2018-08-29ppp: disable USB heuristic subdissector by defaultMartin Kaiser1-4/+10
Disable the PPP over USB heuristic subdisector by default. Clarify the comment about "compressed" address and control fields. Compressed means absent in this case. Therefore, the heuristic check for PPP over USB comes down to checking that the first byte is 0x7e. This is too weak and produces lots of false positives.

2017-01-10Rename tvb_new_subset() to tvb_new_subset_length_caplen().Guy Harris1-5/+5
This emphasizes that there is no such thing as *the* routine to construct a subset tvbuff; you need to choose one of tvb_new_subset_remaining() (if you want a new tvbuff that contains everything past a certain point in an existing tvbuff), tvb_new_subset_length() (if you want a subset that contains everything past a certain point, for some number of bytes, in an existing tvbuff), and tvb_new_subset_length_caplen() (for all other cases). Many of the calls to tvb_new_subset_length_caplen() should really be calling one of the other routines; that's the next step. (This also makes it easier to find the calls that need fixing.)

Add support for defragmentation of fragments that use the defragmentation scheme of PPP MP (RFC 1990). Instead of getting "sequence_number, fragment_number, last" as in other protocols, PPP MP provides a single sequence number that is effectively "seqnum + fragnum", though it provides flags for both the first and last fragment of a reassembly. See Appendix A of RFC 4623 (PWE3 Fragmentation and Reassembly) for a list of protocols that use this style, including PPP MP (RFC 1990), PWE3 MPLS (RFC 4385), L2TPv2 (RFC 2661), L2TPv3 (RFC 3931), ATM, and Frame Relay. Also add support for the Multi-class Extension to Multilink PPP (RFC 2686), which uses some of the previously reserved bits as classes that distinguish otherwise identical sequence numbers.

2016-08-31Don't do any Decode As stuff for dissector tables not used with Decode As.Guy Harris1-1/+1
Have all dissector tables have a "supports Decode As" flag, which defaults to FALSE, and which is set to TRUE if a register_decode_as() refers to it. When adding a dissector to a dissector table with a given key, only add it for Decode As if the dissector table supports it. For non-FT_STRING dissector tables, always check for multiple entries for the same protocol with different dissectors, and report an error if we found them. This means there's no need for the creator of a dissector table to specify whether duplicates of that sort should be allowed - we always do the check when registering something for "Decode As" (in a non-FT_STRING dissector table), and just don't bother registering anything for "Decode As" if the dissector table doesn't support "Decode As", so there's no check done for those dissector tables.

They are modeled after dissection dissector tables, but for the moment, don't have/need the flexibility. They are intended to be much simpler/faster than full dissection. The two most used/needed are "wtap_encap" and "ethertype", so they were the basis of starting to use and test capture dissector table API. Others may be added in the future. The "capture dissector" function signature needed a bit of tweeking to handling "claiming" of a packet. The current application of this is capture functions returning TRUE if they affected a "type" of packet count. Returning FALSE ends up considering the packet an "other" type.

2015-12-13Create a way to register "capture" dissectors.Michael Mann1-2/+5
Capture dissectors could be architected like dissection dissectors, with tables and subtables and possibly using tvbs to pass there data instead of raw byte arrays. This is a first step towards that by refactoring capture_info_packet() to work off of a "capture dissector table" Registering the capture dissection functions instead of calling them directly also clears up a bunch of dissector header files who sole purpose was providing the capture dissection function definition.

2015-12-10The Bridging Control Protocol is really two protocols.Guy Harris1-156/+184
RFC 3518 defines two protocols, one used to encapsulate bridged PDUs and one used to configure the bridging process. Make them two separately-registered protocols.

Some of the ASN.1 dissectors still generate a new_create_dissector_handle from the tool itself, so leave those for now.

2015-11-25PPP: RTP IPHC Compressed Non TCP packets and D bit zero packets (RFC 2507)John A. Thacker1-39/+172
Add support for RFC 2507 style IP Header Compression Compressed Non TCP packets (PPP protocol 0x0065). Also support RTP IPHC Full Header packets (protocol 0x0061) where the D bit is unset. Add expert info for when the D bit is unset but the sequence number is nonzero. Also fix an existing typo where the CUDP16 handle was being called for the CUDP8 "ethertype" for NDISWAN (very rare.)
