* Try to detect one subprotocol if a detected protocol can have one.fix/ndpi-subprotocol-detectionToni Uhlig2021-03-09
| | | | | | | * This adds a performance overhead due to much more protocol detection routine calls. See #1148 for more information. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* Add support for Snapchat voip calls (#1147)Ivan Nardi2021-03-06
| | | | | | | | | * Add support for Snapchat voip calls Snapchat multiplexes some of its audio/video real time traffic with QUIC sessions. The peculiarity of these sessions is that they are Q046 and don't have any SNI. * Fix tests with libgcrypt disabled
* Improved DGA detectionLuca Deri2021-03-03

| | | | | | | | | | | | | | | * Fixed memory leaks caused by conditional free'ing for some TLS connections. * Members of tls_quic struct should also free'd if the detected master protocol is IMAPS / POPS / SMTPS / etc. Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Prevent reader_util.c from exit()'ing if maximum flow count reached. This confuses the fuzzer. * Improved fuzz/Makefile.am to use LDADD for ../example/libndpiReader.a instead of LDFLAGS. That way, fuzz_ndpi_reader re-links to ../example/libndpiReader.a if something changed there. Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* QUIC: add suppport for DNS-over-QUIC (#1107)Ivan Nardi2021-01-07
| | | | | | | | | Even if it is only an early internet draft, DoQ has already (at least) one deployed implementation. See: https://www.zdnet.com/article/ad-blocker-adguard-deploys-worlds-first-dns-over-quic-resolver/ Draft: https://tools.ietf.org/html/draft-huitema-dprive-dnsoquic-00 In the future, if this protocol will be really used, it might be worth to rename NDPI_PROTOCOL_DOH_DOT in NDPI_PROTOCOL_DOH_DOT_DOQ
