Mika,

Thanks for submitting this series.
I've tested security level stuff a little bit,
but I'm running into what I think is some odd behavior.

Here's my setup:
System: I'm using is an XPS 9350 (Has Alpine Ridge). It's got NVM 16.0. BIOS 1.4.13
TBT Device: Dell TB16 (which has AR in the cable and in dock - both NVM 16.0).

I created a udev rule that will automatically authorize the dock and cable.
#dell cable
ACTION=="add", SUBSYSTEM=="thunderbolt", ATTR{authorized}=="0", ATTR{vendor}=="0xd4", ATTR{device}=="0xb051", ATTR{authorized}="1"
#dell dock
ACTION=="add", SUBSYSTEM=="thunderbolt", ATTR{authorized}=="0", ATTR{vendor}=="0xd4", ATTR{device}=="0xb054", ATTR{authorized}="1"

If I boot the system with the dock connected the cable shows up and authorizes but the dock doesn't.
