type CrashError struct {
	Report *report.Report
}

func (*CrashError) Error

func (err *CrashError) Error() string

type Env

type Env struct {
	// contains filtered or unexported fields
}

func NewEnv

func NewEnv(cfg *mgrconfig.Config) (*Env, error)

func (*Env) BuildKernel

func (env *Env) BuildKernel(compilerBin, userspaceDir, cmdlineFile, sysctlFile string, kernelConfig []byte) error

func (*Env) BuildSyzkaller

func (env *Env) BuildSyzkaller(repo, commit string) error

func (*Env) Test

func (env *Env) Test(numVMs int, reproSyz, reproOpts, reproC []byte) ([]error, error)

type TestError

type TestError struct {
	Boot   bool // says if the error happened during booting or during instance testing
