System, method and apparatus for fine granularity access protection
Abstract:
A system, apparatus and method for accessing an electronic storage medium, such as a memory location storing a page table, or range table. A virtual address of the electronic storage medium is identified that corresponds to designated portions, such as a range of addresses of the electronic storage medium. The virtual address is translated to a corresponding physical address and one or more commands are identified as being excluded from execution in the designated portions of the electronic storage medium. This may be accomplished by using a routine such as mprotect( ). A fault indication, or decoration, is provided to meta-data associated with the physical address, which is associated with the designated portions of the electronic storage medium when excluded commands are provided to the physical address. A mechanism, such as hardware, is actuated when the fault is generated.
