- Add sa_family_t typedef for Windows in platform_compat.h
- Add forward declaration of struct ll_queue in ll_queue.h to fix warnings
- Replace arpa/inet.h includes with platform_compat.h in:
tun_linux.c, etcp_connections.c, route_lib.c, route_bgp.c,
utun_instance.c, routing.c, utun.c, packet_dump.h, config_parser.c
- All 22 tests pass on Linux
- Split TUN implementation into platform-specific files:
- tun_if.c: Common code (queues, callbacks, statistics)
- tun_linux.c: Linux TUN/TAP implementation (/dev/net/tun + ioctl)
- tun_windows.c: Windows Wintun implementation (wintun.dll + IP Helper)
- Update tun_if.h with platform abstraction layer:
- tun_platform_init/cleanup/read/write/get_poll_fd
- Platform handles: fd (Linux), WINTUN handles (Windows)
- Windows implementation features:
- Dynamic loading of wintun.dll with graceful error handling
- IP Helper API for IP address and MTU configuration
- HANDLE-based uasync integration
- Clear error message if wintun.dll is not found
- Update build system:
- configure.ac: Detect Windows (mingw/msys/cygwin)
- src/Makefile.am: Conditional compilation of tun_linux/tun_windows
- tests/Makefile.am: Link platform-specific TUN objects
- Add wintun.dll and wintun.h to lib/ directory
- All 22 tests pass on Linux
- Ready for MSYS2 UCRT64 Windows build
