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…
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…
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,…

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…
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…
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…
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…
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…
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…
