FD.io CSIT performance lab is testing VPP vhost-user with KVM VMs using
following environment settings:
-- Tests with varying QEMU virtio queue (a.k.a. vring) sizes: [vr1024]
- 1024 descriptors to optimize for packet throughput.
-- Tests with varying Linux :abbr:`CFS (Completely Fair Scheduler)`
- settings: i) [cfs] default settings, ii) [cfsrr1] CFS RoundRobin(1)
- policy applied to all data plane threads handling test packet path
- including all VPP worker threads and all QEMU testpmd poll-mode
- threads.
-- Resulting test cases are all combinations with [vr1024] and
- [cfs,cfsrr1] settings.
-- Adjusted Linux kernel :abbr:`CFS (Completely Fair Scheduler)`
- scheduler policy for data plane threads used in CSIT is documented in
- `CSIT Performance Environment Tuning wiki
- <https://wiki.fd.io/view/CSIT/csit-perf-env-tuning-ubuntu1604>`_.
-
-Testing with different CFS settings enables verifying the impact of
-making VPP and VM data plane threads less susceptible to other Linux OS
-system tasks hijacking CPU cores running those data plane threads.

VPP_Device Functional
---------------------
-|csit-release| added new VPP_Device test environment for functional VPP
+|csit-release| includes VPP_Device test environment for functional VPP
device tests integrated into LFN CI/CD infrastructure. VPP_Device tests
run on 1-Node testbeds (1n-skx, 1n-arm) and rely on Linux SRIOV Virtual
Function (VF), dot1q VLAN tagging and external loopback cables to
facilitate packet passing over exernal physical links. Initial focus is
-on few baseline tests. Existing CSIT VIRL tests can be moved to
-VPP_Device framework by changing L1 and L2 KW(s). RF test definition
-code stays unchanged with the exception of requiring adjustments from
-3-Node to 2-Node logical topologies. CSIT VIRL to VPP_Device migration
-is expected in the next CSIT release.

-Linux CFS Tunings
-~~~~~~~~~~~~~~~~~
-
-Linux CFS scheduler tunings are applied to all QEMU vCPU worker threads
-(the ones handling testpmd PMD threads) and VPP data plane worker
-threads. List of VPP data plane threads can be obtained by running:
-
-::
-
- $ for psid in $(pgrep vpp)
- $ do
- $ for tid in $(ps -Lo tid --pid $psid | grep -v TID)
- $ do
- $ echo $tid
- $ done
- $ done
-
-Or:
-
-::
-
- $ cat /proc/`pidof vpp`/task/*/stat | awk '{print $1" "$2" "$39}'
-
-CFS round-robin scheduling with highest priority is applied using:
-
-::
-
- $ for psid in $(pgrep vpp)
- $ do
- $ for tid in $(ps -Lo tid --pid $psid | grep -v TID)
- $ do
- $ chrt -r -p 1 $tid
- $ done
- $ done

+Abstract
+--------
+
+FD.io VPP software data plane technology has become very popular across
+a wide range of VPP eco-system use cases, putting higher pressure on
+continuous verification of VPP software quality.
+
+This document describes a proposal for design and implementation of extended
+continuous VPP testing by extending existing test environments.
+Furthermore it describes and summarizes implementation details of Integration
+and System tests platform *1-Node VPP_Device*. It aims to provide a complete
+end-to-end view of *1-Node VPP_Device* environment in order to improve
+extendability and maintenance, under the guideline of VPP core team.
+
+The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",

+
+Physical Testbeds
+-----------------
+
+All :abbr:`FD.io (Fast Data Input/Ouput)` :abbr:`CSIT (Continuous System
+Integration and Testing)` vpp-device tests are executed on physical testbeds
+built with bare-metal servers hosted by :abbr:`LF (Linux Foundation)` FD.io
+project. Two 1-node testbed topologies are used:
+
+- **2-Container Topology**: Consisting of one Docker container acting as SUT
+ (System Under Test) and one Docker container as TG (Traffic Generator), both
+ connected in ring topology via physical NIC cross-connecting.
+
+Current FD.io production testbeds are built with servers based on one
+processor generation of Intel Xeons: Skylake (Platinum 8180). Testbeds built
+with servers based on Arm processors are in the process of being added to FD.io
+production.
+
+Following section describe existing production 1n-skx testbed.
+
+1-Node Xeon Skylake (1n-skx)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1n-skx testbed is based on single SuperMicro SYS-7049GP-TRT server equipped with
+two Intel Xeon Skylake Platinum 8180 2.5 GHz 28 core processors. Physical
+testbed topology is depicted in a figure below.

+
+Server is populated with the following NIC models:
+
+#. NIC-1: x710-da4 4p10GE Intel.
+#. NIC-2: x710-da4 4p10GE Intel.
+
+All Intel Xeon Skylake servers run with Intel Hyper-Threading enabled,
+doubling the number of logical cores exposed to Linux, with 56 logical
+cores and 28 physical cores per processor socket.
+
+NIC interfaces are shared using Linux vfio_pci and VPP VF drivers:
+
+- DPDK VF driver,
+- Fortville AVF driver.
+
+Provided Intel x710-da4 4p10GE NICs support 32 VFs per interface, 128 per NIC.
+
+Complete 1n-skx testbeds specification is available on `CSIT LF Testbeds
+<https://wiki.fd.io/view/CSIT/Testbeds:_Xeon_Skx,_Arm,_Atom.>`_ wiki page.
+
+Total of two 1n-skx testbeds are in operation in FD.io labs.
+
+1-Node Virtualbox (1n-vbox)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+1n-skx testbed can run in single VirtualBox VM machine. This solution replaces
+the previously used Vagrant environment based on 3 VMs.
+
+VirtualBox VM MAY be created by Vagrant and MUST have additional 4 virtio NICs
+each pair attached to separate private networks to simulate back-to-back
+connections. It SHOULD be 82545EM device model (otherwise can be changed in
+boostrap scripts). Example of Vagrant configuration:
+
+::
+
+ Vagrant.configure(2) do |c|
+ c.vm.network "private_network", type: "dhcp", auto_config: false,
+ virtualbox__intnet: "port1", nic_type: "82545EM"
+ c.vm.network "private_network", type: "dhcp", auto_config: false,
+ virtualbox__intnet: "port2", nic_type: "82545EM"
+
+ c.vm.provider :virtualbox do |v|
+ v.customize ["modifyvm", :id, "--nicpromisc2", "allow-all"]
+ v.customize ["modifyvm", :id, "--nicpromisc3", "allow-all"]
+ v.customize ["modifyvm", :id, "--nicpromisc4", "allow-all"]
+ v.customize ["modifyvm", :id, "--nicpromisc5", "allow-all"]
+
+Vagrant VM is populated with the following NIC models:
+
+#. NIC-1: 82545EM Intel.
+#. NIC-2: 82545EM Intel.
+#. NIC-3: 82545EM Intel.
+#. NIC-4: 82545EM Intel.
+
+Containers
+----------
+
+It was agreed on :abbr:`TWS (Technical Work Stream)` call to continue with
+Ubuntu 18.04 LTS as a baseline system with OPTIONAL extend to Centos 7 and
+SuSE per demand [TWSLink]_.
+
+All :abbr:`DCR (Docker container)` images are REQUIRED to be hosted on Docker
+registry available from LF network, publicly available and trackable. For
+backup, tracking and contributing purposes all Dockerfiles (including files
+needed for building container) MUST be available and stored in [fdiocsitgerrit]_
+repository under appropriate folders. This allows the peer review process to be
+done for every change of infrastructure related to scope of this document.
+Currently only **csit-shim-dcr** and **csit-sut-dcr** containers will be stored
+and maintained under CSIT repository by CSIT contributors.
+
+At the time of designing solution described in this document the interconnection
+between [dockerhub]_ and [fdiocsitgerrit]_ for automated build purposes and
+image hosting cannot be established with the trust and respectful to
+security of FD.io project. Unless adressed, :abbr:`DCR` images will be placed in
+custom registry service [fdioregistry]_. Automated Jenkins jobs will be created
+in align of long term solution for container lifecycle and ability to build
+new version of docker images.
+
+In parallel, the effort is started to find the outsourced Docker registry
+service.
+
+Versioning
+~~~~~~~~~~
+
+As of initial version of vpp-device, we do have only single latest version of
+Docker image hosted on [dockerhub]_. This will be addressed as further
+improvement with proper semantic versioning.
+
+jenkins-slave-dcr
+~~~~~~~~~~~~~~~~~
+
+This :abbr:`DCR` acts as the Jenkins slave (known also as jenkins minion). It
+can connect over SSH protocol to TCP port 6022 of **csit-shim-dcr** and executes
+non-interactive reservation script. Nomad is responsible for scheduling this
+container execution onto specific **1-Node VPP_Device** testbed. It executes
+:abbr:`CSIT` environment including :abbr:`CSIT` framework.
+
+All software dependencies including VPP/DPDK that are not present in
+**csit-sut-dcr** container image and/or needs to be compiled prior running on
+**csit-sut-dcr** SHOULD be compiled in this container.
+
+- *Container Image Location*: Docker image at snergster/vpp-ubuntu18.
+
+- *Container Definition*: Docker file specified at [JenkinsSlaveDcrFile]_.
+
+- *Initializing*: Container is initialized from within *Consul by HashiCorp*
+ and *Nomad by HashiCorp*.
+
+csit-shim-dcr
+~~~~~~~~~~~~~
+
+This :abbr:`DCR` acts as an intermediate layer running script responsible for
+orchestrating topologies under test and reservation. Responsible for managing VF
+resources and allocation to :abbr:`DUT (Device Under Test)`, :abbr:`TG
+(Traffic Generator)` containers. This MUST to be done on **csit-shim-dcr**.
+This image also acts as the generic reservation mechanics arbiter to make sure
+that only Y number of simulations are spawned on any given HW node.
+
+- *Container Image Location*: Docker image at snergster/csit-shim.
+
+- *Container Definition*: Docker file specified at [CsitShimDcrFile]_.
+
+- *Initializing*: Container is initialized from within *Consul by HashiCorp*
+ and *Nomad by HashiCorp*. Required docker parameters, to be able to run
+ nested containers with VF reservation system are: privileged, net=host,
+ pid=host.
+
+- *Connectivity*: Over SSH only, using <host>:6022 format. Currently using
+ *root* user account as primary. From the jenkins slave it will be able to
+ connect via env variable, since the jenkins slave doesn't actually know what
+ host its running on.
+
+ ::
+
+ ssh -p 6022 root@10.30.51.node
+
+csit-sut-dcr
+~~~~~~~~~~~~
+
+This :abbr:`DCR` acts as an :abbr:`SUT (System Under Test)`. Any :abbr:`DUT` or
+:abbr:`TG` application is installed there. It is RECOMMENDED to install DUT and
+all DUT dependencies via commands ``rpm -ihv`` on RedHat based OS or ``dpkg -i``
+on Debian based OS.
+
+Container is designed to be a very lightweight Docker image that only installs
+packages and execute binaries (previously built or downloaded on
+**jenkins-slave-dcr**) and contains libraries necessary to run CSIT framework
+including those required by DUT/TG.
+

+
+Container required to run as ``--privileged`` due to ability to create nested
+containers and have full read/write access to sysfs (for bind/unbind). Docker
+automatically pick free network port (``--publish-all``) for ability to connect
+over ssh. To be able to limit access to PCI bus, container is creating tmpfs
+mount type in PCI bus tree. CSIT reservation script is dynamically linking only
+PCI devices (NIC cards) that are reserved for particular container. This
+way it is not colliding with other containers. To make vfio work, access to
+``/dev/vfio`` must be granted.
+
+.. todo: Change default user to testuser with non-privileged and install sudo.
+
+Environment initialization
+--------------------------
+
+All 1-node servers are to be managed and provisioned via the [ansiblelink]_ set
+of playbooks with *vpp-device* role. Full playbooks can be found under
+[fdiocsitansible]_ directory. This way we are able to track all configuration
+changes of physical servers in gerrit (in structured yaml format) as well as we
+are able to extend *vpp-device* to additional servers with less effort or
+re-stage servers in case of failure.
+
+SR-IOV VF initialization is done via ``systemd`` service during host system boot
+up. Service with name *csit-initialize-vfs.service* is created under systemd
+system context (``/etc/systemd/system/``). By default service is calling
+``/usr/local/bin/csit-initialize-vfs.sh`` with single parameter:
+
+- **start**: Creates maximum number of :abbr:`virtual functions (VFs)` (detected
+ from ``sriov_totalvfs``) for each whitelisted PCI device.
+- **stop**: Removes all :abbr:`VFs` for all whitelisted PCI device.
+
+Service is considered active even when all of its processes exited successfully.
+Stopping service will automatically remove :abbr:`VFs`.
+
+::
+
+ [Unit]
+ Description=CSIT Initialize SR-IOV VFs
+ After=network.target
+
+ [Service]
+ Type=one-shot
+ RemainAfterExit=True
+ ExecStart=/usr/local/bin/csit-initialize-vfs.sh start
+ ExecStop=/usr/local/bin/csit-initialize-vfs.sh stop
+
+ [Install]
+ WantedBy=default.target
+
+Script is driven by two array variables ``pci_blacklist``/``pci_whitelist``.
+They MUST store all PCI addresses in **<domain>:<bus>:<device>.<func>** format,
+where:
+
+- **pci_blacklist**: PCI addresses to be skipped from :abbr:`VFs`
+ initialization (usefull for e.g. excluding management network interfaces).
+- **pci_whitelist**: PCI addresses to be included for :abbr:`VFs`
+ initialization.
+
+VF reservation
+--------------
+
+During topology initialization phase of script, mutex is used to avoid multiple
+instances of script to interact with each other during resources allocation.
+Mutal exclusion ensure that no two distinct instances of script will get same
+resource list.
+
+Reservation function reads the list of all available virtual function network
+devices in system:
+
+::
+
+ # Find the first ${device_count} number of available TG Linux network
+ # VF device names. Only allowed VF PCI IDs are filtered.
+ for netdev in ${tg_netdev[@]}
+ do
+ for netdev_path in $(grep -l "${pci_id}" \
+ /sys/class/net/${netdev}*/device/device \
+ 2> /dev/null)
+ do
+ if [[ ${#TG_NETDEVS[@]} -lt ${device_count} ]]; then
+ tg_netdev_name=$(dirname ${netdev_path})
+ tg_netdev_name=$(dirname ${tg_netdev_name})
+ TG_NETDEVS+=($(basename ${tg_netdev_name}))
+ else
+ break
+ fi
+ done
+ if [[ ${#TG_NETDEVS[@]} -eq ${device_count} ]]; then
+ break
+ fi
+ done
+
+Where ``${pci_id}`` is ID of white-listed VF PCI ID. For more information please
+see [pciids]_. This act as security constraint to prevent taking other unwanted
+interfaces.
+The output list of all VF network devices is split into two lists for TG and
+SUT side of connection. First two items from each TG or SUT network devices
+list are taken to expose directly to namespace of container. This can be done
+via commands:
+
+::
+
+ $ ip link set ${netdev} netns ${DCR_CPIDS[tg]}
+ $ ip link set ${netdev} netns ${DCR_CPIDS[dut1]}
+
+In this stage also symbolic links to PCI devices under sysfs bus directory tree
+are created in running containers. Once VF devices are assigned to container
+namespace and PCI deivces are linked to running containers and mutex is exited.
+Selected VF network device automatically dissapear from parent container
+namespace, so another instance of script will not find device under that
+namespace.
+
+Once Docker container exits, network device is returned back into parent
+namespace and can be reused.
+
+Network traffic isolation - Intel i40evf
+----------------------------------------
+
+In a virtualized environment, on Intel(R) Server Adapters that support SR-IOV,
+the virtual function (VF) may be subject to malicious behavior. Software-
+generated layer two frames, like IEEE 802.3x (link flow control), IEEE 802.1Qbb
+(priority based flow-control), and others of this type, are not expected and
+can throttle traffic between the host and the virtual switch, reducing
+performance. To resolve this issue, configure all SR-IOV enabled ports for
+VLAN tagging. This configuration allows unexpected, and potentially malicious,
+frames to be dropped. [inteli40e]_
+
+To configure VLAN tagging for the ports on an SR-IOV enabled adapter,
+use the following command. The VLAN configuration SHOULD be done
+before the VF driver is loaded or the VM is booted. [inteli40e]_
+
+::
+
+ $ ip link set dev <PF netdev id> vf <id> vlan <vlan id>
+
+For example, the following instructions will configure PF eth0 and
+the first VF on VLAN 10.
+
+::
+
+ $ ip link set dev eth0 vf 0 vlan 10
+
+VLAN Tag Packet Steering allows to send all packets with a specific VLAN tag to
+a particular SR-IOV virtual function (VF). Further, this feature allows to
+designate a particular VF as trusted, and allows that trusted VF to request
+selective promiscuous mode on the Physical Function (PF). [inteli40e]_
+
+To set a VF as trusted or untrusted, enter the following command in the
+Hypervisor:
+
+::
+
+ $ ip link set dev eth0 vf 1 trust [on|off]
+
+Once the VF is designated as trusted, use the following commands in the VM
+to set the VF to promiscuous mode. [inteli40e]_
+
+- For promiscuous all:
+ ::
+
+ $ ip link set eth2 promisc on
+
+- For promiscuous Multicast:
+ ::
+
+ $ ip link set eth2 allmulti on
+
+.. note::
+
+ By default, the ethtool priv-flag vf-true-promisc-support is set to
+ *off*, meaning that promiscuous mode for the VF will be limited. To set the
+ promiscuous mode for the VF to true promiscuous and allow the VF to see
+ all ingress traffic, use the following command.
+ $ ethtool set-priv-flags p261p1 vf-true-promisc-support on
+ The vf-true-promisc-support priv-flag does not enable promiscuous mode;
+ rather, it designates which type of promiscuous mode (limited or true)
+ you will get when you enable promiscuous mode using the ip link commands
+ above. Note that this is a global setting that affects the entire device.
+ However,the vf-true-promisc-support priv-flag is only exposed to the first
+ PF of the device. The PF remains in limited promiscuous mode (unless it
+ is in MFP mode) regardless of the vf-true-promisc-support setting.
+ [inteli40e]_
+
+Service described earlier *csit-initialize-vfs.service* is responsible for
+assigning 802.1Q vlan tagging to each vitual function via physical function
+from list of white-listed PCI addresses by following (simplified) code.
+
+::
+
+ SCRIPT_DIR="$(dirname $(readlink -e "${BASH_SOURCE[0]}"))"
+ source "${SCRIPT_DIR}/csit-initialize-vfs-data.sh"
+
+ # Initilize whitelisted NICs with maximum number of VFs.

+ # 802.1Q PF PCI address offset.
+ vlan_pf_off=$(( vlan_pf_idx * 100 + vlan_bs_off ))

-Abstract
---------
-
-FD.io VPP software data plane technology has become very popular across
-a wide range of VPP eco-system use cases, putting higher pressure on
-continuous verification of VPP software quality.
-
-This document describes a proposal for design and implementation of extended
-continuous VPP testing by extending existing test environments.
-Furthermore it describes and summarizes implementation details of Integration
-and System tests platform *1-Node VPP_Device*. It aims to provide a complete
-end-to-end view of *1-Node VPP_Device* environment in order to improve
-extendability and maintenance, under the guideline of VPP core team.
-
-The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD",
-"SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be
-interpreted as described in :rfc:`8174`.

-Physical Testbeds
------------------
-
-All :abbr:`FD.io (Fast Data Input/Ouput)` :abbr:`CSIT (Continuous System
-Integration and Testing)` vpp-device tests are executed on physical testbeds
-built with bare-metal servers hosted by :abbr:`LF (Linux Foundation)` FD.io
-project. Two 1-node testbed topologies are used:
-
-- **2-Container Topology**: Consisting of one Docker container acting as SUT
- (System Under Test) and one Docker container as TG (Traffic Generator), both
- connected in ring topology via physical NIC cross-connecting.
-
-Current FD.io production testbeds are built with servers based on one
-processor generation of Intel Xeons: Skylake (Platinum 8180). Testbeds built
-with servers based on Arm processors are in the process of being added to FD.io
-production.
-
-Following section describe existing production 1n-skx testbed.
-
-1-Node Xeon Skylake (1n-skx)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-1n-skx testbed is based on single SuperMicro SYS-7049GP-TRT server equipped with
-two Intel Xeon Skylake Platinum 8180 2.5 GHz 28 core processors. Physical
-testbed topology is depicted in a figure below.

-
-Server is populated with the following NIC models:
-
-#. NIC-1: x710-da4 4p10GE Intel.
-#. NIC-2: x710-da4 4p10GE Intel.
-
-All Intel Xeon Skylake servers run with Intel Hyper-Threading enabled,
-doubling the number of logical cores exposed to Linux, with 56 logical
-cores and 28 physical cores per processor socket.
-
-NIC interfaces are shared using Linux vfio_pci and VPP VF drivers:
-
-- DPDK VF driver,
-- Fortville AVF driver.
-
-Provided Intel x710-da4 4p10GE NICs support 32 VFs per interface, 128 per NIC.
-
-Complete 1n-skx testbeds specification is available on `CSIT LF Testbeds
-<https://wiki.fd.io/view/CSIT/Testbeds:_Xeon_Skx,_Arm,_Atom.>`_ wiki page.
-
-Total of two 1n-skx testbeds are in operation in FD.io labs.
-
-1-Node Virtualbox (1n-vbox)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-1n-skx testbed can run in single VirtualBox VM machine. This solution replaces
-the previously used Vagrant environment based on 3 VMs.
-
-VirtualBox VM MAY be created by Vagrant and MUST have additional 4 virtio NICs
-each pair attached to separate private networks to simulate back-to-back
-connections. It SHOULD be 82545EM device model (otherwise can be changed in
-boostrap scripts). Example of Vagrant configuration:
-
-::
-
- Vagrant.configure(2) do |c|
- c.vm.network "private_network", type: "dhcp", auto_config: false,
- virtualbox__intnet: "port1", nic_type: "82545EM"
- c.vm.network "private_network", type: "dhcp", auto_config: false,
- virtualbox__intnet: "port2", nic_type: "82545EM"
-
- c.vm.provider :virtualbox do |v|
- v.customize ["modifyvm", :id, "--nicpromisc2", "allow-all"]
- v.customize ["modifyvm", :id, "--nicpromisc3", "allow-all"]
- v.customize ["modifyvm", :id, "--nicpromisc4", "allow-all"]
- v.customize ["modifyvm", :id, "--nicpromisc5", "allow-all"]
-
-Vagrant VM is populated with the following NIC models:
-
-#. NIC-1: 82545EM Intel.
-#. NIC-2: 82545EM Intel.
-#. NIC-3: 82545EM Intel.
-#. NIC-4: 82545EM Intel.
-
-Containers
-----------
-
-It was agreed on :abbr:`TWS (Technical Work Stream)` call to continue with
-Ubuntu 18.04 LTS as a baseline system with OPTIONAL extend to Centos 7 and
-SuSE per demand [TWSLink]_.
-
-All :abbr:`DCR (Docker container)` images are REQUIRED to be hosted on Docker
-registry available from LF network, publicly available and trackable. For
-backup, tracking and contributing purposes all Dockerfiles (including files
-needed for building container) MUST be available and stored in [fdiocsitgerrit]_
-repository under appropriate folders. This allows the peer review process to be
-done for every change of infrastructure related to scope of this document.
-Currently only **csit-shim-dcr** and **csit-sut-dcr** containers will be stored
-and maintained under CSIT repository by CSIT contributors.
-
-At the time of designing solution described in this document the interconnection
-between [dockerhub]_ and [fdiocsitgerrit]_ for automated build purposes and
-image hosting cannot be established with the trust and respectful to
-security of FD.io project. Unless adressed, :abbr:`DCR` images will be placed in
-custom registry service [fdioregistry]_. Automated Jenkins jobs will be created
-in align of long term solution for container lifecycle and ability to build
-new version of docker images.
-
-In parallel, the effort is started to find the outsourced Docker registry
-service.
-
-Versioning
-~~~~~~~~~~
-
-As of initial version of vpp-device, we do have only single latest version of
-Docker image hosted on [dockerhub]_. This will be addressed as further
-improvement with proper semantic versioning.

-~~~~~~~~~~~~~~~~~
-
-This :abbr:`DCR` acts as the Jenkins slave (known also as jenkins minion). It
-can connect over SSH protocol to TCP port 6022 of **csit-shim-dcr** and executes
-non-interactive reservation script. Nomad is responsible for scheduling this
-container execution onto specific **1-Node VPP_Device** testbed. It executes
-:abbr:`CSIT` environment including :abbr:`CSIT` framework.
-
-All software dependencies including VPP/DPDK that are not present in
-**csit-sut-dcr** container image and/or needs to be compiled prior running on
-**csit-sut-dcr** SHOULD be compiled in this container.

-csit-shim-dcr
-~~~~~~~~~~~~~
-
-This :abbr:`DCR` acts as an intermediate layer running script responsible for
-orchestrating topologies under test and reservation. Responsible for managing VF
-resources and allocation to :abbr:`DUT (Device Under Test)`, :abbr:`TG
-(Traffic Generator)` containers. This MUST to be done on **csit-shim-dcr**.
-This image also acts as the generic reservation mechanics arbiter to make sure
-that only Y number of simulations are spawned on any given HW node.

-
-- *Initializing*: Container is initialized from within *Consul by HashiCorp*
- and *Nomad by HashiCorp*. Required docker parameters, to be able to run
- nested containers with VF reservation system are: privileged, net=host,
- pid=host.
-
-- *Connectivity*: Over SSH only, using <host>:6022 format. Currently using
- *root* user account as primary. From the jenkins slave it will be able to
- connect via env variable, since the jenkins slave doesn't actually know what

-csit-sut-dcr
-~~~~~~~~~~~~
-
-This :abbr:`DCR` acts as an :abbr:`SUT (System Under Test)`. Any :abbr:`DUT` or
-:abbr:`TG` application is installed there. It is RECOMMENDED to install DUT and
-all DUT dependencies via commands ``rpm -ihv`` on RedHat based OS or ``dpkg -i``
-on Debian based OS.
-
-Container is designed to be a very lightweight Docker image that only installs
-packages and execute binaries (previously built or downloaded on
-**jenkins-slave-dcr**) and contains libraries necessary to run CSIT framework
-including those required by DUT/TG.
-
-- *Container Image Location*: Docker image at snergster/csit-sut.

-Container required to run as ``--privileged`` due to ability to create nested
-containers and have full read/write access to sysfs (for bind/unbind). Docker
-automatically pick free network port (``--publish-all``) for ability to connect
-over ssh. To be able to limit access to PCI bus, container is creating tmpfs
-mount type in PCI bus tree. CSIT reservation script is dynamically linking only
-PCI devices (NIC cards) that are reserved for particular container. This
-way it is not colliding with other containers. To make vfio work, access to
-``/dev/vfio`` must be granted.
-
-.. todo: Change default user to testuser with non-privileged and install sudo.
-
-Environment initialization
---------------------------
-
-All 1-node servers are to be managed and provisioned via the [ansiblelink]_ set
-of playbooks with *vpp-device* role. Full playbooks can be found under
-[fdiocsitansible]_ directory. This way we are able to track all configuration
-changes of physical servers in gerrit (in structured yaml format) as well as we
-are able to extend *vpp-device* to additional servers with less effort or
-re-stage servers in case of failure.
-
-SR-IOV VF initialization is done via ``systemd`` service during host system boot
-up. Service with name *csit-initialize-vfs.service* is created under systemd
-system context (``/etc/systemd/system/``). By default service is calling
-``/usr/local/bin/csit-initialize-vfs.sh`` with single parameter:
-
-- **start**: Creates maximum number of :abbr:`virtual functions (VFs)` (detected
- from ``sriov_totalvfs``) for each whitelisted PCI device.
-- **stop**: Removes all :abbr:`VFs` for all whitelisted PCI device.
-
-Service is considered active even when all of its processes exited successfully.
-Stopping service will automatically remove :abbr:`VFs`.

-
-Script is driven by two array variables ``pci_blacklist``/``pci_whitelist``.
-They MUST store all PCI addresses in **<domain>:<bus>:<device>.<func>** format,
-where:
-
-- **pci_blacklist**: PCI addresses to be skipped from :abbr:`VFs`
- initialization (usefull for e.g. excluding management network interfaces).
-- **pci_whitelist**: PCI addresses to be included for :abbr:`VFs`
- initialization.
-
-VF reservation
---------------
-
-During topology initialization phase of script, mutex is used to avoid multiple
-instances of script to interact with each other during resources allocation.
-Mutal exclusion ensure that no two distinct instances of script will get same
-resource list.
-
-Reservation function reads the list of all available virtual function network
-devices in system:
-
-::
-
- net_path="/sys/bus/pci/devices/*/net/*"
-
- for netdev in \
- $(find ${net_path} -type d -name . -o -prune -exec basename '{}' ';');
- do
- if grep -q "${pci_id}" "/sys/class/net/${netdev}/device/device"; then
- # found VF
- fi
- done
-
-Where ``${pci_id}`` is ID of white-listed VF PCI ID. For more information please
-see [pciids]_. This act as security constraint to prevent taking other unwanted
-interfaces.
-The output list of all VF network devices is split into two lists for TG and
-SUT side of connection. First two items from each TG or SUT network devices
-list are taken to expose directly to namespace of container. This can be done
-via commands:
-
-::
-
- $ ip link set ${netdev} netns ${DCR_CPIDS[tg]}
- $ ip link set ${netdev} netns ${DCR_CPIDS[dut1]}
-
-In this stage also symbolic links to PCI devices under sysfs bus directory tree
-are created in running containers. Once VF devices are assigned to container
-namespace and PCI deivces are linked to running containers and mutex is exited.
-Selected VF network device automatically dissapear from parent container
-namespace, so another instance of script will not find device under that
-namespace.
-
-Once Docker container exits, network device is returned back into parent
-namespace and can be reused.
-
-Network traffic isolation - Intel i40evf
-----------------------------------------
-
-In a virtualized environment, on Intel(R) Server Adapters that support SR-IOV,
-the virtual function (VF) may be subject to malicious behavior. Software-
-generated layer two frames, like IEEE 802.3x (link flow control), IEEE 802.1Qbb
-(priority based flow-control), and others of this type, are not expected and
-can throttle traffic between the host and the virtual switch, reducing
-performance. To resolve this issue, configure all SR-IOV enabled ports for
-VLAN tagging. This configuration allows unexpected, and potentially malicious,
-frames to be dropped. [inteli40e]_
-
-To configure VLAN tagging for the ports on an SR-IOV enabled adapter,
-use the following command. The VLAN configuration SHOULD be done
-before the VF driver is loaded or the VM is booted. [inteli40e]_
-
-::
-
- $ ip link set dev <PF netdev id> vf <id> vlan <vlan id>
-
-For example, the following instructions will configure PF eth0 and
-the first VF on VLAN 10.
-
-::
-
- $ ip link set dev eth0 vf 0 vlan 10
-
-VLAN Tag Packet Steering allows to send all packets with a specific VLAN tag to
-a particular SR-IOV virtual function (VF). Further, this feature allows to
-designate a particular VF as trusted, and allows that trusted VF to request
-selective promiscuous mode on the Physical Function (PF). [inteli40e]_
-
-To set a VF as trusted or untrusted, enter the following command in the
-Hypervisor:
-
-::
-
- $ ip link set dev eth0 vf 1 trust [on|off]
-
-Once the VF is designated as trusted, use the following commands in the VM
-to set the VF to promiscuous mode. [inteli40e]_
-
-- For promiscuous all:
- ::
-
- $ ip link set eth2 promisc on
-
-- For promiscuous Multicast:
- ::
-
- $ ip link set eth2 allmulti on
-
-.. note::
-
- By default, the ethtool priv-flag vf-true-promisc-support is set to
- *off*, meaning that promiscuous mode for the VF will be limited. To set the
- promiscuous mode for the VF to true promiscuous and allow the VF to see
- all ingress traffic, use the following command.
- $ ethtool set-priv-flags p261p1 vf-true-promisc-support on
- The vf-true-promisc-support priv-flag does not enable promiscuous mode;
- rather, it designates which type of promiscuous mode (limited or true)
- you will get when you enable promiscuous mode using the ip link commands
- above. Note that this is a global setting that affects the entire device.
- However,the vf-true-promisc-support priv-flag is only exposed to the first
- PF of the device. The PF remains in limited promiscuous mode (unless it
- is in MFP mode) regardless of the vf-true-promisc-support setting.
- [inteli40e]_
-
-Service described earlier *csit-initialize-vfs.service* is responsible for
-assigning 802.1Q vlan tagging to each vitual function via physical function
-from list of white-listed PCI addresses by following (simplified) code.
-
-::
-
- pci_idx=0
- for pci_addr in ${pci_whitelist[@]}; do
- pci_path="/sys/bus/pci/devices/${pci_addr}"
- pf=$(basename "${pci_path}"/net/*)
- for vf in $(seq "${sriov_totalvfs}"); do
- # PCI address index in array (pairing siblings).
- vlan_pf_idx=$(( pci_idx % (${#pci_whitelist[@]} / 2) ))
- # 802.1Q base offset.
- vlan_bs_off=1100
- # 802.1Q PF PCI address offset.
- vlan_pf_off=$(( vlan_pf_idx * 100 + vlan_bs_off ))
- # 802.1Q VF PCI address offset.
- vlan_vf_off=$(( vlan_pf_off + vf - 1 ))
- # VLAN string.
- vlan_str="vlan ${vlan_vf_off}"
- # MAC string.
- mac5="$(printf '%x' ${pci_idx})"
- mac6="$(printf '%x' $(( vf - 1 )))"
- mac_str="mac ba:dc:0f:fe:${mac5}:${mac6}"
- # Set 802.1Q VLAN id and MAC address
- ip link set ${pf} vf $(( vf - 1 )) ${mac_str} ${vlan_str}
- ip link set ${pf} vf $(( vf - 1 )) trust on
- ip link set ${pf} vf $(( vf - 1 )) spoof off
- done
- pci_idx=$(( pci_idx + 1 ))
- done
-
-Assignment starts at VLAN 1100 and incrementing by 1 for each VF and by 100 for
-each white-listed PCI address up to the middle of the PCI list. Second half of
-the lists is assumed to be directly (cable) paired siblings and assigned with
-same 802.1Q VLANs as its siblings.
