Sure, I can do that. Note that pretty much every sendmsg codepath allows other data to take precedence over sk_bound_dev_if: - udpv6_sendmsg: if sin6_scope_id specified on a scoped address - rawv6_sendmsg: if sin6_scope_id specified on a scoped address - l2tp_ip6_sendmsg: if sin6_scope_id specified on a scoped address - ip_cmsg_send: if IP_PKTINFO or IPV6_PKTINFO specified What should I do about those? -EINVAL? Ignore the conflicting data? Leave as is?
