我们知道,在 OS(operating system)中有一个 kernel mode, user mode 的概念,其用处在于限定 instruction 的执行权限。处于 user mode 的 instruction,不可以直接执行访问 hardware 等敏感操作;而处于kernel mode的 instruction 则可以。 如果不深究细节,似乎 user/k
The MODEB kernel provides dynamic process management, dynamic priorities, powerful synchronization operations, support of interrupt programming, and timer functions. The experience with Modula-2 pointed out, that the use of a high level programming language helps a programmer to write simple, reliable,...
Kernel Mode Rootkits The operating system kernel represents the highest level of privilege in a modern general purpose computer. The kernel arbitrates access to protected hardware and controls how limited resources such as running time on the CPU and physical memory pages are used by processes on ...
