* | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* netdev-dpdk: fix port addition for ports sharing same PCI idYuanhan Liu2018-01-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some NICs have only one PCI address associated with multiple ports. This patch extends the dpdk-devargs option's format to cater for such devices. To achieve that, this patch uses a new syntax that will be adapted and implemented in future DPDK release (likely, v18.05): http://dpdk.org/ml/archives/dev/2017-December/084234.html And since it's the DPDK duty to parse the (complete and full) syntax and this patch is more likely to serve as an intermediate workaround, here I take a simpler and shorter syntax from it (note it's allowed to have only one category being provided): class=eth,mac=00:11:22:33:44:55:66 Also, old compatibility is kept. Users can still go on with using the PCI id to add a port (if that's enough for them). Meaning, this patch will not break anything.

* netdev-dpdk: Fix requested MTU size validation.Ian Stokes2018-01-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit replaces MTU_TO_FRAME_LEN(mtu) with MTU_TO_MAX_FRAME_LEN(mtu) in netdev_dpdk_set_mtu(), in order to determine if the total length of the L2 frame with an MTU of ’mtu’ exceeds NETDEV_DPDK_MAX_PKT_LEN. When setting an MTU we first check if the requested total frame length (which includes associated L2 overhead) will exceed the maximum frame length supported in netdev_dpdk_set_mtu(). The frame length is calculated by MTU_TO_FRAME_LEN as MTU + ETHER_HEADER + ETHER_CRC. The MTU for the device will be set at a later stage in dpdk_eth_dev_init() using rte_eth_dev_set_mtu(mtu). However when using rte_eth_dev_set_mtu(mtu) the calculation used to check that the frame does not exceed the max frame length for that device varies between DPDK device drivers. For example ixgbe driver calculates the frame length for a given MTU as mtu + ETHER_HDR_LEN + ETHER_CRC_LEN i40e driver calculates it as mtu + ETHER_HDR_LEN + ETHER_CRC_LEN + I40E_VLAN_TAG_SIZE * 2 em driver calculates it as mtu + ETHER_HDR_LEN + ETHER_CRC_LEN + VLAN_TAG_SIZE Currently it is possible to set an MTU for a netdev_dpdk device that exceeds the upper limit MTU for that devices DPDK driver. This leads to a segfault. This is because the frame length comparison as is, does not take into account the addition of the vlan tag overhead expected in the drivers. The netdev_dpdk_set_mtu() call will incorrectly succeed but the subsequent dpdk_eth_dev_init() will fail before the queues have been created for the DPDK device. This coupled with assumptions regarding reconfiguration requirements for the netdev will lead to a segfault when the rxq is polled for this device. A simple way to avoid this is by using MTU_TO_MAX_FRAME_LEN(mtu) when validating a requested MTU in netdev_dpdk_set_mtu(). MTU_TO_MAX_FRAME_LEN(mtu) is equivalent to the following: mtu + ETHER_HDR_LEN + ETHER_CRC_LEN + (2 * VLAN_HEADER_LEN) By using MTU_TO_MAX_FRAME_LEN at the netdev_dpdk_set_mtu() stage, OvS now takes into account the maximum L2 overhead that a DPDK driver could allow for in its frame size calculation. This allows OVS to flag an error rather than the DPDK driver if the frame length exceeds the max DPDK frame length. OVS can fail gracefully at this point and use the default MTU of 1500 to continue to configure the port. Note: this fix is a work around, a better approach would be if DPDK devices could report the maximum MTU value that can be requested on a per device basis. This capability however is not currently available. A downside of this patch is that the MTU upper limit will be reduced by 8 bytes for DPDK devices that do not need to account for vlan tags in the frame length driver calculations e.g. ixgbe devices upper MTU limit is reduced from the OVS point of view from 9710 to 9702.

| | | | | | | | | | | | | | | | | | | | Controller actions have become more commonly used for purposes other than just making forwarding decisions (e.g., packet logging). A packet that needs to be copied to the controller and forwarded would always be sent to ovs-vswitchd to be handled, which could negatively affect performance and cause heavier CPU utilization in ovs-vswitchd. This commit changes the behavior so that OpenFlow controller actions become userspace datapath actions while continuing to let packet forwarding and manipulation continue to be handled by the datapath directly. This patch still slow-paths controller actions with the "pause" flag set. A future patch will stop slow-pathing these pause actions as well.

| * netdev-dpdk: vHost IOMMU supportMark Kavanagh2017-12-081-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DPDK v17.11 introduces support for the vHost IOMMU feature. This is a security feature, which restricts the vhost memory that a virtio device may access. This feature also enables the vhost REPLY_ACK protocol, the implementation of which is known to work in newer versions of QEMU (i.e. v2.10.0), but is buggy in older versions (v2.7.0 - v2.9.0, inclusive). As such, the feature is disabled by default in (and should remain so), for the aforementioned older QEMU verions. Starting with QEMU v2.9.1, vhost-iommu-support can safely be enabled, even without having an IOMMU device, with no performance penalty. This patch adds a new global config option, vhost-iommu-support, that controls enablement of the vhost IOMMU feature: ovs-vsctl set Open_vSwitch . other_config:vhost-iommu-support=true This value defaults to false; to enable IOMMU support, this field should be set to true when setting other global parameters on init (such as "dpdk-socket-mem", for example). Changing the value at runtime is not supported, and requires restarting the vswitch daemon.
