* Added optimized memmem/strlcpy version (#2424)Toni2024-05-08
| | | | | * credits goes to Vladimir Gavrilov Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Reworked code and added two new API callsLuca Deri2024-05-07
| | | | | - int ndpi_load_ipv4_ptree_file(ndpi_ptree_t *tree, const char *path, u_int16_t protocol_id); - int ndpi_load_ipv6_ptree_file(ndpi_ptree_t *tree, const char *path, u_int16_t protocol_id);

* 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.
* TLS: avoid setting `NDPI_TLS_SELFSIGNED_CERTIFICATE` for webrtc traffic (#2417)Ivan Nardi2024-05-06
| | | | | | See RFC8122: it is quite likely that STUN/DTLS/SRTP flows use self-signed certificates Follow-up of b287d6ec8
* 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
* eDonkey: improve/update classification (#2410)Ivan Nardi2024-05-04
| | | | | | | | | | eDonkey is definitely not as used as >10 years ago, but it seems it is still active. While having a basic TCP support seems easy, identification over UDP doesn't work and it is hard to do it rightly (packets might be only 2 bytes long): remove it.

* Add Adobe Connect support (#2407)0x41CEA552024-04-24

* 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.
* Add BFCP protocol support (#2401)0x41CEA552024-04-23

* Fix a warningNardi Ivan2024-04-20

* 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.

| | | | Modified NDPI_BINARY_TRANSFER_ATTEMPT in NDPI_BINARY_DATA_TRANSFER
* 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.

* ahocorasick: improve matching with subdomains (#2331)Ivan Nardi2024-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The basic idea is to have the following logic: * pattern "DOMAIN" matches the domain itself (i.e exact match) *and* any subdomains (i.e. "ANYTHING.DOMAIN") * pattern "DOMAIN." matches *also* any strings for which is a prefix [please, note that this kind of match is handy but it is quite dangerous...] * pattern "-DOMAIN" matches *also* any strings for which is a postfix Examples: * pattern "wikipedia.it": * "wikipiedia.it" -> OK * "foo.wikipedia.it -> OK * "foowikipedia.it -> NO MATCH * "wikipedia.it.com -> NO MATCH * pattern "wikipedia.": * "wikipedia.it" -> OK * "foo.wikipedia.it -> OK * "foowikipedia.it -> NO MATCH * "wikipedia.it.com -> OK * pattern "-wikipedia.it": * "wikipedia.it" -> NO MATCH * "foo.wikipedia.it -> NO MATCH * "0001-wikipedia.it -> OK * "foo.0001-wikipedia.it -> OK Bottom line: * exact match * prefix with "." (always, implicit) * prefix with "-" (only if esplicitly set) * postfix with "." (only if esplicitly set) That means that the patterns cannot start with '.' anymore. Close #2330
