An “Oops” is what the kernel throws at us when it finds something faulty, or an exception, in the kernel code. It’s somewhat like the segfaults of user-space. An Oops dumps its message on the console; it contains the processor status and the CPU regi…

Understanding a kernel panic and doing the forensics to trace the bug is considered a hacker's job. This is a complex task that requires sound knowledge of both the architecture you are working on, and the internals of the Linux kernel. Depending on…

P30, preemptive  kernel .kernel threading 和Multithreaded application support没太好理解,我想如果设计个多线程的程序来运行运行,恐怕就好理解了.搞清楚了! 在source code里面, arch和include是和硬件相关的代码,arch下面是architecture-specific的文件, include下面放的是内核的所有头文件,其中带有asm前缀的子目录里面是particular architecture的头文件…

There are three ways to pass options to the kernel and thus control its behavior: When building the kernel. Most of this book discusses these options. When starting the kernel. Usually, parameters are passed to the kernel when it is invoked from a bo…

我把我学习kernel编程的过程介绍给大家,希望大家有个参考. 学习kernel编程需要阅读大量的kernel方面的书籍,在此我列举一下我读过的kernel书籍(按时间先后顺序),并给一些建议. 1. LDDv3(Linux Device Driver Program)linux设备驱动编程 2. Linux内核情景分析,上,下 3. ULK(Understanding Linux Kernel)v2, v3 4. Linux 0.11内核完全注释 5. ULN(Understanding Li…

kernel module version check bypass . 举例说明 . 内核是怎么实现的 . 怎样去突破 . 总结 . 举例说明 Linux内核版本很多,升级很快,2个小内核版本中内核函数的定义可能都不一样,为了确保不一致的驱动程序导致kernel oops, 开发者加入了模块验证机制.它在加载内核模块的时候对模块进行校验, 如果模块与主机的一些环境不一致,就会加载不成功. 看下面一个例子,它简单的输出当期系统中的模块列表: ---------------------------…
