* Improved RTSP detection the second. (#1232)improved/rtsp_detection_the_secondToni Uhlig2021-07-06
| | | | | | | | * RTSP is no subprotocol of HTTP (most of the time) * detection patterns should stay in rtsp.c * set detected HTTP protocol only if at least a valid HTTP method detected Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* QUIC: add basic support for fragmented Client Hello (#1216)Ivan Nardi2021-06-24
| | | | Only in-order and non overlapping fragments are handled See #1195
* Speed and memory size optimisation (#1214)Vitaly Lavrov2021-06-23
| | | | | | | Removed bigram_automata, impossible_bigram_automata, trigram_automata. The ahocorasick structure is replaced with a bitmap. The bitmap size for ndpi_en_bigram is 176 bytes. The bitmap size for ndpi_en_trigram is 2201 bytes. On the test machine, the test execution time was reduced from 27.3 seconds to 24.7 (9%).

* Code review. (#1205)Vitaly Lavrov2021-06-15
| | | | | | | | | | | | | | | The common actions required to call the ac_automata_search() function have been moved to the ndpi_match_string_common function. This made it possible to simplify the ndpi_match_string, ndpi_match_string_protocol_id, ndpi_match_string_value, ndpi_match_custom_category, ndpi_match_string_subprotocol, ndpi_match_bigram, ndpi_match_trigram functions. Using u_int16_t type for protocol identifiers when working with the ahocorasick library (changes src/include/ndpi_api.h.in and src/include/ndpi_typedefs.h). Reworked "finalization" of all AC_AUTOMATA_t structures. Changing the order of fields in the ndpi_call_function_struct structure reduces the size of the ndpi_detection_module_struct structure by 10 kB (for x86_64).

* New version of the ahocorasick library (#1200)Vitaly Lavrov2021-06-07
| | | | | | | | | | | | | | | | The new version is about 25% faster with -O2 and 45% faster with -O3. No recursion is used (smaller stack size required). Uses less memory (by valgrind info) bigram: - original 1796 allocs, 247864 bytes allocated - new 1232 allocs, 158880 bytes allocated host_match: - original 18038 allocs, 3004576 bytes allocated - new 6861 allocs, 396624 bytes allocated The function ac_automata_search() is thread safe. Optional case-insensitive comparison. Matching at the beginning and at the end of the string is supported. One code file and one header file.
