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.	13 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.	13 years ago
Anoop Saldanha	48cf0585fb	Suricata upgrade to libhtp 0.5.x. Remove the support for now unsupported personalities from libhtp - TOMCAT_6_0, APACHE and APACHE_2_2. We instead use the APACHE_2 personality.	13 years ago
Anoop Saldanha	ab4b15c2e7	fix for #788 . Now depth is kept in mind when we inspect chunks in client/server body. This takes care of FPs originating from inspecting subsequent chunks that match with depth, but shouldn't.	13 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	b99f9fe890	New app inspection engine introduced. Moved existing inspecting engines to use it.	14 years ago
Anoop Saldanha	7b4eac3e8d	Change all inspect callbacks to accept TV and a tx_id param.	14 years ago
Victor Julien	19a7e7f395	flow: create a flow lock macro API, implement it for mutex and rwlocks. Mutex remains the default.	15 years ago
Anoop Saldanha	603d4a719a	remove det_ctx->payload_offset and use det_ctx->buffer_offset. Update hscd and hsmd to use the new generic content inspection engine	15 years ago
Anoop Saldanha	0677190960	rebase commit for hscd and hsmd patches	15 years ago
Anoop Saldanha	22b1f5b22b	fix seg fault due to wrong sm list access in hscd	15 years ago
Anoop Saldanha	09313cf9bd	Support http stat code detection engine, fast pattern(mpm engine included). Fix http stat code setup function. Fix pcre option for stat msg keyword. With this the pcre options for server_body is Q, for stat_msg is Y and for stat_code is S	15 years ago
