- OVSDB:
* Changed format in which ovsdb transactions are stored in database files.
Now each transaction contains diff of data instead of the whole new
value of a column.
New ovsdb-server process will be able to read old database format, but
old processes will *fail* to read database created by the new one.
For cluster and active-backup service models follow upgrade instructions
in 'Upgrading from version 2.14 and earlier to 2.15 and later' section
of ovsdb(7).
* New unixctl command 'ovsdb-server/get-db-storage-status' to show the
status of the storage that's backing a database.
* New unixctl command 'ovsdb-server/memory-trim-on-compaction on|off'.
If turned on, ovsdb-server will try to reclaim all the unused memory
after every DB compaction back to OS. Disabled by default.
* Maximum backlog on RAFT connections limited to 500 messages or 4GB.
Once threshold reached, connection is dropped (and re-established).
Use the 'cluster/set-backlog-threshold' command to change limits.
- DPDK:
* Removed support for vhost-user dequeue zero-copy.
* Add support for DPDK 20.11.
- Userspace datapath:
* Add the 'pmd' option to "ovs-appctl dpctl/dump-flows", which
restricts a flow dump to a single PMD thread if set.
* New 'options:dpdk-vf-mac' field for DPDK interface of VF ports,
that allows configuring the MAC address of a VF representor.
* Add generic IP protocol support to conntrack. With this change, all
none UDP, TCP, and ICMP traffic will be treated as general L3
traffic, i.e. using 3 tupples.
* Add parameters 'pmd-auto-lb-load-threshold' and
'pmd-auto-lb-improvement-threshold' to configure PMD auto load balance
behaviour.
- The environment variable OVS_UNBOUND_CONF, if set, is now used
as the DNS resolver's (unbound) configuration file.
- Linux datapath:
* Support for kernel versions up to 5.8.x.
- Terminology:
* The terms "master" and "slave" have been replaced by "primary" and
"secondary", respectively, for OpenFlow connection roles.
* The term "slave" has been replaced by "member", for bonds, LACP, and
OpenFlow bundle actions.
- Support for GitHub Actions based continuous integration builds has been
added.
- Bareudp Tunnel
* Bareudp device support is present in linux kernel from version 5.7
* Kernel bareudp device is not backported to ovs tree.
* Userspace datapath support is not added
- ovs-dpctl and 'ovs-appctl dpctl/':
* New commands '{add,mod,del}-flows' where added, which allow adding,
deleting, or modifying flows based on information read from a file.
- IPsec:
* Add option '--no-cleanup' to allow ovs-monitor-ipsec to stop without
tearing down IPsec tunnels.
* Add option '--no-restart-ike-daemon' to allow ovs-monitor-ipsec to start
without restarting ipsec daemon.
- Building the Linux kernel module from the OVS source tree is deprecated
* Support for the Linux kernel is capped at version 5.8
* Only bug fixes for the Linux OOT kernel module will be accepted.
* The Linux kernel module will be fully removed from the OVS source tree
in OVS branch 2.18
fix some do_patch error about local patch.

A mostly straightforward uprev. Unfortunately a required patch for
python3 is only available on a non-release branch so we must carry it
in order to build (the discussion on the mailing list was that an
uprev might have avoided this, but this is not the case).
The ptest results are similar to after the v2.11 uprev
ERROR: 2413 tests were run,
23 failed unexpectedly.
383 tests were skipped.
NOTE, however, that they have now marked many tests as 'skipped', such
as the python2 results, so the failed and skipped numbers have
essentially swapped with each other. The failed tests were in the
following areas:
checkpatch.at (5)
ovs-ofctl.at (1)
dpif-netdev.at (1)
ofproto-dpif.at (6)
bridge.at (2)
ovn.at (2)
ovn-controller-vtep.at (6)
Most were issues with the test or expectations that source code would
be available. There might be an issue around packaging of
"/vswitchd/vswitch.ovsschema" but we should be able to overlook this
for now, as we have with previous versions.

The service currently fails to run since the runtime directories
aren't being created. Create the runtime directories and fixup the
path to echo to get things working again.

The current version (v2.9.3) started to fail to build due to changes
in openssl. Upstream must have run into similar issues as this was
identified and addressed in v2.10.0 by including a copy of
'dhparams.c' instead of relying on it being generated. (see commit
"dhparams: Add pregenerated .c file to the repository.")
Additionally v2.10.0 is better aligned for our kernel and dpdk
versions:
kernel
===
2.10.x 3.10 to 4.17
dpdk
===
2.10.x 17.11.3
The changes in this commit allow for the building of v2.10.0. A second
commit will be necessary to deal with a few runtime changes which
prevent ovsdb-server from starting correctly.

This brings us up to date with the latest upstream release. I suspect
there will be an upcoming release to add compatibility with DPDK
v18.05 (the DPDK release is due out any day now) but getting this
fairly large release bump out of the way first will facilitate any
upcoming uprev.
We are able to drop they python3 patches as they have been merged
upstream. Some scripts which needed to be updated to use python3
disappeared, new ones appeared so the 'use python3' patches are
updated accordingly. Beyond this the biggest change is related to the
systemd unit files, the ovsdb-server has been updated upstream to be
generated on the fly via the spec file, we mimic this in the
install_prepend. We also add the various configuration files which the
unit files source before launching the services.
As usual this was tested against out typical usecases including usage
in meta-overc. As well the ptests have been run and the results are no
better or worse.
Previous version:
ERROR: 2332 tests were run,
21 failed unexpectedly.
3 tests were skipped.
New version:
ERROR: 2527 tests were run,
29 failed unexpectedly.
3 tests were skipped.
