What is //go:linkname?

TLDR it's a sneaky hack to get references to other package's symbols without import-ing them. Go 1.23 imposed new restrictions on which symbols are permitted to be //go:linkname-ed to outside of the Go standard library. That made me curious: what's the list of //go:linkname symbols from the standard library?

📚 Some links for further reading

Code to generate the list

package main

import (
	"fmt"
	"io/fs"
	"log"
	"maps"
	"os"
	"os/exec"
	"path/filepath"
	"regexp"
	"slices"
	"strings"
)

const tag = "go1.24.1"

func main() {
	if _, err := os.Stat(".test/go"); err != nil {
		cmd := exec.Command("git", "clone", "https://go.googlesource.com/go", ".test/go")
		cmd.Stdin = os.Stdin
		cmd.Stdout = os.Stdout
		cmd.Stderr = os.Stderr
		log.Printf("$ %v", cmd)
		err := cmd.Run()
		if err != nil {
			log.Fatal(err)
		}
	}

	allLinknames := map[string][]string{}

	goSrcFS := os.DirFS(".test/go/src")
	err := fs.WalkDir(goSrcFS, ".", func(path string, d fs.DirEntry, err error) error {
		if err != nil {
			return err
		}
		if d.IsDir() {
			if slices.Contains([]string{"internal", "testdata", "vendor"}, d.Name()) {
				return fs.SkipDir
			}
			return nil
		}
		if !strings.HasSuffix(d.Name(), ".go") {
			return nil
		}
		packagePath := filepath.ToSlash(filepath.Dir(path))
		data, err := fs.ReadFile(goSrcFS, path)
		if err != nil {
			return err
		}
		linknames := regexp.MustCompile(`(?m)^//go:linkname\s+(\w+)(?:\s+([\w\.]+))?$`).FindAllSubmatch(data, -1)
		for _, match := range linknames {
			if len(match) != 3 {
				panic("unexpected match length")
			}
			var remoteName string
			if len(match[2]) != 0 {
				remoteName = string(match[2])
			} else {
				remoteName = packagePath + "." + string(match[1])
			}
			allLinknames[packagePath] = append(allLinknames[packagePath], remoteName)
		}
		return nil
	})
	if err != nil {
		log.Fatal(err)
	}

	for _, packagePath := range slices.Sorted(maps.Keys(allLinknames)) {
		linknames := allLinknames[packagePath]
		fmt.Printf("package %s\n", packagePath)
		for _, linkname := range linknames {
			// localName := linkname[strings.LastIndex(linkname, ".")+1:]
			fmt.Printf("%s\n", linkname)
		}
		fmt.Printf("\n")
	}
}

The list

This is an overestimate of the linknames available in the Go standard library. Some of the //go:linkname directives are gated behind //go:build directives for specific operating systems or features. Some of them are false-positives. Some are duplicates. I may try to incrementally clean the list a bit but there's just so many items! 😅

💡 Tip: Use Ctrl+F to search through this list. Then search for the <package>.<name> name part of the directive on https://cs.opensource.google/go/go.
