Abstract
System, method and computer program product for supporting a plurality of Access Control List types for a file system in an operating system in a data processing system. An Access Control List supporting system for managing access to a file system in a data processing system has at least one file system in an operating system of the data processing system, and an Access Control List management framework in the operating system and external to the at least one file system for managing access to the at least one file system. The Access Control List supporting system of the invention removes ACL management and access check-related functions from the at least one file system to an external Access Control List management framework, thus enabling an operating system to support a plurality of Access Control List types using the same Access Control List management framework and enabling new Access Control List types to be added to the operating system dynamically while the operating system is running.
