A few years ago developers knew eBPF as a handy way to build firewalls yet now it's used everywhere for everything. Get ready for io_uring to do the same. . Most people don't know the first thing about Linux under the hood. Why should they? Linux, more so than most operating systems, just works. There's no need to poke inside it. But beneath the surface, there are programs such as eBPF that are transforming the infrastructure under the operating system we use every day. As revealed this week, Microsoft chose to port eBPF into Windows rather than try to duplicate its functionality with its own program. io_uring may become the next Swiss-Army tool for Linux developers. . The rise of io_uring signifies a crucial shift in Linux programming, enhancing asynchronous I/O with a streamlined, efficient interface that reduces overhead. io_uring, Linux Development, Development Tools, Programming, Kernel Features. .

It was a very busy year in kernel space from mitigating security vulnerabilities to preparing new features. Here is a look back at the most popular kernel topics of this year. . The year started off on a difficult foot due to all the Spectre/Meltdown mitigation work and following that work on recovering lost performance. The year improved with many new kernel features and new hardware support being introduced, cleaning up of old CPU architectures and other deprecated code, and continuing on plenty of exciting work. But there was also more controversy mixed in from the short-lived Speck encryption code in the kernel that was developed by the NSA to the recent introduction of a "Code of Conduct".
