About Linux Kernel Debugger and Security Certification (LFD440)


This instructor-led Linux Kernel Debugger and Security Certification will teach you the basic methods for debugging and controlling the kernel and how security features are implemented and managed.

This course is intended for advanced developers who need to learn the processes and internal infrastructure of the Linux kernel.
You will leave this course with a solid knowledge of the Linux kernel, debugging methods, and tools.

WHAT YOU WILL LEARN


This four-day Linux Kernel Debugger and Security program provide comprehensive hands-on activities and tutorials to provide you with the skills you need to build and debug Linux kernel code.

THE LINUX FOUNDATION CERTIFICATION VERIFICATION TOOL


Individuals who achieve Linux certification represent the best talent available and have the skills required to perform challenging real-world tasks under time constraints. This verification tool allows you to confirm the validity of the certification. Credentials can also be verified by potential employers to confirm competencies gained. 

Why learn Linux from The Linux Foundation?


  • The Linux Foundation is the best place to learn about all aspects of Linux and other open source technology.
  • The Linux Foundation is a non-profit organization that unites the world’s top developers and companies to construct ecosystems that promote the usage and development of open technology.
  • There are continuous updates to the Linux Foundation’s training to make sure that the most up-to-date knowledge is taught. Training courses offered by Linux Foundation Training are the only ones that can be used on any Linux distribution, making us a standout among our competitors (including RedHat, Ubuntu and SUSE).
  • Because the Linux Foundation does not make any money from the sale of software or support services, there are no hidden costs in the training materials. Only one purpose is to assist students to learn the subject.
  • Instructors at The Linux Foundation are experienced with all major Linux systems and can answer students inquiries about them. You’re learning from people who know what they’re doing!
  • By obtaining Linux Foundation certification, you demonstrate your knowledge and show yourself as competent to your employer and coworkers.

Linux Components

From a debugger’s perspective, a Linux system is made up of the following:

  • The Linux kernel
  • Kernel modules
  • Threads and processes
  • Colleges and Universities (shared objects)

In addition, we may distinguish between two distinct areas in which the code that was executed was performed:

  • Preferential access to the kernel’s privileged area
  • Processes, threads, and libraries all fall within the purview of the user-space portion of the operating system.
  • The user should load the vmlinux debug symbols in TRACE32. In the debug symbols,
  • Automatically loading kernel modules, processes and libraries is done by the TRACE32 Autoloader. P

The Linux Kernel

In a Linux system, the Linux kernel is the most crucial component. It manages the initialization of hardware, device drivers, process scheduling, interrupts, and memory management in privileged kernel space. When the Linux kernel is built into an executable file, it is usually referred to as a “statically linked executable.”

Linux (e.g. “vmlinux”). There is a compressed binary version of the kernel available (zImage/uImage). Inevitably,

What are the Kernel threads?

Having the kernel conduct tasks in the background is often beneficial. This is accomplished by the kernel using Kernel threads. Kernel threads can only be found in the operating system’s kernel. There is a big distinction between kernel threads and other threads in the system.

In contrast to processes, kernel threads do not have their own address space and function inside the context of the kernel. Software packages known as kernel modules (*.ko) are dynamically loaded and linked into the kernel while the computer is running.

A user shell can load and unload them from the kernel using the following commands: modeprobe/insmod and rmmod.

Code for device drivers, file systems, etc. is often found in kernel modules. The privileges of the kernel are granted to the modules that reside in the kernel (supervisor).

The Linux Awareness

In order to debug an operating system like Linux, the debugger has to be specialised. The debugger must be “aware” of the operating system, as the term implies. This particular support for TRACE32 is not statically linked in the debugger programme since it supports a broad variety of target operating systems.

Dynamically installed as an extension for each platform. In addition to these options, debugging the operating system will be much easier with all of the additional tools and displays that will be made accessible. “Awareness” is the name given to the group of files that provides these operating system debugging features.

The Linux awareness accesses the task list or allows process or module debugging. The internal structures of the kernel are represented using kernel symbols. The kernel symbols must be accessible at all times, therefore. Linux-aware debugging will not be feasible till this is addressed. A compiler must be used to build the file vmlinux.
