Excuse me maybe I've been on the moon for last few years - is NX or data execution protecion enabled by default in "production" kernels that come with stable distribution (i.e. last Slackware) or do I need to compile the kernel for myself to enable it ? Classical shellcodes executed from the stack seem to not work any longer, even with _va_space_randomize_ switched of - or I'm just to wooden-headed to do that / to desperate ?
