Abstract:
Accessing privileged objects in a server environment. A privileged object is associated with an application comprising at least one process resource and a corresponding semi-privileged instruction. The association is filed in an entity of an operating system kernel. A central processing unit (CPU) performs an authorization check if the semi-privileged instruction is issued and attempts to access the privileged object. The CPU executes the semi-privileged instruction and grants access to the privileged object if the operating system kernel has issued the semi-privileged instruction; or accesses the entity if a process resource of the application has issued the semi-privileged instruction to determine authorization of the process resource to access the privileged object. Upon positive authorization the CPU executes the semi-privileged instruction and grants access to the privileged object, and upon authorization failure denies execution of the semi-privileged instruction and performs a corresponding authorization check failure handling.
