Security Fixes

Least Privileged GitHub Actions Token Permissions

The GITHUB_TOKEN is an automatically generated secret to make authenticated calls to the GitHub API. GitHub recommends setting minimum token permissions for the GITHUB_TOKEN.

Pinned Dependencies

GitHub Action tags and Docker tags are mutable. This poses a security risk. GitHub's Security Hardening guide recommends pinning actions to full length commit.

Harden Runner

Harden-Runner is an open-source security agent for the GitHub-hosted runner to prevent software supply chain attacks. It prevents exfiltration of credentials, detects tampering of source code during build, and enables running jobs without sudo access. See how popular open-source projects use Harden-Runner here.

Harden runner usage

You can find link to view insights and policy recommendation in the build log

Please refer to documentation to find more details.

Keeping your actions up to date with Dependabot

With Dependabot version updates, when Dependabot identifies an outdated dependency, it raises a pull request to update the manifest to the latest version of the dependency. This is recommended by GitHub as well as The Open Source Security Foundation (OpenSSF).

Secure Dockerfiles

Pin image tags to digests in Dockerfiles. With the Docker v2 API release, it became possible to use digests in place of tags when pulling images or to use them in FROM lines in Dockerfiles.

Add Dependency Review Workflow

The Dependency Review Workflow enforces dependency reviews on your pull requests. The action scans for vulnerable versions of dependencies introduced by package version changes in pull requests, and warns you about the associated security vulnerabilities. This gives you better visibility of what's changing in a pull request, and helps prevent vulnerabilities being added to your repository.

Maintain Code Quality with Pre-Commit

Pre-commit is a framework for managing and maintaining multi-language pre-commit hooks. Hooks can be any scripts, code, or binaries that run at any stage of the git workflow. Pre-commit hooks are useful for enforcing code quality, code formatting, and detecting security vulnerabilities.

Installing pip packages system-wide is no longer recommended, therefore
we create virtual environment for setting up the build environment for LLVM.
The entire CI test run takes approximately 3 minutes.
The test run fails if there is at least one failed case (failed > 0).

also, ensure NUL terminations here to simplify backend implementations.
(note that, although names with '\0' in the middle are usually valid
in wasm, wamr doesn't support them in general. we might revisit this
later.)

also, add a missing address validation in load_by_name_with_config.

for wasi_ephemeral_nn,

* implement u8 input

* stop dealing with quantization.

  * wasi-nn doesn't have a concept of quantization or pre/post-processing.
    i can't think of any ways to make the backend perform zero-point/scale
    processing without risking to break other applications.

  * there seems to be applications which just use u8 inputs/outputs for
    a quantized model. (see [1] for an example.)
    for certain kinds of inputs/outputs, it usually just works.

this commit keeps the legacy wasi_nn logic intact for now.

tested with [1] with [2] applied.

and "Aix galericulata" seems like a reasonable classification
of the image to my eyes.

There is a scenario where `aot_compile_op_block()` does not prepare a block for
`if`. As a result, the return value of `LLVMBuildPhi()` in
`push_aot_block_to_stack_and_pass_params()` will be dangling, leading to a
memory leak as it cannot be released.

docs: clarify that * and $ in signatures does address conversion

It was non-obvious that `*` means the runtime does the app to native
conversion automatically. With the current docstring, one might assume
that the runtime only does boundary checks and not address conversion.
Under this assumption, passing the already-native address to
`wasm_runtime_addr_app_to_native` will lead to unexpected behavior

As per [this blogpost](https://bytecodealliance.github.io/wamr.dev/blog/understand-the-wamr-stacks/) WAMR does not require a WASM stack in AoT/JIT mode, but `wasm_runtime_exec_env_check` still always expects the size to be > 0
