A CI worker may preempt an in-flight ci-local.sh run (SIGTERM, then SIGKILL
after a grace period) to restart on a newer commit. For that kill to be safe,
the script must clean up after itself and never let a dying run collide with
its restart. It previously had no signal handling, shared the default compose
project name across runs, and tore down each suite only at the suite end.
- Derive a per-run id (honoring FIPS_CI_RUN_ID, else short-sha+random) and
namespace every docker resource to it: a fipsci_<run>_<suite> compose project
per suite and per parallel chaos child, and per-run image tags
(fips-test:<run>, fips-test-app:<run>) retagged to :latest only after both
builds succeed so :latest never points at a half-built image.
- Install a bounded, idempotent teardown trap on SIGTERM/SIGINT (+ EXIT): reap
parallel chaos children, then force-remove this run's docker resources via
the new ci-cleanup.sh, wrapped in timeout so a stuck down cannot wedge it.
- Exit 143 (SIGTERM) / 130 (SIGINT), distinct from 0 (pass) / 1 (failed), so a
preempting worker tells a cancelled run from a real failure.
- Add ci-cleanup.sh (also ci-local.sh --reap): force-removes leftover CI
resources by the com.corganlabs.fips-ci=1 label and the fipsci_ project
prefix, robust to however a prior run died.
- Label every per-suite docker resource so the label sweep reaps it after a
SIGKILL regardless of network name: direct docker run/network resources, the
sidecar compose services, and every per-suite compose network (acl-allowlist,
boringtun, firewall, nat, static, both tor suites, and the chaos generator
template). Parametrize the static/sidecar compose image refs so the per-run
tags are honored.
- Give each parallel chaos child a unique /24 from 10.30.x (a new --subnet
override on the sim CLI, assigned per-child in ci-local.sh) so parallel
children never collide on a shared docker subnet, and a chaos net can never
span a fixed-subnet suite (sidecar/static in 172.20.x). 10.30.x sits outside
docker's default-address-pool range, so an auto-assigned net cannot land on
it either; node IPs derive from the subnet, so no scenario config changes.
Operator-facing IPs in user-visible configs/docs (examples, tutorials,
packaging, sidecar templates) are now the resolvable hostnames of the
public test fleet (test-us01.fips.network, etc.) so they keep working
without baking specific addresses into examples.
Doc-comment and test fixtures in src/config/transport.rs use RFC 5737
TEST-NET-2 (198.51.100.1) so they cannot accidentally point at a real
host.
Also resyncs the openwrt-ipk fips.yaml with the common reference
(merge from master) and applies the same DNS-name swap there.
The host (217.77.8.91:443) was renamed to test-us01 some time ago
(canonical name shared with packaging/common/hosts and the docs);
the test scaffold's alias labels and narrative comments hadn't been
updated. Pure naming cleanup, no behavior change. The continued
dependency on the live external host is tracked separately.
Add TorTransport in src/transport/tor/ supporting three operating modes:
Outbound (socks5 mode):
- Non-blocking SOCKS5 connect via tokio-socks with per-destination
circuit isolation (IsolateSOCKSAuth)
- TorAddr enum for .onion and clearnet address types
- Connection pool with per-connection receive tasks, reuses TCP
stream FMP framing
- connect_async()/connection_state_sync()/promote_connection() follow
the same non-blocking polling pattern as TCP transport
Inbound (directory mode — recommended for production):
- Tor manages the onion service via HiddenServiceDir in torrc
- FIPS reads .onion address from hostname file at startup
- No control port needed — enables Tor Sandbox 1 (seccomp-bpf)
- Accept loop mirrors TCP pattern with DirectoryServiceConfig
Monitoring (control_port mode and optional in directory mode):
- Async control port client supporting TCP and Unix socket connections
via Box<dyn AsyncRead/Write> trait objects
- AUTHENTICATE with cookie or password auth
- 8 GETINFO queries: bootstrap, circuits, traffic, liveness, version,
dormant state, SOCKS listeners
- Background monitoring task polls every 10s, caches TorMonitoringInfo
in Arc<RwLock> for synchronous query access
- Bootstrap milestone logging (25/50/75/100%), stall warning (>60s),
network liveness transitions, dormant mode entry
- Directory mode optionally connects to control port when control_addr
is configured (non-fatal on failure)
Operator visibility:
- show_transports query exposes tor_mode, onion_address, tor_monitoring
(bootstrap, circuit_established, traffic, liveness, version, dormant)
- fipstop transport detail view: Tor mode, onion address, SOCKS5/control
errors, connection stats, Tor daemon status section
- fipstop table view: tor(mode) label with truncated onion address hint
Security hardening:
- Per-destination circuit isolation via IsolateSOCKSAuth
- Unix socket default for control port (/run/tor/control)
- Reference torrc with HiddenServiceDir, VanguardsLiteEnabled,
ConnectionPadding, DoS protections (PoW + intro rate limiting)
Config:
- TorConfig with socks5, control_port, and directory modes
- DirectoryServiceConfig: hostname_file, bind_addr
- control_addr, control_auth, cookie_path, connect_timeout,
max_inbound_connections
Testing:
- 69 unit + integration tests with mock SOCKS5 and control servers
- Docker tests: socks5-outbound (clearnet via Tor) and directory-mode
(HiddenServiceDir onion service)
Documentation:
- Transport layer design doc: Tor architecture, directory mode
- Configuration doc: Tor config tables and examples
