* 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`
* Add a new flow risk about literal IP addresses used as SNI (#1892)Ivan Nardi2023-03-02
| | | | | | | | | | RFC 6066 3: "Literal IPv4 and IPv6 addresses are not permitted in "HostName"." Don't set this risk if we have a valid sub-classification (example: via certificate) Since a similar risk already exists for HTTP hostnames, reuse it, with a more generic name.

* Fix classification "by-port" (#1851)Ivan Nardi2023-01-17
| | | | | | | | | | | Classification "by-port" should be the last possible effort, *after* having test all the LRU caches. Remove some dead code from `ndpi_detection_giveup()`: `flow->guessed_protocol_id` is never set to any od those voip protocols and at that point in this function we never have both a master *and* a application protocols. Coverage reports (both from unit tests and from fuzzing) confirms that was dead code.
* Improved DGA detectionLuca Deri2023-01-12

* 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interested in them, we can probably re-add them starting from scratch (because the current detection rules are probably outdated) Protocols removed: DIRECT_DOWNLOAD_LINK, APPLEJUICE, DIRECTCONNECT, OPENFT, FASTTRACK, SHOUTCAST, THUNDER, AYIYA, STEALTHNET, FIESTA, FLORENSIA, AIMINI,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...

* Make LRU caches ipv6 aware (#1810)Ivan Nardi2022-12-03
| | | | | | | | | | | | | Simplest solution, keeping the existing cache data structure TLS certificate cache is used for DTLS traffic, too. Note that Ookla cache already works with ipv6 flows. TODO: * make the key/hashing more robust (extending the key size?) * update bittorrent cache too. That task is quite difficult because ntopng uses a public function (`ndpi_guess_undetected_protocol()`) intrinsically ipv4 only...
* TLS: improve handling of ALPN(s) (#1784)Ivan Nardi2022-10-25
| | | | | | | | Tell "Advertised" ALPN list from "Negotiated" ALPN; the former is extracted from the CH, the latter from the SH. Add some entries to the known ALPN list. Fix printing of "TLS Supported Versions" field.

* LINE_CALL: add detection of LINE voip calls (#1761)Ivan Nardi2022-10-06
| | | | | | | | These flows are classifed as `LINE_CALL`; another option was `RTP/LINE_CALL`. No sure about the best solution... Extend LINE domains list. Remove RTP dead code.
* DNS: change category of DNS flowsNardi Ivan2022-09-25
| | | | | | DNS flows should have `NDPI_PROTOCOL_CATEGORY_NETWORK` as category, regardless of the subprotocol (if any). Follow-up of 83de3e47
* 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.

* Remove classification "by-ip" from protocol stack (#1743)Ivan Nardi2022-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically: * "classification by-ip" (i.e. `flow->guessed_protocol_id_by_ip` is NEVER returned in the protocol stack (i.e. `flow->detected_protocol_stack[]`); * if the application is interested into such information, it can access `ndpi_protocol->protocol_by_ip` itself. There are mainly 4 points in the code that set the "classification by-ip" in the protocol stack: the generic `ndpi_set_detected_protocol()`/ `ndpi_detection_giveup()` functions and the HTTP/STUN dissectors. In the unit tests output, a print about `ndpi_protocol->protocol_by_ip` has been added for each flow: the huge diff of this commit is mainly due to that. Strictly speaking, this change is NOT an API/ABI breakage, but there are important differences in the classification results. For examples: * TLS flows without the initial handshake (or without a matching SNI/certificate) are simply classified as `TLS`; * similar for HTTP or QUIC flows; * DNS flows without a matching request domain are simply classified as `DNS`; we don't have `DNS/Google` anymore just because the server is 8.8.8.8 (that was an outrageous behaviour...); * flows previusoly classified only "by-ip" are now classified as `NDPI_PROTOCOL_UNKNOWN`. See #1425 for other examples of why adding the "classification by-ip" in the protocol stack is a bad idea. Please, note that IPV6 is not supported :( (long standing issue in nDPI) i.e. `ndpi_protocol->protocol_by_ip` wil be always `NDPI_PROTOCOL_UNKNOWN` for IPv6 flows. Define `NDPI_CONFIDENCE_MATCH_BY_IP` has been removed. Close #1687

* Fix `ndpi_do_guess()` (#1731)Ivan Nardi2022-09-12
| | | | | Avoid a double call of `ndpi_guess_host_protocol_id()`. Some code paths work for ipv4/6 both Remove some never used code.
* STUN: several improvementsNardi Ivan2022-09-11
| | | | | | | | | Add detection over TCP and fix detection over IPv6. Rename some variables since Stun dissector is no more "udp-centric". Stun dissector should always classified the flow as `STUN` or `STUN/Something`. Don't touch `flow->guessed_host_protocol_id` field, which should be always be related to "ip-classification" only.
* Avoid useless host automa lookup (#1724)Ivan Nardi2022-09-05
| | | | | | | | | | | | | | | | | | | The host automa is used for two tasks: * protocol sub-classification (obviously); * DGA evaluation: the idea is that if a domain is present in this automa, it can't be a DGA, regardless of its format/name. In most dissectors both checks are executed, i.e. the code is something like: ``` ndpi_match_host_subprotocol(..., flow->host_server_name, ...); ndpi_check_dga_name(..., flow->host_server_name,...); ``` In that common case, we can perform only one automa lookup: if we check the sub-classification before the DGA, we can avoid the second lookup in the DGA function itself.

* TLS: avoid useless extra dissection (#1690)Ivan Nardi2022-07-31
| | | | | | | If we have seen Application Data blocks in both directions, it means we are after the handshake. At that point, extra dissection is useless. Useful feature with TLS mid-sessions, i.e. sessions without initial packets.
* HTTP: fix classification (#1692)Ivan Nardi2022-07-30
| | | | | | | | | | If we have a valid HTTP sessions, we should ignore `flow->guessed_protocol_id` field (i.e. classification "by-port") altogheter. The attached trace was classified as "SIP/HTTP" only because the *client* port was 5060... As a general rule, having a classification such as "XXXX/HTTP" is *extremely* suspicious.

* Patricia tree, Ahocarasick automa, LRU cache: add statistics (#1683)Ivan Nardi2022-07-29
| | | | | | | | | | Add (basic) internal stats to the main data structures used by the library; they might be usefull to check how effective these structures are. Add an option to `ndpiReader` to dump them; enabled by default in the unit tests. This new option enables/disables dumping of "num dissectors calls" values, too (see b4cb14ec).
* TINC: avoid processing SYN packets (#1676)Ivan Nardi2022-07-28
| | | | | | | | | | | Since e6b332aa, we have proper support for detecting client/server direction. So Tinc dissector is now able to properly initialize the cache entry only when needed and not anymore at the SYN time; initializing that entry for **every** SYN packets was a complete waste of resources. Since 4896dabb, the various `struct ndpi_call_function_struct` structures are not more separate objects and therefore comparing them using only their pointers is bogus: this bug was triggered by this change because `ndpi_str->callback_buffer_size_tcp_no_payload` is now 0.

* Add support for flow client/server information (#1671)Ivan Nardi2022-07-24
| | | | | | | | | | | | | | | | | | In a lot of places in ndPI we use *packet* source/dest info (address/port/direction) when we are interested in *flow* client/server info, instead. Add basic logic to autodetect this kind of information. nDPI doesn't perform any "flow management" itself but this task is delegated to the external application. It is then likely that the application might provide more reliable hints about flow client/server direction and about the TCP handshake presence: in that case, these information might be (optionally) passed to the library, disabling the internal "autodetect" logic. These new fields have been used in some LRU caches and in the "guessing" algorithm. It is quite likely that some other code needs to be updated.
