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/kernel mode 是非常显然的模式,不就类似于调用某个 H...
All code that runs in kernel mode shares a single virtual address space. This means that a kernel-mode driver is not isolated from other drivers and the operating system itself. If a kernel-mode driver accidentally writes to the wrong virtual address, data that belongs to the operating system...
内核栈用于保存各个寄存器值:CS,DS,SS等. os层面的线程进程切换,都是在kernel mode下操作的。每个process都有自己unique的内核栈(因为每个process对应一个task_struct,kernel stack is member of the struct). process context switch: 从user mode 到kernel mode, 内核stack用于保存user mode的寄存器值,用于下次返回...
另外,6.0上废除了Full Kernel Mode的不合理设计,将Kernel Mode和User Mode进行了细分。由此带来了本文中要讨论的问题,就是如何在User Mode下操作Kernel Mode下的内存空间。 大家一定想到了,简单的在User Mode下访问Kernel Mode下才有权限访问的内存肯定是行不通,可以间接的通过Kernel下的Driver或者其它与Kernel中的代...
So there’s this DLL in Windows calledkernel32.dll. From its name, you might expect it to be the code that controls 32-bit kernel mode. But in reality, it runs in user mode. Why is the “kernel” running in user mode? Set the time machine to 1985. ...

The OS is usually listed on the first line. Find the kernel line. In Azure, it starts with linux or linux16. Press Ctrl+E to go to the end of the line. At the end of the line, add systemd.unit=rescue.target. This action boots you into single-user mode. If you want to use ...
