* 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.
