[PATCH 0/1] MR3878: server: Return WSAEOPNOTSUPP on listen() if the socket's type is SOCK_DGRAM

[Ally Sommers (＠dropbear)]

On Windows, `listen()` throws `WSAEOPNOTSUPP` when provided with a `SOCK_DGRAM` socket. Wine currently only throws `WSAEOPNOTSUPP` if the socket is bound; otherwise it throws `WSAEINVAL`. This patch modifies the `IOCTL_AFD_LISTEN` case in wineserver's `sock_ioctl()` throw `WSAEOPNOTSUPP` if it's passed an unbound `SOCK_DGRAM` socket.

[PATCH 1/1] server: Return WSAEOPNOTSUPP on listen() if the socket's type is SOCK_DGRAM.

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:
