Adds FreeBSD as a supported platform. The daemon, fipsctl, TUN datapath and
DNS integration build and run there, with a native pkg and an rc.d service.
The one piece of genuinely new datapath logic is the TUN framing. FreeBSD's
tun rejects every non-IPv4 packet with EAFNOSUPPORT unless TUNSIFHEAD is set,
so nothing IPv6 can be sent at all; with it set, every frame carries a 4-byte
network-order address-family prefix the way macOS utun does. The ioctl is
issued at device creation and the prefix is stripped on read, which gives
callers the same raw-IP contract as Linux and macOS. A frame carrying only
the header reads as zero bytes and the reader loops treat it as nothing to
do. The address family is now taken from libc rather than hardcoded, because
AF_INET6 is 30 on Darwin and 28 on FreeBSD.
The reader shutdown path, the writer's address-family header and the
supervisor's shutdown pipe were all macOS-only and are now shared with
FreeBSD, since neither platform wakes a blocked read when the interface goes
down. Linux continues to rely on interface deletion.
mdns-sd moves from 0.19 to 0.20 for socket-pktinfo 0.4.1, the first release
that builds on FreeBSD, which uses IP_RECVDSTADDR and IP_RECVIF instead of
Linux-style IP_PKTINFO. This is the only change here that affects every
platform rather than just the new one.
The config, ACL, hosts and keygen path constants now treat FreeBSD the same
as macOS, since both install under /usr/local/etc/fips. Those constants
arrived separately on maint and are merged here rather than duplicated: the
predicates widen to cover FreeBSD, the platform-gated tests widen with them,
and keygen keeps reading the shared SYSTEM_CONFIG_DIR constant rather than
reintroducing a literal.

Add OpenWrt .apk packaging for OpenWrt 25+, where apk-tools is the
mandatory package manager. The existing .ipk continues to cover OpenWrt
24.x and earlier. Built SDK-free like the .ipk: it reuses the
cargo-zigbuild cross-compile and the shared installed-filesystem payload
under openwrt-ipk/files, and assembles the ADB container with the
official `apk mkpkg` applet from apk-tools 3.0.5 built from source, so no
OpenWrt SDK image is needed.
The package-openwrt workflow is refactored so a single compile-binaries
job cross-compiles and strips each arch once; both the .ipk and .apk
packagers consume the binaries via a new --bin-dir flag instead of each
recompiling. A build-apk job (aarch64, x86_64) builds apk-tools,
packages, and structurally verifies the .apk with `apk adbdump`. Releases
now publish .apk artifacts and checksums alongside .ipk; the release
download is scoped to fips_* so the shared raw-binary artifacts are not
swept into the published release. apk-version.sh maps a release tag or
commit height to an apk-tools-valid version, covered by a case-table test.
Packages are unsigned, installed with `apk add --allow-untrusted`,
matching the .ipk posture.
Also fix the OpenWrt control socket: the init script now pre-creates
/run/fips before starting the daemon, the procd equivalent of the systemd
unit's RuntimeDirectory=fips. Without it, on a fresh boot the daemon
resolves its control socket to /tmp (since /run/fips does not yet exist),
while fips-gateway later creates /run/fips for its own gateway.sock,
leaving fipsctl/fipstop resolving a /run/fips/control.sock the daemon
never bound.
Add a flake that builds all four binaries (fips, fipsctl, fips-gateway,
fipstop) on Linux and macOS, pinning the exact toolchain from
rust-toolchain.toml (1.94.1 + rustfmt/clippy) via fenix so Nix builds
match CI and the AUR/Debian packaging.
Wire up the build-time native deps the source tree needs: pkg-config and
bindgenHook (libclang) for the rustables/libdbus-sys bindgen step, and
dbus for bluer's BLE support. autoPatchelfHook rewrites the binary RPATHs
so the daemon resolves libdbus-1.so.3 and libgcc_s.so.1 from the Nix store
at runtime — without it `fips` fails to load on NixOS, which has no global
/usr/lib.
Outputs: packages.{default,fips}, apps for each binary, checks.fips, and a
devShell with the pinned toolchain plus cargo-edit. Tests are skipped in
the package build since they exercise TUN devices, raw sockets, and mDNS
that aren't available in the sandbox, mirroring the AUR/Debian packaging.
Verified end-to-end in a pure Nix store (nixos/nix container): nix build,
nix flake check, and running all four binaries succeed against the
committed flake.lock.
Documented across the install and developer docs: a Nix / NixOS section in
packaging/README.md, the from-source guide in docs/getting-started.md
(noting the flake produces binaries only, with NixOS system integration
through the system configuration rather than the installer), the CHANGELOG,
README, CONTRIBUTING, and the v0.4.0 release notes.

Linux source builds pull in rustables, whose build script runs bindgen
to generate nftables bindings for the LAN gateway. bindgen needs
libclang.so on the build host, so a clean source build fails with
'Unable to find libclang' unless libclang-dev (or llvm) is installed.
The prerequisite text in README.md and CONTRIBUTING.md previously
listed only the optional BLE dependencies, and packaging/README.md had
no source-build prerequisite list at all. Document libclang-dev as a
mandatory Linux build dependency, distinct from the optional BLE deps,
and note that it is build-time only so pre-built .deb installs are
unaffected.
Installing /etc/fips/fips.yaml as a live dpkg conf-file collides with a
configuration-management-rendered or operator-edited config on upgrade:
dpkg either prompts interactively (keep/replace), stalling unattended
upgrades, or clobbers the local file. Ship the default config as
/usr/share/doc/fips/fips.yaml.example (mode 644) and drop it from
conf-files. postinst now seeds /etc/fips/fips.yaml from the example only
when it does not already exist (mode 600), yielding to any existing
config without a prompt or clobber. Add ConditionPathExists for the
config to the service unit so a missing config skips the unit cleanly
rather than crash-looping.
Gate platform-specific code behind cfg attributes and add full Windows
support: TUN device via wintun, TCP control socket on localhost:21210,
Windows Service lifecycle (--install-service/--uninstall-service/--service),
CI build and test matrix, and packaging with ZIP builder and PowerShell
service management scripts.
Key changes:
- Cargo.toml: move tun/libc/rtnetlink behind cfg(unix); add wintun and
windows-service dependencies for Windows
- upper/tun.rs: wintun-based TUN implementation with netsh configuration
for IPv6 address, MTU, and fd00::/8 routing
- control/mod.rs: split into unix_impl/windows_impl; Windows uses TCP on
localhost:21210 with shared connection handler
- bin/fips.rs: refactor main() into run_daemon() accepting a shutdown
signal; add Windows Service support via windows-service crate
- transport/udp/socket.rs: platform-gated modules; Windows uses
tokio::net::UdpSocket (kernel drop count unavailable, returns 0)
- transport/ethernet: gate to cfg(unix); add Windows stub types
- config: platform-conditional default paths (socket, hosts) for Windows
- CI: add windows-latest to build matrix and test-windows job with
cargo-nextest
- packaging/windows: build-zip.ps1, install-service.ps1,
uninstall-service.ps1, and package-windows.yml workflow
- README/docs: Windows build instructions, service management, and
control socket platform differences
Linux and macOS behavior is unchanged.
macOS platform:
- Platform-native TUN interface management with shutdown pipe
- Raw Ethernet transport with macOS socket backend (socket_macos.rs)
- EthernetTransport and TransportHandle::Ethernet ungated from Linux-only
- macOS .pkg packaging (build-pkg.sh, launchd plist, uninstall script)
- CI: macOS build and unit test jobs; x86_64 cross-compiled from
macos-latest via rustup target add x86_64-apple-darwin
Gateway feature flag:
- New opt-in `gateway` Cargo feature activates optional `rustables` dep
- `pub mod gateway` and `Config.gateway` gated behind the feature so
macOS builds never pull in Linux-only nftables bindings
- `fips-gateway` bin has `required-features = ["gateway"]`
- All Linux/OpenWrt/AUR packaging passes `--features gateway`
CI / packaging:
- package-linux, package-macos, package-openwrt now trigger on push to
master/maint/next and on pull requests; release uploads remain tag-gated
- Bloom filter routing fix: fall through to tree routing when no candidate
is strictly closer
- MMP intervals: raise MIN to 1s / MAX to 5s with 5-sample cold-start phase
