The generic systemd install tarball is the catch-all install path
for systemd Linux distros that don't have a per-format package
(Fedora, RHEL/CentOS, openSUSE, Alpine, etc.). It had drifted
behind the .deb and AUR packages and was missing fips-gateway, the
mesh-interface firewall baseline, and the multi-backend DNS helper
in the shipped tarball. Bring it to parity:
- New `packaging/systemd/fips-gateway.service` (clone of the .deb
unit; ExecStart pointed at `/usr/local/bin/fips-gateway`). Not
enabled at install time; operator opt-in.
- New `packaging/systemd/fips-firewall.service` (clone of the .deb
unit; nft path unchanged at `/usr/sbin/nft`). Not enabled at
install time; operator opt-in.
- `build-tarball.sh` now bundles the `fips-gateway` binary, the two
new units, the `fips.nft` baseline conffile, and the
`fips-dns-setup` / `fips-dns-teardown` multi-backend helpers from
`packaging/common/`.
- `install.sh` now installs `fips-gateway` to `/usr/local/bin/`,
installs both new units to `/etc/systemd/system/` (without
enabling them), preserves `/etc/fips/fips.nft` on upgrade like
`fips.yaml`, and creates the `/etc/fips/fips.d/` operator drop-in
directory. Post-install messaging mentions both opt-in services.
- `uninstall.sh` stops and disables the optional services in
dependency order (firewall, gateway, dns, daemon), removes the
new unit files, and removes the gateway binary. `--purge` already
handles `/etc/fips/` removal which covers `fips.nft` and
`fips.d/`.
- `README.install.md` documents all of the above: expanded
"What Gets Installed" table, new sections covering the firewall
baseline and the LAN gateway, refreshed DNS section reflecting
the multi-backend setup helper (systemd dns-delegate /
systemd-resolved drop-in / per-link resolvectl / dnsmasq /
NetworkManager-dnsmasq), and updated Service Management.
Also fixes a latent packaging bug: `install.sh` previously
referenced `${SCRIPT_DIR}/../common/fips-dns-setup`, a path that
exists only in the source-repo layout and not in the extracted
tarball. The script now resolves the helper from the staging
directory first (the tarball case), falling back to the source-repo
relative path. Bug latent since the multi-backend DNS helpers
landed.
CHANGELOG `[Unreleased]` documents the parity bump under Changed
and the path-resolution fix under Fixed.
Closes the longest-standing parity gap for non-Debian / non-Arch
systemd Linux distros installing from the release-distribution
tarball.
Drop the `tui`, `ble`, and `gateway` cargo features and replace
them with platform cfg gates. Plain `cargo build` now produces
every subsystem appropriate for the target platform with no
feature flags required.
Motivation:
- `default = ["tui", "ble"]` broke `cargo build` on macOS and
Windows because `ble` pulled in `bluer` (BlueZ, Linux-only).
Every non-Linux packager needed `--no-default-features`.
- The feature flags on `ble` and `gateway` were redundant with
their platform-gated deps (`bluer`, `rustables`). The parallel
gating was inconsistent and error-prone.
- `tui` feature protected against a ratatui binary-size concern
that no longer applies in 2026.
Cargo.toml:
- Remove `tui`, `ble`, `gateway` features; `default = []`.
- Promote `ratatui` to a non-optional top-level dependency.
- Move `rustables` from top-level optional into the Linux
target block, non-optional.
- Split `bluer` into its own target block with
`cfg(all(target_os = "linux", not(target_env = "musl")))`
— BlueZ isn't available on musl router targets and
`libdbus-sys` doesn't cross-compile to musl without pkg-config
sysroot setup.
- Drop `required-features` from the `fipstop` and `fips-gateway`
`[[bin]]` entries.
build.rs:
- Emit a `bluer_available` custom cfg when `target_os == "linux"`
and `target_env != "musl"`, for use in place of the verbose
full predicate in source cfg gates.
Source:
- Replace every `#[cfg(feature = "gateway")]` with
`#[cfg(target_os = "linux")]`. Gateway code works on both
glibc and musl Linux (rustables is fine on musl).
- Replace every `#[cfg(feature = "ble")]` with
`#[cfg(bluer_available)]`. BLE-specific code (BluerIo module,
bluer type conversions, BLE transport instance creation,
resolve_ble_addr) is excluded on musl and non-Linux. Generic
`BleAddr`, `BleIo` trait, `MockBleIo`, and `BleTransport<I>`
still compile on all targets.
- `src/bin/fips-gateway.rs`: always compiled, but `main()` is
gated to Linux. Non-Linux stub exits 1 with a diagnostic.
Existing non-Linux packaging scripts don't ship it, so the
stub binary sits unused.
Packaging and CI:
- Drop `--features` and `--no-default-features` flags from every
packaging script and workflow. Defaults now match each
platform's capabilities.
- AUR `fips-git` automatically aligns with stable `PKGBUILD`
(both build with defaults).
Verified: `cargo build --release` with no flags produces all
four binaries on glibc Linux; all unit and integration tests
pass across Linux/macOS/Windows/OpenWrt (musl) in CI.
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
- Add package-linux.yml: builds tarball and .deb for x86_64 and aarch64
on v* tag push, uploads artifacts to GitHub release with checksums
- Make build-tarball.sh target-aware: --target, --version, --arch, --no-build
- Make build-deb.sh target-aware: --target, --version, --no-build
- Configurable strip binary via STRIP env var
build-tarball.sh only applied --mtime when SOURCE_DATE_EPOCH was
explicitly set, and did not sort tar entries. This produced different
tarballs across builds due to varying timestamps and filesystem
ordering. Default SOURCE_DATE_EPOCH to the git commit timestamp and
add --sort=name for deterministic output.
Pin Rust toolchain to 1.94.0 via rust-toolchain.toml for deterministic
compiler output across environments. Set SOURCE_DATE_EPOCH from git
commit timestamp in CI workflows and packaging scripts to normalize
embedded timestamps.
Make packaging archives reproducible: pass --mtime=@$SOURCE_DATE_EPOCH
to tar in .deb, .ipk, and systemd tarball builds. Normalize ownership
to root:root in systemd tarballs. Pin cargo-zigbuild to 0.19.8 for
cross-compilation stability.
Add SHA-256 hash output to CI build and OpenWrt packaging workflows
for binary verification.
Add a HostMap that resolves human-readable hostnames to npubs,
enabling `gateway.fips` instead of the full `npub1...xyz.fips`.
Two sources populate the map: peer `alias` fields from the YAML
config and an operator-maintained hosts file at /etc/fips/hosts.
The DNS responder auto-reloads the hosts file on each request by
checking the file modification time, so operators can update
mappings without restarting the daemon.
- New src/upper/hosts.rs: HostMap, HostMapReloader, hostname
validation, hosts file parser with auto-reload on mtime change
- DNS resolver checks host map before falling back to direct npub
- Node uses host map for peer display names
- Default hosts file added to both .deb and tarball packaging
- 26 new tests (789 total)
Packaging directory structure:
- packaging/common/ — shared config (fips.yaml) used by all formats
- packaging/systemd/ — systemd-specific installer and service units
Systemd packaging includes:
- build-tarball.sh: builds release binaries and creates a self-contained
install tarball with stripped binaries
- fips.service: systemd unit running the daemon with security hardening
- fips-dns.service: oneshot unit configuring resolvectl to route .fips
domain queries to the FIPS DNS shim on 127.0.0.1:5354
- install.sh: deploys binaries to /usr/local/bin, installs systemd units,
creates fips group for non-root control socket access
- uninstall.sh: removes service and binaries, optional --purge for
config and identity key files
- README.install.md: installation and configuration guide
Default config enables UDP (2121), TCP inbound (8443), TUN, and DNS
resolver. Identity is ephemeral by default for privacy; operators can
uncomment persistent: true to maintain a stable npub for static peer
publishing. Ethernet transport is commented out for per-node setup.
