From RT#6922. When we're converting a host/service pair into a principal
|
||
|
|
name, specify AF_UNSPEC instead of AF_INET4 and then maybe AF_INET6 to try
|
||
|
|
to avoid libc having doing a PTR lookup because we also specify
|
||
|
|
AI_CANONNAME. Add AI_ADDRCONFIG because it's usually the right idea.
