From 402af595bcaa120a104360ebebeb3d8f5eac8859 Mon Sep 17 00:00:00 2001 From: Theo de Raadt Date: Wed, 15 Oct 2008 23:23:52 +0000 Subject: make random(9) return per-cpu values (by saving the seed in the cpuinfo), which are uniform for the profclock on each cpu in a SMP system (but using a different seed for each cpu). on all cpus, avoid seeding with a value out of the [0, 2^31-1] range (since that is not stable) ok kettenis drahn --- sys/arch/vax/include/cpu.h | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'sys/arch/vax') diff --git a/sys/arch/vax/include/cpu.h b/sys/arch/vax/include/cpu.h index a7af7b5a25c..68e9478ee17 100644 --- a/sys/arch/vax/include/cpu.h +++ b/sys/arch/vax/include/cpu.h @@ -1,4 +1,4 @@ -/* $OpenBSD: cpu.h,v 1.32 2008/10/10 08:36:28 art Exp $ */ +/* $OpenBSD: cpu.h,v 1.33 2008/10/15 23:23:50 deraadt Exp $ */ /* $NetBSD: cpu.h,v 1.41 1999/10/21 20:01:36 ragge Exp $ */ /* @@ -54,6 +54,7 @@ struct cpu_info { struct proc *ci_curproc; struct schedstate_percpu ci_schedstate; /* scheduler state */ + u_int32_t ci_randseed; }; extern struct cpu_info cpu_info_store; -- cgit v1.2.3
