From: Yang Bo <bo@xxxxxxxx> We (the antgroup) has a requirement to manipulate global variables. The platform to manage bpf bytecode has no idea about varaibles' type/size/address. It only has some strings (like key = value) passed from admin. We find a way to parse BTF and then query/update the variables. There may be better ways to do it. This approach is what we can find for now.
