Re: [vpp-dev] cmake is on

[Kingwel Xie]

Hi Damijan,

Thanks for the great job done. It is now much faster.

We noticed a difference between using cmake and automake in the latest code:

Vppinfra/qsort.c is included in vppinfra/CMakefile.txt but not in vppinfra.am, 
which creates a situation that cmake image would be linked to the qsort.c but 
automake linked to glibc.

The reason why we noticed is there is a buffer overrun bug in qsort.c that 
causes cli crashed occasionally.

Please comment how to fix. Personally I'd like to remove qsort.c, like before.

Regards,
Kingwel

Dear all,

We just switched from autotools to cmake and retired all autotools related 
files in src/.

All verify jobs are ok, and we also tried it on 3 different x86 and 2 different 
ARM Aarch64 machines.

Due to blast radius, i will not be surprised that some small issues pop out, 
but i don't expect anything hard to fix.

Let us know if you hit something...

PS As a part of this change, CentOS 7 build are now using devtoolset-7, so they 
are compiled with gcc-7, which also means images have support for Skylake 
Servers (AVX512).

Hi All,

Creation of a sub-interface with ‘untagged’ option fails with the message “ 
create sub-interfaces: vlan is already in use” . Any idea what I am missing 
here ? There is no other configs present and trying to create sub-interface for 
the first time.

vpp# create sub-interfaces GigabitEthernet5/0/0 1 untagged
create sub-interfaces: vlan is already in use


Thanks,

Re: [**EXTERNAL**] Re: [vpp-dev] What is 'punt' in 'set interface' command

[Chandra Mohan, Vijay Mohan]

Thanks for the response. 

I created a sub-interface on a physical interface and am trying to set the 
interface state of that sub-interface as 'punt' . Its failing with a message :

vpp# set interface state TenGigabitEthernet3/0/0.1 punt
set interface state: super-interface TenGigabitEthernet3/0/0 must be down/punt

Question is, the physical interface must be 'down/punt' in order to 
successfully set 'punt' on the corresponding sub-interface whose state would 
eventually become 'down/punt' . Was wondering what's the real purpose of this 
configuration ? If the physical interface is down it wouldn’t receive any 
frames.  

I am missing something here and trying to figure what that is.

Looking to understand more about what this means. I am trying to explore if 
there is a way by which control frames can be forwarded to CPU and was 
wondering if ‘punt’ is that way to do this.

[vpp-dev] vpp-arm-verify-master-ubuntu1604 failing

[Matthew Smith]

Hi,

The jenkins job vpp-arm-verify-master-ubuntu1604 seems to have failed every
time it has run over the last 36 hours or so. Is that a known issue?

https://jenkins.fd.io/job/vpp-arm-verify-master-ubuntu1604/buildTimeTrend

Is vpp-dev the appropriate place to report issues like this? Or is there
some other email alias that will go directly to whomever might need to kick
jenkins?

Thanks,
-Matt

All plugin error counters get there by default.
If you add new named counters, they will also get there without any action 
required from the plugin.

Use vpp_get_stats to list, dump and poll counters as an example of external 
application.
Otherwise there’s also a python interface.

Re: [EXTERNAL] [vpp-dev] Pager Buffer limit

[Chris Luke]

I should add that after the pager limit is exceeded, it simply disables the 
pager (if that does not work and it eats the output, please let me know!)

This is to limit memory consumption more than anything since it has to keep all 
the CLI output in memory to be able to paginate it. 100K lines was thought a 
reasonable default limit for this – at 80 characters per line this would be 
about 8MB+overhead and thus doesn’t put too much pressure on the heap. I would 
recommend you use vppctl and send the output to a file, or pipe to less, if you 
really do generate that much output.

Chris.

I believe there's a missing CPU_TYPE detection in here "src/cmake/cpu.cmake"I
don't have an OCTEONTX machine to check so if you can provide them (or submit a
patch with those) I think that could fix it...

Re: [vpp-dev] crash when pressing TAB on CLI

[Dave Barach via Lists.Fd.Io]

In future, please refer to https://wiki.fd.io/view/VPP/BugReports. The issue 
you're reporting is not trivially reproducible.

At a minimum: we'll need a backtrace from a debug image, the vpp version 
string, the vpp startup config, and the connection method you used.

Subject: [vpp-dev] crash when pressing TAB on CLI

Hi,
I have a problem with the latest code. When I execute 'set interface ip' on the 
command line and press TAB, it will crash. The current direct reason is found 
in the qsort function. When comparing strings, the access is Illegal memory, 
the specific code is as follows:

for (min = base; (hi = min += q->qsz) < max;)
{
  while ((*q->qcmp) (hi -= q->qsz, min) > 0);
  if ((hi += q->qsz) != min)
   {
 for (lo = min + q->qsz; --lo >= min;)
   {
 c = *lo;
 for (i = j = lo; (j -= q->qsz) >= hi; i = j)
  *i = *j;
 *i = c;
   }
   }
}

You are using 1GB hugepages and you have not configured them.
Better use 2MB hugepages if you are running vpp just for learning.

Also share the contents of "/etc/default/grub". Looks like you have 
set 1GB

as default hugepage size.

Actually the output log is the complete opposite!!!That log is simply

that you have _NOT_ reserved 1GB hugepages but rather the 2MB ones.

I suppose you're running on a NUMA machine? Apparently the hugepages 
allocation
has run out on one of the two socket and it's _warning_ you that 
memory will be
taken from the other one. It's warning you because it's a performance 
hit to
access remote-node memory...Again this is a _warning_ not an error. 
Having said
all that, why don't you follow this page (DPDK) on how to reserve 
hugepages for
NUMA 
machines?https://doc.dpdk.org/guides/linux_gsg/sys_reqs.htmlSomething

like:echo 1024 >

/sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages

You have not binded any port to be used by DPDK... again, take a look 
at this

webpagehttps://doc.dpdk.org/guides/tools/devbind.htmlSomething like
dpdk-devbind
--bind=vfio-pci PCI_BAR_ADDRESSwill map your port (identified by
PCI_BAR_ADDRESS) to the vfio-pci driver.

[vpp-dev] Pager Buffer limit

[siddarth rai]

Hi,

I am working on creating a VPP cli which dumps a lot of info.

Is there any limitation to the number of lines we can print in a paged
format using vlib_cli_output ? I am not able to print more than 100K lines.

Beyond that i get the error "-- pager buffer overflowed --" .
Also, how do I modify this limit ?

Thanks & Regards,
Siddarth

[vpp-dev] Using VPP in Openstack VMs

[Pedro A. Aranda]

Dear all,

I’m trying to setup a VM in OpenStack to run VPP based apps. I intend to use 
ubuntu-xenial or ubuntu-bionic.
What ‘extra’ features do I need to activate? How do I tell OpenStack to 
activate them?

Thanks a lot, /PA

Re: [vpp-dev] Issue in adding 10 G NIC to VPP

[Marco Varlese]

Priyanka,

Please, make sure you have "intel_iommu=on" and "iommu=pt" in your boot grub
configuration.

Also, if you're using (as I presume but you didn't confirmed) a NUMA machine,
remove any configuration about hugepages from the boot grub configuration and
follow the instructions I gave you earlier.

Then, reboot your machine and do not use uio_pci_generic but rather vfio-pci
(edit the startup.conf: change the uio_driver used and modprobe vfio-pci instead
of uio_pci_generic).

Also, please, if things still do not work share:
1) VPP version
2) Content of "startup.conf"
3) Output of "cat /proc/cmdline"

Re: [vpp-dev] Move NSH plugin to VPP project as a separate plugin

[Ni, Hongjun]

Hi Srikanth,

We have no plan to support it yet.

If you require this, could you help to develop this feature and upstream to VPP?
Since NSH plugin has been moved to VPP main repo.

Thanks,
Hongjun

As part of our requirement we are trying to use UDP as a transport layer inline

is there any plan / roadmap to support this ?

This will help to make the maintenance easier, attract more users, and also

I will start by porting task, hoping that it will be merged in 18.10 Release.

Like any other kernel drivers "modprobe vfio-pci"

We want vpp with dpdk plugin. I've just installed vpp using apt-get following 
the steps on this link : 
https://wiki.fd.io/view/VPP/Installing_VPP_binaries_from_packages.
Does DPDK have to be spearely installed to be able to use the dpdk plugin?

Thanks a lot,
Arijit.

Arijit,

Few questions:
1) What NIC is your 10G NIC?
2) Your configuration is wrong:
ixgbe is not a uio-driver... you should choose between vfio-pci, 
uio-pci-generic or igb_uio (and make sure to have that driver module loaded in 
the kernel beforehand).
3) I assume you're trying to use VPP with DPDK plugin enabled. Can you confirm?

Actually the output log is the complete opposite!!!That log is simply stating
that you have _NOT_ reserved 1GB hugepages but rather the 2MB ones. See below

I suppose you're running on a NUMA machine? Apparently the hugepages allocation
has run out on one of the two socket and it's _warning_ you that memory will be
taken from the other one. It's warning you because it's a performance hit to
access remote-node memory...Again this is a _warning_ not an error. Having said
all that, why don't you follow this page (DPDK) on how to reserve hugepages for
NUMA machines?https://doc.dpdk.org/guides/linux_gsg/sys_reqs.htmlSomething
like:echo 1024 > 
/sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-

You have not binded any port to be used by DPDK... again, take a look at this
webpagehttps://doc.dpdk.org/guides/tools/devbind.htmlSomething like 
dpdk-devbind 
--bind=vfio-pci PCI_BAR_ADDRESSwill map your port (identified by
PCI_BAR_ADDRESS) to the vfio-pci driver.
