The FIELDPIC_FLAG_E bit should be set when field_pic_flag exists in stream, it is currently set based on field_pic_flag of current frame. The PIC_FIELDMODE_E bit is correctly set based on the field_pic_flag. Fix this by setting the FIELDPIC_FLAG_E bit when frame_mbs_only is not set.

A decoded 8-bit 4:2:0 frame need memory for up to 448 bytes per macroblock with additional 32 bytes on multi-core variants. Memory layout is as follow: +---------------------------+ | Y-plane 256 bytes x MBs | +---------------------------+ | UV-plane 128 bytes x MBs | +---------------------------+ | MV buffer 64 bytes x MBs | +---------------------------+ | MC sync 32 bytes | +---------------------------+ Reduce the extra space allocated now that motion vector buffer offset no longer is based on the extra space. Only allocate extra space for 64 bytes x MBs of motion vector buffer and 32 bytes for multi-core sync. Fixes: a9471e25 ("media: hantro: Add core bits to support H264 decoding") Signed-off-by:

A decoded 8-bit 4:2:0 frame need memory for up to 448 bytes per macroblock and is laid out in memory as follow: +---------------------------+ | Y-plane 256 bytes x MBs | +---------------------------+ | UV-plane 128 bytes x MBs | +---------------------------+ | MV buffer 64 bytes x MBs | +---------------------------+ The motion vector buffer offset is currently correct for 4:2:0 because the extra space for motion vectors is overallocated with an extra 64 bytes x MBs. Wrong offset for both destination and motion vector buffer are used for the bottom field of field encoded content, wrong offset is also used for 4:0:0 (monochrome) content. Fix this by setting the motion vector address to the expected 384 bytes x MBs offset for 4:2:0 and 256 bytes x MBs offset for 4:0:0 content. Also use correct destination and motion vector buffer offset for the bottom field of field encoded content. While at it also extend the check for 4:0:0 (monochrome) to include an additional check for High Profile (100). Fixes: dea0a82f ("media: hantro: Add support for H264 decoding on G1") Signed-off-by:

Commit 953aaa14 ("media: rockchip/vpu: Prepare things to support decoders") changed the conditions under S_FMT was allowed for OUTPUT CAPTURE buffers. However, and according to the mem-to-mem stateless decoder specification, in order to support dynamic resolution changes, S_FMT should be allowed even if OUTPUT buffers have been allocated. Relax decoder S_FMT restrictions on OUTPUT buffers, allowing a resolution modification, provided the pixel format stays the same. Tested on RK3288 platforms using ChromiumOS Video Decode/Encode Accelerator Unittests.

There's a race condition between the list_del_init in the v4l2_ctrl_request_complete, and the list_add_tail in the v4l2_ctrl_request_queue, since they can be called in different thread and the requests_queued list is not protected by a lock. This can lead to that the v4l2_ctrl_handler is still in the requests_queued list while the request_is_queued is already set to false, which would cause use-after-free if the v4l2_ctrl_handler is later released. Fix this by locking the ->lock of main_hdl (which is the owner of the requests_queued list) when doing list operations on the ->requests_queued list. Signed-off-by:

An earlier commit hard coded a return 0 to function flexcop_usb_i2c_req even though the an -EIO was intended to be returned in the case where ret != buflen.

In some device configurations there's no radio or radio support in the driver. That's OK, as the driver sets itself up accordingly. However on tear-down in these caes it's still trying to tear down radio related context when there isn't anything there, leading to dereferences through a null pointer and chaos follows. How this bug survived unfixed for 11 years in the pvrusb2 driver is a mystery to me. [hverkuil: fix two checkpatch warnings] Signed-off-by:

v4l2_compat_ioctl32() is the function that calls into v4l2_file_operations->compat_ioctl32(), so setting that back to the same function leads to a trivial endless loop, followed by a kernel stack overrun.

The picture order count table only makes sense for profiles higher than Baseline. This is confirmed by the H.264 specification (See 8.2.1 Decoding process for picture order count), which clarifies how POC are used for features not present in Baseline. """ Picture order counts are used to determine initial picture orderings for reference pictures in the decoding of B slices, to represent picture order differences between frames or fields for motion vector derivation in temporal direct mode, for implicit mode weighted prediction in B slices, and for decoder conformance checking. """ As a side note, this change matches various vendors downstream codebases, including ChromiumOS and IMX VPU libraries.
