Colin Ian King 3457ba1ace fs/ufs: avoid potential u32 multiplication overflow ... [ Upstream commit 88b2e9b063 ] The 64 bit ino is being compared to the product of two u32 values, however, the multiplication is being performed using a 32 bit multiply so there is a potential of an overflow. To be fully safe, cast uspi->s_ncg to a u64 to ensure a 64 bit multiplication occurs to avoid any chance of overflow.
