Restartable Sequences

https://worker.jart.workers.dev/rseq/rseq.png
The best kept secret at the frontier of system programming right now is the Linux 4.18+ (c. 2018) concept of restartable sequences or rseq for short. They allow you to create thread-safe data structures without locks or atomics which scale to microprocessors with many cores. It's currently only possible to use rseq on Linux using handwritten assembly code. However I believe in the future, ...

Frost: [Browser] Fingerprinting Remotely Using OPFS-Based SSD Timing [pdf]

Abstract. Prior work showed that variations in SSD access time can be used to leak information about user activity, e.g., the websites a user ac- cesses, and for covert data transmission. To achieve this, SSD contention side channels require accurate high-resolution timing measurements of I/O operations, e.g., through the io_uring kernel API. However, the impact of these attacks is limited in ...
