With two platform integrations: - macOS: where we use Apple's tunnel, by talking to remotepairingd and creating an assertion to ensure the tunnel is up and stays up for as long as we need it. The challenging part here was figuring out the device-side RemoteServiceDiscovery (RSD) port inside the tunnel, as it appears no API exposes it. Our solution is to ask the kernel for a list of TCP sockets, and picking out the ones where the foreign address is the device-side IPv6 address inside the tunnel, **and** where the process that created the socket is remoted. This seems to consistenly result in us finding a single socket, connected to the RSD port, but we try all of them in case this behavior ends up changing. - Linux: where we open our own tunnel, assuming the iDevice has been mode-switched (e.g. by usbmuxd), and the Linux CDC NCM driver has been patched something along the lines of: https://lore.kernel.org/all/[email protected]/T/ We don't yet have a platform integration for Windows, as Apple's software doesn't currently set up a tunnel. The official driver also appears to keep the USB device busy, meaning we can't easily trigger a mode-switch. This is an area that needs more research. Another area that needs future improvement is that we only support cabled connectivity on macOS. This should be easy to improve on once we have updated frida-server and frida-gadget so they listen on tunnel interfaces whenever they appear. Kudos to @doronz88 for figuring out most of the protocol bits that we needed. Co-authored-by: Håvard Sørbø <[email protected]>
