Functions

func CollectUnused

func CollectUnused(desc *ast.Description, target *targets.Target, eh ast.ErrorHandler) ([]ast.Node, error)

func ExtractConsts

func ExtractConsts(desc *ast.Description, target *targets.Target, eh ast.ErrorHandler) map[string]*ConstInfo

func FabricateSyscallConsts

func FabricateSyscallConsts(target *targets.Target, constInfo map[string]*ConstInfo, cf *ConstFile)

FabricateSyscallConsts adds syscall number constants to consts map. Used for test OS to not bother specifying consts for all syscalls.

func FileList

func FileList(desc *ast.Description, OS string, eh ast.ErrorHandler) map[string]Meta

func Fuzz

func Fuzz(data []byte) int

Types

type Const

type Const struct {
	Name string
	Pos  ast.Pos
}

type ConstFile

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

ConstFile serializes/deserializes .const files.

func DeserializeConstFile

func DeserializeConstFile(glob string, eh ast.ErrorHandler) *ConstFile

func NewConstFile

func NewConstFile() *ConstFile

func (*ConstFile) AddArch

func (cf *ConstFile) AddArch(arch string, consts map[string]uint64, undeclared map[string]bool) error

func (*ConstFile) Arch

func (cf *ConstFile) Arch(arch string) map[string]uint64

func (*ConstFile) ExistsAny

func (cf *ConstFile) ExistsAny(constName string) bool

func (*ConstFile) Serialize

func (cf *ConstFile) Serialize() []byte

type ConstInfo

type ConstInfo struct {
	Consts   []*Const
	Includes []string
	Incdirs  []string
	Defines  map[string]string
}

type Meta

type Meta struct {
	Automatic bool // automatically-generated descriptions
	NoExtract bool // do not run syz-extract on the descriptions by default
	Arches    map[string]bool
}

func (Meta) SupportsArch

func (meta Meta) SupportsArch(arch string) bool

type Prog

type Prog struct {
	Resources []*prog.ResourceDesc
	Syscalls  []*prog.Syscall
	Types     []prog.Type
	// Set of unsupported syscalls/flags.
	Unsupported map[string]bool
	// contains filtered or unexported fields
}

Prog is description compilation result.

func Compile

func Compile(desc *ast.Description, consts map[string]uint64, target *targets.Target, eh ast.ErrorHandler) *Prog

Compile compiles sys description.
