hardened_malloc binary

Warning

The libstdc++ and libgcc packages or their equivalents should be installed. Otherwise, you may break your system by trying to preload it globally.

This is a simple containerized build tool that builds the very latest hardened_malloc from Git.

We build this weekly using GitHub Actions.

3 different buildroots are used. Alpine for musl-based systems, Debian for most glibc-based systems and RHEL for Fedora-based systems.

There is a container artifact to build this, or you can use podman-build.1 to build the container. Replace DISTRO with either alpine, debian, or rhel:

mkdir out
podman run -v ./out:/out ghcr.io/charles8191/hardened_malloc/artifact:DISTRO

Demo

Replace DISTRO with either alpine, debian, or rhel.

Charles and this project is not affilated with GrapheneOS in any way, shape or form.
