Io_uring and seccomp (2022) (0x74696d.com)
Recent Linux kernels have the kqueue-alike io_uring interface for asynchronous I/O. Instead of making read and write syscalls, you write batches of I/O requests to a circular buffer in userland called the submission queue, and make a io_uring_enter syscall to submit them to the kernel. Instead of making individual syscalls, io_uring submission queue entries (SQEs) take an opcode for the specific I/O operation they're performing, and that's mapped to the same kernel code that normally services the syscall.
