* WHOIS: enhance detection, avoiding false positives (#1320)Ivan Nardi2021-10-05
| | | We are interested only in the domain name required, not in the long reply.
* Added -a <num> to ndpiReader for generating OPNsense configurationLuca Deri2021-10-04

* Fix how some protocols handle tcp retransmissions (#1321)Ivan Nardi2021-10-03
| | | | | | | Most (all?) protocols don't care about (tcp) retransmissions. If a protocol registers itself with a NDPI_SELECTION_BITMASK_PROTOCOL_*_WITHOUT_RETRANSMISSION value, its callback is never triggered with a retransmitted packet.

* Remove `detected_protocol_stack` field from `ndpi_packet_struct` (#1317)Ivan Nardi2021-09-29
| | | | | | | | | | | | | This field is an exact copy of `ndpi_flow_struct->detected_protocol_stack[2]`: * at the very beginning of packet dissection, the value saved in `flow->detected_protocol_stack` is copied in `packet->detected_protocol_stack` (via `ndpi_detection_process_packet()` -> `ndpi_init_packet_header()`) * every time we update `flow->detected_protocol_stack` we update `packet->detected_protocol_stack` too (via `ndpi_int_change_protocol()` -> `ndpi_int_change_packet_protocol()`) These two fields are always in sync: keeping the same value in two different places is useless.

| * FTP: fix support for START-TLS sessionsNardi Ivan2021-09-21
|/ | | | | | When TLS-over-FTP is used, the credentials are encrypted. So we must not wait for the username and the password commands, otherwise we elaborate a lot of packets for nothing.

| * 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.

* TLS: avoid zeroing large structures (#1300)Ivan Nardi2021-09-16
| | | | | | | | | | Zeroing large structures (i.e. size > KB) is quite costly (from a CPU point of view): we can safely avoid doing that for a couple of big structures. Standard and Valgrind tests have been diverging quite a lot: it is time to re-sync them. Use the same script and enable Valgrind via an enviroment variable: NDPI_TESTS_VALGRIND=1 ./tests/do.sh

* Bittorrent: fix a potential use-of-uninitialized-value error (#1296)Ivan Nardi2021-09-13
| | | | | | Not sure if this is the right fix (from a logical point-of-view): this code hasn't changed since OpenDPI era (!) and I have't found a trace triggering this code path. Anyway, the use-of-uninitialized-value error itself should be fixed.
