2022-09-29landlock: Fix documentation styleMickaël Salaün1-2/+2
It seems that all code should use double backquotes, which is also used to convert "%" defines. Let's use an homogeneous style and remove all use of simple backquotes (which should only be used for emphasis).

2022-09-29landlock: Slightly improve documentation and fix spellingMickaël Salaün1-2/+2
Now that we have more than one ABI version, make limitation explanation more consistent by replacing "ABI 1" with "ABI < 2". This also indicates which ABIs support such past limitation. Improve documentation consistency by not using contractions. Fix spelling in fs.c .

2021-06-17docs: security: landlock.rst: avoid using ReST :doc:`foo` markupMauro Carvalho Chehab1-1/+2
The :doc:`foo` tag is auto-generated via automarkup.py. So, use the filename at the sources, instead of :doc:`foo`.

2021-04-22landlock: Add user and kernel documentationMickaël Salaün1-0/+85
Add a first document describing userspace API: how to define and enforce a Landlock security policy. This is explained with a simple example. The Landlock system calls are described with their expected behavior and current limitations. Another document is dedicated to kernel developers, describing guiding principles and some important kernel structures. This documentation can be built with the Sphinx framework.
