* QUIC: add support for version 2 draft 01 (#1493)Ivan Nardi2022-03-25
| | | | | | Support for v2-00 has been removed (it has never been used in real networks and it is incompatible with v2-01). Chrome already supports v2-01 in latest versions in Chrome Beta channel.
* QUIC: fix dissection of draft-34 (#1484)dev-1Ivan Nardi2022-03-09
| | | | QUIC-34 is probably not used in production, but fixing it is trivial and it doesn't add any noise to the already complex QUIC code.
* Extend tests coverage (#1476)Ivan Nardi2022-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now there is at least one flow under `tests/pcap` for 249 protocols out of the 284 ones supported by nDPI. The 35 protocols without any tests are: * P2P/sharing protocols: DIRECT_DOWNLOAD_LINK, OPENFT, FASTTRACK, EDONKEY, SOPCAST, THUNDER, APPLEJUICE, DIRECTCONNECT, STEALTHNET * games: CSGO, HALFLIFE2, ARMAGETRON, CROSSFIRE, DOFUS, FIESTA, FLORENSIA, GUILDWARS, MAPLESTORY, WORLD_OF_KUNG_FU * voip/streaming: VHUA, ICECAST, SHOUTCAST, TVUPLAYER, TRUPHONE * other: AYIYA, SOAP, TARGUS_GETDATA, RPC, ZMQ, REDIS, VMWARE, NOE, LOTUS_NOTES, EGP, SAP Most of these protocols (expecially the P2P and games ones) have been inherited by OpenDPI and have not been updated since then: even if they are still used, the detection rules might be outdated. However code coverage (of `lib/protocols`) only increases from 65.6% to 68.9%. Improve Citrix, Corba, Fix, Aimini, Megaco, PPStream, SNMP and Some/IP dissection. Treat IPP as a HTTP sub protocol. Fix Cassandra false positives. Remove `NDPI_PROTOCOL_QQLIVE` and `NDPI_PROTOCOL_REMOTE_SCAN`: these protocol ids are defined but they are never used. Remove Collectd support: its code has never been called. If someone is really interested in this protocol, we can re-add it later, updating the dissector. Add decoding of PPI (Per-Packet Information) data link type.
* Internal crypto: increase size of authentication buffer (#1468)Ivan Nardi2022-03-02
| | | | | | | Some QUIC flows are not properly decoded while using internal crypto code: the authentication buffer is too small. The new value (like the old one) is arbitrary. Close #1463
* Add ICMP checksum check and set risk if mismatch detected. (#1464)Toni2022-03-02
| | | Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* Add few scripts to easily update some IPs lists (#1436)Ivan Nardi2022-02-09
| | | | | | | | | | | | | | | | | | | | | | | | * Add few scripts to easily update some IPs lists Some IPs lists should be updated frequently: try to easy the process. The basic idea is taken from d59fefd0 and a8fe74e5 (for Azure addresses): one specific .c.inc file and one script for each protocol. Add the possibility to don't load a specific list. Rename the old NDPI_PROTOCOL_HOTMAIL id to NDPI_PROTOCOL_MS_OUTLOOK, to identify Hotmail/Outlook/Exchange flows. TODO: ipv6 Remove the 9 addresses associated to BitTorrent: they have been added in e2f21116 but it is not clear why all the traffic to/from these ips should be classified as BitTorrent. * Added quotes * Added quotes Co-authored-by: Luca Deri <lucaderi@users.noreply.github.com>

| | | | PS VUE service has been discontinued on January 30, 2020 https://en.wikipedia.org/wiki/PlayStation_Vue
* Extend protocols support (#1422)Ivan Nardi2022-01-29
| | | | | | | | | | | | | | | | | | Add detection of AccuWeather site/app and Google Classroom. Improve detection of Azure, Zattoo, Whatsapp, MQTT and LDAP. Fix some RX false positives. Fix some "Uncommon TLS ALPN"-risk false positives. Fix "confidence" value for some Zoom/Torrent classifications. Minor fix in Lua script for Wireshark extcap. Update .gitignore file. Let GitHub correctly detect the language type of *.inc files. Zattoo example has been provided by @subhajit-cdot in #1148.

* A final(?) effort to reduce memory usage per flow (#1389)Ivan Nardi2021-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove some unused fields and re-organize other ones. In particular: * Update the parameters of `ndpi_ssl_version2str()` function * Zattoo, Thunder: these timestamps aren't really used. * Ftp/mail: these protocols are dissected only over TCP. * Attention must be paid to TLS.Bittorrent flows to avoid invalid read/write to `flow->protos.bittorrent.hash` field. This is the last(?) commit of a long series (see 22241a1d, 227e586e, 730c2360, a8ffcd8b) aiming to reduce library memory consumption. Before, at nDPI 4.0 (more precisly, at a6b10cf7, because memory stats were wrong until that commit): ``` nDPI Memory statistics: nDPI Memory (once): 221.15 KB Flow Memory (per flow): 2.94 KB ``` Now: ``` nDPI Memory statistics: nDPI Memory (once): 231.71 KB Flow Memory (per flow): 1008 B <--------- ``` i.e. memory usage per flow has been reduced by 66%, dropping below the psychological threshold of 1 KB. To further reduce this value, we probably need to look into #1279: let's fight this battle another day.
* Improve/add several protocols (#1383)Ivan Nardi2021-12-18
| | | | | | | | | | | | | | | | | | | Improve Microsoft, GMail, Likee, Whatsapp, DisneyPlus and Tiktok detection. Add Vimeo, Fuze, Alibaba and Firebase Crashlytics detection. Try to differentiate between Messenger/Signal standard flows (i.e chat) and their VOIP (video)calls (like we already do for Whatsapp and Snapchat). Add a partial list of some ADS/Tracking stuff. Fix Cassandra, Radius and GTP false positives. Fix DNS, Syslog and SIP false negatives. Improve GTP (sub)classification: differentiate among GTP-U, GTP_C and GTP_PRIME. Fix 3 LGTM warnings.
* QUIC: add support for QUICv2 (draft 00) (#1379)Ivan Nardi2021-12-04
| | | | It is already time to start looking at the new QUIC version. See: https://datatracker.ietf.org/doc/html/draft-ietf-quic-v2-00
* Added Salesforce detectionLuca Deri2021-11-26
