Use the dma_set_mask_and_coherent helper to set venc DMA bit mask to support 34bits iova space(16GB) that the mt8192 iommu HW support. Whole the iova range separate to 0~4G/4G~8G/8G~12G/12G~16G, regarding which iova range VENC actually locate, it depends on the dma-ranges property of venc dtsi node. Signed-off-by:

The mt8192 iommu support 0~16GB iova. We separate it to four banks: 0~4G; 4G~8G; 8G~12G; 12G~16G. The "dma-ranges" could be used to adjust the bank we locate. If we don't set this property. The default range always is 0~4G. This is optional and only needed in mt8192, the dma ranges should not cross 4G/8G/12G. Here we don't have actual bus/parent concept here. And the iova requirement is for our HW. Thus put the property in our node. Acked-by:

vidioc_try_fmt() does clamp height and width when called on the OUTPUT queue, so clamping them prior to calling this function is redundant. Set the queue's parameters after calling vidioc_try_fmt() so we can use the values it computed. Signed-off-by:

We have 'struct v4l2_subdev_pad_config' which contains configuration for a single pad used for the TRY functionality, and an array of those structs is passed to various v4l2_subdev_pad_ops. I was working on subdev internal routing between pads, and realized that there's no way to add TRY functionality for routes, which is not pad specific configuration. Adding a separate struct for try-route config wouldn't work either, as e.g. set-fmt needs to know the try-route configuration to propagate the settings. This patch adds a new struct, 'struct v4l2_subdev_state' (which at the moment only contains the v4l2_subdev_pad_config array) and the new struct is used in most of the places where v4l2_subdev_pad_config was used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config are changed to instead take v4l2_subdev_state. The changes to drivers/media/v4l2-core/v4l2-subdev.c and include/media/v4l2-subdev.h were written by hand, and all the driver changes were done with the semantic patch below. The spatch needs to be applied to a select list of directories. I used the following shell commands to apply the spatch: dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media" for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done Note that Coccinelle chokes on a few drivers (gcc extensions?). With minor changes we can make Coccinelle run fine, and these changes can be reverted after spatch.

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Use flexible-array members in struct hfi_msg_sys_property_info_pkt and hfi_msg_session_property_info_pkt instead of one-element arrays, and refactor the code accordingly. Also, this helps with the ongoing efforts to enable -Warray-bounds by fixing the following warnings: CC [M] drivers/media/platform/qcom/venus/hfi_msgs.o drivers/media/platform/qcom/venus/hfi_msgs.c: In function ‘hfi_sys_property_info’: drivers/media/platform/qcom/venus/hfi_msgs.c:246:35: warning: array subscript 1 is above array bounds of ‘u32[1]’ {aka ‘unsigned int[1]’} [-Warray-bounds] 246 | if (req_bytes < 128 || !pkt->data[1] || pkt->num_properties > 1) | ~~~~~~~~~^~~ drivers/media/platform/qcom/venus/hfi_msgs.c: In function ‘hfi_session_prop_info’: drivers/media/platform/qcom/venus/hfi_msgs.c:342:62: warning: array subscript 1 is above array bounds of ‘u32[1]’ {aka ‘unsigned int[1]’} [-Warray-bounds] 342 | if (!req_bytes || req_bytes % sizeof(*buf_req) || !pkt->data[1]) | ~~~~~~~~~^~~ [1] https://en.wikipedia.org/wiki/Flexible_array_member [2] https://www.kernel.org/doc/html/v5.9/process/deprecated.html#zero-length-and-one-element-arrays Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/109Co-developed-by:Kees Cook <keescook@chromium.org> Signed-off-by:

Right now, there are two calls for xvip_get_format_by_fourcc(). If the first one fails, it is called again in order to pick the first available format: V4L2_PIX_FMT_YUYV. This ends by producing a smatch warnings: drivers/media/platform/xilinx/xilinx-dma.c:555 __xvip_dma_try_format() error: 'info' dereferencing possible ERR_PTR() drivers/media/platform/xilinx/xilinx-dma.c: drivers/media/platform/xilinx/xilinx-dma.c:664 xvip_dma_init() error: 'dma->fmtinfo' dereferencing possible ERR_PTR() as it is hard for an static analyzer to ensure that calling xvip_get_format_by_fourcc(XVIP_DMA_DEF_FORMAT) won't return an error. So, better to optimize the logic, ensuring that the function will never return an error. Signed-off-by: -

The implementation for FE_SET_PROPERTY/FE_GET_PROPERTY has a debug code that might be explored via spectre. Improve the logic in order to mitigate such risk. It should be noticed that, before this patch, the logic which implements FE_GET_PROPERTY doesn't check the length passed by the user, which might lead to expose some information. This is probably not exploitable, though, as the frontend drivers won't rely on the buffer length value set by userspace, but it helps to return a valid value back to userspace. The code was changed to only try to access an array based on userspace values only when DVB debug is turned on, helping to reduce the attack surface, as a speculation attack would work only if DVB dev_dbg() macros are enabled, which is usually enabled only on test Kernels or by the root user. As a side effect, a const array size can now be reduced by ~570 bytes, as it now needs to contain just the name of each DTV command. Signed-off-by: -

The risk of especulation is actually almost-non-existing here, as there are very few users of TCP/IP using the DVB stack, as, this is mainly used with DVB-S/S2 cards, and only by people that receives TCP/IP from satellite connections, which limits a lot the number of users of such feature(*). (*) In thesis, DVB-C cards could also benefit from it, but I'm yet to see a hardware that supports it. Yet, fixing it is trivial. Signed-off-by: -

As warned by smatch: drivers/media/dvb-core/dvb_ca_en50221.c:1392 dvb_ca_en50221_io_do_ioctl() warn: potential spectre issue 'ca->slot_info' [r] (local cap) There's a potential of using a CAM ioctl for speculation. The risk here is minimum, as only a small subset of DVB boards have CI, with a CAM module installed. Also, exploiting it would require a user capable of starting a DVB application. There are probably a lot of easier ways to try to exploit. Yet, it doesn't harm addressing it. Signed-off-by:

The Elgato Cam Link 4K HDMI video capture card reports to support three different pixel formats, where the first format depends on the connected HDMI device. ``` $ v4l2-ctl -d /dev/video0 --list-formats-ext ioctl: VIDIOC_ENUM_FMT Type: Video Capture [0]: 'NV12' (Y/CbCr 4:2:0) Size: Discrete 3840x2160 Interval: Discrete 0.033s (29.970 fps) [1]: 'NV12' (Y/CbCr 4:2:0) Size: Discrete 3840x2160 Interval: Discrete 0.033s (29.970 fps) [2]: 'YU12' (Planar YUV 4:2:0) Size: Discrete 3840x2160 Interval: Discrete 0.033s (29.970 fps) ``` Changing the pixel format to anything besides the first pixel format does not work: ``` $ v4l2-ctl -d /dev/video0 --try-fmt-video pixelformat=YU12 Format Video Capture: Width/Height : 3840/2160 Pixel Format : 'NV12' (Y/CbCr 4:2:0) Field : None Bytes per Line : 3840 Size Image : 12441600 Colorspace : sRGB Transfer Function : Rec. 709 YCbCr/HSV Encoding: Rec. 709 Quantization : Default (maps to Limited Range) Flags : ``` User space applications like VLC might show an error message on the terminal in that case: ``` libv4l2: error set_fmt gave us a different result than try_fmt! ``` Depending on the error handling of the user space applications, they might display a distorted video, because they use the wrong pixel format for decoding the stream. The Elgato Cam Link 4K responds to the USB video probe VS_PROBE_CONTROL/VS_COMMIT_CONTROL with a malformed data structure: The second byte contains bFormatIndex (instead of being the second byte of bmHint). The first byte is always zero. The third byte is always 1. The firmware bug was reported to Elgato on 2020-12-01 and it was forwarded by the support team to the developers as feature request. There is no firmware update available since then. The latest firmware for Elgato Cam Link 4K as of 2021-03-23 has MCU 20.02.19 and FPGA 67. Therefore correct the malformed data structure for this device. The change was successfully tested with VLC, OBS, and Chromium using different pixel formats (YUYV, NV12, YU12), resolutions (3840x2160, 1920x1080), and frame rates (29.970 and 59.940 fps).

While the logic there is right, it tricks static check analyzers, like smatch: drivers/media/dvb-core/dmxdev.c:729 dvb_dmxdev_filter_start() error: we previously assumed '*secfeed' could be null (see line 719) Because the implementation of the filter itself is made via a callback, with its real implementation at the dvbdmx_allocate_section_feed() inside dvb_demux.c. So, change the check logic to make it clear that the function will not try to use *secfeed == NULL. Signed-off-by:

When the driver fails to talk with the hardware with dvb_usb_generic_rw, it will return an error to dvb_usb_adapter_frontend_init. However, the driver forgets to free the resource (e.g., struct cinergyt2_fe_state), which leads to a memory leak. Fix this by freeing struct cinergyt2_fe_state when dvb_usb_generic_rw fails in cinergyt2_frontend_attach. backtrace: [<0000000056e17b1a>] kmalloc include/linux/slab.h:552 [inline] [<0000000056e17b1a>] kzalloc include/linux/slab.h:682 [inline] [<0000000056e17b1a>] cinergyt2_fe_attach+0x21/0x80 drivers/media/usb/dvb-usb/cinergyT2-fe.c:271 [<00000000ae0b1711>] cinergyt2_frontend_attach+0x21/0x70 drivers/media/usb/dvb-usb/cinergyT2-core.c:74 [<00000000d0254861>] dvb_usb_adapter_frontend_init+0x11b/0x1b0 drivers/media/usb/dvb-usb/dvb-usb-dvb.c:290 [<0000000002e08ac6>] dvb_usb_adapter_init drivers/media/usb/dvb-usb/dvb-usb-init.c:84 [inline] [<0000000002e08ac6>] dvb_usb_init drivers/media/usb/dvb-usb/dvb-usb-init.c:173 [inline] [<0000000002e08ac6>] dvb_usb_device_init.cold+0x4d0/0x6ae drivers/media/usb/dvb-usb/dvb-usb-init.c:287 Reported-by: syzbot+e1de8986786b3722050e@syzkaller.appspotmail.com Signed-off-by:
