Before bf77ece (Fix DNS responder silent-drop on systemd-resolved
deployments, 2026-04-29) the daemon defaulted dns.bind_addr to "::"
(wildcard, accepted v4 traffic too), so the macOS pkg's resolver shim
of `nameserver 127.0.0.1` reached the daemon fine over v4 loopback.
That commit tightened the default to "::1" — IPv6 loopback only,
which on Linux/macOS does not accept v4-mapped traffic — to defuse a
mesh-interface filter / IPV6_PKTINFO bug that was silently dropping
.fips queries on systemd-resolved hosts. The Linux side was updated
in the same commit: fips-dns-setup now writes [::1]:5354 in every
backend, and the gateway's DEFAULT_DNS_UPSTREAM moved to [::1]:5354
with an inline comment about the v4/v6 mismatch.
The macOS resolver shim in packaging/macos/build-pkg.sh was missed in
that sweep. Since 2026-04-29, every macOS install has shipped
/etc/resolver/fips with `nameserver 127.0.0.1` while the daemon
listened on `::1`, so .fips hostnames don't resolve via getaddrinfo
(ping6, curl, etc.) even though `dig @::1 -p 5354 …` works.
The mismatch is easy to miss: mDNSResponder swallows the timeout,
VPN clients that hijack DNS (NetworkExtension match-domain : *) mask
it entirely, and the symptom looks like "discovery hasn't found the
peer yet". Switch the shim to nameserver ::1 to match the daemon.
The published v0.3.0 macOS installer is a structurally corrupt xar
archive: pkgutil and xar reject it even though its SHA-256 matches the
published checksum.
build-pkg.sh derived the architecture suffix in the .pkg filename from
`uname -m`. On the Apple-silicon macOS runner that always reports
arm64, so the cross-compiled x86_64 build also named its output
fips-<version>-macos-arm64.pkg. The release job downloads both build
artifacts with merge-multiple into one directory, where the two
identically named files collide and tear into a malformed result. The
x86_64 package never reaches the release at all.
Derive the package architecture from the Rust target triple, which is
authoritative for cross-compiles, instead of from the build host. Each
matrix leg now produces a distinctly named, arch-correct package, so
the two artifacts no longer collide.
Add a SHA-256 integrity chain so a corrupt or mismatched asset cannot
be published again:
- Capture the .pkg SHA-256 on the macOS runner, after the on-runner
structural verification, into a sidecar file carried in the artifact.
- Add a verify-handoff job that runs on every trigger and asserts each
downloaded .pkg still matches its macOS-runner SHA-256.
- Gate the release job on verify-handoff and repeat the check on the
exact bytes about to be published.
The build step now asserts it produced the expected arch-named package
so a regression in the naming fails loudly rather than as a silent
collision.
Relates to #102. The published v0.3.0 macOS assets still need to be
rebuilt and reuploaded separately.
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
