Module Build Guide

We assume you already know how to build your kernel

Building the module

  1. Clone this repository.

    Navigate to drivers directory in your kernel sources e.g. src/linux-5.9.1/drivers and copy directory proc-integrity from this repository there.

  2. Navigate up to src/linux-5.9.1/drivers.

    Edit Kcofig. Add the following line:

    source "drivers/proc-integrity/Kconfig"

    before endmenu

    Edit Makefile. Add the following line:

    obj-$(CONFIG_PROC_INTEGRITY) += proc-integrity/

  3. With the O parameter specifying your kernel build location, run the following command:

    $ make O=/path/to/build/linux-5.9.1 menuconfig

    A menu will pop up. Find and enable the following options as built-in (*), not module (M):

    • PROC_INTEGRITY (Device Drivers -> Simple process integrity checker)
    • CRYPTO_STREEBOG (Cryptographic API -> Streebog Hash Function)
    • KPROBE_EVENTS (Kernel hacking -> Tracers -> Enable kprobes-based dynamic events)
    • DYNAMIC_FTRACE (Kernel hacking -> Tracers -> Kernel Function Tracer -> enable/disable function tracing dynamically)

    Close the menu with saving configuration.

  4. Build the kernel: make O=/path/to/build/linux-5.9.1/ -j4. Parameter j stands for thread count.

Using the module

Just run your the kernel. You should now see integrity check results at regular intervals.
