* TLS: allow sub-classification via ALPNNardi Ivan2022-10-20
| | | | | | | | In some rare cases, it is possible to sub-classify the flow via ALPN matching. This is particularly usefull for asymmetric traffic where the Client Hello doens't have the SNI. For the time being there is only one rule, about ANYDESK.

* TLS: explicit ignore client certificate (#1776)Ivan Nardi2022-10-18
| | | | | | | | | | | | | TLS classification usually stops after processing *server* certificates (if any). That means, that *client* certificate, if present, is usually ignored. However in some corner cases (i.e. unidirectional traffic) we might end up processing client certificate and exposing its metadata: the issue is that the application will think that this metadata are about the server and not about the client. So, for the time being, always ignore client certificate processing. As a future work, we might find an efficient way to process and export both certificates.
* Fix a use-of-uninitialized-value error on PCRE codeNardi Ivan2022-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is likely a false positive, triggered by the fact that libpcre is usually compiled without MASAN support. It it was a real error, ASAN would complain loudly with a invalid-free error at the end of the same function. ``` ==83793==WARNING: MemorySanitizer: use-of-uninitialized-value #0 0x562296111174 in ndpi_compile_rce_regex /home/ivan/svnrepos/nDPI/src/lib/ndpi_utils.c:1631:3 #1 0x5622960e3e4a in ndpi_is_rce_injection /home/ivan/svnrepos/nDPI/src/lib/ndpi_utils.c:1636:5 #2 0x5622960de7cd in ndpi_validate_url /home/ivan/svnrepos/nDPI/src/lib/ndpi_utils.c:1741:12 #3 0x5622960dae45 in ndpi_dpi2json /home/ivan/svnrepos/nDPI/src/lib/ndpi_utils.c:1362:29 #4 0x5622960e2751 in ndpi_flow2json /home/ivan/svnrepos/nDPI/src/lib/ndpi_utils.c:1512:10 #5 0x562296033b0f in process_ndpi_collected_info /home/ivan/svnrepos/nDPI/example/reader_util.c:1310:9 #6 0x5622960501f9 in packet_processing /home/ivan/svnrepos/nDPI/example/reader_util.c:1659:2 #7 0x562296045aef in ndpi_workflow_process_packet /home/ivan/svnrepos/nDPI/example/reader_util.c:2202:10 #8 0x562295e85374 in ndpi_process_packet /home/ivan/svnrepos/nDPI/example/ndpiReader.c:3937:7 #9 0x7f1235053466 (/lib/x86_64-linux-gnu/libpcap.so.0.8+0x23466) (BuildId: b84c893ea2516d6fb2c1c6726b1fe93b3be78f61) #10 0x7f1235041f67 in pcap_loop (/lib/x86_64-linux-gnu/libpcap.so.0.8+0x11f67) (BuildId: b84c893ea2516d6fb2c1c6726b1fe93b3be78f61) #11 0x562295e53139 in runPcapLoop /home/ivan/svnrepos/nDPI/example/ndpiReader.c:4060:15 #12 0x562295e51e7f in processing_thread /home/ivan/svnrepos/nDPI/example/ndpiReader.c:4130:3 #13 0x7f1234e53608 in start_thread /build/glibc-SzIz7B/glibc-2.31/nptl/pthread_create.c:477:8 #14 0x7f1234d2f132 in __clone /build/glibc-SzIz7B/glibc-2.31/misc/../sysdeps/unix/sysv/linux/x86_64/clone.S:95 Uninitialized value was created by an allocation of 'pcreErrorStr' in the stack frame #0 0x5622961108a6 in ndpi_compile_rce_regex /home/ivan/svnrepos/nDPI/src/lib/ndpi_utils.c:1603:3 ```

* TLS/DTLS: we process certificate for UDP flows, tooNardi Ivan2022-09-30

* Remove unused codeNardi Ivan2022-09-28
| | | | | | | | | LRU callbacks have been added in 460ff3c7a, but they have never been used and they have never been extended to the other LRU caches. `ndpi_search_tcp_or_udp()` basically returns the classification by port/ip of the flow; calling it from the dissector is useless.
