+--------------------------------------------------------------------- +这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值，你也应该把这个魔术值添加到这个文件，因为我们最好把用于各种结构的魔术值统一起来。 + +使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击，或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码，例如，经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。 + +使用魔术值的方法是在结构的开始处声明的，如下： + +struct tty_ldisc { + int magic; + ... +}; + +当你以后给内核添加增强功能的时候，请遵守这条规则！这样就会节省数不清的调试时间，特别是一些古怪的情况，例如，数组超出范围并且重新写了超出部分。遵守这个规则，这些情况可以被快速地，安全地避免。 + + Theodore Ts'o + 31 Mar 94 + +给当前的Linux 2.1.55添加魔术表。 + + Michael Chastain +
