[ovs-dev] [PATCH v2] ovn: Delete stale MAC_Bindings that result in Referential Integrity Violation

The MAC_Bindings have a strong reference to the Datapath_Binding. However the MAC_Bindings are never deleted anywhere, and when the Datapath (associated with a MAC_Binding) is deleted, the ovsdb-server returns Referential Integrity Violation. This prevents newer operations initiated from the CMS fr

Entries in MAC_Binding table are not deleted when the logical_ports referred to in MAC_Bindings are deleted. The patch fixes this by deleting the MAC_Binding entry when the logical_port is not found. Signed-off-by: Chandra Sekhar Vejendla --- ovn/controller/lflow.c | 25 +

[ovs-dev] [PATCH v6] ovn: Support for GARP for NAT IPs via localnet

In cases where a DNAT IP is moved to a new router or the SNAT IP is reused with a new mac address, the NAT IPs become unreachable because the external switches/routers have stale ARP entries. This commit aims to fix the problem by sending GARPs for NAT IPs via locanet. There are two parts to this p

[ovs-dev] [PATCH] ovn: Fix ARP request flow for unknown IP in lrouter

TPA in arp requests generated for unknown MAC-to-IP bindings is currently set to DST_IP of the original packet. These arps will not be resolved when the DST_IP is rechable via the default gateway. This patch fixes the issue by setting the TPA to reg0. In routing stage reg0 is set to IP of the defau
