* tun: use netpoll instead of rwcancelJason A. Donenfeld2019-02-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new sysconn function of Go 1.12 makes this possible: package main import "log" import "os" import "unsafe" import "time" import "syscall" import "sync" import "golang.org/x/sys/unix" func main() { fd, err := os.OpenFile("/dev/net/tun", os.O_RDWR, 0) if err != nil { log.Fatal(err) } var ifr [unix.IFNAMSIZ + 64]byte copy(ifr[:], []byte("cheese")) *(*uint16)(unsafe.Pointer(&ifr[unix.IFNAMSIZ])) = unix.IFF_TUN var errno syscall.Errno s, _ := fd.SyscallConn() s.Control(func(fd uintptr) { _, _, errno = unix.Syscall( unix.SYS_IOCTL, fd, uintptr(unix.TUNSETIFF), uintptr(unsafe.Pointer(&ifr[0])), ) }) if errno != 0 { log.Fatal(errno) } b := [4]byte{} wait := sync.WaitGroup{} wait.Add(1) go func() { _, err := fd.Read(b[:]) log.Print("Read errored: ", err) wait.Done() }() time.Sleep(time.Second) log.Print("Closing") err = fd.Close() if err != nil { log.Print("Close errored: " , err) } wait.Wait() log.Print("Exiting") }
