Nice, but: "Since 2.6.23, it has been possible to prevent applications from mapping low pages (to prevent null pointer dereferencing in the kernel) via the /proc/sys/vm/mmap_min_addr sysctl, which sets the minimum address allowed for such mappings." 2.6.23 released: Tue, 9 Oct 2007 Ref: http://lkml.org/lkml/2007/10/9/241 http://james-morris.livejournal.com/26303.html -- JS
