Victor Julien	3f04af7c7f	doc: add thresholding by_flow	1 year ago
Victor Julien	f028648750	detect/content: fix wrong value for depth check ... Limits propegation checked for DETECT_DEPTH as a content flag, which appears to have worked by chance. After reshuffling the keyword id's it no longer worked. This patch uses the proper flag DETECT_CONTENT_DEPTH.	1 year ago
Victor Julien	d0f3f2d462	detect: group content inspect keyword id's	1 year ago
Victor Julien	022173d7ab	detect: group types used in traffic variables ... Traffic variables (flowvars, flowbits, xbits, etc) use a smaller int for their type than detection types. As a workaround make sure the values fit in a uint8_t.	1 year ago
Victor Julien	cfd55ead74	threshold: add by_flow support for global thresholds ... Allow rate_filter and thresholds from the global config to specify tracking "by_flow".	1 year ago
Victor Julien	1552f0953a	detect/threshold: implement tracking 'by_flow' ... Add support for 'by_flow' track option. This allows using the various threshold options in the context of a single flow. Example: alert tcp ... stream-event:pkt_broken_ack; \ threshold:type limit, track by_flow, count 1, seconds 3600; The example would limit the number of alerts to once per hour for packets triggering the 'pkt_broken_ack' stream event. Implemented as a special "flowvar" holding the threshold entries. This means no synchronization is required, making this a cheaper option compared to the other trackers. Ticket: #6822.	1 year ago

Jeff Lucovsky	5b97f4040c	detect/base64: Use Rust defined modes everywhere ... Issue: 6487 To avoid ambiguity, a single definition for base 64 decoding modes will be used. The Rust base64 transform contains the definitions for the existing mode types: Strict, RFC2045, RFC4648	1 year ago

Jeff Lucovsky	f042e9034b	detect/transform: Add from_base64 transform ... Issue: 6487 Implement the from_base64 transform: [bytes value] [offset value] [mode strict|rfc4648|rfc2045] The value for bytes and offset may be a byte_ variable or an unsigned integer.	1 year ago
Jeff Lucovsky	1823681709	detect/transform: from_base64 option parsing ... Issue: 6487 Implement from_base64 option parsing in Rust. The Rust module also contains unit tests.	1 year ago

Philippe Antoine	5f35035928	filestore: do not try to store a file set to nostore ... Ticket: 6390 This can happen with keyword filestore:both,flow If one direction does not have a signature group with a filestore, the file is set to nostore on opening, until a signature in the other direction tries to set it to store. Subsequent files will be stored in both directions as flow flags are now set.	1 year ago
