Hi, I inspect my Linux memory, and it seems that there is no area that prohibite execution like I expected (using NX bit in modern CPU). That really surprises me. I looked at some potential data areas exported in System.map file, like: - mark_rodata_ro - sysctl_data - new_cpu_data - boot_cpu_data And all of these areas allow to execute code (because NX=0 there). Is that really desirable? Anybody know for sure which area (easier to check if exported in System.map) doesnt allow execute? I can confirm that NX is active in my machine (reported in dmesg) Thanks, H -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
