raitobezarius | 2.6.1, 2.6.2, 2.6.3 | 13:18:10 |
raitobezarius | It's indeed the "reference code" provided in the specification | 13:18:27 |
@grahamc:nixos.org | ah, ok, cool, so the code is in the spec, but as a reference and not actually the rules of how a tpm must operate | 13:18:53 |
raitobezarius | Yeah, it's not protocol-level vuln I suppose | 13:19:03 |
@grahamc:nixos.org | whew | 13:19:28 |
raitobezarius | cc baloo if you can bump libtpms in nixpkgs | 13:34:23 |
baloo | Yeah the spec also provide a sample implementation. I know libtpms just imports that.
I don’t know if the spec mandates that you use this implementation | 15:24:11 |
baloo | What I can tell you is that it is sometimes easier to go look at the code to make sense of the spec (especially around credentials) | 15:24:48 |
baloo | Yeah I’ll bump the libtpms | 15:26:28 |
baloo | https://github.com/NixOS/nixpkgs/pull/219016 | 16:34:32 |
baloo | now the fun begins: sending that to vendors of TPMs and see if they are affected :D | 16:54:40 |
baloo | got beat to it, but I don't think I can share the response from vendor.
But I can say our product is not affected? | 17:06:43 |
baloo | make of that what you will | 17:06:51 |
Julian Stecklina (Old) | baloo: where are you actually working at? :) (If you want to share) | 17:15:42 |
baloo | arista networks | 17:15:56 |
baloo | the NDR division deploys nixos in production | 17:16:58 |
Julian Stecklina (Old) | Ah, nice | 17:17:07 |

raitobezarius | ElvishJerricco: so you have TPM2 unlock with systemd-measure for PCRs? | 13:06:47 |
ElvishJerricco | raitobezarius: Yea, using https://github.com/DeterminateSystems/bootspec-secureboot/pull/240 | 13:10:49 |
raitobezarius | alright I might port this to lanzaboote | 13:17:10 |
