Mac policy module data

struct mac_module_data_element {
   unsigned int key_size;
   unsigned int value_size;
   unsigned int value_type;
   char *key;
   char *value;

This structure specifies module data that is passed in to the TrustedBSD MAC policy module by the kernel module loader. The data is made of up key/value pairs where the key is always a string and the value is a string, binary data or array. An array may be a list of values (actually a similar set of key/value pairs, but in this case the keys are always null), and may also consist of a set of dictionaries, which in turn are made up of a list of key/value pairs.

Module data may be specified in the MAC policy module's Info.plist file as part of the OSModuleData dictionary.
