* 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

* RTP/STUN: look for STUN packets after RTP/RTCP classification (#2465)Ivan Nardi2024-06-07
| | | | | | | | | | After a flow has been classified as RTP or RTCP, nDPI might analyse more packets to look for STUN/DTLS packets, i.e. to try to tell if this flow is a "pure" RTP/RTCP flow or if the RTP/RTCP packets are multiplexed with STUN/DTLS. Useful for proper (sub)classification when the beginning of the flows are not captured or if there are lost packets in the the captured traffic. Disabled by default

* RTP: fix detection over TCP (#2462)Ivan Nardi2024-05-29
| | | | | | RFC4571 is not the only way to wrap RTP messages in TCP streams. For example, when RTP is encapsulated over TURN flows (i.e. via DATA attribute) there is no additional framing. See also 6127e0490

* Raknet/RTP: avoid Raknet false positives and harden RTP heuristic (#2427)Ivan Nardi2024-05-09
| | | | | | | | | There is some overlap between RTP and Raknet detection: give precedence to RTP logic. Consequences: * Raknet might require a little bit more packets for some flows (not a big issue) * some very small (1-2 pkts) Raknet flows are not classified (not sure what do do about that..)

* 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.
* Merge RTP and RTCP logic (#2416)Ivan Nardi2024-05-06
| | | | | | | | | Avoid code duplication between these two protocols. We remove support for RTCP over TCP; it is quite rare to find this kind of traffic and, more important, we have never had support for RTP over TCP: we should try to add both detecion as follow-up. Fix a message log in the LINE code
* Remove PPStream protocol and add iQIYI (#2403)0x41CEA552024-04-23
| | | | | | P2P video player PPStream was discontinued shortly after the purchase of PPS.tv by Baidu (iQIYI) on 2013 (see https://www.techinasia.com/report-baidu-acquires-video-rival-pps) So we remove the old `NDPI_PROTOCOL_PPSTREAM` logic and add `NDPI_PROTOCOL_IQIYI` id to handle all the iQIYI traffic, which is basically video streaming traffic. A video hosting service, called PPS.tv, is still offered by the same company: for the time being we classified both services with the same protocol id.

* Domain Classification Improvements (#2396)Luca Deri2024-04-18
| | | | | | | | | | | | | | | | | | | * Added size_t ndpi_compress_str(const char * in, size_t len, char * out, size_t bufsize); size_t ndpi_decompress_str(const char * in, size_t len, char * out, size_t bufsize); used to compress short strings such as domain names. This code is based on https://github.com/Ed-von-Schleck/shoco * Major code rewrite for ndpi_hash and ndpi_domain_classify * Improvements to make sure custom categories are loaded and enabled * Fixed string encoding * Extended SalesForce/Cloudflare domains list

* 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.

* Improve normalization of `flow->host_server_name` (#2310)Ivan Nardi2024-02-09
| | | | | | | | | | | | | Follow-up of 4543385d107fcc5a7e8632e35d9a60bcc40cb4f4 Remove trailing spaces for any HTTP header (we already remove leading spaces) We want: * a "normalized" string in `flow->host_server_name`, but * to parse the original string for flow risk checking `ndpi_hostname_sni_set()` is a private function, so there is no need to export its flags.

* Allow multiple `struct ndpi_detection_module_struct` to share some state (#2271)Ivan Nardi2024-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the concept of "global context". Right now every instance of `struct ndpi_detection_module_struct` (we will call it "local context" in this description) is completely independent from each other. This provide optimal performances in multithreaded environment, where we pin each local context to a thread, and each thread to a specific CPU core: we don't have any data shared across the cores. Each local context has, internally, also some information correlating **different** flows; something like: ``` if flow1 (PeerA <-> Peer B) is PROTOCOL_X; then flow2 (PeerC <-> PeerD) will be PROTOCOL_Y ``` To get optimal classification results, both flow1 and flow2 must be processed by the same local context. This is not an issue at all in the far most common scenario where there is only one local context, but it might be impractical in some more complex scenarios. Create the concept of "global context": multiple local contexts can use the same global context and share some data (structures) using it. This way the data correlating multiple flows can be read/write from different local contexts. This is an optional feature, disabled by default. Obviously data structures shared in a global context must be thread safe. This PR updates the code of the LRU implementation to be, optionally, thread safe. Right now, only the LRU caches can be shared; the other main structures (trees and automas) are basically read-only: there is little sense in sharing them. Furthermore, these structures don't have any information correlating multiple flows. Every LRU cache can be shared, independently from the others, via `ndpi_set_config(ndpi_struct, NULL, "lru.$CACHE_NAME.scope", "1")`. It's up to the user to find the right trade-off between performances (i.e. without shared data) and classification results (i.e. with some shared data among the local contexts), depending on the specific traffic patterns and on the algorithms used to balance the flows across the threads/cores/local contexts. Add some basic examples of library initialization in `doc/library_initialization.md`. This code needs libpthread as external dependency. It shouldn't be a big issue; however a configure flag has been added to disable global context support. A new CI job has been added to test it. TODO: we should need to find a proper way to add some tests on multithreaded enviroment... not an easy task... *** API changes *** If you are not interested in this feature, simply add a NULL parameter to any `ndpi_init_detection_module()` calls.
