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…
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…
Roadmap – How to become Linux Kernel Developer – Device Drivers Programmer and a Systems Software Expert #classes #courses
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 here is my YouTube video…
Linux Kernel Programming – atomic_t datatype – atomic variables and APIs #programming #kernel #linux
If you allocate any global variables and when you access them (i.e read or write) at different parts of the code you are supposed to use locks such as Spinlocks,…
