在进行sys_call_table replace hook的时候,我们往往需要借助系统头文件<asm/unistd.h>的__NR_XX宏定义来定位寻址到我们要hook的目标系统调用处理函数,需要注意的是,这个宏定义在32/64bit的Linux上存在着一些差异,我们在编写sys_call_table hook engine的时候需要特别注意这块的兼容性 print_NR.c #include <asm/u...

hardware interrupt) andsynchronous interrupts(akaexception). The former mayarrive anytime, typically IO interrupts, the latter mayonly arrive after the execution of an instruction, for example when the cpu try to divide a number by 0 or a page fault. So that’s the difference between interrupts...

Important note: PRoot can make program to appear under root user id due to faking system call arguments and return values, but it does not provide any way for the real privilege escalation. Programs requiring real root access to modify kernel or hardware state will not work. ...
The kernel provides these and other basic services: interrupt and trap handling, separation between user and system space, system calls, scheduling, timer and clock handling, file descriptor management. Now something about the Windows Kernel:

ASIO vs. MME, WDM, and WASAPI Most audio software will allow you to choose between the ASIO, MME, WDM, or WASAPI driver. The question then becomes which driver format you should use. There are a few things to consider when choosing the primary playback and recording device. Using a Wind...
We show that this is the only difference between the lit-only σ+-game and the σ+-game regarding the reachability problem. More precisely, we have the following theorem whose proof is deferred until Section 2. Theorem 3 Let B≠0̸ and C≠V(G) be configurations on a connected graph ...
