* C-Api uses similiar flow key hash calculation as Python-Api.Toni Uhlig2021-02-19
| | | | | | * Make use of flow id / alias / source which is required for future use cases where multiple nDPId instances (same / different machines) feed one nDPIsrvd. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Added JSON schema files and a Python schema validator.Toni Uhlig2021-02-17
| | | | Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Aligned nDPIsrvd.py to nDPIsrvd.h for consistency.Toni Uhlig2021-02-16
| | | | | | | | | * Simplified Python interface as well. * c-captured and flow-undetected-to-pcap.py produce similiar results * Removed overloaded nDPIsrvd.py event structures. * flow-info.py prints (with a color-hash) additional information e.g. alias/source and midstream Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Removed superfluous nDPI (header) dependency for examples/c-captured. Use ↵Toni Uhlig2021-02-06
| | | | | | header definitions from libc instead. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* nDPIsrvd C API overhaul and massive simplification.Toni Uhlig2021-02-06
| | | | | | | | * nDPIsrvd.h does flow mgmt out of the box * dissect received JSON strings via callback * added new JSON key/values for packet-flows (usecTimestamp/L3/L4 info) Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Fixed braindead failure - Increase of NETWORK_BUFFER_MAX_SIZE > 9999 means ↵Toni Uhlig2021-01-27
| | | | | | | | | to also increase NETWORK_BUFFER_LENGTH_DIGITS to 5. * Fixed ARM32 xcompile warnings; Other GCC versions, other uint64_t's.. * Replaced ridiculous nDPIsrvd_JSON_BYTES with NETWORK_BUFFER_LENGTH_DIGITS. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Increased JSON buffer size to 12288 (libnDPI serializes more and more ↵Toni Uhlig2021-01-27
| | | | | | | | | | | information). * Making Compare&Fetch mandatory. * Added some more Compare&Fetch to prevent TSAN complaining about data races. Fixed possible but more ore less harmless data races during shutdown process. * Shrink SIGNAL handler to a minimum. SYSV Signal handling and MT-safety is awkward. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* Declared nDPI id and flow structs in nDPId flow info struct.Toni Uhlig2020-12-30
| | | | | | | | Two reasons: * reduce heap memory allocations * nDPId flow info struct may be inflated in the future (more bytes to compress) Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Removed all LUA leftover as preparation for UTHASH.Toni Uhlig2020-12-01
| | | | | | * Added UNIX socket support for nDPIsrvd.h (and c-captured) Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Let travis use pcap files from nDPI to produce some JSON output. (disabled, ↵Toni Uhlig2020-12-01
| | | | | | | | | | | needs further testing..) * Added pcap diff script * Added \n to JSON string end (useful for debugging and readability) * Use first host/server name character for hash calculation as well * Removed error'ing EPOLLHUP handling in nDPIsrvd (connection closing will be detected via read()) Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Increased serialization buffer size as required for recent nDPI builds.Toni Uhlig2020-11-18
