Eric Leblond	e176be6fcc	Use unlikely for error treatment. ... When handling error case on SCMallog, SCCalloc or SCStrdup we are in an unlikely case. This patch adds the unlikely() expression to indicate this to gcc. This patch has been obtained via coccinelle. The transformation is the following: @istested@ identifier x; statement S1; identifier func =~ "(SCMalloc|SCStrdup|SCCalloc)"; @@ x = func(...) ... when != x - if (x == NULL) S1 + if (unlikely(x == NULL)) S1	13 years ago

Victor Julien	262a7300d7	flow: shrink Flow datatype ... Introduce a separate FlowAddress structure for holding the ipv4 or ipv6 address that doesn't have the family in it like the Address structure. Instead, the family is stored in the flow as a flag: FLOW_IPV4 and FLOW_IPV6. Add macro's to check the family, copy the address, etc. Update many unittests to reflect these changes. Introduce unittest helper functions for creating and initializing a flow and freeing it again. On 64 bit this shrinks the flow with 8 bytes.	14 years ago
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.

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.	15 years ago

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	70b32f7380	First stab at creating a stateful detection engine. ... Stateful detection for app layer detection keywords, except uricontent. Stores it's partial results in the flow structure.

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.	16 years ago
