Author SHA1 Message Date
Victor Julien 06904c9024 App Layer cleanup 
Removal of per flow 'aldata' array. It contained a ptr for each ALPROTO. Instead now we have 2 ptrs in the flow: alparser and alstate.
Various cleanups and dead code removal from the app layer API.
Should safe 100+ bytes memory per flow on 64 bit.
Updated lots of unittests to reflect these changes.

Victor Julien 8fa5a2c025 Split applayer and raw stream reassembly 
Split stream reassembly in 2 parts: a part that sends ack'd data to the app
layer parsers as soon as it's available, and another part that queues up
data into larger chunks for raw inspection.

Victor Julien 9f95ab7441 Make sure a stream that has a failing app layer inspection module no longer stops reassembly, but only app layer inspection. This way we can continue to inspect the reassembled stream. 15 years ago
Victor Julien 81f2499834 Store stream msgs processed by the app layer in the tcp session so they can be inspected by the detection module as well. The detection module returns them to the pool. 15 years ago

Victor Julien 301522f316 Add TCP_GET_WSCALE macro for easy access to wscale. Update StreamTcp to use it. Default to wscale 14 (max) in case of midstream as there seems to be no reliable way to predict wscale if we missed it. 16 years ago

Victor Julien b102ea2123 Big update: 
- Implement "closing" state in flow.
- Add protocol specific timeouts.
- Lots of stream tracking updates, fixing a lot of out of window issues.
- Stream reassembly fixes.
- Implement a new IDS runmode with 4 stream and detect threads.
- Added a BUG_ON macro that aborts the engine if the expression is true.
- Better balance the flow queue handler for traffic that doesn't have flow (like icmp currently).
- Simplify application level protocol in the Tcp Session.
- Add some debugging memory counters.
