IIUC, this would require support for multiple trusted keys backends at
runtime but currently the trusted keys subsystem only supports a
single backend which is selected via kernel module parameter during
boot.
So the trusted keys framework needs to evolve to support multiple
trust sources at runtime but I would like to understand the use-cases
first. IMO, selecting the best trust source available on a platform
for trusted keys should be a one time operation, so why do we need to
have other backends available at runtime as well?
I thought about devices with a TPM-Chip and CAAM.
IMHO allowing only one backend at the same time is a little over simplified.
Thanks,
