Linux Kernel Learning notes collation.UnixUnix has a history of 40, but computer scientists still think it is the largest and best system in the existing operating system, it has become a legendary existence, the test of time is still a reputation.In 1973, after the UNIX system was rewritten in C, a large number of Unix-derived versions began to emerge, and many companies migrated UNIX to new models, and de
Linux Kernel updates are getting faster and faster. Due to the popularity of Linux, everyone is paying attention to it and there are more and more security risks. Supports Intel, Alpha, PPC, iSCSI, IA-64, ARM, MIPS, Amiga, Atari, IBM s/390, and 32-bit large file systems. On the Intel Platform, the maximum physical memory support is 64 GB. Enhanced support for I
Then after the Linux kernel 2.6, can not directly export sys_call_table address, we want to get the address of the system call table, so as to achieve the interception of system calls.First put on my implementation of the good code, and then to explain it.Modu.c#include #include#include#include#include#include#includestring.h>#include#include#include#includeModule_license ("Dual BSD/GPL"); #define_debug#ifd
