ospab 7e3b2e6633 fix(client): prevent TUN read loop from crashing on invalid IP packets (fixes LTE MTU/CLAT issues) 2026-05-30 01:42:18 +03:00

ospab af4a16e809 fix(android): protect xhttp TCP socket from VPN routing loop 
When using xhttp (UoT) mode on Android, the underlying TcpStream was
not protected with VpnService.protect(fd). This caused the TCP connection
to be routed back into the TUN interface, creating an infinite routing
loop and failing the connection immediately.

Added Android-specific socket protection to the TcpStream in connect_xhttp.
This fixes xhttp/UoT mode on mobile networks.

ospab ec333470aa fix(reality): fix TLS 1.3 handshake causing 1KB DPI cutoff on mobile 
The core bug: server sent 5 TLS records in server_hello but client only
read the first one (ServerHello), then passed remaining bytes (CCS + fake
records) into RealityStream. RealityStream saw 0x14 (CCS) != 0x17 and
immediately returned an error, killing the connection.

Changes:
- reality.rs: append ChangeCipherSpec after ClientHello (RFC 8446 D.4)
  export REALITY_SERVER_HANDSHAKE_RECORDS=5 constant
- xhttp.rs: drain all 5 server handshake records before creating RealityStream
- uot.rs: rebuild server_hello as proper 5-record TLS 1.3 flight:
  ServerHello + CCS + fake EE (108B) + fake Cert (812B) + fake Fin (52B)
  drain client CCS from raw stream before wrapping in RealityStream

ospab 2c46750687 fix: remove DNS interception on server, fix TUN routing on Windows and Linux 
- 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
