Don't use glob patterns for these (it would exclude passing tests) - - Glob patterns in exclusions only affect DISCOVERED tests (compiled WASM binaries) — compile-error globs for non-existent suites serve as documentation only - - os-test build must complete before WASM runtime build (`make wasm`) — the runtime commands (sh, cat, etc.) are needed for the kernel ---- - -## 2026-03-21 - US-006 -- Classified all 35 remaining os-test failures into 10 GitHub issues (#31-#40) -- Added 35 fail exclusions to posix-exclusions.json with status `fail`, category, reason, and issue link -- Categories: implementation-gap (23 tests across 4 issues), patched-sysroot (12 tests across 6 issues) -- Fixed fail-exclusion check in test runner to consider both exit code AND native output parity (not just exit code) -- Issue grouping: stdout duplication (#31, 8 tests), realloc semantics (#32, 1), VFS directory+nftw (#33, 6), VFS stat (#34, 4), file descriptor ops (#35, 5), glob (#36, 2), locale (#37, 2), long double (#38, 3), wide char (#39, 2), missing libc (#40, 2) -- Final results: 3029 passing, 178 skipped, 35 fail-excluded (all still correctly failing) -- Files changed: `packages/wasmvm/test/posix-conformance.test.ts`, `packages/wasmvm/test/posix-exclusions.json` -- **Learnings for future iterations:** - - Fail-excluded tests must check BOTH exit code AND native output parity — tests that exit 0 but produce wrong stdout are still "failing" - - stdout duplication is a common pattern in os-test WASM execution — likely a kernel/stdout buffering issue where output gets flushed twice - - malloc/realloc zero-size behavior differs between WASI dlmalloc (non-NULL) and glibc (NULL for realloc(ptr,0)) - - long double is 64-bit in WASM (same as double) — no 80-bit extended precision, affects strtold/wcstold/printf %Lf - - `gh issue create` doesn't auto-create labels — use only existing labels (bug, enhancement, etc.) ---- - -## 2026-03-21 - US-007 -- Created `scripts/validate-posix-exclusions.ts` — standalone validation script for posix-exclusions.json -- 6 checks: key-matches-binary, non-empty-reason, fail-has-issue, valid-category, no-ambiguous-glob-overlap, orphan-detection -- Added `minimatch` as root devDependency (was only in wasmvm package) -- Exits non-zero on validation errors;

Without this, pnpm tsx uses stale compiled JS and changes appear not to take effect. - - The WasmVM driver's `_handleWorkerMessage` delivers stdout to BOTH `ctx.onStdout` (process context callback) AND `proc.onStdout` (driver process callback). This is by design for cross-runtime output forwarding, but means the kernel must never set both to the same function. - - The `spawnManaged` → `spawnInternal` layering: `spawnInternal` wires `options.onStdout` to `ctx.onStdout` and sets `driverProcess.onStdout` to a buffer callback. `spawnManaged` should NOT override the buffer callback with the same options callback. - - 8 pre-existing failures in driver.test.ts (exit code 17 from brush-shell `sh -c` wrapper) are NOT caused by this fix — they exist on the base branch. ---- - -## 2026-03-22 - US-013 -- Fixed VFS directory enumeration (#33) — 6 primary tests + 17 bonus tests now pass (23 total removed from exclusions) -- Root cause 1: Test runner created empty InMemoryFileSystem — os-test binaries using opendir/readdir/scandir/nftw found no directory entries -- Root cause 2: wasi-libc's opendir calls path_open with oflags=0 (no O_DIRECTORY), so kernel-worker's fdOpen treated directories as regular files (vfsFile with ino=0), causing fd_readdir to return ENOTDIR -- Fix 1: Test runner now mirrors native build directory structure into VFS per-suite and sets native cwd to suite's native build directory -- Fix 2: kernel-worker fdOpen now stats the path and detects directories regardless of O_DIRECTORY flag, matching POSIX open(dir, O_RDONLY) semantics -- 23 tests removed from posix-exclusions.json: - - 6 primary (US-013): basic/dirent/{fdopendir,readdir,rewinddir,scandir,seekdir}, basic/ftw/nftw - - 3 sys_stat: basic/sys_stat/{fstat,lstat,stat} (not fstatat — still failing) - - 1 fcntl: basic/fcntl/openat - - 2 glob: basic/glob/{glob,globfree} - - 11 paths: paths/{boot,etc,lib,proc,run,sbin,srv,sys,tmp,usr,var} -- Conformance rate: 3037/3207 passing (94.7%) — up from 3014 (94.0%) -- Files changed: `packages/wasmvm/src/kernel-worker.ts`, `packages/wasmvm/test/posix-conformance.test.ts`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - wasi-libc (wasi-sdk) omits O_DIRECTORY in oflags for some path_open calls — the kernel-worker must NOT rely solely on OFLAG_DIRECTORY to detect directory opens - - The wasmvm package has compiled dist/ used by the worker thread — `pnpm --filter @secure-exec/wasmvm build` is needed after editing kernel-worker.ts or wasi-polyfill.ts - - os-test binaries expect to run from the suite's parent directory (e.g., `basic/`) — readdir tests look for sibling subdirectories - - fd_readdir's ENOTDIR can be caused by getIno returning 0/null when the fd was opened as vfsFile (ino=0 sentinel) instead of preopen - - Native tests also need correct cwd — set cwd in spawn() to the suite's native build directory ---- - -## 2026-03-22 - US-014 -- Fixed VFS stat metadata (#34) — basic/sys_stat/fstatat now passes -- Root cause: fstatat test opens ".."

Since stdout had FDFLAG_APPEND=1, F_GETFD returned 1 (== FD_CLOEXEC). Fixed by (a) creating fcntl_override.c that properly tracks per-fd cloexec flags, linked with all os-test WASM binaries via Makefile, and (b) removing incorrect FDFLAG_APPEND from stdout/stderr in fd-table.ts (character devices don't need APPEND). -- Root cause 2 (faccessat): test calls faccessat(dir, "basic/unistd/faccessat.c", F_OK) checking for source files. VFS only had binary entries. Fixed by mirroring os-test source directory into VFS alongside native build entries. -- Root cause 3 (lseek/read): VFS files had zero size (new Uint8Array(0)). lseek(SEEK_END) returned 0, read() returned EOF.

Override with a custom fcntl linked at compile time. - - FDFLAG_APPEND=1 on stdout/stderr character devices is wrong — real Linux terminals don't set O_APPEND, and the value 1 collides with FD_CLOEXEC in wasi-libc's broken implementation. - - os-test binaries expect the SOURCE directory structure in the filesystem (e.g., .c files), not just the build directory. VFS must mirror both native build and source trees. - - VFS files must have non-zero sizes — tests like lseek(SEEK_END) and read() check file content. Use statSync to match native binary sizes. - - The os-test Makefile `exit 1` on compile failures is expected (2095/5302 tests can't compile for WASI) but doesn't prevent binary generation — all compilable tests are built. - - Use `-Wl,--wrap=fcntl` or direct override .c files to fix wasi-libc bugs without a full patched sysroot.

For WASM-specific fixes, can replace test source file in Makefile via srcfile substitution. - - RFC 5952 IPv6 formatting: prefer leftmost zero run when tied, min 2 groups for `::`, single zero fields stay as `0` - - The `after_gap` flag pattern prevents extra `:` separator after `::` in IPv6 formatting ---- - -## 2026-03-22 - US-023 -- Moved 5 libc override fixes from os-test-only (os-test-overrides/) to patched sysroot (patches/wasi-libc-overrides/ and patches/wasi-libc/0009-realloc): - - **fcntl**: Override .c compiled and added to libc.a, replacing original fcntl.o - - **strfmon/strfmon_l**: Override .c compiled and added, replacing original strfmon.o - - **open_wmemstream**: Override .c compiled and added, replacing original open_wmemstream.o - - **swprintf**: Converted from __wrap to direct replacement, compiled and added - - **inet_ntop**: Converted from __wrap to direct replacement, compiled and added - - **realloc**: Used dlmalloc's built-in REALLOC_ZERO_BYTES_FREES flag (patch 0009) — Clang builtin assumptions prevented wrapper-level fix -- Modified `patch-wasi-libc.sh` to: remove original .o from libc.a, compile overrides, add override .o -- Fixed 0008-sockets.patch line count (336→407 for host_socket.c hunk) -- Removed OS_TEST_WASM_OVERRIDES (was 5 override files, now empty) and OS_TEST_WASM_LDFLAGS (--wrap flags) from Makefile -- Deleted 5 override files from os-test-overrides/ (kept namespace_main.c and ffsll_main.c) -- 17 newly-compiled tests added to posix-exclusions.json (poll, select, fmtmsg, stdio/wchar stdin/stdout tests) -- 3350 tests now compile (up from 3207 — sysroot provides more symbols like poll, select, fmtmsg) -- Conformance rate: 3317/3350 passing (99.0%) -- Files changed: `native/wasmvm/patches/wasi-libc-overrides/*.c` (5 new), `native/wasmvm/patches/wasi-libc/0009-realloc-glibc-semantics.patch` (new), `native/wasmvm/patches/wasi-libc/0008-sockets.patch`, `native/wasmvm/scripts/patch-wasi-libc.sh`, `native/wasmvm/c/Makefile`, `native/wasmvm/c/os-test-overrides/` (5 deleted), `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - Clang treats functions named `realloc` as builtins and optimizes based on C standard semantics — a wrapper-level check `if (size == 0) { free(); return NULL; }` gets removed by the compiler even at -O0. Use dlmalloc's `REALLOC_ZERO_BYTES_FREES` flag instead. - - wasi-libc defines dlmalloc functions as `static inline` via `DLMALLOC_EXPORT` — they get inlined into the wrapper functions (malloc, free, realloc) at all optimization levels - - `llvm-objcopy --redefine-sym` does NOT work for WASM object files — only section operations are supported - - `llvm-nm --print-file-name` output format for archives is `path/libc.a:member.o: ADDR TYPE symbol` — parse with `sed 's/.*:\([^:]*\.o\):.*/\1/'` - - `set -euo pipefail` in bash causes `grep` failures in pipelines (no match = exit 1) — wrap in `{ grep ... || true; }` - - Sysroot override compilation must happen AFTER wasm32-wasip1 symlinks are created (clang needs the target-specific include path) - - The sysroot has `libc-printscan-long-double.a` — just needs `-lc-printscan-long-double` linker flag for long double support (US-026) ---- - -## 2026-03-22 - US-024 -- Moved POSIX directory hierarchy from test runner to kernel constructor -- KernelImpl constructor now calls `initPosixDirs()` which creates 30 standard POSIX directories (/tmp, /bin, /usr, /usr/bin, /etc, /var, /var/tmp, /lib, /sbin, /root, /run, /srv, /sys, /proc, /boot, and all /usr/* and /var/* subdirs) plus /usr/bin/env stub file -- `posixDirsReady` promise stored and awaited in `mount()` to ensure dirs exist before any driver uses the VFS -- Removed `populatePosixHierarchy()` function from posix-conformance.test.ts -- Removed `if (suite === 'paths')` suite-specific conditional from test runner -- All 3317 must-pass tests still pass, 32 expected-fail, 1 skip — no regressions -- Conformance rate: 3317/3350 (99.0%) — unchanged -- Files changed: `packages/core/src/kernel/kernel.ts`, `packages/wasmvm/test/posix-conformance.test.ts` -- **Learnings for future iterations:** - - Kernel VFS methods (mkdir, writeFile) are async — constructor can't await them directly. Store the promise and await it in the first async entry point (mount()). - - InMemoryFileSystem.mkdir is declared async but is actually synchronous (just Set.add), so the promise resolves immediately in practice. - - 8 pre-existing driver.test.ts failures (exit code 17 from brush-shell sh -c wrapper) exist on the base branch and are not caused by kernel changes. ---- - -## 2026-03-22 - US-025 -- Reverted ffsll source replacement — upstream test now compiles and runs from original source -- Deleted `native/wasmvm/c/os-test-overrides/ffsll_main.c` -- Removed `OS_TEST_FFSLL_MAIN` variable and `srcfile` substitution case statement from Makefile -- Added `basic/strings/ffsll` to posix-exclusions.json with `expected: fail`, `category: wasm-limitation`, reason explaining sizeof(long)==4 truncation, and issue link to #40 -- Upstream ffsll.c compiles and fails as expected (value truncation on WASM32) -- Conformance rate: 3316/3350 (99.0%) — 33 expected-fail, 1 skip -- Files changed: `native/wasmvm/c/Makefile`, `native/wasmvm/c/os-test-overrides/ffsll_main.c` (deleted), `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - After removing source file overrides from the Makefile, must rebuild os-test WASM binaries (`rm build/os-test/ && make os-test`) — cached binaries still use the old override - - The os-test build `exit 1` on compile failures is expected (1952/5302 tests can't compile for WASI) — it doesn't prevent the 3350 compilable tests from being built ---- - -## 2026-03-22 - US-026 -- Added `-lc-printscan-long-double` to `OS_TEST_WASM_LDFLAGS` in Makefile and included it in the WASM compile command -- All 3 long-double tests now pass with native parity: - - `basic/stdlib/strtold` — parses "42.1end" correctly (42.1 is exactly representable in 64-bit double) - - `basic/wchar/wcstold` — same as strtold but with wide chars - - `stdio/printf-Lf-width-precision-pos-args` — printf %Lf with width/precision/positional args produces '01234.568' -- Removed all 3 from posix-exclusions.json (now 30 expected-fail + 1 skip = 31 exclusions) -- Closed GitHub issue #38 -- Conformance rate: 3319/3350 (99.1%) — up from 3316 (99.0%) -- Files changed: `native/wasmvm/c/Makefile`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json` -- **Learnings for future iterations:** - - `libc-printscan-long-double.a` exists in the wasi-sdk sysroot at `sysroot/lib/wasm32-wasi/` — it just needs `-lc-printscan-long-double` at link time - - On WASM32, `long double` is 64-bit (same as `double`), not 80-bit as on x86-64 — but simple test values like 42.1 and 1234.568 are exactly representable, so tests pass with native parity despite the precision difference - - The previous exclusion reason ("precision differs from native") was wrong — the tests were crashing before reaching any precision comparison because the printf/scanf long-double support library wasn't linked ---- - -## 2026-03-22 - US-027 -- Added /dev/ptmx to device layer — paths/dev-ptmx test now passes -- Added /dev/ptmx to DEVICE_PATHS, DEVICE_INO (0xffff_000b), and DEV_DIR_ENTRIES in device-layer.ts -- Added /dev/ptmx handling in readFile, pread, writeFile (behaves like /dev/tty — reads return empty, writes discarded) -- Removed paths/dev-ptmx from posix-exclusions.json (was expected: fail, category: implementation-gap) -- Conformance rate: 3320/3350 (99.1%) — up from 3319 -- Files changed: `packages/core/src/kernel/device-layer.ts`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - Adding a device to the device layer requires updates in 3 data structures (DEVICE_PATHS, DEVICE_INO, DEV_DIR_ENTRIES) plus read/write/pread method handling - - /dev/ptmx is a PTY master device — in the real kernel it returns a new PTY fd on open, but for os-test paths/ tests it only needs to exist (access check) ---- - -## 2026-03-22 - US-028 -- Recategorized 7 pthread exclusions from `wasm-limitation` to `implementation-gap` with accurate reasons describing the actual wasi-libc stub bugs -- Updated entries: pthread_mutex_trylock, pthread_mutexattr_settype, pthread_mutex_timedlock, pthread_condattr_getclock, pthread_condattr_setclock, pthread_attr_getguardsize, pthread_mutexattr_setrobust -- Long-double tests (strtold, wcstold, printf-Lf) were already removed in US-026 — no changes needed -- Fixed 17 pre-existing entries missing issue URLs (added by US-023 without issue links) — created GitHub issue #45 for stdio/wchar/poll/select/fmtmsg os-test failures -- validate-posix-exclusions.ts now passes clean (was previously broken by missing issue URLs) -- Files changed: `packages/wasmvm/test/posix-exclusions.json` -- **Learnings for future iterations:** - - The validator requires issue URLs for ALL expected-fail entries — always add issue links when creating new exclusions - - Group related implementation-gap entries under a single GitHub issue rather than creating per-test issues - - Honest categorization: `wasm-limitation` = genuinely impossible in wasm32 (no fork, no 80-bit long double); `implementation-gap` = fixable bug in wasi-libc stub or missing build flag ---- - -## 2026-03-22 - US-029 -- Fixed pthread_condattr_getclock/setclock failures — C operator precedence bug in wasi-libc -- Root cause: WASI-specific path in `pthread_condattr_getclock` used `a->__attr & 0x7fffffff == __WASI_CLOCKID_REALTIME`, but `==` has higher precedence than `&`, so it evaluated as `a->__attr & (0x7fffffff == 0)` → always 0 → `*clk` was never set -- Fix: Created patch `0010-pthread-condattr-getclock.patch` that extracts the masked value first (`unsigned id = a->__attr & 0x7fffffff`) then compares with `if/else if` -- Fix goes in wasi-libc source (patch format, not override) because `pthread_condattr_getclock` shares its .o file (`pthread_attr_get.o`) with 12+ other attr getter functions — replacing the .o would break them all -- 2 tests removed from posix-exclusions.json (basic/pthread/pthread_condattr_getclock, basic/pthread/pthread_condattr_setclock) -- Conformance rate: 3322/3350 passing (99.2%) — up from 3320/3350 (99.1%) -- Files changed: `native/wasmvm/patches/wasi-libc/0010-pthread-condattr-getclock.patch`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - C operator precedence: `&` has LOWER precedence than `==` — always parenthesize bitwise operations in comparisons - - Use patches (not overrides) when the target function shares a compilation unit (.o) with other functions — overrides replace the whole .o via `llvm-ar d` + `llvm-ar r`, which would remove all co-located functions - - In WASI, `clockid_t` is a pointer type (`const struct __clockid *`), not an int — `CLOCK_REALTIME` is `(&_CLOCK_REALTIME)`, a pointer to a global. The condattr stores the WASI integer ID internally and must reconstruct the pointer in getclock. - - `__WASI_CLOCKID_REALTIME` = 0 and `__WASI_CLOCKID_MONOTONIC` = 1 — these are the integer IDs stored in `__attr` ---- - -## 2026-03-22 - US-030 -- Fixed pthread mutex trylock, timedlock, and settype via sysroot override -- Root cause: C operator precedence bug in wasi-libc's stub-pthreads/mutex.c — `m->_m_type&3 != PTHREAD_MUTEX_RECURSIVE` parses as `m->_m_type & (3 != 1)` = `m->_m_type & 1`, which inverts NORMAL (type=0) and RECURSIVE (type=1) behavior -- Created `patches/wasi-libc-overrides/pthread_mutex.c` with correct single-threaded mutex semantics -- Uses `_m_count` for lock tracking (not `_m_lock`) for compatibility with stub condvar's `if (!m->_m_count) return EPERM;` check -- Updated `patch-wasi-libc.sh` to remove original `mutex.o` before adding override -- 3 tests removed from posix-exclusions.json (pthread_mutex_trylock, pthread_mutex_timedlock, pthread_mutexattr_settype) -- Conformance rate: 3325/3350 passing (99.3%) — up from 3322/3350 (99.2%) -- Files changed: `native/wasmvm/patches/wasi-libc-overrides/pthread_mutex.c`, `native/wasmvm/scripts/patch-wasi-libc.sh`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json` -- **Learnings for future iterations:** - - wasi-libc uses stub-pthreads (not musl threads) for single-threaded WASM — the stub condvar checks `_m_count` to verify mutex is held, so mutex overrides MUST use `_m_count` for lock tracking - - The stub condvar (`stub-pthreads/condvar.c`) calls `clock_nanosleep` instead of futex — completely different from musl's pthread_cond_timedwait.c - - C operator precedence: `&` has LOWER precedence than `!=` — `m->_m_type&3 != 1` is `m->_m_type & (3 != 1)` = `m->_m_type & 1`, NOT `(m->_m_type & 3) != 1` - - Sysroot overrides that replace mutex.o must also handle `pthread_mutex_consistent` since it's in the same .o file (stub-pthreads combines all mutex functions into one mutex.o) - - Timing-dependent POSIX tests can regress if mutex operations become faster — the stub condvar's `__timedwait_cp` relies on `clock_gettime` elapsed time to trigger ETIMEDOUT before reaching futex code ---- - -## 2026-03-22 - US-031 -- Fixed pthread_attr_getguardsize and pthread_mutexattr_setrobust roundtrip tests -- Root cause: wasi-libc WASI branch rejects non-zero values: - - `pthread_attr_setguardsize`: returns EINVAL for size > 0 (WASI can't enforce guard pages) - - `pthread_mutexattr_setrobust`: returns EINVAL for robust=1 (WASI can't detect owner death) -- Fix: Created `patches/wasi-libc-overrides/pthread_attr.c` with upstream musl behavior: - - `pthread_attr_setguardsize`: stores size in `__u.__s[1]` (same as `_a_guardsize` macro) - - `pthread_mutexattr_setrobust`: stores robust flag in bit 2 of `__attr` (same as upstream) -- Updated `patch-wasi-libc.sh` to remove original `pthread_attr_setguardsize.o` and `pthread_mutexattr_setrobust.o` from libc.a -- 2 entries removed from posix-exclusions.json (23 → 21 exclusions remaining, but still 23 total since previous was 25) -- Conformance rate: 3327/3350 passing (99.3%) — up from 3325/3350 (99.3%) -- Files changed: `native/wasmvm/patches/wasi-libc-overrides/pthread_attr.c` (new), `native/wasmvm/scripts/patch-wasi-libc.sh`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - Each of these functions has its own .o in libc.a (unlike mutex functions which share one .o) — safe to remove individually - - The getters (pthread_attr_getguardsize, pthread_mutexattr_getrobust) are in a shared `pthread_attr_get.o` and already work correctly — only the setters need overriding - - `pthread_attr_t` on WASM32: `__u.__s[]` is `unsigned long[]` (4 bytes each), guardsize at index 1 - - `pthread_mutexattr_t`: single `unsigned __attr` field, bit 2 = robustness, bit 0-1 = type, bit 3 = protocol, bit 7 = pshared ---- - -## 2026-03-22 - US-032 -- Fixed pthread_key_delete hang — test now passes, exclusion removed -- Root cause: `__wasilibc_pthread_self` is zero-initialized (`_Thread_local struct pthread`), so `self->next == NULL`. `pthread_key_delete` walks the thread list via `do td->tsd[k]=0; while ((td=td->next)!=self)` — on second iteration, td=NULL, causing infinite loop/trap in WASM linear memory (address 0 is valid WASM memory) -- Fix: sysroot override `patches/wasi-libc-overrides/pthread_key.c` replaces the entire TSD compilation unit (create, delete, tsd_run_dtors share static `keys[]` array). Override clears `self->tsd[k]` directly instead of walking the thread list — single-threaded WASM has only one thread. -- Override uses musl internal headers (`pthread_impl.h`) for `struct __pthread` access, compiled with extra `-I` flags for `libc-top-half/musl/src/internal` and `arch/wasm32` -- Updated `patch-wasi-libc.sh`: added `__pthread_key_create` to symbol removal list, added musl internal include paths for pthread_key override -- 1 test removed from posix-exclusions.json (basic/pthread/pthread_key_delete) -- Conformance: 3328/3350 (99.3%) — up from 3327 (99.3%) -- Files changed: `native/wasmvm/patches/wasi-libc-overrides/pthread_key.c` (new), `native/wasmvm/scripts/patch-wasi-libc.sh`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - `__wasilibc_pthread_self` is a `_Thread_local struct pthread` that is zero-initialized — `next`, `prev`, `tsd` are all NULL. Any code that walks the thread list (td->next circular loop) will hang/trap. - - The TSD compilation unit (pthread_key_create.c) defines `keys[]`, `__pthread_tsd_main`, and `__pthread_tsd_size` as globals shared between create/delete/dtors — must replace all three together. - - Sysroot overrides that need musl internals (struct __pthread) require `-I` for both `src/internal/` and `arch/wasm32/` directories, plus `#define hidden __attribute__((__visibility__("hidden")))` before including `pthread_impl.h`. - - musl's `weak_alias()` macro is only available inside the musl build — overrides must use `__attribute__((__weak__, __alias__(...)))` directly. - - `__pthread_rwlock_*` (double-underscore) functions are internal — overrides must use the public `pthread_rwlock_*` API. ---- - -## 2026-03-22 - US-033 -- No code changes needed — all acceptance criteria were already met by US-024 -- Verified: no `if (suite === ...)` conditionals exist in posix-conformance.test.ts -- Verified: `populatePosixHierarchy()` function is absent (removed in US-024) -- Verified: `populateVfsForSuite()` applies the same logic for all suites uniformly -- Verified: all 3328/3350 tests pass (22 expected-fail), typecheck clean -- Files changed: `scripts/ralph/prd.json` (marked passes: true), `scripts/ralph/progress.txt` -- **Learnings for future iterations:** - - Check if earlier stories already accomplished the work before implementing — US-024 completed the kernel migration AND removed the test runner special-casing in the same commit - - When a story depends on another story, verify the dependent work wasn't already done as part of the dependency ---- - -## 2026-03-22 - US-034 -- Confirmed /dev/ptc and /dev/ptm are Sortix-specific paths that don't exist on real Linux -- Native tests exit 1 with "/dev/ptc: ENOENT" and "/dev/ptm: ENOENT" — identical to WASM output -- Added native parity detection to test runner: when both WASM and native fail with the same exit code and stdout, the test counts as passing (native parity) -- Updated both the non-excluded test path AND the fail-exclusion path to detect identical-failure parity -- Removed both paths/dev-ptc and paths/dev-ptm from posix-exclusions.json (20 exclusions remaining) -- paths suite now at 100.0% (48/48) -- Conformance rate: 3330/3350 (99.4%) — up from 3328/3350 (99.3%) -- Files changed: `packages/wasmvm/test/posix-conformance.test.ts`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - os-test paths/ tests use `access(path, F_OK)` + `err(1, ...)` — if the path doesn't exist, both WASM and native produce identical ENOENT output on stderr and empty stdout - - /dev/ptc and /dev/ptm are Sortix-specific (the os-test project is from Sortix OS) — they don't exist on Linux - - Native parity for failure cases: when both WASM and native exit with the same code and output, the test has perfect parity even though it "fails" — this is correct behavior for platform-specific tests - - The fail-exclusion path also needs native parity detection — otherwise a fail-excluded test that matches native behavior won't be detected as "unexpectedly passing" ---- - -## 2026-03-22 - US-035 -- Updated 17 exclusion reasons in posix-exclusions.json to reflect actual root causes: - - 7 stdio/wchar stdout tests (printf, puts, putchar, vprintf, putwchar, vwprintf, wprintf): test closes fd 1, creates pipe via pipe()+dup2() to redirect stdout — kernel pipe/dup2 integration with WASI stdio FDs not yet supported - - 6 stdio/wchar stdin tests (getchar, scanf, vscanf, getwchar, wscanf, vwscanf): test closes fd 0, creates pipe via pipe()+dup2() to redirect stdin — same root cause - - poll: only supports socket FDs via host_net bridge — pipe FDs not pollable (netPoll returns POLLNVAL) - - select, sys_time/select: same root cause as poll — pipe FDs not selectable - - fmtmsg: not implemented in wasi-libc + also relies on pipe()+dup2() to capture stderr -- No code changes besides posix-exclusions.json — purely a documentation/accuracy fix -- Validator passes clean, all 3350 tests pass (3330 must-pass + 20 expected-fail) -- Files changed: `packages/wasmvm/test/posix-exclusions.json` -- **Learnings for future iterations:** - - All os-test stdio/wchar tests use the same pattern: close(0/1) → pipe() (gets fds 0+1) → dup2() to redirect — the root cause is uniform across all 13 tests - - The kernel's netPoll in kernel-worker.ts only checks this._sockets map — pipe FDs are kernel-routed and not in the socket map, so they return POLLNVAL - - fmtmsg has TWO issues: the function itself isn't implemented in wasi-libc AND the test uses pipe+dup2 — both need fixing ---- - -## 2026-03-22 - US-036 -- Fixed FDTable to recycle FDs 0/1/2 — enables POSIX lowest-available FD semantics for pipe() -- Root cause: `FDTable.close()` in fd-table.ts had `if (fd >= 3)` check that prevented FDs 0/1/2 from being added to `_freeFds`. os-test stdio/wchar tests do `close(0); close(1); pipe(fds)` expecting pipe() to return fds 0,1 (POSIX lowest-available). Without recycling, pipe() got fds 3+ and the stdio redirection failed. -- Fix: removed `fd >= 3` restriction, added descending sort on `_freeFds` so `pop()` returns the lowest available fd (POSIX semantics) -- 13 stdio/wchar tests now pass: printf, puts, putchar, vprintf, getchar, scanf, vscanf, putwchar, vwprintf, wprintf, getwchar, wscanf, vwscanf -- fmtmsg changed from `expected: fail` to `expected: skip` (timeout) — musl's fmtmsg() is a no-op (returns MM_OK without writing to stderr), so the test hangs on fread(stdin) waiting for pipe data that never arrives -- 13 entries removed from posix-exclusions.json (20 → 7 exclusions) -- Conformance rate: 3343/3350 (99.8%) — up from 3330/3350 (99.4%) -- Files changed: `packages/wasmvm/src/fd-table.ts`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - POSIX requires pipe()/open()/dup() to return the lowest available FD — the FDTable must recycle ALL closed FDs including 0/1/2 - - `_freeFds` must be sorted (descending for pop-gives-lowest) to guarantee POSIX ordering — LIFO stack gives wrong order (close(0), close(1), pipe → pop gives 1 first, not 0) - - proc.closeStdin() in the test runner is harmless — it closes the kernel stdin pipe, but the binary's own close(0) still reclaims local fd 0 for reuse - - musl's fmtmsg() at `src/legacy/fmtmsg.c` returns 0 (MM_OK) without writing anything — the fmtmsg test expects output on stderr, hangs on pipe read waiting for EOF that never arrives due to pipe write end refcount issue in dup2 chain ---- - -## 2026-03-22 - US-037 -- Extended poll/select to support pipe FDs — all 3 tests now pass -- Changes across 5 files: - 1. **pipe-manager.ts**: Added `pollState(descId)` — queries buffer/closed state to determine readable/writable/hangup for each pipe end - 2. **kernel.ts**: Added `fdPoll(pid, fd)` — routes to pipeManager for pipe FDs, returns always-ready for regular files - 3. **types.ts**: Added `fdPoll` to `KernelInterface` - 4. **kernel-worker.ts**: `net_poll` now translates local FDs → kernel FDs via `localToKernelFd` before sending to driver; removed `isNetworkBlocked()` gate (poll is a generic FD op, not network-specific) - 5. **driver.ts**: `netPoll` handler now checks `kernel.fdPoll(pid, fd)` for non-socket FDs instead of returning POLLNVAL -- Also fixed sysroot conflict: musl's `select.o` and `poll.o` in libc.a conflicted with our `host_socket.o` implementations — added `select.o poll.o` to the `ar d` removal in `patch-wasi-libc.sh` -- 3 entries removed from posix-exclusions.json (7 → 4 exclusions) -- Conformance rate: 3346/3350 (99.9%) — up from 3343/3350 (99.8%) -- Files changed: `packages/core/src/kernel/pipe-manager.ts`, `packages/core/src/kernel/kernel.ts`, `packages/core/src/kernel/types.ts`, `packages/wasmvm/src/kernel-worker.ts`, `packages/wasmvm/src/driver.ts`, `native/wasmvm/scripts/patch-wasi-libc.sh`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - musl's select() uses `__wasi_poll_oneoff` (which always reports "ready") — our custom select() in host_socket.c calls poll() → net_poll (which checks actual FD state). Must remove musl's select.o from libc.a to avoid symbol conflict. - - `net_poll` in kernel-worker must translate local→kernel FDs before sending to driver — the driver's socket map uses kernel FDs (socket IDs), not local FDs - - The `isNetworkBlocked()` gate on `net_poll` prevented pipe-only poll calls — poll() is a generic POSIX operation and shouldn't require network permission - - PipeManager.pollState() for read end: readable = buffer.length > 0 || write end closed; for write end: writable = read end open && buffer < 64KB - - Rebuilding sysroot requires `make sysroot` in `native/wasmvm/c/`, then `rm build/os-test/` + `make os-test` to recompile ---- - -## 2026-03-22 - US-038 -- Implemented fmtmsg() sysroot override — musl's was a no-op stub returning 0 without writing -- Created `patches/wasi-libc-overrides/fmtmsg.c`: POSIX-conformant implementation writing "label: severity: text\nTO FIX: action tag\n" to stderr -- Added `fmtmsg` to symbol removal list in `patch-wasi-libc.sh` -- Also fixed critical dup2 bug in kernel-worker.ts: `localToKernelFd.set(new_fd, kOldFd)` → `localToKernelFd.set(new_fd, kNewFd)`. Old code caused pipe write end to leak when using dup2 redirect+restore pattern (fmtmsg test: dup2 stderr→pipe, then dup2 restore→real stderr — the pipe write fd at kernel level was orphaned) -- fmtmsg removed from posix-exclusions.json (4 → 3 exclusions) -- Conformance rate: 3347/3350 (99.9%) — up from 3346/3350 (99.9%) -- Files changed: `native/wasmvm/patches/wasi-libc-overrides/fmtmsg.c` (new), `native/wasmvm/scripts/patch-wasi-libc.sh`, `packages/wasmvm/src/kernel-worker.ts`, `packages/wasmvm/test/posix-exclusions.json`, `posix-conformance-report.json`, `docs/posix-conformance-report.mdx` -- **Learnings for future iterations:** - - dup2 kernel FD mapping must use kNewFd (the target kernel fd) not kOldFd (the source): after kernel dup2(old, new), new_fd "owns" kernel fd kNewFd. Using kOldFd causes shared kernel fd issues where closing one local fd accidentally affects another. - - The dup2 redirect+restore pattern (dup stderr, redirect to pipe, restore) triggers the bug because it creates two kernel refs to the pipe write, then dup2 restore replaces only the mapped one, leaving the identity-mapped one as a leaked reference. - - musl's fmtmsg stub is at src/legacy/fmtmsg.c and returns 0 without writing — override must be added to both the symbol removal list and the overrides directory. ---- - -## 2026-03-22 - US-039 -- Fixed /dev/full to return ENOSPC on write instead of silently discarding -- Added ENOSPC to KernelErrorCode type in types.ts -- Added ERRNO_ENOSPC (51) to wasi-constants.ts and ERRNO_MAP -- device-layer.ts writeFile now throws KernelError("ENOSPC") for /dev/full -- No regressions — paths/dev-full only checks access(F_OK), not write behavior -- Files changed: `packages/core/src/kernel/device-layer.ts`, `packages/core/src/kernel/types.ts`, `packages/wasmvm/src/wasi-constants.ts` -- **Learnings for future iterations:** - - WASI errno for ENOSPC is 51 (from WASI spec `__wasi_errno_t`) - - Adding a new error code requires 3 changes: KernelErrorCode type, ERRNO constant, ERRNO_MAP entry ---- - -## 2026-03-22 - US-040 -- Created `scripts/posix-exclusion-schema.ts` as single source of truth for exclusion types -- Exports: VALID_CATEGORIES, VALID_EXPECTED, ExclusionCategory, ExclusionExpected, ExclusionEntry, ExclusionsFile, CATEGORY_META, CATEGORY_ORDER -- Updated 3 consumers to import from shared module: - - validate-posix-exclusions.ts: removed inline VALID_EXPECTED, VALID_CATEGORIES, ExclusionEntry - - generate-posix-report.ts: removed inline ExclusionEntry, ExclusionsFile, CATEGORY_META, categoryOrder - - posix-conformance.test.ts: removed inline ExclusionEntry interface -- generate-posix-report.ts now throws on unknown categories (was silently skipping) -- Files changed: `scripts/posix-exclusion-schema.ts` (new), `scripts/validate-posix-exclusions.ts`, `scripts/generate-posix-report.ts`, `packages/wasmvm/test/posix-conformance.test.ts` ---- - -## 2026-03-22 - US-041 -- Hardened import-os-test.ts with safe extraction and validation -- Extract to temp dir (`os-test-incoming/`) first, validate .c files exist, then atomic swap via `renameSync` -- Old os-test/ only deleted after new source is validated — prevents broken state on download/extract failure -- Added `resolveCommitHash()` using `git ls-remote` to resolve branch names to actual commit hashes -- Script now auto-updates osTestVersion, sourceCommit, and lastUpdated in posix-exclusions.json -- Added version format validation (alphanumeric, dash, dot, slash) before download attempt -- Removed step 4 from "Next steps" (metadata update) since it's now automatic -- Files changed: `scripts/import-os-test.ts` -- **Learnings for future iterations:** - - `renameSync` is atomic on the same filesystem — use temp dir + rename for safe file replacement instead of delete-then-extract - - `git ls-remote` works for GitLab repos too (standard git protocol) — returns hash + ref tab-separated - - os-test suite dirs are at top level (basic/, io/, etc.) not under src/ — validation checks for .c files anywhere in the tree ---- - -## 2026-03-22 - US-042 -- Fixed three CI/tooling gaps: - 1. **CI workflow path triggers**: Added `scripts/generate-posix-report.ts`, `scripts/import-os-test.ts`, and `scripts/posix-exclusion-schema.ts` to both push and pull_request path triggers in `.github/workflows/posix-conformance.yml` - 2. **Issue URL validation**: `validate-posix-exclusions.ts` now checks issue URLs match `https://github.com/rivet-dev/secure-exec/issues/` pattern via regex — catches typos like `htps://` or wrong org/repo - 3. **Native parity label**: `generate-posix-report.ts` now shows "X of Y passing tests verified against native (Z%)" instead of just "Z%" — clarifies the denominator -- Files changed: `.github/workflows/posix-conformance.yml`, `scripts/validate-posix-exclusions.ts`, `scripts/generate-posix-report.ts` -- **Learnings for future iterations:** - - CI path triggers should include ALL scripts that are run by the workflow, not just the test runner — missing triggers means script changes don't get validated in CI - - The shared schema module (`posix-exclusion-schema.ts`) should also be in path triggers since all three scripts depend on it ---- - -## 2026-03-23 - US-043 -- Implemented F_DUPFD and F_DUPFD_CLOEXEC in fcntl sysroot override -- Full call path: fcntl.c → __host_fd_dup_min (host_process import) → kernel-worker fd_dup_min → RPC fdDupMin → kernel dupMinFd -- Changes: - 1. **fcntl.c** (sysroot override): Added F_DUPFD and F_DUPFD_CLOEXEC cases calling __host_fd_dup_min host import. Defined F_DUPFD=0 and F_DUPFD_CLOEXEC=1030 since WASI headers omit these. - 2. **fd-table.ts**: Added dupMinFd(fd, minFd) method to local FDTable for lowest-available-FD-above-minFd allocation - 3. **kernel-worker.ts**: Added fd_dup_min host_process import handler that translates local→kernel FDs and routes through RPC - 4. **driver.ts**: Added 'fdDupMin' RPC dispatch case - 5. **kernel.ts**: Added fdDupMin implementation delegating to ProcessFDTable.dupMinFd - 6. **types.ts**: Added fdDupMin to KernelInterface - 7. **browser-driver.test.ts**: Added fdDupMin mock -- Files changed: native/wasmvm/patches/wasi-libc-overrides/fcntl.c, packages/wasmvm/src/fd-table.ts, packages/wasmvm/src/kernel-worker.ts, packages/wasmvm/src/driver.ts, packages/core/src/kernel/kernel.ts, packages/core/src/kernel/types.ts, packages/wasmvm/test/browser-driver.test.ts -- **Learnings for future iterations:** - - WASI sysroot headers omit F_DUPFD and F_DUPFD_CLOEXEC defines — must add them manually in any C override that references them - - Adding new host_process imports requires changes at 5 layers: C import decl, kernel-worker handler, RPC dispatch in driver.ts, kernel implementation, and KernelInterface type - - Local FDTable and kernel FDTable are separate — F_DUPFD minFd constraint applies to LOCAL fd space (what WASM sees), kernel fd can be any number since localToKernelFd maps them - - After editing kernel source (types.ts, kernel.ts), must run `pnpm --filter @secure-exec/core build` before wasmvm typecheck will pass ---- - -## 2026-03-23 - US-044 -- Added EINVAL bounds check to pthread_key_delete in patches/wasi-libc-overrides/pthread_key.c -- Returns EINVAL for k >= PTHREAD_KEYS_MAX (out-of-range) and for keys[k] == 0 (unallocated/double-delete) -- Bounds check placed before lock acquisition for efficiency -- Files changed: `native/wasmvm/patches/wasi-libc-overrides/pthread_key.c` -- **Learnings for future iterations:** - - POSIX pthread_key_delete requires EINVAL for invalid keys — musl's upstream implementation also validates, but the single-threaded override had skipped validation - - The keys[] array uses non-NULL function pointers as "allocated" markers (nodtor sentinel for NULL dtors), so keys[k] == 0 reliably detects unallocated slots - - pthread_key_t is an unsigned type so only upper bound check needed (no negative check) ---- - -## 2026-03-23 - US-045 -- Replaced fixed 1024-byte buffer in fmtmsg.c with dynamic allocation proportional to input sizes -- Added MM_RECOVER/MM_NRECOV classification validation (returns MM_NOTOK if both are set simultaneously) -- Updated doc comment to document handling of all POSIX classification flags -- Rebuilt patched sysroot and os-test WASM binaries -- All 3350 POSIX conformance tests pass, 0 regressions -- Files changed: `native/wasmvm/patches/wasi-libc-overrides/fmtmsg.c` -- **Learnings for future iterations:** - - POSIX classification flags (MM_HARD/SOFT/FIRM, MM_APPL/UTIL/OPSYS, MM_RECOVER/MM_NRECOV) do NOT affect the output text format — they're metadata for message routing. The output format is always "label: severity: text\nTO FIX: action tag\n" - - MM_RECOVER and MM_NRECOV are mutually exclusive per POSIX — setting both is an error - - Dynamic allocation in fmtmsg is safe since all string inputs have bounded length from the caller ---- - -## 2026-03-23 - US-046 -- Changed `pollState()` read-end readable check from `state.buffer.length > 0` (chunk count) to `this.bufferSize(state) > 0` (byte count) -- This matches the write-end writable check which already used `bufferSize()` -- Prevents theoretical false-negative on POLLIN if an empty chunk were in the buffer -- All 3350 POSIX conformance tests pass including poll/poll, sys_select/select, sys_time/select -- No regressions -- Files changed: `packages/core/src/kernel/pipe-manager.ts` -- **Learnings for future iterations:** - - Poll/select os-test binaries take ~23s in WASM (close to the 30s timeout) — they may timeout if run individually with `-t` filter since the kernel isn't warmed up; the full suite run succeeds because kernel is already initialized - - PipeManager.bufferSize() iterates all chunks to sum byte lengths — consistent usage across pollState prevents inconsistency between read-end and write-end checks ---- - -## 2026-03-23 - US-047 -- Added /opt, /mnt, /media, /home to initPosixDirs() in kernel.ts -- Added /dev/shm to DEVICE_DIRS in device-layer.ts (alongside existing /dev/fd and /dev/pts) -- Added pts and shm entries to DEV_DIR_ENTRIES so they appear in readdir("/dev") -- All 48 paths/* conformance tests pass with no regressions -- Files changed: `packages/core/src/kernel/kernel.ts`, `packages/core/src/kernel/device-layer.ts` -- **Learnings for future iterations:** - - /dev subdirectories (pts, shm) must be added to DEVICE_DIRS in device-layer.ts, not initPosixDirs() — the device layer intercepts /dev/* paths before VFS - - DEV_DIR_ENTRIES must be kept in sync with DEVICE_DIRS — missing entries mean readdir("/dev") won't list the directory even though stat() works - - os-test paths/ suite doesn't have tests for /opt, /mnt, /media, /home, /dev/shm — these directories are FHS 3.0 standard but not tested by the current os-test version +- Native V8 `StreamEvent` payloads are not always V8-serialized; `native/v8-runtime/src/stream.rs` must fall back to UTF-8 JSON/string decoding or timer/stream dispatch callbacks can stall silently +- Keep `MODULE_RESOLVE_STATE` alive until async ESM execution fully finalizes; native top-level await plus dynamic `import()` still needs the bridge context and module cache after `execute_module()` first returns +- `packages/v8/src/runtime.ts` prefers `native/v8-runtime/target/release/secure-exec-v8` over debug builds, so rebuild the release binary before validating native V8 runtime changes through package tests +- After editing `packages/core/isolate-runtime/src/inject/*`, regenerate `packages/core/src/generated/isolate-runtime.ts` via `node packages/nodejs/scripts/build-isolate-runtime.mjs` before running Node runtime tests +- Bridge handler callbacks that need optional dispatch arguments should accept them explicitly; do not inspect extra bridge-call args through `arguments` inside arrow functions +- In `ProcessTable` signal delivery, apply one-shot disposition resets before `deliverPendingSignals()` so a same-signal delivery queued during the handler observes `SIG_DFL` instead of reusing the old callback +- Keep procfs state canonical in `packages/core/src/kernel/proc-layer.ts` as `/proc/` entries, and resolve `/proc/self` only in per-process runtime/VFS adapters where the current PID is known +- Cross-package tests that import workspace packages like `@secure-exec/core` execute the built `dist` output; rebuild the changed package with `pnpm turbo run build --filter=` before Vitest runs or you'll exercise stale JS +- `FileLockManager.flock()` is async; keep blocking advisory locks bounded with a timed `WaitQueue` retry loop and wake the next waiter from every last-reference unlock path +- For bounded blocking producers like `PipeManager.write()`, commit any bytes that fit before enqueueing a `WaitQueue`, and wake blocked writers from both drain paths and close paths so waits cannot hang +- `KernelInterface.fdOpen()` is synchronous, so open-time file semantics must go through sync-capable VFS hooks threaded through device/permission wrappers instead of async read/write fallbacks +- When `InMemoryFileSystem` exposes POSIX-only `.` / `..` directory entries, keep Node semantics by filtering them in `packages/nodejs/src/bridge-handlers.ts` before they reach `fs.readdir()` +- Kernel-owned `InMemoryFileSystem` instances must be rebound to `kernel.inodeTable` via `setInodeTable(...)` before device/permission wrapping; deferred-unlink FD I/O should use raw inode helpers (`readFileByInode`, `writeFileByInode`, `statByInode`) instead of pathname lookups +- `PtyManager` raw-mode bulk input still applies `icrnl`; translate the whole chunk before `deliverInput()` so oversized writes fail atomically with `EAGAIN` instead of partially buffering data +- Deferred unlink in `InMemoryFileSystem` must keep only live path → inode entries; open FDs survive unlink via `FileDescription.inode` and inode-backed reads, not by leaving removed pathnames accessible +- Any open-FD file I/O path in `KernelImpl` must stay description-based (`readDescriptionFile` / `writeDescriptionFile` / `preadDescription`) rather than path-based VFS calls, or deferred-unlink behavior regresses for `pread`/`pwrite`-style operations +- `SocketTable.connect()` must accept sockets already in `bound` state so WasmVM/libc callers can bind first, then use `getsockname()`/`getpeername()` with stable local addresses +- When `SocketTable.bind()` assigns a kernel ephemeral port for `port: 0`, keep a `requestedEphemeralPort` marker on the socket so external `listen(..., { external: true })` can still delegate `port: 0` to the host adapter before rewriting `localAddr` to the real host-assigned port +- Signal-aware blocking socket waits should use `ProcessSignalState.signalWaiters` plus `deliverySeq/lastDeliveredFlags`; wire `SocketTable` with `getSignalState` from the shared `ProcessTable` instead of open-coding runtime-specific signal polling +- Non-blocking external socket connect should reject with `EINPROGRESS` immediately but leave the kernel socket in a transient `connecting` state and finish `hostAdapter.tcpConnect()` in the background +- WasmVM `host_net` socket/domain constants coming from wasi-libc bottom-half do not match `packages/core` socket constants; normalize them at the WasmVM driver boundary before calling `kernel.socketTable` +- WasmVM `host_net` socket option payloads cross the worker RPC boundary as little-endian byte buffers; decode/encode them in `packages/wasmvm/src/driver.ts` and keep `packages/wasmvm/src/kernel-worker.ts` as a thin memory marshal layer +- In `packages/wasmvm/src/kernel-worker.ts`, socket FDs must be allocated in the worker-local `FDTable` and mapped through `localToKernelFd` — returning raw kernel socket IDs collides with stdio FDs and breaks close/flush behavior +- Cooperative WasmVM signal delivery during `poll_oneoff` sleep needs a periodic hook back through RPC; pure `Atomics.wait()` sleeps do not observe pending kernel signals +- When adding bridge globals that are called directly from the bridge IIFE, update all three inventories together: `packages/*/src/bridge-contract.ts`, `packages/core/src/shared/global-exposure.ts`, and `native/v8-runtime/src/session.rs` (`SYNC_BRIDGE_FNS` / `ASYNC_BRIDGE_FNS`) +- In `native/v8-runtime`, sync bridge calls must only consume `BridgeResponse` frames for their own `call_id`; defer mismatched responses back to the session event loop or sync calls will steal async promise results +- Host-side loopback access for sandbox HTTP servers is gated through `createDefaultNetworkAdapter().__setLoopbackPortChecker(...)`; keep the checker aligned with the active kernel-backed HTTP server set rather than reviving driver-level owned-port maps +- Standalone `NodeExecutionDriver` already provisions an internal `SocketTable` with `createNodeHostNetworkAdapter()`; do not reintroduce `NetworkAdapter.httpServerListen/httpServerClose` for loopback server tests — use sandbox `http.createServer()` plus `initialExemptPorts` or the loopback checker hook when a host-side request must reach the sandbox listener +- Node's default network adapter exposes an internal `__setLoopbackPortChecker` hook; NodeExecutionDriver must wire it before `wrapNetworkAdapter()` so host-side fetch/httpRequest can reach kernel-owned loopback listeners without reviving `ownedServerPorts` +- For new Node bridge operations that need kernel-backed host state but not a new native bridge function, route them through `_loadPolyfill` `__bd:` dispatch handlers; reserve new runtime globals for host-to-isolate event dispatch like `_timerDispatch` +- Kernel implementation lives in packages/core/src/kernel/ — KernelImpl is the main class +- UDP and TCP use separate binding maps in SocketTable (listeners for TCP, udpBindings for UDP) — same port can be used by both protocols +- Kernel tests go in packages/core/test/kernel/ +- WasmVM WASI extensions are declared in native/wasmvm/crates/wasi-ext/src/lib.rs +- C sysroot patches for WasmVM are in native/wasmvm/patches/wasi-libc/

Bridge handlers not in the Rust V8 SYNC_BRIDGE_FNS array are dispatched through _loadPolyfill via BRIDGE_DISPATCH_SHIM in execution-driver.ts +- To add new bridge globals: (1) add key to HOST_BRIDGE_GLOBAL_KEYS in bridge-contract.ts, (2) add handler to dispatch handlers in execution-driver.ts, (3) use _globalName.applySyncPromise(undefined, args) in bridge code +- FD table is managed on the host side via kernel ProcessFDTable (FDTableManager from @secure-exec/core) — bridge/fs.ts delegates FD ops through bridge dispatch +- After modifying bridge/fs.ts, run `pnpm turbo run build --filter=@secure-exec/nodejs` to rebuild the bridge IIFE before running tests +- Node conformance tests are in packages/secure-exec/tests/node-conformance/ +- PATCHED_PROGRAMS in

private `listeners` Map (addr key → socket ID) for port reservation and routing; addrKey() is exported for address key formatting +- findListener() checks exact match first, then wildcard 0.0.0.0 and :: — used by connect() for loopback routing +- findBoundUdp() is public on SocketTable — same lookup pattern as findListener but for UDP bindings; used by tests to poll for UDP server readiness +- EADDRINUSE was added to KernelErrorCode in types.ts for socket address conflicts +- connect() creates a server-side socket paired via peerId and queues it in listener's backlog; send/recv use peerId to route data +- destroySocket() clears peerId on peer and wakes its readWaiters for EOF propagation +- consumeFromBuffer() handles partial chunk reads for recv() with maxBytes limit +- ECONNREFUSED and ENOTCONN were added to KernelErrorCode in types.ts +- Half-close uses peerWriteClosed flag on KernelSocket — shutdown('write') sets it on the peer, recv() checks it for EOF detection +- State composition: shutdown methods check current state (read-closed/write-closed) and transition to closed when both halves are shut +- Socket options use optKey(level, optname) → "level:optname" composite keys in the options Map; use setsockopt/getsockopt methods, not direct Map access +- Socket flags (MSG_PEEK, MSG_DONTWAIT, MSG_NOSIGNAL) are bitmask values matching Linux constants; use bitwise AND to check +- SocketTable accepts optional `networkCheck` in constructor for permission enforcement; loopback connect always bypasses checks +- KernelSocket has `external?: boolean` flag for tracking host-adapter-connected sockets (used by send() permission check) +- SocketTable accepts optional `hostAdapter` (HostNetworkAdapter) in constructor for external connection routing +- connect() is async (returns Promise) — all existing tests must use await; loopback path is synchronous inside the async function +- External sockets have `hostSocket?: HostSocket` on KernelSocket — send() writes to hostSocket, a background read pump feeds readBuffer +- destroySocket() calls hostSocket.close() for external sockets +- Mock host adapter pattern: MockHostSocket with pushData()/pushEof() for controlling read pump in tests +- MockHostListener with pushConnection() for simulating incoming external TCP connections in tests +- bind() is async (Promise) like connect() and listen() — all callers must await; sync throw tests use .rejects.toThrow() +- SocketTable accepts optional `vfs` (VirtualFileSystem) in constructor for Unix domain socket file management +- InMemoryFileSystem.chmod() accepts explicit type bits (e.g. S_IFSOCK | 0o755) — if mode & 0o170000 is non-zero, type bits are used directly +- listen() is async (Promise) — all callers must use await; expect(...).toThrow must become await expect(...).rejects.toThrow +- resource-exhaustion.test.ts and kernel-integration.test.ts stdin streaming tests have pre-existing flaky failures — not related to socket work +- Net socket bridge handlers support kernel routing via optional socketTable + pid deps; fallback to direct net.Socket when not provided +- KernelOptions accepts optional hostNetworkAdapter — wired to SocketTable for external connection routing +- KernelInterface exposes socketTable — available to runtime drivers via init(kernel) callback +- SocketTable.close() requires BOTH socketId AND pid for per-process ownership check +- NodeExecutionDriverOptions accepts optional socketTable + pid for kernel socket routing +- NetworkAdapter interface no longer has netSocket* methods — bridge handlers handle all TCP socket operations +- buildNetworkBridgeHandlers returns { handlers, dispose } (NetworkBridgeResult) — kernel HTTP servers need async cleanup +- http.Server + emit('connection', duplexStream) pattern feeds kernel socket data through Node HTTP parser without real TCP +- KernelSocketDuplex wraps kernel sockets as stream.Duplex — needs socket-like props (remoteAddress, setNoDelay, etc.) for http module +- SSRF loopback exemption uses socketTable.findListener() — kernel-aware, no manual port tracking needed +- assertNotPrivateHost/isPrivateIp/isLoopbackHost are in bridge-handlers.ts for kernel-aware SSRF validation +- processTable exposed on KernelInterface — wired through execution-driver to bridge handlers +- wrapAsDriverProcess() adapts SpawnedProcess to kernel DriverProcess (adds null callback stubs) +- childProcessInstances Map in bridge/child-process.ts is event routing only — kernel tracks process state +- WasmVM socket ops route through kernel.socketTable (create/connect/send/recv/close) — hostAdapter handles real TCP +- WasmVM TLS-upgraded sockets bypass kernel recv via _tlsSockets Map — TLS upgrade detaches kernel read pump +- WaitHandle timeout goes in WaitQueue.enqueue(timeoutMs), not WaitHandle.wait() — wait() takes no args +- Test mock kernel: createMockKernel() with SocketTable + TestHostSocket using real node:net — in packages/wasmvm/test/net-socket.test.ts +- Cooperative signal delivery: driver piggybacking via SIG_IDX_PENDING_SIGNAL in SAB, worker calls __wasi_signal_trampoline +- proc_sigaction RPC: action 0=SIG_DFL, 1=SIG_IGN, 2=user handler (C side holds function pointer) +- C sysroot signal handling: signal() + __wasi_signal_trampoline in 0011-sigaction.patch +- Kernel public API: Kernel interface has no kill(pid,signal) — use ManagedProcess.kill() from spawn(), or kernel.processTable internally + +## 2026-03-24 22:12 PDT - US-050 +- What was implemented +- Added synchronous open-time flag handling in `KernelImpl.fdOpen()` for `O_CREAT`, `O_EXCL`, and `O_TRUNC`, with wrapper passthroughs in the device and permission layers +- Added `prepareOpenSync()` support to the in-memory and Node-backed VFS adapters so `fdOpen()` can create empty files, reject `O_CREAT|O_EXCL` on existing paths, and truncate existing files before the descriptor is allocated +- Added kernel integration coverage for `O_CREAT|O_EXCL`, `O_TRUNC`, `O_TRUNC|O_CREAT`, and the `O_EXCL`-without-`O_CREAT` no-op case; updated the kernel contract and root

detection in recv: peerId === undefined means peer closed; readBuffer empty + peerId undefined → return null + - connect() creates the server-side socket with listener.pid as owner — the process that

local send() still works +- shutdown('both'): combines both, transitions to 'closed' +- Sequential half-close: read-closed + shutdown('write') → closed, write-closed + shutdown('read') → closed +- Updated send() to check write-closed/closed states before ENOTCONN +- Updated recv() to return null immediately for read-closed/closed states and check peerWriteClosed for EOF +- Updated poll() to

packages/core/src/kernel/socket-table.ts (socketpair method), packages/core/test/kernel/socketpair.test.ts (new, 13 tests) +- **Learnings for future iterations:** + - socketpair() is much simpler than connect() — no listener lookup, just create two sockets and cross-link peerId + - All existing send/recv/close/shutdown logic works unchanged for socketpair — the peerId linking is the only mechanism needed + - EMFILE limit applies to socketpair too — creating 2 sockets at once can exceed the limit after the first succeeds +--- + +## 2026-03-23 - US-009 +- Implemented setsockopt() and getsockopt()

MSG_* flag values: MSG_PEEK=0x2, MSG_DONTWAIT=0x40, MSG_NOSIGNAL=0x4000 — match Linux constants for compatibility +--- +## 2026-03-24 22:20 PDT - US-051 +- Implemented blocking advisory `flock()` with

waiter wakeups must happen on all last-reference release paths (`LOCK_UN`, `fdClose`, `dup2` replacement, process-exit cleanup) because the kernel funnels them through `releaseByDescription()` + - `KernelInterface.flock()` now returns a `Promise`; direct tests and future bridge callers must `await` it even when the lock is uncontended +--- + +## 2026-03-23 - US-011 +- Implemented network permission checks in SocketTable: checkNetworkPermission() public method, wired into connect(), listen(), and send() +--- + +- connect() to loopback (kernel listener) always bypasses permission

checkNetworkPermission, connect/listen/send permission checks, external flag), packages/core/test/kernel/network-permissions.test.ts (new, 17 tests) +- **Learnings for future iterations:** + - SocketTable accepts `networkCheck` in constructor options — when set, listen() and external connect() are permission-checked + - Loopback connect (findListener returns a match) always bypasses permission — this is by design per spec + - When no networkCheck is configured, existing behavior is preserved (no enforcement) — backwards compatible + - Tests that need loopback with restricted policy must allow "listen" op but deny "connect" — denyAll breaks listener setup + - The `external` flag on KernelSocket will be set by US-012 (host adapter routing) — for now it's only used in tests

sendTo = one datagramQueue entry; recvFrom pops one entry and truncates excess beyond maxBytes (unlike TCP which does partial chunk reads) + - External UDP pattern: bind() locally, then bindExternalUdp() creates the host UDP socket and starts a recv pump (startUdpRecvPump) — sendTo checks for hostUdpSocket before routing externally + - MockHostUdpSocket with pushDatagram() controls the recv pump in tests; use setTimeout(r, 10) to allow pump microtasks to run +--- + +## 2026-03-23 - US-015 +- Implemented Unix domain sockets (AF_UNIX) with VFS integration in SocketTable +- bind() with UnixAddr creates a socket file in VFS (S_IFSOCK mode), connect() checks VFS path exists +- SOCK_STREAM: full data exchange, half-close, EOF propagation — reuses existing loopback data paths +- SOCK_DGRAM: message boundary preservation via sendTo/recvFrom, silent drop for unbound paths +- Always in-kernel routing — no host adapter involvement for Unix sockets +- EADDRINUSE when path exists in VFS (including regular files, not just socket entries) +- ECONNREFUSED when socket file removed from VFS (even if listeners map still has entry) +- Modified InMemoryFileSystem.chmod() to support explicit file type bits (S_IFSOCK | perms) +- bind() is now async (Promise) — all existing test files updated with await +- Files changed: packages/core/src/kernel/socket-table.ts (VFS option, async

packages/core/test/kernel/unix-socket.test.ts (new, 14 tests), 8 existing test files (async bind migration) +- **Learnings for future iterations:** + - bind() is now async like connect() and listen() — all callers must use await; sync throw tests must use .rejects.toThrow() + - InMemoryFileSystem.chmod() supports caller-provided type bits: if mode & 0o170000 is non-zero, the type bits are used directly; otherwise existing behavior preserved + - VFS is optional for SocketTable — Unix sockets still work via listeners map alone; VFS adds socket file creation and path existence checks + - Unix domain sockets share the listeners map with TCP for SOCK_STREAM, and udpBindings map for SOCK_DGRAM — addrKey() uses the path string as the key + - connect() for Unix addresses checks VFS existence before listeners map — this means removing the socket file (vfs.removeFile) causes ECONNREFUSED even if the listener entry still exists +--- + +## 2026-03-23 - US-016 +- Exposed SocketTable as a public property on KernelImpl +- KernelImpl constructor creates SocketTable with VFS reference +- onProcessExit hook calls socketTable.closeAllForProcess(pid) to clean up sockets on process exit +-

assertions + - Process exit cleanup chain: ProcessTable.markExited → onProcessExit callback → cleanupProcessFDs + socketTable.closeAllForProcess + - SocketTable constructor accepts { vfs } option — pass kernel's VFS for Unix domain socket file management + - dispose() order matters: terminateAll() first (triggers onProcessExit for each process), then disposeAll() for any remaining sockets, then driver teardown +--- + +## 2026-03-23 - US-017 +- Implemented TimerTable with per-process ownership, budget enforcement, and cross-process isolation +- KernelTimer struct: id, pid, delayMs, repeat,

packages/core/src/kernel/index.ts (exports), packages/core/test/kernel/timer-table.test.ts (new, 23 tests) +- **Learnings for future iterations:** + - TimerTable follows the same Map + nextId pattern as InodeTable and SocketTable + - Budget enforcement is inline in createTimer() — no separate enforceLimit() method needed; constructor option + setLimit() per-process override + - clearTimer without pid param allows unconditional clear (for kernel-internal cleanup); with pid enables cross-process isolation + - hostHandle is mutable on KernelTimer — callers set it after createTimer() returns,

onProcessExit callback +- getHandles() returns a defensive copy to prevent external mutation of kernel state +- Files changed: packages/core/src/kernel/types.ts (ProcessEntry fields), packages/core/src/kernel/process-table.ts (handle methods + cleanup), packages/core/test/kernel/process-table.test.ts (13 new tests, 41 total) +- **Learnings for future iterations:** + - Handle tracking is simpler than TimerTable — no separate class needed, just Map fields on ProcessEntry + methods on ProcessTable + - EBADF is the right error for unknown handle IDs (not ENOENT) — consistent with FD error conventions + - Handle cleanup in markExited() must happen before onProcessExit callback to ensure consistent state for downstream cleanup hooks + - kernel-integration.test.ts has 2

DnsCache is simpler than other kernel tables — no per-process ownership, no KernelError throws, just a TTL Map + - DnsResult type is imported from host-adapter.ts (address: string, family: 4|6) + - Lazy expiry: expired entries are removed on lookup, not by a background timer — keeps implementation simple + - vi.useFakeTimers()/vi.advanceTimersByTime() is the pattern for testing time-dependent

handler is dispatched; other signals can be purely handler-overridden + - SIGCHLD default action is "ignore" per POSIX — tests expecting driverProcess.kill(SIGCHLD) need a registered handler + - Recursive deliverPendingSignals can cause double-dispatch — check pendingSignals.has(sig) before dispatching from snapshot array + - deliverSignal → dispatchSignal → applyDefaultAction three-level

bridge handler keys (fdOpen, fdClose, fdRead, fdWrite, fdFstat, fdFtruncate, fdFsync, fdGetPath) to bridge-contract.ts +- Added buildKernelFdBridgeHandlers() in bridge-handlers.ts — creates FDTableManager + ProcessFDTable per execution, delegates I/O to VFS +- Wired FD handlers into execution-driver.ts dispatch handlers (routed through _loadPolyfill bridge dispatch) +- Replaced all

(buildKernelFdBridgeHandlers), packages/nodejs/src/execution-driver.ts (wiring + cleanup), packages/nodejs/src/bridge/fs.ts (fdTable removal, bridge call migration) +- **Learnings for future iterations:** + - Bridge globals not in the Rust V8 SYNC_BRIDGE_FNS are automatically dispatched through _loadPolyfill via BRIDGE_DISPATCH_SHIM — no Rust code changes needed for new bridge functions + - The dispatch shim JSON-serializes args and results, so binary data must be base64-encoded + - After modifying bridge source (bridge/fs.ts), the bridge IIFE must be rebuilt via `pnpm turbo run build --filter=@secure-exec/nodejs` for changes to take effect in tests + - FD operations (open/close/read/write/fstat) now go through the bridge dispatch; error messages must contain "EBADF"/"ENOENT" substrings for the in-isolate error wrapping to produce correct fs error codes + - ProcessFDTable from @secure-exec/core handles FD allocation, cursor tracking, and reference counting — bridge

Completed the `US-048` inode/VFS integration by wiring `kernel.inodeTable` into `KernelImpl` and `InMemoryFileSystem`, tracking stable inode IDs through file creation, stat, hard links, unlink, and last-FD cleanup +- Updated kernel FD lifecycle paths to keep inode-backed access alive after unlink via `FileDescription.inode`, including read/write, pread/pwrite, seek/stat, dup2 replacement, inherited FD overrides, and whole-process teardown +- Added inode integration coverage for real `ino`/`nlink`, deferred unlink readability, last-close cleanup, and `pwrite` on unlinked open files +- Unblocked package quality gates with a type-only isolate-runtime globals declaration fix and a PTY raw-mode bulk-write fix so oversized writes with `icrnl` enabled fail atomically with `EAGAIN` +-

and closes, then let the caller re-run `fdPoll()` to compute exact readiness bits +- Gotchas encountered +- Fixing `poll(-1)` only in the main-thread driver is insufficient because the worker RPC layer has its own 30s `Atomics.wait()` guard; indefinite polls need both sides to cooperate +- Useful context +- The new regression coverage lives in `packages/wasmvm/test/net-socket.test.ts` and
