Types

type Config

type Config struct {
	// Instance name (used for identification and as GCE instance prefix).
	Name string `json:"name"`
	// Target OS/arch, e.g. "linux/arm64" or "linux/amd64/386" (amd64 OS with 386 test process).
	Target string `json:"target"`
	// TCP address to serve HTTP stats page (e.g. "localhost:50000").
	HTTP string `json:"http"`
	// TCP address to serve RPC for fuzzer processes (optional).
	RPC     string `json:"rpc"`
	Workdir string `json:"workdir"`
	// Directory with kernel object files.
	KernelObj string `json:"kernel_obj"`
	// Kernel source directory (if not set defaults to KernelObj).
	KernelSrc string `json:"kernel_src"`
	// Arbitrary optional tag that is saved along with crash reports (e.g. branch/commit).
	Tag string `json:"tag"`
	// Linux image for VMs.
	Image string `json:"image"`
	// SSH key for the image (may be empty for some VM types).
	SSHKey string `json:"sshkey"`
	// SSH user ("root" by default).
	SSHUser string `json:"ssh_user"`

	HubClient string `json:"hub_client"`
	HubAddr   string `json:"hub_addr"`
	HubKey    string `json:"hub_key"`

	// syz-manager will send crash emails to this list of emails using mailx (optional).
	EmailAddrs []string `json:"email_addrs"`

	DashboardClient string `json:"dashboard_client"`
	DashboardAddr   string `json:"dashboard_addr"`
	DashboardKey    string `json:"dashboard_key"`

	// Path to syzkaller checkout (syz-manager will look for binaries in bin subdir).
	Syzkaller string `json:"syzkaller"`
	// Number of parallel processes inside of every VM.
	Procs int `json:"procs"`

	// Type of sandbox to use during fuzzing:
	// "none": don't do anything special (has false positives, e.g. due to killing init), default
	// "setuid": impersonate into user nobody (65534)
	// "namespace": create a new namespace for fuzzer using CLONE_NEWNS/CLONE_NEWNET/CLONE_NEWPID/etc,
	//	requires building kernel with CONFIG_NAMESPACES, CONFIG_UTS_NS, CONFIG_USER_NS,
	//	CONFIG_PID_NS and CONFIG_NET_NS.
	Sandbox string `json:"sandbox"`

	// Use KCOV coverage (default: true).
	Cover bool `json:"cover"`
	// Reproduce, localize and minimize crashers (default: true).
	Reproduce bool `json:"reproduce"`

	EnabledSyscalls  []string `json:"enable_syscalls"`
	DisabledSyscalls []string `json:"disable_syscalls"`
	// Don't save reports matching these regexps, but reboot VM after them,
	// matched against whole report output.
	Suppressions []string `json:"suppressions"`
	// Completely ignore reports matching these regexps (don't save nor reboot),
	// must match the first line of crash message.
	Ignores []string `json:"ignores"`

	// VM type (qemu, gce, android, isolated, etc).
	Type string `json:"type"`
	// VM-type-specific config.
	VM json.RawMessage `json:"vm"`

	// Implementation details beyond this point.
	// Parsed Target:
	TargetOS     string `json:"-"`
	TargetArch   string `json:"-"`
	TargetVMArch string `json:"-"`
	// Syzkaller binaries that we are going to use:
	SyzFuzzerBin   string `json:"-"`
	SyzExecprogBin string `json:"-"`
	SyzExecutorBin string `json:"-"`
