I am having a somewhat weird problem with nfs locking.  My servers are
linux version 2.4.21.  The server filesystems are xfs.  My clients are
HPUX 11i and linux(tested with 2.4.21 and 2.4.25 stock kernels).
When I try to use fcntl, the HPUX client will always fail to lock unless
the file is world readable.  Even if the user is the owner with rwx, the
lock will fail.  As soon as I chmod a+r on the file, the lock will
succeed.
On linux clients, I have not been able to get the file to lock at all.
The fcntl returns EBADF which implies I passed a bad file descriptor, but
I have verified that it is a valid file descriptor.
Are there any issues with the linux NFS locking code that I am obviously
overlooking?  I know in the past there was some discussion about some
locking techniques that were supported or not supported.  Am I facing one
of these?
Thanks.
