Functions ¶

func ComputeBinaryHash ¶

func ComputeBinaryHash(f *os.File) (string, error)

ComputeBinaryHash generates a cache key using xxHash (fastest non-crypto hash). It samples file content + file size.

func ComputeFullHash ¶

func ComputeFullHash(path string) (string, error)

ComputeFullHash computes a full SHA1 hash of the file. This is slower but provides a cryptographically strong hash.

func FindSymbols ¶

func FindSymbols(symbols []elf.Symbol, target SymbolSearch, filter func(*elf.Symbol) bool) ([]*elf.Symbol, error)

func MatchSymbol ¶

func MatchSymbol(symName string, targetSymbols []SymbolSearch) bool

Types ¶

type Elf ¶

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

func NewElf ¶

func NewElf(ctx context.Context, exe string, root string, isContainer bool) (*Elf, error)

NewElf creates a new Elf instance Returns ErrNotELF if the file is not an ELF Remember to call Close() when done

func (*Elf) CalculateUprobeAddresses ¶

func (p *Elf) CalculateUprobeAddresses(ctx context.Context, symbols []elf.Symbol) []elf.Symbol

CalculateUprobeAddresses calculates the loaded address of a symbol (needed for uprobes)

func (*Elf) Close ¶

func (e *Elf) Close() error

func (*Elf) ContainsAnySymbols ¶

func (p *Elf) ContainsAnySymbols(ctx context.Context, targetSymbols []SymbolSearch, typ ...elf.SectionType) (bool, error)

func (*Elf) Elf ¶

func (p *Elf) Elf(ctx context.Context) (*elf.File, error)

func (*Elf) GetSections ¶

func (p *Elf) GetSections(ctx context.Context) []*elf.Section

func (*Elf) Hash ¶

func (e *Elf) Hash(ctx context.Context) (string, error)

func (*Elf) Ldd ¶

func (p *Elf) Ldd(ctx context.Context) ([]string, error)

func (*Elf) Mtime ¶

func (e *Elf) Mtime() time.Time

func (*Elf) Path ¶

func (e *Elf) Path() string

func (*Elf) SearchString ¶

func (e *Elf) SearchString(searchStr string, strategy MatchStrategy) (string, error)

func (*Elf) SearchSymbols ¶

func (p *Elf) SearchSymbols(ctx context.Context, targets []SymbolSearch, sectionTypes ...elf.SectionType) ([]elf.Symbol, error)

type MatchStrategy ¶

type MatchStrategy int

enum for symbol match strategy

const (
	MatchStrategyExact MatchStrategy = iota
	MatchStrategyPrefix
	MatchStrategySuffix
	MatchStrategyContains
)

type SymbolSearch ¶

type SymbolSearch struct {
	Name string
	MatchStrategy
}

func (*SymbolSearch) Bytes ¶

func (s *SymbolSearch) Bytes() []byte
