[PATCH 0/3] MR1988: ntoskrnl.exe/tests: Don't bind to specific listen port from userspace.
Today, the driver_netio test client binds a new socket to a specific network port. This triggers a firewall alert on Windows 7, and the alert UI window may interfere with user32:msg tests.
Fix this by binding to a dynamically-allocated port instead.

Today, the driver_netio test client uses SO_REUSEADDR to reuse previously used network address and port for its socket. This may trigger a firewall alert on Windows 7, and the alert UI window may interfere with user32:msg tests.
Fix this by removing call to setsockopt([...], SO_REUSEADDR, [...]).

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.

Do I understand correctly that the permissions dialog popup is caused solely by SO_REUSEADDR? If that is the case, did you try to just remove setting this option without doing anything else, does anything break?
I am not fully sure now without more testing, but it is possible this SO_REUSEADDR was only needed to avoid test failures on Wine when closing the socket do not immediately make the port available for listen (unlike Windows). SO_REUSEADDR has completely different semantics between winsock and BSD sockets. Since not so long ago the compatibility on this part has been improved in Wine, we now always set native SO_REUSEADDR on TCP sockets. And test expectedly doesn't break for me in Wine if I just remove SO_REUSEADDR. I didn't test it on Windows (only run on testbot) but I'd hope it will be fine there as well.

No, the actual culprit turned out to be binding to `INADDR_ANY` after more testing. It is not clear that `SO_REUSEADDR` is triggering the firewall. This MR does not prevent the firewall alert dialog. I'm submitting a separate PR for that.
(I actually realized this much earlier, but I have only so much time...)

My original theory was that the firewall dialog was caused by _both_ `SO_REUSEADDR` _and_ binding to a fixed port (perhaps only in well-known or registered range?) I thought not hard-coding ports in tests was a good idea in general, but now that the actual cause of the alert turned out to be different, it's true that the extra complexity introduced by dynamic ports is much harder to justify.
