- Fixed critical timing issue where tunnel_data arrived before SSH client connection
- Added incoming_buffer to tunnel_t structure for buffering data before SSH client connects
- Modified handle_tunnel_data() to buffer data when SSH client hasn't connected yet
- Updated handle_ssh_server_connection() to send buffered data once SSH client connects
- Fixed socket selection logic to properly handle wssshc buffering scenario
- Resolved 'Bad file descriptor' errors caused by premature data transmission
- Implemented proper data flow: buffer → SSH client connection → send buffered data
- Added comprehensive debug logging for data buffering and transmission
- Fixed race condition between WebSocket data arrival and SSH client connection
- Ensured SSH protocol handshake completes properly with buffered data delivery
- Added proper cleanup for incoming_buffer in tunnel close operations
- Resolved premature socket disconnection by maintaining proper connection state
- Fixed SSH client timeout issues by ensuring timely data delivery
