Cross-Compiling Rust for aarch64-unknown-linux-musl on GitHub Actions

With vendored OpenSSL + ring (rustls) -- a complete working guide.

The Problem

Cross-compiling Rust projects targeting aarch64-unknown-linux-musl on x86_64 GitHub Actions runners fails when:

1. Using gcc-aarch64-linux-gnu (glibc cross-compiler) with musl target -- vendored OpenSSL gets compiled against glibc headers, introducing symbols like __memcpy_chk, __memset_chk, __vfprintf_chk that don't exist in musl.

# Fetch the submodule commits into the main repository
git remote add submodule_origin git://url/to/submodule/origin
git fetch submodule_origin

# Start a fake merge (won't change any files, won't commit anything)
git merge -s ours --no-commit submodule_origin/master

Sample service script for debianoids

Look at LSB init scripts for more information.

Usage

Copy to /etc/init.d:

# replace "$YOUR_SERVICE_NAME" with your service's name (whenever it's not enough obvious)

zeroows

#! /bin/bash

# HEADS UP! Make sure to use '*' or a valid hostname for the FDQN prompt

echo 01 > ca.srl
openssl genrsa -des3 -out ca-key.pem
openssl req -new -x509 -days 365 -key ca-key.pem -out ca.pem

openssl genrsa -des3 -out server-key.pem
openssl req -new -key server-key.pem -out server.csr
