* tun: linux: netpoll is broken for tun's epollJason A. Donenfeld2019-02-271-27/+48
| | | | | | So this mostly reverts the switch to Sysconn for Linux. Issue: https://github.com/golang/go/issues/30426
* tun: linux: netlink sock needs cleaning up but file will be gc'dJason A. Donenfeld2019-02-271-4/+2

* tun: use netpoll instead of rwcancelJason A. Donenfeld2019-02-271-41/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: use sysconn instead of .Fd with Go 1.12Jason A. Donenfeld2019-02-271-24/+21

* tun: remove nonblock hack for linuxJason A. Donenfeld2018-12-061-10/+0
| | | | | | This is no longer necessary and actually breaks things Reported-by: Chris Branch <cbranch@cloudflare.com>
* tun: only call .Fd() onceJason A. Donenfeld2018-10-171-15/+17
| | | | | Doing so tends to make the tunnel blocking, so we only retrieve it once before we call SetNonblock, and then cache the result.

* Adopt GOPATHJason A. Donenfeld2018-05-231-1/+1
| | | | | GOPATH is annoying, but the Go community pushing me to adopt it is even more annoying.
