# syz-env is a wrapper around gcr.io/syzkaller/env container,
|
|
# which includes all tools necessary to develop/test syzkaller.
|
|
# It's recommended to create an alias for this script:
|
|
#
|
|
# alias syz-env="$(go env GOPATH)/src/github.com/google/syzkaller/tools/syz-env"
|
|
#
|
|
# Then it can be used to wrap almost any make invocation as:
|
|
#
|
|
# syz-env make format
|
|
# syz-env make presubmit
|
|
# syz-env make extract SOURCEDIR=~/linux
|
|
#
|
|
# Or you may run the shell inside of the container with just syz-env.
|
|
#
|
|
# Note: this way everything runs inside of the container
|
|
# and uses all tools bundled in the container rather than host tools.
|
|
#
|
|
# Note: syz-env assumes a sudo-less Docker is installed, see:
|
|
# https://docs.docker.com/engine/install
|
|
# https://docs.docker.com/engine/install/linux-postinstall
|
|
# (Googlers see go/docker).
