Named for my kernel release. Navigating inside would contain all the header files:ls /usr/src/linux-headers-5.15.0-56-genericarch crypto Documentation drivers fs include init ipc Kbuild Kconfig kernel lib LICENSES Makefile mm net samples scripts sound tools usr virtFurthermore, we can validate the kernel headers actually work by building a simple external module:cd /usr/src/linux-headers-$(uname -r)make -C /lib/modules/$(uname -r)/build M=$PWD modules(module compiler output) This module compiled successfully, proving my headers integrate properly with the current kernel!If you received build errors instead, double check your headers version against uname -r. Mismatches during upgrades can cause issues.Configuring External ModulesNow with functional kernel headers installed, let‘s walk through an example of developing and integrating an external kernel module.This simple "Hello World" Linux module prints a message when the kernel loads it:// hello.c#include #include int init_hello(void){ printk(KERN_INFO "Hello world!\n"); return 0;}void exit_hello(void) { printk(KERN_INFO "Goodbye world!\n"); }module_init(init_hello);module_exit(exit_hello);MODULE_LICENSE("GPL");MODULE_DESCRIPTION("Linux Kernel Module Example");To build the module against the installed headers:make -C /lib/modules/$(uname -r)/build M=$PWD modulesThis compiles hello.c into a loadable kernel object file hello.ko. Next insert the module with modprobe:sudo modprobe hello[ 135.639033] Hello world!And verify it exists within the kernel:lsmod | grep hellohello 16384 0Hurray! Our external module printed to the kernel log. Now remove it:sudo modprobe -r hello [ 148.312922] Goodbye world!This demonstrates the full workflow of utilizing kernel headers to extend functionality!Removing Old Kernel HeadersIf you upgrade to a newer kernel and rebuild modules, the old headers are no longer needed. We can easily remove the old versions:sudo apt purge linux-headers-5.15.0-56Reading package lists... Done Building dependency tree... DoneThe following packages were automatically installed and are no longer required: linux-headers-5.15.0-56 linux-headers-5.15.0-56-generic linux-image-5.15.0-56-generic linux-modules-5.15.0-56-generic Use ‘sudo apt autoremove‘ to remove them.The following packages will be REMOVED: linux-headers-5.15.0-56*After this operation, 82.1 MB disk space will be freed. Do you want to continue? [Y/n] Be sure to run apt autoremove afterwards to clean up unused dependencies.You could even write a script to match and remove old headers automatically whenever your kernel package upgrades!Conclusion: Your Kernel Awaits!And with that, you should have a solid understanding of kernel headers in Linux – what they provide, why you need them, and how to install matching versions for your kernel release.Here‘s a quick recap of the key steps we covered:Use uname -r to find your current kernel release stringCheck for already installed headers with apt search Install headers for kernel with apt install linux-headers-$(uname -r)Verify headers directory exists under /usr/srcConfigure modules to build against headers with makeRemember
