Anoop Saldanha	eade60f0fd	make some name changes. break PopulateMpm(). Set the avoid mpm double check flags	15 years ago
Anoop Saldanha	4883efd0f6	unifying content structure - uricontent now uses DetectContentData	15 years ago
Anoop Saldanha	3c73854d2d	completely remove populate_mpm_flags. Some indentation changes. Also disable support to avoid double checks inside payload inspection for patterns added to mpm. Also add support to MpmFactory to reclaim a mpm_ctx	15 years ago

Anoop Saldanha	e072841e93	hash fix in staging to differentiate nocase duplicate patterns from case-senstive ones	15 years ago
Anoop Saldanha	29b5cb9abd	respect content flags in hash compare function during staging. For example, we would end up ignoring a nocase version of a duplicate content from another sig in the same sgh	15 years ago
Anoop Saldanha	0ef684705c	support single mpm context distribution across sghs in staging. Also see to it that ac works fine with this setup	15 years ago
Anoop Saldanha	658ff5753d	aho-corasick for the cpu. We have 2 versions of ac. The first MPM_AC uses the delta table and the secone one MPM_AC_GFBS uses the goto-failure table	15 years ago
Victor Julien	5a7efe5f97	Add comment and layout update to new fast_pattern code.	15 years ago

Victor Julien	0219b767b8	Fix a content pattern matching bug related to signature grouping and mpm_ctx sharing. In certain conditions (signature combinations) the mpm_stream_ctx (the ctx that handles stream pattern scanning) wasn't properly setup.	15 years ago

Victor Julien	a3ff0e7210	Don't scan TCP packet payload if it was added to the stream. Inspect the tcp stream with the correct packet. Should fix #184 and #185.	15 years ago
Victor Julien	b8fec77f37	Fix tcp connections that are reset (RST packet) not always inspecting the reassembled stream. Update transaction id code to make sure both directions of a transaction are inspected before incrementing the inspect_id.	15 years ago

Anoop Saldanha	30940c9a94	pack all the packet pattern scan and search packet setup for cuda into a function inside util-cuda-handlers.[ch]	16 years ago
Anoop Saldanha	8cf60d6645	Changed the way cuda dispatcher passes back results. Now each detection thread has it's own queue to which the dispatcher can pump packets back to the detect thread. Also, with cuda enabled and a non-cuda mpm being used, we won't create a dispatcher and instead call the b2g scan/search funtions directly instead of using the dispatcher.	16 years ago
