Try using latest gcc and clang versions.
We still care about RHEL7: since handling a RHEL7 runner on GitHub is
quite complex, let try to use a similar version of gcc, at least
Keep looking for RTP packets but remove the monitoring concept.
We will re-introduce a more general concept of "flow in monitoring
state" later.
The function was disabled by default.
Some configuration knobs will be provided when/if #2190 is merged.
* logging is instead redirected to `ndpi_debug_printf`

approach for handling Internet domain names.
For switching back to Aho-Corasick it is necessary to edit
ndpi-typedefs.h and uncomment the line
// #define USE_LEGACY_AHO_CORASICK
[1] With Aho-Corasick
$ ./example/ndpiReader -G ./lists/ -i tests/pcap/ookla.pcap | grep Memory
nDPI Memory statistics:
nDPI Memory (once): 37.34 KB
Flow Memory (per flow): 960 B
Actual Memory: 33.09 MB
Peak Memory: 33.09 MB
[2] With the new algorithm
$ ./example/ndpiReader -G ./lists/ -i tests/pcap/ookla.pcap | grep Memory
nDPI Memory statistics:
nDPI Memory (once): 37.31 KB
Flow Memory (per flow): 960 B
Actual Memory: 7.42 MB
Peak Memory: 7.42 MB
In essence from ~33 MB to ~7 MB
This new algorithm will enable larger lists to be loaded (e.g. top 1M domans
https://s3-us-west-1.amazonaws.com/umbrella-static/index.html)
In ./lists there are file names that are named as <category>_<string>.list
With -G ndpiReader can load all of them at startup
The option NSID (RFC5001) is used by Google DNS to report the
airport code of the metro where the DNS query is handled.
This option is quite rare, but the added overhead in DNS code is pretty
much zero for "normal" DNS traffic
Use two separate lists:
* one for the ingress nodes, which triggers a ProtonVPN classification
* one for the egress nodes, which triggers the
`NDPI_ANONYMOUS_SUBSCRIBER` risk
Add a command line option (to `ndpiReader`) to easily test IP/port
matching.
Add another example of custom rule.
* added feature to extract filename from http attachment
* fixed some issues
* added check for filename format
* added check for filename format
* remove an unnecessary print
* changed the size from 952 to 960
* modified some test result files
* small changes string size
* comment removed and mallocs checked
The two fields `flow->flow_type` and `flow->protos.rtp.stream_type` are
pretty much identical: rename the former in `flow->flow_multimedia_type`
and remove the latter.
