The repo I used for the lcp is https://github.com/pimvanpelt/lcpng.git

I used the following dockerfile to build the image:

I used the sample startup.conf from your blog article

plugins {

2022-12-22 Thread Christopher Adigun

Interface is still down which I need for my use-case because that is where
the BGP communication is taking place.

I tried your git repo and built the container image, now both are working
fine.

This means the official release has an issue like you said.

Thanks for your help!

What is not working? Syncing routes or the interface is still down? If you
configure netns in the startup.conf below the plugin section, you should be
to see configured netns in "vppctl show lcp".

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

2022-12-22 Thread Christopher Adigun

Can you share the git commit id that you used for your 22.10 because I have
tried  *configuration in startup.conf "linux-cp { default netns dataplane
}"* but it is still not working.

I have also tried *22.06* and *23.02-rc0~127*, it's the same issue.

Also which version of vpp was the *linux_nl_plugin.so* added? Trying to see
if I can build the image manually and test.

 One other thing, I am running this in a kubernetes POD, maybe this
 might be affecting something.

 Also can you clarify how to perform *plugin "linux_nl_plugin.so"
 ignore "lcp default netns" configuration?* Should this be placed in
 the startup.conf or init.conf?
 I want to test without netns, I tried the following in the startup
 config but vpp was crashing

 plugin "linux_nl_plugin.so" {
   ignore "lcp default netns"
 }

 I also tried using the full command in init.conf but that did not work.

Hi Matt

I can confirm for VPP 22.10
- command "vppctl lcp default netns dataplane" enable synchronizing
interfaces, synchronizing routes fail
- configuration in startup.conf "linux-cp { default netns dataplane }"
works fine for interfaces and routing

 Hi,

 there can be a few misconfigurations:
 1. "lcp default netns dataplane" start synchronizing
 interfaces/address/etc inside netns "dataplane" (netns "dataplane" must
 exist) - NOT synchronizing routes
 2. plugin "linux_nl_plugin.so" ignore "lcp default netns" configuration
 =>  "linux_nl_plugin.so" will synchronize VPP with default namespace "0"

 Solution with netns:
 0. Create netns "dataplane" with systemd
 1. run VPP inside netns "dataplane" (edit systemd, start after previous
 point)
 2. run Bird inside netns "dataplane" (edit systemd, start after
 previous point)
 3. do not use "lcp default netns dataplane", it is controlled by VPP
 netns

 For running without netns only skip "lcp default netns dataplane".

I run VPP in default netns and Bird2 & iproute2 in the dataplane netns. I
set default netns dataplane in startup.conf also.

I think OP has a different problem, because I do see their netlink messages
arriving otherwise. One test that you can do, is in the network namespace,
change the link attribute (like ip link set  mtu 1500; or ip link set
 up; or down; and then see if 'vppctl show int' reflects that change.
That would demonstrate that end-to-end, netlink messages are arriving from
the dataplane netns, through kernel, through linux_nl plugin and finally
into the dataplane.

One plausible explanation for the behavior is that linux_nl starts the
netlink listener immediately, based on startup.conf, and it does not change
its mind when you specify 'lcp netns default' on the CLI, in other words:
it will only listen to one namespace, namely the one it found when it
started up. I think this is OP's issue, and if so, then 'lcp netns' is
broken in linux-cp, it can never work, and actually should be considered
harmful because there will only be one netns listened to, so changing it
midflight will give erratic results. The same is true for the 'netns'
argument to lcp create -- the only place where linux_nl will ever pick up
netlink messages is in the very first namespace it started in, as specified
in startup.conf.

As a point of comparison - lcpng will start a netlink listener *once the
first LIP is created*; which is why it will start the listener in either
what was setup in startup.conf, or what it changed to with 'lcp default
netns', to any value set before the very first interface pair is created.
'lcp default netns' works there, but as with linux_nl, if any LIP is
created in a netns other than the initial one which has the (one and only)
netlink listener in it), it will give unexpected results.

I think we should:
- remove lcp netns default from CLI
- remove changing the netns from API
- force use of only startup.conf to start the netlink listener in that, and
only that, network namespace.

Thoughts ?

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

2022-12-22 Thread Petr Boltík

I'm so sorry ... this is a new issue. I don't know why the lcp tap
interface goes down.

Can you start it manually?
1. remove command:
lcp default netns 'dataplane' (do not use it when VPP already runs in a
specific namespace)
lcp lcp-sync on
lcp lcp-auto-subint on
2. add ip address inside VPP
vppctl set interface ip address n6 10.0.5.10/24
vppctl set interface state n6 up
vppctl lcp create n6 host-if n6
3. configure linux
ip netns exec dataplane ip addr add 10.0.5.10/24 dev n6
ip netns exec dataplane ip link set dev n6 up

If it does not work, I have no idea. I have never met this issue.

I run VPP in the default netns and use FRR & iproute2 in the dataplane
netns and it works fine. I test this regularly on AWS, Azure, KVM, and bare
metal. I don't set the netns with vppctl CLI commands though, I set it in
startup.conf with 'linux-cp { default netns dataplane }'. I will look into
whether something is broken with the CLI command.

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

2022-12-22 Thread Christopher Adigun

Now when I start both bird and vpp in the dataplane netns, the dpdk
interface goes into down state in the dataplane nents:

In VPP, all the interfaces are up:

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

2022-12-22 Thread Petr Boltík

Hi,

- there is no " ignore lcp default netns" declaration in startup.conf or
init.conf. If you start VPP(systemctl vpp start) with no netns configured,
plugin linux_nl_plugin.so will not sync correct routing table and fail.
- If you run the entire VPP process inside netns dataplane, you can skip
configuration line "lcp default netns dataplane".
- To make "plugin linux_nl_plugin.so" working, you need to run VPP inside
netns dataplane (same as bird). This can be done by editing VPP systemd
startup file (add something like "
NetworkNamespacePath=/var/run/netns/dataplane" ) and ensuring that netns
"dataplane" will be started first.

Petr.

Hi Petr,

Thanks for the response, bird is actually running in the dataplane ns:

One other thing, I am running this in a kubernetes POD, maybe this might be
affecting something.

Also can you clarify how to perform *plugin "linux_nl_plugin.so" ignore
"lcp default netns" configuration?* Should this be placed in the
startup.conf or init.conf?
I want to test without netns, I tried the following in the startup config
but vpp was crashing

plugin "linux_nl_plugin.so" {
  ignore "lcp default netns"
}

I also tried using the full command in init.conf but that did not work.

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

2022-12-22 Thread Petr Boltík

Hi,

there can be a few misconfigurations:
1. "lcp default netns dataplane" start synchronizing interfaces/address/etc
inside netns "dataplane" (netns "dataplane" must exist) - NOT synchronizing
routes
2. plugin "linux_nl_plugin.so" ignore "lcp default netns" configuration =>
"linux_nl_plugin.so" will synchronize VPP with default namespace "0"

Solution with netns:
0. Create netns "dataplane" with systemd
1. run VPP inside netns "dataplane" (edit systemd, start after previous
point)
2. run Bird inside netns "dataplane" (edit systemd, start after previous
point)
3. do not use "lcp default netns dataplane", it is controlled by VPP netns

For running without netns only skip "lcp default netns dataplane".

Hoi,

Is bird running in the 'dataplane' network namespace ?

You can register for events, see src/vnet/ip-neighbor/ip_neighbor.api 
want_ip_neighbor_events_v2 for example.
