OVN is the main candidate for conditional monitoring usage. It is clear that
conditional monitoring reduces computation on the ovn-controller (client) side
due to the reduced size of flow tables and update messages. Performance
evaluation shows up to 75% computation reduction.
However, performance evaluation shows also a reduction in computation on the SB
ovsdb-server side proportional to the degree that each logical network is
spread over physical hosts in the DC. Evaluation shows that in a realistic
scenarios there is a computation reduction also in the server side.
Evaluation on simulated environment of 50 hosts and 1000 logical ports shows
the following results (cycles #):

ovn-controller: Drop remove_local_datapath_by_binding().
ovn-controller has an hmap called 'local_datapaths' which tracks
all OVN datapaths that have at least one port binding on the local
chassis. This patch corrects the case where a port binding row is
deleted from the southbound DB while it's still bound to the chassis,
meaning it was deleted before the ovs interface was deleted.
The previous code tried to handle this case by calling
remove_local_datapath_by_binding(). The function appears to try
to look up local_datapath by the binding UUID. If it finds it,
it will delete the local datapath entry. On the surface, this
looks like a bug where it deletes a local datapath entry even
when there could be other ports still bound to the chassis.
The reality is that this function was always a no-op. It was
doing a lookup using a different hash value than how local_datapath
entries are actually hashed. In practice, this wasn't a big problem
because local_datapaths are correctly cleaned in in the
process_full_binding case after an ovs interface is added or removed.
The new change ensures that we run the process_full_binding code
in this case right away, even if the interface is not deleted.

Upstream commit:
commit
fe3a5f6c795810edb1646a840fec3c8c350c2a4e
Author: Simon Horman <simon.horman@netronome.com>
openvswitch: allow output of MPLS packets on tunnel vports
Currently output of MPLS packets on tunnel vports is not allowed by Open
vSwitch. This is because historically encapsulation was done in such a way
that the inner_protocol field of the skb needed to hold the inner protocol
for both MPLS and tunnel encapsulation in order for GSO segmentation to be
performed correctly.
Since
b2acd1dc3949 ("openvswitch: Use regular GRE net_device instead of
vport") Open vSwitch makes use of lwt to output to tunnel netdevs which
perform encapsulation. As no drivers expose support for MPLS offloads this
means that GSO packets are segmented in software by validate_xmit_skb(),
which is called from __dev_queue_xmit(), before tunnel encapsulation occurs.
This means that the inner protocol of MPLS is no longer needed by the time
encapsulation occurs and the contention on the inner_protocol field of the
skb no longer occurs.
Thus it is now safe to output MPLS to tunnel vports.

openvswitch: update checksum in {push,pop}_mpls
In the case of CHECKSUM_COMPLETE the skb checksum should be updated in
{push,pop}_mpls() as they the type in the ethernet header.
As suggested by Pravin Shelar.

ovs: allow nl 'flow set' to use ufid without flow key
When we want to change a flow using netlink, we have to identify it to
be able to perform a lookup. Both the flow key and unique flow ID
(ufid) are valid identifiers, but we always have to specify the flow
key in the netlink message. When both attributes are there, the ufid
is used. The flow key is used to validate the actions provided by
the userland.
This commit allows to use the ufid without having to provide the flow
key, as it is already done in the netlink 'flow get' and 'flow del'
path. The flow key remains mandatory when an action is provided.

When an error occurs skipping IPv6 extension headers retain the already

that is always use the frag_off value set by ipv6_skip_exthdr().

openvswitch: allow management from inside user namespaces
Operations with the GENL_ADMIN_PERM flag fail permissions checks because
this flag means we call netlink_capable, which uses the init user ns.
Instead, let's introduce a new flag, GENL_UNS_ADMIN_PERM for operations
which should be allowed inside a user namespace.
The motivation for this is to be able to run openvswitch in unprivileged
containers. I've tested this and it seems to work, but I really have no
idea about the security consequences of this patch, so thoughts would be
much appreciated.
v2: use the GENL_UNS_ADMIN_PERM flag instead of a check in each function
v3: use separate ifs for UNS_ADMIN_PERM and ADMIN_PERM, instead of one
massive one

system-common-macros: Enhance ADD_VETH to take mac and gateway.
It is useful to set the mac address and gateway while using ADD_VETH
to connect a namespace to a OVN logical topology. Upcoming commits
use this enhancement.

ovn: Support multiple addresses on a single logical router port.
Supporting multiple addresses is only mildly interesting for IPv4.
However, it is a requirement for IPv6, which will arrive in a future
commit.
This commit introduces the extract_lrp_networks() function to ovn-util.[ch].
