Subject: Redirect packet back to host stack after AF_XDP?
Date: Wed, 14 Dec 2022 12:49:31 -0800	[thread overview]
Message-ID: <CAK3+h2xC1-5RgbT5FTKSMVopjHr_SuuU=E-bsvoCQYbVA5cn3w@mail.gmail.com> (raw)

Hi,

If I have an user space stack like mTCP works on top of AF_XDP as tcp
stateful packet filter to drop tcp packet like tcp syn/rst/ack flood
or other tcp attack, and redirect good tcp packet back to linux host
stack after mTCP filtering, is that possible?

Thanks

Vincent
