From 035499f25563ccee64b4183743637f3577f233e7 Mon Sep 17 00:00:00 2001 From: anti Date: Mon, 13 Apr 2026 07:39:01 -0400 Subject: [PATCH 001/241] feat: add component-aware RFC 5424 application logging system - 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 --- decnet/cli.py | 15 ++ decnet/collector/worker.py | 16 +- decnet/config.py | 3 +- decnet/engine/deployer.py | 10 ++ decnet/logging/__init__.py | 42 +++++ decnet/mutator/engine.py | 13 ++ decnet/web/api.py | 11 +- decnet/web/ingester.py | 13 +- decnet/web/router/fleet/api_deploy_deckies.py | 8 +- decnet/web/router/stream/api_stream_events.py | 4 +- tests/test_logging.py | 155 ++++++++++++++++++ 11 files changed, 270 insertions(+), 20 deletions(-) create mode 100644 tests/test_logging.py diff --git a/decnet/cli.py b/decnet/cli.py index 91415e5..b52e9b8 100644 --- a/decnet/cli.py +++ b/decnet/cli.py @@ -8,6 +8,7 @@ Usage: decnet services """ +import logging import signal from typing import Optional @@ -15,6 +16,7 @@ import typer from rich.console import Console from rich.table import Table +from decnet.logging import get_logger from decnet.env import ( DECNET_API_HOST, DECNET_API_PORT, @@ -32,6 +34,8 @@ from decnet.ini_loader import load_ini from decnet.network import detect_interface, detect_subnet, allocate_ips, get_host_ip from decnet.services.registry import all_services +log = get_logger("cli") + app = typer.Typer( name="decnet", help="Deploy a deception network of honeypot deckies on your LAN.", @@ -77,6 +81,7 @@ def api( import sys import os + log.info("API command invoked host=%s port=%d", host, port) console.print(f"[green]Starting DECNET API on {host}:{port}...[/]") _env: dict[str, str] = os.environ.copy() _env["DECNET_INGEST_LOG_FILE"] = str(log_file) @@ -115,6 +120,7 @@ def deploy( ) -> None: """Deploy deckies to the LAN.""" import os + log.info("deploy command invoked mode=%s deckies=%s dry_run=%s", mode, deckies, dry_run) if mode not in ("unihost", "swarm"): console.print("[red]--mode must be 'unihost' or 'swarm'[/]") raise typer.Exit(1) @@ -234,8 +240,13 @@ def deploy( mutate_interval=mutate_interval, ) + log.debug("deploy: config built deckies=%d interface=%s subnet=%s", len(config.deckies), config.interface, config.subnet) from decnet.engine import deploy as _deploy _deploy(config, dry_run=dry_run, no_cache=no_cache, parallel=parallel) + if dry_run: + log.info("deploy: dry-run complete, no containers started") + else: + log.info("deploy: deployment complete deckies=%d", len(config.deckies)) if mutate_interval is not None and not dry_run: import subprocess # nosec B404 @@ -290,6 +301,7 @@ def collect( """Stream Docker logs from all running decky service containers to a log file.""" import asyncio from decnet.collector import log_collector_worker + log.info("collect command invoked log_file=%s", log_file) console.print(f"[bold cyan]Collector starting[/] → {log_file}") asyncio.run(log_collector_worker(log_file)) @@ -322,6 +334,7 @@ def mutate( @app.command() def status() -> None: """Show running deckies and their status.""" + log.info("status command invoked") from decnet.engine import status as _status _status() @@ -336,8 +349,10 @@ def teardown( console.print("[red]Specify --all or --id .[/]") raise typer.Exit(1) + log.info("teardown command invoked all=%s id=%s", all_, id_) from decnet.engine import teardown as _teardown _teardown(decky_id=id_) + log.info("teardown complete all=%s id=%s", all_, id_) if all_: _kill_api() diff --git a/decnet/collector/worker.py b/decnet/collector/worker.py index 69e2c6b..d96ed4f 100644 --- a/decnet/collector/worker.py +++ b/decnet/collector/worker.py @@ -8,13 +8,14 @@ The ingester tails the .json file; rsyslog can consume the .log file independent import asyncio import json -import logging import re from datetime import datetime from pathlib import Path from typing import Any, Optional -logger = logging.getLogger("decnet.collector") +from decnet.logging import get_logger + +logger = get_logger("collector") # ─── RFC 5424 parser ────────────────────────────────────────────────────────── @@ -139,10 +140,13 @@ def _stream_container(container_id: str, log_path: Path, json_path: Path) -> Non lf.flush() parsed = parse_rfc5424(line) if parsed: + logger.debug("collector: event written decky=%s type=%s", parsed.get("decky"), parsed.get("event_type")) jf.write(json.dumps(parsed) + "\n") jf.flush() + else: + logger.debug("collector: malformed RFC5424 line snippet=%r", line[:80]) except Exception as exc: -

Now splits on LF and strips trailing CR, matching real Postfix behavior. - AUTH PLAIN without inline credentials set state to "await_plain" but no handler existed for that state, causing the next line to be dispatched as a normal command.

unify profiler to cursor-based incremental MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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)) -

These were invisible to the behavioral profiler for two reasons: 1. target_ip (prober's field name for attacker IP) was not in _IP_FIELDS in collector/worker.py or correlation/parser.py, so the profiler re-parsed raw_lines and got attacker_ip=None, never attributing prober events to the attacker profile. 2. sniffer_rollup only handled tcp_syn_fingerprint (passive sniffer) and ignored tcpfp_fingerprint (active prober).

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).

Upon `teardown`, DECNET: +1. Runs `docker compose down`. +2. Deletes the host-side macvlan interface and routes. +3. Removes the Docker network. +4. Clears the CLI state. + +--- + +## 3. Networking Internals: Passive & Active Fidelity + +### OS Fingerprinting (TCP/IP Spoofing) +DECNET tunes the networking behavior of each Decky within its own namespace. This is handled by the `os_fingerprint.py` module, which sets specific `sysctls` in the base container: +- `net.ipv4.tcp_window_scaling`: Enables/disables based on OS profile. +- `net.ipv4.tcp_timestamps`: Mimics specific OS tendencies (e.g., Windows vs. Linux). +- `net.ipv4.tcp_syncookies`: Prevents OS detection via SYN-flood response patterns. + +### The Packet Flow +1. **Ingress**: Packet hits physical NIC -> MACVLAN Bridge -> Target Decky Namespace. +2. **Telemetry**: The `Sniffer` container attaches to the same MACVLAN bridge in promiscuous mode. It uses scapy-like logic (via `decnet.sniffer`) to extract: + - **JA3/JA4**: TLS ClientHello fingerprints. + - **HASSH**: SSH Key Exchange fingerprints. + - **JARM**: (Triggered actively) TLS server fingerprints. + +--- + +## 4.

The storage schemas and API signatures defined in `decnet/web/db/models.py` are subject to radical change as the framework's analytical capabilities and distributed features expand. + +## 1. Introduction & Philosophy + +The `decnet/web/db/models.py` file represents the structural backbone of the DECNET web interface and its underlying analytical engine. It serves a dual purpose that is central to the project's architecture: + +1. **Unified Source of Truth**: By utilizing **SQLModel**, DECNET collapses the traditional barrier between Pydantic data validation and SQLAlchemy ORM mapping. This allows a single class definition to act as both a database table and an API data object, drastically reducing the "boilerplate" associated with traditional web-database pipelines. +2. **Analytical Scalability**: The models are designed to scale from small-scale local deployments using **SQLite** to large-scale, enterprise-ready environments backed by **MySQL**. This is achieved through clever usage of SQLAlchemy "Variants" and abstraction layers for large text blobs. + +--- + +## 2. The Database Layer (SQLModel Entities) + +These models define the physical tables within the DECNET infrastructure. Every class marked with `table=True` is interpreted by the repository layer to generate the corresponding DDL (Data Definition Language) for the target database. + +### 2.1 Identity & Security: The `User` Entity + +The `User` model handles dashboard access control and basic identity management. + +* `uuid`: A unique string identifier. While integers are often used for IDs, DECNET uses strings to support potential future transitions to UUIDs without schema breakage. +* `username`: The primary login handle. It is both `unique` and `indexed` for rapid authentication lookups. +* `password_hash`: Stores the Argon2 or bcrypt hash. Length constraints in various routers ensure that raw passwords never exceed 72 characters, preventing "Long Password Denial of Service" attacks on various hashing algorithms. +* `role`: A simple string-based permission field (e.g., `admin`, `viewer`). +* `must_change_password`: A boolean flag used for fresh deployments or manual administrative resets, forcing the user to rotate their credentials upon their first authenticated session. + +### 2.2 Intelligence & Attribution: `Attacker` and `AttackerBehavior` + +These two tables form the core of DECNET's "Attacker Profiling" system. They are split into two tables to maintain "Narrow vs. Wide" performance characteristics. + +#### The `Attacker` Entity (Broad Analytics) +The `Attacker` table stores the "primary" record for every unique IP discovered by the honeypot fleet. + +* `ip`: The source IP address. This is the primary key and is heavily indexed. +* `first_seen` / `last_seen`: Tracking the lifecycle of an attacker's engagement with the network. +* `event_count` / `service_count` / `decky_count`: Aggregated counters used by the stats dashboard to visualize the magnitude of an engagement. +* `services` / `deckies`: JSON-serialized lists of every service and machine reached by the attacker. Using `_BIG_TEXT` here allows these lists to grow significantly during long-term campaigns. +* `traversal_path`: A string representation (e.g., `omega → epsilon → zulu`) that helps analysts visualize lateral movement attempts recorded by the correlation engine. + +#### The `AttackerBehavior` Entity (Granular Analytics) +This "Wide" table stores behavioral signatures. It is separated from the main `Attacker` record so that high-frequency updates to timing stats or sniffer-derived packet signatures don't lock the primary attribution rows. + +* `os_guess`: Derived from the `os_fingerprint` and `sniffer` engines, providing an estimate of the attacker's operating system based on TCP/IP stack nuances. +* `tcp_fingerprint`: A JSON blob storing the raw TCP signature (Window size, MSS, Option sequence). +* `behavior_class`: A classification (e.g., `beaconing`, `interactive`, `brute_force`) derived from log inter-arrival timing (IAT). +* `timing_stats`: Stores a JSON dictionary of mean/median/stdev for event timing, used to detect automated tooling. + +### 2.3 Telemetry: `Log` and `Bounty` + +These tables store the "raw" data generated by the honeypots. + +* **`Log` Table**: The primary event sink. Every line from the collector ends up here. + * `event_type`: The MSGID from the RFC 5424 header (e.g., `connect`, `exploit`). + * `raw_line`: The full, un-parsed syslog string for forensic verification. + * `fields`: A JSON blob containing the structured data (SD-ELEMENTS) extracted during normalization. +* **`Bounty` Table**: Specifically for high-value events. When a service detects "Gold" (like a plain-text password or a known PoC payload), it is mirrored here for rapid analyst review. + +### 2.4 System State: The `State` Entity + +The `State` table acts as the orchestrator's brain. It stores the `decnet-state.json` content within the database when the system is integrated with the web layer. + +* `key`: The configuration key (e.g., `global_config`, `active_deployment`). +* `value`: A `MEDIUMTEXT` JSON blob. This is potentially its largest field, storing the entire resolved configuration of every running Decky. + +--- + +## 3. The API Layer (Pydantic DTOs) + +These models define how data moves across the wire between the FastAPI backend and the frontend. + +### 3.1 Authentication Pipeline +* `LoginRequest`: Validates incoming credentials before passing them to the security middleware. +* `Token`: The standard OAuth2 bearer token response, enriched with the `must_change_password` hint. +* `ChangePasswordRequest`: Ensures the old password is provided and the new one meets the project's security constraints. + +### 3.2 Reporting & Pagination +DECNET uses a standardized "Envelope" pattern for broad analytical responses (`LogsResponse`, `AttackersResponse`, `BountyResponse`). + +* `total`: The total count of matching records in the database (ignoring filters). +* `limit` / `offset`: The specific slice of data returned, supporting "Infinite Scroll" or traditional pagination in the UI. +* `data`: A list of dictionaries. By using `dict[str, Any]` here, the API remains flexible with SQLModel's dynamic attribute loading. + +### 3.3 System Administration +* **`DeployIniRequest`**: The most critical input model. It takes `ini_content` as a validated string. By using the `IniContent` annotated type, the API rejects malformed deployments before they ever touch the fleet builder. +* **`MutateIntervalRequest`**: Uses a strict REGEX pattern (`^[1-9]\d*[mdMyY]$`) to ensure intervals like `30m` (30 minutes) or `2d` (2 days) are valid before being applied to the orchestrator. + +--- + +## 4. Technical Foundations + +### 4.1 Cross-DB Compatibility Logic +The project uses a custom variant system to handle the discrepancies between SQLite (which has simplified typing) and MySQL (which has strict size constraints). + +```python +_BIG_TEXT = Text().with_variant(MEDIUMTEXT(), "mysql") +``` + +This abstraction ensures that fields like `Attacker.services` (which can grow to thousands of items) are stored as `MEDIUMTEXT` (16 MiB) on MySQL, whereas standard SQLAlchemy `Text` (often 64 KiB on MySQL) would silently truncate the data, leading to analytical loss. + +### 4.2 High-Fidelity Normalization +Data arriving from distributed honeypots is often "dirty." The models include custom pre-validators like `_normalize_null`. + +* **Null Coalescing**: Services often emit logging values as `"null"` or `"undefined"` strings. The `NullableString` type automatically converts these "noise" strings into actual Python `None` types during ingestion. +* **Timestamp Integrity**: `NullableDatetime` ensures that various ISO formats or epoch timestamps provided by different service containers are normalized into standard UTC datetime objects. + +--- + +## 5. Integration Case Studies (Deep Analysis) + +To understand how these models function, we must examine their lifecycle across the web stack. + +### 5.1 The Repository Layer (`decnet/web/db/sqlmodel_repo.py`) +The repository is the primary consumer of the "Entities." It utilizes the metadata generated by SQLModel to: +1. **Generate DDL**: On startup, the repository calls `SQLModel.metadata.create_all()`. This takes every `table=True` class and translates it into `CREATE TABLE` statements tailored to the active engine (SQLite or MySQL). +2. **Translate DTOs**: When the repository fetches an `Attacker` from the DB, SQLModel automatically populates the Pydantic-style attributes, allowing the repository to return objects that are immediately serializeable by the routers. + +### 5.2 The Dashboard Routers +Specific endpoints rely on these models for boundary safety: + +* **`api_deploy_deckies.py`**: Uses `DeployIniRequest`. This ensures that even if a user tries to POST a massive binary file instead of an INI, the Pydantic layer (powered by `decnet.models.validate_ini_string`) will intercept and reject the request with a `422 Unprocessable Entity` error before it reaches the orchestrator. +* **`api_get_stats.py`**: Uses `StatsResponse`. This model serves as a "rollup" that aggregates data from the `Log`, `Attacker`, and `State` tables into a single unified JSON object for the dashboard's "At a Glance" view. +* **`api_get_health.py`**: Uses `HealthResponse`. This model provides a nested view of the system, where each sub-component (Engine, Collector, DB) is represented as a `ComponentHealth` object, allowing the UI to show granular "Success" or "Failure" states. + +--- + +## 6. Futureproofing & Guidelines + +As the project grows, the following habits must be maintained: + +1. **Keep the Row Narrow**: Always separate behavioral data that updates frequently into auxiliary tables like `AttackerBehavior`. +2. **Use Variants**: Never use standard `String` or `Text` for JSON blobs; always use `_BIG_TEXT` to respect MySQL's storage limitations. +3. **Validate at the Boundary**: Ensure every new API request model uses Pydantic's strict typing to prevent malicious payloads from reaching the database layer.

Fri, 17 Apr 2026 22:20:05 -0400 Subject: [PATCH 128/241] feat(ssh): capture attacker-dropped files with session attribution inotifywait watches writable paths in the SSH decky and mirrors any file close_write/moved_to into a per-decky host-mounted quarantine dir. Each artifact carries a .meta.json with attacker attribution resolved by walking the writer PID's PPid chain to the sshd session leader, then cross-referencing ss and utmp for source IP/user/login time. Also emits an RFC 5424 syslog line per capture for SIEM correlation. --- decnet/services/ssh.py | 5 + templates/ssh/Dockerfile | 16 ++- templates/ssh/capture.sh | 228 ++++++++++++++++++++++++++++++++++++ templates/ssh/entrypoint.sh | 5 + tests/test_ssh.py | 140 ++++++++++++++++++++++ 5 files changed, 390 insertions(+), 4 deletions(-) create mode 100755 templates/ssh/capture.sh diff --git a/decnet/services/ssh.py b/decnet/services/ssh.py index db2ce54..e358931 100644 --- a/decnet/services/ssh.py +++ b/decnet/services/ssh.py @@ -36,12 +36,17 @@ class SSHService(BaseService): if "hostname" in cfg: env["SSH_HOSTNAME"] = cfg["hostname"] + # File-catcher quarantine: bind-mount a per-decky host dir so attacker + # drops (scp/sftp/wget) are mirrored out-of-band for forensic analysis. + # The container path is internal-only; attackers never see this mount. + quarantine_host = f"/var/lib/decnet/artifacts/{decky_name}/ssh" return { "build": {"context": str(TEMPLATES_DIR)}, "container_name": f"{decky_name}-ssh", "restart": "unless-stopped", "cap_add": ["NET_BIND_SERVICE"], "environment": env, + "volumes": [f"{quarantine_host}:/var/decnet/captured:rw"], } def dockerfile_context(self) -> Path: diff --git a/templates/ssh/Dockerfile b/templates/ssh/Dockerfile index 230d429..441fb66 100644 --- a/templates/ssh/Dockerfile +++ b/templates/ssh/Dockerfile @@ -13,15 +13,22 @@ RUN apt-get update && apt-get install -y --no-install-recommends \ procps \ htop \ git \ + inotify-tools \ + psmisc \ + iproute2 \ + jq \ && rm -rf /var/lib/apt/lists/* -RUN mkdir -p /var/run/sshd /root/.ssh /var/log/decnet +RUN mkdir -p /var/run/sshd /root/.ssh /var/log/decnet /var/decnet/captured \ + && chmod 700 /var/decnet /var/decnet/captured -# sshd_config: allow root + password auth +# sshd_config: allow root + password auth; VERBOSE so session lines carry +# client IP + session PID (needed for file-capture attribution).

Drop the stale per-template copies; setuptools find was picking them up anyway. Swap useradd/USER/chown "decnet" for "logrelay" so no obvious token appears in the rendered container image. Apply the same cloaking pattern to the telnet template that SSH got: syslog pipe moves to /run/systemd/journal/syslog-relay and the relay is cat'd via exec -a "systemd-journal-fwd". rsyslog.d conf rename 99-decnet.conf → 50-journal-forward.conf. SSH capture script: /var/decnet/captured → /var/lib/systemd/coredump (real systemd path), logger tag decnet-capture → systemd-journal. Compose volume updated to match the new in-container quarantine path. SD element ID shifts decnet@55555 → relay@55555; synced across collector, parser, sniffer, prober, formatter, tests, and docs so the host-side pipeline still matches what containers emit. ---

The bash running journal-relay showed its argv[1] (the script path) in /proc/PID/cmdline, producing a line like 'journal-relay /usr/libexec/udev/journal-relay' Apply argv_zap.so to that bash too. 2. argv_zap previously hardcoded PR_SET_NAME to 'kmsg-watch', which was wrong for any caller other than inotifywait. The comm name now comes from ARGV_ZAP_COMM so each caller can pick its own (kmsg-watch for inotifywait, journal-relay for the watcher bash). 3. The capture.sh header started with 'SSH honeypot file-catcher' — fatal if an attacker runs 'cat' on it.

Pack all three into /entrypoint.sh as XOR+gzip+base64 blobs at build time (_build_stealth.py), then decode in-memory at container start and exec the capture loop from a bash -c string. No .py files under /opt, no journal-relay file under /usr/libexec/udev, no argv_zap name anywhere. The LD_PRELOAD shim is installed as /usr/lib/x86_64-linux-gnu/libudev-shared.so.1 — sits next to the real libudev.so.1 and blends into the multiarch layout. A 1-byte random XOR key is chosen at image build so a bare 'base64 -d | gunzip' probe on the visible entrypoint returns binary noise instead of readable Python.

with serverAuth + clientAuth EKU so the same identity backs the agent's HTTPS endpoint AND the syslog-over-TLS upstream. - write_worker_bundle() / load_worker_bundle() — persist with 0600 on private keys. - fingerprint() — SHA-256 DER hex for master-side pinning. tests/swarm/test_pki.py covers: - CA idempotency on disk. - Signed chain validates against CA subject. - SAN population (DNS + IP). - Bundle roundtrip with 0600 key perms. - End-to-end mTLS handshake between two CA-issued peers. - Cross-CA client rejection (handshake fails). --- decnet/swarm/__init__.py | 7 + decnet/swarm/pki.py |

Offset is persisted in a tiny local SQLite so master outages never cause loss or duplication — reconnect resumes from the exact byte where the previous session left off. Impostor workers (cert not signed by DECNET CA) are rejected at TLS handshake. Master-side log_listener terminates mTLS on 0.0.0.0:6514, validates the client cert, extracts the peer CN as authoritative worker provenance, and appends each frame to the master's ingest log files. Attacker- controlled syslog HOSTNAME field is ignored — the CA-controlled CN is the only source of provenance. 7 tests added covering framing codec, offset persistence across reopens, end-to-end mTLS delivery, crash-resilience (offset survives restart, no duplicate shipping), and impostor-CA rejection.

failure modes the happy-path tests miss: - log rotation (copytruncate): st_size shrinks under the forwarder, it resets offset=0 and reships the new contents instead of getting wedged past EOF; - listener restart: forwarder retries, resumes from the persisted offset, and the previously-acked lines are NOT duplicated on the master; - listener tolerates a well-authenticated client that sends a partial octet-count frame and drops — the server must stay up and accept follow-on connections; - peer_cn / fingerprint_from_ssl degrade to 'unknown' / None when no peer cert is available (defensive path that otherwise rarely fires). --- tests/swarm/test_forwarder_resilience.py | 256 +++++++++++++++++++++++ 1 file changed, 256 insertions(+) create mode 100644

The worker's deployer then calls get_host_ip(config.interface), hits 'ip addr show wlp6s0' on a VM whose NIC is enp0s3, and 500s. Fix: agent.executor._relocalize() runs on every swarm-mode deploy. Re-detects the worker's interface/subnet/gateway/host_ip locally and swaps them into the config before calling deployer.deploy(). When the worker's subnet doesn't match the master's, decky IPs are re-allocated from the worker's subnet via allocate_ips() so they're reachable. Unihost-mode configs are left untouched — they're already built against the local box and second-guessing them would be wrong. Validated against anti@192.168.1.13: master dispatched interface=wlp6s0, agent logged 'relocalized interface=enp0s3', deployer ran successfully, dry-run returned ok=deployed. 4 new tests cover both branches (matching-subnet preserves decky IPs; mismatch re-allocates), the end-to-end executor.deploy() path, and the unihost short-circuit. --- decnet/agent/executor.py | 54 +++++++++++- tests/swarm/test_agent_relocalize.py | 118 +++++++++++++++++++++++++++ 2 files changed, 171 insertions(+), 1 deletion(-) create mode 100644 tests/swarm/test_agent_relocalize.py diff --git a/decnet/agent/executor.py b/decnet/agent/executor.py index 9e4ba5f..3c1030f 100644 --- a/decnet/agent/executor.py +++ b/decnet/agent/executor.py @@ -9,22 +9,74 @@ blocking) so the FastAPI event loop stays responsive. from __future__ import annotations import asyncio +from ipaddress import IPv4Network from typing import Any from decnet.engine import deployer as _deployer from decnet.config import DecnetConfig, load_state, clear_state from decnet.logging import get_logger +from decnet.network import ( + allocate_ips, + detect_interface, + detect_subnet, + get_host_ip, +) log = get_logger("agent.executor") +def _relocalize(config: DecnetConfig) -> DecnetConfig: + """Rewrite a master-built config to the worker's local network reality. + + The master populates ``interface``/``subnet``/``gateway`` from its own + box before dispatching, which blows up the deployer on any worker whose + NIC name differs (common in heterogeneous fleets — master on ``wlp6s0``, + worker on ``enp0s3``).

All run as User=decnet with NoNewPrivileges, ProtectSystem, PrivateTmp, LockPersonality; AmbientCapabilities=CAP_NET_ADMIN CAP_NET_RAW only on the agent (MACVLAN/scapy). Existing api/web units migrated to /opt/decnet layout and the same hardening stanza. Make the updater's _spawn_agent systemd-aware: under systemd (detected via INVOCATION_ID + systemctl on PATH), `systemctl restart decnet-agent.service` replaces the Popen path so the new agent inherits the unit's ambient caps instead of the updater's empty set. _stop_agent becomes a no-op in that mode to avoid racing systemctl's own stop phase.

Reuses the existing UpdaterClient + tar_working_tree + the per-host asyncio.gather pattern from api_deploy_swarm.py; tarball is built exactly once per /push request and fanned out to every selected worker. /hosts filters out decommissioned hosts and agent-only enrollments (no updater bundle = not a target). Connection drops during /update-self are treated as success — the updater re-execs itself mid-response, so httpx always raises. Pydantic models live in decnet/web/db/models.py (single source of truth). 24 tests cover happy paths, rollback, transport failures, include_self ordering (skip on rolled-back agents), validation, and RBAC gating. --- decnet/web/db/models.py | 69 +++++++ decnet/web/router/__init__.py | 4 + decnet/web/router/swarm_updates/__init__.py | 23 +++ .../swarm_updates/api_list_host_releases.py | 82 ++++++++ .../router/swarm_updates/api_push_update.py | 152 +++++++++++++++ .../swarm_updates/api_push_update_self.py | 92 +++++++++ .../router/swarm_updates/api_rollback_host.py | 70 +++++++ tests/api/swarm_updates/__init__.py | 0 tests/api/swarm_updates/conftest.py | 151 +++++++++++++++ .../swarm_updates/test_list_host_releases.py | 69 +++++++ tests/api/swarm_updates/test_push_update.py | 176 ++++++++++++++++++ .../swarm_updates/test_push_update_self.py | 67 +++++++ tests/api/swarm_updates/test_rollback_host.py | 86 +++++++++ 13 files changed, 1041 insertions(+) create mode 100644 decnet/web/router/swarm_updates/__init__.py create mode 100644 decnet/web/router/swarm_updates/api_list_host_releases.py create mode 100644 decnet/web/router/swarm_updates/api_push_update.py create mode 100644 decnet/web/router/swarm_updates/api_push_update_self.py create mode 100644 decnet/web/router/swarm_updates/api_rollback_host.py create mode 100644 tests/api/swarm_updates/__init__.py create mode 100644 tests/api/swarm_updates/conftest.py create mode 100644 tests/api/swarm_updates/test_list_host_releases.py create mode 100644 tests/api/swarm_updates/test_push_update.py create mode 100644 tests/api/swarm_updates/test_push_update_self.py create mode 100644 tests/api/swarm_updates/test_rollback_host.py diff --git a/decnet/web/db/models.py b/decnet/web/db/models.py index 4173f9f..9c9dca4 100644 --- a/decnet/web/db/models.py +++ b/decnet/web/db/models.py @@ -373,3 +373,72 @@ class SwarmHostHealth(BaseModel): class SwarmCheckResponse(BaseModel): results: list[SwarmHostHealth] + + +# --- Remote Updates (master → worker /updater) DTOs --- +# Powers the dashboard's Remote Updates page.

charset=UTF-8 Content-Transfer-Encoding: 8bit Mirrors the agent→forwarder pattern: `decnet swarmctl` now fires the syslog-TLS listener as a detached Popen sibling so a single master invocation brings the full receive pipeline online. --no-listener opts out for operators who want to run the listener on a different host (or under their own systemd unit). Listener bind host / port come from DECNET_LISTENER_HOST and DECNET_SWARM_SYSLOG_PORT — both seedable from /etc/decnet/decnet.ini. PID at $(pid_dir)/listener.pid so operators can kill/restart manually. decnet.ini.example ships alongside env.config.example as the documented surface for the new role-scoped config. Mode, forwarder targets, listener bind, and master ports all live there — no more memorizing flag trees. Extends tests/test_auto_spawn.py with two swarmctl cases: listener is spawned with the expected argv + PID file, and --no-listener suppresses. --- decnet.ini.example | 63 ++++++++++++++++++++++++++++++++++++ decnet/cli.py | 29 ++++++++++++++++- tests/test_auto_spawn.py | 69 ++++++++++++++++++++++++++++++++++++++++ 3 files changed, 160 insertions(+), 1 deletion(-) create mode 100644 decnet.ini.example diff --git a/decnet.ini.example b/decnet.ini.example new file mode 100644 index 0000000..82071d7 --- /dev/null +++ b/decnet.ini.example @@ -0,0 +1,63 @@ +; /etc/decnet/decnet.ini — DECNET host configuration +; +; Copy to /etc/decnet/decnet.ini and edit.
