Victor Julien	22f3205664	var-names: expose outside of detect engine ... Until now variable names, such as flowbit names, were local to a detect engine. This made sense as they were only ever used in that context. For the purpose of logging these names, this needs a different approach. The loggers live outside of the detect engine. Also, in the case of reloads and multi-tenancy, there are even multiple detect engines, so it would be even more tricky to access them from the outside. This patch brings a new approach. A any time, there is a single active hash table mapping the variable names and their id's. For multiple tenants the table is shared between tenants. The table is set up in a 'staging' area, where locking makes sure that multiple loading threads don't mess things up. Then when the preparing of a detection engine is ready, but before the detect threads are made aware of the new detect engine, the active varname hash is swapped with the staging instance. For this to work, all the mappings from the 'current' or active mapping are added to the staging table. After the threads have reloaded and the new detection engine is active, the old table can be freed. For multi tenancy things are similar. The staging area is used for setting up until the new detection engines / tenants are applied to the system. This patch also changes the variable 'id'/'idx' field to uint32_t. Due to data structure padding and alignment, this should have no practical drawback while allowing for a lot more vars.	9 years ago

Victor Julien	408948815f	detect: simplify flow locking ... To simplify locking, move all locking out of the individual detect code. Instead at the start of detection lock the flow, and at the end of detection unlock it. The lua code can be called without a lock still (from the output code paths), so still pass around a lock hint to take care of this.	10 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
