Hi everyone, our kernel APIs are not as good as they were years back. There are a bunch of the management commands that are actually broken. And they have been broken for years now. For example Set Device Class, Load Long Term Keys, Confirm Name and maybe even others. Some commands are really relaxing when it comes to accept certain input variables and turning them into booleans. Which is also a bad idea. This all has to stop. From now on, I do not want to see any kernel API additions (management or socket) that we do not have a proper testing tool for that can verify its correct behavior. Also adding new APIs until we have verified the old ones is not something I like to do either. During the holidays I started a tool called mgmt-tester that allows end-to-end testing of the management interface by using emulated HCI controllers. You just need to load hci_vhci kernel module and run it. There is a lot of extra work to do for actually ensuring that we are sending the right HCI commands on different controller versions, but it is possible to verify this since it is all emulated. Nobody needs the latest hardware. Look into the emulator directory for my effort in providing flexible support for simulating different behaviors. This work of testing our APIs needs to be done NOW. So instead of everybody trying to squeeze in the latest features, I rather see the core being improved first and made rock solid. I welcome every patch that tries to improve this situation.
