The rule is to always update them to the full packet size minus UDP/IP
encapsulation for all authenticated packet types.

Jason A. Donenfeld da61947ec3 tun: windows: mitigate infinite loop in Flush() 
It's possible that for whatever reason, we keep returning EOF, resulting
in repeated close/open/write operations, except with empty packets.

The only time we're trying to counteract the race condition is when
we're creating a driver. When we're simply looking up all drivers, it
doesn't make sense to retry.

Jason A. Donenfeld bb42ec7d18 tun: freebsd: work around numerous kernel panics on shutdown 
There are numerous race conditions. But even this will crash it:

while true; do ifconfig tun0 create; ifconfig tun0 destroy; done

It seems like LLv6 is related, which we're not using anyway, so
explicitly disable it on the interface.

Pipes can be arranged like this, so that's fine. We also apply a strict
SDDL that can't be inherited and only gives access to local system.

Jason A. Donenfeld 971be13e77 tun: linux: netlink sock needs cleaning up but file will be gc'd 2019-02-27 04:11:41 +01:00
Jason A. Donenfeld 366cbd11a4 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")
}
