kconfigs

This is a system for fetching the Linux kernel configuration files for a variety of Linux distributions, and archiving them for later analysis. The resulting configuration data is summarized into a compact JSON file which can be browsed on our webpage. Or, you can simply download the configurations and explore them with grep.

On a regular basis, Github CI runs will fetch more recent package versions and keep the configurations up-to-date.

Browsing Configurations Locally

While the webpage is convenient, you can also directly clone the gh-pages branch of this repository to explore locally:

git clone https://github.com/oracle/kconfigs -b gh-pages
cd kconfigs
grep -r IKCONFIG_PROC out/

How to Run

To run kconfigs locally, you'll need:

• Python 3.11 or later (with pip and virtualenv). Python 3.12 is the official verison in use, but other recent versions work.
• Common CLI compression tools (gzip, bzip2, xz, zstd, tar)
• Linux packaging tools (gpg, rpm, cpio, dpk)
• The make command

If you'd like to do development, then you should also install pipenv, and Python 3.12 which will ensure you use the exact version of Python and all dependencies, which get used in the Github CI system.

The following setup instructions apply to Oracle Linux 9. First, install runtime dependencies (most should already be installed, but they are listed for completeness).

dnf install -y python3.12{,-devel,-venv,-pip} \
               gzip bzip2 xz zstd tar \
               rpm cpio dpkg \
               make

To setup the runtime Python environment:

git clone https://github.com/oracle/kconfigs
cd kconfigs
make venv

# Or if you would like to use pipenv to setup all development dependencies:
make dev

To run the extraction routine:

make run

Configurations will appear in the out directory.

Documentation

You should be able to find everything you need by browsing to our web page which displays the latest kernel configuration information.

Examples

See "How to Run".

If you have any questions or concerns, please open a Github issue and we will try to help you out.

Contributing

This project welcomes contributions from the community. Before submitting a pull request, please review our contribution guide.

For development, you should use Python 3.12 and use pipenv to manage dependencies.

Security

The kconfigs project tries to verify all GPG and checksum metadata for the sources it uses. Here's an overview of what we check:

• RPM-based distributions:
  • A GPG key is required for all RPM-based distributions.
  • repomd.xml: GPG signature required & checked. We do have an exception for some unsigned databases that are served via HTTPS from an allowlist of trusted hosts.
  • Sqlite database: checksum required & checked.
  • RPM package: checksum required & checked, RPM's built-in GPG signature is also required and checked.
• Debian-based distributions:
  • A GPG key is required for all Debian-based distributions.
  • Release file: GPG signature required & checked.
  • Packages file: checksum required & checked.
• Pacman-based distributions:
  • The database file is not signed and cannot be verified.
  • The individual packages are GPG signed, which we verify.
• Upstream kernel configurations:
  • We verify that stable kernel releases have a valid signature from Greg KH.
  • The mainline source distribution is unsigned and cannot be verified.
• Android configurations:
  • We rely on HTTPS connections to source.android.com to ensure the integrity of the data. There are no GPG signatures or checksums provided.
