* websocket: `ndpi_set_detected_protocol()` should be called only onceHEADdevIvan Nardi5 days
| | | | Fix: b07a910dc
* Refactor: make src_name/dst_name dynamically allocated to reduce RAM usage ↵Fábio Depin5 days
| | | | | | (#2908) - Changed ndpi_flow_info: replaced fixed-size char arrays (always INET6_ADDRSTRLEN) for src_name and dst_name with char* pointers. - Now IPv4 flows use only INET_ADDRSTRLEN when needed, instead of always reserving IPv6 size.

* Fix logic: reset stats once per thread after clearing all flow roots (#2905)Fábio Depin12 days
| | | | | | | Call ndpi_stats_reset() once per thread instead of once per flow root Moved ndpi_stats_reset() outside the loop that destroys ndpi_flows_root[] to avoid redundant resets. The stats structure is shared per thread and should only be reset once after all roots are cleared.

* Fix stats memory reuse and cleanup across duration loops in ndpiReader ↵Fábio Depin13 days
| | | | | | | | | | | | | | (#2903) (#2904) Refactored stats allocation and reset logic to avoid segmentation faults when running ndpiReader in live_capture mode with the -m (duration) option. - Introduced ndpi_stats_init(), ndpi_stats_reset(), and ndpi_stats_free() to encapsulate lifecycle management of stats. - Applied these functions in ndpiReader.c and reader_util.{c,h}. - Prevented multiple allocations and ensured safe reuse of cumulative_stats and per-thread stats structures between capture iterations.

* New API to enable/disable protocols. Removed ↵Ivan Nardi13 days
| | | | | | | | | | | | | | | | | | | | | | | | | | `NDPI_LAST_IMPLEMENTED_PROTOCOL` (#2894) Change the API to enable/disable protocols: you can set that via the standard `ndpi_set_config()` function, as every configuration parameters. By default, all protocols are enabled. Split the (local) context initialization into two phases: * `ndpi_init_detection_module()`: generic part. It does not depend on the configuration and on the protocols being enabled or not. It also calculates the real number of internal protocols * `ndpi_finalize_initialization()`: apply the configuration. All the initialization stuff that depend on protocols being enabled or not must be put here This is the last step to have the protocols number fully calculated at runtime Remove a (now) useless fuzzer. Important API changes: * remove `NDPI_LAST_IMPLEMENTED_PROTOCOL` define * remove `ndpi_get_num_internal_protocols()`. To get the number of configured protocols (internal and custom) you must use `ndpi_get_num_protocols()` after having called `ndpi_finalize_initialization()`
