siper

Siper Shield Siper는 Go와 C eBPF로 구축된 고성능 XDP 기반 IP 블랙리스트 방화벽입니다. 악성 트래픽을 Linux 네트워킹 스택에서 가장 초기 단계인 네트워크 드라이버 수준에서 차단할 수 있습니다. XDPExpress Data Path를 활용하여 Siper는 패킷이 커널의 무거운 네트워킹 서브시스템에 도달하기 전에 처리하므로, 심각한 DDoS 조건에서도 극한의 성능을 제공합니다. 특징 XDP 기반 성능 : 패킷 필터링이 NIC 드라이버 수준에서 XDPDROP을 사용하여 이루어지므로 iptables나...

CVE-2026-64352

CVE-2026-64352 affects the Linux kernel BPF subsystem , specifically the LPM (Longest Prefix Match) trie implementation in kernel/bpf/lpm_trie.c. The root cause is incorrect RCU lock annotations : trie_lookup_elem() used rcu_read_lock_bh_held() which does not accept the Tasks Trace RCU held by sl...
