Hi Linus, Andrew, Kernel 2.6 lacks two -EFAULT returns in get_user() in kernel/sysctl.c. It's already fixed in 2.4 9 months ago, but I forgot to send it for 2.6. It's basically this one: http://linux.bkbits.net:8080/linux-2.4/diffs/kernel/sysctl.c@1.23?nav=index.html| src/|src/kernel|hist/kernel/sysctl.c Please apply. ciao, Marc
