Victor Julien	5bde86b0e8	detect-engine: new registration call ... Make it more in line with MPM registration.	9 years ago
Victor Julien	5f994756e6	detect-engine: improved inspect engines ... Inspect engines are called per signature per sigmatch list. Most wrap around DetectEngineContentInspection, but it's more generic. Until now, the inspect engines were setup in a large per ipproto, per alproto, per direction table. For stateful inspection each engine needed a global flag. This approach had a number of issues: 1. inefficient: each inspection round walked the table and then checked if the inspect engine was even needed for the current rule. 2. clumsy registration with global flag registration. 3. global flag space was approaching the need for 64 bits 4. duplicate registration for alprotos supporting both TCP and TCP (DNS). This patch introduces a new approach. First, it does away with the per ipproto engines. This wasn't used. Second, it adds a per signature list of inspect engine containing only those engines that actually apply to the rule. Third, it gets rid of the global flags and replaces it with flags assigned per rule per engine.	9 years ago
Victor Julien	f1e3840516	http_response_body: implement keyword with mpm ... Implemented as 'stickybuffer'.	9 years ago
Victor Julien	4c98b6cef3	http_request_line: implement keyword and mpm ... Implemented as 'stickybuffer'. Move all logic into the keyword file and remove bad tests that tested URI instead of request line.	9 years ago
Victor Julien	5b2e36a1b0	mpm: add App Layer MPM registery ... Register keywords globally at start up. Create a map of the registery per detection engine. This we need because the sgh_mpm_context value is set per detect engine. Remove APP_MPMS_MAX.	9 years ago
Victor Julien	125603871b	detect: config opt to enable keyword prefilters	9 years ago
Victor Julien	17bc0299fe	detect: rename non_mpm lists/vars to non_pf ... Rename to non_pf: non prefilter.	9 years ago
Mats Klepsland	dc8e0b3cf2	detect: add detect engine for tls validity keywords ... Add detect engine for tls validity keywords (tls_cert_notbefore and tls_cert_notafter).	9 years ago
Mats Klepsland	d91664d67a	detect-dns: move DetectEngineInspectGenericList to detect-engine.c ... Move DetectEngineInspectGenericList from detect-engine-dns.c to detect-engine.c to enable it to be used other places as well.	9 years ago
Mats Klepsland	4172c4c8ac	tls: add (mpm) keyword tls_cert_subject ... This keyword is a replacement for tls.subject.	9 years ago
Mats Klepsland	9b2717799c	tls: add (mpm) keyword tls_cert_issuer ... This keyword is a replacement for tls.issuerdn.	9 years ago
Victor Julien	215d0d54c7	detect: optimize rule address parsing ... Many rules have the same address vars, so instead of parsing them each time use a hash to store the string and the parsed result. Rules now reference the stored result in the hash table.	9 years ago
Eric Leblond	f2d1e93e65	unix-socket: add auto mode ... When running in live mode, the new default 'auto' value of unix-command.enabled causes unix-command to be activated. This will allow users of live capture to benefit from the feature and result in no side effect for user running in offline capture.	9 years ago
Victor Julien	b3b78d4326	detect: log earlier that rule reload is happening	9 years ago
Victor Julien	a88359dcf0	detect: get proper legacy custom values. Issue #1804	9 years ago
Victor Julien	b3bf7a5729	output: introduce config and perf output levels ... Goal is to reduce info output	9 years ago
Victor Julien	72d3ea6552	detect: make pattern matcher messages less verbose	9 years ago
Victor Julien	36535cbc61	yaml: remove conf_filename global ... conf_filename was a global pointer to the filename of the yaml. Move into SCInstance. This reduces it's scope and cleans up the code.	9 years ago
Justin Viiret	d807bf4e8a	detect-engine: log MPM/SPM matchers being used	9 years ago
Justin Viiret	c9d0d6f698	mpm: add "auto" default for mpm-algo ... Setting mpm-algo to "auto" will use "hs" if Suricata was built against Hyperscan, and "ac" otherwise (or "ac-tile" on Tilera platforms).	9 years ago
Victor Julien	e43ce0a9ec	file: switch to streaming buffer API ... Make the file storage use the streaming buffer API. As the individual file chunks were not needed by themselves, this approach uses a chunkless implementation.	9 years ago
Victor Julien	46e55f1e34	http body handling: use streaming buffer API ... Convert HTTP body handling to use the Streaming Buffer API. This means the HtpBodyChunks no longer maintain their own data segments, but instead add their data to the StreamingBuffer instance in the HtpBody structure. In case the HtpBodyChunk needs to access it's data it can do so still through the Streaming Buffer API. Updates & simplifies the various users of the reassembled bodies: multipart parsing and the detection engine.	9 years ago
Victor Julien	52d500c670	flowworker: initial support ... Initial version of the 'FlowWorker' thread module. This module combines Flow handling, TCP handling, App layer handling and Detection in a single module. It does all flow related processing under a single flow lock.	9 years ago
Mats Klepsland	a13df67864	detect: add (mpm) keyword for tls_sni ... Match on server name indication (SNI) extension in TLS using tls_sni keyword, e.g: alert tls any any -> any any (msg:"SNI test"; tls_sni; content:"example.com"; sid:12345;)	9 years ago
Justin Viiret	cce2d114e8	spm: add and use new SPM API ... This new API allows for different SPM implementations, using a function pointer table like that used for MPM. This change also switches over the paths that make use of DetectContentData (which previously used BoyerMoore directly) to the new API.	9 years ago
Justin Viiret	ce408c4d10	spm: add SinglePatternMatchDefaultMatcher ... Allows selecting SPM algorithm with the 'spm-algo' value in the YAML config file.	9 years ago
maxtors	9d3fd82849	Removed duplicate include statements.	9 years ago
Jason Ish	796dd5223b	tests: no longer necessary to provide successful return code ... 1 pass, 0 is fail.	9 years ago
Victor Julien	d6ba01b1b7	detect: make port whitelisting configurable ... Make the port grouping whitelisting configurable. A whitelisted port ends up in it's own port group. detect: grouping: tcp-whitelist: 80, 443 udp-whitelist: 53, 5060 No portranges are allowed at this point.	9 years ago
Victor Julien	725d6c3739	yaml: convert detect-engine to just detect ... Instead of detect-engine which used a list for no good reason, use a simple map now. detect: profile: medium custom-values: toclient-groups: 3 toserver-groups: 25 sgh-mpm-context: auto inspection-recursion-limit: 3000 # If set to yes, the loading of signatures will be made after the capture # is started. This will limit the downtime in IPS mode. #delayed-detect: yes	9 years ago
Victor Julien	1dd135d512	mpm: always cleanup factory	9 years ago
Victor Julien	caea596ce5	profiling: output post-prefilter matches ... Dump a json record containing all sigs that need to be inspected after prefilter. Part of profiling. Only dump if threshold is met, which is currently set by: --set detect.profiling.inspect-logging-threshold=200 A file called packet_inspected_rules.json is created in the default log dir.	9 years ago
Victor Julien	722e2dbf7c	profiling: initial rulegroup tracking ... Per rule group tracking of checks, use of lists, mpm matches, post filter counts. Logs SGH id so it can be compared with the rule_group.json output. Implemented both in a human readable text format and a JSON format.	9 years ago
