2022-05-13media: stkwebcam: move stk_camera_read_reg() scratch buffer to struct stk_cameraTom Rix2-9/+4
In stk_camera_read_reg() a single byte buffer is alloc-ed and freed on every function call. Since the size is known, move the buffer to the struct stk_camera where it will be alloc-ed and freed once.

2022-05-13media: pvrusb2: fix array-index-out-of-bounds in pvr2_i2c_core_initPavel Skripkin1-2/+5
Syzbot reported that -1 is used as array index. The problem was in missing validation check. hdw->unit_number is initialized with -1 and then if init table walk fails this value remains unchanged. Since code blindly uses this member for array indexing adding sanity check is the easiest fix for that. hdw->workpoll initialization moved upper to prevent warning in __flush_work.

2022-05-08media: uvcvideo: Add UVC_GUID_FORMAT_H265James_Lin2-0/+8
This patch aims to add UVC_GUID_FORMAT_H265 High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2. They describe the same video encoding method. So for handling their behavior is the same. However, when external camera device describes this encoding method, some use hevc, some use h265. There is no uniform specification to describe this encoding method. So if an external camera device use h265 to describe this encoding method, driver will not recognize it. Therefore, this patch is to enable driver to read HEVC/H265 and convert it to V4L2_PIX_FMT_HEVC.

2022-05-08media: uvcvideo: Fix missing check to determine if element is found in listXiaomeng Tong1-9/+11
The list iterator will point to a bogus position containing HEAD if the list is empty or the element is not found in list. This case should be checked before any use of the iterator, otherwise it will lead to a invalid memory access. The missing check here is before "pin = iterm->id;", just add check here to fix the security bug. In addition, the list iterator value will *always* be set and non-NULL by list_for_each_entry(), so it is incorrect to assume that the iterator value will be NULL if the element is not found in list, considering the (mis)use here: "if (iterm == NULL". Use a new value 'it' as the list iterator, while use the old value 'iterm' as a dedicated pointer to point to the found element, which 1. can fix this bug, due to 'iterm' is NULL only if it's not found. 2. do not need to change all the uses of 'iterm' after the loop. 3. can also limit the scope of the list iterator 'it' *only inside* the traversal loop by simply declaring 'it' inside the loop in the future, as usage of the iterator outside of the list_for_each_entry is considered harmful. https://lkml.org/lkml/2022/2/17/1032 Fixes: d5e90b7a6cd1c ("[media] uvcvideo: Move to video_ioctl2") Signed-off-by: Xiaomeng Tong <xiam0nd.tong@gmail.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

2022-03-18media: Kconfig: cleanup VIDEO_DEV dependenciesMauro Carvalho Chehab18-71/+71
media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

hdpvr_register_videodev is responsible to initialize a worker in hdpvr_device. However, the worker is only initialized at hdpvr_start_streaming other than hdpvr_register_videodev. When hdpvr_probe does not initialize its worker, the hdpvr_disconnect will encounter one WARN in flush_work.The stack trace is as follows: hdpvr_disconnect+0xb8/0xf2 drivers/media/usb/hdpvr/hdpvr-core.c:425 usb_unbind_interface+0xbf/0x3a0 drivers/usb/core/driver.c:458 __device_release_driver drivers/base/dd.c:1206 [inline] device_release_driver_internal+0x22a/0x230 drivers/base/dd.c:1237 bus_remove_device+0x108/0x160 drivers/base/bus.c:529 device_del+0x1fe/0x510 drivers/base/core.c:3592 usb_disable_device+0xd1/0x1d0 drivers/usb/core/message.c:1419 usb_disconnect+0x109/0x330 drivers/usb/core/hub.c:2228 Fix this by moving the initialization of dev->worker to the starting of hdpvr_register_videodev Reported-by: syzkaller <syzkaller@googlegroups.com> Signed-off-by: Dongliang Mu <mudongliangabcd@gmail.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2022-03-07media: stk1160: use dma_alloc_noncontiguous APIDafna Hirschfeld3-44/+84
Replace the urb buffers allocation to use the noncontiguous API. This improves performance on ARM platforms where DMA coherent allocations produce uncached mappings. Note that the noncontiguous API requires the driver to handle synchronization. This commit is similar to this one for the uvc driver: https://lkml.org/lkml/2021/3/12/1506 Performance tests on rock-pi4 (Arm64) shows about 15x improvements: == DMA NONCONTIGUOUS == total durations: 20.63678480 sec urb processing durations: 0.286864889 sec uS/qty: 286864/2508 avg: 114.379 min: 0.583 max: 155.461 (uS) FPS: 24.92 lost: 0 done: 500 raw decode speed: 11.603 Gbits/s bytes 414831228.000 bytes/urb: 165403 == DMA COHERENT == total durations: 20.73551767 sec urb processing durations: 4.541559160 sec uS/qty: 4541559/2509 avg: 1810.107 min: 0.583 max: 2113.163 (uS) FPS: 24.90 lost: 0 done: 500 raw decode speed: 730.738 Mbits/s bytes 414785444.000 bytes/urb: 165319 Performance tests on x86 laptop show no significant difference: == DMA NONCONTIGUOUS == total durations: 20.220590102 sec urb processing durations: 0.63021818 sec uS/qty: 63021/2512 avg: 25.088 min: 0.138 max: 146.750 (uS) FPS: 24.72 lost: 0 done: 500 raw decode speed: 52.751 Gbits/s bytes 415421032.000 bytes/urb: 165374 == DMA COHERENT == total durations: 20.220475614 sec urb processing durations: 0.64751972 sec uS/qty: 64751/2512 avg: 25.777 min: 0.168 max: 132.250 (uS) FPS: 24.72 lost: 0 done: 500 raw decode speed: 51.927 Gbits/s bytes 415422794.000 bytes/urb: 165375 [hverkuil: incorporated Ezequiel's suggestions from his review] Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> Reviewed-by: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>

Instead of having two separated arrays, one for the urbs and one for their buffers, have one array of a struct containing both. In addition, the array is just 16 pointers, no need to dynamically allocate it.

2022-03-07media: stk1160: If start stream fails, return buffers with VB2_BUF_STATE_QUEUEDDafna Hirschfeld3-7/+7
If the callback 'start_streaming' fails, then all queued buffers in the driver should be returned with state 'VB2_BUF_STATE_QUEUED'. Currently, they are returned with 'VB2_BUF_STATE_ERROR' which is wrong. Fix this.
