ImageDecoder: Add a new service for out-of-process image decoding :^) The new ImageDecoder service (available for members of "image" via /tmp/portal/image) allows you to decode images in a separate process. This will allow programs to confidently load untrusted images, since the bulk of the security concerns are sandboxed to a separate process. The only API right now is a synchronous IPC DecodeImage() call that takes a shbuf with encoded image data and returns a shared buffer and metadata for the decoded image. It also comes with a very simple library for interfacing with the ImageDecoder service: LibImageDecoderClient. The name is a bit of a mouthful but I guess we can rename it later if we think of something nicer to call it. There's obviously a bit of overhead to spawning a separate process for every image decode, so this is mostly only appropriate for untrusted images (e.g stuff downloaded from the web) and not necessary for trusted local images (e.g stuff in /res) 2020-06-22 21:35:22 +02:00			`endpoint ImageDecoderServer = 7001`
