Hello everyone. I’ve been working with the Open Claw framework for a few months now, primarily focusing on integrating its security tooling with a custom agent orchestration layer. I’ve hit a consistent roadblock during deployment that I haven't seen widely discussed, and I'm hoping someone here might have faced something similar or can spot my misconfiguration.
My setup is a dedicated Ubuntu 22.04 server (bare metal) with a discrete TPM 2.0 chip. The goal is to leverage the TPM for secure key storage as part of a larger, air-gapped research environment where we're fuzzing LLM inference endpoints. The Open Claw documentation suggests it should automatically handle TPM initialization for certain attestation functions, but mine is failing at that first step.
The core error I'm getting during the `openclaw-secure-init` phase is:
```
ERROR: Failed to establish TPM context. Code: 0x80280401 (TPM_E_COMMAND_BLOCKED).
WARNING: Key provisioning fallback disabled. Halting.
```
What I've tried so far:
* Verified the TPM is visible and enabled in the BIOS.
* Confirmed `tpm2-tools` packages are installed and `tpm2_getcap -l` reports the chip is present.
* Ensured the `tss` user and group exist and my process user has the necessary permissions.
* Tried both the default resource manager (`rm -rf /tmp/tpm*`) and the IBM software simulator (which works, but defeats the purpose).
My current `config/security.yaml` relevant section looks like this:
```yaml
hardware_root_of_trust:
enabled: true
provider: "tpm2"
fallback_to_software: false # Intentionally strict for testing
storage_root_key:
hierarchy: "owner"
algorithm: "ecc256"
```
The puzzling part is that direct `tpm2-tools` commands like `tpm2_createprimary -C o -G ecc256 -c primary.ctx` work perfectly fine when run with sudo. This leads me to believe it's a permissions or context issue within Open Claw's own TPM library bindings. Has anyone else deployed Open Claw in a scenario requiring a hardware TPM? Did you need to apply specific kernel parameters, like `tpm_tis.force=1` or play with `udev` rules?
I'm also curious if there's a known interaction with certain Python versions (I'm on 3.10.12) or if the `tpm2-pytss` library version is particularly sensitive. My next step is to dive into the agent framework's internal command logging, but I thought I'd check here first to see if I'm missing a common hardening step. Any pointers would be greatly appreciated.
hardened by default
That error code is the key. TPM_E_COMMAND_BLOCKED usually means the TPM is in a lockout state from too many failed authorization attempts. The framework's "automatic" initialization likely hammered it with bad commands. Did you clear the TPM owner or dictionary attack lockout before you started?
You said the fallback is disabled, which is a problem. The docs gloss over that the default config expects a pristine, initialized TPM, but most real hardware ships with one that's partially owned by the platform. You need to force-clear it with `tpm2_clear -c p` and then check if secure boot state is interfering. After that, the framework's init might work, or it might just expose the next bug.
