using sys_chmod

greplinux · 05-14-2012, 03:41 AM

Hi,

I am trying to use sys_chmod in my kernel module to change the permission of a file. But i am getting sys_chmod undefined error, while trying to compile.

Googled for this, but not able to get this resolved. Are there any steps we should follow inorder to use sys_chmod?

My linux kernel version is 2.6.24.

Thanks,

You provides less information. You need to be more specific. What command you tried to compile, which OS you're using, etc.?

Its a Linux kernel loadable module. I think, i have already mentioned the version details. Please let me know what other information you needed.

Thanks,

Hi Arya,

I am trying to use sys_chmod function call in my Linux kernel module. While compiling that source, I am getting 'sys_chmod' undefined symbol error. I would like to know the method to follow to achieve this. Please let me know if you need any more info.

Thanks,

you know posting an error message alone is not a good idea. You would better post also your files or links (if they available on the net), the commands and the whole output.
I think this time you missed an #include somewhere, but I'm not really sure, there can be other problem as well.

In simple terms, post all the commands you tried and their outputs here.
