| Subject: | [PATCH] CAN_DISABLE_V6ONLY crashes under dragonfly |
Hello,
CAN_DISABLE_V6ONLY crashes with "Cannot setsockopt() - Operation not supported" under DragonFly BSD.
Excerpt from "man ip6" from dragonfly:
Show quoted text
>IPV6_V6ONLY int *
> Get or set whether only IPv6 connections can be made to this
> socket. For wildcard sockets, this can restrict connections to
> IPv6 only. With DragonFly, the socket option cannot be set to 0
> (which will result in returning EOPNOTSUPP).
All tests pass when attached patch is applied.
