We have a Use-after-free bug regarding SqliteDatabase::Regulator lifetimes. Specifically, SqlStorage inherits from SqliteDatabase::Regulator, and then passes references to itself into SqliteDatabase calls that construct things, like Statements and Queries. Because SqliteDatabase::Regulator is basically a small logic options class, it might make sense that downstream things only hold a reference to it. Indeed, many uses of SqliteDatabase::Regulator are constexpr. However, in the case of SqlStorage, SqliteDatabase::Regulator is dynamic (SqlStorage). Because the .storage field in JS land is a LAZY_INSTANCE_PROPERTY field, it can be overwritten, and GC can be triggered such that SqlStorage is garbage collected and released, even if there are live SqliteStatement types still using SqlStorage as a Regulator. So, that's a Use-after-Free mistake, and the ASan report agrees with that assessment. So how do we fix it? This approach is to recognize that the Regulator is a bundle of completely static things, and we never have a case where a Regulator has some dynamic policy that can't last the lifetime of the process. So, this change simply requires that all Regulators used by SqliteDatabase are statically allocated, thus eliminating this class of use-after-free. As a consequence, SqlStorage is no longer a Regulator. Also a use-after-free test is added. --- src/workerd/api/sql.c++ | 18 ++++----- src/workerd/api/sql.h | 21 ++++++---- src/workerd/api/tests/sql-test-tail.js | 5 ++- src/workerd/api/tests/sql-test.js | 39 ++++++++++++++++++ src/workerd/util/sqlite-kv.c++ | 3 +- src/workerd/util/sqlite-kv.h | 2 +- src/workerd/util/sqlite-test.c++ | 10 ++--- src/workerd/util/sqlite.c++ | 56 +++++++++++++------------- src/workerd/util/sqlite.h | 53 +++++++++++++++++------- 9 files changed, 137 insertions(+), 70 deletions(-) diff --git a/src/workerd/api/sql.c++ b/src/workerd/api/sql.c++ index d30ca4be6f4..602ece8621c 100644 --- a/src/workerd/api/sql.c++ +++ b/src/workerd/api/sql.c++ @@ -82,9 +82,8 @@ jsg::Ref SqlStorage::exec( // // In theory we could try to cache multiple copies of the statement, but as this is probably // exceedingly rare, it is not worth the added code complexity. - SqliteDatabase::Regulator& regulator = *this;

Fix (two layers of defense) 1. queue.h - ConsumerImpl::read(): Use the existing selfRef weak ref to guard maybeDrainAndSetState(). After handleRead() returns, runIfAlive() checks whether the consumer was destroyed before accessing it. This is defense-in-depth that protects against any path that could destroy the consumer during handleRead. 2. standard.c++ - ByteReadable: Add a reading flag (matching ValueReadable's existing pattern) that prevents cancel() from immediately setting state = kj::none. Instead, cancel() sets pendingCancel = true, and the destruction is deferred until after read() completes. This is the same pattern ValueReadable already uses. --- src/workerd/api/streams/queue.h | 9 +++++- src/workerd/api/streams/standard.c++ | 28 ++++++++++++---- src/workerd/api/tests/BUILD.bazel | 6 ++++ .../api/tests/streams-byte-cancel-uaf-test.js | 32 +++++++++++++++++++ .../streams-byte-cancel-uaf-test.wd-test | 14 ++++++++ src/workerd/api/tests/streams-js-test.js | 22 ++++++++++--- 6 files changed, 100 insertions(+), 11 deletions(-) create mode 100644 src/workerd/api/tests/streams-byte-cancel-uaf-test.js create mode 100644 src/workerd/api/tests/streams-byte-cancel-uaf-test.wd-test diff --git a/src/workerd/api/streams/queue.h b/src/workerd/api/streams/queue.h index dbd0d4f10e7..2b3bf466524 100644 --- a/src/workerd/api/streams/queue.h +++ b/src/workerd/api/streams/queue.h @@ -467,8 +467,15 @@ class ConsumerImpl final { js.v8Isolate, js.typeError("Cannot call read while there is a pending draining read"_kj)); return request.reject(js, error); } + // handleRead may trigger the pull callback (via onConsumerWantsData), which + // may synchronously call reader.cancel().

charset=UTF-8 Content-Transfer-Encoding: 8bit The inner jsg::Promise::then() continuation in WorkerLoader::get() at worker-loader.c++:71 captured IoContext by raw C++ reference (&ioctx) into a V8-heap-rooted promise reaction whose lifetime is decoupled from the IoContext. When the originating IoContext was destroyed before the user's getCode() promise resolved, and the promise was later resolved from a different IoContext on the same isolate (possible when handle_cross_request_promise_resolution is disabled), the lambda would dereference freed memory through toDynamicWorkerSource() → getIoChannelFactory() → getCurrentIncomingRequest(), leading to a heap use-after-free with a virtual call through pointers derived from the freed 712-byte IoContext allocation. The fix replaces the raw [&ioctx] capture with a kj::Own obtained via ioctx.getWeakRef(). The inner lambda now calls weakIoctx->tryGet() and throws a clean JS error ("The request which initiated this dynamic worker load has already completed.") if the IoContext has been destroyed, converting the UAF into a safe, catchable exception regardless of the handle_cross_request_promise_resolution setting. The outer makeReentryCallback wrapper already uses getWeakRef() for its own guard, but the inner .then() lambda bypassed that safety by capturing &ioctx directly. The regression test (regressionDeadIoContextGetCode) exercises the patched code path by making a sub-request that calls env.loader.get() with a pending getCode promise, returning to drain the sub-request's IoContext, then resolving the promise from the test's IoContext. Post-patch, the WeakRef check fires and the clean error message is logged; pre-patch, the UAF would silently dereference freed memory (observable as a crash under ASAN).

The wrapper holds a jsg::Function writeCallback that captures the JS handle (see internal_zlib_base.ts), forming a JS<->C++ reference cycle. Without a visitForGc, V8 cannot trace through the C++->JS edge, so the cycle is uncollectable and every CompressionStream becomes immortal. Reproducer: 20k iterations of inflateSync(input, { info: true }) leaks ~128 MB. Adds visitForGc() to CompressionStream covering writeCallback, writeResult, and errorHandler.

The fast path (zlibUtil.zlibSync) is unaffected: it does the whole compression in C++ without exposing a CompressionStream wrapper to JS.

An attacker-supplied chain of ~1M nested `new Proxy(prev, {})` wrappers drove unbounded native C++ recursion, overrunning the stack guard page and crashing the workerd process with SIGSEGV. This affected all callers: processEntrypointClass, collectMethodsFromPrototypeChain, and RPC paths. The fix replaces the self-recursion with an iterative loop and a hard depth limit of 100,000 (matching V8's internal JSProxy::kMaxIterationLimit), throwing a RangeError when exceeded. The regression test in jsvalue-test.c++ creates a 200,000-deep Proxy chain and calls checkProxyPrototype(), asserting that a RangeError is thrown instead of crashing. AUTOVULN-CLOUDFLARE-WORKERD-143.

The first check, jsg-visit-for-gc, flags JSG resource types whose visitable fields (jsg::Ref, jsg::JsRef, jsg::V8Ref, jsg::Function, jsg::Promise, jsg::BufferSource, jsg::Value, jsg::Data, plus kj::Maybe/Array/Vector/OneOf and jsg::Optional/LenientOptional wrappers thereof) are missing from their visitForGc method. Detection strategy: - Match every concrete record definition in the TU. - For records that have a visitForGc body visible in this TU, check that every visitable field appears in the body via a MemberExpr chain. - For records lacking visitForGc, diagnose when either (a) the record participates in JSG visitation through a base class (e.g., jsg::Object whose empty default would silently miss fields), or (b) the record is used as a field of another record AND some holder's visitForGc body is visible in this TU and authoritative about coverage. Other TUs that include the header but not the holder's defining .c++ defer. - A nested struct's visitable field is suppressed when an enclosing record's visitForGc body reaches it via a MemberExpr chain (e.g., visitor.visit(state.func) covers State::func from NativeHandler's body), avoiding false positives on struct-as-field plus reach-through. The check fires only when the primary translation unit is an implementation file (.c++/.cc/.cpp/.c); header-only passes are silently skipped to avoid false 'no body' diagnostics when visitForGc is defined out-of-line in a sibling .c++ that this header pass cannot observe. Each header gets walked from every .c++ that includes it, so coverage is preserved. The plugin loads dynamically via clang-tidy --load=. This requires the clang-tidy binary to be built with LLVM_ENABLE_PLUGINS=ON, CLANG_PLUGIN_SUPPORT=ON, and LLVM_ENABLE_RTTI=ON, which is the configuration of cloudflare/workerd-tools clang-tidy-22.1.5 (the first release shipping a headers tarball asset alongside the binary). This commit bumps build_deps.jsonc clang_tidy_* entries from clang-tidy-22.1.1 to clang-tidy-22.1.5 and adds clang_tidy_dev_* entries pointing at the headers tarballs. A small fix to build/deps/update-deps.py is included: archive_type detection emitted type="xz" for .tar.xz URLs, which bazel's http_archive does not accept; this is corrected to type="tar.xz". Fields that intentionally opt out of GC tracing can suppress the diagnostic with NOLINT(jsg-visit-for-gc) and a comment explaining the chosen memory model. The newer clang-tidy also enables readability-redundant-typename which fires a false positive in src/workerd/jsg/meta.h on a typename-qualified member of an alias template; that occurrence is now NOLINT-ed with an explanation.

Without visitation the retained handles are never transitioned to weak references and the JS objects they wrap cannot be reclaimed even when no JS code can reach them, causing memory leaks for the lifetime of the isolate. Surfaced and fixed by the jsg-visit-for-gc check introduced in the preceding commit: - EventTarget::maybeListenerCallback (jsg::Function listener-change callback) - EventSource::onopenValue, onmessageValue, onerrorValue (JsRef event handlers) - ExecutionContext::exports (JsRef module exports) - ServiceWorkerGlobalScope::processValue, bufferValue, defaultFetcher - CommonJsModuleObject::exports (JsRef) - CommonJsModuleContext::module (Ref), exports (JsRef) (re-derives AUTOVULN-CLOUDFLARE-WORKERD-42 from first principles) - DurableObjectStorage::maybePrimary (Maybe>) - ActorState::transient (Maybe), persistent (Maybe>) - DurableObjectState::exports, props (JsRef), storage, container (Maybe) - MessageChannel::port1, port2 (Ref) - MessagePort::state (OneOf with Vector in Pending arm), onmessageValue - CustomEvent::detail (Optional) - WritableStreamInternalController::maybeClosureWaitable (Maybe) - WritableStreamDefaultWriter::readyPromisePending (Maybe) - AllReader::parts (Vector intermediate buffers) - CacheStorage::default_ (Ref) - X509Certificate::issuerCert_ (Maybe> cert chain) - LoopbackDurableObjectNamespace::loopbackClass (Ref) - LoopbackColoLocalActorNamespace::loopbackClass (Ref) - PerformanceMark::detail, PerformanceMeasure::detail (Optional) - Performance::entries (Vector>) - SqlStorage::Statement::sqlStorage (Ref), query (V8Ref) - SyncKvStorage::storage (Ref) - TraceItem::eventInfo (Maybe ...>>), logs, exceptions, diagnosticChannelEvents (Array) - FetchEventInfo::request (Ref), response (Optional>) - TailEventInfo::consumedEvents (Array>) - HibernatableWebSocketEventInfo::eventType (OneOf>) - TraceLog::message (V8Ref) - R2Bucket::HeadResult::checksums (Ref) - R2Bucket::GetResult::body (Ref) - node async-hooks AsyncLocalStorage::defaultValue (Maybe) - node crypto CipherHandle::key, AeadHandle::key (Ref) - node util.MimeType::params (Ref) CompressionStream::{writeCallback, writeResult, errorHandler} was already fixed by the preceding zlib-specific commit on this branch. Two intentional non-visits are documented with NOLINT comments: - ByteQueue::Entry::store (jsg::BufferSource): Entry is owned via kj::Rc (C++ refcount) and is not reachable from JS, so the strong v8::Global inside the BufferSource is sufficient to keep it alive without participating in GC tracing. - diagnostics-channel Channel::name (jsg::Name): jsg::Name's visitForGc is private and visitation happens through NameWrapper, not GcVisitor::visit(). --- src/workerd/api/actor-state.h | 12 ++++++ src/workerd/api/basics.c++ | 1 + src/workerd/api/basics.h | 4 ++ src/workerd/api/cache.h | 4 ++ src/workerd/api/commonjs.h | 8 ++++ src/workerd/api/crypto/x509.h | 4 ++ src/workerd/api/eventsource.c++ | 2 +- src/workerd/api/export-loopback.h | 8 ++++ src/workerd/api/global-scope.h | 5 +++ src/workerd/api/messagechannel.h | 11 ++++++ src/workerd/api/node/async-hooks.h | 4 ++ src/workerd/api/node/crypto.h | 8 ++++ src/workerd/api/node/diagnostics-channel.c++ | 3 ++ src/workerd/api/node/diagnostics-channel.h | 5 ++- src/workerd/api/node/util.h | 4 ++ src/workerd/api/performance.h | 12 ++++++ src/workerd/api/r2-bucket.h | 9 +++++ src/workerd/api/sql.h | 4 ++ src/workerd/api/streams/internal.c++ | 1 + src/workerd/api/streams/queue.h | 8 +++- src/workerd/api/streams/standard.c++ | 5 +++ src/workerd/api/streams/writable.c++ | 2 +- src/workerd/api/sync-kv.h | 4 ++ src/workerd/api/trace.h | 40 ++++++++++++++++++++ 24 files changed, 164 insertions(+), 4 deletions(-) diff --git a/src/workerd/api/actor-state.h b/src/workerd/api/actor-state.h index a2cc488a708..67be1b4e968 100644 --- a/src/workerd/api/actor-state.h +++ b/src/workerd/api/actor-state.h @@ -357,6 +357,10 @@ class DurableObjectStorage: public jsg::Object, public DurableObjectStorageOpera // Set if this is a replica Durable Object. kj::Maybe> maybePrimary;

This allowed R2 writeHttpMetadata() — which calls setCommon() with user-controlled metadata fields (contentType, contentDisposition, contentEncoding, contentLanguage, cacheControl) — to insert invalid header bytes into a Headers object, bypassing the TypeError that Headers.set() would throw. The fix adds the same normalizeHeaderValue() call to setCommon() that Headers.set() already uses. The new regression test (r2-write-http-metadata-validation-test) exercises the R2 writeHttpMetadata path with CRLF and NUL payloads in httpMetadata fields, asserting that TypeError is thrown for invalid values while valid metadata continues to work.

V8's promise resolution performs Get(resolution, "then"), which can invoke a user-installed Object.prototype.then getter. A malicious getter can call reader.cancel(), which frees the ConsumerImpl (via ByteReadable::cancel() → state = kj::none) while handleMaybeClose / maybeDrainAndSetState still hold dangling references. After resolve() returns, the code accesses freed memory — a deterministic heap-use-after-free. The fix takes a selfRef.addRef() weak reference before calling handleMaybeClose in maybeDrainAndSetState's close path, and checks liveness after it returns. Inside handleMaybeClose itself, liveness checks are added after each request->resolve(js) call and in the outer while loop condition, so the function bails out immediately if the consumer was freed by re-entrant JavaScript. The new test (streams-byob-close-reentry-test) exercises the exact attack path from AUTOVULN-CLOUDFLARE-WORKERD-198: a byte ReadableStream with a pending BYOB read ({min:10}), 5 buffered bytes, an Object.prototype.then getter that calls reader.cancel(), and controller.close(). The UAF is deterministic under ASAN but silent in non-ASAN builds (freed memory still contains valid-looking data), so the pre-patch test also passes in this non-ASAN environment. Under ASAN/CI the test would crash pre-patch at the OneOf tag read in ConsumerImpl::size(); the fix ensures the code detects the freed consumer and returns safely.

This empty handle then reached KJ_ASSERT(!value.IsEmpty()) in compileGlobals(), aborting the process with a fatal assertion. The fix replaces KJ_LOG(ERROR, ...) with KJ_FAIL_REQUIRE(...) which throws a catchable kj::Exception, allowing the server to report a recoverable configuration error instead of crashing. The regression test in server-test.c++ configures a wrapped binding with a non-existent module name ("nonexistent:missing-module") and verifies that the server produces a config error rather than aborting.

This enabled SSRF: an attacker who controlled the Host header could redirect the Worker's outbound request to an arbitrary host (e.g. 169.254.169.254) while the application believed it was connecting to a validated hostname. The fix changes the URL construction to always use `this.host` (the transport destination from options.hostname/options.host), matching Node.js semantics where the Host header is an HTTP header, not a routing directive. The regression test (testHostHeaderDoesNotOverrideTransportDestination) sends a request with hostname pointing to the sidecar but a Host header set to 169.254.169.254, then verifies the request reaches the sidecar and the echoed Host header does not contain the attacker-supplied value.

When the write promise was canceled (e.g. via removeSink() destroying the Canceler during RPC serialization, or via AbortSignal-triggered pipeTo cancellation), the backing kj::Array was freed but the WriteRequest remained in the state machine with a dangling bytes pointer. A subsequent BYOB read would memmove from freed heap memory into a JS-visible Uint8Array — a heap use-after-free read that leaks attacker-sized chunks of process heap to JavaScript. The symmetric writeHelper() already had this guard for ReadRequest since the code was written; the WriteRequest branch was overlooked. This patch adds the missing fulfiller->isWaiting() check and transitions to a DISCONNECTED error state when the write was canceled, mirroring the existing pattern in writeHelper(). The WriteRequest struct also gains the same WARNING comment that ReadRequest already has. The regression test (identity-transform-stream-uaf-test) exercises the cancellation path via CompressionStream.pipeTo(IdentityTransformStream) with an AbortSignal and preventAbort:true. Pre-patch, reader.read() resolves successfully by reading freed memory; post-patch, it rejects with a disconnected error. AUTOVULN-CLOUDFLARE-WORKERD-156.

When handleFallbackFailure() shipped that callback cross-thread to a different isolate's IoContext via CrossThreadPromiseFulfiller, the callback still referenced the originating Use. If the originating Use/MemoryCache was destroyed (isolate eviction, LRU, worker-set replacement) before the receiving isolate invoked the callback, the callback would dereference freed memory through the dangling `this->cache` pointer — a native UAF outside the V8 sandbox. The fix captures kj::atomicAddRef(*cache) instead of bare `this` in both lambdas, and introduces static helper methods (prepareFallback, handleFallbackFailure) on SharedMemoryCache that take an explicit cache reference. Since prepareFallback/handleFallbackFailure only ever accessed this->cache (the AtomicRefcounted SharedMemoryCache), no Use-specific state is needed, and the callback's lifetime now depends only on the process-wide SharedMemoryCache which every Use already pins. --- src/workerd/api/BUILD.bazel | 9 +++ src/workerd/api/memory-cache-test.c++ | 75 +++++++++++++++++++++++ src/workerd/api/memory-cache.c++ | 87 ++++++++++++++------------- src/workerd/api/memory-cache.h | 4 ++ 4 files changed, 132 insertions(+), 43 deletions(-) create mode 100644 src/workerd/api/memory-cache-test.c++ diff --git a/src/workerd/api/BUILD.bazel b/src/workerd/api/BUILD.bazel index f04560dec53..39964a3d067 100644 --- a/src/workerd/api/BUILD.bazel +++ b/src/workerd/api/BUILD.bazel @@ -568,6 +568,15 @@ kj_test( ], ) +kj_test( + src = "memory-cache-test.c++", + deps = [ + ":memory-cache", + "//src/workerd/io", + "//src/workerd/io:trace", + ], +) + kj_test( src = "streams/internal-test.c++", deps = [ diff --git a/src/workerd/api/memory-cache-test.c++ b/src/workerd/api/memory-cache-test.c++ new file mode 100644 index 00000000000..6d2947e80fc --- /dev/null +++ b/src/workerd/api/memory-cache-test.c++ @@ -0,0 +1,75 @@ +// Regression test: a FallbackDoneCallback returned by getWithFallback() must +// remain safe to invoke even after the SharedMemoryCache::Use that created it +// has been destroyed.

This meant any Worker using DataView-backed key material with createSecretKey() would get an empty SecretKeyObject while the call reported success, undermining HMAC, symmetric encryption, or other key-dependent security logic. The fix changes the copy to use `Buffer.from(key.buffer, key.byteOffset, key.byteLength)`, which correctly handles all ArrayBufferView types including DataView by explicitly referencing the backing buffer, offset, and length. The regression test in crypto_keys-test.js creates secret keys from both a full DataView and a sub-range DataView, verifying that the exported key material matches the original bytes and has the correct length. It also confirms equivalence with a Buffer-created key over the same bytes.

V8's promise resolution performs a Get(resolution, "then") thenable check which can synchronously invoke a user-defined Object.prototype.then getter. That getter can call controller.error(), transitioning the ConsumerImpl from Ready to Errored and freeing the Ready storage. After resolve() returns, the while loop's state.readRequests.empty() check is a use-after-free on the freed Ready storage. The same class of bug existed in ByobRequest::respond() where consumer.push() was called after consumer.resolveRead() without checking whether the consumer was still alive. The fix takes a weak ref (consumer.selfRef) before the resolve call and checks isValid() + state.isActive() after it returns, bailing out of the loop if the consumer was destroyed or its state transitioned. The same pattern is applied to ByobRequest::respond() for the consumer.push() call after resolveRead(). Both ValueQueue::handlePush and ByteQueue::handlePush signatures are updated to accept ConsumerImpl& so they can access the weak ref. The regression test installs an Object.prototype.then getter that calls controller.error() during BYOB read resolution via enqueue(), exercising the exact re-entrant destruction path. Under ASAN this would crash pre-fix; the test verifies the runtime does not assert/crash and the read resolves correctly.

When the handler promise resolved, the caller freed the underlying AsyncIoStreamWithGuards while the JS Socket still held a dangling raw pointer via NeuterableIoStreamImpl::inner. Any subsequent write from a ctx.waitUntil() task triggered a use-after-free (SIGSEGV in NeuterableIoStreamImpl::write). The fix mirrors the request() path: make NeuterableIoStream refcounted (like NeuterableInputStream already is), retain a second reference via kj::addRef, and attach a kj::defer that calls neuter(CLIENT_DISCONNECTED) when the connect handler's promise settles. A KJ_ON_SCOPE_FAILURE guard also neuters on exception. This ensures any post-settlement JS-side I/O on the stashed Socket throws a clean "client disconnected" error instead of dereferencing freed memory. The regression test (connect-neuter-test) exercises the exact attack path: a connect handler stashes a writer, returns immediately, then a ctx.waitUntil() task attempts to write after the caller has freed the stream. Pre-patch, this crashes with SIGSEGV in NeuterableIoStreamImpl::write; post-patch, the write rejects with a disconnected error. AUTOVULN-CLOUDFLARE-WORKERD-334.

For resizable ArrayBuffers, the caller can shrink the buffer via resize(0) after load() returns but before the child isolate's deferred compilation runs, causing compileDataGlobal()'s memcpy to read PROT_NONE pages and SIGSEGV the entire workerd process (cross-tenant DoS). The fix copies the byte arrays via kj::heapArray() at the async boundary in extractSource(), following the JSG rule documented in value.h:981-982 for kj::Array parameters consumed asynchronously. The new regression test (worker-loader-rab-test) creates resizable ArrayBuffers for both data and wasm module types, passes them to env.loader.load(), immediately resizes them to zero, then exercises the child worker. Pre-patch this SIGSEGVs; post-patch the copied bytes survive and the child worker compiles and runs normally.

In #onFinish, `new URL(this.path, baseUrl)` resolved these by replacing the base URL authority with the path-supplied host, causing the outbound fetch to target an attacker-controlled destination instead of the configured hostname. This enabled SSRF when a Worker forwarded user-controlled path data to a fixed upstream via node:http. The fix adds validation in the constructor (alongside the existing INVALID_PATH_REGEX check) to reject paths matching a URI scheme prefix (`/^[a-zA-Z][a-zA-Z0-9+.-]*:/`) or starting with `//`. These are thrown as ERR_INVALID_ARG_VALUE, consistent with the existing path validation pattern. Normal relative paths (e.g. "/foo?q=1", "/bar#hash") are unaffected. The regression test in http-client-path-ssrf-test exercises the patched code path by verifying that http.request() throws ERR_INVALID_ARG_VALUE for absolute URLs, HTTPS URLs, network-path references, and cloud metadata SSRF vectors, while confirming normal paths remain accepted.

This re-buffered the entire entry from offset 0 instead of from the current entryOffset, duplicating already-consumed bytes and inflating queueTotalSize. On the next enqueue, the KJ_REQUIRE at line 1110 (state.queueTotalSize < pending.pullInto.atLeast) would fail because the duplicated bytes made queueTotalSize exceed atLeast. The fix changes bufferData(0) to bufferData(entryOffset) so only the unconsumed tail is buffered. The regression test creates two concurrent readAtLeast(5) BYOB reads with 5-byte views, enqueues 7 bytes (partially consumed by read #1, leaving 2 bytes for read #2's buffer), then enqueues 4 more bytes. Pre-patch this triggers the assertion failure; post-patch both reads complete correctly.

For multi-byte T (e.g. uint32_t), this advances by byteOffset * sizeof(T) bytes instead of byteOffset bytes, producing an out-of-bounds pointer. The non-const overload was already correct: it casts to kj::byte* first, adds byteOffset, then reinterprets to T*. The fix makes the const overload mirror the non-const overload and adds a byteOffset alignment assertion. The regression test creates a Uint8Array view at byteOffset=4 over a 12-byte ArrayBuffer, writes known byte patterns, then calls the const overload of asArrayPtr() and asserts the returned pointer reads the correct uint32_t values. Before the fix, the const overload advanced by 16 bytes (4 * sizeof(uint32_t)) instead of 4 bytes, reading zeroed memory.

There are cases where it is difficult to acquire the channel token for a SubrequestChannel or ActorClassChannel synchronously, but until now we have needed to do so in order to serialize `Fetcher`s and `DurableObjectClass`es. We can't make serialization itself be async, because this would mess up e-order: A call that needs to wait for something while serializing params might end up being delayed until after some subsequent call which didn't wait, and so would be delivered out-of-order. To avoid this, we make it possible for a call to be sent with an IOU for the channel tokens. This uses `ExternalPusher`. The call embeds an external which is a promise capability. Later, the caller invokes the callee's `ExternalPusher` to push the channel token to it, and resolves the IOU promise to the resulting object. The callee can then unwrap the promise to get their token.

This makes it so `getSubrequestChannel()` and similar methods of `IoChannelFactory` make sure that the contents of a `props` cap table are fully resolved before forwarding on to the `IoChannelFactory` implementation. This means that the underlying implementation of `getSubrequestChannelResolved()` et al doens't need to change to start calling `getResolved()` before trying to downcast channel objects to implementation-specific subclasses. This otherwise would have been really annoying to do in the internal codebase. Relatedly, this adds an `ensureAllResolved()` method to `DynamicWorkerSource`, for resolving channels there. --- src/workerd/io/frankenvalue.h | 26 +++++++ src/workerd/io/io-channels.c++ | 133 +++++++++++++++++++++++++++++++++ src/workerd/io/io-channels.h | 61 ++++++++++++--- src/workerd/io/worker.h | 6 ++ src/workerd/server/server.c++ | 29 +++---- 5 files changed, 228 insertions(+), 27 deletions(-) diff --git a/src/workerd/io/frankenvalue.h b/src/workerd/io/frankenvalue.h index 78e9e3fef8c..84c519132ae 100644 --- a/src/workerd/io/frankenvalue.h +++ b/src/workerd/io/frankenvalue.h @@ -104,6 +104,32 @@ class Frankenvalue { } } + // Kind of like `rewriteCaps()`, but the callback returns + // kj::OneOf, kj::Promise>>, i.e. it may optionally + // decide to be async.
