Specification Document\n  2 \n  3 ## Project Overview\n  4 **Title:** Linux_Patch_API  \n  5 **Description:** API service for secure remote management of patching processes and software add/removal  \n  6 **Version:** 0.0.1  \n  7 **Status:** Draft  \n  8 \n  9 ## Scope\n 10 \n 11 **Primary Focus:** Debian/Ubuntu (apt/dpkg)  \n 12 **Secondary Support:** RHEL/CentOS/Fedora (dnf/yum), Alpine (apk), Arch (pacman)  \n 13 \n 14 **In Scope:**\n 15 - Remote package installation, removal, and updates\n 16 - System patch management (security and general updates)\n 17 - Multi-distribution support via pluggable package manager backend\n 18 - Secure authentication and authorization for remote operations\n 19 - Audit logging of all package/patch operations\n 20 - RESTful API design with JSON request/response\n 21 \n 22 **Supported Operations:**\n 23 - **Core Package:** GET /packages (with filtering), GET /packages/{name}, POST /packages (install), PUT /packages/{name} (update), DELETE /packages/{name} (remove)\n 24 - **Patch Management:** GET /patches (list available), POST /patches/apply (apply all or specific)\n 25 - **System Info:** GET /system/info (OS version, kernel, last update time)\n 26 \n 27 **Operation Features:**\n 28 - Version pinning support (e.g., package=1.2.3)\n 29 - Rollback capability for failed operations\n 30 - Batch operations: best-effort (not atomic)\n 31 - GET filtering: by name, version, status, upgradable\n 32 - No pagination (return all results)\n 33 \n 34 **Out of Scope (for now):**\n 35 - GUI/frontend interface (API-only)\n 36 - Automatic scheduled patching (manual trigger only)\n 37 - Cross-distribution package compatibility\n 38 \n 39 ## Objectives\n 40 \n 41 **Primary Objective:** Provide secure API for remote patch/package management on individual Linux hosts\n 42 \n 43 **Key Goals:**\n 44 - Run as a system service on each managed machine (Option B: Agent Per Host)\n 45   - systemd for Debian/Ubuntu, RHEL/CentOS/Fedora\n 46   - OpenRC for Alpine Linux\n 47 - Internal network access only (no internet exposure)\n 48 - Support Debian/Ubuntu first, then expand to other distributions\n 49 - Maintain audit trail of all operations\n 50 - Minimal resource footprint\n 51 - mTLS certificate-based authentication\n 52 - IP whitelist enforcement (deny by default)\n 53 \n 54 ## Constraints\n 55 \n 56 **Deployment:**\n 57 - One API instance per host\n 58 - Internal network only (LAN/private network)\n 59 - No public internet exposure\n 60 - Must run as a system service (init system determined by distribution)\n 61   - systemd: Debian, Ubuntu, RHEL, CentOS, Fedora\n 62   - OpenRC: Alpine Linux\n 63 \n 64 **Technical:**\n 65 - Must run with elevated privileges for package management (root/sudo)\n 66 - Must support multiple Linux distributions\n 67 - API-only (no GUI required)\n 68 - mTLS required for all client connections\n 69 - IP whitelist enforcement required (block all by default, allow only listed)\n 70 - Technology: Rust with Actix-web or Axum framework\n 71 - Default API port: 12443\n 72 - API Style: Pure REST (resources as nouns, HTTP verbs for actions)\n 73 - Data Format: JSON for all requests and responses\n 74 - Response Envelope: Standard envelope with success, request_id, timestamp, data, error fields\n 75 - Request IDs: Required for all requests (tracking and auditing)\n 76 - Execution Model: Hybrid (sync for quick ops, async with job ID for long ops)\n 77 - Real-time Updates: WebSocket support for job status streaming\n 78 - Job Timeout: Maximum 30 minutes per operation\n 79 \n 80 **Security:**\n 81 - Certificate-based authentication (mTLS)\n 82 - Network-level access control via IP/subnet whitelist\n 83 - Silent drop for non-mTLS connections (no response)\n 84 - Detailed error messages for authenticated clients only\n 85 \n 86 ## Error Handling\n 87 \n 88 - **HTTP Status Codes:** Standard HTTP status codes (200, 400, 401, 403, 404, 500, etc.)\n 89 \n 90 - **Error Response Format** (inside envelope's `error` field):\n 91 ```json\n 92 {\n 93   \"code\": \"ERROR_CODE\",\n 94   \"message\": \"Human-readable description\",\n 95   \"details\": {},\n 96   \"retryable\": false\n 97 }\n 98 ```\n 99 \n100 - **Error Categories:**\n101   - Authentication failures (invalid/expired cert)\n102   - Authorization failures (valid cert but not whitelisted IP)\n103   - Package not found\n104   - Package manager errors (dpkg/apt failures)\n105   - Permission denied\n106   - System resource errors\n107   - Configuration errors\n108 \n109 - **Error Message Policy:**\n110   - mTLS confirmed clients: Detailed error messages with debugging info\n111   - Non-mTLS connections: Silent drop (no response sent)\n112   - DEBUG mode: Include additional diagnostic information\n113 \n114 - **Idempotency:** Operations should be idempotent where possible (safe to retry)\n115 \n116 ## Assumptions\n117 \n118 - Host machines have network connectivity to internal clients\n119 - API clients are trusted internal systems\n120 - Host OS has Rust toolchain available (or can be installed)\n121 - Package manager (apt/dnf/apk/pacman) is functional on target hosts\n122 \n123 ## Dependencies\n124 \n125 - Linux OS with package manager support\n126 - Init system for service management (distribution-dependent)\n127   - systemd (most distributions)\n128   - OpenRC (Alpine Linux)\n129 - Network access for API communication\n130 - mTLS certificate infrastructure (CA, client certs)\n131 - IP whitelist configuration\n132 - Rust toolchain (rustc, cargo)\n133 - Actix-web or Axum framework\n134 - Internal CA for certificate issuance (self-hosted)\n135 \n136 ## Certificate Management\n137 \n138 - **CA Type:** Internal self-hosted Certificate Authority\n139 - **Distribution:** Manual certificate distribution OR automated Self-Enrollment\n140 - **Scope:** Limited distribution (small number of authorized clients)\n141 - **Validity Period:** 1 year standard expiration\n142 - **Client Identity:** Unique certificate per client (no shared certs)\n143 - **Rotation:** Manual renewal process before expiration\n144 \n145 ## Self-Enrollment Workflow\n146 \n147 The `linux_patch_api` daemon supports an automated self-enrollment workflow to securely request identity from the `linux_patch_manager` without manual PKI distribution.\n148 \n149 - **Trigger:** Initiated via CLI flag during setup/first run (e.g., `linux_patch_api --enroll https://<manager_url>`).\n150 - **Phase 1: Registration Request:**\n151   - Extracts `/etc/machine-id`, FQDN, IP Address, and OS details.\n152   - Submits an unauthenticated `POST /api/v1/enroll` request to the manager.\n153   - Receives a temporary `polling_token`.\n154 - **Phase 2: Polling & Approval:**\n155   - The daemon enters a polling loop, querying `GET /api/v1/enroll/status/{token}` (e.g., every 60 seconds).\n156   - Aborts if HTTP 403 or 404 is returned (request denied/purged).\n157 - **Phase 3: Provisioning:**\n158   - Upon HTTP 200, extracts the provided PKI bundle (`ca.crt`, `server.crt`, `server.key`).\n159   - Writes certificates to the configured mTLS storage paths.\n160   - Automatically appends the manager's IP address to `/etc/linux_patch_api/whitelist.yaml`.\n161   - Transitions to standard mTLS listening mode without requiring a service restart.\n162 \n163 ## Audit Logging\n164 \n165 - **Log Content (All Required):**\n166   - Every API request (endpoint, method, timestamp, client cert ID)\n167   - Package operations (package name, version, action: install/remove/update)\n168   - Authentication events (success/failure, cert validation)\n169   - IP whitelist denials (blocked connection attempts)\n170   - System changes made by the API\n171   - Configuration changes (whitelist updates, cert renewals)\n172 \n173 - **Log Storage:**\n174   - Primary: Distribution-appropriate logging\n175     - systemd journal (journalctl) on systemd systems\n176     - syslog/local files on OpenRC systems\n177   - Secondary: Optional remote syslog server (universal)\n178   - Local file logs as fallback (`/var/log/linux_patch_api/`)\n179 \n180 - **Log Retention:**\n181   - Retention period: 30 days\n182   - Rotation: Daily\n183   - Compression: Enabled (gzip)\n184 \n185 - **Log Levels:** Configurable at runtime (DEBUG, INFO, WARN, ERROR)\n186 \n187 ## IP Whitelist Configuration\n188 \n189 - **Config File:** `/etc/linux_patch_api/whitelist.yaml`\n190 - **Format:** YAML\n191 - **Management:** Static config file (edit file to change)\n192 - **Apply Method:** Instant apply on file change (no restart required)\n193 - **Logging:** All whitelist changes logged to audit log\n194 \n195 - **Supported Entries:**\n196   - Individual IPv4 addresses (e.g., `192.168.1.100`)\n197   - CIDR subnets (e.g., `192.168.1.0/24`)\n198   - Hostnames (resolved at config load)\n199   - IPv6: Not supported (explicitly out of scope)\n200 \n<<<", "kvps": {"action": "read", "path": "/a0/usr/projects/linux_patch_api/SPEC.md", "_tool_name": "text_editor"}, "timestamp": 1778976114}, {"type": "tool", "heading": "icon://construction A1: Using tool 'text_editor'", "content": "/a0/usr/projects/linux_patch_api/src/enroll/mod.rs 77 lines\n>>>\n 1 //!

Specification Document\n  2 \n  3 ## Project Overview\n  4 **Title:** Linux_Patch_API  \n  5 **Description:** API service for secure remote management of patching processes and software add/removal  \n  6 **Version:** 0.0.1  \n  7 **Status:** Draft  \n  8 \n  9 ## Scope\n 10 \n 11 **Primary Focus:** Debian/Ubuntu (apt/dpkg)  \n 12 **Secondary Support:** RHEL/CentOS/Fedora (dnf/yum), Alpine (apk), Arch (pacman)  \n 13 \n 14 **In Scope:**\n 15 - Remote package installation, removal, and updates\n 16 - System patch management (security and general updates)\n 17 - Multi-distribution support via pluggable package manager backend\n 18 - Secure authentication and authorization for remote operations\n 19 - Audit logging of all package/patch operations\n 20 - RESTful API design with JSON request/response\n 21 \n 22 **Supported Operations:**\n 23 - **Core Package:** GET /packages (with filtering), GET /packages/{name}, POST /packages (install), PUT /packages/{name} (update), DELETE /packages/{name} (remove)\n 24 - **Patch Management:** GET /patches (list available), POST /patches/apply (apply all or specific)\n 25 - **System Info:** GET /system/info (OS version, kernel, last update time)\n 26 \n 27 **Operation Features:**\n 28 - Version pinning support (e.g., package=1.2.3)\n 29 - Rollback capability for failed operations\n 30 - Batch operations: best-effort (not atomic)\n 31 - GET filtering: by name, version, status, upgradable\n 32 - No pagination (return all results)\n 33 \n 34 **Out of Scope (for now):**\n 35 - GUI/frontend interface (API-only)\n 36 - Automatic scheduled patching (manual trigger only)\n 37 - Cross-distribution package compatibility\n 38 \n 39 ## Objectives\n 40 \n 41 **Primary Objective:** Provide secure API for remote patch/package management on individual Linux hosts\n 42 \n 43 **Key Goals:**\n 44 - Run as a system service on each managed machine (Option B: Agent Per Host)\n 45   - systemd for Debian/Ubuntu, RHEL/CentOS/Fedora\n 46   - OpenRC for Alpine Linux\n 47 - Internal network access only (no internet exposure)\n 48 - Support Debian/Ubuntu first, then expand to other distributions\n 49 - Maintain audit trail of all operations\n 50 - Minimal resource footprint\n 51 - mTLS certificate-based authentication\n 52 - IP whitelist enforcement (deny by default)\n 53 \n 54 ## Constraints\n 55 \n 56 **Deployment:**\n 57 - One API instance per host\n 58 - Internal network only (LAN/private network)\n 59 - No public internet exposure\n 60 - Must run as a system service (init system determined by distribution)\n 61   - systemd: Debian, Ubuntu, RHEL, CentOS, Fedora\n 62   - OpenRC: Alpine Linux\n 63 \n 64 **Technical:**\n 65 - Must run with elevated privileges for package management (root/sudo)\n 66 - Must support multiple Linux distributions\n 67 - API-only (no GUI required)\n 68 - mTLS required for all client connections\n 69 - IP whitelist enforcement required (block all by default, allow only listed)\n 70 - Technology: Rust with Actix-web or Axum framework\n 71 - Default API port: 12443\n 72 - API Style: Pure REST (resources as nouns, HTTP verbs for actions)\n 73 - Data Format: JSON for all requests and responses\n 74 - Response Envelope: Standard envelope with success, request_id, timestamp, data, error fields\n 75 - Request IDs: Required for all requests (tracking and auditing)\n 76 - Execution Model: Hybrid (sync for quick ops, async with job ID for long ops)\n 77 - Real-time Updates: WebSocket support for job status streaming\n 78 - Job Timeout: Maximum 30 minutes per operation\n 79 \n 80 **Security:**\n 81 - Certificate-based authentication (mTLS)\n 82 - Network-level access control via IP/subnet whitelist\n 83 - Silent drop for non-mTLS connections (no response)\n 84 - Detailed error messages for authenticated clients only\n 85 \n 86 ## Error Handling\n 87 \n 88 - **HTTP Status Codes:** Standard HTTP status codes (200, 400, 401, 403, 404, 500, etc.)\n 89 \n 90 - **Error Response Format** (inside envelope's `error` field):\n 91 ```json\n 92 {\n 93   \"code\": \"ERROR_CODE\",\n 94   \"message\": \"Human-readable description\",\n 95   \"details\": {},\n 96   \"retryable\": false\n 97 }\n 98 ```\n 99 \n100 - **Error Categories:**\n101   - Authentication failures (invalid/expired cert)\n102   - Authorization failures (valid cert but not whitelisted IP)\n103   - Package not found\n104   - Package manager errors (dpkg/apt failures)\n105   - Permission denied\n106   - System resource errors\n107   - Configuration errors\n108   - Enrollment failures:\n109     - `ENROLLMENT_DENIED`: Admin rejected enrollment request on linux_patch_manager\n110     - `ENROLLMENT_EXPIRED`: Polling token expired or purged (HTTP 404 from manager)\n111     - `ENROLLMENT_TIMEOUT`: 24-hour polling limit exceeded (1440 attempts exhausted)\n112     - `ENROLLMENT_RATE_LIMITED`: Request rate limit exceeded (1/minute per IP, HTTP 429)\n113     - `PKI_PROVISION_FAILED`: Certificate write or PEM validation failed during provisioning\n114 \n115 - **Error Message Policy:**\n116   - mTLS confirmed clients: Detailed error messages with debugging info\n117   - Non-mTLS connections: Silent drop (no response sent)\n118   - DEBUG mode: Include additional diagnostic information\n119 \n120 - **Idempotency:** Operations should be idempotent where possible (safe to retry)\n121 \n122 ## Assumptions\n123 \n124 - Host machines have network connectivity to internal clients\n125 - API clients are trusted internal systems\n126 - Host OS has Rust toolchain available (or can be installed)\n127 - Package manager (apt/dnf/apk/pacman) is functional on target hosts\n128 \n129 ## Dependencies\n130 \n131 - Linux OS with package manager support\n132 - Init system for service management (distribution-dependent)\n133   - systemd (most distributions)\n134   - OpenRC (Alpine Linux)\n135 - Network access for API communication\n136 - mTLS certificate infrastructure (CA, client certs)\n137 - IP whitelist configuration\n138 - Rust toolchain (rustc, cargo)\n139 - Actix-web or Axum framework\n140 - Internal CA for certificate issuance (self-hosted)\n141 \n142 ## Certificate Management\n143 \n144 - **CA Type:** Internal self-hosted Certificate Authority\n145 - **Distribution:** Manual certificate distribution OR automated Self-Enrollment\n146   - Self-Enrollment provides automatic PKI provisioning after admin approval on linux_patch_manager\n147   - Eliminates manual certificate copy/permission management for new hosts\n148 - **Scope:** Limited distribution (small number of authorized clients)\n149 - **Validity Period:** 1 year standard expiration\n150 - **Client Identity:** Unique certificate per client (no shared certs)\n<<<", "kvps": {"action": "read", "path": "/a0/usr/projects/linux_patch_api/SPEC.md", "line_from": 1, "line_to": 150, "_tool_name": "text_editor"}, "timestamp": 1778976523}]

Configurable via `--poll-interval` flag |\n| 5 | Host receives PKI bundle on approval | Complete CA chain, server certificate, and private key in PEM format |\n| 6 | Host provisions mTLS infrastructure | Writes certificates to configured paths, updates IP whitelist, transitions to authenticated mode |\n\n---\n\n### Rate Limiting\n\n| Endpoint | Limit | Window | Scope |\n|----------|-------|--------|-------|\n| `POST /api/v1/enroll` | 1 request | Per minute | Per source IP address |\n| `GET /api/v1/enroll/status/{token}` | No explicit limit | \u2014 | Host-controlled polling interval |\n\n**Rate Limit Enforcement:**\n- POST `/enroll`: Enforced by manager using in-memory LRU cache keyed on source IP (or `X-Forwarded-For` first entry when behind reverse proxy)\n- Status endpoint: No server-side rate limiting; client controls poll frequency (default: 60s interval)\n\n---\n\n### Security Notes\n\n| Concern | Mitigation |\n|---------|------------|\n| **Initial connection security** | TLS verification disabled on enrollment client (`danger_accept_invalid_certs`).

Never log the raw token value (only hash stored in DB). Tokens expire after 24 hours by default |\n| **Host identity** | `machine_id` from `/etc/machine-id` provides unique host identification. Combined with FQDN and IP for collision detection during admin approval |\n| **FQDN/IP collision** | Admin approval checks existing hosts table \u2014 rejects enrollment if FQDN or IP already registered to another host (HTTP 409 Conflict) |\n| **Certificate isolation** | Each approved host receives a unique client certificate signed by internal CA.

Configurable via `--poll-interval` flag |\n1098 | 5 | Host receives PKI bundle on approval | Complete CA chain, server certificate, and private key in PEM format |\n1099 | 6 | Host provisions mTLS infrastructure | Writes certificates to configured paths, updates IP whitelist, transitions to authenticated mode |\n1100 \n1101 ---\n1102 \n1103 ### Rate Limiting\n1104 \n1105 | Endpoint | Limit | Window | Scope |\n1106 |----------|-------|--------|-------|\n1107 | `POST /api/v1/enroll` | 1 request | Per minute | Per source IP address |\n1108 | `GET /api/v1/enroll/status/{token}` | No explicit limit | \u2014 | Host-controlled polling interval |\n1109 \n1110 **Rate Limit Enforcement:**\n1111 - POST `/enroll`: Enforced by manager using in-memory LRU cache keyed on source IP (or `X-Forwarded-For` first entry when behind reverse proxy)\n1112 - Status endpoint: No server-side rate limiting; client controls poll frequency (default: 60s interval)\n1113 \n1114 ---\n1115 \n1116 ### Security Notes\n1117 \n1118 | Concern | Mitigation |\n1119 |---------|------------|\n1120 | **Initial connection security** | TLS verification disabled on enrollment client (`danger_accept_invalid_certs`).

Never log the raw token value (only hash stored in DB). Tokens expire after 24 hours by default |\n1122 | **Host identity** | `machine_id` from `/etc/machine-id` provides unique host identification. Combined with FQDN and IP for collision detection during admin approval |\n1123 | **FQDN/IP collision** | Admin approval checks existing hosts table \u2014 rejects enrollment if FQDN or IP already registered to another host (HTTP 409 Conflict) |\n1124 | **Certificate isolation** | Each approved host receives a unique client certificate signed by internal CA.

Produce a pass/fail audit report.\n\n### Files to Audit (read all first)\n- `SPEC.md` - updated with enrollment workflow, error codes, audit logging, CLI args\n- `API_DOCUMENTATION.md` - comprehensive enrollment endpoint docs with JSON schemas\n- `DEPLOYMENT_GUIDE.md` - self-enrollment deployment procedures\n- `README.md` - feature highlights and usage examples\n- `CHANGELOG.md` - enrollment feature entry under [Unreleased]\n- `ROADMAP.md` - enrollment moved to completed milestone\n- `configs/config.yaml.example` - enrollment config section documented\n- `src/enroll/client.rs` - actual implementation (verify docs match code)\n- `src/enroll/mod.rs` - run_enrollment orchestration\n- `src/enroll/provision.rs` - PKI provisioning logic\n- `src/main.rs` - CLI args definition\n- `tasks/enrollment-dev-plan.md` - design decisions reference\n\n### Audit Checklist\n\n#### 1. Terminology Consistency\n- [ ] \"self-enrollment\" vs \"enrollment\" usage is consistent across all docs\n- [ ] \"linux_patch_manager\" naming consistent (not \"manager\" alone, not mixed case)\n- [ ] \"PKI bundle\" terminology used consistently (not \"cert bundle\", \"certificate package\")\n- [ ] Error code naming matches: ENROLLMENT_DENIED, ENROLLMENT_EXPIRED, etc.\n\n#### 2. CLI Documentation Accuracy\n- [ ] `--enroll <MANAGER_URL>` flag documented correctly in SPEC.md, README.md, DEPLOYMENT_GUIDE.md\n- [ ] Flag behavior matches actual clap definition in src/main.rs\n- [ ] Help text examples are accurate and testable\n\n#### 3.
