Build Update for ovsrobot/ovn
-------------------------------------

Build: #580
Status: Failed

Duration: 19 mins and 55 secs
Commit: fff5c95 (series_173823)
Author: Dumitru Ceara
Message: ovn-northd: Fix tunnel_key allocation for SB records.

When generating SB records that have tunnel_keys (e.g., Datapath,
Port_Binding, Multicast_Group) 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 first check that the tunnel_key value in the SB record doesn't
match a key already allocated by northd in the current run.
If there's a conflict, ovn-north will generate a new key for the SB
record.

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
