Thanks for working on this. Strange thing is that I didn't manage to see the crash on 6.16.0-rc6, 6.17.0-rc3 or 6.18.0-rc1 that is the latest. I feel that your environment is hugely different from mine. I followed your steps you attached in your code: ////// gcc xskInt.c -lxdp ////// sudo ip link add veth1 type veth ////// sudo ip link set veth0 up ////// sudo ip link set veth1 up ////// sudo ./a.out The version of libxdp that I use is 1.4.2, BTW. Could you share me with your .config? I'm not sure if I missed something. Thanks, Jason
