The crash is in the last lua_rawset call in socket_lock. I suppose it has something to do with there not existing a script thread at the time the prerule is called. It seems like you should be able to use a socket in a prerule, though. Is there a good fix for this?
Early on I (?) decided to not allow socket connections in rule functions. The reason for that is NSE isn't structured to loop over rule functions which have made connections. That is, if a rule function yields, then NSE must resume it when the socket operation is complete and get the rule function result. I think rule functions need to be short and simple or every script is blocked in the rule evaluation step. _______________________________________________ Sent through the dev mailing list http://nmap.org/mailman/listinfo/dev Archived at http://seclists.org/nmap-dev/
