Subject: [PATCH 0/2] Add api to manipulate global varaible
Date: Mon, 5 Jun 2023 16:57:31 +0800 [thread overview]
Message-ID: <20230605085733.1833-1-yb203166@antfin.com> (raw)
From: Yang Bo <bo@hyper.sh>
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.
Yang Bo (2):
Add api to manipulate global variable
mini test case.
