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.

Host1:
$sctp_test -H 0.0.0.0 -P 9000 -l

Host2:
$ifconfig eth2
eth2      Link encap:Ethernet  HWaddr 52:54:00:70:99:3D 
          inet addr:192.168.1.21  Bcast:192.168.1.255  Mask:255.255.255.0

$ifdown eth2
$sctp_test -H 0.0.0.0 -P 9000 -h 192.168.0.19 -p 9000 -s -x 1 -D -T&
$ifup eth1

and tcpdump and eth1

You may need some thing like this:

[PATCH 3/6] sctp: Add Auto-ASCONF support (core).

+int sctp_asconf_mgmt(struct sctp_sock *sp, struct sctp_sockaddr_entry *addrw)
+{
+    struct sock *sk = sctp_opt2sk(sp);
+    union sctp_addr *addr;
+
+    /* It is safe to write port space in caller. */
+    addr = &addrw->a;
+    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;

+    if (addrw->state == SCTP_ADDR_NEW)
+        return sctp_send_asconf_add_ip(sk, (struct sockaddr *)addr, 1);
+    else
+        return sctp_send_asconf_del_ip(sk, (struct sockaddr *)addr, 1);
+}
