Certain syscalls like recvmmsg support 64 bit timespec values for the X32 ABI. The helper function compat_put_timespec converts a timespec value to a 32 bit or 64 bit value depending on what ABI is used. The v4l2 compat layer, however, is not designed to support 64 bit timespec values and always uses 32 bit values. Hence, compat_put_timespec must not be used. Without this patch, user space will be provided with bad timestamp values from the VIDIOC_DQEVENT ioctl. Also, fields of the struct v4l2_event32 that come immediately after timestamp get overwritten, namely the field named id.

Commit b2787845 ("V4L/DVB (5289): Add support for video output overlays.") added the field global_alpha to struct v4l2_window but did not update the compat layer accordingly. This change adds global_alpha to struct v4l2_window32 and copies the value for global_alpha back and forth. Signed-off-by:

These can only be accessed with CAP_SYS_ADMIN so it's not a critical security issue. The problem is that "page" is controlled by the user in the ioctl(). The test to see if the bit is set in state->info->page_mask is not sufficient because "page" can be very high and shift wrap around to a bit which is set. Signed-off-by:

vpbe_dev_ops is only copied into the ops field at the end of a vpbe_device structure, so it can be const. Signed-off-by:

24 GPIO pins from 32 available on solo6x10 chips are exported to gpiolib. First 8 GPIOs are reserved for internal use on capture card boards, GPIOs in range 8:15 are configured as outputs to control relays, remaining 16:31 are configured as inputs to read sensor states. Now with this patch userspace DVR software can switch relays and read sensor states when GPIO extension cards are attached to Softlogic solo6x10 based video capture cards. Signed-off-by:

The description of how messages are processed by the core was not always very clear. Reword it to improve this. In particular for the USER_CONTROL_* messages a critical bit was missing in that the core also checks for the CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag. This was confusing. Signed-off-by:
