Hi,
While testing out SCTP multihoming, I have run into an issue with the
wrong IP address showing up in the notification received from the SCTP
stack by an application.
I am using kernel 2.6.27 (SuSE 11.1 on 64-bit)
The remote end (IP-A) sends out two IP addresses (A and B) in the INIT-ACK.
I remove the network cable for A and heartbeats fail as expected.
But application receives a notification for B instead of A.
Heartbeats to B are ack'ed and can be seen in the packet traces, and
heartbeats to A are not ack'ed.
10.214.64.100 --- INIT ---> 10.214.65.200 (A)
(A) 10.214.65.200 --- INIT-ACK ---> 10.214.64.100
INIT-ACK contains: IPv4 address params:
A - 10.214.65.200 (vlan1)
B - 10.215.65.200 (vlan2)
10.214.64.100 --- HEARTBEAT ---> 10.214.65.200 (A) - (Heartbeat fails
since ethernet wire to 10.214.65.200 is pulled out from switch)
No heartbeat-ack received from IP-A.
Application receives SCTP_PEER_ADDR_CHANGE notification with state
SCTP_ADDR_UNREACHABLE for
10.215.65.200 (B) instead of IP-A.
Any help would be appreciated.
Thanks,
Bhaskar
