buildinfo

README

This code is a copied and slightly modified subset of go/src/debug/buildinfo.

It contains logic for parsing Go binary files for the purpose of extracting module dependency and symbol table information.

Logic added by vulncheck is located in files with "additions_" prefix.

Within the originally named files, changed or added logic is annotated with a comment starting with "Addition:".

Variables

var ErrNoSymbols = errors.New("no symbol section")

ErrNoSymbols represents non-existence of symbol table in binaries supported by buildinfo.

Types

type Symbol

type Symbol struct {
	Pkg  string `json:"pkg,omitempty"`
	Name string `json:"name,omitempty"`
}

func ExtractPackagesAndSymbols

func ExtractPackagesAndSymbols(bin io.ReaderAt) ([]*packages.Module, []Symbol, *debug.BuildInfo, error)

ExtractPackagesAndSymbols extracts symbols, packages, modules from bin as well as bin's metadata.

If the symbol table is not available, such as in the case of stripped binaries, returns module and binary info but without the symbol info.
