Philippe Antoine	3a092f3027	detect: allow rule which need both directions to match ... Ticket: 5665 This is done with `alert ip any any => any any` The => operator means that we will need both directions	8 months ago
Philippe Antoine	4ec90bd227	detect: absent keyword to test absence of sticky buffer ... Ticket: 2224 It takes an argument to match only if the buffer is absent, or it can still match if the buffer is present, but we test the absence of some content. For multi buffers, absent matches if there are 0 buffers. For file keywords, absent matches if there is no file.	12 months ago
Philippe Antoine	0d267e29a5	files: remove the need for state in callbacks ... As files now belong to transactions	1 year ago
Philippe Antoine	20423fdd38	style: remove some useless return ... and remove empty line before end of function	1 year ago
Victor Julien	b1fa975503	detect/content-inspect: remove const casting	2 years ago
Victor Julien	7f42506760	detect: reimplement discontinue matching logic ... Previously various steps in the content inspection logic would use a variable in the DetectEngineThreadCtx to flag that matching should be discontinued. This patch reimplements this logic by using a new return code instead. Split content inspection into public and private version, so that common initialization can be done in a single place. Update the callsites.	2 years ago
Victor Julien	68a2fcaad3	mpm: thread ctx cleanups ... Remove unused thread ctx' from AC variants Use single thread store in detection. Minor cleanups.	2 years ago
Victor Julien	c5d83d081e	detect/file: use util to turn keyword to nocase ... This changes the way the pattern is stored by making it lowercase.	2 years ago
Jeff Lucovsky	f735e309e2	detect/file_data: Consolidate file handling ... Issue: 4145 Consolidate file handling for all protocols that use file objects for file_data. Make sure http_server_body / http.response_body for HTTP1 continue to inspect the actual body. For HTTP2, http.response_body acts as an internal alias for `file_data`.	2 years ago
Victor Julien	2cac440f7d	detect/filemagic: fix thread ctx registration; reloads ... Make sure thread ctx registration happens and id remains correct in case of reloads. To do so, move id var into the detect ctx.	2 years ago
Victor Julien	1f22b51848	detect/filemagic: switch to file.magic implementation ... Replace implementation of the legacy `filemagic` keyword by the implementation for the `file.magic` variant. This leads to better performance and hooks the rules into the detection engine better. Remove unittests that depended on the old logic. Ticket: #6194.	2 years ago
Philippe Antoine	e75956717d	detect/files: centralize definition of protocols ... Protocols supporting files are only defined in one place, which gets used by all keywords, which can handle some exceptions (like HTTP2 not having file names)	2 years ago
Victor Julien	da89164ba1	detect: spelling: DetectBufferMpmRegistry	3 years ago
Victor Julien	5890a8a8ab	detect: register multi-buffer keywords ... Register the keywords that use multi buffer support as such, so that rule parsing can set them up with multi-instance support. Ticket: #5784.	3 years ago

Alice Akaki	8614bff017	detect-filemagic: convert unittests to FAIL/PASS APIs ... Task: #4034	3 years ago
Victor Julien	41265a859e	detect/files: optimize file.data by skipping non-file txs ... As well as 'file' txs not in our direction. Implement the same logic for file.name and file.magic prefilter engines.	3 years ago
Victor Julien	3263202094	detect/tx: add AppLayerTxData to PrefilterTx ... In preparation of some file inspection optimizations, for which we need the tx data. Update all users.	3 years ago
Victor Julien	79499e4769	app-layer: move files into transactions ... Update APIs to store files in transactions instead of the per flow state. Goal is to avoid the overhead of matching up files and transactions in cases where there are many of both. Update all protocol implementations to support this. Update file logging logic to account for having files in transactions. Instead of it acting separately on file containers, it is now tied into the transaction logging. Update the filestore keyword to consider a match if filestore output not enabled.	3 years ago

Victor Julien	3dc50322db	detect: fix multi inspect buffer issue; clean up ... Fix multi inspect buffer API causing cleanup logic in the single inspect buffer paths. This could lead to a buffer overrun in the "to clear" logic. Multi buffers now use InspectionBufferSetupMulti instead of InspectionBuffer. This is enforced by a check in debug validation. Simplify the multi inspect buffer setup code and update the callers.	4 years ago
Philippe Antoine	707f027231	protos: renaming ALPROTO_HTTP* constants ... Having now ALPROTO_HTTP1, ALPROTO_HTTP2 and ALPROTO_HTTP Run with 3 sed commands git grep ALPROTO_HTTP | cut -d: -f1 | uniq | xargs sed -i -e 's/ALPROTO_HTTP/ALPROTO_HTTP1/g' git grep ALPROTO_HTTP12 | cut -d: -f1 | uniq | xargs sed -i -e 's/ALPROTO_HTTP12/ALPROTO_HTTP2/g' git grep ALPROTO_HTTP1_ANY | cut -d: -f1 | uniq | xargs sed -i -e 's/ALPROTO_HTTP1_ANY/ALPROTO_HTTP/g' and then running clang-format	5 years ago
Victor Julien	13cebb1857	detect: fix heap overflow issue with buffer setup ... In some cases, the InspectionBufferGet function would be followed by a failure to set the buffer up, for example due to a HTTP body limit not yet being reached. Yet each call to InspectionBufferGet would lead to the matching list_id to be added to the DetectEngineThreadCtx::inspect.to_clear_queue. This array is sized to add each list only once, but in this case the same id could be added multiple times, potentially overflowing the array.	5 years ago
Angelo Mirabella	c72069c3b2	detect/magic: fix crash on rule reloading ... This changseset fixes a bug causing a segmentation fault. When rules are reloaded and a rule using libmagic matches, suricata crashes due to an improper reinitialization of the thread contexts. Bug: #3726	5 years ago

Victor Julien	6ab323d323	detect: hide RegisterTests behind ifdef UNITTESTS ... Update all callers to more aggressively use UNITTESTS guards as well.	5 years ago

Jeff Lucovsky	d3a65fe156	detect: Provide `de_ctx` to free functions ... This commit makes sure that the `DetectEngineCtx *` is available to each detector's "free" function.	6 years ago
Victor Julien	a4a4d17ad0	app-layer/files: optimize GetFiles calls ... Remove FlowGetProtoMapping calls from the GetFiles wrapper and get the alstate from the flow directly.	6 years ago
Victor Julien	4dff903b35	detect: introduce pkt mpm engines ... Instead of the hardcode L4 matching in MPM that was recently introduced, add an API similar to the AppLayer MPM and inspect engines. Share part of the registration code with the AppLayer. Implement for the tcp.hdr and udp.hdr keywords.	6 years ago
Victor Julien	14896365ef	detect: remove Threadvars argument from API calls ... Remove it as it's (almost) never used. If it is really needed it can be accessed through DetectEngineThreadCtx::tv as well.	6 years ago
Victor Julien	32fb7d773a	detect/content-inspect: turn void arg into Packet ... Replace the 'void *data' argument by a 'Packet *p' as this was the only user left of the data pointer.	7 years ago
