Hi, I have 3 Unix dgram sockets (sockA, sockB, sockC): - sockA is connected to sockB. - sockB is connected to sockC. - sockC is not connected. SockA cannot send any message to sockB because net/unix/af_unix.c::unix_may_send() prevents it. Is there any reason for that restriction?
Yes, absolutely. When you connect() a socket, you expect to only *receive* packets from the specified peer. -- Rémi Denis-Courmont http://www.remlab.net/ http://fi.linkedin.com/in/remidenis
