| | | | | | | | | | | | | | | | | Some users are seeing errors like this after rebooting from Windows Update: 2021-01-28 18:39:45.220197: [TUN] Creating Wintun interface 2021-01-28 18:39:49.420116: [TUN] [Wintun] CreateAdapter: Creating adapter 2021-01-28 18:39:53.704007: [TUN] [Wintun] OpenDeviceObject: Failed to connect to adapter: The system cannot find the path specified. (Code 0x00000003) 2021-01-28 18:39:53.704007: [TUN] [Wintun] WintunStartSession: Failed to open adapter device object 2021-01-28 18:39:54.097037: [TUN] Unable to create Wintun interface: Error starting session: The system cannot find the path specified. It appears that creation of the device object file might happen asynchronously, so this commit polls for it. Reported-by: Artem Kuroptev <artem@kuroptev.com> Signed-off-by: Jason A.

* api: use custom devpkey for poolJason A. Donenfeld2021-01-301-2/+28
| | | | | | | | | | It seems like the friendly name is still getting reset sometimes. Rather than swimming upstream, it turns out we can just use a custom devpkey that, according to msdn, is respected. https://docs.microsoft.com/en-us/windows-hardware/drivers/install/creating-custom-device-properties Signed-off-by: Jason A.

* api: retry on ERROR_TRANSACTION_NOT_ACTIVE when disabling dead GW detectSimon Rozman2020-11-171-18/+27
| | | | | | | | There seems to be a race in the TCP/IP adapter registry key. Sometimes, the adapter TCP/IP key is created, but setting the value EnableDeadGWDetect fails with ERROR_TRANSACTION_NOT_ACTIVE. Signed-off-by: Simon Rozman <simon@rozman.si>

* api: do not call UpdateDriverForPlugAndPlayDevicesWJason A. Donenfeld2020-11-091-10/+2
| | | | | | | This seems to reset a number of device properties, and our update flow seems to update old adapters without needing to call this. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
* api: take pool mutex when deletingJason A. Donenfeld2020-11-091-1/+10
| | | | | | | This prevents us from racing with driver deletion. Mutexes are recursive, so we shouldn't deadlock if called from Enum. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* api: rename GetVersion to GetRunningDriverVersionJason A. Donenfeld2020-11-041-2/+2
| | | | | | | This makes our intentions a lot more clear, and in case we ever add other version functions, makes the forward path simpler. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* wintun: extract inf driverver at compile time into C headerJason A. Donenfeld2020-11-031-111/+4
| | | | | | | | | | | | This requires us to make some insane conversions between INF date, JavaScript time, and finally Windows file time. The point is to mimic SystemTimeToFileTime, which is what SpInf.dll's pSetupStringToDriverDate does on the YYYY-MM-DD from the INF. The result is that we no longer have to parse an ancient text format in C at runtime. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* api: remove guid getterJason A. Donenfeld2020-11-031-6/+0
| | | | | | | | | The iphlpapi takes both LUIDs and GUIDs but prefers LUIDs, so exposing the NET_LUID makes sense. However, we were previously exposing the configuration GUID, rather than the net GUID, which is confusing, so just make it all go away. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

| | | | | | | | | | | | | | It'd be nicer to do this via if (is_defined(HAVE_WHATEVER)) But MSVC won't work with the linux kernel macros for this. Ongoing research. Nevertheless, this makes most of the program always pass through the compiler's type checker, only to have dead code removed later. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
