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…
libpcap Library – Linux User-space Network Stack Development
libpcap is a very popular user-space networking library, with which you can capture and or generate packets. libpcap is the underlying framework for many popular packet capture tools such as…
Linux Kernel Programming – Kernel Source-code Porting – Introduction #kernel #linux #coding
At times you may come across some old or legacy kernel source-code which could be something you stumbled across online open-source code or it could be your organization proprietary code…
Linux Kernel-Space Socket Programming – Introduction #kernel #linux #networking
Usually as a part of network software development you do socket programming. But this is typically done in user-space, where the user-space socket APIs takes the instructions (via socket API…
Using a GPS Sensor #IoT #GPS #ArduinoUNO #Skylab-SKG13BL
A GPS receiver uses satellites to pinpoint locations, so as long as you have a GPS receiver and a clear view of the sky, you'll never be lost again. So…
VPN Stack Architecture – Linux Kernel Virtual Network Interfaces – OpenVPN – Wireguard – VTun – IPsec
Every VPN stack is architecture is done in a specific way to accomplish fundamental VPN specifications, requirements and goals. As a part of VPN Network stack architecture quite often we…
