Hello List, I was thinking about writing some memory R/W access monitor. The only concern I'm having is whether it is doable, or are there any already existing and working solutions like that for Linux? The initial concept was to set up some special page fault handler and mark monitored memory pages as non present. The monitor pagefault handler would check if the page is within monitored location and if yes it would switch to singlestepping mode and step the instruction which invoked the pagefault and log the value which was read/written from certain address. Afterwards the whole page would be marked as non present again. Is it possible to succeed with such an approach? Would it work for memory range mapped to some devices? kind regards, Mateusz Berezecki - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
