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.

I suggest adding a CONFIG option like CONFIG_BPF_PROGRAM_TEST_RUN
to control whether the kernel should be compiled with this feature
or not. We can enable by default, and give people a chance to
turn it off. At least in my company people tends to turn all
unneeded features off. If you don't provide a config option they
will make one by themselves.

Thank you.
