根据 socket 对象找到另一端,直接把 skb 给放到对端的接收队列里了 接收函数主题是 unix_stream_recvmsg,这个函数中只需要访问它自己的接收队列就行了,源码就不展示了。所以在本机网络 IO 场景里,基于 Unix Domain Socket 的服务性能上肯定要好一些的。 四、性能对比 为了验证 Unix Domain Socket 到底比基于 127...
* 错误消息,需要设置IP_RECVERR套接字选项,之后可通过参数 * flags为MSG_ERRQUEUE的recvmsg系统调用来获取详细的出错 * 信息。 * UDP套接字和RAW套接字在调用recvmsg接收数据时,可以设置 * MSG_ERRQUEUE标志,只从套接字的错误队列上接收错误而不 * 接收其他数据。实现这个功能是通过ip_recv_error()来完成的。
