rust-libutee

Introduction

rust-libutee is a Rust wrapper for libutee, providing Rust bindings and utilities to interact with the TEE user-mode TEE runtime.

Feature: xtee-panic-notify

For x-kernel TAs hosted by xtee-utee, enable this feature (or depend on xtee-utee, which enables it) so TEE_Panic calls xtee_ta_panic_notify and the CA receives TEE_ERROR_TARGET_DEAD on the in-flight invoke connection.

Without this feature, _utee_panic only spins in a loop (no undefined symbols when publishing or building standalone src/bin/* tools).

rust-libutee = { version = "0.1", features = ["xtee-panic-notify"] }
# xtee-utee enables this on its rust-libutee dependency automatically.

Prerequisites

Before building the project, ensure that the required cross-compilers are available in your PATH.

Example:

export PATH=/home/data/tools/aarch64-linux-musl-cross/bin:$PATH
export PATH=/home/data/tools/x86_64-linux-musl-cross/bin:$PATH

Build

Clone the repository:

git clone <repository-url> 

cd rust-libutee

Build the project:

cargo build

Build for a specific target (example: x86_64-unknown-linux-musl):

cargo build --target x86_64-unknown-linux-musl
