Hi all,
I am trying to send a custom ethernet packet through a kernel module (mac80211) and I am facing some problems to understand what I really need to do.
Until now, I realize that I need to create an sk_buff and send it via dev_queue_xmit function. Am I right?
My problem is how to properly create and configure the sk_buff with my data (I only need to pass a number).
In order to give you some context, I am working on a research in IEEE 802.11 and I am developing a mechanism to send the packets in an energy efficient way. Therefore, I need to employ a specific algorithm before adding the Traffic Indication Map (TIM) into the Beacon frame and, depending on the result of this algorithm, I need to send an extra message to the station. This is why I cannot use just a raw socket in the user space.
Any idea how to achieve this goal? Or any point to a "guide" that help me to understand what I really need to do?
The used kernel version is "3.2.0-4-686-pae".
Best regards,
