* STUN: remove workaround to identify RTP trafficNardi Ivan2024-03-20
| | | | | We are able to demultiplex RTP packets in STUN flows since 3608ab01b, at least; no need to explicity call the RTP dissector

* LRU cache: move to 64 bits long keys (#2346)Ivan Nardi2024-03-15
| | | | | | Tradeoff between key comparison efficiency (i.e. no `memcmp`) and key length. At least in the ipv4 cases, we have no more different entries with the same key.

* 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

* TLS: avoid setting some flow risks for webrtc trafficNardi Ivan2024-02-26
| | | | | Is quite rare to have a SNI or an ALPN on Client Hello of STUN/DTLS/SRTP traffic
* Telegram: improve identificationNardi Ivan2024-02-26
| | | | | | | | | | | | | | | | | Follow up of 31c706c3dbbf0afc4c8e0a6d0bb6f20796296549 and 75485e177ccc4fafcc62dd46c6917d5b735cf7d2. Allow fast classification by ip, but give time to other dissectors to kick in (for example, the TLS code for the Telegram Web flows). Even if we don't classify it anymore at the very first packet (i.e. SYN) we fully classify Telegram traffic at the first packet with payload, as *any* other protocol. This way, we always have the proper category, the proper confidence for the UDP flows and we don't overwrite previous classifications (TLS or ICMP) Remove old and stale identification logic for TCP 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.
