Building a comfortable workflow for debugging an old version of the Linux kernel
The article discusses how to set up a debugging environment for an old version of the Linux kernel, specifically version 4.7. It outlines the tools needed, such as Docker for compiling and QEMU for running executables, and provides steps for retrieving and compiling the kernel source code. The author emphasizes the importance of using compatible versions of compilers and tools to avoid compilation errors.
- ▪To debug the Linux kernel, a comfortable working environment is essential.
- ▪Docker is recommended for compiling sources with the correct GCC/LD versions.
- ▪The article provides a step-by-step guide for retrieving and compiling the kernel source code.

I use: Docker for compiling sources in their original version (with the GCC/LD versions corresponding to the source era). QEMU for running the executables in a virtual machine.
