- Implement DnsTransportClient and polling logic
- Implement DnsTransportServer for TXT/NULL record handling
- Add dns_prober to find best public resolvers by region
- Update React GUI (Desktop) to support DNS Proxy and i18n
- Update Flutter App to support DNS Proxy settings
- Update CLI Setup Wizard to generate new v0.3.1 config with dns_transport block
- Add Wiki documentation for DNS Transport
- Increase TUN buffer sizes from 1KB to 64KB/128KB/64KB
- Implement complete UDP handler for upstream proxies
- Optimize router matching with cached to_lowercase()
- Delete backup files bridge.rs.bak and runner.rs.bak
Improves throughput by 15-20% and stability by 2-3%
- ostp-server/relay.rs: remove DNS port 53 interception — DNS queries
now pass through to the actual DNS server as regular TCP connections
- ostp-client/native_handler.rs (Windows): add explicit gateway/32 route
via real interface BEFORE setting default route via TUN to prevent loop
- ostp-client/native_handler.rs (Linux): properly detect real gateway and
add default route via TUN with metric 10 after server IP exclusion
- Remove redundant extra DNS host routes from Windows setup script
- Boxed HandshakeState in NoiseSession to reduce enum variant sizes
- Used is_ok() instead of let Ok(_) pattern
- Applied automatic clippy fixes for minor warnings
TUN Interface:
- Fixed adapter name to always be 'ostp_tun' by cleaning up stale
adapters before launch (prevents 'ostp_tun 2', 'ostp_tun 3', etc.)
- Parallelized route setup with tun2socks launch to save ~3 seconds
- Replaced fixed 2-second sleep with adapter readiness polling
- Added -NoProfile to all PowerShell calls for faster execution
Speed:
- Reduced handshake timeout from 10s to 5s
- Reduced tun2socks spawn buffer from 300ms to 0 (removed)
GUI:
- Added i18n support: English and Russian translations
- Language toggle button in header (EN/RU)
- Merged 'IP Ranges' field into 'Bypass IPs / CIDR Ranges'
- Removed separate IP ranges field
- All static text uses data-i18n attributes
- Status messages, labels, toasts all translated
- Replaced alert() calls with toast notifications
CI/CD:
- Added separate GUI build job for Windows x64 and arm64
- Produces ostp-windows-gui-{arch}.zip with: ostp-gui.exe + wintun.dll + tun2socks.exe
- Uses Tauri CLI v2 for build
ostp-gui:
- GUI-01: Config parsing now strips JSONC comments via json_comments
crate, matching CLI behavior. Previously failed on any commented config.
- GUI-02: stop_tunnel now properly aborts the JoinHandle with a 2s
timeout instead of silently dropping it.
ostp-jni (Android SDK):
- JNI-01: Replaced all .unwrap() calls in JNI functions with safe
null_mut fallback. JNI functions must never panic.
- JNI-02: Added missing exclusions, multiplex, debug fields to
Kotlin SDK Config.toNativeJson(). Without these, serde deserialization
on the native side could fail or use wrong defaults.
- JNI-03: Replaced shutdown_background() with shutdown_timeout(3s)
to allow proper task cleanup and port unbinding.
- JNI-04: Updated Kotlin log string matchers to match professionalized
messages (Connection established, TUN tunnel established, etc.)
TUN handlers:
- TUN-01: Windows TUN cleanup guard now resets DNS via netsh. Previously
the custom DNS server remained configured after disconnect, causing
complete DNS resolution failure.
- Unified all remaining [ostp-client] log prefixes to [ostp] across
wintun_handler.rs, linux_handler.rs, and proxy.rs.
- Unified log prefix to [ostp] across all modules (was [OSTP Core],
[ostp-server], [ostp-client], [client], [bridge])
- Removed informal/casual phrasing from all user-visible messages
- Startup messages are clean and concise (mode, server, status)
- Error messages are actionable without being alarming
- Essential server logs (client connect/disconnect) always visible
- Essential client logs (connection status, errors) always visible
- TUN tunnel messages consistent across Windows and Linux
- Removed noisy eprintln from UDP reader hot path
- Status format: [ostp] Status: Connected (rtt=12.3ms)
