Eric Leblond	a85dc9b0e2	Add support for replace keyword. ... This patch adds support for the replace keyword. It is used with content to change selected part of the payload. The major point with this patch is that having a replace keyword made necessary to avoid all stream level check because we need to access to the could-be-modified packet payload. One of the main difficulty is to handle complex signature. If there is other content check, we must do the substitution when we're sure all match are valid. The patch adds an attribute to the thread context variable to be able to deal with recursivity of the match function. Replace is only activated in IPS mode and apply only to raw match.	14 years ago
Eric Leblond	0c34a1c5e7	rewrite constants and add flag for replace ... This patch make use of bit shift to rewrite some of the mask constants. It also delete an unused flag value and suppress the associated dead code. The numeric value of the flag is now used by the flag needed for replace code.	14 years ago
Eric Leblond	3f153fb0da	Add 'stream-event' keyword. ... This patch adds an alias to the 'engine-event' keyword. It is now possible to access to the stream events via the 'stream-event' keyword. A simple transformation is done: stream-event:reassembly_segment_before_base_seq is a shortcut for: engine-event:stream.reassembly_segment_before_base_seq	14 years ago
Eric Leblond	e3a6d8955e	Introduce engine-event keyword ... This patch renames the 'decode-event' keyword to 'engine-event' and keep it for backword compatibility of rulesets. All *DecodeEvent* references in the code are replaced by EngineEvent version.	14 years ago
Eric Leblond	03c185a3ad	threshold: add suppress keyword ... This patch adds the suppress keyword to the threshold.config file. The alerts are suppressed but the other elements like flowbits are maintained.	14 years ago

Eric Leblond	9beebf621a	Add support for 'nfq_set_mark' keyword ... This patch introduces 'nfq_set_mark' which is new rules option. If a packet matches a rule using nfq_set_mark in NFQ mode, it is marked with the mark/mask specified in the option during the verdict. It is thus possible to trigger different behaviour on the packet inside Linux/Netfilter.	15 years ago
