want to read a file from kernel module
 

Hi,

I am novice to Linux. I have one requirement where the kernel module has to read one file (configuration data). The file system is mounted using NFS. So i have to read one file from one of the locations usin NFS & copy to local kernal buffer & process the data. Could you please help me out on this.
Thanks in advance.

Hello there and welcome to LQ, hope you like it here.

...and to LQ. You posted your thread in the Linux User Groups (LUG) forum, which is wrong.

You can't make the kernel (or LKM) "read" a file: that's not how it works. If that's in the design of what you do then your thinking is wrong and your design dangerous and flawed. Do not proceed down that path: read the LKML (Linux Kernel mailinglist)! If you want to interface use /proc sysctl or any existing API: look for instance at how userland binaries like Iptables interface with the Netfilter framework.

Thanks for the reply.
But i have one requirement in my project where i have to get the configuration data for a device from some location (usng NFS) and then write on to the Hardware device. This has to be handled by Kernel module. Could any body give me some suggestions on this??

Thanks in advance
