Pull request overview
This PR updates WSL to integrate a new version of the Microsoft.WSL.DeviceHost package (1.1.14-0), which brings IPv6 support, DNS tunneling, UDP timeout features for virtio proxy networking, and improvements to virtiofs POSIX compatibility. The code changes enable DNS tunneling support for VirtioProxy networking mode, aligning it with the existing Nat and Mirrored modes.
Changes:
- Package update: Microsoft.WSL.DeviceHost from version 1.1.10-0 to 1.1.14-0
- VirtioNetworking refactoring: Replaced boolean parameter with flags enum to support both localhost relay and DNS tunneling features
- Configuration validation: Extended DNS tunneling support validation to include VirtioProxy networking mode
- Test improvements: Re-enabled virtiofs tests that were previously skipped, reflecting improved POSIX compatibility
