SELinux uses CAP_MAC_ADMIN to control the ability to get or set a raw, uninterpreted security context unknown to the currently loaded security policy. When performing these checks, we only want to perform a base capabilities check and a SELinux permission check. If any other modules that implement a capable hook are stacked with SELinux, we do not want to require them to also have to authorize CAP_MAC_ADMIN, since it may have different implications for their security model. Rework the CAP_MAC_ADMIN checks within SELinux to only invoke the capabilities module and the SELinux permission checking.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
