Re: [ovs-discuss] Build OpenvSwitch on Oracle Linux 8
Thanks Ben. I will keep hacking away at it. The protocols and design principles of Orabuntu-LXC require all installed software to be packaged - rpm or deb - so I will have to keep working on a solution to get the rpm package to build successfully. BTW that was a typo earlier - we had been using ovs 2.5.4 not 2.0.5 - sorry - 2.0.5 is the LXC version we were using for this testing Sent from my BlackBerry 10 smartphone.

In theory, I don't think we can avoid this because different datapath can have different actions for the same packet, so when a packet need to be sent to multiple datapaths, we will have to let it go through each steps following each datapath. In practice, the number of stages to go through depends on the number of output ports in the broadcast domain and the number of stages in each output port. To alleviate the problem, we should try our best to handle broadcast packets at the earliest stages of each datapath, and terminate the packet pipeline as early as possible, e.g. ARP reponse, to reduce the total number of resubmits. So I think what we can do are (although I hope there are better ways): - Increase the limit in OVS for the maximum allowed resubmit, considering the value for worst case reasonable real world deployment - Try to avoid large broadcast domain in deployment (of course, only when we have a choice) - See if there is optimization opportunity to move broadcast related processing earlier in pipeline and complete as early as possible for the processing for the packet.

[ovs-discuss] Too many resubmits in the OVS pipeline for scaled OVN topologies due to multicast_group implementation
Hi, We've hit a scaling issue recently [1] in the following topology: - External network connected to public logical switch "LS-pub" - ~300 logical networks (LR-i <--> LS-i <--> VMi) connected to LS-pub with dnat_and_snat rules. While trying to ping the VMs from outside the ARP request packet from the external host doesn't reach all the LR-i pipelines because it gets dropped due to "Too many resubmits". This happens because the MC_FLOOD group for LS-pub installs openflow entries that resubmit the packet: - through the patch ports towards all LR-i (one entry in table 32 with 300 resubmit actions). - to the egress pipeline for each VIF that's local to LS-pub (one entry in table 33). This means that for the ARP broadcast packet we'll execute the LR-i ingress/egress pipeline 300 times. For each execution we do a fair amount of resubmits through the different tables of the pipeline leading to a total number of resubmits for the single initial broadcast packet of more than 4K, the maximum allowed by OVS. After looking at the implementation I couldn't figure out a way to avoid running the full pipelines for each potential logical output port (patch or local VIF) because we might have flows later in the pipelines that perform actions based on the value of the logical output port (e.g., out ACL, qos). Do you think there's a different approach that we could use to implement flooding of broadcast/unknown unicast packets that would require less resubmit actions? This issue could also appear in a flat topology with a single logical switch and multiple VIFs (>300). In this case the resubmits would be part of the the openflow entry in table 33 but the result would be the same: too many resubmits due to the egress pipeline resubmits for each logical output port.
