It has always been our intention to provide a kernel update immediately post-release to correct this issue.

If you turn timestamps off, at rates of 1GB/s and above you are exposed to possible sequence number wraparound. This in turn can lead to data corruption. Without timestamps there is no PAWS protection (Protection Against Wrapped Sequence numbers) and thus at high enough data rates new data can be interpreted as old data and vice versa, corrupting your data stream. Ubuntu made the wrong decision, there is simply no argument for the way this was "handled." I don't understand why everyone gets their tits in a knot when even the slightest suggestion of slipping a release is suggested in order to fix a serious bug like one of this magnitude. It is always the right thing to do, and it avoids crap like what is happening here. To reiterate, if timestamps are off, you are exposed to possible data corruption. -- unable to visit some websites and ftpsites with 2.6.27 https://bugs.launchpad.net/bugs/264019 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

Good point regarding the opacity of the release note entry's title, thanks. I've updated this now to read: Unable to browse some websites when connected to particular Internet providers I'm reluctant to name particular ISPs or routers in our release notes because we haven't established what routers have the bug. Given that users have reported it with Verizon with multiple models of DSL routers it seems likely that the problem lies with Verizon's routers and not with the Westells themselves, but interjecting guesses into the release notes isn't what we want to be doing. And yes, this is a question of being able to release on time /at all/, not just a question of QAing the result.

If the problem here is one of QA process having rebuilt and not rebuild time itself, what is needed here IMO is a clear case of risk management.

[Bug 264019] Re: unable to visit some websites and ftpsites with 2.6.27
Just to clarify on my point above, what Nick said about it being people who aren't technically minded being affected by this is what I was attempting to show. On mass, the people who are affected by this will be users who don't read the release notes (I often don't bother, for example, only when downloading RC builds do I generally do that). That means that saying "oh well all they have to do is sudo blah and it will all work" is absolutely pointless. This gives the worst out of the box experience for any linux converts and I am anticipating my girlfriend ringing me at the end of the month because she's upgraded her laptop and the internet no longer works... If you truly care about ubuntu being "linux for human beings" then you will delay the release to get this fixed - having network access is one of the most fundamental features of the distro. How many threads in the forums are you anticipating seeing of people who can't be bothered to search the forums, don't read the release notes and seem to have internet access issues? (assuming they can get to the forums!) Let's look at the release notes. First, the description isn't /technically/ accurate: the issue isn't a result of tcp timestamping, it's a result of the ordering and disabling timestamps happens to fix the issue. So, I'm a home user and I'm told I should run the command: sudo sysctl -w net.ipv4.tcp_timestamps=0 Great, where do I type that? What's this TCP stuff anyway?

Thanks all for the TCP timestamps workaround on the 8.10 rc release notes page. I can confirm experiencing the described "certain sites" connection problem in ibex after an upgrade from hardy LTS. I am using a Westel Model 327W wired/wireless router on Verizon DSL.

Can someone change the release notes header to read "Severe Connectivity Problems caused by Enabled TCP Timestamps behind older routers". the heading "TCP Timestamps" says nothing that will catch the eye of someone reading the release notes before an upgrade. Please also put "Verizon" in bold. This is a really big, problem. A dangerous one for linux in terms of impressions. When 20% of ubuntu users on the east coast of the U.S. are going to drop off the net on upgrade, you want to warn them first. We also need to pressure Verizon (Westtel) and Netgear to get their shit together.

The kernel fix is known upstream; implementing it requires kernel uploads and installer rebuilds, which it's just not possible to fit in between the release candidate and the release. We will certainly want to include this fix in a kernel update as soon as possible after the release, but this is unfortunately in a class of bugs that we can't fix the week of release (even turning timestamps off requires a kernel upload, unless we want to permanently disable tcp timestamp support for Ubuntu 8.10). FWIW, we don't consider any of the issues docuented in the release notes to be "minor"; the release notes are the authoritative place to find information about the /major/ issues affecting a release.

[Bug 264019] Re: unable to visit some websites and ftpsites with 2.6.27
I've added this text to the release notes (wiki notation):
== TCP timestamps ==
Linux 2.6.27 now sets the timestamps option in TCP packets
([[http://www.ietf.org/rfc/rfc1323.txt|RFC 1323]]), an option dating
from 1992 to improve performance over high-bandwidth-times-latency paths
and to improve reliability over high-bandwidth paths, which was
previously omitted by mistake.
However, this change appears to cause problems for some users, believed to be
due to buggy routers between the user and the destination server (for example,
this has been reported by several Verizon DSL users). If your Internet
connection mostly appears to be working correctly, but you have problems
connecting to certain sites, then try the following command: {{{
sudo sysctl -w net.ipv4.tcp_timestamps=0
}}}
This change will normally expire the next time you restart your computer. If it
fixes the problem, then you can make the change permanent by running `sudo
editor /etc/sysctl.conf` and adding the following line to the end of that file:
{{{
net.ipv4.tcp_timestamps = 0
}}}
The real bug here is in your router (if you own one) or your ISP's
routers. If a firmware upgrade is available for your router, follow your
manufacturer's instructions to upgrade it. Otherwise, contact the
support department of your router manufacturer or your ISP for further
advice.
See [[https://launchpad.net/bugs/264019|bug #264019]], and thanks to

Thanks for the feedback; marking this as invalid for the linux package, because this has been isolated as a router bug and not a bug in the Linux kernel. It is not generally appropriate to diverge from the upstream kernel over policy decisions in the IP stack, when the kernel is not actually buggy and the problem is with other routers that fail to correctly handle compliant TCP/IP traffic.

It does not matter which router you use. I have tried this on a few Verizon DSL connections with different DSL modems and routers (Netgear, Linux gateway, Linksys), they all have the same problem. I am able to ping the server and since one of my servers on the inet has this problem I was able to do a tcpdump on my laptop and server. The server definitely gets the request and even sends a response. I did not spend much time verifying each of the lines in the tcpdump but there definitely is a request and response. I have a server that is on a DSL connection that is on Cloud9 but their lines are leased from Verizon so it is basically a Verizon connection. When my laptop is on a cable connection I can get to all sites just fine, but I am not able to get to the site on that server.

[Bug 264019] Re: unable to visit some websites and ftpsites with 2.6.27
The complicating factor is that the problem does not exist at all on 2.6.24 (running intrepid userland), but is very easy to reproduce with 2.6.27. I agree that our network environments are related, but the kernel version seems to be a factor, as well. I have a Westell WireSpeed Data Gateway. I can get the exact model if it's important. -- unable to visit some websites and ftpsites with 2.6.27 https://bugs.launchpad.net/bugs/264019 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 264019] Re: unable to visit some websites and ftpsites with 2.6.27
I've run a comparable test against www.youtube.com here, and find that the server responds to the query with one very large, fragmented packet. Given that these packet fragments never appear at all in Forest's trace, and given that there's a common theme that this affects users of Verizon DSL, it seems likely that the router is discarding them for some reason. Nothing stands out to me in the packet trace that would explain why those fragments would be discarded, though.

[Bug 264019] Re: unable to visit some websites and ftpsites with 2.6.27
Such a bug has a significant impact on the release so I'm confirming this for intrepid, but from the available information, I'm not sure that we're really looking at a kernel bug here. The wireshark traces available certainly seem to indicate a failure of the return traffic from the server to be received by the client, which I would expect to manifest much more dramatically if it were the result of a bug in the client stack. I've requested full pcap traces, which may provide more information here. ** Changed in: linux (Ubuntu Intrepid) Importance: Undecided => High Status: New => Confirmed -- unable to visit some websites and ftpsites with 2.6.27 https://bugs.launchpad.net/bugs/264019 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

I have this problem as well. Running 64 bit, wireless with ndiswrapper, verizon dsl. I would like to mention that the websites that don't work differ from person to person. I couldn't access launchpad for instance. Switching to the older kernel fixed my problem, I didn't get to try firestarter because google hadn't cached this page since people mentioned that :-). People on the ubuntu forums suggested using some network-manager ppa, but because I couldn't access launchpad, I coudn't do that.

BTW, firestarter doesn't seem to help here. I suspect that if it appears to work for anyone, it's probably coincidental. Please feel free to correct me if I'm wrong. What's confusing about this bug is that it certainly appears to be in the TCP stack somewhere, but it obviously isn't affecting a lot of people or there would be more reports. It's not limited to a particular driver, though, because I see it with both my wired and wireless connections. This is a real show-stopper for me, though.

** Description changed: 2.6.27 introduced a networking issue, leaving sites like youtube.com, and microsoft.com not working via the web browsers on one of my systems (but not others). This system, like the others, was upgraded from Hardy. I am unable to transfer files from archive.ubuntu.com via apt (http) or lftp (ftp, not http). I can connect via ftp and traverse and list files/directories, but when I try to "get", the transfer stays at 0 bytes. Likewise, if I do a naive "telnet youtube.com 80" GET / HTTP/1.1 HOST: youtube.com I get a response, but when the web browser (firefox,opera) attempts to load these sites they do not progress - the 'transferring' status stays fixed. Some web sites (google, yahoo) work fine though. When I reboot this system back to the 2.6.26-5 kernel everything works as it should. I tried setting rp_filter=0 on all, eth0, and default (instead of the Ubuntu default 1), as I have seen this and ecn settings cause site specific problems. Those settings had no effect in this case. I only have remote access to this system. I am able to remotely ssh into this box, but I could not scp a file to it. I was able to scp to - this host from host on the same local network, however.
