* Telegram: improve identificationNardi Ivan2024-02-26
| | | | | | | | | | | | | | | | | Follow up of 31c706c3dbbf0afc4c8e0a6d0bb6f20796296549 and 75485e177ccc4fafcc62dd46c6917d5b735cf7d2. Allow fast classification by ip, but give time to other dissectors to kick in (for example, the TLS code for the Telegram Web flows). Even if we don't classify it anymore at the very first packet (i.e. SYN) we fully classify Telegram traffic at the first packet with payload, as *any* other protocol. This way, we always have the proper category, the proper confidence for the UDP flows and we don't overwrite previous classifications (TLS or ICMP) Remove old and stale identification logic for TCP flows

* Allow multiple `struct ndpi_detection_module_struct` to share some state (#2271)Ivan Nardi2024-02-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the concept of "global context". Right now every instance of `struct ndpi_detection_module_struct` (we will call it "local context" in this description) is completely independent from each other. This provide optimal performances in multithreaded environment, where we pin each local context to a thread, and each thread to a specific CPU core: we don't have any data shared across the cores. Each local context has, internally, also some information correlating **different** flows; something like: ``` if flow1 (PeerA <-> Peer B) is PROTOCOL_X; then flow2 (PeerC <-> PeerD) will be PROTOCOL_Y ``` To get optimal classification results, both flow1 and flow2 must be processed by the same local context. This is not an issue at all in the far most common scenario where there is only one local context, but it might be impractical in some more complex scenarios. Create the concept of "global context": multiple local contexts can use the same global context and share some data (structures) using it. This way the data correlating multiple flows can be read/write from different local contexts. This is an optional feature, disabled by default. Obviously data structures shared in a global context must be thread safe. This PR updates the code of the LRU implementation to be, optionally, thread safe. Right now, only the LRU caches can be shared; the other main structures (trees and automas) are basically read-only: there is little sense in sharing them. Furthermore, these structures don't have any information correlating multiple flows. Every LRU cache can be shared, independently from the others, via `ndpi_set_config(ndpi_struct, NULL, "lru.$CACHE_NAME.scope", "1")`. It's up to the user to find the right trade-off between performances (i.e. without shared data) and classification results (i.e. with some shared data among the local contexts), depending on the specific traffic patterns and on the algorithms used to balance the flows across the threads/cores/local contexts. Add some basic examples of library initialization in `doc/library_initialization.md`. This code needs libpthread as external dependency. It shouldn't be a big issue; however a configure flag has been added to disable global context support. A new CI job has been added to test it. TODO: we should need to find a proper way to add some tests on multithreaded enviroment... not an easy task... *** API changes *** If you are not interested in this feature, simply add a NULL parameter to any `ndpi_init_detection_module()` calls.

* New API for library configurationNardi Ivan2024-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the first step into providing (more) configuration options in nDPI. The idea is to have a simple way to configure (most of) nDPI: only one function (`ndpi_set_config()`) to set any configuration parameters (in the present or on in the future) and we try to keep this function prototype as agnostic as possible. You can configure the library: * via API, using `ndpi_set_config()` * via a configuration file, in a text format This way, anytime we need to add a new configuration parameter: * we don't need to add two public functions (a getter and a setter) * we don't break API/ABI compatibility of the library; even changing the parameter type (from integer to a list of integer, for example) doesn't break the compatibility. The complete list of configuration options is provided in `doc/configuration_parameters.md`. As a first example, two configuration knobs are provided: * the ability to enable/disable the extraction of the sha1 fingerprint of the TLS certificates. * the upper limit on the number of packets per flow that will be subject to inspection
* Added new API callsLuca2024-01-15
| | | | | | | | | | - ndpi_load_domain_suffixes() - ndpi_get_host_domain_suffix() whose goal is to find the domain name of a hostname. Example: www.bbc.co.uk -> co.uk mail.apple.com -> com
* Fix some warnings reported by CODESonar (#2227)Ivan Nardi2024-01-12
| | | | | | | | | | | | | | | | | | | Remove some unreached/duplicated code. Add error checking for `atoi()` calls. About `isdigit()` and similar functions. The warning reported is: ``` Negative Character Value help isdigit() is invoked here with an argument of signed type char, but only has defined behavior for int arguments that are either representable as unsigned char or equal to the value of macro EOF(-1). Casting the argument to unsigned char will avoid the undefined behavior. In a number of libc implementations, isdigit() is implemented using lookup tables (arrays): passing in a negative value can result in a read underrun. ``` Switching to our macros fix that. Add a check to `check_symbols.sh` to avoid using the original functions from libc.
