Shivani Bhardwaj	6702791a9c	doc: add dcerpc.max-stub-size config param	1 week ago
Jason Ish	2c95f1ff44	dnp3: bound the maximum number of objects per tx Default to 2048, but provide a user configuration value. Ticket: #8181	1 week ago
Jason Ish	3a32bb5743	dnp3: set a bound on the number of points per message 16384 is used as the max, but a configuration parameter has been provided. The reason for setting an upper bound is that bit flags can create a memory amplification as we parse them into individual data structures. Ticket: #8181	1 week ago
Jason Ish	a16f087b93	dnp3: reduce flood threshold to 32 and make configurable Lower the number of unreplied requests from 500 to 32 to consider a flood. At the very least this is an anomaly given the DNP3 spec mentions that DNP3 should only have one outstanding request at a time, with an exception for unsolicited responses, so in practice no more than 2 should be seen. Additionally make this value configurable by introducing the max-tx parameter. Ticket: #8181	1 week ago

Shivani Bhardwaj	30bdaa44e1	doc: add elephant.flow usage section	3 weeks ago
Shivani Bhardwaj	06eafb79d6	detect/flow-pkts: check for both dir The functionality of "both" can already be easily achieved by using both "toclient" and "toserver" in a rule. This just adds the ease of expression in rule. As it is added now, check the direction for the pre-existing users of direction as well.	3 weeks ago
Juliana Fajardini	0ca874b678	userguide: highlight exceptions interactions In corner cases, we assume that a midstream exception policy could be triggered by a prior exception policy in effect. Explain this in the docs. Task #5830	1 month ago

Philippe Antoine	c93e69830a	detect/ssl: properly handle negation in ssl_version keyword Ticket: 3220 DetectSslVersionMatch did not handle properly negation. It could never match on a signatrue with ssl_version: !tls1.3 That is because, if we had such a signature and network traffic with tls1.1, we were looking into DetectSslVersionData field for tls1.1, which was not set, instead of looking at field for tls1.3 which was set with negated flag. Previous DetectSslVersionData was holding redundant information. It did not need to have it for each ssl version, but just globally. Also, it did not need to hold the version as a value in the array, as it was redundant with the index of the array.	1 month ago

Juliana Fajardini	1647081b29	doc: remove remaining references to pruned flows These were removed with `a5587fec2e` but these mentions went under the radar.	2 months ago

Philippe Antoine	d8cb00e795	detect/tcp: make tcp.flags a generic integer with bitflags Ticket: 6724 Allows to use numerical values for example Also fixes some unit tests that were returning 1 after goto error FlagsTestParse05 especially took this path as de->ignored_flags != (TH_SYN\|TH_RST) was false we had de->ignored_flags == 0xff ^ (TH_SYN\|TH_RST) And then, we had a match, instead of what the not-run code was supposing.	3 months ago
Philippe Antoine	1f9236a6d8	detect/ipv4: make fragbits a generic uint16 bitflags keyword Ticket: 6724 Allows to use numerical values	3 months ago
Philippe Antoine	633180c93f	detect/integers: generalize support for bitflags modifier Ticket: 6724 Allows sugar syntax for bitflags keywords. While the expressivity does not increase, because we could already use numerial values with all generic integer modes, this modifier prefix is used with the strings, and follows the syntax that is already used for fragbits and tcp.flags keyword.	3 months ago
Philippe Antoine	4b69a31dc3	detect/integers: count argument for multi-integers Ticket: 7211 Allows to count the number of elements, without matching on individual elements	3 months ago
