Subject: opening a file inside the kernel module

Hi all,
I am working in linux, i would like to know abt whether can I open a file
inside the kernel module without using any application. If so how how the
files_struct will be maintained. Does a kernel module has this struct?

Waiting for any suggestion from the list.

Thanks in advance,
rakesh

Don't do this. It's incompatible with namespaces.

Instead, figure out some way to pass the file contents to the kernel module.

Hi,
Thnx.

I want to implement socket from the module. I won't be having any user
process running to handle the descriptors coming from socket. Could you pl
tell me how to handle the socket descriptor from the kernel module.

Thanks,
rakesh

Check out fs/smbfs/sock.c.
