I don't know if any of this is expected.
Now that I've written iouring.4, I would skip the others; while helpful at the time, they are pretty crap. I have no idea what kernel you are running, but I'm going to assume you've applied the v2 patches (if not, you obviously need to do that <g>). Beyond that you may need to set a filter for the io_uring_enter() syscall to force the issue; theoretically your audit userspace patches should allow a uring op specifically to be filtered but I haven't had a chance to try that yet so either the kernel or userspace portion could be broken. At this point if you are running into problems you'll probably need to spend some time debugging them, as I think you're the only person who has tested your audit userspace patches at this point (and the only one who has access to your latest bits). -- paul moore www.paul-moore.com -- Linux-audit mailing list Linux-audit@redhat.com https://listman.redhat.com/mailman/listinfo/linux-audit
