* ndpiReader: memory leak (#1215)Vitaly Lavrov2021-06-23
| | | | | | Non-critical bugs. If a file list is used, then all files except the last are not closed. Opening the next file loses the memory allocated via pcap_open_offline() for the previous file. If a bpf filter is used, then no memory is freed after pcap_compile.

* Refactored nDPI subprotocol handling and aimini protocol detection. (#1156)Toni2021-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Refactored and merged callback buffer routines for non-udp-tcp / udp / tcp / tcp-wo-payload. Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Try to detect one subprotocol if a detected protocol can have one. * 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> * Refactor subprotocol handling (1/2). Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Refactor subprotocol handling (2/2). Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Prevent some code duplication by using macros for ndpi_int_one_line_struct string comparision. Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Refactored aimini HTTP detection parts (somehow related to #1148). Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Added aimini client/server test pcap. Signed-off-by: Toni Uhlig <matzeton@googlemail.com> * Removed master protocol as it was only used for STUN and via also removed API function ndpi_get_protocol_id_master_proto * Adjusted Python code to conform to the changes made during the refactoring process.

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