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 not fully supported by this patch, matching the behavior of Windows.
-- v67: ws2_32/tests: Add test for AF_UNIX sockets. server: Fix getsockname() and accept() on AF_UNIX sockets. server: Introduce error when attempting to create a SOCK_DGRAM AF_UNIX socket. server: Allow for deletion of socket files. ws2_32: Add support for AF_UNIX sockets. ws2_32: Add afunix.h header.

This commit additionally modifies wineserver's sock_ioctl to handle the provided pathname by changing directories and then returning after the native call. This is NOT threadsafe, but wineserver is not multithreaded. --- dlls/ntdll/unix/socket.c | 4 + dlls/ws2_32/socket.c | 83 +++++++++++++++++-- dlls/ws2_32/ws2_32_private.h | 13 +++ server/sock.c | 152 ++++++++++++++++++++++++++++++++--- 4 files changed, 238 insertions(+), 14 deletions(-)

This patch still works on master with all tests passing and the software I use it for still works as expected. I think it would be great for this to be merged, but the deletion code not being up to scratch is an understandable barrier. The first version was even worse. However, at the time I did spend a while looking at ways to get deletion working, and this was the least problematic solution I could come up with. I unfortunately can't really do much more than that unless a more specific criticism than "it's ugly" (which, again, I agree with) is levied. A nominally cleaner solution would probably introduce a lot of extra code just for this one special case, which seems undesired based on feedback for a previous patch of mine, so I'm hesitant to even attempt that. If anyone has any ideas, though, I'm all ears.
@zfigura "be considered ready by the submitter" doesn't means a patch is ready.
I think a lot of good MRs are being submitted and left into dust, a system that allow MRs to be aproved by other developers would allow more MRs to be accepted, like for example, a lot of simple stubs are not being merged and someone passing though MRs found out that https://gitlab.winehq.org/wine/wine/-/merge_requests/5522 code was a containing a duplicate of https://gitlab.winehq.org/wine/wine/-/merge_requests/2374 cause the stub was required to run an installer.
My proposed solution is in no way perfect, but it's still far better than right now, where multiple peoples are developing the same code for wine.

I don't understand? Merge requests can already be approved by anyone, regardless of whether they're an assigned reviewer or maintainer or not.
As explained in 5522, 2374 was never accepted because it didn't actually help anything.
Would this be useful without deletion part? And if yes maybe we could get the socket part in if the path/fd part is controversial?

Without support for deletion, creating a Unix domain socket will always leak an on-disk path. This also, I believe, precludes support for having any tests.
Would changing NtDeleteFile implementation to not go through whole open/close be better? as a side note - does windows even allow CreateFile with AF_UNIX socket paths anyway?
Would adding additional flag to server's create_file request be ok? (that will only be set by NtDeleteFile and if set will skip open call and will automatically do open/close on server side). Advantage of that is that it won't expose ability to CreateFile("file.sock") outside of wine internals. I'm not sure how stable wineserver's protocol needs to be though.
`CreateFile` can be used to "create" a Unix socket file in the same way that `mknod` with `S_IFSOCK` "creates" a Unix socket file. It's a file that exists and presents as a socket, but you can't really do anything with it. On Windows, they're reparse points tagged with `IO_REPARSE_TAG_AF_UNIX`. I don't understand reparse points very well at all yet, but from a cursory reading of Microsoft's documentation, it's likely that there are edge cases with Unix socket files that this MR might need to cover.
To me, adding a flag for a single function doesn't seem like a better solution than the one currently implemented in this MR.

@zfigura I would appreciate it if the "didn't actually help anything" concerns regarding my patches were made in the MR containing them. That would be so that I could have the opportunity to make improvements to them in response to your feedback.

Sure. (Of course, I wasn't the one to make that comment about 2374, and I only commented on 5522 in an attempt to explain the rejection from other contributors.)

I do agree that the file deletion code is a bit hacky, but a lot of the file handling code in wineserver depends on having a valid file descriptor, and we can't `open()` the socket file. This was the simplest way I could find to make socket file deletion work.
A year has now passed. Is it possible that this topic has been solved better in wine in the meantime ?
To see how complete this merge request is, I synchronized the status with git master (https://gitlab.winehq.org/rhabacker/wine/-/commits/afunix), which worked quite well, and used it to build wine from the git master branch. The included tests for ws2_32 ran without any problems, as did the test binaries available at https://bugs.winehq.org/show_bug.cgi?id=52568.
Is it possible to merge this changes ?

Well, everything stalled, last time I tried to push for it to get merged, nothing happened.
Maybe making smaller separate MRs would make the merging process easier?
FYI [nbdkit](https://gitlab.com/nbdkit/nbdkit) is another application which can usefully use AF_UNIX sockets on Windows.
Unfortunately, last time I tried to write tests for Unix sockets, I started triggering kernel panics in Windows. Maybe the situation has improved since then?
It has been improved. As part of the provision of AF_UNIX support for DBus on Windows https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/391 there are corresponding test cases for AF_UNIX, which run without problems on a native Windows.
