opening, reading, writing to file from kernel

I need to change the data field in select outgoing TCP packets with information from a data file in user space. I think the easiest way to do this would be to replace the pointer to skb->data with a pointer to the applicable portion of my data file. But, I'm not clear on how to do this.

I'd prefer just to do a sys_open() or some other file open command to gain access to my data file.

Any ideas? I apologize, but, I am by no means a kernel level programmer. I'm just trying to get the kernel to do this one little thing.

Thanks in advance for any specific examples
