# SmartProxy Byte Counting Audit Report
## Executive Summary
After a comprehensive audit of the SmartProxy codebase, I can confirm that **byte counting is implemented correctly** with no instances of double counting. Each byte transferred through the proxy is counted exactly once in each direction.
## Byte Counting Implementation
### 1. Core Tracking Mechanisms
SmartProxy uses two complementary tracking systems:
1. **Connection Records** (`IConnectionRecord`):
- `bytesReceived`: Total bytes received from client
- `bytesSent`: Total bytes sent to client
2. **MetricsCollector**:
- Global throughput tracking via `ThroughputTracker`
- Per-connection byte tracking for route/IP metrics
- Called via `recordBytes(connectionId, bytesIn, bytesOut)`
### 2. Where Bytes Are Counted
Bytes are counted in only two files:
#### a) `route-connection-handler.ts`
- **Line 351**: TLS alert bytes when no SNI is provided
- **Lines 1286-1301**: Data forwarding callbacks in `setupBidirectionalForwarding()`
#### b) `http-proxy-bridge.ts`
- **Line 127**: Initial TLS chunk for HttpProxy connections
- **Lines 142-154**: Data forwarding callbacks in `setupBidirectionalForwarding()`
## Connection Flow Analysis
### 1. Direct TCP Connection (No TLS)
```
Client → SmartProxy → Target Server
```
1. Connection arrives at `RouteConnectionHandler.handleConnection()`
2. For non-TLS ports, immediately routes via `routeConnection()`
3. `setupDirectConnection()` creates target connection
4. `setupBidirectionalForwarding()` handles all data transfer:
- `onClientData`: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
- `onServerData`: `bytesSent += chunk.length` + `recordBytes(0, chunk.length)`
**Result**: ✅ Each byte counted exactly once
### 2. TLS Passthrough Connection
```
Client (TLS) → SmartProxy → Target Server (TLS)
```
1. Connection waits for initial data to detect TLS
2. TLS handshake detected, SNI extracted
3. Route matched, `setupDirectConnection()` called
4. Initial chunk stored in `pendingData` (NOT counted yet)
5. On target connect, `pendingData` written to target (still not counted)
6. `setupBidirectionalForwarding()` counts ALL bytes including initial chunk
**Result**: ✅ Each byte counted exactly once
### 3. TLS Termination via HttpProxy
```
Client (TLS) → SmartProxy → HttpProxy (localhost) → Target Server
```
1. TLS connection detected with `tls.mode = "terminate"`
2. `forwardToHttpProxy()` called:
- Initial chunk: `bytesReceived += chunk.length` + `recordBytes(chunk.length, 0)`
3. Proxy connection created to HttpProxy on localhost
4. `setupBidirectionalForwarding()` handles subsequent data
**Result**: ✅ Each byte counted exactly once
### 4. HTTP Connection via HttpProxy
```
Client (HTTP) → SmartProxy → HttpProxy (localhost) → Target Server
```
1. Connection on configured HTTP port (`useHttpProxy` ports)
2. Same flow as TLS termination
3. All byte counting identical to TLS termination
**Result**: ✅ Each byte counted exactly once
### 5. NFTables Forwarding
```
Client → [Kernel NFTables] → Target Server
```
1. Connection detected, route matched with `forwardingEngine: 'nftables'`
2. Connection marked as `usingNetworkProxy = true`
3. NO application-level forwarding (kernel handles packet routing)
4. NO byte counting in application layer
**Result**: ✅ No counting (correct - kernel handles everything)
## Special Cases
### PROXY Protocol
- PROXY protocol headers sent to backend servers are NOT counted in client metrics
- Only actual client data is counted
- **Correct behavior**: Protocol overhead is not client data
### TLS Alerts
- TLS alerts (e.g., for missing SNI) are counted as sent bytes
- **Correct behavior**: Alerts are actual data sent to the client
### Initial Chunks
- **Direct connections**: Stored in `pendingData`, counted when forwarded
- **HttpProxy connections**: Counted immediately upon receipt
- **Both approaches**: Count each byte exactly once
## Verification Methodology
1. **Code Analysis**: Searched for all instances of:
- `bytesReceived +=` and `bytesSent +=`
- `recordBytes()` calls
- Data forwarding implementations
2. **Flow Tracing**: Followed data path for each connection type from entry to exit
3. **Handler Review**: Examined all forwarding handlers to ensure no additional counting
## Findings
### ✅ No Double Counting Detected
- Each byte is counted exactly once in the direction it flows
- Connection records and metrics are updated consistently
- No overlapping or duplicate counting logic found
### Areas of Excellence
1. **Centralized Counting**: All byte counting happens in just two files
2. **Consistent Pattern**: Uses `setupBidirectionalForwarding()` with callbacks
3. **Clear Separation**: Forwarding handlers don't interfere with proxy metrics
## Recommendations
1. **Debug Logging**: Add optional debug logging to verify byte counts in production:
```typescript
if (settings.debugByteCount) {
logger.log('debug', `Bytes counted: ${connectionId} +${bytes} (total: ${record.bytesReceived})`);
}
```
2. **Unit Tests**: Create specific tests to ensure byte counting accuracy:
- Test initial chunk handling
- Test PROXY protocol overhead exclusion
- Test HttpProxy forwarding accuracy
3. **Protocol Overhead Tracking**: Consider separately tracking:
- PROXY protocol headers
- TLS handshake bytes
- HTTP headers vs body
4. **NFTables Documentation**: Clearly document that NFTables-forwarded connections are not included in application metrics
## Conclusion
SmartProxy's byte counting implementation is **robust and accurate**. The design ensures that each byte is counted exactly once, with clear separation between connection tracking and metrics collection. No remediation is required.

# SmartProxy Development Hints
## Byte Tracking and Metrics
### Throughput Drift Issue (Fixed)
**Problem**: Throughput numbers were gradually increasing over time for long-lived connections.
**Root Cause**: The `byRoute()` and `byIP()` methods were dividing cumulative total bytes (since connection start) by the window duration, causing rates to appear higher as connections aged:
- Hour 1: 1GB total / 60s = 17 MB/s ✓
- Hour 2: 2GB total / 60s = 34 MB/s ✗ (appears doubled!)
- Hour 3: 3GB total / 60s = 50 MB/s ✗ (keeps rising!)
**Solution**: Implemented dedicated ThroughputTracker instances for each route and IP address:
- Each route and IP gets its own throughput tracker with per-second sampling
- Samples are taken every second and stored in a circular buffer
- Rate calculations use actual samples within the requested window
- Default window is now 1 second for real-time accuracy
### What Gets Counted (Network Interface Throughput)
The byte tracking is designed to match network interface throughput (what Unifi/network monitoring tools show):
**Counted bytes include:**
- All application data
- TLS handshakes and protocol overhead
- TLS record headers and encryption padding
- HTTP headers and protocol data
- WebSocket frames and protocol overhead
- TLS alerts sent to clients
**NOT counted:**
- PROXY protocol headers (sent to backend, not client)
- TCP/IP headers (handled by OS, not visible at application layer)
**Byte direction:**
- `bytesReceived`: All bytes received FROM the client on the incoming connection
- `bytesSent`: All bytes sent TO the client on the incoming connection
- Backend connections are separate and not mixed with client metrics
### Double Counting Issue (Fixed)
**Problem**: Initial data chunks were being counted twice in the byte tracking:
1. Once when stored in `pendingData` in `setupDirectConnection()`
2. Again when the data flowed through bidirectional forwarding
**Solution**: Removed the byte counting when storing initial chunks. Bytes are now only counted when they actually flow through the `setupBidirectionalForwarding()` callbacks.
### HttpProxy Metrics (Fixed)
**Problem**: HttpProxy forwarding was updating connection record byte counts but not calling `metricsCollector.recordBytes()`, resulting in missing throughput data.
**Solution**: Added `metricsCollector.recordBytes()` calls to the HttpProxy bidirectional forwarding callbacks.
### Metrics Architecture
The metrics system has multiple layers:
1. **Connection Records** (`record.bytesReceived/bytesSent`): Track total bytes per connection
2. **Global ThroughputTracker**: Accumulates bytes between samples for overall rate calculations
3. **Per-Route ThroughputTrackers**: Dedicated tracker for each route with per-second sampling
4. **Per-IP ThroughputTrackers**: Dedicated tracker for each IP with per-second sampling
5. **connectionByteTrackers**: Track cumulative bytes and metadata for active connections
Key features:
- All throughput trackers sample every second (1Hz)
- Each tracker maintains a circular buffer of samples (default: 1 hour retention)
- Rate calculations are accurate for any requested window (default: 1 second)
- All byte counting happens exactly once at the data flow point
- Unused route/IP trackers are automatically cleaned up when connections close
### Understanding "High" Byte Counts
If byte counts seem high compared to actual application data, remember:
- TLS handshakes can be 1-5KB depending on cipher suites and certificates
- Each TLS record has 5 bytes of header overhead
- TLS encryption adds 16-48 bytes of padding/MAC per record
- HTTP/2 has additional framing overhead
- WebSocket has frame headers (2-14 bytes per message)
This overhead is real network traffic and should be counted for accurate throughput metrics.
### Byte Counting Paths
There are two mutually exclusive paths for connections:
1. **Direct forwarding** (route-connection-handler.ts):
- Used for TCP passthrough, TLS passthrough, and direct connections
- Bytes counted in `setupBidirectionalForwarding` callbacks
- Initial chunk NOT counted separately (flows through bidirectional forwarding)
2. **HttpProxy forwarding** (http-proxy-bridge.ts):
- Used for TLS termination (terminate, terminate-and-reencrypt)
- Initial chunk counted when written to proxy
- All subsequent bytes counted in `setupBidirectionalForwarding` callbacks
- This is the ONLY counting point for these connections
### Byte Counting Audit (2025-01-06)
A comprehensive audit was performed to verify byte counting accuracy:
**Audit Results:**
- ✅ No double counting detected in any connection flow
- ✅ Each byte counted exactly once in each direction
- ✅ Connection records and metrics updated consistently
- ✅ PROXY protocol headers correctly excluded from client metrics
- ✅ NFTables forwarded connections correctly not counted (kernel handles)
**Key Implementation Points:**
- All byte counting happens in only 2 files: `route-connection-handler.ts` and `http-proxy-bridge.ts`
- Both use the same pattern: increment `record.bytesReceived/Sent` AND call `metricsCollector.recordBytes()`
- Initial chunks handled correctly: stored but not counted until forwarded
- TLS alerts counted as sent bytes (correct - they are sent to client)
For full audit details, see `readme.byte-counting-audit.md`
## Connection Cleanup
### Zombie Connection Detection
The connection manager performs comprehensive zombie detection every 10 seconds:
- **Full zombies**: Both incoming and outgoing sockets destroyed but connection not cleaned up
- **Half zombies**: One socket destroyed, grace period expired (5 minutes for TLS, 30 seconds for non-TLS)
- **Stuck connections**: Data received but none sent back after threshold (5 minutes for TLS, 60 seconds for non-TLS)
### Cleanup Queue
Connections are cleaned up through a batched queue system:
- Batch size: 100 connections
- Processing triggered immediately when batch size reached
- Otherwise processed after 100ms delay
- Prevents overwhelming the system during mass disconnections
## Keep-Alive Handling
Keep-alive connections receive special treatment based on `keepAliveTreatment` setting:
- **standard**: Normal timeout applies
- **extended**: Timeout multiplied by `keepAliveInactivityMultiplier` (default 6x)
- **immortal**: No timeout, connections persist indefinitely
## PROXY Protocol
The system supports both receiving and sending PROXY protocol:
- **Receiving**: Automatically detected from trusted proxy IPs (configured in `proxyIPs`)
- **Sending**: Enabled per-route or globally via `sendProxyProtocol` setting
- Real client IP is preserved and used for all connection tracking and security checks
## Metrics and Throughput Calculation
The metrics system tracks throughput using per-second sampling:
1. **Byte Recording**: Bytes are recorded as data flows through connections
2. **Sampling**: Every second, accumulated bytes are stored as a sample
3. **Rate Calculation**: Throughput is calculated by summing bytes over a time window
4. **Per-Route/IP Tracking**: Separate ThroughputTracker instances for each route and IP
Key implementation details:
- Bytes are recorded in the bidirectional forwarding callbacks
- The instant() method returns throughput over the last 1 second
- The recent() method returns throughput over the last 10 seconds
- Custom windows can be specified for different averaging periods
### Throughput Spikes Issue
There's a fundamental difference between application-layer and network-layer throughput:
**Application Layer (what we measure)**:
- Bytes are recorded when delivered to/from the application
- Large chunks can arrive "instantly" due to kernel/Node.js buffering
- Shows spikes when buffers are flushed (e.g., 20MB in 1 second = 160 Mbit/s)
**Network Layer (what Unifi shows)**:
- Actual packet flow through the network interface
- Limited by physical network speed (e.g., 20 Mbit/s)
- Data transfers over time, not in bursts
The spikes occur because:
1. Data flows over network at 20 Mbit/s (takes 8 seconds for 20MB)
2. Kernel/Node.js buffers this incoming data
3. When buffer is flushed, application receives large chunk at once
4. We record entire chunk in current second, creating artificial spike
**Potential Solutions**:
1. Use longer window for "instant" measurements (e.g., 5 seconds instead of 1)
2. Track socket write backpressure to estimate actual network flow
3. Implement bandwidth estimation based on connection duration
4. Accept that application-layer != network-layer throughput
## Connection Limiting
### Per-IP Connection Limits
- SmartProxy tracks connections per IP address in the SecurityManager
- Default limit is 100 connections per IP (configurable via `maxConnectionsPerIP`)
- Connection rate limiting is also enforced (default 300 connections/minute per IP)
- HttpProxy has been enhanced to also enforce per-IP limits when forwarding from SmartProxy
### Route-Level Connection Limits
- Routes can define `security.maxConnections` to limit connections per route
- ConnectionManager tracks connections by route ID using a separate Map
- Limits are enforced in RouteConnectionHandler before forwarding
- Connection is tracked when route is matched: `trackConnectionByRoute(routeId, connectionId)`
### HttpProxy Integration
- When SmartProxy forwards to HttpProxy for TLS termination, it sends a `CLIENT_IP:<ip>\r\n` header
- HttpProxy parses this header to track the real client IP, not the localhost IP
- This ensures per-IP limits are enforced even for forwarded connections
- The header is parsed in the connection handler before any data processing
### Memory Optimization
- Periodic cleanup runs every 60 seconds to remove:
- IPs with no active connections
- Expired rate limit timestamps (older than 1 minute)
- Prevents memory accumulation from many unique IPs over time
- Cleanup is automatic and runs in background with `unref()` to not keep process alive
### Connection Cleanup Queue
- Cleanup queue processes connections in batches to prevent overwhelming the system
- Race condition prevention using `isProcessingCleanup` flag
- Try-finally block ensures flag is always reset even if errors occur
- New connections added during processing are queued for next batch
### Important Implementation Notes
- Always use `NodeJS.Timeout` type instead of `NodeJS.Timer` for interval/timeout references
- IPv4/IPv6 normalization is handled (e.g., `::ffff:127.0.0.1` and `127.0.0.1` are treated as the same IP)
- Connection limits are checked before route matching to prevent DoS attacks
- SharedSecurityManager supports checking route-level limits via optional parameter
## Log Deduplication
To reduce log spam during high-traffic scenarios or attacks, SmartProxy implements log deduplication for repetitive events:
### How It Works
- Similar log events are batched and aggregated over a 5-second window
- Instead of logging each event individually, a summary is emitted
- Events are grouped by type and deduplicated by key (e.g., IP address, reason)
### Deduplicated Event Types
1. **Connection Rejections** (`connection-rejected`):
- Groups by rejection reason (global-limit, route-limit, etc.)
- Example: "Rejected 150 connections (reasons: global-limit: 100, route-limit: 50)"
2. **IP Rejections** (`ip-rejected`):
- Groups by IP address
- Shows top offenders with rejection counts and reasons
- Example: "Rejected 500 connections from 10 IPs (top offenders: 192.168.1.100 (200x, rate-limit), ...)"
3. **Connection Cleanups** (`connection-cleanup`):
- Groups by cleanup reason (normal, timeout, error, zombie, etc.)
- Example: "Cleaned up 250 connections (reasons: normal: 200, timeout: 30, error: 20)"
4. **IP Tracking Cleanup** (`ip-cleanup`):
- Summarizes periodic IP cleanup operations
- Example: "IP tracking cleanup: removed 50 entries across 5 cleanup cycles"
### Configuration
- Default flush interval: 5 seconds
- Maximum batch size: 100 events (triggers immediate flush)
- Global periodic flush: Every 10 seconds (ensures logs are emitted regularly)
- Process exit handling: Logs are flushed on SIGINT/SIGTERM
### Benefits
- Reduces log volume during attacks or high traffic
- Provides better overview of patterns (e.g., which IPs are attacking)
- Improves log readability and analysis
- Prevents log storage overflow
- Maintains detailed information in aggregated form
### Log Output Examples
Instead of hundreds of individual logs:
```
Connection rejected
Connection rejected
Connection rejected
... (repeated 500 times)
```
You'll see:
```
[SUMMARY] Rejected 500 connections from 10 IPs in 5s (rate-limit: 350, per-ip-limit: 150) (top offenders: 192.168.1.100 (200x, rate-limit), 10.0.0.1 (150x, per-ip-limit))
```
Instead of:
```
Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 266
Connection terminated: ::ffff:127.0.0.1 (client_closed). Active: 265
... (repeated 266 times)
```
You'll see:
```
[SUMMARY] 266 HttpProxy connections terminated in 5s (reasons: client_closed: 266, activeConnections: 0)
```
### Rapid Event Handling
- During attacks or high-volume scenarios, logs are flushed more frequently
- If 50+ events occur within 1 second, immediate flush is triggered
- Prevents memory buildup during flooding attacks
- Maintains real-time visibility during incidents
## Custom Certificate Provision Function
The `certProvisionFunction` feature has been implemented to allow users to provide their own certificate generation logic.
### Implementation Details
1. **Type Definition**: The function must return `Promise<TSmartProxyCertProvisionObject>` where:
- `TSmartProxyCertProvisionObject = plugins.tsclass.network.ICert | 'http01'`
- Return `'http01'` to fallback to Let's Encrypt
- Return a certificate object for custom certificates
2. **Certificate Manager Changes**:
- Added `certProvisionFunction` property to CertificateManager
- Modified `provisionAcmeCertificate()` to check custom function first
- Custom certificates are stored with source type 'custom'
- Expiry date extraction currently defaults to 90 days
3. **Configuration Options**:
- `certProvisionFunction`: The custom provision function
- `certProvisionFallbackToAcme`: Whether to fallback to ACME on error (default: true)
4. **Usage Example**:
```typescript
new SmartProxy({
certProvisionFunction: async (domain: string) => {
if (domain === 'internal.example.com') {
return {
cert: customCert,
key: customKey,
ca: customCA
} as unknown as TSmartProxyCertProvisionObject;
}
return 'http01'; // Use Let's Encrypt
},
certProvisionFallbackToAcme: true
})
```
5. **Testing Notes**:
- Type assertions through `unknown` are needed in tests due to strict interface typing
- Mock certificate objects work for testing but need proper type casting
- The actual certificate parsing for expiry dates would need a proper X.509 parser
### Future Improvements
1. Implement proper certificate expiry date extraction using X.509 parsing
2. Add support for returning expiry date with custom certificates
3. Consider adding validation for custom certificate format
4. Add events/hooks for certificate provisioning lifecycle

# SmartProxy Enhanced Routing Plan
## Goal
Implement enhanced routing structure with multiple targets per route, sub-matching capabilities, and target-specific overrides to enable more elegant and DRY configurations.
## Key Changes
### 1. Update Route Target Interface
- Add `match` property to `IRouteTarget` for sub-matching within routes
- Add target-specific override properties (tls, websocket, loadBalancing, etc.)
- Add priority field for controlling match order
### 2. Update Route Action Interface
- Remove singular `target` property
- Use only `targets` array (single target = array with one element)
- Maintain backwards compatibility during migration
### 3. Implementation Steps
#### Phase 1: Type Updates
- [x] Update `IRouteTarget` interface in `route-types.ts`
- Add `match?: ITargetMatch` property
- Add override properties (tls, websocket, etc.)
- Add `priority?: number` field
- [x] Create `ITargetMatch` interface for sub-matching criteria
- [x] Update `IRouteAction` to use only `targets: IRouteTarget[]`
#### Phase 2: Route Resolution Logic
- [x] Update route matching logic to handle multiple targets
- [x] Implement target sub-matching algorithm:
1. Sort targets by priority (highest first)
2. For each target with a match property, check if request matches
3. Use first matching target, or fallback to target without match
- [x] Ensure target-specific settings override route-level settings
#### Phase 3: Code Migration
- [x] Find all occurrences of `action.target` and update to use `action.targets`
- [x] Update route helpers and utilities
- [x] Update certificate manager to handle multiple targets
- [x] Update connection handlers
#### Phase 4: Testing
- [x] Update existing tests to use new format
- [ ] Add tests for multi-target scenarios
- [ ] Add tests for sub-matching logic
- [ ] Add tests for setting overrides
#### Phase 5: Documentation
- [ ] Update type documentation
- [ ] Add examples of new routing patterns
- [ ] Document migration path for existing configs
## Example Configurations
### Before (Current)
```typescript
// Need separate routes for different ports/paths
[
{
match: { domains: ['api.example.com'], ports: [80] },
action: {
type: 'forward',
target: { host: 'backend', port: 8080 },
tls: { mode: 'terminate' }
}
},
{
match: { domains: ['api.example.com'], ports: [443] },
action: {
type: 'forward',
target: { host: 'backend', port: 8081 },
tls: { mode: 'passthrough' }
}
}
]
```
### After (Enhanced)
```typescript
// Single route with multiple targets
{
match: { domains: ['api.example.com'], ports: [80, 443] },
action: {
type: 'forward',
targets: [
{
match: { ports: [80] },
host: 'backend',
port: 8080,
tls: { mode: 'terminate' }
},
{
match: { ports: [443] },
host: 'backend',
port: 8081,
tls: { mode: 'passthrough' }
}
]
}
}
```
### Advanced Example
```typescript
{
match: { domains: ['app.example.com'], ports: [443] },
action: {
type: 'forward',
tls: { mode: 'terminate', certificate: 'auto' }, // Route-level default
websocket: { enabled: true }, // Route-level default
targets: [
{
match: { path: '/api/v2/*' },
host: 'api-v2',
port: 8082,
priority: 10
},
{
match: { path: '/api/*', headers: { 'X-Version': 'v1' } },
host: 'api-v1',
port: 8081,
priority: 5
},
{
match: { path: '/ws/*' },
host: 'websocket-server',
port: 8090,
websocket: {
enabled: true,
rewritePath: '/' // Strip /ws prefix
}
},
{
// Default target (no match property)
host: 'web-backend',
port: 8080
}
]
}
}
```
## Benefits
1. **DRY Configuration**: No need to duplicate common settings across routes
2. **Flexibility**: Different backends for different ports/paths within same domain
3. **Clarity**: All routing for a domain in one place
4. **Performance**: Single route lookup instead of multiple
5. **Backwards Compatible**: Can migrate gradually
## Migration Strategy
1. Keep support for `target` temporarily with deprecation warning
2. Auto-convert `target` to `targets: [target]` internally
3. Update documentation with migration examples
4. Remove `target` support in next major version
