Victor Julien	077970051e	file-data: implement relative pcre support.	14 years ago
Victor Julien	89f83e714c	Introduce http_server_body keyword. ... The http_server_body content modifier modifies the previous content to inspect the normalized (dechunked, unzipped) http_server_body. The workings are similar to http_client_body. Additionally, a new pcre flag was introduced "/S". To facilitate this change the signature flags field was changed to be 64 bit.	14 years ago
Victor Julien	3009429e3c	HTTP transaction handling improvement ... In some cases AppLayerTransactionGetInspectId can return -1, which is now handled by all it's callers. Improve logic of selecting which transactions are inspected by the various HTTP keywords.	14 years ago
Victor Julien	66a3cd96a8	Prepare HTTP response body tracking.	14 years ago
Anoop Saldanha	9a6aef459e	modify all relevant app layer API calls to accomodate passing parser local storage argument	14 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. 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.	14 years ago
Anoop Saldanha	ed3b44b3b5	fix parsing content keywords. We are more strict now. All content keywords need to be enclosed in double quotes. Better validation for sid, priority and rev keywords	14 years ago
pilcrow	f5017e0d1a	Always try PCRE_NO_AUTO_CAPTURE first for signature regexes. ... Many, many pcre: signatures specify (...) when the more efficient (?:...) is all that is needed. This change attempts to force PCRE_NO_AUTO_CAPTURE on all unnamed capture groups, reverting to capturing when necessary, e.g., when \1 is referenced.	14 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. Other modifications: - Generalize transaction tracking, logging and inspection. - Adapt http and dcerpc to use the new transaction handling. - Stream engine now always notifies app layer of a stream eof.
