Hi Andreas/Dave,
I did some experiments to debug the crash.
Firstly, I added some profiling code in vlib/main.c. The code basically is
added to know the timer_wheel slips that can cause such havocs(as mentioned
by Andreas). There are slippages as you can see from the data collected
from the core
Dear All,
I have two questions on how to configure an VXLAN ACL on vpp:
1. how to match a special VXLAN session, include the soure IP, the soure UDP
port and the VNI field.
2. how to match the inner ethernet header and the inner IP header.
does anyone can share some configuretion or idea?
Dear VPP Folks,
I found vpp assertion failed when nat44 forward is enabled. I'm using vpp
version on master branch.
I configured a simple nat scenario with nat44.
My startup.conf :
unix {
interactive
nodaemon
cli-listen /run/vpp/cli.sock
cli-no-pager
poll-sleep-usec 100
}
api-trace {
on
}

Hi all,
Just a friendly reminder that tomorrow 18:00 UTC is our milestone RC1, at which
point we are making a new LTS branch stable/2009 off master and building the
RC1 artifacts.
Committers - please avoid merging risky commits to master until my email that
RC1 milestone is completed.
--a /*
Ok. I think, required changes would be more complex / involved than I initially
imagined.
Can you please make these changes.

Thanks & Regards,
Murthy

That’s a very good point. Looking at vnet_buffer, there seems to be some space
left in it for this case …

Thanks Klement for the quick response.
I can make the changes you suggested. But, one major doubt I have is on the
HANDOFF scenario.
Let's say, as part of custom-reasm-node, if the packet is decided to be handed
off to another thread, then the next_node is ALWAYS getting set as
"ip4-full-reass
We are aware of latency issues on jenkins.fd.io. Jenkins requires a
restart to resolve this issue.
Thank you,
Vanessa

Hi Satya,
so this is obviously unfinished. Would you mind writing the code for that? You
just need to steal a piece of code from ip4_sv_reass.c to do that ;-) and then
steer your packets at custom node.

Hi Satya,
it’s also necessary to enable full reassembly feature along with your feature
by calling ip4_full_reass_enable_disable_with_refcnt().
You can take a look at NAT code which already does that -
snat_interface_add_del().
Regards,
Klement
