* Fix Grease values parsing (#1416)havsah2022-01-21
| | | | | | | | | | | The check for grease was too broad and filtered some valid values. In particular, the value 257 was skipped because it matched the previous check. This has been discovered while parsing tests/pcap/443-firefox.pcap expected ja3: 771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256-257,0 previously generated ja3: 771,4865-4867-4866-49195-49199-52393-52392-49196-49200-49162-49161-49171-49172-51-57-47-53-10,0-23-65281-10-11-35-16-5-51-43-13-45-28-21,29-23-24-25-256,0 Signed-off-by: Patrick Havelange <patrick.havelange_ext@softathome.com>

* build: respect environment options more (#1392)Sam James2022-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * build: update m4/ax_pthread.m4 from serial 23 -> serial 31 Update ax_pthread.m4 to the latest version from the autoconf-archive project. Signed-off-by: Sam James <sam@gentoo.org> * build: properly detect AR, CC, RANLIB It's necessary to be able to override choice of AR/CC/RANLIB and other toolchain variables/tools for cross-compilation, testing with other toolchains, and to ensure the compiler chosen by the user is actually used for the build. Previously, GNU_PREFIX was kind-of used for this but this isn't a standard variable (at all) and it wasn't applied consistently anyway. We now use the standard autoconf mechanisms for finding these tools. (RANLIB is already covered by LT_INIT.) Signed-off-by: Sam James <sam@gentoo.org> * build: use $(MAKE) This ensures that parallel make works correctly, as otherwise, a fresh make job will be started without the jobserver fd, and hence not know about its parent, forcing -j1. * build: respect CPPFLAGS, LDFLAGS - CPPFLAGS is for the C preprocessor (usually for setting defines) - LDFLAGS should be placed before objects for certain flags to work (e.g. -Wl,--as-needed) Signed-off-by: Sam James <sam@gentoo.org> Co-authored-by: Luca Deri <lucaderi@users.noreply.github.com>

* Add a "confidence" field about the reliability of the classification. (#1395)Ivan Nardi2022-01-11
| | | | | | | | | | | | | As a general rule, the higher the confidence value, the higher the "reliability/precision" of the classification. In other words, this new field provides an hint about "how" the flow classification has been obtained. For example, the application may want to ignore classification "by-port" (they are not real DPI classifications, after all) or give a second glance at flows classified via LRU caches (because of false positives). Setting only one value for the confidence field is a bit tricky: more work is probably needed in the next future to tweak/fix/improve the logic.

* 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.

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.
