2021-06-08media: uapi: Add a control for HANTRO driverBenjamin Gaignard3-0/+33
The HEVC HANTRO driver needs to know the number of bits to skip at the beginning of the slice header. That is a hardware specific requirement so create a dedicated control for this purpose.

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: Dongliang Mu <mudongliangabcd@gmail.com> Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Use the new vb2_queue_change_type() function in .vidioc_reqbufs and .vidioc_create_bufs instead of changing the queue type manually in vidioc_s_fmt_vbi_cap() and vidioc_s_fmt_sliced_vbi_cap(). This allows for a more consistent behavior, as .vidioc_reqbufs and .vidioc_create_bufs are when the queue will become "busy".

2021-06-08media: vivid: remove stream_sliced_vbi_cap fieldTomi Valkeinen3-6/+3
Vivid tracks the VBI capture mode in vivid_dev->stream_sliced_vbi_cap field. We can just look at the buffer type instead, and drop the field.

2021-06-08media: videobuf2-v4l2.c: add vb2_queue_change_type() helperTomi Valkeinen2-0/+30
On some platforms a video device can capture either video data or metadata. The driver can implement vidioc functions for both video and metadata, and use a single vb2_queue for the buffers. However, vb2_queue requires choosing a single buffer type, which conflicts with the idea of capturing either video or metadata. The buffer type of vb2_queue can be changed, but it's not obvious how this should be done in the drivers. To help this, add a new helper function vb2_queue_change_type() which ensures the correct checks and documents how it can be used.
