Victor Julien	edeeb7ed44	Store TX id with alerts ... When generating an alert and storing it in the packet, store the tx_id as well. This way the output modules can log the tx_id and access the proper tx for logging. Issue #904.	12 years ago

Eric Leblond	efaa9a7302	action handling: define and use macros ... The action field in Packet structure should not be accessed directly as the tunneled packet needs to update the root packet and not the initial packet. This patch is fixing issue #819 where suricata was not able to drop fragmented packets in AF_PACKET IPS mode. It also fixes drop capability for tunneled packets.	12 years ago

Eric Leblond	e176be6fcc	Use unlikely for error treatment. ... When handling error case on SCMallog, SCCalloc or SCStrdup we are in an unlikely case. This patch adds the unlikely() expression to indicate this to gcc. This patch has been obtained via coccinelle. The transformation is the following: @istested@ identifier x; statement S1; identifier func =~ "(SCMalloc|SCStrdup|SCCalloc)"; @@ x = func(...) ... when != x - if (x == NULL) S1 + if (unlikely(x == NULL)) S1	13 years ago

Victor Julien	8f71333e12	file: implement filesize keyword. #489.	13 years ago
Victor Julien	4cde2355bd	Simplify flow resetting on de_ctx update. Detect ctx id starts at 1. So in a flow 0 means uninitialized (thus set) and if we detect flow is not equal to detect id, we reset the sgh storage and de_state.	13 years ago
Anoop Saldanha	ecad4a24fa	live rule support added ... To reload ruleset during engine runtime, send the USR2 signal to the engine, and the ruleset would be reloaded from the same yaml file supplied at engine startup	13 years ago

Victor Julien	b74c73309b	file handling: improve filestore keyword handling ... In stateful detection only inspect the file portion of the rule after all other conditions matched.
