Link-local destinations get a sin6_scope_id resolved from the first non-loopback v6 interface when the caller did not supply a %zone suffix. Each echo now carries a SPINE_PING_MAGIC + pid_mask signature so a reply that happens to match id+seq but originates from an unrelated flow is still dropped. Receive paths bounds-check before the struct cast, reject undersized packets, and verify source, id, seq, and payload signature in that order. getaddrinfo in resolve_sockaddr now sets AI_NUMERICHOST when the hostname is a numeric literal so a crafted dotted-quad lookalike cannot steer the resolver into DNS. CAP_NET_RAW drop is wired behind HAVE_LIBCAP but deferred at the call site because spine opens raw sockets on demand per ping; a future persistent-socket refactor can enable the call unchanged. Numeric-address oneshot helpers at the bottom of ping.c back the platform_icmp facade without duplicating the capability dance.

Oneshot helpers recompute remaining timeout each loop, so a flood of mismatched replies cannot extend the deadline. 2. Windows loader publishes function pointers with MemoryBarrier() before InterlockedExchange(&g_load_ok, 1), fixing the ARM64 race where a waiter could observe g_load_ok=1 with NULL fn pointers. Waiter now gates on g_load_ok alone. 3. Windows facade handles payload==NULL by building a default signature (matches POSIX behaviour) and rejects the degenerate NULL+len>0 case before forwarding to iphlpapi.dll. 4. Bare free() in cleanup paths replaced with SPINE_FREE() per project convention.

The three TUs that touched the on-wire format (ping.c, ping_validate.c, platform_icmp_win.c) now all include this header so a future edit cannot silently drift. - Numeric-address oneshot helpers now call spine_ping_validate_payload() on replies when the facade owns payload composition (payload argument was NULL). Closes the gap where spine_icmp_echo_v4/v6 were weaker than the host_t-driven path at rejecting LAN spoofs. - Replace remaining bare free() with SPINE_FREE() in ping.c and a local equivalent (SPINE_ICMP_FREE) in the Windows facade TU. - Reply-validation test uses the shared wire header and checks sizeof(spine_ping_payload_t) == 16 at runtime.

On macOS, Windows, and minimal Linux without libsystemd, sd_notify calls become no-op stubs and the build is unchanged. Runtime: - READY=1 published once main initialization completes. - WATCHDOG=1 emitted from the poller cycle so systemd can restart a hung instance via WatchdogSec=120 in the unit. - STOPPING=1 with status text on graceful shutdown. - STATUS= updated periodically with cycle and host counts. - SIGHUP triggers RELOADING=1, re-reads spine.conf, then re-publishes READY=1 with a fresh MONOTONIC_USEC. Unit (etc/systemd/spine.service): - Type=notify with NotifyAccess=main, Restart=on-failure. - Drops to dedicated spine user/group; AmbientCapabilities=CAP_NET_RAW is the only privilege. - Hardening: NoNewPrivileges, ProtectSystem=strict, ProtectHome, ProtectKernel*, ProtectClock, ProtectHostname, RestrictNamespaces, RestrictRealtime, RestrictSUIDSGID, LockPersonality, MemoryDenyWriteExecute, SystemCallArchitectures=native, SystemCallFilter=@system-service excluding @privileged @resources, RestrictAddressFamilies=AF_INET AF_INET6 AF_UNIX AF_NETLINK. - ReadWritePaths scoped to /var/log/cacti and /var/run/spine only. - Journal logging via StandardOutput=journal. Companion etc/systemd/spine.timer drives 5-minute polls when spine is deployed without an external scheduler. Install paths use systemd's pkg-config systemdsystemunitdir variable with /lib/systemd/system as the LTS-distro fallback.

From 6ccf270e2c07ad562f73cdbfe9717e2f89e2f5ac Mon Sep 17 00:00:00 2001 From: Thomas Vincent Date: Tue, 14 Apr 2026 18:14:29 -0700 Subject: [PATCH 099/195] docs(platforms): order Tier 1 by Cacti deployment footprint Reorder Tier 1 to lead with the Red Hat lineage (RHEL 9 / Rocky 9 / Alma 9 / Oracle Linux 9), which has the largest Cacti deployment footprint in enterprise, telecom, banking, and government. Ubuntu LTS, Debian, Fedora, and macOS follow in approximate market-share order. Rocky 9 and Alma 9 are authoritative CI proxies for RHEL 9; the RHEL image itself requires a paid subscription. UBI 9 remains a Tier 3 advisory lane because its restricted package set cannot reach a full build without subscription repos. Also consolidate the Tier 1 table into a single RHEL 9 row covering RHEL / Rocky / Alma / Oracle Linux since they share the same install command and behave identically for spine.

The perf-regression SNMP simulator benchmark silently proceeded to hyperfine when snmpd never came up, leaving hyperfine to fail on an unresponsive port without diagnostics. Track a ready flag, fail the step with snmpd.log dumped, so future regressions show the root cause instead of a generic 'Command terminated'.

Add the file as empty so codespell runs and reports any spelling hits without aborting on missing config. - scan-build: --plist was removed in modern clang-tools (Ubuntu 24.04 ships scan-build that no longer accepts the flag). --output alone produces the HTML report we already upload. - shfmt: applied -i 2 -ci to debug, package, packaging/debian/postinst, scripts/test-*.sh. No semantics changed; whitespace only. Also fixed actionlint SC2035 in release.yml: 'ls -la *.tar.gz' -> './*.tar.gz'.

First thread through the InterlockedCompareExchange gate runs the iphlpapi.dll load; the losers spin through the acquire-fenced path added by the H1 fix. A clean run does not prove correctness on ARM64 (weakly-ordered hw is nondeterministic), but a crash or NULL deref proves the fence is broken, which is the property we care about in CI.

ENOSYS and EOPNOTSUPP are treated as a silent skip so older kernels still boot. * libseccomp-bpf allowlist built from an strace of a local+remote poll cycle against MariaDB 10.11 and net-snmp 5.9. Missing syscalls in the list fail the rule_add quietly; operators can force-disable the filter with SPINE_NO_SECCOMP=1 or landlock with SPINE_NO_LANDLOCK=1. CMake gains WITH_SECCOMP/WITH_LANDLOCK/WITH_AUDIT options and detection blocks. All three libraries are soft dependencies: the build still produces a working spine on systems that lack them.

None are async-signal-safe, so a SIGSEGV mid-allocation could deadlock inside libc. Pre-format per-signal messages at startup, emit with write(2), and use _exit(128 + signo) on SIGSEGV/SIGBUS/SIGFPE/ SIGABRT to skip atexit handlers. Drop SIGPIPE from the fatal set and ignore it process-wide so a poll script closing stdout early no longer kills spine. Remove the redundant legacy signal() loop.

Decode the Cacti hex-string form at DB load time, carry bytes + length in target_t and host_t, and pass both to snmp_host_init(). The hex path stays as a transitional fallback.

The integration fixtures shipped the file at the COPY/checkout default of 0644, which H1 correctly rejects. Dockerfile: add RUN chmod 0600 after the COPY so the baked conf (owned by root, mode 0600) satisfies both H1 checks. This fixes the Docker Integration Tests, Poll Timing Benchmark, and build-cmake-linux- sanitizers jobs that use the production image without a bind-mount override. docker-compose.yml: the bind-mount of tests/snmpv3/spine/spine.conf arrives at 0644 from the git checkout and cannot be chmod'd through a :ro mount. Switch to a staging mount at spine.conf.src, set user: "0:0" so the process euid is root, and add a wrapper entrypoint that installs the staged conf to /tmp/spine.conf at 0600 before exec-ing spine. ci.yml / distro-matrix.yml: add chmod 0600 tests/snmpv3/spine/spine.conf before the cmake build in both FreeBSD jobs so ctest passes on FreeBSD 14 (Tier 1).
