I am trying to figure out how the hostapd work. Untill now I know that the driver passes all the packets to the userspace (i.e hostapd) using PF_PACKET socket. The netif_rx function called in prism2_rx_80211(defined in hostap_80211_rx.c)may relay the packet to user space daemon. Is it right?
Then hostapd deals with IEEE 802.11 management and data frames.It also takes care of the IEEE 802.1x authentication.
But I m not clear where the virtual ports are assigned to each station. Is there any number assigned to port for a station?
Who decides in which state the port is(in authorized or unauthorized state). What actions are taken by the driver when the 802.1x authentication is successful?
Please focus a light on this issue.......
Thanks in advance
