[PATCH v3 0/7] MR1111: winsock: Always use Unix SO_REUSEADDR on TCP sockets.
Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=50955 The problem which this patchset aims to solve is (sometimes) huge timeout on TCP listening port availability on Linux after the listening socket was closed one or another way. By default, the listening port will also be blocked for the whole time accepted socket waits through lengthy timeouts (sometimes; most surely when the listening process with an active connection was force killed, but not limited to this condition). BSD SO_REUSEADDR socket option is aimed mainly to avoid that extra wait on binding already closed listening socket address. From [1]: "Indicates that the rules used in validating addresses supplied in a bind(2) call should allow reuse of local addresses. For AF_INET sockets this means that a socket may bind, except when there is an active listening socket bound to the address.". Unix SO_REUSEADDR does not really allow reusing address in the Winsock sense. It will just allow to ditch the timeout (which is always the case on Windows without any specific options). Unfortunately it is not the only effect of the option. It still won't allow listening on the address simultaneously (unlike Winsock SO_REUSEADDR which allows simultaneous listening), or binding to an address which is being listened. But it will allow to bind different sockets for the same address which is not the Winsock behaviour when Winsock SO_REUSEADDR is set. So the patchset enables SO_REUSEADDR on every TCP socket and introduces the bound address tracking which will allow to return an error from bind() when needed. Not related to this patchset, but Winsock SO_REUSEADDR is somewhat closer to BSD SO_REUSEPORT, although is different in a way that _REUSEPORT will load balance connections between listeners while with Winsock _REUSEADDR the connections will always go to the first listener. I hope that the bound addresses tracking introduced in these patches may be reused in the future. E. g., maybe it might be helpful on the way of implementing the todos introduced by my extended tests (those todos are not related to this patchset and exist both with and without it). 1. https://man7.org/linux/man-pages/man7/socket.7.html -- v3: ws2_32/tests: Also test bind to any together with loopback in a different order. server: Set Unix SO_REUSEADDR on all the TCP sockets. server: Track SO_REUSEADDR value. ntdll: Move SO_REUSEADDR handling to server. ws2_32/tests: Also test TCP6 in test_so_reuseaddr(). ws2_32/tests: Add tests for reusing address without SO_REUSEADDR. https://gitlab.winehq.org/wine/wine/-/merge_requests/1111

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.

It turns out it is breaking httpapi tests, Testbot failures are not random. I additionally tested now that binding to any address after loopback behaves the same way as in reverse order (for which there is a test already): it currently allows even more on Windows (listen too) than we do. So the change introduced by this patch is not wrong, although httpapi currently relies on the old behaviour in this aspect. I think it can be fixed in httpapi by using SO_EXCLUSIVEADDRUSE socket option: I tested that using it even on the second socket only (without setting on the first bound socket), in particular, denies binding to any addr once specific address is already bound. This option should be implemented in Winsock first. My suggestion for now is to add todo to the test and follow up with SO_EXCLUSIVEADDRUSE implementation in winsock and using that in http.sys. I think it should be doable for sockets with SO_EXCLUSIVEADDRUSE on top of the bound address tracking introduced in this patchset. Just doing this at once will further complicate already long and not quite trivial patch from here, and the patch series is not too short already. Meanwhile this can't be done before the address tracking logic is in place. v3: - Add test with binding loopback addr before any addr; - Add todo_wine to failing httpapi tests. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1111#note_12268
