程序偶尔会崩溃 #3

Closed pexcn closed 1 year ago

pexcn commented 1 year ago

我把 kcptun-libev 封装成了一个 docker 镜像，今天无意中发现它的启动时间是十几个小时之前，而我部署完之后很久都没有动过这个容器，所以应该是程序崩溃导致容器自动重启了。麻烦作者排查一下😄

关键日志：

Assertion failed: ("libev: I/O watcher with invalid fd found in epoll_ctl", errno != EBADF && errno != ELOOP && errno != EINVAL) (ev_epoll.c: epoll_modify: 134)

具体的日志如下：

未加密情形下的协议安全暂无计划支持，请在安全的场景中使用未加密模式

kcptun-libev 转发的是 shadowsocks 的端口，而 shadowsocks 的端口是已经加密的了，这样不是相当于已经加密了吗？😅

攻击面取决于直接暴露于公网的服务。截至v2.0.1，kcptun-libev直接暴露于公网时，不适合使用未加密模式。
