The MediaDevice::populateLinks() function iterates over data links by skipping interface links. This isn't very future-proof, it will break if the kernel adds new types of links.

2021-12-07libcamera: base: utils: Add abs_diff() utility functionLaurent Pinchart
The abs_diff() function computes the absolute difference of two elements. This may seem trivial at first, but can lead to unexpected results when operating on unsigned operands. A common implementation of the absolute difference of two unsigned int (used through the libcamera code base) is std::abs(static_cast<int>(a - b)) but doesn't return the expected result when either a or b is larger than UINT_MAX / 2 due to overflows. The abs_diff() function offers a safe alternative.

2021-12-07libcamera: base: shared_fd: Don't dup() an invalid fdLaurent Pinchart
The SharedFD::dup() implementation calls the C library dup() function on the fd. When the SharedFD instance is invalid, this produces an invalid fd, which is the correct behaviour, but logs an error message. Fix it by returning an invalid UniqueFD directly when the SharedFD is invalid. This also saves a system call, which is always nice to do.

2021-12-07android: Apply 1% tolerance to minFrameDuration cappingUmang Jain
We have some stream resolution which can provide slightly better frame duration than what we cap (i.e. 1/30 fps). The problem with this is CTS complains if the camera goes faster during the test than minFrameDuration reported for that resolution. For instance, 1080p minFrameDuration: - Nautilus : 33282000ns - Soraka : 33147000ns Both are less than capped minFrameDuration 1/30 fps (33333333.33ns). This patch considers this situation and doesn't cap the minFrameDuration if the hardware can provide frame durations slightly better. The tolerance considered is 1% only from the cap.
