* STUN: major code rework (#2116)Ivan Nardi2023-10-30
| | | | | | | | | | | | Try to have a faster classification, on first packet; use standard extra dissection data path for sub-classification, metadata extraction and monitoring. STUN caches: * use the proper confidence value * lookup into the caches only once per flow, after having found a proper STUN classification Add identification of Telegram VoIP calls.
* Custom rules: fix a stack overflow (#2128)Ivan Nardi2023-10-30

* Add `ndpi_domain_classify_finalize()` function (#2084)Ivan Nardi2023-09-12
| | | | | | | | | The "domain classify" data structure is immutable, since it uses "bitmap64". Allow to finalize it before starting to process packets (i.e. before calling `ndpi_domain_classify_contains()`) to avoid, in the data-path, all the memory allocations due to compression. Calling `ndpi_domain_classify_finalize()` is optional.
* tftp: check incrementation for DATA and ACK packetsThomas Winter2023-09-12
| | | | | | | | | | | | | The 2 bytes following the opcode for DATA and ACK packets are the block number and this should be incrementing every packet. We should check to see that this is occurring otherwise false matches can occur, eg L2TPv3 over UDP matches the DATA opcode but the next two bytes are always zero. Remove the DATA max block size assumption since this can be false if the blksize option is used to increase it. Fixes #2070
* tftp: check for Option AcknowledgementsThomas Winter2023-09-12
| | | | | | | | | TFTP Option Acknowledgement packets were being excluded. When a read/write request contains options, an Option Acknowledgement is returned that contains the option strings that the transaction will use. The options sent in the request are not compared with what was acknowledged.
* tftp: rework request checking to account for optionsThomas Winter2023-09-12
| | | | | | | | | | | | | | | | | Read and write requests were not handling options. The existing code inspecting request messages assumed that the string before the end of the payload was the mode and that the filename length depended on the mode length. However the first two strings are the filename and mode which can be followed by any number of option strings. Rework the checking of the filename and mode to just search the first two strings which should always exist. Any options after that are ignored. Absence of the filename or mode is now excludes the TFTP protocol. Absence of the filename no longer is considered malformed packet because it can match other protocols falsely.
* Fixes matches with domain name strings that start with a dotLuca Deri2023-09-11
