* Cosmetic changeLuca2022-07-12
|
* Keep track of how many dissectors calls we made for each flow (#1657)Ivan Nardi2022-07-11
|
* HTTP: improve detection of WindowsUpdate (#1658)Ivan Nardi2022-07-10
| | | | WindowsUpdate is also transported over HTTP, using a numeric IP as hostname (some kinds of CDN?)
* Remove unsafe access to `flow->protos` union (#1656)Ivan Nardi2022-07-10
| | | | | | We can access `flow->protos` only if we already have set a valid classification. It is quite likely that this code is never trigger, anyway.
* SNMP: fix detection (#1655)Ivan Nardi2022-07-10
| | | | | | We can write to `flow->protos` only when we are sure about SNMP classification. Use the generic wrapper to decode ASN1 BER integer
* SIP: improve detection (#1654)Ivan Nardi2022-07-09

* TFTP: fix memory access (#1653)Ivan Nardi2022-07-08

* LDAP: rewrite dissection (#1649)Ivan Nardi2022-07-08
|
* SMB: add (partial) support for messages split into multiple TCP segments (#1644)Ivan Nardi2022-07-07
|
* Avoid spurious calls to extra dissection (#1648)Ivan Nardi2022-07-07
| | | | If the extra callabck is not set, calling the extra dissection is only a waste of resources...
* SMTP: add support for X-ANONYMOUSTLS comamnd (#1650)Ivan Nardi2022-07-07
|
* Kerberos: add support for Krb-Error messages (#1647)Ivan Nardi2022-07-07
|
* Spotify: remove some useless ip ranges (#1646)Ivan Nardi2022-07-07
| | | | | | | These AS numbers are no more related to Spotify (or, if they are, they don't have any prefixes anyway). Even if we find some valid Spotify AS, we should handle them via the generic "autogenerated logic" used for every AS, and not in the dissector code.

| | | | | * TLSv1.3 UltraSurf flows are not detected by now Signed-off-by: Toni Uhlig <matzeton@googlemail.com>
* Add two new confidence values: confidence by partial DPI (#1632)Ivan Nardi2022-07-04
| | | | Used for all classifications based on partial/incomplete DPI information, i.e. all classifications done in `ndpi_detection_giveup()`.
* Update host content list match (#1633)Ivan Nardi2022-07-04
| | | | Improve classifications of Outlook, Cachefly, Cloudflare, Tiktok and Cybersecurity.

* TargusDataspeed: avoid false positives (#1628)Ivan Nardi2022-07-03
| | | | | TargusDataspeed dissector doesn't perform any real DPI checks but it only looks at the TCP/UDP ports. Delete it, and use standard logic to classify these flows by port.
* Update ASN/IPs lists (#1627)Ivan Nardi2022-07-03

* bins: add support for 64bit bins (#1626)Ivan Nardi2022-07-03

|
* Minor changes in how classification results are set (#1623)Ivan Nardi2022-07-03
| | | | | Protocol classification should always be set via `ndpi_set_detected_protocol()`: this way, the values in `flow->detected_protocol_stack[]` are always coherent.
* Usenet: improve dissection (#1622)Ivan Nardi2022-07-03
