* Fix parsing of ipv6 packets with extension headersNardi Ivan2021-09-19
| | | | | | | | Decoding of ipv6 traffic with extension headers was completely broken, since the beginning of the L4 header was always set to a wrong value. Handle the ipv6 fragments in the same way as the ipv4 ones: keep the first one and drop the others.
* Compile everything with "-W -Wall -Wno-unused-parameter" flags (#1276)Ivan Nardi2021-08-20
| | | | | | | | | | | | | | | | Fix all the warnings. Getting rid of "-Wno-unused-parameter" is quite complex because some parameters usage depends on compilation variable (i.e. `--enable-debug-messages`). The "-Werror" flag has been added only in Travis builds to avoid breaking the builds to users using uncommon/untested OS/compiler/enviroment. Tested on: * x86_64; Ubuntu 20.04; gcc 7,8,9,10,11; clang 7,8,9,10,11,12 * x86_64; CentOS 7.7; gcc 4.8.5 (with "--disable-gcrypt" flag) * Raspberry 4; Debian 10.10; gcc 8.3.0
* Fixed Mingw64 build, SonerCloud-CI and more. (#1273)Toni2021-08-18

Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Fixed Mingw64 build. * adapted to SonarCloud-CI workflow * removed broken and incomplete Windows example (tested on VS2017/VS2019) * removed unnecessary include (e.g. pthread.h for the library which does not make use of it) Signed-off-by: Toni Uhlig <matzeton@googlemail.com>

* ndpiReader: add statistics about nDPI performance (#1240)Ivan Nardi2021-07-13
| | | | | | | The goal is to have a (roughly) idea about how many packets nDPI needs to properly classify a flow. Log this information (and guessed flows number too) during unit tests, to keep track of improvements/regressions across commits.

| | | | | | | | | * 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

| | | | | | | | | | | | | | | * 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>
