* 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

* 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>
* Add ZUG consensus protocol dissector. (#2458)Toni2024-05-28
| | | Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* 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>

* 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
| | | Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Add support for Mastodon, Bluesky and (FB-)Threads (#2418)Ivan Nardi2024-05-06
|
* 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
* Merge RTP and RTCP logic (#2416)Ivan Nardi2024-05-06
| | | | | | | | | Avoid code duplication between these two protocols. We remove support for RTCP over TCP; it is quite rare to find this kind of traffic and, more important, we have never had support for RTP over TCP: we should try to add both detecion as follow-up. Fix a message log in the LINE code
* TLS: fix Ja4 fingerprint computation (#2419)Ivan Nardi2024-05-05
| | | | | | | | | | | | | | | | | The new values has been checked against the ones reported by Wireshark.

* eDonkey: improve/update classification (#2410)Ivan Nardi2024-05-04
| | | | | | | | | | eDonkey is definitely not as used as >10 years ago, but it seems it is still active. While having a basic TCP support seems easy, identification over UDP doesn't work and it is hard to do it rightly (packets might be only 2 bytes long): remove it.

* Updated JA4 test resultsLuca Deri2024-05-02

* DTLS: add support for Alert message type (similar to TLS) (#2406)Ivan Nardi2024-04-25
|
* Add Adobe Connect support (#2407)0x41CEA552024-04-24
|
* Remove PPStream protocol and add iQIYI (#2403)0x41CEA552024-04-23
| | | | | | P2P video player PPStream was discontinued shortly after the purchase of PPS.tv by Baidu (iQIYI) on 2013 (see https://www.techinasia.com/report-baidu-acquires-video-rival-pps) So we remove the old `NDPI_PROTOCOL_PPSTREAM` logic and add `NDPI_PROTOCOL_IQIYI` id to handle all the iQIYI traffic, which is basically video streaming traffic. A video hosting service, called PPS.tv, is still offered by the same company: for the time being we classified both services with the same protocol id.
* Add BFCP protocol support (#2401)0x41CEA552024-04-23

* STUN: slightly faster sub-classification with DTLS (#2404)Ivan Nardi2024-04-23
|
* Remove obsolete protocols: tuenty, tvuplayer and kontiki (#2398)0x41CEA552024-04-19

* Add KNXnet/IP protocol support (#2397)0x41CEA552024-04-19
| | | | | * Add KNXnet/IP protocol support * Improve KNXnet/IP over TCP detection
* Domain Classification Improvements (#2396)Luca Deri2024-04-18
| | | | | | | | | | | | | | | | | | | * Added size_t ndpi_compress_str(const char * in, size_t len, char * out, size_t bufsize); size_t ndpi_decompress_str(const char * in, size_t len, char * out, size_t bufsize); used to compress short strings such as domain names. This code is based on https://github.com/Ed-von-Schleck/shoco * Major code rewrite for ndpi_hash and ndpi_domain_classify * Improvements to make sure custom categories are loaded and enabled * Fixed string encoding * Extended SalesForce/Cloudflare domains list
* STUN: try to stop extra dissection earlier, if possible (#2390)Ivan Nardi2024-04-13
