Bug#158036: libc6: getaddrinfo(3) should do socket(2) test
Package: libc6
Version: 2.2.5-6
Severity: wishlist
It would be nice if getaddrinfo(3) did a (cached) socket(2) test before
looking up names in a particular address family. For instance, it could
avoid doing IPv6 lookups if the kernel does not support IPv6.
This should solve most of those bug reports coming from people complaining
about getaddrinfo(3) ignoring hosts for IPv6 records not explicitly
stated in it. It will also be save a lot of system calls and network
traffic on pure IPv4 machines which currently constitutes the majority
of our user base.
