* wintun: Revise interface creation waitSimon Rozman2019-03-073-59/+106
| | | | | | | | | | | | | | | | | | | | 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>

* Simplify reading NetCfgInstanceId from registrySimon Rozman2019-03-041-8/+2
| | | | | | | | 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>
