  • [+] pink/purple box(es) are the additional helper APIs (which are not as critical as those yellow ones)

Quagga Routing Suite - OSPF, RIP, RIPng BGP4 | GNU Zebra fork | ZebOS ↗
Saturday' 13-Mar-2021
GNU Zebra is one of the oldest open-source Dynamic Routing Protocol suite stack developed by Kunihiro Ishiguro. Zebra supports features such as RIPv1/RIPv2 for IPv4 and RIPng for IPv6, OSPFv2 and OSPFv3, BGPv4+ and so on. Zebra is an active project for many years. After many years of active support Zebra is discontinued, and sometime down the lane a new fork is created from Zebra called Quagga which is now maintained by a separate independent open-source community. Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPng and BGP-4 for Unix platforms, particularly FreeBSD, Linux, Solaris and NetBSD. Quagga is a fork of GNU Zebra which was developed by Kunihiro Ishiguro. The Quagga architecture consists of a core daemon, zebra, which acts as an abstraction layer to the underlying Unix kernel and presents the Zserv API over a Unix or TCP stream to Quagga clients.

What is purpose of Kernel Development - Example SMOAD Networks SDWAN Orchestrator Firewall Kernel Engine ↗
Monday' 18-Jul-2022
Often aspiring students may have this question, that what is the purpose of Linux Kernel Development. Since Linux Kernel is very mature and it has almost everything one would need. Usually, we need custom kernel development in the case of any new driver development for new upcoming hardware. And this happens on and on. But at times we may also come across few features/modules/components which are already provided by the Linux Kernel which are not adequate or atleast not the way we exactly intended to use. So, this is the real-world example, sometimes no matter what Linux Kernel provides as a part of stock Kernel/OS features, sometimes we have to write our own custom kernel stack or module(s) which can specifically cater our exact needs.

Roadmap - How to become Systems Software Developer ↗
Friday' 13-May-2022
When you are at the beginning of your career or a student, and aspire to become a software developer, one of the avenues to choose is to become a hard-core Systems Software Developer. However it is easier said than done, since there are many aspects to it as you explore further. As a part of systems developer, you can get into core kernel space developer, kernel device drivers developer, embedded developer and get into things like board bring-up, porting, etc, or can become a user-space systems programmer, and so on. So here is my detailed multi-episode Youtube video series on Roadmap - How to become Systems Software Developer.

Linux Kernel vs User-space - Library APIs - Linux Kernel Programming ↗
Tuesday' 17-Jan-2023
One of the important aspects a beginner who is into Linux Kernel space systems software development has to understand is that unlike user-space C/C++ programming, where you can freely include any library APIs via respective #include files (which are dynamically linked during run-time via those /lib .so files), in the case of Kernel space programming, these library APIs are written within the Kernel source itself. These are the fundamental APIs which we commonly use, such as memcpy(), memcmp(), strlen(), strcpy(), strcpy() and so on. So here is my detailed Youtube video episode on the same with live demo, walk-through and examples.

Linux Kernel Driver Device Trees ↗
Tuesday' 17-Jan-2023
The Linux kernel is the backbone of the Linux operating system. A device tree is a hierarchical tree structure that describes the various devices that are present in a system, including their properties and relationships to one another. The device tree is used by the Linux kernel to identify and initialize the different devices on a system, and to provide a consistent interface for interacting with them.

Linux Kernel /sysfs Interface ↗
Saturday' 14-May-2022
/sysfs is one of the most popular kernel to user-space interface which you can leverage to add an interface to your Kernel code such as Kernel modules, Kernel Device Drivers, etc. Although personally I prefer /proc interface than other alternatives such as /sysfs, ioctl() and so on for my personal Kernel modules/stack. So here is my detailed multi-episode Youtube video series on /sysfs Interface.

Linux Kernel Data-Structures ↗
Saturday' 13-Mar-2021
Here is a quick reference of important Linux Kernel Data Structures of various assorted Kernel Subsystems such as: Process, Memory Management, Networking, File System, Device Drives, IPC and so on. So when you write custom Kernel code, it is often you may need to populate a new instance of one of these data-structures or just access the existing ones. Hence it is very important to know some of these and get familiarized with. You can bookmark this page, so that you can use this as a quick reference when you write your own custom Linux Kernel Modules.
