BugID's fixed with this patch: 1026933 1034007 1039977 1029628 1037476 1038327 1038302 1034328 1045536 1045993

Obsolete By: 5.0

Problem Description:

BUGID:1026933
        Pages (not just bytes) of one file appear in another.
 Only happens
        on client; file on server OK.  Goes away when you reboot.

BUGID:1034007
        getdents system call (used by ls command) was not returning
        all directory entries.


BUGID:1039977
        When the kernel is built with the NFS debugging options the resulting
        kernel panics due to a bug in the nfs debugging code.
 I also suspect
        that it would panic if you compiled the kernel with the trace option
        on.


BUGID:1029628
        When a program with the setuid bit set is copied between local files
        the setuid bit is cleared.  If the same file is copied to an nfs
        file system the setuid bit is not cleared on the new file.     

BUGID:1037476
        Sending bad procedure number to NFS server can cause mbuf leak.

BUGID:1038327
        NFS write transfer sizes are not being restored after
being reduced
        by the NFS dynamic retransmission feature. 

BUGID:1038302
        NFS export option "anon=-1" does not work.  The user will not
        be allowed to mount the exported filesystem.


BUGID:1034328
        An NFS client can crash if two procedures unlink the same file at
        once.

BUGID:1045536
      NFS exports to non-sun systems can allow file truncation (security
      violation).
       
BUGID:1045993
     NFS attribute problem on locked files over nfs results
in read error.
