* api: header: silence MSVC warnings for MSVC onlySimon Rozman2021-12-031-3/+7
| | | | | | | MinGW ignores unknown `#pragma warning` lines, but displays a warning nevertheless. Signed-off-by: Simon Rozman <simon@rozman.si>

* api: make .h filenames lowercase for building with MinGW on LinuxSimon Rozman2021-03-161-2/+2
| | | | | | | | MinGW supplies all Windows header files using lowercase filenames. This makes some of the #include lines in wintun.h fail to resolve the .h files correctly on a case-sensitive filesystem. Signed-off-by: Simon Rozman <simon@rozman.si>

* api: allow header to be mitJason A. Donenfeld2020-11-271-1/+1
| | | | | | | This doesn't change much, but it does make it mildly more convenient plop this into mixed-use codebases. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

* api: remove WintunOpenAdapterDeviceObjectJason A. Donenfeld2020-11-051-12/+0
| | | | | | | 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>
* api: rearrange wintun.h to have better grouping and improve docsJason A. Donenfeld2020-11-051-26/+27

* api: rename GetVersion to GetRunningDriverVersionJason A. Donenfeld2020-11-041-1/+1
| | | | | | | 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>
* api: translate NTSTATUS to Win32 error codesSimon Rozman2020-11-041-2/+1

* api: remove guid getterJason A. Donenfeld2020-11-031-9/+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>

* api: depretiate WintunIsPacketAvailable()Simon Rozman2020-10-311-9/+0
| | | | | | | Spinning on the WintunReceivePacket() while it returns ERROR_NO_MORE_ITEMS achieves the same. Signed-off-by: Simon Rozman <simon@rozman.si>
* api: upgrade ring managementSimon Rozman2020-10-311-45/+49
| | | | | | | | | - Return pointer to ring buffer with packet data allowing clients to read/write directly. This eliminates one memcpy(). - Make sending/receiving packets thread-safe. Signed-off-by: Simon Rozman <simon@rozman.si>
* api: allow wintun.h use in C++Simon Rozman2020-10-301-0/+8
| | | | Signed-off-by: Simon Rozman <simon@rozman.si>
* api: add ring managementSimon Rozman2020-10-301-0/+123
| | | | | | | | Rather than every client reinvent the art of using the Wintun and its ring buffers, we offer helper structs and functions to unify and simplify Wintun usage. Signed-off-by: Simon Rozman <simon@rozman.si>
* api: connect rundll32 child with parent using stdout and stderrSimon Rozman2020-10-301-1/+3
| | | | | | | | | | | | | | | | | The WintunCreateAdapter()+CreateAdapter() and WintunDeleteAdapter()+ DeleteAdapter() communicate using Unicode anonymous pipes now. This allows the WintunCreateAdapter() to exactly determine the adapter CreateAdapter() just created by its GUID rather than its name - avoiding the possible ambiguity caused by same-adapter-name ordinal suffixes. This also allows exact retrieval of the result code and pending reboot flag from the rundll32 child process. Furthermore, CreateAdapter() and DeleteAdapter() are now available in _DEBUG for all platforms to allow testing. It took a #pragma comment( linker, "/EXPORT") trick to stop compiler from decorating function names and exporting as _CreateAdapter@16() and _DeleteAdapter@16() in x86. Signed-off-by: Simon Rozman <simon@rozman.si>
* api: introduce wintun.hSimon Rozman2020-10-301-0/+211
The SDK header for deployment containing datatype and function declarations for use by C/C++ clients. As we shall not distribute MSVC wintun.lib files, making clients need to use GetProcAddress(), this file contains function type declarations rather then __declspec(dllimport) function declarations.
