- Version bump to 2.9.0. Some of the changes are:
* NSH implementation now conforms to latest draft (draft-ietf-sfc-nsh-28).
* OVSDB:
- ovsdb-client: New "get-schema-cksum" and "query" commands.
- ovsdb-client: New "backup" and "restore" commands.
- ovsdb-client: New --timeout option.
- ovsdb-tool: New "db-name" and "schema-name" commands.
* ovs-vsctl and other commands that display data in tables now support a
--max-column-width option to limit column width.
* No longer slow-path traffic that sends to a controller. Applications,
such as OVN ACL logging, want to send a copy of a packet to a
controller while leaving the actual packet forwarding in the datapath.
* OVN:
- The "requested-chassis" option for a logical switch port now accepts a
chassis "hostname" in addition to a chassis "name".
- IPv6
* Added support to send IPv6 Router Advertisement packets in response to
the IPv6 Router Solicitation packets from the VIF ports.
* Added support to generate Neighbor Solicitation packets using the OVN
action 'nd_ns' to resolve unknown next hop MAC addresses for the
IPv6 packets.
- ovn-ctl: New commands run_nb_ovsdb and run_sb_ovsdb.
* OpenFlow:
- ct_clear action is now backed by kernel datapath. Support is probed for
when OVS starts.
- ovs-dpctl and related ovs-appctl commands:
* "flush-conntrack" now accept a 5-tuple to delete a specific
connection tracking entry.
* New "ct-set-maxconns", "ct-get-maxconns", and "ct-get-nconns" commands
for userspace datapath.
- No longer send packets to the Linux TAP device if it's DOWN unless it is
in another networking namespace.
* DPDK:
- Add support for DPDK v17.11
- Add support for vHost IOMMU
- New debug appctl command 'netdev-dpdk/get-mempool-info'.
* Custom statistics:
- DPDK physical ports now return custom set of "dropped", "error" and
"management" statistics.
- ovs-ofctl dump-ports command now prints new of set custom statistics
if available (for OpenFlow 1.4+).
- New appctl command 'dpif-netdev/pmd-rxq-rebalance' to rebalance rxq to
pmd assignments.
- Add rxq utilization of pmd to appctl 'dpif-netdev/pmd-rxq-show'.
- Add support for vHost dequeue zero copy (experimental)
* Userspace datapath:
- Output packet batching support.
* vswitchd:
- Datapath IDs may now be specified as 0x1 (etc.) instead of 16 digits.
- Configuring a controller, or unconfiguring all controllers, now deletes
all groups and meters (as well as all flows).
- New --enable-sparse configure option enables "sparse" checking by default.
- Added additional information to vhost-user status.
