I would call his bug, a bug and a denial of service that any user could trigger. Thanks, LDB Mike Siedelberg wrote:
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.

Subject [suse-security] Bug in nfsd from kernel 2.6.16.21-0.13
Hello,
I discovered a bug in the nfs daemon delivered with the kernel update to kernel 2.6.16.21-0.13.
When accessing a large amount of files over an nfs export from a machine with SuSE 10.1 and kernel 2.6.16.21-0.13, 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 2.6.16.21-0.13, NFS export of an XFS filesystem mounted on different clients with autofs (UDP and TCP).
Degrading back the kernel to 2.6.16.13-4 and all works fine again.
Regards, Marco
