Aim:
Build a kernel module that can list all the process starting from the init process in a DFS(Depth-First-Search) fashion. Load this into the kernel and see the execution.
This process is much easier on the actual Linux OS, however I am doing it on WSL2 and it requires a few extra steps.
Step 1: Build the custom Linux Kernel
The steps to do this is explained in build_custom_kernel.md
Step 2: Test the custom Kernel with a simple hello module
The steps to do this can be found in hello_module.md
Step 3: Proceed with the main aim. Build the module to list processes.
The steps to do this is in process_list.md
Note:
The MODULE_LICENSE describes the license which our module can be used under.
To check the information about a specific module use modinfo <filename>.ko.
