Xi Wang ba1cffe025 ax25: avoid overflows in ax25_setsockopt() ... Commit be639ac6 ("NET: AX.25: Check ioctl arguments to avoid overflows further down the road") rejects very large arguments, but doesn't completely fix overflows on 64-bit systems. Consider the AX25_T2 case. int opt; ... if (opt < 1 || opt > ULONG_MAX / HZ) { res = -EINVAL; break; } ax25->t2 = opt * HZ; The 32-bit multiplication opt * HZ would overflow before being assigned to 64-bit ax25->t2. This patch changes "opt" to unsigned long. Signed-off-by: Xi Wang <xi.wang@gmail.com> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.
