在挂载点上执行时命令被杀死 [英] Commands are getting killed when executing on mount point

问题描述

我创建了一个文件系统，当我将它挂载到任何目录并执行该挂载点上的任何命令时（ls / mkdir等）我输出为KILLED。

那是什么意思是，哪个过程被杀死了，为什么。这个问题的解决方案是什么。



提前致谢:)



我是什么尝试过：



将内核模块插入insmod example.ko

挂载为mount -o loop - 示例图像mnt

I have created a file sytem, when I mount it on any directory and execute any command on that mount point(ls/mkdir etc) I am getting the output as KILLED.
What does that mean, which process is getting killed and why. What is the solution of this problem.

Thanks in advance :)

What I have tried:

Inserted the kernel module as "insmod example.ko"
mounted as "mount -o loop -t example image mnt"

推荐答案

消息由内核发出。我假设你自编的内核模块以某种方式失败。



检查内核日志文件中是否有条目（ / var / log / kern .log 包含大多数发行版）。如果是这样，它可能会提供更多信息。



常见解决方案：调试。



因为调试内核模块相当复杂，您可以先使用 printk（）来记录模块的活动。

The message is issued by the kernel. I assume that your self written kernel module fails in some way.

Check if there is an entry in the kernel log file (/var/log/kern.log with most distributions). If so, it might provide more information.

The common solution: Debugging.

Because debugging kernel modules is rather complicated you can start by using printk() to log the activities of your module.
