iirc io_uring also had some pretty significant security issues early on (a couple of years ago). Those should be fixed by now, but that probably dampened adoption as well.
- jeffbee 1y agoNot years ago. io_uring has been a continuous parade of security problems, including a high severity one that wasn't fixed until a few months ago. Many large organizations have patched it out of their kernels on safety basis, which is one of the reasons it suffers from poor adoption.
- raesene9 1y agoLast I checked it's blocked by most container runtimes exactly because of the security problems, and Google blocked io_uring across all their services. I've not checked recently if that's still the case, but https://security.googleblog.com/2023/06/learnings-from-kctf-vrps-42-linux.html https://security.googleblog.com/2023/06/learnings-from-kctf-... has some background.
