2019-04-19setupapi: Fix struct size mismatchesSimon Rozman
Signed-off-by: Simon Rozman <simon@rozman.si>
2019-04-19setupapi: actually fix padding by rounding up to sizeof(void*)Jason A. Donenfeld
2019-04-19tun: darwin: write routeSocket variable in helperJason A. Donenfeld
Otherwise the race detector "complains".
2019-04-18setupapi: Revise DrvInfoDetailData struct size calculationSimon Rozman
Go adds trailing padding to DrvInfoDetailData struct in GOARCH=386 which confuses SetupAPI expecting exactly sizeof(SP_DRVINFO_DETAIL_DATA). Signed-off-by: Simon Rozman <simon@rozman.si>

2019-03-21tun: windows: add dummy overlapped events backJason A. Donenfeld
These seem basically wrong to me, but we get crashes without them.

2019-03-07wintun: Revise interface creation waitSimon Rozman
DIF_INSTALLDEVICE returns almost immediately, while the device installation continues in the background. It might take a while, before all registry keys and values are populated. Previously, wireguard-go waited for HKLM\SYSTEM\CurrentControlSet\ Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\<id> registry key only. Followed by a SetInterfaceName() method of Wintun struct which tried to access HKLM\SYSTEM\CurrentControlSet\Control\Network\ {4D36E972-E325-11CE-BFC1-08002BE10318}\<id>\Connection registry key might not be available yet. This commit loops until both registry keys are available before returning from CreateInterface() function. Signed-off-by: Simon Rozman <simon@rozman.si>

2019-03-04Simplify reading NetCfgInstanceId from registrySimon Rozman
As querying non-existing registry value and reading non-existing registry string value both return ERROR_FILE_NOT_FOUND, we can use later only. Signed-off-by: Simon Rozman <simon@rozman.si>

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") }
