2023-03-20media: v4l2-core: drop v4l2_window clipping and bitmap supportHans Verkuil2-118/+25
There are no longer any drivers that support clipping and bitmap support for the capture or output overlay interfaces, so drop this. Always set the bitmap, clips and clipcount fields to 0, and remove the compat32 support. Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>

Rather than checking which device type it is, just check the STREAMING cap since that indicates support for streaming ioctls. Some drivers only support READWRITE (typically MPEG encoders). Signed-off-by: Hans Verkuil <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
2023-03-18media: v4l: subdev: Make link validation saferSakari Ailus1-0/+10
Link validation currently accesses invalid pointers if the link passed to it is not between two sub-devices. This is of course a driver bug. Ignore the error but print a warning message, as this is how it used to work previously.

2023-03-18media: subdev: Fix validation state lockdep issueTomi Valkeinen1-30/+52
The new subdev state code has a possible deadlock scenario during link validation when the pipeline contains subdevs that support state and that do not support state. The current code locks the states of the subdevs on both ends of the link when starting the link validation, locking the sink side first, then the source. If either (or both) of the subdevs does not support state, nothing is done for that subdev at this point, and instead the locking is handled the old way, i.e. the subdev's ops do the locking internally. The issue arises when the sink doesn't support state, but source does, so the validation code locks the source for the duration of the validation, and then the sink is locked only when the get_fmt op is called. So lockdep sees the source locked first, then the sink. Later, when the streaming is started, the sink's s_stream op is called, which probably takes the subdev's lock. The op then calls the source's s_stream, which takes the source's lock. So, the sink is locked first, then the source. Note that link validation and stream starting is not done at the same time, so an actual deadlock should never happen. However, it's still a clear bug. Fix this by locking the subdev states only if both subdevs support state. In other words, we have two scenarios: 1. Both subdevs support state. Lock sink first, then source, and keep the locks while validating the link. 2. At least one of the subdevs do not support state. Take the lock only for the duration of the operation (get_fmt or looking at the routing), and release after the op is done. Obviously 1. is better, as we have a more consistent view of the states of the subdevs during validation. 2. is how it has been so far, so it's no worse than this used to be.

2023-02-26media: v4l2-subdev.c: clear stream fieldHans Verkuil1-0/+15
Both userspace and kernelspace can pass structs with an uninitialized 'stream' field. Since the check_state() function checks for a non-zero stream field, suddenly these calls will fails with -EINVAL. So check in the wrapper functions in v4l2-subdev.c (which are used by both the kernel and userspace API) if V4L2_SUBDEV_FL_STREAMS is set, and if not, then zero the stream field. Currently no drivers set V4L2_SUBDEV_FL_STREAMS, so the stream field will always be set to 0. This patch might well be reverted in the future when streams support is fully enabled and we finalized the userspace API support for this feature.

GUP now supports reliable R/O long-term pinning in COW mappings, such that we break COW early. MAP_SHARED VMAs only use the shared zeropage so far in one corner case (DAXFS file with holes), which can be ignored because GUP does not support long-term pinning in fsdax (see check_vma_flags()). Consequently, FOLL_FORCE | FOLL_WRITE | FOLL_LONGTERM is no longer required for reliable R/O long-term pinning: FOLL_LONGTERM is sufficient.

Sanity checks were added to verify the v4l2_bt_timings blanking fields in order to avoid integer overflows when userspace passes weird values. But that assumed that userspace would correctly fill in the front porch, backporch and sync values, but sometimes all you know is the total blanking, which is then assigned to just one of these fields. And that can fail with these checks. So instead set a maximum for the total horizontal and vertical blanking and check that each field remains below that. That is still sufficient to avoid integer overflows, but it also allows for more flexibility in how userspace fills in these fields.

Use the proper dma_mmap_coherent helper instead, and stop passing __GFP_COMP to dma_alloc_coherent, as the memory management inside the DMA allocator is hidden from the callers and does not require it.
