Drip 0.6.2 డౌన్‌లోడ్

Overview
This release introduces IP-based access control functionality for HTTP, HTTPS, and TCP tunnels, allowing users to restrict access based on client IP addresses using whitelist and blacklist rules.
New Features
IP Access Control
- Whitelist/Blacklist Support: Configure allowed and denied IP addresses for tunnel access
- CIDR Range Support: Both --allow-ip and --deny-ip flags support CIDR notation (e.g., 192.168.0.0/16, 10.0.0.0/8)
- Single IP Support: Individual IP addresses are also supported (automatically converted to /32 for IPv4, /128 for IPv6)
- Multi-tunnel Support: IP access control works across HTTP, HTTPS, and TCP tunnels
Usage Examples:
# Allow only specific IP ranges
drip http --allow-ip 192.168.1.0/24,10.0.0.0/8

# Deny specific IPs or ranges
drip tcp --deny-ip 1.2.3.4,192.168.0.0/16

# Combine allow and deny rules
drip https --allow-ip 10.0.0.0/8 --deny-ip 10.0.1.0/24
Access Control Rules:
1. If IP is in deny list → reject
2. If whitelist is configured and IP is not in whitelist → reject
3. Otherwise → allow
Improvements
Server Configuration Validation
- Added Validate method to ServerConfig for validating port ranges, domain format, and TCP port ranges
- Configuration is now validated before server startup to catch errors early
- More detailed error messages help users correctly configure server addresses
Security Enhancements
- Trusted Proxy Headers: X-Forwarded-For and X-Real-IP headers are now only trusted when requests originate from private/loopback networks
- Private Network Definitions: Added RFC 1918 and other private network range definitions for proxy header validation
Connection Handling Optimizations
- Improved channel naming in TCP connections for better code readability
- Enhanced data copying mechanism with context cancellation support to prevent resource leaks
- Added JSON serialization error handling in TCP connections to prevent data loss
Bug Fixes
- Fixed CIDR parsing in deny list - previously CIDR ranges like 192.168.0.0/16 were silently ignored
- Fixed context handling logic in pipe callbacks
- Optimized error handling mechanism for data connection responses
