They don’t. If I recall correctly fragmentation is done in ip4-rewrite, and 
that’s were fragments end up after a trip by ip4-frag. 

Packet trace is your friend here. 

(trace add  
Send large packet

[vpp-dev] FW: [openstack-dev] networking-vpp 18.10 for VPP 18.10 is now available

[Jerome Tollet via Lists.Fd.Io]

Dear VPP’ers,
This message may be of interest to you.

Répondre à : "OpenStack Development Mailing List (not for usage questions)" 

Date : jeudi 8 novembre 2018 à 23:05
À : openstack-dev 
Objet : [openstack-dev] networking-vpp 18.10 for VPP 18.10 is now available

Hello All,

In conjunction with the release of VPP 18.10, we'd like to invite you all to 
try out networking-vpp 18.10 for VPP 18.10.
As many of you may already know, VPP is a fast user space forwarder based on 
the DPDK toolkit. VPP uses vector packet
processing algorithms to minimize the CPU time spent on each packet to maximize 
throughput.

Networking-vpp is a ML2 mechanism driver that controls VPP on your control and 
compute hosts to provide fast L2 forwarding
under Neutron.

In this release, we have made improvements to fully support the network trunk 
service plugin. Using this plugin, you can attach
multiple networks to an instance by binding it to a single vhostuser trunk 
port. The APIs are the same as the OpenStack Neutron trunk
service APIs. You can also now bind and unbind subports to a bound network 
trunk.

Another feature we have improved in this release is the Tap-as-a-service(TaaS). 
The TaaS code has been updated to handle any out of order
etcd messages received during agent restarts. You can use this service to 
create remote port mirroring capability for tenant virtual networks.

Besides the above, this release also has several bug fixes, VPP 18.10 API 
compatibility and stability related improvements.

The README [1] explains how you can try out VPP using devstack: the devstack 
plugin will deploy the mechanism driver and VPP 18.10
and should give you a working system with a minimum of hassle.

We will be continuing our development between now and VPP's 19.01 release. 
There are several features we're planning to work on
and we will keep you updated through our bugs list [2]. We welcome anyone who 
would like to come help us.

Everyone is welcome to join our biweekly IRC meetings, every other Monday (the 
next one is due this Monday at 0800 PT = 1600 GMT.

Re: [vpp-dev] #vpp sctp echo test crash

[Florin Coras]

Hm, I suspect in case of TCP it may be an overlap between unit tests and the 
throughput test. I’ve separated them here. Can you try it out with 500M 
locally? It works fine on my box, but maybe it has to do with the hardware it 
runs on. 

Thanks, 
Florin

Re: [vpp-dev] #vpp sctp echo test crash

[Marco Varlese]

It finishes with errors (stating 3 tests failed). Same behavior as seen with 
SCTP so I'm now guessing that's rather an issue with the test code (either 
client or server) or with the session layer (doubt that since VCL works)??
Thoughts?

Re: [vpp-dev] #vpp sctp echo test crash

[Florin Coras]

Hi Marco, 

So echo test with 500MB does finish and reports throughput after 15s but with 
warnings of the type “clients stuck”?

Note that we also have tests that run iperf3 for about 5s and those exchange GB 
of data probably.

 Hi Macro,
  
 I’m running on master branch and latest version.
  
 “make test TEST-test_sctp.py” also works for me. I want to benchmark the 
 performance of sctp, but fifo-size is only 4 in test_sctp.py, so the 
 throughput is only ~2Gbps. If I increase the fifo-size in test_sctp.py, 
 then the test fails.

 That’s why I want to use CLI commands to test SCTP. I’m not intended to

 Dear Yao,
  
 First of all, are you on MASTER branch or some other release?
  
 Second, can you run "make test TEST=test_sctp.py" and see if that works 
 for you? It all looks good on my side and on Jenkins.
  
 If you are interested in running multiple clients, you can do that by 
 editing test_sctp.py and add "nclients X" (where X can be 2 or more).
  
 Again, I have just tested it right now and I cannot see that issue.
  
  
 Cheers,
 Marco

Re: [vpp-dev] #vpp sctp echo test crash

[Marco Varlese]

Well, folks there's something strange here...
I was trying to understand what's going on with SCTP and (because I couldn't see
the light) I decided to give TCP a try.
I hence modified test_tcp.py to have 500 mbytes to send and the test fails.
Similarly to what happens for SCTP. I did try to increase the test-timeout but
without much success...
Interestingly, for both TCP and SCTP, with a test-timeout of 30 seconds the test
completes (with errors) after round 12-15 secs...

Re: [vpp-dev] Regarding IP Fragmentation

[Prashant Upadhyaya]

Hi Ole,

Thanks for the information.

Suppose my IP datagram gets fragmented into fragments F.1 and F.2, do
these again get submitted to ip4-input ?
I am trying to figure out the path in the graph from the time I submit
my v4 IP datagram to ip4-lookup.
What is crucial for me to know is if the fragments do land up at
ip4-input or not.

Regards
-Prashant

Yes, if IPv4 and DF==0. 
And you better remember that IP fragments are almost never a good idea.

[vpp-dev] Regarding IP Fragmentation

[Prashant Upadhyaya]

Hi,

If I hand-construct an IP datagram (bigger than mtu) using chained
vlib buffers and send this chain to ip4-lookup, would that be
fragmented and sent out as per the mtu requirements of the interface
from which the packet is determined to be sent out ? (assume that the
rx and tx sw_if_index is properly set)

If not, which node do I send this datagram to, to achieve effectively
the above ?

Regards

Re: [vpp-dev] #vpp sctp echo test crash

[Florin Coras]

Hi guys, 

I unfortunately missed this. Yes, the fifo size provided is the number of kB 
and yes you should be able to do 4MB (fifo-size 4096) or even higher. 

The “stuck clients” warning is just a notification, the test can still finish. 
To make sure you give the test enough time, add “test-timeout 
” to the list of parameters.

Hi all,

Some guys are asking for the original code in private.
Here is our answer:


We are working on reworking the original code, and doing internal legal review.

When it is done,  we will submit the code to FD.io community for IPR review in 
one or two weeks.

Please see:
src/vnet/session-apps/echo_client.c
src/vnet/session-apps/echo_server.c

In there you would see that fifo-size is shifted left by 10 (that means 4
becomes 4096). Maybe you want to try with 8 or 16?
Hopefully, Florin can shed some light about the usage of 4096 for the fifo-
size... which would eventually mean a fifo of 4M entries?

I am not sure why you see nclients=2 in test_sctp.py... there's no mention of it
on latest MASTER...

Hello, 

I want to use the latest VPP, instead of 17.10. The latest ( 18.10 ) version 
pppoe plugin is not working correctly. 

The PADI packets are successfully sent to the cp interface, but it is not

Re: [vpp-dev] #vpp sctp echo test crash

[Yao, Chengqiang]

Hi Macro,

I’m running on master branch and latest version.

“make test TEST-test_sctp.py” also works for me. I want to benchmark the 
performance of sctp, but fifo-size is only 4 in test_sctp.py, so the throughput 
is only ~2Gbps. If I increase the fifo-size in test_sctp.py, then the test 
fails.
That’s why I want to use CLI commands to test SCTP. I’m not intended to run 
multiple clients, the reason I set nclients=2 is because test_sctp.py does the 
same thing, I just want to keep the same.

You mean you use the same commands in my last mail, and there is no issue? If 
yes, then I need to check my setup.



Best Regards,
Chengqiang Yao

Dear Yao,

First of all, are you on MASTER branch or some other release?

Second, can you run "make test TEST=test_sctp.py" and see if that works for 
you? It all looks good on my side and on Jenkins.

If you are interested in running multiple clients, you can do that by editing 
test_sctp.py and add "nclients X" (where X can be 2 or more).

Again, I have just tested it right now and I cannot see that issue.


Cheers,
Marco

Hi Yao,

As per test_sctp.py the command is:

test echo server appns 0 fifo-size 4 [URI]

Where URI is made up as: sctp://IP/PORT

Please, take a look at "test/test_sctp.py" to see also the client side of it.

Is there any sample code to show how to use SCTP (such as association, packet 
transmission/reception, etc.)? And is there any performance report for SCTP?
You can have a look at the test for SCTP:
1) test/test_sctp.py
2) src/vnet/session-apps/echo_client.c & echo_server.c

The echo_client and echo_server are used by TCP / UDP and SCTP to exercise the 
networking stack implemented.

With regards to the state-machine (I assumed that's what you're asking by 
"association", "packet transmssion/reception", etc.), the whole of it is gone 
through when running the tests.
If you are interested in seeing/learning how that's implemented I am afraid you 
need to look into the code tho.

Re: [vpp-dev] PPPoE plugin documentation/support

Still waiting on this. 
Can anyone help me on this one?

Hello, 

I want to use the latest VPP, instead of 17.10. The latest ( 18.10 ) version
pppoe plugin is not working correctly. 

The PADI packets are successfully sent to the cp interface, but it is not
creating and pppoe fib, due to which the PADO packets are being dropped.

Packet 1

02:34:23:456994: virtio-input
  virtio: hw_if_index 3 next-index 4 vring 0 len 63
hdr: flags 0x00 gso_type 0x00 hdr_len 0 gso_size 0 csum_start 0
csum_offset 0 num_buffers 1

  PPPOE_DISCOVERY: e6:b1:bd:65:91:c1 -> 52:54:00:79:64:b9
02:34:23:457031: error-drop
  ethernet-input: l3 mac mismatch

vpp# show pppoe fib
no pppoe fib entries

Is this behavior intentional? Do I need to configure anything else other
than the cp interface?

Its working fine with VPP 17.10. I can see that a pppoe fib is created as
soon as the 1st PADI request arrives, which sets up the reverse path.
However, in VPP 18.07 & 18.10 there is no fib entry created and the PADO
packets are being dropped. 

The slides don't show a trace for the PADO replies.

Dear Hongjun, 

I was able to correctly set up the cp interface, my mistake as I was giving
the wrong interface index. 
Now the PADI packets are passed to cp interface. 

I started a pppoe-server on the Linux side (tap0) interface, but VPP is
dropping the PADO packets. 
Adding a trace on the virtio-input shows this: 

00:04:07:498195: virtio-input
  virtio: hw_if_index 2 next-index 4 vring 0 len 71
hdr: flags 0x00 gso_type 0x00 hdr_len 0 gso_size 0 csum_start 0
csum_offset 0 num_buffers 1
00:04:07:498204: ethernet-input
  PPPOE_DISCOVERY: f6:a0:85:84:98:e6 -> 3c:fd:fe:25:e6:20
00:04:07:498209: error-drop
  ethernet-input: l3 mac mismatch

The destination MAC address belongs to the pppoe-client, that's connected to
the 10G interface. However, VPP doesn't seem to know where to forward the
PADO replies. 
Also there are no entries in the pppoe fib for this client. Can you please
help me with this one? Please let me know if you need any more information. 

Regards,
Alp Arslan

Hi Alp Arslan,

To make tap_cli work, you need to revert the code as per this patch:

Dear Hongjun, 

Thanks for the reply. 

I am using the VPP version 18.07. If the tap_cli is still present, can you
please point me towards what could be the problem with the existing plugin. 
I would like to see this one working a little bit, before starting to look
into tapv2.

Hi Alp Arslan,

Since tap_cli code is going to be deprecated in favour of tapv2.
I suggest you leverage tapv2, and also need some rework for PPPoE plugin.

Re: [vpp-dev] inet raw socket

[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?

Re: [vpp-dev] #vpp sctp echo test crash

Hi Macro,

I follow test_sctp.py to use following commands in server and client, but 
client can not connect server with an error printed “echo_client_node_fn:238: 
stuck clients” as you can see below.
Do I miss any command ?

As per test_sctp.py the command is:

Where URI is made up as: sctp://IP/PORT

Please, take a look at "test/test_sctp.py" to see also the client side of it.

After debugging, I found it’s caused by invalid sw_if_index in

You can have a look at the test for SCTP:
1) test/test_sctp.py
2) src/vnet/session-apps/echo_client.c & echo_server.c

The echo_client and echo_server are used by TCP / UDP and SCTP to exercise the 
networking stack implemented.

With regards to the state-machine (I assumed that's what you're asking by 
"association", "packet transmssion/reception", etc.), the whole of it is gone 
through when running the tests.
If you are interested in seeing/learning how that's implemented I am afraid you 
need to look into the code tho.

With regards to performance: no, there're no reports. However, something can be 
retrieved by running the test_sctp.py since at the end it prints out how much 
data has been transferred and how long that took.

VPP has an implementation for SCTP. You can look into /src/vnet/sctp folder to 
see what we currently support in terms of RFC.
Any feedback (and contribution) is very much welcome!
