WebNetfilter是 Linux 内核中进行数据包过滤，连接跟踪（Connect Track），网络地址转换（NAT）等功能的主要实现框架；该框架在网络协议栈处理数据包的关键流程中定义了一系列钩子点（Hook 点），并在这些钩子点中注册一系列函数对数据包进行处理。 WebThis allows userspace ("nft list hooks") to show which bpf program is attached to which hook. Without this, user only knows bpf prog is attached at prio x, y, z at INPUT and FORWARD, but can't tell which program is where. richer poorer discountWeb目前我们主要处理IPv4，所以该参数总是PF_INET； hooknum：钩子函数的挂载点，即HOOK点； priority：优先级。前面也说过，一个HOOK点可能挂载了多个钩子函数，当Netfilter在这些HOOK点上遍历查找所注册的钩子函数时，这些钩子函数的先后执行顺序便由该参数来制定。 richer-poorer discount code
