* fuzz: extend fuzzing coverageIvan Nardi2025-06-24
| | | | Remove some unused code
* If `NDPI_KNOWN_PROTOCOL_ON_NON_STANDARD_PORT` risk is disabled, avoid some ↵Ivan Nardi2025-06-23
| | | | work (#2899)
* Faster configuration (#2887)Ivan Nardi2025-06-17
|
* Rename `ndpi_bitmask_dealloc` into `ndpi_bitmask_free`Ivan Nardi2025-06-09
|
* Remove `NDPI_PROTOCOL_BITMASK`; add a new generic bitmask data structure (#2871)Ivan Nardi2025-06-09
| | | | | | | | | | | | | | | | | | | The main difference is that the memory is allocated at runtime Typical usercase: ``` struct ndpi_bitmask b; ndpi_bitmask_alloc(&b, ndpi_get_num_internal_protocols()); ndpi_bitmask_set(&b, $BIT); ndpi_bitmask_is_set(&b, $BIT); [...] ndpi_bitmask_dealloc(&b); ``` See #2136
* Improved HTTP risk reportLuca Deri2025-06-08
| | | | PCRE2 is now enabled (if present) by default as necessary to report some HTTP risks
* First step into a dynamic number of protocols (#2857)Ivan Nardi2025-06-03
| | | | | | | | | | | | | We want to get rid of the defines `NDPI_MAX_SUPPORTED_PROTOCOLS` and `NDPI_MAX_NUM_CUSTOM_PROTOCOLS`. You can use: ``` ndpi_get_num_protocols() ``` See #2136 Removed some unused functions from public API
* New API to enable/disable protocols; remove ↵Ivan Nardi2025-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | `ndpi_set_protocol_detection_bitmask2()` (#2853) The main goal is not to have the bitmask depending on the total number of protocols anymore: `NDPI_INTERNAL_PROTOCOL_BITMASK` depends only on internal protocols, i.e. on `NDPI_MAX_INTERNAL_PROTOCOLS`, i.e. custom-defined protocols are not counted. See #2136 Keep the old data structure `NDPI_PROTOCOL_BITMASK` with the old semantic. Since we need to change the API (and all the application code...) anyway, simplify the API: by default all the protocols are enabled. If you need otherwise, please use `ndpi_init_detection_module_ext()` instead of `ndpi_init_detection_module()` (you can find an example in the `ndpiReader` code). To update the application code you likely only need to remove these 3 lines from your code: ``` - NDPI_PROTOCOL_BITMASK all; - NDPI_BITMASK_SET_ALL(all); - ndpi_set_protocol_detection_bitmask2(ndpi_str, &all); ``` Removed an unused field and struct definition.
* Added new APi callsLuca Deri2025-05-20
| | | | | | | - ndpi_is_master_only_protocol() - ndpi_normalize_protocol() These two APi calls are used to normalize mater/app nDPI protocols
* added raw tcp fingerprint to json (#2812)funesca2025-05-15
| | | | | | | | | | | * added raw tcp fingerprint to json * removed unnecessary change * fixed key for json * added configuration option for raw tcp fingerprint * fixed typos
* Follow-up of latest Signal call change (see: 4d41588a7)Ivan Nardi2025-04-05
|
* OS fingerprint code cleanupLuca Deri2025-03-31
|
* Added ndpi_str_to_utf8() API call to convert an ISO 8859 stirng to UTF-8Luca2025-03-27
|
* Improved configuration to enable/disable export of flow risk info (#2780)Ivan Nardi2025-03-25
| | | | Follow-up of f56831336334dddcff00eaf2132e5e0f226f0e32: now the configuration is for flow-risk, not global
* Added API calls to load TCP fingeprintsLuca Deri2025-03-25
| | | | | | | int ndpi_add_tcp_fingerprint(struct ndpi_detection_module_struct *ndpi_str, char *fingerprint, enum operating_system_hint os); int load_tcp_fingerprint_file_fd(struct ndpi_detection_module_struct *ndpi_str, FILE *fd); int ndpi_load_tcp_fingerprint_file(struct ndpi_detection_module_struct *ndpi_str, const char *path);
* Remove `NDPI_FULLY_ENCRYPTED` flow risk (#2779)Ivan Nardi2025-03-25
| | | | | | | Use `NDPI_OBFUSCATED_TRAFFIC` instead; this way, all the obfuscated traffic is identified via `NDPI_OBFUSCATED_TRAFFIC` flow risk. Disable fully-encryption detection by default, like all the obfuscation heuristics.
* Remove `NDPI_TLS_SUSPICIOUS_ESNI_USAGE` flow risk (#2778)Ivan Nardi2025-03-25
| | | | | | That flow risk was introduced in 79b89d286605635f15edfe3c21297aaa3b5f3acf but we can now use the generic `NDPI_TLS_SUSPICIOUS_EXTENSION` instead: ESNI is quite suspicious nowadays in itself (i.e. even without SNI). Note that ESNI support has been removed in cae9fb9989838f213eeb857b8fc4bbeac6940049
* Update ndpi_utils.cIvan Kapranov2025-03-11
|
* Add configuration parameter to enable/disable export of flow risk info (#2761)Ivan Nardi2025-03-05
| | | | For the most common protocols, avoid creating the string message if we are not going to use it
* Flow risk infos are always exported "in order" (by flow risk id)Ivan Nardi2025-03-04
| | | | | | | | This way, the `ndpiReader` output doesn't change if we change the internal logic about the order we set/check the various flow risks. Note that the flow risk *list* is already printed by `ndpiReader` in order.
