Types

type Generator

type Generator struct {
	Category string
	// contains filtered or unexported fields
}

func New

func New(category string) *Generator

New creates a new generator for a fuzzer of a given category.

func (*Generator) Clear

func (g *Generator) Clear() error

Clear removes the previous fuzzing sessions data and any previously used binaries.

func (*Generator) DownloadSeedFiles

func (g *Generator) DownloadSeedFiles(storageClient fstorage.FuzzerGCSClient) error

DownloadSeedFiles downloads the seed files stored in Google Storage to be used by afl-fuzz. It places them in config.Generator.FuzzSamples/[category] after cleaning the folder out. It returns an error on failure.

func (*Generator) Start

func (g *Generator) Start(ctx context.Context) error

Start starts up 1 goroutine running a "master" afl-fuzz and n-1 "slave" afl-fuzz processes, where n is specified by config.Generator.NumFuzzProcesses. Output goes to config.Generator.AflOutputPath/[category].

func (*Generator) Stop

func (g *Generator) Stop()

Stop terminates all afl-fuzz processes that were spawned, logging any errors. It also sets some key metrics to 0, so the graphs at mon.skia.org reflect the stoppage.
