Improve efficiency and throughput of virtqueue operations

1

The current implementation is very simple, but involves copies of buffers that could be avoided. We should also experiment with different queue lenghts and buffer sizes to optimise throughput.

Decide on approach when the trusted runtime receives invalid data from the untrusted launcher

Some examples include: - Invalid lengths/indices in the used elements of a virtqueue - Invalid vsock packet lengths - Invalid lengths for custom framing and object serialisation We could ignore...

ABI function for iterating over all the keys in the lookup data

6

This may be useful for use cases in which the code is trying to find the best (e.g. closest) item in the list of items.

Sign provenances in Oak

1

We currently [generate Amber provenances for every commit](#2524) merged to the main branch. We want the GitHub action that generates the provenances to also sign them. As a starting point,...
