From 5cf3fef8f7edc14d1f62750782901b8eec997b2a Mon Sep 17 00:00:00 2001 From: Ivan Nardi <12729895+IvanNardi@users.noreply.github.com> Date: Wed, 29 Sep 2021 13:11:32 +0200 Subject: Remove `detected_protocol_stack` field from `ndpi_packet_struct` (#1317) This field is an exact copy of `ndpi_flow_struct->detected_protocol_stack[2]`: * at the very beginning of packet dissection, the value saved in `flow->detected_protocol_stack` is copied in `packet->detected_protocol_stack` (via `ndpi_detection_process_packet()` -> `ndpi_init_packet_header()`) * every time we update `flow->detected_protocol_stack` we update `packet->detected_protocol_stack` too (via `ndpi_int_change_protocol()` -> `ndpi_int_change_packet_protocol()`) These two fields are always in sync: keeping the same value in two different places is useless. --- src/lib/protocols/gtp.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/lib/protocols/gtp.c') diff --git a/src/lib/protocols/gtp.c b/src/lib/protocols/gtp.c index 98d741384..2c8316ac6 100644 --- a/src/lib/protocols/gtp.c +++ b/src/lib/protocols/gtp.c @@ -115,12 +115,10 @@ static void ndpi_check_gtp(struct ndpi_detection_module_struct *ndpi_struct, str void ndpi_search_gtp(struct ndpi_detection_module_struct *ndpi_struct, struct ndpi_flow_struct *flow) { - struct ndpi_packet_struct *packet = &flow->packet; - NDPI_LOG_DBG(ndpi_struct, "search gtp\n"); /* skip marked packets */ - if(packet->detected_protocol_stack[0] != NDPI_PROTOCOL_GTP) + if(flow->detected_protocol_stack[0] != NDPI_PROTOCOL_GTP) ndpi_check_gtp(ndpi_struct, flow); } -- cgit v1.2.3
