Description
**errors occur as follow:**
bpf: Failed to load program: Permission denied
0: (b7) r2 = 44
1: (7b) *(u64 *)(r1 +0) = r2
invalid bpf_context access off=0 size=8
It seems that I can not modify the registers when the arguments passing by registers, since the verifier would refuse.
I just do this in test environment. How can I do? thranks.
