Package: libc6 Version: 2.6-5 Severity: important Tags: patch
Hi, Tolleff fog Heen has written a patch for the resolver, so that it does not start performing (or waiting for) AAAA lookups unless a globally scoped IPv6 address is present on some interface. Since Debian enables IPv6 by default, most users will have a system with an IPv6 address on the loopback interface (as well as a link-local address on each other interface) which will cause the current code to commence lookups for AAAA records, only falling back to requesting A records when these fail or timeout. The patch here: http://err.no/patches/glibc-only-lookup-ipv6-if-it-makes-sense.diff seems to take a reasonable approach, since it will not be possible to connect to IPv6 addresses without a globally scoped address (plus routing :-) in any case. This is an important issue because some users are so inconvenienced as to be behind broken DNS infrastructure which ignores AAAA requests, resulting in frequent timeouts with much confusion and frustration. Thanks, Andrew McMillan. -- System Information: Debian Release: lenny/sid APT prefers unstable APT policy: (690, 'unstable') Architecture: i386 (i686) Kernel: Linux 2.6.22.1-hippy (SMP w/2 CPU cores) Locale: LANG=en_NZ.UTF-8, LC_CTYPE=POSIX (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/bash Versions of packages libc6 depends on: ii libgcc1 1:4.2-20070712-1 GCC support library libc6 recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
