Support for the unix socket has existed both in BSD and Linux for the longest time, but not on Windows. Since Windows 10 build 17063 [1], the native support for the unix socket has came to Windows. Starting this build, two Win32 processes can use the AF_UNIX address family over Winsock API to communicate with each other.
Introduce a new build time config option CONFIG_AF_UNIX when the build host has such a capability, and a run-time check afunix_available() for Windows host in the QEMU sockets util codes. [1] https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/ Changes in v2: - move #include <afunix.h> to os-win32.h - define WIN_BUILD_AF_UNIX only when CONFIG_WIN32 - drop #include <afunix.h> as it is now already included in osdep.h - new patch: tests/unit: Update test-io-channel-socket.c for Windows Bin Meng (6): util/qemu-sockets: Replace the call to close a socket with closesocket() util/oslib-win32: Add a helper to get the Windows version qga/commands-win32: Use os_get_win_version() util/qemu-sockets: Enable unix socket support on Windows chardev/char-socket: Update AF_UNIX for Windows tests/unit: Update test-io-channel-socket.c for Windows meson.build | 6 ++++ include/sysemu/os-win32.h | 6 ++++ chardev/char-socket.c | 4 ++- qga/commands-win32.c | 27 +--------------- tests/unit/test-io-channel-socket.c | 16 ++++++++-- util/oslib-win32.c | 15 +++++++++ util/qemu-sockets.c | 49 +++++++++++++++++++++++------ 7 files changed, 85 insertions(+), 38 deletions(-) -- 2.34.1
