2019-10-05media: gspca: zero usb_buf on errorHans Verkuil1-0/+5
[ Upstream commit 4843a543fad3bf8221cf14e5d5f32d15cee89e84 ] If reg_r() fails, then gspca_dev->usb_buf was left uninitialized, and some drivers used the contents of that buffer in logic. This caused several syzbot errors: https://syzkaller.appspot.com/bug?extid=397fd082ce5143e2f67d https://syzkaller.appspot.com/bug?extid=1a35278dd0ebfb3a038a https://syzkaller.appspot.com/bug?extid=06ddf1788cfd048c5e82 I analyzed the gspca drivers and zeroed the buffer where needed.

2013-09-26[media] gspca: store current mode instead of individual parametersOndrej Zary1-3/+3
Store complete current mode (struct v4l2_pix_format) in struct gspca_dev instead of separate pixfmt, width and height parameters. This is a preparation for variable resolution support.
