When more than one security module is exporting data to audit and networking sub-systems a single 32 bit integer is no longer sufficient to represent the data. Add a structure to be used instead. The lsm_prop structure definition is intended to keep the LSM specific information private to the individual security modules. The module specific information is included in a new set of header files under include/lsm. Each security module is allowed to define the information included for its use in the lsm_prop. SELinux includes a u32 secid. Smack includes a pointer into its global label list. The conditional compilation based on feature inclusion is contained in the include/lsm files.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
