| | | | | | | * nDPIsrvd.h: iterate over subtokens * nDPIsrvd-captured: select/ unselect risky flows to capture Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Unified IO buffer mgmt.Toni Uhlig2021-06-07
| | | | | | | * c-collectd gives the user control over collectd-exec instance name * added missing collectd type `flow_l4_icmp_count` Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Added nDPId semantic validation test.Toni Uhlig2021-04-14
| | | | | | | | | | | * fixed inconsistent processing of remaining flows during nDPId shutdown phase * fixed multiple `detected' flow events (instead only `detection-update' flow events can occur after a `detected' flow event) * fixed nDPIsrvd.py invalid message buffer handling * improved run_tests.sh so only valid pcap capture files are getting processed (and some more cosmetics + logging) Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Fixed nDPIsrvd.h flow end bug (flow end callback could never be called and ↵Toni Uhlig2021-04-11

| | | | | | | | | | | | | | re-using most of nDPId/nDPIsrvd core) * improved Makefile.old install targets * splitted nDPIsrvd_parse into nDPIsrvd_parse_line and nDPIsrvd_parse_all for the sake of readability * minor Python script improvments (check for nDPIsrvd.py on multiple locations, may be superseeded by setuptools in the future) * some paths needs to be absolute (chdir() during daemonize) and therefor additional checks introduced * test run script checks and fails if certain files are are missing (PCAP file <=> result output file) * removed not very useful "internal format error" JSON serialization if a BUG for same exists * fixed invalid l4 type statistics counters for nDPIsrvd-collectd 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.

* 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>
