Repeat the haveged command will abort #29

After the haveged service was started, then repeat the haveged command : /usr/sbin/haveged -w 1024 -v 1 --Foreground The command will abort. The reason is that the "sys/entropy/haveged"socket is already used and can not create again, so cmd_listen return -1. But the program is not care about the error ,then FD_SET will raise abort.

Thanks for reporting it. We now disable command mode when there is another haveged instance already running.

@jirka-h hi, why can't just error_exit when socket_fd < 0? With the community's patch, haveged will be waiting after input "/usr/sbin/haveged -w 1024 -v 1 --Foreground".
