Add log_level field to NodeConfig (case-insensitive, default: info).
The daemon now loads config before initializing tracing so the
configured level takes effect. RUST_LOG env var still overrides if
set.
Remove hardcoded Environment=RUST_LOG=info from systemd units and
OpenWrt procd init script — these prevented config-driven log levels
from working.
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.
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
