[BUG] PDU Session Establishment Reject for PDU Session ID 1, 5GSM Cause: Service option temporarily out of order about packetrusher HOT 10 CLOSED

The following command fixed the VRF module:

sudo apt-get install linux-modules-extra-$(uname -r)

I already used the above command before seeing your comment, not sure if the command you suggested will fix it.

PDU session is now okay..

Hi @linouxis9 @infinitydon

The following was not required when installing PacketRusher on Ubuntu 22.04.

apt-get install linux-modules-extra-$(uname -r)

My OS is as follows. gtp5g kernel module also worked.

Linux pr10 5.15.0-89-lowlatency #99-Ubuntu SMP PREEMPT Thu Nov 2 15:27:06 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

FYI.

from packetrusher.

I do seem to have issues with gtp5g when using an even more recent kernel (6.5.0 for example).

Ubuntu 22.04 GA kernel is 5.15.
gtp5g is working so far.

Ubuntu 22.04 HWE kernel is 6.2.
gtp5g does not support 6.2 kernel.
https://forum.free5gc.org/t/upf-est-createfar-error-invalid-argument/2111/2?u=yoursunny

Thus, we must resist the urge of installing HWE kernel.

Hi @infinitydon!
Thank for your report once again :-) I can reproduce your issue, but I think this time, the issue might be on open5gs' side not yet handling well slices when doing roaming, or an open5gs' configuration issue, rather than a PacketRusher's issue.

I was able to make it work by not using ssd in the open5gs's amf configuration:

  plmn_support:
    - plmn_id:
        mcc: 001
        mnc: 01
      s_nssai:
        - sst: 1

and setting inside PacketRusher:

gnodeb:
...
  slicesupportlist:
    sst: "01"
    sd: "ffffff"
...
ue:
...
  snssai:
    sst: 01
    sd: "ffffff"

sd being set as ffffff equals to no sd, I'll improve configuration that if sd is not set then "ffffff" will be automatically set.
Could you confirm that it work in your environment when not using Slice Differentiator?

Also the number of retries from pack-rusher seems to be too much, it practically flooded the logs of the Open5gs core components when it encountered this issue, I think this should be reduced to a few seconds retry mechanism.

I completely agree, will work on that, thanks!

Also I think the Discussion feature of your github repo should be enable so as to deal with other issues that are not related to bugs or feature (this is just a suggestion)

Will do as well :-)

Thanks a lot for using PacketRusher!

@linouxis9 - I just tried that but now getting the following error in packet-rusher:

INFO[0001] [UE][NAS] Receive DL NAS Transport
INFO[0001] [UE][NAS] Receiving PDU Session Establishment Accept
FATA[0002] [UE][DATA] Unable to create VRF for UEoperation not supported

sudo modprobe vrf

And then re-try again. Make sure your kernel supports vrf as well (on Ubuntu, you should use the generic kernel).
Will add to the installation guide, thanks!

Looks like VRF is not included in my kernel

ubuntu@packetRusher:~/rusher-raoming-1$ sudo modprobe vrf
modprobe: FATAL: Module vrf not found in directory /lib/modules/5.4.0-167-generic
ubuntu@packetRusher:~/rusher-raoming-1$

ubuntu@packetRusher:~/rusher-raoming-1$ uname -r
5.4.0-167-generic

Which kernel version are you using with Ubuntu 20.04

Can you try to install HWE kernel?

sudo apt install --install-recommends linux-generic-hwe-20.04 

from packetrusher.

Glad that I could help! I'll update the installation guide and implement your suggestions.
Thanks :-)

Hi @s5uishida,
Thanks for the information! PacketRusher seems indeed to work on Ubuntu 22.04. However, I do seem to have issues with gtp5g when using an even more recent kernel (6.5.0 for example).
