m/n/core/localstorage/crypt: support more enc/auth modes

This is in preparation for introducing configurable disk
encryption/authentication policies in Metropolis (eg. low integrity
mode).

We also use the opportunity to add some tests for the newly refactored
crypt library. All modes go through an end-to-end test making sure data
is preserved and repeatedly mapping/unmapping the device works.

This change also disables insecure mode in debug builds. The equivalent
functionality will be re-established at a higher level in the cluster
code in a subsequent change, alongside the encryption/authentication
policy code.

Monogon Monorepo

This is the main repository containing the source code for the Monogon Platform.

This is pre-release software - take a look, and check back later!

Environment

Our build environment is self-contained and requires only minimal host dependencies:

  • A Linux machine or VM.
  • Bazelisk >= v1.15.0
  • A reasonably recent kernel with user namespaces enabled.
  • Working KVM with access to /dev/kvm (if you want to run tests).

Our docs assume that Bazelisk is available as bazel on your PATH.

Refer to SETUP.md for detailed instructions.

Monogon OS

Run a single node demo cluster

Build CLI and node image:

bazel build //metropolis/cli/dbg //:launch -c dbg

Launch an ephemeral test node:

bazel test //:launch -c dbg --test_output=streamed

Run a kubectl command while the test is running:

bazel-bin/metropolis/cli/dbg/dbg_/dbg kubectl describe node

Test suite

Run full test suite:

bazel test -c dbg //...
