Jeff Layton 8fcd461db7 nfsd: do nfs4_check_fh in nfs4_check_file instead of nfs4_check_olstateid ... Currently, preprocess_stateid_op calls nfs4_check_olstateid which verifies that the open stateid corresponds to the current filehandle in the call by calling nfs4_check_fh. If the stateid is a NFS4_DELEG_STID however, then no such check is done. This could cause incorrect enforcement of permissions, because the nfsd_permission() call in nfs4_check_file uses current the current filehandle, but any subsequent IO operation will use the file descriptor in the stateid. Move the call to nfs4_check_fh into nfs4_check_file instead so that it can be done for all stateid types.
