Make sure to use the current alternate setting, which need not be the first one by index, when verifying the endpoint descriptors and initialising the URBs. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

In the case where v4l2_event_dequeue fails the structure ev is not being filled and this garbage data from the stack is being copied to the ev32 structure and being copied back to userspace on the VIDIOC_DQEVENT_TIME32 ioctl. Fix this by ensuring the ev structure is zero'd to ensure uninitialized data is not leaked back.

Despite using M2M in both the decoder and encoder, this driver used vb2_v4l2_buffer as its base buffer structure, and placed a list_head right after the buffer declaration in order to match the layout of a v4l2_m2m_buffer. This is very dangerous as it means the driver will break should the layout of v4l2_m2m_buffer change. Fix this by directly using v4l2_m2m_buffer and updating the sites that accessed the buffer accordingly. Signed-off-by:

It seems that for some HEVC videos at least one bitstream parsing trigger must be called in order to be decoded correctly. There is no explanation why this helps, but it was observed that several videos with this fix are now decoded correctly and there is no regression with others. Without this fix, those same videos totally crash HEVC decoder (other decoder engines are unaffected). After decoding those problematic videos, HEVC decoder always returns only green image (all zeros). Only complete HW reset helps. This fix is similar to that for H264. Signed-off-by:

The driver may sleep while holding a spinlock. The function call path (from bottom to top) in Linux 4.19 is: drivers/media/platform/sti/bdisp/bdisp-hw.c, 385: msleep in bdisp_hw_reset drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 341: bdisp_hw_reset in bdisp_device_run drivers/media/platform/sti/bdisp/bdisp-v4l2.c, 317: _raw_spin_lock_irqsave in bdisp_device_run To fix this bug, msleep() is replaced with udelay(). This bug is found by a static analysis tool STCheck written by myself. Signed-off-by:Jia-Ju Bai <baijiaju1990@gmail.com> Reviewed-by:

boundary->width and boundary->height are sizes relative to boundary->left and boundary->top coordinates, but they were not being taken into consideration to adjust r->left and r->top, leading to the following error: Consider the follow as initial values for boundary and r: struct v4l2_rect boundary = { .left = 100, .top = 100, .width = 800, .height = 600, } struct v4l2_rect r = { .left = 0, .top = 0, .width = 1920, .height = 960, } calling v4l2_rect_map_inside(&r, &boundary) was modifying r to: r = { .left = 0, .top = 0, .width = 800, .height = 600, } Which is wrongly outside the boundary rectangle, because: v4l2_rect_set_max_size(r, boundary); // r->width = 800, r->height = 600 ... if (r->left + r->width > boundary->width) // true r->left = boundary->width - r->width; // r->left = 800 - 800 if (r->top + r->height > boundary->height) // true r->top = boundary->height - r->height; // r->height = 600 - 600 Fix this by considering top/left coordinates from boundary.

There were several reports of building failures due to IOVA being selected inconsistently by different drivers. All drivers that are using IOVA API should select it unconditionally in order to avoid the compilation problems, tegra-vde is one of those drivers.
