void | AlertQueueFree (DetectEngineThreadCtx *det_ctx) |
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. More... | |
void | PacketAlertFinalize (DetectEngineCtx *, DetectEngineThreadCtx *, Packet *) |
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. More... | |
int | PacketAlertCheck (Packet *, uint32_t) |
Check if a certain sid alerted, this is used in the test functions. More... | |
