When a logical_port is deleted and added back, in two sb transactions being handled within one ovn-controller loop, some flows belonging to the deleted pb (such as flows in OFTABLE_CHK_IN_PORT_SEC) are not properly deleted.
This can be reproduced with the following unit test
OVN_FOR_EACH_NORTHD([ AT_SETUP([Port Deleted and added back]) ovn_start net_add n1 sim_add hv1 as hv1 ovs-vsctl add-br br-phys ovn_attach n1 br-phys 192.168.0.1 ovn-appctl vlog/set dbg check ovs-vsctl -- add-port br-int hv1-vif1 -- \ set interface hv1-vif1 external-ids:iface-id=sw0-p1 \ options:tx_pcap=hv1/vif1-tx.pcap \ options:rxq_pcap=hv1/vif1-rx.pcap \ ofport-request=1 check ovn-nbctl ls-add sw0 check ovn-nbctl lsp-add sw0 sw0-p1 check ovn-nbctl lsp-set-addresses sw0-p1 "50:54:00:00:00:03 2001::3" check ovn-nbctl lsp-set-port-security sw0-p1 "50:54:00:00:00:03 2001::3" OVN_POPULATE_ARP wait_for_ports_up check ovn-nbctl --wait=hv sync ovn-sbctl list Port_Binding # Delete sw0-p1 sleep_controller hv1 check ovn-nbctl --wait=sb lsp-del sw0-p1 # Add back sw0-p1 but without any address set. check ovn-nbctl --wait=sb lsp-add sw0 sw0-p1 ovn-sbctl list Port_Binding wake_up_controller hv1 CHECK_FLOWS_AFTER_RECOMPUTE([hv1], [hv1]) OVN_CLEANUP([hv1]) AT_CLEANUP ])
