1. Account for the fact that go can be already in path. 2. Unset GOROOT in case it is set already. 3. export variables (not sure how it worked for me).

# This script setups everything that's needed to run syzkaller
|
|
# using qemu on known working syzkaller/kernel revisions.
|
|
# Tested on Ubuntu 16.04 and Debian rolling. The script downloads a bunch
|
|
# of stuff, so make sure you have a good internet connection.
|
|
# But first ensure that you have KVM enabled in BIOS and in kernel,
|
|
# otherwise fuzzing will be very slow and lots of things will time out, see:
|
|
# https://help.ubuntu.com/community/KVM/Installation
|
|
# https://www.linux-kvm.org/page/FAQ
|
|
# If everything goes successfully, the script will start syz-manager
|
|
# that will start fuzzing Linux kernel. You should see periodic log lines
|
|
# of the following form:
|
|
# 2018/04/01 10:00:00 VMs 10, executed 50170, cover 42270, crashes 0, repro 0
|
|
# syz-manager web UI contains a summary of crashes:
|
|
# http://localhost:20000
|
|
# You can always abort syz-manager with Ctrl+C and start it again by running
|
|
# the last command of this script.
