SELinux Common Intermediate Language (CIL) Compiler
INTRODUCTION
The SELinux CIL Compiler is a compiler that converts the CIL language as
described on the CIL design wiki into a kernel binary policy file.
Please see the CIL Design Wiki at:
http://github.com/SELinuxProject/cil/wiki/
for more information about the goals and features on the CIL language.
DEPENDENCIES
gcc >= 4.5.1
libsepol-static >= 2.1.4
lcov >= 1.9
flex >= 2.5.35
BUILD STEPS
Open a terminal client and execute the following command to download the source code:
git clone https://github.com/SELinuxProject/cil.git
Change directory into the "cil" directory.
Run "make" with one of the following targets:
make
Build the CIL compiler (secilc)
make unit
Build the unit_test application to run unit tests
make coverage
Build the unit test binary and create coverage reports
make clean
Remove temporary build files
make bare
Remove temporary build files and compile binaries
USAGE
Execute 'secilc' with any number of CIL files as arguments. A binary policy and
file_contexts file will be created.
Use the '--help' option for more details.
DOCUMENTATION
There is a Docbook CIL Reference Guide in the docs directory, to build
this in HTML and PDF format change to the docs directory and run:
make html pdf
There is also an secilc man page that can be built with:
make man
The documents will be located in the docs/html, docs/pdf and docs/man8
directories.
To build the html and manpage the xmlto package is required.
To build the pdf document the xmlto and dblatex packages are required.
KNOWN ISSUES
- Blocks inside of macros causes undefined behavior
- Policy must be well formed. For example, invalid usage of
sensitivities/categories/levels may create an unloaded binary
- Recursive limits are not handled
