shellcode动态调试 记住编译的时候一定要加-fno-stack-protector -z execstack gcc参数加上 -z execstack, 归根到底就是要让你这段shellcode所放的内存有执行的权限
内核和应用程序的编译是不一样的，编译应用的时候会调用一些你的编译器工具链里的libc库的，但是编译内核的时候是不能call这些lib的，所以不能按着编译应用的思想去编译内核。你这个选项根本对内核无用。
-fno-stack-protector参数用来disable Stack-smashing protection ,高版本gcc默认用-fstack-protector参数进行编译。 问题6: 之后又出现如图2.6所示的问题。 图2.6 这个问题简单,就是build.c程序找不到MAJOR和MINOR的实现体,那么就打开build.c将这两个宏的实现加入便可,如图2.7所示。 图2.7 至此,make已经可以...
