Date: Mon, 20 May 2019 19:57:17 +0100 From: Mike Manning <mmanning@...tta.att-mail.com> To: netdev@...r.kernel.org, dsahern@...il.com Subject: [PATCH net] ipv6: Consider sk_bound_dev_if when binding a raw socket to an address IPv6 does not consider if the socket is bound to a device when binding to an address. The result is that a socket can be bound to eth0 and then bound to the address of eth1. If the device is a VRF, the result is that a socket can only be bound to an address in the default VRF. Resolve by considering the device if sk_bound_dev_if is set.
