◆ DetectEngineAppInspectionEngineSignatureFree()

void DetectEngineAppInspectionEngineSignatureFree	(	DetectEngineCtx *	de_ctx,

free app inspect engines for a signature

For lists that are registered multiple times, like http_header and http_cookie, making the engines owner of the lists is complicated. Multiple engines in a sig may be pointing to the same list. To address this the 'free' code needs to be extra careful about not double freeing, so it takes an approach to first fill an array of the to-free pointers before freeing them.

	)

Check content byte array compatibility with transforms.

The "content" array is presented to the transforms so that each transform may validate that it's compatible with the transform.

When a transform indicates the byte array is incompatible, none of the subsequent transforms, if any, are invoked. This means the first validation failure terminates the loop.

Parameters

de_ctx	Detection engine context.
sm_list	The SM list id.
content	The byte array being validated
namestr	returns the name of the transform that is incompatible with content.

Return values

true	(false) If any of the transforms indicate the byte array is (is not) compatible.

◆ DetectEngineThreadCtxInit()

TmEcode DetectEngineThreadCtxInit	(	ThreadVars *	tv,
		void *	initdata,

initialize thread specific detection engine context

Note: there is a special case when using delayed detect. In this case the function is called twice per thread. The first time the rules are not yet loaded. de_ctx->delayed_detect_initialized will be 0. The 2nd time they will be loaded. de_ctx->delayed_detect_initialized will be 1. This is needed to do the per thread counter registration before the packet runtime starts. In delayed detect mode, the first call will return a NULL ptr through the data ptr.

Parameters

tv	ThreadVars for this thread
initdata	pointer to de_ctx
data[out]	pointer to store our thread detection ctx

Return values

TM_ECODE_OK	if all went well
TM_ECODE_FAILED	on serious errors
