+**Async Dispose Pattern:** +```typescript +test("example with async dispose", async () => { + await using tmp = await tmpdir() + // tmp.path available + // automatically cleaned up after test +}) +``` + +**Instance.provide Pattern:** +```typescript +// Provides project context for tests +await Instance.provide({ + directory: tmp.path, + fn: async () => { + // Code runs with project context set

They want to access it securely from anywhere — coffee shop, phone browser, different machines. Currently the web UI has no authentication gate. + +**Cockpit as reference:** Cockpit's auth model is the gold standard here. No shadow users, no invented permissions. PAM says yes/no, session maps to UNIX user, commands run as that user.

Auth Broker (Privileged Helper) + +**Purpose:** Handle all privilege-sensitive operations - PAM auth, session-UID mapping, process spawning. + +**Key responsibilities:** +- Receive credentials from Hono server via Unix socket +- Call PAM for authentication (`pam_authenticate`, `pam_acct_mgmt`) +- Create session entries mapping session token -> (UID, GID, username) +- Spawn processes with correct UID/GID using `setuid`/`setgid` +- Manage process lifecycle (signal forwarding, cleanup) + +**Security boundary:** +- Runs as root OR is a setuid binary +- ONLY accepts connections from Hono server (socket permissions) +- Validates all inputs strictly +- Audit logs all authentication attempts + +```typescript +// Conceptual broker interface +interface AuthBroker { + // Authentication + authenticate(username: string, password: string): Promise; + validateSession(sessionID: string): Promise; + logout(sessionID: string): Promise; + + // Process execution + spawn(sessionID: string, command: string, args: string[], options: SpawnOptions): Promise; + + // Session management + createSession(uid: number, gid: number, username: string): Promise; + refreshSession(sessionID: string): Promise; +} + +interface AuthResult { + success: boolean; + sessionID?: string; + error?: string; +} + +interface UserInfo { + uid: number; + gid: number; + username: string; + homeDir: string; + shell: string; +} +``` + +#### 3.

Session tokens need high entropy. + +**Example:** + +```typescript +import { randomBytes } from 'node:crypto'; + +function generateSessionToken(): string { + return randomBytes(32).toString('base64url'); // 256 bits of entropy +} +``` + +### Pattern 3: PAM Service File + +**What:** Create dedicated PAM service file for opencode. + +**When:** Setting up PAM authentication. + +**Why:** Allows customization without modifying system auth. + +**Example:** + +``` +# /etc/pam.d/opencode +auth required pam_unix.so +account required pam_unix.so +session required pam_unix.so +``` + +Or to use system defaults: + +``` +# /etc/pam.d/opencode +@include common-auth +@include common-account +@include common-session +``` + +### Pattern 4: Process Group for Cleanup + +**What:** Spawn user processes in their own process group. + +**When:** Spawning commands. + +**Why:** Allows killing entire process tree on session end or abort. + +**Example:** + +```typescript +import { spawn } from 'node:child_process'; + +const child = spawn(command, args, { + uid: userInfo.uid, + gid: userInfo.gid, + detached: true, // New process group + // ... +}); + +// To kill entire tree: +process.kill(-child.pid, 'SIGTERM'); // Negative PID = process group +``` + +## Anti-Patterns to Avoid + +### Anti-Pattern 1: Storing UID in Session Cookie + +**What:** Including UID/username directly in the cookie value. + +**Why bad:** Cookie can be tampered with. User could change UID to another user's. + +**Instead:** Store only opaque session token in cookie. Broker maintains session->UID mapping server-side. + +### Anti-Pattern 2: Hono Server Running as Root + +**What:** Running the web-facing server with root privileges. + +**Why bad:** Any vulnerability in web layer = full system compromise. + +**Instead:** Web layer runs unprivileged. Only Auth Broker needs root, and it has minimal attack surface (only Unix socket, no HTTP parsing). + +### Anti-Pattern 3: Long-Lived Sessions Without Refresh + +**What:** Session tokens that are valid for days/weeks without activity check. + +**Why bad:** Stolen cookie remains valid indefinitely. + +**Instead:** Short base expiry (1 hour), extend on activity. "Remember me" = longer expiry but still requires refresh. + +### Anti-Pattern 4: PAM Calls in Hot Path + +**What:** Calling PAM on every request. + +**Why bad:** PAM is slow (may consult LDAP, etc.). Performance disaster. + +**Instead:** PAM only on login. Session validation is local lookup (memory or file). + +### Anti-Pattern 5: Passing Shell Commands as Strings + +**What:** `spawn('/bin/sh', ['-c', userInput])` + +**Why bad:** Command injection if userInput contains shell metacharacters. + +**Instead:** Pass command and args as array, let kernel handle execution. Never interpolate user input into shell strings. + +## Build Order (Suggested Phases) + +Based on dependencies and complexity: + +### Phase 1: Session Middleware Foundation + +**Build:** +- Session cookie middleware for Hono +- In-memory session store (stub for real broker) +- Session-aware API routes (require auth) +- Login/logout routes (stub with mock users) +- Session expiration logic + +**Dependencies:** Existing Hono server +**Enables:** Testing auth flow end-to-end without PAM complexity + +### Phase 2: Auth Broker Core + +**Build:** +- Auth Broker daemon structure +- Unix socket IPC protocol +- PAM integration (native module or FFI) +- Session store (file-based) +- Basic spawn capability (setuid/setgid) + +**Dependencies:** Phase 1 (to have endpoints calling broker) +**Enables:** Real authentication, but not yet command execution as user + +**Critical decision:** How to interface with PAM from Node.js/Bun +- Option A: Native addon (node-pam, etc.) +- Option B: Shell out to `su` or helper binary +- Option C: Rust/C helper binary that broker spawns + +### Phase 3: User Process Spawning + +**Build:** +- Extend Pty.create() to accept UID/GID +- Broker-mediated PTY spawning +- Process I/O proxying through broker +- Process lifecycle management (kill on session end) +- Tool execution routing through broker + +**Dependencies:** Phase 2 (broker exists, can spawn) +**Enables:** Commands actually run as authenticated user + +### Phase 4: Login UI & Security Hardening + +**Build:** +- Web login form (SolidJS) +- Insecure connection detection (HTTP without proxy) +- Warning/blocking for insecure login +- Audit logging +- Rate limiting on login attempts +- Session refresh on activity + +**Dependencies:** Phase 3 (full flow works) +**Enables:** Production-ready security posture + +### Phase 5: Multi-User Polish + +**Build:** +- User-scoped data directories +- Session isolation verification +- Documentation (nginx/Caddy reverse proxy setup) +- Configuration in opencode.json +- Graceful degradation (auth disabled = current behavior) + +**Dependencies:** Phase 4 (security in place) +**Enables:** Production deployment by users + +## Integration with Existing Architecture + +### Changes to Existing Components + +| Component | Current | Changes Needed | +|-----------|---------|----------------| +| `Pty.create()` | Spawns as current user | Add UID/GID parameters, route through broker | +| `server/server.ts` | No auth middleware | Add session cookie middleware, login routes | +| `Instance` | Tied to current user's dirs | Support user-scoped paths based on session | +| `Storage` | Writes as current user | Ensure writes happen as authenticated user | +| `Bus` | Global events | May need user-scoped event streams | + +### New Components + +| Component | Location | Purpose | +|-----------|----------|---------| +| Auth Broker | `packages/opencode/src/auth-broker/` | Privileged PAM/spawn daemon | +| Session Middleware | `packages/opencode/src/server/middleware/auth.ts` | Cookie validation | +| Login Routes | `packages/opencode/src/server/routes/auth.ts` | Login/logout endpoints | +| Login UI | `packages/app/src/routes/login.tsx` | Web login form | + +## Confidence Assessment + +| Area | Confidence | Notes | +|------|------------|-------| +| Overall architecture pattern | HIGH | Cockpit uses this exact model; well-established pattern | +| Component boundaries | HIGH | Standard privilege separation principles | +| PAM integration specifics | MEDIUM | Bun/Node PAM libraries need verification | +| Unix socket IPC | HIGH | Standard pattern, well-supported | +| Session cookie security | HIGH | Standard web security practices | +| Build order | MEDIUM | May need adjustment based on PAM library availability | + +## Open Questions for Phase-Specific Research + +1. **PAM library for Bun:** Does `node-pam` or similar work with Bun?

This is fundamentally different from typical web authentication because the goal is not just "who is this user?" but "run this command as this user." The Cockpit project provides the canonical reference implementation for this pattern, and our research strongly recommends following their architectural approach. + +The recommended approach is a two-component design: the existing Hono server runs unprivileged and handles HTTP/session cookies, while a new "auth broker" (setuid helper binary) handles PAM authentication and spawns user processes with correct UID/GID. This separation is non-negotiable from a security perspective. Running the web server as root to simplify PAM access would create catastrophic security exposure where any web vulnerability becomes a full root compromise. + +Key risks center on privilege management and PAM integration complexity. The auth broker must be implemented carefully (likely in C or Rust for minimal attack surface), PAM conversation functions must handle all message types correctly, and session tokens must use cryptographically secure generation. Bun's native module compatibility with existing PAM libraries is uncertain, which reinforces the setuid helper approach over direct PAM library integration. + +## Key Findings + +### Recommended Stack + +The existing Hono/Bun/TypeScript stack remains unchanged for the web layer.

The auth broker receives credentials via Unix socket, performs PAM authentication, creates session entries mapping tokens to UIDs, and spawns processes with correct setuid/setgid. User processes execute actual commands under the authenticated user's identity with correct HOME, USER, SHELL environment. + +**Major components:** +1. **Hono Server (unprivileged)** — HTTP handling, session cookies, route dispatch; runs as nobody/daemon +2. **Auth Broker (root/setuid)** — PAM authentication, session-UID mapping, process spawning; minimal attack surface +3. **Session Store** — File-based (SQLite/JSON) in root-owned directory with 0600 permissions +4. **User Process** — Spawned commands running as target UID/GID with correct environment + +### Critical Pitfalls + +1. **Running web server as root** — Any web vulnerability becomes root compromise. Prevent via strict privilege separation: unprivileged web server, separate setuid helper for PAM and spawning. + +2. **PAM conversation function misuse** — Incorrect handling of PAM message types leads to auth bypass or memory corruption. Prevent by handling all 4 message types (echo on/off, error, text info), using established wrappers, implementing timeouts. + +3. **Session token predictability** — Weak tokens enable session hijacking. Prevent via crypto.randomBytes(32), minimum 256 bits of entropy, never reuse tokens. + +4. **Credentials in logs/memory** — Passwords appearing in logs or error messages. Prevent via explicit redaction before logging, generic error messages ("invalid credentials" not "password mismatch"), clear memory immediately after PAM call. + +5. **Command injection via user input** — User-controlled input reaching shell commands. Prevent via array-based spawn (never shell=true with user input), parameter sanitization; note opencode already has tree-sitter parsing in bash tool. + +## Implications for Roadmap + +Based on research, suggested phase structure: + +### Phase 1: Session Middleware Foundation +**Rationale:** Session infrastructure must exist before any authentication can be tested. This phase builds the foundation without touching PAM complexity. +**Delivers:** Session cookie middleware, in-memory session store (stub), session-aware API routes, login/logout routes with mock auth, session expiration logic +**Addresses:** Session cookies, logout, session timeout (partial) +**Avoids:** Over-engineering storage before auth works + +### Phase 2: Auth Broker Core +**Rationale:** The privileged component is the highest-complexity, highest-risk element. Building it early allows parallel UI development and integration testing. +**Delivers:** Auth broker daemon structure, Unix socket IPC protocol, PAM integration, file-based session store, basic spawn capability +**Uses:** Setuid helper (C/Rust), Unix socket pattern, PAM service file +**Implements:** Auth broker component, session store +**Avoids:** Running web server as root, PAM conversation bugs, weak session tokens + +### Phase 3: User Process Spawning +**Rationale:** Depends on auth broker existing. Completes the "run as user" capability that is the core value proposition. +**Delivers:** PTY creation with UID/GID, broker-mediated command execution, process I/O proxying, process lifecycle management +**Uses:** Existing Pty.create() extended with UID/GID parameters +**Implements:** User process component, tool execution routing +**Avoids:** Command injection, privilege escalation + +### Phase 4: Login UI and Security Hardening +**Rationale:** UI can be developed in parallel once API contracts exist. Security hardening adds defense-in-depth after core flow works. +**Delivers:** SolidJS login form, HTTPS detection/warning, audit logging, rate limiting on login, session refresh on activity +**Addresses:** Login form, HTTPS warning, brute-force protection, CSRF protection (complete) +**Avoids:** User enumeration via timing, credentials over HTTP, missing cookie attributes + +### Phase 5: Multi-User Polish +**Rationale:** Polish features after core functionality is secure and working. +**Delivers:** User-scoped data directories, session isolation verification, reverse proxy documentation, opencode.json configuration, graceful degradation (auth disabled = current behavior) +**Addresses:** Remember me, multi-session awareness, session activity indicator + +### Phase Ordering Rationale + +- **Sessions before PAM**: Testing auth flow end-to-end with mock users validates middleware before introducing PAM complexity +- **Broker before UI**: The broker defines API contracts; UI depends on them, not vice versa +- **Spawning after broker**: Cannot spawn as user without working session-to-UID mapping +- **Security hardening after core flow**: Defense-in-depth adds layers; getting the happy path right first reduces rework +- **Polish last**: Features like "remember me" extend working session management, don't change it + +### Research Flags + +Phases likely needing deeper research during planning: +- **Phase 2 (Auth Broker Core):** Bun N-API compatibility with PAM libraries needs runtime verification; may determine C vs Rust vs Bun FFI for helper +- **Phase 3 (User Process Spawning):** PTY ownership with user impersonation via bun-pty needs testing; may need bun-pty modifications + +Phases with standard patterns (skip research-phase): +- **Phase 1 (Session Middleware):** Hono cookie middleware is well-documented, existing codebase patterns apply +- **Phase 4 (Login UI):** Standard SolidJS form, existing app patterns apply +- **Phase 5 (Multi-User Polish):** Configuration and documentation, no novel patterns + +## Confidence Assessment + +| Area | Confidence | Notes | +|------|------------|-------| +| Stack | HIGH (web), MEDIUM (helper) | Hono middleware verified in codebase;

not available on Apple platforms + - What's unclear: How to handle supplementary groups on macOS (opendirectoryd?) + - Recommendation: Use initgroups which works on macOS, verify behavior + +3. **PAM session with nonstick** + - What we know: Existing broker uses nonstick for auth, but session mgmt "coming soon" + - What's unclear: Timeline for nonstick session support + - Recommendation: Add pam-client for session mgmt, or use libc pam bindings directly + +4. **utmp on macOS** + - What we know: macOS uses different utmp/wtmp paths and format + - What's unclear: Whether pututxline works

Configure allowed proxy IPs and reject the header from other sources. +- **Using === for token comparison:** String equality checks leak timing information. Always use `crypto.timingSafeEqual()` for security-sensitive comparisons. +- **Naive double-submit cookie:** Sending random token in cookie + body without HMAC signing is vulnerable to subdomain cookie injection. Always use HMAC binding to session. +- **HttpOnly CSRF cookie:** The double-submit pattern requires JavaScript to read the cookie value. Setting HttpOnly breaks the pattern. +- **Global rate limiting:** Applying rate limits to all routes causes false positives. Rate limit only high-risk endpoints like login. + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Rate limiting store | Custom in-memory Map with cleanup | hono-rate-limiter or rate-limiter-flexible | Memory leaks, race conditions, sliding window complexity | +| CSRF token generation | Math.random() or Date.now() | crypto.randomBytes() | crypto.randomBytes() uses OS-level CSPRNG; Math.random() is predictable | +| String comparison | string1 === string2 for tokens | crypto.timingSafeEqual() | Timing attacks can leak token contents character-by-character | +| HMAC implementation | Custom hash functions | crypto.createHmac() | OpenSSL-backed, constant-time, battle-tested | +| Retry-After calculation | Custom date formatting | Standard HTTP-date or seconds | Clients expect RFC 7231 format; custom formats break compatibility | + +**Key insight:** Security primitives have subtle requirements (constant-time operations, cryptographic randomness, proper key derivation) that are easy to get wrong. Use battle-tested libraries. + +## Common Pitfalls + +### Pitfall 1: CSRF Token Without Session Binding +**What goes wrong:** Generating CSRF tokens without tying them to the authenticated session allows attackers to use their own token on victim requests. +**Why it happens:** Simpler to implement random token without session context; naive double-submit pattern examples omit this step. +**How to avoid:** Always include session ID in HMAC calculation: `hmac(secret, sessionId + randomValue)`. Validate session matches token. +**Warning signs:** CSRF tokens work across different logged-in users; attacker can generate valid token for victim. + +### Pitfall 2: Leaking Rate Limit Details +**What goes wrong:** Error messages reveal exact retry times or remaining attempts, helping attackers optimize brute force timing. +**Why it happens:** Desire to be helpful to legitimate users; verbose error mode enabled in production. +**How to avoid:** Generic message by default: "Too many attempts. Please try again later." Log detailed info server-side. Only enable verbose errors in development. +**Warning signs:** Error responses include "4 attempts remaining" or exact retry timestamp in message body. + +### Pitfall 3: Trusting X-Forwarded-Proto from Anywhere +**What goes wrong:** Attackers spoof X-Forwarded-Proto header to bypass HTTPS enforcement, claiming connection is secure when it's not. +**Why it happens:** Checking header without validating request source; not configuring trusted proxy list. +**How to avoid:** Only trust X-Forwarded-Proto when request comes from known reverse proxy IPs. Otherwise, use direct protocol detection. +**Warning signs:** HTTPS enforcement can be bypassed by adding header manually; localhost connections blocked incorrectly. + +### Pitfall 4: Session Fixation After Login +**What goes wrong:** User logs in but session ID doesn't change, allowing attacker with pre-login session ID to hijack authenticated session. +**Why it happens:** Forgetting to regenerate session ID after authentication state change; reusing CSRF token across login boundary. +**How to avoid:** Destroy old session and create new one after successful login. Regenerate CSRF token with new session ID. +**Warning signs:** Session IDs persist across login; CSRF token valid before and after authentication. + +### Pitfall 5: Rate Limiting by IP Only in Production +**What goes wrong:** Attackers using distributed botnets bypass IP-based limits; legitimate users behind NAT get blocked together. +**Why it happens:** IP tracking is simplest to implement; context specifies IP-only approach. +**How to avoid:** Context decision mandates IP-only (simpler approach). Document limitation. Consider username tracking in future phase if needed. +**Warning signs:** Corporate networks with shared IP report lockouts; attacker rotates IPs to bypass limits. + +### Pitfall 6: XSS Enables CSRF Bypass +**What goes wrong:** Cross-site scripting vulnerability allows attacker to read CSRF token from page/cookie and include it in forged request. +**Why it happens:** CSRF protection assumes attacker cannot execute JavaScript in victim's context; XSS breaks this assumption. +**How to avoid:** CSRF tokens are NOT a defense against XSS. Must also prevent XSS through output encoding, CSP, input validation. +**Warning signs:** CSRF protection bypassed when malicious script injected into page. + +### Pitfall 7: Logging Passwords and Tokens +**What goes wrong:** Security logging accidentally captures plaintext passwords, CSRF tokens, or session IDs in audit trails. +**Why it happens:** Logging entire request body or headers without filtering; helpful debugging that becomes vulnerability. +**How to avoid:** Mask sensitive fields before logging. Use allowlist approach: log only specific safe fields. Never log Authorization, Cookie, or X-CSRF-Token headers. +**Warning signs:** Log files contain "password": "actual_password"; grep for tokens finds them in logs. + +## Code Examples + +Verified patterns from official sources: + +### CSRF Middleware Implementation +```typescript +// Source: OWASP + Hono patterns +import { createMiddleware } from 'hono/factory' +import crypto from 'crypto' + +interface CSRFConfig { + secret: string + cookieName: string + headerName: string + skipIfNoAuth: boolean + allowlist: string[] + verboseErrors: boolean +} + +export const csrfProtection = (config: CSRFConfig) => { + return createMiddleware(async (c, next) => { + // Skip for safe methods + const method = c.req.method + if (method === 'GET' || method === 'HEAD' || method === 'OPTIONS') { + return next() + } + + // Skip if auth disabled and configured to do so + if (config.skipIfNoAuth && !c.get('user')) { + return next() + } + + // Skip if route is in allowlist + const path = new URL(c.req.url).pathname + if (config.allowlist.some(pattern => path.startsWith(pattern))) { + return next() + } + + // Get token from cookie + const cookieToken = await c.req.cookie(config.cookieName) + if (!cookieToken) { + return c.json({ + error: 'csrf_required', + message: config.verboseErrors ?

`generateCSRFToken(sessionId, secret)` - Creates HMAC-signed tokens + - `validateCSRFToken(token, sessionId, secret)` - Validates with constant-time comparison + - `getCSRFSecret()` - Retrieves secret from env or generates one + - Token format: `{signature}.{randomValue}` where signature = HMAC-SHA256(sessionId:randomValue) + +2. **CSRF Middleware** (`src/server/middleware/csrf.ts`) + - Validates CSRF tokens on state-changing requests (POST, PUT, DELETE, PATCH) + - Skips validation for safe methods (GET, HEAD, OPTIONS) + - Skips validation when auth is disabled (no session to bind to) + - Allowlist: `/auth/login`, `/auth/status`, plus custom routes from config + - Returns 403 with error codes: `csrf_required` or `csrf_invalid` + +3. **Integration with Auth Flow** + - Login: Sets CSRF cookie after successful authentication + - Logout: Clears CSRF cookie along with session cookie + - Server: CSRF middleware added after auth middleware in chain + - Config: Added `csrfVerboseErrors` and `csrfAllowlist` to AuthConfig + +4. **Comprehensive Test Coverage** + - Token utilities: 15 tests covering generation, validation, edge cases + - Middleware: 17 tests covering safe methods, auth disabled, allowlist, validation + - All tests pass with high coverage + +## Technical Decisions + +### Double-Submit Cookie Pattern + +**Decision:** Use double-submit cookie pattern instead of server-side token storage. + +**Rationale:** +- Stateless approach aligns with existing in-memory session design +- No additional storage overhead +- Token validation requires only crypto operations, no database lookup + +**Implementation:** +- Cookie stores the HMAC-signed token (readable by client, SameSite=Lax) +- Client sends same token in X-CSRF-Token header +- Server validates they match AND HMAC signature is valid + +### HMAC Session Binding + +**Decision:** Bind CSRF tokens to session ID using HMAC signature. + +**Rationale:** +- Prevents token fixation attacks where attacker tries to use their token on victim's session +- Even if attacker can set cookie, they cannot forge valid signature without secret +- Signature computed as: HMAC-SHA256(sessionId:randomValue, secret) + +**Security benefit:** +``` +Attacker scenario: +1. Attacker generates token for their sessionId: token_a +2. Attacker tricks victim into accepting cookie with token_a +3. Victim makes request with their sessionId: session_v +4. Server validates: HMAC(session_v:random) != signature_a +5. Request rejected ✓ +``` + +### Constant-Time Comparison + +**Decision:** Use `crypto.timingSafeEqual` for signature validation. + +**Rationale:** +- Prevents timing attacks that could leak signature information +- Standard practice for cryptographic comparisons +- Node.js built-in provides secure implementation + +### Non-HttpOnly Cookie + +**Decision:** CSRF cookie is NOT HttpOnly (unlike session cookie). + +**Rationale:** +- Double-submit pattern requires client to read cookie value +- Client must send same value in header for validation +- Cookie is still protected by SameSite=Lax and Secure flags +- HMAC signature prevents tampering + +**Trade-off:** +- XSS vulnerability could read CSRF token +- BUT: XSS can already make authenticated requests directly +- CSRF protects against cross-origin attacks, not XSS + +## Implementation Details + +### Token Format + +``` +{signature}.{randomValue} + ↓ ↓ +64 hex chars 64 hex chars +(SHA256) (32 random bytes) +``` + +Example: `a7f3...c2e9.d4b1...8f6a` + +### Validation Flow + +``` +POST /api/something +Cookie: opencode_csrf= +X-CSRF-Token: + +1.

Compare tokens (must match) +7. Get sessionId from context +8. Validate HMAC signature +9. Allow or deny (403) +``` + +### Allowlist Routes + +Default allowlist (cannot be changed): +- `/auth/login` - Sets initial CSRF cookie, cannot validate one +- `/auth/status` - Read-only endpoint + +Custom allowlist (via config): +```typescript +auth: { + csrfAllowlist: ["/api/webhook", "/api/public"] +} +``` + +## Security Properties + +1. **Protection against CSRF attacks** ✓ + - Attacker cannot forge requests from malicious site + - Even if cookie is set, signature validation fails + +2. **Protection against token fixation** ✓ + - Tokens bound to specific sessionId via HMAC + - Cannot reuse token across sessions + +3. **Timing attack resistance** ✓ + - Constant-time comparison prevents timing leaks + +4. **Session invalidation on logout** ✓ + - CSRF cookie cleared along with session cookie + +5. **HTTPS enforcement** ✓ + -

The codebase already has the necessary infrastructure: Hono's cookie helpers, SolidJS with @kobalte/core for UI components (Toast and Dialog), and the `ms` library for duration parsing. + +The standard approach for "remember me" is to set a longer `maxAge` on the session cookie (30 days vs. the default 7 days). Session activity should refresh silently by piggybacking on existing API requests rather than creating a dedicated refresh endpoint. Expiration warnings should use toast notifications (non-blocking) 15 minutes before timeout, with a modal overlay if the session expires while the user is active. + +**Primary recommendation:** Use Hono's `setCookie` with conditional `maxAge` based on "remember me" checkbox, implement activity-based refresh via middleware that updates `lastAccessTime` on every authenticated request, and use existing @kobalte Toast/Dialog components for warnings and expiration overlays. + +## Standard Stack + +The established libraries/tools for this domain: + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| Hono cookie helpers | 4.10.7 | Session cookie management | Already in use; supports maxAge, secure, httpOnly, sameSite | +| @kobalte/core | 0.13.11 | Toast and Dialog components | Already in use; accessible, SolidJS-native | +| ms | 2.1.3 | Duration parsing | Already in use; tiny, well-maintained by Vercel | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| SolidJS signals | 1.9.10 | Reactive session state tracking | Frontend session timer/countdown | +| Hono middleware | 4.10.7 | Activity detection via request interception | Silent session refresh on API calls | + +### Alternatives Considered +| Instead of | Could Use | Tradeoff | +|------------|-----------|----------| +| @kobalte Toast | solid-toast | solid-toast is simpler but @kobalte already in project | +| Activity piggybacking | Dedicated /refresh endpoint | Dedicated endpoint adds extra requests; piggybacking is invisible | +| Cookie maxAge | localStorage expiry | Cookies are HttpOnly (more secure); localStorage vulnerable to XSS | + +**Installation:** +No new dependencies required. All necessary libraries already installed. + +## Architecture Patterns + +### Recommended Project Structure +``` +packages/opencode/src/ +├── server/ +│ ├── middleware/ +│ │ └── auth.ts # Extend with remember-me logic +│ └── routes/ +│ └── auth.ts # Add remember-me checkbox handling +packages/app/src/ +├── components/ +│ └── session-status-indicator.tsx # Username dropdown with logout +├── context/ +│ └── session-monitor.tsx # Activity tracking & expiration warnings +``` + +### Pattern 1: Persistent Cookie via maxAge +**What:** Session cookies without `maxAge` delete on browser close. Setting `maxAge` creates a persistent cookie. +**When to use:** When "remember me" checkbox is checked. +**Example:** +```typescript +// Source: https://hono.dev/docs/helpers/cookie +import { setCookie } from "hono/cookie" + +// Session cookie (deleted on browser close) +setCookie(c, "opencode_session", sessionId, { + path: "/", + httpOnly: true, + sameSite: "Strict", + secure: isHttps, + // No maxAge or expires = session cookie +}) + +// Persistent cookie (survives browser restart) +const rememberMeDuration = parseDuration("30d") // 30 days in ms +setCookie(c, "opencode_session", sessionId, { + path: "/", + httpOnly: true, + sameSite: "Strict", + secure: isHttps, + maxAge: rememberMeDuration / 1000, // maxAge is in SECONDS, not ms +}) +``` +**CRITICAL:** Hono's `maxAge` option is in **seconds**, not milliseconds. Divide `parseDuration()` result by 1000. + +### Pattern 2: Activity-Based Session Refresh +**What:** Update `lastAccessTime` on every authenticated request to extend idle timeout. +**When to use:** For all authenticated API calls (already implemented in existing auth middleware). +**Example:** +```typescript +// Source: Current codebase pattern +// packages/opencode/src/server/middleware/auth.ts lines 123-124 + +// Update lastAccessTime (sliding expiration) +UserSession.touch(sessionId) +``` +**Current implementation:** Middleware already calls `UserSession.touch(sessionId)` on every request. This is the "piggyback" pattern - no changes needed for basic activity refresh. + +### Pattern 3: Frontend Session Monitoring +**What:** Track time until expiration and show warnings in the UI. +**When to use:** When user is actively viewing the page. +**Example:** +```typescript +// Pattern: Poll /auth/session endpoint to get lastAccessTime +// Calculate remaining time = (lastAccessTime + timeout) - Date.now() +// Show toast when remainingTime < 15 minutes + +import { createSignal, onCleanup } from "solid-js" +import { showToast } from "@opencode-ai/ui/components/toast" + +function SessionMonitor() { + const [remainingMs, setRemainingMs] = createSignal(null) + + // Poll session status every 60 seconds + const interval = setInterval(async () => { + const res = await fetch("/auth/session") + if (res.ok) { + const session = await res.json() + const timeout = parseDuration("7d") // Or get from config + const remaining = (session.lastAccessTime + timeout) - Date.now() + setRemainingMs(remaining) + + // Warn 15 minutes before expiry + if (remaining < 15 * 60 * 1000 && remaining > 0) { + showWarningToast() + } + } + }, 60000) + + onCleanup(() => clearInterval(interval)) +} +``` +**Throttle recommendation:** Poll every 60 seconds. Less frequent polling (2-5 minutes) acceptable for low-risk applications. + +### Pattern 4: Session Expiration Warning Toast +**What:** Non-blocking notification 15 minutes before session expires. +**When to use:** When countdown reaches warning threshold. +**Example:** +```typescript +// Source: Existing @kobalte toast pattern +import { showToast } from "@opencode-ai/ui/components/toast" + +function showSessionWarningToast() { + showToast({ + title: "Session expiring soon", + description: "Your session will expire in 15 minutes", + variant: "default", + icon: "clock", // Or appropriate icon + persistent: true, // Don't auto-dismiss + actions: [ + { + label: "Extend session", + onClick: async () => { + // Trigger activity by calling any authenticated endpoint + await fetch("/auth/session") // This refreshes lastAccessTime + } + } + ] + }) +} +``` + +### Pattern 5: Session Expired Overlay +**What:** Modal overlay when session expires while user is active on the page. +**When to use:** When poll detects session no longer exists or expired. +**Example:** +```typescript +// Source: @kobalte Dialog pattern +import { Dialog } from "@kobalte/core/dialog" +import { createSignal } from "solid-js" + +function SessionExpiredOverlay() { + const [open, setOpen] = createSignal(false) + + // Triggered when session poll returns 401 + function showExpiredOverlay() { + setOpen(true) + } + + return ( + + + + + Session Expired + + Your session has expired. Please log in again to continue. + + + + + + ) +} +``` +**Context preservation:** Overlay appears over current page, user can see their work before being redirected. + +### Anti-Patterns to Avoid +- **Countdown in UI:** Showing exact seconds/minutes remaining is confusing and creates anxiety. Show warning only when close to expiry. +- **Dedicated refresh endpoint:** Creates extra HTTP traffic. Piggyback on existing authenticated requests instead. +- **Client-side timeout calculation only:** Must validate server-side. Client clock may be wrong or manipulated. +- **Remember me without duration limit:** Always cap at 30-400 days per security best practices. + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Cookie max-age calculation | Manual date math | Hono `maxAge` with `ms()` | Hono enforces 400-day RFC6265bis limit, handles edge cases | +| Toast notifications | Custom positioned divs | @kobalte Toast (already installed) | Handles stacking, animations, accessibility, screen readers | +| Modal overlays | z-index + backdrop | @kobalte Dialog (already installed) | Manages focus trapping, scroll blocking, ESC key, ARIA | +| Duration parsing | String splitting/regex | `ms` library (already installed) | Handles "30d", "7 days", "1h" formats consistently | +| Activity detection | Manual event listeners | Middleware-based touch on API calls | Captures all activity (not just clicks), no frontend overhead | + +**Key insight:** The codebase already has all necessary primitives. Session enhancements are about **composing existing tools**, not building new infrastructure. + +## Common Pitfalls + +### Pitfall 1: maxAge Units Confusion +**What goes wrong:** Setting `maxAge: parseDuration("30d")` results in ~2.6 billion second expiry (83 years instead of 30 days). +**Why it happens:** Hono's `maxAge` is in **seconds**, but `parseDuration()` returns **milliseconds**. +**How to avoid:** Always divide by 1000: `maxAge: parseDuration("30d") / 1000` +**Warning signs:** Cookie inspector shows expiry date decades in the future. + +### Pitfall 2: Remember Me Cookie Without Server Timeout Change +**What goes wrong:** Cookie persists 30 days but server expires session after 7 days idle. User returns day 10, cookie exists but session is gone. +**Why it happens:** Cookie expiry and session idle timeout are separate concerns. +**How to avoid:** When "remember me" is checked, use longer server-side timeout too (same duration as cookie maxAge). +**Warning signs:** Users report "remember me doesn't work" after returning from multi-day break. + +### Pitfall 3: Polling During Inactivity +**What goes wrong:** Session monitor polls every 60s even when user switched tabs, wasting resources and preventing idle timeout. +**Why it happens:** `setInterval` runs regardless of page visibility. +**How to avoid:** Use Page Visibility API or pause polling when document.hidden is true. +**Warning signs:** Backend logs show session refreshes from "idle" users; sessions never actually time out. + +### Pitfall 4: Session Warning After Expiry +**What goes wrong:** Warning toast appears but session already expired, "Extend" button fails. +**Why it happens:** Poll interval (60s) is longer than warning window (900s), so detection lags. +**How to avoid:** Either poll more frequently as expiry approaches, or show warning with sufficient buffer (15 min before + 60s poll = 16 min warning threshold). +**Warning signs:** Users click "Extend session" button and get "session expired" error. + +### Pitfall 5: Logout Invalidates Cookie But Not Session +**What goes wrong:** User clicks logout, cookie is deleted, but session persists in server memory. If attacker steals old session ID, it still works. +**Why it happens:** Logout handler calls `clearSessionCookie()` but not `UserSession.remove()`. +**How to avoid:** Always clear both cookie AND server-side session on logout. +**Warning signs:** Old session IDs still valid after logout (security vulnerability). + +### Pitfall 6: Missing Secure Flag on Non-Localhost +**What goes wrong:** Session cookies sent over HTTP in production, vulnerable to interception. +**Why it happens:** Conditional `secure: isHttps` doesn't account for reverse proxy headers. +**How to avoid:** Check `X-Forwarded-Proto` header when behind proxy; require HTTPS in production. +**Warning signs:** Browser console warnings about insecure cookies; security audit failures. + +## Code Examples + +Verified patterns from official sources: + +### Session Cookie with Conditional Persistence +```typescript +// Source: Hono cookie docs + current codebase pattern +import { setCookie } from "hono/cookie" +import { parseDuration } from "../../util/duration" + +function setSessionCookie(c: Context, sessionId: string, rememberMe: boolean): void { + const isHttps = c.req.url.startsWith("https://") + const baseOptions = { + path: "/", + httpOnly: true, + sameSite: "Strict" as const, + secure: isHttps, + } + + if (rememberMe) { + // Persistent cookie (30 days) + const maxAgeMs = parseDuration("30d")! + setCookie(c, "opencode_session", sessionId, { + ...baseOptions, + maxAge: maxAgeMs / 1000, // Convert ms to seconds + }) + } else { + // Session cookie (deleted on browser close) + setCookie(c, "opencode_session", sessionId, baseOptions) + } +} +``` + +### Login Handler with Remember Me Checkbox +```typescript +// Source: Current /auth/login pattern, extended +const loginRequestSchema = z.object({ + username: z.string().min(1).max(32), + password: z.string().min(1), + rememberMe: z.boolean().optional(), +}) + +app.post("/auth/login", async (c) => { + const { username, password, rememberMe } = await c.req.json() + + // ... authentication logic ... + + const session = UserSession.create(username, c.req.header("User-Agent"), userInfo) + setSessionCookie(c, session.id, rememberMe ?? false) + + return c.json({ success: true, user: { username } }) +}) +``` + +### Session Status Check Endpoint +```typescript +// Source: Current /auth/session endpoint (already exists!) +// packages/opencode/src/server/routes/auth.ts lines 756-803 +app.get("/auth/session", async (c) => { + const sessionId = getCookie(c, "opencode_session") + if (!sessionId) { + return c.json({ error: "Not authenticated" }, 401) + } + const session = UserSession.get(sessionId) + if (!session) { + return c.json({ error: "Not authenticated" }, 401) + } + return c.json({ + id: session.id, + username: session.username, + createdAt: session.createdAt, + lastAccessTime: session.lastAccessTime, // Frontend needs this for countdown + uid: session.uid, + gid: session.gid, + }) +}) +``` +**Note:** This endpoint already exists!

+``` + +### Anti-Patterns to Avoid +- **Color-only distinction:** WCAG 1.4.1 violation - must use icon + color + tooltip text together, not just red/green colors alone +- **Auto-dismissing warnings:** Security warnings should require user action to dismiss, not auto-hide after timeout +- **Blocking modal on HTTP:** Don't prevent app usage with intrusive modal; use non-blocking banner + persistent badge instead +- **SVG aria-label on buttons:** Use visually-hidden text or visible text with decorative icon (aria-hidden="true") instead + +## Don't Hand-Roll + +Problems that look simple but have existing solutions: + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| Accessible tooltip | Custom position logic + ARIA | Kobalte Tooltip | Handles keyboard navigation, screen reader announcements, focus management, positioning edge cases | +| Accessible popover | Custom modal/dropdown | Kobalte Popover | WAI-ARIA compliant, manages focus trap, Escape key handling, outside click detection | +| localStorage reactivity | Manual get/set + listeners | @solid-primitives/storage | Reactive updates across components, SSR-safe, type-safe | +| Visibility detection | setInterval polling | Page Visibility API | Battery-efficient, browser-native, fires on actual visibility changes | +| Color contrast | Manual color picking | WCAG checker tools | Ensures 4.5:1 minimum ratio, catches accessibility issues | + +**Key insight:** Accessibility in UI components is complex - proper ARIA roles, keyboard navigation, focus management, and screen reader announcements require extensive testing. Kobalte components are battle-tested and WCAG 2.2 compliant. + +## Common Pitfalls + +### Pitfall 1: Color-Only Status Indication +**What goes wrong:** Using only red for HTTP and green for HTTPS violates WCAG 1.4.1 and fails for colorblind users (5% of population). +**Why it happens:** Developers assume color alone is sufficient; red/green has cultural "stop/go" meaning. +**How to avoid:** Always combine color with icon shape AND text (via tooltip). Use distinct icon shapes: lock (secure), triangle/shield with exclamation (insecure), house (local). +**Warning signs:** Only classList changing colors without icon or text changes; no aria-label or tooltip. + +### Pitfall 2: Blocking Users on HTTP +**What goes wrong:** Displaying modal that prevents app usage on HTTP connections frustrates users with legitimate reasons (dev environments, internal networks). +**Why it happens:** Over-zealous security concern; misunderstanding of threat model. +**How to avoid:** Use dismissible banner + persistent badge instead. Let users make informed choice. +**Warning signs:** Modal with no dismiss option; app unusable until HTTPS. + +### Pitfall 3: Missing Localhost Detection +**What goes wrong:** Showing "insecure" warning for localhost development, causing alert fatigue. +**Why it happens:** Only checking protocol, not hostname; unaware that browsers treat localhost as "potentially trustworthy". +**How to avoid:** Explicitly check for localhost, 127.0.0.1, ::1, and *.localhost patterns. Show neutral "local" indicator instead. +**Warning signs:** HTTP warning showing during local development; developers constantly dismissing banner. + +### Pitfall 4: Aria-Label on Icon Buttons +**What goes wrong:** Screen readers may not announce aria-label reliably on icon-only buttons across all browsers/assistive tech. +**Why it happens:** Common but suboptimal pattern; MDN examples use it. +**How to avoid:** Use visible text with icon, or visually-hidden text span with CSS (.sr-only). Keep icon decorative with aria-hidden="true". +**Warning signs:** Tooltip and aria-label duplicating same text; no visible text near icon. + +### Pitfall 5: Banner State Not Persisting +**What goes wrong:** HTTP warning banner reappears every page load/refresh despite user dismissing it. +**Why it happens:** Storing dismissal in component state instead of localStorage; not implementing persistence. +**How to avoid:** Store dismissal timestamp in localStorage; check on mount. Consider session-based persistence for temporary dismissal. +**Warning signs:** Banner reappears on refresh; users complain about repetitive warnings. + +### Pitfall 6: Layout Shift on Banner Appearance +**What goes wrong:** Banner sliding down pushes content, causing jarring Cumulative Layout Shift (CLS) - bad for Core Web Vitals. +**Why it happens:** Banner injected into flow without reserved space; animation shifts adjacent elements. +**How to avoid:** Reserve space with min-height, or use fixed/sticky positioning above content flow. Animate opacity/transform, not height. +**Warning signs:** Page content jumps when banner appears; poor Lighthouse CLS score. + +### Pitfall 7: Not Re-Checking on Visibility Change +**What goes wrong:** Security status becomes stale when user switches tabs, potentially missing proxy injection or connection changes. +**Why it happens:** Checking security only on mount; not monitoring page lifecycle. +**How to avoid:** Add visibilitychange event listener to re-check when tab becomes active. +**Warning signs:** Status doesn't update when switching networks; stale protocol indication. + +## Code Examples + +Verified patterns from official sources: + +### Detecting HTTPS/HTTP/Local +```typescript +// Source: MDN Location.protocol + MDN Secure Contexts +function getConnectionSecurity(): "secure" | "insecure" | "local" { + const protocol = window.location.protocol; + const hostname = window.location.hostname; + + // Check for potentially trustworthy local origins + // Ref: https://developer.mozilla.org/en-US/docs/Web/Security/Secure_Contexts + const isLocal = + hostname === "localhost" || + hostname === "127.0.0.1" || + hostname === "::1" || + hostname.endsWith(".localhost"); + + if (isLocal) { + return "local"; + } + + // Protocol includes the colon: "https:" or "http:" + return protocol === "https:" ?

Scan this code with your authenticator app (Apple Passwords, Google Authenticator, Authy, 1Password, etc.)

+
+ ${qrCodeSvg} +

Or enter this secret manually:

+
${secret}
+

+
${escapeHtml(setupCommand)}

This creates ~/.google_authenticator with your secret.

Step 2: Run Setup Command
+
Step 2: Install google-authenticator (if needed)
+

The google-authenticator command is part of libpam-google-authenticator, an open source PAM module.

+
+ Installation instructions +
+
Ubuntu/Debian:sudo apt install libpam-google-authenticator
+
Fedora/RHEL:sudo dnf install google-authenticator
+
Arch Linux:sudo pacman -S libpam-google-authenticator
+
macOS:brew install google-authenticator-libpam
+
+

This is free, open source software: github.com/google/google-authenticator-libpam

+
+
+ +
+
Step 3: Run Setup Command

Run this command on the server to enable 2FA for your account:

${escapeHtml(setupCommand)}

This creates ~/.google_authenticator with your secret.

Step 4: Verify Setup

Enter a code from your authenticator app to verify it's working:

This creates ~/.google_authenticator with your secret.

+
+ Is this safe? Will it affect my system login? +
+

No, this will not affect your system login.

+

The command only creates a file at ~/.google_authenticator containing your TOTP secret. This file is completely inert by itself.

+

It only affects authentication when a PAM service explicitly loads it. Your system's login, sudo, and SSH use their own PAM configs which remain untouched. Opencode uses a separate PAM service file (opencode-otp) that only opencode reads.

+

Reversibility: Simply run rm ~/.google_authenticator to undo.

The command creates a file at ~/.google_authenticator containing your TOTP secret. This file is completely inert by itself.

It only affects authentication when a PAM service explicitly loads it. Your system's login, sudo, and SSH use their own PAM configs which remain untouched. Opencode uses a separate PAM service file (opencode-otp) that only opencode reads.

-

Reversibility: Simply run rm ~/.google_authenticator to undo.

Multi-user: Each user has their own ~/.google_authenticator in their home directory. Multiple users can independently configure 2FA.

Existing file: The command will prompt before overwriting an existing configuration.

Reversibility: Run rm ~/.google_authenticator to remove 2FA.

OR configure backend to send ping frames < 60s +} +``` +**Warning signs:** "502 Bad Gateway" after exactly 60 seconds, clients reconnecting frequently +**Source:** [nginx.org WebSocket proxying](https://nginx.org/en/docs/http/websocket.html) + +### Pitfall 2: Express trust proxy Misconfiguration + +**What goes wrong:** Rate limiting breaks, IP logging shows proxy IP not client IP +**Why it happens:** Express doesn't trust X-Forwarded-* headers by default; security feature to prevent spoofing +**How to avoid:** +```javascript +// In opencode server config +app.enable('trust proxy'); +// ONLY if nginx is trusted and sets X-Forwarded-For +``` +**Warning signs:** All requests appear from same IP (127.0.0.1 or proxy IP) +**Documentation note:** Explain security implications - clients can spoof X-Forwarded-For if trust proxy is enabled without actual proxy +**Source:** [Express behind proxies](https://expressjs.com/en/guide/behind-proxies.html) + +### Pitfall 3: PAM Module Load Order + +**What goes wrong:** Authentication succeeds when it should fail, or vice versa +**Why it happens:** PAM processes modules top-to-bottom; control flags (required, sufficient, requisite) affect flow +**How to avoid:** +- Document control flag meanings: `required` (must pass, continues), `requisite` (must pass, stops on fail), `sufficient` (if pass, stops), `optional` (result ignored) +- Provide working example configurations, not just isolated lines +- Explain "sufficient" stops processing on success, so order matters +**Warning signs:** Users locked out, wrong PAM modules executing, inconsistent auth results + +### Pitfall 4: SELinux Blocking nginx-to-Node.js Connections + +**What goes wrong:** nginx returns "502 Bad Gateway", error log shows "(13: Permission denied) while connecting to upstream" +**Why it happens:** Default SELinux policy blocks httpd_t domain from network connections +**How to avoid:** +```bash +# Check if SELinux is enforcing +getenforce +# Enable HTTP network connections +sudo setsebool -P httpd_can_network_connect 1 +``` +**Warning signs:** nginx config tests fine, backend responds to curl locally, but proxy fails with permission denied +**Documentation note:** Include SELinux troubleshooting section, mention AppArmor as similar issue on Ubuntu +**Source:** [nginx SELinux configuration](https://www.getpagespeed.com/server-setup/nginx/nginx-selinux-configuration) + +### Pitfall 5: Forgetting WebSocket Headers in Chained Proxies + +**What goes wrong:** WebSocket upgrades fail through Cloudflare + nginx, HTTP fallback or errors +**Why it happens:** Each proxy layer must pass Upgrade/Connection headers; Cloudflare passes them but nginx must too +**How to avoid:** +```nginx +# Even behind Cloudflare, nginx needs these +proxy_set_header Upgrade $http_upgrade; +proxy_set_header Connection "upgrade"; +``` +**Documentation note:** Explicitly document chained proxy scenarios (Cloudflare -> nginx -> opencode) + +### Pitfall 6: HSTS with includeSubDomains on Test Domains + +**What goes wrong:** Test subdomain gets HSTS cached, can't access via HTTP for debugging +**Why it happens:** `includeSubDomains` applies HSTS to all subdomains; browsers cache for max-age duration +**How to avoid:** +- Use short max-age (300s) for testing +- Only add `includeSubDomains` and `preload` for production +- Document HSTS cannot be "undone" client-side except by waiting for max-age expiry +**Warning signs:** Browser refuses HTTP even after removing HSTS header from server +**Source:** [OWASP HSTS Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/HTTP_Strict_Transport_Security_Cheat_Sheet.html) + +### Pitfall 7: macOS Monterey PAM Directory Permissions + +**What goes wrong:** PAM configuration changes fail or require TCC approval +**Why it happens:** macOS Monterey added restrictions on `/etc/pam.d/` access +**How to avoid:** +- Document macOS-specific TCC requirements +- Explain admin consent is required for processes accessing `/etc/pam.d/` +- Note that system updates may revert `pam.d` and `sshd_config` changes +**Source:**

State of the Art + +| Old Approach | Current Approach | When Changed | Impact | +|--------------|------------------|--------------|--------| +| Manual cert renewal | Let's Encrypt + auto-renewal | ~2015-2016 | Free TLS, 90-day rotation reduces compromise window | +| supervisord/forever | systemd units | ~2015+ | Native platform integration, better logging/resource control | +| Image-based diagrams | Mermaid in markdown | ~2020+ | Version control, GitHub native rendering, easier updates | +| Single nginx config | Dual format (quick + annotated) | Current best practice | Serves both expert (quick copy) and learning (explanation) needs | +| PAM-only auth | PAM + 2FA (TOTP) | ~2018+ | Defense against credential compromise, zero-trust environments | +| HTTP-only load balancers | TLS termination at LB | Cloud-native shift | Offloads TLS from application, centralized cert management | + +**Deprecated/outdated:** +- **pam_ldap.so**: Modern systems use SSSD with pam_sss.so for LDAP authentication (more features, better caching) +- **pm2/forever for production**: systemd provides better integration, logging, and resource control +- **Self-signed certificates in production**: Let's Encrypt provides free, trusted certificates with automation +- **TLS 1.0/1.1**: Deprecated, insecure; use TLSv1.2 minimum, preferably TLSv1.3 +- **Expect-CT header**: Deprecated by Chrome, Certificate Transparency is now enforced at browser level + +## Open Questions + +Things that couldn't be fully resolved: + +1. **opencode-broker implementation details** + - What we know: Referenced in context as needing setuid/setgid, socket permissions, systemd unit documentation + - What's unclear: Exact socket path, permission requirements, whether broker exists in current codebase + - Recommendation: Document based on Phase 7 (PAM Integration) implementation; verify broker socket location and permissions during planning + +2. **Cloud provider specifics for Hetzner** + - What we know: Context mentions documenting if Hetzner offers managed TLS/certs + - What's unclear: Hetzner's managed load balancer TLS termination capabilities (search results focused on AWS/GCP/Azure) + - Recommendation: Research Hetzner Load Balancer product during writing; if no managed TLS, document self-managed nginx approach + +3. **SELinux vs AppArmor coverage depth** + - What we know: Marked as Claude's discretion; SELinux is well-documented issue with nginx + - What's unclear: How often AppArmor causes issues vs SELinux in real deployments + - Recommendation: Prioritize SELinux (RHEL/CentOS/Fedora common for servers), brief AppArmor section (Ubuntu/Debian), based on frequency of nginx permission denied issues (SELinux more common in search results) + +4. **Flowchart format/tool depth** + - What we know: Mermaid is standard, GitHub-native + - What's unclear: How complex troubleshooting flowcharts should be (simple decision trees vs detailed diagnostic flows) + - Recommendation: Start with simple 3-5 node decision trees, can expand based on common issues found during UAT + +5. **Container deployment scope** + - What we know: Explicitly deferred to separate phase/doc + - What's unclear: Should reverse-proxy.md mention "for container deployments, see docker.md" or avoid mentioning containers entirely + - Recommendation: Brief note "For Docker/container deployments, see [separate doc]" to acknowledge but redirect + +## Sources + +### Primary (HIGH confidence) +- [nginx.org WebSocket Proxying](https://nginx.org/en/docs/http/websocket.html) - Official

For 2FA setup, skip to [Two-Factor Authentication](#two-factor-authentication-2fa). + +--- + +## What is PAM? + +**PAM (Pluggable Authentication Modules)** is a flexible authentication framework used on UNIX-like systems. Instead of hardcoding authentication logic into every application, PAM allows system administrators to configure authentication policies centrally. + +### How PAM Works + +When an application (like OpenCode) needs to authenticate a user, it calls into PAM with a **service name** (e.g., "opencode"). PAM reads the corresponding configuration file (`/etc/pam.d/opencode`) and executes a **stack** of authentication modules in order. + +Each module can: +- **Succeed** (user credentials valid) +- **Fail** (credentials invalid) +- **Be ignored** (module result doesn't affect outcome) + +The final authentication result depends on the **control flags** (explained below) and the combined results of all modules. + +### Module Types + +PAM modules are organized by type: + +- **`auth`** - Authenticates the user (verifies credentials like password, OTP) +- **`account`** - Checks account validity (not expired, not locked, time restrictions) +- **`password`** - Handles password changes +- **`session`** - Sets up/tears down user sessions (environment, logging, mounts) + +Most OpenCode configurations only need `auth` and `account` modules. + +--- + +## Control Flags Explained + +Control flags determine what happens when a module succeeds or fails: + +| Flag | Behavior | +|------|----------| +| **`required`** | Must succeed for authentication to succeed. Continues to next module even on failure (to prevent timing attacks). | +| **`requisite`** | Must succeed. Stops immediately on failure (early exit). | +| **`sufficient`** | If succeeds, immediately succeeds (skip remaining modules). If fails, continues to next module. | +| **`optional`** | Result is ignored unless it's the only module in the stack. | + +### Example: Order Matters + +Consider this PAM configuration: + +``` +auth sufficient pam_unix.so +auth required pam_deny.so +``` + +**What happens:** +1. `pam_unix.so` runs first (checks password) +2. If password is correct, `sufficient` flag causes immediate success (skips `pam_deny.so`) +3. If password is wrong, continues to `pam_deny.so` which always fails +4. Result: Authentication succeeds only if password is correct + +Now reverse the order: + +``` +auth required pam_deny.so +auth sufficient pam_unix.so +``` + +**What happens:** +1. `pam_deny.so` runs first and always fails +2. `required` flag means we must continue (no early exit) +3. `pam_unix.so` runs and checks password +4. Result: Authentication **always fails** because `pam_deny.so` failed and was `required` + +**Takeaway:** Place more permissive modules (`sufficient`) before restrictive ones (`required`). + +--- + +## Basic Setup (Linux) + +### 1. Install PAM Configuration File + +OpenCode provides a basic PAM configuration for Linux systems: + +```bash +sudo cp packages/opencode-broker/service/opencode.pam /etc/pam.d/opencode +``` + +**File contents (`/etc/pam.d/opencode`):** + +``` +# PAM configuration for OpenCode authentication +# Install to /etc/pam.d/opencode + +# Standard UNIX authentication +auth required pam_unix.so +account required pam_unix.so + +# Optional: Enable TOTP 2FA (uncomment when pam_google_authenticator is installed) +# auth required pam_google_authenticator.so +``` + +**What each line does:** + +| Line | Module | Purpose | +|------|--------|---------| +| `auth required pam_unix.so` | `pam_unix.so` | Validates username/password against `/etc/shadow` | +| `account required pam_unix.so` | `pam_unix.so` | Checks account status (not expired, not locked) | + +This is the simplest configuration - it just checks system passwords. + +### 2. Install opencode-broker + +The **opencode-broker** is a privileged process that handles PAM authentication on behalf of the OpenCode web server. It runs as root (or with setuid) to access PAM and spawn user processes. + +#### Build from source: + +```bash +cd packages/opencode-broker +cargo build --release +sudo cp target/release/opencode-broker /usr/local/bin/ +``` + +#### Set permissions: + +**Option A: setuid (recommended for single-user systems):** +```bash +sudo chmod 4755 /usr/local/bin/opencode-broker +``` + +**Option B: Run as root via systemd (recommended for multi-user systems):** +```bash +sudo chmod 755 /usr/local/bin/opencode-broker +# Service runs as root (see next step) +``` + +### 3.

Enable 2FA in OpenCode + +Add 2FA configuration to `opencode.json`: + +**Basic 2FA (optional for users):** +```json +{ + "auth": { + "enabled": true, + "twoFactorEnabled": true + } +} +``` + +**Required 2FA (enforced for all users):** +```json +{ + "auth": { + "enabled": true, + "twoFactorEnabled": true, + "twoFactorRequired": true + } +} +``` + +**With custom timeouts:** +```json +{ + "auth": { + "enabled": true, + "twoFactorEnabled": true, + "twoFactorTokenTimeout": "5m", + "deviceTrustDuration": "30d", + "otpRateLimitMax": 5, + "otpRateLimitWindow": "15m" + } +} +``` + +### 4. User Setup + +Each user must configure 2FA individually: + +#### Command-Line Setup (required for PAM) + +Users must run the `google-authenticator` command on the server to create the `.google_authenticator` file: + +```bash +# Run as the user who will authenticate +google-authenticator +``` + +**Interactive prompts:** + +1. **"Do you want authentication tokens to be time-based?"** - Answer **yes** +2. Scan QR code with authenticator app (Google Authenticator, Authy, 1Password, etc.) +3. **"Do you want to update your ~/.google_authenticator file?"** - Answer **yes** +4. **"Do you want to disallow multiple uses?"** - Answer **yes** (recommended) +5. **"Do you want to allow codes from 30 seconds ago?"** - Answer **yes** (clock skew tolerance) +6. **"Do you want to enable rate-limiting?"** - Answer **yes** (recommended) + +This creates `~/.google_authenticator` with the TOTP secret. + +#### Web UI Setup (optional) + +OpenCode provides a web-based 2FA setup wizard at `/auth/setup-2fa`. This: +- Generates QR code in browser +- Walks user through authenticator app setup +- Tests OTP code before enabling + +**However:** Users must still run `google-authenticator` on the server for PAM to work. The web UI helps with the authenticator app setup, but the final step requires shell access. + +#### Backup Codes + +During `google-authenticator` setup, emergency backup codes are displayed. Users should: +- **Save backup codes** in a secure location +- Use backup codes if they lose their authenticator device +- Regenerate codes by running `google-authenticator` again + +### 5. Testing 2FA + +1. Log out of OpenCode +2. Enter username and password +3. If user has 2FA configured, OTP prompt appears +4. Enter 6-digit code from authenticator app +5. Authentication succeeds + +If user does **not** have 2FA configured (and `nullok` is set), authentication succeeds after password only. + +### 6. Enforcing 2FA + +To require all users to set up 2FA: + +1. **Remove `nullok` from PAM:** + ```bash + sudo nano /etc/pam.d/opencode-otp + # Change: + # auth required pam_google_authenticator.so nullok + # To: + # auth required pam_google_authenticator.so + ``` + +2. **Enable `twoFactorRequired` in config:** + ```json + { + "auth": { + "twoFactorRequired": true + } + } + ``` + +3. **Notify users** to set up 2FA before enforcement date + +4. **Test with a non-2FA user** to confirm enforcement works + +Users without 2FA will be unable to authenticate until they run `google-authenticator`. + +--- + +## LDAP/Active Directory Integration + +For enterprise environments, integrate OpenCode with LDAP or Active Directory using **SSSD** (System Security Services Daemon). + +### Why SSSD? + +Modern Linux distributions recommend **SSSD** over legacy `pam_ldap.so`: +- Better performance (caching) +- Offline authentication support +- Kerberos integration +- Active Directory support +- Maintained and secure + +### Setup Overview + +1. **Install and configure SSSD** (distribution-specific) +2. **Update OpenCode PAM configuration** to use `pam_sss.so` +3. **Verify authentication** works + +### Distribution-Specific Guides + +SSSD configuration varies by Linux distribution and directory service.

"Authentication failed" - Generic Error + +**Symptom:** +Login form shows "Authentication failed" with no specific details. + +**Cause:** +PAM authentication failed. By design, OpenCode returns a generic error to prevent user enumeration attacks. The specific reason is logged server-side. + +**Debug Steps:** + +1. Enable PAM debug logging (see [Enabling PAM Debug Logging](#enabling-pam-debug-logging)) + +2. Check auth logs while attempting login: + ```bash + # Linux (Debian/Ubuntu) + sudo tail -f /var/log/auth.log + + # Linux (RHEL/CentOS) + sudo tail -f /var/log/secure + + # macOS + log stream --predicate 'eventMessage contains "pam"' --level debug + ``` + +3. Look for PAM error messages: + - `pam_unix(opencode:auth): authentication failure; user=username` - Wrong password + - `pam_unix(opencode:auth): check pass; user unknown` - User doesn't exist + - `pam_unix(opencode:account): account expired` - Account locked/expired + - `pam_google_authenticator(opencode:auth): Invalid verification code` - Wrong 2FA code + +**Common Causes:** + +- **Wrong credentials** - Verify password works with `su - username` +- **User doesn't exist** - Check with `id username` +- **Account locked** - Check with `passwd -S username` (Linux) +- **2FA misconfiguration** - Verify `~/.google_authenticator` file exists if using 2FA +- **PAM service mismatch** - Verify `auth.pam.service` in `opencode.json` matches filename in `/etc/pam.d/` + +**Solution:** + +Identify the specific PAM error from logs and address accordingly. Most commonly: +- Typo in password → retry with correct password +- User needs to be created → `sudo useradd username` or equivalent +- 2FA not set up → run `google-authenticator` as the user + +### 2. "Connection refused" - Broker Not Running + +**Symptom:** +Login fails immediately with connection error. Browser console may show network error. + +**Cause:** +The `opencode-broker` service is not running or the Unix socket doesn't exist. + +**Debug Steps:** + +1. Check if broker is running: + ```bash + # Linux (systemd) + systemctl status opencode-broker + + # macOS (launchd) + sudo launchctl list | grep opencode + ``` + +2. Check if socket exists: + ```bash + # Linux + ls -l /run/opencode/auth.sock + + # macOS + ls -l /var/run/opencode/auth.sock + ``` + +3. Check broker logs: + ```bash + # Linux + journalctl -u opencode-broker -n 50 + + # macOS + log show --predicate 'process == "opencode-broker"' --last 1h + ``` + +**Common Causes:** + +- Broker service not installed +- Broker service failed to start +- Permissions issue creating socket directory +- Wrong socket path configured + +**Solution:** + +**Linux:** +```bash +# Start broker service +sudo systemctl start opencode-broker + +# Enable on boot +sudo systemctl enable opencode-broker + +# Verify running +systemctl status opencode-broker + +# Check socket created +ls -l /run/opencode/auth.sock +``` + +**macOS:** +```bash +# Load broker service +sudo launchctl load /Library/LaunchDaemons/com.opencode.broker.plist + +# Verify running +sudo launchctl list | grep opencode + +# Check socket created +ls -l /var/run/opencode/auth.sock +``` + +If broker fails to start, check logs for specific error. + +### 3. "502 Bad Gateway" - nginx Can't Connect to OpenCode + +**Symptom:** +nginx returns `502 Bad Gateway` error when accessing OpenCode. + +**Cause:** +nginx cannot reach the OpenCode backend server. + +**Debug Steps:** + +1. Check nginx error log: + ```bash + sudo tail -f /var/log/nginx/error.log + ``` + +2. Look for connection errors: + - `connect() failed (111: Connection refused)` - OpenCode not running + - `connect() failed (13: Permission denied)` - SELinux blocking nginx + +3. Verify OpenCode is running: + ```bash + # Check if OpenCode is listening on the configured port + sudo netstat -tlnp | grep + # or + sudo lsof -i : + ``` + +**Common Causes:** + +- **OpenCode not running** - Start the OpenCode server +- **Wrong port in nginx config** - Verify `proxy_pass` matches OpenCode port +- **SELinux blocking connections** - Allow nginx to make network connections +- **Firewall blocking local connections** - Check iptables/firewalld rules + +**Solution:** + +**If OpenCode not running:** +```bash +# Start OpenCode server +cd /path/to/opencode +bun run server +``` + +**If SELinux blocking (RHEL/CentOS/Fedora):** +```bash +# Check if SELinux is enforcing +getenforce + +# Check for denials +sudo ausearch -m avc -ts recent | grep httpd + +# Allow nginx to make network connections +sudo setsebool -P httpd_can_network_connect 1 + +# Restart nginx +sudo systemctl restart nginx +``` + +**If AppArmor blocking (Ubuntu/Debian):** +```bash +# Check AppArmor status +sudo aa-status + +# Check for denials +sudo dmesg | grep apparmor | grep nginx + +# May need to adjust AppArmor profile at /etc/apparmor.d/ +``` + +### 4. WebSocket Drops After 60 Seconds + +**Symptom:** +Terminal or other WebSocket connection disconnects after exactly 60 seconds of inactivity. + +**Cause:** +nginx default `proxy_read_timeout` is 60 seconds. WebSocket connections idle longer than this are terminated. + +**Debug Steps:** + +1. Test if issue is timeout-related: + - Open terminal + - Wait 60 seconds without typing + - Connection drops → timeout issue + +2. Check nginx configuration for proxy_read_timeout + +**Solution:** + +Add to nginx server block or location: +```nginx +location / { + proxy_pass http://localhost:; + + # Existing WebSocket headers... + proxy_http_version 1.1; + proxy_set_header Upgrade $http_upgrade; + proxy_set_header Connection $connection_upgrade; + + # Increase timeout for WebSocket connections (24 hours) + proxy_read_timeout 86400s; + proxy_send_timeout 86400s; +} +``` + +Reload nginx: +```bash +sudo nginx -t +sudo systemctl reload nginx +``` + +**Note:** 86400 seconds = 24 hours. Adjust based on your needs. + +### 5. Rate Limited When You Shouldn't Be + +**Symptom:** +"Too many login attempts" error on first try, or getting rate limited when you haven't made many attempts. + +**Cause:** +Rate limiting is IP-based. Multiple users behind the same NAT or proxy may share an IP address, or the wrong IP is being detected. + +**Debug Steps:** + +1. Check what IP OpenCode sees: + - Enable debug logging in OpenCode + - Look for rate limit messages in logs + - Note the IP address being rate limited + +2. Check if behind reverse proxy: + - Is there an nginx or other proxy? + - Is `trustProxy` enabled in `opencode.json`? + +3. Test with `curl` to see IP detection: + ```bash + curl -v http://your-domain.com + # Look for X-Forwarded-For header + ``` + +**Common Causes:** + +- **Multiple users sharing NAT IP** - Common in corporate or home networks +- **Proxy not forwarding real IP** - Missing X-Forwarded-For header +- **trustProxy not enabled** - OpenCode sees proxy IP, not client IP +- **Proxy IP not in trusted range** - OpenCode ignores X-Forwarded-For from untrusted proxy + +**Solution:** + +**If behind reverse proxy:** + +1. Ensure nginx (or proxy) sends X-Forwarded-For: + ```nginx + proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; + proxy_set_header X-Forwarded-Proto $scheme; + ``` + +2. Enable `trustProxy` in `opencode.json`: + ```json + { + "auth": { + "enabled": true, + "trustProxy": true + } + } + ``` + +3. Restart OpenCode server + +**If many users behind NAT:** + +1. Increase rate limits in `opencode.json`: + ```json + { + "auth": { + "enabled": true, + "rateLimitMax": 20, + "rateLimitWindow": "15m" + } + } + ``` + +2. Consider per-user rate limiting (future enhancement) + +**Temporary workaround - disable rate limiting:** +```json +{ + "auth": { + "enabled": true, + "rateLimiting": false + } +} +``` + +Note: Only disable rate limiting if behind a trusted reverse proxy that enforces its own limits. + +### 6. CSRF Token Error + +**Symptom:** +Login form shows "Invalid CSRF token" or "CSRF validation failed" when submitting. + +**Cause:** +CSRF cookie not set or doesn't match the form token. + +**Debug Steps:** + +1. Open browser DevTools → Application/Storage → Cookies +2. Look for `opencode_csrf` cookie +3. Check if cookie is set after page load +4. Try clearing cookies and reload + +**Common Causes:** + +- **Cookies disabled** - Browser settings or privacy extensions +- **Cookie domain mismatch** - Accessing via different domain than cookie was set for +- **Secure cookie over HTTP** - Cookie requires HTTPS but accessing over HTTP +- **Third-party cookie blocking** - Browser privacy settings + +**Solution:** + +**Check browser settings:** +- Ensure cookies enabled for the domain +- Disable privacy extensions temporarily (Privacy Badger, uBlock Origin, etc.) +- Try incognito/private mode + +**Check OpenCode configuration:** +- If using HTTP locally, `requireHttps` should be `"off"`: + ```json + { + "auth": { + "requireHttps": "off" + } + } + ``` + +**For reverse proxy setup:** +- Ensure nginx doesn't strip cookies: + ```nginx + # These should be present: + proxy_set_header Cookie $http_cookie; + proxy_pass_header Set-Cookie; + ``` + +**Clear cookies and retry:** +```javascript +// In browser console +document.cookie.split(";").forEach(c => { + document.cookie = c.replace(/^ +/, "").replace(/=.*/, `=;expires=${new Date().toUTCString()};path=/`); +}); +location.reload(); +``` + +### 7. 2FA Code Always Invalid + +**Symptom:** +TOTP codes from authenticator app are always rejected. + +**Cause:** +Time synchronization issue, wrong PAM service configuration, or 2FA not properly set up. + +**Debug Steps:** + +1. Verify time sync: + ```bash + # Check system time + date + + # Compare with NTP time + ntpdate -q pool.ntp.org + ``` + +2. Check user's 2FA setup: + ```bash + # As the user + ls -l ~/.google_authenticator + + # Verify file exists and readable + cat ~/.google_authenticator | head -1 + # Should show base32-encoded secret + ``` + +3. Check PAM configuration: + ```bash + cat /etc/pam.d/opencode-otp + ``` + +4. Test 2FA with google-authenticator PAM directly: + ```bash + # Install pamtester if not installed + sudo apt install pamtester # Debian/Ubuntu + + # Test authentication + pamtester opencode-otp username authenticate + ``` + +**Common Causes:** + +- **Time drift** - Server time differs from authenticator app time by >30 seconds +- **Wrong PAM service** - Using `opencode` instead of `opencode-otp` for OTP validation +- **2FA not initialized** - User hasn't run `google-authenticator` command +- **File permissions** - `~/.google_authenticator` not readable + +**Solution:** + +**Fix time synchronization (Linux):** +```bash +# Install NTP +sudo apt install systemd-timesyncd # Debian/Ubuntu +sudo yum install chrony # RHEL/CentOS + +# Enable time sync +sudo timedatectl set-ntp true + +# Verify synced +timedatectl status +``` + +**Fix time synchronization (macOS):** +```bash +# Enable automatic time +sudo systemsetup -setusingnetworktime on + +# Force sync +sudo sntp -sS time.apple.com +``` + +**Verify PAM configuration:** + +Ensure `/etc/pam.d/opencode-otp` exists and contains: +``` +auth required pam_google_authenticator.so nullok +account required pam_permit.so +``` + +**Initialize 2FA for user:** +```bash +# Run as the user (not root!) +google-authenticator + +# Answer prompts: +# - Time-based tokens: Y +# - Update ~/.google_authenticator: Y +# - Disallow multiple uses: Y +# - Rate limiting: Y +# - Increase window: N (unless time sync issues) +``` + +**Set correct permissions:** +```bash +chmod 600 ~/.google_authenticator +``` + +**Verify OpenCode configuration:** +```json +{ + "auth": { + "enabled": true, + "twoFactorEnabled": true, + "pam": { + "service": "opencode" + } + } +} +``` + +Note: The main PAM service should be `opencode`, not `opencode-otp`. The broker uses `opencode-otp` internally for OTP-only validation. + +### 8. SELinux Blocking nginx + +**Symptom:** +- nginx returns `502 Bad Gateway` +- nginx error.log shows `(13: Permission denied) while connecting to upstream` +- Happens on RHEL/CentOS/Fedora systems + +**Cause:** +SELinux policy prevents `httpd_t` (nginx) from making network connections. + +**Debug Steps:** + +1. Verify SELinux is enforcing: + ```bash + getenforce + # Output: Enforcing + ``` + +2. Check for SELinux denials: + ```bash + sudo ausearch -m avc -ts recent | grep httpd + # or + sudo grep nginx /var/log/audit/audit.log | grep denied + ``` + +3. Look for denials related to `connect`: + ``` + type=AVC msg=audit(...): avc: denied { name_connect } for pid=... comm="nginx" + dest= scontext=system_u:system_r:httpd_t:s0 + tcontext=system_u:object_r:unreserved_port_t:s0 tclass=tcp_socket permissive=0 + ``` + +**Solution:** + +**Option 1: Allow httpd network connect (recommended):** +```bash +# Allow nginx to make network connections +sudo setsebool -P httpd_can_network_connect 1 + +# Verify setting +getsebool httpd_can_network_connect +# Output: httpd_can_network_connect --> on +``` + +**Option 2: Label OpenCode port:** +```bash +# If OpenCode runs on non-standard port, label it as http_port_t +sudo semanage port -a -t http_port_t -p tcp + +# Verify +sudo semanage port -l | grep http_port_t +``` + +**Option 3: Create custom policy (advanced):** +```bash +# Generate policy from denials +sudo ausearch -m avc -ts recent | audit2allow -M opencode-nginx + +# Review the policy +cat opencode-nginx.te + +# Install policy if it looks correct +sudo semodule -i opencode-nginx.pp +``` + +**Option 4: Disable SELinux (NOT recommended for production):** +```bash +# Temporary (until reboot) +sudo setenforce 0 + +# Permanent (edit /etc/selinux/config) +sudo sed -i 's/SELINUX=enforcing/SELINUX=permissive/' /etc/selinux/config +``` + +**After applying fix:** +```bash +# Restart nginx +sudo systemctl restart nginx + +# Test connection +curl http://localhost +``` + +### 9. macOS PAM "Operation not permitted" + +**Symptom:** +On macOS Monterey (12.x) or later, PAM operations fail with "Operation not permitted" errors in logs. + +**Cause:** +macOS Transparency, Consent, and Control (TCC) restrictions prevent processes from accessing `/etc/pam.d/` without full disk access. + +**Debug Steps:** + +1. Check macOS version: + ```bash + sw_vers + # ProductVersion: 12.x or later = TCC restrictions apply + ``` + +2. Check system logs: + ```bash + log show --predicate 'eventMessage contains "pam"' --last 1h | grep denied + ``` + +3. Check if broker has full disk access: + - System Preferences → Security & Privacy → Privacy → Full Disk Access + - Look for Terminal or the app running opencode-broker + +**Common Causes:** + +- **TCC restrictions** - macOS 12+ restricts PAM operations +- **Broker not granted Full Disk Access** - Process needs explicit permission +- **SIP (System Integrity Protection)** - Protects system files + +**Solution:** + +**Option 1: Grant Full Disk Access (recommended):** + +1. Open System Preferences → Security & Privacy → Privacy +2. Select "Full Disk Access" in left sidebar +3. Click lock icon to make changes +4. Add the terminal app or process running opencode-broker: + - For Terminal: `/Applications/Utilities/Terminal.app` + - For iTerm2: `/Applications/iTerm.app` + - For systemwide: `/usr/local/bin/opencode-broker` + +5. Restart the broker process + +**Option 2: Run broker from authorized location:** + +macOS allows certain system locations to access PAM. Install broker to: +```bash +# System binary location +sudo cp opencode-broker /usr/local/bin/ +sudo chown root:wheel /usr/local/bin/opencode-broker +sudo chmod 755 /usr/local/bin/opencode-broker + +# Update launchd plist ProgramArguments path +sudo nano /Library/LaunchDaemons/com.opencode.broker.plist +# Set: /usr/local/bin/opencode-broker + +# Reload launchd +sudo launchctl unload /Library/LaunchDaemons/com.opencode.broker.plist +sudo launchctl load /Library/LaunchDaemons/com.opencode.broker.plist +``` + +**Option 3: Disable SIP (NOT recommended):** + +SIP protects critical system files.

These headers provide defense-in-depth against common web attacks. + +### trustProxy Documentation Approach + +Dedicated section explaining: +- What trustProxy does (trusts X-Forwarded-Proto header) +- When to enable (behind reverse proxy) +- Security implications (header spoofing if enabled without proxy) +- Configuration examples + +Rationale: trustProxy is critical for HTTPS detection but dangerous if misconfigured. Users need to understand the security model. + +### Cloud Provider Coverage + +Brief sections for AWS, GCP, Azure, Cloudflare with references to official docs: + +Rationale: Many users deploy on cloud platforms. Providing cloud-specific guidance helps users avoid common pitfalls (e.g., ALB session affinity for WebSocket). Keep it brief since cloud providers update their UIs frequently. + +### Chained Proxy Pattern + +Documented Cloudflare + nginx pattern: + +```nginx +set_real_ip_from 173.245.48.0/20; # Cloudflare IP ranges +real_ip_header CF-Connecting-IP; +proxy_set_header X-Forwarded-Proto https; # Force HTTPS +``` + +Rationale: Common deployment pattern (Cloudflare for DDoS protection + nginx for custom routing). Headers must propagate correctly through the chain. + +## Implementation Highlights + +### Mermaid Diagram for Architecture + +```mermaid +graph LR + A[Client Browser] -->|HTTPS| B[Reverse Proxy
nginx/Caddy] + B -->|HTTP/WebSocket| C[opencode Server
localhost:3000] + C -->|User Shell| D[PTY Sessions] +``` + +Simple visual representation helps users understand the proxy architecture. + +### Dual-Format Configuration Pattern + +Each configuration section has two versions: + +1. **Quick Start**: Minimal config for copy-paste +2. **Annotated Version**: Same config with inline comments explaining each directive + +Example: + +```nginx +# Quick Start +server { + listen 80; + server_name ; + location / { + proxy_pass http://localhost:; + # ... config + } +} + +# Annotated Version +server { + listen 80; # Listen on HTTP port 80 + server_name ; # Your domain name + location / { + proxy_pass http://localhost:; # Forward to opencode + # ... config with explanations + } +} +``` + +Rationale: Beginners can copy-paste the quick start and get working. Advanced users can read annotations to understand and customize. + +### Placeholder Consistency + +Used `` and `` throughout all examples: + +Rationale: Consistent placeholders are easier to find-and-replace. Angle brackets make them visually distinct from actual configuration syntax. + +### Let's Encrypt Integration + +Documented certbot automatic setup: + +```bash +sudo certbot --nginx -d +``` + +Rationale: Certbot automatically modifies nginx config to enable HTTPS. Users get a working HTTPS setup in one command. + +### Local Development Guidance + +Separate section for localhost development: + +- No HTTPS required (opencode auto-detects localhost) +- No trustProxy needed (direct connection) +- Security warning for LAN access + +Rationale: Developers need to run opencode without reverse proxy.

Cookie Not Deleted on Invalid Session + **What goes wrong:** User sees "session expired" but cookie remains, causing redirect loops **Why it happens:** Forget to delete cookie when session is invalid **How to avoid:** Always call deleteCookie when session validation fails **Warning signs:** Users stuck in redirect loops or seeing stale session data ### Pitfall 2: Timeout Calculated Against Creation Time Instead of Last Access + **What goes wrong:** Sessions expire based on when created, not when last used **Why it happens:** Confusing "idle timeout" with "absolute timeout" **How to avoid:** Update `lastAccessTime` on every authenticated request; compare against that **Warning signs:** Active users getting logged out; timeout doesn't "reset" on activity ### Pitfall 3: Secure Cookie on HTTP Development + **What goes wrong:** Cookies not set in local development (http://localhost) **Why it happens:** Setting `secure: true` unconditionally **How to avoid:** Only set `secure: true` when URL starts with https:// **Warning signs:** Sessions work in production but not locally; cookie never appears ### Pitfall 4: Multiple Sessions Not Tracked Properly + **What goes wrong:** "Logout everywhere" misses some sessions **Why it happens:** Not indexing sessions by username **How to avoid:** Either maintain a secondary index or iterate all sessions **Warning signs:** User logs out everywhere but other tabs still work ### Pitfall 5: Race Condition in Session Touch + **What goes wrong:** Concurrent requests cause inconsistent lastAccessTime **Why it happens:** Read-modify-write without synchronization **How to avoid:** For in-memory Map, JavaScript is single-threaded so direct assignment is safe **Warning signs:** Not applicable to this implementation (Map operations are atomic) ### Pitfall 6: Cookie Path Mismatch on Delete + **What goes wrong:** deleteCookie doesn't actually delete the cookie **Why it happens:** Must specify same path used when setting

No heap allocation, no locks. **Warning signs:** Intermittent hangs, zombie processes ### Pitfall 3: File Descriptor Leaks + **What goes wrong:** FDs accumulate, hit ulimit, security issue (fd accessible to wrong process) **Why it happens:** Not closing fds in parent after fork, not setting CLOEXEC **How to avoid:** + - Close slave fd in parent immediately after fork - Set CLOEXEC on master fd - Use OwnedFd to auto-close on drop -**Warning signs:** `lsof` shows many open fds, "too many open files" errors + **Warning signs:** `lsof` shows many open fds, "too many open files" errors ### Pitfall 4: SIGCHLD Handling Conflicts + **What goes wrong:** Child process exit not detected, zombies accumulate **Why it happens:** Tokio's signal handling conflicts with manual SIGCHLD handling **How to avoid:** Use tokio::process::Child which integrates with Tokio's signal handling **Warning signs:** `ps aux | grep defunct` shows zombie processes ### Pitfall 5: Platform-Specific TIOCSCTTY + **What goes wrong:** Controlling terminal not set on macOS **Why it happens:** TIOCSCTTY constant differs between Linux (0x540E) and macOS (0x20007461) **How to avoid:** Use cfg(target_os) for correct constant, or use nix crate's abstraction **Warning signs:** Job control (Ctrl+C, Ctrl+Z) doesn't work in spawned shell ### Pitfall 6: Missing PATH in Environment + **What goes wrong:** Commands not found in spawned shell **Why it happens:** env_clear() removes PATH, manual PATH doesn't include expected dirs **How to avoid:** Source login profile or set sensible default PATH including /usr/local/bin:/usr/bin:/bin @@ -285,6 +304,7 @@ Problems that look simple but have existing solutions: Verified patterns from official sources: ### SCM_RIGHTS with nix crate + ```rust // Source: https://docs.rs/nix/latest/nix/sys/socket/enum.ControlMessage.html use nix::sys::socket::{sendmsg, ControlMessage, MsgFlags};
