* STUN: improve demultiplexing of DTLS packets (#2153)Ivan Nardi2023-11-27
| | | | | | Keep demultiplexing STUN/RTP/RTCP packets after DTLS ones. We might end up processing the session a little longer, because we will process the STUN/RTP/RTCP packets after the DTLS handshake.

* fuzz: improve coverage and remove dead code (#2135)Ivan Nardi2023-11-07
| | | | | | | | | | We are not able to remove custom rules: remove the empty stubs (which originate from the original OpenDPI code). `ndpi_guess_protocol_id()` is only called on the first packet of the flow, so the bitmask `flow->excluded_protocol_bitmask` is always empty, since we didn't call any dissectors yet. Move another hash function to the dedicated source file.
* Added malicious sites from the polish cert. (#2121)Toni2023-11-02
| | | | | * added handling of parsing errors Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* 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.

* Add support for (un-encrypted) HTTP/2 (#2087)Ivan Nardi2023-09-18
| | | | Plaintext HTTP/2 is quite rare on the general "internet" but it is used in some private networks (example: 5G core network)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | probabilistic approach for handling Internet domain names. For switching back to Aho-Corasick it is necessary to edit ndpi-typedefs.h and uncomment the line // #define USE_LEGACY_AHO_CORASICK [1] With Aho-Corasick $ ./example/ndpiReader -G ./lists/ -i tests/pcap/ookla.pcap | grep Memory nDPI Memory statistics: nDPI Memory (once): 37.34 KB Flow Memory (per flow): 960 B Actual Memory: 33.09 MB Peak Memory: 33.09 MB [2] With the new algorithm $ ./example/ndpiReader -G ./lists/ -i tests/pcap/ookla.pcap | grep Memory nDPI Memory statistics: nDPI Memory (once): 37.31 KB Flow Memory (per flow): 960 B Actual Memory: 7.42 MB Peak Memory: 7.42 MB In essence from ~33 MB to ~7 MB This new algorithm will enable larger lists to be loaded (e.g. top 1M domans https://s3-us-west-1.amazonaws.com/umbrella-static/index.html) In ./lists there are file names that are named as <category>_<string>.list With -G ndpiReader can load all of them at startup

* DNS: extract geolocation information, if available (#2065)Ivan Nardi2023-07-31
| | | | | | | The option NSID (RFC5001) is used by Google DNS to report the airport code of the metro where the DNS query is handled. This option is quite rare, but the added overhead in DNS code is pretty much zero for "normal" DNS traffic
* ProtonVPN: split the ip list (#2060)Ivan Nardi2023-07-27
| | | | | | | | | | | Use two separate lists: * one for the ingress nodes, which triggers a ProtonVPN classification * one for the egress nodes, which triggers the `NDPI_ANONYMOUS_SUBSCRIBER` risk Add a command line option (to `ndpiReader`) to easily test IP/port matching. Add another example of custom rule.
* Add an heuristic to detect fully encrypted flows (#2058)Ivan Nardi2023-07-26
| | | | | | | | A fully encrypted session is a flow where every bytes of the payload is encrypted in an attempt to “look like nothing”. The heuristic needs only the very first packet of the flow. See: https://www.usenix.org/system/files/sec23fall-prepub-234-wu-mingshi.pdf A basic, but generic, inplementation of the popcpunt alg has been added
