feat(dns): implement DNS forwarding and resolution with fragmentation…#234
Merged
Conversation
… support - Added `ResolveUpstream` function to handle DNS queries with optional fragmentation. - Introduced `ForwardOptions` struct to configure DNS forwarding behavior. - Implemented fragmented query sending for both IPv4 and IPv6. - Created unit tests for DNS resolution and timeout scenarios. refactor(utils): replace random number generation with cryptographic methods - Replaced custom random number generation with secure random functions in the `utils` package. - Added `RandUint16` and `RandUint32` functions for generating random values. fix(nfq): remove DNS NAT handling - Deleted DNS NAT management code from `nat.go` as it is no longer needed. - Updated DNS packet processing logic to eliminate reliance on NAT entries. test: enhance unit tests for UDP packet building and checksum validation - Added tests for `BuildUDPPacketV4` and `BuildUDPPacketV6` to ensure correct packet structure and checksum calculations. - Implemented tests for random number generation functions to verify randomness and distribution. chore: update changelog for version 1.64.0
