Hacker NewsBusterMQ, Thread-per-core NATS server in Zig with io_uring
Paul RichardsIf I have a single threaded application using io_uring submit a batch of file reads then wait for them all to complete, and if _all_ the data being read was already in the page cache, then is it the case that no parallelism occurs?
As I understand it parallelism on file reads only occurs if data has to be read from the device, and it’s in the form of multiple reads being sent off to the storage hardware in parallel (or at least with QD > 1).

PostgreSQL Database Lands Initial Support For IO_uring: "Can Be Considerably Faster"
As a very exciting improvement for the open-source PostgreSQL database server, it has merged initial support for making use of IO_uring on Linux servers for asynchronous I/O and can provide for some nice performance improvements.

Mind the Patch Gap: Exploiting an io_uring Vulnerability in Ubuntu - Exodus Intelligence
By Oriol Castejón Overview This post discusses a use-after-free vulnerability, CVE-2024-0582, in io_uring in the Linux kernel. Despite the vulnerability being patched in the stable kernel in December 2023, it wasn’t ported to Ubuntu kernels for over two months, making it an easy 0day vector in Ubuntu during that time. In early January 2024, a Project Zero issue ... Read more Mind the Patch Gap: Exploiting an io_uring Vulnerability in Ubuntu

Chances are you might have heard of io_uring. It first appeared in Linux 5.1, back in 2019, and was advertised as the new API for asynchronous I/O. Its goal was to be an alternative to the deemed-to-be-broken-beyond-repair AIO, the “old” asynchronous I/O API
