Thanks for the log, the main part:
trace:winsock:WSASocketW af=2 type=1 protocol=6 protocol_info=(nil)
trace:winsock:WSASocketW created 03d8
trace:winsock:WS_setsockopt (socket 03d8, level IPPROTO_IPV6, name
IPV6_V6ONLY, optval 0xb65d788 (0), optlen 4)
trace:winsock:WS_setsockopt Setting socket error, 10042
warn:winsock:wsaErrno errno 92, (Protocol not available).
trace:winsock:WS_shutdown socket 03d8, how 0x2, options 0x0
My concerns for the patch is that you are adding what looks like a
workaround. Please rework the patch into the proper case
WS_IPV6_V6ONLY (move the case to after case WS_IPV6_PROTECTION_LEVEL).
Use a shorter description like "If the socket is not bound it will
always succeed.". Is it true that this only happens for IPV4 sockets?
Is it true that this only happens when value = 0?
Please, improve you tests by extending the existing test function
test_ipv6only, tests for both IPv4 and 6 and checking if the value is
really not changed using getsockopt.
