Bug Description

When accessing nfs4 mounts I get kernel 2 Oops.

On the server I am running the latest feisty version:
ii nfs-common 1.0.12-4 NFS support files common to client and serve
ii nfs-kernel-ser 1.0.12-4 support for NFS kernel server

On the client I am running the latest gutsy version:
ii nfs-common 1:1.1.1~git-20070709-3ubuntu1 NFS support files common to client and server
ii nfs-kernel-server 1:1.1.1~git-20070709-3ubuntu1 support for NFS kernel server

The Oops does not happen after the mount, but after some random read / write time using the share.

same result with nfs3 and sec=krb5. mount worsk, but any access to the mount crashes the caller with a similar call trace to above.
I also replicated the nfs4 crash.

In nfs3 the keytab is optional, and the I can get immediate segfaults without the keytab in place.
My log output always seems to end with a line about auth_rpcgssd.

at least you guys get as far as getting a kernel oops :) on my gutsy box i can't even succesfully mount my nfs shares served by a debian etch server, i get a permission denied error, see this post here:

http://ubuntuforums.org/showthread.php?t=570320

works nicely on feisty though, i fear there's been some major upstream change that broke backward compatibility

Hi,

I'm running a machine that mounts nfs4 over a openvpn tunnel automatically on startup.
I am running gutsy I just updated to the 2.6.22-14 kernel, there was no problem before.
Now the machine crashes each time I try to mount my nfs4 share.
What makes this bug even worse is that after the nfs4 BUG occurs, my keyboard and mouse are frozen.

I experience the same problem described above by AZ with the newest Gutsy kernel (2.6.22-14.47, 18 dec 2007)
My setup (Dell Inspiron Desktop 531s) has been stable since I've upgraded from Feisty last month.
I mount three nfs v4 shares from a Fedora 7 server (from my /etc/fstab), and the kernel crashes at the same point. GDM executes but neither the mouse nor the keyboard works. The workstation boots fine when I comment the three NFS mounts in /etc/fstab.

From my /var/log/kern.log:

Oops - forgot to repost to this bug when I found out what's going on.

Two bugs that gave me kerberized nfs problems have been fixed upstream.
To my usterstanding; one was kerberos attempting to negotiate an unsupported enctype, which triggered a second kernel bug causing the kernel oops.

The workaround for me was to set default enctypes in the krb5.conf file

default_tkt_enctypes = DES-CBC-CRC
default_tgs_enctypes = DES-CBC-CRC

Thanks James.

However, I must say that I don't use kerberos with NFS4, so maybe the problem lies elsewhere.

Claude and AZ,

The problem you are experiencing is in fact (embarrassingly) caused by my patch at https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/164231 which was included in the 2.6.22-14.47 kernel as part of a security update. This problem is unrelated to the OOPS that was originally reported by Marcel in this bug. For more details on your problem, and hopefully a fix soon, see my explanation here: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/164231/comments/15 and watch that bug for updates.

Thanks,
Philip

Copying the pre-compiled nfs.ko file provided above worked for me. Note
that it's for the -generic kernel, not the -i386 which was the default
on my machine.
