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.

FIPS Packaging
This directory contains packaging for all supported target platforms.
All build outputs go to deploy/ at the project root.
Quick Start
make deb # Debian/Ubuntu .deb
make tarball # systemd install tarball
make ipk # OpenWrt .ipk (opkg, OpenWrt 24.x and earlier)
make apk # OpenWrt .apk (apk-tools, mandatory on OpenWrt 25+)
make aur # Arch Linux AUR package (fips-git, local build + namcap)
make pkg # macOS .pkg installer
make freebsd # FreeBSD .pkg package (on FreeBSD; use gmake)
make zip # Windows .zip package
make all # deb + tarball (default)
Build Prerequisites
These targets build FIPS from source, so the host needs a build
environment in addition to a Rust toolchain (the version pinned in
rust-toolchain.toml is auto-installed by rustup).
On Linux, libclang is required: the LAN gateway's nftables
bindings are generated by bindgen at build time, which needs
libclang.so on the build host. Without it the build fails inside the
rustables crate with an "Unable to find libclang" error.
sudo apt install libclang-dev # Debian / Ubuntu
This is a build-time prerequisite only — it is not a runtime
dependency, so hosts installing a pre-built .deb do not need it.
BLE support is optional and, when building with it, additionally needs
bluez, libdbus-1-dev, and pkg-config; the build picks up BLE if
those are present and skips it cleanly if not.

Formats
Debian/Ubuntu (.deb)
Built with cargo-deb. Installs
fips, fipsctl, and fipstop to /usr/bin/, and enables the systemd
service.
The default configuration ships as an example at
/usr/share/fips/fips.yaml.example and is not a dpkg conf-file.
(It is deliberately not under /usr/share/doc, which minimal and
container installs path-exclude, since the postinst reads it at install
time.)
On install, postinst seeds /etc/fips/fips.yaml (mode 600) from the
example only if it does not already exist, so a configuration that
was rendered by configuration management or edited by an operator is
never prompted for or clobbered on upgrade. To reset to defaults, remove
/etc/fips/fips.yaml and reinstall, or copy the example back manually.
# Build
make deb
# Install
sudo dpkg -i deploy/fips_<version>_<arch>.deb
# Remove (preserves config and keys)
sudo dpkg -r fips
# Purge (removes config and identity keys)
sudo dpkg -P fips
systemd Tarball
A self-contained tarball with binaries and an install.sh script for
any systemd-based Linux distribution.
# Build
make tarball
# Install (on target host)
tar -xzf deploy/fips-<version>-linux-<arch>.tar.gz
sudo ./fips-<version>-linux-<arch>/install.sh
See systemd/README.install.md for full installation and configuration instructions.
OpenWrt (.ipk, opkg — OpenWrt 24.x and earlier)
Cross-compiled with cargo-zigbuild and assembled as a standard .ipk
archive. Supports aarch64, mipsel, mips, arm, and x86_64 targets.
# Build (default: aarch64)
make ipk
# Build for a specific architecture
bash packaging/openwrt-ipk/build-ipk.sh --arch mipsel
See openwrt-ipk/README.md for router-specific installation instructions.
OpenWrt (.apk, apk-tools — mandatory on OpenWrt 25+)
OpenWrt 25 makes apk-tools the mandatory package manager (it is opt-in on
24.10). Same SDK-free approach
(cargo-zigbuild), but the .apk container is assembled by apk mkpkg
rather than hand-rolled, so the build additionally needs an apk-tools v3
apk binary built from source. The installed-filesystem payload is shared
with the .ipk package.
# Build (default: aarch64; also x86_64)
make apk
# Build for a specific architecture
bash packaging/openwrt-apk/build-apk.sh --arch x86_64
Packages are unsigned; install with apk add --allow-untrusted. See
openwrt-apk/README.md for building apk-tools and
router-specific installation.
macOS (.pkg)
Built with pkgbuild (included with Xcode command-line tools). Installs
binaries to /usr/local/bin/, config to /usr/local/etc/fips/, sets up
the /etc/resolver/fips DNS resolver for .fips domains, and loads a
launchd daemon. The TUN device is named utun<N> (kernel-assigned)
rather than fips0.
# Build
make pkg
# Install
sudo installer -pkg deploy/fips-<version>-macos-<arch>.pkg -target /
# Remove
sudo packaging/macos/uninstall.sh
FreeBSD (.pkg)
Built natively on a FreeBSD host with pkg create. Ships fips,
fipsctl, and fipstop (fips-gateway is excluded — its NAT backend
is nftables, Linux-only), rc.d services, and .fips DNS integration
for local_unbound, unbound, or dnsmasq. Config installs
sample-style under /usr/local/etc/fips/ (edits survive upgrades).
# Build (on FreeBSD; this Makefile needs GNU make — pkg install gmake)
gmake freebsd
# or directly, no gmake needed:
./packaging/freebsd/build-pkg.sh
# Install
pkg add ./deploy/fips-<version>-freebsd-<arch>.pkg
sysrc fips_enable=YES fips_dns_enable=YES
service fips start
service fips_dns start
See freebsd/README.md for host resolver setup and field-tested caveats.
Windows (.zip)
A ZIP archive containing binaries, default config, and PowerShell service helper scripts. Requires the wintun driver for TUN support.
# Build
make zip
# Or directly
powershell -File packaging/windows/build-zip.ps1
# Extract and install as service (requires Administrator)
Expand-Archive deploy\fips-<version>-windows-x86_64.zip -DestinationPath fips
cd fips
powershell -File install-service.ps1
# Uninstall (preserves config)
powershell -File uninstall-service.ps1
# Uninstall and remove config
powershell -File uninstall-service.ps1 -RemoveAll
Arch Linux (AUR)
Two AUR packages are maintained: fips (release, builds from tagged
tarball) and fips-git (development, builds from latest git master).
# Build and validate locally (git variant)
make aur
# Install from AUR
yay -S fips-git # development build from master
yay -S fips # release build from latest tag
See aur/README.md for AUR publication instructions and maintainer guide.
Nix / NixOS (flake)
A flake at the project root builds all four binaries
(fips, fipsctl, fips-gateway, fipstop) from source. It pins the
exact toolchain from rust-toolchain.toml via
fenix and wires up the
build-time native dependencies (libclang for bindgen, plus dbus
and pkg-config for BLE), so it needs no system setup beyond Nix with
flakes enabled.
nix build .#fips # build the package (all four binaries)
nix run .#fips -- --help # run a binary directly
nix run .#fipsctl -- status
nix develop # dev shell with the pinned toolchain + cargo-edit
nix flake check # build + validate the flake
Add to a NixOS configuration via the flake's packages.<system>.fips
output, e.g. environment.systemPackages = [ fips.packages.${system}.default ];.
Shared Assets
common/ contains assets used across packaging formats:
fips.yaml— default configuration (ephemeral identity, UDP/TCP/TUN/DNS)hosts— static hostname-to-npub mappings for.fipsDNS resolution
