- Add 403 response to all RBAC-gated endpoints (schemathesis UndefinedStatusCode)
- Add 400 response to all endpoints accepting JSON bodies (malformed input)
- Add required 'title' field to schemathesis.toml for schemathesis 4.15+
- Add xdist_group markers to live tests with module-scoped fixtures to
prevent xdist from distributing them across workers (fixture isolation)
Extends tracing to every remaining module: all 23 API route handlers,
correlation engine, sniffer (fingerprint/p0f/syslog), prober (jarm/hassh/tcpfp),
profiler behavioral analysis, logging subsystem, engine, and mutator.
Bridges the ingester→SSE trace gap by persisting trace_id/span_id columns on
the logs table and creating OTEL span links in the SSE endpoint. Adds log-trace
correlation via _TraceContextFilter injecting otel_trace_id into Python LogRecords.
Includes development/docs/TRACING.md with full span reference (76 spans),
pipeline propagation architecture, quick start guide, and troubleshooting.
Collector now creates a span per event and injects W3C trace context
into JSON records. Ingester extracts that context and creates child
spans, connecting the full event journey: collector -> ingester ->
db.add_log + extract_bounty -> db.add_bounty.
Profiler now creates per-IP spans inside update_profiles with rich
attributes (event_count, is_traversal, bounty_count, command_count).
Traces in Jaeger now show the complete execution map from capture
through ingestion and profiling.
Gated by DECNET_DEVELOPER_TRACING env var (default off, zero overhead).
When enabled, traces flow through FastAPI routes, background workers
(collector, ingester, profiler, sniffer, prober), engine/mutator
operations, and all DB calls via TracedRepository proxy.
Includes Jaeger docker-compose for local dev and 18 unit tests.
decnet deploy spawns a standalone profiler daemon AND api.py was also starting
attacker_profile_worker as an asyncio task inside the web server. Both instances
shared the same attacker_worker_cursor key in the state table, causing a race
where one instance could skip events already claimed by the other or overwrite
the cursor mid-batch.
Default is now OFF (embedded profiler disabled). The standalone daemon started
by decnet deploy is the single authoritative instance. Set DECNET_EMBED_PROFILER=true
only when running decnet api in isolation without a full deploy.
templates/decnet_logging.py calls str(v) on all SD-PARAM values, turning a
headers dict into Python repr ('{'User-Agent': ...}') rather than JSON.
detect_tools_from_headers() called json.loads() on that string and silently
swallowed the error, returning [] for every HTTP event. Same bug prevented
the ingester from extracting User-Agent bounty fingerprints.
- templates/http/server.py: wrap headers dict in json.dumps() before passing
to syslog_line so the value is a valid JSON string in the syslog record
- behavioral.py: add ast.literal_eval fallback for existing DB rows that were
stored with the old Python repr format
- ingester.py: parse headers as JSON string in _extract_bounty so User-Agent
fingerprints are stored correctly going forward
- tests: add test_json_string_headers and test_python_repr_headers_fallback
to exercise both formats in detect_tools_from_headers
- Ingester now loads byte-offset from DB on startup (key: ingest_worker_position)
and saves it after each batch — prevents full re-read on every API restart
- On file truncation/rotation the saved offset is reset to 0
- Profiler worker now loads last_log_id from DB on startup — every restart
becomes an incremental update instead of a full cold rebuild
- Updated all affected tests to mock get_state/set_state; added new tests
covering position restore, set_state call, truncation reset, and cursor
restore/cold-start paths
Cold start fetched all logs in one bulk query then processed them in a tight
synchronous loop with no yields, blocking the asyncio event loop for seconds
on datasets of 30K+ rows. This stalled every concurrent await — including the
SSE stream generator's initial DB calls — causing the dashboard to show
INITIALIZING SENSORS indefinitely.
Changes:
- Drop _cold_start() and get_all_logs_raw(); uninitialized state now runs the
same cursor loop as incremental, starting from last_log_id=0
- Yield to the event loop after every _BATCH_SIZE rows (asyncio.sleep(0))
- Add SSE keepalive comment as first yield so the connection flushes before
any DB work begins
- Add Cache-Control/X-Accel-Buffering headers to StreamingResponse
Existing MySQL databases hit a DataError when the commands/fingerprints
JSON blobs exceed 64 KiB (TEXT limit). _BIG_TEXT emits MEDIUMTEXT only
at CREATE TABLE time; create_all() is a no-op on existing columns.
Add MySQLRepository._migrate_column_types() that queries
information_schema and issues ALTER TABLE … MODIFY COLUMN … MEDIUMTEXT
for the five affected columns (commands, fingerprints, services, deckies,
state.value) whenever they are still TEXT. Called from an overridden
initialize() after _migrate_attackers_table() and before create_all().
Add tests/test_mysql_migration.py covering: ALTER issued for TEXT columns,
no-op for already-MEDIUMTEXT, idempotency, DEFAULT clause correctness,
and initialize() call order.
- Implement MySQLRepository extending BaseRepository

Replace per-decky sniffer containers with a single host-side sniffer
that monitors all traffic on the MACVLAN interface. Runs as a background
task in the FastAPI lifespan alongside the collector, fully fault-isolated
so failures never crash the API.
- Add fleet_singleton flag to BaseService; sniffer marked as singleton
- Composer skips fleet_singleton services in compose generation
- Fleet builder excludes singletons from random service assignment
- Extract TLS fingerprinting engine from templates/sniffer/server.py
into decnet/sniffer/ package (parameterized for fleet-wide use)
- Sniffer worker maps packets to deckies via IP→name state mapping
- Original templates/sniffer/server.py preserved for future use
Extends the prober with two new active probe types alongside JARM:
- HASSHServer: SSH server fingerprinting via KEX_INIT algorithm ordering
(MD5 hash of kex;enc_s2c;mac_s2c;comp_s2c, pure stdlib)
- TCP/IP stack: OS/tool fingerprinting via SYN-ACK analysis using scapy
(TTL, window size, DF bit, MSS, TCP options ordering, SHA256 hash)
Worker probe cycle now runs three phases per IP with independent
per-type port tracking. Ingester extracts bounties for all three
fingerprint types.
New GET /attackers/{uuid}/commands?limit=&offset=&service= endpoint
serves commands with server-side pagination and optional service filter.
AttackerDetail frontend fetches commands from this endpoint with
page controls. Service badge filter now drives both the API query
and the local fingerprint filter.
API now accepts ?service=https to filter attackers by targeted service.
Service badges are clickable in both the attacker list and detail views,
navigating to a filtered view. Active filter shows as a dismissable tag.
Migrate Attacker model from IP-based to UUID-based primary key with
auto-migration for old schema. Add GET /attackers (paginated, search,
sort) and GET /attackers/{uuid} API routes. Rewrite Attackers.tsx as
a card grid with full threat info and create AttackerDetail.tsx as a
dedicated detail page with back navigation, stats, commands table,
and fingerprints.
- Modify Rfc5424Formatter to read decnet_component from LogRecord
and use it as RFC 5424 APP-NAME field (falls back to 'decnet')
- Add get_logger(component) factory in decnet/logging/__init__.py
with _ComponentFilter that injects decnet_component on each record
- Wire all five layers to their component tag:
cli -> 'cli', engine -> 'engine', api -> 'api' (api.py, ingester,
routers), mutator -> 'mutator', collector -> 'collector'
- Add structured INFO/DEBUG/WARNING/ERROR log calls throughout each
layer per the defined vocabulary; DEBUG calls are suppressed unless
DECNET_DEVELOPER=true
- Add tests/test_logging.py covering factory, filter, formatter
component-awareness, fallback behaviour, and level gating
_load_service_container_names() reads decnet-state.json and builds the
exact set of expected container names ({decky}-{service}). is_service_container()
and is_service_event() do a direct set lookup — no regex, no label
inspection, no heuristics.
Two bugs caused the log file to never be written:
1. is_service_container() used regex '^decky-\d+-\w' which only matched
the old decky-01-smtp naming style. Actual containers are named
omega-decky-smtp, relay-decky-smtp, etc. Fixed by using Docker Compose
labels instead: com.docker.compose.project=decnet + non-empty
depends_on discriminates service containers from base (sleep infinity)
containers reliably regardless of decky naming convention.
Added is_service_event() for the Docker events path.
2. The collector was only started when --api was used. Added a 'collect'
CLI subcommand (decnet collect --log-file <path>) and wired it into
deploy as an auto-started background process when --api is not in use.
Default log path: /var/log/decnet/decnet.log
Services now print RFC 5424 to stdout; Docker captures via json-file driver.
A new host-side collector (decnet.web.collector) streams docker logs from all
running decky service containers and writes RFC 5424 + parsed JSON to the host
log file. The existing ingester continues to tail the .json file unchanged.
rsyslog can consume the .log file independently — no DECNET involvement needed.
Removes: bind-mount volume injection, _LOG_NETWORK bridge, log_target config
field and --log-target CLI flag, TCP syslog forwarding from service templates.
- decnet/env.py: DECNET_JWT_SECRET and DECNET_ADMIN_PASSWORD are now
required env vars; startup raises ValueError if unset or set to a
known-bad default ("admin", "password", etc.)
- decnet/env.py: add DECNET_CORS_ORIGINS (comma-separated, defaults to
http://localhost:8080) replacing the previous allow_origins=["*"]
- decnet/web/api.py: use DECNET_CORS_ORIGINS and tighten allow_methods
and allow_headers to explicit lists
- tests/conftest.py: set required env vars at module level so test
collection works without real credentials
- tests/test_web_api.py, test_web_api_fuzz.py: use DECNET_ADMIN_PASSWORD
from env instead of hardcoded "admin"
