Re: [suse-security] Bug in nfsd from kernel

I would call his bug, a bug and a denial of service that any
user could trigger.

I thought this list was for SECURITY issues, which is why I subscribed to it. Aren't there any other lists for discussing normal system bugs that this sort of traffic should go to?

I find a lot of unnecessary chatter on non-security issues. I really hate to censor anything, but on these lists that aren't moderated (presuming that it's not monitored) sometimes discussions get carried away.
Just thought I would raise the point.

[suse-security] Bug in nfsd from kernel


I discovered a bug in the nfs daemon delivered with the kernel update to

When accessing a large amount of files over an nfs export from a machine
with SuSE 10.1 and kernel, stale NFS handles occur. After
a short period (3-5s) the files are accessible again. "grep -R hello" *
triggers the bug for example.

My configuration:
SuSE 10.1 with kernel, NFS export of an XFS filesystem
mounted on different clients with autofs (UDP and TCP).

Degrading back the kernel to and all works fine again.
