For the record, I have been running linux-image-2.6.24-24-generic version 2.6.24-24.54 from hardy-proposed on my primary x86-64 workstation for the last two weeks. In that time I haven't experienced any of the NFSv4 hang-ups that I was previously observing, and no instances of the kernel BUG backtrace appear in the logs. -- kernel bug rpc nfs client https://bugs.launchpad.net/bugs/212485 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 212485] Re: kernel bug rpc nfs client
Hi, I'm using this kernel on my workstation now for 2 days, and I haven't seen the crash since. Disconnecting the network cable doesn't seem to crash my system, I get nfs server timed out, still trying messages and after plugging the cable back in, the system comes back online after some time. So, it seems to work fine for me. Below are the last lines from dmesg as i plugged the cable back in. Confusingly, my nfs server is called server, but the log message displays it as serve, just like it did with previous kernels. It doesn't seem to cause problems however, and later kernels have a fix for this.

[Bug 212485] Re: kernel bug rpc nfs client
Hi all, I've been hit with this bug also, and I've found a relatively reliable way to reproduce it. - desktop system mounts /home/ with nfs4 - login with gdm, start firefox and do some browsing, by entering some urls in the location bar - issue some find /home commands - unplug the network cable This wil crash the kernel within a few minutes, for me, on two different systems. Maybe not all steps are needed, logging in and using firefox certainly is necessary. It seems that the file locking that firefox uses for a lot of database files helps in reproducing the problem. I've also recompiled the ubuntu kernel with the patch mentioned by Daniel Blueman. This was a bit harder then I imagined, I got some rejects and had to fix that manually. However, with the patched kernel I was unable to reproduce the kernel crash. Finally, I've installed the Jaunty kernel, and haven't been able to reproduce the bug with it. The jaunty kernel also has an updated rpcb_clnt.c file.

For this to happen, it suffices for a _parent_ rpc_clnt to use autobinding, in which case any clone may find itself triggering the !xprt_bound() case in call_bind(). The correct fix for this is to walk back up the tree of cloned rpc clients, in order to find the parent that 'owns' the transport, either because it has clnt-cl_autobind set, or because it originally created the transport...

I am currently trying to setup a Sun Fire X4600 with Hardy/Server and this is actually the latest and most important of three show-stopper Kernel-related bugs I've encountered so far. All of them are known for some month now, and all of them seem to be related to 2.6.24 only.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel.

I'm backtracking w/my last statement a bit. Looks like the 2.6.24-11 kernel doesn't exhibit these problems as well and on top of that I've had zero problems (knock on wood) with the forcedeth driver and this kernel. Yesterday I was able to reliably generate the kernel Oops noted above AND crash my NIC by doing 2-3 large dd's plus a bonnie++ in less than 15 minutes. I've been running the same regression against -11 for almost 2 hours without any problems. I'm still working on git for -12 through -14 but just a FYI about -11. -- kernel bug rpc nfs client https://bugs.launchpad.net/bugs/212485 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 212485] Re: kernel bug rpc nfs client
I'm doing a git (as we speak) between 2.6.24-12.18 and 2.6.24-14-25 on my Ubuntu Hardy system. I'm assuming for the moment that 2.6.24-12.18 is a known good version of rpcb_clnt.c. In addition, I'll be installing a 2.6.26 kernel + patches from source on my system and retesting. In the meantime are we certain that there is not another issue in play? For instance, in my case, I'm running on a Sun x4100 so this means I have a nForce NIC and use the forcedeth driver. Periodically my NIC will go vegetative and instance is denoted with messages like: Jul 31 12:53:16 prod-unix-shell04 kernel: [ 596.950188] nv_stop_tx: TransmitterStatus remained busy6eth0: link up. When this happens my system will fall of the network until it is power cycled -- as using ifup, ifconfig, or even a reboot doesn't set the NIC straight. Sometimes this happens when I'm using NFSv4 and sometimes this happens when I'm not. It always happens when I'm doing lots of I/O (apt, bonnie++, SQL queries, dd, etc.). Given what's been described here earlier (RE: pulling network cable and watching nfsv4 go haywire) I'm curious if the problem is not limited to changes to rpcb_clnt.c.

Hi Daniel, Thanks for all of your updates and feedback. You mentioned you do not witness this bug with a 2.6.25 kernel. I just wanted to let you know that the Intrepid Ibex 8.10 Alpah3 release most recently came out and it is based on a 2.6.26 kernel - http://www.ubuntu.com/testing . You may want to give that a test just to verify we will not see this in the upcoming release.

I have found this reproduces when you have an active NFSv4 mount (eg /home) and bring the ethernet interface on the client down, eg unplug the cable. -- kernel bug rpc nfs client https://bugs.launchpad.net/bugs/212485 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

There are only two sites where cl_parent is assigned in the kernel tree, and it's assigned to 'clnt', so the only time this BUG_ON will fire is when there is memory corruption or use-after-free (less likely). -- kernel bug rpc nfs client https://bugs.launchpad.net/bugs/212485 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 212485] Re: kernel bug rpc nfs client
I experience this every ~5th shutdown, however the stack trace I see is: rpcb_getport_async rpc_malloc call_bind call_reserve __rpc_execute ... which corresponds to rpcb_clnt.c:322: BUG_ON(clnt-cl_parent != clnt); This is called from a kernel thread context and I only see the bug_on trigger when shutting down, where NetworkManager cutts the ethernet connection before NFS is unmounted (yikes). -- kernel bug rpc nfs client https://bugs.launchpad.net/bugs/212485 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
