From 0d064c76e58699d2cf917f60cebc50e2f516941c Mon Sep 17 00:00:00 2001 From: Thomas Vincent Date: Sun, 19 Apr 2026 23:14:23 -0700 Subject: [PATCH 01/53] feat(libuv): implement Spine 2.0 asynchronous engine This squashes the entire asynchronous architecture rewrite, including: - libuv event loop foundation and stage-based pipeline - Persistent PHP script server socket pool - PCRE2 JIT regex cache - Global OID multiplexing with WRR scheduling - Adaptive token-bucket governors - Safe libuv memory lifecycles and telemetry sink --- .clang-tidy | 10 + .clangd | 12 + .claude/settings.local.json |

Build with +the FreeBSD instructions; substitute `pkg` for DragonFly's package set. + +### Windows native (MSVC) + +Tier 3. A Windows port exists in `src/platform/platform_*_win.c`. The +build is exercised through the MSYS2/MinGW lane below.

Raise `LimitAS` in the systemd + unit if it was tuned down for a constrained host. +* `SystemCallFilter=@system-service` in the spine unit already blocks + most of the exotic syscalls hardened_malloc avoids calling, so the two + hardening layers do not conflict. +* LD_PRELOAD is cleared when spine execs a PHP script server; the child + runs with the stock allocator. That is fine: the attack surface that + matters for the PHP children is in the script they execute, not in the + malloc implementation. + +## musl + mimalloc (alternative) + +For distros built on musl libc (Alpine) mimalloc is the pragmatic choice +because musl's native allocator is already slab-based and hardened_malloc +expects glibc ABI details. The integration is identical (`LD_PRELOAD`); +see mimalloc's `docs/hardening.md` for the recommended environment +variable set. + +## scudo (Bionic / LLVM) + +Binaries built with `-fsanitize=scudo` get the Scudo allocator linked in +directly; no `LD_PRELOAD` is required. On Clang builds, adding +`-fsanitize=scudo` to `CFLAGS` at CMake configure time is sufficient. The +Scudo allocator is tuned for server workloads and is the default on +Android and on some Fuchsia configurations. + +## AppArmor profile scope + +`etc/apparmor.d/spine.apparmor.in` (rendered at install time to the +binary-attach-specific profile name) restricts spine's temp write +scope to `/tmp/spine.*`. A prior `/tmp/** rw` catch-all was removed +because it let spine read or replace any other service's temp files +(e.g. PostgreSQL's socket lockfile, sshd's auth temp spools). If a +Cacti script genuinely needs its own /tmp scratch path, grant the +narrower prefix it uses rather than widening the profile. + +The profile also carries explicit `deny /root/** rwklx,` and +`deny /etc/shadow* rwklx,` rules. AppArmor deny-on-match wins over any +later permit, so a future edit that re-adds `/` or `/etc/**` cannot +silently expose those paths. + +## Coordination with the sandbox + +`spine_sandbox_restrict()` applies seccomp-bpf and Landlock after the +DB and SNMP sessions are open. hardened_malloc does its own `mprotect`, +`mmap`, and `madvise` calls for guard pages and slab rotation; all three +syscalls are on the spine seccomp allowlist.

Any dereference of `watcher` after ares_process_fd is UAF. The current code happens to read fields only before the call, but there is no comment documenting that invariant and a future refactor would break it silently.

An async query that arrives between the flush drain and the db close would succeed at submission, then fire its callback after the handle was freed - use-after-free. Add a process-wide shutdown fence: - spine_async_mysql_shutdown_begin() flips a volatile flag; new queries via spine_async_mysql_query return -ESHUTDOWN. - In-flight queries keep their existing uv_poll chain so the uv_run drain completes them normally. - Non-HAVE_MYSQL_ASYNC build provides the symbol as a no-op so callers in spine.c do not need the compile-time guard. Spine calls the fence immediately before the batch flush so the flush's own callbacks still run, and then no further submissions are possible while the drain is in progress.

The reap pass only fired from spine_cb_record. On an idle daemon (no poll failures), the reap never ran and old entries from a prior failure burst sat in the hash for the process lifetime. Add the same reap call to spine_cb_should_skip, which is invoked every cycle for every host. Rate limiting via SPINE_CB_REAP_INTERVAL already prevents thrash. 2. The reap sweep held the table mutex O(N). A large unhealthy population stalled other threads. Add SPINE_CB_REAP_BATCH (256) cap; unscanned entries wait for the next sweep. 3. Tests could not drive the reap deterministically because it used time(2). Add spine_cb_set_clock_for_test(fn) and thread the clock through every time(NULL) caller via spine_cb_clock().

Single-threaded today, but a future refactor that walks the loop from a worker thread would race on increment. Switch to _Atomic int with relaxed-order fetch_add; this is only an operator diagnostic so no synchronisation guarantees are required beyond 'no lost increments'. - g_async_mysql_shutting_down was a plain volatile int. Worker threads on weakly-ordered architectures (ARM, POWER) might observe stale 0 after the main thread sets it. Switch to atomic_int with explicit release on the set and acquire on the read so the happens-before ordering is enforced across thread boundaries.

Add matching add_executable + add_test entries with the correct link libraries and source-file dependencies. HIGH: test_async_exec_shell.c now reads SPINE_SOURCE_ROOT from a compile-time define set by CMake to CMAKE_SOURCE_DIR, so the source- scan works from any ctest CWD rather than relying on 'run from project root'. HIGH: add spine_async_mysql_shutdown_reset_for_test so unit tests can flip the fence more than once. Production callers must not use this; the production fence stays a one-way latch. HIGH: replace ASSERT_TRUE(count >= 0) tautology in the shutdown test with a before/after delta and build-matrix-aware expected values (HAVE_MYSQL_ASYNC bumps the counter by 1; fallback leaves it zero). HIGH: add a source-scan test that asserts spine_async_batch_flush() appears before spine_async_mysql_shutdown_begin() in spine.c. Reversing the order silently drops the pending batch at shutdown and now fails the test. HIGH: spine_uv_run_bounded caps each shutdown drain at 3 wall-clock seconds. Three previously-unbounded uv_run(UV_RUN_DEFAULT) calls could hang shutdown indefinitely on a wedged callback. MEDIUM: spine_cb_init resets spine_cb_last_reap so tests cycling init/shutdown/init under a rewound mock clock do not carry stale reap-cadence state forward.

Define SPINE_SHUTDOWN_DRAIN_SECS next to spine_uv_run_bounded and point the async_dns comment at it. The helper no longer takes a seconds parameter - every caller wants the same budget. KISS: drops four repeated '(loop, 3)' call-site arguments in spine.c in favour of a single-argument helper. Behaviour unchanged.

A typo in the DB silently resets a setting to zero. - Integer overflow is undefined behaviour on C99+. A value of "9999999999" invokes UB on 32-bit int platforms. - No distinction between "0" and "bogus". spine_atoi uses strtol with errno detection: ERANGE clamps to INT_MAX / INT_MIN rather than wrapping, non-numeric input (end == s) returns 0 preserving the original contract for callers that already treat 0 as 'use default'. 20 call sites in util.c swapped.

A config value of '-9999999999999999999' silently became INT_MAX, a sign-flip that corrupts every setting passed through it. Split the ERANGE branch on sign so overflow in either direction clamps to the matching bound. Renamed to spine_parse_int so 'grep atoi' is no longer ambiguous. HIGH: new test CMake entries linked only against spine_hardening. util.c / circuit_breaker.c / async_mysql.c transitively depend on mysql, net-snmp, and libaudit; without linking them, the test binaries fail the undefined-reference stage. Add spine_mysql, spine_netsnmp, Threads, and the conditional audit target to every new test target. Call spine_require_mysql / spine_require_netsnmp first to register those INTERFACE libraries. HIGH: atomic-style consistency. g_spine_uv_leaked_handles was _Atomic int while the other atomics used atomic_int / atomic_ulong. Switch to atomic_int so every counter matches the stdatomic.h typedefs. MEDIUM: spine_uv_run_bounded now measures the deadline with uv_hrtime (monotonic nanoseconds) instead of time(2), so the 3- second budget is real sub-second resolution rather than the 0-1s jitter time(2) produces. MEDIUM: PATH_MAX fallback for AIX/HP-UX builds that leave it undefined. 4096 matches Linux default. MEDIUM: shutdown metrics log line. One SPINE_LOG at teardown prints libuv_leaked, cb_entries, cb_trips, cb_reaped, and mysql_refused_after_shutdown. Grep-friendly for operators without a telemetry endpoint. LOW: SPINE_SHUTDOWN_DRAIN_SECS moved to src/spine_shutdown.h so spine.c and async_dns.c share the constant. Raising the budget in one place updates every subsystem. LOW: test_async_mysql_shutdown uses a real uv_loop_init rather than a synthetic (uv_loop_t *)1. Future refactor that dereferences the loop before the fence check now fails cleanly against an empty loop instead of segfaulting.
