Kernel module for probing cr3
Extracted from old student code for Virtual Machine-Provided Context
Sensitive Page
Mappings, from way
back. This project simply defines a kernel module that allows probing the
process's cr3 register (i.e., the page table base register) via character
device.
Usage
Requires, of course, Linux kernel headers for LKM development. Building & installing the module are straightforward:
make
insmod ./cr3spy_mod.ko
mknod /dev/cr3spy c 200 0
The probe subdirectory reads the cr3 register value via the character device
and writes it to stdout.
