    Description

      u64 lov_stripe_size(struct lov_stripe_md *lsm, int index, u64 ost_size,
                    int stripeno)
{
        u32 ssize = lsm->lsm_entries[index]->lsme_stripe_size;
..
        if (stripe_size)
                lov_size = ost_size * swidth + stripeno * ssize + stripe_size;
        else
                lov_size = (ost_size - 1) * swidth + (stripeno + 1) * ssize;

       (stripeno + 1) * ssize operates on 2 32-bit integers and may overflow. For instance if stripeno == 31 and ssize == 128 * 1048576.

      The causes miscalculation of file size.
