Sorry let me clarify this line here:
"...at the time, I was running an older version 8.0.x so I recompiled all the ngcp packages under this kernel and completed the installation without issues.."
8.0.x is the older ngcp version. I recompiled version 9.0.1.0 under that new kernel version 5.3.0-1035-aws #37-Ubuntu

Thanks Alex.
So it turns out my rtpengine stopped working after our latest kernel upgrade to:
Linux sjomainrtpe30 5.3.0-1035-aws #37-Ubuntu SMP Sun Sep 6 01:17:09 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
at the time, I was running an older version 8.0.x so I recompiled all the ngcp packages under this kernel and completed the installation without issues.
As soon as we started making test calls, I received 0 audio from those test endpoints. Looking at the rtpengine logs, I see several messages that's quite concerning:
Sep 11 18:43:41 sjomainrtpe30 kernel: [ 13.434623] xt_RTPENGINE: loading out-of-tree module taints kernel. Sep 11 18:43:41 sjomainrtpe30 kernel: [ 13.434670] xt_RTPENGINE: module verification failed: signature and/or required key missing - tainting kernel Sep 11 18:43:41 sjomainrtpe30 kernel: [ 13.434938] Registering xt_RTPENGINE module - version 9.0.1.0+0~mr9.0.1.0
and
Sep 11 18:49:50 sjomainrtpe30 rtpengine[1030]: WARNING: [2-7859@2600:1f1c:4ff:3e01:f64d:2f67:c0fa:c931 port 50000]: No support for kernel packet forwarding available (decryption cipher or HMAC not supported by kernel module)
which I assume is due to the first error I pasted.
So I tried
- rebooting the system which maybe the module wasn't loaded properly.
- I reran modprobe to make sure the module is installed
- I ran some dkms command to see if any error pop up due to the kernel
version I'm running and I see no errors:
dkms status falco, 0.20.0+d77080a, 5.3.0-1032-aws, x86_64: installed falco, 0.20.0+d77080a, 5.3.0-1035-aws, x86_64: installed ngcp-rtpengine, 9.0.1.0+0~mr9.0.1.0, 5.3.0-1032-aws, x86_64: installed ngcp-rtpengine, 9.0.1.0+0~mr9.0.1.0, 5.3.0-1035-aws, x86_64: installed
So I'm running out of options.
Any advice?

There is an RTPEngine mailing list, I believe, but RTPEngine questions are often posed here given its close association with Kamailio. What's going on?

Hey guys,
Is this the right place to ask about rtpengine (ngcp) related issues with kernel packet forwarding?
Thanks.
