https://bugzilla.novell.com/show_bug.cgi?id=684534 https://bugzilla.novell.com/show_bug.cgi?id=684534#c0 Summary: getaddrinfo-ipv6-sanity.diff no longer works Classification: openSUSE Product: openSUSE 11.4 Version: Final Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: pbaudis@novell.com ReportedBy: mls@novell.com QAContact: qa@suse.de Found By: Customer Blocker: --- The getaddrinfo-ipv6-sanity.diff makes glibc not do IPv6 AAAA requests if ipv6 is disabled (i.e. there's no ipv6 interface config). The current glibc code calls gethostbyname4() if AF_UNSPEC is used, it ignores the usable_ipv6 parameter introduced with the getaddrinfo-ipv6-sanity.diff. I propose to only use gethostbyname4() if usable_ipv6 is true, i.e. change if (fct4 != NULL) to if (fct4 != NULL && usable_ipv6) in sysdeps/posix/getaddrinfo.c Side note: The debian version of getaddrinfo-ipv6-sanity.diff contains a slightly different getaddrinfo-ipv6-sanity.diff, it skips interfaces where there is only a link=local ipv6 address defined when doing the ipv6 usability check. That's good for people with routers running a broken DNS server, but it forbids link-local IPv6 networks. So I'm not sure if it's a good idea or not. -- 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.

It would have been better is there was another way to communicate the non-ipv6 setting to that function, alas, there isn't (we could introduce a new flag for _res.options and check that in the various gethostbyname4_r implementation). It would be better because gethostbyname4_r also provides more information at once than gethostbyname3_r. It would also be better because then only the DNS nss routine could disable ipv6 queries. The other nss routines (like host_files) could still return ipv6 addresses, which is one of the problems that existed once with AI_ADDRCONFIG specified, when the notion of "system has ipv6 interface" was implemented incorrectly. In any case, yes, I think a change like proposed in initial comment seems sensible (on top of the other work around we have anyway already). -- 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.

Well, we can't have it both ways. Either we do return ipv6 addresses when there's no interface with ipv6, or we don't. bug 706719 is about a system where there's no ipv6 interface, but still expects a ipv6 address to be returned. It doesn't expect an IPv6 to be returned. It only expects not to get the same IPv4 address returned twice. And at least according to the "ip" output there is an IPv6 address configured for lo (though I might just have missunderstood you):

1: lo: mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 brd 127.255.255.255 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 52:54:00:ba:a7:83 brd ff:ff:ff:ff:ff:ff

...

I would be inclined to say that this expectation is wrong, and indeed the past years changes in the resolver always worked towards not returning ipv6 addresses for machines were it's reasonable sure that it doesn't have ipv6. That would be ok, but why is it returning 127.0.0.1 twice, now?

See also bug 606980 . Basically upstream decided that returning this twice for localhost is okay. You'll somehow have to deal with this.

Yeah. See further down that bug report. It enumerates all issues connected with this problem. If we remove localhost from ::1 in /etc/hosts ipv6-only systems wouldn't work correctly anymore. If we leave it in we get double returns of 127.0.0.1 because of the rewriting on ipv4-only systems. Catch 22. I don't have a good solution for this, but I think the lesser evil is to deal with the doubled returns. -- 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.

That would rely on us always having localhost in /etc/hosts for 127.0.0.1 (and not only ::1), which seems a sensible requirement. But I don't know the implications of that.
