* Swap from Aho-Corasick to an experimental/home-grown algorithm that uses a ↵Luca Deri2023-08-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* fuzz: extend coverage (#2073)Ivan Nardi2023-08-20

* Mullvad VPN service added (based on entry node IP addresses) (#2062)snicket21002023-08-02

* Add Service Location Protocol dissector. (#2036)Toni2023-08-01

* 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

* added feature to extract filename from http attachment (#2037)Chiara Maggi2023-07-11
| | | | | | | | | | | | | | | | | | | * added feature to extract filename from http attachment * fixed some issues * added check for filename format * added check for filename format * remove an unnecessary print * changed the size from 952 to 960 * modified some test result files * small changes string size * comment removed and mallocs checked
* fuzz: extend fuzzing coverage (#2040)Ivan Nardi2023-07-11
| | | | | | | | | Some notes: * libinjection: according to https://github.com/libinjection/libinjection/issues/44, it seems NULL characters are valid in the input string; * RTP: `rtp_get_stream_type()` is called only for RTP packets; if you want to tell RTP from RTCP you should use `is_rtp_or_rtcp()`; * TLS: unnecessary check; we already make the same check just above, at the beginning of the `while` loop
* Fixed heap-overflow if compiled with `--enable-tls-sigs`. (#2038)Toni2023-07-07

* STUN: avoid FacebookVoip false positives (#2029)Ivan Nardi2023-07-03
| | | | Attribute 0xC057 is defined in the Google public implementation of webrtc (which is used by Google products but also by other applications)

|
* 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.
* STUN: add dissection of DTLS handshake (#2018)Ivan Nardi2023-06-26
|
* Simplify the report of streaming multimedia info (#2026)Ivan Nardi2023-06-26
| | | | | The two fields `flow->flow_type` and `flow->protos.rtp.stream_type` are pretty much identical: rename the former in `flow->flow_multimedia_type` and remove the latter.
* 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)

* oss-fuzz: sync build script with upstreamNardi Ivan2023-06-12
| | | | | | | | | | | | File copied from https://github.com/google/oss-fuzz/blob/master/projects/ndpi/build.sh The general idea is to keep the build script in our repository and use it from oss-fuzz builder: updating it from our side is easier and faster then passing via an oss-fuzz PR. The original idea is from @utoni in 3068306b60. Once this change has been merged, we can update the code in oss-fuzz.
