Anoop Saldanha	429c6388f6	App layer API rewritten. The main files in question are: ... app-layer.[ch], app-layer-detect-proto.[ch] and app-layer-parser.[ch]. Things addressed in this commit: - Brings out a proper separation between protocol detection phase and the parser phase. - The dns app layer now is registered such that we don't use "dnstcp" and "dnsudp" in the rules. A user who previously wrote a rule like this - "alert dnstcp....." or "alert dnsudp....." would now have to use, alert dns (ipproto:tcp;) or alert udp (app-layer-protocol:dns;) or alert ip (ipproto:udp; app-layer-protocol:dns;) The same rules extend to other another such protocol, dcerpc. - The app layer parser api now takes in the ipproto while registering callbacks. - The app inspection/detection engine also takes an ipproto. - All app layer parser functions now take direction as STREAM_TOSERVER or STREAM_TOCLIENT, as opposed to 0 or 1, which was taken by some of the functions. - FlowInitialize() and FlowRecycle() now resets proto to 0. This is needed by unittests, which would try to clean the flow, and that would call the api, AppLayerParserCleanupParserState(), which would try to clean the app state, but the app layer now needs an ipproto to figure out which api to internally call to clean the state, and if the ipproto is 0, it would return without trying to clean the state. - A lot of unittests are now updated where if they are using a flow and they need to use the app layer, we would set a flow ipproto. - The "app-layer" section in the yaml conf has also been updated as well.	12 years ago
Victor Julien	3e604b8703	pcre: parsing cleanup ... Remove all flags indicating the buffer type. They were only used at parse time. Because of this the DetectPcreData_ structure could shrink to 32 bytes.	12 years ago
Eric Leblond	cd3e32ce19	unittests: some functions needs a flow lock. ... In debug validation mode, it is required to call application layer parsing and other functions with a lock on flow. This patch updates the code to do so.	12 years ago
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
Anoop Saldanha	4c6efa2d40	Update content id assignment. ... All fp id assignment now happens in one go. Also noticing a slight perf increase, probably emanating from improved cache perf. Removed irrelevant unittests as well.	13 years ago
Anoop Saldanha	f8ae53ac02	Further customize content modifier buffer registration. ... Allow modifier setups functions to have CustomCallbacks to enable their internal conditions.	13 years ago
Anoop Saldanha	a304a98d1d	http_* setup unified.	13 years ago
Anoop Saldanha	0b5d277254	code cleanup for all content based keywords.	13 years ago
Anoop Saldanha	a308d718ae	Allow the use of relative without the presence of a related previous keyword.	13 years ago
Anoop Saldanha	66f3c37016	code cleanup + unittests added against http_host and http_raw_host keywords, ... against various combinations of hostname in uri and host header.	13 years ago
Anoop Saldanha	3511f91bba	Add support for the new keyword - http_raw_host header. ... The corresponding pcre modifier would be 'Z'.	13 years ago
