v22.1.0

Replaced legacy route-validators.ts with a unified route-validator.ts that provides a class-based RouteValidator plus the previous functional API (isValidPort, isValidDomain, validateRouteMatch, validateRouteAction, validateRouteConfig, validateRoutes, hasRequiredPropertiesForAction, assertValidRoute) for backwards compatibility. Updated utils exports and all imports/tests to reference the new module. Also switched static file loading in certificate manager to use SmartFileFactory.nodeFs(), and added @push.rocks/smartserve to devDependencies.

 # Changelog
 
+## 2025-12-09 - 22.1.0 - feat(smart-proxy)
+Improve connection/rate-limit atomicity, SNI parsing, HttpProxy & ACME orchestration, and routing utilities
+
+- Fix race conditions for per-IP connection limits by introducing atomic validate-and-track flow (SecurityManager.validateAndTrackIP) and propagating connectionId for atomic tracking.
+- Add connection-manager createConnection options (connectionId, skipIpTracking) and avoid double-tracking IPs when validated atomically.
+- RouteConnectionHandler now generates connection IDs earlier and uses atomic IP validation to prevent concurrent connection bypasses; cleans up IP tracking on global-limit rejects.
+- Enhanced TLS SNI extraction and ClientHello parsing: robust fragmented ClientHello handling, PSK-based SNI extraction for TLS 1.3 resumption, tab-reactivation heuristics and improved logging (new client-hello-parser and sni-extraction modules).
+- HttpProxy integration improvements: HttpProxyBridge initialized/synced from SmartProxy, forwardToHttpProxy forwards initial data and preserves client IP via CLIENT_IP header, robust handling of client disconnects during setup.
+- Certificate manager (SmartCertManager) improvements: better ACME initialization sequence (deferred provisioning until ports are bound), improved challenge route add/remove handling, custom certificate provisioning hook, expiry handling fallback behavior and safer error messages for port conflicts.
+- Route/port orchestration refactor (RouteOrchestrator): port usage mapping, safer add/remove port sequences, NFTables route lifecycle updates and certificate manager recreation on route changes.
+- PortManager now refcounts ports and reuses existing listeners instead of rebinding; provides helpers to add/remove/update multiple ports and improved error handling for EADDRINUSE.
+- Connection cleanup, inactivity and zombie detection hardened: batched cleanup queue, optimized inactivity checks, half-zombie detection and safer shutdown workflows.
+- Metrics, routing helpers and validators: SharedRouteManager exposes expandPortRange/getListeningPorts, route helpers add convenience HTTPS/redirect/loadbalancer builders, route-validator domain rules relaxed to allow 'localhost', '*' and IPs, and tests updated accordingly.
+- Tests updated to reflect behavioral changes (connection limit checks adapted to detect closed/ reset connections, HttpProxy integration test skipped in unit suite to avoid complex TLS setup).
+
+## 2025-12-09 - 22.0.0 - BREAKING CHANGE(smart-proxy/utils/route-validator)
+Consolidate and refactor route validators; move to class-based API and update usages
+
+Replaced legacy route-validators.ts with a unified route-validator.ts that provides a class-based RouteValidator plus the previous functional API (isValidPort, isValidDomain, validateRouteMatch, validateRouteAction, validateRouteConfig, validateRoutes, hasRequiredPropertiesForAction, assertValidRoute) for backwards compatibility. Updated utils exports and all imports/tests to reference the new module. Also switched static file loading in certificate manager to use SmartFileFactory.nodeFs(), and added @push.rocks/smartserve to devDependencies.
+
+- Rename and consolidate validator module: route-validators.ts removed; route-validator.ts added with RouteValidator class and duplicated functional API for compatibility.
+- Updated exports in ts/proxies/smart-proxy/utils/index.ts and all internal imports/tests to reference './route-validator.js' instead of './route-validators.js'.
+- Certificate manager now uses plugins.smartfile.SmartFileFactory.nodeFs() to load key/cert files (safer factory usage instead of direct static calls).
+- Added @push.rocks/smartserve to devDependencies in package.json.
+- Because the validator filename and some import paths changed, this is a breaking change for consumers importing the old module path.
+
+## 2025-08-19 - 21.1.7 - fix(route-validator)
+Relax domain validation to accept 'localhost', prefix wildcards (e.g. *example.com) and IP literals; add comprehensive domain validation tests
+
+- Allow 'localhost' as a valid domain pattern in route validation
+- Support prefix wildcard patterns like '*example.com' in addition to '*.example.com'
+- Accept IPv4 and IPv6 literal addresses in domain validation
+- Add test coverage: new test/test.domain-validation.ts with many real-world and edge-case patterns
+
 ## 2025-08-19 - 21.1.6 - fix(ip-utils)
 Fix IP wildcard/shorthand handling and add validation test

+
+## HTTPS/TLS Configuration Guide
+
+SmartProxy supports three TLS modes for handling HTTPS traffic. Understanding when to use each mode is crucial for correct configuration.
+
+### TLS Mode: Passthrough (SNI Routing)
+
+**When to use**: Backend server handles its own TLS certificates.
+
+**How it works**:
+1. Client connects with TLS ClientHello containing SNI (Server Name Indication)
+2. SmartProxy extracts the SNI hostname without decrypting
+3. Connection is forwarded to backend as-is (still encrypted)
+4. Backend server terminates TLS with its own certificate
+
+**Configuration**:
+```typescript
+{
+  match: { ports: 443, domains: 'backend.example.com' },
+  action: {
+    type: 'forward',
+    targets: [{ host: 'backend-server', port: 443 }],
+    tls: { mode: 'passthrough' }
+  }
+}
+```
+
+**Requirements**:
+- Backend must have valid TLS certificate for the domain
+- Client's SNI must be present (session tickets without SNI will be rejected)
+- No HTTP-level inspection possible (encrypted end-to-end)
+
+### TLS Mode: Terminate
+
+**When to use**: SmartProxy handles TLS, backend receives plain HTTP.
+
+**How it works**:
+1. Client connects with TLS ClientHello
+2. SmartProxy terminates TLS (decrypts traffic)
+3. Decrypted HTTP is forwarded to backend on plain HTTP port
+4. Backend receives unencrypted traffic
+
+**Configuration**:
+```typescript
+{
+  match: { ports: 443, domains: 'api.example.com' },
+  action: {
+    type: 'forward',
+    targets: [{ host: 'localhost', port: 8080 }],  // HTTP backend
+    tls: {
+      mode: 'terminate',
+      certificate: 'auto'  // Let's Encrypt, or provide { key, cert }
+    }
+  }
+}
+```
+
+**Requirements**:
+- ACME email configured for auto certificates: `acme: { email: 'admin@example.com' }`
+- Port 80 available for HTTP-01 challenges (or use DNS-01)
+- Backend accessible on HTTP port
+
+### TLS Mode: Terminate and Re-encrypt
+
+**When to use**: SmartProxy handles client TLS, but backend also requires TLS.
+
+**How it works**:
+1. Client connects with TLS ClientHello
+2. SmartProxy terminates client TLS (decrypts)
+3. SmartProxy creates new TLS connection to backend
+4. Traffic is re-encrypted for the backend connection
+
+**Configuration**:
+```typescript
+{
+  match: { ports: 443, domains: 'secure.example.com' },
+  action: {
+    type: 'forward',
+    targets: [{ host: 'backend-tls', port: 443 }],  // HTTPS backend
+    tls: {
+      mode: 'terminate-and-reencrypt',
+      certificate: 'auto'
+    }
+  }
+}
+```
+
+**Requirements**:
+- Same as 'terminate' mode
+- Backend must have valid TLS (can be self-signed for internal use)
+
+### HttpProxy Integration
+
+For TLS termination modes (`terminate` and `terminate-and-reencrypt`), SmartProxy uses an internal HttpProxy component:
+
+- HttpProxy listens on an internal port (default: 8443)
+- SmartProxy forwards TLS connections to HttpProxy for termination
+- Client IP is preserved via `CLIENT_IP:` header protocol
+- HTTP/2 and WebSocket are supported after TLS termination
+
+**Configuration**:
+```typescript
+{
+  useHttpProxy: [443],        // Ports that use HttpProxy for TLS termination
+  httpProxyPort: 8443,        // Internal HttpProxy port
+  acme: {
+    email: 'admin@example.com',
+    useProduction: true       // false for Let's Encrypt staging
+  }
+}
+```
+
+### Common Configuration Patterns
+
+**HTTP to HTTPS Redirect**:
+```typescript
+import { createHttpToHttpsRedirect } from '@push.rocks/smartproxy';
+
+const redirectRoute = createHttpToHttpsRedirect(['example.com', 'www.example.com']);
+```
+
+**Complete HTTPS Server (with redirect)**:
+```typescript
+import { createCompleteHttpsServer } from '@push.rocks/smartproxy';
+
+const routes = createCompleteHttpsServer(
+  'example.com',
+  { host: 'localhost', port: 8080 },
+  { certificate: 'auto' }
+);
+```
+
+**Load Balancer with Health Checks**:
+```typescript
+import { createLoadBalancerRoute } from '@push.rocks/smartproxy';
+
+const lbRoute = createLoadBalancerRoute(
+  'api.example.com',
+  [
+    { host: 'backend1', port: 8080 },
+    { host: 'backend2', port: 8080 },
+    { host: 'backend3', port: 8080 }
+  ],
+  { tls: { mode: 'terminate', certificate: 'auto' } }
+);
+```
+
+### Troubleshooting
+
+**"No SNI detected" errors**:
+- Client is using TLS session resumption without SNI
+- Solution: Configure route for TLS termination (allows session resumption)
+
+**"HttpProxy not available" errors**:
+- `useHttpProxy` not configured for the port
+- Solution: Add port to `useHttpProxy` array in settings
+
+**Certificate provisioning failures**:
+- Port 80 not accessible for HTTP-01 challenges
+- ACME email not configured
+- Solution: Ensure port 80 is available and `acme.email` is set
+
+**Connection timeouts to HttpProxy**:
+- CLIENT_IP header parsing timeout (default: 2000ms)
+- Network congestion between SmartProxy and HttpProxy
+- Solution: Check localhost connectivity, increase timeout if needed
