[vpp-dev] #vpp-hoststack - Issue with UDP receiver application using VCL library

Hi , I am trying some host application tests ( using LD_PRELOAD) .  TCP rx and tx both work fine. UDP tx also works fine. The issue is only with UDP rx .  In some discussion it was mentioned that session layer does not support connection-less transports so protocols like udp still need to

> This should be done as an intermediate agent. I have a hypothetical question. (I am not trying to be cheeky. I feel there may be a difference, I just do not see it.) Imagine a world where VPP supports (CLI via vppctl and) binary API only over shared memory. No support for binary API over Unix

Re: [vpp-dev] #vpp-hoststack - Issue with UDP receiver application using VCL library

Hi Raj, Session layer does support connection-less transports but udp does not raise accept notifications to vcl. UDPC might, but we haven’t tested udpc with vcl in a long time so it might not work properly. What was the problem you were hitting in the non-connected case? Regards, Florin >

Re: [vpp-dev] #vpp-hoststack - Issue with UDP receiver application using VCL library

Hi Florin, Thanks! for the reply. I realized the issue with the non-connected case. For receiving datagrams, I was using recvfrom() with DONOT_WAIT flag because of that vppcom_session_recvfrom() api was failing. It expects either 0 or MSG_PEEK flag. if (flags == 0) rv =

Re: [vpp-dev] Arm verify job broken

short answer: fixed.. longer answer: a ci-management patch which did a whole bunch of cleanup and readability improvements accidentally separated two scripts that had to stay together. Having the script apart meant arm was using only 1 core instead of the correct number of 16 cores. This

Re: [vpp-dev] vpp crashes on deleting route 0.0.0.0/0 via interface #vpp

Hi, Thanks for the bug report, I’ll fix the crash. A question for you. DBGvpp# ip route add 0.0.0.0/0 table 10 via gre0 Says “all destinations in table 10 are reachable via an interface in table 0”. It implies therefore that all addresses in table 10 refer to the same device in table 0,

vlib_buffer_t has no ethernet_header_t, *vnet_gso_header_offset_parser* ** will failed. I think if vlib_buffer_t valid l2 header, vnet_gso_header_offset_parser should skip *ethernet_header_t* parse. Below is the VPP crash message: > > 0: /home/dev/code/net-base/build/vpp/src/vnet/ip/ip.h:205 >

Re: [vpp-dev] #vpp-hoststack - Issue with UDP receiver application using VCL library

Hi Raj, First of all, with this [1], the vcl test app/client can establish a udpc connection. Note that udp will most probably lose packets, so large exchanges with those apps may not work. As for the second issue, does [2] solve it? Regards, Florin [1]
