问题描述

为了检索正在运行的程序的文件权限,我需要在当前正在运行的程序上执行kstat.然后我需要加载ELF图像的绝对路径.

In order to retrieve file permissions of the running program, I need to do a kstat on the program currently running. Then I need to get the absolute path of the ELF image loaded.

有可能吗? current->comm仅记录不带路径的程序名称.

Is that possible? current->comm only records the program name without path.

或者还有其他方法可以做到吗?

Or what other ways to do it?

推荐答案

您可以readlink(2)带有/proc/self/exe的路径,在您的情况下,这将是指向ELF的链接.使用readlink(1)的元示例:

You can readlink(2) with the path to /proc/self/exe, which in your case would be a link to the ELF. Metaexample using readlink(1):

$ readlink /proc/self/exe
/bin/readlink

据我所知,仅适用于Linux.

Linux-only as far as I know.
