TIPC Cluster Domain Sockets / Tasks / #123 TIPC create udp socket with INADDR

Jon Paul Maloy - 2017-10-12

Hi,
You must attach to an interface which already has an IP (-v4 or -v6) address.
Example:

On one node:

node1 ~ # modprobe tipc
node1 ~ # tipc no set addr 1.1.1
node1 ~ # tipc be en me udp name udp1 localip 192.168.123.101

on another node:

node2 ~ # modprobe tipc
node2 ~ # tipc no set addr 1.1.2
node2 ~ # tipc be en me udp name udp1 localip 192.168.123.102

Then check if a link came up:

node2 ~ # tipc l l
broadcast-link: up
1.1.2:udp1-1.1.1:udp1: up

TIPC create udp socket with INADDR_ANY

When I enable bearer with media UDP, there is udp socke created with s_addr INADDR_ANY.
Can I change the addr to a specified ip like 192.168.1.1
udp 0 0 0.0.0.0:6118 0.0.0.0:*
Thanks

  Or you can substitute the ip for an ethernet device name. Unless that have
  changed.

    See Erik's comment below. Is this correct?
    I tried this:
    node1 ~ # tipc be en me udp name udp1 dev eth0
    but to no avail.
    
    Before looking more into the code I would like to know if anybody has made this work.
    And even if it doesn't it is not a bad idea.
    If it is implemented, but broken, we should fix it. Otherwise we should implement it.

Su Yu - 2017-10-12

Thank you very much for your reply.
Actually, in my env, all the tipc link is created, everythink is ok.
But only one thing confuse me.

After enable the bearer with UDP like below:
xx-0 computer:
tipc be en me udp name udp1 localip 192.168.1.3

xx-1 computer
tipc be en me udp name udp1 localip 192.168.1.4

In the computer , such as xx-0,
TIPC will listen at 0.0.0.0:6118
netstat -anp
udp 0 0 0.0.0.0:6118 0.0.0.0:*
But I only hope the 192.168.1.3:6118 is listend.

Thanks.

Su Yu - 2017-10-13

I just check the tipc code.
when tipc udp enable, it hard code the INADDR_ANY as local_ip.s_addr.
udp_conf.local_ip.s_addr = htonl(INADDR_ANY); [ tipc_udp_enable(), udp_media.c]
it won't use the local ip in the tipc config cmd:
tipc be en me udp name udp1 localip 192.168.123.101

So if tipc udp enable, it only listen 0.0.0.0:6118
netstat anp | grep 6118
udp 0 0 0.0.0.0:6118 0.0.0.0:*

Is it right?

Thanks.

  Not sure. I don't have time to check this further right now, but you could try to bind to a different interfaces/subnets on two peer nodes and see what happens. Foe Ethernet bearers we assume they are connected to logically separated subnets, and I suspect the UDP bearer was designed under the same assumption.

Hi Jon,

Erik's comment is correct! At currently, we can't use ethernet device name for media udp.

Hoang

  Hi Hoang,
  Forgot to ask you about this this morning, as your response is a little contradictory.
  Erik's comment says that this is possible, while your answer implies it is not.
  Which is correct?

Hi Jon,

So far, this function is not available at TIPC upstream as well as iproute2.
Probably, Erik mentioned this on some other development branch.
