Subject: [ovs-discuss] OVN DHCP implementation ignores broadcast bit


Hi All,

  I have OVN up and running (version 2.7), and it is working well except for 
one case. We have a VM which uses its own IP stack and does not accept unicast 
DHCP offers. After examining the OVN code, I found that it currently doesn't 
support the broadcast bit if set by the client.

  I didn't see any bugs regarding this, so I did a patch myself. The patch 
modifies put_dhcp_options to return 2 if the broadcast bit was set in the 
DISCOVER/REQUEST, and 1 if not set (both indicate success). Then I modified the 
current logical flow to check if the return code is 1, then execute the current 
logical flow. I added a new logical flow to handle the broadcast bit set case. 
If the return value from put_dhcp_options is 2, the new flow is executed which 
sets the dest MAC and dest IP to broadcast.

  I'd like to submit this. Do I just post it here?

Alex
