What is Network Service Mesh

Network Service Mesh (NSM) is the Hybrid/Multi-cloud IP Service Mesh.

cmd-forwarder-sriov's Issues

Add initial abstract forwarder application

Add interface injection chain element

Add chain element that injects given VF network interface into the cleint's pod network namespace.
Provided parameters in NetworkServiceRequest.MechanismPreferences.Parameters map:
netnsInode - inode for client's pod network namespace file in /proc/<pid>/net/ns
vfInterfaceName - target interface name

Add retries for the method of device plugin ListAndWatch()

Motivation

In the current implementation, if device plugin server is busy/unavailable for some period then the device plugin stops listen to resources. In this case, to fix the problem user will need to do re-deploy... To avoid this kind of issue we need to add re-tries as we have in monorepo.

Spec: SR-IOV forwarder Device Plugin

User configures Forwarder with the list of PF -> service matches.

0000:00:01.0:
  capabilities:
  - intel
  - 10G
  services:
  - serv.dom.a
  - serv.dom.b
0000:00:02.0:
  capabilities:
  - mlx5
  - 10G
  services:
  - serv.dom.b
  - serv.dom.c

Forwarder creates all available VFs for the given PFs and generates tokens.

0000:00:01.0 -> 32 VF -> 32 * { serv.dom.a/intel, serv.dom.a/10G, serv.dom.b/intel, serv.dom.b/10G }
0000:00:02.0 -> 16 VF -> 16 * { serv.dom.b/mlx5, serv.dom.b/10G, serv.dom.c/mlx5, serv.dom.c/10G }

Total:
- 32 * serv.dom.a/intel
- 32 * serv.dom.a/10G
- 32 * serv.dom.b/intel
- 16 * serv.dom.b/mlx5
- 48 * serv.dom.b/10G
- 16 * serv.dom.c/mlx5
- 16 * serv.dom.c/10G

In the terms of Device Plugin - token is a device. Forwarder advertise tokens. In the beginning all tokens are in free state.
Client pod requests tokens.

resources:
  limits:
    serv.dom.a/intel: "1"
    serv.dom.b/10G: "1"

Device Plugin selects 2 tokens for the client, sets them in allocated state and injects theirs IDs into the Client pod via environment variables.

NSM_SRIOV_TOKENS=serv.dom.a/intel:c2024bf1,serv.dom.b/10G:ad6167d6

Client requests connection using token ID.

Request.MechanismPreferences = []{
    {
        Cls: cls.LOCAL,
        Type: vfio.MECHANISM,
        Parameters: {
            tokenID: "ad6167d6",
        },
    },
}

Forwarder filters available PFs by token and selects VF for the connection. For the selected VF Forwarder sets passed token in in use state and sets 1 token for the other supported by VF token types in closed state and marks them as unhealthy for the Device Plugin. Tokens to become closed first are selected from the free tokens, if there is no free, tokens are selected from the allocated tokens.

token: service-b/10G{ad6167d6}
PFs supported:
- 0000:00:01.0
- 0000:00:02.0
VF selected: 0000:00:02.4
token state changes:
- serv.dom.b/10G{ad6167d6} -> in use
- serv.dom.b/mlx5{b6ce9dc3} -> closed + unhealthy
- serv.dom.c/mlx5{a529b8ef} -> closed + unhealthy
- serv.dom.c/10G{5fbffeb4} -> closed + unhealthy

When client closes connection, in use token becomes allocated and all related closed tokens become free and healthy for the Device Plugin.
When client disconnects from the Forwarder, allocated token becomes free.

Add initial docker file

Add test Endpoint

Add test Endpoint which accepts Request with the following parameters

1. Connection.NetworkService - the name of the requested network service
2. Request.MechanismPreferences[].PCIAddress - each Mechanism(Kernel or VFIO) in MechanismPreferences has PCIAddress field that contains PCI address of physical function that is available on the Forwarder.

Endpoint selects one of the provided PCI addresses in the availablePorts and returns Connection with the following parameters:

1. Mechanism.PCIAddress - selected PCIAddress.

Endpoint config example

resources:
-  res1:
    networkServiceName: service1.example.com
    sourceHostName: example.org
    sourcePCIAddress: 0000:01:00:0
    capability: 10G
    targetMACAddress: 00:0a:95:9d:68:16
-  res 2:
    networkServiceName: service2.example.com
    sourceHostName: example.org
    sourcePCIAddress: 0000:02:00:0
    capability: 100G
    targetMACAddress: 00:1b:44:11:3a:b7

Add initial forwarder config initialization

Add initial CI for cmd-forwarder-sriov repository

move device plugin server into common repo

Can we move device plugin server implementation into a common repo like sdk-k8s or sdk-sriov so that it can also be reused by ovs forwarder (going to get implemented) that has support for smartnic based VFs.
The forwarder just have to rely this StartServers API to start the device plugin server with required token pools based on the sriov.conf file.

Add VF selector chain element

Add chain element that will select one from virtual functions across all available NICs based on next info:

1. Returned endpointPortMacAddress returned by eNSMgr in NetworkServiceRequest.MechanismPreferences.Parameters map
2. Forwarder config, containing info about which PF is connected to which server port
3. list of VFs associated with each PF

This chain element has to add vfInterfaceName parameter containing interface name to NetworkServiceRequest.MechanismPreferences.Parameters map

Move all tests to separate testing pkg

Motivation

We are not using white-box testing in newly styled NSM repositories. So then we should move all tests to separate pkgs and make sure that we are not testing private states

https://github.com/networkservicemesh/cmd-forwarder-sriov/blob/master/local/sdk-sriov/pkg/k8s/manager_test.go#L17

mechanism preferences doesn't work when nsc and nse are in same worker node

icmp responder nse throws the following error cannot support any of the requested mechanism when sriov forwarder sends service request with {"mechanism_preferences":{"+0":{"cls":"REMOTE","type":"NOOP"}}} (is the cls parameter valid when nsc and nse are in the same worker node ?)

Steps to reproduce:

Running this example on a single node k8s cluster.

Testing application test/applications/k8s can be removed

Actually application https://github.com/networkservicemesh/cmd-forwarder-sriov/blob/master/test/applications/k8s/main.go can be removed.

Motivation

We can use a stub of k8s/kubeadm server and use the real cmd-forwarder-sriov application. In this case, we'll test the real application. Currently, we are testing some testing stub...

Remove redundant test API

Motivation

https://github.com/networkservicemesh/cmd-forwarder-sriov/blob/master/test/tools/channel.go

It looks like test/tools/channel actually is not needed because all selects can be used inside the test as we do this mostly in each of our SDK tests.

NOTE: Using select in the test is a natural approach for golang.

Apply pattern for cmd repositories
