Modify cil_gen_node() to check to see if the cil_db supports multiple declarations, and if so, to check whether or not the repeated symbol is eligible to share the existing, already-stored datum. The only types considered so far are CIL_TYPE and CIL_TYPEATTRIBUTE, both of which intall empty datums during AST building, so they automatically return true. Test: Build policy with multilpe type and attribute declarations, and without. Policies are binary-identical.

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 >= 2.5 BUILD STEPS Run "make" with one of the following targets: make Build the CIL compiler (secilc). make test Pass a sample policy to test with the compiler. make install Install the secilc compiler and man page to disk. make clean Remove temporary build files. make man Build the secilc man page. 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 github markdown CIL Reference Guide in the docs directory. To view the table of contents, see README.md in the docs directory. To convert the github markdown content to HTML and PDF, change to the docs directory and run: make The documents will be located in the docs/html and docs/pdf directories. To build the html and pdf, the pandoc package is 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
