* Zoom: remove "stun_zoom" LRU cacheNardi Ivan2024-06-17
| | | | | Since 070a0908b we are able to detect P2P calls directly from the packet content, without any correlation among flows
* Update main Readme and remove commented out code (#2471)Ivan Nardi2024-06-17
| | | | Avoid that useless code is copy-and-pasted into new dissector, as in https://github.com/ntop/nDPI/pull/2470#discussion_r1639384434

* 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

* TLS: add support for DTLS (over STUN) over TCP (#2463)Ivan Nardi2024-06-05

* 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

* CiscoVPN: we detect it only over UDP (#2454)Ivan Nardi2024-05-28
| | | The original code handled also TCP/TLS, but it was removed in 6fc29b3ae
* 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
* Remove Vevo support (#2436)Vladimir Gavrilov2024-05-11

* 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..)

But the only way to check if the `HASH_ADD_*` failed, is to perform a new lookup: a bit costly, but we don't use that code in the fast-path.

* Remove "zoom" cache (#2420)Ivan Nardi2024-05-06
| | | | | | | | | This cache was added in b6b4967aa, when there was no real Zoom support. With 63f349319, a proper identification of multimedia stream has been added, making this cache quite useless: any improvements on Zoom classification should be properly done in Zoom dissector. Tested for some months with a few 10Gbits links of residential traffic: the cache pretty much never returned a valid hit.
* Remove workaround for TCP flows with multiple SYNs (#2421)Ivan Nardi2024-05-06
| | | | | Deciding when a session starts and ends is responsability of the applicationi (via its flow manager)i, not of the library. BTW, the removed code is incomplete at beast
* 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
