* fuzz: some improvements and add two new fuzzers (#1881)Ivan Nardi2023-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` define from `fuzz/Makefile.am`; it is already included by the main configure script (when fuzzing). Add a knob to force disabling of AESNI optimizations: this way we can fuzz also no-aesni crypto code. Move CRC32 algorithm into the library. Add some fake traces to extend fuzzing coverage. Note that these traces are hand-made (via scapy/curl) and must not be used as "proof" that the dissectors are really able to identify this kind of traffic. Some small updates to some dissectors: CSGO: remove a wrong rule (never triggered, BTW). Any UDP packet starting with "VS01" will be classified as STEAM (see steam.c around line 111). Googling it, it seems right so. XBOX: XBOX only analyses UDP flows while HTTP only TCP ones; therefore that condition is false. RTP, STUN: removed useless "break"s Zattoo: `flow->zattoo_stage` is never set to any values greater or equal to 5, so these checks are never true. PPStream: `flow->l4.udp.ppstream_stage` is never read. Delete it. TeamSpeak: we check for `flow->packet_counter == 3` just above, so the following check `flow->packet_counter >= 3` is always false.

* fuzz: add a new fuzzer to test serialization/deserialization code (#1876)Ivan Nardi2023-01-27
| | | | | | | | | | Autodetecting the needed buffer size is quite complex (especially with float/double values) so it is mandatory to properly check for `ndpi_snprintf` truncation. These issues have been undetected so far probably because the default buffer is big enough for all common cases. Add an example of usage of `ndpi_deserialize_clone_all()` (taken from `ntopng`)

* Some small changes (#1869)Ivan Nardi2023-01-25
| | | | | | | | All dissector callbacks should not be exported by the library; make static some other local functions. The callback logic in `ndpiReader` has never been used. With internal libgcrypt, `gcry_control()` should always return no errors. We can check `categories` length at compilation time.

| | | | Improved DNS dissection
* fuzz: add fuzzer testing nDPI (initial) configurations (#1830)Ivan Nardi2022-12-23
| | | | | | | | | | | | | | | | | The goal of this fuzzer is to test init and deinit of the library, with different configurations. In details: * random memory allocation failures, even during init phase * random `ndpi_init_prefs` parameter of `ndpi_init_detection_module()` * random LRU caches sizes * random bitmask of enabled protocols * random parameters of `ndpi_set_detection_preferences()` * random initialization of opportunistic TLS * random load/don't load of configuration files This new fuzzer is a C++ file, because it uses `FuzzedDataProvider` class (see https://github.com/google/fuzzing/blob/master/docs/split-inputs.md). Note that the (existing) fuzzers need to be linked with C++ compiler anyway, so this new fuzzer doesn't add any new requirements.
* Remove some old protocols (#1832)Ivan Nardi2022-12-23
| | | | | | | | | | | | | | | | | | | | | These protocols: * have been addeded in the OpenDPI era * have never been updated since then * we don't have any pcap examples [*] If (and it is a big if...) some of these protocols are still somehow used and if someone is still interested in them, we can probably re-add them starting from scratch (because the current detection rules are probably outdated) Protocols removed: DIRECT_DOWNLOAD_LINK, APPLEJUICE, DIRECTCONNECT, OPENFT, FASTTRACK, SHOUTCAST, THUNDER, AYIYA, STEALTHNET, FIESTA, FLORENSIA, AIMINI, SOPCAST PPSTREAM dissector works (...) only on UDP. [*]: with do have an AIMINI test pcap but it was some trivial http traffic detected only by hostname matching, on domains no more available...

* Add protocol disabling feature (#1808)Ivan Nardi2022-12-18
| | | | | | | | | | | | | | | | | | | | | | The application may enable only some protocols. Disabling a protocol means: *) don't register/use the protocol dissector code (if any) *) disable classification by-port for such a protocol *) disable string matchings for domains/certificates involving this protocol *) disable subprotocol registration (if any) This feature can be tested with `ndpiReader -B list_of_protocols_to_disable`. Custom protocols are always enabled. Technically speaking, this commit doesn't introduce any API/ABI incompatibility. However, calling `ndpi_set_protocol_detection_bitmask2()` is now mandatory, just after having called `ndpi_init_detection_module()`. Most of the diffs (and all the diffs in `/src/lib/protocols/`) are due to the removing of some function parameters. Fix the low level macro `NDPI_LOG`. This issue hasn't been detected sooner simply because almost all the code uses only the helpers `NDPI_LOG_*`

* TLS: explicit ignore client certificate (#1776)Ivan Nardi2022-10-18
| | | | | | | | | | | | | TLS classification usually stops after processing *server* certificates (if any). That means, that *client* certificate, if present, is usually ignored. However in some corner cases (i.e. unidirectional traffic) we might end up processing client certificate and exposing its metadata: the issue is that the application will think that this metadata are about the server and not about the client. So, for the time being, always ignore client certificate processing. As a future work, we might find an efficient way to process and export both certificates.

* TLS/DTLS: we process certificate for UDP flows, tooNardi Ivan2022-09-30
| | | | | | Note that current code access `certificate_processed` state even before setting the protocol classification, so this piece of information can't be saved in `flow->protos` union.
* Remove unused codeNardi Ivan2022-09-28
| | | | | | | | | LRU callbacks have been added in 460ff3c7a, but they have never been used and they have never been extended to the other LRU caches. `ndpi_search_tcp_or_udp()` basically returns the classification by port/ip of the flow; calling it from the dissector is useless. The same for TOR detection: ips are checked in the generic code
* Sizes of LRU caches are now configurableNardi Ivan2022-09-23
| | | | | | | | 0 as size value disable the cache. The diffs in unit tests are due to the fact that some lookups are performed before the first insert: before this change these lookups weren't counted because the cache was not yet initialized, now they are.
