* bump libnDPI to ...Toni Uhlig2023-05-24
| | | | | | | | * upstream changed regression test interface, needed to adapt * improved libnDPI helper build script * updated JSON schema Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Moved `datalink` json key/value from error to packet events and renamed it ↵Toni Uhlig2023-04-21

* Improved the point of time when to append the raw packet base64 data to the ↵Toni Uhlig2022-11-15
| | | | | | | | | serializer. * nDPId-test: Increased the max-packets-per-flow-to-send from 3 to 5. This is quite useful for TCP as the first 3 packets are usually part of the three-way-handshake. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* Added nDPIsrvd-analysed to generate CSV files from analyse events.Toni Uhlig2022-09-30
| | | | | | | * nDPIsrvd.h: iterate over JSON arrays * nDPId: calculate l3 payload packet entropies for analysis Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Refactored client distributor C API.Toni Uhlig2022-09-25
| | | | | | | | | | | * Still not perfect, but the code before was not even able to deal with JSON arrays. Use common "speaking" function names for all functions in nDPIsrvd.h * Provide a more or less generic and easy extendable JSON walk function. * Modified C examples to align with the changed C API. * c-collectd: Reduced lot's of code duplication by providing mapping tables. * nDPId: IAT array requires one slot less (first packet has always an IAT of 0).

* New flow event: 'analysis'.Toni Uhlig2022-09-13
| | | | | | | | | * The goal was to provide a separate event for extracted feature that are not required and only useful for a few (e.g. someone who wants do ML). * Increased network buffer size to 32kB (8192 * 4). * Switched timestamp precision from ms to us for *ALL* timestamps.
