IO80211Controller hack #12
Description
These days I am trying to find ways to fake an 80211Interface so the native client can communicate with our driver, and we don't even to write another user client. But up to now, there is no further progress in this way. I have write an interface, set the interface sub type to 80211interface, and I know how the IOCTL command dispatch, but I don't know how does the system recognize IO80211Family is load, and the wifi panel show. Do you know something about this?
I don’t know if creating an IO80211Interface would work. It seems that the controller itself overrides several base functions (i.e: newUserClient, see: hatf0/Black80211-Catalina)
The way I was envisioning it was to build two drivers- the one facing the 80211 stack, and just an IOService or something facing the physical layer, so we can easily build up the driver’s functions without having to restart every time due to Apple’s WiFi implementation always retaining the card regardless of terminate() being called.
