attack plane? what attack do you see and how config helps?
I think all testing features are not required to be compiled
for a production system. A feature which should never be used
looks dangerous to me.
It is required on production system, since xdp testing and
xdp production has to use the same kernel. We cannot
keep rebooting the server back and forth to test and then to run.
It's not testing the kernel features, it's testing bpf programs
which are technically user space components.
Okay. Now I understand it is a production feature.
Thank you.
