media: davinci/vpbe: array underflow in vpbe_enum_outputs()

2020-01-29T09:24:24+00:00

[ Upstream commit b72845ee5577b227131b1fef23f9d9a296621d7b ] In vpbe_enum_outputs() we check if (temp_index >= cfg->num_outputs) but the problem is that "temp_index" can be negative. This patch changes the types to unsigned to address this array underflow bug.

[media] media: videobuf2: Restructure vb2_buffer

2015-10-01T12:04:43+00:00

Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer. Add new member variables - bytesused, length, offset, userptr, fd, data_offset - to struct vb2_plane in order to cover all information of v4l2_plane. struct vb2_plane { unsigned int bytesused; unsigned int length; union { unsigned int offset; unsigned long userptr; int fd; } m; unsigned int data_offset; } Replace v4l2_buf with new member variables - index, type, memory - which are common fields for buffer management. struct vb2_buffer { unsigned int index; unsigned int type; unsigned int memory; unsigned int num_planes; struct vb2_plane planes[VIDEO_MAX_PLANES]; }; v4l2 specific fields - flags, field, timestamp, timecode, sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c struct vb2_v4l2_buffer { struct vb2_buffer vb2_buf; __u32 flags; __u32 field; struct timeval timestamp; struct v4l2_timecode timecode; __u32 sequence; }; Signed-off-by: Junghak Sung Signed-off-by: Geunyoung Kim Acked-by: Seung-Woo Kim Acked-by: Inki Dae Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] platform: Make use of media_bus_format enum

2014-11-14T19:54:08+00:00

In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in all platform drivers.

[media] media: davinci: vpbe: use helpers provided by core if streaming is started

[media] dm644x_ccdc: use unsigned long for fpc_table_addr

2014-08-26T21:52:03+00:00

The fpc_table_addr is used as an unsigned integer that stores an address. At the Kernel, the proper type for such integers is unsigned long. This generates lots of warnings when compiling on 64 bits. Signed-off-by: Mauro Carvalho Chehab
