c4b9d7eb72 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.

# Changelog
## 2025-12-09 - 22.1.1 - fix(tests)
Normalize route configurations in tests to use name (remove id) and standardize route names
- Removed deprecated id properties from route configurations in multiple tests and rely on the name property instead
- Standardized route.name values to kebab-case / lowercase (examples: 'tcp-forward', 'tls-passthrough', 'domain-a', 'domain-b', 'test-forward', 'nftables-test', 'regular-test', 'forward-test', 'test-forward', 'tls-test')
- Added explicit names for inner and outer proxies in proxy-chain-cleanup test ('inner-backend', 'outer-frontend')
- Updated certificate metadata timestamps in certs/static-route/meta.json
## 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
- Support shorthand IPv4 wildcard patterns (e.g. '10.*', '192.168.*') by expanding them to full 4-octet patterns before matching
- Normalize and expand patterns in IpUtils.isGlobIPMatch and SharedSecurityManager IP checks to ensure consistent minimatch comparisons
- Relax route validator wildcard checks to accept 1-4 octet wildcard specifications for IPv4 patterns
- Add test harness test-ip-validation.ts to exercise common wildcard/shorthand IP patterns
## 2025-08-19 - 21.1.5 - fix(core)
Prepare patch release: documentation, tests and stability fixes (metrics, ACME, connection cleanup)
- Byte counting and throughput: per-route and per-IP throughput trackers with per-second sampling; removed double-counting and improved sampling buffers for accurate rates
- HttpProxy and forwarding: Ensure metricsCollector.recordBytes() is called in forwarding paths so throughput is recorded reliably
- ACME / Certificate Manager: support for custom certProvisionFunction with configurable fallback to ACME (http01) and improved challenge route lifecycle
- Connection lifecycle and cleanup: improved lifecycle component timer/listener cleanup, better cleanup queue batching and zombie/half-zombie detection
- Various utilities and stability improvements: enhanced IP utils, path/domain matching improvements, safer socket handling and more robust fragment/ClientHello handling
- Tests and docs: many test files and readme.hints.md updated with byte-counting audit, connection cleanup and ACME guidance
## 2025-08-14 - 21.1.4 - fix(security)
Critical security and stability fixes
- Fixed critical socket.emit override vulnerability that was breaking TLS connections
- Implemented comprehensive socket cleanup with new socket tracker utility
- Improved code organization by extracting RouteOrchestrator from SmartProxy
- Fixed IPv6 loopback detection for proper IPv6 support
- Added memory bounds to prevent unbounded collection growth
- Fixed certificate manager race conditions with proper synchronization
- Unreferenced long-lived timers to prevent process hanging
- Enhanced route validation for socket-handler actions
- Fixed header parsing when extractFullHeaders option is enabled
## 2025-07-22 - 21.1.1 - fix(detection)
Fix SNI detection in TLS detector
- Restored proper TLS detector implementation with ClientHello parsing
- Fixed imports to use new protocols module locations
- Added missing detectWithContext method for fragmented detection
- Fixed method names to match BufferAccumulator interface
- Removed unused import readUInt24BE
## 2025-07-21 - 21.1.0 - feat(protocols)
Refactor protocol utilities into centralized protocols module

## 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
