[vpp-dev] getting segfault in execution of vpp 19.01 having nat configuration with trex

Hi, dear VPP I configured nat on vpp 19.01 and wanted to test it using trex. After a while, vpp got SIGSEGV and all packets were dropped. My vpp version was v19.01.1-2~gd0dcf7685. Here is my vpp configuration: https://paste.ubuntu.com/p/czRf8g6Nt6/ This is trex config file: https://paste.ubuntu

Re: [vpp-dev] ip-rewrite bug?

This also pops up while profiling GRE traffic. Just replacing it with clib_memcpy_fast() seems to be more clear and faster in my case: https://gerrit.fd.io/r/c/17968/ AFAICT this should also fix the bug... Ben > -Original Message- > From: vpp-dev@lists.fd.io On Behalf Of Dave Barach >

Re: [vpp-dev] VPP stats

Hi Ole, I tried various combination of stats and statseg in config file but no joy. For example this conf gives error in 18.10. though by manual it seems ok. stats { socket-name /run/vpp/stats.sock } statseg { size 128M } It would be great if you can point to the documentation for 18.10 or a sam

Re: [vpp-dev] VPP stats

Hi Raj, In case this might help, there is a config for statseg for VPP 18.10 in a dockerfile entrypoint here: https://github.com/cisco-ie/vpp-lab/blob/master/hc2vpp/entrypoint.sh#L21 It seems like the following should work because, default config is /run/vpp/stats.sock statseg { default } Yoha

[vpp-dev] NAT handoff node graph question

Hello,  Once handoff node decides to handoff a pkt to another core, which node on the other core picks the pkt up?  I am using 1807, and it seems like nst44-handoff-classify will send the pkt to either nat44-in2out-worker-handoff or nat44-out2in-worker-handoff node.  nat44-in2out-worker-handoff

Re: [vpp-dev] NAT handoff node graph question

Hi Damjan,  Thanks for the reply. I am not very familiar with VPP yet.  Are you suggesting that the pkt will start its journey all the way from dpdk-input on the new core?  Can't we just send the pkt directly to nat44-in2out node on the new core?  In the code, I see that, we are calling vlib_get

[vpp-dev] VPP unite test with multiple worker threads

Hello,  I can see that we can create pg- interface for unit testing various vpp features.  Is it possible to test multiple workers? How can I make sure the packets will be sent to different workers on a pg- interface? -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. V

Re: [vpp-dev] NAT handoff node graph question

I think I found it.  vlib_frame_queue_main_init (sm->in2out_output_node_index, 0); So, it will be passing to the in2out node of the next core.  Thanks Damjan. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. View/Reply Online (#12490): https://lists.fd.io/g/vpp-dev/mess
