2020-06-28libcamera: ipu3: Always import buffers for ImgU sinksNiklas Söderlund
When the IPU3 pipeline was first developed sinks of the ImgU that where not active still needed to have buffers allocated to allow streaming to start. This is no longer true, it's enough that the sinks have imported buffers to allow streaming to start. As we already need to import buffers for stream that are active we can align the two cases and always import buffers. With this there is no longer a reason to store the allocated FrameBuffers to keep them alive and the vector tracking them can be removed.

Decouple the number of buffers to allocate for the ImgU from the number of buffers allocated for the CIO2. Instead of blindly following the CIO2 pick the maximum number of buffers requested for any stream facing applications. This is potentially wasteful, as each stream could allocate just as many buffers as requested by the application instead of the maximum from the set. But this is not more wasteful than what is already used by the pipeline and should be fixed on top after the decoupling of the two processing units.

2020-06-25v4l2: v4l2_camera: Clear pending requests on freeBuffers and streamOffPaul Elder
V4L2 allows buffer queueing before streamon while libcamera does not. The compatibility layer thus saves these buffers in a pending queue until streamon, and then automatically queues them. However, this pending queue is not cleared when the buffers are freed, so the following sequence of actions will cause a use-after-free: 1. queue buffers 2. free buffers - buffers from 1. stay in pending queue but have been freed 3. queue buffers 4. streamon - buffers from 1. are enqueued, then the buffers from 3. are enqueued. Use-after-free segfault when libcamera tries to handle the enqueued buffers from 1. Fix this by clearing the pending request queue upon buffers being freed. Also clear the pending request queue on streamOff, for correctness.

2020-06-25v4l2: v4l2_compat: Support multiple openPaul Elder
Previously, since we acquired the libcamera camera upon open(), it was impossible to support multiple open, as any subsequent opens would return error because the camera would already be acquired. To fix this, we first initialize the camera in the first call to V4L2CameraProxy::open(), just to heat up the stream format cache. We then add ownership by a V4L2CameraFile of a V4L2Camera via the V4L2CameraProxy. All vidioc ioctls prior to reqbufs > 0 (except for s_fmt) are able to access the camera without ownership. A call to reqbufs > 0 (and s_fmt) will take ownership, and the ownership will be released at reqbufs = 0. While ownership is assigned, the eventfd that should be signaled (and cleared) by V4L2Camera and V4L2CameraProxy is set to the V4L2CameraFile that has ownership, and is cleared when the ownership is released. In case close() is called without a reqbufs = 0 first, the ownership is also released on close(). We also use the V4L2CameraFile to contain all the information specific to an open instance of the file. This removes the need to keep track of such information within V4L2CameraProxy via multiple maps from int fd to info. Since V4L2 does not expect reqbufs 0 to ever return error, make V4L2CameraProxy::freeBuffers() return void.

The dup function is also modified, in that it is removed from V4L2CameraProxy, and is handled completely in V4L2CompatManager, as a map from file descriptors to V4L2CameraFile instances.

2020-06-25v4l2: v4l2_camera_file: Add V4L2CameraFile to model the opened camera filePaul Elder
With relation to opening files, the kernel has three objects related to files: - inodes, that represent files on disk - file objects, that are allocated at open() time and store all data related to the open file - file descriptors, that are integers that map to a file In the V4L2 compatibility layer, V4L2CameraProxy, which wraps a single libcamera camera via V4L2Camera, is more or less equivalent to the inode. We also already have file descriptors (that are really eventfds) that mirror the file descriptors. Here we create a V4L2CameraFile to model the file objects, to contain information related to the open file, namely if the file has been opened as non-blocking, and the V4L2 priority (to support VIDIOC_G/S_PRIORITY later on). This new class allows us to more cleanly support multiple open later on, since we can move out of V4L2CameraProxy the handling of mapping the fd to the open file information.
