| 摘 要： | 操作系统通常仅提供超级用户进程直接访问raw磁盘的方法。为使非超级用户进程也能够利用SAN文件系统访问raw磁盘,SAN文件系统必须对非超级用户进程进行授权。该文提出了一种基于访问权力传递的raw磁盘访问授权方法,实现了非超级用户进程对SAN文件系统的透明访问,并结合一个实际的SAN文件系统,给出了该方法的具体实现例子。

| Abstract: | In general,operating systems only provide the method of accessing raw disks for root users' processes.In order to support non-root users' processes running on SAN file system,right of access to raw disks must be granted to such processes.We present a method of granting right of access to raw disks to non -super users' processes in a transparent way,based on passing of access rights.An example about how to implement this method is given by a factual SAN file system. |
