When a port is replugged several times to the OVN bridge, its ofport will change.

ovn-controller doesn't seem to honor these changes in table 65 and traffic from such port will not work anymore.

The issue gets fixed triggering a recompute via: ovn-appctl -t ovn-controller recompute so everything seems to point to an issue of the incremental processing framework.

Tests have reported this failing with ovn2.13-20.06/20.09 and a scratch build rebased on 20.12.

Example:

Port with ofport 745 shows in table 0:

bash-4.4# ovs-ofctl dump-flows br-int table=0 | grep 745
 cookie=0x38937d8e, duration=40387.372s, table=0, n_packets=1863, n_bytes=111678, idle_age=1, priority=100,in_port=745 actions=load:0x4b->NXM_NX_REG13[],load:0x6a->NXM_NX_REG11[],load:0x69->NXM_NX_REG12[],load:0x18d->OXM_OF_METADATA[],load:0x1->NXM_NX_REG14[],resubmit(,8)


However 737 is used in table 65:


bash-4.4# ovs-ofctl dump-flows br-int table=65 | grep 8937d8e
 cookie=0x38937d8e, duration=40593.699s, table=65, n_packets=1848, n_bytes=98960, idle_age=2599, priority=100,reg15=0x1,metadata=0x18d actions=output:737


Older entry in the OVS database shows that 737 was the previous ofport of this port before it was re-added to the bridge:

record 6516: 2020-12-14 22:22:54.184
  table Interface row "tap71a5dfc1-10" (073801e2):
    ofport=737


I'm attaching NB/SB/OVS databases as well as physical and logical flows dumps for analysis.

Hi  Dumitru

   I failed to reproduce it. Could you help to check if I am missing something?

Steps:

	ovn-nbctl ls-add sw
	ovn-nbctl lsp-add sw lsp1
	ovn-nbctl lsp-add sw lsp2

	ovs-vsctl \
	    -- add-port br-int vm1 \
	    -- set Interface vm1  external_ids:iface-id=lsp1 \
	    ofport-request=1  
	ovs-vsctl \
	    -- add-port br-int vm2 \
	    -- set Interface vm2  external_ids:iface-id=lsp2 \
	    ofport-request=2


	for i in `seq 3 100`
	do
		ovs-vsctl \
		    -- del-port vm1 \
		    -- del-port vm2

		ovs-vsctl \
		    -- add-port br-int vm1 \
		    -- set Interface vm1  external_ids:iface-id=lsp1 \
		    ofport-request=$i  \
		    -- add-port br-int vm2 \
		    -- set Interface vm2  external_ids:iface-id=lsp2 \
		    ofport-request=$(($i+1))

	echo $i
	done

Hi Fei Liu,

With ovn2.13-20.09.0-23.el8fdp I did:

ovn-nbctl ls-add sw
ovn-nbctl lsp-add sw lsp1
ovn-nbctl lsp-add sw lsp2

ovs-vsctl \
    -- add-port br-int vm2 \
    -- set Interface vm2 type=internal \
    -- set Interface vm2  external_ids:iface-id=lsp2 \
    ofport-request=2

while [ $(ovn-sbctl show | grep -c Port_Binding) -ne 2 ]; do sleep 1; done;

ovn-appctl -t ovn-controller debug/pause
ovs-vsctl \
    -- del-port vm1 \
    -- del-port vm2

    -- add-port br-int vm1 \
