README.md

A tool for downloading and preparing RHEL-based and upstream Linux kernels.

Usage

./rhel-kernel-get.py VERSION [--output-dir DIR] [--kabi]

Downloads and prepares the given version of the Linux kernel. If the version contains the release part (e.g., 3.10.0-862.el7), it downloads the RHEL (CentOS) kernel, otherwise (e.g., 4.10), it downloads the upstream kernel.

--output-dir specifies the output directory of the downloaded kernel.

Setting --kabi extracts the KABI whitelist (applicable to RHEL kernels only).

Requirements

• kernel build dependencies: gcc, make, bison, flex, libelf-dev (elfutils-libelf-devel), bc, openssl (openssl-devel).
• cpio
• tar, xz, bzip2
• Python 3 packages from requirements.txt

Eg. on Fedora the requirements can be downloaded by following commands:

dnf install gcc make bison flex elfutils-libelf-devel bc openssl-devel cpio tar xz bzip2
pip install -r requirements.txt
