Linux Dynamic Debugging

-
In Linux programming, it is very important to debug your code by adding some debug messages to your code.

By using the dynamic debug feature of Linux, you can enable these debug messages per file, per function and even per line. 

This post will show you how to do this with a simple kernel loadable module implementation.

First, you need compile your kernel with the CONFIG_DYNAMIC_DEBUG option. It is under "Kernel hacking" menu and prompt name is "Enable dynamic printk() support" as you see on the below screenshot.




Sample Code:

Enable/Disable dynamic debug in the sample code:

How to Use container_of in Linux Kernel Development

-
In this post, I will explain the usage of linux's container_of macro with a sample code. If you know address of a data structure's field, you can get the address of the instance of that data structure by using the container_of macro. This is the simplest explanation of this macro. Let's say you have a function called with a pointer parameter and you know that the pointer is pointing an address of a data structure field. struct my_object { int a; int b; } obj; function(&obj->b); If you want to access the other field "a" in the function, you need to use container_of macro. Let's see the below sample code and it's output to understand it easily. /* * my_object structure. */ struct my_object { int a; int b; int c; }; /* * container_test() * Test function for usage of container_of macro. * * This function is passed a pointer which points a field of * an allocated my_obj...

Notification Chains in Linux Kernel

-
Notification chains in Linux kernel is a mechanism for the subsystems being informed by the events generated by the other subsystems. In other words, if you are developing a new driver in Linux and you want to listen some events from other driver and handle these events in your own driver, you need to use the Linux's notification chains mechanism. As an example, if you develop a driver and this driver needs to be informed about the net device events such as net device UP, DOWN events, the driver needs to register itself to the net device notifications with the  register_netdevice_notifier function. Similarly, it unregisters itself with the unregister_netdevice_notifier function. These functions are provided by the net device subsystem. The APIs and the data structures of notification chains are defined in the include/linux/notifier.h and  kernel/notifier.c files under linux source code. In this post, I am going to explain how this notification chains mechanism wo...
