That looks like a fundamental technical limitation in my book - to an open
source
user this is essentially a very similar capability as tboot: it only allows the
execution of externally blessed static binary blobs...
I don't think we can merge any of this upstream until it's clear that the
hardware
owner running open-source user-space can also freely define/start his own
secure
enclaves without having to sign the enclave with any external party. I.e.
self-signed enclaves should be fundamentally supported as well.
Thanks,
Ingo
