Coccinelle
==========
Coccinelle is a tool for pattern matching and text transformation that has
many uses in kernel development, including the application of complex,
tree-wide patches and detection of problematic programming patterns.
Getting Coccinelle
------------------
The semantic patches included in the kernel use features and options
which are provided by Coccinelle version 1.0.0-rc11 and above.
Using earlier versions will fail as the option names used by
the Coccinelle files and coccicheck have been updated.
Coccinelle is available through the package manager
of many distributions, e.g. :
- Debian
- Fedora
- Ubuntu
- OpenSUSE
- Arch Linux
- Gentoo
- NetBSD
- FreeBSD
Some distribution packages are obsolete and it is recommended
to use the latest version released from the Coccinelle homepage at
https://coccinelle.gitlabpages.inria.fr/website
Or from Github at:
https://github.com/coccinelle/coccinelle
Once you have it, run the following commands::
./autogen
./configure
make
as a regular user, and install it with::
sudo make install
More detailed installation instructions to build from source can be
found at:

Supplemental documentation
--------------------------
For supplemental documentation refer to the wiki:
https://bottest.wiki.kernel.org/coccicheck.html
The wiki documentation always refers to the linux-next version of the script.

Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
