Commit 812c1057 introduced HUP detection on unix and tcp sockets prior to a read in tcp_chr_read. This unfortunately broke CloudStack 4.2 which relied on the old behaviour where data on a socket was readable even if a HUP was present. A working solution is to properly check the return values from recv, handling a closed socket once there is no more data to read. Also enable polling for G_IO_NVAL to ensure the callback is called for all possible events as these should now be possible to handle with the improved error detection.
