The io_uring subsystem was introduced in Linux v5.1 and provided a new way to do asynchronous I/O on Linux, improving on the existing AIO subsystem. Since then io_uring has been a source of active development, gaining the ability to delegate credentials across process boundaries in Linux v5.6. Unfortunately, all of this happened without engaging the LSM community, and as a result LSM access controls were not added to io_uring until Linux v5.16. This talk will discuss the challenges in adding LSM controls to the io_uring subsystem, thoughts on why the controls lagged the functional development, and what the LSM community might do to help reduce the changes of similar problems in the future.
