It isn't clear for me what can be done to protect the whole system inside syslogd. Does anybody knows what SuSE really changed? Their source package isn't very helpful.
There were two notable problems 1. Syslogd defaulted to stream sockets which means you have resource control problems - in fact Dan Bernstein posted some very good stuff about that issue about a year ago 2. The client code decided it would be a good idea to wait - ie do a blocking connect. Unfortunate it someone ate all the syslog handles With a datagram system it comes down to losing messages under load. I think that is about as good as you can get. Alan
