Functions ¶

func ExecprogCmd ¶

func ExecprogCmd(execprog, executor, OS, arch, sandbox string, repeat, threaded, collide bool,
	procs, faultCall, faultNth int, progFile string) string

func FuzzerCmd ¶

func FuzzerCmd(fuzzer, executor, name, OS, arch, fwdAddr, sandbox string, procs, verbosity int,
	cover, debug, test, runtest bool) string

func SetConfigImage ¶

func SetConfigImage(cfg *mgrconfig.Config, imageDir string) error

Types ¶

type CrashError ¶

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)

Test boots numVMs VMs, tests basic kernel operation, and optionally tests the provided reproducer. TestError is returned if there is a problem with kernel/image (crash, reboot loop, etc). CrashError is returned if the reproducer crashes kernel.

type TestError ¶

type TestError struct {
	Boot   bool // says if the error happened during booting or during instance testing
	Title  string
	Output []byte
	Report *report.Report
}

func (*TestError) Error ¶

func (err *TestError) Error() string
