Re: [vpp-dev] get the same IP address from DHCP server for two VPP DHCP clients

[Burt Silverman]

Yes, not only do they have the same transaction id, they have the same
Client ID. Option: (61):  3d 08 76 70 65 20 31 2e  30
00 =.vpe 1. 0.

Different clients need to have unique Client IDs.

Re: [vpp-dev] get the same IP address from DHCP server for two VPP DHCP clients

[pvinci]

dhcp tests seem to be failing frequently, but inconsistently, passing on 
subsequent retries.  

An example can be seen in

Re: [vpp-dev] get the same IP address from DHCP server for two VPP DHCP clients

[Xuekun]

No, they have different MACs.

Here is the JIRA (https://jira.fd.io/browse/VPP-1528) with pcap captured. My 
quick glance found the two SUTs sent the same “transaction id” in the DHCP 
discover that why they got the same IP address.

1,SUT1_TX:

[cid:image001.jpg@01D4913F.67EE3AA0]

2, SUT2_TX:

[cid:image002.jpg@01D4913F.67EE3AA0]

Is there anyone can take a look? 😊
Thanks.

This sounds more like dhcp server misconfiguration than a dhcp client bug in 
vpp, but anyway...

You can submit a Jira ticket, but it will end up in “information request” state 
immediately if it doesn’t include a pcap capture which shows both transactions. 
The vpp dhcp client code is not new, and it’s been tested pretty carefully.

Re: [vpp-dev] Build fails on CentOS with VMBus.

[Damjan Marion via Lists.Fd.Io]

Stephen,

Can you make this dependency optional? CMake detect presence of libuuid and then
conditionally compile vmbus code?

In some cases that library might not be present, specially in some embedded 
cases...

That will also allow us to merge that code immediately and later we can fix 
different distros.

[vpp-dev] VPP 19.01 Release Plan

[Andrew Yourtchenko]

Dear All,

During the November 27 VPP meeting we discussed the 19.01 release.

The release plan and its agreed schedule are at the following location:
https://wiki.fd.io/view/Projects/vpp/Release_Plans/Release_Plan_19.01

Please add the features that you are planning to release in 19.01 by
either editing the wiki page
 (I have added a couple of template lines for your copy-paste
convenience), or by sending them directly to me.

Thanks a lot!

[vpp-dev] Request to Reviewing of Getting max connection table entries in vpp ACL

Dear vpp,

I'd just written an api with vpp_api_test  in vpp ACL plugin in order to
get max connection  table entries. Here it is the link of gerrit:

https://gerrit.fd.io/r/#/c/16411/

I think it can be useful.
I appreciate if somebody  reviews it.

Hi John,

There is bug in NAT code for ICMP fragments. I will fix it as soon as possible.

Hi Ole,

I've added a relevant packet trace. Is that adequate?

Thanks,

I did, however this is not an option as I'd like to keep my "entire topology 
running on the same machine" philosophy.

Also, I think this could be a plus for the router plugin to handle 
multi-instance/memif setups. Though, I don't see how we could do.

Cheers,
Justin

[vpp-dev] CSIT IPv6 IPSec transport mode tests are failing

[Jan Gelety via Lists.Fd.Io]

Hello vpp-dev,

After merge of patch https://gerrit.fd.io/r/#/c/16350/5/src/vnet/ipsec/ we see 
all IPv6 IPSec transport mode tests are failing. The reason seem to be the 
change in esp_encrypt.c file where only size of ip4 header is taken in the 
account.

Following have been testsed with vpp build 19.01-rc0~441-g521a8d7~b5917_amd64.

In the test we first compose (with scapy) outgoing encrypted packet of len 106B:

Sending packet out of ens6 of len 106
###[ Ethernet ]###
  dst   = fa:16:3e:d7:aa:83
  src   = fa:16:3e:83:b3:22
  type  = 0x86dd
###[ IPv6 ]###
 version   = 6L
 tc= 0L
 fl= 0L
 plen  = 52
 nh= ESP Header
 hlim  = 64
 src   = 3ffe:5f::1
 dst   = 3ffe:5f::2
###[ ESP ]###
spi   = 0x3e8
seq   = 1
data  = 
'\xff\x0fF\xbb\xfa\xbb\xff}\xac\xa12\xb0\xd3\x9d\xf2\xe2G\x181_\xbd\xf3\xd5\xb4\xd4\xcc\xcf\xfc\xfd\x18\x8cb\x1b\xc8\x8b\xc9\x8e\xccFQ+e\x8a\xd1'

but len of received packet (from VPP) is 122:

Received packet on ens6 of len 122
###[ Ethernet ]###
  dst   = fa:16:3e:83:b3:22
  src   = fa:16:3e:d7:aa:83
  type  = 0x86dd
###[ IPv6 ]###
 version   = 6L
 tc= 0L
 fl= 0L
 plen  = 68
 nh= ESP Header
 hlim  = 254
 src   = 3ffe:5f::2
 dst   = 3ffe:5f::1
###[ ESP ]###
spi   = 0x3e9
seq   = 1
data  = 
"&\xae\xe9\xab'\x04\x1a\xe2\xd7x\x8bR\x96\x0cJ\xf1\xf7\r\r\xad\xac\xd6\xa2e(\x06\xdf\x85G\xedk\xa1\x15e\xe2\xc4\r\xdcw\\#\xb1\xa8\xf7\xbcK\t_\x1b\x82%\x11\xf8h\xe1\xefG\xbdNB"


Could you, please, fix it?

Thanks,
Jan

Deterministic mode doesn’t support fragments.

​Hi Matus!



I've picked this up again for testing and verifying. I am running it in 
deterministic mode now, and it's still displaying the same issue.



Do you by any chance have the commit at hand? Is the fix only applied to 
dynamic NAT and not deterministic?

Re : [vpp-dev] Maintainer router plugin

Hello Justin,
Regarding multi instance, have you considered running multiple instances of VPP 
in different containers?

Of course, if I find some free time. Anyone interested in working on this ?

How do you determine which namespace(s) to look at ? Or do you take care of 
all namespaces by default ?

Also, would multi-instance mode be feasible ?

Cheers,
Justin

Objet : [vpp-dev] Problem with adding second IP to interface

Hi Dear VPP

I configured a topology using two clients and one DUT (VPP).
Topology: https://paste.ubuntu.com/p/gNy3ZZyTfD/

In my scenario Client1 ping Clinet2 and Client2 ping Client1. While it is 
operational, I add second IP (0.2.0.3/8) to GigabitEthernet3/0/0. I see both 
pings are dropped for a while (about 30 secs).
My question is why this happen? I expected that pings were working continuously 
during second IP adding.

Thanks,
Sincerely
