From 7cba34a1e3aef9cb057db2a5f5fab22473aabc48 Mon Sep 17 00:00:00 2001 From: Ivan Nardi <12729895+IvanNardi@users.noreply.github.com> Date: Sat, 4 Dec 2021 13:30:10 +0100 Subject: Improve IPv6 support, enabling IPv6 traffic on (almost) all dissectors. (#1380) There are no valid reasons for a (generic) protocol to ignore IPv6 traffic. Note that: * I have not found the specifications of "CheckPoint High Availability Protocol", so I don't know how/if it supports IPv6 * all LRU caches are still IPv4 only Even if src_id/dst_id stuff is probably useless (see #1279), the right way to update the protocol classification is via `ndpi_set_detected_protocol()` --- src/lib/protocols/teredo.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/lib/protocols/teredo.c') diff --git a/src/lib/protocols/teredo.c b/src/lib/protocols/teredo.c index 3a81b1b4b..830921603 100644 --- a/src/lib/protocols/teredo.c +++ b/src/lib/protocols/teredo.c @@ -36,7 +36,7 @@ void ndpi_search_teredo(struct ndpi_detection_module_struct *ndpi_struct, struct && ((ntohs(packet->udp->source) == 3544) || (ntohs(packet->udp->dest) == 3544)) && (packet->payload_packet_len >= 40 /* IPv6 header */)) { NDPI_LOG_INFO(ndpi_struct,"found teredo\n"); - ndpi_int_change_protocol(ndpi_struct, flow, NDPI_PROTOCOL_TEREDO, NDPI_PROTOCOL_UNKNOWN); + ndpi_set_detected_protocol(ndpi_struct, flow, NDPI_PROTOCOL_TEREDO, NDPI_PROTOCOL_UNKNOWN); } else { NDPI_EXCLUDE_PROTO(ndpi_struct, flow); } @@ -48,6 +48,7 @@ void init_teredo_dissector(struct ndpi_detection_module_struct *ndpi_struct, u_i ndpi_set_bitmask_protocol_detection("TEREDO", ndpi_struct, detection_bitmask, *id, NDPI_PROTOCOL_TEREDO, ndpi_search_teredo, + /* Teredo is inherently IPV4 only */ NDPI_SELECTION_BITMASK_PROTOCOL_UDP_WITH_PAYLOAD, SAVE_DETECTION_BITMASK_AS_UNKNOWN, ADD_TO_DETECTION_BITMASK); -- cgit v1.2.3
