Hi! You can find an implementation of stackgap from OpenBSD at http:// people.freebsd.org/~ssouhlal/testing/stackgap-20050527.diff You can control the range of the random stack gap with the kern.stackgap_random sysctl. A value of 0 disables it. Otherwise, it has to be a power of 2 and not too large. The default value is 64K. I've only had the chance to test this on i386. Could anyone test it on other architectures as well? Any comments/objections? -- Suleiman Souhlal | ssouhlal@vt.edu The FreeBSD Project | ssouhlal@FreeBSD.org
