[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
