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 fill all the needed fields of "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 results of this algorithm, I need to send an extra message to the station. This is why I cannot simply use a raw socket in the user space, for example. Any idea how to achieve my goal? Or any point to a "guide" that help me to understand what I really need to do? The kernel version in use is the "3.2.0-4-686-pae".
