Sorry for failing to mention that before. That's not an issue. I think it's fixed now in cvs. The reason why I didn't fix this before is that the server I (indirectly) use doesn't return any answer fort he T_AAAA query. The server you're using is sending back a SERVFAIL error. Anyway, I'm treating SERVFAILs now like timeouts when it comes to having received one reply. Jakub will hopefully build a new glibc sometime soon. To comment on a few mails in this thread: - - the problem is new and not new. It is new because of new code paths which are obviously not yet well tested. It is not new in that we had to treat the same situations before. The good news is that the new code should be faster since it waits less in total. - - it is of course necessary to handle all these situations. I know that the server setup quality out there is bad. This is only the tip of the iceberg. Nevertheless, there should be an effort to rectify the situation. For instance, in this specific case, the server I talk to doesn't provide a SERVFAIL answer and therefore the resolver has to reply on a timeout. Multiply this by the number of DNS servers in /etc/resolv.conf and the number of retries and you'll arrive at substantial delays. There is nothing the resolver can do. All one can do is to use nscd to cache the results (albeit it's only effective with the new libc). - - the reason why ping is not affected is that it doesn't look up IPv6 addresses. The problem case is when both IPv4 and IPv6 addresses are needed at the same time using the getaddrinfo interface and AF_UNSPEC as the type. There are likely more problems looming. So keep your eyes open. When problems appear, capture the net traffic to and from port 53 as well as strace of, say, getent. - -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkg4WF4ACgkQ2ijCOnn/RHSpBQCfe1zs1QN70FV2PeTnvJxUHuiT 91kAnjgfqyThJ3FqtMtofoqlP1bENr6h =ypOw -----END PGP SIGNATURE----- -- fedora-test-list mailing list fedora-test-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-test-list
