Define KF_IMPLICIT_PROG_AUX_ARG and handle it in the BPF verifier. The mechanism of patching is exactly the same as for __prog parameter annotation: in check_kfunc_args() detect the relevant parameter and remember regno in cur_aux(env)->arg_prog. Then the (unchanged) fixup_kfunc_call() adds a mov instruction to set the actual pointer to prog_aux. The caveat for KF_IMPLICIT_PROG_AUX_ARG is the implicitness. We have to separately check that the number of arguments is under MAX_BPF_FUNC_REG_ARGS. Signed-off-by: Ihor Solodrai <ihor.solodrai@linux.dev>
