Read returning -1 is an error here so make sure to print the actual reason and close the socket. Before this patch we just looped over the fd with read returning -1 every time. EINTR is handled to not cause an error and we don't need to check EAGAIN/EWOULDBLOCK since the callback is only called in case there is something to read. To avoid copy&paste issues the check is implemented as a macro and the log message moved into a separate if.
