BREAKING CHANGE: kernel definition in the configuration files has switched
from
[[targets]]
distro = { id = "Ubuntu", release = "18.04" }
release_mask = ".*"
to
[[targets]]
distro = { id = "Ubuntu", release = "18.04" }
kernel = { regex = ".*" }

out-of-tree
out-of-tree is the kernel {module, exploit} development tool.
out-of-tree was created to reduce the complexity of the environment for developing, testing and debugging Linux kernel exploits and out-of-tree kernel modules (hence the name "out-of-tree").
Installation
GNU/Linux (with Nix)
sudo apt install podman || sudo dnf install podman
curl -L https://nixos.org/nix/install | sh
mkdir -p ~/.config/nix
echo "experimental-features = nix-command flakes" >> ~/.config/nix/nix.conf
# stable
nix profile install nixpkgs#out-of-tree
# latest
nix profile install git+https://code.dumpstack.io/tools/out-of-tree
macOS
Note: case-sensitive FS is required for the ~/.out-of-tree directory.
$ brew install podman
$ podman machine stop || true
$ podman machine rm || true
$ podman machine init --cpus=4 --memory=4096 -v $HOME:$HOME
$ podman machine start
$ brew tap out-of-tree/repo
$ brew install out-of-tree
Read documentation for further info.
Examples
Generate all Ubuntu 22.04 kernels:
$ out-of-tree kernel genall --distro=Ubuntu --ver=22.04
Run tests based on .out-of-tree.toml definitions:
$ out-of-tree pew
Test with a specific kernel:
$ out-of-tree pew --kernel='Ubuntu:5.4.0-29-generic'
Run debug environment:
$ out-of-tree debug --kernel='Ubuntu:5.4.0-29-generic'
