## Installation

Read [Qemu API](qemu/README.md).

### Generate images

    $ cd $GOPATH/src/github.com/jollheef/out-of-tree/tools/qemu-debian-img/
    $ docker run --privileged -v $(pwd):/shared -e IMAGE=/shared/ubuntu1404.img -e RELEASE=trusty -t gen-ubuntu1804-image
    $ docker run --privileged -v $(pwd):/shared -e IMAGE=/shared/ubuntu1604.img -e RELEASE=xenial -t gen-ubuntu1804-image

### Generate kernels

    cd $GOPATH/src/github.com/jollheef/out-of-tree/tools/kernel-factory
    ./bootstrap.sh # more than 6-8 hours for all kernels

### "I just want to see how it works"

If you already have Go, Qemu and Docker installed, there's cross-platform installation checklist:

    $ go get github.com/jollheef/out-of-tree
    $ cd $GOPATH/src/github.com/jollheef/out-of-tree/tools/qemu-debian-img/
    $ ./bootstrap.sh
    $ docker run --privileged -v $(pwd):/shared -e IMAGE=/shared/ubuntu1604.img -e RELEASE=xenial -t gen-ubuntu1804-image
    $ cd ../kernel-factory
    $ rm -rf {Debian,CentOS,Ubuntu/{14.04,18.04}} # speed up :)
    $ ./bootstrap.sh
    $ # wait several hours...
    $ export OUT_OF_TREE_KCFG=$GOPATH/src/github.com/jollheef/out-of-tree/tools/kernel-factory/output/kernels.toml
    $ cd ../../examples/kernel-exploit
    $ # test kernel exploit
    $ out-of-tree pew
    $ cd ../kernel-module
    $ # test kernel module
    $ out-of-tree pew

## Examples

Run by absolute path

    $ out-of-tree --path /path/to/exploit/directory pew

Test only with one kernel:

    $ out-of-tree pew --kernel='Ubuntu:4.10.0-30-generic'

Test binary module/exploit with implicit defined test ($BINARY_test)

    $ out-of-tree pew --binary /path/to/exploit

Test binary module/exploit with explicit defined test

    $ out-of-tree pew --binary /path/to/exploit --test /path/to/exploit_test

Guess work kernels:

    $ out-of-tree pew --guess

Use custom kernels config

    $ out-of-tree --kernels /path/to/kernels.toml pew
