报文中掺杂额外字节

8

hi，我正在开发一个基于kcp的应用，使用rsock做隧道，发现rsock会塞一段“不是我发送的字节”到udp包中。 客户端macos，服务端linux，版本均为20180613_03 tcpdump抓包发现，偶尔会有一段我没有发送的字节掺杂到报文中： 每一行是一次抓到的多余报文，特征很明显： ``` f268b10bd0083eed1700b6bc82180c30f129d9000000b6db1a370000000000 f268b10bd0083eed1700b6bc82180c30f129e400000045e318370000000000 f268b10bd0083eed1700b6bc82180c30f129f200000083e517370000000000 f268b10bd0083eed1700b6bc82180c30f1290101000019e719370000000000 f268b10bd0083eed170089aac51cc4d6d8a510000000a5e9895e0000000000 ``` 你们看下是否需要我提供tcpdump文件？或者说这段报文是有什么特殊用途的，需要我应用层单独处理？

Time wheel implementation required

目前的定时任务是通过PriorityQueue维护的，考虑换成时间轮。 由于常见的TCP超时时间是15分钟（例如LVS），而UDP则更短，一般认为不会出现超过15分钟的定时任务 使用4层时间轮，每层32个元素。可以表示`32^4=1048576 ms > 15 minutes`。使用链表维护同一毫秒的定时任务列表。使用32是因为`%`操作可以优化为`&`操作 不需要考虑并发，时间事件的访问总是在eventloop里面进行的。 对于超过`1048576ms`的定时任务，放在PriorityQueue中排序，当时间低于`1048576 ms`时从队列中挪出来放进时间轮里。 需要实现的接口：[TimeQueue.java](https://github.com/wkgcass/vproxy/blob/dev/base/src/main/java/vproxybase/util/time/TimeQueue.java)和[TimeEvent.java](https://github.com/wkgcass/vproxy/blob/dev/base/src/main/java/vproxybase/util/time/TimeElem.java)

Unable to compile native-image when `allow-native-access` is true

It seems that `Linker.Option.critical(true)` is not supported by native-image, at least on `macOS x86_64`. I made a small project to reproduce this issue: [a.tar.gz](https://github.com/user-attachments/files/15849481/a.tar.gz) You will need to modify `JAVA_HOME`...
