◆ AlertQueueAppend()

void AlertQueueAppend	(	DetectEngineThreadCtx *	det_ctx,
		const Signature *	s,
		Packet *	p,
		uint64_t	tx_id,
		uint8_t	alert_flags
	)

Append signature to local packet alert queue for later preprocessing.

◆ AlertQueueFree()

void AlertQueueFree ( DetectEngineThreadCtx * det_ctx )

Definition at line 216 of file detect-engine-alert.c.

◆ AlertQueueInit()

void AlertQueueInit ( DetectEngineThreadCtx * det_ctx )

Definition at line 203 of file detect-engine-alert.c.

◆ PacketAlertCheck()

int PacketAlertCheck	(	Packet *	p,
		uint32_t	sid
	)

Check if a certain sid alerted, this is used in the test functions.

Parameters

p	Packet on which we want to check if the signature alerted or not
sid	Signature id of the signature that has to be checked for a match

Return values

match A value > 0 on a match; 0 on no match

◆ PacketAlertFinalize()

void PacketAlertFinalize	(	DetectEngineCtx *	de_ctx,
		DetectEngineThreadCtx *	det_ctx,
		Packet *	p
	)

Check the threshold of the sigs that match, set actions, break on pass action This function iterate the packet alerts array, removing those that didn't match the threshold, and those that match after a signature with the action "pass". The array is sorted by action priority/order.

Parameters

de_ctx	detection engine context
det_ctx	detection engine thread context
p	pointer to the packet
