Abstract: An example processing system may comprise: a lower stack bound register configured to store a first memory address, the first memory address identifying a lower bound of a memory addressable via a stack segment; an upper stack bound register configured to store a second memory address, the second memory address identifying an upper bound of the memory addressable via the stack segment; and a stack bounds checking logic configured to detect unauthorized stack pivoting, by comparing a memory address being accessed via the stack segment with at least one of the first memory address and the second memory address.

Abstract translation: 示例处理系统可以包括：下堆叠绑定寄存器，被配置为存储第一存储器地址，第一存储器地址标识经由堆栈段可寻址的存储器的下限; 上堆叠绑定寄存器，其被配置为存储第二存储器地址，所述第二存储器地址通过所述堆栈段识别所述存储器可寻址的上限; 并且通过将经由所述堆栈段访问的存储器地址与所述第一存储器地址和所述第二存储器地址中的至少一个进行比较来配置用于检测未授权堆栈枢转的堆栈边界检查逻辑。

Abstract: In one embodiment of the present invention, a method includes switching between a first address space and a second address space, determining if the second address space exists in a list of address spaces; and maintaining entries of the first address space in a translation buffer after the switching. In such manner, overhead associated with such a context switch may be reduced.
