- Add Validate method to ServerConfig to validate port ranges, domain format, TCP port ranges, and other configuration items
- Add configuration validation logic in server.go to ensure valid configuration before server startup
- Improve channel naming in TCP connections for better code readability
- Enhance data copying mechanism with context cancellation support to avoid resource leaks
- Add private network definitions for secure validation of trusted proxy headers
fix(proxy): Strengthen client IP extraction security and fix error handling
- Trust X-Forwarded-For and X-Real-IP headers only when requests originate from private/loopback networks
- Define RFC 1918 and other private network ranges for proxy header validation
- Add JSON serialization error handling in TCP connections to prevent data loss
- Fix context handling logic in pipe callbacks
- Optimize error handling mechanism for data connection responses
refactor(config): Improve client configuration validation and error handling
- Add Validate method to ClientConfig to verify server address format and port validity
- Change configuration validation from simple checks to full validation function calls
- Provide more detailed error messages to help users correctly configure server address formats
- Set a read timeout before the TLS handshake to prevent slow handshake attacks
- Clear the read timeout setting after a successful handshake
- Enable session resumption for server and client TLS configurations
- Explicitly prioritize the use of server-side cipher suites (ignored in TLS 1.3 but retained to ensure consistency)
- Optimized terminal output style and configuration management using libraries such as `lipgloss` and `go-json`
- Introduced the `ui` package to unify the display logic of colors, tables, and prompts
- Updated the README document structure and installation script links to improve readability and internationalization support
- Improved the interaction flow and log display effects of the daemon startup and attach commands
- Fixed some command parameter parsing issues, improving program robustness and user onboarding experience
