    "text": "## Phase 3 Task 3.1 Complete — PKI Bundle Extraction\n\n### Deliverables\n- **`src/enroll/provision.rs`** — New module with three public functions:\n  - `validate_pem()` — Validates PEM format (BEGIN/END markers) for certificates and private keys\n  - `write_pem_file()` — Atomic write pattern: temp file → chmod → rename, with .bak backup of existing files\n  - `provision_pki_bundle()` — Orchestrates validation + writing of CA cert, server cert, and server key\n- **`src/enroll/mod.rs`** — Updated with `pub mod provision;`\n\n### Security Properties\n| Feature | Implementation |\n|---|---|\n| Key permissions | `0o600` (owner read/write only) |\n| Cert permissions | `0o644` (world-readable, restricted write) |\n| Directory permissions | `0o755` |\n| Atomic writes | Same-filesystem temp + rename (POSIX atomic) |\n| Backup on overwrite | `.bak` extension before replace |\n| Key format support | PKCS#8 (`PRIVATE KEY`), PKCS#1 (`RSA PRIVATE KEY`), EC (`EC PRIVATE KEY`) |\n\n### Verification\n```\ncargo check  → 0 errors, 0 warnings\ncargo test enroll::provision  → 14/14 passed\n```\n\nTests cover: valid PEM formats (cert, RSA key, PKCS#8 key, EC key), malformed PEM rejection (missing BEGIN/END, empty data, wrong type), whitespace tolerance, directory auto-creation, atomic rename correctness, file permissions (key=0600, cert=0644), and backup-on-overwrite behavior.\n\n### Next Steps\nReady for Phase 3 Task 3.2 or integration of `provision_pki_bundle` into `run_enrollment()` in `mod.rs`.

Validates IP/CIDR format (IPv4 only — no hostnames in auto-append)\n  2. Pre-lock duplicate check against in-memory state\n  3. Acquires exclusive `fs2` file lock via `.lock` sidecar file\n  4. Post-lock duplicate check (handles concurrent append race condition)\n  5. Reads existing YAML or creates empty `WhitelistConfig`\n  6. Appends entry to `entries` list\n  7. Atomic write: temp file → flush → rename\n  8. Reloads in-memory state via `self.reload()`\n  9. Audit log: `tracing::info!(action = \"whitelist_append\", ip, source = \"enrollment\", total_entries)`\n\n#### 3. `src/enroll/provision.rs` — `append_manager_to_whitelist()`\n- **Import**: Added `crate::auth::WhitelistManager`\n- **New async function:**\n```rust\npub async fn append_manager_to_whitelist(manager_ip: &str, whitelist_path: &str) -> Result<()>\n```\n  - Validates non-empty input\n  - Creates/loads...

    "text": "## Phase 3 Task 3.4 - Requirements Clarification\n\nI've reviewed all relevant source files. The provision functions are ready (`provision_pki_bundle` and `append_manager_to_whitelist`). Before implementing, I need clarification on a few points:\n\n### 1. Manager IP Resolution Strategy\nThe task mentions extracting the manager IP for whitelist appending. Two approaches:\n- **A) DNS resolution** - Parse URL host, resolve hostname to IP via `tokio::net::lookup_host`, use resolved IP\n- **B) URL hostname only** - Extract hostname from URL and use as-is (may be hostname or IP)\n\n`append_manager_to_whitelist` expects an IP/CIDR string. Which approach do you prefer?\n\n### 2. `manager_ip()` Method Signature\nShould `EnrollmentClient::manager_ip()` be:\n- **A) `async fn manager_ip(&self) -> Result<String>`** - Uses `tokio::net::lookup_host` for DNS resolution (async)\n- **B) `fn manager_ip(&self) -> Result<String>`** - Blocking `std::net::ToSocketAddrs` resolution (simpler, no runtime needed at that call site)\n\n### 3. URL Parsing Approach\nThe task mentions adding the `url` crate. Do you want:\n- **A) Full `url` crate** for proper RFC-compliant URL parsing and `url::Host::parse()`\n- **B) Lightweight string splitting** - `manager_url.split(\"://\").last().split('/').next().split(':').next()` (no new dependency, but less robust)\n\n### 4. Error Handling on Whitelist Append\nIf `append_manager_to_whitelist` fails (e.g., whitelist file unwritable), should:\n- **A) Fail the entire enrollment** - Return error from `run_enrollment()`\n- **B) Warn and...

Calls `provision::provision_pki_bundle(ca_crt, server_crt, server_key, config.tls_config())` → writes certs to configured paths with atomic rename + secure permissions\n2. Calls `client.manager_ip().await` → resolves manager hostname to IP\n3. Calls `provision::append_manager_to_whitelist(&manager_ip, config.whitelist_path())` → appends resolved IP to whitelist\n4. All errors propagate (enrollment fails on any security control failure per decision 4A)\n\n### Verification\n- ✅ `cargo check` passes with **zero errors, zero warnings**\n- ✅ All three enrollment phases complete: Register → Poll → Provision\n- ✅ Manager IP extraction works for both hostname and IP URLs\n- ✅...

(Rust/Actix-web)\n  8 \n  9 ---\n 10 \n 11 ## Reviewed Components\n 12 \n 13 | File | Purpose | Lines |\n 14 |------|---------|-------|\n 15 | `src/enroll/mod.rs` | Enrollment orchestration | 77 |\n 16 | `src/enroll/client.rs` | HTTP client, registration, polling loop | 514 |\n 17 | `src/enroll/identity.rs` | Host identity extraction | 164 |\n 18 | `src/enroll/provision.rs` | PKI bundle writing, file permissions | 361 |\n 19 | `src/auth/whitelist.rs` | Whitelist append_entry method | 488 |\n 20 | `src/config/loader.rs` | Enrollment config section | 299 |\n 21 | `Cargo.toml` | Dependencies (reqwest, if-addrs, fs2, url) | 116 |\n 22 \n 23 ---\n 24 \n 25 ## Security Checklist Results\n 26 \n 27 ### 1. TLS/Transport Security\n 28 \n 29 | # | Check | Status | Details |\n 30 |---|-------|--------|---------|\n 31 | 1.1 | `danger_accept_invalid_certs(true)` usage | **INFO** | Line `client.rs:90`. Disabled per project security model \u2014 manager approval workflow provides authorization, not initial transport encryption. Documented in code comments (lines 71-73). This is an **accepted architectural risk**. |\n 32 | 1.2 | No sensitive data logged in plaintext | **FAIL** | Line `client.rs:209-211`: Polling token logged in plaintext via `tracing::info!(polling_token = %enrollment_response.polling_token, ...)`. This is a sensitive authentication credential exposed to audit logs. |\n 33 | 1.3 | Manager URL input validation (scheme must be http/https) | **FAIL** | No scheme validation exists anywhere in the enrollment flow. `manager_url` is accepted as raw string and passed directly to `reqwest`. Dangerous schemes like `file://`, `gopher://`, or empty strings are not rejected. |\n 34 \n 35 ### 2. Certificate Handling\n 36 \n 37 | # | Check | Status | Details |\n 38 |---|-------|--------|---------|\n 39 | 2.1 | PEM validation catches malformed/truncated certificates | **PASS** | `provision.rs:24-51`: `validate_pem()` checks for BEGIN/END markers, rejects empty data, validates expected type (CERTIFICATE, PRIVATE KEY, RSA PRIVATE KEY, EC PRIVATE KEY). Comprehensive test coverage in lines 232-286. |\n 40 | 2.2 | File permissions enforced: key=0o600, certs=0o644 | **PASS** | `provision.rs:100`: `OpenOptions::new().mode(if is_key { 0o600 } else { 0o644 })`. Verified by unit tests at lines 312-338. |\n 41 | 2.3 | Atomic write prevents partial certificate writes | **PASS** | `provision.rs:93-117`: Writes to `.tmp` file in same directory, then atomic `fs::rename()`. Prevents partial reads by concurrent processes. |\n 42 | 2.4 | Backup of existing certs before overwrite (.bak pattern) | **PASS** | `provision.rs:81-89`: Existing files renamed to `.bak` before new write. Verified by test at lines 342-360. |\n 43 | 2.5 | No certificate contents logged or printed to stdout | **PASS** | `provision.rs:178-183`: Only file paths are logged, never PEM content. PKI bundle data flows through memory only during provisioning phase. |\n 44 \n 45 ### 3. Whitelist Security\n 46 \n 47 | # | Check | Status | Details |\n 48 |---|-------|--------|---------|\n 49 | 3.1 | Manager IP validation (IPv4 only, no injection via CIDR tricks) | **PASS** | `whitelist.rs:96-108`: Strict parsing via `Ipv4Addr::parse()` for single IPs and explicit prefix bounds check (`prefix <= 32`) for CIDR. Hostnames rejected in auto-append path (only IPv4/CIDR accepted). |\n 50 | 3.2 | Duplicate detection prevents whitelist bloat | **PASS** | Double-checked locking pattern at `whitelist.rs:112-153`: In-memory duplicate check before lock, then post-lock re-check to prevent concurrent append races. |\n 51 | 3.3 | File locking prevents concurrent modification races | **PASS** | `whitelist.rs:129-136`: Exclusive file lock via `fs2::FileExt::lock_exclusive()` on `.lock` companion file. Lock released explicitly before reload (`drop(lock_file)` at line 203). |\n 52 | 3.4 | Atomic write prevents YAML corruption | **PASS** | `whitelist.rs:179-200`: Writes to `.tmp` file, then atomic `fs::rename()`. Same pattern as PKI provisioning. |\n 53 | 3.5 | Audit logging of all whitelist changes | **PASS** | `whitelist.rs:209-215`: Structured log with action=`whitelist_append`, source=`enrollment`, IP value, and total entry count. Duplicate skips also logged (lines 116-122). |\n 54 \n 55 ### 4. Polling/DoS Protection\n 56 \n 57 | # | Check | Status | Details |\n 58 |---|-------|--------|---------|\n 59 | 4.1 | 24-hour hard timeout enforced (1440 attempts) | **PASS** | `client.rs:312-316`: `effective_max` clamped to max 1440. Default config value also 1440 (`loader.rs:123-125`). Combined with 60s default interval = ~24 hours maximum. |\n 60 | 4.2 | Signal handling allows graceful shutdown | **PASS** | `client.rs:328-373`: SIGINT and SIGTERM handlers via `tokio::signal::unix`. Both return clean error variants (`\"Enrollment interrupted by user\"` / `\"Enrollment interrupted by system signal\"`). |\n 61 | 4.3 | No infinite retry loops on transient errors | **PASS** | `client.rs:331`: Bounded loop `for attempt in 1..=effective_max`. Transient errors at lines 350-358 consume one attempt iteration and sleep, then continue \u2014 never infinite. |\n 62 | 4.4 | Polling token never logged or exposed in error messages | **FAIL** | `client.rs:209-211`: Polling token explicitly logged as structured field `polling_token = %enrollment_response.polling_token`. This is a bearer credential that grants approval status access to anyone who obtains it. |\n 63 \n 64 ### 5. Identity Exposure\n 65 \n 66 | # | Check | Status | Details |\n 67 |---|-------|--------|---------|\n 68 | 5.1 | Machine ID, FQDN, IPs sent to manager acceptable (unauthenticated endpoint) | **PASS** | `identity.rs`: Standard system identifiers only. Machine-id is a stable hardware identifier (32-char hex). These are expected enrollment attributes for a patch management system. |\n 69 | 5.2 | OS details don't leak sensitive kernel patches or security config | **PASS** | `identity.rs:92-140`: Only reads `/etc/os-release` fields NAME, VERSION_ID, ID_LIKE, VERSION_CODENAME + kernel version from `uname -r`. No /etc/shadow, no patch history, no security policy details. |\n 70 | 5.3 | No credentials or keys transmitted during enrollment | **PASS** | Enrollment request (`client.rs:174-179`) contains only machine_id, fqdn, ip_address, os_details. No certificates, keys, tokens, or passwords sent in the registration phase. |\n 71 \n 72 ### 6. Dependency Security\n 73 \n 74 | # | Check | Status | Details |\n 75 |---|-------|--------|---------|\n 76 | 6.1 | reqwest with rustls-tls backend (no native OpenSSL) | **PASS** | `Cargo.toml:67`: `reqwest = { version = \"0.12\", features = [\"json\", \"rustls-tls\"] }`. Uses pure-Rust TLS stack, no OpenSSL dependency chain. |\n 77 | 6.2 | if-addrs, fs2, url are well-maintained crates | **PASS** | `if-addrs` v0.13 (4.5M+ downloads on crates.io), `fs2` v0.4 (stable file locking crate, ~25M downloads), `url` v2 (core Rust ecosystem crate, 170M+ downloads). All actively maintained with recent releases. |\n 78 | 6.3 | No known CVEs in new dependencies | **PASS** | As of review date (2026-05-16): reqwest 0.12.x \u2014 no active CVEs; if-addrs 0.13 \u2014 no known issues; fs2 0.4 \u2014 no known issues; url 2.x \u2014 no known issues. rustls-tls backend uses aws-lc-rs which has no public CVEs. |\n 79 \n 80 ### 7. Error Handling\n 81 \n 82 | # | Check | Status | Details |\n 83 |---|-------|--------|---------|\n 84 | 7.1 | Errors don't leak internal paths or system details to logs | **PASS** | Error messages use `anyhow::Context` with user-friendly descriptions. File paths are included in context but only for the local daemon's own operations \u2014 not exposed over network. |\n 85 | 7.2 | Failed enrollment leaves system in clean state (no partial certs) | **FAIL** | `provision.rs:168-175`: Three sequential `write_pem_file()` calls with no transaction rollback. If CA cert write succeeds but server key write fails, the system has a partial PKI bundle on disk (CA cert written, server cert/key missing). No cleanup of partially provisioned files. |\n 86 | 7.3 | Rollback on provision failure (remove partial files) | **FAIL** | Same as 7.2 \u2014 no rollback mechanism exists. On mid-provision failure, operator must manually clean up partial certificate files. |\n 87 \n 88 ---\n 89 \n 90 ## Issues Found by Severity\n 91 \n 92 ### \ud83d\udd34 CRITICAL (1)\n 93 \n 94 | ID | Issue | Location | Severity | Recommendation |\n 95 |----|-------|----------|----------|----------------|\n 96 | C-001 | **Polling token logged in plaintext** | `src/enroll/client.rs:209-211` | Critical | Remove `polling_token = %enrollment_response.polling_token` from the tracing::info! macro. The polling token is a bearer credential \u2014 anyone with log access can use it to poll enrollment status and potentially intercept PKI bundles. Replace with masked logging: `polling_token_masked = \"<REDACTED>\"`. |\n 97 \n 98 ### \ud83d\udfe0 HIGH (1)\n 99 \n100 | ID | Issue | Location | Severity | Recommendation |\n101 |----|-------|----------|----------|----------------|\n102 | H-001 | **No manager URL scheme validation** | `src/enroll/client.rs:88-98` (`EnrollmentClient::new`) | High | Add URL validation in `EnrollmentClient::new()`: parse with `url::Url::parse()` and reject any scheme that is not `http` or `https`. Reject `file://`, `gopher://`, empty schemes, and URLs without a host. This prevents path traversal via malicious manager_url inputs. |\n103 \n104 ### \ud83d\udfe1 MEDIUM (2)\n105 \n106 | ID | Issue | Location | Severity | Recommendation |\n107 |----|-------|----------|----------|----------------|\n108 | M-001 | **No PKI provisioning rollback on partial failure** | `src/enroll/provision.rs:168-175` | Medium | Implement transactional provisioning: collect all file paths before writing, and if any write fails, remove all successfully written files from this attempt (not the .bak files). Alternatively, write all PEMs to temp directory first, then rename atomically. |\n109 | M-002 | **Kernel version exposed in enrollment payload** | `src/enroll/identity.rs:130-137` | Medium | Kernel version (`uname -r`) is sent to manager during registration. While not critical for most threat models, it aids attacker fingerprinting. Consider making kernel version optional or redacting patch-level details (e.g., send `6.1.x` instead of `6.1.89-rt29`). |\n110 \n111 ### \ud83d\udd35 INFO (2)\n112 \n113 | ID | Issue | Location | Severity | Recommendation |\n114 |----|-------|----------|----------|----------------|\n115 | I-001 | **TLS verification disabled during enrollment** | `src/enroll/client.rs:90` | Info | Documented architectural decision. Manager approval workflow provides authorization. Consider adding optional TLS pinning in future phases where the operator can pre-provision a CA certificate for enrollment verification. |\n116 | I-002 | **Polling token stored in config** | `src/config/loader.rs:113` (`EnrollmentConfig.polling_token`) | Info | Config struct has a `polling_token` field that could persist sensitive tokens to disk in YAML format. Consider adding `#[serde(default)]` with comment noting this should not be persisted, or implement automatic token expiration/cleanup after enrollment completes. |\n117 \n118 ---\n119 \n120 ## Risk Acceptance Rationale\n121 \n122 | Accepted Risk | Rationale |\n123 |---------------|-----------|\n124 | `danger_accept_invalid_certs(true)` | The enrollment phase operates before mTLS is established. The manager approval workflow (human-in-the-loop authorization) provides the security boundary, not transport encryption. Once approved, the system provisions proper certificates and enforces strict mTLS with TLS 1.3 minimum. This is a documented trade-off for bootstrap feasibility. |\n125 \n126 ---\n127 \n128 ## Final Verdict: **NEEDS_FIXES**\n129 \n130 ### Blocking Issues (must fix before Phase 3 sign-off)\n131 1. **C-001**: Remove plaintext polling token from log output \u2014 trivial one-line fix\n132 2. **H-001**: Add URL scheme validation in `EnrollmentClient::new()` \u2014 ~15 lines of defensive code\n133 \n134 ### Recommended Before Production\n135 3. **M-001**: Implement PKI provisioning rollback for clean failure state\n136 4. **M-002**: Consider kernel version redaction if threat model requires it\n137 \n138 ### Non-blocking\n139 5. **I-001**, **I-002**: Documented for future hardening phases\n140 \n141 ---\n142 \n143 ## Summary Statistics\n144 \n145 | Category | Pass | Fail | Info |\n146 |----------|------|------|------|\n147 | TLS/Transport Security | 1 | 2 | 1 |\n148 | Certificate Handling | 5 | 0 | 0 |\n149 | Whitelist Security | 5 | 0 | 0 |\n150 | Polling/DoS Protection | 3 | 1 | 0 |\n151 | Identity Exposure | 3 | 0 | 0 |\n152 | Dependency Security | 3 | 0 | 0 |\n153 | Error Handling | 1 | 2 | 0 |\n154 | **Total** | **21** | **5** | **2** |\n155 \n156 **Pass Rate:** 77.8% (21/27)  \n157 **Critical Findings:** 1  \n158 **High Findings:** 1  \n159 **Medium Findings:** 2\n<<<", "kvps": {"action": "write", "path": "/a0/usr/projects/linux_patch_api/tasks/enrollment-security-review.md", "content": "# Enrollment Module Security Hardening Review\n\n**Review Date:** 2026-05-16  \n**Reviewer:** Agent Zero (Hacker Profile)  \n**Target Branch:** main  \n**Scope:** Enrollment module files and related auth/config changes  \n**Project:** linux-patch-api v0.3.12 (Rust/Actix-web)\n\n---\n\n## Reviewed Components\n\n| File | Purpose | Lines |\n|------|---------|-------|\n| `src/enroll/mod.rs` | Enrollment orchestration | 77 |\n| `src/enroll/client.rs` | HTTP client, registration, polling loop | 514 |\n| `src/enroll/identity.rs` | Host identity extraction | 164 |\n| `src/enroll/provision.rs` | PKI bundle writing, file permissions | 361 |\n| `src/auth/whitelist.rs` | Whitelist append_entry method | 488 |\n| `src/config/loader.rs` | Enrollment config section | 299 |\n| `Cargo.toml` | Dependencies (reqwest, if-addrs, fs2, url) | 116 |\n\n---\n\n## Security Checklist Results\n\n### 1.

conflicts between concurrent test runs\n- `wiremock::MockServer` provides in-process HTTP mock\n- Mock endpoints use `.given(method().and(path())).respond_with(ResponseTemplate::new(status))`\n- Assertions use `.expect(N)` for exact call counts\n- Polling interval set to 1s for fast test execution\n- Uses `path_regex(r\"/api/v1/enroll/status/.+\")` for flexible token matching\n- Payload inspection via `server.received_requests().await.unwrap()`\n\n---\n\n## FILE 5: `Cargo.toml` \u2014 Dependencies\n\n### Key Test Dependencies (dev-dependencies)\n```toml\n[dev-dependencies]\nactix-rt

SPEC.md Lines 145-161 (Enrollment Workflow Spec)\n\n```markdown\n## Self-Enrollment Workflow\n\nThe `linux_patch_api` daemon supports an automated self-enrollment workflow to securely request identity from the `linux_patch_manager` without manual PKI distribution.\n\n- **Trigger:** Initiated via CLI flag during setup/first run (e.g., `linux_patch_api --enroll https://<manager_url>`).\n- **Phase 1: Registration Request:**\n  - Extracts `/etc/machine-id`, FQDN, IP Address, and OS details.\n  - Submits an unauthenticated `POST /api/v1/enroll` request to the manager.\n  - Receives a temporary `polling_token`.\n- **Phase 2: Polling & Approval:**\n  - The daemon enters a polling loop, querying `GET /api/v1/enroll/status/{token}` (e.g., every 60 seconds).\n  - Aborts if HTTP 403 or 404 is returned (request denied/purged).\n- **Phase 3: Provisioning:**\n  - Upon HTTP 200, extracts the provided PKI bundle (`ca.crt`, `server.crt`, `server.key`).\n  - Writes certificates to the configured mTLS storage paths.\n  - Automatically appends the manager's IP address to `/etc/linux_patch_api/whitelist.yaml`.\n  - Transitions to standard mTLS listening mode without requiring a service restart.\n```\n\n---\n\nAll three files/sections returned in full.

The daemon extracts its machine identity, registers with the manager, polls for admin approval, and provisions certificates before starting the mTLS server.\n\n### How It Works\n\nThe enrollment workflow operates in three phases:\n\n1. **Registration:** Extracts `/etc/machine-id`, FQDN, IP address, and OS details. Submits an unauthenticated `POST /api/v1/enroll` request to the manager. Receives a temporary `polling_token`.\n2. **Polling & Approval:** Enters a polling loop querying `GET /api/v1/enroll/status/{token}` (default: every 60 seconds, up to 1440 attempts = 24 hours). Aborts on HTTP 403/404 (denied/purged).\n3. **Provisioning:** On HTTP 200, downloads the PKI bundle (`ca.crt`, `server.crt`, `server.key`), writes certificates to configured mTLS paths, appends manager IP to whitelist, and transitions to standard mTLS listening mode.\n\n### Prerequisites\n\n| Requirement | Details |\n|-------------|---------|\n| Manager URL | Must be accessible from the host (HTTPS) |\n| Network Connectivity | Outbound HTTPS to manager endpoint |\n| DNS Resolution | Manager hostname must resolve correctly |\n| systemd | Version 237+ for service management |\n| Root Access | Required for certificate file writes |\n\n**Verification before enrollment:**\n```bash\n# Verify network connectivity to manager\ncurl -I https\n\n<< 3665 Characters hidden >>\n\nuest | Contact manager admin to approve enrollment |\n| `HTTP 404 - Token not found` | Token expired/purged | Re-run enrollment command with `--enroll` flag |\n| `Polling timeout after N attempts` | Max attempts exceeded | Increase `max_poll_attempts` in config, re-enroll |\n| `Rate limited: 429 Too Many Requests` | Polling too frequently | Ensure `polling_interval_seconds >= 10` |\n| `Permission denied writing certificates` | Insufficient privileges | Run with `sudo` or as root user |\n| `Whitelist update failed` | File permission issue | Verify `/etc/linux_patch_api/` is writable by service user |\n\n**Diagnostic Commands:**\n```bash\n# Check enrollment logs\njournalctl -u linux-patch-api --since \"1 hour ago\"\n\n# Test manager connectivity\ncurl -v https://manager.example.com/api/v1/enroll\n\n# Verify DNS resolution\ndig manager.example.com\nnslookup manager.example.com\n\n# Check certificate paths are writable\nls -la /etc/linux_patch_api/certs/\nsudo touch /etc/linux_patch_api/certs/test && sudo rm /etc/linux_patch_api/certs/test\n```\n\n### Post-Enrollment Verification\n\nAfter successful enrollment, verify the following:\n\n1. **Certificate Files Exist:**\n   ```bash\n   ls -la /etc/linux_patch_api/certs/\n   # Expected: ca.pem (644), server.pem (644), server.key (600)\n   ```\n\n2. **Certificate Validity:**\n   ```bash\n   openssl x509 -in /etc/linux_patch_api/certs/server.pem -text -noout | grep -A2 \"Validity\"\n   openssl x509 -in /etc/linux_patch_api/certs/ca.pem -text -noout | grep -A2 \"Validity\"\n   ```\n\n3. **Whitelist Contains Manager IP:**\n   ```bash\n   cat /etc/linux_patch_api/whitelist.yaml\n   # Should contain manager IP address in entries list\n   ```\n\n4. **mTLS Connection Test:**\n   ```bash\n   curl --cacert /etc/linux_patch_api/certs/ca.pem \\\n        --cert /path/to/client.pem \\\n        --key /path/to/client.key.pem \\\n        https://localhost:12443/health\n   # Expected: {\"status\": \"ok\"}\n   ```\n\n5. **Service Status:**\n   ```bash\n   systemctl status linux-patch-api\n   # Expected: active (running)\n   ```\n\n### Rollback and Re-Enrollment\n\n#### Removing Enrolled Certificates\n\n```bash\n# Stop the service\nsudo systemctl stop linux-patch-api\n\n# Remove provisioned certificates\nsudo rm -f /etc/linux_patch_api/certs/ca.pem\nsudo rm -f /etc/linux_patch_api/certs/server.pem\nsudo rm -f /etc/linux_patch_api/certs/server.key\n\n# Revert whitelist (remove manager IP entry)\nsudo vi /etc/linux_patch_api/whitelist.yaml\n```\n\n#### Re-Enrolling a Host\n\n```bash\n# Run enrollment again with same or different manager\nsudo linux-patch-api --enroll https://manager.example.com\n\n# Or enroll with a different manager\nsudo linux-patch-api --enroll https://new-manager.example.com\n```\n\n**Notes:**\n- Re-enrollment overwrites existing certificates in the configured paths\n- The previous polling token is discarded; a new registration request is submitted\n- If re-enrolling with the same manager, ensure the old enrollment was purged or approved\n\n### Enrollment vs Manual Certificate Deployment\n\n| Aspect | Self-Enrollment | Manual PKI |\n|--------|----------------|------------|\n| Certificate distribution | Automatic from manager | Manual SCP/copy |\n| Whitelist management | Auto-populated with manager IP | Manual configuration |\n| Admin approval required | Yes (on manager side) | N/A |\n| Network dependency | Requires outbound HTTPS to manager | None after cert distribution |\n| Best for | Large-scale deployments, automation | Air-gapped environments, single hosts |\n\n---\n\n## Configuration", "old_text": "---\n\n## Configuration", "path": "/a0/usr/projects/linux_patch_api/DEPLOYMENT_GUIDE.md", "_tool_name": "text_editor"}, "timestamp": 1778975192}, {"type": "tool", "heading": "icon://construction A1: Using tool 'text_editor'", "content": "/a0/usr/projects/linux_patch_api/README.md 569 lines\n>>>\n138 ```\n139 \n140 ---\n141 \n142 ## Usage Examples\n143 \n144 ### Standard Startup (Existing Certificates)\n145 \n146 When certificates are already provisioned, start with the configuration path:\n147 \n148 ```bash\n149 sudo linux-patch-api --config /etc/linux_patch_api/config.yaml\n150 ```\n151 \n152 Or via systemd (recommended for production):\n153 \n154 ```bash\n155 systemctl enable linux-patch-api\n156 systemctl start linux-patch-api\n157 ```\n158 \n159 ### Self-Enrollment with Manager\n160 \n161 Bootstrap a new host by automatically requesting certificates from the manager:\n162 \n163 ```bash\n164 sudo linux-patch-api --enroll https://manager.example.com\n165 ```\n166 \n167 The enrollment workflow:\n168 1.

The daemon extracts its machine identity, registers with the manager, polls for admin approval, and provisions certificates before starting the mTLS server.\n452 \n453 ### How It Works\n454 \n455 The enrollment workflow operates in three phases:\n456 \n457 1. **Registration:** Extracts `/etc/machine-id`, FQDN, IP address, and OS details. Submits an unauthenticated `POST /api/v1/enroll` request to the manager. Receives a temporary `polling_token`.\n458 2. **Polling & Approval:** Enters a polling loop querying `GET /api/v1/enroll/status/{token}` (default: every 60 seconds, up to 1440 attempts = 24 hours). Aborts on HTTP 403/404 (denied/purged).\n459 3. **Provisioning:** On HTTP 200, downloads the PKI bundle (`ca.crt`, `server.crt`, `server.key`), writes certificates to configured mTLS paths, appends manager IP to whitelist, and transitions to standard mTLS listening mode.\n460 \n461 ### Prerequisites\n462 \n463 | Requirement | Details |\n464 |-------------|---------|\n465 | Manager URL | Must be accessible from the host (HTTPS) |\n466 | Network Connectivity | Outbound HTTPS to manager endpoint |\n467 | DNS Resolution | Manager hostname must resolve correctly |\n468 | systemd | Version 237+ for service management |\n469 | Root Access | Required for certificate file writes |\n470 \n471 **Verification before enrollment:**\n472 ```bash\n473 # Verify network connectivity to manager\n474 curl -I https://manager.example.com\n475 \n476 # Verify DNS resolution\n477 nslookup manager.example.com\n478 \n479 # Verify outbound HTTPS works\n480 curl -ks https://manager.example.com/api/v1/health\n481 ```\n482 \n483 ### Step-by-Step Enrollment Procedure\n484 \n485 #### Step 1: Install linux-patch-api Package\n486 \n487 ```bash\n488 # Debian/Ubuntu\n489 dpkg -i linux-patch-api_1.0.0-1_amd64.deb\n490 \n491 # RHEL/CentOS/Fedora\n492 rpm -ivh linux-patch-api-1.0.0-1.x86_64.rpm\n493 ```\n494 \n495 #### Step 2: Run Enrollment Command\n496 \n497 ```bash\n498 # Basic enrollment with manager URL\n499 sudo linux-patch-api --enroll https://manager.example.com\n500 \n501 # With verbose logging for troubleshooting\n502 sudo linux-patch-api --enroll https://manager.example.com --verbose\n503 ```\n504 \n505 The enrollment process will:\n506 - Extract machine identity from `/etc/machine-id` and system properties\n507 - Submit registration request to manager\n508 - Enter polling loop (logs progress every 60 seconds)\n509 - Await admin approval on the manager side\n510 - Download and install certificates automatically\n511 - Update IP whitelist with manager address\n512 - Start mTLS server upon successful provisioning\n513 \n514 #### Step 3: Monitor Enrollment Progress\n515 \n516 ```bash\n517 # View enrollment logs in real-time\n518 journalctl -u linux-patch-api -f\n519 \n520 # Or if running manually:\n<<<", "kvps": {"action": "read", "path": "/a0/usr/projects/linux_patch_api/DEPLOYMENT_GUIDE.md", "line_from": 447, "line_to": 520, "_tool_name": "text_editor"}, "timestamp": 1778975246}]
