@mic92:nixos.dev@mic92:nixos.devI just stumbled over this features for the first time when modifying some runc hypervisor.15:48:29
@andi:kack.itandi- we could have a disallowedRequisites = [ kernel.signingKey ]; as very minimal "safety" against having the key world readable on the system (by accident). That is obviously not a silver bullet. Everyone that can build software against the systems nixpkgs checkout could generate properly signed modules and given that it would have to be deterministic you could probably just generate the key "offline" on another box.. 15:52:46
@andi:kack.itandi-What exactly are we gaining again? :D15:52:55
@mic92:nixos.dev@mic92:nixos.devSo would need an activation phase that signs all keys afterwards?16:10:35

@grahamc:nixos.org@grahamc:nixos.orgthe work I'm doing around secureboot support is based on a more involved bootloader "install" step which could support signing modules19:47:39

     tpm2_unseal -c ${dev.tpm2KeyFile.persistentObject} -p ${dev.tpm2KeyFile.authString} > /crypt-ramfs/tpm/unsealed

@grahamc:nixos.org@grahamc:nixos.orgI'm thinking this should be starting an auth session (I think that is the right term) and using the session key for subsequent calls so that the channel with the TPM is all encrypted14:48:23
@grahamc:nixos.org@grahamc:nixos.orgis tpm2_startauthsession the command which does that?14:48:52
