Re: [vpp-dev] vcl_test_client is failing with Unsupported application config (-108) #vppcom

Hi Sastry, That is pretty weird. Re-check your extended config to make sure it doesn’t have any errors in it. VCL is part of our CI so most probably the issue is some misconfiguration. For older releases you do need to explicitly ask that the event queues be allocated in a memfd segment,

Re: [vpp-dev] vcl_test_client is failing with Unsupported application config (-108) #vppcom

Hi Florin, Once I have session info as below, I am not seeing vpp crash. session { evt_qs_memfd_seg } I am good now and not seeing unsupported application config message also. If I have any other param or empty params, vpp crashes. I think, we need to address this in later vpp versions. COuld

Hi Florin, Both of these are not hit. So, is it config object crash? With Regards Sastry -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. View/Reply Online (#19348): https://lists.fd.io/g/vpp-dev/message/19348 Mute This Topic: https://lists.fd.io/mt/82575076/21656

Try running vpp from gdb or, as previously recommended, try upgrading to latest version. Regards, Florin > On May 5, 2021, at 8:41 AM, Sastry Sista wrote: > > Hi Florin, > I am not seeing even backtrace. bt is just empty now. > Also I have just added session { } with

Hi Florin, I am not seeing even backtrace. bt is just empty now. Also I have just added session { } with empty params and seeing same exit. No clues at vpp. is there any params that I need to add along with session so that it does not exit? With Regards Sastry -=-=-=-=-=-=-=-=-=-=-=- Links:

Re: [vpp-dev] vcl_test_client is failing with Unsupported application config (-108) #vppcom

Hi Sastry, Can’t do much without a backtrace. Also, not entirely sure how vcl got a reply if vpp crashed. Session layer is the main component of the host stack that keeps track of external apps and facilitates the exchange of data and notifications between apps (like vcl) and transports. So

Re: [vpp-dev] vcl_test_client is failing with Unsupported application config (-108) #vppcom

Hi Florin, I tried to add session layer at vpp as below: session { session-baseva 0x20 evt_qs_memfd_seg event-queue-length 10 } vpp is still crashing and not able to run vpp. Also, is session layer important for VCL application to run? I am still seeing

Re: [vpp-dev] vcl_test_client is failing with Unsupported application config (-108) #vppcom

Hi Sastry, As a first step, since you’ve just started development, I’d switch to vpp latest to get recent features and fixes. Regarding the issue you’re hitting, in older releases you had to explicitly request memfd type of segment for the event queues (evt_qs_memfd_seg). Recently that has

Re: [vpp-dev] vcl_test_client is failing with Unsupported application config (-108) #vppcom

Hi Florin, Thank you for the reply. I am trying to develop similar kind of envoy app using VCL. So, I need both socket option for binary API and shared client for rx/tx for TCP data. So, I need use-mq-eventfd at vcl.conf right?. ANyway I tried removing it but still same

Re: [vpp-dev] vcl_test_client is failing with Unsupported application config (-108) #vppcom

Hi, Is there anything configured on vpp side for session layer? Is this vpp 21.06rc0 or something older? The error number seems to suggest an older release. One option would be to just comment out use-mq-eventfd and see if that fixes the issue. Message queue eventfds should work with the
