There are a number of ways a control plane can (or could) integrate with VPP.
Which one is most suitable for you depends.

1) Mirror interfaces. As described in https://wiki.fd.io/view/VPP_Sandbox/router
Each VPP interface is mirrored as a Linux TAP interface. Any traffic destined 
to an interface address in VPP is forwarded to the TAP interface.
Any packet received on the TAP interface is shipped out the physical interface.
All Linux tools and applications work unchanged. Including use of raw sockets.
A all or nothing approach. And might not be suitable for cases with lots of 
(virtual) interfaces.

2) Separate punt interface. Transport using memif and/or Unix domain socket.
Control plane registeres with VPP which protoocols it wants. E.g. a DHCP server 
registeres for UDP port 69,
an IPv6 ND daemon registres for a set of ICMPv6 types.
Raw packets sent over transport with meta data. Likewise when CP sends packet, 
it includes meta-data to specify outgoing interface and/or VPP processing graph 
node.
See https://git.fd.io/vpp/tree/src/vnet/ip/punt.h#n44
This is currently only used by https://pypi.org/project/dhcpkit-vpp/
Gaps:
 - Missing selectors (only UDP supported)
 - Missing transports (only UDS)
 - Missing throttling and QoS

3) Integrate with VPP host stack.
For TCP VPP exposes an API that control plane applications can use.
I plan to put a Python wrapper on top of VCL and integrate with exaBGP.
This approach is of course limited to whatever VCL supports.
But in theory VCL could give a full socket-like API.

4) Integrated in VPP
Write the control plane functions as VPP plugins.
This is how ND, ARP, DHCP and a few others are done.

Any others?

Personally I would like to do more work on 2.
What’s your view?

Best regards,
Ole

[vpp-dev] how to set cb for keepalive of vapi-connection @ 18.10

2018-11-12 Thread wangchuan...@163.com

Hi，
At vpp stable/18.10, using vapi_connect to connect vpp and set the "bool 
handle_keepalives " to true,
But how can i add the cb for keepalives?
If do, does it means that I could judge the timespan to found the disconnection 
, and need to reconnect using vapi_disconnect & vpai_connect ?

Thanks !

Re: [vpp-dev] inet raw socket

2018-11-12 Thread saint_sun 孙 via Lists . Fd . Io

hello Ole,
yes, we have a control plane, and the protocols I mentioned below run in the 
control plane. 
when these protocols want to send packets, they organize their own protocol 
data then call inet raw socket to set the IP header and link header. when 
received a packet from the interface, first we will stripe the link header and 
ip header then hand over to the corresponding modules through inet raw socket. 
Now can you know what I want to do?

You are still leaving me guessing at what you are trying to do.

You can implement these inside of VPP, where you obviously don’t need or use a 
socket API.

Sounds like you are talking about having these protocols implemented on the 
control plane side.
There are many ways of integrating a control plane with VPP.
With e.g. a port mirroring approach, you would use Linux applications 
unchanged. That’s not necessarily where I would go. We have some ideas around 
improvements for the CP/DP interface, and I’m happy to engage in a discussion 
with that, but you would have to share what problem you are trying to solve in 
more detail.

audience of very knowledgeable and highly technical, free and open 
source software activists.


**Topics:**

This year the DevRoom topics will include the following Software Defined 
Networking fields.


- Infrastructure: virtual switches & routers, routing daemons, firewall, 
security, etc.
- Virtual Network Functions: open source network functions, user-space 
networking stacks, kernel-space networking innovations.
- Tooling: Networking SDK's, libraries, frameworks, debuggers, counters 
& statistics, domain specific languages & extensions, etc.

- Validation: Testing tools & frameworks, traffic generators etc
- Orchestration: NFV management, ML2 plugins, CNI plugins, SDN 
Controllers, etc.


This year, the DevRoom will focus on low-level networking and high 
performance packet processing, network automation of containers, virtual 
machines and private cloud, and the management of networking 
applications to maintain very high availability and performance 
independent of whatever the world can throw at their infrastructure 
(datacenter outages, fires, broken servers, you name it).


The deadline for submissions is November 25th, 2018. FOSDEM will be held 
on the weekend of February 2-3, 2019 and the Software Defined Networking 
DevRoom will take place on Saturday, February 2, 2019.


See http://mdr78.github.io/fosdem/2018/10/15/fosdem-2019-cfp.html for 
how for more information, including how to submit a proposal.


As you know FOSDEM has zero marketing budget, we would be grateful if

Hi,

A developer in my team has suggested a fix in memory_vlib.c (VPP 18.01), I am 
attaching the base and modified file. This is related to dead client scan.

At a high level, the fix seems to be doing some additional cleanup when a dead 
client is detected. The intention is not to leak the memory over the shared 
memory interface.
Unfortunately I am not very intimately familiar with the mechanics of the data 
structures here, so if some experts in this area can do a diff of the attached 
files and advise me if the fix makes any sense, that will be really great.

Re: [vpp-dev] [csit-dev] new per-patch job

2018-11-12 Thread Vratko Polak -X (vrpolak - PANTHEON TECHNOLOGIES at Cisco) via Lists.Fd.Io


Hello VPP devs.

Now that CSIT testbeds are not as busy
running tests for 1810 release report,
you can give the per-patch performance job a try again.

The job can still be used as announced (see below),
but the internal logic has been tweaked.
Good news: False regressions should be much less frequent now.
Bad news: One run takes 90-100 minutes (not counting queueing time).

The job still gets the following comment on failure:
  No problems were identified. If you know why this problem occurred,
 please add a suitable Cause for it.
How can I add a Cause to distinguish "Regression has been detected"
from other (rare but still possible) failures?

By the way, while testing with [0]
I have confirmed that the previously merged [1]
causes (some of) the regressions seen in trending.
Unfortunately, the changes merged in the meantime
make it hard to revert it.

Original plan was to have the job non-voting.
First implementation has left the voting active by accident,
now it is switched to non-voting (also by accident).

Non-voting is safer, we can be sure result of this job
does not override possible -1 from other verify jobs.

Subject: [vpp-dev] new per-patch job

Hello VPP devs.

There is a new way of testing performance impact
of a VPP Change before merging it.

When you add Gerrit comment "perftest"
a job will start (different from the previously available one).
It will compile both the code in the Change and in its parent,
run few tests against both builds,
and vote -1 if a regression is detected.

The job takes around one hour to finish (similar to virl job),
mostly spent by compiling.

The job compares results of 4 tests by default:
ip4base, ip6base, l2bdbasemaclrn and l2xcbase.

The job supports tag selection
(the same way as the previous job).

The job is using 2-node skylake testbeds,
so some tests are not available
(e.g. the ones related to encapsulation).

The regressions are detected
using the same algorithm as in trending graphs,
but the result is not 100% reliable.
Sometimes, even running the same build twice
shows statistically significant difference in performance.

Going forward, there are three main areas for improvements:

1. Add more tests (to the set executed by default).
This would find more kinds of performance regressions.

2. Make the job run faster. Some kind of artifact caching
could be implemented, possibly using packagecloud.

3. Make the vote more reliable. Either by identifying
and fixing the current causes of performance differences,
or at least by working around them (somehow).

So please, give the new job a try,
and tell us which area of improvement to focus on.

Vratko (and CSIT team).
