* Merged protocols (now free to use) into existing categoriesLuca Deri2025-06-17
| | | | | - AdultContent -> Category Adult Content - LLM -> Category Artificial Intelligence
* Faster configuration (#2887)Ivan Nardi2025-06-17

* Prelimary work to remove `NDPI_LAST_IMPLEMENTED_PROTOCOL` (#2885)Ivan Nardi2025-06-16

* Add GLBP dissector (#2879)Vladimir Gavrilov2025-06-10
| | | GLBP is a Cisco proprietary first-hop redundancy protocol similar to HSRP and VRRP, but with additional load balancing capabilities.
* 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
* Dynamic allocation of `ndpi_struct->proto_defaults[]` (#2866)Ivan Nardi2025-06-06
| | | | | | | | Partial revert of 88bfe2cf0: in the trees we save the index and no more a pointer to `ndpi_struct->proto_defaults[]`. Remove same functions from public API See #2136
* 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.
* Add Hamachi protocol detection support (#2860)Vladimir Gavrilov2025-06-02

* A new interface for dissectors registration (#2843)Ivan Nardi2025-05-24
| | | | | | | | | | | | | | | | | | | | | We use `registr_dissector()` instead of `ndpi_set_bitmask_protocol_detection()`. Every file in `src/lib/protocols/*.c` is a dissector. Every dissector can handle multiple protocols. The real goal is this small change: ``` struct call_function_struct { - NDPI_PROTOCOL_BITMASK detection_bitmask; ``` i.e. getting rid of another protocol bitmask: this is mandatory to try to fix #2136 (see also e845e8205b68752c997d05224d8b2fd45acde714) As a nice side effect, we remove a bitmask comparison in the hot function `check_ndpi_detection_func()` TODO: change logging configuration from per-protocol to per-dissector
* Added the support for multiple TCP fingerprint formatLuca Deri2025-05-24
| | | | | | | | | - default (0) is the native nDPI format - MuonOF (1) has been added The format can be changed using metadata.tcp_fingerprint_format Added ability to identify mass scanners using TCP fingerprint

* Remove ProtonVPN address lists (#2831)Ivan Nardi2025-05-20
| | | | | | | Proton doesn't provide anymore the list of egress and ingress addresses. Remove the (stale) lists and the relative configuration parameters. See: https://www.reddit.com/r/ProtonVPN/comments/1k3lrl5/great_the_httpsapiprotonvpnchvpnlogicals_api_has/ See also 470a479eb

* Flow: keep track of "dissectors" (#2828)Ivan Nardi2025-05-19
| | | | | | In the flow, we should keep track of state of "dissectors", not "protocols". This way, flow structure doesn't depend anymore on the max number of protocols. This is also the first step into fixing #2136

* 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
* ICMP: move all the logic to the proper dissector fileIvan Nardi2025-02-28
| | | | | | | There are no reasons to keep entropy calculation and sanity checks code on the "guessing" algorithm. BTW, this change also fix the entropy calculation for non TCP/UDP/ICMP flows
* TOR: fix ip lists (#2748)Ivan Nardi2025-02-27
| | | | One list is from ingress nodes (used for protocol classification) and the second one is from exit nodes (used for flow risk check)

* DNS: rework adding entries to the FPC-DNS cache (#2730)Ivan Nardi2025-02-16
| | | | | Try to populate the FPC-DNS cache using directly the info from the current packet, and not from the metadata saved in `struct ndpi_flow_struct`. This will be important when adding monitoring support

* HTTP: add configuration for some metadata (#2704)Ivan Nardi2025-01-31
| | | Extend file configuration for just subclassification.
* Create a specific configuration for classification only (#2689)Ivan Nardi2025-01-31
| | | | | | | | | | | | | | | | | | | | | | | | In some scenarios, you might not be interested in flow metadata or flow-risks at all, but you might want only flow (sub-)classification. Examples: you only want to forward the traffic according to the classification or you are only interested in some protocol statistics. Create a new configuration file (for `ndpiReader`, but you can trivially adapt it for the library itself) allowing exactly that. You can use it via: `ndpiReader --conf=example/only_classification.conf ...` Note that this way, the nDPI overhead is lower because it might need less packets per flow: * TLS: nDPI processes only the CH (in most cases) and not also the SH and certificates * DNS: only the request is processed (instead of both request and response) We might extend the same "shortcut-logic" (stop processing the flow immediately when there is a final sub-classification) for others protocols. Add the configuration options to enable/disable the extraction of some TLS metadata.
