* When triggering risk "Known Proto on Non Std Port", nDPi now reports the ↵Luca Deri2024-11-22
| | | | port that was supposed to be used as default
* FPC: add DPI information (#2514)Ivan Nardi2024-07-23
| | | | If the flow is classified (via DPI) after the first packet, we should use this information as FPC
* FPC: small improvements (#2512)Ivan Nardi2024-07-22
| | | | Add printing of fpc_dns statistics and add a general cconfiguration option. Rework the code to be more generic and ready to handle other logics.
* Add infrastructure for explicit support of Fist Packet Classification (#2488)Ivan Nardi2024-07-03
| | | | | Let's start with some basic helpers and with FPC based on flow addresses. See: #2322
* 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
* Add extra entropy checks and more precise(?) analysis. (#2383)Toni2024-05-09

* 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.
* STUN: fix boundary checks on attribute list parsing (#2387)Ivan Nardi2024-04-12
| | | | | Restore all unit tests. Add some configuration knobs. Fix the endianess.
* Implemented STUN peer_address, relayed_address, response_origin, ↵Luca Deri2024-04-12
| | | | | | | other_address parsing Added code to ignore invalid STUN realm Extended JSON output with STUN information
* STUN:Luca Deri2024-04-12
| | | | | - Fixed issue with XOR-MAPPED-ADDRESS decoding - Implemented MAPPED_ADDRESS (IPv4 only)
* STUN: improve extraction of Mapped-Address metadata (#2370)Ivan Nardi2024-04-08
| | | | | | | | | | | | | Enable parsing of Mapped-Address attribute for all STUN flows: that means that STUN classification might require more packets. Add a configuration knob to enable/disable this feature. Note that we can have (any) STUN metadata also for flows *not* classified as STUN (because of DTLS). Add support for ipv6. Restore the correct extra dissection logic for Telegram flows.
* Added support for STUN Mapped IP addressLuca Deri2024-04-03

* LRU cache: move to 64 bits long keys (#2346)Ivan Nardi2024-03-15
| | | | | | Tradeoff between key comparison efficiency (i.e. no `memcmp`) and key length. At least in the ipv4 cases, we have no more different entries with the same key.
* STUN: fix category when sub-classification is set in "extra-dissection" data ↵Ivan Nardi2024-02-24

* ndpiReader: add breed stats on output used for CI (#2236)Ivan Nardi2024-01-05
|
* ndpiReader: fix `guessed_flow_protocols` statistic (#2203)Ivan Nardi2023-12-12
| | | Increment the counter only if the flow has been guessed
* STUN: major code rework (#2116)Ivan Nardi2023-10-30
| | | | | | | | | | | | Try to have a faster classification, on first packet; use standard extra dissection data path for sub-classification, metadata extraction and monitoring. STUN caches: * use the proper confidence value * lookup into the caches only once per flow, after having found a proper STUN classification Add identification of Telegram VoIP calls.
* IPv6: add support for IPv6 risk exceptions (#2122)Ivan Nardi2023-10-29
|
* IPv6: add support for IPv6 risk tree (#2118)Ivan Nardi2023-10-27
| | | Fix the script to download crawler addressess
* Jabber: remove support for UDP (#2115)Ivan Nardi2023-10-26
| | | | | | Jabber/XMPP is only over TCP (even the name `ndpi_search_jabber_tcp` suggests that...). Bug introduced in 5266c726f
* ipv6: add support for ipv6 addresses lists (#2113)Ivan Nardi2023-10-26

* Hangout: detect Hangout/Duo/GoogleMeet/... in the STUN code (#2025)Ivan Nardi2023-06-27
| | | | | | Regardless of the name, the removed trace doesn't contain meaningful Hangout traffic. Remove last piece of sub-classifiction based only on ip addresses.
* RTP: rework code (#2021)Ivan Nardi2023-06-23
| | | | | | | Try avoiding false positives: look for 3 RTP packets before classifing the flow as such. Add a generic function `is_rtp_or_rtcp()` to identify RTP/RTCP packets also in other dissectors (see 3608ab01b commit message for an example)

* Fix classification-by-ip in `ndpi_detection_giveup` (#1981)Ivan Nardi2023-05-17
| | | | | | | | | | | | | | Return the "classification-by-ip" as protocol results only if no other results are available. In particular, never return something like "protocol_by_port/protocol_by_ip" (i.e. `NTP/Apple`, BitTorrent/GoogleCloud`, `Zoom/AWS`) because this kind of classification is quite confusing, if not plainly wrong. Notes: * the information about "classification-by-ip" is always available, so no information is lost with this change; * in the unit tests, the previous classifications with confidence `NDPI_CONFIDENCE_DPI_PARTIAL` were wrong, as noted in #1957
* All protocols should be excluded sooner or later (#1969)Ivan Nardi2023-05-10
| | | | | For a lot of protocols, reduce the number of packets after which the protocols dissector gives up. The values are quite arbitary, tring to not impact on classification

* Test multiple `ndpiReader` configurations (#1931)Ivan Nardi2023-04-06
Extend internal unit tests to handle multiple configurations. As some examples, add tests about: * disabling some protocols * disabling Ookla aggressiveness Every configurations data is stored in a dedicated directory under `tests\cfgs`
