-Post-v2.13.0
+Post-v2.15.0
+---------------------
+
+
+v2.15.0 - xx xxx xxxx
+---------------------
+ - 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+ * The terms "master" and "slave" have been replaced by "primary" and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+ * The term "slave" has been replaced by "member", for bonds, LACP, and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
+
+
+v2.14.0 - 17 Aug 2020
---------------------
- ovs-vswitchd no longer deletes datapath flows on exit by default.
- OpenFlow:
* Deprecated DPDK pdump packet capture support removed.
* Deprecated DPDK ring ports (dpdkr) are no longer supported.
* Add hardware offload support for VLAN Push/Pop actions (experimental).
+ * Add hardware offload support for matching IPv6 protocol (experimental).
+ * Add hardware offload support for set of IPv6 src/dst/ttl
+ and tunnel push-output actions (experimental).
+ * OVS validated with DPDK 19.11.2, due to the inclusion of fixes for
+ CVE-2020-10722, CVE-2020-10723, CVE-2020-10724, CVE-2020-10725 and
+ CVE-2020-10726, this DPDK version is strongly recommended to be used.
+ * New 'ovs-appctl dpdk/log-list' and 'ovs-appctl dpdk/log-set' commands
+ to list and change log levels in DPDK components.
+ * Vhost-user Dequeue zero-copy support is deprecated and will be removed
+ in the next release.
- Linux datapath:
* Support for kernel versions up to 5.5.x.
- AF_XDP:
* New configuration knob 'other_config:lb-output-action' for bond ports
that enables new datapath action 'lb_output' to avoid recirculation
in balance-tcp mode. Disabled by default.
+ * Add runtime CPU ISA detection to allow optimized ISA functions
+ * Add support for dynamically changing DPCLS subtable lookup functions
+ * Add ISA optimized DPCLS lookup function using AVX512
+ - New configuration knob 'other_config:bond-primary' for AB bonds
+ that specifies interface will be the preferred port if it is active.
- Tunnels: TC Flower offload
* Tunnel Local endpoint address masked match are supported.
* Tunnel Romte endpoint address masked match are supported.
+ - GTP-U Tunnel Protocol
+ * Add two new fields: tun_gtpu_flags, tun_gtpu_msgtype.
+ * Only support for userspace datapath.
v2.13.0 - 14 Feb 2020
- 'ovs-appctl dpctl/dump-flows' can now show offloaded=partial for
partially offloaded flows, dp:dpdk for fully offloaded by dpdk, and
type filter supports new filters: "dpdk" and "partially-offloaded".
- - GTP-U Tunnel Protocol
- * Add two new fields: tun_gtpu_flags, tun_gtpu_msgtype.
- * Only support for userspace datapath.
+ - Add new argument '--offload-stats' for command
+ 'ovs-appctl bridge/dump-flows',
+ so it can display offloaded packets statistics.
v2.12.0 - 03 Sep 2019
---------------------
* Add support for conntrack zone-based timeout policy.
- 'ovs-dpctl dump-flows' is no longer suitable for dumping offloaded flows.
'ovs-appctl dpctl/dump-flows' should be used instead.
- - Add new argument '--offload-stats' for command
- 'ovs-appctl bridge/dump-flows',
- so it can display offloaded packets statistics.
- Add L2 GRE tunnel over IPv6 support.
v2.11.0 - 19 Feb 2019
The implementation has been tested successfully against the Ixia Automated
Network Validation Library (ANVL).
- Stats are no longer updated on fake bond interface.
- - Keep active bond slave selection across OVS restart.
+ - Keep active bond interface selection across OVS restart.
- A simple wrapper script, 'ovs-docker', to integrate OVS with Docker
containers. If and when there is a native integration of Open vSwitch
with Docker, the wrapper script will be retired.
