Regarding to the code snippet in net_util_md.c, the reason I check for ENOPROTOOPT is to enable SO_REUSEPORT in the situation that the feature is supported but something else happens during setsocksopts call. I totally agree this is much less safer than just disable the feature whenever the setsockopts returns error. Alan, please let me know what your take on this is. I can quick change it if you both think it is more appropriate to remove the ENOPROTOOPT check.
