Hi, folks
I’m changing Openstack Neutron to use openflow-based pipeline to implement
qrouter and floating IP, everything is ok when two VMs (which are in two
different compute nodes and two subnets but same network, so vlan tag is same),
but NORMAL action will drop packets if they are on

Hello,
I was having a look at the calendar and realized that tomorrow (6
August) is our scheduled soft freeze date for OVN 21.09. Since I did a
poor job of notifying people about this, I think it is OK for us to
extend the soft freeze by one week. So soft freeze for OVN 21.09 will be

Hi,
I’m trying to implement multiple routing tables support for Logical Routers and
met some difficulties, need help/advice.
How I see it can be used by administrators:
1. In LRP’s options field is added key route_table with the routing table’s
name - any string.
2. When adding new logical

Good point, OVS is unable to parse them. I don't see anywhere in the OVS
code that relies on these fields being printed.
I could replace them with the default 'tp_src/dst' in this workaround, so
as not to break any scripts.
That being said, I am not sure how these fields would currently even end

By default, OVN support only one DGP (distributed gateway port) per
logical router. While a single DGP port suffices for most of the North
South connectivity, there are requirements where a logical router could
be connected to multiple external networks and based on routing
The commit 1c9e46ab5 removed the outport match from the lflows, which
leads to a problem for gateway routers that have multiple ports
configured with different MTUs. For example, R0 has port P1, P2 and P3.
P2 and P3 both have gateway_mtu configured: P2 mtu = 1400, P3 mtu = 1500.
Below lflows are
V2:
- Converted to a series and added patch-1 that fixes a problem of an upstream
commit, which was found during rebasing.
- Rebased on upstream.
- Addressed comments of V1 from Numan.

When OVN is linked with an appropriate plugging implementation,
CMS can request OVN to plug individual lports into the local
Open vSwitch instance.
The port and instance record will be maintained during the lifetime
of the lport and it will be removed on release of lport.
TODO: The functions
To be able to effectively remove ports previously plugged by us
we need to look up ports by interface records.

Up until now the controller patch module has been the only
consumer of functions to maintain OVS ports and interfaces.
With the introduction of infrastructure for plugging providers
these functions will also be consumed by the controller binding
module.
As such we introduce a new module called
Make use of the common functions for maintaining OVS ports.

If we are not obtaining any useful information out of the poll(),
such as is a fd busy or not, we do not need to do a poll() if
an immediate_wake() has been requested.
This cuts out all the pollfd hash additions, forming the poll
arguments and the actual poll() after a call
From: Anton Ivanov
time_poll() makes an excessive number of time_msec() calls
which incur a performance penalty.
1. Avoid time_msec() call for timeout calculation when time_poll()
is asked to skip poll()
2. Reuse the time_msec() result from deadline calculation for
last_wakeup and timeout

Currently, ovn-controller generates N x V OpenFlow
hairpin flows where:
N = number of datapaths
V = number of LB VIPs
In a scale setup with 120 nodes, 15k VIPs, and 3 Protocols,
this can generate 5.4M OpenFlows in the OFTABLE_CT_SNAT_FOR_VIP

'sent_node' is initialized to all zeroes by xzalloc(), but
HMAP_NODE_NULL is not all zeroes. hmap_node_is_null() is used
