When I test this patchset using IPv4 only socket,
Host1:
#sctp_test -H 0.0.0.0 -P 9000 -l
Host2:
#sctp_test -H 0.0.0.0 -P 9000 -h 192.168.0.19 -p 9000 -s -x 1 -D -T
I got following unexpected thing, IPv6 address be added to the asoc.

+int sctp_asconf_mgmt(struct sctp_sock *sp, struct sctp_sockaddr_entry *addrw)
+{

+ addr->v4.sin_port = htons(sp->ep->base.bind_addr.port);
+
af = sctp_get_af_specific(...);
if (sctp_verify_addr(sk, &to, af->sockaddr_len))
return;

+ else
