secp224r1', ...jwk encodings })` asserts the callback err is
`instanceof Error` with code `ERR_CRYPTO_JWK_UNSUPPORTED_CURVE` (matches
node; fails on main, which passes the Exception cell).

Results:

- unfixed build (src stashed): both generateKeyPair leak tests fail with
the exact CI signature (`Direct leak of 24 byte(s)` in `EVP_PKEY_keygen`
via `KeyPairJobCtx::runTask`)
- fixed build: all pass, including under
`BUN_JSC_validateExceptionChecks=1`, and ec/ed25519 keypair and verify
probes run leak-clean as well
- `AsyncLocalStorage-tracking.test.ts`: 74 pass, 0 fail (all
async-context crypto fixtures, against both bun and node)
- `crypto.test.ts` (369), `crypto.key-objects.test.ts` (117), and 37
node parallel files (`test-crypto-keygen*`, `test-crypto-sign-verify`,
`test-crypto-hkdf`, `test-crypto-dh-stateless`, `test-crypto-*prime*`)
all pass

The break landed with #36598 (which made the leak visible); #36657
proposed clearing individual ctx fields before the callback, and this PR
supersedes that approach with the ordering guarantee in the job plumbing
instead of per-field resets.
