* Improved the point of time when to append the raw packet base64 data to the ↵Toni Uhlig2022-11-15

* 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>
