[Bug 229848] New: unable to access certain web sites
https://bugzilla.novell.com/show_bug.cgi?id=229848 Summary: unable to access certain web sites Product: openSUSE 10.2 Version: Final Platform: Other URL: http://www.marymount.edu/ OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: mrmazda@ij.net QAContact: qa@suse.de There's a long thread discussion about this on the opensuse mailing list. http://www.marymount.edu/ and http://www.keh.com/ are the only two sites so far known to exhibit this problem. The thread was started by Chip Cooper at http://lists.opensuse.org/opensuse/2006-12/msg02707.html because the subject URL is his work web site. To reproduce: 1-open any web browser in 10.2 2-try to open subject URL or the alternate URL Actual behavior: 1-perpetually "waiting for www.marymount.edu" (e.g. from Firefox) Expected behavior: 1-site opens fully in short order Notes: 1-firewalls, proxies and hardware are not factors 2-most who try fail to reach site (very few reports of success) 3-failure also using Debian Etch 2.6.18-3 and Fedora 6 2.6.18-1 on exact same system as 10.2 4-failure does not occur in 10.0 2.6.13-15.12 or Ubuntu 6.10 2.6.15-27 on exact same system as 10.2 5-failure in SUSE occurs with 2.6.18.2-33 and 2.6.18.2-34 kernels, default and bigmem 6-booting 10.2 with 2.6.16 kernel solves problem for the OP 7-booting 10.2 with generic 2.6.19 solves problem for me 8-failure also occurs attempting to fetch URL with wget 9-ping and traceroute also fail to reach the URL 10-as yet no reports of useful information from anyone who's tried wireshark -- 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, or are watching someone who is.

Well someone may have problems with fragmenting packets, but its not THESE sites. Its clearly the SUSE kernel. 10.1 had Window scaling turned on, and had no trouble loading marymount.edu. 12.2 with the same setting fails. So setting scaling off merely masks the problem.

These sites must have problems with TCP fragmentation, and I suspect the reason why it isn't an issue with other versions is that the default window is too small. A LAN trace shows that the remote site never responds, probably because the fragmented packets get caught somewhere. My guess is that on the versions which work, the initial window size is larger, allowing these sites to respond. The solution in this case would be to fix the remote sites It looks like no matter what I set tcp_rmem to, the window size is always down around 5K on 10.2, which to me looks like a bug as well, so a fix for this would also be a part of the solution -- 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, or are watching someone who is.

The big difference between 10.1 and 10.2 kernel is, that the default /proc/sys/net/ipv4/tcp_rmem [2] sizes are much larger 10.1 has 131072 10.2 4194304 which result in a shift.cnt of 2 in 10.1, 7 in 10.2. For me marymount.edu works if I do a echo "4096 16384 131072" > /proc/sys/net/ipv4/tcp_rmem In leave /proc/sys/net/ipv4/tcp_window_scaling on.

But in general, higher window offers via window scaling option is not a brand new feature, the RFC is from 1992. If the site don't support it, it should not offer the window scaling option in its SACK. That the problem was hidden up to now was pure luck because we never allow so high windows before, the higher window should help for high performance in the local network and so I think it's a good default, all newer kernel have it. Without knowing what exactely cause the problem I don't think that I can convince the netdevel people to change the current default. I see the same problem with vanilla 2.6.19 and the config from comment #12 so I do not know why it did work on Felix machine, maybe some other things influence the setup. Felix how much memory do you have in this machine ? Can you retest with your kernel from comment 12 and if it still works do a tcpdump ? (e.g. tcpdump -i eth0 -vv -n -l host www.marymount.edu |tee mary.log).

https://bugzilla.novell.com/show_bug.cgi?id=229848 ------- Comment #24 from okir@novell.com 2007-01-05 07:21 MST ------- John, this is a problem we can do little about. This is neither a bug in our stack nor in the destination system's stack - I assume there's a connection tracking router/filter at the remote site that does not understand window scaling. This problem has been cropping up for quite some time on the netdev mailing list and in other places. Essentially what happens is that the router happily passes all TCP options during the SYN handshake, including the options announcing window scaling. However, the router doesn't understand window scaling, so when it sees the Linux client announcing a window of "47" (which is really (47 << some scaling factor), it will discard any packets that are not fully inside that 47 byte window. When the stack announces different windows which (scaled or unscaled) are large enough, you will not see any connection hangs (but the download may be rather slow). The fact this issue didn't show up with 10.1 is more of a coincidence, I suspect - the window size announced by the stack depends on lots of factors, including the rmem values and your amount of physical RAM. There's really nothing we can do about this, short of turning off window scaling globally for all peers. The only thing you can do is turn off window scaling locally.

Thanks Slawek for writing the first version, but it seems that he refer to the wrong description. It is not related to TCP fragmentation. Olaf gave the correct description in comment #24.

ipaddress is the address of the affected site.
Note that this also affects 10.1..... -- 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, or are watching someone who is.

It's not even close to just a Firefox problem. Wget and other web browsers suffer too. I have my doubts that most users will recognize the problem and seek out the workarounds. IMO this bug should remain open until something better than obtuse workarounds materializes. Has anyone looked to see if Fedora is doing anything about this, and if so, what? -- 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, or are watching someone who is.

However, I think the article was already fine before since it's scope is much wider than just concerning web browsers (or firefox for that matter). That's why it said "Establishing a connection, e. g. by accessing a particular website ..". Have a look at the title of the article. It is "Problem with establishing TCP/IP connection in openSUSE 10.2" -- 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, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=229848 ------- Comment #42 from mrmazda@ij.net 2007-01-28 23:46 MST ------- Replacing "Firefox" with "web browser" helped, but there's still room for improvement. It's currently written in Geek for Geeks. Normal web users' browsers "can't reach page" or "can't load page", not "can't establish connection". "waiting for www.marymount.edu" means a connection has been been initiated, but that it never changes means that existent connection is somehow defective. The grammar is poor too. If I was the author, I would replace "Establishing a connection, e. g. by accessing a particular website with a web browser, can be failed in some cases on the default installation of openSUSE 10.2." with "Establishing a connection, e. g. by trying to reach a particular website with a web browser, can in some cases fail, using the default configuration of openSUSE 10.2, and other Linux distributions using 2.6.18 or newer kernels." The current reading without the last clause above that I would include might lead one to believe this problem is exclusive to SUSE. -- 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, or are watching someone who is.

I don't want to sound like a walking advertisement, however as there is been no major constant with the above issue, in respect to comms hardware, I think here lies the issue. Some user reply not having an issue, however in respect to all other considerations to the bug, I think we must all state the comms hardware we are seeing this issue reliably demonstrated in AND their ISP. I mention the ISP as I have had major issues with at least 2 ISP's in THEIR ability to resolve any DNS if you are reliant in this respect. -- 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.
