yzh07137:你好,我看了你的这篇关于linux劫持open调用的文章[url]http://bbs.chinaunix.net/thread-1946913-1-1.html[/url](有点久远了)
我在ubuntu12.04.5(内核是3.13.0.20-32-generic)上试验了,结果编译报错了,那个Makefile不能成功执行,提示下面这个错误:
error:'struct pt_regs' has no member named 'ebx';
error:'struct pt_regs' has no member named 'ecx';
error:'struct pt_regs' has no member named 'edx';
error:'TIF_IRET' undeclared(first used in this function);
这是error,还有一些警告,请问是什么原因啊,是因为内核版本的问题吗?
估计应该是版本问题。Linux kernel code 你可以直接看啊,查一下爱对数据局结构是否还有相关成员。
