Jiri Olsa 65eb006d85 bpf: Move kernel test kfuncs to bpf_testmod ... Moving kernel test kfuncs into bpf_testmod kernel module, and adding necessary init calls and BTF IDs records. We need to keep following structs in kernel: struct prog_test_ref_kfunc struct prog_test_member (embedded in prog_test_ref_kfunc) The reason is because they need to be marked as rcu safe (check test prog mark_ref_as_untrusted_or_null) and such objects are being required to be defined only in kernel at the moment (see rcu_safe_kptr check in kernel). We need to keep also dtor functions for both objects in kernel: bpf_kfunc_call_test_release bpf_kfunc_call_memb_release We also keep the copy of these struct in bpf_testmod_kfunc.h, because other test functions use them. This is unfortunate, but this is just temporary solution until we are able to these structs them to bpf_testmod completely. As suggested by David adding bpf_testmod.ko make dependency for bpf programs, so they are rebuilt if we change the bpf_testmod.ko module. Also adding missing __bpf_kfunc to bpf_kfunc_call_test4 functions.
