linnix

Linnix 找出哪个进程正在损害你的SLO——不仅仅是哪个进程正在使用CPU，而是哪个进程正在导致停滞。 问题 top显示80%的CPU。Prometheus显示高延迟。但 哪个Pod 实际上正在拖慢你的支付服务？ Linnix使用eBPF + PSI（压力停滞信息）来解答这一问题。PSI测量实际的停滞时间——不是使用率，而是争用。一个使用40% CPU且PSI为60%的Pod比一个使用100% CPU但PSI为5%的Pod更糟。 Linnix检测的内容： 嘈杂邻居 ：哪个容器在导致其他容器资源饥饿 Fork风暴 ：在节点崩溃前失控的进程创建 停滞归因 ：“Pod X 导致 Pod Y...

CVE-2026-74594

A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists where a timer rtpolltimer can be re-armed after it has been deleted during the destruction of a control group cgroup.
