upx/misc/podman/test-qemu

test-qemu with Podman

This directory provides some simple scripts for creating and running quite small Alpine Linux container images, intended for testing statically-linked Linux executables with Podman and qemu-user.

Very short usage instructions follow.

Where do I get statically-linked Linux binaries:

• all recent official UPX linux release binaries are statically linked
• the zigcc linux-musl artifacts as created by our GitHub Actions CI
• many other linux-musl binaries are statically linked
• many Go and some Rust programs are statically linked

PREPARATION OUTSIDE THE CONTAINER:

    cd your-upx-top-level-directory
    mkdir -p tmp
    cd tmp

    # download official UPX release binaries
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-amd64_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-arm64_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-armeb_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-arm_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-i386_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-mipsel_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-mips_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-powerpc64le_linux.tar.xz
    wget https://github.com/upx/upx/releases/download/v4.0.2/upx-4.0.2-powerpc_linux.tar.xz

    # and unpack all .tar.xz files
    for f in ./upx*.tar.xz; do tar -xJf $f; done

INSIDE THE CONTAINER:

    cd /home/upx/src/upx/tmp

    # check that the official UPX release binaries do work
    qemu-i386 ./upx-4.0.2-i386_linux/upx --version
    qemu-mips ./upx-4.0.2-mips_linux/upx --version
    # ...same for more architectures

    # use qemu-mips to unpack the arm64 binary, and then run the unpacked arm64 binary:
    qemu-mips ./upx-4.0.2-mips_linux/upx -d upx-4.0.2-arm64_linux/upx -o upx-arm64-unpacked
    qemu-aarch64 ./upx-arm64-unpacked --version
    # ...same for more architectures
