世界	07d9ec4f68	Improve `local` DNS server on darwin We mistakenly believed that `libresolv`'s `search` function worked correctly in NetworkExtension, but it seems only `getaddrinfo` does. This commit changes the behavior of the `local` DNS server in NetworkExtension to prefer DHCP, falling back to `getaddrinfo` if DHCP servers are unavailable. It's worth noting that `prefer_go` does not disable DHCP since it respects Dial Fields, but `getaddrinfo` does the opposite. The new behavior only applies to NetworkExtension, not to all scenarios (primarily command-line binaries) as it did previously. In addition, this commit also improves the DHCP DNS server to use the same robust query logic as `local`.	2025-12-25 14:48:52 +08:00

This caused cache misses when ipv4_only was configured globally but the cache lookup expected both A and AAAA records. Remove LookupCache and ExchangeCache from Router, as the cache checks inside client.Lookup and client.Exchange already handle caching correctly after rule matching with the proper strategy and transport.	2025-12-21 16:59:10 +08:00
