A previous commit used the wrong DST port in the UDP header during Vxlan
Tx which caused Vxlan tunneling to break. Fixing it here..
Also included is a cosmetic fix in OvsDetectTunnelRxPkt() where we were
using htons() instead of ntohs(). Doesn't make a difference in practice
though.
One more change is, OvsIpHlprCbVxlan() has been nuked since it is not
used. Not sure if it is worth being resurrected.
Testing done: Ping across Vxlan tunnel and Stt tunnel.

Serializing between userspace flows and netlink attributes currently
requires several additional parameters besides the flows themselves.
This will continue to grow in the future as well. This converts
the function arguments to a parameters struct, which makes the code
easier to read and allowing irrelevant arguments to be omitted.

Support IGMPv3 messages with multiple records. Make sure all IGMPv3
messages go through slow path, since they may carry multiple multicast
addresses, unlike IGMPv2.
Tests done:
* multiple addresses in IGMPv3 report are inserted in mdb;
* address is removed from IGMPv3 if record is INCLUDE_MODE;
* reports sent on a burst with same flow all go to userspace;
* IGMPv3 reports go to mrouters, i.e., ports that have issued a query.

IGMP packets need to take the slow path. Otherwise, packets that match
the same flow will not be processed by OVS. That might prevent OVS from
updating the expire time for entries already in the mdb, but also to

When the filter detach routine is called while there are packets
still in processing, the OvsUninitSwitchContext function call will
decrement the switch context reference count without releasing the
switch context structure. This behaviour is correct and expected,
but the BSOD is caused in this case because the gOvsSwitchContext
variable is set to NULL, which is wrong.
The gOvsSwitchContext global variable must be set to NULL only when
the switch context structure is actually released.

It appears that miniflow_extract() in emc_processing() spends a lot of
cycles waiting for the packet's data to be read.
Prefetching the next packet's data while parsing removes this delay.
For a single flow pipeline the throughput improves by ~10%. With a
more realistic pipeline the change has a much smaller effect (~0.5%
improvement)

This patch adds support for a new port type to the userspace
datapath called dpdkvhostuser.
A new dpdkvhostuser port will create a unix domain socket which
when provided to QEMU is used to facilitate communication between
the virtio-net device on the VM and the OVS port on the host.
vhost-cuse ('dpdkvhost') ports are still available as 'dpdkvhostcuse'
ports and will be enabled if vhost-cuse support is detected in the
DPDK build specified during compilation of the switch. Otherwise,
vhost-user ports are enabled.

Add support for port mods in an OpenFlow 1.4 bundle, as required for
the minimum support level by the OpenFlow 1.4 specification. If the
bundle includes port mods, it may not specify the OFPBF_ATOMIC flag.
Port mods and flow mods in a bundle are always applied in order and
the consecutive flow mods between port mods are made available to
lookups atomically.
Note that ovs-ofctl does not support creating bundles with port mods.

After all, there are some cases in which both the insertion version
and removal version of a rule need to be considered. This makes the
cls_match a bit bigger, but makes classifier versioning much simpler
to understand.
Also, avoid using type larger than int in an enum, as it is not

Until now there have been two variants for --enable-dummy:
* --enable-dummy: This adds support for "dummy" dpif and netdev.
* --enable-dummy=override: In addition, this replaces *every* existing
dpif and netdev by the dummy type.
The latter is useful for testing but it defeats the possibility of using
the userspace native tunneling implementation (because all the tunnel
netdevs get replaced by dummy netdevs). Thus, this commit adds a third
variant:
* --enable-dummy=system: This replaces the "system" dpif and netdev
by dummies but leaves the others untouched.

This patch creates a new subpackage for OVN, openvswitch-ovn. It also
installs systemd unit files for ovn-controller and ovn-northd.
If you want to run ovn-controller:
# systemctl start ovn-controller
If you want to run ovn-northd:
# systemctl start ovn-northd
Both systemd units are currently set to depend on openvswitch. If
further ovsdb initialization is required for the OVN databases before
ovn-northd can start, that will be handled automatically by ovn-ctl
when you start the ovn-northd service.
This currently assumes that ovn-northd runs on the same host as
ovsdb-server that is hosting the OVN databases. That seems like a
reasonable assumption in the current architecture and can be evolved
later when needed.

This patch introduces ovn-ctl, which is similar to ovs-ctl. I opted
for a new script as everything in OVN so far is nicely isolated, so a
new script seemed to make the most sense.
If you'd like to run ovn-controller on a host already running ovs:
# ovn-ctl start_controller
If you'd like to run ovn-northd:
# ovn-ctl start_northd
Note that ovn-ctl assumes that ovn-northd is running on the same
server as ovsdb-server hosting the OVN databases. Based on the
current architecture this seems like a completely reasonable
assumption. This can be improved later when needed.
There's some additional stuff happening in start_northd to make the
experience nicer and not require additional steps by the
administrator. It creates the OVN dbs if they don't exist. If
ovsdb-server hasn't loaded them, it tells it to load them, as well.
ovn-ctl also supports running everything on the same host. This would
be common in a test environment with a single host or small set of
hosts. That would simply be:
# ovs-ctl start --system-id=random
# ovn-ctl start_northd
# ovn-ctl start_controller

OVSDB is transactional but it does not have built-in protection from dirty
reads. To avoid those, it's necessary to manually add verification to
transactions to ensure that any data reads whose values were essential to
later writes have not changed. ovn-controller didn't do that for
the "ports" column in the Bridge table, which means that if the set of
ports changed when it didn't expect it, it could revert changes made by
other database clients.
In particular this showed up in a scale test, where ovn-controller would
delete "vif" ports added via ovs-vsctl.
(It's easy to see exactly what happened by looking in the database log
with "ovsdb-tool -mm show-log".)

Postponed 'next' member poisoning was based on the faulty assumption
that postponed functions would be called in the order they were
postponed. This assumption holds only for the functions postponed by
any single thread. When functions are postponed by different
threads, there are no guarantees of the order in which the functions
may be called, or timing between those calls after the next grace
period has passed.
Given this, the postponed poisoning could have executed after
postponed destruction of the object containing the rculist element.
This bug was revealed after the memory leaks on rule deletion were
recently fixed.
This patch removes the postponed 'next' member poisoning and adds
documentation describing the ordering limitations in OVS RCU.

Handling evictions was broken in the previous patches. Eviction took
place early in the commit, and actually inappropriately bumped the
version number too early. Now eviction is treated much like a flow
modification, where a new rule replaces the old one, but just without
any 'inheritance' from the evicted rule to the new rule. This makes
evictions to be executed only when commit is successful, as evictions
are reverted like any other changes when the commit fails.

Each rule is now added or deleted in a specific tables version. Flow
tables are versioned with a monotonically increasing 64-bit integer,
where positive values are valid version numbers.
Rule modifications are implemented as an insertion of a new rule and a
deletion of the old rule, both taking place in the same tables
version. Since concurrent lookups may use different versions, both
the old and new rule must be available for lookups at the same time.
The ofproto provider interface is changed to accomodate the above. As
rule's actions need not be modified any more, we no longer need
'rule_premodify_actions', nor 'rule_modify_actions'. 'rule_insert'
now takes a pointer to the old rule and adds a flag that tells whether
the old stats should be forwarded to the new rule or not (this
replaces the 'reset_counters' flag of the now removed
'rule_modify_actions').
Versioning all flow table changes has the side effect of making
learned flows visible for future lookups only. I.e., the upcall that
executes the learn action, will not see the newly learned action in
it's classifier lookups. Only upcalls that start executing after the
new flow was added will match on it.

The traversal of the list of identical rules from the lookup threads

This patch simplifies the implementation of that list by making the
list NULL terminated, singly linked RCU-protected list. By having the
NULL at the end there is no longer a possiblity of missing the point
when the list wraps around. This is significant when there can be
multiple elements with the same priority in the list.
This change also decreases the size of the struct cls_match back
pre-'visibility' attribute size.

We formerly converted tunnel attributes to their flow representation
before formatting but now perform all operations directly on the
netlink attributes.
There is one remaining use of odp_tun_key_from_attr() that is not
used for the purposes of generating a flow. This is to check the
mask but this no longer makes sense given the way that we format
the flow itself. In fact, the code is not actually invoked any
more, so we can simply remove it.
This retains the special case for tunnels as a safety measure but it
should not matter in practice.
