From 7373b0b6f7dda50e328ef7a2ea27006a53a47570 Mon Sep 17 00:00:00 2001 From: Max Date: Thu, 12 Mar 2026 20:35:17 +0800 Subject: [PATCH] feat(tai): enhance gRPC tunnel functionality and internal host handling - Introduced ExpandHosts function to parse and expand comma-separated host entries, including special values like "internal" and "localhost". - Updated gRPC server to utilize the new ExpandHosts function for improved host management. - Added HostHasInternal function to check for "internal" in host strings, enhancing configuration flexibility. - Implemented new gRPC endpoints for TaiTunnel registration and forwarding, improving tunnel communication capabilities. - Refactored authentication logic to include new TaiTunnel endpoints, ensuring proper access control.
