From 3a087e951d96f509c75344ad6791591e10e4f1cd Mon Sep 17 00:00:00 2001 From: Ivan Nardi <12729895+IvanNardi@users.noreply.github.com> Date: Tue, 11 Jan 2022 15:23:39 +0100 Subject: Add a "confidence" field about the reliability of the classification. (#1395) As a general rule, the higher the confidence value, the higher the "reliability/precision" of the classification. In other words, this new field provides an hint about "how" the flow classification has been obtained. For example, the application may want to ignore classification "by-port" (they are not real DPI classifications, after all) or give a second glance at flows classified via LRU caches (because of false positives). Setting only one value for the confidence field is a bit tricky: more work is probably needed in the next future to tweak/fix/improve the logic. --- src/lib/protocols/fix.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/lib/protocols/fix.c') diff --git a/src/lib/protocols/fix.c b/src/lib/protocols/fix.c index f2d6cad7e..dcfce6065 100644 --- a/src/lib/protocols/fix.c +++ b/src/lib/protocols/fix.c @@ -43,7 +43,7 @@ void ndpi_search_fix(struct ndpi_detection_module_struct *ndpi_struct, struct nd packet->payload[5] == 0x2e) { NDPI_LOG_INFO(ndpi_struct, "found FIX\n"); - ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_FIX, NDPI_PROTOCOL_UNKNOWN); + ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_FIX, NDPI_PROTOCOL_UNKNOWN, NDPI_CONFIDENCE_DPI); return; } // 0. 9= @@ -53,7 +53,7 @@ void ndpi_search_fix(struct ndpi_detection_module_struct *ndpi_struct, struct nd packet->payload[5] == 0x3d) { NDPI_LOG_INFO(ndpi_struct, "found FIX\n"); - ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_FIX, NDPI_PROTOCOL_UNKNOWN); + ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_FIX, NDPI_PROTOCOL_UNKNOWN, NDPI_CONFIDENCE_DPI); return; } } -- cgit v1.2.3
