2c75421 by Guy Harris (guy@xxxxxxxxxxxx):

    Use wmem_memdup() instead of wmem_alloc() followed by memcpy().
    
    This also fixes a case where, if nfs_fh->len wasn't a multiple of 4, the
    allocated buffer was too short, by the difference between the next lower
    multiple of 4 and nfs_fh->len, so the memcpy() went past the end of the
    buffer.  (And, yes, an NFSv3 file handle can have a byte count that's
    not a multiple of 4 - it's a variable-length opaque type - even if the
    marshalled data is padded with 0s to a multiple of 4 bytes, as with
    other XDR types.)
