Victor Julien 580b09c2b8 Make sure we inspect all outstanding reassembled stream chunks (smsg) if the stream is shutting down. Make sure to do inspect signatures that use dsize against the tcp packet payload, even if that payload was already added to the stream. Likewise, the dsize signatures are not inspected against the reassembled stream. 16 years ago
Victor Julien b8fec77f37 Fix tcp connections that are reset (RST packet) not always inspecting the reassembled stream. Update transaction id code to make sure both directions of a transaction are inspected before incrementing the inspect_id. 16 years ago

Victor Julien 6a53ab9c5a Stream engine memory handling update
The stream engine memory handling needed updating as it didn't scale. Changes:

- pools can now be initialized to size 0, meaning unlimited
- stream engine uses a memcap setting. Sessions, segments and aldata is part
  of this, app layer state isn't.
- memory is accounted using a global int that is spinlocked.
- a counter for sessions that have not been picked up because of memcap was
  added.
- all reassembly errors are converted to debug msgs.

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.
