* dpdk: reflect status and version in the databaseAaron Conole2018-05-252-6/+29
| | | | | | | | | | | | | | | | The normal way of retrieving the running DPDK status involves parsing log files and issuing various incantations of ovs-vsctl and ovs-appctl commands to determine whether the rte_eal_init successfully started. This commit adds two new records to reflect the dpdk version, and the dpdk initialization status. To support this, the other_config:dpdk-init configuration block supports the 'true' and 'try' keywords now, instead of just 'true'.

* Configurable Link State Change (LSC) detection modeRóbert Mulik2018-05-111-0/+24
| | | | | | | | | | | It is possible to set LSC detection mode to polling or interrupt mode for DPDK interfaces. The default is polling mode. To set interrupt mode, option dpdk-lsc-interrupt has to be set to true. For detailed description and usage see the dpdk install documentation.

Start closing this gap by providing a standalone example of using these ports along with a little more detailed overview of the binding process. There is additional cleanup to be done for the DPDK howto, but that will be done separately. We enable the TODO directive so we can actually start calling out some TODOs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When explaining on how to add vhost-user ports to a guest, using libvirt, the following piece of configuration is used: <disk type='dir' device='disk'> <driver name='qemu' type='fat'/> <source dir='/usr/src/dpdk-stable-17.11.1'/> <target dev='vdb' bus='virtio'/> <readonly/> </disk> This is used to facilitate sharing of a DPDK directory between the host and the guest. However, for this to work selinux also needs to be configured (or disabled). Furthermore, if one is using Ubuntu, libvirtd would need to be added to complain only in AppArmor. Instead, in [1] it is advised to use wget to get the DPDK sources over the internet, which avoids this differentiation. Thus, we drop this piece of configuration here as well and keep the example configuration as simple as possible. This has been verified on both a Fedora 27 image and a Ubuntu 16.04 LTS image.

* | ovsdb: Introduce experimental support for clustered databases.Ben Pfaff2018-03-242-38/+398
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for OVSDB clustering via Raft. Please read ovsdb(7) for information on how to set up a clustered database. It is simple and boils down to running "ovsdb-tool create-cluster" on one server and "ovsdb-tool join-cluster" on each of the others and then starting ovsdb-server in the usual way on all of them. One you have a clustered database, you configure ovn-controller and ovn-northd to use it by pointing them to all of the servers, e.g. where previously you might have said "tcp:1.2.3.4" was the database server, now you say that it is "tcp:1.2.3.4,tcp:5.6.7.8,tcp:9.10.11.12". This also adds support for database clustering to ovs-sandbox. Acked-by: Justin Pettit <jpettit@ovn.org> Tested-by: aginwala <aginwala@asu.edu> Signed-off-by: Ben Pfaff <blp@ovn.org>

* | ovsdb-server: Add new RPC "set_db_change_aware".Ben Pfaff2018-03-241-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | The _Server database recently added to ovsdb-server can be used to dump out information about databases, but monitoring updates to _Server is not yet very useful because for historical reasons ovsdb-server drops all of its OVSDB connections whenever databases are added or removed or otherwise change in some major way. It is not a good idea to change this behavior for all clients, because some of them rely on it, but this commit introduces a new RPC that allows clients that understand _Server to suppress the connection-closing behavior. Signed-off-by: Ben Pfaff <blp@ovn.org>
* | ovsdb-server: Add support for a built-in _Server database.Ben Pfaff2018-03-241-0/+4
|/ | | | | | | | | | | | | | | | | | | | | The _Server database is valuable primarily because it provides database clients a way to find out the details of changes to databases, schemas, etc. in a granular, natural way. Until now, the only way that the server could notify clients about these kinds of changes was to close the session; when the client reconnects, it is expected to reassess the server's state. One way to provide this kind of granular information would be to add specific JSON-RPC requests to obtain notifications for different kinds of changes, but since ovsdb-server already provides granular and flexible notification support for databases, using a database for the purpose is convenient and avoids duplicating functionality. Initially this database only reports databases' names and schemas, but when clustering support is added in a later commit it will also report important aspects of clustering and cluster status. Thus, this database also reduces the need to add JSON-RPC calls to retrieve information about new features. Signed-off-by: Ben Pfaff <blp@ovn.org>

* poc: Introduce Proof of Concepts (Package building)Ansis Atteka2018-02-121-0/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch sets up foundations for Proof of Concepts that simply materialize documentation into Ansible instructions executed in virtualized Vagrant environment. This Proof of Concept allows to easily build: 1. *.deb packages on Ubuntu 16.04; AND 2. *.rpm packages on CentOS 7.4. It also sets up DEB and RPM repository over HTTP that can be used to pull these openvswitch packages with apt-get or yum from another host. This particular Proof of Concept is intended to address following use-cases: 1. for new OVS users to see how debian and rpm packages are built; 2. for developers to easily check for packaging build regressions; 3. for developers to easily share their sandbox builds into QE setups (opposed to manually copying binaries); 4. for developers to add other Proof of Concepts that possibly may require full end-to-end integration with other thirdparty projects (e.g. DPI, libvirt, IPsec) and need Open vSwitch packages.

* netdev-dpdk: Add support for vHost dequeue zero copy (experimental)Ciara Loftus2018-01-312-0/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Zero copy is disabled by default. To enable it, set the 'dq-zero-copy' option to 'true' when configuring the Interface: ovs-vsctl set Interface dpdkvhostuserclient0 options:vhost-server-path=/tmp/dpdkvhostuserclient0 options:dq-zero-copy=true When packets from a vHost device with zero copy enabled are destined for a single 'dpdk' port, the number of tx descriptors on that 'dpdk' port must be set to a smaller value. 128 is recommended. This can be achieved like so: ovs-vsctl set Interface dpdkport options:n_txq_desc=128 Note: The sum of the tx descriptors of all 'dpdk' ports the VM will send to should not exceed 128. Due to this requirement, the feature is considered 'experimental'. Testing of the patch showed a ~8% improvement when switching 512B packets between vHost devices on different VMs on the same host when zero copy was enabled on the transmitting device.
