Interesting. I feel like there are some strange exploits that could come from this though. Archive: https://archive.today/S90ui From the post: >>An exciting Intel innovation expected to be added for the upcoming Linux 7.2 kernel is introducing the new USB4STREAM protocol for USB4/Thunderbolt as a "super simple" way to "basically just transfer raw packets from one host to another". This can be useful for quickly backing up a system from one host to another, sharing of web cameras or other peripherals across systems, or other environments where not having networking or wanting to avoid the traditional Linux networking stack. Intel Thunderbolt maintainer Mika Westerberg has been working on the USB4STREAM support with the thunderbolt_stream driver that looks like it's all buttoned up in time for next month's Linux 7.2 merge window. The thunderbolt_stream driver exposes /dev/tbstreamX devices on each host of a directly-connected USB4/Thunderbolt cable. From there data can be transferred using regular file-system operations, e.g. you can dd or cat from one system to another or similar commands.
