2020-11-09api: relax IsPoolMember estimationJason A. Donenfeld1-27/+14
Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-11-09api: do not call UpdateDriverForPlugAndPlayDevicesWJason A. Donenfeld2-13/+5
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>
2020-11-09api: take pool mutex when deletingJason A. Donenfeld1-1/+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>
2020-11-09api: account for adapter disappearing during deletionJason A. Donenfeld1-4/+6
This makes the race less fatal. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-11-07api: manipulate process token if thread token didn't require impersonationJason A. Donenfeld1-8/+11
Otherwise rundll32.exe fails if we're already SYSTEM. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-11-07api: fix Function and Prefix logging orderSimon Rozman1-1/+1
Signed-off-by: Simon Rozman <simon@rozman.si>
2020-11-07api: fix LastError overrideSimon Rozman1-3/+4
The LastError was overridden by the stdout reader thread exit code masking the true reason why ExecuteRunDll32() failed and even worse: as the thread exited gracefully, the true reason was overridden by ERROR_SUCCESS and returning TRUE (success). Signed-off-by: Simon Rozman <simon@rozman.si>

2020-11-05api: include arm64 in amd64Jason A. Donenfeld3-3/+4
ARM64 will still run AMD64 apps. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-11-05api: remove WintunOpenAdapterDeviceObjectJason A. Donenfeld7-37/+14
Discourage use of kernel interface, which gives us more flexibility if we ever want to change it. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2020-11-05api: rename WintunGetAdapter to WintunOpenAdapterJason A. Donenfeld5-22/+22
"Create" and "Open" natural names for these. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-11-05api: rename ReceiveRelease to ReleaseReceivePacketJason A. Donenfeld5-17/+16
This makes the API parallel: Wintun*Allocate*SendPacket -> WintunSendPacket WintunReceivePacket -> Wintun*Release*ReceivePacket Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2020-11-04api: upgrade nci.lib and wintun-inf.h buildingSimon Rozman3-15/+15
The additional build steps performed are now attached to the build process using BeforeTargets/AfterTargets. Signed-off-by: Simon Rozman <simon@rozman.si>
2020-11-04api: rename GetVersion to GetRunningDriverVersionJason A. Donenfeld5-8/+9
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>

2020-11-03wintun: upset everybody by doing multiplication via string concatenationJason A. Donenfeld1-1/+1
Because we can. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
2020-11-03wintun: extract inf driverver at compile time into C headerJason A. Donenfeld4-111/+28
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>

2020-11-03api: remove guid getterJason A. Donenfeld4-21/+2
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>

2020-11-03api: conditionalize quasi expensive prelinkeventJason A. Donenfeld1-1/+1
It would be better to do this only if either nci.def or nci.h are newer than nci.lib, but who knows if msbuild is expressive enough for this. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
