Sounds silly but how do I get access to the file descriptor?
Also If I make the user create a session for an operation similar to this
paper
http://www.usenix.org/event/usenix03/tech/full_papers/keromytis/keromytis_html/node8.html#SECTION00042000000000000000,
should I remove the read, write operations and do all operations using ioctl
commands i.e. reading the user buffer etc?
