Anoop Saldanha	d4d18e3136	Transaction engine redesigned. ... Improved accuracy, improved performance. Performance improvement noticeable with http heavy traffic and ruleset. A lot of other cosmetic changes carried out as well. Wrappers introduced for a lot of app layer functions. Failing dce unittests disabled. Will be reintroduced in the updated dce engine. Cross transaction matching taken care of. FPs emanating from these matches have now disappeared. Double inspection of transactions taken care of as well.	13 years ago

Victor Julien	18d79c4215	file store: respect flowbits and other keywords ... The filestore keyword until now flagged a file, tx or ssn for storage as soon as the keyword was inspected. This happens before flowbits and some other keywords, so files were stored that weren't supposed to. This patch makes the filestore keyword fill an array in the detect engine thread ctx. Then if the full signature matches, a post-match filestore function makes the store final.	14 years ago
Victor Julien	9878eca086	file handling: expand filestore keyword ... Filestore keyword by default (... filestore; ... ) marks only the file in the same direction as the rule match for storing. This makes sense when inspecting individual files (filemagic, filename, etc) but not so much when looking at suspicious file requests, where the actual file is in the response. The filestore keyword now takes 2 optional options: filestore:<direction>,<scope>; By default the direction is "same as rule match", and scope is "currently inspected file". For direction the following values are possible: "request" and "to_server", "response" and "to_client", "both". For scope the following values are possible: "tx" for all files in the current HTTP/1.1 transation, "ssn" and "flow" for all files in the session/flow. For the above case, where a suspious request should lead to a response file download, this would work: alert http ... content:"/suspicious/"; http_uri; filestore:response; ...	14 years ago
