FYI, today Mozilla released Firefox 4.0 beta 11, which now calls getaddrinfo() with the AI_ADDRCONFIG flag. You get it from http://www.firefox.com/beta/. This solves half of the problem. The remaining piece is now to make glibc ignore link-local IPv6 addresses when called with the AI_ADDRCONFIG flag. (This is how all other major operating systems behave already.) I have a bug open in the glibc bugzilla at http://sourceware.org/bugzilla/show_bug.cgi?id=12377 - it would be really great if the Ubuntu glibc developers could help out by writing a suitable patch and attach it to the bug report. I don't think it should be very hard (just extend the already existing logic that ignores loopback addresses). Unfortunately, I'm not much of a programmer myself...

Here's one half of the solution - it's a patch to glibc that makes getaddrinfo() ignore link-local addresses when called with the AI_ADDRCONFIG flag set.

[Bug 417757] Re: [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
There is no question that the underlying problem here is defective DNS resolvers that choke on perfectly legitimate AAA queries. That said, there are a couple of issues present in software shipped by Ubuntu that cause the problem to manifest itself as slowdowns noticeable by end users: 1) When called with the AI_ADDRCONFIG flag, libc's getaddrinfo() function does not disregard link-local IPv6 addresses when determining whether or not the local host has usable IPv6 connectivity. Since every IPv6-capable OS will have link-local IPv6 addresses assigned to all interfaces - regardless of any external connectivity being available or not - this essentially makes AI_ADDRCONFIG on Linux useless for the purpose of suppressing queries when they're not useful. I've submitted a bug to the GNU libc upstream about this issue at http://sourceware.org/bugzilla/show_bug.cgi?id=12377. getaddrinfo() on other operating systems (such as Apple Mac OS X and Microsoft Windows) does disregard link-local IPv6 addresses when called with AI_ADDRCONFIG, which is why the problem appears to affect GNU/Linux distributions more than other operating systems. 2) Many applications do not set the AI_ADDRCONFIG flag when calling getaddrinfo(). This includes, notably, Mozilla Firefox. However, a patch to correct this has recently been committed to the mozilla-central developement repo and will likely be part of Firefox 4.0 beta 11 (hopefully also 3.6.15), see https://bugzilla.mozilla.org/show_bug.cgi?id=614526. Microsoft Windows enables the use of AI_ADDRCONFIG as the system-wide default, as far as I know, which explains why it is able to cope better with those broken middleware boxes. Mac OS X does not set AI_ADDRCONFIG by default, however it has an extremely short timeout waiting for responses after the A response has been answered (around 125ms), which in turn hides the problem from most end users. Additionally, most major browsers (except Firefox) do set AI_ADDRCONFIG explicitly, which suppress the problematic queries in the first place. So what Ubuntu could to avoid this problem is 1) to develop and include a patch to glibc that makes getaddrinfo() ignore link-local addresses for AI_ADDRCONFIG purposes, and 2) to back-port the NSPR patch already committed to mozilla-central to the version of Firefox shipped (or wait until Mozilla releases a new version with the patch already included).

[Bug 417757] Re: [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
Thanks Derek. Your patch worked for me. I had already disabled IPv6 via sysctl and took all IPv6 addresses off my interfaces. The about:config solves firefox, but mutt and ssh were still a problem. I'm a bit surprised at some of the suggested workarounds. I wouldn't really blame the resolvers - things shouldn't be doing lookups if ipv6 is disabled in the first place. It might be possible to blame the authors of virtually every network-aware app, but that isn't realistic. Most of us running ubuntu in corporate networks with broken Microsoft resolvers are doing so completely unsupported. If you open a ticket, you'll be lucky if ignoring it is the worst that happens. More likely you'll be told to use a supported environment and just give them another reason why linux users are an expensive problem. Go fix your resolvers is just not a reasonable response. Using other DNS servers doesn't work in this case either, because they don't have access the intranet zones. -- [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It took forever for this to get fixed for Karmic, and now, after upgrading to Lucid, the bug is back. This is absolutely ridiculous.

Jeremy. Member of the IPv6 taskforce eh. Well, it is fortunate for me that the code snippet I posted in #288 and #290 worked, because otherwise Ubuntu's pushing forward would have pushed it right off our (large) corporate network. We have 0 control over that infrastructure. So it was either eliminate the slow and steady introduction of Linux and more open services in general, or find a workaround for this *bug*. There's ideology, and then there's pragmatism. It may not work for everyone, but it'd be nice if something equiv to defaulting to AI_ADDRCONFIG without the need for that preload trick was made available in some alternate package that people could add, see if it works for them, and remove once transitions were complete. -- [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 417757] Re: [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
Dear Derek, there is a way to fix this problem in your large corporate network, like we did for that small corporate network that I am using: fix the resolvers. As you are claiming to have a large corporate network, you most likely have only a handful of recursors but you might have a 100k clients, lets see which ones are easier to upgrade, 100k clients which are all over the place or that 10 max or so recursors easy pick I would say. The thing you most likely are forgetting is the fact that the DNS recursors that you are using are not only broken for records, but most likely for every single other address. Thus, by resolving this issue you will solve other magical problems too. You can directly move on to support DNSSEC too for that matter if you are busy anyway. Yes, the problem is annoying, no there is not much that Ubuntu or any other OS can do about this. Thus fix the problem in the right spot. -- [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This is where pragmatism comes in. We have absolutely no control over those resolvers, and even if we had any influence whatsoever with those who did, corporate networks are very slow to change. Ubuntu is the outsider. The Windows machines work. Your solution is not a pragmatic one. So, while being pure is good, I thought Ubuntu stayed out of such things. That's why Ubuntu offers easy integration of binary drivers for ATI and nVidia, why Ubuntu has a restricted-extras for convenient meta. Simply because IPv6 is *better* doesn't mean you should sacrifice adoption for the ideal. Using AI_ADDRCONFIG is simple enough, and as noted browsers like Firefox and Chrome have adopted that. What would be nice would be a simple package that forces it across the board, simply as an option for broken networks. -- [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 417757] Re: [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
I have to agree with Derek. With due respect to all the techs who do the hard work of keeping Ubuntu (and especially Kubuntu in my case) so great, I find that, as technical folks, we sometimes get overly focused on the technical side and forget about the larger world in which that exists. Sometimes the technically correct solution is not the right solution in the real world, at least not at first. Because of all the issues with Karmic, this should have been anticipated and accounted for in Lucid. By this I mean that clear documentation, fixes and workarounds should have been provided - if the problem could not be accounted for silently in code. This problem is a huge hassle for users who aren't up to speed on the technical side of connecting to the internet. Those who are may look down on those who are not, but that's no way to run an operating system. Derek wrote: This is where pragmatism comes in.

[Bug 417757] Re: [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups
hello, flurin derek: thanks for the information. I'll definitely try the pdns-recursor workaround. the firefox workaround didn't work for me, unfortunately. but i'll try changing the dns and forcing AI_ADDRCONFIG. Lets see what happens. As for windows 7, I took out my installation CDs for Windows Vista that came with my Lenovo T400. Installation, with all the crap customizations, took about 2 hours? (I just phased out and started playing GTA4 after a certain point). After that the goddamn updates took literally 12 hours (with all the restarts and my 2 MB shared connection). I ended up with a system that booted up in a minute, with a fingerprint reader that didnt work and reintroduced me to the general slowness that drove me to linux in the first place. So now I'm sitting here with lucid back on and checking proposed updates. I have horrible internet, but atleast I don't want to throw my laptop out the window. By the way, I had a Live CD of openSuse 11.2 lying around (KDE) and I can confirm that I had no issues whatsoever with my internet when I installed that on my system as was the case with Jaunty. Fedora 13 and the latest PCLinuxOS, however, suffer from the same issue. Additionally, the problem is curiously confined only to my internet connection at home and not at work. I initially had the same router (Linksys WRT54G) at home and at work. I changed the one at home thinking that it may have been a router problem and got a DLink Wireless N router instead. That did not work. I have the same ISP at home and work but different modems: a ZyXEL P-600 at work and an Alcatel SpeedTouch Home at home. The modem at home is considerably older then the one at work. Additionally, I have also found that if the internet on my Lucid box is acting up at home, it slows down the internet for everyone else connected to the router. So the lucid lynx is not only managing to annoy me but also other windows users (my wife) as well! I hope that these workarounds work - Lucid is actually the best OS I've used in a very long time. -- [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Are there any updates with regards to this bug? I've been waiting patiently for some kind of fix (I check proposed updates everyday in the hope that there is some mention of this). My system is becoming frankly unusable since 90% of what I do is on the net. I've seen other bugs that have been open for five years or so and I fear that this one is going the same route. No updates whatsoever, even the discussion on this list have stopped. It's a pity that I'm thinking of installing something else (even a windows 7 installation at this point) even though I've been thoroughly satisfied with 10.04 in all other respects. -- [regression] all network apps / browsers suffer from multi-second delays by default due to IPv6 DNS lookups https://bugs.launchpad.net/bugs/417757 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

omair, if you can't change your DNS, I've found that forcing AI_ADDRCONFIG as noted in #288, #289 and (importantly) #290 works nicely for me. Also, if it causes trouble for you, you can just remove or comment out the ld.so.preload line. I've applied it on 5 computers here at work w/ no issues and immediate improvements, where DNS changes are simply not an option. I do also set: network.dns.disableIPv6;true in Firefox as well.

// getaddrinfo wrapper

#define getaddrinfo _foo
#include netdb.h
#undef getaddrinfo
int getaddrinfo(const char *node, const char *service, struct addrinfo *hints,
struct addrinfo **res)
{
typedef int (*FP_getaddrinfo)(const char*, const char*, struct addrinfo*,
struct addrinfo **);
FP_getaddrinfo org_getaddrinfo = dlsym(((void *) -1), getaddrinfo);
hints-ai_flags|=AI_ADDRCONFIG;
return org_getaddrinfo(node, service, hints, res);
}
Running:
gcc -fPIC -c -Wall getaddrinfo_wrap.c getaddrinfo_wrap.o
gcc -shared getaddrinfo_wrap.o -ldl -lstdc++ -o getaddrinfo_wrap.so
sudo cp getaddrinfo_wrap.so /usr/local/lib/
sudo chown root:root /usr/local/lib/getaddrinfo_wrap.so
sudo sh -c echo /usr/local/lib/getaddrinfo_wrap.so /etc/ld.so.preload
There. No more problems.
BTW, I do have ipv6 interfaces after stripping all my ipv4 hacks from above,
that seems utterly irrelevant to this finally working.
I of course have no idea what the results of this could be on various apps, but
at least the ones I use seem happy.
