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

[alp . arslan]

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.

Hi Alp Arslan,

Please see below slides for more details. There is some packet trace for
your reference.

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.

Dear All, 

I am trying to evaluate the support of pppoe in vpp. However, I am facing
some issues, here is my startup conf file. 

unix {
  nodaemon
  log /var/log/vpp/vpp.log
  full-coredump
  cli-listen /run/vpp/cli.sock
  gid vpp
}
api-trace {
  on
}
api-segment {

socksvr {

cpu {

corelist-workers 2,4,3,5
}
dpdk {

uio-driver vfio-pci
socket-mem 2048,2048
}
plugins {
plugin default { enable}
}
tuntap {
  enable
  ethernet
  name newtap
}

After that I run the following commands: 

vpp# set interface state TenGigabitEthernet5/0/1 up vpp# set interface state
local0 up

Now at this point if I try to connect from the pppoe client, I can see three
PADI request reaching VPP, and VPP trying to forward them at local0
interface. 
To forward this traffic to the tap port instead, I use this command. 

vpp# create pppoe cp cp-if-index 2

The help and the documentation for this command show this "create pppoe cp
if-name  [del]", which doesn't work.
Now at this moment, I was expecting the VPP to forward the PADI request to
tuntap-0 interface, but I don't see anything in the VPP counters, nor by
using tcpdump on interface

[vpp-dev] Regarding VLIB_REGISTER_NODE

[Prashant Upadhyaya]

Hi,

I have a registered node like the following --

VLIB_REGISTER_NODE (MyNode) = {
.name = "MyNode",
.
.
.n_next_nodes =N,
.next_nodes = {
[firstone] = "error-drop",
[secondone] = "ip4-lookup",
[thirdone] = "ip6-lookup",
[fourthone] = "may-or-may-not-be-loaded-node",
.
.

Now I want to be able to run the system whether the fourth one above
is loaded or not as a .so
The business logic in my code takes care that I never use the fourth
one in case it is not loaded. I have a private configuration which
tells me whether the fourth one is present in deployment or not.

But the VLIB_REGISTER_NODE requires the wiring at compile time like the above.
And the system will not startup if the fourth one is not actually
present in deployment

So I want to avoid mentioning the fourth one in the VLIB_REGISTER_NODE
of MyNode as one of the next_nodes.
And then how to add it as one of the next_nodes from runtime for
MyNode when my private configuration tells me that the fourthone
indeed is existing in the deployment ? I am looking for some API to
wink in the fourth one at runtime into .next_nodes of MyNode.

Regards
-Prashant

Re: [vpp-dev] Regarding VLIB_REGISTER_NODE

[Dave Barach via Lists.Fd.Io]

Use vlib_node_add_next(...) to create the graph arc at your convenience. 
Memorize the arc index when you create it, so you can set e.g. next0 to the 
correct value in MyNode.

Do you mean it is impossible to have packet processing and memory operation at 
the same time,
for example doing vec_validate or vec_free when NAT plugin is working and 
create new session.

I have drop rate when vec_free or vec_vlidate for memory size greater than 3GB. 

What are your suggestions for such problems?

Re: [vpp-dev] Memory Performance issue #vpp

[Dave Barach via Lists.Fd.Io]

There is no such thing as a free lunch.

If you force a fresh allocation measured in gigabytes, the memory allocator 
will mmap(...) a bunch of (4k) pages which will incur (expensive) pagefaults as 
they’re populated. Vec_validate(...) copies data when necessary. When 
structures grow to gigabytes, that takes a measurable amount of time and will 
almost certainly result in packet drops.

Preallocation is the only strategy for avoiding packet drops when data 
structures expand beyond a certain size. Either that, or simply accept 
vector-size excursions until vpp reaches steady state: at that point, data 
structures shouldn’t have to expand, and you shouldn’t drop any more packets.

Note that vec_reset_length(v) is highly preferable to constant cycling of fresh 
large vectors from vec_validate(...) / vec_add1(...) to vec_free(...).

HTH... D.

Jan,

vpp-ext-deps is not official vpp package, it is just helper package for 
developers.
It is not needed or intended to be used by end users

Why do you need it?

Re: [vpp-dev] Memory Performance issue #vpp

[david . leitch . vpp]

Do you mean it is impossible to have packet processing and memory operation at 
the same time,
for example doing vec_validate or vec_free when NAT plugging is working and 
create new session.

I have drop rate when vec_free or vec_vlidate for memory size greater than 3GB. 

What are your suggestions for such problems?

FYI just to be on same page things are not broken in 1810 so I don’t think its 
needed. Its only broken in current master.

Is this something which should go also on stable/1810 for a potential future

If so could you please cherry pick it to that branch?

I toned down the dpdk resource allocation to default:

  no-multi-seg
  log-level debug

But here is the problem (for 16G of Hugepage memory):
With:
2MB (nr_hugepages: 8192)
GRUB_CMDLINE_LINUX="default_hugepagesz=2M hugepagesz=1G hugepages=16 
hugepagesz=2M hugepages=8192 iommu.passthrough=1 isolcpus=16-45 nohz_full=16-45

vs 1GB (nr_hugepages: 16)
GRUB_CMDLINE_LINUX="default_hugepagesz=1G hugepagesz=1G hugepages=16 
hugepagesz=2M hugepages=8192 iommu.passthrough=1 isolcpus=16-45 nohz_full=16-45 
rcu_nocbs=16-45"

I am getting a performance improvement of 49% when I use 1G hugepages compared 
to 2MB.
I am not an expert on hugepages to pinpoint the exact reason but it will surely 
help if you can fix the 1G hugepage issue.

Thank you

OMG, you are good in wasting memory. 1G pages, 2G per socket given to dpdk to 
hang empty :)
128K buffers

For a start can you switch default page size to 2M. newer x86 kernels ignore it 
but maybe it behaves
differently on aarch64...

In the meantime I will fix few coverity issues...

Re: [vpp-dev] [tsc] [csit-dev] VPP 18.10 is out!!!

[Jan Gelety via Lists.Fd.Io]

Hello Damjan,

Thanks for the info.

In the past there was used igb_uio driver for CSIT tests and former 
vpp-dpdk-dkms deb package, replaced by vpp-ext-deps package now, was used as 
source of this driver for tests on ubuntu.

But CSIT tests were modified to use vfio-pci driver so we were able to remove 
CSIT dependency on vpp-ext-deps package in master [0] as well as rls1810 [1] 
branches.

Thus we don’t need it anymore.

Thanks,
Jan

Re: [vpp-dev] clearing stats

Ole,

thanks!

on a related note: do you intend that people will add to the
stat_directory_type_t with more complex specific types or keep it to
more primitive generic types?

Re: [vpp-dev] Problem switching a bonded interface from L2 to L3 mode

Are you using VPP native bonding driver or DPDK bonding driver? How do you 
configure the bonding interface? Please include the configuration and process 
to recreate the problem.

I am very grateful for your help.

And when I test the VLAN, maybe I find a bug that if I switch the mode of the 
Bonding interface to L2 and then switch back to L3，the bonding interface can 
not work as before.

I have found the error code that is in the mode switch function of bonding 
device: when set the mode of bonding interface to l2, all the members of the 
bonding interface will be set to l2, but when set the bonding interface back, 
all the members do not recover to l3.



At last I have another doubt that when I configure an IP address for an 
interface, then I ping the address from VPP, it’s failed, why?should I do other 
more settings?

I have tested it，But there is something wrong. when I receive an arp or ICMP

The equivalent of VLAN on a switch in VPP is a bridge domain or BD for short.  
One can put interfaces or VLAN sub-interfaces in a BD to form a L2 network 
among all interfaces in it.  One can also create a loopback interface, put it 
in a BD as its BVI (Bridge Virtual Interface) and assign IP addresses to it.  
Then packet can be IP forwarded into a BD through its BVI.



Following is the VPP CLI sequence to create a loopback (resulting in interface 
name loop0), put it in BD 13 as a BVI, and put an IP address on it:



loopback create mac 1a:2b:3c:4d:5e:6f

set interface l2 bridge loop0 13 bvi

set interface state loop0 up

set interface ip address loop0 6.0.0.250/16

I have a question:

Does vpp has the function like the configuration example:

interface f0/1

switchport access vlan 10



Interface vlan 10

ip address 10.0.0.1 255.255.255.0



If vpp has the function, where can I find the command and the source code?



Another question, does vpp support superVLAN?



anyone who knows please tell me, appreciate for your reply very much!

in a BD as its BVI (Bridge Virtual Interface) and assign IP addresses to it.  
Then packet can be IP forwarded into a BD through its BVI.



Following is the VPP CLI sequence to create a loopback (resulting in interface 
name loop0), put it in BD 13 as a BVI, and put an IP address on it:



loopback create mac 1a:2b:3c:4d:5e:6f

set interface l2 bridge loop0 13 bvi

set interface state loop0 up

set interface ip address loop0 6.0.0.250/16

John

I have a question:

Does vpp has the function like the configuration example:

interface f0/1

switchport access vlan 10



Interface vlan 10

ip address 10.0.0.1 255.255.255.0



If vpp has the function, where can I find the command and the source code?



Another question, does vpp support superVLAN?



anyone who knows please tell me, appreciate for your reply very much!

Re: [vpp-dev] [tsc] Project Proposal for Sweetcomb

[Ni, Hongjun]

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.

Thanks a lot,

Thank you for the proposal :)  Per the FD.io technical charter, all proposals 
must be out for public review for two weeks prior to approval by the TSC.  I 
believe this makes Nov 8 the earliest TSC meeting where we could approve at the 
TSC.  Would you like to schedule the project creation review for the Nov 8 8am

Yeah, i already fixed that but it is not merged yet. This is just prealloc

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!

[vpp-dev] Memory Performance issue #vpp

[david . leitch . vpp]

Hi,
 
I tested VPP performance for CGNAT in Deterministic mode; While VPP is working 
and has sessions, "show memory" command causes huge drop rates or when I want 
to add another deterministic mapping it takes long delay (for memory 
allocation) and again huge drop rate occurs that relate to memory allocation.
 
First, I thought drop rate was for main heap memory locking, so I changed 
source code and comment mheap_maybe_lock and mheap_maybe_unlock on mheap_usage 
command, but when the main heap is busy I have drop rate for incoming traffic. 
:(
 
Is it normal behavior Or it is performance problem for memory?
 
Thanks!

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

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.

Alp Arslan

I suggest you leverage tapv2, and also need some rework for PPPoE plugin.

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

Dear All, 

I am trying to evaluate the support of pppoe in vpp. However, I am facing some 
issues, here is my startup conf file. 

unix {
  nodaemon
  log /var/log/vpp/vpp.log
  full-coredump
  cli-listen /run/vpp/cli.sock
  gid vpp
}
api-trace {
  on
}
api-segment {
  gid vpp
}
socksvr {
  default
}
cpu {
main-core 1
corelist-workers 2,4,3,5
}
dpdk {
dev :05:00.1
uio-driver vfio-pci
socket-mem 2048,2048
}
plugins {
plugin default { enable}
}
tuntap {
  enable
  ethernet
  name newtap
}

After that I run the following commands: 

vpp# set interface state TenGigabitEthernet5/0/1 up vpp# set interface state
local0 up

Now at this point if I try to connect from the pppoe client, I can see three 
PADI request reaching VPP, and VPP trying to forward them at local0 interface. 
To forward this traffic to the tap port instead, I use this command. 

vpp# create pppoe cp cp-if-index 2

The help and the documentation for this command show this "create pppoe cp 
if-name  [del]", which doesn't work.
Now at this moment, I was expecting the VPP to forward the PADI request to
tuntap-0 interface, but I don't see anything in the VPP counters, nor by using 
tcpdump on interface "newtap" which is the kernel facing side of "tuntap-0" 
interface. 

My question is, Is my approach correct? Are the PADI requests forwarded to the 
tuntap-0 interface? If not where do they go? I cannot find any good 
documentation on this anywhere. 
Any help regarding this would be highly appreciated. 

Regards,
Alp Arslan

I see on my setup that these two drivers are loaded : vfio and

Can anyone tell if this could be causing some issue? Would the issue go
away if I remove these?

Re: [vpp-dev] Memory Performance issue #vpp

[Matus Fabian -X (matfabia - PANTHEON TECHNOLOGIES@Cisco) via Lists.Fd.Io]

Hi,

Deterministic NAT preallocate vector with 1000 session slots for each host from 
inside network range, so it will take some time

Subject: [vpp-dev] Memory Performance issue #vpp

Hi,

I tested VPP performance for CGNAT in Deterministic mode; While VPP is working 
and has sessions, "show memory" command causes huge drop rates or when I want 
to add another deterministic mapping it takes long delay (for memory 
allocation) and again huge drop rate occurs that relate to memory allocation.

First, I thought drop rate was for main heap memory locking, so I changed 
source code and comment mheap_maybe_lock and mheap_maybe_unlock on mheap_usage 
command, but when the main heap is busy I have drop rate for incoming traffic. 
:(

Is it normal behavior Or it is performance problem for memory?

Thanks!

Re: [vpp-dev] Memory Performance issue #vpp

[david . leitch . vpp]

hi Matus

I know it will take some time when add new deterministic mapping.
But why "show memory" command has drop rate 
Or why adding new deterministic mapping cause drop rate

Thanks !

Why do you need that package, it is not end user package, it is just helper

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

[alp . arslan]

Dell - Internal Use - Confidential  

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

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.

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

Dear All, 

I am trying to evaluate the support of pppoe in vpp. However, I am facing
some issues, here is my startup conf file. 

unix {
  nodaemon
  log /var/log/vpp/vpp.log
  full-coredump
  cli-listen /run/vpp/cli.sock
  gid vpp
}
api-trace {
  on
}
api-segment {
  gid vpp
}
socksvr {
  default
}
cpu {
main-core 1
corelist-workers 2,4,3,5
}
dpdk {
dev :05:00.1
uio-driver vfio-pci
socket-mem 2048,2048
}
plugins {
plugin default { enable}
}
tuntap {
  enable
  ethernet
  name newtap
}

After that I run the following commands: 

vpp# set interface state TenGigabitEthernet5/0/1 up vpp# set interface state
local0 up

Now at this point if I try to connect from the pppoe client, I can see three
PADI request reaching VPP, and VPP trying to forward them at local0
interface. 
To forward this traffic to the tap port instead, I use this command. 

vpp# create pppoe cp cp-if-index 2

The help and the documentation for this command show this "create pppoe cp
if-name  [del]", which doesn't work.
Now at this moment, I was expecting the VPP to forward the PADI request to
tuntap-0 interface, but I don't see anything in the VPP counters, nor by
using tcpdump on interface "newtap" which is the kernel facing side of
"tuntap-0" interface. 

My question is, Is my approach correct? Are the PADI requests forwarded to
the tuntap-0 interface? If not where do they go? I cannot find any good
documentation on this anywhere. 
Any help regarding this would be highly appreciated. 

Regards,
Alp Arslan
