| * media: v4l2-common: Add support for fractional bppNicolas Dufresne2023-06-091-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Fraction bytes-per-pixel exist for some packed format. You will find notably on Rockhip platform that 10bit data is stored fully packed, meaning that there is 1.25 pixels per bytes. This can be represented with the fraction 5/4 and can be used to scale the width into a bytesperline.

* media: dvb-core: Fix use-after-free due to race at dvb_register_device()Hyunwoo Kim2023-05-141-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | dvb_register_device() dynamically allocates fops with kmemdup() to set the fops->owner. And these fops are registered in 'file->f_ops' using replace_fops() in the dvb_device_open() process, and kfree()d in dvb_free_device(). However, it is not common to use dynamically allocated fops instead of 'static const' fops as an argument of replace_fops(), and UAF may occur. These UAFs can occur on any dvb type using dvb_register_device(), such as dvb_dvr, dvb_demux, dvb_frontend, dvb_net, etc. So, instead of kfree() the fops dynamically allocated in dvb_register_device() in dvb_free_device() called during the .disconnect() process, kfree() it collectively in exit_dvbdev() called when the dvbdev.c module is removed.

| | | | | | | | | | | | | | | | | | | | A race condition may occur between the .disconnect function, which is called when the device is disconnected, and the dvb_device_open() function, which is called when the device node is open()ed. This results in several types of UAFs. The root cause of this is that you use the dvb_device_open() function, which does not implement a conditional statement that checks 'dvbnet->exit'. So, add 'remove_mutex` to protect 'dvbnet->exit' and use locked_dvb_net_open() function to check 'dvbnet->exit'.

| | | | | | | | | | | | | | | | | | | If the device node of dvb_frontend is open() and the device is disconnected, many kinds of UAFs may occur when calling close() on the device node. The root cause of this is that wake_up() for dvbdev->wait_queue is implemented in the dvb_frontend_release() function, but wait_event() is not implemented in the dvb_frontend_stop() function. So, implement wait_event() function in dvb_frontend_stop() and add 'remove_mutex' which prevents race condition for 'fe->exit'.

* media: v4l2-subdev: Add new ioctl for client capabilitiesTomi Valkeinen2023-04-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new ioctls to set and get subdev client capabilities. Client in this context means the userspace application which opens the subdev device node. The client capabilities are stored in the file handle of the opened subdev device node, and the client must set the capabilities for each opened subdev. For now we only add a single flag, V4L2_SUBDEV_CLIENT_CAP_STREAMS, which indicates that the client is streams-aware. The reason for needing such a flag is as follows: Many structs passed via ioctls, e.g. struct v4l2_subdev_format, contain reserved fields (usually a single array field). These reserved fields can be used to extend the ioctl. The userspace is required to zero the reserved fields. We recently added a new 'stream' field to many of these structs, and the space for the field was taken from these reserved arrays. The assumption was that these new 'stream' fields are always initialized to zero if the userspace does not use them. This was a mistake, as, as mentioned above, the userspace is required to zero the _reserved_ fields. In other words, there is no requirement to zero this new stream field, and if the userspace doesn't use the field (which is the case for all userspace applications at the moment), the field may contain random data. This shows that the way the reserved fields are defined in v4l2 is, in my opinion, somewhat broken, but there is nothing to do about that. To fix this issue we need a way for the userspace to tell the kernel that the userspace has indeed set the 'stream' field, and it's fine for the kernel to access it. This is achieved with the new ioctl, which the userspace should usually use right after opening the subdev device node.

| | | | | | | | | | | | | | | | | | A common case with subdev routing is that on the subdevice just before the DMA engines (video nodes), no multiplexing is allowed on the source pads, as the DMA engine can only handle a single stream. In some other situations one might also want to do the same check on the sink side. Add new routing validation flags to check these: V4L2_SUBDEV_ROUTING_NO_SINK_MULTIPLEXING and V4L2_SUBDEV_ROUTING_NO_SOURCE_MULTIPLEXING.

* media: subdev: Split V4L2_SUBDEV_ROUTING_NO_STREAM_MIXTomi Valkeinen2023-03-201-3/+14
| | | | | | | | | | | | | | | | | | | | | | V4L2_SUBDEV_ROUTING_NO_STREAM_MIX routing validation flag means that all routes from a sink pad must go to the same source pad and all routes going to the same source pad must originate from the same sink pad. This does not cover all use cases. For example, if a device routes all streams from a single sink pad to any of the source pads, but streams from multiple sink pads can go to the same source pad, the current flag is too restrictive. Split the flag into two parts, V4L2_SUBDEV_ROUTING_NO_SINK_STREAM_MIX and V4L2_SUBDEV_ROUTING_NO_SOURCE_STREAM_MIX, which add the restriction only on one side of the device. Together they mean the same as V4L2_SUBDEV_ROUTING_NO_STREAM_MIX.

| | | | | | | | | | | | | | | | Destructive overlay support (i.e. where the video frame is DMA-ed straight into a framebuffer) is effectively dead. It was a necessary evil in the early days when computers were not fast enough to copy SDTV video frames around, but today that's no longer a problem. It requires access to the framebuffer memory, which is a bad idea and very hard to do safely. In addition, in drm it is today almost impossible to get hold of the framebuffer address.

| | | | | | | | | | | | | | | | | | dvb_net.h includes a bunch of core networking headers which increases the number of objects rebuilt when we touch them. They are unnecessary for the header itself and only one driver has an indirect dependency. tveeprom.h includes if_packet to gain access to ETH_ALEN. This is a bit of an overkill because if_packet.h pulls in skbuff.h. The definition of ETH_ALEN is in the uAPI header, which is very rarely touched, so switch to including that. This results in roughly 250 fewer objects built when skbuff.h is touched (6028 -> 5788).
