net: only enable broadcast on sockets which support it Only enable broadcast on SOCK_DGRAM and SOCK_RAW sockets, SOCK_STREAM and others don't support it. Don't enable SO_BROADCAST on UNIX domain sockets as they don't support it. This caused failures on WSL which strictly checks setsockopt calls unlike other OSes which often silently ignore bad options. Also return error for setsockopt call for SO_BROADCAST on Windows matching all other platforms but for IPv4 only as it's not supported on IPv6 as per: https://docs.microsoft.com/en-us/windows/win32/winsock/socket-options Fixes #38954 Change-Id: I0503fd1ce96102b17121af548b66b3e9c2bb80d3 Reviewed-on: https://go-review.googlesource.com/c/go/+/232807 Run-TryBot: Ian Lance Taylor <iant@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>
