OpenBSD ships its own libc fork with +strict POSIX semantics; the same BSD code paths used for FreeBSD apply. +`pledge(2)` and `unveil(2)` integration is fully implemented in +`src/platform/platform_sandbox_openbsd.c`, providing robust syscall and +filesystem confinement when running as a non-root user. + +### DragonFly BSD 6.x + +Tier 3.

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. Native MSVC builds +are possible via the `ci-smoke` preset but full polling has not been +verified end-to-end against a Windows Cacti install. + +### Windows MSYS2/MinGW + +Tier 3. CI lane runs `cmake --preset ci-smoke` which exercises the +platform abstraction without the Net-SNMP stack (Net-SNMP is not currently +packaged for MINGW64). Treat Windows results as a portability signal, not +a release target. + +```sh +pacman -S --needed \ + mingw-w64-x86_64-gcc mingw-w64-x86_64-cmake mingw-w64-x86_64-ninja \ + mingw-w64-x86_64-libmariadbclient mingw-w64-x86_64-openssl pkg-config +cmake --preset ci-smoke +cmake --build --preset ci-smoke +``` + +### UBI 9 / RHEL 9 + +Tier 3. RHEL 9 itself is not in CI because the image requires a paid +subscription. Three options exist for testing on RHEL 9: + +1. **Rocky 9 / Alma 9** (Tier 1). Use these for day-to-day work. +2. **UBI 9** (Universal Base Image, free, no subscription). Advisory CI + lane via `registry.access.redhat.com/ubi9/ubi`. Package set is + restricted; `mariadb-connector-c-devel` may not be reachable without + paid repos, so the lane is `continue-on-error: true`. +3. **Red Hat Developer Subscription**. Free for individual developers at + . Grants full RHEL 9 ISO and repo + access. Use in a local VM when a RHEL-specific regression is reported. + +Local Docker reproduction: + +```sh +bash scripts/test-distros.sh registry.access.redhat.com/ubi9/ubi +``` + +--- + +## Tier 4 — Experimental + +Compile-time scaffolding exists but no runtime verification has been +performed. No CI lane. These platforms have known-good build paths in +`CMakeLists.txt` and source-level guards in `src/`, but there is no +hardware in the lab and no community runner.

The +Scudo allocator is tuned for server workloads and is the default on +Android and on some Fuchsia configurations. + +## 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. If the allowlist ever +narrows, keep those three entries regardless of whether hardened_malloc +is in use - they are hot in glibc's default allocator as well. diff --git a/docs/security-selinux.md b/docs/security-selinux.md new file mode 100644 index 00000000..9ddc1edf --- /dev/null +++ b/docs/security-selinux.md @@ -0,0 +1,67 @@ +# SELinux enablement + +Spine ships an SELinux policy module skeleton under `etc/selinux/`.
