linux-toradex.git/drivers/media, branch tegra-10.8.3 Linux kernel for Apalis and Colibri modules tegra_uvc: graceful exit on usb camera unplug 2010-06-25T07:10:32+00:00 Sachin Nikam snikam@nvidia.com 2010-06-25T06:58:38+00:00 9e89276dc1ae902a814aca973709ff0724f6f059 Bug 657105 Problem:When the USB Camera is unplugged while preview VIDIOC_DQBUF ioctl hangs in uvc_queue_waiton() as it waits on interrupt which will never come, as USB Camera is unplugged. Solution:Using wait_event_interruptible_timeout() instead of wait_event_interruptible() in function uvc_queue_waiton() with timeout value 250 mSec so as to gracefully exit. With this change VIDIOC_DQBUF ioctl returns error, USB Camera driver handles this error to gracefully exit.

Bug 657105

Problem:When the USB Camera is unplugged while preview
VIDIOC_DQBUF ioctl hangs in uvc_queue_waiton()
as it waits on interrupt which will never come,
as USB Camera is unplugged.

Solution:Using wait_event_interruptible_timeout() instead
of wait_event_interruptible() in function uvc_queue_waiton()
with timeout value 250 mSec so as to gracefully exit.

With this change VIDIOC_DQBUF ioctl returns error,
USB Camera driver handles this error to gracefully exit.

V4L/DVB: dvb-core: fix initialization of feeds list in demux filter 2010-02-23T15:37:51+00:00 Francesco Lavra francescolavra@interfree.it 2010-02-07T12:49:58+00:00 134bb65d8d9fa4e8bf3a7637e983e8d01e063544 commit 691c9ae099b9bcb5c27125af00a4a90120977458 upstream. A DVB demultiplexer device can be used to set up either a PES filter or a section filter. In the former case, the ts field of the feed union of struct dmxdev_filter is used, in the latter case the sec field of the same union is used. The ts field is a struct list_head, and is currently initialized in the open() method of the demux device. When for a given demuxer a section filter is set up, the sec field is played with, thus if a PES filter needs to be set up after that the ts field will be corrupted, causing a kernel oops. This fix moves the list head initialization to dvb_dmxdev_pes_filter_set(), so that the ts field is properly initialized every time a PES filter is set up.
