Linux Kernel Network Programming – dst_entry data-structure – Introduction and code-walk
dst_entry() is one of the important Linux Kernel Networking subsystem data-structure which is used while navigating the packet flow within the IPv4 stack. It contains function pointers one for input…
Linux Kernel Programming – Kernel Interfaces #kernel #linux #coding #kirankankipati #training
As I discussed in various episodes and articles in the past there are various ways via which you can communicate from Kernel space to User space and vice-versa. Some of…
Linux Kernel Driver Device Trees #programming #linux #kernel
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,…

Research Socket overhead in Linux vs Message Queues and benchmarking #ipc #benchmarks
The objective of this research is to assess the system performance overheads of user-space sockets (in this case UDP sockets) vs Message queues. So that this can be used as…
Code with Kiran – Live Coding – Linux Kernel Programming – Kernel Libraries #coding #demo #kernel
In the case of user-space programs, we use third-party libraries (explicit or implicit), but that cannot happen when you code in kernel space. The libraries share the same address space…
Compiling a C Compiler with a C Compilter – Compile gcc with gcc
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…
Circular Ring Buffers Live Visual Demo – Linux Kernel – Device Drivers – Network Stack
In the past I discussed in depth about Architecture and big-picture of Circular Ring buffers and its significance which you can go through over HERE. Here I did a live…
Circular Ring Buffers Architecture – Linux Kernel – Device Drivers – Network Stack
A circular buffer, circular queue, cyclic buffer or ring buffer is a data structure is a fixed-size buffer as if it were connected end-to-end or can be a dynamic one…
