那个offset是文件的偏移,也是0x1000的整数倍。 The contents of a file mapping (as opposed to an anonymous mapping; seeMAP_ANONYMOUSbelow), are initialized using length bytes starting at offset offset in the file (or other object) referred to by the file descriptor fd. offset must be a multiple...

每一种系统支持的可执行文件都对应一个linux_binfmt对象,统一注册在一个链表中,通过register_binfmt和unregister_binfmt函数编辑链表。在执行可执行程序时,内核通过list_for_each_enrty遍历链表中注册的linux_binfmt对象,使用正确的加载方式进行加载。 一、源码版本 ...
