Working on it, assigning to myself for now. Created attachment 957732 [details]
a patch to clear AD flag unless the nameservers are read from /etc/resolve-secure.conf
The attached patch implements one of the ways to handle the difference between trusted and untrusted resolvers. Patched c-ares first attempts to read /etc/resolv-secure.conf for trusted resolver configuration. If that's missing, it reads /etc/resolv.conf as usual but clears the AD flag from any response.
There have been other proposals like a directive to list trusted resolvers in the good old /etc/resolv.conf.
Created attachment 957960 [details]
a simplified version of the patch, also handling the AD flag setting
