(Updated as per Nea's suggestion in the mailing list, to reflect that for the agent, we want either the python or the rust-based agent installed, not both concurrently.)

Keylime subpackaging and agent alternatives

Summary

The keylime package will be split into subpackages per role (agent, registrar, verifier, and admin components), while allowing the alternative agent implementation in Rust.

Owner


Current status

Detailed Description

The current Keylime package available in Fedora provides all the components as a single package. To support the usage scenarios where only agent or management component is deployed on a specific host, we plan to split the package into subpackages per role. This change also enables the alternative Keylime agent implementation in Rust, which will eventually be preferred over the Python implementation.

Feedback

Benefit to Fedora

This makes it easier to deploy Keylime agent in IoT or Fedora CoreOS spins and thus enable remote attestation without installing full dependencies of Keylime.

Scope

  • Proposal owners:
    • The keylime package will provide subpackages (keylime-agent, keylime-registrar, etc)
    • The keylime package will be a meta package that will install all the subpackages
    • The Rust based agent will be packaged along with its build dependencies
    • Both keylime-agent implementations, one written in Python, the other written in Rust, will be selectively installable through RPM's installable alternatives framework, similar to how we can select beween PipeWire/PulseAudio and pipewire-media-session/wireplumber.
  • Other developers: N/A (not a System Wide Change)
  • Policies and guidelines: N/A (not needed for this Change)
  • Trademark approval: N/A (not needed for this Change)
  • Alignment with Objectives:

Upgrade/compatibility impact

The keylime package will remain as a meta package for the compatibility with the current packaging.

How To Test

  1. Make sure that your systems meet the requirement to run either Keylime agent or other components, as described in the documentation
  2. Install the subpackages individually and see if they function as expected
  3. Install the meta package (keylime) and see if it pulls all the subpackages
  4. Selectively install a package that provides the keylime-agent functionality: either keylime-agent-rust (Rust-based) or (python-)keylime-agent (Python-based); they should conflict with each other, so that we should have only one of them installed at a time
