tun: openbsd: check for interface already being up
...
In some cases, we operate on an already-up interface, or the user brings
up the interface before we start monitoring. For those situations, we
should first check if the interface is already up.
This still technically races between the initial check and the start of
the route loop, but fixing that is a bit ugly and probably not worth it
at the moment.

tun: use netpoll instead of rwcancel

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")
}

tun: only call .Fd() once
...
Doing so tends to make the tunnel blocking, so we only retrieve it once
before we call SetNonblock, and then cache the result.
