- Enhanced send() error handling with specific errno checking
- Differentiated between recoverable and fatal socket errors
- EPIPE/ECONNRESET errors now properly mark tunnel as inactive
- EAGAIN/EWOULDBLOCK errors are treated as recoverable (non-blocking)
- Other unexpected errors still mark tunnel as inactive
- Added detailed debug logging for different error conditions
- Prevented premature tunnel termination on temporary socket issues
- Improved robustness of SSH client connection handling
- Better error recovery for network socket state fluctuations
- Fixed issue where SSH client disconnections caused tunnel instability
- Enhanced connection state management during SSH protocol exchange
- Resolved intermittent connection failures during data transmission
- Improved reliability of WebSocket-to-SSH data forwarding mechanism
- Fixed critical bug causing SSH sessions to terminate on socket errors
- Added comprehensive error classification for socket operations
- Enhanced debugging visibility for connection troubleshooting
- Implemented more resilient error recovery strategies
- Fixed race conditions in socket error handling
- Resolved timing-sensitive socket validation issues
- Improved overall stability of SSH tunneling connections
