- 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.
Rekey dual-initiation race (FMP + FSP):
When both sides' rekey timers fire simultaneously on high-latency links
(Tor ~700ms RTT), both msg1s cross in flight before dampening can
suppress the second initiation. Each node acts as both initiator and
responder, with set_pending_session() from the responder path destroying
the initiator's in-progress state. Each side ends up with a
pending_new_session from a different Noise handshake, causing AEAD
verification failure after cutover and link death. Fix: deterministic
tie-breaker in both FMP msg1 handler and FSP SessionSetup handler
(smaller NodeAddr wins as initiator). Also guard against pending session
overwrite from retransmitted msg1s.
Parent selection SRTT gate:
Peers without MMP RTT data are excluded from parent candidacy via
has_srtt() filter, preventing freshly reconnected peers from appearing
artificially attractive. First-RTT triggers immediate parent re-eval.
The gate in evaluate_parent() skips unmeasured candidates when any peer
has cost data, but falls back to default cost 1.0 during cold start
when no peer has MMP data yet.
Auto-reconnect on all peer removal paths:
The excessive-decryption-failure and peer-restart epoch-mismatch removal
paths were missing schedule_reconnect() calls, causing auto-connect peers
to be permanently abandoned after those events.
Control socket accessibility:
Socket and parent directory chowned to root:fips with mode 0770/0750 so
group members can use fipsctl/fipstop without root.
Log level changes:
Default RUST_LOG changed to debug in systemd service files. "Unknown
session index" log reduced from debug to trace.
Add resolve_socket_addr() with IP fast path and tokio::net::lookup_host()
fallback for DNS hostnames. Peer addresses can now use hostnames like
"peer1.example.com:2121" alongside IP addresses.
UDP transport adds a per-transport DNS cache (60s TTL) to avoid
per-packet resolution. TCP resolves at connect time (one-shot).
Update design docs, config examples, and changelog to reflect hostname
support in transport addressing.
The fips-dns.service unit had three issues:
1. Wants=systemd-resolved.service caused systemd to start systemd-resolved
on systems that weren't using it, breaking existing DNS by rewriting
/etc/resolv.conf to the stub resolver at 127.0.0.53.
2. The ExecStart busy-wait loop for fips0 had no timeout, hanging forever
if fips.service failed to create the TUN device.
3. Installers unconditionally enabled fips-dns.service regardless of whether
systemd-resolved was present.
Fix by replacing Wants= with ConditionPathExists=/run/systemd/resolve (skips
cleanly if resolved isn't running), adding Requires=fips.service (won't start
without the daemon), bounding the fips0 wait loop to 30 seconds, and making
the installers conditional on systemd-resolved being active.
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.
