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.
