Function Documentation

◆ DetectEngineAppendSig()

Signature* DetectEngineAppendSig	(	DetectEngineCtx *	de_ctx,
		const char *	sigstr
	)

Parse and append a Signature into the Detection Engine Context signature list.

If the signature is bidirectional it should append two signatures (with the addresses switched) into the list. Also handle duplicate signatures. In case of duplicate sigs, use the ones that have the latest revision. We use the sid and the msg to identify duplicate sigs. If 2 sigs have the same sid and gid, they are duplicates.

Parameters

de_ctx	Pointer to the Detection Engine Context.
sigstr	Pointer to a character string containing the signature to be parsed.
sig_file	Pointer to a character string containing the filename from which signature is read
lineno	Line number from where signature is read

Return values

Pointer to the head Signature in the detection engine ctx sig_list on success; NULL on failure.

In DetectEngineAppendSig(), the signatures are prepended and we always return the first one so if the signature is bidirectional, the returned sig will point through "next" ptr to the cloned signatures with the switched addresses
