media: vivid: use vfree() instead of kfree() for dev->bitmap_cap

2019-04-22T15:43:50+00:00

syzkaller reported crashes on kfree() called from vivid_vid_cap_s_selection(). This looks like a simple typo, as dev->bitmap_cap is allocated with vzalloc() throughout the file.

media: replace strncpy() by strscpy()

2019-03-29T14:26:13+00:00

The strncpy() function is being deprecated upstream. Replace it by the safer strscpy(). While here, replace a few occurences of strlcpy() that were recently added to also use strscpy(). Reviewed-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Kconfig files: use the right help coding style

2019-03-20T10:47:51+00:00

Checkpatch wants to use 'help' instead of '---help---': WARNING: prefer 'help' over '---help---' for new help texts Let's change it globally at the media subsystem, as otherwise people would keep using the old way. Signed-off-by: Mauro Carvalho Chehab

media: vivid: use vzalloc for dev->bitmap_out

2019-03-19T17:22:08+00:00

When vivid is unloaded it used vfree to free dev->bitmap_out, but it was actually allocated using kmalloc. Use vzalloc instead, conform what vivid-vid-cap.c does. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: vivid: Add definitions for the 32-bit packed YUV formats

2019-02-18T19:32:42+00:00

Enable vivid to make use of the following formats: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 Signed-off-by: Vivek Kasireddy Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vivid: two unregistration fixes

2019-02-18T17:31:58+00:00

When the media device registration fails, don't call media_device_unregister since the device was never actually registered. When removing the module also call media_device_cleanup() to avoid a memory leak. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: vivid: add vertical down sampling to imagesize calc

2019-02-07T17:24:03+00:00

To correctly set the size of the image in a plane, it's needed to divide the height of image by the vertical down sampling factor. This was only happening in vivid_try_fmt_vid_cap(), but now it applied in others sizeimage calculations as well.

media: vivid: fix vid_out_buf_prepare()

2019-01-31T11:32:05+00:00

The wrong size check was performed for output formats like NV24 which set vfmt->buffers to 1, but vfmt->planes is 2. It was incorrectly checking the payload size for plane 1, which doesn't exist. Note: vfmt->buffers refers to the number of per-plane-buffers that should be allocated. vfmt->planes refers to the number of planes that make up an image. vfmt->planes may be > vfmt->buffers.

media: vivid: add buf_out_validate callback

2019-01-31T11:30:38+00:00

Validate the field for an output buffer. This ensures that the field is validated when the buffer is queued to a request, and not when the request itself is queued, which is too late. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
