* Fix CNP-IP false positives (#2531)Vladimir Gavrilov2024-08-30
|
* Add TRDP protocol support (#2528)Vladimir Gavrilov2024-08-25
| | | The Train Real Time Data Protocol (TRDP) is a UDP/TCP-based communication protocol designed for IP networks in trains, enabling data exchange between devices such as door controls and air conditioning systems. It is standardized by the IEC under IEC 61375-2-3 and is not related to the Remote Desktop Protocol (RDP).

* Add CNP/IP protocol support (#2521)Vladimir Gavrilov2024-08-22
| | | ISO/IEC 14908-4 defines how to tunnel Control Network Protocol (CNP) over IP networks. It encapsulates protocols like EIA-709, EIA-600, and CNP, making it a versatile solution for building automation and control systems.

* RTP/STUN: look for STUN packets after RTP/RTCP classification (#2465)Ivan Nardi2024-06-07
| | | | | | | | | | After a flow has been classified as RTP or RTCP, nDPI might analyse more packets to look for STUN/DTLS packets, i.e. to try to tell if this flow is a "pure" RTP/RTCP flow or if the RTP/RTCP packets are multiplexed with STUN/DTLS. Useful for proper (sub)classification when the beginning of the flows are not captured or if there are lost packets in the the captured traffic. Disabled by default
* Zoom: faster detection of P2P flows (#2467)Ivan Nardi2024-06-07

* STUN: add support for Microsoft Multiplexed TURN channels (#2464)Ivan Nardi2024-06-05

* TLS: add support for DTLS (over STUN) over TCP (#2463)Ivan Nardi2024-06-05
| | | | | TODO: TCP reassembler on top of UDP reassembler See: #2414
* RTP: fix detection over TCP (#2462)Ivan Nardi2024-05-29
| | | | | | RFC4571 is not the only way to wrap RTP messages in TCP streams. For example, when RTP is encapsulated over TURN flows (i.e. via DATA attribute) there is no additional framing. See also 6127e0490
* support rtp/rtcp over tcp (#2422) (#2457)Maatuq2024-05-28
| | | | | Support rtp/rtcp over tcp as per rfc4571. Signed-off-by: mmaatuq <mahmoudmatook.mm@gmail.com>

* Improved Kafka dissector. (#2456)Toni2024-05-27
| | | | | | | | | * detect more Kafka request packet's * requires less flow memory * same detection behavior as before e.g. no asym detection implemented (can be done by dissecting responses, requires more effort) Signed-off-by: Toni Uhlig <matzeton@googlemail.com> Co-authored-by: Nardi Ivan <nardi.ivan@gmail.com>

* IRC: simplify detection (#2423)Ivan Nardi2024-05-11
| | | | | | | | | | | | | | | | IRC has its best times well behind, but there are still some servers using it. We should try to simplify the detection logic, still based on OpenDPI logic. Let's start with some easy changes: * try to detect TLS connection via standard hostname/SNI matching, removing an old heuristic (we have never had any trace matching it); * add some basic server names; * once we detect that the flow is IRC, we don't have to perform anything else; * remove HTTP stuff; real HTTP flows never trigger that data path * use `ndpi_memmem()` when possible
* Viber: add detection of voip calls and avoid false positives (#2434)Ivan Nardi2024-05-11
|
* Line: use common helper to detect RTP/RTCP packets (#2429)Ivan Nardi2024-05-10
| | | | Add an explicit upper limit on the number of packets processed before giving up.
* Raknet/RTP: avoid Raknet false positives and harden RTP heuristic (#2427)Ivan Nardi2024-05-09
| | | | | | | | | There is some overlap between RTP and Raknet detection: give precedence to RTP logic. Consequences: * Raknet might require a little bit more packets for some flows (not a big issue) * some very small (1-2 pkts) Raknet flows are not classified (not sure what do do about that..)
* Protobuf: fix false positives (#2428)Ivan Nardi2024-05-09

* Add extra entropy checks and more precise(?) analysis. (#2383)Toni2024-05-09

* Renamed radius source file to avoid name clashes on WindowsLuca Deri2024-05-07
|
* TLS: avoid setting `NDPI_TLS_SELFSIGNED_CERTIFICATE` for webrtc traffic (#2417)Ivan Nardi2024-05-06
| | | | | | See RFC8122: it is quite likely that STUN/DTLS/SRTP flows use self-signed certificates Follow-up of b287d6ec8
