-Modules should be placed in refpolicy/policy/LAYER, where LAYER is the name of the appropriate layer. The current layers can be seen in the interface documentation. Let's create a new module in the services layer called myapp. This is done by creating three files: myapp.te, mayapp.fc, and myapp.if, all in directory refpolicy/policy/services. The file myapp.te file will contain all of the policy private to this module, including any types or attributes. The file myapp.fc file will containt the file context labeling statement for this module. Finally, the file myapp.if will contain the inferfaces for this module (interfaces will be explained below). +Modules should be placed in refpolicy/policy/LAYER, where LAYER is the name of the appropriate layer.

-This creates all fo the types needed for this module, including a type for the process, executables, log files, and temporary files. The first thing to notice is that there are no attributes applied to any of these types. In refpolicy all types and attributes can only be referred to in the module that declares them. This means that it is not possible, for example, to directly refer to the domain attribute. Instead, macros in other modules are used to declare that a type will be used for a certain purpose. These macros will likely use attributes (but not necessarily), but it allows the module that declared the attribute to strictly control how it can be used. In this example interfaces are used to transform the types into a domain, entry file, log file, and temporary file. +This creates all of the types needed for this module, including a type for the process, executables, log files, and temporary files.

Let's expand this example further by allowing some access for these types. My application needs access between it's own types and access to read random numbers. The access between private types is written exactly the same way current policy rules are written, i.e.: diff --git a/www/html/index.html b/www/html/index.html index 6f667dda..32949674 100644 --- a/www/html/index.html +++ b/www/html/index.html @@ -15,7 +15,7 @@ Refpolicy is under active development, with support and full time development st
