it always the same frame element which takes a lightning hit?

You could use the vlib_node_runtime_perf_counter callback hook to run code
between node dispatches, which SHOULD give adequate precision.
Alternatively, spin up 1-N threads to run the shaper and driver TX path, and

It'd sure be nice to hear from Neale before we code something like that.

The code manages to access a poisoned adjacency – 0x131313 fill pattern –
copying Neale for an opinion.

Hello All,
Unless you fully communicate your configuration, you’ll have to debug the issue
yourself. Are you using the standard handoff mechanism, or a mechanism of your
own design?
The handoff demo plugin seems to work fine... See
../src/examples/handoffdemo/{README.md, node.c} etc.
DBGvpp# sh trace
API messages in network byte order made sense 10 years ago when I worked with a
mixed x86_64 / ppc32 system. As Damjan points out, API interoperability between
big-endian and little-endian systems is a boutique use-case these days.
Timing is key. We won’t be able to cherry-pick API message
That patch looks OK, but it never – not even once – passed validation. I
rebased it without difficulty, but unless it passes validation it’s not going
to be merged.
It would have been a Good Thing to have pursued the matter at the time, rather
than a long time after the fact.

Dear Andreas,
Do you have a handy list of places which convert netmasks to lengths?
Regardless of what one might do with min_log2, we ought to clean up those
places in time for the 20.05 release (if possible).

Hi,

Right, sorry, I've pinged the Responsible Parties offline to fix the problem.
vec_len(vlib_mains) will be 1 in an init routine. Start_threads() which builds
the final vlib_mains vector doesn't occur until just prior to main dispatch

vec_elt_at_index (...) is meant to catch this
Thanks for the patch, merged...
The cpu tick counters are different on each thread, so calling vlib_time_now
(wrong_vlib_main_t *) wrecks the victim thread's timebase. Knock-on effects
include all manner of obscure / hard-to-reproduce failures.

Hi Dave and Damjan,
Here is instruction and register info:

Could we please see the faulting instruction, as well as the vector register
contents involved?
As in "x/i $pc", and the ymmX registers involved?
If the vector instruction requires alignment, "movaps" or similar, it wouldn't
be a shock to discover an unaligned address. We've already found and
If you want to count things in data plane nodes, use a per-node counter and the

To count every packet fed to the node dispatch function, you can bump a node

Also:

For now, we support 19.08 (LTS), and 20.01.
20.05 will be released next month.
We do not support 19.01.

+1, with two additional notes.
18.01 is over two years old. It's not supported anymore. If you absolutely must
go there, "Use the Force and Read the Source..."
Since vpp 18.01 was released, I've rewritten the pcap trace cli. Ben is
probably right, but that's about all I can say at this point.
Ack. If all else fails, suggest a quick peek at the assembly code.
