Doing packet > injection on monitor interfaces instead is safer in that regard. But if you want to do injection over monitor interfaces we'll need to have the stupid mgmt interface hack around forever for the userspace MLME so it can receive only management traffic (even the non-promisc monitor iface we should have gets *far* too much traffic for a userspace MLME) Besides, to userspace, this is almost identical. In both cases it opens a socket, binds to something (either raw socket bound to netdev or netlink socket bound to nl80211) and then stuffs frames into that socket with some fixed header format (for most apps anyway) johannes
