On demand, we teach this course completely in in English. Contents In this course, we will discuss selected topics from the area of protection and priviledge isolation in the context of operating systems. Thereby, these topics are developed as an extension of the OOStuBS, as developed in the course Betriebssystembau 1. Starting from a single-processor operating system, privilege isolation, spatial isolation and advanced virtual-memory techniques are explored and implemented. - Privilege isolation
- Use of x86 protection rings to separate user mode and system mode
- System entry through trap-based system calls
- Spatial isolation
- Management of free physical memory
- Virtual address space creation and management
- Execution of processes in their own address space
- Loading of programs; creation of processes
- Advanced address space methods
- Message dispatch without copying
- Copy on Write
- Implementation of
fork(2) Lab assignments are project oriented: The exercises are divided into three parts, which are to be worked on by groups consisting of 2 students. Besides the practical work, there are six lecture-like sessions, where the underlying theory and the concrete technical background for x86 is taught.
