xdp-project-bpf-examples/CONTRIBUTING

This repository exists to serve as an example of well-written code that uses BPF
so that others can learn best practices. Examples range from small snippets
demonstrating a single feature, to slightly larger functional applications.

If you have a code example that you think others would benefit from, you are
very welcome to open a pull request adding your example to this repository. When
doing so, please bear in mind the following guidelines:

- Code should be written following the Linux kernel style guide for C code.
  There's a .clang-format file in the kernel source tree you can use to aid
  formatting.

- The code example should generally use the infrastructure in this repository
  for building. This includes the Makefile and header files in include/. If your
  example requires changes to this infrastructure that is OK; just include those
  as separate commits in the beginning of your PR.

- Make sure to split out your changes into separate commits that can be reviewed
  independently, with a well-written commit message for each describing your
  change at a high level. The kernel guide to submitting patches may be helpful
  here, specifically the sections on "Describe your changes" and "Separate your
  changes": https://docs.kernel.org/process/submitting-patches.html

- Code contributions should generally be licensed as GPLv2, or optionally
  dual-licensed GPLv2/BSD. Source files should have SPDX headers indicating
  their license, and your commits should include a Signed-off-by header
  serving as your Developer's Certificate of Origin (see
  https://docs.kernel.org/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin)

- Make sure to include your code directory in the top-level Makefile, and add a
  README.org file inside the directory describing what your example does.
