chandrav | rtheis: ping | 20:39 |
rtheis | chandrav: hi | 20:39 |
chandrav | Hi richard | 20:39 |
chandrav | so, i wanted to discuss about the transit network ports and the need to store them in neutron | 20:40 |
rtheis | ok | 20:40 |
chandrav | you were suggesting that we can handle in ovn without neutron | 20:40 |
rtheis | yes, I was wondering if that was possible | 20:40 |
chandrav | ALL we need is a set of IP and MACs | 20:40 |
chandrav | i wasnt sure how to generate mac addresses, which will not collide with anything else in neutron | 20:41 |
chandrav | thats the sole reason why i coded it that way | 20:41 |
rtheis | I see... looking at neutron code now | 20:43 |
rtheis | chandrav: when a port is created without a mac address specified, it appears that self._generate_mac() is called | 20:47 |
rtheis | which calls utils.get_random_mac(cfg.CONF.base_mac.split(':')) | 20:47 |
rtheis | which doesn't check for duplicates | 20:47 |
rtheis | and when a mac address is specified, _is_mac_in_use is called | 20:48 |
rtheis | but that is specific to the network | 20:49 |
rtheis | Are you looking for a globally unique mac address ? | 20:49 |
chandrav | no | 20:50 |
rtheis | Maybe calling utils.get_random_mac(cfg.CONF.base_mac.split(':')) is sufficient | 20:52 |
rtheis | we use it today http://git.openstack.org/cgit/openstack/networking-ovn/tree/networking_ovn/ml2/mech_driver.py#n430 | 20:53 |
chandrav | Thanks rthies: I'll take a look. I am game for not storing it in neutron | 20:56 |
rtheis | chandrav: thanks for taking a look | 20:57 |
chandrav | rtheis: I take back by statement about the no need for globally unique mac address. | 21:05 |
chandrav | we will be using the mac address in the ovn datapath, so it has to be unique | 21:06 |
rtheis | okay, we'll then I don't think you get that from either method | 21:06 |
chandrav | yeah | 21:06 |
chandrav | even when we create a port without specifying the mac address, neutron is checking if the mac_address is in use, if yes, it does retires before erroring out | 21:07 |
chandrav | so i dont see a way out without storing in neutron | 21:07 |
rtheis | but does neutron actually check beyond the network | 21:07 |
rtheis | That is, I only see it looking for duplicates on the same network | 21:08 |
rtheis | So I don't see it catching a duplicate between the transit network and another network | 21:08 |
chandrav | yeah | 21:09 |
rtheis | So we may need something like dvr_base_mac | 21:09 |
rtheis | Which is basically a different starting base mac | 21:09 |
rtheis | utils.get_random_mac(cfg.CONF.dvr_base_mac.split(':')) | 21:10 |
rtheis | This is what the neutron dvr code uses | 21:10 |
chandrav | are there rules, which govern the base mac usage > | 21:11 |
chandrav | ? | 21:11 |
rtheis | only those that I can gather from reading the code | 21:13 |
rtheis | you could ask on #openstack-neutron for more details | 21:15 |
chandrav | thans rheis | 21:15 |
rtheis | chandrav: it appears base mac is for (non-dvr) ports created without mac address specified. | 21:16 |
rtheis | but it appears that you can specify a mac address that doesn't conform to base_mac | 21:17 |
rtheis | as long as it isn't in use on the network | 21:17 |
rtheis | for the port | 21:17 |
rtheis | If we have a l3_base_mac that is unique from neutron base_mac and dvr_base_mac then there could only be conflicts with those creating ports by specifying these reserved macs | 21:19 |
rtheis | so it would be up to ovn driver to prevent these reserved macs from being used | 21:20 |
rtheis | ml2 ovn driver | 21:20 |
