Ikev2ProfileSetAuth gives error about vpp-agent HOT 11 CLOSED

Does your code work with some other request? Try using simple request like vpe.ShowVersion to ensure that you are properly connecting to VPP binary API.

from vpp-agent.

@ondrej-fabry, yes, code is working properly, moreover i am also calling this struct and it is working fine.
code:

 req:=&ipsec.Ikev2ProfileAddDel{
                Name : []byte(ikev.Name),
                IsAdd : 1,
        }
 reply := &ipsec.Ikev2ProfileAddDelReply{}

        if err := ch.SendRequest(req).ReceiveReply(reply); err != nil {
                fmt.Println("ERROR:", err)
                return
        }
        if reply.Retval != 0 {
                fmt.Println("Retval:", reply.Retval)
                return
        }
        fmt.Printf("ikev2 add replace reply: %+v\n", reply)

Does VPP process print amything during request?

from vpp-agent.

@ondrej-fabry vpp process prints this:
vpp# Aborted (core dumped)

from vpp-agent.

Your VPP process crashed. You have most likely put some invalid values or unsupported combination in the request and this caused some undefined behavior and the process crash.

How do you run VPP? As a service? Try running it in foreground so you can see all of it's output. It might print some information before the crash. You can also configure output log file for the VPP using unix { log xxx ... }.

from vpp-agent.

@ondrej-fabry Log file is not showing anything, whenever i pass some configurations via govpp.its only show those commands which i set from vpp cli.
the output of log file is like:
2019/ 1/ 8 18:12:03:203: ***** Start: PID 926 *****

2019/ 1/ 8 18:14:55:494: ***** Start: PID 946 *****

can you tell me according to your understanding what is problem with this req:
req:=&ipsec.Ikev2ProfileSetAuth{
Name : []byte("Profile1"),
AuthMethod : uint8(2),
Data : []byte("vpp123"),
}
and how you will fill this struct?

from vpp-agent.

Please send your vpp.conf file you use for VPP process along with arguments you use please.

from vpp-agent.

@ondrej-fabry vpp.conf file contain:
unix {
nodaemon
cli-listen 0.0.0.0:5002
cli-no-pager
log /tmp/vpp.log
full-coredump
}
plugins {
plugin dpdk_plugin.so {
disable
}
}
api-trace {
on
}
command line arguments are:
vpp unix {log /conf.txt interactive }

from vpp-agent.

Does the IKEv2 work for you using CLI commands? As far as I know IKEv2 is not completely functional in VPP so I can't tell you if you can make it work at all. Try using CLI commands to set it up first.

Also why are you not running VPP using vpp -c /etc/vpp/vpp.conf and then run another shell with vppctl -s localhost:5002. That way when it crashes you might see some output in the first shell.

from vpp-agent.

@ondrej-fabry IKEv2 commands which i am using is working fine with cli.
in first shell i am getting this:
