[SR-Users] force_send_socket/$fs behaviour when binding to INADDR_ANY

[Alex Balashov]

Hello,

When binding Kamailio to 0.0.0.0, Kamailio no longer recognises any 
specific IP address homed on the system as being a "socket" for purposes 
of forcing traffic out of any specific interface (i.e. setting $fs), or 
any other purpose for which ingress and egress "sockets" are tracked 
(e.g. double RR).

As I understand it, this is because Kamailio considers only addresses 
explicitly specified via the 'listen' core config directive to be valid 
"send socket" arguments. Kamailio _will_ accept addresses already 
attached to the interface if it is bound interface-wise, e.g.

    listen=eth1:5060

but not when addresses are added to the interface without restarting the 
proxy:

# ip addr add dev eth1 172.30.110.10/24

Aug 10 17:31:35 centosity6 /usr/local/sbin/kamailio[28627]: WARNING: pv 
[pv_core.c:2285]: pv_set_force_sock(): no socket found to match 
[udp:172.30.110.10:5060]

Is there any straightforward way to modify this behaviour, so that it 
would be possible to dynamically add addresses to existing physical 
interfaces and get Kamailio to utilise them as if they were bound at 
boot time?

Thanks,
