management systems. - -## Overview - -This module provides a unified interface for overriding system DNS servers on: -- **macOS**: Using `scutil` -- **Windows**: Using Windows Registry -- **Linux/FreeBSD**: Supporting multiple backends: - - systemd-resolved (D-Bus) - - NetworkManager (D-Bus) - - resolvconf utility - - Direct `/etc/resolv.conf` manipulation - -## Features - -- ✅ Cross-platform DNS override -- ✅ Automatic detection of best DNS management method -- ✅ Backup and restore original DNS settings -- ✅ Platform-specific optimizations -- ✅ No external dependencies for basic functionality - -## Architecture - -### Interface - -All configurators implement the `DNSConfigurator` interface: - -```go -type DNSConfigurator interface { - SetDNS(servers []netip.Addr) ([]netip.Addr, error) - RestoreDNS() error - GetCurrentDNS() ([]netip.Addr, error) - Name() string -} -``` - -### Platform-Specific Implementations - -Each platform has dedicated structs instead of using build tags at the file level: - -- `DarwinDNSConfigurator` - macOS using scutil -- `WindowsDNSConfigurator` - Windows using registry -- `FileDNSConfigurator` - Unix using /etc/resolv.conf -- `SystemdResolvedDNSConfigurator` - Linux using systemd-resolved -- `NetworkManagerDNSConfigurator` - Linux using NetworkManager -- `ResolvconfDNSConfigurator` - Linux using resolvconf utility - -## Usage - -### Automatic Detection - -```go -import "github.com/your-org/olm/dns/platform" - -// On Linux/Unix - provide interface name for best results -configurator, err :=

DNS settings are applied via the Network Service state hierarchy. - -**Pros:** -- Native macOS API -- Proper integration with system preferences -- Supports DNS flushing - -**Cons:** -- Requires elevated privileges - -### Windows - -Modifies registry keys under `SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\{GUID}`. - -**Pros:** -- Direct registry manipulation -- Immediate effect after cache flush - -**Cons:** -- Requires interface GUID -- Requires administrator privileges -- May require restart of DNS client service - -### Linux: systemd-resolved - -Uses D-Bus API to communicate with systemd-resolved service. - -**Pros:** -- Modern standard on many distributions -- Proper per-interface configuration -- No file manipulation needed - -**Cons:** -- Requires D-Bus access -- Only available on systemd systems -- Interface-specific - -### Linux: NetworkManager - -Uses D-Bus API to modify NetworkManager connection settings. - -**Pros:** -- Common on desktop Linux -- Integrates with NetworkManager GUI -- Per-interface configuration - -**Cons:** -- Requires NetworkManager to be running -- D-Bus access required -- Interface-specific - -### Linux: resolvconf - -Uses the `resolvconf` utility to update DNS configuration. - -**Pros:** -- Works on many different systems -- Handles merging of multiple DNS sources -- Supports both openresolv and Debian resolvconf - -**Cons:** -- Requires resolvconf to be installed -- Interface-specific - -### Linux: Direct File - -Directly modifies `/etc/resolv.conf` with backup. - -**Pros:** -- Works everywhere -- No dependencies -- Simple and reliable - -**Cons:** -- May be overwritten by DHCP or other services -- No per-interface configuration -- Doesn't integrate with system tools - -## Build Tags - -The module uses build tags to compile platform-specific code: - -- `//go:build darwin && !ios` - macOS (non-iOS) -- `//go:build windows` - Windows -- `//go:build (linux && !android) || freebsd` - Linux and FreeBSD -- `//go:build linux && !android` - Linux only (for systemd) - -## Dependencies - -- `github.com/godbus/dbus/v5` - D-Bus communication (Linux only) -- `golang.org/x/sys` - System calls and registry access -- Standard library - -## Security Considerations - -- **Elevated Privileges**: Most DNS modification operations require root/administrator privileges -- **Backup Files**: Backup files contain original DNS configuration and should be protected -- **State Persistence**: DNS state is stored in memory; unexpected termination may require manual cleanup - -## Cleanup - -The module properly cleans up after itself: - -1. Backup files are created before modification -2. Original DNS servers are stored in memory -3. `RestoreDNS()` should be called to restore original settings -4. On Linux file-based systems, backup files are removed after restoration - -## Testing - -Each configurator can be tested independently: - -```go -func TestDNSOverride(t *testing.T) { - configurator, err := platform.NewFileDNSConfigurator() - require.NoError(t, err) - - servers := []netip.Addr{ - netip.MustParseAddr("1.1.1.1"), - } - - original, err := configurator.SetDNS(servers) - require.NoError(t, err) - - defer configurator.RestoreDNS() -

-### Files Removed - -**Old NetBird-specific files:** -- `dbus_unix.go` - D-Bus utilities (functionality moved into platform-specific files) -- `file_parser_unix.go` - resolv.conf parser (simplified and integrated into file.go) -- `file_repair_unix.go` - File watching/repair (removed - out of scope) -- `file_unix.go` - Old file configurator (replaced by file.go) -- `host_darwin.go` - Old macOS configurator (replaced by darwin.go) -- `host_unix.go` - Old Unix manager factory (replaced by detect_unix.go) -- `host_windows.go` -

Old systemd-resolved (replaced by systemd.go) -- `unclean_shutdown_*.go` - Unclean shutdown detection (removed - out of scope) - -### Key Architectural Changes - -1. **Removed Build Tags for Platform Selection** - - Old: Used `//go:build` tags at top of files to compile different code per platform - - New: Named structs differently per platform (e.g., `DarwinDNSConfigurator`, `WindowsDNSConfigurator`) - - Build tags kept only where necessary for cross-platform library imports - -2. **Simplified Interface** - - Removed complex domain routing, search domains, and port customization - - Focused on core functionality: Set DNS, Get DNS, Restore DNS - - Removed state manager dependencies - -3. **Removed External Dependencies** - - Removed: statemanager, NetBird-specific types, logging libraries - - Kept only: D-Bus (for Linux), x/sys (for Windows registry and Unix syscalls) - - Uses standard library where possible - -4. **Standalone Operation** - - No longer depends on NetBird types (HostDNSConfig, etc.) - - Uses standard library types (net/netip.Addr) - - Self-contained backup/restore logic - -5. **Improved Code Organization** - - Each platform has its own clearly-named file - - Detection logic separated into detect_*.go files - - Shared types in types.go - - Examples in dedicated examples/ directory - -### Feature Comparison - -**Removed (out of scope for basic DNS override):** -- Search domain management -- Match-only domains -- DNS port customization (except where natively supported) -- File watching and auto-repair -- Unclean shutdown detection -- State persistence -- Integration with external state managers - -**Retained (core DNS functionality):** -- Setting DNS servers -- Getting current DNS servers -- Restoring original DNS servers -- Automatic platform detection -- DNS cache flushing -- Backup and restore of original configuration - -### Platform-Specific Notes - -**macOS (Darwin):** -- Simplified to focus on DNS server override using scutil -- Removed complex domain routing and local DNS setup -- Removed GPO and state management -- Kept DNS cache flushing - -**Windows:** -- Simplified registry manipulation to just NameServer key -- Removed NRPT (Name Resolution Policy Table) support -- Removed DNS registration and WINS management -- Kept DNS cache flushing - -**Linux - File-based:** -- Direct /etc/resolv.conf manipulation with backup -- Removed file watching and auto-repair -- Removed complex search domain merging logic -- Simple nameserver-only configuration - -**Linux - systemd-resolved:** -- D-Bus API for per-link DNS configuration -- Simplified to just DNS server setting -- Uses Revert method for restoration - -**Linux - NetworkManager:** -- D-Bus API for connection settings modification -- Simplified to IPv4 DNS only -- Removed search/match domain complexity - -**Linux - resolvconf:** -- Uses resolvconf utility (openresolv or Debian resolvconf) -- Interface-specific configuration -- Simple nameserver configuration - -### Usage Pattern - -```go -// Automatic detection -configurator, err := platform.DetectBestConfigurator("eth0") - -// Set DNS -original, err := configurator.SetDNS([]netip.Addr{ - netip.MustParseAddr("8.8.8.8"), -}) - -// Restore -defer configurator.RestoreDNS() -``` - -### Maintenance Notes - -- Each platform implementation is independent -- No shared state between configurators -- Backups are file-based or in-memory only -- No external database or state management required -- Configurators can be tested independently - -## Migration Guide - -If you were using the old code: - -1. Replace `HostDNSConfig` with simple `[]netip.Addr` for DNS servers -2. Replace `newHostManager()` with `platform.DetectBestConfigurator()` -3. Replace `applyDNSConfig()` with `SetDNS()` -4. Replace `restoreHostDNS()` with `RestoreDNS()` -5. Remove state manager dependencies -6.

Write responses back to the TUN device - -Example: - -```go -// In your service -func (s *MyService) handlePacket(packet []byte) bool { - // Parse packet - // Process request - // Write response to TUN device - s.tunDevice.Write([][]byte{response}, 0) - return true // Drop from normal path -} - -// During initialization -filteredDev.AddRule(myServiceIP, myService.handlePacket) -``` - -### Adding Filtering Rules - -Rules can be added/removed dynamically: - -```go -// Add a rule -filteredDev.AddRule(netip.MustParseAddr("10.30.30.40"), handleSpecialIP) - -// Remove a rule -filteredDev.RemoveRule(netip.MustParseAddr("10.30.30.40")) -``` - -## Implementation Details - -### Why Direct TUN Write? - -The DNS proxy writes responses directly back to the TUN device instead of going through the filter because: -1. Responses should go to the host, not through WireGuard -2. Avoids infinite loops (response → filter → DNS proxy → ...) -3. Better performance (one less layer) - -### Thread Safety - -- `FilteredDevice` uses RWMutex for rule access (read-heavy workload) -- `DNSProxy` goroutines are properly synchronized -- TUN device write operations are thread-safe - -### Error Handling - -- Failed DNS queries fall back to secondary DNS server -- Malformed packets are logged but don't crash the proxy -- Context cancellation ensures clean shutdown - -## Future Enhancements - -Potential improvements: -1. DNS caching to reduce upstream queries -2. DNS-over-HTTPS (DoH) support -3. Custom DNS filtering/blocking -4. Metrics and monitoring -5. IPv6 support for DNS proxy -6.

The implementation consists of three main components: - -### 1. FilteredDevice (`olm/device_filter.go`) -A TUN device wrapper that provides fast packet filtering: -- **Performance**: 2.6 ns per packet inspection (benchmarked) -- **Zero overhead** for non-matching packets -- **Extensible**: Easy to add new filter rules for other services -- **Thread-safe**: Uses RWMutex for concurrent access - -Key features: -- Fast destination IP extraction (IPv4 and IPv6) -- Protocol and port extraction utilities -- Rule-based packet interception -- In-place packet filtering (no unnecessary allocations) - -### 2. DNSProxy (`olm/dns_proxy.go`) -A DNS proxy implementation using gvisor netstack: -- **Listens on**: `10.30.30.30:53` -- **Upstream DNS**: Google DNS (8.8.8.8, 8.8.4.4) -- **Bypass WireGuard**: DNS responses go directly to host -- **No tunnel overhead**: DNS queries don't consume VPN bandwidth - -Architecture: -- Uses gvisor netstack for full TCP/IP stack simulation -- Separate goroutines for DNS query handling and response writing -- Direct TUN device write for responses (bypasses filter) -- Automatic failover between primary and secondary DNS servers - -### 3. Integration (`olm/olm.go`) -Seamless integration into the tunnel lifecycle: -- Automatically started when tunnel is created -- Properly cleaned up when tunnel stops -- No configuration required (works out of the box) - -## Performance Characteristics - -### Packet Processing Speed -``` -BenchmarkExtractDestIP-16 1000000 2.619 ns/op -``` - -This means: -- Can process ~380 million packets/second per core -- Negligible overhead on WireGuard throughput -- No measurable latency impact - -### Memory Efficiency -- Zero allocations for non-matching packets -- Minimal allocations for DNS packets -- gvisor uses internal buffer pooling - -## How to Use - -### Basic Usage -The DNS proxy starts automatically when the tunnel is created. To use it: - -```bash -# Configure your system to use 10.30.30.30 as DNS server -# Or test with dig/nslookup: -dig @10.30.30.30 google.com -nslookup google.com 10.30.30.30 -``` - -### Adding New Virtual Services - -To add a new service (e.g., HTTP proxy on 10.30.30.31): - -```go -// 1. Create your service -type HTTPProxy struct { - tunDevice tun.Device - // ... other fields -} - -// 2. Implement packet handler -func (h *HTTPProxy) handlePacket(packet []byte) bool { - // Process packet - // Write response to h.tunDevice - return true // Drop from normal path -} - -// 3. Register with filter (in olm.go) -httpProxyIP := netip.MustParseAddr("10.30.30.31") -filteredDev.AddRule(httpProxyIP, httpProxy.handlePacket) -``` - -## Files Created - -1. **`olm/device_filter.go`** -

This file - -## Testing - -Tests included: -- `TestExtractDestIP` - Validates IPv4/IPv6 IP extraction -- `TestGetProtocol` - Validates protocol extraction -- `BenchmarkExtractDestIP` - Performance benchmark - -Run tests: -```bash -go test ./olm -v -run "TestExtractDestIP|TestGetProtocol" -go test ./olm -bench=BenchmarkExtractDestIP -``` - -## Technical Details - -### Packet Flow -``` -Application → TUN → FilteredDevice → [DNS Proxy | WireGuard] - ↓ - DNS Response - ↓ - TUN ← Direct Write -``` - -### Why This Design? - -1. **Wrapping TUN device**: Allows interception before WireGuard encryption -2. **Fast path optimization**: Only extracts what's needed (destination IP) -3. **Direct TUN write**: Responses bypass WireGuard to go straight to host -4. **Separate netstack**: Isolated DNS processing doesn't affect main stack - -### Limitations & Future Work - -Current limitations: -- Only IPv4 DNS (10.30.30.30) -- Hardcoded upstream DNS servers -- No DNS caching -- No DNS filtering/blocking - -Potential enhancements: -- DNS caching layer -- DNS-over-HTTPS (DoH) -- IPv6 support -- Custom DNS rules/filtering -- HTTP/HTTPS proxy on other IPs -- SOCKS5 proxy support -- Metrics and monitoring - -## Extensibility Examples - -### Adding a TCP Service - -```go -type TCPProxy struct { - stack *stack.Stack - tunDevice tun.Device -} - -func (t *TCPProxy) handlePacket(packet []byte) bool { - // Check if it's TCP to our IP:port - proto, _ := GetProtocol(packet) - if proto != 6 { // TCP - return false - } - - port, _ := GetDestPort(packet) - if port != 8080 { - return false - } - - // Inject into our netstack - // ... handle TCP connection - return true -} -``` - -### Adding Multiple DNS Servers - -Modify `dns_proxy.go` to support multiple virtual DNS IPs: - -```go -const ( - DNSProxyIP1 = "10.30.30.30" - DNSProxyIP2 = "10.30.30.31" -) - -// Register multiple rules -filteredDev.AddRule(ip1, dnsProxy1.handlePacket) -filteredDev.AddRule(ip2, dnsProxy2.handlePacket) -``` - -## Build & Deploy - -```bash -# Build -cd /home/owen/fossorial/olm -go build -o olm-binary . - -# Test -go test ./olm -v - -# Benchmark -go test ./olm -bench=. -benchmem -``` - -## Conclusion - -This implementation provides: -- ✅ High-performance packet filtering (2.6 ns/packet) -- ✅ Zero overhead for non-DNS traffic -- ✅ Extensible architecture for future services -- ✅ Clean integration with existing codebase -- ✅ Comprehensive tests and documentation -- ✅ Production-ready code - -The DNS proxy successfully intercepts DNS queries to 10.30.30.30, processes them through a separate gvisor netstack, forwards to upstream DNS servers, and returns responses directly to the host - all while bypassing the WireGuard tunnel. diff --git a/api/api.go b/api/api.go index cf04a89..2316373 100644 --- a/api/api.go +++ b/api/api.go @@ -9,6 +9,7 @@ import ( "time" "github.com/fosrl/newt/logger" + "github.com/fosrl/olm/network" ) // ConnectionRequest defines the structure for an incoming connection request @@ -47,12 +48,12 @@ type PeerStatus struct { // StatusResponse is returned by the status endpoint type StatusResponse struct { -
