* 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.

* Added daemon event: DAEMON_EVENT_STATUS (periodically send's daemon statistics.)Toni Uhlig2022-03-06
| | | | | | | | | | * Improved distributor timeout handling (per-thread). * flow-info.py / flow-dash.py: Distinguish between flow risk severities. * nDPId: Skip tag switch datalink packet dissection / processing. * nDPId: Fixed incorrect value for current active flows. * Improved JSON schema's. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Added additional (minimalistic) detection information to flow updates.Toni Uhlig2022-02-04
| | | | | | | | | | | | | This will only affect flows with the state `FT_FINISHED' (detection done). * nDPIsrvd.py: force use of JSON schema Draft 7 validator * flow-dash.py: gather/use total processed layer4 payload size * flow-info.py: added additional event filter * flow-info.py: prettified flow events printing whose detection is in progress * py-semantic-validation.py: added validation checks for FT_FINISHED * updated flow event JSON schema Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

| | | | | | | | | * bump libnDPI to c53c82d4823b5a8f856d1375155ac5112b68e8af * run_tests.sh: improved execution from non-git directories e.g. via `make dist` * updated JSON schema to be more restrictive * nDPId: splitted generic get_ip_from_sockaddr into IPv4/IPv6 to prevent compiler warnings on some platforms Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* nDPId: Added some error messages when workflow init fails.Toni Uhlig2022-01-26

* Major nDPId extension. Sorry for the huge commit.Toni Uhlig2022-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - nDPId: fixed invalid IP4/IP6 tuple compare - nDPIsrvd: fixed caching issue (finally) - added tiny c example (can be used to check flow manager sanity) - c-captured: use flow_last_seen timestamp from `struct nDPIsrvd_flow` - README.md update: added example JSON sequence - nDPId: added new flow event `update` necessary for correct timeout handling (and other future use-cases) - nDPIsrvd.h and nDPIsrvd.py: switched to an instance (consists of an alias/source tuple) based flow manager - every flow related event **must** now serialize `alias`, `source`, `flow_id`, `flow_last_seen` and `flow_idle_time` to make the timeout handling and verification process work correctly - nDPIsrvd.h: ability to profile any dynamic memory (de-)allocation - nDPIsrvd.py: removed PcapPacket class (unused) - py-flow-dashboard and py-flow-multiprocess: fixed race condition - py-flow-info: print statusbar with probably useful information - nDPId/nDPIsrvd.h: switched from packet-flow only timestamps (`pkt_*sec`) to a generic flow event timestamp `ts_msec` - nDPId-test: added additional checks - nDPId: increased ICMP flow timeout - nDPId: using event based i/o if capturing packets from a device - nDPIsrvd: fixed memory leak on shutdown if remote descriptors were still connected Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Fixed invalid "flow_last_seen" timestamp for the first packet.Toni Uhlig2021-10-08
| | | | | | | | | | * After the first packet was processed, "flow_last_seen" was still 0. This behaviour is invalid as the first packet may contain l4 payload data e.g. for UDP and it also breaks nDPId json consistency "flow_first_seen" > 0, but "flow_last_seen" == 0. * JSON schema: set minimum timestamp value for Epoch timestamps to 24710 for flow_*_seen and 1 for pcap packet ts. Those values are dependant on some manipulated pcap's in libnDPI/tests/pcap. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Reworked layer 4 flow length naming/calculation.Toni Uhlig2021-05-20
| | | | | | | * nDPIsrvd services usually do not care about layer4 data length, payload length is quite more essential for further processing Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Added nDPId-test as all-in-one JSON dumper.Toni Uhlig2021-03-24
| | | | | | | | | * fixed invalid flow event schema type * added run_tests.sh to generate/diff JSON dumps * renamed lot's of vars/fns in nDPId.c/nDPIsrvd.c, so nDPId-test.c can include "*.c" * improved CMake dependency checks Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Extended nDPIsrvd.h with address parsing.Toni Uhlig2021-02-23
| | | | | | | | | * nDPId supports looading of custom nDPI protocol/category files * extended JSON schemas according to nDPI / nDPId JSON serializing * removed memory holes in nDPId * extended examples/c-captured Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Added JSON schema files and a Python schema validator.Toni Uhlig2021-02-17
