It replaces the whole old getaddrinfo-ipv6-sanity.diff patch. It applies to some git glibc I had lying around, it probably also applies to 2.15. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So the patch only prevents IPv6-lookups when people disable IPv6 completely.
