Help related to socket creation in kernel space

[Amit Luniya]

Hello sir,
      I am final year student of comp. engg. from pune
university. My project is hibernation in network
environment. Existing utility of hibernation using
"swsusp.c" does not support ping operation or any
other n/w related services after resume. 
  Tell me whether could we create socket in code of
resume in such a way that we can get image back from
server? As ping is application layer program does not
support operation after resume , so could we do
creation of socket and write kernel level network
program in resume process and can communicate with
server?
 We are working on linux kernel 2.6.14.5 .
Please help us as we are hang over our project.
Have a good day sir.....

IMO, you can deal with low level socket and sk_buff, in kernel-space. I
don't know whether there is other way. If you want to notify the resume
process or do something like connecting to a server after resume, I
think you better write a small module to pass events to userspace (using
kernel-user space linker/connector) then let userspace programs do
whatever they want.

And the last thing, I don't know if network codes is legal in resume
process or not.
