In sysctl(8), you can set an integer type, but the max value an int can be is 2 * N-1 where N is the size of int. This leads to a problem when trying to set kern.hostid and the number is greater that 2GB on an IA32 system. So my question is should CTLTYPE_INT be treated as a long or some other larger numeric number? Or should we declare some CLTYPE_UINT type? If there is going to be overflow, should it not be because of the sysctl being set and not because of the sysctl(8) causing it? See PR kern/21132 for an instance. - JimP -- --- @(#) $Id: dot.signature,v 1.10 2001/05/17 23:38:49 Jim.Pirzyk Exp $ __o Jim.Pirzyk@disney.com ------------- pirzyk@freebsd.org _'\<,_ Senior Systems Engineer, Walt Disney Feature Animation (*)/ (*) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-arch" in the body of the message
