Control-D-Inc/ctrld v1.4.4

Release v1.4.4

on GitHub

Minor Release

This contains new features, improvements, and bug fixes..

Added.

• ctrld will now preserve search domains settings.

Improved

• To enhance security on Windows and macOS desktop environments, ctrld no longer listens on the broad 0.0.0.0 address by default, thus preventing potential DNS amplification and abuse.
• The OS resolver now incorporates a Singleflight pattern, effectively de-duplicating repeated queries to the upstream and significantly reducing network operations. Furthermore, a hot cache is implemented to provide short-term storage of query responses.
• Make IPv6 detection more reliable by not relying exclusively on DNS port availability.
• Make TLS certificate verification error messages more helpful when the certificate's issuing authority is unknown.

Fixed

• Corrected an issue with incorrect Edns0 client cookie setting for cached DNS answers.
• Corrected an issue causing ctrld reload command emits an invalid error message.
