Adding your own Kernel Modules into Linux Kernel Source | Linux Kernel Programming ↗
Thursday' 13-Aug-2020
Whenever you do custom kernel modules, you can optionally make it a part of existing Linux Kernel source. This does not mean you are submitting your kernel module to the mainline kernel source (i.e kernel.org Linux Kernel Foundation). What I meant is, you can make your kernel module(s) part of Linux Kernel source so that when you compile your kernel you can automatically compile your kernel module(s) too. As well when you create/modify kernel .config configuration file (such as via make menuconfig, etc), you can enable or disable your kernel module(s) too.
To do the same you have to register (and include) your custom Kernel Module's Kconfig and Makefile to the existing Kconfig and Makefile of the Linux Kernel source Here is a detailed multi-episode video of mine which gives the overall idea and the big-picture.

Linux Kernel Programming | with or without Kernel Modules | Device Drivers ↗
Thursday' 13-Aug-2020
When learning Linux Kernel programming, often I notice my students and viewers gets confused and they start with learning writing Linux Kernel modules. And so they develop the common misconception about Kernel Programming in general. They assume writing code in Linux Kernel means writing kernel modules. Which is absolutely not. Kernel modules are an optional choice and are part of Linux Kernel. But besides modules, Linux Kernel has lot of other mainstream code. Hence if anyone wants to be a Kernel Developer, you should be aware that sometimes you add new code via modules, sometimes without them. And if you ask me, I am not much in favor of writing Kernel modules. Instead in my code, I try to integrate and make them a part of Linux Kernel so that they all get initialized during boot time. Here is an extensive Youtube video of mine on Linux Kernel Programming, with and without Kernel Modules.

Linux Kernel Module to Drop Packets captured via netfilter hooks ↗
Thursday' 13-Aug-2020
Here is my sample Kernel Module to drop packets (i.e sk_buff instance) captured via netfilter hooks. When you want to drop packets in your custom netfilter hooks make sure you never do a manual kfree_skb(skb) API call. Since it is anyway performed once the flow of the code moves out of your kernel module netfilter hook. All you need to do is to return NF_DROP to drop gracefully the desired packet. Here is my detailed video and a sample Linux Kernel module.

Roadmap - How to become Linux Kernel Developer - Device Drivers Programmer and a Systems Software Expert ↗
Thursday' 13-Aug-2020
Many viewers and even sometimes my students ask me how I can become a kernel programmer or just device driver developer and so on. So I shot this video (and an add-on video) where I summarized steps and a roadmap to become a full-fledged Linux Kernel Developer.

Compiling a C Compiler with a C Compilter | Compile gcc with gcc ↗
Thursday' 13-Aug-2020
The fundamental aspect of a programming language compiler is to translate code written from language to other. But most commonly compilers will compile code written in high-level human friendly language such as C, C++, Java, etc. to native CPU architecture specific (machine understandable) binary code which is nothing but sequence of CPU instructions. Hence if we see that way we should able to compile gcc Compiler source code with a gcc Compiler binary.
