Victor Julien 8b30226914 Detection keyword cleanup 17 years ago
Victor Julien b259e362cd Convert uricontent to use new scanning methods as well. Move http_method and http_cookie keywords out of pmatch list for now. 17 years ago

Pablo Rincon 38dc7ffebc Adding settings for detect engine group config 17 years ago
Anoop Saldanha 8cf60d6645 Changed the way cuda dispatcher passes back results. Now each detection thread has it's own queue to which the dispatcher can pump packets back to the detect thread. Also, with cuda enabled and a non-cuda mpm being used, we won't create a dispatcher and instead call the b2g scan/search funtions directly instead of using the dispatcher. 17 years ago

Victor Julien d5c732f1f9 Add tag keyword stub 17 years ago
Victor Julien 4824868766 Application layer detection improvements 
- improve locking of application layer handling, making sure that the flow cannot be freed/cleared when the detection engine is still working with it.
- add a check to the app layer detection to make sure that a match function will only inspect an app layer state if it's of the right type.

Victor Julien 9fd46e9425 Support for sigs with both pkt and applayer detect 
Sets a flowbit with the sig id if the packet matches match. Checks
on that if the app layer matches match. Currently misuses the
flowbits api for this in a way that needs fixing.
