Hi,
Is it possible for a netfilter hook registered during module insertion
time to be removed by a userspace application (such as iptables) without
the insertion of a new module?
What I am trying to do is implement a hook for secure packet processing
using netfilter. If however an attacker can remove this hook without
inserting a new module or compromising the kernel in some way then the
security level of this hook is compromised.
--Thanks and Regards,
