[PATCH v34 0/7] MR2786: Add support for AF_UNIX sockets
Windows 10 [received support](https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/) for AF_UNIX sockets in Insider Build 17063. This merge request adds basic support for AF_UNIX sockets to ws2_32 and wineserver. Of particular note is the difficulty in handling `sun_path`. Most of the functions that allow for translating Windows paths to Unix paths are not accessible from ws2_32. I considered the following options: * Pass the Windows path to wineserver and do the conversion there. * This is, as far as I can tell, not possible without major rearchitecting. wineserver does not have functions to translate Windows paths to Unix paths, for obvious reasons. * Obtain the current working directory of the requesting process and temporarily change directories to there. * This only handles relative paths and fails for absolute paths, UNC paths, etc. * Conditionally change directories based on whether the path is relative or not. * This is error-prone and wineserver does not have the requisite functions to do this cleanly. I ultimately decided to pass the translated Unix path to wineserver, which changes directories to `dirname(path)`. It then provides `bind` and `connect` with `basename(path)`. This is not threadsafe, but wineserver is not (currently) multithreaded. Abstract sockets are supported by this patch. -- v34: ws2_32/tests: Add test for AF_UNIX sockets fix. server: Fix getsockname() and accept() on AF_UNIX sockets. server: Introduce error when attempting to connect() to abstract AF_UNIX sockets. server: Allow for deletion of socket files. ws2_32: Add support for AF_UNIX sockets. ntdll/unix: Add support for AF_UNIX sockets to multiple functions. ws2_32: Add afunix.h header. https://gitlab.winehq.org/wine/wine/-/merge_requests/2786

Hi, It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated. The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details: The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=134458 Your paranoid android. === debian11 (32 bit report) === oleaut32: vartest.c:9551: Test failed: VarImp: NULL|0x0, DECIMAL|0x0: expected vt I4 hr 0x0, got vt NULL hr 0x0
