Hi Quinn,
I've checked BSDLLCTest
already, I think the question is PF_NDRV
requires root privileges,
we can not ask common users to run
applications with root account as usual. We need
another
way to slove it.
Maybe we can open the
socket in the kernel space, such as in a socker filter, and acces the
filter
in the user space, we can avoid the privileges
problem.
How about your
ideas?
Thanks.
Regards,
Robin
