A measurement run needs the .deb built with a non-default feature, and the
script had no way to express that: its argument loop took only --target,
--version and --no-build, and nothing forwarded a feature list or read one
from the environment. --features <list> now forwards to cargo-deb's native
-F.
The marking is the half that is easy to skip and matters more. The
auto-derived dev Version is built from the crate version, the commit date
and the sha, none of which change when a feature is enabled, so an
instrumented package and a default package of the same commit carried
byte-identical versions. Two consequences, and the second is worse than
the first: the node offers no way to tell which one it is running, and
reverting is an install of a version already present, which no-ops
silently and leaves the instrumented binary in place. That is precisely
the failure the per-commit version was introduced to prevent, reappearing
one level down. The Version now carries a +<features> marker, folded to
dots since underscores and commas are not legal there.
The marker sorts above the unmarked build, checked with dpkg
--compare-versions rather than assumed, so installing a feature build is
an upgrade and reverting is a downgrade: revert with dpkg -i, not apt
install. The ~dev ordering below a tagged release is preserved.
--features is refused together with --no-build, which would stamp the
marker onto whatever binaries happened to be sitting in target/ while
claiming the features had reached them.
Verified end to end rather than by reading: a real --features profiling
build produces a package whose fipsctl accepts the profile subcommand and
whose daemon carries the capture-file header text that only exists under
the feature gate. The release packaging path is untouched, shown by
diffing the cargo invocation the old and new scripts produce across five
argument shapes including the --version/--no-build pair the packaging
workflow uses; all five are identical.
Authored on master rather than maint, which takes bug fixes and CI or
tooling changes but not new capability, so the three copies of this
script now differ by design.
Inject git date + short SHA into the Debian Version field when
Cargo.toml's crate version ends in -dev, so apt-based upgrade
detection works without operator workarounds. Form:
<base>~dev+git<YYYYMMDD>.<sha>[.dirty]-1
e.g. 0.3.0~dev+git20260429.6def31b-1.
Each commit produces a uniquely-comparable Version, so
`apt install ./*.deb` and `ansible.builtin.apt: deb:` stop
silently no-op'ing when one dev .deb is installed on top of
another. The ~dev marker sorts pre-tagged-release so 0.3.0
supersedes any prior dev .deb. Tagged builds (Cargo.toml without
-dev) keep the clean <version>-1 form. --version override still
wins.
Note: legacy 0.3.0-dev-1 dev installs sort ABOVE the new form;
hosts upgrading from a legacy install will need `dpkg -i` once
on the next dev .deb to bypass apt's downgrade refusal.
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
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.
Debian packaging via cargo-deb:
- Add [package.metadata.deb] to Cargo.toml with assets, dependencies,
and conffiles declarations
- Maintainer scripts: postinst (create fips group, enable services,
restart on upgrade), prerm (stop/disable on remove, stop-only on
upgrade), postrm (purge config, keys, group)
- Systemd units (fips.service, fips-dns.service) with /usr/bin/ paths
for .deb installs
- tmpfiles.d entry for /run/fips/ runtime directory
- build-deb.sh wrapper script for building packages
README rewrite:
- Replace run-from-source Quick Start with Building section
- Add Installation options: Debian .deb (cargo-deb) and generic Linux
(systemd tarball)
- Add full Configuration reference with default fips.yaml
- Add Usage sections: DNS resolution, monitoring (fipsctl + fipstop),
service management, and testing
- Update project structure and features list
