There was a problem hiding this comment.
Please submit this patches upstream to libuio for review and comment and add Upstream-Status: tag to the patch header.
Secondly, apply the patch directly in bb file no need to do it via a bbappend.
The function uio_line_from_file() fails to close the FILE pointer when fgets() returns NULL, causing a file descriptor leak. This can be triggered when reading from /sys files that return empty content, leading to resource exhaustion over time. Fix this by using goto-based error handling to ensure fclose() is called on all exit paths. Signed-off-by: Qliangw <qili00001@gmail.com>
