CI duration is quite long: the longest jobs is the "Performance" one.
Try to reduce the overall duration: that job (and some others) will not
be triggered for each PR/commit anymore, but asynchronously, once a day
(this scheduling seems right since the frequency of the PR/commits in
the project).
It should be possibly to trigger them manually, via GUI, anyway.
Remove two identical jobs; we already tests ASAN with 4 different
compilers.
After 9eff0754 it is safe to reduce fuzzing time.
Bottom line: try to have as upper-time of CI tests the duration of the
fuzzing jobs
Autodetecting the needed buffer size is quite complex (especially with
float/double values) so it is mandatory to properly check for
`ndpi_snprintf` truncation.
These issues have been undetected so far probably because the default
buffer is big enough for all common cases.
Add an example of usage of `ndpi_deserialize_clone_all()` (taken from
`ntopng`)
The goal of this fuzzer is to test init and deinit of the library, with
different configurations. In details:
* random memory allocation failures, even during init phase
* random `ndpi_init_prefs` parameter of `ndpi_init_detection_module()`
* random LRU caches sizes
* random bitmask of enabled protocols
* random parameters of `ndpi_set_detection_preferences()`
* random initialization of opportunistic TLS
* random load/don't load of configuration files
This new fuzzer is a C++ file, because it uses `FuzzedDataProvider`
class (see
https://github.com/google/fuzzing/blob/master/docs/split-inputs.md).
Note that the (existing) fuzzers need to be linked with C++ compiler
anyway, so this new fuzzer doesn't add any new requirements.
QUIC packets are encrypted/obfuscated; that means that we need to
decrypt them before parsing the real (TLS) message.
Fuzzing is not effective here, since a random buffer is hardly a valid
encrypted QUIC packet.
Add a new fuzzer, testing *decrypted* QUIC packets.
Add a basic corpus.
Fix a few bugs already found by this fuzzer.
