Mosquitto client use Ethernet interface instead of loopback interface

[hasaafi]

With the version 1.4.14 i found that when :

• 1/ plugged ethernet ( between embedded device and pc ) no need for internet or any connectivity just plugged in the ethernet cable.

• 2/ run mosquitto localy and in loopback :
  - mosquitto with the default config : mosquitto -c /etc/mosquitto/mosquitto.conf -v -d
  - mosquitto_sub -h localhost -t topic/message &
  - mosquitto_pub -h localhost -m "hello" -t topic/message -d

-3/ unplugged ethernet.

=> Result : messages are buffered only when the ethernet is plugged.
if i unplugged the ethernet messages are not buffered
As soon as I plugged in the ethernet again, the messages are sent all at once.

when i check the mosquitto log, I found that the client use the IP of ethernet interface .

I tested with 1.5.8 version the problem is not seen . because they use the right interface( loopback interface) . which commit that fix this issue ?

I don't know. If this is important to you, you could run git bisect to find the commit.

the problem here that i use an old bsp : linux 3.10 so i can't test commits between this 2 version , mosquitto need dependencies so with the newest version i can't run it on my bsp.
I think that fixed in lib/net_mosq.c when they try to fixing another problem , but i can't find the commit
