Build Update for ovn-org/ovn
-------------------------------------

Build: #198
Status: Still Failing

Duration: 15 mins and 54 secs
Commit: 8bf9075 (master)
Author: Dumitru Ceara
Message: ovn-northd: Fix tunnel_key allocation for SB Port_Bindings.

When generating Port_Binding records ovn-northd tries to reuse the
tunnel_key value from the original SB record, if any available.

However, there's no check for tunnel_keys that would conflict with
newly allocated keys for new records. In order to avoid that, we
don't reuse stale Port_Binding entries, i.e., their "datapath" field
doesn't match the Datapath_Binding record associated with the
logical switch/router they're part of.

One way to reproduce the issue is:
$ ovn-nbctl ls-add ls1
$ ovn-nbctl ls-add ls2
$ ovn-nbctl lsp-add ls1 lsp1
$ ovn-nbctl lsp-add ls2 lsp2
$ ovn-nbctl --wait=sb sync
$ ovn-nbctl lsp-del lsp2 -- lsp-add ls1 lsp2

Another option to reproduce the issue is with HA_Chassis_Group:
$ ovn-nbctl ls-add ls1
$ ovn-nbctl ls-add ls2
$ ovn-nbctl lsp-add ls1 lsp1
$ ovn-nbctl lsp-add ls2 lsp2
$ ovn-nbctl lsp-set-type lsp2 external
$ ovn-nbctl ha-chassis-group-add chg1
$ ovn-nbctl ha-chassis-group-add-chassis chg1 chassis-1 30
$ chg1_uuid=$(ovn-nbctl --bare --columns _uuid list ha_Chassis_Group .)
$ ovn-nbctl set logical_switch_port lsp2 ha_chassis_group=${chg1_uuid}
$ ovn-nbctl lsp-del lsp2 -- lsp-add ls1 lsp2
