Coccinelle

Coccinelle is a tool utilized in Linux kernel development for pattern matching and text transformation, enabling the application of complex patches and the detection of programming issues. It requires version 1.0.0-rc11 or higher for compatibility with the kernel's semantic patches. Coccinelle can be installed via package managers on various distributions or built from source. The tool operates in several modes, including patch, report, context, and org, with the default being report. Users can specify which files or directories to process and can run checks in parallel. Debugging options are available to capture error messages and profiling information. Coccinelle supports configuration through a .cocciconfig file, allowing users to set default options. Additionally, it can utilize external tools for indexing code to enhance performance. Developers can propose new semantic patches, which should be organized in the scripts/coccinelle/ directory. The tool is essential for maintaining code quality in the Linux kernel by providing automated checks and facilitating code transformations.
