freebsd-vpc's Issues

Convert vpc.ID.Node's type to be net.HardwareAddr

Convert vpc.ID's Node attribute to be of type net.HardwareAddr. This is purely for type safety. A net.HardwareAddr is a [6]byte under the hood.

Add `vpc mux disconnect` command

Add `vpc ethlink connect` command

Decompose vpc switch port add into:

vpc ethlink create
vpc ethlink connect

`vpc_ctl(2)` `GET_FEATURES` meta operation

We need some way of querying vpc(4) to see what features are supported. I would suggest an extensible bit flag system, like:

n := vpc_ctl(..., GET_FEATURE_SIZE,...);
buf := [n]byte
n := vpc_ctl(..., GET_FEATURE_FLAGS, NULL, NULL, n, &buf);

Or something ascii where buf is a newline delimited list of features in the form of:

feature:switch.add=1
feature:switch.del=1
feature:vpcp.add=1

And this could just be a const char* in the kernel someplace.

Revise VPC IDs for Ports to match LLDP spec

It would be nice if the VPC ID for a Port ID mapped cleanly into LLDP TLVs.

Right now VPC IDs for vpcps are random and don't retain any mention of the Chassis ID. Unlike a vmnic, a vpcp belongs to a vpcsw and can not be moved between different vpcsw devices. A vpcp's VPC ID should therefore contain a hint of the parent vpcsw so that there is some semantic equivilance with hardware switches and discoverability via tools/protocols such as LLDP.

It's not high priority and it is unclear how to make this happen without using bits above the Node in a VPC ID.

https://en.wikipedia.org/wiki/Link_Layer_Discovery_Protocol

WTB the last 24bits or first 24bits of the UUID to match the Port ID TLV from LLDP.

`vagrant up` failures: first on "jen20/FreeBSD-12.0-CURRENT-VPC" private(?) box, then on "connect failed" in "compile" vm

First attempt after having installed the prereqs mentioned in the README.md:

URL and error message are shown below:

VM, run `vagrant status NAME`.

vpc vm destroy

Document the ability to spin up test VMs

`vpc_ctl(2)` `GET_ID` meta op

Given a vpc descriptor, it should be possible to query the VPC ID of the descriptor.

Add `vpc mux ft set` command

Add `vpc mux create` command

how is "joyent/FreeBSD-12.0-CURRENT-VPC" built?

https://app.vagrantup.com/joyent/boxes/FreeBSD-12.0-CURRENT-VPC

How is that image built? Sean and Sam didn't know. For example, if (for starters) I wanted to update /home/vagrant/.profile like so:

[vagrant@freebsd-compile ~]$ diff -u .profile.bak .profile
--- .profile.bak	2018-03-16 18:51:59.288037000 +0000

How would I go about doing that and getting a new image?

Ensure guest queue count

In the guest we need to set the number of queues. On the CLI the command is:

ethtool -L enp0s6 combined <nqueues>

and you verify with:

ethtool -l enp0s6

On a memory-bound system this is the difference between 56Gbps for the guest and 65Gbps for the guest.

Tab-completion for VPC ID support

Tab completion already works, however it only works for verbs and argument names, not argument values. When tab completing a VPC ID, the UUID needs to be looked up and completed using a prefix search. i.e.

# vpc list -t vpcsw
 TYPE   ID                                    UNIT NAME 
 vpcsw  da64c3f3-095d-91e5-df01-5aabcfc52468  vpcsw0    

  TOTAL                   1                               
# vpc sw destroy --switch-id=da[tab]

Should work.

`vpc console` subcommand

You shouldn't have to lookup the nmdm(4) device name to attach to it via cu(1).

Add `vpc switch port set` command

Debug `flow-id` for TX

flow-id is disabled atm. It's not required for the performance we're getting atm, but it would be good to figure out why we need to have this disabled.

Duplicate `vpcp` adds permissible in VPC switch

It is possible to re-add the same vpcp to a vpcsw. Both a vpcp needs to prevent reuse (pretty certain this is the case now) and the vpcsw needs to ensure uniqueness for all vpcps added to itself.

This issue can be closed if a vpcp can only be assigned to a vpcsw and can not be reused. At present vpcps are created by the vpcsw however this is going to be broken out so that a vpcp's lifecycle is independent of a vpcsw.

`vpc ssh` subcommand

Add `vpc mux` subcommand

Implicitly "commit" an object when it is plugged into a switch

When a vpcp is plugged into a vpcsw or a vmnic is added to a vpcp, implicitly commit/freeze the object in question and move its internal state to an immutable state.

Add `vpc destroy` hidden command

Useful for iterating

Add MPLSLink interface

This came up in conversation with someone at AsiaBSD who was interested in being able to use vpc(4) to participate in MPLS networks. I never thought about this before, but we could bridge between vpc(4) and MPLS networks using hosts that spanned the two encapsulation technologies in order to bridge VPC hosts across MPLS virtualized circuits.

I'm putting this on the back-burner as a really clever idea that someone else can implement.

vpc vm create

Expand test coverage via `go test -cover`

Expand test coverage to >=30%
Expand test coverage to >=50%
Expand test coverage to >=75%
Expand test coverage to >= 90%
Integrate testing into CI

Add regression testing for CI

When running CI testing, two or more hosts should be spun up and perform basic regression testing between the two hosts. Tests should include:

iperf benchmarking with low-watermark alarms
cat random-file | nc && md5 verification for stream integrity checking
