OpenBSD/src xNmnEUM — sys/conf param.c, sys/kern uipc_mbuf.c kern_sysctl.c
Prevent integer overflow in kernel and userland when checking mbuf limits. Convert kernel variables and calculations for mbuf memory into long to allow larger values on 64 bit machines. Put a range check into the kernel sysctl. For the interface itself int is still sufficient. In netstat -m cast all multiplications to unsigned long to hold the product of two unsigned int. input and OK visa@
