sctp_inet6addr_event deletes 'addr' from 'local_addr_list' when setting netdev down, but it is possible to delete the incorrect entry (match the first one with the same ipaddr, but the different 'ifindex'), if there are some netdevs with the same 'local-link' ipaddr added already. It should delete the entry depending on 'sin6_addr' and 'sin6_scope_id' both. otherwise, the endpoint will call 'sctp_sf_ootb' if it can't find the according association when receives 'heartbeat', and finally will reply 'abort'. For example: 1.when linux startup the entries in local_addr_list: ifindex:35 addr:fe80::40:43ff:fe80:0 (eths0.201) ifindex:36 addr:fe80::40:43ff:fe80:0 (eths0.209) ifindex:37 addr:fe80::40:43ff:fe80:0 (eths0.210) the route table: local fe80::40:43ff:fe80:0 dev eths0.201 local fe80::40:43ff:fe80:0 dev eths0.209 local fe80::40:43ff:fe80:0 dev eths0.210 2.after 'ifconfig eths0.209 down' the entries in local_addr_list: ifindex:36 addr:fe80::40:43ff:fe80:0 (eths0.209) ifindex:37 addr:fe80::40:43ff:fe80:0 (eths0.210) the route table: local fe80::40:43ff:fe80:0 dev eths0.201 local fe80::40:43ff:fe80:0 dev eths0.210 3.asoc not found for src:[fe80::40:43ff:fe80:0]:37381 dst:[:1]:53335 ::1->fe80::40:43ff:fe80:0 HEARTBEAT fe80::40:43ff:fe80:0->::1 ABORT Signed-off-by: Chen Shen <peterchenshen@gmail.com> Signed-off-by: David S.
