siper

Siper（盾牌） Siper 是一款高性能、基于 XDP 的 IP 黑名单防火墙，使用 Go 和 C（eBPF）构建。它允许你在 Linux 网络栈的最早阶段——网络驱动程序级别——丢弃恶意流量。通过利用 XDP（快速数据路径），Siper 在数据包甚至到达内核繁重的网络子系统之前就对其进行处理，从而在重 DDoS 条件下提供极致性能。 特性 XDP 驱动性能 ：使用 XDPDROP 在 NIC 驱动级别进行数据包过滤，相比 iptables 或 nftables，CPU 开销显著降低。 LPM（最长前缀匹配） ：通过专用的 BPF LPM Trie 映射支持基于 CIDR 的阻止（例...
