Linux 磁盘管理 Linux 磁盘管理好坏直接关系到整个系统的性能问题。 Linux 磁盘管理常用三个命令为df、du和fdisk。 df(英文全称:disk free):列出文件系统的整体磁盘使用量 du(英文全称:disk used):检查磁盘空间使用量 fdisk:用于磁盘分区 df df命令参数功能:检查文件系统的磁盘空间占用情况。可以利用该命令来获取硬盘...
o /proc Provides system statistics through a browsable directory-and-file interface. Much of the /proc subdirectory structure on Linux is unique, but many other Unix variants have similar features. The /proc directory contains information about currently running processes as well as some kernel param...

How the Linux Kernel Boots(第5章 Linux内核的启动过程) You now know the physical and logical structure of a Linux system, what the kernel is, and how to work with processes. This chapter will teach you how the kernel starts— or boots. In other words, you’ll learn how the kernel ...
session frees that structure. No synchronisation protects the pointer,so the first thread dereferences freed memory – a classicuse‑after‑free that leads to kernel memory corruption and arbitrary codeexecution in kernel context.Affected code path...
