2019-02-27tun: linux: netpoll is broken for tun's epollJason A. Donenfeld
So this mostly reverts the switch to Sysconn for Linux. Issue: https://github.com/golang/go/issues/30426
2019-02-27tun: linux: netlink sock needs cleaning up but file will be gc'dJason A. Donenfeld
2019-02-27tun: use netpoll instead of rwcancelJason A. Donenfeld
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") }

2019-02-22wintun: Read/write packet size from/to exchange buffer directlySimon Rozman
Driver <-> user-space communication is local and using native endian. Signed-off-by: Simon Rozman <simon@rozman.si>
2019-02-22wintun: Make two-step slicing a one stepSimon Rozman
Stop relying to Go compiler optimizations and calculate the end offset directly. Signed-off-by: Simon Rozman <simon@rozman.si>

2019-02-20wintun: Add TUN device lockingSimon Rozman
In case reading from TUN device detected TUN device was closed, it closed the file handle and set tunFile to nil. The tunFile is automatically reopened on retry, but... If another packet comes in the WireGuard calls Write() method. With tunFile set to nil, this will cause access violation. Therefore, locking was introduced.

2019-02-20wintun: Move exchange buffer in separate struct on heapSimon Rozman
This allows buffer alignment and keeps it together with its meta-data. Furthermore, the write buffer has been reduced - as long as we flush after _every_ write, we don't need a 1MiB write buffer. Signed-off-by: Simon Rozman <simon@rozman.si>

2019-02-08wintun: Check for user close in read loop regardless the loadSimon Rozman
Do the WaitForSingleObject() always to provide high-load responsiveness. Reorder events so TUN_SIGNAL_CLOSE has priority over TUN_SIGNAL_DATA_AVAIL, to provide high-load responsiveness at all. Signed-off-by: Simon Rozman <simon@rozman.si>
