From cbd78f0f00503b99fd0671b8087aaa4613bf80d0 Mon Sep 17 00:00:00 2001 From: John Bargman Date: Mon, 20 Jul 2026 11:16:54 +0000 Subject: [PATCH 01/95] =?UTF-8?q?feat(planar-topology):=20Phases=200-5=20?= =?UTF-8?q?=E2=80=94=20planar=20JSON=20topology=20+=20dormant=20registry?= =?UTF-8?q?=20pipeline?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Planar topology implementation per /speed-storage/opencode/docs/planar-topology-PLAN.md. All work is dormant — gated behind `topology.useNewPipeline = false` (NixOS option). Production path (topology/*.nix → core-router.nix) unchanged; byte-identical goldens preserved for 16/17 machines (cortex-alpha regressed by genNginx signature bug, tracked for Phase 5 gate fix). Phase 0 (data cleanup): - 36 topology/.json files created from existing .nix data, hub-shape schema (14 fields: hostname, trust, hub_of, coordinate, public_key_file, etc.) - topology/_template.json schema template - topology/shared.json minimal cross-host data - consolidate _-prefixed fields into _legacy object per file - trust = max(coordinate[*].trust), default 3 (managed VPN) - public_key_file convention: secrets/public_keys/wireguard/wg__pub - LAN plane names standardized to cortex-alpha.lan + 10.88.128.0/24 Phase 1 (registry as dormant code): - lib/topology/mkRegistry.nix (398 lines): reads all topology/*.json, builds hosts/shared/planes maps, runs 10+ validators, reports 8 expected Phase 0 data errors (building-b lacks hub_of, 6 peer_id collisions, invalid CIDR) - flake.nix: topology-registry binding (line 47) + inherit (line 254) - tests/topology/mkRegistry.nix: 13 unit tests (all pass) Phase 2 (registry wired into topology pipeline): - modules/core-router-topology.nix: topology.useNewPipeline NixOS option (default false); reads registry.hosts vs. legacy topology/.nix - flake.nix: checks.x86_64-linux.network-config generalized to all 17 machines via lib.genAttrs over self.nixosConfigurations Phase 3 (schema additions): - lib/topology/mkHorizons.nix (290 lines): per-machine transformer, reads registry, validates requires_routes (BFS R1-R4), icmp_override inheritance - tests/topology/mkHorizons.nix: 11 unit tests (all pass) - documentation/topology-schema.md (359 lines): full 14-field schema docs Phase 4 (dead code with unit tests): - lib/topology/genNginx.nix (45 lines): per-(vhost, plane) stanzas - lib/topology/genDnsmasqHorizons.nix (62 lines): per-subnet listen-address - lib/topology/genNftablesMatrix.nix (203 lines): per-interface ICMP, WAN masquerade via non-RFC1918/non-CGNAT detection - tests/topology/{genNginx,genDnsmasqHorizons,genNftablesMatrix}.nix: pass - lib/topology/default.nix: mkHorizons export Phase 5 (wire-in opt-in): - lib/topology/mkNginxSettings.nix: vhostPlanes conditional branch - lib/topology/genDns.nix: dns.planes conditional branch - both dormant — no machine has new schema fields yet Known issue (carried from Phase 4): genNginx.nix signature changed from (settings, hostname) to (horizon) in Phase 4 stub; core-router-topology.nix:50 still calls with 2 args. cortex-alpha evaluation breaks when module loads. To be fixed before Phase 5 gate approval. No secrets committed — topology JSON contains only paths to public key files, never the keys themselves. --- documentation/topology-schema.md | 556 ++++++++++++++++---------- flake.nix | 49 ++- lib/topology/default.nix | 3 + lib/topology/genDns.nix | 67 +++- lib/topology/genDnsmasqHorizons.nix | 62 +++ lib/topology/genNftablesMatrix.nix | 203 ++++++++++ lib/topology/genNginx.nix | 123 ++---- lib/topology/mkHorizons.nix | 290 ++++++++++++++ lib/topology/mkNginxSettings.nix | 48 ++- lib/topology/mkRegistry.nix | 398 ++++++++++++++++++ modules/core-router-topology.nix | 30 +- tests/topology/genDnsmasqHorizons.nix | 56 +++ tests/topology/genNftablesMatrix.nix | 68 ++++ tests/topology/genNginx.nix | 61 +++ tests/topology/mkHorizons.nix | 221 ++++++++++ tests/topology/mkRegistry.nix | 209 ++++++++++ topology/LINDA.json | 32 ++ topology/_template.json | 35 ++ topology/alpha-one.json | 32 ++ topology/alpha-three.json | 23 ++ topology/alpha-two.json | 23 ++ topology/ap.json | 24 ++ topology/arm-builder.json | 23 ++ topology/building-b.json | 35 ++ topology/cluster-box.json | 23 ++ topology/cortex-alpha.json | 61 +++ topology/display-0.json | 23 ++ topology/display-1.json | 23 ++ topology/display-2.json | 23 ++ topology/dlyon.json | 23 ++ topology/gaming-host-1.json | 23 ++ topology/grimterm.json | 23 ++ topology/linda-lan.json | 34 ++ topology/linda-wm.json | 27 ++ topology/lindacore-87.json | 27 ++ topology/lindacore-88.json | 37 ++ topology/lindacore-89.json | 27 ++ topology/local-nas.json | 21 + topology/michel-248.json | 24 ++ topology/michel-wifi-247.json | 24 ++ topology/office-1.json | 23 ++ topology/office-2.json | 23 ++ topology/print-controller-wg.json | 34 ++ topology/print-controller.json | 32 ++ topology/remote-builder.json | 23 ++ topology/remote-worker.json | 23 ++ topology/shared.json | 9 + topology/storage-array.json | 23 ++ topology/terminal-nx-01-1.json | 34 ++ topology/terminal-nx-01-2.json | 34 ++ topology/terminal-nx-01.json | 32 ++ topology/terminal-zero-1.json | 34 ++ topology/terminal-zero-2.json | 34 ++ topology/terminal-zero.json | 32 ++ 54 files changed, 3153 insertions(+), 351 deletions(-) create mode 100644 lib/topology/genDnsmasqHorizons.nix create mode 100644 lib/topology/genNftablesMatrix.nix create mode 100644 lib/topology/mkHorizons.nix create mode 100644 lib/topology/mkRegistry.nix create mode 100644 tests/topology/genDnsmasqHorizons.nix create mode 100644 tests/topology/genNftablesMatrix.nix create mode 100644 tests/topology/genNginx.nix create mode 100644 tests/topology/mkHorizons.nix create mode 100644 tests/topology/mkRegistry.nix create mode 100644 topology/LINDA.json create mode 100644 topology/_template.json create mode 100644 topology/alpha-one.json create mode 100644 topology/alpha-three.json create mode 100644 topology/alpha-two.json create mode 100644 topology/ap.json create mode 100644 topology/arm-builder.json create mode 100644 topology/building-b.json create mode 100644 topology/cluster-box.json create mode 100644 topology/cortex-alpha.json create mode 100644 topology/display-0.json create mode 100644 topology/display-1.json create mode 100644 topology/display-2.json create mode 100644 topology/dlyon.json create mode 100644 topology/gaming-host-1.json create mode 100644 topology/grimterm.json create mode 100644 topology/linda-lan.json create mode 100644 topology/linda-wm.json create mode 100644 topology/lindacore-87.json create mode 100644 topology/lindacore-88.json create mode 100644 topology/lindacore-89.json create mode 100644 topology/local-nas.json create mode 100644 topology/michel-248.json create mode 100644 topology/michel-wifi-247.json create mode 100644 topology/office-1.json create mode 100644 topology/office-2.json create mode 100644 topology/print-controller-wg.json create mode 100644 topology/print-controller.json create mode 100644 topology/remote-builder.json create mode 100644 topology/remote-worker.json create mode 100644 topology/shared.json create mode 100644 topology/storage-array.json create mode 100644 topology/terminal-nx-01-1.json create mode 100644 topology/terminal-nx-01-2.json create mode 100644 topology/terminal-nx-01.json create mode 100644 topology/terminal-zero-1.json create mode 100644 topology/terminal-zero-2.json create mode 100644 topology/terminal-zero.json diff --git a/documentation/topology-schema.md b/documentation/topology-schema.md index c8b8a880..0a59f598 100644 --- a/documentation/topology-schema.md +++ b/documentation/topology-schema.md @@ -1,219 +1,359 @@ -# Topology Schema Documentation +# Topology Schema (Planar) + +> **Status:** This document is the canonical description of the new planar topology schema +> (post-Phase 0).

Filename and `hostname` field MUST match — this is enforced by the registry. +- `topology/shared.json` holds cross-host data (WireGuard peer metadata, DHCP ranges, etc.). +- `topology/_template.json` is the machine-readable template for new hosts — operators copy + this file, rename it, and fill in the fields. +- `lib/topology/mkRegistry.nix` reads every `topology/*.json` (excluding `shared.json` and + `_template.json`) via `builtins.readDir` + `builtins.readFile` + `builtins.fromJSON` and + produces a validated registry attrsect: `{ hosts, shared, planes, errors, warnings }`. +- `lib/topology/mkHorizons.nix` is the per-machine horizon transformer: it consumes the + registry and a hostname, then produces the host's resolved settings (coordinate, hub_of, + effective ICMP, applicable routes, vhostPlanes, errors, warnings). + +## Schema Fields (13 per-host fields) + +### `hostname` (required) + +- **Type:** String +- **Description:** The canonical hostname of the machine. MUST match the filename stem + (e.g., a file named `topology/cortex-alpha.json` MUST have `"hostname": "cortex-alpha"`). + Mismatch is a build error enforced by `lib/topology/mkRegistry.nix`. +- **Example:** + ```json + "hostname": "cortex-alpha" + ``` + +### `role` (required) + +- **Type:** String (enum) +- **Description:** The machine's network role. The registry uses this for categorization; + specific values are: + - `"leaf"` — A pure leaf node with no `hub_of` entries. + - `"hub"` — Defines one or more planes (has non-empty `hub_of`). + - `"sub-hub"` — A hub that also has a parent coordinate with a `parent` reference. + - `"workstation"` — User workstation. + - `"server"` — Server (non-hub). + - `"bastion"` — Bastion/jump host. + - `"ap"` — Access point. + - `"iot"` — IoT device. + - `"client"` — Generic client device. +- **Example:** + ```json + "role": "hub" + ``` + +### `trust` (optional, default `3`) + +- **Type:** Integer (0–6) +- **Description:** The host's overall trust level. This is a summary value; per-coordinate + trust is specified in each `coordinate` entry. Trust is metadata for operator reasoning + and the 3D render — it is NOT route-level policy (routes are explicit whitelist entries). + See [Trust levels](#trust-levels) below for the full scale. +- **Example:** + ```json + "trust": 5 + ``` + +### `coordinate` (required, array) + +- **Type:** Array of objects +- **Description:** The host's position on every network plane it participates in. Each + coordinate entry is one tuple `(plane_name, subnet, peer_id, trust, interface)`. + A coordinate is NOT just a subnet — the subnet is the plane, the peer_id is the host's + position on that plane, and together `(subnet, peer_id, trust)` form a point in 3D space. +- **Required fields per entry:** + - `plane_name` (string) — Opaque identifier for the plane (e.g., `"cortex-alpha.lan"`). + - `subnet` (string, CIDR) — The subnet in CIDR notation (e.g., `"10.88.128.0/24"`). + - `peer_id` (integer) — The host's position on the subnet (the /32 host octet, or host + portion of a longer prefix). Unique per `(plane_name, subnet)` pair across the registry. + - `trust` (integer, 0–6) — Per-coordinate trust value for this plane. + - `interface` (string) — The local interface name (e.g., `"enp3s0"`, `"wireg0"`). +- **Optional fields:** + - `parent` (object or null) — For sub-hubs, a reference to the parent hub: + `{ "host": "", "subnet": "" }`. +- **Example:** + ```json + "coordinate": [ + { "plane_name": "cortex-alpha.lan", "subnet": "10.88.128.0/24", "peer_id": 1, "trust": 1, "interface": "enp3s0" }, + { "plane_name": "wg", "subnet": "10.88.127.0/24", "peer_id": 1, "trust": 3, "interface": "wireg0" }, + { "plane_name": "tailscale-platonic", "subnet": "100.64.0.0/10", "peer_id": 1, "trust": 2, "interface": "tailscale0" } + ] + ``` + +### `hub_of` (optional, default `[]`) + +- **Type:** Array of objects +- **Description:** The planes this host anchors. Each entry declares that this host is the + hub of the given `(plane_name, subnet)` pair. A host with `hub_of: []` is a pure leaf + (valid edge case). Exactly one host per `(plane_name, subnet)` pair may declare `hub_of`. +- **Required fields per entry:** + - `plane_name` (string) + - `subnet` (string, CIDR) +- **Example:** + ```json + "hub_of": [ + { "plane_name": "cortex-alpha.lan", "subnet": "10.88.128.0/24" }, + { "plane_name": "wg", "subnet": "10.88.127.0/24" } + ] + ``` + +### `icmp_defaults` (optional, default `{ "pmtud": true, "ping": false }`) + +- **Type:** Object +- **Description:** Default ICMP policy for all interfaces on this host. The two recognized + keys are `pmtud` (allow ICMP type 3 destination-unreachable for PMTUD) and `ping` (allow + ICMP echo-request/echo-reply). Per-interface overrides in `icmp_override` take precedence. +- **Example:** + ```json + "icmp_defaults": { + "pmtud": true, + "ping": false + } + ``` + +### `icmp_override` (optional, default `{}`) + +- **Type:** Object keyed by interface name +- **Description:** Per-interface ICMP policy overrides. Each key is an interface name; each + value is an object with `pmtud` and/or `ping` booleans. Every key MUST match an interface + in the host's `coordinate[*].interface` (enforced by the registry as a warning). + Resolution order: `icmp_override[iface] ?? icmp_defaults ?? { pmtud: true, ping: false }`. +- **Example:** + ```json + "icmp_override": { + "enp3s0": { "ping": true }, + "tailscale0": { "ping": true } + } + ``` + +### `routes` (optional, default `[]`) + +- **Type:** Array of objects +- **Description:** Explicit whitelist of allowed traffic between subnets. The default is + DROP — every route is an explicit allow. A route applies to every hub that sits on both + `from_subnet` and `to_subnet`. The `reason` field is required for auditability. +- **Required fields per entry:** + - `from_subnet` (string, CIDR) — Source subnet. + - `to_subnet` (string, CIDR) — Destination subnet. + - `proto` (string) — Protocol: `"tcp"`, `"udp"`, or `"any"`. + - `reason` (string) — Human-readable justification. +- **Optional fields:** + - `ports` (array of integers) — Required when `proto` is `"tcp"` or `"udp"`. +- **Example:** + ```json + "routes": [ + { "from_subnet": "82.5.173.0/24", "to_subnet": "10.88.128.0/24", "proto": "tcp", "ports": [22, 80, 443], "reason": "Public services on LAN" }, + { "from_subnet": "10.88.127.0/24", "to_subnet": "10.88.128.0/24", "proto": "any", "reason": "WG clients reach LAN" } + ] + ``` + +### `requires_routes` (optional, default `[]`) + +- **Type:** Array of objects +- **Description:** Declares that this host needs a route from `via_subnet` to `to_subnet`. + The registry and horizon transformer validate that such a route exists or suggest the hub + that provides it. If the host is already on `to_subnet` (via its own coordinate), no route + is required — skipped automatically. Multi-hop BFS pathfinding is used when no single hub + spans both subnets. +- **Required fields per entry:** + - `via_subnet` (string, CIDR) — The subnet the host is on (the entry point). + - `to_subnet` (string, CIDR) — The target subnet the host needs to reach. + - `reason` (string) — Human-readable justification. +- **Example:** + ```json + "requires_routes": [ + { "to_subnet": "10.88.128.0/24", "via_subnet": "10.88.127.0/24", "reason": "remote-worker needs to reach the LAN" } + ] + ``` + +### `vhost_planes` (optional, default `{}`) + +- **Type:** Object keyed by vhost name (string), values are arrays of plane entries +- **Description:** Declares which planes each virtual host (vhost) is served on. Each + vhost entry is a list of `{ plane_name, subnet, reason, proxy_to? }` objects — one per + plane the vhost is reachable on. This drives per-subnet nginx vhost stanzas. +- **Required fields per vhost entry:** + - `plane_name` (string) + - `subnet` (string, CIDR) + - `reason` (string) +- **Optional fields per vhost entry:** + - `proxy_to` (string) — Backend in `"ip:port"` format. If present, the generator emits + `proxyPass`. If absent, the vhost is static (operator fills in `root` in the machine's + Nix config). +- **Example:** + ```json + "vhost_planes": { + "code.johnbargman.net": [ + { "plane_name": "cortex-alpha.lan", "subnet": "10.88.128.0/24", "proxy_to": "10.88.127.3:80", "reason": "Gitea on LAN" }, + { "plane_name": "wg", "subnet": "10.88.127.0/24", "proxy_to": "10.88.127.3:80", "reason": "Gitea on WG" } + ] + } + ``` + +### `default_response` (optional, default `"404-or-drop"`) + +- **Type:** String +- **Description:** The default HTTP response for vhosts not explicitly configured. The value + `"404-or-drop"` returns a 404 for HTTP and drops the connection for non-HTTP traffic. + This prevents ALPN leakage. Future values may be added (e.g., `"444"`, `"deny"`). +- **Example:** + ```json + "default_response": "404-or-drop" + ``` + +### `advertised_tailscale_routes` (optional, default `[]`) + +- **Type:** Array of strings (CIDR notation) +- **Description:** Subnets to advertise to the Tailscale mesh. The registry emits a warning + if any subnet in this list is NOT in the host's own coordinate (Tailscale ACL drift + detection). Each entry should be a /32 for a single host or a larger subnet for routing. +- **Example:** + ```json + "advertised_tailscale_routes": ["10.88.128.0/24", "10.88.127.0/24"] + ``` + +### `public_key_file` (optional, default `null`) + +- **Type:** String (path) or null +- **Description:** Path (relative to the repository root) to the WireGuard public key file + for this host. If non-null, the file MUST exist on disk (enforced by the registry). + Convention: `"secrets/public_keys/wireguard/wg__pub"`. +- **Example:** + ```json + "public_key_file": "secrets/public_keys/wireguard/wg_cortex-alpha_pub" + ``` + +### `_` (optional, documentation comments) + +- **Type:** String +- **Description:** A documentation comment field. Not consumed by any transformer; purely + for human readers.

Key +milestones: + +- **Phase -2 (Data Cleanup):** Per-host JSON files were created from the existing LAN + hosts. Sub-hub data was extracted. Public key files were mapped to the WG peer identifier + convention. `_`-prefixed fields were consolidated into `_legacy` objects. The `role` field + was removed from per-host files (the registry derives it from `hub_of` and `parent`). + Plane names were standardized to `cortex-alpha.lan` convention. The `trust` field was + added based on max coordinate trust. + +- **Phase -1 (Nix-to-JSON Conversion):** The old `topology/cortex-alpha.nix` and + `topology/shared.nix` were converted to JSON manually. Both formats coexist during + migration. + +- **Phase 0a (Registry as Dormant Code):** `lib/topology/mkRegistry.nix` was implemented + as a standalone validator. Not yet wired into any machine's evaluation. + +- **Phase 0b (Registry Wired):** The registry is consumed by `core-router-topology.nix` + instead of the raw Nix `import`. A `useNewPipeline` flag in `flake.nix` toggles between + the old pipeline (Nix files) and the new pipeline (JSON files + registry). + +- **Phase A (Schema Additions):** This document and `topology/_template.json` were created. + `lib/topology/mkHorizons.nix` was implemented. + +**Current state:** + +- The old schema (`.nix` files) is preserved in `topology/cortex-alpha.nix` and + `topology/shared.nix` for reference but is **not the source of truth**. +- The new schema (`.json` files) in `topology/` is the canonical source of truth. +- A `useNewPipeline` flag in `flake.nix` allows toggling between the two pipelines for + safe migration. ## Adding New Machines -To add a new machine to the topology system: - -1. **Update Topology File**: Add the new host to `real-topology/.nix` under `lan.hosts` - - Assign a unique IP within the subnet - - Set MAC address if known - - Configure routing flags (`tailscale`, `wireguard`) - - Add service tags if applicable - -2. **Add to WireGuard Peers**: If `wireguard = true`, add hostname to `wireguard.peers` list - -3. **Configure Firewall**: Add interface-specific rules in `firewall.interfaces` if needed - -4. **Update DNS**: Add static DNS entries in `dns.static` for services on the new machine - -5. **Add Nginx Proxies**: If exposing services, add entries to `nginx.proxies` - -6. **Validate**: Run `nix flake check` to ensure no syntax errors and validation passes +To add a new machine to the planar topology: -7. **Generate Golden**: Update the golden file: `nix run .#generate-golden -- > real-topology/golden/.json` +1. **Copy the template:** `cp topology/_template.json topology/.json` +2. **Fill in the fields:** Set `hostname`, `role`, `trust`, and at least one `coordinate` + entry.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 4-1.0 (BLOCKER): Restore genNginx.nix to two-arg form (settings, hostname) → { services.nginx = ... }. Fixes cortex-alpha evaluation crash at core-router-topology.nix:50. Both paths supported: vhostPlanes (new schema) and legacy nginx.proxies/baseVhosts. Phase 4-1.1: vhostPlanes (camelCase) canonical everywhere. _template.json: remove stale _, role, vhost_planes; add vhostPlanes. Schema docs: vhost_planes → vhostPlanes. mkNginxSettings.nix: remove dead usesNewSchema flag. mkHorizons.nix: fix host.vhost_planes → host.vhostPlanes (was snake_case). All 5 unit test suites pass. cortex-alpha dump-config produces valid JSON. --- documentation/topology-schema.md | 4 +- lib/topology/genDns.nix | 14 +- lib/topology/genDnsmasqHorizons.nix | 20 +- lib/topology/genNftablesMatrix.nix | 147 ++++---- lib/topology/genNginx.nix | 161 +++++++-- lib/topology/mkHorizons.nix | 339 +++++++++--------- lib/topology/mkNginxSettings.nix | 17 +- lib/topology/mkRegistry.nix | 485 +++++++++++++++----------- tests/topology/genDnsmasqHorizons.nix | 14 +- tests/topology/genNftablesMatrix.nix | 9 +- tests/topology/genNginx.nix | 51 +-- tests/topology/mkHorizons.nix | 272 ++++++++------- tests/topology/mkRegistry.nix | 287 ++++++++------- topology/_template.json | 7 +- 14 files changed, 1053 insertions(+), 774 deletions(-) diff --git a/documentation/topology-schema.md b/documentation/topology-schema.md index 0a59f598..b9121130 100644 --- a/documentation/topology-schema.md +++ b/documentation/topology-schema.md @@ -177,7 +177,7 @@ ] ``` -### `vhost_planes` (optional, default `{}`) +### `vhostPlanes` (optional, default `{}`) - **Type:** Object keyed by vhost name (string), values are arrays of plane entries - **Description:** Declares which planes each virtual host (vhost) is served on.

R3 (hub sort): when qualifying hubs exist → return [] (no error), not an error string. Previously inverted — returned errors when routes WERE satisfiable. R4 (BFS multi-hop): when BFS path exists → return [] (no error). Same inversion fixed. Also fixed BFS queue destructuring key mismatch (n → node). 6 new unit tests: valid hub, no hub, valid BFS, no BFS, missing fields, local subnet. All 17 mkHorizons tests pass. Phase 4-1.4: Fix genNftablesMatrix WAN detection. CGNAT: expand from 100.64.x.x to full 100.64.0.0/10 range (second octet 64-127). IPv6 ULA (fc00::/7): add isIpv6Ula check, treated as private. IPv6 link-local (fe80::/10): add check, treated as private. IPv6 documentation (2001:db8::/32): add check, not classified as WAN. 19 new subnet classification tests.

Fix remaining fidelity gaps: - Disable interface config from coordinates (out-of-scope for PONR; wireg0/tailscale0 managed by respective modules) - Add listenAddresses passthrough for vhost entries - Add conditional proxy_headers flag (cortex-alpha needs them, gaming-host-1 doesn't) - Resolve static root paths to absolute Nix store paths (fixes serializer artifact) - Restore enp3s0 interface block on cortex-alpha (PONR-2 removed expecting topology-derive but interfaces disabled for PONR) - Restore recommendedProxySettings/recommendedTlsSettings on gaming-host-1 (PONR-2 over-neutralized them) - Neutralize remote-worker inline nginx in flake.nix (missed by PONR-2 competing sources pass) Golden suite: 5 PASS_IDENTICAL, 11 PASS_NIXPKGS_DRIFT Zero FAIL_TOPOLOGY, Zero FAIL_EVAL.

We are using the right mechanism (`serviceOverrides` + `lib.mkForce`) but copying three shell scripts creates a **maintenance burden** that grows with every nixpkgs update. - -**Recommendation:** The Phase Overlord-I override (copy scripts) is acceptable as **temporary tactical measure**. However, we should immediately pursue **Phase II (custom module)** because: - -1. **Script copies are fragile** — nixpkgs module changes break silently -2. **Phase II is not blocked** — we can build it in parallel with Phase I -3. **The problem is architectural, not tactical** — no simple patch fixes it - ---- - -## Question 1: Is `serviceOverrides` with `lib.mkForce` the Right Approach? - -### Answer: Yes, But With Caveats - -`serviceOverrides` is the **correct NixOS lever** for this problem. It's designed for exactly this use case: overriding systemd service directives without replacing the entire module. - -```nix -serviceOverrides = { - ExecStartPre = lib.mkForce [ - "+${customUnconfigure}" - "${customConfigure}" - "${customSetupWorkDir}" - ]; -}; -``` - -**Why this is right:** -- `lib.mkForce` bypasses module priority rules, ensuring our override wins -- The `+` prefix runs the unconfigure script as root (needed for state cleanup) -- `ExecStartPre` is the correct systemd hook for pre-start checks - -**Why we can't do better with NixOS mechanisms:** -- `lib.mkOrder` doesn't work here (we need total replacement, not ordering) -- We can't override *part* of the ExecStartPre sequence — systemd requires the full list -- Module import order can't help (the github-runner module is final authority) -- There's no NixOS option to "modify a script in place" - -**Verdict:** This is the **correct mechanism**. The problem is what we're overriding — not *how*. - ---- - -## Question 2: Can We Avoid Copying All Three Scripts? - -### Answer: No. We Must Override All Three, But With Strategic Nesting - -The **root issue:** nixpkgs passes three scripts as an *ordered sequence* to `ExecStartPre`. Systemd executes them in order: - -```bash -ExecStartPre=+${unconfigure} # Runs as root -ExecStartPre=${configure} # Runs as the github-runner user -ExecStartPre=${setupWorkDir} # Sets up symlinks -``` - -We **cannot override just the unconfigure script** because: -1. If we keep the original unconfigure, it still wipes `.credentials` and `.runner` -2. If we only override unconfigure, the other scripts must still be compatible -3. The three scripts share state (`$STATE_DIRECTORY`) — changes cascade - -**However, we can reduce duplication:** - -Instead of copying the entire nixpkgs scripts, we could: - -```nix -# Option A: Wrap the original unconfigure script -customUnconfigure = pkgs.writeShellScript "gh-runner-unconfigure-patched" '' - # Preserve registration if already configured - if [[ -f "$STATE_DIRECTORY/.credentials" ]]; then - echo "Runner registered, skipping unconfigure" - exit 0 - fi - # Fall back to original for first-time setup - exec ${github-runner.unconfigure-original} -'' - -# Option B: Use sed/patch to modify the original script -customUnconfigure = pkgs.runCommandCC "unconfigure-patched" {} '' - ${pkgs.gnused}/bin/sed 's/clean_state()/# clean_state() disabled/' \ - ${github-runner.scripts.unconfigure} > $out - chmod +x $out -'' -``` - -**Verdict:** We **cannot avoid copying all three scripts** because they must work as a unit. However, we can **reduce duplication by wrapping or patching** the original scripts. This is a **minor optimization** — still requires vendoring the upstream code. - ---- - -## Question 3: Is There a Way to Patch the Module Instead of Replacing Scripts? - -### Answer: Not Cleanly. Here's Why. - -We explored three alternatives: - -#### Option A: Use an Overlay to Patch nixpkgs Module -```nix -nixpkgs.overlays = [(final: prev: { - github-runner = prev.github-runner.overrideAttrs (old: { - scripts = old.scripts // { - unconfigure = patched-unconfigure; - }; - }); -})] -``` - -**Problem:** The `github-runner` *module* (not package) is in `nixpkgs/nixos/modules/...`. Module code doesn't have an overlay path. You can't overlay NixOS modules directly — only packages. - -#### Option B: Use `disabledModules` to Disable + Replace -```nix -disabledModules = ["services/continuous-integration/github-runner"]; -imports = ["./modules/custom-github-runner.nix"]; -``` - -**Problem:** This is Phase II work. We'd have to copy the *entire* module (not just scripts). It's the right long-term solution but overkill for a tactical hotfix. - -#### Option C: Module Arguments/Options Override -```nix -# Some NixOS modules allow extending behavior via options -services.github-runners.hate-filled = { - preserveRegistrationScript = true; # hypothetical option -}; -``` - -**Problem:** The nixpkgs module doesn't expose this option. We can't add NixOS options to an upstream module without redefining it locally. - -**Verdict:** **There is no clean patch path.** The nixpkgs module is not designed for surgical overrides of the script logic. Our options are: - -1. **Phase I (Current):** Override `ExecStartPre` with custom scripts (brittle but minimal) -2. **Phase II (Proper):** Disable the module + use our own (requires copying entire module, but future-proof) -3. **Upstream:** File a PR against nixpkgs to add a `preserveRegistration` option (not our problem to solve) - ---- - -## Question 4: What's the Minimal Change That Fixes the Problem? - -### Answer: Override Just `ExecStartPre`, But Do It Carefully - -The **minimal working override** is: - -```nix -serviceOverrides = { - ExecStartPre = lib.mkForce [ - "+${pkgs.writeShellScript "gh-unconfigure-preserve" '' - # Skip unconfigure if runner is already registered - if [[ -f "$STATE_DIRECTORY/.credentials" ]]; then - exit 0 - fi - # On first boot: prepare token for configure step - install --mode=666 "${tokenFile}" "$STATE_DIRECTORY/.new-token" - ''}" - ]; -}; -``` - -**What this does:** -- Removes the `diff_config()` check that compares nix store paths -- Preserves `.credentials` and `.runner` across config changes -- Still configures on first boot (token exists → configure runs) - -**What it doesn't do:** -- Doesn't modify the `configure` or `setupWorkDir` scripts (they already handle the idempotence) -- Doesn't touch the nixpkgs module — just overrides one systemd directive - -**Why this works:** -1. `ExecStartPre` runs before every start -2. Our override checks if `.credentials` exists (sign of prior registration) -3. If yes → skip all steps, let the service start -4. If no → prepare the token, let `configure` run - -**Risk:** If nixpkgs changes the `configure` or `setupWorkDir` behavior, we might miss it. But those are less likely to change than the `unconfigure` logic. - -**Verdict:** This is the **true minimal fix**. It's a **single-script override** that doesn't require copying configure/setupWorkDir. However, if nixpkgs already has coupled logic between all three scripts, we still need all three. - ---- - -## Question 5: Is There Upstream Movement on This Issue? - -### Answer: Unlikely. The Problem is Architectural, Not a Bug. - -**Nixpkgs Design Philosophy:** -The module *intentionally* tears down and rebuilds runner state on every config change. The assumption is: -- "Config changes might affect runner behavior" -- "Better to re-register than risk inconsistency" - -**Why nixpkgs suggests PATs instead:** -- Registration tokens expire (1 hour) -- Re-registration with PATs is more reliable (PATs don't expire) -- Security concern ignored (PATs are overprivileged) - -**Has anyone reported this?** - -I cannot search the nixpkgs issue tracker from this environment, but based on the problem statement: -- The issue is **real** (we just experienced it on LINDA) -- It's **architectural** (not a simple bug) -- The **suggested fix (PAT) is worse than the problem** (security regression) - -**What an upstream PR would look like:** - -```nix -# Hypothetical nixpkgs enhancement -services.github-runners. = { - # ... - preserveRegistration = lib.mkOption { - description = "Keep runner registered across config changes"; - type = lib.types.bool; - default = false; # Safe default - }; -}; -``` - -**Our position:** We should **not wait for upstream**.

Nothing else. - ---- - -## Executive Summary - -This document analyzes risks for implementing a module override that fixes the nixpkgs `github-runner` module's destructive registration behavior. The nixpkgs module destroys persistent runner registration on every config change + reboot by running `config.sh destroy` before `run.sh run`. Our override modifies `ExecStartPre` to preserve registration state. - -**CRITICAL SECURITY CONSTRAINT:** This implementation uses registration tokens (ephemeral, 1-hour expiry), NOT personal access tokens (PAT). PATs are never acceptable. The security model depends on this distinction. - ---- - -## 1. NIXPKGS MODULE UPDATE RISKS - -### 1.1 Interface Drift - -**Risk:** When nixpkgs updates the `github-runner` module, the override may break silently or catastrophically. - -**Breakage Scenarios:** - -| Change Type | Impact | Detection Difficulty | -|-------------|--------|---------------------| -| `ExecStartPre` path/format change | Override targets wrong command; registration loop or silent failure | High (runtime only) | -| New `ExecStartPre` steps added | Pre-existing steps run BEFORE our preservation check; state still destroyed | Medium | -| Module renamed or restructured | Override has no effect; runners re-register every boot | Low (audit catches) | -| `serviceOverrides` attribute renamed | NixOS module error on eval | Low (caught at build) | - -**Detection Strategy:** -```nix -# Verify override is actually applied at eval time -assertion = config.services.github-runners..serviceOverrides.ExecStartPre != null; -``` - -**Mitigation:** Pin nixpkgs version in flake inputs. Monitor nixpkgs-channels for github-runner module changes. - -### 1.2 Store Path Compatibility - -**Risk:** The nixpkgs module uses hardcoded nix store paths (e.g., `/nix/store/...-github-runner-2.4.6/run.sh`). Our override script must reference these paths correctly. - -**Failure Mode:** -- Original: `${pkgs.github-runner}/bin/github-runner-runner.sh` -- Hardcoded in module: `/nix/store/...-github-runner-2.4.6/bin/Runner_ */run.sh` -- If our script assumes a different store path, runner fails to start - -**Mitigation:** -- Always use `config.services.github-runners..package` to derive correct paths -- Never hardcode store paths in override scripts -- Test with `nix build` before deployment - ---- - -## 2. TOKEN LIFECYCLE RISKS - -### 2.1 Token Expiry Before First Boot - -**Risk:** Registration token (1-hour expiry) expires before the machine boots and attempts registration. - -**Scenario:** -1. Token generated at T+0 -2. Machine built, deployed, powered off -3. Machine booted at T+1:05 (token expired) - -**Failure Mode:** -- Runner fails to register -- Service enters crash loop -- No recovery without new token - -**Mitigation:** -- Token refresh mechanism via secrix (token file updated before boot) -- Or: Use PAT-free registration token rotation via GitHub API -- Or: Accept boot dependency on token freshness (deploy then boot immediately) - -### 2.2 Token Expires During Registration - -**Risk:** Token expires mid-registration. - -**Scenario:** -1. Registration begins (token valid) -2. Network latency delays step 3 -3. Token expires before registration completes - -**Failure Mode:** -- Partial registration state in `.credentials` -- GitHub shows runner as "never contacted" (ghost runner) -- Re-registration attempts fail (token invalid) - -**Mitigation:** -- Implement retry with fresh token detection -- Check token freshness before registration attempt: - ```bash - TOKEN_AGE=$(date -d "$(stat -c %y "$TOKEN_FILE")" +%s) - CURRENT_AGE=$(date +%s) - if (( CURRENT_AGE - TOKEN_AGE > 3500 )); then # 58 min buffer - exit 1 # Token too old, fail fast - fi - ``` - -### 2.3 Missing Token File - -**Risk:** `tokenFile` path doesn't exist at service start. - -**Failure Modes:** -| Cause | Behavior | Recovery | -|-------|----------|----------| -| secrix decryption failed | Service fails to start; systemd marks dead | Manual intervention | -| Path wrong in config | NixOS eval error (caught early) | Fix config | -| File deleted between eval and run | Runner crashes; restart loop | Check file existence in ExecStartPre | - -**Mitigation:** -```bash -# In ExecStartPre, before ANY registration attempt -if [ ! -f "$TOKEN_FILE" ]; then - echo "FATAL: Token file $TOKEN_FILE not found" >&2 - exit 1 -fi -``` - ---- - -## 3. STATE DIRECTORY PERMISSIONS - -### 3.1 Permission Model Summary - -| Operation | User | Purpose | -|-----------|------|---------| -| `config.sh unconfigure` | root (`+` prefix) | Clean up service user credentials | -| `run.sh run` | service user | Register and run runner | -| `.credentials` directory | service user | Stores registration | - -**Critical Insight:** The `+` prefix on `ExecStartPre` runs that step as root. This is required for `config.sh unconfigure` to work correctly (it needs to operate on files owned by the service user). Our preservation logic runs as root when using `+`. - -### 3.2 Permission Failure Modes - -**Risk 1:** Service user cannot read `.credentials` after root modifies it -```bash -# If unconfigure runs (as root), it may change ownership -# Then run.sh (as service user) cannot access -``` -**Mitigation:** Never let unconfigure run. Our override prevents this. - -**Risk 2:** Root-owned token file unreadable by service user -**Actual:** Token file is world-readable (secrix decrypts to mode 0644). This is acceptable since the token is already exposed to the runner process. - -**Risk 3:** State directory permissions prevent registration update -**Actual:** State dir is `0750` owned by service user. Root can still access via `+`. - ---- - -## 4. RECOVERY SCENARIOS - -### 4.1 Corrupted `.credentials` File - -**Risk:** `.credentials` exists but is corrupted (partial write, disk error). - -**Detection:** -```bash -# In ExecStartPre, before deciding to preserve -if [ -f "$CREDENTIALS_FILE" ]; then - # Verify it's valid JSON and has expected fields - if ! python3 -c "import json; json.load(open('$CREDENTIALS_FILE'))" 2>/dev/null; then - # Corrupted or invalid - rm -f "$CREDENTIALS_FILE" - fi -fi -``` - -**Recovery:** If corrupted, the runner will re-register (creating new `.credentials`). This is acceptable behavior. - -### 4.2 Registration Succeeds But Runner Crashes Before Starting - -**Risk:** Runner registers with GitHub, gets `.credentials`, then crashes before the `run.sh` main loop starts. - -**Scenario:** -1. `run.sh run` starts -2. Token read, API call succeeds -3. `.credentials` written -4. Runner process crashes (OOM, SIGKILL, etc.) -5. Service restarts -6. GitHub shows runner as "offline" but registered - -**Failure Mode:** -- Ghost runners accumulate on GitHub -- Each reboot/crash creates orphaned runner entries -- Runner eventually starts but appears as "first connection" to GitHub - -**Mitigation:** -- Implement graceful shutdown handler -- Use systemd `TimeoutStartSec` to allow registration to complete -- Periodically clean ghost runners via GitHub API (CI job) - -### 4.3 Runner Registered But Token File Missing at Subsequent Boots - -**Risk:** Registration persists across reboots (good!), but token file is missing on reboot. - -**Scenario:** -1. First boot: Token file exists, registration succeeds, `.credentials` created -2. Token file deleted/corrupted -3. Reboot -4. Runner cannot re-register (no token), but `.credentials` still valid - -**Actual Behavior:** Runner uses `.credentials` to reconnect without token! This is the intended persistence behavior. - -**Edge Case:** GitHub may have expired the runner registration (if `disableAuto退役` is not set). In this case, runner falls back to attempting re-registration (which fails without token). - ---- - -## 5. TESTING STRATEGY - -### 5.1 Unit Testing (Override Logic) - -```nix -# Test: Preserved state is detected correctly -testPreservationLogic = import ./test-github-runner-preservation.nix; -testPreservationLogic = { - hasCredentials = { - input = { credentialsExist = true; credentialsValid = true; }; - expected = "preserve"; - }; - noCredentials = { - input = { credentialsExist = false; }; - expected = "register"; - }; - corruptedCredentials = { - input = { credentialsExist = true; credentialsValid = false; }; - expected = "register"; - }; -} -``` - -### 5.2 Integration Testing - -**Test Harness Requirements:** -1. VM with github-runner module override applied -2. Mock GitHub API (or use test organization) -3. Simulate: - - Fresh registration - - Config reload (should NOT re-register) - - Reboot (should NOT re-register) - - Corrupted credentials (should re-register) - - Missing token file (should fail gracefully) - -**Test Cases:** -| Test | Expected Outcome | -|------|------------------| -| Fresh boot, token valid | Registration succeeds | -| Config reload | No re-registration; runner continues | -| Reboot | No re-registration; runner reconnects | -| Corrupted `.credentials` | Re-registration, new `.credentials` | -| Token expired | Fail at ExecStartPre (detected early) | -| Missing token file | Fail at ExecStartPre (detected early) | - -### 5.3 Smoke Test (Manual) - -```bash -# On deployed machine: -systemctl status github-runner- -journalctl -u github-runner- -n 50 | grep -E "(credentials|register|token)" -# Verify: No "config.sh destroy" in logs after initial registration -``` - ---- - -## 6. SECURITY CONSIDERATIONS - -### 6.1 Registration Token vs PAT - -**Registration Token Properties:** -- Ephemeral: 1-hour expiry -- Scoped to: Organization + repository -- Cannot: Access source code, manage other runners, view secrets -- Can: Register a runner, receive work, report status - -**PAT Properties (NEVER USE):** -- Long-lived: No automatic expiry -- Scoped to: Whatever scopes were granted -- Can: Full API access, source code access, secret management -- Risk: Token exfiltration = full account compromise - -**Enforcement:** -- Code review: PAT usage is a blocking review comment -- Linting: Reject any `tokenFile` content that resembles a PAT pattern -- Monitoring: Log token source on service start - -### 6.2 Token File Permissions - -**Current Model:** secrix decrypts to world-readable file (`0644`) - -**Acceptability:** YES, because: -- Runner process already has access to the token (needed for registration) -- Token is useless after expiry (1 hour) -- Alternative (0600) prevents even reading for debugging - -**Risk:** Malicious local user reads token, registers their own runner within the hour - -**Mitigation:** Local user mitigation is out of scope (local users already have runner code execution). Token expiry limits exposure window. - ---- - -## 7. DEPLOYMENT CHECKLIST - -Before deploying the override: - -- [ ] Override evaluated against current nixpkgs version -- [ ] `ExecStartPre` path tested in VM -- [ ] Token refresh mechanism confirmed working with secrix -- [ ] Permission model verified (root vs service user) -- [ ] Corrupted credentials detection implemented -- [ ] Missing token file detection implemented -- [ ] Integration test suite passes -- [ ] Golden test generated (if applicable) -- [ ] Rollback plan documented - ---- - -## 8.

RECOMMENDATIONS - -### High Priority -1. **Pin nixpkgs version** for github-runner deployments until override is proven stable -2. **Implement token age check** in ExecStartPre (fail fast if token > 50 minutes old) -3. **Verify `.credentials` validity** before deciding to preserve state - -### Medium Priority -4. **Add integration tests** that simulate all failure modes -5. **Document token refresh procedure** for operators -6. **Create ghost runner cleanup** CI job - -### Low Priority (Nice to Have) -7.

Registration tokens are the correct scoped approach. - ---- - -## 1. Executive Summary - -The upstream nixpkgs `github-runner` module (`service.nix`) unconditionally destroys persistent runner state (`.credentials`, `.credentials_rsaparams`, `.runner`) on every configuration change or first-boot detection. This occurs because `diff_config()` compares the nix store path of `config.json`, which changes on every rebuild. The proposed solution — overriding `ExecStartPre` via `serviceOverrides` with `lib.mkForce` to inject conditional logic that preserves `.credentials` — is **correct and necessary**. - ---- - -## 2. Root Cause Analysis - -### 2.1 The Destruction Mechanism - -Three scripts execute sequentially in `ExecStartPre`: - -1. `unconfigureRunner` (runs as root via `+` prefix) -2. `configureRunner` -3. `setupWorkDir` - -### 2.2 `unconfigureRunner` — State Destruction Points - -```bash -runnerCredFiles = [ ".credentials" ".credentials_rsaparams" ".runner" ]; -``` - -**Path A — Ephemeral mode (line ~140):** -```bash -if [[ "${lib.optionalString cfg.ephemeral "1"}" ]]; then - clean_state # ALWAYS wipes stateDir -fi -``` - -**Path B — Non-ephemeral with existing state (line ~142):** -```bash -elif [[ "$(ls -A "$STATE_DIRECTORY")" ]]; then - diff_config # May call clean_state -fi -``` - -**Path C — First start (line ~145):** -```bash -else - copy_tokens # Only copies tokens, does NOT wipe -fi -``` - -**The `diff_config()` function (lines ~115-138):** -```bash -diff_config() { - changed=0 - # Check for module config changes via nix store path comparison - [[ -f "${currentConfigPath}" ]] \ - && ${pkgs.diffutils}/bin/diff -q '${newConfigPath}' "${currentConfigPath}" >/dev/null 2>&1 \ - || changed=1 - # Also check the content of the token file - [[ -f "${currentConfigTokenPath}" ]] \ - && ${pkgs.diffutils}/bin/diff -q "${currentConfigTokenPath}" ${lib.escapeShellArg cfg.tokenFile} >/dev/null 2>&1 \ - || changed=1 - if [[ "$changed" -eq 1 ]]; then - echo "Config has changed, removing old runner state." - clean_state # <-- DESTRUCTION HAPPENS HERE - fi -} -``` - -**`clean_state()` (lines ~108-113):** -```bash -clean_state() { - find "$STATE_DIRECTORY/" -mindepth 1 -delete # <-- NUCLEAR WIPE - copy_tokens -} -``` - -### 2.3 Why This Breaks on Every Rebuild - -- `newConfigPath` is generated via `builtins.toFile "${svcName}-config.json" ...` -- This creates a **new nix store path** on every evaluation -- `currentConfigPath` is `$STATE_DIRECTORY/.nixos-current-config.json` (symlink to previous store path) -- `diff -q '${newConfigPath}' "${currentConfigPath}"` **always fails** after a rebuild -- Result: `changed=1` → `clean_state()` → all `.credentials*` and `.runner` files deleted - ---- - -## 3. Proposed Override Approach — Correctness Verification - -### 3.1 The Conditional Preservation Logic - -The proposed override replaces `unconfigureRunner` with a version containing: - -```bash -# Skip wipe if .credentials exists (persistent registration) -if [[ -f "$STATE_DIRECTORY/.credentials" ]]; then - echo "Preserving existing runner registration (.credentials found)" - # Only update token file, do not touch .credentials/.runner - copy_tokens -else - # First-time registration path - if [[ ... ]]; then clean_state; else copy_tokens; fi -fi -``` - -### 3.2 Verification: This Is The Right Fix - -**Yes.** The conditional check on `.credentials` existence is the correct guard: - -1. **Semantic correctness:** `.credentials` is the canonical marker that the runner has successfully registered with GitHub. Its presence means the `.runner` file (containing `runnerId`, `agentName`) and `.credentials_rsaparams` are also valid. - -2. **Idempotency:** Re-running `configureRunner` is unnecessary and harmful if `.credentials` exists. The registration token is only needed once. - -3. **Token handling:** The token file copy (`copy_tokens`) is still required for `configureRunner` to detect "already configured" via absence of `.new-token`. The override correctly keeps this. - -4. **WorkDir cleanup:** The `find -H "$WORK_DIRECTORY" -mindepth 1 -delete` at the end of `unconfigureRunner` remains appropriate — workdir is ephemeral by design. - ---- - -## 4. Edge Case Analysis - -### 4.1 First Start (No `.credentials`) - -**Behavior:** -- `ls -A "$STATE_DIRECTORY"` is empty → falls through to `copy_tokens` -- `configureRunner` sees `.new-token` → executes `Runner.Listener configure` -- Creates `.credentials`, `.runner`, etc. -- **Result:** Correct first-time registration. - -**Override handling:** The proposed `if [[ -f "$STATE_DIRECTORY/.credentials" ]]` branch is skipped; falls to `else` which executes the original first-start logic. **Correct.** - -### 4.2 Recovery After Failed Registration - -**Scenario:** `configureRunner` fails (network error, invalid token, GitHub API 500). - -**Current upstream behavior:** -- `.new-token` is removed only on successful configure (line ~175) -- State directory may contain partial files from failed `Runner.Listener configure` -- Next boot: `diff_config` sees config change (or empty state) → `clean_state` → total wipe - -**Override behavior with `.credentials` guard:** -- If `.credentials` was never created (failed registration), guard fails → falls to original logic -- `clean_state` wipes partial state → fresh `copy_tokens` → retry registration -- **Result:** Correct recovery. The guard only protects *successful* registrations. - -**Recommendation:** The override should also guard against partial state. Consider checking for `.runner` existence as a secondary marker, or explicitly remove `.new-token` on failure within `configureRunner`. Current approach is acceptable but could be hardened. - -### 4.3 Token Expiry (Registration Token) - -**Constraint acknowledgment:** Registration tokens are valid for ~1 hour. This is a known limitation documented in `options.nix` (lines ~85-90). - -**Scenario:** System reboot after token expiry, but `.credentials` still exists. - -**Override behavior:** -- Guard `[[ -f "$STATE_DIRECTORY/.credentials" ]]` is true -- `copy_tokens` runs (copies *expired* token to `.new-token`) -- `configureRunner` sees `.new-token` → attempts `Runner.Listener configure --token ` -- GitHub API returns error → registration fails - -**Analysis:** -- This is **not a regression** introduced by the override. -- Upstream behavior with registration tokens is already broken after 1 hour (documented in options.nix). -- The override correctly preserves the *existing registration*. The runner continues to function with its current credentials until explicitly re-registered. -- **Correct behavior:** Do not reconfigure if `.credentials` exists. If re-registration is needed, the operator must delete `.credentials` manually (or implement a separate re-registration trigger). - -**No PAT suggestion permitted per constraints.** Registration tokens are the scoped, correct approach. Token refresh would require a separate mechanism (e.g., webhook-triggered re-registration or manual intervention). - -### 4.4 Config Change Without Re-Registration Intent - -**Scenario:** User changes `extraPackages`, `extraEnvironment`, or hardening options that do not affect runner identity. - -**Upstream behavior:** `diff_config` triggers on any `runnerRegistrationConfig` change → `clean_state` → death. - -**Override behavior:** Guard on `.credentials` prevents wipe. Runner continues with existing registration. **Correct and intended.** - ---- - -## 5. Security & Design Correctness - -### 5.1 Registration Token vs PAT - -**Confirmed:** The module's `options.nix` documentation (lines ~70-95) incorrectly suggests PATs as the "best option" and dismisses registration tokens due to 1-hour expiry. This is a **security regression**. - -- **Registration token scope:** Limited to `POST /actions/runner-registration` for a specific runner name. Cannot read/write repos, manage orgs, or perform other actions. -- **PAT scope:** Broad — `repo`, `admin:org`, or fine-grained PATs with "Read and Write access to self-hosted runners" still carry broader OAuth scopes than necessary. - -**Our position is correct:** Use registration tokens. The 1-hour expiry is a deployment-time constraint, not a runtime constraint. The override approach respects this by never re-invoking registration when `.credentials` exists. - -### 5.2 `serviceOverrides` with `lib.mkForce` - -The use of `lib.mkForce` on `serviceOverrides` is the correct integration point: - -- `serviceConfig` is built via `lib.mkMerge` (line ~70) -- `cfg.serviceOverrides` is the final item in the merge list (line ~280) -- `mkForce` ensures the override replaces the entire `ExecStartPre` list, not appends. - -This is the documented extension point in `options.nix` (lines ~140-150). - ---- - -## 6. Final Assessment - -| Criterion | Verdict | Justification | -|-----------|---------|---------------| -| Root cause identified | ✅ | `diff_config()` compares nix store paths → always triggers `clean_state()` | -| Destruction points mapped | ✅ | `clean_state()` via `find -mindepth 1 -delete` in three code paths | -| Conditional guard correct | ✅ | `.credentials` existence is the canonical "already registered" signal | -| First-start handled | ✅ | Guard fails → falls through to original `copy_tokens` + configure | -| Failed registration recovery | ✅ | No `.credentials` → original wipe + retry logic | -| Token expiry edge case | ✅ | Guard prevents re-registration with expired token; runner keeps working credentials | -| PAT recommendation avoided | ✅ | No PAT suggestions in analysis | -| `serviceOverrides` integration | ✅ | Documented extension point; `mkForce` replaces `ExecStartPre` correctly | - -**Conclusion:** The proposed override approach is **sound, minimal, and correct**. It surgically disables the destructive behavior while preserving all other module semantics. Deployment with registration tokens (not PATs) is the right architectural choice. - ---- - -**End of Review** \ No newline at end of file diff --git a/documentation/2026-07-09-REVIEW/2026-07-09-REVIEW.md b/documentation/2026-07-09-REVIEW/2026-07-09-REVIEW.md deleted file mode 100644 index b21dca11..00000000 --- a/documentation/2026-07-09-REVIEW/2026-07-09-REVIEW.md +++ /dev/null @@ -1,341 +0,0 @@ -# NixOS Configuration Codebase Review -**Date**: 2026-07-09 -**Branch**: `overlord-II` (HEAD: `31e4bfe`) -**Reviewer**: Commander (mimo-v2.5-pro) -**Scope**: Full codebase initialization and review - ---- - -## Executive Summary - -This is a **production-grade NixOS infrastructure** managing 19 machines across x86_64, aarch64, and armv7l architectures.

Either update it to use `serialize-config.nix` or remove it entirely. - -2. **Fix broken scripts** — `scripts/topology-report.sh` and `scripts/validate-new-architecture.sh` reference removed `real-topology/` paths. - -3. **Document Prometheus unlimited retention** — User decision to keep `retentionTime = "0d"`. Add monitoring for disk usage on local-nas. - -### Short-term (next development session) - -4. **Phase B: Fix WIP transformers** — `mkDnsSettings` needs correct subnet (`10.88.128.0/24`), real DNS entries, real DHCP hosts. `mkFirewallSettings` needs to consume topology firewall data. `mkNginxSettings` needs ACME logic fix. - -5. **Phase B: Wire core-router-topology.nix** — Test with cortex-alpha, validate golden output matches. - -6. **SSH multiplexing redesign** — Create custom module extending `programs.ssh` with `matchBlocks`, or use `extraConfig` approach. - -### Medium-term - -7. **Phase C: Library split preparation** — Create `lib/topology_library.nix` entry point. - -8. **GitHub runner custom module** — Build Phase 2 module that separates identity from config. - -9. **LLM-CORE re-enable** — Uncomment and test on LINDA and remote-worker. - -## Conclusion - -The topology rectification work is **structurally sound and well-executed**. The directory restructuring, import updates, and fleet deployment were done correctly with no regressions. Golden files were preserved byte-for-byte. - -However, the **core Phase B/C objectives were not addressed**. The WIP transformers remain skeletons with hardcoded/incorrect data.

These are non-blocking deprecation notices, but they indicate technical debt in configuration modules. The number of deprecation warnings is increasing with nixpkgs 25.11. - ---- - -## 3. Regression Risk: Root `topology.nix` Removal - -### 3.1 Functional Nix References - -**Verdict: ✅ PASS.** Specific grep for `import ./topology.nix` and `import ../topology.nix` returned **zero results** in `.nix` files. The root `topology.nix` was successfully eliminated without breaking functional imports. - -All Nix module references to `topology.nix` are file *names* (e.g., `enable-wg-topology.nix`, `core-router-topology.nix`) — these are the WIP module files and are correctly resolved. - -### 3.2 Broken Scripts (Functional Issue) - -**Verdict: ❌ FAIL.** Two scripts contain broken references to the old file structure: - -#### `scripts/topology-report.sh` (BROKEN) - -``` -Line 21: HAS_TOPOLOGY=$(nix eval --json "import ./topology.nix {} | ...") -Line 30: if [ -f "real-topology/golden/$machine.json" ]; then -Line 65: HAS_TOPOLOGY=$(nix eval --json "import ./topology.nix | ...") -Line 66: HAS_GOLDEN=$([ -f "real-topology/golden/$machine.json" ] && ...) -``` - -- `./topology.nix` no longer exists — it was moved to `topology/shared.nix` -- `real-topology/golden/` no longer exists — goldens moved to `goldens/` -- **Result:** This script will fail on lines 21 and 65 with `error: file 'topology.nix' not found` -- **Impact:** The coverage report cannot be generated.

Regression Risk: SSH Multiplexing Revert - -### 4.1 Leftover `ssh-mux` References in Nix Code - -**Verdict: ⚠ WARNING — 2 instances found in `machines/LINDA/default.nix`** - -#### Instance 1: SSH ControlPath (Line 50) -```nix -programs.ssh.extraConfig = '' - Host hyperhyper - ControlMaster auto - ControlPath /run/ssh-mux/%r@%h:%p - ControlPersist 600 -''; -``` - -#### Instance 2: tmpfiles Rule (Line 255) -```nix -systemd.tmpfiles.rules = [ - ... - "d /run/ssh-mux 0755 John88 users" -]; -``` - -**Analysis:** These references are NOT from the reverted overlord-II `mkMultiplexConfig` implementation — they are pre-existing LINDA-specific SSH configuration for a host named "hyperhyper". However: -- They use the same `/run/ssh-mux` path that the reverted plan specified -- They create the `/run/ssh-mux` directory via tmpfiles -- The `ControlMaster auto` / `ControlPath` / `ControlPersist 600` pattern IS an SSH multiplexing configuration - -**Risk:** LOW. This is a functional SSH multiplexing setup that happens to use the same path pattern as the reverted plan. It is operational and predates overlord-II. Not a regression from the revert. However, it's an untracked SSH multiplexing deployment that exists outside the topology framework. - -### 4.2 No `mkMultiplexConfig` or `matchBlocks` References - -**Verdict: ✅ PASS.** Grep for `mkMultiplexConfig` and `matchBlocks` in `.nix` files returned zero results. The revert was clean in terms of Nix code. Documentation files still reference these terms for historical context (which is appropriate). - ---- - -## 5. MaxSessions Revert - -### 5.1 sshd.nix - -**Verdict: ✅ PASS.** `environments/sshd.nix` line 28: -```nix -MaxSessions = 2; -``` - -Correctly reverted from 20 back to 2. No leftover references to `MaxSessions = 20` found anywhere in the codebase. - ---- - -## 6. Unintended Consequences: `topology/default.nix` - -### 6.1 Merge Logic Analysis - -```nix -# topology/default.nix lines 12-25 -machineFiles = { - cortex-alpha = import ./cortex-alpha.nix { inherit lib self; }; -}; - -topology = shared // lib.mapAttrs - (name: machineCfg: - let - sharedCfg = shared.${name} or { }; - in - sharedCfg // machineCfg - ) - machineFiles; -``` - -**Verdict: ✅ PASS.** The merge logic is correct: - -1. `shared` = all 22 entries from `shared.nix` (cortex-alpha, local-nas, alpha-one, etc.) -2. `lib.mapAttrs` iterates only over keys in `machineFiles` (only `cortex-alpha`) -3. For cortex-alpha: merges `shared.cortex-alpha` with `cortex-alpha.nix` (per-machine takes precedence via `//`) -4. `shared // mergedCortexAlpha` — replaces the shared cortex-alpha entry with the merged version -5. All other machines remain untouched from `shared` - -**No evaluation error risk for machines without per-machine files.** The `mapAttrs` function only touches keys present in `machineFiles`. - -### 6.2 `generateGolden` Delegation - -```nix -generateGolden = machineName: - let - generator = import ../lib/golden_generator.nix { inherit lib self; }; - in - generator.generateGolden machineName; -``` - -**Verdict: ❌ FORMAT MISMATCH — Confirmed via diff.** - -The `generate-golden` app calls `topology.generateGolden` → `lib/golden_generator.nix`, which produces a flat option-value structure. However, the golden files in `goldens/` were ALL generated with `dump-config` (which uses `lib/serialize-config.nix` — a different, more comprehensive serializer). These two serializers produce **drastically different output**. - -**Evidence from direct comparison:** - -`diff` between `dump-config` and `generate-golden` output for cortex-alpha reveals: - -1. **Size difference**: `dump-config` produces ~3,800 lines of comprehensive configuration; `generate-golden` produces ~600 lines (only the options in `safeOptions`) -2. **Missing sections in generate-golden**: Entire `boot.loader.*`, `networking.interfaces.*`, `networking.wireguard.*`, `services.nginx.*`, `security.acme.*` sections present in dump-config are either absent or radically different in generate-golden -3. **Path representation difference**: Store paths are rendered differently: - - `dump-config`: `"kernel.poweroff_cmd": "/d0y2...systemd-258.7/sbin/poweroff"` - - `generate-golden`: `"kernel.poweroff_cmd": "/nix/store/d0y2...systemd-258.7/sbin/poweroff"` -4. **Depth**: dump-config produces deeply nested JSON; generate-golden produces a flat key-value map - -**The `generate-golden` app is currently dangerous.** If someone runs: -```bash -nix run .#generate-golden -- cortex-alpha > goldens/cortex-alpha.json -``` -They would **irrevocably truncate the golden file** from ~3,800 lines to ~600 lines, corrupting the golden test. The `check-network` app correctly uses `dump-config` for comparison, which is why golden tests still pass — but `generate-golden` is a trap. - -**Recommendation (HIGH PRIORITY):** Either: -1. **Update `generate-golden`** to use `lib/serialize-config.nix` (making it consistent with `dump-config`) -2. **Or remove `generate-golden` entirely** — it's fully redundant with `dump-config` and actively dangerous - ---- - -## 7. Additional Findings - -### 7.1 Prometheus Retention Set to Unlimited - -**Verdict: ⚠ CONCERN.** `services/prometheus.nix` line 30: -```nix -retentionTime = "0d"; -``` - -This disables Prometheus data retention, meaning **data accumulates indefinitely**. Without a retention policy, disk usage grows monotonically until the storage volume is full. This is the Prometheus default, but the task description flagged it as a concern. - -- `retentionTime = "0d"` means "never delete data based on age" -- `retentionSize` is not set (defaults to 0, meaning unlimited) -- Combined effect: **truly unlimited retention** - -**Risk:** Gradual disk exhaustion on the monitoring host (`local-nas`, `10.88.127.3`). Over months of operation, this will consume significant storage. Particularly impactful with 17 machines sending node exporter data at 30s scrape intervals, plus ZFS, NVIDIA GPU, smartctl, and other exporters. - -**Recommendation:** Set a concrete retention policy: -```nix -retentionTime = "90d"; # or "180d" for longer history -retentionSize = "50GB"; # cap total storage -``` - -### 7.2 Stale `real-topology/` Comments - -**Verdict: ⚠ COSMETIC.** Three files contain stale `real-topology/` references in comments: - -| File | Line | Content | Impact | -|------|------|---------|--------| -| `lib/golden_generator.nix` | 1 | `# real-topology/default.nix` | LOW — comment only | -| `topology/cortex-alpha.nix` | 1 | `# real-topology/cortex-alpha.nix` | LOW — comment only | -| `tests/test-new-architecture.nix` | 52 | `# Import safeOptions from real-topology/default.nix` | LOW — comment only | - -These are non-functional but should be cleaned before the Phase C library split to avoid confusion. - -### 7.3 `golden_coverage.nix` Exclusion List Opaque - -**Verdict: ⚠ CODE SMELL.** `lib/golden_coverage.nix` line 6 excludes these machines from coverage: -```nix -nixosMachines = builtins.attrNames (builtins.removeAttrs self.nixosConfigurations [ - "beta-one" "display-0" "display-1" "display-2" "print-controller" - "bargman-greeter-vm" "arm-bootstrap" -]); -``` - -Notable: `display-1`, `display-2`, and `print-controller` ARE in `topology/shared.nix` and HAVE golden files in `goldens/`. The exclusion reasons are unclear — these machines appear fully capable of coverage. Only `beta-one`, `bargman-greeter-vm`, and `arm-bootstrap` are genuinely special (VM, ARM bootstrap). The exclusion list conflates multiple categories. - -**Recommendation:** Either add golden coverage for `display-1`, `display-2`, and `print-controller`, or document why they're excluded. - -### 7.4 WIP Architecture Status - -The WIP `core-router-topology.nix` is confirmed **not wired** into cortex-alpha per `AGENTS.md`. The production `core-router.nix` remains active for cortex-alpha. This is intentional and correct per Phase B sequencing. The WIP `core-router-topology.nix` will be integrated in a future step and MUST pass golden validation at that time. - ---- - -## 8.

All systems are healthy and operational. The deployment protocol was correct for the core router (cortex-alpha: dry-activate → test → switch). However, three operational risks require attention: - -1. **Prometheus unlimited retention** (`retentionTime = "0d"`) on cortex-alpha will consume disk at ~500 MB/week → disk exhaustion risk in ~11 months without mitigation -2. **Exporter state bug** — documented, understood, mitigation strategy available but not implemented -3. **SSH agent timeout** — session-specific, not a fleet-wide issue, but should be documented for operational playbooks - -**Status: Proceed with caution. Immediate action required on Prometheus retention policy before December 2026.** - ---- - -## 1.

The status document is complete and accurate. - ---- - -## 2. Exporter State Bug Analysis - -### ✅ Bug Understood and Documented - -From `modules/nixos-deployment-exporter.nix` (lines 344-365) and deployment status (lines 45-51): - -**Problem:** The `nixos-deployment-exporter` records a stale `system_path` in `/var/lib/nixos-deployment/state.json` after activation. - -**Root Cause:** The activation script (line 356) reads the system path BEFORE the symlink is fully updated during `--test` and `--switch`: - -```nix -system_path="$(${lib.getExe' pkgs.coreutils "readlink"} -f /run/current-system 2>/dev/null || true)" -if [ -z "$system_path" ]; then - system_path="$(${lib.getExe' pkgs.coreutils "readlink"} -f /nix/var/nix/profiles/system 2>/dev/null || true)" -fi -``` - -The fallback to `/nix/var/nix/profiles/system` (line 358) can return a path that hasn't been updated yet if `/run/current-system` fails or is delayed. - -**Observed Impact:** cortex-alpha and local-nas showed stale `system_path` in exporter metrics during overlord-II. - -**Source of Truth:** The exporter's own Python code (lines 200-205) confirms the fallback hierarchy: -```python -system_path = ( - state.get('system_path') - or meta.get('derivationPath') - or meta.get('flakeSource') - or 'unknown' -) -``` - -### ⚠️ Mitigation Strategy Available But Not Implemented - -**Tool Pattern 8** (from shared tool patterns) documents the workaround: -```bash -# Ground truth (use this instead of exporter metric) -ssh deploy@ "readlink /run/current-system" - -# May be stale (don't rely on this) -ssh deploy@ "cat /var/lib/nixos-deployment/state.json" -``` - -**Recommended Fix** (not implemented): - -Modify the activation script to ensure `/run/current-system` is explicitly resolved AFTER the switch completes: - -```bash -# Proposed (NOT DEPLOYED) -system_path="$(readlink -f /run/current-system)" -# Retry with backoff if the symlink isn't ready -for attempt in {1..5}; do - if [ -n "$system_path" ] && [ -e "$system_path" ]; then - break - fi - sleep 0.5 - system_path="$(readlink -f /run/current-system 2>/dev/null || true)" -done -``` - -**Verdict:** 🟡 **KNOWN ISSUE, DOCUMENTED, NOT BLOCKING** — The bug is pre-existing, understood, and documented in deployment status. Operators are advised to use `/run/current-system` as ground truth. Recommend implementing fix in next maintenance window (Phase B or later). - ---- - -## 3. Core Router Deployment Protocol - -### ✅ Three-Phase Protocol Followed Correctly - -From `documentation/overlord-II-deployment-status.md` (header: "Deployment method: `nix run .# -- switch`"): - -**Documented Protocol** (Tool Pattern 3): -1. `nix run .#cortex-alpha -- dry-activate` — Preview changes, no activation -2. `nix run .#cortex-alpha -- test` — Activate without boot entry, reboot reverts -3. `nix run .#cortex-alpha -- switch` — Permanent activation with boot entry - -**Evidence of Compliance:** - -From development report (lines 1-6): -- Base commit: `db90b5d` (pre-deployment) -- Head commit: `0902092` (post-deployment, visible in git log) -- Golden tests pass for cortex-alpha: ✅ (line 25) -- Flake validation passes: ✅ (line 24) - -From git log (2026-07-12): -- Latest commit: `0902092 docs: add overlord-II consolidated execution plan` (after deployment completion) -- Status: ✅ Healthy (from deployment status, line 12) - -**Risk Assessment:** - -The core router (cortex-alpha) is critical infrastructure: -- **IP:** 10.88.127.1 (WireGuard hub, DHCP server, DNS/DHCP authoritative) -- **Services:** dnsmasq, Prometheus, Grafana, nginx reverse proxies -- **Impact of failure:** Entire fleet loses DNS, DHCP, and inter-network connectivity - -**Deployment Risk: MINIMIZED** -- User was present during deployment (implied by manual LINDA switch in status) -- Three-phase protocol ensures testability before permanent boot entry -- Revert capability exists (reboot reverts test mode; no permanent boot entry until switch) -- No evidence of deployment errors or rollbacks - -**Verdict:** ✅ **CORRECT PROTOCOL APPLIED** — The core router deployment followed the documented three-phase protocol. No risks detected from deployment methodology. - ---- - -## 4. Prometheus Retention Policy Risk - -### 🔴 CRITICAL RISK: Unlimited Retention Policy - -From `services/prometheus.nix` (line 30): -```nix -retentionTime = "0d"; -``` - -**Meaning:** `"0d"` means "never delete historical data" — unlimited retention. - -**Location:** Deployed on **cortex-alpha** (core router) - -From commit `511141b` (2026-07-12, 07:56:41): -``` -commit 511141b -Author: John Bargman -Date: Sun Jul 12 07:56:41 2026 +0000 - -fix(prometheus): unlimited retention — metrics exist to be stored - -retentionTime = "0d" — never delete historical data. -``` - -### Disk Space Risk Analysis - -**Hardware:** cortex-alpha (from `machines/cortex-alpha/hardware-configuration.nix`) - -Filesystems: -- `/` (root): `/dev/disk/by-uuid/4dc79711-2a40-4d3d-9ea6-e390fb0f505c` (ext4) — size unknown -- `/nix`: `/dev/disk/by-uuid/ca8394dc-2c90-4236-8c8a-14665a0b1eb3` (ext4) — size unknown -- `/home`: `/dev/disk/by-uuid/0d9bd65d-1682-4d96-b364-5c21d4eed584` (ext4) — size unknown -- `/external`: ZFS pool "external" — size unknown - -**Prometheus Metrics Estimate:** - -From `services/prometheus.nix` scrape configs (lines 32-178): -- **Jobs:** postgres, nvidia, klipper, dnsmasq, node, zfs, nginx, nextcloud, nixos-deployment, smartctl -- **Scrape intervals:** 5s to 60s (default 30s) -- **Targets:** ~43 individual exporter targets across the fleet -- **Expected cardinality:** High (per-device metrics, per-core CPU metrics, ZFS pool/dataset metrics) - -**Conservative Estimate:** -- Time-series cardinality: 15,000–30,000 metrics (typical fleet monitoring) -- Ingestion rate: 40–60 samples/second (typical for 40+ targets at 30s intervals) -- Disk consumption: **~500 MB/week** (industry standard: 1-2 KB per sample in TSDB format) -- Monthly growth: ~2 GB/month -- **Disk exhaustion timeline: ~11 months from 2026-07-12 (May 2027) at typical fleet growth rate** - -### Storage Pressure Scenario - -If the `/` or `/nix` filesystem is a standard workstation SSD (512 GB to 2 TB): -- **At 11 months:** Prometheus alone consumes ~22 GB -- **With system updates and build artifacts:** Combined with nixpkgs updates, system derivations can exceed 50 GB -- **Critical threshold:** When filesystem reaches 85–90% capacity, system performance degrades (inode pressure, journal exhaustion) -- **Failure mode:** Prometheus cannot write state → metrics loss, query failures - -### Risk Severity: 🔴 CRITICAL - -**Justification:** -1. **Core service on critical infrastructure:** Prometheus runs on cortex-alpha (the hub) -2. **Silent growth:** Metrics accumulate without operator awareness; no automatic cleanup -3. **Impact:** Metrics loss cascades to Grafana dashboards, alerting, and operational visibility -4. **Timeline:** ~11 months before critical threshold (May 2027) - -### Recommended Mitigations (Priority Order) - -**IMMEDIATE (Within 1 week):** -1. Document Prometheus storage management in ops runbooks -2. Implement monitoring for `/var/lib/prometheus` disk usage (add alert when >50% filesystem usage) -3. Schedule quarterly Prometheus compaction/cleanup procedure - -**SHORT TERM (Within 4 weeks):** -1. Implement retention policy: `retentionTime = "30d"` (30-day rolling window) - - Keeps recent operational data (troubleshooting, trend analysis) - - Consumes ~4 GB/month (sustainable on typical disk) - - Aligns with industry best practice - -2. OR: Implement archival strategy - - Compress old Prometheus blocks every 7 days → separate NAS storage - - Keep hot 7 days on cortex-alpha, warm 30 days in archive - -**LONG TERM (Phase 3+):** -1. Deploy Prometheus cluster with dedicated storage node -2. Implement S3-compatible archival (MinIO or Hetzner S3) -3. Use Thanos or Cortex for long-term metric retention - -**Verdict:** 🔴 **ACTION REQUIRED BEFORE DEPLOYMENT** — Set `retentionTime = "30d"` and implement disk usage monitoring. Unlimited retention on critical infrastructure is a resource exhaustion risk. - ---- - -## 5. SSH Agent Timeout Risk - -### ⚠️ Session-Specific Issue, Not Fleet-Wide - -From deployment status (lines 43-51), no explicit documentation of SSH agent timeouts exists. However, Tool Pattern 8 mentions SSH multiplexing planning, which suggests SSH connection reliability is a known concern. - -**Expected Issue Pattern:** - -During long deployment sessions, SSH agent keys can time out if: -1. Session runs longer than `agentTimeout` default (15 minutes) -2. Agent process is recycled by systemd user-lingering -3. Multiple SSH connections exhaust agent connection pool - -**Observed During Overlord-II:** - -"SSH to local-nas failed with 'agent refused operation'. This was resolved by the user re-authorizing." - -**Root Cause Analysis:** - -This is likely caused by: -1. SSH agent timeout during the multi-machine deployment session (likely 30+ minutes) -2. User had to re-enter credentials or restart agent -3. Deployment completed successfully after re-auth - -**Risk Assessment:** - -| Risk Factor | Severity | Rationale | -|---|---|---| -| Fleet-wide impact | Low | Only affects SSH client sessions, not deployed systems | -| Frequency | Medium | Expected during long deployment sessions (>15 min) | -| Mitigation difficulty | Low | Well-understood SSH agent features | -| Operational cost | Low | Single re-auth per session | - -### Recommended Mitigation: Document Agent Configuration - -**Add to operations runbooks** (`documentation/operations-runbooks.md` or new `operations-ssh-agent.md`): - -```markdown -## SSH Agent Timeout Management - -### Symptom -"agent refused operation" during long deployment sessions. - -### Cause -SSH agent key timeout after 15 minutes of inactivity (default `agentTimeout`). - -### Prevention -1. Before starting deployment session, configure agent timeout: - ```bash - ssh-add -t 7200 ~/.ssh/id_ed25519_master # 2-hour timeout - ``` - -2. Or enable agent forwarding for long sessions: - ```bash - ssh-agent bash # Start new agent shell - ssh-add ~/.ssh/id_ed25519_master - # Run deployment - ``` - -3. Monitor agent status: - ```bash - ssh-add -l # List loaded keys - ssh-add -t 3600 ~/.ssh/id_ed25519_master # Refresh timeout - ``` - -### Escalation -If "agent refused operation" occurs mid-deployment: -1. Pause deployment -2. Re-authorize agent: `ssh-add ~/.ssh/id_ed25519_master` -3. Resume deployment (SSH connections will use renewed auth) -``` - -### SSH Multiplexing Plan (Tool Pattern 5) - -The `ssh-multiplex-topology-2026-07-03.md` plan addresses this issue systematically: - -**Current Status:** Planned but blocked (see Section 6). - -**When Implemented:** SSH multiplexing will: -- Reuse single authenticated connection for multiple operations -- Eliminate repeated agent timeouts on same host -- Reduce handshake overhead (150–500 ms per connection) - -**Verdict:** 🟡 **DOCUMENTED PATTERN EXISTS, ESCALATION SIMPLE** — SSH agent timeout is expected and manageable. Mitigation (multiplexing) is already planned. Recommend adding agent timeout guidance to ops runbooks. - ---- - -## 6. Tool Patterns Verification - -From `/speed-storage/opencode/llm/shared/tool-patterns-overlord-II-2026-07-12.md`: - -### Pattern 1: Golden Validation via dump-config (NOT generate-golden) - -**Status:** ✅ **VERIFIED AND APPLIED** - -Evidence: -- Fix committed in `4f80255` (overlord-II-development-report.md, line 36) -- Message: "fix: check-network uses dump-config (serialize-config.nix) to match golden format" -- All golden tests now pass (development report, line 14) - -**Accuracy:** Pattern is correct and complete. The distinction between `dump-config` (hierarchical) and `generate-golden` (flat) is critical for golden validation integrity. - -### Pattern 2: Verify Deployments via Derivation Outpath - -**Status:** ✅ **VERIFIED IN DEPLOYMENT STATUS** - -Evidence: -- All 12 deployed machines have system path outpaths documented (lines 10–23) -- Exporter verification method documented in status -- Fallback to `/run/current-system` explained (Tool Pattern 8) - -**Accuracy:** Pattern is correct. The distinction between exporter metric (potentially stale) and `/run/current-system` (ground truth) is important and documented. - -### Pattern 3: Core Router Deployment Protocol - -**Status:** ✅ **VERIFIED IN CORTEX-ALPHA DEPLOYMENT** - -Evidence: -- Three-phase protocol (dry-activate → test → switch) documented in Tool Pattern 3 -- No evidence of deployment errors or rollbacks -- Golden tests pass for cortex-alpha - -**Accuracy:** Pattern is correct and applied correctly. - -### Pattern 4: Verify Option Existence Before Implementation - -**Status:** ✅ **CONFIRMED VIOLATION AND FIX** - -Evidence: -- Violation documented in development report (lines 46–56) -- `programs.ssh.matchBlocks` does NOT exist in nixpkgs 25.11 -- Implemented in `0d79eea`, reverted in `8455cbe` -- Lesson learned: Always verify NixOS options against actual nixpkgs version before implementing - -**Accuracy:** Pattern is correct and validated by the overlord-II session itself. The pattern prevented a second wasted commit cycle. - -### Pattern 5: Worktree-Based Development - -**Status:** ✅ **APPLIED TO OVERLORD-II** - -Evidence: -- Development occurred on `overlord-II-exec` worktree (development report, line 4) -- Branched from `overlord-II` -- Multiple commits and reversions possible without affecting main repo - -**Accuracy:** Pattern is correct. Worktrees prevent file contention and merge conflicts. - -### Pattern 6: Parallel Independent Deploys - -**Status:** ⚠️ **NOT DISCUSSED IN OVERLORD-II, BUT APPLICABLE** - -Evidence: -- Overlord-II deployed 12 machines, no evidence of parallelization -- Machines are mostly independent (no shared backing services) -- Deployment likely sequential (typical nixinate behavior) - -**Recommendation:** Document parallelization strategy for future deployments (Phase C or later). - -### Pattern 7: Topology Rectification — Move Without Modifying - -**Status:** ✅ **APPLIED CORRECTLY** - -Evidence: -- Golden files moved from `real-topology/golden/` to `goldens/` (development report, lines 74–76) -- Content preserved: "zero bytes changed" -- No golden regeneration during refactoring - -**Accuracy:** Pattern is correct and critical for golden integrity. The development report confirms no golden files were modified. - -### Pattern 8: Exporter State Discrepancy Awareness - -**Status:** ✅ **DOCUMENTED AND UNDERSTOOD** - -Evidence: -- Issue documented in deployment status (lines 45–51) -- Workaround documented in Tool Pattern 8 -- Deployed systems (cortex-alpha, local-nas) showed expected stale behavior - -**Accuracy:** Pattern is correct. The exporter metric is a proxy; `/run/current-system` is ground truth. - -### Summary of Tool Pattern Verification - -| Pattern | Accuracy | Coverage | Completeness | -|---------|----------|----------|--------------| -| 1: Golden via dump-config | ✅ Correct | ✅ Full | ✅ Complete | -| 2: Verify via outpath | ✅ Correct | ✅ Full | ✅ Complete | -| 3: Core router 3-phase | ✅ Correct | ✅ Full | ✅ Complete | -| 4: Verify option existence | ✅ Correct | ✅ Full | ✅ Validated by session | -| 5: Worktree development | ✅ Correct | ✅ Full | ✅ Complete | -| 6: Parallel deploys | ⚠️ Correct | ❌ Not discussed | ⚠️ For future reference | -| 7: Topology move without modify | ✅ Correct | ✅ Full | ✅ Complete | -| 8: Exporter discrepancy | ✅ Correct | ✅ Full | ✅ Complete | - -**Verdict:** ✅ **PATTERNS ACCURATE AND COMPLETE** — Tool patterns are validated by overlord-II execution.

Operational Directives Compliance - -### Directive Violations Documented - -From `documentation/overlord-II-development-report.md` (lines 44–77): - -**VIOLATION 1: Implementing Without Verifying Prerequisites** -- **Directive:** Methodical Development — No Rushing (Directive 21, prime directives) -- **Violation:** SSH multiplexing implemented without verifying `programs.ssh.matchBlocks` exists -- **Impact:** Wasted commit cycle (committed in `0d79eea`, reverted in `8455cbe`) -- **Resolution:** Reverted. Pattern 4 now prevents this issue. -- **Status:** ✅ Acknowledged and corrected - -**VIOLATION 2: Golden Files Regenerated Before Session** -- **Directive:** "Golden tests are sacrosanct — never regenerate golden as part of refactoring" (AGENTS.md) -- **Violation:** Commit `db90b5d` regenerated 10 golden files -- **Impact:** Caused all golden tests to fail initially (generator mismatch) -- **Root Cause:** Two generators existed (`real-topology/default.nix` vs `serialize-config.nix`) producing incompatible formats -- **Resolution:** Fixed `check-network` to use correct generator (`dump-config`); golden files themselves were NOT modified in overlord-II session -- **Status:** ✅ Acknowledged and corrected - -### Golden Integrity Preserved - -From development report (lines 74–76): -> "The golden files from `v1.9-Golden` tag are byte-identical to the current `goldens/` directory." - -**Verification:** -- 18 golden files: ✅ Byte-identical to v1.9-Golden tag -- No golden files modified during overlord-II development -- No golden files modified during overlord-II deployment -- Golden validation: ✅ All 10 active machines pass - -**Verdict:** ✅ **GOLDEN INTEGRITY PRESERVED** — Despite pre-session violations, golden files remain sacrosanct. The session corrected the generator mismatch without modifying goldens. - ---- - -## 8. Outstanding Items & Blockers - -### Resolved Blockers - -**Blocker 1: check-network / generate-golden Mismatch** -- **Status:** ✅ RESOLVED (`4f80255`) -- **Fix:** Updated `check-network` to use `dump-config` instead of `generate-golden` - -**Blocker 2: programs.ssh.matchBlocks Doesn't Exist** -- **Status:** ✅ RESOLVED (reverted in `8455cbe`) -- **Fix:** Removed SSH multiplexing; plan needs redesign with `programs.ssh.extraConfig` - -### Outstanding Items (By Phase) - -From development report (lines 92–101): - -| Item | Status | Notes | -|------|--------|-------| -| Topology rectification | ✅ Complete | `real-topology/` eliminated | -| SSH multiplexing | ❌ Blocked | `matchBlocks` doesn't exist; redesign needed | -| GitHub runner module | ⬜ Pending | Phase 4, independent | -| LLM-CORE re-enable | ⬜ Pending | Phase 6, independent | -| Documentation update | ✅ Complete | AGENTS.md, file_structure.md, code_structure.md updated | - -### Recommendations from Development Report (Lines 102–108) - -1. **SSH multiplexing redesign** — Use `programs.ssh.extraConfig` with `Match` blocks (less ideal but functional) -2. **Deprecate `generate-golden`** — Remove or update to use `serialize-config.nix` -3. **Tag current state** — After merging `overlord-II-exec` into `overlord-II`, tag as `v1.10-topology-rectified` - -**Verdict:** ⚠️ **TWO BLOCKERS RESOLVED, ONE REMAINS BLOCKED** — SSH multiplexing redesign is deferred but not critical to fleet operation. - ---- - -## 9.

The branch has accumulated 19 commits since `db90b5d`, but most of that work was unplanned topology-rectification cleanup and documentation. The core Phase B (transformer architecture completion) and Phase C (library split preparation) goals remain **largely incomplete**. SSH multiplexing was attempted but reverted. LLM-CORE re-enable, GitHub runner custom module, and backup topology are untouched. - -**Overall Status:** ⚠️ **DEVIATION FROM PLAN — Significant gaps in Phase B/C core objectives** - ---- - -## Phase B Assessment: Complete Transformer Architecture - -### B.1: WIP Transformers — mkDnsSettings, mkFirewallSettings, mkNginxSettings - -#### mkDnsSettings.nix — ❌ NOT PRODUCTION-READY - -```nix -dhcpRange = "10.89.128.100,10.89.128.200,24h"; # WRONG SUBNET — topology uses 10.88.128.0/24 -upstreamServers = [ "8.8.8.8" "1.1.1.1" ]; # HARDCODED EXAMPLE DATA -dnsEntries = [ ]; # EMPTY — no real DNS data -dhcpHosts = [ ]; # EMPTY — no real DHCP hosts -``` - -**Problems:** -- The DHCP range uses `10.89.128.0/24` but the actual LAN subnet is `10.88.128.0/24` (per `topology/shared.nix` and `topology/cortex-alpha.nix`) -- No static DNS entries (`dnsEntries = [ ]`) -- No DHCP host reservations (`dhcpHosts = [ ]`) -- Returns only hardcoded placeholder data — this is a skeleton, not a working transformer -- Warnings and errors are empty arrays - -**Verdict:** This transformer cannot generate correct DNS/DHCP configuration. It must read real data from topology before it can be considered production-ready. - ---- - -#### mkFirewallSettings.nix — ❌ NOT PRODUCTION-READY - -```nix -tcpPorts = lib.unique ([ 22 1108 ] ++ - (if machine ? nginx-proxy then [ 443 ] ++ extractServicePorts machine.nginx-proxy else [ ]) ++ - (if machine ? firewall then machine.firewall.allowedTCPPorts or [ ] else [ ])); -``` - -**Problems:** -- Base ports `[ 22 1108 ]` are hardcoded — no data source -- `extractServicePorts` function attempts to parse `nginx-proxy` backends, but: - - It splits on `:` and assumes port is at index 1, which is fragile - - If `nginx-proxy` structure differs from expectations, returns null -- No integration with `topology/.nix` firewall data (the real firewall rules live in `topology/cortex-alpha.nix.firewall`) -- `firewall.allowedUDPPorts` only includes hub ports and explicit machine firewall rules — no WAN port forwarding data from `topology..forwarding` -- `interfaces` field generates empty `{ }` for machines with `lan` — this is incomplete - -**Verdict:** This transformer attempts to derive firewall settings from topology, but the actual firewall data in `topology/cortex-alpha.nix.firewall` is not being consumed. The logic is a first-pass sketch, not working code. - ---- - -#### mkNginxSettings.nix — ⚠️ PARTIALLY WORKING — HAS LOGIC FLAWS - -```nix -acmeHost = - if proxies != { } then - let - firstDomain = builtins.head (builtins.attrNames proxies); - parts = lib.splitString "." firstDomain; - in - builtins.concatStringsSep "."

But `topology/default.nix` only imports `cortex-alpha.nix` as a per-machine override — **no other machine has a detailed topology file**. - -This means: -1. `mkNginxSettings` expects `machine.nginx-proxy` — only cortex-alpha has this -2. `mkFirewallSettings` expects `machine.firewall` — only cortex-alpha has this -3. `mkDnsSettings` expects `machine.lan` with DHCP data — only cortex-alpha has this - -For all other machines, these transformers would return null or empty data. - -### Finding 3: Git History Shows Unplanned Work Dominated - -The 19 commits on `overlord-II` since `db90b5d` show a pattern of unplanned work consuming bandwidth: - -``` -0902092 docs: add overlord-II consolidated execution plan -511141b fix(prometheus): unlimited retention -4e7f989 docs: final deployment status and tool patterns -8691cc6 docs: overlord-II deployment status -ad9770c docs: overlord-II development report -8455cbe revert(ssh): remove matchBlocks -279ff55 docs: update documentation for new topology structure -0d79eea feat(ssh): implement fleet-wide SSH multiplexing -71c6f42 cleanup(topology): remove real-topology/ directory -eea67b8 refactor(topology): update all imports to new topology/ paths -4b967b0 feat(topology): create new directory structure -``` - -Only 3-4 commits (SSH multiplexing, topology rectification) are related to the planned goals. The rest are documentation, revert, or unrelated fixes. - -### Finding 4: The `core-router-topology.nix` is WIP Architecture in Limbo - -The AGENTS.md describes `core-router-topology.nix` as: -> "Hub machine module (WIP)" -> "Status: WIP — `enable-wg-topology.nix` is deployed on 13 client machines (replaces legacy `enable-wg.nix`). `core-router-topology.nix` is not yet wired into cortex-alpha." - -This confirms the assessment: the WIP architecture exists but is stranded — not deployed to any machine, cannot be validated, and is effectively dead code pending integration. - ---- - -## Risks and Blockers - -| Risk | Severity | Status | -|------|----------|--------| -| WIP transformers produce wrong output (wrong subnet, empty data) | HIGH | Unchanged — transformers not fixed | -| WIP architecture (core-router-topology) never gets validated | HIGH | Unchanged — not wired to any machine | -| Backup topology never started | MEDIUM | Unchanged | -| SSH multiplexing redesign not started | MEDIUM | Plan exists but approach needs revision | -| Library split (Phase C) not initiated | MEDIUM | No work detected | -| LLM-CORE remains disabled | MEDIUM | No re-enable work | -| GitHub runner Phase 2 not started | MEDIUM | Phase 1 override is fragile | -| Planned phases not tracked — work done ad-hoc | LOW | Deviation from prescribed methodology | - ---- - -## Recommendations - -1. **Phase B priority:** Wire `core-router-topology.nix` into cortex-alpha **one transformer at a time**, validating each against golden tests before proceeding. Start with `mkWireguardSettings` + `genWireguard` since they have the most complete logic. - -2. **Fix mkDnsSettings:** The DHCP range must use `10.88.128.0/24` not `10.89.128.0/24`. Replace all hardcoded values with real data from `topology/cortex-alpha.nix.dns`. - -3. **Fix mkNginxSettings ACME extraction:** The `lib.drop 1 parts` logic is fragile. Use `lib.removeSuffix` or pattern matching on the domain structure properly. - -4. **SSH multiplexing redesign:** Evaluate `programs.ssh.extraConfig` approach specified in the revert commit. Update the plan document with the new approach. - -5. **LLM-CORE:** If re-enable is still desired, uncomment the input and module imports in `flake.nix` and run the Phase 6 validation steps from the plan. - -6. **Library split:** Before attempting Phase C, the WIP architecture must be validated in production. The three-way split (Ketchup/Secret-Sauce/Mayo) requires a stable interface (the transformer output format) to base the extraction on. - ---- - -## Conclusion - -Overlord-II has made partial progress on infrastructure cleanup (topology rectification) but has **not completed the core Phase B or Phase C objectives**. The WIP transformer architecture exists but is not wired into any production machine, cannot be validated against golden tests, and produces incorrect output due to placeholder data. SSH multiplexing was attempted and reverted. The remaining goals (GitHub runner Phase 2, LLM-CORE, backup topology, library split) are planned but not started. - -The branch is in a **stabilization state** — infrastructure cleanup is complete, but the forward development goals remain in a early WIP stage. - ---- - -*Review conducted by tpol-minimax — 2026-07-12* diff --git a/documentation/2026-07-12-OVERLORD-II-REVIEW/tpol-xai-REVIEW-2026-07-12.md b/documentation/2026-07-12-OVERLORD-II-REVIEW/tpol-xai-REVIEW-2026-07-12.md deleted file mode 100644 index 178319c8..00000000 --- a/documentation/2026-07-12-OVERLORD-II-REVIEW/tpol-xai-REVIEW-2026-07-12.md +++ /dev/null @@ -1,351 +0,0 @@ -# OVERLORD-II Structural Review — tpol-xai -**Date:** 2026-07-12 -**Reviewer:** tpol-xai (structural analysis specialist) -**Focus:** Topology architecture, import graph, dead code, structural integrity -**Branch:** overlord-II (0902092) -**Constraint:** Read-only analysis — no code changes, no SSH access - ---- - -## Executive Summary - -The overlord-II topology rectification successfully migrated from `real-topology/` to `topology/` + `goldens/`.

Needs modification. - -### Vector 2: Detect dead master before consuming "started" - -After spawning the command SSH, check if the master socket is still alive. If dead, consume "started". If alive, skip. - -**Implementation:** Call `isMasterRunning()` after `startProcess()` but before the `readLine()` conditional. If the master died between `startMaster()` and `startCommand()`, the fallback has occurred. - -**Risk:** Race condition — the master might die between the check and the read. Also, `isMasterRunning()` runs `ssh -O check` which has overhead. - -### Vector 3: Set `ControlPersist=15m` on the master SSH - -Add `-oControlPersist=15m` to the master SSH args in `startMaster()`. This keeps the master alive for 15 minutes after the last command disconnects. - -**Implementation:** In `startMaster()`, after building the args list, add: -```cpp -args.push_back(OS_STR("-oControlPersist=15m")); -``` - -**Risk:** Doesn't fix the underlying bug — just makes it much less likely to trigger. If the master dies for other reasons (network interruption, OOM kill), the issue persists. - -### Vector 4: Use `-oLocalCommand=true` on command SSHs (no-op) - -Override `LocalCommand` on command SSHs to a no-op command. This prevents `"started"` from appearing on the command SSH's stdout even if it falls back to a direct connection. - -**Implementation:** In `startCommand()`, when `useMaster=true`, add `-oLocalCommand=true` to the command SSH args (after `addCommonSSHOpts` which adds `-oLocalCommand=echo started`). The later `-oLocalCommand=true` overrides the earlier one. - -**Risk:** If the command SSH falls back to a direct connection, the no-op `LocalCommand` means `startCommand()` doesn't need to consume anything. But `startCommand()` still skips the read (because `useMaster=true`), so the protocol handler reads the nix-daemon protocol directly. This should work. - -### Vector 5: Use a separate file descriptor for "started" signal - -Replace `LocalCommand=echo started` with a mechanism that writes to a file descriptor or named pipe, not stdout. `startCommand()` reads from the file descriptor instead of stdout. - -**Implementation:** Use `-oLocalCommand="echo started >&3"` and pass fd 3 through the SSH process. `startCommand()` reads from fd 3 instead of stdout. - -**Risk:** Complex. SSH might not pass arbitrary file descriptors. Requires changes to both `startMaster()` and `startCommand()`. - -### Vector 6: Use `-F /dev/null` on all Nix SSH invocations - -Force SSH to ignore the system config by passing `-F /dev/null`. This prevents any OS-level `ControlMaster` or `LocalCommand` settings from interfering. - -**Implementation:** In `addCommonSSHOpts()`, add: -```cpp -args.push_back(OS_STR("-F")); -args.push_back(OS_STR("/dev/null")); -``` - -**Risk:** This prevents Nix from using any SSH config settings (like `UserKnownHostsFile`, `IdentityFile`, etc.). Nix already passes these via command-line options, so it should work. But it's a heavy-handed approach. - -### Vector 7: Set `max-connections=1` for `ssh-ng` in `machines.cc` - -Match the `ssh` protocol behavior: -```cpp -if (generic && (generic->scheme == "ssh" || generic->scheme == "ssh-ng")) { - storeUri.params["max-connections"] = "1"; -} -``` - -**Risk:** Limits `ssh-ng` to a single connection.

Pool creates new connection: `startMaster()` sees master PID exists (state->sshMaster != INVALID_DESCRIPTOR) → **fast-path returns socketPath without checking `isMasterRunning`** -4. `startCommand()` checks `isMasterRunning()` → master still alive (race timing) -5.

Nix doesn't use host aliases — it resolves hostnames directly. Safe. -- ⚠️ `ProxyJump` / `ProxyCommand` configured in `~/.ssh/config` would be ignored. Users relying on this would need to set `NIX_SSHOPTS` or `extraSshArgs` instead. -- ⚠️ `IdentityFile` configured in `~/.ssh/config` without `-i` would be ignored. Nix already passes `-i`. Safe. -- ⚠️ `UserKnownHostsFile` custom paths would be ignored. Nix already passes its own. Safe. -- ⚠️ `ControlMaster`, `ControlPath`, `ControlPersist` from SSH config would be ignored. Nix sets these explicitly. Safe. -- ⚠️ `SendEnv`, `SetEnv`, `AcceptEnv` — Nix doesn't rely on these. Safe. -- ⚠️ `StrictHostKeyChecking` — Nix doesn't explicitly set this. But it uses `UserKnownHostsFile` to provide its own known hosts. The system default for `StrictHostKeyChecking` is usually `ask`, which might cause issues if not set to `accept-new` or similar. However, `-F /dev/null` would use OpenSSH's compiled-in defaults, which is `StrictHostKeyChecking=ask`. This could cause interactive prompts — a problem if the host key file doesn't contain the host! - -Wait, this is a real issue. With `-F /dev/null`, OpenSSH uses its internal defaults: -- `StrictHostKeyChecking=ask` by default -- Nix's custom `UserKnownHostsFile` is set via `-o`, so that's used -- But `StrictHostKeyChecking` controls behavior when the host key is NOT found in the known hosts file - -If Nix's custom known hosts file is present and has the host key, `StrictHostKeyChecking` doesn't matter (the key is found and verified). But if the key is missing (e.g., first connection), SSH would prompt the user, which would hang Nix. - -However, looking at the code, `sshPublicHostKey` is explicitly set per-machine. If it's empty, `-oUserKnownHostsFile` is NOT added. So for first connections without a known host key, the system default `~/.ssh/known_hosts` would be used. With `-F /dev/null`, we'd lose access to that. - -**Conclusion:** `-F /dev/null` is risky without also explicitly setting `StrictHostKeyChecking`. - -### 5.4 Verdict: **HIGH RISK, NOT RECOMMENDED** - -| Criterion | Rating | -|---|---| -| Technical soundness | ❌ Requires companion fix for StrictHostKeyChecking | -| Regression risk | ❌ High — breaks SSH config for ProxyJump, custom IdentityFile, etc. | -| Upstreamability | ❌ Too heavy-handed | -| Alternatives | ✅ Vector 4 + Vector 3 is more targeted | - ---- - -## 6. Other Vectors — Evaluation - -### Vector 1: Always Consume "started" - -Already analyzed in the review. **Broken** — a live multiplex doesn't produce "started", so `readLine()` would block reading the first byte of the worker protocol, which would not equal "started", causing a spurious error. - -### Vector 5: Separate File Descriptor - -Using `-oLocalCommand="echo started >&3"` and passing fd 3 through the SSH process: -- **Problem:** `startProcess()` doesn't provide an easy way to pass an extra fd to the child -- **Problem:** Complexity is high — need to create a pipe, pass fd 3 through `dup2`, coordinate between parent and child -- **Problem:** Not portable (Windows, different shells) -- **Verdict:** Technically interesting but over-engineered - -### Vector 7: `max-connections=1` for `ssh-ng` - -**Defeats the purpose** of the Determinate Nix performance improvement.

Proposed Implementation: Vector 4 (Primary) + Vector 3 (Secondary) - -### 8.1 Why Vector 4 Is the Best Choice - -Vector 4 (`-oLocalCommand=true`) is the **only vector that eliminates the information leak at the source**. It works because: - -1. **Producer-side fix**: Override `LocalCommand` on command SSHs to a no-op -2. **No dependency on timing**: Not a point-in-time check, not a race window reduction -3. **No behavioral change for live masters**: Through a live multiplex, LocalCommand doesn't fire anyway -4. **Minimal diff**: One line change in `startCommand()` -5. **SSH option semantics**: Last `-o` wins — deterministic, well-documented - -### 8.2 Pseudocode - -**File:** `src/libstore/ssh.cc` - -```cpp -// In SSHMaster::startCommand(), around line 190, -// AFTER addCommonSSHOpts(args, socketPath) and BEFORE extraSshArgs: - -if (!fakeSSH) { - args = {"ssh", hostnameAndUser.c_str(), "-x"}; - addCommonSSHOpts(args, socketPath); - if (verbosity >= lvlChatty) - args.push_back("-v"); - - // === PROPOSED FIX === - // Override LocalCommand to no-op on command SSH invocations. - // When useMaster=true, addCommonSSHOpts() sets - // -oLocalCommand=echo started.

If "started" will never be produced, don't try to read it. - -**Revised pseudocode:** - -```cpp -// current line 211: -if (!fakeSSH && !(socketPath && isMasterRunning(*socketPath))) { - std::string reply; - try { - reply = readLine(out.readSide.get()); - } catch (EndOfFile & e) { - } - if (reply != "started") { - printTalkative("SSH stdout first line: %s", reply); - throw Error("failed to start SSH connection to '%s'", authority.host); - } -} -``` - -**Revised:** - -```cpp -if (!fakeSSH && !useMaster && !(socketPath && isMasterRunning(*socketPath))) { - // When useMaster=true, LocalCommand is overridden to true (no-op), - // so no "started" is produced even on fallback direct connections. - // Non-master mode (useMaster=false) still uses LocalCommand=echo started. - std::string reply; - try { - reply = readLine(out.readSide.get()); - } catch (EndOfFile & e) { - } - if (reply != "started") { - printTalkative("SSH stdout first line: %s", reply); - throw Error("failed to start SSH connection to '%s'", authority.host); - } -} -``` - -Wait, but this means `useMaster=true` with a dead master would never read "started" — and it shouldn't need to, because `-oLocalCommand=true` prevents the output. But we lose the error detection: if the command SSH connection fails entirely (not a fallback but a real failure), we won't detect it because we don't read anything. - -Hmm, this is a trade-off. The existing error detection is: -```cpp -if (reply != "started") { - throw Error("failed to start SSH connection to '%s'", authority.host); -} -``` - -With Vector 4 and `useMaster=true`, we lose this error detection. The command SSH could fail silently, and the nix protocol would hang or get garbage. - -**Better approach:** Keep the conditional read but don't require "started": - -```cpp -if (!fakeSSH && !(socketPath && isMasterRunning(*socketPath))) { - if (!useMaster) { - // Non-master mode: LocalCommand=echo started produces "started" - std::string reply; - try { - reply = readLine(out.readSide.get()); - } catch (EndOfFile & e) { - } - if (reply != "started") { - printTalkative("SSH stdout first line: %s", reply); - throw Error("failed to start SSH connection to '%s'", authority.host); - } - } else { - // Master mode: LocalCommand overridden to true (no-op). - // No "started" to consume.

We could read the first - // byte and check if it's valid worker protocol magic. - // For now, skip — the connection will be validated by - // initConnection() which reads worker protocol handshake. - } -} -``` - -But this is getting more complex. A simpler approach: **just skip the read when useMaster=true and master is dead**. The connection will be validated by `initConnection()` anyway. If the connection failed, the read in `initConnection()` will get EOF or garbage. - -Actually, even simpler: **treat `useMaster=true` the same as `useMaster=false` for the master-dead case, but without expecting "started"**: - -```cpp -if (!fakeSSH && !(socketPath && isMasterRunning(*socketPath))) { - if (useMaster) { - // LocalCommand overridden to true — no "started" to consume. - // But we still need to wait briefly for the connection to - // establish before the progress bar overwrites output. - // A simple sleep(1) is too crude; instead use select/poll - // with a timeout to wait for data or error on the fd. - try { - // Wait up to 500ms for data to appear - struct pollfd pfd = { out.readSide.get(), POLLIN, 0 }; - poll(&pfd, 1, 500); - } catch (...) { } - } else { - std::string reply; - try { - reply = readLine(out.readSide.get()); - } catch (EndOfFile & e) { } - if (reply != "started") { - printTalkative("SSH stdout first line: %s", reply); - throw Error("..."); - } - } -} -``` - -Hmm, this is getting complex. Let me re-read the comment in the code about what the conditional read is FOR: - -```cpp -// Wait for the SSH connection to be established, -// So that we don't overwrite the password prompt with our progress bar. -``` - -So the purpose is to prevent the progress bar from overwriting the SSH password prompt. It's NOT primarily for error detection — the "started" check IS the error detection. The comment says the purpose is **waiting for the connection to be established**. - -With `useMaster=true`: -- If the multiplex connection works, there's no password prompt (already authenticated) -- If the fallback connection is direct, there COULD be a password prompt -- We still need to wait for the connection - -So the real question is: **do we need to wait for connection establishment when useMaster=true and master is dead?** - -Answer: Yes, we still want to wait, because if the user hasn't set up key-based auth, SSH would prompt for a password. But the progress bar suspension is only done for `!useMaster`: - -```cpp -if (!fakeSSH && !useMaster) { - loggerSuspension = std::make_unique(logger->suspend()); -} -``` - -When `useMaster=true`, the logger is not suspended. So there's no progress bar to overwrite the password prompt. **The wait is not needed when `useMaster=true`.** We can simply skip the entire conditional block: - -```cpp -if (!fakeSSH && !useMaster && !(socketPath && isMasterRunning(*socketPath))) { - // ... read "started" ... -} -``` - -This is the cleanest approach. Add `!useMaster` to the condition.

Edge Case Analysis - -### 9.1 NIX_SSHOPTS Contains `-oLocalCommand` - -If a user sets `NIX_SSHOPTS="-oLocalCommand=something"`, this takes effect BEFORE the hard-coded `-oLocalCommand=echo started` in `addCommonSSHOpts()`. The hard-coded one wins (last). Our `-oLocalCommand=true` wins over both (even later). User's custom LocalCommand is effectively overridden when `useMaster=true`. This is correct behavior — we don't want custom LocalCommand to produce output on the protocol stream. - -### 9.2 `extraSshArgs` Contains `-oLocalCommand` - -Similarly, if a user passes `-oLocalCommand=something` via `extraSshArgs`, our `-oLocalCommand=true` would need to come AFTER `extraSshArgs`. Looking at the code: - -```cpp -args.splice(args.end(), std::move(extraSshArgs)); -args.push_back("--"); -``` - -Our override is BEFORE `extraSshArgs`. So `extraSshArgs` containing `-oLocalCommand=something` would override our `true`. **Fix:** move the override after `extraSshArgs`: - -```cpp -args.splice(args.end(), std::move(extraSshArgs)); -if (useMaster) args.push_back(OS_STR("-oLocalCommand=true")); -args.push_back("--"); -``` - -Wait, but `extraSshArgs` is a user-controlled parameter. If they explicitly set a LocalCommand, they probably have a reason. But overriding it is the safe choice for protocol integrity. Let's keep it last. - -### 9.3 `runProgram` in `isMasterRunning()` — Output Leak - -`isMasterRunning()` uses `runProgram()` with `mergeStderrToStdout = true` and captures both stdout and stderr. It ignores the output and only checks the exit code. Even if LocalCommand fires on the `-O check` process, the output is discarded. No leak here. - -### 9.4 The `fakeSSH` Case - -When `authority.to_string() == "localhost"`, `fakeSSH` is true. The SSH commands run locally via `exec` of the command directly (no SSH). The stdout of the local process is the nix daemon protocol. No "started" issue. - -### 9.5 Windows - -The code under `#ifdef _WIN32` throws `UnimplementedError`. No analysis needed. - ---- - -## 10. Answer Summary - -| Question | Answer | -|---|---| -| **1. Trace the exact data flow** | `startMaster()` → creates master SSH with stdout pipe → reads "started" from master. `startCommand()` → creates command SSH with stdout pipe → if master dead/absent, reads "started" from command. `initConnection()` → reads worker protocol from command SSH's stdout (after consumed "started"). **Bug:** TOCTOU race causes "started" to not be consumed. | -| **2. Vector 4 (no-op LocalCommand)** | ✅ **Works.** `-oLocalCommand=true` after `-oLocalCommand=echo started` overrides per SSH's last-wins semantics. Combined with `!useMaster` guard on the read, eliminates the leak entirely. | -| **3. Vector 2 (detect dead master)** | ❌ **Inherently racy.** `isMasterRunning()` is a point-in-time check that cannot eliminate the TOCTOU window between check and connection. | -| **4. Vector 3 (ControlPersist)** | ⚠️ **Mitigation, not fix.** Reduces race frequency but doesn't eliminate it. Best as secondary defense alongside Vector 4. Add at line 265 in `startMaster()`. | -| **5. Vector 6 (-F /dev/null)** | ❌ **High risk.** Would break SSH config-based ProxyJump, custom IdentityFile, and StrictHostKeyChecking behavior. Not recommended. | -| **6. Proposed implementation** | **Vector 4 primary + Vector 3 secondary.** One-line change in `startCommand()` to add `-oLocalCommand=true` when `useMaster=true`. Optionally change `ControlPersist=no` to `ControlPersist=15m` in `startMaster()`. Upstreamable, minimal diff, no regressions. | - ---- - -## 11. Upstream Recommendation - -**Submit Vector 4 as the primary fix** to both NixOS/nix and DeterminateSystems/nix-src: - -1. **Two-line diff** in `ssh.cc`: - - Add `if (useMaster) args.push_back(OS_STR("-oLocalCommand=true"));` after `addCommonSSHOpts()` in `startCommand()` and after `extraSshArgs` splice - - This prevents "started" from ever appearing on command SSH stdout, regardless of connection path - -2. **Rationale for upstream**: The fix is defensive programming — it ensures that command SSH invocations never produce protocol-corrupting output regardless of connection fallback behavior. It's not specific to Determinate's `maxConnections=64` change; it makes the SSH master mode robust for any configuration. - -3. **Testing**: - - Unit: Verify SSH args ordering produces correct final `LocalCommand` - - Integration: Test with `ControlPersist=no` (default) under concurrent connection load - - Integration: Test with manual master kill to trigger fallback diff --git a/documentation/2026-07-15-DETSYS-NIX-SSH-MASTER-FIX-REVIEW/tpol-minimax-REVIEW-2026-07-15.md b/documentation/2026-07-15-DETSYS-NIX-SSH-MASTER-FIX-REVIEW/tpol-minimax-REVIEW-2026-07-15.md deleted file mode 100644 index 372601d0..00000000 --- a/documentation/2026-07-15-DETSYS-NIX-SSH-MASTER-FIX-REVIEW/tpol-minimax-REVIEW-2026-07-15.md +++ /dev/null @@ -1,498 +0,0 @@ -# TPol-Minimax Research Review: DETSYS-NIX SSH Master Protocol Leak Fix - -**Date:** 2026-07-15 -**Reviewer:** tpol-minimax -**Subject:** Nix SSH Master mechanism and protocol leak bug via `LocalCommand=echo started` - ---- - -## Executive Summary - -Determinate Nix changed `maxConnections` default from 1 to 64 in `remote-store.hh`, enabling SSH master mode (`-M -N`) for `ssh-ng` remote builders.
